Hello everyone.
I am serving 2 Zimbra mail servers on Ubuntu.
Both have a 220 double response issue on smtp session.
A colleague using Zimbra on CentOS has no such problem.
What is the reason?
I can’t repeat it myself via telnet
Some testers think that I have open relay, but this is not the case and this can be seen in WireShark
Double respone with code 220 from smtp

We really need to see unobfuscated log file snippets detailing the error, and the output of zmcontrol -v to be able to help.
All the best,
Mark

Re: Double respone with code 220 from smtp
zimbra@mail:~$ zmcontrol -v
Release 8.8.15.GA.3869.UBUNTU18.64 UBUNTU18_64 FOSS edition, Patch 8.8.15_P27.
version indicated above.
But I did not quite understand what kind of log we are talking about. Where and how to find it?

Typically errors are found in zimbra.log (MTA/system) and mailbox.log (mailbox service).
