Integration of Network Prevent for Email with Microsoft Exchange 2013 in Reflect Mode

Hello everyone,

I have been trying to integrate DLP NW Prevent for Email with MS Exchange 2013 in reflect mode. 

I have been trying MTA Integration Guide but it just gives a theoritical overwiew of the implementation. And doesn't shed light how Exchange will reat when it recieves email back from DLP. Email loop is likely to occur.

Can anyone help me with issue?

Thanks.

Atif
