1.TH ALIASES 5 "15 January 1983"
2.SH NAME
3aliases \- aliases file for sendmail
4.SH SYNOPSIS
5.B /usr/lib/aliases
6.SH DESCRIPTION
7This file describes user id aliases used by
8.I /usr/lib/sendmail.
9It is formatted as a series of lines of the form
10.in +0.5i
11name: name_1, name2, name_3, . . .
12.in
13The
14.I name
15is the name to alias, and the
16.I name_n
17are the aliases for that name.
18Lines beginning with white space are continuation lines.
19Lines beginning with `\|#\|' are comments.
20.PP
21Aliasing occurs only on local names.
22Loops can not occur, since no message will be sent to any person more than once.
23.LP
24After aliasing has been done, local and valid recipients who have a
25``.forward'' file in their home directory have messages forwarded to the
26list of users defined in that file.
27.PP
28This is only the raw data file; the actual aliasing information is
29placed into a binary format in the files
30.I /usr/lib/aliases.dir
31and
32.I /usr/lib/aliases.pag
33using the program
34.IR newaliases (1).
35A
36.I newaliases
37command should be executed each time the aliases file is changed for the
38change to take effect.

43.br
44SENDMAIL An Internetwork Mail Router.
45.SH BUGS
46Because of restrictions in
47.IR dbm (3)
48a single alias cannot contain more than about 1000 bytes of information.
49You can get longer aliases by ``chaining''; that is, make the last name in
50the alias be a dummy name which is a continuation alias.
