Do you have an application-level firewall between the Internet and your mail server? If you do have, it may be deciding not to allow the connection to continue because of rules of its own. Check with your networking people to find out what is between your mail server and your Internet link.(Continue reading)
The exim server is on DMZ, the tcp/ip ports needed to comunicate smtp are
open.
In fact we receive emails from many domains but not from some domains.
I didn't setup any firewall rules to stop establised connections to
continue.
I can double check this, but I'm quite shure.
Moreover absolutely no special rule is on the firewall about the connections
from/to the backup MX server, but from there the email are arriving with no
problems.
thnaks a lot for the help
