使用GMail SMTP服务器从PHP页面发送电子邮件

我正在尝试从PHP页面通过GMail的SMTP服务器发送电子邮件，但出现此错误：

身份验证失败[SMTP：SMTP服务器不支持身份验证（代码：250，响应：mx.google.com，为您提供服务，[98.117.99.235]大小为35651584 8位MIME STARTTLS ENHANCEDSTATUSCODES PIPELINING）]

有人可以帮忙吗？这是我的代码：

<?php
require_once "Mail.php";

$from = "Sandra Sender <sender@example.com>";
$to = "Ramona Recipient <ramona@microsoft.com>";
$subject = "Hi!";
$body = "Hi,\n\nHow are you?";

$host = "smtp.gmail.com";
$port = "587";
$username = "testtest@gmail.com";
$password = "testtest";

$headers = array ('From' => $from,
  'To' => $to,
  'Subject' => $subject);
$smtp = Mail::factory('smtp',
  array ('host' => $host,
    'port' => $port,
    'auth' => true,
    'username' => $username,
    'password' => $password));

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) {
  echo("<p>" . $mail->getMessage() . "</p>");
 } else {
  echo("<p>Message successfully sent!</p>");
 }
?>

// Pear Mail Library
require_once "Mail.php";

$from = '<fromaddress@gmail.com>';
$to = '<toaddress@yahoo.com>';
$subject = 'Hi!';
$body = "Hi,\n\nHow are you?";

$headers = array(
    'From' => $from,
    'To' => $to,
    'Subject' => $subject
);

$smtp = Mail::factory('smtp', array(
        'host' => 'ssl://smtp.gmail.com',
        'port' => '465',
        'auth' => true,
        'username' => 'johndoe@gmail.com',
        'password' => 'passwordxxx'
    ));

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) {
    echo('<p>' . $mail->getMessage() . '</p>');
} else {
    echo('<p>Message successfully sent!</p>');
}

使用Swift mailer，通过Gmail凭据发送邮件非常容易：

<?php
require_once 'swift/lib/swift_required.php';

$transport = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, "ssl")
  ->setUsername('GMAIL_USERNAME')
  ->setPassword('GMAIL_PASSWORD');

$mailer = Swift_Mailer::newInstance($transport);

$message = Swift_Message::newInstance('Test Subject')
  ->setFrom(array('abc@example.com' => 'ABC'))
  ->setTo(array('xyz@test.com'))
  ->setBody('This is a test mail.');

$result = $mailer->send($message);
?>

您的代码似乎未使用TLS（SSL），这是将邮件传递到Google所必需的（并使用端口465或587）。

您可以通过设置

$host = "ssl://smtp.gmail.com";

您的代码看起来像这样的示例，该示例在主机名方案中引用了ssl：//。

我不建议使用Pear Mail。自2010年以来未进行过更新。源代码几乎已经过时，以PHP 4风格编写，并且已经发布了许多错误/错误（谷歌它）。我正在使用Swift Mailer。

Swift Mailer集成到任何用PHP 5编写的Web应用程序中，从而提供了一种灵活而优雅的面向对象的方法来发送具有多种功能的电子邮件。

使用SMTP，sendmail，postfix或您自己的自定义传输实现发送电子邮件。

支持需要用户名和密码和/或加密的服务器。

在不剥离请求数据内容的情况下，免受报头注入攻击。

发送符合MIME的HTML /多部分电子邮件。

使用事件驱动的插件自定义库。

处理大型附件和内嵌/嵌入图像时占用的内存较少。

它是一个免费的开放源代码，您可以下载Swift Mailer并上传到您的服务器。（功能列表是从所有者网站复制的）。

Gmail SSL / SMTP和Swift Mailer的工作示例在这里...

// Swift Mailer Library
require_once '../path/to/lib/swift_required.php';

// Mail Transport
$transport = Swift_SmtpTransport::newInstance('ssl://smtp.gmail.com', 465)
    ->setUsername('username@gmail.com') // Your Gmail Username
    ->setPassword('my_secure_gmail_password'); // Your Gmail Password

// Mailer
$mailer = Swift_Mailer::newInstance($transport);

// Create a message
$message = Swift_Message::newInstance('Wonderful Subject Here')
    ->setFrom(array('sender@example.com' => 'Sender Name')) // can be $_POST['email'] etc...
    ->setTo(array('receiver@example.com' => 'Receiver Name')) // your email / multiple supported.
    ->setBody('Here is the <strong>message</strong> itself. It can be text or <h1>HTML</h1>.', 'text/html');

// Send the message
if ($mailer->send($message)) {
    echo 'Mail sent successfully.';
} else {
    echo 'I am sure, your configuration are not correct. :(';
}

我希望这有帮助。快乐的编码... :)

<?php
date_default_timezone_set('America/Toronto');

require_once('class.phpmailer.php');
//include("class.smtp.php"); // optional, gets called from within class.phpmailer.php if not already loaded

$mail             = new PHPMailer();

$body             = "gdssdh";
//$body             = eregi_replace("[\]",'',$body);

$mail->IsSMTP(); // telling the class to use SMTP
//$mail->Host       = "ssl://smtp.gmail.com"; // SMTP server
$mail->SMTPDebug  = 1;                     // enables SMTP debug information (for testing)
                                           // 1 = errors and messages
                                           // 2 = messages only
$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->SMTPSecure = "ssl";                 // sets the prefix to the servier
$mail->Host       = "smtp.gmail.com";      // sets GMAIL as the SMTP server
$mail->Port       = 465;                   // set the SMTP port for the GMAIL server
$mail->Username   = "user@gmail.com";  // GMAIL username
$mail->Password   = "password";            // GMAIL password

$mail->SetFrom('contact@prsps.in', 'PRSPS');

//$mail->AddReplyTo("user2@gmail.com', 'First Last");

$mail->Subject    = "PRSPS password";

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

$mail->MsgHTML($body);

$address = "user2@yahoo.co.in";
$mail->AddAddress($address, "user2");

//$mail->AddAttachment("images/phpmailer.gif");      // attachment
//$mail->AddAttachment("images/phpmailer_mini.gif"); // attachment

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

?>

SwiftMailer可以使用外部服务器发送电子邮件。

这是显示如何使用Gmail服务器的示例：

require_once "lib/Swift.php";
require_once "lib/Swift/Connection/SMTP.php";

//Connect to localhost on port 25
$swift =& new Swift(new Swift_Connection_SMTP("localhost"));


//Connect to an IP address on a non-standard port
$swift =& new Swift(new Swift_Connection_SMTP("217.147.94.117", 419));


//Connect to Gmail (PHP5)
$swift = new Swift(new Swift_Connection_SMTP(
    "smtp.gmail.com", Swift_Connection_SMTP::PORT_SECURE, Swift_Connection_SMTP::ENC_TLS));

问题中列出的代码需要进行两项更改

$host = "ssl://smtp.gmail.com";
$port = "465";

SSL连接需要端口465。

通过Gmail使用phpMailer库发送邮件，请从Github下载库文件

<?php
/**
 * This example shows settings to use when sending via Google's Gmail servers.
 */
//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't have access to that
date_default_timezone_set('Etc/UTC');
require '../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)
// 1 = client messages
// 2 = client and server messages
$mail->SMTPDebug = 2;
//Ask for HTML-friendly debug output
$mail->Debugoutput = 'html';
//Set the hostname of the mail server
$mail->Host = 'smtp.gmail.com';
// use
// $mail->Host = gethostbyname('smtp.gmail.com');
// if your network does not support SMTP over IPv6
//Set the SMTP port number - 587 for authenticated TLS, a.k.a. RFC4409 SMTP submission
$mail->Port = 587;
//Set the encryption system to use - ssl (deprecated) or tls
$mail->SMTPSecure = 'tls';
//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";
//Password to use for SMTP authentication
$mail->Password = "yourpassword";
//Set who the message is to be sent from
$mail->setFrom('from@example.com', 'First Last');
//Set an alternative reply-to address
$mail->addReplyTo('replyto@example.com', 'First Last');
//Set who the message is to be sent to
$mail->addAddress('whoto@example.com', 'John Doe');
//Set the subject line
$mail->Subject = 'PHPMailer GMail SMTP test';
//Read an HTML message body from an external file, convert referenced images to embedded,
//convert HTML into a basic plain-text alternative body
$mail->msgHTML(file_get_contents('contents.html'), dirname(__FILE__));
//Replace the plain text body with one created manually
$mail->AltBody = 'This is a plain-text message body';
//Attach an image file
$mail->addAttachment('images/phpmailer_mini.png');
//send the message, check for errors
if (!$mail->send()) {
    echo "Mailer Error: " . $mail->ErrorInfo;
} else {
    echo "Message sent!";
}

我也有这个问题。我设置了正确的设置，并启用了安全性较低的应用程序，但仍然无法正常工作。最后，我启用了此https://accounts.google.com/UnlockCaptcha，它对我有用。我希望这可以帮助别人。

Gmail需要465端口，也是phpmailer的代码：)

要在Ubuntu中安装PEAR的Mail.php，请运行以下命令：

    sudo apt-get install php-pear
    sudo pear install mail
    sudo pear install Net_SMTP
    sudo pear install Auth_SASL
    sudo pear install mail_mime

我有一个GSuite帐户没有“ @ gmail.com” sufix的解决方案。我也认为它适用于@ gmail.com的GSuite帐户，但还没有尝试过。首先，您应该有权为您的GSuite帐户更改选项“allos¿w安全性较低的应用程序”。如果您具有特权（可以登录帐户设置->安全性），则必须停用“两步验证”，然后转到页面末尾并设置为“是”，以允许安全性较低的应用程序。就这样。如果您没有更改这些选项的特权，则该线程的解决方案将不起作用。检查https://support.google.com/a/answer/6260879?hl=zh_CN更改为“允许更少...”选项。

我尝试了@shasi kanth提供的建议，但没有成功。我阅读了文档，几乎没有进行任何更改。因此，我设法使用此代码通过Gmail发送邮件，其中composer通过composer获得了vendor / autoload.php，要求“ swiftmailer / swiftmailer：^ 6.0”：

<?php
     require_once 'vendor/autoload.php';
     $transport = (new Swift_SmtpTransport('smtp.gmail.com', 465, 'ssl'))->setUsername ('SendingMail')->setPassword ('Password');

     $mailer = new Swift_Mailer($transport);

     $message = (new Swift_Message('test'))
      ->setFrom(['Sending mail'])
      ->setTo(['Recipient mail'])
      ->setBody('Message')
  ;

     $result = $mailer->send($message);
    ?>

组

'auth' => false,

另外，请查看端口25是否起作用。
