Well....their is an option in mailertable to NOT rely
on MX to deliver the messages as I showed in my first
email.
.somedomain.com	relay:[mail.someotherdomain.com]
(the brackets tell sendmail to not use MX lookups)

Also, haha, forgot to tell you but are you running the
following after you edit the file:
makemap hash /etc/mail/mailertable <
/etc/mail/mailertable
??
This will create the hash db that stores all this
stuff for sendmail...

So, now that we are all confused....do the following:
1) put the following in /etc/mail/mailertable:
.somedomain.com	smtp:[mail.someotherdomain.com]
2) makemap hash /etc/mail/mailertable <
/etc/mail/mailertable
3) restart sendmail
4) Make sure you do NOT have the domain listed in the
Cw config file.  (For me that is
/etc/mail/local-host-names)
5) Make sure you DO have the domain listed in the
relay domains file (For me that is
/etc/mail/relay-domains)
6) Restart sendamil
7) Sendmail an email to recipient at someotherdomain.com

Good luck!
