无法连接到SMTP主机。讯息无法发送 [英] Could not connect to SMTP host. Message could not be sent

问题描述

SMTP错误：无法连接到SMTP主机。讯息无法发送。
Mailer错误：SMTP错误：无法连接到SMTP主机。

我在Stack overflow上发现了另一个答案的许多提示但不行。我试过港口号465/587/65。甚至下面的代码适用于我的本地系统如果我设置端口587.但在服务器，它不工作。

  require（'class.phpmailer.php'）; 
 require（'class.smtp.php'）; 
 
 $ mail = new PHPMailer（）; 
 
 $ mail-> IsSMTP（）; 
 $ mail-> SMTPSecure =ssl; 
 $ mail-> SMTPAuth = true; 
 $ mail-> Host =smtp.gmail.com; 
 $ mail-> Username =FromEmailId; 
 $ mail-> Password =密码; 
 $ mail-> Port = 465; 
 $ mail-> From =FromEmailId; 
 $ mail-> AddAddress（ToEmail）; 
 $ mail-> IsHTML（true）; 
 $ mail->主题=这是主题; 
 $ mail-> Body =这是黑体中的HTML消息正文< b>< / b>; 
 
 if（！$ mail-> Send（））
 {
 echo无法发送消息< p>; 
 echoMailer Error：。 $ MAIL-> ERRORINFO; 
退出; 
} 
 echo已发送消息; 
  

解决方案

首先注销您的Gmail帐户

然后打开此网址

点击继续按钮

下一步
更改端口和SMTPsecure

  $ mail-> SMTPSecure =tls; 
 $ mail-> Port = 587; 
  

When I sent email from server then it gives me two error -

SMTP Error: Could not connect to SMTP host. Message could not be sent. Mailer Error: SMTP Error: Could not connect to SMTP host.

I found many hints on another answers on Stack overflow but doesn't work. I tried port no 465/587/65. Even below code works proper on my local system If i set port 587. But in server, It doesn't work.

require('class.phpmailer.php');
require('class.smtp.php');

$mail = new PHPMailer();

$mail->IsSMTP();      
$mail->SMTPSecure = "ssl";
$mail->SMTPAuth = true;
$mail->Host = "smtp.gmail.com"; 
$mail->Username = "FromEmailId";
$mail->Password = "Password"; 
$mail->Port = 465;
$mail->From = "FromEmailId";
$mail->AddAddress("ToEmail");      
$mail->IsHTML(true);                                  
$mail->Subject = "Here is the subject";
$mail->Body    = "This is the HTML message body <b>in bold!</b>";

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

解决方案

First logout the your gmail account

then open this url use this yrl

click the continue button

Next change the port and SMTPsecure

$mail->SMTPSecure = "tls";
$mail->Port = 587;
