(Sorry for the dupe. I received a "database error" when posting the first one.)
I recently upgraded from 5.0.21 to 6.0.10 (Open Source).
I noticed a lot of these in the zimbra.log file:
Open relay? Nonlocal recips but not originating: ...
I tested with the Open Relay testers, and the server seems to be OK.
But the messages are still of concern.
Did the customary searches and found this:
[SOLVED] Open Relay amavis warnings in zimbra.log
Not sure if this actually resolves the problem.
Tha amavis list mentioned something about a new warning message with amavisd-new-2.6.4 and settings for "mynetworks" and "originating" ...
(Reference: Old Nabble - Amavis - Open relay, non local recip, mail aliasing and forwarding)
Is there something I missed in the configuration that was either not preserved in the Zimbra upgrade? Is this something new?
Thanks for your time.
