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!

Getting Spam After Upgrade of IMSS from 5.7 to 7.0

Asked by kaos_theory in Anti-Spam Email Software, Email Servers

Tags: , ,

Last Friday, we upgraded IMSS from 5.7 to 7.0.  Additionally, we use Postini for both in and outbound email spam protection, so all of our message headers inbound have a Postini "footprint" as it were.  

However, after the upgrade to 7.0, we have been getting spam email messages that simply say:

From:  postmaster@localhost
Subject:  Delivery Final Failure Notice
Body:  Can not deliver the message you sent.  Will not retry.

The header of the message has no Postini relays mentioned, and is in fact rather short, with a message id of <messageid@127.0.0.1>  but the message itself came FROM our IMSS server to our back-end Exchange Server and the postmaster account is NOT the one specified in the IMSS notification settings either.

IMSS is configured to only allow relaying to our internal Exchange server and our Postini relays.  What's different about this is that in 7.0, it lists 127.0.0.1 as a valid IP to allow relaying.  Trend Micro says we cannot remove it (i tried, twice, it keeps coming back) -- they say it's the way the program operates, but I think it's a little weird that 127.0.0.1 just so happens to be in the message ID of these spam messages too....

Any advice would be appreciated -- am I barking up the wrong tree?  Or is Trend really screwing me over in this new version??  Confused and frustrated with their technical support right now :( Start Free Trial
