Modern Anti-Spam and E2E Crypto (2014)
This tangentially relates to something I was thinking about yesterday.<p>Does anyone have a sense of how difficult it would be to create a service that scans your gmail spam folder and categorizes the contents into &#x27;definitely spam&#x27; and &#x27;maybe spam&#x27;?  I&#x27;m probably somewhat of an edge case, but I get over 100 spam emails per day in my spam folder.  Almost none make it through to my inbox.  However, every month, one or two legitimate emails land in spam.  Usually these are there for an obvious reason - &quot;cold call&quot; emails from advertisers and that kind of thing, but still stuff that I want to see, and obviously (to a human) not on the same level as penis enlargement garbage or whatever.  (Although occasionally there are real head-scratchers, like I thread where I&#x27;ve already replied to someone twice, and then their third message goes to spam.  I guess gmail&#x27;s filters only operate on the current message and don&#x27;t look at history.)<p>Anyway, I get enough false positives that I need to scan through the thousands of spam messages I get each month to try to find them, which is obviously a huge waste of time.  If something could go through there, identify the least spammy fraction, and label them, it would save me a ton of time.  It would be lovely if gmail offered this themselves, since they already have the spam <i>score</i> for each message.  But barring that it seems conceivable that you could do it with a browser add-on, perhaps using a neural network.  Still seems kind of like reinventing the wheel though, since you&#x27;d basically be building a reverse spam filter.  So I&#x27;m wondering if there&#x27;s an easier way...
