PHPMailer not working: Message could not be sent

I am trying to create a contact form on my website using PHPMailer. I am having some trouble setting it up. I am trying to use G-mail as my smtp host. I was wondering if anyone can help troubleshoot this? This is my mailer code: ``` <?php require("class.phpmailer.php"); require("class.smtp.php"); $mail = new PHPMailer(); $mail->IsSMTP(); $mail->SMTPAuth = true; // turn on SMTP authentication $mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for GMail $mail->Host = 'smtp.gmail.com'; $mail->Port = 467; $mail->Username = "validmail@gmail.com"; // SMTP username $mail->Password = "workingpassword"; // SMTP password $mail->From = "validmail@gmail.com"; $mail->FromName = "Mailer"; $mail->AddAddress("josh@example.net", "Josh Adams"); $mail->AddAddress("ellen@example.com"); // name is optional $mail->AddReplyTo("info@example.com", "Information"); $mail->WordWrap = 50; // set word wrap to 50 characters // $mail->AddAttachment("/var/tmp/file.tar.gz"); // add attachments // $mail->AddAttachment("/tmp/image.jpg", "new.jpg"); // optional name $mail->IsHTML(true); // set email format to HTML $mail->Subject = "Here is the subject"; $mail->Body = "This is the HTML message body <b>in bold!</b>"; $mail->AltBody = "This is the body in plain text for non-HTML mail clients"; if(!$mail->Send()) { echo "Message could not be sent. <p>"; echo "Mailer Error: " . $mail->ErrorInfo; exit; } echo "Message has been sent"; ?> ``` The error message: ``` Message could not be sent. Mailer Error: The following From address failed: validmail@gmail.com ```
