[Gllug] speaking of DNS server setups...

[Benedikt Heinen]

Is it possible, with bind9 or another name server, to specify part of a 
domain name as a wildcard?

e.g.  I would like to define the same setup for all *.foo.net hosts, so 
that www.a.foo.net, www.b.foo.net, ... www.zyx-cba.foo.net all point to 
the same host?

Second, and now it gets more interesting, can I specify exceptions?

e.g. turning off bar.foo.net but still allowing all other *.foo.net 
permutations?



Finally, and now we're leaving bind's domain - can I set up postfix in a 
way to allow to receive email for all those, without adding all 
individual names to the mydestination and/or relay_domains list?

(obviously, if I can specify to not allow specific combinations in DNS, I 
am not to worried if postfix wouldn't allow to block specific entries 
within those; after all, who should find the postfix server, once the MX 
record for bar.foo.net is gone?)
