Hi orangescape,
Check if you've got the ACCESS_DB feature of Sendmail turned on.
This would probably be defined in your sendmail.cf / sendmail.mc files

Look in /etc/mail
You will probably see a file called "access".  Edit this file, it's what controls relaying in Sendmail.
The article http://www.sendmail.org/tips/relaying.html explains what needs to be set up.

Does that help?
