PHPMailer not sending mail

[nandhini-rajanayagam]

I can't able to send mail using phpmailer from windows server 2012 , but i can able to send from local machine using local server. Can any body help me?

require("PHPMailer/PHPMailerAutoload.php");
$Mail = new PHPMailer();
$Mail->IsSMTP(); // Use SMTP
$Mail->Host = "mail.company.in";
$Mail->Port = 25;
$Mail->SMTPDebug = 6; // 2 to enable SMTP debug information
$Mail->SMTPAuth = false; // enable SMTP authentication
$Mail->AuthType = 'PLAIN'; // enable SMTP authentication
$Mail->SMTPOptions = array(
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => true
)
);
$Mail->Username = "noreply.company";
$Mail->Password = "456546";
$Mail->Priority = 1; // Highest priority - Email priority (1 = High, 3 = Normal, 5 = low)
$Mail->CharSet = 'UTF-8';
$Mail->Encoding = '8bit';
$Mail->Subject = 'Test Email Using Gmail';
$Mail->ContentType = 'text/html; charset=utf-8\r\n';
$Mail->From = '[email protected]';
$Mail->FromName = 'Test';
$Mail->WordWrap = 900; // RFC 2822 Compliant for Max 998 characters per line

$Mail->AddAddress( $to ); // To:
$Mail->isHTML( TRUE );
$Mail->Body = $content;
$Mail->AltBody = $content;
$Mail->Send();
$Mail->SmtpClose();

if ( $Mail->IsError() ) { // ADDED - This error checking was missing
return FALSE;
}
else {
return TRUE;
}

I got the following error message,

domain doesn`t exist (mail.company.in: Non-existent domain), if mail server is in your localhost, try using localhost, also for all information's you have link in exception:

P.S. Reduct/remove password, don`t ever send your password (credentials).

You're doing a whole load of things wrong, but the fundamental thing is that your server does not support encryption. That's bad. As for the other things:

require("PHPMailer/PHPMailerAutoload.php");

This means you're using a very old version. Upgrade.

$Mail->SMTPDebug = 6; // 2 to enable SMTP debug information

There is no debug level 6. You only need 2 to diagnose this problem.

$Mail->SMTPAuth = false; // enable SMTP authentication
$Mail->AuthType = 'PLAIN'; // enable SMTP authentication

You're disabling authentication (so the AuthType doesn't matter), then later providing a user name and password unnecessarily.

$Mail->SMTPOptions = array(

Don't do this; it's dangerous. Fix your server instead.

$Mail->Encoding = '8bit';

You don't need to set this.

$Mail->ContentType = 'text/html; charset=utf-8\r\n';

Your'e trying to undo things that PHPMailer is doing for you; don't do this as it will likely break your messages. Your'e already calling isHTML(), which takes care of content-type for you, and correctly.

$Mail->WordWrap = 900; // RFC 2822 Compliant for Max 998 characters per line

WordWrap is not the same thing as line length, and only applies to plain text messages. You don't need this, and it's not doing what you think anyway.

if ( $Mail->IsError() ) { // ADDED - This error checking was missing

Don't check for errors like this. Check the return vale of send(), as all the examples do.

i just use dummy domains with dummy user id password
