Let me throw another thing in here...

Philip mentioned testing without problem with an appendfile delivery, but in
my setup I was delivering to Cyrus using the "smtp" driver with the "lmtp"
option. I'd imagine Exim must be adding CRs to messsages to make it legal
SMTP/LMTP? Maybe Exim's doing that a bit too eagerly?
