Email getting blocked.
Currently our corporate users are blocked from being able to email service@abc.com. This creates an issue if we need to forward an email from that address to a corporate user who wants to reply back. All corporate users should be able to email this address which is a shared mailbox used by online customer service.
Our environment is Server 2003 for Exchange and running Exchange 2007. The email service@abc.com is hosted by Godaddy. The issue is that we can receive emails from service@abc.com but when we try to send an email we are getting a denied sent due to restrictions. Our Websense is not blocking it.
See below (Bounce back message). I modified a few things in the bounce back message for security reasons. Anyone who has ever troubleshot this issue, please shed some light on how to fix or troubleshoot. Thank you.

Are you using SMTP namespace sharing - hosting the same SMTP domain in your exchange organization and with GoDady? (Sorry, the modified header information is confusing)
Is GoDady allowed your Exchange server to receive emails? Do a simple telnet test from your transport server to GoDady smtp server to check this.
Telnet smtpserver_ip 25
once connected, you get a banner. Else you may see connection refused/timed out...
Thanks,
Veera.

Here is the actual bounce back message. I am not to much of an email admin, so please go help guide me step-by-step. I am actually helping another admin research this. How would I do the telnet or validate that SMTP is installed?

Im confused - can you explain who is trying to send what? it sounds like a spam filtering issue...

Still no luck.
If you are sending outbound to service@abc.com (which is NOT your domain) then what is most likely happening is that you are on some type of DNS blacklist OR you do not have a proper SPF record.
For checking the DNS blacklist I would use mxtoolbox.com. They will tell you what you are blacklisted on, and how to remove it.
As for the SPF I would recommend going through this tool here to make an SPF record for you: http://www.spfwizard.net/. Its pretty accurate and will be RFC compliant (for the most part).
I doubt this is an issue with the content of the message or the attachment, as you usually wouldn't get that NDR back (SMTP 4.4.1)
If you want you can check, or you can respond back with the domain name and I can double check the configuration with you.
