The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Could somebody please explain this message to me:

      You do not have permission to send to this recipient.  For assistance, contact your system administrator.

        < dmzpostal.cckh.com #5.7.1 SMTP; 550 5.7.1 Sender ID (PRA) Not Permitted>

The company that we are trying to email (cookcommunications) tells us that the issue is on our side, we think it is on their side.  The funny thing is that this does not happen all of the time..it is random but in blocks of time.  

dmzpostal.cckh is our mailsender server running on Linux.  Our Exchange Server is 2003 SP2.

I also tried to do this through DOS and recieved the following message:

Connected to ccm-mail.ccm.ccm-net.org.
Escape character is '^]'.
220 ccm-mail.ccm.ccm-net.org Microsoft ESMTP MAIL Service, Version: 6.0.3790.1830 ready at  Thu, 22 Mar 2007 07:47:14 -0600

Not quite sure what this means but it looks like their mail server is not accepting our emails and they are pointing the finger back at us...neither of us have Sender ID enabled

Can someone clear this up for me?

Thanks so much in advance
