List of open SMTP relay servers

This probably teeters on the realm of ethical, but I have to do some testing for a scenario, and I need to detail what a spoofed email coming from an open relay looks like (headers and such).  Does anyone know of a repository of open relay servers?  Everything I've found so far is either outdataed or just leads to software to test for open relays.

If this crosses a line, feel free to delete.

Re: List of open SMTP relay servers

I get a free open smtp server, without credentials, from my ISP, sent some spoofed mail between teachers, as a joke (which they liked), anyway, they restrict it to their own IP ranges, maybe your ISP has something like that?
