We're a small managed services provider, and we started doing
authenticated SMTP with TLS on port 587 six years ago. It's at least
in kindergarten :-)
Once we explain the advantages, our customers love it since their
email "just works" pretty much wherever they go.
As a former manager for a small resnet, blocking port 25 outbound is A
Good Thing. Cut abuse email down by a huge factor.
