  • Dear Sathish,

    Mail Transport rule will help you for achive your requirement

    Mail transport rule:

        Apply this rule if: Recipient is a member of "DL"

     Do the following: Reject the message or Delete message...

     Except if: The sender domain is "domain.com"

    Accept messages from Aricent & Altran 

    and Enable: Require that all senders are authenticated.

  • Hello,

    Instead of creating an ETR for the same, you mat block the external mailflow from the DL settings itself from Exchange EAC GUI:

    Also, I will suggest to perform the change from AD attribute end with the help of EMS:

    Set-DistributionGroup -Identity <Name of the DL> -RequireSenderAuthenticationEnabled $true

    This will block all external mails to the said DL. Please check from your end and let me know if it fixes the issue.

    Thanks and regards,

    Abhishek Mukherjee
