There was a discussion on the postfix-users mailing list about doing
this sort of thing on a fairly tight budget recently.  It's not the same
MTA, but the same principles apply.

You should be able to get sendmail to send copies of all the messages
sent to one server to the other (ie, they both end up doing local
delivery) but you then run into a lot of problems keeping track of what
happens when users do things like change config or delete mail.  You
need changes to propagate very quickly or people will start to notice.

Why do you need to send it off again?

Not a thing.

You'd be much better off asking about this stuff somewhere like
comp.mail.sendmail - it's fairly specialized stuff that is often
attacked with funky hardware.
