Whoa, having been in IT since the dawn of time I'm impressed this relatively simple attack on smtp worked.

Prepare for a humongous inrush of spam before servers patch this one.

But it's already patched by GMX and Microsoft.

As far as I understand it, it doesn't affect single mail servers, but only mail systems where you have separate inbound and outbound servers and the outbound servers trust the data they get from the inbound servers.
