Hello, no we do not have any other spam filter server or appliance, just Forefront. For the most part, Forefront is doing a good job. It just seems to not be working for one specific tenant domain in the Exchange environment.

Nobody else suggested the solution, this tenant just wasn't correctly setup.

Hello, <br />
<br />
We have a multi-tenant Exchange 2010 environment with Forefront Protection 2010. One specific tenant is getting quite a bit of spam. When checking forefront, it seems that no external mail coming in gets blocked for them, but internal mail does. This tenant is setup via a Windows 2012 Web Application proxy server, where we have another tenant as well. All others are on TMG, but will soon also move to the web proxy server as well.<br />
<br />
I am not sure why this specific tenant seems to bypass the spam filter. Any help would be appreciated.<br />
<br />
Thank you

Microsoft Forefront, formerly known as Internet Security and Acceleration Server (ISA Server), is a network router, firewall, antivirus program, VPN server and web cache that runs on Windows servers. It includes identity management and protection systems, and discontinued systems for threat management and network protection, along with protection for Sharepoint and Exchange. The scope of discussions includes forward and reverse proxy, application and service publishing, virtual private networks (VPNs), outbound access rules, SSL certificates and network routing within either a single node or an highly-available array pairing.

Various techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) vs. not rejecting all spam (false negatives) - and the associated costs in time and effort. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials.
