What is the incoming email address used on google-app-engine?

I'm reading this article : http://code.google.com/intl/zh-CN/appengine/docs/python/mail/receivingmail.html

I'd like to know, is this the right article to read to deal with mail from others sent to me ?

My Gmail is zjm1126@gmail.com, so when someone sends email to zjm1126@gmail.com, can I do something automatically with the incoming mail?

Update:

The article say:

Your app can receive email at addresses of the following form:

string@appid.appspotmail开发者_开发问答.com

Where do I set this?
