It depends which version of sendmail you're running. 8.9.x have relaying
disabled by default, so if you're being allowed to relay through your
box look for one or more FEATURE lines containing 'relay' in the
sendmail.mc file, or hosts set as being allowed to relay in your access
database.

Earlier versions allowed relaying by default and had to be set up to
prevent it through one of the anti-spam hacks. If you're running one of
those versions it's really much easier to upgrade to 8.9.x than to
fiddle with it.

Drop me a line if you'd like to see a copy of my sendmail config. I
generate my own through m4 BTW, having told YaST not to touch it.
