mail problem

["George A. Dowding" <george@scifish.com>]

I am using exim as my MTA.  I have a DSL with a static IP.  Every once
in a while mail can not be delivered to certain hosts.  I have
sucessfully sent a one line message to that host, but anything larger
causes this time out error.

What can I do?
