I've installed Exim 4.20 on RH 9 from the rpms. I am able to send and
receive mail as I want, but...
I have a single address that I am not able to send any mail to from this
MTA, even though I can send mail to other addresses and can send mail
to this address from other mailers. DNS is resolving correctly and the
message goes through the router/transport process fine, but something is
failing in the actual delivery. The exim logs give me no insight.
A debug trace (with the domain names changed):

The line that catches my eye is:
smtp.myisp.com [64.224.110.142] status = unusable
Why would this be?
