Question

I am using php mailer class. I am getting :
SMTP Error: The following recipients failed: [e-mail]

$mail = new phpMailer();
$body             = "Hello, this is a test mail.";
//$body             = preg_replace('/\\\\/','', $body); //Strip backslashes

$mail->IsSMTP();                           // tell the class to use SMTP
//$mail->SMTPAuth   = true;                  // enable SMTP authentication
//$mail->Port       = 25;                    // set the SMTP server port
$mail->Host       = "localhost";           // SMTP server
$mail->Username   = "localhost";     // SMTP server username
$mail->Password   = "password";            // SMTP server password
//$mail->SMTPSecure   = "tls";
//$mail->IsSendmail();  // tell the class to use Sendmail

$mail->AddReplyTo("[e-mail]","First Last");

$mail->From       = "[e-mail]";
$mail->FromName   = "First Last";

$to = "[e-mail]";

$mail->AddAddress($to);

$mail->Subject  = "First PHPMailer Message";

$mail->AltBody    = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test
$mail->WordWrap   = 80; // set word wrap

$mail->MsgHTML($body);

$mail->IsHTML(true); // send as HTML

if($mail->Send()){
    echo 'Message has been sent.';
    }

What can be the reason ?

Answer 1

I had this problem using authenticated SMTP. When I tested my mailing from home using xampp but connected to a (shared) server, emails went to users without problems. When I tried the same thing with the PHP on the host server, emails went through to addresses on my account but NOT to external addresses. (Ie. if my address is [e-mail] and I send an email to [e-mail], it goes through but if I send it to [e-mail], it fails) The solution turned out to be to use the full host address when working on my local pc, ie $mail->Host = “mail.fred.bloggs.com”, but $mail->Host = “localhost” on the server. May seem perverse but it works.
