Anthony;

There's a setting in /etc/sendmail.cf for a file containing a list of
systems allowed to relay mail through the server. The setting on my system
is

    FR-o /etc/mail/relay-domains

This is on Redhat 7.0; as I recall, Solaris uses a different filename, and
presumably many other platforms do too. Check the sendmail.cf file to
verify what your server uses.

I believe if you put "foo.com" in this file, sendmail will then allow 
relaying for any host in the foo.com domain. Also, you can put in specific
IP addresses, so if you have a static IP address at your ISP, you can
permit relaying from your dialup machine.

Of course, sendmail won't reread the file until you send it a HUP signal
or restart it:

    kill -HUP <process-id>
