It seems as we become more widely known we get targeted with more sophisticated spam attacks.
The most recent attack was a "mail subscription confirmation" blitz, where "adam@pitbullgitars.com" seemed to have signed up for every mailing list in existence. I seriously had to delete 5,000 "confirmation" emails on Thursday and another 1000 on Friday and today.
The only way I could resolve this was to set some "mailbox rules" where any email that had the word "confirm" in the subject field would go straight to trash.
So, if you need to email me, please don't put the the word "confirm" in the subject field, otherwise I won't see it.
