-Notification Email
-========
-
-GitBucket can send email notification to users if this feature is enabled by an administrator.
-
-The timing of the notification are as follows:
-
-##### at the issue registration (new issue, new pull request)
-When a record is saved into the ```ISSUE``` table, GitBucket does the notification.
-
-##### at the comment registration
-Among the records in the ```ISSUE_COMMENT``` table, them to be counted as a comment (i.e. the record ```ACTION``` column value is "comment" or "close_comment" or "reopen_comment") are saved, GitBucket does the notification.
-
-##### at the status update (close, reopen, merge)
-When the ```CLOSED``` column value is updated, GitBucket does the notification.
-
-Notified users are as follows:
-
-* individual repository's owner
-* group members of group repository
-* collaborators
-* participants
-
-However, the person performing the operation is excluded from the notification.
