The official DOPP SDK Archive DOPPSDK_1.0.zip does not contain the DOPPenable.exe, but only a DOPPenable.txt with the following content:
Microsoft Forefront Protection for Exchange Server removed a file since it was found to match a filter.
File name: "winmail.dat->DOPPSDK_1.0.zip->DOPPenable.exe"
Filter name: "FILE FILTER= AMD Delete: *"
I've used the "EnableDOPP.exe" attached in some forum post here.
thanks for reporting this problem. We will update the package. In the meantime, please find the DOPPEnable.exe attached.
(.exe file now removed, problem fixed!)
The download is now fixed, and I have removed the .exe from Chris's post, to avoid confusion. Please get the download from the website.
THANKS for reporting it.
