send email from arduino

Hi, for a project I am trying to automate sending an email from the arduino dum. (like a conditionally based alert). the method I am currently trying, unsuccessfully, is to use telnet kind of commands but cant get that to work at all. Any other ideas of how I could send an email from the arduino and the Ethernet shield.

thanks for any help

Found on this forum - http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1235534880

Also read - Ethernet - Arduino Reference - for the meaning of the used commands.
