SMTP local server in windows 7? (running IIS7)

This response is a little late, but might help the next person…
No, Windows 7 does not come with an SMTP server. Supposedly Remote Server Administration tools includes an SMTP server, but according to this link, it does not work.
Some options for sending email from a Windows 7 machine are:
For development purposes, I like smtp4dev http://smtp4dev.codeplex.com/. It is open source and emulates a SMTP server. However instead of actually sending the email, it keeps in in an app on the system tray. Great for making sure you don’t accidentally SPAM your users.
If you are planning to send emails out for real, I would advise using a SMTP server with a static IP address as most spam filters dislike dynamic addresses and will block the email.
I have not used it, but if you must send email from your local Windows machine and am not worried about SPAM filters, Free SMTP Server from http://www.softstack.com seems pretty popular.
