DNSBL:To request

By rmessier ·
I have a situation where we use Group Wise for email, Novell software on the server, a LinkSys Router and our ISP is Comcast. The problem is I can't send a email message to anyone at, and using group wise. Now the weird thing is I can send the same message through AOL 9.0, through the same server, router and ISP using our AOL email account.
When I try to send a message using my domain name I get the following message.

The attached file had the following undeliverable recipient(s):

What does this message mean???
Anyone have any ideas where it might be broke. All the vendors point the finger at the other.

I could use your expertise on this one.

I have had a similar experience.
Your email server is on a black list by prodigy.
For some reason they think your email server is being used as a relay server.
You have to sent them an email to remove your mail server for the blacklist. in the process you will probably need to do some tests to verify that your mailserver is secure and not relaying email.
find out who they are using as the block list vendor and follow the procedures.

This at least gave me some direction. I appreciate the information you gave me. After further checking I found it 5 different places. How do I get it removed now?
