SuSE 9.1 Sendmail

[Ron Kinney]

I am, by no means, an sendmail expert, so bear with me. I am currently trying to get an email server running on my SuSE Linux machine, but keep running into an issue. All mail goes out ok, but any incoming mail seems to give me errors.

Lets say that Server B(user@serverb.com) is the email server I am trying to configure. If I send an email to serverb from another PC(user@servera.com), the message bounces back with the following error :

Your message did not reach some or all of the intended recipients.

Subject: yellow
Sent: 8/26/2004 1:48 PM

The following recipient(s) could not be reached:

user@serverb.org on 8/26/2004 7:53 AM
A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients. Contact your administrator.
< linux.site #5.3.5 SMTP; 553 5.3.5 system config error>

However, root@serverb.com gets the following message in his box :

Any ideas?

Found the issue. In /etc/sendmail.cf, I needed to add the following line :
