Yes, it would take a long time to spread considering there's a whopping 388 domains out there using DNSSSEC for SMTP, the majority of them run by neckbeards and not commerical email services. 388 Zones have deployed TLSA for SMTP with STARTTLS (Port 587) I don't expect this to catch on, ever. http://secspider.verisignlabs.com/stats.html http://secspider.verisignlabs.com/stats.html
