I would like to point my customers to port 587, but that kind of

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.
