Hi- I'm doing a migration from 2010 Server. I've got the 2013 servers installed and configured (1 CAS, MBX, 1 MBX). Mailflow is working as expected from 2010, with 2013 being the proxy for all inbound and outbound email. All users still on 2010 server.
Before the coexistence, before 2013 Server was introduced, Exchange SPAM protection (i.e. Content Filtering, Connection Filtering, Sender Filtering, etc.) was working well, with virtually no SPAM reaching my users' mailboxes.
As of now, TONS of SPAM is being delivered. I've ran the Install-AntispamAgents.ps1 on the 2013 Servers. I see that the settings configured for the 2010 Server also apply to the 2013 Servers.
So why so much SPAM and how do I get antispam to work in this environment. My colleague postulated that turning on InternalEmailEnabled for all the filters would need to be set. Any ideas?
Thanx
