Someone tell me the Cyrus imap is better than Courier-imap (Please don't troll) because (this is what I understand but I never use it) it's easy to split physicaly the smtp (with anti-virus/anti-spam/etc...) server and the imap server. And between the smtp server and the imap server we can use LSMTP (L for Ligth) protocol. The difference between LSMTP and SMTP is the first is very light and more faster than SMTP.
Yes, Cyrus has a rep for scaling well in large installations although it also has a reputation for being hard to configure. Courier also scales very well though and can easily be spread across numerous boxes with one handling SMTP and one handling IMAP, you can even do multiple boxes per service. The best way to acheive this is probably via a NFS share common to the SMTP and IMAP servers. The SMTP server will write new mail to the Maildirs stored on the NFS Server and the IMAP server will read/write the mail as users access it. Maildir, Courier's backend storage method is quite capable over NFS and is designed to prevent corruption.
