SMTP connect() failed error in PHPMailer
提问by Datta Dhonde
I am completely new to PHP and I want to send a mail using PHP. I have a Contact Us form whcih will accept email is of the person contacting me and therefore the mail will be sent to me. I am using PHPMailer library from https://github.com/PHPMailer/PHPMailer/tree/masterand following is the code snippet I am using.
我对 PHP 完全陌生，我想使用 PHP 发送邮件。我有一个联系我们表格，它会接受与我联系的人的电子邮件，因此邮件将发送给我。我正在使用https://github.com/PHPMailer/PHPMailer/tree/master 中的PHPMailer 库，以下是我正在使用的代码片段。
<?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 = "[email protected];//email id of the person
$mail->AddAddress("[email protected]");//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.';
}
?>
I am getting the error " Message was not sent.Mailer error: SMTP connect() failed." I am not getting what is the problem..? $mail->Host = ""; please comment on what this stands for??
我收到错误消息“邮件未发送。邮件程序错误：SMTP 连接（）失败。” 我不明白是什么问题..？$mail->Host = ""; 请评论这代表什么？

As very well exampled by @joydesigner, To connect via SMTP, you will need to pass hostname, username and passwordand then it should connect and send email.
正如@joydesigner 所举的例子，要通过 SMTP 连接，您需要通过hostname, username and password，然后它应该连接并发送电子邮件。
$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
Here I see you have passed only, hostinformation, pls add username & passwordas well and try once.
在这里我看到您只通过了，host信息，请添加username & password并尝试一次。
Also check that TLS/SSL PORTis open for your server:
还要检查TLS/SSL PORT您的服务器是否已打开：
check with:
检查：
telnet resolver1.opendns.com 25

Maybe it is your configuration problem.
可能是你的配置问题。
example of phpmailer configuration is like this:
phpmailer 配置示例如下：
<?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 = '[email protected]';
$mail->FromName = 'Mailer';
$mail->addAddress('[email protected]', 'Josh Adams'); // Add a recipient
$mail->addAddress('[email protected]'); // Name is optional
$mail->addReplyTo('[email protected]', 'Information');
$mail->addCC('[email protected]');
$mail->addBCC('[email protected]');
$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';
Here the $mail->Host is the smtp mail server. Normally started with smtp.
这里的 $mail->Host 是 smtp 邮件服务器。通常以 smtp 开始。

You should check the tcp port 25 of the resolver1.opendns.com , it seens being block or not starting up the stmpd such as sendmail or some MTA.
您应该检查 resolver1.opendns.com 的 tcp 端口 25，它看到被阻止或未启动 stmpd，例如 sendmail 或某些 MTA。
try telnet resolver1.opendns.com 25
试试 telnet resolver1.opendns.com 25
and you will find tcp port 25 is not opened.
你会发现tcp 25端口没有打开。
