Create A Whitelist in Exchange 2007,2010 or Exchange 2013

This is a nice simple process.

1) First we need to run the exchange 2007,2010 or Exchange 2013 powershell (EMS ).

Once in there we need to run the following command

Set-ContentFilterConfig -BypassedSenderDomains the domain.com

That command will allow the domain “domain.com” to send emails into your Exchange organization regardless of any content or attachemnts.As you can I have whitelisted Microsoft.com on my domain.

To allow multiple domains you would need to do the following

Set-ContentFilterConfig -BypassedSenderDomains Nevilleuk.com,anotherdomain.com,andanotherdomain.com

You ca add as many or as few domains to that list as you require.

Finally to view what domains you have actually whitelisted then the command is as below

get-ContentFilterConfig

As you can see, we have only allowed Microsoft.com to be whitelisted here.
