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!

SMTP Error:  #4.4.7 SMTP; 450 Service temporarily unavailable

Asked by doulos777 in Exchange Email Server, Email Servers, Simple Mail Transfer Protocol (SMTP)

Tags: Microsoft, Exchange Server 2007

Setup:  Microsoft Exchange Server 2007 running on Windows Server 2003 x64 (member server).  Network solutions hosts the web and email accounts.  Email is downloaded to the Exchange server using a POP3 connector.  Email is sent from the exchange server using a smart host setting.  Messages are relayed to Network Solutions to be sent to external domains.

We are currently having trouble sending to one email address.  This problem only started when i moved them to the exchange server - previously they had POP accounts setup in Outlook and used Network Solutions for email and had no trouble sending to the one address.  

I have listed the details of the error message below:
