That's a lot of spam!

I'm not seeing footers on the emails at all.

Two or three emails did get through the filters, two from "Victoria

Victoria@sovereignsymbol.com via leafe.com" and one from "The Edge Men Want

support@laverdaddemonagas.com via leafe.com"

Let me know if I you need more info, I can forward them to you off-list.
