Hi all

I know, this is a silly question. But I have to be certain because
a number of people are involved.

===
$ nslookup
> set q=mx
> MYSLD.TLD

Server: 192.168.0.1
Address: 192.168.0.1#53

Non-authoritative answer:
MYSLD.TLD mail exchanger = 5 \
spamfilter.MYSLD.TLD.MYSLD-TLD.ch.
MYSLD.TLD mail exchanger = 10 \
mail.MYSLD.TLD.MYSLD-TLD.

Authoritative answers can be found from:

The problem is that the MYSLD.TLD pattern repeats, mail to
users@MYSLD.TLD get rejected due to this.

My quesion is, whether the problem is just a missing "dot" in MX?
IN MX 5 spamfilter.MYSLD.TLD
^dot here
IN MX 10 mail.MYSLD.TLD
^and here
mail IN A IP-ADDRESS
spamfilter IN A IP-ADDRESS

And also I'm curious, why there is nothing after the line "Authoritative
answers can be found from:".
