使用PHPMailer的PHP中的SMTP身份验证问题，Pear Mail的工作原理

php email smtp phpmailer pear
2022-08-30 21:27:45

我在使用PHPMailer类发送电子邮件时遇到问题，但它可以与PEAR Mail：：factory一起使用。

我想问题出在SMTP身份验证上，但我找不到问题。

有问题的代码是：

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

$mail = new PHPMailer();

$mail->IsSMTP();       // set mailer to use SMTP
$mail->Host = 'mail.xxx.com.br';  // my host here
$mail->SMTPAuth = true;     // turn on SMTP authentication
$mail->Username = 'xxx@xxx.com.br';  // a valid email here
$mail->Password = '***';  // the password from email
$mail->From = 'from@xxx.com.br';
$mail->SMTPDebug = true;
$mail->AddReplyTo('from@xxx.com.br', 'Test');

$mail->FromName = 'Test SMTP';
$mail->AddAddress('teste@xxx.com.br', 'teste@xxx.com.br');

$mail->Subject = 'Test SMTP';
$mail->IsHTML(true);
$mail->Body = '<b>Teste</b><br><h1>teste 2</h1>';   
//$mail->Send();

if(!$mail->Send())
{
   echo "Message could not be sent. <p>";
   echo "Mailer Error: " . $mail->ErrorInfo;
   exit;
}

?>

使用 PEAR 的代码是：

<?php
include('Mail.php');
include('Mail/mime.php');

$text = 'Versao em texto';
$html = '<html><body>Versao de email em <b>HTML</b></body></html>';
$crlf = "\n";
$hdrs = array(
              'From'    => 'from@xxx.com.br',
              'Subject' => 'Test  - mail.php'
              );

$mime = new Mail_mime($crlf);

$mime->setTXTBody($text);
$mime->setHTMLBody($html);

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

$mail = Mail::factory('smtp',
  array ('host' => 'mail.xxx.com.br',
    'debug'=> true,
    'auth' => true,
    'username' => 'xxx@xxx.com.br',
    'password' => '***'));

$mail->send('teste@xxx.com.br', $hdrs, $body);
?>

当我运行代码时，调试激活（SMTPDebug = True）的问题，我得到：

答案 1

奇怪的问题，我通过评论这行解决了

//$mail->IsSmtp();

最后一个 phpmailer 版本 （5.2）


答案 2

尝试添加以下内容：

$mail->SMTPAuth   = true;
$mail->SMTPSecure = "tls";

通过查看调试日志，您可以注意到失败的PhpMailer日志显示以下内容：

(..snip..)
SMTP -> ERROR: AUTH not accepted from server: 250 orion.bommtempo.net.br Hello admin-teste.bommtempo.com.br [200.155.129.6]
(..snip..)
503 AUTH command used when not advertised
(..snip..)

虽然您成功的 PEAR 日志显示以下内容：

DEBUG: Send: STARTTLS
DEBUG: Recv: 220 TLS go ahead

我的猜测是，明确要求PHPMailer使用TLS将使其走上正确的轨道。
另外，请确保您使用的是PHPMailer的最新版本。
