Setup Exchange 2007/2010 and 2013 Whitelists.

Providing you have Enabled Exchange 2010 Anti Spam and Enabled Exchange 2013 Anti Spam the read on!

A white-list is a list of approved domains / servers that are allowed to send email to your domain no matter what they send – meaning it may have any content in the email that would normally be prohibited from entering your Exchange organization but it will still get through to the end users as these domains are whitelisted. This is useful if you want to guarantee that you always receive email from certain companies.If you would like to add a white-list to exchange 2007/2010  to bypass any spam filtering systems the follow the guide below on how to setup a white-list in exchange 2007 , exchange 2010 and now Exchange 2013.

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.

Whitelist a domain exchange 2013

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.

get-contentfilterconfig

To view more extensions to this command view the official Microsoft page http://technet.microsoft.com/en-us/library/aa996791.aspx

    Well, trouble is, what if you have many whitelisted domains, you must all of them write again, and add latest in the end, followin coma.
    Is it possible to have them in samo CSV file then add new bypassed domain in and use command like:
    Set-ContentFilterConfig -BypassedSenderDomains C:\WhiteList.csv

      Here is the domain part of. It also covers senders

      For domains:

      $list = (Get-ContentFilterConfig).BypassedSenderDomains
      $list.add(“domain.com”)
      Set-ContentFilterConfig -BypassedSenderDomains $list

      To remove an entry, use the following command(s):

      Set-ContentFilterConfig -BypassedSenderDomains @{Remove=”domain.com”}

    To add one ore more domains:
    Set-ContentFilterConfig -BypassedSenderDomains @{Add=””,””,…}

    To remove one or more domains:
    Set-ContentFilterConfig -BypassedSenderDomains @{Remove=””,””…}

    The same applies for mail-addresses. Just replace “-BypassedSenderDomains” by “BypassedSenders”
