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.
