This talk is just me describing the design of my current email setup: How I receive them, how I filter them, how I read them, how I send them, etc.On the surface this is potentially boring, but the actual purpose of the talk is to showcase how the Not Invented Here syndrome has organically manifested itself in my day-to-day email-related interactions without me ever really noticing it.The core part of my email stack currently includes:one of my servers;my laptop;the programs offlineimap, unison, mutt;a somewhat brittle IMAP folder filtering system I made but never documented; andthe things I forget.It works well, but is not readily portable and only partially good design. Judge for yourself!
