Is there any way to set the priority of PHP mail()? I looked at the online manual but I can't find any reference to it.
By priority, I mean High, Normal, Low or 1, 2, 3 in the headers. So the recipient knows the urgency of the mail.
Thank you!
Call it with the X-Priority header in the 4th parameter:
mail ( $to, $subject, $message , "X-Priority: 1")
