Question

<?php

require 'PHPMailer-master/PHPMailerAutoload.php';
$mail = new PHPMailer();

$mail->SMTPDebug = 1;                               // Enable verbose debug output

$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp.mail.yahoo.com';  // Specify main and backup SMTP servers
$mail->SMTPSecure = "ssl";
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = 'myemail';                 // SMTP username
$mail->Password = 'mypass';                           // SMTP password
//  $mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 465;                                    // TCP port to connect to

$mail->From = 'myemail@yahoo.com';
$mail->FromName = 'abc';
$mail->addAddress('abc@abc.com');               // Name is optional


//$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.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

Message could not be sent.

Mailer Error: SMTP connect() failed. 

Answer 1

You should really read what the troubleshooting guide says - that's why the link to it is included in the error output. Set SMTPDebug = 2 so you can see what the server says and it will probably tell you what's wrong.
