Ok, I have an aging NT4/SP6 server with Exchange 5.5 SP4. I installed NOD32 2.5 with XMON solely to strip off cetain attachments like .exe/.bat/.rar etc. However I can send myself .bat files externally without a hitch. They just come right on through via Outlook and saveable on to my desktop! I am pretty sure I have configured the rules correctly or is there a known issue with NOD32 and my set-up? Any input appreciated.
