I suspect that was some kind of temporary aberration. SBC started
blocking port 25 in the last two months, and during that time I've
helped at least a dozen of our customers using SBC DSL switch their mail
program settings from port 25 to port 587, with no trouble -- it worked
in every case.
I bet it works if you try it again now (as you say, blocking port 587
makes no sense).
