cox.net being rejected redux

hello,
  cgate-pro v6.1.9
  linux 4.1.15-8-default x86_64
  sending MUA: Apple mail (fairly recent version)

  So I renewed the license and upgraded to 6.1.9 from 5.4.11. And still
cox.net is being rejected; it is a different reason this time.
Previously it was because TLS negotiation failed.
  Now it is something about the EHLO command? I do not see what the
problem is. I tried a manual telnet session from both a local and remote
session, and got a happy response to both "EHLO [10.0.1.20]" and "EHLO
10.0.1.20":
"250-sma-inc.us we trust you [10.0.1.20]".
  Or maybe because I did not test in a secure session?
  I presume there is something in the response that the Apple Mail MUA
does not appreciate?
