When I'm trying to send mail through PHPMailer, i'm getting this error message. My code is below:

<?
require("phpmailer/class.phpmailer.php"); // First we require the PHPMailer libary in our script
$mail = new PHPMailer(); // Next we create a new object of the PHPMailer called $mail
$mail->From = "rajasekar.kcet@gmail.com";
$mail->FromName = "Rajasekar";
$mail->AddAddress("rajasekar.kcet@gmail.com"); // This is the adress to witch the email has to be send.
$mail->Subject = "First PHP Email message"; // This is the subject  of the email message.
$mail->Body = "Hi! \n\n This is my first e-mail sent through PHP."; // This is the actual email message
if(!$mail->Send()) // Now we send the email and check if it was send or not.
{
   echo 'Message was not sent.';
   echo 'Mailer error: ' . $mail->ErrorInfo;
}
else
{
   echo 'Message has been sent.';
}
?>

Make sure that you also include smtp class which comes with phpmailer:

// for mailing
require("phpmailer/class.phpmailer.php");
require("phpmailer/class.smtp.php");

Try with an address that is not gmail. They do not allow (as far as i know) smpt access to send mail from. I was doing a simple mail program last week and they also dont use default ports to send from and require that you transport across https

"Could not instantiate mail function" is PHPMailer's way of reporting that the call to mail() (in the Mail extension) failed. (So you're using the 'mail' mailer.)

You could try removing the @s before the calls to mail() in PHPMailer::MailSend and seeing what, if any, errors are being silently discarded.

In CentOS this might be caused by the SELinux policy. Execute the following code to see if it is enabled.

getsebool httpd_can_sendmail

You can enable it by calling the command below. The -P parameter makes it permanent.

setsebool -P httpd_can_sendmail 1
