When sending text massages using php mail function, is it possible to alter the sender address? It works fine when sending. an email. Even withing the same message however when receiving a text message the sender is the name of the servers the message originated on. Is this done by the cell phone provide? If so, is there any work around? or even a service company out there allowing you to use your domain to send sms text messages therefore you can receive messages as the individual replies. I know you can probably do this through google voice but I would rather do something personalized to each domain.
