You'll need to disable that feature of the firewall, and let Exim
do its job.

The "s_client" command treats Upper-case "R" at the start of a line
as a "Renegotiate" command. It is not a TLS netcat, it is a
debugging tool for exercising various TLS features. You can use
"rcpt to:" in lower-case if you like, but there's no point...

The problem is with traffic that transits the firewall.
