Signatures and Spam Filters
Filed under:
long time ago I argued that more people ought to digitally sign their E-mail messages. Unfortunately, very few people bother to do so. There are many benefits to encryption-based verification of one’s identity. Ultimately, it can lead to more trust, which can in turn prevent spam and make communication less susceptible to ‘noise’.
There recently emerged a word-of-mouth that signed messages are less likely to be intercepted by spam filters. As to whether this is true or not, I would have to say I doubt it. I am sorry to antagonise some people’s hopes, but several messages that I PGP-signed got flagged as spam (not by SpamAssassin). At least I was informed in all (probably two) occasions, but it was nonetheless worrisome. Quite recently I mentioned a trend whereby banning of autoresponders becomes prevalent. It is very important that moderators up above can discern spammers from those who attempt to fight spam in genuine and effective ways.
