Exchange 2013 and Forefront Protection
Posted on 2013-11-07
I have an Exchange 2013 Installation all in one server . Also i have setup an Edge role for this Exchange installation. In the Edge server i installa forefront protection for exchange for antispaming.
I have a very strange problem. I have a specific user that can't receive email from a specific domain . In edge roles i see 5.1.0 Sender denied,0,1,, .
I have manually add the whole sender domain to forefront white lists but i get the same sender denied error.
Any ideas ?
