[ale] AT&T blocking 25

[Brian Schenken]

I think "residential" service can opt-out too.  It certainly should be able
to.  It's sold as a preventative measure, you certainly shouldn't have to
pay extra to have certain ports open.

Some people run mail services for their families... websites... even old
timey telnet BBS's.  I understand blocking ports to generally keep botnets
and open relays off your network.  And I agree - as long as those of us who
don't require said measures aren't forced into them. It should be the case
that savvy people make better of their resources - not guiltily accept a
penalty for being an advanced user...
