That doesn't necessarily follow. Provided they know that the connection is
from one of their authorised dial-up users (remember the original posters ip
address was in the DUL) then they can allow any messages from there regarless
of the envelope sender address.
It is (very remotely - with dialup) possible that the dial-up user is
allowing messages to be relayed through his MTA (possibly without realising
it) - but even in this case the spam blocking services normally regard the
ISP as an "outgoing" relay with slightly less stringent controls.
I have broadband connection and as you can see from the headers on this
message it is relayed through my ISP. Now they DO suffer from customers MTAs
as relays, but they have restriction in the AUP, and (I am led to believe -
my firewall would drop attempts) they actively scan for relaying
