Also, XMPP has almost the exact same set of problems as (MTA/MTA) SMTP, and seems to have deployed TLS with PKIX auth just fine, and the deployed network is shifting with some pace toward this being mandatory.
The only additional issue for SMTP is that you'd need SNI, but that's not terribly onerous these days.
