sendmail: Relay access denied

Applies to

SuSE Linux: Version 6.1

Symptom:

Sendmail generates the message: 'Relay access denied'.

Reason:

SuSE Linux 6.1 comes with Sendmail version 8.9.3. As a default, this version does not allow the mail server to be misused as a mail relay. Open mail relay servers allow spammers to send mail to others, through your computer!

Solution:

To allow your own server to relay mail for your own domain, you have to modify the file /etc/mail/access:

For example:

my1dom.com	RELAY
my2dom.com	RELAY
Afterwards do not forget to run the command SuSEconfig and rcsendmail restart. You can also configure the file /etc/mail/relay-domains with your internal network, for example:
192.168.0
192.168.1

For the two Class C Networks 192.168.0.0/24 and 192.168.1.0/42.

There is more detailed information on this subject in the file: /usr/share/sendmail/README.
