Just FYI, I was talking multiple SMTP servers not IMAP servers. If I did it, I would have 2 public facing SMTP servers which would then route to an internal SMTP server probably with a single IMAP server. The routing would probably be over a private link not a public one and the final server would present only IMAP publically. Really reduces attack surface.
