Hi, I am trying to deploy my first Exchange Server and I've hit a brick wall. The server has a static, public IP address. The domain has been set up, *.domain.com, www.domain.com, mail.domain.com and @.domain.com A records are pointing to the servers IP address. The MX record is set to mail.domain.com. with a priority of 10. Locally sent mail is working ok, as is OWA but I cannot send mail to any of the created domain addresses. When verifying the addresses at network-tools.com it shows that mail.domain.com is refusing connection. Any idea as to what have I done wrong?
