We run a mailing list for users of Project Cyrus software. The info-cyrus@andrew.cmu.edu mailing list exists for the discussion of this server and other Cyrus software. Please do NOT send subscription requests to the list.
To subscribe: Send mail to info-cyrus-subscribe@lists.andrew.cmu.edu to subscribe (or just click the link above and that should just work).
An archive is available via anonymous IMAP at imap://cyrus.andrew.cmu.edu/archive.info-cyrus.
A web archive is also available at http://www.cyrusimap.org/mediawiki/index.php/Cyrus_Mailing_Lists#Archives
If you are not subscribed to the list (or you are sending the message from a different address than the one which you are subscribed under), your message is directed to a human for approval. Unfortunately, the human does not always promptly process the message.
There is also a developers list available at cyrus-devel@lists.andrew.cmu.edu. with similar subscription methods and archive location
