Confirm Cell Phone Email

[bobbonew]

Hey guys. What i'm looking to do is add some mobile functionality on my site. What this means is, I want people to be able to interact with my site with their mobile phones.

How I want to accomplish this is through e-mail. Any cell phone can pretty much send texts, but instead of a number they can enter [e-mail]. Then for instance if they are on verizon wireless, I will recieve an email from

[10-digit phone number]@vtext.com

or if they are on AT+T:

[10-digit phone number]@txt.att.net

Now the problem is, you can spoof e-mails. So how do I make sure that these e-mails are legit? I'm assuming I would somehow have to extract header information from the e-mail and confirm the mail server where they are sent in php? Any suggestions to how I could do this? I know Twitter had a large problem in the past because they assumed all the e-mails were legit, and people started spoofing.

Thanks!

Confirm what? The email address? If so, you confirm the email address for a mobile the same way you would any other email address.
