Anyone have contact with Microsoft network ops? They've blackholed my SMTP (204.11.50.134) (which is used by me and half a dozen other people, none of whom send spam), and my admin's on vacation and I don't wanna screw up his time off. This is obviously a false positive though.

@pluralisticCory Doctorow It's a rite of passage. You haven't run a proper mailserver if you haven't been blocked by Microsoft mailservers at least once in your life.
