I want to disable all email from my development wiki, which has some real data in it. Users have been getting emails for changes to pages on their watchlist.
I have $wgEnableEmail = false as the last line of LocalSettings.php
Version: 1.23.0
Severity: normal
You have to set $wgEnotifWatchlist to false.
But on Special:Preferences the option is not shown, when wgEnableEmail is false, so there should not be send mails, when $wgEnableEmail is false and no need to set $wgEnotifWatchlist explicit. But $wgEnotifUserTalk seems to have the same issue.
Change 132348 had a related patch set uploaded by Withoutaname:
If is false, disable other email settings
Change 132348 merged by jenkins-bot:
If $wgEnableEmail is false, disable other email settings
