+ALIASES(5)                                                          ALIASES(5)

+NAME
+       aliases - Postfix local alias database format
+
+SYNOPSIS
+       newaliases
+
+DESCRIPTION
+       The  aliases(5) table provides a system-wide mechanism to redirect mail
+       for local recipients. The redirections are  processed  by  the  Postfix
+       local(8) delivery agent.
+
+       Normally,  the aliases(5) table is specified as a text file that serves
+       as input to the postalias(1) command. The result, an  indexed  file  in
+       dbm  or  db format, is used for fast lookup by the mail system. Execute
+       the command newaliases in order  to  rebuild  the  indexed  file  after
+       changing the Postfix alias database.
+
+       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 expressions. In this case, the
+       lookups are done in a slightly different way as described  below  under
+       "REGULAR EXPRESSION TABLES".
+
+       Users  can  control  delivery  of their own mail by setting up .forward
+       files in their home directory.  Lines in per-user .forward  files  have
+       the same syntax as the right-hand side of aliases(5) entries.
+
+       The format of the alias database input file is as follows:
+
+       o      An alias definition has the form
+
+                   name: value1, value2, ...
+
+       o      Empty  lines and whitespace-only lines are ignored, as are lines
+              whose first non-whitespace character is a `#'.
+
+       o      A logical line starts with  non-whitespace  text.  A  line  that
+              starts with whitespace continues a logical line.
+
+       The  name  is a local address (no domain part).  Use double quotes when
+       the name contains any special characters such as whitespace, `#',  `:',
+       or  `@'.  The  name  is  folded to lowercase, in order to make database
+       lookups case insensitive.
+
+       In addition, when an alias exists for owner-name,  this  will  override
+       the  envelope sender address, so that delivery diagnostics are directed
+       to owner-name, instead of the originator of the message  (for  details,
+       see  owner_request_special,  expand_owner_alias and reset_owner_alias).
+       This is typically used to direct delivery errors to the maintainer of a
+       mailing  list,  who  is  in a better position to deal with mailing list
+       delivery problems than the originator of the undelivered mail.
+
+       The value contains one or more of the following:
+
+       address
+              Mail is forwarded to address, which is compatible with  the  RFC
+              822 standard.
+
+       /file/name
+              Mail  is  appended  to  /file/name.  See local(8) for details of
+              delivery to file.  Delivery is not  limited  to  regular  files.
+              For  example,  to  dispose  of  unwanted  mail,  deflect  it  to
+              /dev/null.
+
+       |command
+              Mail is piped into command. Commands that contain special  char-
+              acters,  such  as  whitespace, should be enclosed between double
+              quotes. See local(8) for details of delivery to command.
+
+              When the command fails, a limited amount of  command  output  is
+              mailed  back  to  the  sender.  The file /usr/include/sysexits.h
+              defines the expected exit status codes. For example, use  "|exit
+              67"  to simulate a "user unknown" error, and "|exit 0" to imple-
+              ment an expensive black hole.
+
+       :include:/file/name
+              Mail is sent to the  destinations  listed  in  the  named  file.
+              Lines  in :include: files have the same syntax as the right-hand
+              side of alias entries.
+
+              A destination can be any destination that is described  in  this
+              manual  page.  However, delivery to "|command" and /file/name is
+              disallowed by default. To enable,  edit  the  allow_mail_to_com-
+              mands and allow_mail_to_files configuration parameters.
+
+ADDRESS EXTENSION
+       When  alias database search fails, and the recipient localpart contains
+       the optional  recipient  delimiter  (e.g.,  user+foo),  the  search  is
+       repeated for the unextended address (e.g., user).
+
+       The   propagate_unmatched_extensions   parameter  controls  whether  an
+       unmatched address extension (+foo) is propagated to the result of table
+       lookup.
+
+CASE FOLDING
+       The local(8) delivery agent always folds the search string to lowercase
+       before database lookup.
+
+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).
+       NOTE: these formats do not use ":" at the end of a pattern.
+
+       Each regular expression is applied to the entire search string. Thus, a
+       search string user+foo is not broken up into user and foo.
+
+       Regular expressions are applied in the order as specified in the table,
+       until a regular expression is found that matches the search string.
+
+       Lookup results are the same as with indexed file lookups.  For security
+       reasons there is no support for $1, $2 etc. substring interpolation.
+
+SECURITY
+       The local(8) delivery agent disallows regular  expression  substitution
+       of $1 etc. in alias_maps, because that would open a security hole.
+
+       The  local(8)  delivery  agent will silently ignore requests to use the
+       proxymap(8) server within alias_maps. Instead it will  open  the  table
+       directly.  Before Postfix version 2.2, the local(8) delivery agent will
+       terminate with a fatal error.
+
+CONFIGURATION PARAMETERS
+       The following main.cf parameters are  especially  relevant.   The  text
+       below  provides  only  a  parameter  summary.  See postconf(5) for more
+       details including examples.
+
+       alias_database (see 'postconf -d' output)
+              The alias databases for local(8) delivery that are updated  with
+              "newaliases" or with "sendmail -bi".
+
+       alias_maps (see 'postconf -d' output)
+              The alias databases that are used for local(8) delivery.
+
+       allow_mail_to_commands (alias, forward)
+              Restrict local(8) mail delivery to external commands.
+
+       allow_mail_to_files (alias, forward)
+              Restrict local(8) mail delivery to external files.
+
+       expand_owner_alias (no)
+              When   delivering   to   an   alias   "aliasname"  that  has  an
+              "owner-aliasname"  companion  alias,  set  the  envelope  sender
+              address to the expansion of the "owner-aliasname" alias.
+
+       propagate_unmatched_extensions (canonical, virtual)
+              What  address  lookup  tables copy an address extension from the
+              lookup key to the lookup result.
+
+       owner_request_special (yes)
+              Enable special  treatment  for  owner-listname  entries  in  the
+              aliases(5)  file,  and  don't  split  owner-listname  and  list-
+              name-request address localparts when the recipient_delimiter  is
+              set to "-".
+
+       recipient_delimiter (empty)
+              The  set of characters that can separate an email address local-
+              part, user name, or a .forward file name from its extension.
+
+       Available in Postfix version 2.3 and later:
+
+       frozen_delivered_to (yes)
+              Update the local(8) delivery agent's idea of  the  Delivered-To:
+              address  (see  prepend_delivered_header) only once, at the start
+              of a delivery attempt; do not update the  Delivered-To:  address
+              while expanding aliases or .forward files.
