Transmit Data using gprs from RCM3000

Can anybody give me an idea of how to transmit data from RCM3000 to a web server through email or any means(What are the AT Commands required). I came to know that if you send a mail to any inbox of yahoo or gmail, you can write some program on your desktop to retrieve the information from the inbox using POP3 or SMTP.

Can anyone through more light on the above requirement.
