smtps was deprecated years ago and is not implemented in postfix, hence the need for stunnel. I should have said they don't implement STARTTLS on either 25 or 587.
Oh, ok; I assumed you were talking about a client, not an MTA. Why are you relaying through Verizon rather than just sending directly? My home MTA on FIOS hasn't had any problems sending mail to the Internet at large, although I do have a static IP with appropriate matching/reverse DNS. Seems to be a lot less noise on this iteration of the shake fist at Verizon's lack of IPv6 thread, I guess everybody is pretty much burned out and given up 8-/. Verizon should just update their IPv6 status page with a link to hurricane electric's tunnel broker page <sigh>.
