SMTPAUTH(5)

NAME
smtpauth - greylist file for postoffice

SYNOPSIS
/var/db/smtpauth.db

DESCRIPTION
This file records client access to the postoffice SMTP server. It contains records that either have the address given in the SMTP ‘MAIL FROM:’ command, or the username from the SMTP ‘MAIL FROM:’ and the IP address that the mail connected from. In both cases, this address is followed by two dates (in UNIX time_t format) which are, in order, the time when postoffice will accept mail from this user, and the time when the last connection was made.

This file is a @NDBM@(3) database and is not human readable; the authexpire(8) program is used to maintain it and remove old records.

The record format used in this database is:
ADDRESS
    Either the SMTP ‘MAIL FROM:’ address or the username from that address, followed by the IP address of the connecting machine (quoted with ‘[]’)
DATE DATE
    When the client can connect and when the client last connected (both in seconds after the epoch). If the client is blacklisted (via the -b flag in authexpire(8) ), the first DATE will be the magic token *.
