There are situations when we need to have user accounts in JIRA/ Confluence used only for mass mailing. We create a user account with a generic username and a mailing list address, for example user is 'my-list' and email is 'my-list@example.com', and then subscribe to the updates/ filters using that account. Or else, add that account as a watcher.
For security reasons, this user must not be able to log in and also must not be able to reset the password through Crowd. Disabling the account won't work because user won't receive e-mail when disabled.
Is there any user attribute that Crowd administrators can manually set so that user won't be able to log in?
