Site email seems to have been broken for 6 months. It's fixed now and the queue is clearing. Sorry if you suddenly got slammed with a backlog.

I was wondering what triggered it. I also have an auto-forward setup to my gmail acct to get stuff on my phone. It triggered spam time out on my mail server. Good times.
If I wanted to be ignored I'd go to work.
