this is also one of the main problems. since there are providers offering
free dialup (even without registration!!) they are more attactive to
spammers than others.
for ISP's offering free dialup that can be abused i think a solution like
fredy's i quite nice (not perfect, but nice). but the main problem is, that
sending spam is much cheaper then snail mail, and since are a lot of idiots
using the internet and buying peppersprays or black socks from spammers, the
spamming will go on.
it's like a neverending fight between dark and bright side. but the ISP
should be on the bright side and fight for the 'free internet'. if we fail
one day (we come back to pascals post some weeks ago) we'll have to define
what should be open, because the rest will be blocked. byebye freedom
then...

RMX or on the other way AMTP is not the 'super-duper-solution' aginst spam
;-)
there will be people dont know how to configure or even implement it.
and even if implemented where will be some problems.
let's say you host domain XYZ.com and allow your customers to send email
from your ip range. what if that company has people in germany working for
it, then you have to allow whole t-online?
what if the spammer uses not a real domain but a dynamical domain (e.g.
dyndns or XYZ.ch.vu). he might be allowed to send mail out. i'm sure
spammers can circument those configurations with own infrastructure of
something like that.

and dont forget: you will never put a rule "dont accept mail from NON-RMX /
AMTP servers". because you know, that the internet is fast growing but slow
changing. remember IPv6? how many providers world-wide have implemented it
yet? 2% 1%? i dont know. but i dont know many people reading NOW this list
will be able to see IPv4 disappearing from the net...
