## Dovecot configuration file # If you're in a hurry, see http://wiki.dovecot.org/QuickConfiguration # "doveconf -n" command gives a clean output of the changed settings. Use it # instead of copy&pasting files when posting to the Dovecot mailing list. # '#' character and everything after it is treated as comments. Extra spaces # and tabs are ignored. If you want to use either of these explicitly, put the # value inside quotes, eg.: key = "# char and trailing whitespace " # Default values are shown for each setting, it's not required to uncomment # those. These are exceptions to this though: No sections (e.g. namespace {}) # or plugin settings are added by default, they're listed only as examples. # Paths are also just examples with the real defaults being based on configure # options. The paths listed here are for configure --prefix=/usr # --sysconfdir=/etc --localstatedir=/var # Protocols we want to be serving. protocols = imap pop3 lmtp # A comma separated list of IPs or hosts where to listen in for connections. # "*" listens in all IPv4 interfaces, "::" listens in all IPv6 interfaces. # If you want to specify non-default ports or anything more complex, # edit conf.d/master.conf. listen = * # Base directory where to store runtime data. #base_dir = /var/run/dovecot/ # Greeting message for clients. #login_greeting = Dovecot ready. # Space separated list of trusted network ranges. Connections from these # IPs are allowed to override their IP addresses and ports (for logging and # for authentication checks). disable_plaintext_auth is also ignored for # these networks.

Currently shows user name and # IP address. Useful for seeing who are actually using the IMAP processes # (eg. shared mailboxes or if same uid is used for multiple accounts). #verbose_proctitle = no # Should all processes be killed when Dovecot master process shuts down. # Setting this to "no" means that Dovecot can be upgraded without # forcing existing client connections to close (although that could also be # a problem if the upgrade is e.g. because of a security fix). #shutdown_clients = yes # If non-zero, run mail commands via this many connections to doveadm server, # instead of running them directly in the same process. #doveadm_worker_count = 0 # UNIX socket or host:port used for connecting to doveadm server #doveadm_socket_path = doveadm-server ## ## Dictionary server settings ## # Dictionary can be used to store key=value lists. This is used by several # plugins. The dictionary can be accessed either directly or though a # dictionary server. The following dict block maps dictionary names to URIs # when the server is used. These can then be referenced using URIs in format # "proxy::<name>". dict { #quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext #expire = sqlite:/etc/dovecot/dovecot-dict-sql.conf.ext } # Most of the actual configuration gets included below.

The 00-prefixes # in filenames are intended to make it easier to understand the ordering. !include conf.d/*.conf # A config file can also tried to be included without giving an error if # it's not found: #!include_try /etc/dovecot/local.conf
## ## SSL settings ## # SSL/TLS support: yes, no, required. <doc/wiki/SSL.txt> ssl = required # PEM encoded X.509 SSL/TLS certificate and private key. They're opened before # dropping root privileges, so keep the key file unreadable by anyone but # root.

Alternatively # give it when starting dovecot with -p parameter. Since this file is often # world-readable, you may want to place this setting instead to a different # root owned 0600 file by using ssl_key_password = <path. #ssl_key_password = # PEM encoded trusted certificate authority. Set this only if you intend to use # ssl_verify_client_cert=yes. The file should contain the CA certificate(s) # followed by the matching CRL(s).

## ## Mailbox locations and namespaces ## # Location for users' mailboxes. The default is empty, which means that Dovecot # tries to find the mailboxes automatically. This won't work if the user # doesn't yet have any mail, so you should explicitly tell Dovecot the full # location. # # If you're using mbox, giving a path to the INBOX file (eg. /var/mail/%u) # isn't enough. You'll also need to tell Dovecot where the other mailboxes are # kept. This is called the "root mail directory", and it must be the first # path given in the mail_location setting. # # There are a few special variables you can use, eg.: # # %u - username # %n - user part in user@domain, same as %u if there's no domain # %d - domain part in user@domain, empty if there's no domain # %h - home directory # # See doc/wiki/Variables.txt for full list. Some examples: # # mail_location = maildir:~/Maildir # mail_location = mbox:~/mail:INBOX=/var/mail/%u # mail_location = mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n # # <doc/wiki/MailLocation.txt> # mail_location = mail_location = maildir:~ # If you need to set multiple mailbox locations or want to change default # namespace settings, you can do it by defining namespace sections. # # You can have private, shared and public namespaces. Private namespaces # are for user's personal mails. Shared namespaces are for accessing other # users' mailboxes that have been shared. Public namespaces are for shared # mailboxes that are managed by sysadmin. If you create any shared or public # namespaces you'll typically want to enable ACL plugin also, otherwise all # users can access all the shared mailboxes, assuming they have permissions # on filesystem level to do so. # # REMEMBER: If you add any namespaces, the default namespace must be added # explicitly, ie. mail_location does nothing unless you have a namespace # without a location setting. Default namespace is simply done by having a # namespace with empty prefix. #namespace { # Namespace type: private, shared or public #type = private # Hierarchy separator to use. You should use the same separator for all # namespaces or some clients get confused. '/' is usually a good one. # The default however depends on the underlying mail storage format. #separator = # Prefix required to access this namespace. This needs to be different for # all namespaces. For example "Public/". #prefix = # Physical location of the mailbox. This is in same format as # mail_location, which is also the default for it. #location = # There can be only one INBOX, and this setting defines which namespace # has it. #inbox = no # If namespace is hidden, it's not advertised to clients via NAMESPACE # extension. You'll most likely also want to set list=no. This is mostly # useful when converting from another server with different namespaces which # you want to deprecate but still keep working. For example you can create # hidden namespaces with prefixes "~/mail/", "~%u/mail/" and "mail/". #hidden = no # Show the mailboxes under this namespace with LIST command. This makes the # namespace visible for clients that don't support NAMESPACE extension. # "children" value lists child mailboxes, but hides the namespace prefix. #list = yes # Namespace handles its own subscriptions. If set to "no", the parent # namespace handles them (empty prefix should always have this as "yes") #subscriptions = yes #} # Example shared namespace configuration #namespace { #type = shared #separator = / # Mailboxes are visible under "shared/user@domain/" # %%n, %%d and %%u are expanded to the destination user. #prefix = shared/%%u/ # Mail location for other users' mailboxes. Note that %variables and ~/ # expands to the logged in user's data. %%n, %%d, %%u and %%h expand to the # destination user's data. #location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u # Use the default namespace for saving subscriptions. #subscriptions = no # List the shared/ namespace only if there are visible shared mailboxes. #list = children #} # System user and group used to access mails. If you use multiple, userdb # can override these by returning uid or gid fields. You can use either numbers # or names. <doc/wiki/UserIds.txt> #mail_uid = #mail_gid = # Group to enable temporarily for privileged operations. Currently this is # used only with INBOX when either its initial creation or dotlocking fails. # Typically this is set to "mail" to give access to /var/mail. #mail_privileged_group = # Grant access to these supplementary groups for mail processes. Typically # these are used to set up access to shared mailboxes. Note that it may be # dangerous to set these if users can create symlinks (e.g. if "mail" group is # set here, ln -s /var/mail ~/mail/var could allow a user to delete others' # mailboxes, or ln -s /secret/shared/box ~/mail/mybox would allow reading it). #mail_access_groups = # Allow full filesystem access to clients.

It works with both # maildir and mboxes, allowing you to prefix mailboxes names with eg. /path/ # or ~user/. #mail_full_filesystem_access = no ## ## Mail processes ## # Don't use mmap() at all. This is required if you store indexes to shared # filesystems (NFS or clustered filesystem). #mmap_disable = no # Rely on O_EXCL to work when creating dotlock files.

Set this to yes to make Dovecot flush NFS caches # whenever needed. If you're using only a single mail server this isn't needed. #mail_nfs_storage = no # Mail index files also exist in NFS. Setting this to yes requires # mmap_disable=yes and fsync_disable=no. #mail_nfs_index = no # Locking method for index files.

Usually this should be done only if you don't # allow shell access for users. <doc/wiki/Chrooting.txt> #valid_chroot_dirs = # Default chroot directory for mail processes. This can be overridden for # specific users in user database by giving /./ in user's home directory # (eg. /home/./user chroots into /home). Note that usually there is no real # need to do chrooting, Dovecot doesn't allow users to access files outside # their mail directory anyway. If your home directories are prefixed with # the chroot directory, append "/." to mail_chroot. <doc/wiki/Chrooting.txt> #mail_chroot = # UNIX socket path to master authentication server to find users. # This is used by imap (for shared users) and lda. #auth_socket_path = /var/run/dovecot/auth-userdb # Directory where to look up mail plugins. #mail_plugin_dir = /usr/lib/dovecot # Space separated list of plugins to load for all services. Plugins specific to # IMAP, LDA, etc. are added to this list in their own .conf files. #mail_plugins = ## ## Mailbox handling optimizations ## # The minimum number of mails in a mailbox before updates are done to cache # file. This allows optimizing Dovecot's behavior to do less disk writes at # the cost of more disk reads. #mail_cache_min_mail_count = 0 # When IDLE command is running, mailbox is checked once in a while to see if # there are any new mails or other changes. This setting defines the minimum # time to wait between those checks. Dovecot can also use dnotify, inotify and # kqueue to find out immediately when changes occur. #mailbox_idle_check_interval = 30 secs # Save mails with CR+LF instead of plain LF. This makes sending those mails # take less CPU, especially with sendfile() syscall with Linux and FreeBSD. # But it also creates a bit more disk I/O which may just make it slower. # Also note that if other software reads the mboxes/maildirs, they may handle # the extra CRs wrong and cause problems. #mail_save_crlf = no ## ## Maildir-specific settings ## # By default LIST command returns all entries in maildir beginning with a dot. # Enabling this option makes Dovecot return only entries which are directories. # This is done by stat()ing each entry, so it causes more disk I/O. # (For systems setting struct dirent->d_type, this check is free and it's # done always regardless of this setting) #maildir_stat_dirs = no # When copying a message, do it with hard links whenever possible. This makes # the performance much better, and it's unlikely to have any side effects. #maildir_copy_with_hardlinks = yes # Assume Dovecot is the only MUA accessing Maildir: Scan cur/ directory only # when its mtime changes unexpectedly or when we can't find the mail otherwise. #maildir_very_dirty_syncs = no ## ## mbox-specific settings ## # Which locking methods to use for locking mbox. There are four available: # dotlock: Create <mailbox>.lock file. This is the oldest and most NFS-safe # solution. If you want to use /var/mail/ like directory, the users # will need write access to that directory. # dotlock_try: Same as dotlock, but if it fails because of permissions or # because there isn't enough disk space, just skip it. # fcntl : Use this if possible. Works with NFS too if lockd is used. # flock : May not exist in all systems. Doesn't work with NFS. # lockf : May not exist in all systems. Doesn't work with NFS. # # You can use multiple locking methods; if you do the order they're declared # in is important to avoid deadlocks if other MTAs/MUAs are using multiple # locking methods as well. Some operating systems don't allow using some of # them simultaneously. #mbox_read_locks = fcntl #mbox_write_locks = dotlock fcntl mbox_write_locks = fcntl # Maximum time to wait for lock (all of them) before aborting. #mbox_lock_timeout = 5 mins # If dotlock exists but the mailbox isn't modified in any way, override the # lock file after this much time. #mbox_dotlock_change_timeout = 2 mins # When mbox changes unexpectedly we have to fully read it to find out what # changed. If the mbox is large this can take a long time. Since the change # is usually just a newly appended mail, it'd be faster to simply read the # new mails. If this setting is enabled, Dovecot does this but still safely # fallbacks to re-reading the whole mbox file whenever something in mbox isn't # how it's expected to be. The only real downside to this setting is that if # some other MUA changes message flags, Dovecot doesn't notice it immediately. # Note that a full sync is done with SELECT, EXAMINE, EXPUNGE and CHECK # commands. #mbox_dirty_syncs = yes # Like mbox_dirty_syncs, but don't do full syncs even with SELECT, EXAMINE, # EXPUNGE or CHECK commands. If this is set, mbox_dirty_syncs is ignored. #mbox_very_dirty_syncs = no # Delay writing mbox headers until doing a full write sync (EXPUNGE and CHECK # commands and when closing the mailbox).

# Global Postfix configuration file. This file lists only a subset # of all parameters. For the syntax, and for a complete parameter # list, see the postconf(5) manual page (command: "man 5 postconf"). # # For common configuration examples, see BASIC_CONFIGURATION_README # and STANDARD_CONFIGURATION_README. To find these documents, use # the command "postconf html_directory readme_directory", or go to # http://www.postfix.org/. # # For best results, change no more than 2-3 parameters at a time, # and test if Postfix still works after every change. # SOFT BOUNCE # # The soft_bounce parameter provides a limited safety net for # testing. When soft_bounce is enabled, mail will remain queued that # would otherwise bounce. This parameter disables locally-generated # bounces, and prevents the SMTP server from rejecting mail permanently # (by changing 5xx replies into 4xx replies). However, soft_bounce # is no cure for address rewriting mistakes or mail routing mistakes. # #soft_bounce = no # LOCAL PATHNAME INFORMATION # # The queue_directory specifies the location of the Postfix queue. # This is also the root directory of Postfix daemons that run chrooted. # See the files in examples/chroot-setup for setting up Postfix chroot # environments on different UNIX systems. # queue_directory = /var/spool/postfix # The command_directory parameter specifies the location of all # postXXX commands. # command_directory = /usr/sbin # The daemon_directory parameter specifies the location of all Postfix # daemon programs (i.e. programs listed in the master.cf file). This # directory must be owned by root. # daemon_directory = /usr/libexec/postfix # The data_directory parameter specifies the location of Postfix-writable # data files (caches, random numbers). This directory must be owned # by the mail_owner account (see below). # data_directory = /var/lib/postfix # QUEUE AND PROCESS OWNERSHIP # # The mail_owner parameter specifies the owner of the Postfix queue # and of most Postfix daemon processes. Specify the name of a user # account THAT DOES NOT SHARE ITS USER OR GROUP ID WITH OTHER ACCOUNTS # AND THAT OWNS NO OTHER FILES OR PROCESSES ON THE SYSTEM. In # particular, don't specify nobody or daemon. PLEASE USE A DEDICATED # USER. # mail_owner = postfix # The default_privs parameter specifies the default rights used by # the local delivery agent for delivery to external file or command. # These rights are used in the absence of a recipient user context. # DO NOT SPECIFY A PRIVILEGED USER OR THE POSTFIX OWNER. # #default_privs = nobody # INTERNET HOST AND DOMAIN NAMES # # The myhostname parameter specifies the internet hostname of this # mail system. The default is to use the fully-qualified domain name # from gethostname(). $myhostname is used as a default value for many # other configuration parameters. # #myhostname = host.domain.tld #myhostname = virtual.domain.tld # The mydomain parameter specifies the local internet domain name. # The default is to use $myhostname minus the first component. # $mydomain is used as a default value for many other configuration # parameters. # #mydomain = domain.tld # SENDING MAIL # # The myorigin parameter specifies the domain that locally-posted # mail appears to come from. The default is to append $myhostname, # which is fine for small sites. If you run a domain with multiple # machines, you should (1) change this to $mydomain and (2) set up # a domain-wide alias database that aliases each user to # user@that.users.mailhost. # # For the sake of consistency between sender and recipient addresses, # myorigin also specifies the default domain name that is appended # to recipient addresses that have no @domain part. # #myorigin = $myhostname #myorigin = $mydomain # RECEIVING MAIL # The inet_interfaces parameter specifies the network interface # addresses that this mail system receives mail on. By default, # the software claims all active interfaces on the machine. The # parameter also controls delivery of mail to user@[ip.address]. # # See also the proxy_interfaces parameter, for network addresses that # are forwarded to us via a proxy or network address translator. # # Note: you need to stop/start Postfix when this parameter changes. # #inet_interfaces = all #inet_interfaces = $myhostname #inet_interfaces = $myhostname, localhost inet_interfaces = localhost # Enable IPv4, and IPv6 if supported inet_protocols = all # The proxy_interfaces parameter specifies the network interface # addresses that this mail system receives mail on by way of a # proxy or network address translation unit.

By default, that is the UNIX # compatible delivery agent that lookups all recipients in /etc/passwd # and /etc/aliases or their equivalent. # # The default is $myhostname + localhost.$mydomain. On a mail domain # gateway, you should also include $mydomain. # # Do not specify the names of virtual domains - those domains are # specified elsewhere (see VIRTUAL_README). # # Do not specify the names of domains that this machine is backup MX # host for. Specify those names via the relay_domains settings for # the SMTP server, or use permit_mx_backup if you are lazy (see # STANDARD_CONFIGURATION_README). # # The local machine is always the final destination for mail addressed # to user@[the.net.work.address] of an interface that the mail system # receives mail on (see the inet_interfaces parameter). # # Specify a list of host or domain names, /file/name or type:table # patterns, separated by commas and/or whitespace.

This parameter is defined by default. # # To turn off local recipient checking in the SMTP server, specify # local_recipient_maps = (i.e. empty). # # The default setting assumes that you use the default Postfix local # delivery agent for local delivery. You need to update the # local_recipient_maps setting if: # # - You define $mydestination domain recipients in files other than # /etc/passwd, /etc/aliases, or the $virtual_alias_maps files. # For example, you define $mydestination domain recipients in # the $virtual_mailbox_maps files. # # - You redefine the local delivery agent in master.cf. # # - You redefine the "local_transport" setting in main.cf. # # - You use the "luser_relay", "mailbox_transport", or "fallback_transport" # feature of the Postfix local delivery agent (see local(8)). # # Details are described in the LOCAL_RECIPIENT_README file. # # Beware: if the Postfix SMTP server runs chrooted, you probably have # to access the passwd file via the proxymap service, in order to # overcome chroot restrictions. The alternative, having a copy of # the system passwd file in the chroot jail is just not practical. # # The right-hand side of the lookup tables is conveniently ignored. # In the left-hand side, specify a bare username, an @domain.tld # wild-card, or specify a user@domain.tld address. # #local_recipient_maps = unix:passwd.byname $alias_maps #local_recipient_maps = proxy:unix:passwd.byname $alias_maps #local_recipient_maps = # The unknown_local_recipient_reject_code specifies the SMTP server # response code when a recipient domain matches $mydestination or # ${proxy,inet}_interfaces, while $local_recipient_maps is non-empty # and the recipient address or address local-part is not found. # # The default setting is 550 (reject mail) but it is safer to start # with 450 (try again later) until you are certain that your # local_recipient_maps settings are OK. # unknown_local_recipient_reject_code = 550 # TRUST AND RELAY CONTROL # The mynetworks parameter specifies the list of "trusted" SMTP # clients that have more privileges than "strangers". # # In particular, "trusted" SMTP clients are allowed to relay mail # through Postfix. See the smtpd_recipient_restrictions parameter # in postconf(5). # # You can specify the list of "trusted" network addresses by hand # or you can let Postfix do it for you (which is the default). # # By default (mynetworks_style = subnet), Postfix "trusts" SMTP # clients in the same IP subnetworks as the local machine. # On Linux, this does works correctly only with interfaces specified # with the "ifconfig" command. # # Specify "mynetworks_style = class" when Postfix should "trust" SMTP # clients in the same IP class A/B/C networks as the local machine. # Don't do this with a dialup site - it would cause Postfix to "trust" # your entire provider's network. Instead, specify an explicit # mynetworks list by hand, as described below. # # Specify "mynetworks_style = host" when Postfix should "trust" # only the local machine. # #mynetworks_style = class #mynetworks_style = subnet #mynetworks_style = host # Alternatively, you can specify the mynetworks list by hand, in # which case Postfix ignores the mynetworks_style setting. # # Specify an explicit list of network/netmask patterns, where the # mask specifies the number of bits in the network part of a host # address. # # You can also specify the absolute pathname of a pattern file instead # of listing the patterns here.

Continue # long lines by starting the next line with whitespace. A file name # is replaced by its contents; a type:name table is matched when a # (parent) domain appears as lookup key. # # NOTE: Postfix will not automatically forward mail for domains that # list this system as their primary or backup MX host. See the # permit_mx_backup restriction description in postconf(5). # #relay_domains = $mydestination # INTERNET OR INTRANET # The relayhost parameter specifies the default host to send mail to # when no entry is matched in the optional transport(5) table. When # no relayhost is given, mail is routed directly to the destination. # # On an intranet, specify the organizational domain name. If your # internal DNS uses no MX records, specify the name of the intranet # gateway host instead. # # In the case of SMTP, specify a domain, host, host:port, [host]:port, # [address] or [address]:port; the form [host] turns off MX lookups. # # If you're connected via UUCP, see also the default_transport parameter. # #relayhost = $mydomain #relayhost = [gateway.my.domain] #relayhost = [mailserver.isp.tld] #relayhost = uucphost #relayhost = [an.ip.add.ress] # REJECTING UNKNOWN RELAY USERS # # The relay_recipient_maps parameter specifies optional lookup tables # with all addresses in the domains that match $relay_domains. # # If this parameter is defined, then the SMTP server will reject # mail for unknown relay users.

This feature is turned on by default, although it # still needs further development (it's disabled on SCO UNIX due # to an SCO bug). # # A Postfix process will pause for $in_flow_delay seconds before # accepting a new message, when the message arrival rate exceeds the # message delivery rate. With the default 100 SMTP server process # limit, this limits the mail inflow to 100 messages a second more # than the number of messages delivered per second. # # Specify 0 to disable the feature.

# VIRTUAL(5) VIRTUAL(5) # # NAME # virtual - Postfix virtual alias table format # # SYNOPSIS # postmap /etc/postfix/virtual # # postmap -q "string" /etc/postfix/virtual # # postmap -q - /etc/postfix/virtual <inputfile # # DESCRIPTION # The optional virtual(5) alias table rewrites recipient # addresses for all local, all virtual, and all remote mail # destinations. This is unlike the aliases(5) table which # is used only for local(8) delivery. Virtual aliasing is # recursive, and is implemented by the Postfix cleanup(8) # daemon before mail is queued. # # The main applications of virtual aliasing are: # # o To redirect mail for one address to one or more # addresses. # # o To implement virtual alias domains where all # addresses are aliased to addresses in other # domains. # # Virtual alias domains are not to be confused with # the virtual mailbox domains that are implemented # with the Postfix virtual(8) mail delivery agent. # With virtual mailbox domains, each recipient # address can have its own mailbox. # # Virtual aliasing is applied only to recipient envelope # addresses, and does not affect message headers. Use # canonical(5) mapping to rewrite header and envelope # addresses in general. # # Normally, the virtual(5) alias table is specified as a # text file that serves as input to the postmap(1) command. # The result, an indexed file in dbm or db format, is used # for fast searching by the mail system. Execute the command # "postmap /etc/postfix/virtual" to rebuild an indexed file # after changing the corresponding text file. # # When the table is provided via other means such as NIS, # LDAP or SQL, the same lookups are done as for ordinary # indexed files. # # Alternatively, the table can be provided as a regular- # expression map where patterns are given as regular expres- # sions, or lookups can be directed to TCP-based server. In # those case, the lookups are done in a slightly different # way as described below under "REGULAR EXPRESSION TABLES" # or "TCP-BASED TABLES". # # CASE FOLDING # The search string is folded to lowercase before database # lookup. As of Postfix 2.3, the search string is not case # folded with database types such as regexp: or pcre: whose # lookup fields can match both upper and lower case. # # TABLE FORMAT # The input format for the postmap(1) command is as follows: # # pattern result # When pattern matches a mail address, replace it by # the corresponding result. # # blank lines and comments # Empty lines and whitespace-only lines are ignored, # as are lines whose first non-whitespace character # is a `#'. # # multi-line text # A logical line starts with non-whitespace text. A # line that starts with whitespace continues a logi- # cal line. # # TABLE SEARCH ORDER # With lookups from indexed files such as DB or DBM, or from # networked tables such as NIS, LDAP or SQL, patterns are # tried in the order as listed below: # # user@domain address, address, ... # Redirect mail for user@domain to address. This # form has the highest precedence. # # user address, address, ... # Redirect mail for user@site to address when site is # equal to $myorigin, when site is listed in $mydes- # tination, or when it is listed in $inet_interfaces # or $proxy_interfaces. # # This functionality overlaps with functionality of # the local aliases(5) database. The difference is # that virtual(5) mapping can be applied to non-local # addresses. # # @domain address, address, ... # Redirect mail for other users in domain to address. # This form has the lowest precedence. # # Note: @domain is a wild-card. With this form, the # Postfix SMTP server accepts mail for any recipient # in domain, regardless of whether that recipient # exists. This may turn your mail system into a # backscatter source: Postfix first accepts mail for # non-existent recipients and then tries to return # that mail as "undeliverable" to the often forged # sender address. # # RESULT ADDRESS REWRITING # The lookup result is subject to address rewriting: # # o When the result has the form @otherdomain, the # result becomes the same user in otherdomain. This # works only for the first address in a multi-address # lookup result. # # o When "append_at_myorigin=yes", append "@$myorigin" # to addresses without "@domain". # # o When "append_dot_mydomain=yes", append ".$mydomain" # to addresses without ".domain". # # ADDRESS EXTENSION # When a mail address localpart contains the optional recip- # ient delimiter (e.g., user+foo@domain), the lookup order # becomes: user+foo@domain, user@domain, user+foo, user, and # @domain. # # The propagate_unmatched_extensions parameter controls # whether an unmatched address extension (+foo) is propa- # gated to the result of table lookup. # # VIRTUAL ALIAS DOMAINS # Besides virtual aliases, the virtual alias table can also # be used to implement virtual alias domains. With a virtual # alias domain, all recipient addresses are aliased to # addresses in other domains. # # Virtual alias domains are not to be confused with the vir- # tual mailbox domains that are implemented with the Postfix # virtual(8) mail delivery agent. With virtual mailbox # domains, each recipient address can have its own mailbox. # # With a virtual alias domain, the virtual domain has its # own user name space. Local (i.e. non-virtual) usernames # are not visible in a virtual alias domain. In particular, # local aliases(5) and local mailing lists are not visible # as localname@virtual-alias.domain. # # Support for a virtual alias domain looks like: # # /etc/postfix/main.cf: # virtual_alias_maps = hash:/etc/postfix/virtual # # Note: some systems use dbm databases instead of hash. See # the output from "postconf -m" for available database # types. # # /etc/postfix/virtual: # virtual-alias.domain anything (right-hand content does not matter) # postmaster@virtual-alias.domain postmaster # user1@virtual-alias.domain address1 # user2@virtual-alias.domain address2, address3 # # The virtual-alias.domain anything entry is required for a # virtual alias domain. Without this entry, mail is rejected # with "relay access denied", or bounces with "mail loops # back to myself". # # Do not specify virtual alias domain names in the main.cf # mydestination or relay_domains configuration parameters. # # With a virtual alias domain, the Postfix SMTP server # accepts mail for known-user@virtual-alias.domain, and # rejects mail for unknown-user@virtual-alias.domain as # undeliverable. # # Instead of specifying the virtual alias domain name via # the virtual_alias_maps table, you may also specify it via # the main.cf virtual_alias_domains configuration parameter. # This latter parameter uses the same syntax as the main.cf # mydestination configuration parameter. # # REGULAR EXPRESSION TABLES # This section describes how the table lookups change when # the table is given in the form of regular expressions. For # a description of regular expression lookup table syntax, # see regexp_table(5) or pcre_table(5). # # Each pattern is a regular expression that is applied to # the entire address being looked up. Thus, user@domain mail # addresses are not broken up into their user and @domain # constituent parts, nor is user+foo broken up into user and # foo. # # Patterns are applied in the order as specified in the ta- # ble, until a pattern is found that matches the search # string. # # Results are the same as with indexed file lookups, with # the additional feature that parenthesized substrings from # the pattern can be interpolated as $1, $2 and so on. # # TCP-BASED TABLES # This section describes how the table lookups change when # lookups are directed to a TCP-based server. For a descrip- # tion of the TCP client/server lookup protocol, see tcp_ta- # ble(5). This feature is not available up to and including # Postfix version 2.4. # # Each lookup operation uses the entire address once. Thus, # user@domain mail addresses are not broken up into their # user and @domain constituent parts, nor is user+foo broken # up into user and foo. # # Results are the same as with indexed file lookups. # # BUGS # The table format does not understand quoting conventions. # # CONFIGURATION PARAMETERS # The following main.cf parameters are especially relevant # to this topic. See the Postfix main.cf file for syntax # details and for default values. Use the "postfix reload" # command after a configuration change. # # virtual_alias_maps # List of virtual aliasing tables. # # virtual_alias_domains # List of virtual alias domains. This uses the same # syntax as the mydestination parameter. # # propagate_unmatched_extensions # A list of address rewriting or forwarding mecha- # nisms that propagate an address extension from the # original address to the result. Specify zero or # more of canonical, virtual, alias, forward, # include, or generic. # # Other parameters of interest: # # inet_interfaces # The network interface addresses that this system # receives mail on. You need to stop and start Post- # fix when this parameter changes. # # mydestination # List of domains that this mail system considers # local. # # myorigin # The domain that is appended to any address that # does not have a domain. # # owner_request_special # Give special treatment to owner-xxx and xxx-request # addresses. # # proxy_interfaces # Other interfaces that this machine receives mail on # by way of a proxy agent or network address transla- # tor. # # SEE ALSO # cleanup(8), canonicalize and enqueue mail # postmap(1), Postfix lookup table manager # postconf(5), configuration parameters # canonical(5), canonical address mapping # # README FILES # Use "postconf readme_directory" or "postconf html_direc- # tory" to locate this information. # ADDRESS_REWRITING_README, address rewriting guide # DATABASE_README, Postfix lookup table overview # VIRTUAL_README, domain hosting guide # # LICENSE # The Secure Mailer license must be distributed with this # software. # # AUTHOR(S) # Wietse Venema # IBM T.J.

/etc/dovecot/passwd の情報が、メーラーからサーバーにアクセスする時に使う情報。 パスワードは doveadm pw -s SHA256-CRYPT で作る。 この場合はナントカ@fushiahra.org でパスワードが前述のでログインすると/var/spool/mail/vhosts/catch-all/Maildir 以下の情報をダウンロード出来る
/etc/postfix/virtual が受信したメールのマッチングが行われる所？ 例えば適当な@fushihara.orgにメールが飛んできたら、最初にfushihara.org anythingでマッチして、その後@fushihara.org [catchAllする任意のユーザー名]にマッチして、宛先が[catchAllする任意のユーザー名]@fushihara.orgになる。
/etc/postfix/vmailbox にその後処理が通って [catchAllする任意のユーザー名]@fushihara.orgは、catch-all/Maildir/に保存されるって感じかな。順番に考えれば分かり易い？
