Ok here is what I want to see.. I want exim to have a feature that will take the envelope sender... MD5 encrypt it and compair it against a DNS server such as what MAPS/DUL/RSS but with md5 hases. Example:
Adding zinkmet@???
dc32ab79148f69773e82fc98c83b555b
Adding zlite.com
26d59a5353b0e30848f0233e7749b6e4
Adding zone76@???
66bcd5967d3c6e0b71d32a666f8b36a2
Those are examples... So when exim does a lookup against the specified DNS server it would do somthing like so:
take zone76@??? MD5 encrypt it to 66bcd5967d3c6e0b71d32a666f8b36a2
then perform this query:
nslookup 66bcd5967d3c6e0b71d32a666f8b36a2.domain.com (similar to what maps does) this would give everyone a tool to help stop spam.. now if you know of someplace or that does this with the senders address then please let me know.. I am sick of getting spam.. even with useing maps/rbl/dul I still get the stuff... MAPS/RBL/DUL use sender hostnames which can change at a drop of a hat. I want to take this approach to futher eliminated UCE... anyone with me?
Later,
Brian
