Even though mxtoolbox reports the mx lookup succeeds with the correct IP address and the diagnostics report everything is OK, I cannot telnet to the server on port 25. I should be able to "telnet mail.mydomain.com
25", but this times out as it doesn’t appear to respond on port 25. mail.mydomain.com is resolving to the
correct IP and you can see from the mxtoolbox that the mail server responded
(somehow) and communicated with and mxtoolbox via mail commands "HELO"
etc.
Any ideas?
