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!

Publishing SMTP Server ISA 2006

Asked by MrManderson in MS Forefront-ISA, Network Software Firewalls, Windows Networking

Tags: , , , ,

Hi All

Im having issues with incoming mail via ISA 2006, I have tried to publish our SMTP server however mail cannot be delivered to the exchange server via ISA.

The ISA server is setup in a 2NIC config Internal--ISA--Router--Inet

The external NIC has a manually assigned address from the router subnet, however microsoft states that when specifiying the external ip in the publishing wizard I should have the MX record IP (ie our static external ip) but this is not an option as the only ip I can select is the ip of manually assigned router ip on the external nic.

If I select in the networks tab external selected ip as all ip addresses is still get through. On the monitoring I cannot see any traffic coming through or being denied on port 25, however when i use mxtoolbox.com i get the following error"No connection could be made because the target machine actively refused it" I know the mx record is setup correctly so thats not an issue. Any ideas on how to get this working?

Please not I have already walked through the following to double check my config and everything is fine other than the external static ip.
