Hi,
Does anyone know a way to set a receive connector to only request authentication in certain circumstances?
Let me explain the scenario: If you have a receive connector that is set to accept general inbound emails from anyone then it will be set to accept emails from any sender address.
However, if someone is trying to spoof the sender address and they use an email address which is valid within your organisation then it would be really useful if it could request authentication at that point, since emails from internal users should only come from authenticated devices.
Is there any way to do this?
Thanks in advance.
Neil
