EOF caught while checking if connected phpmailer - php

Question

require 'PHPMailerAutoload.php';
$mail = new PHPMailer;
$mail->SMTPDebug = 3; // Enable verbose debug output
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = 'myhost'; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = 'myusername'; // SMTP username
$mail->Password = 'mypassword'; // SMTP password
$mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 1060; // TCP port to connect to
$mail->setFrom('test#gmail.com', 'test');
$mail->isHTML(true); // Set email format to HTML
$mail->addAddress('test#gmail.com'); // Add a recipient
for($i=0;$i<1;$i++){
$mail->Subject = "test bulk email ".$i;
$mail->Body = "this is email ".$i;
if(!$mail->Send())
{
$error_message = "Mailer Error: " . $mail->ErrorInfo;
}
}
echo $error_message;
When I run this code, I get this error:
Connection: opened 2018-03-05 09:24:25 SERVER -> CLIENT: 2018-03-05 09:24:25 SMTP NOTICE: EOF caught while checking if connected 2018-03-05 09:24:25 Connection: closed 2018-03-05 09:24:25 SMTP Error: Could not connect to SMTP host.
How do I fix this?

Answer 1

You're using an unusual port number for SMTP submission, so check you have the right one for your host. It would usually be 587 when using SMTPSecure = 'tls'.
You're setting a gmail from address while sending through another host; that will cause you to fail SPF checks and your messages will either be blocked or spam filtered.
If you want to send to a list, follow the mailing list example provided with PHPMailer - your code contains some mistakes that will probably result in duplicate messages.
