aliases - aliases file for sendmail
1mSYNOPSIS0m
1maliases0m
1mDESCRIPTION0m
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 4mname24m is the name to alias, and the 4maddr_n24m are the aliases for that
name. 4maddr_n24m can be another alias, a local username, a local filename,
a command, an include file, or an external address.
1mLocal Username0m
username
The username must be available via getpwnam(3).
1mLocal Filename0m
/path/name
Messages are appended to the file specified by the full pathname
(starting with a slash (/))
1mCommand0m
|command
A command starts with a pipe symbol (|), it receives messages
via standard input.
1mInclude File0m
:include: /path/name
The aliases in pathname are added to the aliases for 4mname.0m
1mE-Mail Address0m
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.
If an alias is found for 4mname24m, sendmail then checks for an alias for
4mowner-name24m. If it is found and the result of the lookup expands to a
single address, the envelope sender address of the message is rewritten
to that address. If it is found and the result expands to more than
one address, the envelope sender address is changed to 4mowner-name24m.
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/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.

1mBUGS0m
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.
1mHISTORY0m
The 1maliases 22mfile format appeared in 4.0BSD.
