I have an exchange server on which I've created a receive connector that can only receive email from a single IP address.

Now I need to make this receive connector accept all email sent to it. No spam filtering, no SPF checking, nothing.

I can't seem to figure out how to disable the spam filtering for this one connector.

Any suggestions?

If you set the AuthMechanism to ExternalAuthoritative, it wil treat that IP as trusted and not apply anti-spam measures to it.

Hi,

Ms-Exch-Bypass-Anti-Spam: This permission allows the session to bypass anti-spam filtering.

We can use the following command to allow this particular Receive Connector to by-pass Exchange's Spam Filtering

Get-ReceiveConnector Connector Name | Add-ADPermission -User NT Authority\Anonymous Logon -AccessRights ExtendedRight -ExtendedRights ms-exch-bypass-anti-spam
