• Try dovecot, I use that personally.

  There also appears to be good documentation for dovecot+procmail as well
  – https://wiki.dovecot.org/procmail

• I use dovecot with postfix and procmail; works fine.

• the problem seems to be procmail, I use postfix and cyrus-imapd with no problems;

• I suggest dovecot if you don’t want to deal with Cyrus IMAP, but I can tell you from first-hand experience that you used to be able to use procmail to deliver to Cyrus IMAP, using ‘deliver’.

  However, if you get postfix to deliver directly via lmtp, you can take advantage of SIEVE to filter your mail, which is quite powerful. (I
  miss it, work migrated to Google Apps and its filters are subpar.)

  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)
