Every new operating system comes with exciting new features, although it can also come with unexpected problems. For example, iOS 16 included several interesting changes regarding the issue of notifications, but unfortunately it has a severe bug that someone can take advantage of to break down the mail app.
The VPN Tracker site made a blog post where it reported that there is an extremely simple way in which someone with bad intentions can crash the iOS 16 Mail app indefinitely. Basically, all they have to do is use a few symbols as the sender.
According to the publication, most emails arrive with such a sender:
However, several staff members received a spam email whose sender came from:
“”@ejemplo.com ; with quotation marks at the beginning.
Basically, when a person with iOS 16 receives an email with those characters, the application enters a crash loop from which it cannot escape: because the received email is the first thing shown when opening the app, the app closes automatically.
According to VPN Tracker, the only way to end this error is to enter your email from a different device (that does not use iOS 16) and delete it, so that it no longer appears in the inbox. This way, when you open the app from your iPhone, it will stop crashing.
So far Apple has not commented on this, but it is likely that it is already working on a solution for this error, as it always does. In the meantime, just watch out for junk emails.
