Here is some working code that uses Net::SMTP::SSL.

I would have had this this morning, but it took me a long time to figure out that the LocalPort parameter is necessary, or else IO::Socket::INET fails in _sock_info(). 

#!/usr/bin/perl -w
use strict;
use warnings;

use Net::SMTP::SSL;

my $smtp = Net::SMTP::SSL->new(
    'smtp.att.yahoo.com', 
    Hello => 'mymachine.org', 
    Port => 465,
    LocalPort => 0,             # Necessary
    Debug => 1);
die("smtp undefined: $@") if !defined $smtp;

my $acct_id = "your_full_userid_here";          # name@domain
my $acct_pw = "your_password_here";
my $dest_addr = "destination_email_address";    # name@domain

# Note two argument standard form.
my $auth_return = $smtp->auth($acct_id, $acct_pw);

# The mail() address must be your account's user id or else you'll get
# the dreaded "553 From address not verified" error.
# You cannot simply use $ENV{USER}.
my $mail_return = $smtp->mail($acct_id);

my $to_return = $smtp->to($dest_addr);
$smtp->data();
$smtp->datasend("To: $dest_addr\n");
$smtp->datasend("From: $acct_id\n");    # Could be any address
$smtp->datasend("Subject: Sending with Net::SMTP::SSL\n");
$smtp->datasend("\n");    # Between headers and body
$smtp->datasend("This is the body, line1\n");
$smtp->datasend("This is the body, line2\n");
$smtp->dataend();
$smtp->quit;

print "\nauth_return = $auth_return\n";
print "mail_return = $mail_return\n";
print "to_return = $to_return\n";
