To the OP what has GFI Mail Essentials been like for you cons/pros wise? I was looking at it a while back, but never got around to trying it. I've used the GFI Vipre AV and found it to be satisfactory enough at keeping malware out of a clean system, but absolutely awful at cleansing systems post infection, in fact i've lost a mail store due to it's 'remedial' actions in the past and i've never forgiven it since, so i'm little dubious as to GFI products to be honest.
