Zimbra 7.1.2 and the MTA seems to be deferring e-mail when it is received.
Oct 1 09:35:42 www postfix/error: 5FB8C1A803EE: to=<firstname.lastname@example.org>, relay=none, delay=0.15, delays=0.08/0.01/0/0.06, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to thedigiologygroup.org[184.108.40.206]:7025: Connection timed out)
I can telnet to both 25 and 7025.
I do get a
$ telnet thedigiologygroup.org 25 Trying 220.127.116.11... Connected to thedigiologygroup.org. Escape character is '^]'. 220 thedigiologygroup.org ESMTP Postfix 500 5.5.2 Error: bad syntax 500 5.5.2 Error: bad syntax`
I dont see email in the inbox obviously and I am not sure how to troubleshoot what is going on.
Nothing DNS has changed.
This box has been running for a year
Zimbra was removed and re-installed after trying to upgrade to ZCS-8 with no luck.
