You are using a CNAME on the right hand side of an MX record. you must use
the real name associated with an A record.
You have two choices.
Change
mail1.teliamobile.dk. 86400 CNAME ns.teliamobile.dk.
mail.teliamobile.dk. 86400 CNAME ns1.teliamobile.dk.
(I don't see this second line but I think you have been editing)
To
mail.teliamobile.dk. 86400 A 62.44.158.10
mail1.teliamobile.dk. 86400 A 62.44.158.11
OR
Change
teliamobile.dk. 86400 MX 40 mail.teliamobile.dk.
teliamobile.dk. 86400 MX 30 mail1.teliamobile.dk.
To
teliamobile.dk. 86400 MX 40 ns.teliamobile.dk.
teliamobile.dk. 86400 MX 30 ns1.teliamobile.dk.

Hi,
I am getting blind (meta-speaking), so help me understand this:
The problem is this:
!!! teliamobile.dk MX host mail1.teliamobile.dk is not canonical
Here you get it all: Note that I am not using mydomain.com, this is the
real thing.
We just started this so we will soon be hiding the 10. names, but for now,
we do not like the warning about
the 'not canonical'. I re-created the scenario on my own system, and if I
left out the trailing
domain on mail1 on the CNAME statement, I did not have this warning.
B.t.w. it does not take long for hackers to track newly created and
registered zones. We have loads
of tries in our logs. Why? Is it kids that have nothing else to do than
try to infiltrate and make harm
on businessees?
Advise on the 'non canonical warning', pls.? And what else you might
suggest.
Thanks,
/Johnny

Explanations on a few of the RR's (Resource Records). Those not listed can
be found in the RFC's, but you probably don't need them if you don't know
which are what.
MX = Mail eXchanger - with preference. The lowest number handles the
mail.
A = Address (IP-number).
AAAA = Address (IP-number, v6).
CNAME = Canonical name - i.e. an alias.
NS = Name Server - what servers are authoritative.
HINFO = Host Information.
WKS = Well Known Services.
The numbers listed before each RR is the time left for that record in the
cache. If the nameserver is authoritative on that specific record, this
number will not
decrease as time goes by.
Zonetransfer (AXFR)
Please note that not all ISP's allow zonetransfer and that zonetransfer of
a domain/reverse domain only makes sence if a zone HAS been defined. You
can
ONLY zonetransfer a zone from one of the authoritative nameservers.
