I always use the mail manager Email from Apple. It is clear that it is a fairly simple email client, and that there are a few applications in the App Store with many more functions and attractive features that help you manage your messages, but for my cousin security is much more than other things.
I do not like to enter the credentials of my email accounts in third-party applications, and that they manage my incoming and outgoing messages. Mail is a very simple manager, but it is from Apple. Today we learned that the famous mail application Edison Mail, you have had a code error and some email accounts have been crossed between different users. Big mistake.
Customers of the popular email application Edison Mail had a busy day yesterday. Several users of such software reported yesterday that they can view other users' email accounts within the app for macOS and iOS. In what appears to be a major privacy violation, those affected are reporting that after enabling a new sync feature, have full access other email accounts of unknown users. A very serious mistake for a mail manager.
@edison_apps Guys, I see strangers' e-mail in my app after you added sync features. I can see their email, so they can probably see mine. Despite what your blog post says I CANNOT change my sync account and all I can do is block myself and them from ever using the app. Clusterf *.

Edison recently implemented a new synchronization to allow connected email accounts to show on all of your devices, but clearly something has gone significantly wrong in said update.
Several users have also reported that they have received the notice that other devices are linked to your accounts, indicating that other users are able to view your emails.
We are urgently working to resolve this technical problem in Edison Mail. Yesterday a software update rolled out to a small percent of our users. We have reverted that now and are reaching out to users who have been impacted as fast as we can.

Edison has started responding to users on Twitter stating that the company is "working urgently to solve this technical problem ”and has reversed the change that introduced the problem for a“ small percentage of our users ”.
