The fix is to tell your postfix to not offer STARTTLS in the EHLO response, using smtpd_discard_ehlo_keyword_address_maps http://www.postfix.org/postconf.5.html#smtpd_discard_ehlo_keyword_address_maps

something like:

# main.cf
smtpd_discard_ehlo_keyword_address_maps =
   cidr:/etc/postfix/discard_ehlo_keyword_map.cidr

# /etc/postfix/discard_ehlo_keyword_map.cidr
216.109.104.12  starttls

I am reporting back to say it works well.

One more question. In the maps file is it possible to use a hostname instead of an ip address?
