SMTP is not included in Vista or Windows 7. The IIS 6.0 Manager shipped with Windows 7 is not aimed for IIS 7.5 Management. To manage IIS 7.5/FTP 7.5 shipped with Windows 7, you must use IIS 7 Manager.
You have three options if you want SMTP support, so Symphony can email directly from the server:
• Use a server operating system and you then use the Microsoft supplied SMTP server.
• Use Windows 7 but use an external email gateway. For example, if the Symphony server is on the office LAN with a local email server, Symphony can relay through that server.
• Install a 3rd party SMTP server that works with Windows 7.
