Also try turning on Debug and see if you can catch the error.

my $smtp = Net::SMTP_auth->new($Servername, Port=>$Port, Debug => 1 );

You also might want to capture the transaction with ethereal or tcpick

Did you ever consider the other system dosn't support SMTP auth? Or the port it runs it on is different from the working system? Many systems run auth on port 587, but they can put it wherever they want.

Hi

In the system in which SMTP is not working thru perl, I tried with PHP. It works precisely with PHP. Here is the PHP code:

<?php

require("class.phpmailer.php");

$mail = new PHPMailer();

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

$mail->From = "from@somedomain.com";
$mail->AddAddress("to@somedomain.com");                  // name is op
+tional

$mail->Subject = "Here is the subject";
$mail->Body    = "This is the HTML message body";
$mail->AltBody = "This is the body in plain text for non-HTML mail cli
+ents";

if(!$mail->Send()) {
   echo "Message could not be sent.";
}
else {
   echo "Message has been sent";
}

?>

And, here is the debug=>1 output by Perl:

Also I have tried PLAIN & CRAM-MD5 apart from LOGIN

Any suggestion?

Thanks

Since the error is "Unknown callback: 'authname' ", I searched Net::SMTP and Net::SMTP_auth for 'authname' to see where it is used.

authname dosn't appear in the 2.08 version of Authen::SASL, but does in Authen-SASL-2.10, where it is metioned in the Changes file.

Maybe you need to upgrade to the latest Authen-SASL-2.10 ?
