Most ISPs have limits on the number of messages that their mail server will 
receive from each IP address.  So if a spambot can send direct it can send 
hundreds of messages per second, but if it goes through the ISP mail server 
then it is limited to only a few per second.

If the ISP does not quickly stop the spam then their server will end up in the 
SpamCop listing.  So again it's not a problem.

Of course not.  They can get an account on a Linux machine somewhere sane and 
use a ssh tunnel.

Maybe you aren't as popular as I am.  Even with greylisting and DUL I still 
get more spam than I like.

There's another thing we could do instead of using a DUL.  We could complain 
to the ISPs in question when dial-up links spam us.  Complaining by email 
doesn't work, so we would have to use FAX and phone calls to the support 
lines of the ISP.  If enough people do this then the ISP will block outbound 
port 25 connections just to save the cost of dealing with the complaints.  
Then the people who want to run mail servers on dial-up IP addresses wouldn't 
complain to us, they could complain to their ISP but that wouldn't do any 
good either.
