Whatmail is a stand-alone (cgi) contact-form written in Python. It has the following features:
- Supports Unicode international characters (למשל עברית)
- Has recaptcha spambot protection
- Fully skinnable with mustache templates (so you can easily make it look like the rest of the site)
- Can gpg-encrypt the mail it sends (only makes sense if the form is served via SSL)
The code is here. You can see it in action (and send me something secret) here.
