We are currently facing exactly the same problem, we are bound by contract to force TLS between certain DOMAINS and not hosts, since MX records can change!
We are about to change from symantec messaging gateway to a utm9 based solution, and the lack of this feature is a showstopper for us.
Does anybody know if there is a workaround to achieve TLS being mandatory for outgoing mails for certain domains instead of hosts/nets?
Thanks a ton in advance!
