Hi,
we're running MS Exchange 2010 inside a VMWare virtual machine with 6 GB of RAM, which is admittedly tight. about 50 Mailboxes running on it, of which are about 10 heavy-duty (> 10GB Mailbox Size, lots of mails).
We're about to install Mail Security on the productive server.
Before doing so, I want to be certain about the negative effects on performance Mail Security will cause. Are there any? If yes, will it affect CPU or rather RAM?
