SMTP ERROR: Failed to connect to server: Connection refused (111) with Office365
Sorry if this is a road heavily traveled. I've seen the other posts about this but nothing in them has either solved the problem I'm having or ignited a lightbulb that helped me solve it myself.
Here's my code:
require 'PHPMailerAutoload.php';
$config = parse_ini_file('/path/to/file/config.ini', true);
$mail = new PHPMailer;
$mail->SMTPDebug = 3;
$mail->Debugoutput = 'html';
$mail->isSMTP();
$mail->Host = $config['host']; //smtp.office365.com
$mail->SMTPAuth = true;
$mail->Username = $config['username']; //[email protected]
$mail->Password = $config['password']; //confirmed this is being passed correctly
$mail->SMTPSecure = 'tls';
$mail->Port = 587;
$mail->From = $config['username'];
$mail->FromName = 'Website Forms';
$mail->addAddress('[email protected]', 'Some Name');
$mail->addReplyTo('[email protected]', 'SenderFirst SenderLast');
$mail->addBCC('[email protected]');
$mail->isHTML(true);
$mail->Subject = 'Contact Form Submission';
$mail->Body = 'Some html here';
$mail->AltBody = 'Some alt content here';
if(!$mail->send()) {
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
//perform success actions
exit();
}
I've confirmed that the domain, username and password are all correct and being passed in correctly. Important to note that this worked on our local dev server prior to launch. Once the site was moved to our hosting account (Hostgator) is when it stopped working. I've confirmed with HG that port 587 is open on our server.
Here is the error message I'm seeing:
Connection: opening to smtp.office365.com:587, t=10, opt=array ()
SMTP ERROR: Failed to connect to server: Connection refused (111)
SMTP connect() failed.
Message could not be sent.Mailer Error: SMTP connect() failed.
Any help that can be provided is very much appreciated, even if it's just a link to an article that explains why it won't work now that it's in our production environment.
Answer
None of the answers worked for me. After many hours, I found the problem, but only works for Cpanel/WHM
- Login into WHM.
- Go to ConfigServer Security & Firewall inside plugins option.
- Click on Firewall configuration
- Filter by SMTP Settings
- Look for SMTP_ALLOWUSER option and add the Cpanel account's username separated by coma
- Restart the firewall.
If you don't have access to WHM ask your provider.
