You might wish to re-examine your stance and check the vulnerability on your own system. I have the filters in place from APLUS.net. I have a router and the Firewall up. I have a Navy Trained Tech running the show on this side.

I'm not having an issue with spoofed. I am having an issue with Increased Nigerian Scams being sent to me. The site e-mail list has been hijack apparently and you want to throw your credentials in our faces like you know better.

You might want to see who is stealing your e-mail list internally... But do not attempt to talk down to the members who as experiencing legitimate issues and have traced the cause to this site.
