If spam starts being sent with a From: field that matches the computer that is
being used to send it then that will be a huge improvement.
In the good-old-days when I received less than one spam per day (before anyone
had felt the need to write anti-spam software) I could count on the From:
field being correct. This meant I could abuse the spammer and ask their ISP
to terminate their account...
ISPs that don't stop spam going through their servers can be added to
black-lists without any debate, such ISPs are just bad. However ISPs that
merely allow outbound port 25 access from their dial-up pool can't be held to
the same level of accountability.
