That’s odd, never had a Dovecot not wanting to talk to Zammad (yet).
Do you happen to have E-Mails in the affected mailbox?
If so, could you check if you can solve this issue by temporary moving all mails away from your mailbox?
Possibly this is an issue with an existing mail that Zammad can’t import or the fetching process dies during that process in general.
The reason for this error message could be a special character in the password of your imap mailbox. Change the password and try not to use special characters.
That’s the solution. So i switched to just Numbers and Characters and just made the password longer.
It would be nice, if the wizzard gives a warning, if you input special characters or fix it.
Thank you very much.
Just a small follow up on this:
We’re currently investigating and discussing this topic internally.
Eventually we’ll create an issue to address this later on, but that’s not a fixed topic yet.
Personally I see the following special characters as best practise for passwords:
!"#$%&'()*+,-./:;<=>?@[\]^_{|}~`
Thanks for your time, I’ll update this thread if I have further information!
