NAME
       aliases - aliases file for sendmail

SYNOPSIS
       aliases

DESCRIPTION
       This file describes user ID aliases used by sendmail.  The
       file resides in /etc/mail and is formatted as a series  of
       lines of the form

	      name: addr_1, addr_2, addr_3, . . .

       The  name  is  the  name  to alias, and the addr_n are the
       aliases for that name.  addr_n can  be  another	alias,	a
       local  username,  a  local filename, a command, an include
       file, or an external address.

       Local Username
	      username

	      The username must be available via getpwnam(3).

       Local Filename
	      /path/name

	      Messages are appended to the file specified by  the
	      full pathname (starting with a slash (/))

       Command
	      |command

	      A  command  starts  with	a  pipe  symbol  (|),  it
	      receives messages via standard input.

       Include File
	      :include: /path/name

	      The aliases in pathname are added  to  the  aliases
	      for name.

       E-Mail Address
	      user@domain

	      An e-mail address in RFC 822 format.

       Lines  beginning  with white space are continuation lines.
       Another way to continue lines is by  placing  a	backslash
       directly  before  a  newline.   Lines beginning with # are
       comments.

       Aliasing occurs only on local names.  Loops can not occur,
       since  no  message  will  be  sent to any person more than
       once.

ALIASES(5)					       ALIASES(5)

       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 infor­
       mation  is  placed  into  a  binary  format  in	the  file
       /etc/mail/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 An Internetwork Mail Router.

BUGS
       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 informa­
       tion.  You can get longer aliases  by  ``chaining'';  that
       is,  make the last name in the alias be a dummy name which
       is a continuation alias.

HISTORY
       The aliases file format appeared in 4.0BSD.
