Can anyone describe an architecture which can handle 1000 IMAP or POP messages per second? Ideally, it would be hosted in the cloud and additional instances could be launched to handle additional load.
The Courier IMAP server is a fast, scalable, enterprise IMAP server that uses Maildirs. Many E-mail service providers use the Courier IMAP server to easy handle hundreds of thousands of mail accounts. With its built-in IMAP and POP3 aggregation proxy, the Courier IMAP server has practically infinite horizontal scalability.
Courier-imap is ok, I used to use it - but dovecot whips it up one side and down another - always has, but since about 1.1, it has become rock-solid, and is so much faster (and lighter on system resources) than courier that I don't understand why anyone still uses it (courier).
