Exchange Server Allow Lists

To ensure email from certain domains are delivered reliably requires several commands, to cover the various reasons why email may be blocked.

  1. Open Exchange Management Shell.

  2. Enter:

    To bypass content filtering:

    Set-ContentFilterConfig -BypassedSenderDomains,

    To bypass SPF filtering:

    Set-SenderIDConfig -BypassedSenderDomains,

Note these commands overwrite the existing settings so to add further domains they must all be included in the single command. Keep a text file containing the commands so they can be added to easily.
