these are some of the fails I get from DNSstuff.com, is there

Is that the domain (liebertpub.com) you are trying to send to? I looked it
up here and it points to 4 different mail servers:
===================================
liebertpub.com
Click to expand...
Server: ponyexpress.bandwidthpros.com
Address: 208.47.39.10

Non-authoritative answer:
liebertpub.com MX preference = 400, mail exchanger =
liebertpub.com.mail4.psmtp
..com
liebertpub.com MX preference = 100, mail exchanger =
liebertpub.com.mail1.psmtp
..com
liebertpub.com MX preference = 200, mail exchanger =
liebertpub.com.mail2.psmtp
..com
liebertpub.com MX preference = 300, mail exchanger =
liebertpub.com.mail3.psmtp
..com

liebertpub.com.mail4.psmtp.com internet address = 63.240.165.100
=================================

I looked up netlabs.net and it seems ok:
set type=ns
netlabs.net
Click to expand...
Server: ponyexpress.bandwidthpros.com
Address: 208.47.39.10

Non-authoritative answer:
netlabs.net nameserver = ns1.netlabs.net
netlabs.net nameserver = ns2.netlabs.net

ns1.netlabs.net internet address = 216.116.128.3
ns2.netlabs.net internet address = 216.116.128.4

but I looked up oceanconputer.com and got this below. Now what is under your
name server tab for the netlabs.net DNS server and what is under the
nameserver tab under the machine hosting oceancomputer.com?
===================================
oceancomputer.com

Server: ponyexpress.bandwidthpros.com

Non-authoritative answer:
oceancomputer.com nameserver = ns1.netlabs.net

Obviously the message is self explanatory. You can;t create a CNAME for a
nameserver. SPecifically, you need to create a host record (an A record)
under oceancomputer.com called ns1 and give it the actual IP address.
Against the RFC to create a CNAME for it and point it to ns1.netlabs.net or
whereever it;s pointing.

What is the domain here newman.liebertpub.com or liebertpub.com?

This is not the reason you can't send the mail but your DNS zone needs to be
cleaned up.

You need an "A" host named NS1 with your DNS public IP address instead of
the CNAME pointing to mail.oceancomputer.com.
Then you need to go to the Name Server tab on your oceancomputer.com Forward
lookup zone and add the NS records for all your name servers and remove the
incorrect NS record.
You also need to correct your RP record and primary name server record on
the SOA tab.
 
P> what does this mean?

It means that the domain name "newman.liebertpub.com." does not
exist. And it is correct. It doesn't.

As the error message says, check that the mailbox name that you
were given is actually correct.
 
Liebertpub.com is my domian, the domains that failed are
bedford.k12.ny.us and oceancomputer.com

thanks

I see. Did you follow the suggestions by Kevin and I to clean up the records
and remove the CNAME records?

Apparently also, you have multiple DNS servers. These are not apparently all
on the two DNS servers that you originallymentioned, whcih are the ns1 and
ns2.netlabs.net. I was assuming that they were all on one server, but
lookups indicate otherwise. If the nameserver listed in the registrar does
not have it's name under the nameservers tab, this is part of what's going
on. So frankly, not sure if they should all be on one DNS server or not, so
I'm getting a bit confused here. For example, I looked up oceancomputer.com
at the registrar, and it gave me this info:

NS1.OCEANCOMPUTER.COM 216.116.139.130
NS1.NETLABS.NET 216.116.128.3
NS2.NETLABS.NET 216.116.128.4

and I did a lookup on it:
oceancomputer.com
Click to expand...
Server: ponyexpress.bandwidthpros.com
Address: 208.47.39.10

Non-authoritative answer:
oceancomputer.com nameserver = ns1.netlabs.net
oceancomputer.com nameserver = ns2.netlabs.net
oceancomputer.com nameserver = ns1.oceancomputer.com

Now these 3 servers MUST contain the same exact info. Also, their name
server tabs need to have each other listed in there or you'll get those
errors. As for the CNAME errors, well, that;s self-explanatory. Delete the
record and creeate an actual A record for ns1 and ns2 under netlabs.net and
create an ns1 under oceanconputer.com.

Liebertpub.com is my domain
newman is my E2K server
oceancomputer.com and bedford.k12.ny.us are the domains I"m trying to

The information from DNSSTUFF.com is about thier domains.

OK, I think I get the picture now, if you have Exchange set up to deliver
mail directly it is being refused due to there is no look up on your mail
server host name and probably no reverse lookup on its IP address either.

I notice that you are using smart hosts for your incoming mail and you are
probably going to have to use a smart host for your outgoing mail, too. Most
likely your current incoming smart hosts are set up so you can use them for
out going mail.

Since other mail servers cannot do a lookup on your mail server name or IP
address a lot of mail servers will reject it. If you add a host for its name
and a PTR record for its IP this will probably get you going so long as your
IP isn't on too many open relay lists, at least the major ones such as
orb.org.
