Hi Guys, I'm using PHP with MySQL data to send a very important email to clients when they enter the recipients email address into the system. On the whole it works for ME, to either my yahoo email address or any of my own domains email addresses that I have, However, when my WIFE gets it it isn't HTML (Even though mine is) with outlook OR outlook express and my boss doesn't get it at ALL even at his yahoo address, so something is wrong with my script. Can anyone look at it please and let me know if anything is blazingly obvious that I've done wrong? As I said I can receive emails on any account I personally try, but my boss cannot and if it doesn't work for him it's basically not working in his eyes as it could be having the same issue with others. $MP = "sendmail -t"; $HT = "<html><body>"; $HT = "</body></html>"; $fd = popen($MP,"w"); fputs($fd,"MIME-Version: 1.0\r\n"); fputs($fd,"Content-type: text/html; charset=iso-8859-1\r\n"); fputs($fd, "To: $word\n"); fputs($fd, "From: $email\n"); fputs($fd, "Subject: $subject\n"); fputs($fd, "X-Mailer: PHP3\n"); fputs($fd, "From: $email\n"); fputs($fd, "Email: $email\n"); fputs($fd, "$messageheader"); // actually this is the message itself pclose($fd); Any help would be REALLY appreciated.
