Stupid stupid spammers
October 14, 2006
So what the heck is the point? Those addresses are all official or official-ish addresses. Anyone who sees mail to root, uucp, administrator, etc, is running a node on the internet, and will almost by definition HATE spam, spammers, phishers, and spyware. These are people who will, at their kindest, do what I did. Someone who is more motivated will write filters to gather spam signatures from these clearly bogus emails to help automatically filter spam out of other accounts.
There are numerous things we could do to more effectively filter spam, but for reasons completely unclear to me, all the big players who could make it happen, do not. Google? Yahoo? MSN/Hotmail? Apple? Thunderbird? (Thunderbird must do this already, I’ll go look). All these guys could start signing emails by default with hashcash, or a verified PGP id, or with a vendor-supplied certificate that verifies mail from an actual customer and give a lower spam score to any mail that was properly signed. As the signatures become more widely adopted, the bias against unsigned mail can be cranked up.
