flieckster has asked for the wisdom of the Perl Monks concerning the following question: 

#!/usr/bin/env perl

use strict;
use warnings;
use File::Find;
use File::Copy;
use Mail::Sender;
use Net::SMTP;
use Email::Send::SMTP::Gmail;
my $user = '####@####.#';
my $pass = '########';

my ($mail,$error)=Email::Send::SMTP::Gmail->new( -smtp=>'smtp.gmail.co
+m',
                                                 -login=>$user,
                                                 -pass=>$pass,
                                                 -port=> '25',
                                                 -verbose=>1,
                                                 -debug=> 1,);

my $subject = "Folder Counts";
my $to = '####@####.com';
$mail->send(-to=>"$to",-from=>"$to", -subject=>"$subject");
$mail->bye;

so the above code works on my one system just fine, i and loaded all the modules that are required for this simple script, yet when i run it i get the following error.

    Hi, something seems wrong with using using port 25 for TLS(SSL) connection. You can google for it yourself, but the port used for GMAIL SSL is port 465 or 587. You seem to be trying to connect to the standard mail port, and authentication fails.

    Here is a simple script to show you how a SSL connection is done, I know this works, but it's a different module. 

    #!/usr/bin/perl
use warnings;
use strict;
use Net::SMTP::SSL;                                                   
+              

# Implements the same API as Net::SMTP, but uses IO::Socket::SSL for i
+ts                
# network operations. Due to the nature of "Net::SMTP"'s "new" method,
+ it               
# is not overridden to make use of a default port for the SMTPS servic
+e.                
# Perhaps future versions will be smart like that. Port 465 is usually
+                  
# what you want, and it's not a pain to specify that. 

my $user = 'me@gmail.com';
my $pass = 'yeah_for_google';

#$server     = 'your-smtp-server';
my $server     = 'smtp.gmail.com';
my $to         = 'me@gmail.com';
my $from_email = 'me@gmail.com';
my $subject    = 'smtp-ssl-auth test';

my $smtps = Net::SMTP::SSL->new($server, 
                               Port => 465,
                               DEBUG => 1,
                               ) or warn "$!\n"; 

# I hust lucked out and this worked
defined ($smtps->auth($user, $pass))
    or die "Can't authenticate: $!\n";


$smtps->mail("$from_email\n");
$smtps->to("$to\n");
$smtps->data();


$smtps->datasend("From: $user\n");
$smtps->datasend("To: $to\n");
$smtps->datasend("Subject: $subject\n");
$smtps->datasend("Reply-To: $from_email\n");
$smtps->datasend("MIME-Version: 1.0\n");
$smtps->datasend("Content-Type: text/plain\n");
$smtps->datasend("\n");
$smtps->datasend("This will be the body of the message.\n");
$smtps->datasend("\n--\nVery Official Looking .sig here\n");
$smtps->datasend("\n");

$smtps->dataend();

#$smtps->quit();

print "done\n";

#You can alternatively just put everything in the argument to $smtp->d
+ata(),
#and forget about datasend() and dataend();

    Appears as though authentication is failing, which is resulting in -1 being placed into the $mail variable instead of the actual object.

    Try putting this immediately after the attempted object instantiation:

    die $error if $mail == -1;
