Functional account not receiving Emails
Posted by Muhammad Ahmed, Last modified by David Szoke on 25 April 2018 09:53 PM

Issue : Emails sent inbound to a distribution list are showing delivered within Proofpoint Essentials but not reaching the distribution list.

Resolution : Within exchange under the Distribution list properties there is a parameter that needs to be modified so that external Emails can be received.

Follow these steps :

                              1. Go to the distribution list's Properties.

                              2. Click on the Mail Flow Settings tab.

                             3. Double-click Message Delivery Restrictions.

                              4. Uncheck the box "Require that all senders are authenticated."

Please contact Microsoft for any further information.
