  • Spam filtering

    Can someone direct me to a good online tutorial about how to control spam filtering with Exchange 2010?


    Specifically, up until a few months ago, our Exchange server was doing just fine with its spam filtering. But recently (I suspect some updates doing this), we're getting ALOT of "false positives". By that I mean that messages are being redirected to the Spam folder that shouldn't be.

    --> this includes messages that are 100% internal to the exchange server (ie. an email from 1 internal user to another internal user).

    What's even weirder is that if I move a message from my Junk folder to my normal Inbox (Outlook 2010), it almost immediately gets moved back to the Junk folder.

    How are you moving the emails from junk to inbox? Are you selecting not junk, or just drag and dropping? If the latter, then the heuristic detection system hasn't been changed and it'll still flag those emails.

    Personally I'd look at a Barracuda spam appliance.

      I don't think you understood my question.

      ---> WHERE are those heuristics set and/or configured?


      I couldn't find ANYTHING in the EMC that had to do with spam filtering, the heuristics, threshholds, etc.

      Again - this has nothing to do with my question. I want to know where this is configured in Exchange. I'm not going to go buy another product.

          Re: Spam filtering

          One thing is becoming obvious - everything that talks about spam filtering in Exchange talks about using an Edge Transport server.

          I have a single Exchange server. It does not have the Edge Transport role.


          Yet email still seems like it is getting filtered....

            Do you have anything like in the attached picture?
            I had to do the below commands to get it to show on my server.

            Run the Install-AntispamAgents.ps1 script

              To confirm what UK_Network said -- spam filtering can be installed on the Hub Transport role by running the script he mentions -- it does not come out of the box.

              IMHO though, you will be better subscribing to a spam filtering service such as MessageLabs.

                Nope - that tab is not listed.



                Just to be clear - I am NOT looking to add spam filtering to my Exchange server. My problem is that there is spam filtering already going on, and it is generating false positives. I am trying to figure out what is doing it (and how to configure it).
