SPF -- I get less spam

I configured SPF (Sender Policy Framework) on sagar.org and my spam seems to have gone down significantly. 


Of course, that could be coincidence, Google may have just improved their filtering algorithm in the meantime.  There's only one way to know for sure ... turn off the SPF and see if the spam goes back up.  I'll be doing that, but the changes take about a day to propagate, in which time I'd have to look forward to 10000 spam.

It's also possible that the spammers are actively seeking out domains that don't implement SPF when they choose the return addresses for their messages.  I know I would.
