DTOO224 - Recipients of sent email must be unable to be added to the safe senders list.

Information

Users could send email messages to request that they be taken off a mailing list. If the email recipient is then automatically added to the Safe Senders List, future e mail messages from that address will no longer be sent to the users Junk email folder, even if it would otherwise be considered junk.
By default, recipients of outgoing messages are not added automatically to individual users' Safe Senders Lists. However, users can change this configuration in the Outlook user interface.

Solution

Set the policy value for User Configuration -> Administrative Templates -> Microsoft Outlook 2013 -> Outlook Options -> Preferences -> Junk E-mail 'Add e-mail recipients to users' Safe Senders Lists' to 'Disabled'.
