  • Incoming messages being marked as SPAM

    Nothing has changed in GPO or on our Exchange Server (2003), but in the last two weeks some of our incoming messages have been marked in the subject line as: [SPAM] - Example Title in Subject Line

    I was told this is an Outlook/Exchange Server issue? Is this true? If so, how do I get rid of it.

    Any help is greatly appreciated.

    Nothing in Exchange that can do that. It has to be a third party application. Does your email come in directly or through a third party - such as your ISP? It could be them that is flagging the messages.

      What about in Outlook or Group Policy? Our e-mail comes in directly.

      It doesn't happen for all e-mail messages, but it is stamping about 5-15% of all incoming messages.


      Here's an example of one:

        Errmm... hate to tell you this, but that example IS SPAM.

        That looks like it could be Symantec or some other Anti-Malware product doing it...?

          It wasn't marked as spam before two weeks ago. We're using Symantec Endpoint on all the client machines. Is there something in it that would be doing this? The only Anti-Malware product I have installed on our machines is the Symantec Endpoint client and Windows Defender.

            There is no Microsoft product that flags in that way. Not Outlook and certainly not Group Policy. GP has nothing to do with antispam filtering. Therefore it is something outside of Exchange.

            The subject line of that message has also been modified - if you look at the end it says "found words do not reply in html body". If you have a Symantec product then you need to look at configuration to see if it is filtering the message.

              Looks like we're using a spam filter and its been in place for the last six months.

              This is the service: spamstopshere.com

              Is anyone familiar with them? I can't seem to find anything in the settings that would indicate they are changing the subject lines for certain incoming messages and adding the "[SPAM]" prefix.

              Not everyone is using the new Symantec Endpoint client so that can't be the cause.

              I'm stumped.

                Never heard of them.
                However if you are using a filtering service then that is the prime candidate for the cause of those additional entries in the subject line. A phone is required if you cannot see anything in the settings. Many antispam outfits are just reselling another service, so it could be a change at the service they are using.

                    Sembee - Thanks, I'm going to call them now.

                    muneer_bom3 - No, we don't have Groupshield installed on the Exchange Server. I try not to install anything on it.

                    Thanks for all the help, guys. I appreciate it and I'll update this thread once it gets resolved.
