CheetahMail Headers - 2007/06/20 17:51 Looking over the headers for an e-mail I received through CheetahMail today.

They have list unsubscribe info in the headers.

No DomainKeys or DKIM signature, or anything else out of the ordinary at this time at least in the e-mail I received.

Very interesting whitepaper on their Web site. It talks specifically about deliverability to MSN/Hotmail, AOL, and Yahoo, with some briefer info on other ISPs.

Identifying and Managing Domain-Specific
Deliverability

Re:CheetahMail Headers - 2007/07/03 17:31 I have friend that uses CheetahMail at American Express. Overall he said the product is up to par however extremely overpriced. He's convinced that half the ESP community has the same product for a quarter of the price.

Re:CheetahMail Headers - 2007/07/11 00:19 I guess that goes to show that blacklists and accepted rates don't always go hand-in-hand, which likely has more to do with the (lack of) validity of some of these blacklists than anything. ---------------------------------

It may not be a validity thing (although it has been seen that not all lists are created equal - thanks Al Iverson: http://stats.dnsbl.com/) but in many cases it is a foot print thing.

5-10 - no one cares about
SPAM CANNIBAL - uses tarpitting and is harder to diagnose from a sender POV as the connections just sit and do nothing
WPBL - Just has a small footprint and it not widely used.
