Journaling Rules using dynamic distribution groups

Journaling Rules using dynamic distribution groups

If you are configuring Journaling on an Exchange environment and not all domains are being managed by Mailsphere you can use Dynamic Distribution Groups to select the Organisation that are being managed by Mailsphere.  If you then add this Dynamic Distribution Group to the Journal rule it will only create Journal emails for the users that are part of the distribution group and it will not send journal emails for other organisations that are not managed by Mailsphere.
