Look in /usr/ports/mail. You'll find imap-uw and courier, but not Cyrus. 
Cyrus and UW are covered in the O'Reilly IMAP book, if that's of 
interest. Courier is for maildir-format mailboxes only (qmail, 
optionally postfix, maybe others. Not sendmail.)

UW is a breeze to install and use, but isn't particularly fast or 
configurable. For small sites it's fine, but tends to bog down on 
enormous mailboxes of the sort senior management especially seem to 
generate.

I've not delved into the UW code but I think the consensus is that it's 
not great. Also it uses the system password file, which is a bit of a 
disaster waiting to happen.

I've only used courier for a little while, but it looked good. maildir 
is a good thing, and courier supports nice IMAP features like proper 
folders (e.g. a folder can contain both mails and other folders.) If you 
use maildir anyway it's a fair choice.

HTH,
