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!

Is my server an open relay?

Asked by sminfo in Postfix

Tags: postfix

My scenario:

I have a lot of postfix servers, each one, use to sent mail directly  to internet, so It's difficult to monitor them.
What I want?

Put all postfix's of my servers to send all their external mail  to an smarthost server in my network.  I mean, the smarthost must receive ONLY mail from my servers and relay them mail to internet. Remember I have a lot of different servers and domains so I don't know how to configure this smarthost becasuse in some way it's becoming an open relay.

My question:
How can I set up a secure smarthost to my network that receive ONLY from my servers and  relay all mail directly to Internet?
