Setting several postmaster adresses for each individual domain

David DELHOMME 21 Reputation points


My company uses several domain (like :,, and we would like to set up a specific external postmaster adress for each one of those domains.

We're running on an Exhange Server 2010.

Is there a way to do this ?

I've seen several subjects on this but didn't find any clear answer...

    Hi @David DELHOMME

    From your description, I suppose you would like to change the email address which sends system-generated messages, for example NDR messages.
    The cmdlet is as you mentioned: Set-TransportConfig -ExternalPostmasterAddress postmaster@Company portal .com.

    However, you can only configure one postmaster address.
    It is not possible to configure multiple addresses for each domain.

    There are some threads asking the same question.
    For your reference:
    Postmaster when exchange hosts multiple domains
    Postmaster address for multiple smtp domain

    Sure thing.

    First Create the mailbox: ( I dont have 2010 around anymore, so here are some links)

    Then add those email addresses to it:

    Scroll down to:
    Add additional email addresses using the EMC in Exchange 2010 and Exchange 2007


    then give yourself full access to mailbox!

    Hi @Kael Yao-MSFT

    Yes that's exactly what i would like to do !

    Is it something not possible because of the version of my Exchange Server (2010) or even with the latest one it's still not possible ?

    Do you know if there are any other way to do this even if it's not an "official" one ?

    Yes i did check these links before posting my question but there wasn't a clear answer like yours haha

    Thanks for your help !
