Of course it helps, thank you. :-)

Uhm. I actually want to have a standards compliant DNS setup, but setting a
an MX record for each subdomain (I don't know them in advance ...) looks a
bit time-consuming. I hoped it was possible to specify wildcards for both
the A and the MX types. But the day will come when I'll separate mail from
web, and then I've got to fix all that afterwards since I cannot just
change the A record of my MX host. Isn't there another smart way to come
around that?
