We're playing around with greylisting and other spam reduction stuff here, and in the course of that I fatfingered the whitelist a week ago without noticing. So if you're seeing posts with old dates, it's because I just fished them out of the spamtrap.

Worth noting that we're not greylisting anything but personal addresses at this point... no mailing list stuff, and we'll probably never greylist on those.

But for spam control on my own account, greylisting has been incredible... around a 90% reduction in spam.

(Greylisting is where the receiving server temporarily rejects incoming mail and depends on the sending server to resend it later. Spammers don't resend, legitimate mail servers do. It creates a delay the first time someone sends mail to a particular address, but after successful delivery, they get whitelisted automatically.)
