I hate to say this but I'm completely against e-mailing from the workplace! I would not dream of mixing up my private affairs with the firm's. I would recommend getting an iMac and doing the business at home. Then it's etirely your own business.
Even my daughter who is a software engineer never does he e-mailing from the workplace...

Apart from the broadside that I'm expecting, I think you are great forummers on a brilliantly run forum.

Be nice
