I have an older EXchange server 5.5.
The ehlo message sent from that server, is the Exchange server's FQDN. The official internet domaine for that domainename no longer belongs to the company. So now i cannot send to hotmail.com and others
How can I Change the ehlo message to a current MX record that points to my server?
EX: my Ehlo message from that server is srv01.xxx.dk, and i want it to say srv01.yyy.dk
