It's really pretty easy.  Look at 'mailertable'.  You can set mail
to any domain you wish to go through any SMTP server you are
permitted to use.  Some places won't accept my mail as even though
I"m on a STATIC IP and have been the same one for 3 years, they
consider all DSL lines as spam sources.  So depending on end
destination I send some to my providers transport, and others off
to another machine I manage.

Setup is simple.

abc.com		smtp:<mail.somedomain.net>

And then just run make in /etc/mail to compile it.

Sendmail is very flexible.
