if you want a 'flat' public domain name space for the company, then these are
your only options. as you note, #3 is a noisy heuristic, not a solution.
my own view is that <sub>.company.tld (eg, us.example.com or jp.example.com)
still retains essential identity homogeneity. but it's not unreasonable that
an organization would want it *entirely* homogeneous.
unfortunately, all public routing to email servers is based only on domain
names, so the domain name has to contain differential information if
differential routing is needed.
ldap can only be a factor after the mail server gets the full email address.
