Why not just set up something similar to www.senderbase.org where we all report the number of messages received from each server and each account. Any server or account that has an uncharacteristic increase in messages can be blocked or flagged to the server operator.Hey, I work for Cisco, let me poke the IronPort guys about their SenderBase stuff... ;-)
IronPort (for email spam) is expensive. Of course, there's nothing wrong with charging for a valuable service (it may even be necessary for a for-pay service initially, since the xmpp spam problem seems to be limited to only a few big services at this time.) In the long run, not everyone would be willing to pay. So, IronPort could be part, but not all, of a solution.
Ideally, if IronPort got into this business, we would want them to expose their blacklist using a common protocol. e.g. SpamHaus is queried just like every other public DNSBL, but they charge for the service.
