The last mention of JMAP got me to sign up for three years of Fastmail. I used their auto-configure script to add it to my personal MacBook. The system then became more unstable than it has ever been, frequent crashes of the WindowServer and complete system lockups. Combined with scary messages about my Gmail and iCloud accounts asking for re-authentication. I seriously thought I had been owned.
I removed the Fastmail accounts (mail, calendar, etc.) and everything was immediately fine again. I'm scared to try this again to troubleshoot what is happening.
