ALIASES (5)
aliases
aliases file for sendmail
SYNOPSIS
DESCRIPTION
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
-filled -offset indent
name: name_1, name2, 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 message will be sent to any person more than once.
After aliasing has been done, local and valid recipients who have a
Pa .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.

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 information.
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
file format appeared in
4.0 .
