System requirements

For system requirements for PureMessage for Microsoft Exchange, go to http://www.sophos.com/en-us/support/knowledgebase/118640.aspx.

Fixed issues

  • (DEF71696) The Sophos PureMessage service fails to start if, in the spam digest configuration, the user deselects all the days on which to send quarantined spam digests.

Known issues

  • If you install PureMessage for Microsoft Exchange on a computer in a workgroup, you cannot use a Microsoft SQL Server database located on a different computer (that is, a remote database). You can specify a remote database during installation, but PureMessage for Microsoft Exchange does not set the necessary access rights. In this case, contact Sophos technical support for a workaround.
  • The installer may fail with an error Setup was unable to create the PureMessage for Microsoft Exchange databases.
    This can happen if, in the past, you have uninstalled the SOPHOS database instance from Microsoft SQL Server or uninstalled Microsoft SQL Server itself. In this case, delete the following files from the MS_SQL_INSTALL_FOLDER\MSSQL.X\MSSQL\Data folder.
    • SavexCnfg.mdf
    • SavexCnfg_log.ldf
    • SavexDir.mdf
    • SavexDir_log.ldf
    • SavexQuar.mdf
    • SavexQuar_log.ldf
    • SavexRprt.mdf
    • SavexRprt_log.ldf
  • (DEF 83210) The installer may fail with the following error:
    0x80040e14 - idispatch error 3092 unable to start the PureMessage database

    This can happen if you try to install PureMessage to a SQL instance which was installed to be case sensitive. To avoid this, install PureMessage to a SQL instance that is not case sensitive .

  • (WKI 50085) After the installation of PureMessage for Microsoft Exchange, you may receive a message "Could not connect to master synchronization server" while opening the PureMessage for Microsoft Exchange administration console. You receive this message if some of the servers in a configuration have been upgraded and others are not. To avoid this, ensure you upgrade all the servers in the configuration group one after another.
  • (WKI 51471) When attempting to install PureMessage for Microsoft Exchange, the installation may fail with a message similar to:

    Error code 1 was returned while running:<path>\Bootstrap.exe install sav <path>

    You receive this message if the installer path has exceeded the maximum character length of 256, or if you are installing from a network location. To avoid this, copy the installer locally with install path not exceeding 256 characters.

  • Tags added to email subject lines (if you set up Email tagging) may be displayed as question marks.

    This occurs when all the following conditions apply:

    • The subject tag contains extended characters, such as Japanese text.
    • The message is encoded in TNEF, which requires that it is sent from a MAPI mail client.
    • The message is encoded using a character set that doesn't support characters specified in the subject tag.
    • The message is viewed with a mail client that uses the multi-byte subject property rather than the wide-character subject property.
  • (WKI 57286) Non-ASCII characters in Disclaimer text may be displayed as question marks when added to the TNEF messages sent in plain-text format. This issue occurs when the original message Charset does not support the non-ASCII characters.

    To avoid this, it is recommended to use standard ASCII characters when defining disclaimers in PureMessage.

  • (WKI 55150) If you install PureMessage for Microsoft Exchange on a computer that has Sophos Enterprise Console installed, Sophos Enterprise Console will display a "Differs from policy" error. The error is displayed as PureMessage for Microsoft Exchange will set the autoupdate frequency to 5 minutes from Sophos Enterprise Console's default update policy of 10 minutes.

    To Workaround this problem, reapply the default update policy for PureMessage for Microsoft Exchange systems, or create a seperate group and add allPureMessage for Microsoft Exchange servers to that group with a new updating policy.

Additional information

  • The installation program will restart IIS and Microsoft Exchange services (if present) during the installation. Under certain circumstances it may also require the computer to be restarted.
  • PureMessage for Microsoft Exchange spam rules are updated every five minutes from Sophos with small update packages. It is recommended that this updating frequency is not changed, for optimal spam capture rate and optimal bandwidth utilization.
  • When you install PureMessage for Microsoft Exchange, Sophos Anti-Virus is also installed (if not already present) and on-access virus scanning starts automatically. However, PureMessage for Microsoft Exchange excludes certain Microsoft Exchange and IIS folders from virus scanning as recommended by Microsoft. When PureMessage for Microsoft Exchange is uninstalled these exclusions are not removed. For more information about the folders that are excluded, see knowledgebase article 35970.

    The \Temp folder under the PureMessage for Microsoft Exchange installation folder is also automatically excluded from virus scanning. However, when PureMessage for Microsoft Exchange is uninstalled this exclusion setting will be removed from Sophos Anti-Virus.

  • You cannot upgrade a version of PureMessage for Microsoft Exchange that includes both anti-virus and anti-spam support to a version that includes only anti-virus support.
  • During installation on a cluster, you may notice a few errors in the event log as described below.

    These errors are reported because the PureMessage for Microsoft Exchange cluster resource DLL is not present on all nodes during installation. After PureMessage for Microsoft Exchange is installed on all nodes, these errors will no longer be reported. These errors can be ignored safely.

    Source

    Event ID

    Description

    ClusSvc

    1058

    The Cluster Resource Monitor could not load the DLL PmClustResTypeXXXX.dll for the resource type PureMessage service X.X.X.X.

  • On Windows 2008, you may notice warnings in the event log from the Windows Defender Real-Time Protection agent as described below.

    Please choose to allow Sophos applications.

    Description:
    
    Windows Defender Real-Time Protection agent has detected changes. 
    Microsoft recommends you analyze the software that made these changes
    for potential risks. You can use information about how these programs
    operate to choose whether to allow them to run or remove them from 
    your computer. Allow changes only if you trust the program or the 
    software publisher. Windows Defender can't undo changes that you 
    allow.
    
    For more information please see the following:

    file:C:\Program Files\Sophos\PureMessage\bin\FireJob.exe;
    taskscheduler:C:\Windows\tasks\Sophos-PureMessage-StoreMonitorHealthCheckTask.job
    
    Alert Type: Unclassified software
    
  • The default action in the case of an application error is Deliver message. Sophos strongly recommends that this action is not changed.
  • PureMessage for Microsoft Exchange does not support multiple administration consoles running simultaneously on the same machine or multiple administration consoles connecting to the same server at the same time.
  • Files left behind after the uninstallation of PureMessage for Microsoft Exchange:

    The quarantine directory INSTALLDIR\Quarantine is left behind on the server. This enables you to retain quarantined items during uninstallation and reinstallation of PureMessage for Microsoft Exchange. If you no longer need the quarantined items, delete this directory.

    On an SCC cluster, the Quarantine folder can be found on the shared drive under SHAREDDRIVE\Sophos\PureMessage\Quarantine.

    The logs directory INSTALLDIR\Logs is left behind on the server. If you no longer need the log files, delete this directory.

    The file PMClustResTypeXXXX.dll is left behind in the C:\WINDOWS\system32\ folder. This is the PureMessage for Microsoft Exchange cluster resource DLL that can be deleted from all nodes in a cluster after PureMessage for Microsoft Exchange is uninstalled from all the nodes.

    On an SCC cluster, the following folders are left behind on the shared drive:

    SHAREDDRIVE\Sophos\PureMessage\Config

    SHAREDDRIVE\Sophos\PureMessage\ReportsPending

    These folders can be deleted after uninstalling PureMessage for Microsoft Exchange from all nodes.

  • An Exchange Edge Transport server has an attachment filtering agent, which filters mail at the protocol level. As a result, some viruses are removed, and some attachments replaced before PureMessage for Microsoft Exchange gets to scan the email. For this reason, the Dashboard and Activity Monitor may display a lower level of unauthorized traffic for a server providing protection at the network perimeter than for other servers.
  • After installing PureMessage for Microsoft Exchange, it is recommended that Windows Update is run on the server to ensure all the latest security patches are installed.
