So, for a business that does not have a in-house mail server there is no ability to scan incoming mail or outgoing for that matter?
Because if you look at the mail policy it is capable of scanning pop/s smtp/s imap/s and according to the documents it is supposed to be a proxy.
Trouble is the proxy in Copernicus also requires a NAT rule.
my statement about the proxy was not 100% accurate, there is no transparent proxy as stated in another thread in this forum. The included proxy will require a script to change the browser (default port3128) access to it.
