Hey there HN, I just build this basic SIEVE email filter editor. I usually struggle with keeping my email filters up to date and in the past few years I've set myself away from major providers like M$ or Google, so I had to fall back the big ol' SIEVE to do filtering. After a long time doing it manually, I decided to just build a GUI to edit the rules, since I didn't find any GUI editor out there. That's it, just a commodity tool, nothing fancy. Hopefully someone will find it useful :D
