I want to disable emails to a particular (automated) user. To do this, I think I can set the user's email address to an empty value.
In the User's configuration, I can set the email address to an empty value and press Save, the Save appears to succeed, but the empty value is not saved. Opening the User's configuration again shows the full email address (username@domain). In the User's configuration, if I set the address to an empty value and press Apply, I get an empty error window.
In the System Configuration E-mail section, I have a default domain set. If I remove the default domain, I can set the user's email address to an empty value.
Since Jenkins does not allow me to set an empty email address when the default email domain is set, I would like the ability to somehow disable Jenkins emails for a particular user.
