SMTP connect（）失败PHPmailer - PHP

Question

我是PHP的新手。我试图通过PHPmailer向自己发送一封示例电子邮件。我正在使用gmail的smtp服务器。我试图从我的Gmail帐户发送一个示例邮件到我的雅虎帐户。但我收到错误：Mailer Error: SMTP connect() failed. 这是代码：

<?php

require "class.phpmailer.php";
$mail = new PHPMailer(); 
$mail->IsSMTP();                              // send via SMTP
$mail->Host = "ssl://smtp.gmail.com";
$mail->SMTPAuth = true;                       // turn on SMTP authentication
$mail->Username = "[email protected]";        // SMTP username
$mail->Password = "mypassword";               // SMTP password
$webmaster_email = "[email protected]";       //Reply to this email ID
$email="[email protected]";                // Recipients email ID
$name="My Name";                              // Recipient's name
$mail->From = $webmaster_email;
$mail->Port = 465;
$mail->FromName = "My Name";
$mail->AddAddress($email,$name);
$mail->AddReplyTo($webmaster_email,"My Name");
$mail->WordWrap = 50;                         // set word wrap
$mail->IsHTML(true);                          // send as HTML
$mail->Subject = "subject";
$mail->Body = "Hi,
This is the HTML BODY ";                      //HTML Body 
$mail->AltBody = "This is the body when user views in plain text format"; //Text Body 

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

我在Windows 7 64位计算机上使用WAMP服务器。可能是什么问题？请帮我解决这个问题。谢谢！

Answer 1

您需要添加Host参数

$mail->Host = "ssl://smtp.gmail.com";

另外，检查您是否启用了open_ssl。

<?php
echo !extension_loaded('openssl')?"Not Available":"Available";

Answer 2

这个问题的解决方案非常简单。实际上Google开始为其用户使用新的授权机制..您可能在调试控制台中看到另一行提示您使用任何浏览器登录您的帐户。这是因为自2014年以来google开始使用的新XOAUTH2身份验证机制。记住..不要使用ssl over 465，而是使用tls over 587.这只是因为XOAUTH2身份验证机制。如果您使用超过465的ssl，您的请求将被退回。

你真正需要做的是..登录你的谷歌帐户并打开以下地址https://www.google.com/settings/security/lesssecureapps并检查开启。你必须这样做才能让你与谷歌SMTP连接，因为根据新的认证机制谷歌反弹所有那些不遵循任何标准加密技术的应用程序的所有请求..检查开启后..你很好go ..这是代码，对我来说很好..

require_once 'C:\xampp\htdocs\email\vendor\autoload.php';

define ('GUSER','[email protected]');
define ('GPWD','your password');


// make a separate file and include this file in that. call this function in that file.

function smtpmailer($to, $from, $from_name, $subject, $body) { 
    global $error;
    $mail = new PHPMailer();  // create a new object
    $mail->IsSMTP(); // enable SMTP
    $mail->SMTPDebug = 2;  // debugging: 1 = errors and messages, 2 = messages only
    $mail->SMTPAuth = true;  // authentication enabled
    $mail->SMTPSecure = 'tls'; // secure transfer enabled REQUIRED for GMail
    $mail->SMTPAutoTLS = false;
    $mail->Host = 'smtp.gmail.com';
    $mail->Port = 587;

    $mail->Username = GUSER;  
    $mail->Password = GPWD;           
    $mail->SetFrom($from, $from_name);
    $mail->Subject = $subject;
    $mail->Body = $body;
    $mail->AddAddress($to);
    if(!$mail->Send()) {
        $error = 'Mail error: '.$mail->ErrorInfo; 
        return false;
    } else {
        $error = 'Message sent!';
        return true;
    }
}

Answer 3

通过将这些行添加到标准PHPMailer配置中解决了几乎相同的问题。奇迹般有效。

$mail->SMTPKeepAlive = true;   
$mail->Mailer = “smtp”; // don't change the quotes!

在研究解决方案时，遇到了这段代码（来自Simon Chen），https://webolio.wordpress.com/2008/03/02/phpmailer-and-smtp-on-1and1-shared-hosting/#comment-89

Answer 4

Troubleshooting

您已添加此代码：

 $mail->SMTPOptions = array(
        'ssl' => array(
            'verify_peer' => false,
            'verify_peer_name' => false,
            'allow_self_signed' => true
        )
    );

并且启用Allow less secure apps：“通常会解决PHPMailer的问题，并且它并没有真正使您的应用程序显着降低安全性。据报道，更改此设置可能需要一个小时或更长时间才能生效，因此不要指望立即修复”

这项工作对我来说！

Answer 5

如果有人仍然无法解决问题，请检查以下主题并按照callmebob的回答。

PHPMailer - SMTP ERROR: Password command failed when send mail from my server

Answer 6

您缺少指示连接使用SSL的指令

require ("class.phpmailer.php");
$mail = new PHPMailer();
$mail->IsSMTP(); 
$mail->SMTPAuth = true;     // turn of SMTP authentication
$mail->Username = "YAHOO ACCOUNT";  // SMTP username
$mail->Password = "YAHOO ACCOUNT PASSWORD"; // SMTP password
$mail->SMTPSecure = "ssl";
$mail->Host = "YAHOO HOST"; // SMTP host
$mail->Port = 465;

然后添加其他部分

$webmaster_email = "[email protected]";       //Reply to this email ID
$email="[email protected]";                // Recipients email ID
$name="My Name";                              // Recipient's name
$mail->From = $webmaster_email;
$mail->FromName = "My Name";
$mail->AddAddress($email,$name);
$mail->AddReplyTo($webmaster_email,"My Name");
$mail->WordWrap = 50;                         // set word wrap
$mail->IsHTML(true);                          // send as HTML
$mail->Subject = "subject";
$mail->Body = "Hi,
This is the HTML BODY ";                      //HTML Body 
$mail->AltBody = "This is the body when user views in plain text format"; //Text Body 

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

作为旁注，我在使用Body + AltBody时遇到了麻烦，尽管它们应该起作用。结果，我编写了以下包装函数，它完美地运行。

<?php
require ("class.phpmailer.php");

// Setup Configuration for Mail Server Settings
$email['host']          = 'smtp.email.com';
$email['port']          = 366;
$email['user']          = '[email protected]';
$email['pass']          = 'from password';
$email['from']          = 'From Name';
$email['reply']         = '[email protected]';
$email['replyname']     = 'Reply To Name';

$addresses_to_mail_to = '[email protected];[email protected]';
$email_subject = 'My Subject';
$email_body = '<html>Code Here</html>';
$who_is_receiving_name = 'John Smith';

$result = sendmail(
    $email_body,
    $email_subject,
    $addresses_to_mail_to,
    $who_is_receiving_name
);

var_export($result);


function sendmail($body, $subject, $to, $name, $attach = "") {

  global $email;
  $return = false;

  $mail = new PHPMailer(true); // the true param means it will throw exceptions on errors, which we need to catch
  $mail->IsSMTP(); // telling the class to use SMTP
  try {
    $mail->Host       = $email['host']; // SMTP server
//    $mail->SMTPDebug  = 2;                     // enables SMTP debug information (for testing)
    $mail->SMTPAuth   = true;                  // enable SMTP authentication
    $mail->Host       = $email['host']; // sets the SMTP server
    $mail->Port       = $email['port'];                    // set the SMTP port for the GMAIL server
    $mail->SMTPSecure = "tls";
    $mail->Username   = $email['user']; // SMTP account username
    $mail->Password   = $email['pass'];        // SMTP account password
    $mail->AddReplyTo($email['reply'], $email['replyname']);
    if(stristr($to,';')) {
      $totmp = explode(';',$to);
      foreach($totmp as $destto) {
        if(trim($destto) != "") {
          $mail->AddAddress(trim($destto), $name);
        }
      }
    } else {
      $mail->AddAddress($to, $name);
    }
    $mail->SetFrom($email['user'], $email['from']);
    $mail->Subject = $subject;
    $mail->AltBody = 'To view the message, please use an HTML compatible email viewer!'; // optional - MsgHTML will create an alternate automatically
    $mail->MsgHTML($body);
    if(is_array($attach)) {
        foreach($attach as $attach_f) {
            if($attach_f != "") {
              $mail->AddAttachment($attach_f);      // attachment
            }
        }
    } else {
        if($attach != "") {
          $mail->AddAttachment($attach);      // attachment
        }
    }
    $mail->Send();
  } catch (phpmailerException $e) {
    $return = $e->errorMessage();
  } catch (Exception $e) {
    $return = $e->errorMessage();
  }

  return $return;
}

如果一切都失败，那么对于Gmail，您必须打开第三方应用程序的访问权限才能连接到您的Gmail帐户。

https://www.google.com/settings/security/lesssecureapps //打开它

如果您正在使用VPS和httpd服务，请检查您的httpd_can_sendmail是否已启用。

getsebool -a | grep mail

坚持下去

setsebool -P httpd_can_sendmail on

Answer 9

我修好了它 ...

https://github.com/PHPMailer/PHPMailer/tree/5.2-stable

<?php
require 'PHPMailerAutoload.php';

$mail = new PHPMailer;

//$mail->SMTPDebug = 3;                               // Enable verbose debug output

$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp.gmail.com';  // Specify main and backup SMTP servers
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = '[email protected]';                 // SMTP username
$mail->Password = 'pass';                           // SMTP password
//$mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 25;                                    // TCP port to connect to

$mail->setFrom('[email protected]', 'Mailer');
$mail->addAddress('[email protected]', 'User');     // Add a recipient

$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';
}

打开访问，享受..！这是Gmail帐户设置。
