hello, i have an iphone 3g and can successfully send text messages using the PHP mail() function. My issue is that for each message i receive, the "telephone number" associated with the incoming text message changes each time. If possible, I would like to somehow make this number constant so that I can take advantage of iphone's ability to aggregate all text messages from the same telephone number -Otherwise my iphone would be cluttered with messages. Is there a way to do this?

an example of the numbers I receive would be 1(410) 000-001, 1(410) 000-002, 1(410) 000-003, etc... can i make this constant somehow?

$message = stripslashes("new user just joined!");

mail("[email protected]", "Subject", "$message");

please let me know! thanks...
