    Have a problem with Forefront for Exchange and the POP3 connector on a
    SBS 2008 server.

    The POP3 connector displays as running in services, but errors when a
    retrieve is tried manually.

    Tried adding the IP address to the approved sender domains in
    Forefront admin console, but still the same result, POP3 connector
    errors.

    To remedy problem, uninstalled Forefront, POP3 connector now runs
    normally.

    Anyone have any ideas?

  2. Hello Scottie,

    Thanks for your post.

    Generally, Forefront Server Security for Exchange should not block POP3 protocol or any related ports. However, I am wondering if there is any
    corrupted/sensitive/malicious attachment with your POP3 message that were filtered out by Forefront Server Security if you ever configured any Filtering rules on Forefront
    Server.

    If so, please check the FILTERING node and see if you have defined any file or content or domain based rules that might block the message from going through. Meanwhile,
    please check the REPORT node, then click Quarantine and Incidents tab to see if there is anything been blocked according to the records log information.

    Hope this helps. Also, if you have any questions or concerns, please do not hesitate to let me know.

    Thanks for the reply, filtering was checked along with quarantine
    incidents etc. Nothing there.

    Additionally the mail server was added to the approved senders and
    domain list - but the problem still remained.

    Curiously POP3 mail via Outlook on the client workstation worked,
    however using SBS2008 POP3 connector errored despite successfully
    running as a service.

    My suspicion is that Forefront works only with SMTP inbound via the
    Hub Transport layer, perhaps seeing the POP3 connector as perhaps an
    unauthorised transport layer and refusing connection.

    It is academic now, I've removed Forefront and using a 3rd party A/V
    solution.

  4. Hi Scottie,

    Thanks for your reply.

    By default, if you select to install the trial version of Forefront Security for Exchange, it will not conflict and does support POP3 protocol. Distributed protection on all storage
    and transport Exchange server roles, including Edge, Hub, and Mailbox/Public Folder servers. Also, based on customers and my tests, my POP3 Connector works well with
    the protection of Forefront Security, all are working fine. Here is a thread from Forefront Security for Exchange Server forum:

    Will Forefront Security work with pop connector
    http://social.technet.microsoft.com...e/thread/d4de9095-46d3-4748-8ced-ffcf2d1ea703

    Therefore, I would like you try to manually repair of Forefront Security for Exchange Server to have another try instead of uninstalling it directly.

    To manually repair Forefront Security for Exchange Server, do the following:

    1£® Reinstall Forefront Security for Exchange Server.
    2£® Apply the Microsoft Forefront Security for Exchange Server software update.
    3£® Configure Forefront Security for Exchange Server on your server that is running Windows SBS 2008. This ensures that Forefront Security for Exchange Server has the
    recommended settings for Windows SBS 2008.

    More resource:

    To enable/disable Forefront you can issue the fscutility /enable or /disable command by following the same steps cited below. This method can be safely used instead of a
    Forefront for Exchange uninstall to isolate whether the issues is Exchange related or Forefront related.

    Disabling or enabling the product by using the FSC utility
    http://technet.microsoft.com/en-us/library/dd639369.aspx


    Data collection method for troubleshooting - "FSCDiag.exe":

    This is the most used and common data collection method for troubleshooting Forefront for Exchange. This utility, when executed, will prompt the user to add a multitude of
    files including the programlog.txt, HRLog.txt, windows event logs, ForefrontInstall.log, Forefront configurations (contained in the .fdb files) and the Forefront registry settings
    (contained in the Reg_ForefrontSoftware.txt file). This utility is run from the Program Files (x86)\Microsoft Forefront Security\Exchange Server directory. The output file, in the
    naming format of "ForefrontDiag-%servername%-%date%.zip", will be deposited in Program Files (x86)\Microsoft Forefront Security\Exchange Server\Log\Diagnostics
    directory.


    Hope this helps. Also, if you have any questions or concerns, please do not hesitate to let me know.
