We found chatting on IRC has just that little more bandwidth available for a conversation as opposed to mailing lists and/or bug reports, so we would like to invite you to join us on IRC if you're interested.
There are often Cyrus developers and experienced administrators hanging around to talk to in a friendly, helpful environment.
