I posted this on the forum much long after contacting support directly.. and they didn't think it was a DA issue at the time. They tried to point it as a freebsd problem.
I am running exim version: ESMTP Exim 4.66 Tue, 08 May 2007 14:53:34 -0400, with exim.conf stating "RSS-1.0da"
new list/old list, still same problem.
