Thanks. I asked the same question in comp.mail.sendmail and got a reference to
http://anfi.homeunix.net/sendmail/smarttab.html
as a way of routing messages based on sender in sendmail.
However after some further discussion with colleagues we decided not to implement any of this at the moment. Main justification is that a large chunk of our user community has their mail delivered to an Exchange server and the Exchange admins say that there's no way for them to force delivery there.
We'll probably revisit this in the future and look at moving to Exim (since we want to do that anyway).
