App Engine can finally receive mail. [bonus: delete your app as well]

Being able to delete an app is huge too. I've been waiting for this from day 1.

Finally. Now, we just need wildcard subdomains...

AppEngine is pretty much awesome when you want to reduce web portal hosting costs. I am rewriting/augmenting a Rails web app in JRuby + Sinatra + DataMapper so it will run well on either Java AppEngine or one of my own servers using (C)Ruby. If my project gets a lot of users I would like to keep my costs down. (I usually deploy to Amazon AWS, but if you can live within the AppEngine restrictions, then AppEngine is even cheaper than Amazon.)<p>The ability of receiving email sounds good, but I usually only use this for new account verification - with AppEngine you can just use Google accounts.

If I want to get started with App Engine but I have no experience, not with online apps nor with Python but I really want to learn, where would you guys suggest I start?

(Warning: deleted app names <i>can never be reclaimed</i>.)

Receiving email, that's great. One question: Is this a simple thing to setup for yourself (outside of GAE)?<p>I'd been wanting to do something like this for a while, converting an email to e.g. JSON. But I haven't found too much info on the subject..

Does anyone know of a good alternative to app-engine-patch (<a href="http://code.google.com/p/app-engine-patch/" rel="nofollow">http://code.google.com/p/app-engine-patch/</a>) if you want to use Django to develop on GAE?

I wonder if GAE will ever offer SMS support, like an open gateway. That would be pretty awesome for what we're working on.

Wow, this was my #1 req, very happy.
