Apple's new operating systems - OS X El Capitan and iOS 9 - were even overly helpful in terms of mail handling. When you type an E-Mail recipient, the system offers many options, which is absolutely unacceptable for busy people. How to solve a problem?

A logical option for many address hints is to offer only emails from Contacts. If you turn off the Contacts slider in your iOS mail settings, Apple will warn you that it will remove any “unconfirmed” email addresses, but unneeded contacts will still show up. Apple keeps them safe - even after reinstalling iOS from scratch, iCloud will gently transfer junk to your device.
Why did Tim Cook & Co. put such a pig on users? Blame the new feature in iOS 9 and El Capitan called Proactive. Based on your interests, it tries to find what you need - but, like any software, it refuses in the most unexpected place. In our case, Proactive crashes due to a large database of email addresses - it "sees" people with whom we actively communicated before, and thinks that we "forgot" about them, although in reality they are simply no longer needed, because correspondence on for one reason or another has already been interrupted.
To disable Proactive for the Mail app on iOS
1. Open Settings and select the Mail, Addresses, Calendars section;
2. Uncheck the box next to Events found in Mail;

To disable Proactive for mail on OS X
1. Open the Contacts app, select Settings in the menu bar;
2. Uncheck the box next to Show contacts found in Mail.


Follow this procedure on all your Apple devices.
The Mail app for OS X has a similar feature: it stores the addresses of all previous recipients in memory. This list is very convenient for both adding people to contacts and deleting unnecessary email addresses. To get to the list, open Mail, on the menu bar, click on Window and select Previous Recipients.
