Change Mail’s retention policy for deleted messages
Apple Mail seems to permanently (again) delete emails from the Deleted Messages folder in seven days on the iPhone/iPad; it is customizable on the Mac. is there a way to change this? Seven days is way too short.
Mail on the iPhone used to allow some level of customization for retention policy in the past, although I’m unaware of when it changed (and, hence, lost a bunch of emails).
iPhone XR, iOS 15
