      aliases - aliases file for sendmail




      This file describes user ID aliases used by /usr/sbin/sendmail.  The file
      resides in /etc and is formatted as a series of lines of the form
            name: name_1, name_2, name_3, . . .
      The name is the name to alias, and the name_n are the aliases for that
      name.  Lines beginning with white space are continuation lines.  Lines
      beginning with ‘#’ are comments.
      Aliasing occurs only on local names.  Loops can not occur, since no mes‐
      sage will be sent to any person more than once.
      After aliasing has been done, local and valid recipients who have a
      “.forward” file in their home directory have messages forwarded to the
      list of users defined in that file.
      This is only the raw data file; the actual aliasing information is placed
      into a binary format in the file /etc/aliases.db using the program
      newaliases(1).  A newaliases command should be executed each time the
      aliases file is changed for the change to take effect.

      SENDMAIL Installation and Operation Guide.
      SENDMAIL An Internetwork Mail Router.


      If you have compiled sendmail with DBM support instead of NEWDB, you may
      have encountered problems in dbm(3) restricting a single alias to about
      1000 bytes of information.  You can get longer aliases by ‘‘chaining’’;
      that is, make the last name in the alias be a dummy name which is a con‐
      tinuation alias.


      The aliases file format appeared in 4.0BSD.


Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
