I want to send an email without SSL using PHPMailer. I have enabled the debug mode so that I can check the details in the logs.
$mail = new PHPMailerPHPMailerPHPMailer(); $mail->IsSMTP(true); // enable SMTP $mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only $mail->SMTPAuth = true; // authentication enabled $mail->SMTPSecure = false; // secure transfer enabled REQUIRED for Gmail $mail->Host = "mail.company.co.uk"; $mail->Port = 25; // or 587 $mail->IsHTML(true); $mail->Username = "email@company.co.uk"; $mail->Password = "password_of_username"; $mail->SetFrom($email,$name); $mail->Subject = $subject; $mail->Body = $message; $mail->AddAddress($to);
This is giving an exception:
2018-09-28 10:04:27 CLIENT -> SERVER: EHLO localhost<br> 2018-09-28 10:04:27 CLIENT -> SERVER: STARTTLS<br> SMTP Error: Could not connect to SMTP host.<br> 2018-09-28 10:04:28 CLIENT -> SERVER: QUIT<br> 2018-09-28 10:04:28 <br> SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting<br> Mailer Error: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

Answer
You’ve based your code on an old example, which doesn’t help. You can’t see what’s going on because you’ve only used 1
for SMTPDebug
; set it to 2
.
Your mail server is advertising that it supports STARTTLS on port 25, so PHPMailer is using it automatically. You can disable encryption entirely by doing this:
$mail->SMTPAutoTLS = false; $mail->SMTPSecure = false;
However, I’d recommend not doing this; fix your TLS config instead. You probably need to update your local CA certificate bundle – see the troubleshooting guide for more details.
