    503 No valid recipients specified error when using 'to' header

    The following works fine: (PHP)

    mail("newuser@localhost.com", "Subject", "Body", "From: Admin@localhost.com\n");

     When I move the 'to' email to the headers:

    mail("", "Subject", "Body", "From: Admin@localhost.com\nTo: newuser@localhost.com\n");

     I get the error "503 No valid recipients specified"

     This normally works, is there a reason for this to be interpretted differently?
