[Eug-lug] IMAP mail monitor script

[Dave Compton]

Here's a little python script that I wrote to monitor my IMAP mail
inbox.  It works by checking periodically to see if any new unread
messages have appeared.  I use upstart on an Ubuntu 8.04 server to keep
it running all the time.

In my case, I'm using the script to pass the new e-mail on to myself as
a cell phone text message.

The script is pasted in below and also in github:
