Hi, after the last ispconfig update i also changed the password of a mail account. Thunderbird errored in connecting and i updated to the new one and mails could be sent and received again. All good but then the next morning i couldn't send emails with that account, rest works. systemctl status dovecot listed some login errors. Restarting dovecot the problem is gone and i can send emails again. ca. 24h later the next morning same problem. I think i had the same problem before now that i write this down here, going to search through my previous postings. Any ideas why this happens?
