I suspect that the implication of this is that there needs to be a change to 
assp. Here's my logic for that: 

1) large telephone company ISPs are the source of quite a lot of spam, as well 
as being the source of legitimate e-mail; 

2) in the real world, we'll never get these ISPs to react to requests to: 
   
   a) fix their DNS records; 

   b) prevent spam going out from their servers or computers on their networks. 

I suspect the only practical work around for this is for assp, once it knows 
that the domain is likely to be sending spam (i.e. after finding out that the 
IP and/or domain has badly configured DNS records, is in a DNSBL, or, say, has 
spammy content), to check the sender address against the whitelist, before 
sending the message to the spam folder. 

There's just no way we'll ever stop large ISPs sending spam as well as sending 
real mail. Reluctantly, we (i.e. assp) have to deal with this. It's not up to 
us (i.e. the receiving e-mail server admins) to remove these spamming ISPs from 
the DNSBLs. 

Anyone have any thoughts about other ways around this conundrum?
