I did wonder that, as the config I'm testing does have a firewall in place
(I'm wanting my anti-virus server as secure as possible hence not being in
the DMZ).
I currently have my firewall allowing and logging all traffic between the
servers. It is showing the initial connection from exim to port 3310 and
what are the ftp sessions on other random ports, such as 1402, 1121, 1331.
