I had a thought yesterday that I wish I had before I hit the publish button
on the article: Perhaps the answer for people who need an exception case for
port 25 blocking is port 587 or even some non-standard port. I checked and
my own mail server supports both. Put SMTP on port 1125 or something like
that for your external users, or use 587 and require authentication. Is
there a reason this wouldn't work?
I'm also going to contact SBC and ask them how their opt-out system is
working so far.
