Inbound Email ROUTING problem with Recepient staus 550.5.1.1 RESOLVER.ADR.RecipientNtFound in newly Exchange 2007 installed in split zone

I have completed the installation os a 2008 domain controller, a Win 2008 webserver, and an Exchange 2007 server on separate servers.
I used ABC.LOCAL as local DNS (Zone), then installed Exchange 2007 server, then added a 2nd zone as ABC.NET (My registered domain with Godaddy.com), I modified the Default Reciever to allow anonymous senders.
Inbound emails pass the RECIEVE status for the address USER@ABC.NET, then I see it in the next line (after I run Message Tracking Results) the ROUNTING staus is FAIL with the following status:  " 550.5.1.1 RESOLVER.ADR.RecipientNotFound"
I also have problems with outbound emails too, but I think if I get inbound Relay to work the other one will be ok or at least much easier. Whatever is causing the problem should be coming from the split (Internal and external) zones.
I checked and searched the web for a solution for more than 10 hours and still facing the same problem.

I appreciate any help in this matter very much.

I did create accepted domain named ABC.NET, but I don't know to stamp it to user's address.
Could you please explain to me how to do it?

Thanks

Jay

This would be an automatic process unless exchange is broken somewhere.

Go to EMC > Receipients > Go to properties of the mailbox and check if you have the user with correct email address to it.

if it's not there then manually add the email address and first test internal mailflow. Try to send email to that address

Thank you so much for your help.

As soon as I sent you my comment with regards to Stamping, I went to EMC and modified the Default policy under Organization/HubTransport as the following:
%m@ABC.NET
@ABC.LOCAL

I tested it by sending an email from Gmail it worked. The only problem remains is outbound email. I tried to reply back to my gmail account, I DO NOT SEE THE REPLY IN MY GMAIL.
I should mention that I am using a DYNAMIC PUBLIC IP. I heard from MXTOOLBOX that almost all of Dynamic Public IPs are listed as RPBL.

Thanks

Hi,

.net and .local domains will not be resolvable on the internet. you need something like .com and also emails from dynamic ip will be rejected as spam.

I think I had comcast.net email account a few years ago for my personal email service.
To my limitted knowledge .NET is not at the same category with .LOCAL
I have my domian registered as lets say "ABC.NET" and "ABC.COM": is not available.

Not yet, but I just tried. I get an error saying telnet is not recognized. Should I move back to the root then type telnet?

no, you need to install telnet client from server manager.

Connecting to gmailMxRecord:25 (press Esc to cancel)...

[TELNET] FAIL: Host not found. (The requested name is valid, but no data of the requested type was found.)

Do I have to run it on my exchange server?

Hi

You need to establish telnet sesion from hub transport server if you are not able to establish a connection then try with some domain to narrow down the issue but if u still not able to connect to any domain then check ur firewall and find out why outbound smtp is blocked

Hello,

As I mentioned before, I ran MxToolBox on my public IP (74.103.10.158) and found out it is block listed as SPAMPBL in Spamhause.org. I called MxToolBox about it. They told me because it is a Dynamic IP, Verizon has them listed blocked via SPAMHAUSE.
Going back to TELNET, I was able to telnet my mail server on port 25 (It is internal). I also sould mention that My Exchange server has all roles installed on it, only one server.
I also called Verizon Fios Internet service department to see how much it'll cost me to have a static IP. Unfortunately it costs $110 permonth and I can not afford it.
On my firewall I have port 80 open for a different server (my web server), and ports 443 and 25 for Exchange email server.
Any advise to remedy this obstacle would be much appreciated.

Jay

It quite difficult because most of the messaging system subscribe to rbls, may be you can look into hosted solutions or some other isps for small home office buisness

It is not listed in RBL, but in PBL. I created a VMware virtual environment with several servers on it. My goal is to use it as a useful lab at home to practice and test several applications and softwares.
I have my Internet access as part of Fios package.
Question: If the public IP I mentioned above is block listed as PBL, does it mean I should not be able to Telnet through port 25?
I understand the outbound emails won't be delivered. But why port 25 isn't working for Telnet?

Thanks

RBL means real time blacklisting, i generally use that term to cover all the spectrum.

You may or may not connect to port 25 on remote server due to your ip being listed. There are security in place which may not even allow you to connect to port 25, depending upon the solution remote domain is using.
