Zimbra 8.8.6, latest patch
Mail to root on the server is getting bounced, with the following message:
Feb 10 05:40:07 aeon postfix/smtp[15794]: 84E522660E6B: to=<root@aeon.pshift.de>, relay=none, delay=0.1, delays=0.1/0/0/0, dsn=5.4.6, status=bounced (mail for aeon.pshift.de loops back to myself)
What am I missing in my config to make this work?
