Problem making mail connection; FC5

I am currently running exim4.5 on a FC5 box. Mail to jetvac.ca goes undelivered. My Box is fully patched. I get very slow response telnetting on port 25 to mail.jetvac.ca (69.157.195.243) however,

If I use putty or a Solaris or AIX box I get immediate response

220 mail.jetvac.ca Microsoft ESMTP MAIL Service Version 5.0.2195.6713 ready at <date timestamp>

Mail deliveries to other hosts are successful.

I have tried with other FC5 boxes and none work.

Seems like there might be a problem on the other end talking with my FC box.

Does anyone have any other debugging techniques I might use? Looking into tcpdump now.

TIA
-Thomas
