Perfect, thanks! billmail.scconsult.com is not delegated from scconsult.com
(has no SOA or NS), and sccconsult.com is delegated from .com (of course),
with SOA and NS.
Bonus points: billmail has SPF.
Same concept, but a bit different (also has SPF, DANE, ...):
d.stoecker.eu -> 10 mail.stoecker.eu.
Subdomains for members of the family :-) Using only one MX for these
and the main domains.
Usually works fine except:
* Some clever web-interfaces assume that e-mail addresses can only have one dot
* Some more clever web-interfaces assume that a single letter before the dot
isn't ok.
So it's not always possible to use the addresses.
