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 domain.com,domain2.com

   To whitelist against SPF filtering:

   Set-SenderIDConfig -BypassedSenderDomains domain.com,domain2.com

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.
