NAME
       aliases - aliases file for sendmail

SYNOPSIS
       /usr/lib/aliases

DESCRIPTION
       This  file  describes user id aliases used by _/_u_s_r_/_l_i_b_/_s_e_n_d_m_a_i_l_.  It is
       formatted as a series of lines of the form
            name: name_1, name2, name_3, . . .
       The _n_a_m_e is the name to alias, and the _n_a_m_e__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  _/_u_s_r_/_l_i_b_/_a_l_i_a_s_e_s_._d_i_r  and
       _/_u_s_r_/_l_i_b_/_a_l_i_a_s_e_s_._p_a_g  using  the  program  _n_e_w_a_l_i_a_s_e_s(1).  A _n_e_w_a_l_i_a_s_e_s
       command should be executed each time the aliases file  is  changed  for
       the change to take effect.

BUGS
       Because  of  restrictions in _d_b_m(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.
