here is a simple (and *dirty*) method, but it sort of works for
light-duty machines: example on how i approximately did a few
switchings from smail to exim, once-upon-a-time:

1) to make sure that no mails are in the queue anymore:

   $ runq
   $ mailq

2) disallow smtp connection:

   <plug out the cable :>

3) force remove the old MTA:

   $ dpkg --purge --force-depends smail

4) install the new one:

   $ dpkg --install exim_*.deb 

5) allow smtp connections 

   <plug in the cable :>

6) tune some software if needed (listmanagers, etc).

...and there you have it.  beware, it's quite a *dirty* method! :-))
