from notes about PHP mail() function:

Code: Select all

Return Values
Returns TRUE if the mail was successfully accepted for delivery, FALSE otherwise. 

It is important to note that just because the mail was accepted for delivery, it does NOT mean the mail will actually reach the intended destination. 

IMHO theris no proper way directly using PHP to check is that $to address exist and your mail delivery was successfull.
Generally when using bounce way right way to check is it accepted by remote server it is check your mailbox.
If that $to (mail addr) is not exist on remote mail server on that remote mail server will automatically reply to you:
Can't deliver your msg.bla bla bla + a lot of tonnes server info))

This is the reason why you will often see

if (mail($to,$subject,$message,$headers)) {
// This is where you would write success code, or call some kind of success function...
} else {
// This is where the mail function fails, and you should/could call some kind of failed function or something
