To set up the database, create a text file /etc/mail/access with lines of one of the following forms:
user@ disposition user@host disposition domainname disposition ###.### dispositionThe first form will match on the username portion of the sender address. The second form will match all mail from a specific user@host. The third form will match all mail from any host in domainname. The fourth form will match any host inside a dotted-decimal numeric IP network (see example below).
The left hand side of each entry can optionally be prefixed with one of the tags To:, From:, or Connect:. Entries marked this way will match only envelope recipients, envelope senders, or the client host address, respectively. Entries which are not marked with one of these tags will match messages on any of the envelope recipients, envelope sender, or client host address.
The disposition should be one of the following:
From:ME_TOO@aol.com REJECT LUSER@ REJECT Connect:spam-king.com ERROR:5.0.0:550 We dont accept Spam Connect:goodhost.spam-king.com OK From:128.174 RELAY bad-domain.com REJECTThis will reject mail from ME_TOO@aol.com, but allow mail to be sent to ME_TOO@aol.com. All messages with an envelope sender or envelope recipient whose username matches LUSER will be rejected. No hosts in the domain spam-king.com except for goodhost.spam-king.com will be allowed to connect. All hosts in the 128.174.*.* IP address range will be allowed to send outgoing mail through us, but we won't relay outside mail back to them. And lastly, all connections will be denied from bad-domain.com, and all messages with an envelope sender or envelope recipient address from bad-domain.com will be rejected.
