SMTP连接超时PHP电子邮件

将其标记为重复之前，请先阅读。我已经尝试了一切！

我一直在尝试使用我以前使用过的SwiftMailer和PHPMailer从我的网站表单发送电子邮件。由于某种原因，最近几天，我没有让他们工作。每次，无论设置如何，我都会收到错误110-与smtp服务器的连接超时。我尝试从我的gmail帐户和1and1.com电子邮件帐户使用身份验证。我什至加了一张支票fsockopen以及gmail，godaddy或1and1的smtp服务器都可以连接。而且我什至打过两次电话1and1，询问有关防火墙以及任何会阻止我的电子邮件的问题，他们说他们不知道可能是什么问题。我已经尝试了多个Stackoverflow问题上列出的所有内容，但无法解决此问题。有什么事情可以防止这种情况发生吗？我的互联网连接（尝试在家办公）我很迷路！我的PHPMailer和SwiftMailer代码将粘贴在下面。请记住，我已经尝试使用端口465 / ssl和端口587 / tls，但都没有起作用。

require 'PHPMailerAutoload.php';

$mail = new PHPMailer();
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->Port = 465;
$mail->SMTPAuth = true;
$mail->Username = '[email protected]';
$mail->Password = 'password';
$mail->SMTPSecure = 'ssl';
$mail->From = '[email protected]';
$mail->addAddress('[email protected]');
$mail->isHTML(true);

$checkconn = fsockopen($mail->Host, $mail->Port, $errno, $errstr, 5);

if($_GET['formName'] == 'join')
{
    $text = 'Name: <b>' . $_POST['first_name_join']. " " .$_POST['last_name_join']. "</b>".
             "<br>Phone: <b>".$_POST['phone_join']. "</b>".
             "<br>Email: <b>".$_POST['email_join']. "</b>".
             "<br>Date of Birth: <b>".$_POST['birth_month']. "/" .$_POST['birth_day']. "/" .$_POST['birth_day']. "</b>".
             "<br>Message: <br><b>".$_POST['message_join']. "</b>";
}
else
{
    $text = 'Name: <b>' . $_POST['full_name_sponsor']. "</b>".
             "<br>Company/Organization: <b>" . $_POST['company_sponsor']. "</b>".
             "<br>Phone: <b>".$_POST['phone_sponsor']. "</b>".
             "<br>Email: <b>".$_POST['email_sponsor']. "</b>".
             "<br>Message: <br><b>".$_POST['message_sponsor']. "</b>";
}



$mail->Subject = $_GET['formName'] == 'join' ? 'Join Inquiry' : 'Sponsorship Inquiry' ;
$mail->Body    = $text;

if (!$checkconn)
{
    echo "($errno) $errstr\n\n";
}
if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

require_once 'swiftmailer/swift_required.php';

}

// Create a message
$subject = $_GET['formName'] == 'join' ? 'Join Inquiry' : 'Sponsorship Inquiry' ;
$message = Swift_Message::newInstance($subject)
  ->setFrom(array('[email protected]'))
  ->setTo(array('[email protected]')) 
  ->setBody($text, 'text/html');

// Send the message
$result = $mailer->send($message);
