Can anyone tell me if the SmarterMail Professional add-on you get for Plesk 7.5 for Windows is a standalone installer, with it's own license? I'd much prefer to run the mail on a seperate server to the web servers? If you do get a seperate installer and license, what are the limits on the domains and e-mail accounts? Directly through SmarterTools, their Pro version supports 30 domains and 250 users. Thanks in advance!
