Last month I migrate my Univention Zarafa to Kopano,
Overall it works fine, some users have a zpush issue, but the server itself works as expected.
But now after the server reboot, we don’t receive any new mail.
I’m me not aware that we change any setting.
But the mail.log show me the following:
relay=none, delay=21486, delays=21486/0.04/0/0, dsn=4.4.1, status=deferred (connect to 127.0.0.1[127.0.0.1]:10024: Connection refused)
Hopefully one of you can tell me how I can solve this issue!
