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!

Blackberry Deleting Messages From My Pop3 Server

Asked by compsol1993 in Blackberry Operating System, Mdaemon, Email Clients

Hello,

We have an MDaemon server, and our users generally download their mail via POP3.  

One user has a blackberry (BIS), so we set his Outlook to leave a copy of messages on the server for 10 days.  We can also access his mailbox via the World Client (webmail app) built into MDameon.

One more piece of info, when a message is first recieved into Worldclient it's icon is a closed yellow envelope.  When it is downloaded with Outlook, it changes to a closed grey envelope.

Here is the problem:

When Outlook is turned on and downloading mail every 1 minute, all mail goes to Outlook, Blackberry does not get any mail.  When the state of the messages changes from the yellow icon to the grey one, I'm thinking that Blackberry is not interpreting this as a new message.

Even more odd, when Outlook is off, the Blackberry downloads mail, and deletes messages off of the server.  If I watch the MDaemon logging, I can see the BIS servers connect to our server, check for new mail, and then it issues DELE commands, all before the connection with BIS is closed.  I have included a portion of the logs in the Code window below.  Also, interesting, Blackberry checked this account 10 times since this message was received before issuing the DELE statement.  

One last piece, in the example below it leaves 3 messages.  These 3 were downloaded by Outlook, Blackberry never touches those.

Blackberry and AT&T both say this isn't possible, yet I see it in the log.  Is MDaemon mis-interpretting something from Blackberry and deleting messages?  The blackberry config does not have any settings to "leave message on server" for POP3.

Any thoughts?
Thanks
