     This file describes user ID aliases used by _/_u_s_r_/_s_b_i_n_/_s_e_n_d_m_a_i_l. The file
     resides in _/_e_t_c and 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 mes-
     sage will be sent to any person more than once.

     After aliasing has been done, local and valid recipients who have a
     ``_._f_o_r_w_a_r_d'' 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 _/_e_t_c_/_a_l_i_a_s_e_s_._d_b using the program
     newaliases(1).  A newaliases command should be executed each time the
     aliases file is changed for the change to take effect.

BBUUGGSS
     If you have compiled sendmail with DBM support instead of NEWDB, you may
     have encounter 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 con-
     tinuation alias.
