Hello. I have a problem with new install of efa. Install it, make init (wiki how to)
I use efa and exchange 2016.
I try to send email from outside, and receive Undelivered Mail Returned to Sender <dmitry@domain.ru>: mail for [192.168.0.220] loops back to myself
0.220 - my exchange server
DNS Recursion : ENABLED

fix it

I tried to use the same ehlo on efa and exchange - i make it different, and it works
Is it possible to use same ehlo fqdn?
