commit 2d5a73c55dfb4f34930cd0a1af3a741372a4ceb2
Author: Oswald Buddenhagen <o...@users.sf.net>

don't hang after failed start_tls()
we'd send a LOGOUT command in plain text while the server was already
expecting an encrypted command, which would typically lead to waiting
for more data and thus an indefinite hang.
so close the socket immediately instead of letting the normal shutdown
path take care of it.
inspired by a patch by Steven Flintham.
