Spam to a new domain isn't uncommon. Lots of spammers comb whois, search the web, scrape forums, looking for any domain they can find, and then they try mailing to variations of made up addresses at that domain to see if they get through to a real live mailbox. So, setting up a new domain, and catching all email to the domain, this invariably means that very soon after creation, I'm likely to get 200 pieces of the same spam, addressed to different made-up address variations.
But this time around, it's happening a little bit differently.
