Which Exchange protection to use?
We've currently got an Exchange 2003 server but have been getting massive amounts of spam recently.
The server has McAffee Groupshield installed, and also GFI MailEssentials (both installed before I started here).
When I started, I purchased Sophos including PureMessage.
My question is, should I remove the McAffee and GFI software and just use Sophos, or can PureMessage run alongside the others?
Also, if anybody has setup PureMessage before, how long and complicated is it, as I would want it up and running quite soon after install to keep us as protected as possible.
