Hi;
The log is below. The O/S is Windows 2003 with all the latest service
packs. The MX record is good because we get email fine from the rest
of the world.
However... the MX record is for the external IP address of the mail
server, not the internal one (we use NAT on our firewall). And the
webserver box is also our external DNS box.
??? - thanks - dave
