aliases - aliases file for sendmail
This file describes user id aliases used by /usr/lib/sendmail. It 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 files /usr/lib/aliases.dir and
/usr/lib/aliases.pag 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.
Because of restrictions in dbm(3X) a single alias cannot contain more
than 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.
