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!

Email bounces back with 550 5.7.1 SPF unauthorized mail is prohibited

Asked by AnthonyJK in Simple Mail Transfer Protocol (SMTP), Email Software, Miscellaneous Software

Tags: SPF, SMTP, Postini, Email

Hello, I have a client trying to email my boss and keeps coming back with the error below. It looks like its on our part but not sure how to fix it. I researched it but found pretty much nothing. Our email is hosted with GoDaddy and then we have Postini as our Spam Filtering. I looked for any SPF settings on Postini but did not see anything. Thanks for any help.
