I am having trouble with a SBS 2003 R2 Exhange config.
Some email is being rejected from diffrent isp. I am also testing from diffrent ISP.
Telnet session from ISP 1 (fig1) is blank.
From the Second one i can connect (telnet) and also recive email.
The 3rd ISP fig3 cannot connect to server.
Mij MX record is pointing to 18.104.22.168
I tought using my ISP dropmail mail server but even this is not working.
