[For accountability, I'd use] a domain name. One reason is that

being procrastinated every few months, since November 2008.) By
contrast, domain registrants often have whois records pointing to them.
I think I'm catching on: you want to link the MTA to a _registered_
domain.
Yup. However, no official registration exists for, say, us.ibm.com or
it.ibm.com. The latter two ones happen to have different hostmaster
addresses, therefore it would not be correct for them to share the same
accountability token "ibm.com". I can only trust the DNS about the
legitimacy of such subdomain delegations.
ibm.com isn't an email domain. At least, it's not one they use to send
email. They do send email from @us.ibm.com addreses.
