Just a note here. Cyrus IMAP server is designed to be run as a *sealed* 
server, i.e. the only people that actually log into that machine are 
systems administrators. The *only* access you have to the e-mail on that 
machine is via the POP and/or IMAP protocols. This comes in handy for 
organizations that want a central, secure e-mail server. We use in in 
conjuntion with postfix & spamassassin for a very effective mail server 
for our small company. Is Cyrus IMAP the way to go for everyone, of 
course not. For us, it provides alot more advantages than disadvantages.

Cyrus is also designed to scale well and provide good performance with a 
larger number of email boxes. As far as security, our remote users 
(those on travel or other locations) simply have a imap client on their 
local machine that can connect via SSL (thunderbird does a good job), 
instead of trying trying to run an interactive SSH session through the 
firewall.

To each their own....

hope this helps give perspective...
