Some Jazz components use e-mail to communicate with users. By default, e-mail notifications are not enabled. To enable e-mail notification, select "Enabled" from the drop down box, set the e-mail configuration properties, and optionally select which set of users should receive e-mails (by default all users receive e-mail).
E-mail notifications can be sent to all recipients or to a specified group of recipients. To send e-mail to a subset of the users, you can specify that e-mail notifications are restricted to e-mails mathcing a whitelist filter.
