NAME

       table_passwd — format description for smtpd passwd tables

DESCRIPTION

       This manual page documents the file format of "passwd" tables used by the smtpd(8) mail daemon.

       The format described here applies to tables as defined in smtpd.conf(5).

PASSWD TABLE

       A  "passwd"  table  stores  information  regarding  local  users.   The  information is encoded using the
       traditional passwd(5) format and allows  the  sharing  of  a  user  database  across  different  software
       supporting this format.

       The table is used by smtpd(8) when authenticating a user or when user information such as user-id or home
       directory is required for a delivery.

       A  "passwd" table consists of a flat file containing the user entries, each one on a line by itself, with
       fields separated by a colon:

             gilles:*:1000:1000:Gilles:/home/gilles:/sbin/nologin
             eric:*:1001:1001:Eric:/home/eric:/sbin/nologin
             chl:*:1002:1002:Charles:/home/chl:/sbin/nologin

       If the table is used for authentication, the second field may contain  a  password  encrypted  using  the
       crypt(3)  function.   Such  passwords can be generated using the encrypt(1) utility or smtpctl(8) encrypt
       command.
