SMTP Authentication problem - perl

Question

I'm writing a simple mail client in Perl, that uses SMTP to log in a Mail server, and from there sends a mail to another E-mail address (on different host). I use raw SMTP commands, because strawberry perl doesn't come with SASL.pm which is needed in order to authenticate. However, when the script tries to authenticate itself, it fails. I tried 'AUTH LOGIN' and 'AUTH PLAIN' mechanism but no luck. Here is an example:
EHLO example.com
AUTH LOGIN
YWxwaGE=
cGFzc3dvcmQ=
MAIL FROM:<alpha#example.com>
RCPT TO:<beta#betadomain.com>
DATA
Subject: sample message
From: alpha#example.com
To: beta#betadomain.com
Greetings,
Typed message (content)
Goodbye.
.
QUIT
EOT
"YWxwaGE=", "cGFzc3dvcmQ=" are the user and password encoded in Base64. Whatever I submit the server always complains that either the username or the password is wrong. What do I do wrong?

Why not just install a module that supports SMTP with SASL? One of the advantages of Strawberry Perl is that you can easily install modules from CPAN.
For example, Email::Simple and Email::Sender:
use strict;
use warnings;
use Email::Sender::Simple qw(sendmail);
use Email::Simple;
use Email::Simple::Creator;
use Email::Sender::Transport::SMTP;
my $email = Email::Simple->create(
header => [
To => 'beta#betadomain.com',
From => 'alpha#example.com',
Subject => "sample message",
],
body => "Greetings,\nTyped message (content)\nGoodbye.\n",
);
my $transport = Email::Sender::Transport::SMTP->new({
host => 'smtp.example.com',
sasl_username => 'foo',
sasl_password => 'bar',
});
sendmail($email, { transport => $transport });
