I hear you Mike, More correctly from my perspective, perhaps these ISP domain IP address ranges provided to customers for their domains were originally blacklisted some time ago due to them being a high SPAM source? But blacklisted, they are, and if this was ever corrected they have not been reinstated. Even if I use my Telstra "Bigpond" web mail account! It bounces. The only way I can e-mail Comcast is via my hotmail account. It is definitely a problem they have with my ISP hosted domain's. Perhaps one day it will be fixed. Regards Sean P.S.

SPAM filters attempt to identify SPAM messages at the server or client system, and so mark/isolate/or delete them accordingly. The SPAM filter may hold known e-mail addresses of SPAMmers, but nearly all (if not in fact all) SPAMmers never use the same e-mail address twice, so to do so is basically a total waste of resources.. The blacklists, meanwhile, block messages from entire domains, i.e. every e-mail address at the listed domain.

The problem is that Comcast do not appear to be maintaining some very old SPAM filter lists, some of which I believe originated in Holland?. For Telstra/Bigpond to be blacklisted does not make sense, they are one of the biggest and most profitable Telco's in the world. The're no small Tinpot ISP that for sure. Perhaps this is some commercial deal?? The thing is to get this fixed, somebody has to be maintaining what ever SPAM filters they have running. We all know how that works in IT! We'll get a "roundtoit" Ever seen a roundtoit?

There are hundreds of blacklists, and around four dozen of them are significant (heavily used by e-mail servers). If Telstra is on the blacklist Comcast's uses, all e-mail received by Comcast from Telstra e-mail accounts will be bounced. 99.99% of the domains that get on any of the blacklists is because SPAM has been detected as originating from the domain somewhat regularly.
