Ah, blacklists. One of the companies I work for is on the RFC-Clueless blacklist. Gmail handles the business mail, but something was screwed with the abuse@ and postmaster@ mailboxes, so RFC-Clueless listed the domain years ago. Eventually we started running into trouble with mail admins who used RFC-Clueless. I got gmail involved, escalated to third-level support, and got those two RFC addresses fixed. I've submitted this fix to RFC-Clueless several times over the past few months, but it's abandoned. Every request times out after a few weeks. Great, we're on a blacklist whose raison d'etre is "blacklist those not following the rules", and the bastards don't even follow their own declared workflow.
