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, 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
``.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.

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
