PHP連接（）PHPMailer中的失敗錯誤

Question

我對PHP完全陌生，我想用PHP發送郵件。我有一個聯繫我們的表格，它會接受與我聯繫的人的電子郵件，因此郵件將發送給我。我正在使用來自https://github.com/PHPMailer/PHPMailer/tree/master的PHPMailer庫，以下是我正在使用的代碼片段。

<?php 
require("class.phpmailer.php"); 
$mail = new PHPMailer(); 
$mail->IsSMTP(); 

$mail->SMTPSecure = 'tls'; 

$mail->Host  = "resolver1.opendns.com"; // this SMTP server of my machine 
//$mail->Host  = "208.67.222.222";//ip ; which one to use the resolver1.opendns.com or 208.67.222.222 ??? 

$mail->From  = "xyz@gamil.com;//email id of the person 

$mail->AddAddress("datta.dhonde@coreathena.com");//my email id 

$mail->Subject = "First PHPMailer Message"; 
$mail->Body  = "Hi! \n\n This is my first e-mail sent through PHPMailer."; 
$mail->WordWrap = 50; 

if(!$mail->Send()) 
{ 
    echo 'Message was not sent.'; 
    echo 'Mailer error: ' . $mail->ErrorInfo; 
} 
else 
{ 
    echo 'Message has been sent.'; 
} 
?> 

我收到錯誤「消息未發送.Mailer錯誤：SMTP連接（）失敗。」 我沒有得到什麼問題..？ $ mail-> Host =「」;請評論這代表什麼？

Answer 1

你應該檢查resolver1.opendns.com的tcp端口25，它表明是阻止或不啓動stmpd，如sendmail或某些MTA。

嘗試 的telnet resolver1.opendns.com 25

，你會發現TCP端口25未打開。

Answer 2

添加$mail->SMTPDebug = 1;並嘗試調試該問題。

Answer 3

也許這是你的配置問題。 PHPMailer的配置

例子是這樣的：

<?php 
require 'class.phpmailer.php'; 

$mail = new PHPMailer; 

$mail->isSMTP();          // Set mailer to use SMTP 
$mail->Host = 'smtp1.example.com;smtp2.example.com'; // Specify main and backup server 
$mail->SMTPAuth = true;        // Enable SMTP authentication 
$mail->Username = 'jswan';       // SMTP username 
$mail->Password = 'secret';       // SMTP password 
$mail->SMTPSecure = 'tls';       // Enable encryption, 'ssl' also accepted 

$mail->From = 'from@example.com'; 
$mail->FromName = 'Mailer'; 
$mail->addAddress('josh@example.net', 'Josh Adams'); // Add a recipient 
$mail->addAddress('ellen@example.com');    // Name is optional 
$mail->addReplyTo('info@example.com', 'Information'); 
$mail->addCC('cc@example.com'); 
$mail->addBCC('bcc@example.com'); 

$mail->WordWrap = 50;         // Set word wrap to 50 characters 
$mail->addAttachment('/var/tmp/file.tar.gz');   // Add attachments 
$mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name 
$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; 
    exit; 
} 

echo 'Message has been sent'; 

這裏$ MAIL->主機是SMTP郵件服務器。通常以smtp開始。

作爲@joydesigner的例子，要通過SMTP連接，您需要通過hostname, username and password，然後它應該連接併發送電子郵件。

$mail->Host = 'smtp1.example.com;smtp2.example.com'; // Specify main and backup server 
$mail->SMTPAuth = true;        // Enable SMTP authentication 
$mail->Username = 'jswan';       // SMTP username 
$mail->Password = 'secret';       // SMTP password 
$mail->SMTPSecure = 'tls';       // tls or ssl connection as req 

在這裏我看到你已經通過只，host信息，請添加username & password以及和嘗試一次。

還要檢查TLS/SSL PORT爲您開放，您的服務器：

檢查有：

telnet resolver1.opendns.com 25
