+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. For details on how a file is
+              written see the sections "EXTERNAL FILE DELIVERY" and  "DELIVERY
+              RIGHTS"  in the local(8) documentation.  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.  For  details on how a command is executed see "EXTERNAL
+              COMMAND DELIVERY" and "DELIVERY RIGHTS" in the local(8) documen-
+              tation.
+
+              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.
