sendmail access.db by example

Wed, 02/06/2008 - 00:02 — sandip

The sendmail access database file can be created to accept or reject mail from selected domains.

Since "/etc/mail/access" is a database, after creating the text file, use makemap to create the database map.

# makemap hash /etc/mail/access.db < /etc/mail/access

Below is what my access file currently looks like and can be used as a starting point. All internal addresses have been changed except for spammers!!
