That’s a python app... I would like to know how to communicate with a .app bundle. Can I communicate directly, do I need to create an xpcservice, or something else. There’s no documentation anywhere on the internet. feel free to move this to a more appropriate forum.

A little late... but it’s still not listed: https://apps.apple.com/us/app/sessionrestore/id1463334954?ls=1&mt=12

this should say: and the actual Mail From address will be something like: random_uuid @ example.com in my developer account I have added example.com, and the actual email address I use to send from. For example: news @ example.com

I finally figured this out. Kinda silly oversight really. I had set up my MAIL FROM domain in Amazon as mail.blah.com but in Apple I was only verifying email(a)blah.com As soon as I added email(a)mail.blah.com the emails were delivered.
