I was trying to set up Apple Mail on my Mac because someone emailed me a .eml file that I seem to need Apple Mail in order to open. When I tried setting up my gmail account in Apple Mail it asked me to give permission for the app to read, edit, and delete emails.

**What I Want To Know: ** Under what circumstances would Apple Mail actually delete my emails form a gmail account that I set up with it? Would it only be when I manually delete them in the Apple Mail app?
