Using IIS 7 and PHP7.1 We i managed to connect my server to our SMTP server (on a different IP Address) I did this by quiet simply editing my php.ini file

SMTP = mail.<Domain>.co.uk
smtp_port = 25
sendmail_from = mail@<Domain>.co.uk

And by calling a php script, an email was sent

<?php
   $msg = "Hello Do I Work   Im From the Server";
   mail("joe@<Domain>.co.uk","My subject",$msg);
?>

This worked providing that the email recipient was on the same domain.

However the request came for emails to be sent to anyone. When i tried this, using above code and settings i got this error

PHP Warning:  mail(): SMTP server response: 550 5.7.1 Unable to relay in …

Having a quick read i found that PHP 7.1 don't allow smtp passwords which the lack caused the above error. Id need a external mail library 1) Was this correct

i downloaded and installed phpmailer (i can change this if required) and ran the following script

<?php
    require_once "PHPMailerAutoload.php";
    $mail = new PHPMailer;
    $mail->SMTPDebug = 3;                               
    $mail->isSMTP();            
    $mail->Host = "mail.<Domain>.co.uk";
    $mail->SMTPAuth = true;                          
    $mail->Username = "mail@<Domain>.co.uk";                 
    $mail->Password = "<Password>";                           
    $mail->SMTPSecure = "tls";                           
    $mail->Port = 25;
    $mail->From = "mail@<Domain>.co.uk";
    $mail->FromName = "Mail";
    $mail->addAddress("joe@<Domain>.co.uk"); 
    $mail->addReplyTo("mail@<Domain>.co.uk", "Reply");
    $mail->isHTML(true);
    $mail->Subject = "Test";
    $mail->Body = "From the Server";

    if(!$mail->send()) 
   {
        echo "Mailer Error: " . $mail->ErrorInfo;
    }
    else
      {
             echo "Message has been sent successfully";
    }
?>

I ran this and got the error 

2017-05-19 11:57:52 Extension missing: openssl Mailer Error: Extension missing: openssl

So i uncommented this in my php.ini 

extension=php_openssl.dll

Reran the script and got

Can anyone suggest what I'm doing wrong? Thanks

  • The important part: "certificate verify failed". This exact problem is very well known, covered in the PHPMailer troubleshooting guide that the error message links to, and has many duplicate questions on here. Please *read your error messages* before asking questions - it will get you the answers much faster! – Synchro May 19 '17 at 12:43
