Check the Release Notes on TMG Beta 2 Limitations to E-mail Policy Configuration
In the E-mail Policy node you can configure Forefront TMG to inspect inbound and outbound email traffic using the E-mail Protection wizard. You can also configure the advanced Antispam and Antimalware settings and Content Filtering rules. Mail inspection functionality is implemented by Exchange Edge and Forefront Security for Exchange components, integrated into and managed by Forefront TMG.
- You cannot configure IP Block List Providers or IP Allow List Providers in Forefront TMG Management.
- Setting authentication for Server-To-Server connections and subscribing the Exchange Edge servers to internal Exchange Hub servers do not function in this version.
- Forefront Security for Exchange (FSE) Antispam and Malware updates are not configurable through Forefront TMG, but you can configure them in the FSE administration console or in the Exchange management console.
Warning: Do not subscribe Exchange Edge to internal hub servers manually, as this will cause your configuration to fail.”
