Exchange 2013 Initial Configuration Settings: How to configure a Postmaster address (part 8)

Exchange 2013 logo

In this post I’ll look at how to configure a postmaster address for our Exchange Organisation.

The postmaster address is used for non-delivery reports (NDRs) sent to recipients outside of your Exchange Organisation and is specified in RFC 2821.

In Exchange 2013 the external postmaster address is blank by default. This has the effect of the external postmaster address being postmaster@YourDefaultAcceptedDomain.

It can be useful to create a postmaster mailbox, or assign the email address to an admin mailbox so that recipients can reply to NDR messages for assistance. Anyone who is familiar with NDRs will appreciate they are far more useful to admins than they are to end users! The downside of this though is as it’s a well known address it can be open to abuse and spam.

Exchange Admin Center

1. In the Exchange admin center (https://localhost/ecp) click mail flow on the left hand side, and then click receive connectors, then click the more options …,  then select Organizational transport settings.

Exchange 2013 - mail flow - receive connector - more settings - organizational transport settings

2. Select delivery in the left hand menu, and then enter yout external postmaster address and click save.

Exchange 2013 - organizational transport settings - delivery - external postmaster address3. So with the postmaster address now configured, you have the option of creating a mailbox for it, assigning it to an existing mailbox, or not configuring it at all.




Exchange Management Shell

To perform the same tasks in the Exchange Management Shell we’ll use Get-TransportConfig and Set-TransportConfig.

1. First type Get-TransportConfig | fl

Get-TransportConfig format-listAs you can see the ExternalPostmasterAddress is blank.

2. Type Set-TransportConfig -ExternalPostmasterAddress postmaster@oxfordsbsguy.com

Set-TransportConfig -ExternalPostmasterAddress

3. We’ll now check is has set with the following command:

Get-TransportConfig | fl ExternalPostmasterAddress

Get-TransportConfig format-list ExternalPostmasterAddress4. So with the postmaster address now configured, you have the option of creating a mailbox for it or assigning it to an existing mailbox, or not configuring it at all.
