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.

Sure … and when you write an email from your laptop you better make sure your laptop remains running and connected to the net until the mail is actually fetched. Because if you don't, the receiver might fail to get your mail.
The Tao of math: The numbers you can count are not the real numbers.
