Tim Morgan's thoughts that are too big for Twitter
The perils of community-based spam filtering

OK, so unlike the rest of the world, which uses Gmail, I run my own mailserver.  I do server-side spam filtering with SpamCop, a community-based spam-filtering system.  Lately Facebook has been nagging me every time I log in: “We require a valid email address for all our users. Please enter a new email address or reconfirm your existing one.”

I opted to reconfirm the existing one a few times, but after consistently not receiving any new email, it was time to investigate.  Following my mail logs I noticed SpamCop was blocking emails from Facebook.  Since SpamCop is community driven, this basically means one thing: SpamCop users are indicating that emails from Facebook are spam.

Which is great for them, I suppose — if they don’t want to get emails from Facebook, then this is a quick and easy fix for this problem.  The problem is I do want emails from Facebook.  See, unlike these guys, I actually went into my account settings and checked only the emails I actually care about.  Sadly, people like me lose in a system like this.

Anyone got any better server-side spam filtering ideas?
