ALIASES(5)          UNIX Programmer's Manual           ALIASES(5)



NAME
     aliases - aliases file for delivermail

SYNOPSIS
     /usr/lib/aliases

DESCRIPTION
     This file describes user id aliases that will be used by
     /_e_t_c/_d_e_l_i_v_e_r_m_a_i_l. It is formatted as a series of lines of
     the form
          name:addr1,addr2,...addrn
     The _n_a_m_e is the name to alias, and the _a_d_d_r_i are the
     addresses to send the message to.  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.

     This is only the raw data file; the actual aliasing informa-
     tion is placed into a binary format in the files
     /usr/lib/aliases.dir and /usr/lib/aliases.pag using the pro-
     gram _n_e_w_a_l_i_a_s_e_s(5).  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(3) a single alias cannot con-
     tain more than about 1000 bytes of information.  You can get
     longer aliases by ``chaining''; i.e. make the last name in
     the alias by a dummy name which is a continuation alias.
