SirAdmin - a GUI replacement for cyradmin

Once again, AFP548 have posted a link to another very useful sysadmin utility for Mac OS X - SirAdmin

From the linked page:

 

"SirAdmin is essentially a GUI replacement for cyradm, in that it allows you to locally or remotely administer your Cyrus IMAP server. I've tested it against the Cyrus server from Mac OS X Server 10.3 and 10.4, as well as Cyrus running on RedHat."
