Why print PHP mimeheader mail messages to the screen after sending?

Question

Here is the problem, I just implemented PHPMailer and print the Mime Header to the screen after sending the email. I use the latest PHPMailer code specified in GITHUB and I went through almost everything, but I can not find the reason why it prints on the screen. Let me know if you need more information. I don't seem to think about anything else. See below:

Here is the implementation code:

 require("class.phpmailer.php"); $mail = new PHPMailer; $mail->From = ' [e-mail] '; $mail->FromName = 'xxxxxxx xxxxx'; $mail->addAddress($email, $fname); $mail->addReplyTo('', ''); $mail->IsSMTP(); $mail->SMTPDebug = 1; $mail->SMTPAuth = true; $mail->SMTPSecure = 'ssl'; $mail->Host = "smtpout.secureserver.net "; $mail->Port = 465; $mail->Username = " [e-mail] "; $mail->Password = "password"; $mail->WordWrap = 50; $mail->isHTML(true); $mail->Subject = 'xxxxxxx.com Confirmation'; $mail->Body = "This is the text body of the message, it is printed here. blah blah blah"; $mail->AltBody = "This is the alternate text body for non-html email that may or may no be reading this.<br />This is also the text body"; if(!$mail->send()) { echo 'Message could not be sent.'; echo 'Mailer Error: ' . $mail->ErrorInfo; exit; } 

Answer 1

You need to install

 $mail->SMTPDebug = false; 

Answer 2

Personally, I expected SMTPDebug to write to error_log, not an echo to the screen.

Add this to your PHPMailer configuration to enable this behavior:

 $mail->Debugoutput = 'error_log'; 

Fortunately, this is supported, not the default.
