Using a .forward to send mail to multiple accounts

Submitted by sandip on Thu, 05/06/2010 - 14:00.

If you put multiple addresses in a .forward file, a copy will be sent to each.

remoteuser1@domain.tld, remoteuser2@domain.tld, remoteuser3@domain.tld

If you want to keep a copy of each message in the original account without causing a .forward infinite loop, put a backslash in front of the account name.

\localuser, remoteuser1@domain.tld, remoteuser2@domain.tld, remoteuser3@domain.tld

sendmail access.db by example

Submitted by sandip on Wed, 02/06/2008 - 00:02.

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!!

# by default we allow relaying from localhost...
localhost.localdomain           RELAY
localhost                       RELAY
127.0.0.1                       RELAY

# Allow Connect from local server IPs
