When I assign a new password to an email account, the change is accepted but dovecot keeps giving password errors for a long time - maybe forever until I manually restart it. What can I do to make the reload automatic?
Please use "doveadm auth test <user> [<password>]" to test the credentials on the server. Did you change dovecot settings and may have set auth_cache_size? You can check with "doveconf | grep auth_cache". The auth_cache_size should be "0".
