How to remove a double smtp banner postfix forwarder'and pfsense is also?

Postfix forwarder on pfsense is also for some unclear to me reason, shows the smtp banner 2 times, the first(wrong), and after 5 seconds the second. If you specify manually in the "custom options", then in a short period of time all normalize, but then again double banner. What could be the reason and how to fix it? Thank you
