Hi,

I have some error and some warning messages to my dns settings at:
http://www.nabber.org/projects/dnscheck/?domain=dictzone.com

Can you help me, how to fix them?

Public AXFR Transfers Denied - WARN
This is on Linode's to-do list. Nothing for you to do. Not a huge security risk.

Nameservers Report Identical NS Records - FAIL
This is probably because ns1 is not responding (see below).

Nameservers Respond - WARN
ns1.linode.com is not responding. Linode will fix this.

TCP Allowed - WARN
ns1.linode.com is not responding to UDP or TCP. This will go away once the server is back up.

SOA Minimum TTL - WARN
SOA TTL is set to 24 hours. Not compliant with RFC2308 but everyone does it and it's not a problem.

Multiple MX Records - WARN
You only have one MX record. If your mail server is down, mail cannot be sent to an alternative server. Delivery will fail if the server stays down for a long period. Senders will get messages about delayed delivery. Consider setting up a backup mail server. I use ZoneEdit to do this - they store email and forward it when your server comes back up - $10.95 per year.

SPF Record Present - WARN
You should consider adding a Sender Policy Framework (SPF) record (type = TXT). SPF allows mail software to identify and reject messages that are not authorized to have your domain name used in the SMTP MAIL FROM command. This helps to get mail through to Gmail and other big mail systems and discourages spammers from using your domain as a forged return address.

You should consider and then reject adding an SPF record to your domain:

Thanks for fast answers.

In this case, there's nothing to do with my DNS.
