你如何使用谷歌的梨邮件mime.我发现这可以让你使用谷歌邮件,但不是邮件mime：http://globalconstant.scnay.com/2009/11/06/sending-email-through-gmail-using-php/

require_once "Mail.php";
require_once "Mail/mime.php";

$from = "Sender <*******@googlemail.com>";
$to = "Receiver <*******@googlemail.com>";
$subject = "Welcome to SITENAME!";
$crlf = "\n";
$html = "<h1> This is HTML </h1>";

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


$host = "smtp.gmail.com";
$port = 465;
$username = "********@googlemail.com";
$password = "********";

$mime = new Mail_mime($crlf);
$mime->setHTMLBody($html);

$body = $mime->get();
$headers = $mime->headers($headers);

$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 $mail->getMessage();
} else {
echo "Message sent successfully!";
}
echo "\n";

我一直在

Failed to add recipient: @localhost
[SMTP: Invalid response code received
from server (code: 555, response:
5.5.2 Syntax error. f52sm5542930wes.35)]

编辑：

现在收到了电子邮件,但结果如下：

This is a message I sent from <a href=3D"http://www.php.net/">PHP</a> using=
 the PEAR Mail package and SMTP through Gmail. Enjoy!

解决方法:

看起来您的电子邮件标题存在问题.我根据梨邮件文档更新了您的代码(http://pear.php.net/manual/en/package.mail.mail-mime.example.php)：

require_once "Mail.php";
require_once "Mail/mime.php";

$from = "Sender <*******@googlemail.com>";
$to = "Receiver <*******@googlemail.com>";
$subject = "Welcome to SITENAME!";
$crlf = "\n";
$html = "<h1> This is HTML </h1>";

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


//$host = "smtp.gmail.com";
$host = "ssl://smtp.gmail.com"; // try this one to use ssl
$port = 465;
$username = "********@googlemail.com";
$password = "********";

//$mime = new Mail_mime($crlf);
$mime =  new Mail_mime(array('eol' => $crlf)); //based on pear doc     
$mime->setHTMLBody($html);

//$body = $mime->get();
$body = $mime->getMessageBody(); //based on pear doc above
$headers = $mime->headers($headers);

$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 $mail->getMessage();
} else {
echo "Message sent successfully!";
}
echo "\n";

它对我有用,所以我希望它对你有用！
干杯,
