I'm not sure what clients you will be running this with, but I have a site that has about 30 machines that send faxes out and they of course use Windows XP. I've set them up with Hylafax and I'm extremely happy with it. I don't have them doing it from email, rather I have a plugin that integrates with Outlook for their address book and they print to the fax printer. The server sends about 200 faxes a week, and I don't think that any have failed when the number is put in correctly. -- -=/>Thom
