I'm looking to implement a "Contact Us" form with Cherrypy and was wondering: Is there a good recipe (or a BSD licensed set of code) that I could use instead of reinventing the wheel?
Ideally, this would be Cherrpy 3.1 compatible.
Well, I had to look into a solution. This works (ugly, and w/o Javascript validation) -- using the smtplib lib. Also, note that I stole Jeff's captcha for this example. Anyone using this will need to change it.
EDIT: I added validation.
