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.
