Hi Martin.  You may also facilitate relaying by adding a RELAY entry to
the access file /etc/mail/access (exact location can vary).  You'll need
to see if you have it setup in sendmail.cf (just grep for access to do
this).

Once edited you update access thusly:

cd /etc/mail
cat access | makemap hash access [1]

[1] You may need to do cat access | makemap dbm access depending on the
format that the data is saved in.

The access file can be updated on the fly (no need to restart sendmail
unlike a change to relay-domains), however the access method is a little
slower than relay-domains so relay-domains is better for a busy mail
server.

This all assumes that your "mc" file is setup in a reasonably standard
way.  You could, for example, allow all relaying by default but that would
be a bad bad idea.

See http://www.sendmail.org for a wealth of useful info on using m4 to
create a sendmail.cf file.
Cheers,
