Exchange Server 2013 uses delivery status notifications (DSN) to provide non-delivery reports (NDRs) and other status messages to message senders
All NDRs Generated from the server can be forwarded to a mailbox so that you can watch over internal NDR’s and External NDR’s to be proactive from getting blacklisted.
Also it helps to be proactive to get in touch with internal users when they struggle with NDR’s
Note : It can be forwarded only to a Mailbox – Not to a Distribution Group – It cannot be forwarded to a Distribution Group from Postmaster mailbox as well.
Step 1 :
First Login to ECP – Create a Mailbox with your primary address – Postmaster@testcareexchange.biz
Make your Display Name only PostMaster
Note – Make sure you have a good amount of mailbox size. otherwise once its full . It will stop receiving NDR emails
Step 2 :
By Default External PostMaster Address will be Empty
To Catch all External NDR’s (Common Scenario – When a mail is sent to a User from external world which doesn’t exist in our Server)
Set-TransportConfig -ExternalPostmasterAddress postmaster@testcareexchange.biz
Step 3 :
To Catch All internal NDR’s (Common Scenario – When a mail is sent to a Internal User to a internal User which doesn’t exist in our Server)
Set-OrganizationConfig -MicrosoftExchangeRecipientReplyRecipient Postmaster@testcareexchange.biz
Step 4 :
To Set What all the NDR’s you want to catch from the server. –
-5.1.1 – am specifically adding as we are doing a GAL sync in my scenario and deleting/recreating users often so i want to catch all NDR’s which says (User Doesn’t exist)
Run (These are list of Common NDR’s)
Set-TransportConfig -GenerateCopyOfDSNFor 5.4.8,5.4.6,5.4.4,5.2.4,5.2.0,5.1.4,5.1.1
To See Common Enhanced Codes (DSN Codes)
For Example
To Remove or ADD DSN Codes later
Set-TransportConfig -GenerateCopyOfDSNFor @{Add=”5.7.5″; Remove=”5.7.1″}
Only to Add
Set-TransportConfig -GenerateCopyOfDSNFor @{Add=”5.7.1″}
(DSN- Delivery Status Notifications)
(NDR-Non-Delivery Report)
Step 5:
Now I added the postmaster account in my outlook . It started collecting my NDR’s
