All this discussion of hey.com got me thinking about email filtering again. So I have reinstalled
imapfilter. If you’re unfamiliar, it’s a command line program that uses a lua script for a config, and lets you run complex rules against your mail. I’ve run it previously, and had a pretty complex filter set which you can see in my github dot files repository. Right now all I’m doing is filtering VIPs and newsletters. I may share more about my approach later. If you find you mail clients rules to be a bit limiting, and you’re not averse to some scripting, imapfilter is a great tool. It is in all package managers.
