无法使用 PHPMailer 远程连接到我的电子邮件服务器

Cannot connect remotely to my email server using PHPMailer

我正在编写一个 PHP 脚本,使用 PHPMailer 自动发送电子邮件。 出于测试目的,我使用了一个带有应用程序密码的 Gmail 帐户,一切正常。 当我用我的专业电子邮件替换 Gmail 帐户配置时,PHP 连接脚本会持续加载一段时间并以此消息结束。 SMTPDebug 设置为 3。

2015-11-16 22:43:30 SERVER -> CLIENT: +OK Dovecot ready. 2015-11-16 22:43:30 CLIENT -> SERVER: EHLO localhost

这是什么意思?

这是我用来测试与电子邮件服务器的连接的 PHP 函数

<?php

require('../PHPMailer-master/PHPMailerAutoload.php'); 

function smtpMailer() {
    $mail = new PHPMailer();  
    $mail->IsSMTP(); // active SMTP
    $mail->SMTPDebug = 2;  
    $mail->Host = 'mail.mycompany.com';
    $mail->Port = 587;
    //$mail->Username = "myaccount@mycompany.com";
    //$mail->Password = "mypassword";
    $mail->SetFrom = "myaccount@mycompany.com";
    $mail->FromName = 'foxy';
    $mail->addAddress('sendTo@gmail.com', 'John Doe');  
    $mail->WordWrap = 50;                                

     $mail->Subject = 'Here is the subject';
     $mail->Body = 'This is the body in plain text ';


if(!$mail->Send()) {
  echo "Mailer Error: " . $mail->ErrorInfo;
} else {
  echo "Message sent!";
}


}

smtpMailer();

?>

错误

2015-11-17 01:44:14 SERVER -> CLIENT: 220 mycompany.com ESMTP Ready 2015-11-17 01:44:14

谢谢。

这是我正在使用的代码

$mail = new PHPMailer();
$mail->CharSet = "UTF-8";
$mail->Username = "no-reply@mycompany.com";
$mail->Password = "password";
$mail->AddAddress($email);
$mail->FromName = "Any Text";
$mail->Subject = $sub;
$mail->IsHTML(true);
$mail->Body = $code;
$mail->Host = "192.168.20.47"; // Is IP example that I show here 
$mail->Port = 25;
$mail->IsSMTP();
$mail->SMTPAuth = true;
$mail->From = $mail->Username;
if ($mail->Send()) {
    echo "Message send!";
}
else {
    echo "Mailer Error: " . $mail->ErrorInfo;
}

希望对您有所帮助。
