Courier -vs- Dovecot

Courier has been the default IMAP server for many years. However, vpopmail support has always been a second class citizen to most of the courier developers. It has also been a persistent nuisance to keep working reliably due to frequent changes. However, it works well, scales well, and is still a supported feature of Mail Toaster.

Then came Dovecot. It has been an extremely dependable POP3/IMAP server. It also builds much, much faster than Courier. I highly recommend Dovecot.

There are some known Migrating to Dovecot that should be reviewed prior to switching.
