I figured it is time to give an update:  we've tried a few things so far, 
short of upgrading to exim4 and doing Steve's patches.  I've seen mail go 
through now,  so one (or more) of these things have moved us forward.

First, we set the maximum number of messages in one connection to 99 from the 
following in the exim config:
smtp_accept_queue_per_connection = 101

Second, at some point in the past, we commented out smtp_verify:
# grep smtp_verify exim/*
exim/exim.conf:#smtp_verify = true
exim/exim.conf.1:smtp_verify = true

We uncommented it.

Finally, I added a spf record for our domains:
http://www.openspf.org/

One or all of those contributed to verizon letting my mail through, our queue 
is still not clean, and an upgrade to exim4 is still planned so more work 
needs doing...

Thanks,
-john
