I remember when I imagined big companies might use their considerable resources to put together something like that. Then I found out it's just a handful of random engineers cobbling together crap and hiding it behind a fancy domain name.
It is probable that Office365's entire spam filtering system is a very large and ugly spreadsheet that gets passed around between a few teams using a ticketing system.
- vitaemec 6y agoI used to work on the O365 antispam team, and I'm not sure how much I'm allowed to say in public, but I'm pretty sure I can publicly say "a very large and ugly spreadsheet that gets passed around between a few teams using a ticketing system" is not accurate.

There's about 50 people on the team. DKIM/DMARC/ARC is worked on by two engineers.
