still does not work. Do you know the ESMTP command sequence to send an
email
over TSL and Authenticate?

Well, maybe try something like this:
Use EHLO instead of HELO.
After EHLO and before MAIL FROM, send:

AUTH PLAIN xxx\r\n

where xxx is the base-64 encoding of a string consisting of a binary
zero followed by your account name (on the mail server), followed by
another binary zero, followed by your password. In Ruby, perhaps
something like

require 'base64'
Base64.encode64( "\000#{username}\000#{psw}" ).chomp
