We have Eset Smart Security 4 and Eset Mail Security 4 installed. Both work a treat and are good at blocking spam - EXCEPT if it is in Russian. We are being deluged with Russian spam and can find no way to filter it out. Even Outlook's Junk Mail filter, which is pretty good, lets it through. Any idea what to do? Server is Windows Server 2003 x64 with Exchange 2007.
