NAME

       masqmail.aliases - masqmail alias file format


DESCRIPTION

       This man page describes the format of the masqmail alias file.  It's
       usual location is /etc/aliases.

       There exists also a variant of this format for glob patterns.  It's
       used with the globalias_file config option.

       The difference between the two formats are only on the left-hand side.
       A normal alias file has a local_part there that gets string-compared
       against the local part; whereas a glob alias file has a glob pattern
       that is matched against the whole address. The right-hand side of the
       two aliasing kinds has the same format.


FILE FORMAT

       Normal alias files consist of lines of the form:

              local_part: item1, item2, ...

       Glob-pattern alias files consist of lines of the form:

              glob_pattern: item1, item2, ...

       Items can be surrounded by double quotes `"'.  If within the quotes
       other quotes are needed for an address they can be escaped with a
       leading backslash `\'.

       A leading backslash `\' indicates that this address shall not be
       further expanded.

       A leading pipe symbol `|' indicates that the item shall be treated as a
       pipe command.  The content of the message will then be sent to the
       standard input of the command.  The command will run under the user id
       and group id masqmail is running as.  If quotes are needed, the pipe
       symbol must appear within the quotes.

       Loops will be detected, the offending address will be ignored.

       Aliases will be expanded at delivery time.  This means that if there is
       a message still in the queue and you change any alias which matches one
       of the recipient addresses, the change will have effect next time a
       delivery is attemped.

       There is no need to restart masqmail or run any command when the alias
       file has been changed. (`masqmail -bi' is a no-op.)


EXAMPLE

       A normal alias file:

              # postmaster is required by RFC 2821
              postmaster: root

              # forward abuse mail to another address
              abuse: abuse@example.org

              # copy root's mail also to meillo
              root: \root, meillo

              # pass mail to a script
              foo: |/usr/bin/foo

       A glob-pattern alias file:

              # the postmaster for any domain on this host
              postmaster@*: ken

              # split virtual domains
              info@foo.example.org: doug
              info@bar.example.org: rob

              # the order of entries is important
              # this must be before the catch-all line
              list-*@example.org: |/path/to/some/script

              # catch-all address forwarded to extern
              *@example.org: brian@other.host.net
