The subject of the post says it all: I want to be able to send emails from AppEngine when it is running locally. As far as I understood from this post:
to send emails from Google appengine
I have to setup a mail server. Can anyone tells me some easy steps to install a mail server locally and use it with Google AppEngine?

OK, I found a good solution for this question. Basically, just install sendmail tool, then use the option --enabled_sendmail when calling dev_appserver.py. So here is what I did (I use Ubuntu):
sudo apt-get install sendmail
Then whenever I call dev_appserver.py, I call it like this:
~/google_appengine/dev_appserver.py --enable_sendmail --port=8081 ./appengine/
Notice the --enable_sendmail option.
I believe there can't be an easier solution than this :-)

Why do you want to send mail from AppEngine while running locally? If it's just for testing purposes, Python comes with a built-in SMTP server that will log to the console for you:
python -m smtpd -n -c DebuggingServer localhost:1025
