Need clarification regrading below setting option which appears while adding users in Jira.

"Allow any accounts using these email domains to join your site, you can edit these settings any time"

Hi Rishabh - Welcome to the Atlassian Community!

Basically that means that any user with an email address with that domain can join your Jira instance without having to be invited first. 

For example, if your domain was jira.com then any user with an email like rishabh@jira.com or john@jira.com would join without having to be invited first.

Hi there. I'm trying to turn off having this checkbox even appear on the user invite page. We accidentally checked the box once and then had a panic. I went to admin.atlassian.com and under Site Access, chose Don't Approve Any Domain, but the little checkbox still appears on the user invite page. Shouldn't it go away? Thanks.
