I think you mean 'POP' or 'IMAP' rather than 'SMTP', but yes.

In general, I'd advise against that - that way lies madness.

In particular, users tend to get confused if they have multiple different 
mailbox interfaces.  Plus you then have to maintain two completely independent 
mail services rather than just one (including backups and everything else that 
that entails.)

Usually it's much less effort _in the long run_ to migrate the data.

Cheers,
David
