Let's Fry Some Spam!
For a long time, I’ve been using Postfix as my mail server, and it has a pretty good reputation for reducing spam simply using various header and RFC checks. After throwing blacklists into the mix, and without any other tool such as SpamAssassin, I had reduced spam by roughly 80-90%. But that still meant about a dozen succeeded in reaching my inbox, and the ratio was slowly increasing thanks to the recent vast deluge of pump-and-dump scams, so I decided I needed a solution.
