Email, via RSS and on your mobile phone! Sure, why not. Actually the only downside that I can see here is the fact that its for Gmail users only.

What is it?
MobiGM is a small utility that periodically checks your GMail inbox, and sends updates to a mobile phone via email. Certainly, you could just set up a couple filters with GMail’s powerful filtering system to forward messages to your phone and be happy with that, but MobiGM allows you to dynamically react to what appears in your mailbox (which we will exploit in future projects).

Technologies used/Requirements:

* GMail / atom feeds
* PERL
o XML::Parser
o Net::SMTP
* cron
* Linux
* BASH
* wget

How does it work?
GMail users can subscribe to an atom feed that contains unread emails in their inbox. We will write a simple script to download the atom feed, parse it, figure out if any emails are new, and forward the new emails to our cell phone address. Note that there are still some pay-as-you-go cellphone providers that do not charge for receiving text messages (even from email), so this can be a very inexpensive way to keep track of your inbox on the go.

There is a lot of potential to add power to this application. With a little knowledge of PERL, you could create custom filters (including things impossible with GMail filters such as “only forward during xx hours of the day”) and reactions to receiving emails…. Source: Open-Source Fun
