Setting SMTP details for php mail () function [dup

Send email using the GMail SMTP server from a PHP page 13 answers

I have been looking for an answer and tried many things to this problem.

My script works fine on my webhost but when moving it to an other dedicated server the mail never gets delivered. Now i need to set the SMTP server but don't get it right.

Using Gmail apps btw. This is how the code looks like.

<?php

if(!$_POST) exit;

$email = $_POST['email'];


//$error[] = preg_match('/\b[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i', $_POST['email']) ? '' : 'INVALID EMAIL ADDRESS';
if(!eregi("@",$email )){
    $error.="Invalid email address entered";
    $errors=1;
}
if($errors==1) echo $error;
else{
    $values = array ('name','email','telephone','message');
    $required = array('name','email','telephone','message');

    $your_email = "xxx@example.com";
    $email_subject = "New Messag: ".$_POST['subject'];
    $email_content = "New message:\n";

    foreach($values as $key => $value){
      if(in_array($value,$required)){
        if ($key != 'subject' && $key != 'telephone') {
          if( empty($_POST[$value]) ) { echo 'PLEASE FILL IN REQUIRED FIELDS'; exit; }
        }
        $email_content .= $value.': '.$_POST[$value]."\n";
      }
    }

    if(@mail($your_email,$email_subject,$email_content)) {
        echo 'Message sent!'; 
    } else {
        echo 'ERROR!';
    }
}

$mail->Mailer = "smtp";  
$mail->Host = "ssl://smtp.gmail.com";  
$mail->Port = 465;  
$mail->SMTPAuth = true; // turn on SMTP authentication  
$mail->Username = "user@gmail.com"; // SMTP username  
$mail->Password = "password"; // SMTP password 

?>

So how do i set the SMTP settings right?

回答1:

Under Windows only: You may try to use ini_set() function^Docs for the SMTP^Docs and smtp_port^Docs settings:

ini_set('SMTP', 'mysmtphost'); 
ini_set('smtp_port', 25);

Check out your php.ini, you can set these values there.

Here's the description in the php manual: http://php.net/manual/en/mail.configuration.php

If you want to use several different SMTP servers in your application, I recommend using a "bigger" mailing framework, p.e. Swiftmailer

Try from your dedicated server to telnet to smtp.gmail.com on port 465. It might be blocked by your internet provider
