[Blind-sysadmins] MS Forefront Protection for Exchange

I seem to be drawing a complete blank finding anyone who knows anything about Microsoft Forefront Protection for Exchange Server. Do any of you guys know anything at all about it? ESET is due a hefty fee for renewal soon, and at $1 per month, per user, this appears to be a decent solution. BTW, it's taken since the New Year, but we look like having resolved our SBS 2010 performance issues. It seems that the Exchange 2010 part did not like having one Outlook 2003 client for a short period early on, and messed up the RPC binding order. Just a pity that the error reports didn't point in that direction. George.
