HOWTO: send mail using perl on windows without sendmail

Q: How to send mail using perl on windows without sendmail?
A: You need Mail::Sender module and available SMTP Server

e.g.
Simple single part message

        $sender = new Mail::Sender {
                smtp => 'mail.yourISP.com',
                from => 'somebody@somewhere.com',
                on_errors => undef,
        }
                or die "Can't create the Mail::Sender object\n";
        $sender->Open({
                to => 'mama@home.org, papa@work.com',
                cc => 'somebody@somewhere.com',
                subject => 'Sorry, I\'ll come later.'
        })
                or die "Can't open the message: $sender->{'error_msg'}\n";
        $sender->SendLineEnc("I'm sorry, but thanks to the lusers,
                I'll come at 10pm at best.");
        $sender->SendLineEnc("\nHi, Jenda");
        $sender->Close()
                or die "Failed to send the message: $sender->{'error_msg'}\n";

yet another good option is Email::Sender module
usage:

  my $message = Email::MIME->create( ... );
  # produce an Email::Abstract compatible message object,
  # e.g. produced by Email::Simple, Email::MIME, Email::Stuff

  use Email::Sender::Simple qw(sendmail);
  use Email::Sender::Transport::SMTP qw();
  use Try::Tiny;

  try {
    sendmail(
      $message,
      {
        from => $SMTP_ENVELOPE_FROM_ADDRESS,
        transport => Email::Sender::Transport::SMTP->new({
            host => $SMTP_HOSTNAME,
            port => $SMTP_PORT,
        })
      }
    );
  } catch {
      warn "sending failed: $_";
  };
