OK - this might be a way to simulate the problem. Set your /etc/resolv.conf in
the Exim server to some local caching name server that you control. Pick a test
domain and look up the name server BS records. hen on the name server machine
run this:

iptables -v -I INPUT -s ns1.domain.com -j DROP
iptables -v -I INPUT -s ns2.domain.com -j DROP

I hope this code is right. The idea being that you block your resolving name
server from accessing the name servers of the domain that you are emailing.
That's what happened to me. Due to the routing problem my nameservers couldn't
rote to the name servers of the destination and because it was cut off mail
bounced instantly as unroutable.
