Exim remote_smtp is giving me errors and I'm stumped

Hi there,

I use exim (via cygwin) and it is no longer sending emails to my blackberry.  The errors are going beyond my limited knowledge of mail setup and I'm looking for help.  

THE SETUP: I have a WindowsXP box running cygwin.  I bring email in from my ISP via fetchmail and send it to procmail.  Procmail does some filtering (spam and otherwise) and then tries to send the appropriate emails onto my blackberry.  

WHAT IS HAPPENING:

The way it does that is by passing it to exim.  This has been working fine until May 25th.  At that point, I got my first error in the exim log (changing the emails/names, of course)

2007-05-25 03:11:51 JIL83R-0002RW-F6 <= name@nospam.com U=Name P=local S=5633 id=77

nnection: host mx14.bis.na.blackberry.com [216.9.248.39]: 554 as12a.bis.na.blackberry.com

That error continued until May 28th, when I got this in the log:

2007-05-28 20:56:41 JIS5EH-00026S-A0 <= name@nospam.com U=Name P=local S=3649 id=31

ection: host mx12.bis.na.blackberry.com [216.9.248.37]: 421 #4.4.5 Too many connections to
 this host.

After that, about 15 minutes later, one of my emails DID go through, oddly enough.  After that though, on May 29th, I started getting this error message:

2007-05-29 05:22:55 JISSU6-0002R8-DX Remote host mx12.bis.na.blackberry.com [216.9.248.37]

 closed connection in response to initial connection

And finally, since then, I get this error message:

2007-05-29 05:31:52 JISSU6-0002R8-DX == name@tmo.blackberry.net <name@tmo.blackberry.net> R=dnslookup T=remote_smtp defer (-53): retry time not reached for any host.

THE QUESTION:  So, I'm trying to figure out what is wrong.  It looks like for some reason, blackberry.net stopped taking connections from my machine.  

If I run "exinext name@tmo.blackberry.net" I get this now:

Transport: mx14.bis.na.blackberry.com [216.9.248.39] error -18: Remote host mx14.bis.na.blackberry.com [216.9.248.39] closed connection in response to initial connection

Any advice for how to fix this???
