Any way to detect SMS to E-Mail Gateways?

Question

I want to create a PHP app that can send text messages ; There are different gateways for different email carriers.

Is there any library I could use that would be able to lookup or detect which gateway to use just by passing the phone number into it? This way I can take whatever email address I get out and use PHP's email functions to send a message.

Answer 1

There are companies that provide a lookup service, but it's generally not free (for example, we've used mBlox for this). There's no simple algorithm you can use, either, because of number porting and so on.
