No it doesn't, and it is unlikely to, since the only standard protocol
for email is ESMTP, which uses the STARTTLS mechanism to initiate
encryption.
The only facility is -tls-on-connect, for legacy clients that use smtps.
The recommendation is to use inetd to handle this "second version of
Exim", which of course doesn't actually have to be a second version.
