Yes but IMO we should be moving toward a world in which TLS is mandatory for
SMTP relay. Clear guidance to implementors
and operators on what TLS versions, cert algorithms, and ciphersuites a client
and server should support, might help us get there.
I don't think that's the problem. I don't see any SMTP TLS failures other than
from spambots.
(perhaps as a stepping stone, cleartext mail relay could be pessimized ...
We already have mta-sts, which says that cleartext is forbidden for
the domains it's published for. Why reinvent another wheel?
