Exchange Server Whitelisting

To effectively whitelist email from a certain domain requires several commands, to cover the various reasons why email may be blocked.

  1. Open Exchange Management Shell.

  2. Enter:

    To whitelist against content filtering:

    Set-ContentFilterConfig -BypassedSenderDomains,

    To whitelist against 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.
