It's happening for like 1 in 100000 emails (the host beiong deliverd
to is a little flaky), I commented out the contents of the true branch,
(because I was only seeing that code lose emails), and what printed
next was "Remote host closed connection in response to DATA"
I haven't tried to replicate it in verbose mode I'll try that
(delivering to netcat) next week.
