If you prefer the email list to appear in reverse chronological order with the most recent messages showing at the top, you can activate a configuration switch on iOS to achieve that result.
How to make the most recent posts appear in the iOS mail app first
- Open the "Settings" app on your iPhone or iPad and go to "Mail"
- Look in the Threading section (it depends on the language you have on your device), find the "Latest message at the top" switch and move it to the on position
- Exit the settings app and return to the mail application to see the new chronological order of appearance of your messages. You will now notice that the most recent messages are displayed at the top of the thread.
