I have had the free version of ZA on my home computer for years and I absolutely love this program.

Where I work, a very small non-profit, we receive a large amount of spam (at least 50-75 a day) even though we subscribe to Spamfighter.

I would like to propose that we switch to ZA. However, I was told whatever I propose must work with Windows Server 2003 Standard Edition since our PCs are networked from an off-site server.

If we can do it, what minimum system requirements should we have and what products would you recommend?

TIA
