It's quite easy to distribute data to several servers with MySQL - either
have the slave servers consult a central database (or cluster) directly, or
replicate the database around all the servers. The replication feature in
MySQL is very robust, we've been using it for several years.

Courier IMAP is simple to implement, and gives you flexible authentication
(LDAP, MySQL etc). If you're ever going to need IMAP, I'd suggest go
straight for Courier - use it for POP3 to begin with, and IMAP is there for
free when you need it.

So can Exim. Many discussions here on the subject, but several million
mailboxes is not unusual. You'll need to plan your hardware accordingly if
you want to scale that big, of course.
