• Can anyone provide a few examples of "Unknown reason" rejections

    By Gavin J Bollard 2 decades ago

    Hi,



    I'm very impressed with Mail Analysis. I've been "hassled" by management over blacklisting and content filtering issues and have been able to use it to demonstrate that we aren't rejecting business emails.



    Unfortunately they have been asking questions about the "Unknown reason" blocks. Especially since these are so high.



    Most of our content filtering is done by Symantec, but I still have a mail rule on the server to reject a lot of different file types. This is to reduce virus broadcasts.



    I've looked through the logs but I can't see a number of mail rule rejections that corresponds to the number of "Unknown reason" rejections.



    As I have to report to management, I'd really appreciate some more examples of what constitutes an unknown reason.



    Thanks.

    • Domino logging problem :-(

      Hi,



      first of all thanx for using our program.

      The unknown reason is due to a diffucult way of understanding what is rejecting the mail.

      For example:



      create a server rule for rejecting exe file.

      send a mail with a exe attachment.

      take a look at the log.nsf: no entry that can help us understanding it's server rule 1 causing the rejecting.



      This is why i have a "unknown reason" counter.



      Sorry I know it doesn't help much, but it's a Domino logging problem :-(



      Regards,



      Simone

      Hi Gavin,



      As Simone said it can be because of maile rule rejection (but it's fixed in 1.35), but also from a mail server that initiate a smtp session and terminates the session without either sending anything or stop the smtp session without completing it.



      So it may come for the other smtp server and you can't do anything about it !
