My Exchange 2K server is on my private network and has a private domain name "exsvr.a.com" with a private IP address 192.168.10.1, and I am using the firewall to port forward the email traffic from a public IP (with our public email domain name "mail.aaaa.com") to the Exchange sever.
Recently, lots of our outgoing emails were bounced back , the reason is because our email hostname show a private name " exsvr.a.com" when it talks to other email server.
so it got treated as a spam source.
Please advice how could I solve this problem.
thank you so much
