116592 DNS set up for main server

We run our own dedicated server and have dns issues on the main domain that sends mail for our clients.

We asked our server team to look at this and were quoted $80 which we think is totally unreasonable being they should have set the server up correctly in the first place.

We would also like help setting up an spf for this domain

Here are the errors on the dns check

------------------------------------------------

Glue at parent nameservers

WARNING. The parent servers (I checked with tld4.ultradns.org.) are not providing glue for all your nameservers. This means that they are supplying the NS records ([url removed, login to view]), but not supplying the A records ([url removed, login to view]), which can cause slightly slower connections, and may cause incompatibilities with some non-RFC-compliant programs. This is perfectly acceptable behavior per the RFCs. This will usually occur if your DNS servers are not in the same TLD as your domain (for example, a DNS server of "[url removed, login to view]" for the domain "[url removed, login to view]"). In this case, you can speed up the connections slightly by having NS records that are in the same TLD as your domain.

All nameservers report identical NS records

WARNING At least one of your nameservers did not return your NS records (it reported 0 answers). This could be because of a referral, if you have a lame nameserver (which would need to be fixed).

Lame nameservers

ERROR You have one or more lame nameservers. These are nameservers that do NOT answer authoritatively for your domain. This is bad for example, these nameservers may never get updated. The following nameservers are lame

Missing nameservers 2

Nameservers on separate class C's

WARNING We cannot test to see if your nameservers are all on the same Class C (technically, /24) range, because the root servers are not sending glue. We plan to add such a test later, but today you will have to manually check to make sure that they are on separate Class C ranges. Your nameservers should be at geographically dispersed locations. You should not have all of your nameservers at the same location. RFC2182 3.1 goes into more detail about secondary nameserver location.

h NS record leakage

Your DNS servers leak stealth information in non-NS requests

Stealth nameservers are leaked [B.ROOT-SERVERS.NET.]!

Stealth nameservers are leaked [C.ROOT-SERVERS.NET.]!

Stealth nameservers are leaked [D.ROOT-SERVERS.NET.]!

Stealth nameservers are leaked [E.ROOT-SERVERS.NET.]!

Stealth nameservers are leaked [F.ROOT-SERVERS.NET.]!

Stealth nameservers are leaked [G.ROOT-SERVERS.NET.]!

Stealth nameservers are leaked [H.ROOT-SERVERS.NET.]!

Stealth nameservers are leaked [I.ROOT-SERVERS.NET.]!

Stealth nameservers are leaked [J.ROOT-SERVERS.NET.]!

Stealth nameservers are leaked [K.ROOT-SERVERS.NET.]!

Stealth nameservers are leaked [L.ROOT-SERVERS.NET.]!

Stealth nameservers are leaked [M.ROOT-SERVERS.NET.]!

Stealth nameservers are leaked [A.ROOT-SERVERS.NET.]!

This can cause some serious problems (especially if there is a TTL discrepancy). If you must have stealth NS records (NS records listed at the authoritative DNS servers, but not the parent DNS servers), you should make sure that your DNS server does not leak the stealth NS records in response to other queries.
