Peter N. M. Hansteen asks the question, "Does Your Email Provider Know What A "Joejob" Is?" in his blog and provides some data and discussion. He provides anecdotal evidence which seems to indicate that Google and possibly other mail service providers are either quite ignorant of history when it comes to email and spam, or are applying unsavory tactics to capture market dominance.

[Ed Note: I had to look up "joe job" to find out what it is. According to wikipedia:

A joe job is a spamming technique that sends out unsolicited e-mails using spoofed sender data. Early joe jobs aimed at tarnishing the reputation of the apparent sender or inducing the recipients to take action against them (see also e-mail spoofing), but they are now typically used by commercial spammers to conceal the true origin of their messages.

    SPF gets a bad rep because it was touted as a "solution" to spam by people who ought to have known better - it's not a solution to spam, but it is a *very* effective deterrant against people using your domain for a joe-job, or even collateral damage from trojans that use random senders from an address book when spamming their way through the rest. Whenever I've setup SPF (ideally with the "-all" option) the amount of email backscatter from spam has dropped to near zero almost as fast as the DNS records could propogate, making me think that spammers actively check for the presense of SPF, DKIM, etc. and if found actively avoid the domain as a faked sender, so definitely worth doing.
