Yes, I can relate to this problem. In the sendmail FAQ, it says
that there's an immediate solution, unless you want to reconfigure
sendmail cf files: /etc/mail/relay-domains and /etc/mail/access.
Just put domains you want to relay in the first or/and the second.
Cobalt use the second one. But the weird thing is: sometimes it works
, some times it don't (tested it with a different ISP connection).

Hope it helps
