That is postfix-2.12-20140209, and shows exactly the behavior that
we implemented. It tries to deliver via TLS, the server hangs up,
then Postfix immediately tries to deliver to the same server via
SMTP, where the server also hangs up.
Now the big question is why does this produce a different result
from the queue manager's point of view than postfix-2.12-20140109
which does not fall back to plaintext. In both cases the last error
is exactly the same: the server hangs up.
