Problems with DNS - "Server name must resolve"

This might not be a problem with your DNS setup but with your 
(possible) sendmail setup.

The SuSE people changed at least some parts of their sendmail (anti
spam) 
rule sets for 6.1 - I had to edit /etc/mail/access according to my
setup.

Until I figured this out, sendmail complained with:
"Sender domain must resolve".

Hope this helps.
