[Mailman-Users] Using a Remote Mail Server (from SendMail to Exim)

[Thomas at travelhacker.com]

We currently are currently running Mailman and Sendmail on the same 
server.  We would like to switch (mailing lists only) to Exim on another 
server in our office.

What do we need to do to point Mailman to the Exim server while leaving 
Sendmail intact?

Or do we have to totally disable Sendmail on the Mailman server?

Your advice and guidance is appreciated!
