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!

Lost incoming email to Exchange

Asked by nmonroe in Watchguard Firewall

Tags: , , , ,

I loose email from time to time incoming into my FireBox x550e (v10 firmware).

I am using the SMTP proxy to a static NAT IP address.  I am using Exchange 2007.

99% of other email comes through OK.  Larger email will give the following error in the logs:

Type                              Traffic            
DateTime                        2008-05-19 15:04:05
Disposition                        Deny
Source IP                        204.11.209.96
Source Port                        50540
Source Interface                  0-External- Wireless
Destination IP                        66.114.177.208
Destination Port                  25
Destination Interface                  Firebox
Policy                              Unhandled-External-Packet-00
Proxy Action                        NONE
Message                              denied

Please advise.  I am not sure what to do.  This is irritating my customer that we can not receive email with larger attachments.
