**Description**
If a user has verified their email address on Wikimedia, by default the preference to receive emails from other users is enabled. While this can be a productive tool to communicate it is also a big vector for harassment because this communication is not transparent and available on wiki for administrator's to witness.
The current preference is all or nothing — either all users can send emails, or no users can send emails. As a target of harassment, I want to prevent certain users from sending me email.

**Scenario**
User:Apples mutes User:Bananas
**Acceptance criteria**
* On the 'User profile' tab of Special:Preferences, under the 'Email options' section a box similar to the Echo Mute box should appear, allowing users to prevent other users from sending them direct emails
* Final copy TBD
* This first version will be a local Mute list only
* Bananas should not see the "Email this user" link in the left rail on User:Apples or other userspace pages
* If Bananas directly navigates to Special:EmailUser/Apples they should see the standard error message of "[[ https://commons.wikimedia.org/wiki/File:Special-EmailUser_screenshot_if_the_feature_is_disabled_by_a_user.png | This user has chosen not to receive email from other users ]]" as if Apples had the entire preference disabled:
