I just pushed to master a fix to this issue https://github.com/mailpile/Mailpile/issues/2217 - this SHOULD fix the “Johnny, You Are Fired” PGP signature verification bugs. The fix should hit the Nighly build tonight, and if nobody complains I’ll push it to the release candidate branch as well next week.
I haven’t had the time/energy to fully test the fix though; in a perfect world someone would go to https://github.com/RUB-NDS/Johnny-You-Are-Fired , download the tools and re-test Mailpile after the fix…
Posting this here to see if anyone wants to pitch in. Any volunteers?
