We don't have antispam agent installed on our hub servers. wE have 4 hub servers for load balancing. We upgraded our 2 hub servers from Windows 2000 to Windows 2008 and ever since our emails from internal applications are ending up in the junk -email.
If the antispam agent is not installed that means we are not content filtering right? What would cause this?
We are on Exchange 2007 SP3
Let me know if you need more information.
