I've an issue resolving MX-Records for domains hosted at
[ns11,ns12].jimdo.com
The servers answer same questions in different ways:
dig @ns11.jimdo.com. MIRISSIMA.DE. MX +norec
-> NOERROR, no ANSWER
dig @ns11.jimdo.com. mirissima.de. mx +norec
-> NOERROR, answer
BUT: question for an A-Record are answered no matter upper- or
lowercase is used.
So my MTA try to deliver messages to the webserver :-/
Try doing some more queries. It's not based on the case of the query.
Looks like a load balancer and different versions of the zone. If you
query for the SOA you can get two different serial numbers.
