They don't seem to care much about the behaviour after a 4xx response to
STARTTLS either, so I'll quote RFC 3207 in a last attempt to try to elicit a
response before I go back to lurking...
If the client receives the 454 response, the client must decide
whether or not to continue the SMTP session. Such a decision is
based on local policy. For instance, if TLS was being used for
client authentication, the client might try to continue the session,
in case the server allows it even with no authentication. However,
if TLS was being negotiated for encryption, a client that gets a 454
response needs to decide whether to send the message anyway with no
TLS encryption, whether to wait and try again later, or whether to
give up and notify the sender of the error.
