Understanding the motivations of mail service vendors
From a comment on my entry about how modern mailing services should work:
This is a common misunderstanding of the incentive structure in operation.
This is not an incentive to deal with spam, this is an incentive to not get blocked. The two are very much not the same thing. Very few people who use a mailing service care very much about whether or not it sends spam; instead, they care about whether it can deliver their email mailouts (and do so without having them scored as spam by the recipients). No one is actually paying the mail service to not deliver spam, so it has no direct incentive to do so; if anything the straightforward incentives go the other way, towards giving spammers the benefit of the doubt so that they keep paying.
(There is some indirect incentive, in that people sort of care about your overall reputation and your overall reputation is affected if websites have lots of stories about how you are a big spam source and have a spam problem.)
For many mail service providers, trying to block spam is one of the most cost effective ways of keeping your mail delivery rates up. However, if you are big enough you become like GMail, Hotmail, and Google Groups; you are too big and popular for anti-spam systems to block unless you become a truly epic emitter of spam. At this point providers lose much of their business incentive to block and reduce spam.
(Note, however, that every mail service provider does less than they could to block spam through their service because every MSP knows that if they adopted full best practices, they would go out of business because customers would find them unattractive. This should not be surprising.)
Nor do mail service providers have a real incentive to refuse to do business with all spammers. Some spammers make unattractive customers (they are unsavory, a big support burden, may attract legal attention, and are high risks to cheat you on payment). However, some spammers make very attractive customers; they pay on time and well, they don't cause you support headaches, they're reputable businesses, and so on. They just send UBE and want you to send it for them. See many examples (and also).
You may appeal to moral qualities as part of the 'incentive' that providers have to deal with spam, ie that they really intrinsically care about not sending spam and are not merely doing it because of business needs. However, mailing service providers (and their employees) have consciously chosen to enter a line of business that draws spammers to it and intrinsically enables spam. It's hard to avoid the conclusion that they consider some degree of spam a necessary evil in order to make money; from there, to misuse an alleged Winston Churchill witticism, it's only a question of how much spam.
