ALIASES(5) BSD Programmer's Manual ALIASES(5) NNAAMMEE aalliiaasseess - aliases file for sendmail SSYYNNOOPPSSIISS aalliiaasseess DDEESSCCRRIIPPTTIIOONN 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.
