aliases - Contains alias definitions for the sendmail program
By default, the aliases file contains the required aliases
for the sendmail program. Do not delete these defaults
because they are needed by the system. This file describes
user ID aliases used by the sendmail command. It is formatted
as a series of lines in the form: name:name_1,
The name is the name that needs an alias, and the name_n
are the aliases for that name. Lines beginning with white
space are continuation lines. Lines beginning with a #
(number sign) are comments.
You can define an alias only on local names. Duplicate
addresses are removed and no message is sent to any person
more than once. For example, if name_1 defines an alias
that is name_2 and name_2 defines an alias that is name_1,
sendmail does not send the same message back and forth.
Local and valid recipients who have a 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 information
that defines the aliases is placed into a binary format in
the files /var/adm/sendmail/aliases.dir and /var/adm/sendmail/aliases.pag
using the newaliases command. For the
change to take effect, the newaliases command must be executed
each time the aliases file is changed.
The sendmail program also supports sending messages to
programs or appending a message to a file. See the sendmail(8) reference page for further information.
Special Aliases [Toc] [Back]
Directs error messages that occur when sending to aliasname
back to address.
Aliases for sendmail use the dbm(3) database format for
faster lookups. A single alias cannot exceed 1,000 characters.
To work around this restriction, you can chain
together aliases. For example:
alias-list: ali1, ali2, ali3 ali1: name 1, name 2 ...
ali2: name n, name n + 1
