Of course. As said, if the list causes only people with *dynamic* IPs to
be forced to use their ISP's MTA, I'd agree that it's a very good idea.
But if we start using a policy that declares all endpoint-to-endpoint
mail illegal, allowing the direct to MX SMTP privilege only to large(r)
sites, then we'll set ourselves back to some form of uucp, and
practically start to advocate a single policing global mail hub that's
in the end responsible for everyone's mail. I'm sure it would require a
MS Passport account ;-)
I'd *hate* that to happen -- it defeats the point of the internet
itself, where individual people aren't just hapless consumers but
can be producers as well if they choose to.
[SNIP good points about pressuring ISPs to act responsibly]
But where do you stop the accountibility chain? At which point (size!)
do sites become responsible for their own actions?
Indeed, the only sensible answer seems to be "if it has a fixed IP
address". Not whether they are intermittently connected, whether they
use PPP, or what their bandwith is. That has nothing to do with it.
In short, "dialup" is the wrong name. It should be "dynamic IP".
Cheers,
Emile.
