使用Swift邮件程序,通过Gmail凭据发送邮件非常简单:

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);
?>

您的代码似乎没有使用TLS(SSL),这是向Google发送邮件(以及使用端口465或587)所必需的.

您可以通过设置来完成此操作

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

您的代码看起来很可疑,就像这个在主机名方案中引用ssl://的示例一样.

我不推荐Pear Mail.它自2010年以来一直没有更新.还阅读源文件; 源代码几乎已过时,以PHP 4风格编写,并发布了许多错误/错误(谷歌).我正在使用Swift Mailer.

Swift Mailer集成到用PHP 5编写的任何Web应用程序中,提供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防止标头注入攻击.

发送符合MIME的HTML /多部分电子邮件.

使用事件驱动的插件来自定义库.

处理内存使用率低的大附件和内嵌/嵌入式图像.

它是一个免费的开源您可以下载Swift Mailer并上传到您的服务器.(功能列表从所有者网站复制).

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

// 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 message itself. It can be text or 
HTML
.', '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...... :)

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.

这是一个显示如何使用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处更改

$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

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。
