Email piping class-script

[eluser]CARP[/eluser]
Hi
I'm developing a mini-tickets system with CI
Now I need to implement an email piping module, that allows users to work with this tickets system through their mobile phones just by writing/replying emails

Does any1 know about a simple email piping class/library (free/paid) I could download then convert to CI?

Thanks a lot in advance,
