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 have uninstalled cyrus-imapd and installed dovecot instead.  This actually 
works.  dovecot is even happy to use a Let's Encrypt cert for SSL.

I use postfix + dovecot since forever. I recently switched from 
amavisd-new to maia. It probably is same simple on Linux as it is on 
FreeBSD - I have servers under FreeBSD (or rather multiple jails on 
FreeBSD box).

Good luck!

So it's not that postfix + procmail + cyrus doesn't work, but that you
have a requirement that cyrus can't fulfill.

Just a bit of correction. Pine (which is so old, alpine replaced it) or 
alpine you can configure to talk through IMAP protocol, then it will not 
matter what sort of IMAP server do you have. Just minor correction.

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.

of course, what else do you expect?
(SSL is not the problem, as I'm using cyrus-imapd with SSL)
