No actually the problem is cyrus-imapd: cyrus-imapd expects all users to use imap (or pop3) to access their E-Mail. It does not allow for other E-Mail methodologies, including using local UNIX utilies (eg mail or pine or mh or other tools like QWK).

I suppose it shouldn't be a huge surprise that an IMAP server expects you to use IMAP. The backend uses its own files in a manner that is optimised for running IMAP, which improves performance and load on the server.

If you're using dovecot, at least try to avoid using mbox format, due to how terrible it is for performance.
