dovecot Digest, Vol 225, Issue 70

[David Matthews]

hi Christian

Same user and password on both machines, users with shell accounts; exactly the same; in fact I'm struggling to see anything different that might be relevant. On one machine dovecot just works on the other, it stopped working after a dist-upgrade.

One machine (where it works) is a debian 11 VPS, the other is real PC hardware running devuan 4, but their dovecot is a debian package. I can't see why either of that should matter and dovecot also just worked on the PC with devuan 3.

I've tried purging dovecot-core and dovecot-imapd and reinstalling to no effect.
