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.

    In a sense greylisting does this. It delays the email in a SMTP compliant way (forcing the mail to be stored at the sender for some time, before retried). A spammer wants to send out as much mail as possible, so keeping track of time is an extra burden for the spammer to take into account (which they often don't do). The catch... valid emails will be received with a small delay.

    Greylisting doesn't work fantastically in my experience because a lot of the spam I get comes through either real SMTP relays that are fine with retrying, or the spam-generating botnet is content with opening so many connections, the server slows down anyway.

    Other people's misconfigured systems that don't retry mails and cause delivery failures are also an issue if your company is large enough and your partners are small/tech-illiterate enough...
