View Full Version : SMTP Authentication & mail() - Help Required

06-04-2007, 04:48 PM
Being able to send emails through PHP is a fundamental part of the site, so I've been searching around and trying to come up with some code to authenticate with the SMTP server to send the email. What I have at the moment is code found on the Internet to perform this task using the PEAR module. I assume this module is installed as the php.ini 'include_path' setting is c:\php4\pear. Please correct me if I am wrong:

require_once "Mail.php";

$from = "MySite Mailer <admin@mysite.com>";
$to = 'mailto@mailto.com';

$host = "smtp.mysite.com";
$username = "smtp_user";
$password = "smtp_pass";

$headers = array ('From' => $from,
'To' => $to,
'Subject' => $subject);
$smtp = Mail::factory('smtp',
array ('host' => $host,
'auth' => true,
'username' => $username,
'password' => $password));

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) {
echo("<p>" . $mail->getMessage() . "</p>");
} else {

The error I am getting is as follows:

Fatal error: sendmail(): Failed opening required 'Mail.php' (include_path='.;c:\php4\pear')

I do not have a file called Mail.php in my directory listing, but I assumed this would be included by default through PEAR? I have not used PEAR before, so am unsure.

Any help would be much appreciated.

There should be a file in the PHP directory called go-pear.bat, just click on it, then follow the directions.

The pear setting in the include path is there by default. It does not mean that the pear framework or any specific pear class is installed.

A lot of servers don't have pear installed, so to create a stand a lone script that will work independent of what is present on the server, I recommend that you use the phpmailer class to do SMTP authentication - http://phpmailer.sourceforge.net/

Thanks for the quick reply. I have downloaded phpmailer and attempted to implement it. Although it is not returning an error, I am not receiving the email. Here is the code I am using (as part of a function):


$mail = new PHPMailer();
$mail->SetLanguage('en', 'language');

$mail->IsSMTP(); // set mailer to use SMTP
$mail->Host = "smtp.mysite.com"; // specify main and backup server
$mail->SMTPAuth = true; // turn on SMTP authentication
$mail->Username = "username"; // SMTP username
$mail->Password = "password"; // SMTP password

$mail->From = "myemail@gmail.com";
$mail->FromName = "MySite.com Mailer";
$mail->AddReplyTo("myemail@gmail.com", "MySite");

$mail->IsHTML(true); // set email format to HTML

$mail->Subject = $subject;
$mail->Body = $body;
$mail->AltBody = "";

echo "Mailer Error: " . $mail->ErrorInfo;
return 0;
} else {
return 1;

Does this code look correct? I've taken it from the PHPMailer documentation. If so, I'm guessing the problem lies elsewhere.

Thanks again,

are you doing this from your local computer ? and if so does your ISP block port 25 ? (mine (the biggest Australian ISP) does)

Hi there and thanks for the reply.

No, I'm executing the script from my webserver (hosting with Acecom). Since posting this thread up, I have actually received some test emails that have been sent - It just takes ~9 hours for them to arrive :confused:

I can't understand why.
