Confluence can mask the email addresses of users to protect them from mail spammers.

This is done by a Confluence administrator and is configured through the Administration Console. The Confluence administrator has three options for email address privacy:

• 公開： メール アドレスは公開されます。
• マスク： メール アドレスは公開されますが、スパム ボットが取得しづらいような方法でマスクされます。
• Private: only Confluence administrators can see the email addresses.

For more information on setting these options, which are configured using the Administration Console, refer to User Email Visibility.
