NAME

       aliases - aliases file for sendmail

SYNOPSIS

       /etc/aliases

DESCRIPTION

       This file describes user id aliases used by /usr/sbin/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 /etc/aliases.dir and
       /etc/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.

BUGS

       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.

NAME

       aliases - Contains alias definitions for the sendmail program

SYNOPSIS

       /var/adm/sendmail/aliases

DESCRIPTION

       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, name_2, name_3,..

       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 .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 information that defines the aliases is placed into a binary format in the files /var/adm/send-
       mail/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
       Directs error messages that occur when sending to aliasname back to address.

RESTRICTIONS

       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
