Hello,

Would it help to stop spam by recording the IP address of the originating server when open SMTP relays collect mail? Record the IP address in the body of the e-mail, and record an IP address at each hop. Establish a chain of custody so I can track an e-mail back to the source IP address.

Thanks,

Howard Hong
