Name
       aliases - aliases file for sendmail

Description
       The  aliases  file  is  an ASCII file that describes user ID aliases that are used in It is formatted as a series of lines in the following
       form:
       name: name_1, name2, name_3, . . .
       The name is the name to alias, and the name_n are the aliases for that name.  Each is separated from the next by a new line.

       Continuation lines begin with white space.  Comment lines begin with a number sign (#).

       You can only assign aliases to local names.  Loops are not allowed because a message should be sent to a person only once.

       After an alias has been applied, local and valid recipients who have a file in their home directory can have messages forwarded to the list
       of users defined in that file.

       This  is  only the raw data file; the actual information pertaining to aliases is placed into binary format in the files and using the pro-
       gram The command should be executed each time the aliases file changes.	This command allows the new changes to take effect.

Restrictions
       Because of restrictions in a single alias cannot contain more than approximately 1000 bytes of information.  You can specify longer aliases
       by chaining; that is, use a dummy name for the last name in the alias, which creates a continuation alias.

       The  database  may  be distributed in a network by a naming service, such as Yellow Pages or BIND/Hesiod.  See the Guide to Yellow Pages or
       the chapter on Hesiod in the Guide to BIND for setup information.
