ISPs don't need to charge customers for the privilege of unfiltered
outbound port 25 access; all I ask is that they tell customers it's
blocked and require them to specifically ask for it to be unblocked rather
than give it to them unblocked by default. The vast majority of broadband
customers don't need it and those that do generally know enough to secure
their machines.

I don't see it as punishing people, I see it as securing an commonly and
easily abused resource. This is similar to the 'why are you blocking my
open relay even though no spam has been sent through it (yet)?' arguments
a few years ago.

FWIW, my mail servers are on a residential DSL circuit with a block of
static IPs, proper forward and reverse DNS, relay tested and secured, with
proper SWIP entries. I *still* had to smarthost through SBC when
RoadRunner arbitrarily and against their stated policies dropped my
traffic with zero warning or recourse. Contrast that with the hundreds or
thousands of pieces of spam that haven't made it into my network simply by
dropping connections from known dynamic broadband pools (including those
from RoadRunner.)

I've seen both sides of this - far more abusive mail traffic emanates from
dynamic broadband pools than does legitimate traffic. Forcing that traffic
through the broadband ISPs mailservers would shift the cost from those of
us being spammed by broadband netblocks to the ISP *where it belongs*. The
ISP's mail systems will either crash and burn, or the ISP will find a way
to curb spam on their network. As it is now, they just leak that crap all
over the net and expect the rest of us to pay to clean it up.
