Russ,

Since no one commented on this I figured that I should add a third cent.

The bottom line with any sort of service that charges a fee for adding IP's to a whitelist is that it will largely attract customers that have issues with being blacklisted. There is no doubt that most such services do not desire to be responsible for spamming, but they are often not capable of verifying that every customer's supposed opt-in list is from a first-party source and uses exclusively verified addresses. While places like roving.com (Constant Contact) probably have over 95% fully legitimate customers, as much as half of the E-mails that I get from these services are spam. The difference is due to the volumes.

I have in the past reported issues with known spam operations being bonded and I was not happy with the resolution that they took in either case. I believe that your experience will show that there isn't likely a net benefit to using BondedSender. Clean sources shouldn't have issues being blacklisted, and dirty sources should be scrutinized, especially when they service a wide range of unassociated customers.

Blacklists also of course have issues with these mixed/shared sources, in fact the lack of granularity in IP or domain based tests with such sources is one of the primary reasons for the problems. Another issue is that blacklists are fairly unforgiving in how they list such things, and end-users are not often concerned enough about false positives on legitimate advertising to seek having them delisted. This forced me to create my own list of domains and IP's that correspond to bulk-mail providers so that I could isolate their traffic and score them differently than I do E-mail. Some are passed automatically except for extreme circumstances, and others are held automatically and I whitelist only what customers report, and I whitelist specific mailings by things like Reply-To addresses and not the entire service.

What's the general consensus on the BondedSender test? I looked back through the archive, and found a little debate on it. I know Matt said he removed the test completely. I've never enabled logging for messages that pass until today. And right off the get-go I get 2 that definitely shouldn't have passed, but bondedsender said they were good...
