I don't believe the exim version would matter, but it's 3.35.
This server is behind a hardware firewall (sonicwall). The server that mine
is trying to connect to is mail.chartertn.net [209.225.8.131]. They are
using CommuniGate Pro 3.5.9b according to the message received upon connect.
I recall someone else having this problem as well, but the tcpdump is
different I believe.
tcpdump:

Delivering to fallback hosts
<snip>
The fallback delivery FYI did complete successfully.
IF I bypass the firewall using a dialup connection, this message will get
delivered. (They won't let me use our connection to bypass the firewall which
is why I used a dialup which I can use)
Is there anyone else with a similar configuration having this same problem?
I'm interested to see what receiving mailservers are experiencing this
problem.
