Hello
Did the password hash algorithm change between devuan 3 and 4? You can check that in your /etc/shadow file. The start of the password field should be the same something like $6$...
Kind regards, Christian Mack

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.

Hello
passdb { driver = pam }
Is user fred defined on your development machine? Does the password match the one from the production machine?
Kind regards, Christian Mack
