Do you see cases in the wild in which a client goes to the
trouble to do ESMTP AUTH and get it right and still can't manage
a correct domain name?

I can point out a case where this occurs. I use the Mac Version of Eudora (at the 6.4.2 level as I document by my injected X-Mailer Header) and it uses my LAN firewall IP Address ( in its EHLO not the DynDNS FQDN for my Connection (I run a private DNS Server what has the DynDNS host name connected to my rDNS PTR record so it is Accessible to but not used by the MUA).
