Hi,
Strange question,
We have a users who intermittently cannot email another internal user. He gets the error
#554 5.1.0 Sender denied ##
I have ran Get-SenderFilterConfig and the person did not show in the list. I have checked the incidents on Forefront protection and non showed up.
Any other ideas what it could be ?
