//Mail Send Code 


$ToEmail = 'admin@gmail.com'; 
$EmailSubject = 'Site contact form';

//SMTP needs accurate times, and the PHP time zone MUST be set 
//This should be done in your php.ini, but this is how to do it if you don'thave access to that date_default_timezone_set('Etc/UTC'); 
     require 'PHPMailer-master/PHPMailerAutoload.php'; 
     //Create a new PHPMailer instance 
    $mail = new PHPMailer; 
    //Tell PHPMailer to use SMTP 
    $mail->isSMTP(); 
    //Enable SMTP debugging // 0 = off (for production use) 
    $mail->SMTPDebug = 0; 
//Ask for HTML-friendly debug output 
    $mail->Debugoutput = 'html'; 
//Set the hostname of the mail server 
    $mail->Host = 'smtp.gmail.com'; 
    //Set the SMTP port number - 587 for authenticated TLS, a.k.a. RFC4409 SMTP submission 
      $mail->Port = 465; 
    //Set the encryption system to use - ssl (deprecated) or tls 
     $mail->SMTPSecure = 'ssl'; 
    //Whether to use SMTP authentication 
    $mail->SMTPAuth = true; 
//Username to use for SMTP authentication - use full email address for gmail 
     $mail->Username = "username@gmail.com";//"lino.cspace@gmail.com"; 
    //Password to use for SMTP authentication 
    $mail->Password = "yourpassword";//"lino@123";

启用SMTP调试

$mail->SMTPDebug = 1; 

OR

$mail->SMTPDebug = 2; 

然后错误info会给你更多关于错误的信息

if (!$mail->Send()) 
{ 
    echo "Mailer Error: " . $mail->ErrorInfo; 
} 
else 
{ 
    echo "Message sent!<br>"; 
}
