Confluence can mask the email addresses of users to protect them from mail spammers.
- Public: email addresses are displayed publicly.
- Masked: email addresses are still displayed publicly, but masked in such a way to make it harder for spam-bots to harvest them.
- Private: only Confluence administrators can see the email addresses.
For more information on setting these options, which are configured via the Administration Console, refer to User Email Visibility.
Take me back to the Confluence User Guide.
