Long time ago I used to run qmail for my school (about 2000 users). It was a lot of fun to do as a student sysadmin. Today, I'm tempted to build a minimal mail system for 1-10 users using agentic coding and use it for less critical use-cases like email for shopping/restaurants etc account registration. I wonder if I can get a safe and secure minimal build done completely agnatically without having to directly look at a single line of code.
