There are some strange quirks I noticed while working extensively with Google App Engine. These include: 1. You can not send HTML messages using mail.send() without doing some extensive work arounds. 2. You can not send html messages from GAE from any address apart from your Gmail address, although the documentation states that you should be able to do so with any address that you can also use to login to the app engine control panel, this isnt so.
Has anyone noticed any more? --
