In the sogo inbox from domain-A i got this messages.
Undelivered Mail Returned to Sender
"Mail Delivery System MAILER-DAEMON@domain-A"
connect to domain-B[Public-IP-B]:25: Connection timed out
Soi think its a Problem with NAT in the OPNsense Firewall, not a sogo problem.
The packet goes out on the public interface and cannot go back on the same
interface.

Are there any error messages from the MTA?
Does "telnet IP 25" works?
