Hi,

I am experiencing similar error messages when setting passdb to mechanisms = plain login.

More details can be found at https://github.com/orgs/docker-mailserver/discussions/3836.

I hope this information helps.

Regards,

James

Hi there,

I'm experiencing the following when I replicate mails between two host, using different versions of dovecot:

*Host A                             Host B result* dovecot-2.3-19     -->      dovecort-2.3.16      ERROR: auth: Error: All password databases were skipped. doveadm(10.0.0.1,oliver.krone@snoog.ch): Error: auth-master: passdb lookup(oliver.krone@snoog.ch): Auth PASS lookup failed mail  | 2024-07-04T14:21:35.635047+00:00 mail dovecot: doveadm(10.0.0.1,oliver.krone@snoog.ch): Error: /run/dovecot/auth-userdb: passdb lookup failed (to see if user is proxied, because doveadm_port is set)

dovecot-2.3-21   -->        dovecort-2.3.16       no errors, working

Basically it does work with 2.3-21 --> 2.3-16 and it does not work with 2.3-19 --->  2.3-16  without any changes in the configuration files.

Any ideas?

Thank you very much.

Best regards Oliver
