Paul,

I have an interest in continuing our discourse, however you still do not 
accept mail from my ISP. Thus, I cannot correspond with you on this matter.

If you wish to continue our conversation, please do so with an email 
address I can reply to. I strongly dislike wasting my time writing replies 
to your messages only to get bounces back.

Also, please in future mails please cite only abuse caused by properly 
relayed mail from comcast's MTA's, not stuff directly sent from clients 
that would be easily cleaned up by using a dynablock type list. (ie: the 
spamhaus reference you included is all client nodes, take a look)

My point exactly.

Really, that post was in response to an off-list discussion, so it would be 
hard to follow without recapping several large off-list emails.

My argument was not against using SBL. It was against using SBL's top 10 as 
a reason to create a categoric block of all netspace owned by an ISP when 
SBL is only listing client nodes not servers.

you can use sbl-xbl.spamhaus.org and test both lists with one check.  what
cf file do I need to edit to have spamassassin do this?

Their SBL does NOT list all Comcast dynablocks.  I use their SBL, and have
had to manually block large ranges of Comcast space because Spamhaus doesn't
pick them up.  For example, 68.85.198.87.  They're listen in their XBL, but
NOT their SBL.

Now that I know about their XBL, I can start using it (I think they set that
up after I had configured the main parts of my mail server).
