I agree !

But I don't know what I have to fix at firewall level ?

What are the tcp/udp port involved ?

The exim4 is behind a firewall in a DMZ with private IP adress NAT (port
fowarding).

Unfotunately we have only 1 public IP (the firewall one)

Maybe I have to forward some port (ICMP ?? but then I cannot ping the
firewall) from the firewall to the mail server.

What you think ?

thanks
