Subject: [exim] smtp closedown on verify connections
Is there anything odd about the shutdown of the smtp conversation
used by exim (4.50) for a verify?

It's that "unexpected disconnection" I'm interested in. I'm guessing
it's a recipient-verify from the sending system.

(I'm ignoring the doubled sender-verify-random for now)
