I want to write a script to send emails via my server's SMTP server. The server requires SMTP authentication.

But I've problem completing this SMTP authentication. When the script is ran, the server gave out an error message: 535 Incorrect authentication data.

Could you kindly help fix the problem?

Thanks.

Here's the script (only listing the SMTP authentication portion) 
#!/usr/bin/perl

use Net::SMTP_auth;

$smtpserver = 'mail.myserver.com';
my $ServerAccount = "mailbox\@myserver.com";
my $ServerPwd = "mb128com";

my $smtp = Net::SMTP->new($smtpserver, Hello => "myserver.com",  Debug
+ => 1);
$smtp->auth('CRAM-MD5', '$ServerAccount', '$ServerPwd');

exit;

The followings is the output when the script is ran:

Net::SMTP>>> Net::Cmd(2.29)
