========================================================================
    Known issues in this release: 

    #1  Known issue: [Reported at: DDEI 2.5.1 Service Pack 1 B1118]
    **Problem:** When only the "Connect to Smart Protection for Web
     Reputation Services" option is enabled on the "Administration >
     Scanning / Analysis > Other Settings > Smart Protection"
     screen, Deep Discovery Email Inspector does not perform
     connection tests for the following:
    
    * Web Inspection Service
    * Certified Safe Software Service
    * Community File Reputation
    
    **Solution:** On the "Administration > Scanning / Analysis >
     Other Settings > Smart Protection" screen, either clear the
     "Connect to Smart Protection for Web Reputation Services"
     checkbox or select both "Connect to Smart Protection for Web
     Reputation Services" and "Connect to global services using
     Smart Protection Server".


    #2  Known issue: [Reported at: DDEI 2.5.1 Service Pack 1 B1118]
    **Problem:** If Web Reputation Service and Community File
     Reputation are unreachable using IPv4 addresses in a dual-stack
     network, the Administration > System Maintenance > Network
     Services Diagnostics screen still displays the final resolved
     IPv4 addresses for these services.


    #3  Known issue: [Reported at: DDEI 2.5.1 Service Pack 1 B1118]
    **Problem:** When performing sandbox analysis using a Windows
     10 image that requires higher system resources, the performance
     of Deep Discovery Email Inspector may be affected.
    
    **Solution:** Trend Micro recommends evaluating the system load
     capacity on Deep Discovery Email Inspector before using a
     Windows 10 sandbox environment for analysis.


    #4  Known issue: [Reported at: DDEI 2.5.0 GM B1300]
    **Problem:** Deep Discovery Email Inspector cannot receive
     incoming emails messages from other IPv6 subnets if the "Hosts
     in the same address class" option is enabled on the
     "Administration > Mail Settings > Limits and Exceptions"
     screen.


    #5  Known issue: [Reported at: DDEI 2.5.0 GM B1300]
    **Problem:** After daylight savings time changes to standard
     time on Deep Discovery Email Inspector, a duplicate time value
     appears on widgets.


    #6  Known issue: [Reported at: DDEI 2.5.0 GM B1300]
    **Problem:** While operating in SPAN/TAP mode, Deep Discovery
     Email Inspector cannot capture VLAN traffic that is
     encapsulated by Cisco Inter-Switch Link (ISL) protocol.


    #7  Known issue: [Reported at: DDEI 2.5.0 GM B1300]
    **Problem:** Deep Discovery Email Inspector is unable to import
     Virtual Analyzer images from an FTP server in active mode. Deep
     Discovery Email Inspector security does not allow this type of
     connection.
    
    **Solution:** Trend Micro recommends using FTP servers in
     passive mode, or importing the Virtual Analyzer images through
     another method.


    #8  Known issue: [Reported at: DDEI 2.5.0 GM B1300]
    **Problem:** Deep Discovery Email Inspector cannot read the
     subject of email messages in non-standard formats.
    
    **Solution:** Trend Micro recommends only routing
     standard-formatted email messages. Most mail user agents cannot
     read email messages in non-standard formats.


    #9  Known issue: [Reported at: DDEI 2.5.0 GM B1300]
    **Problem:** Time format in the following pages cannot be
     changed if "Date and time format" in the "System Settings >
     Time" page is changed.
    1. "Last updated" time of each widget in "Dashboard > Add
       Widgets"
    2. "Last update" time in widget preview screenshot
    3. Time in email screenshot in "Detection" details.
    
    **Solution: **
    1. For "Last updated" time of each widget, it was a
       limitation of the widget framework used in Deep Discovery
       Email Inspector to show time in a corresponding format.
    2. For "Last update" time in the widget preview screenshot,
       it is not possible to be changed due to the fact that the
       preview screenshot is a picture.
    3. For the time shown in the email screenshot, it was created
       by the third-party email client. It depends on locale to show
       proper time format, not the user-defined time format.


    #10 Known issue: [Reported at: DDEI 2.5.0 GM B1300]
    **Problem:** Some risky URLs in an email may not be rewritten
     to be a link redirected to blocking or warning page, even if
     the same URLs have been rewritten, if there are more than 60
     URLs in an email.
    
    **Solution:** Deep Discovery Email Inspector will at most
     extract 60 URLs from an email for scanning by default. If some
     of the URLs were scanned have a risk, they will be rewritten to
     a link that can redirect to a blocking or warning page. If the
     number of URLs in the email exceeds 60, some of URLs will not
     be rewritten due to the fact that they were not extracted by
     Deep Discovery Email Inspector.


    #11 Known issue: [Reported at: DDEI 2.5.0 GM B1300]
    **Problem:** In Deep Discovery Email Inspector 2.5, submission
     filters were updated to allow the user to select the specific
     file type groups to be analyzed. After upgrading from Deep
     Discovery Email Inspector 2.1, the specific file type group,
     (which includes file types selected in Version 2.1) will be
     automatically selected to be analyzed. Afterward, the other
     file types which belong to the specific file type group will be
     also selected for analyzing.
    
    **Solution:** Re-configure "Submission Filters" in the
     "Administration > Scanning / Analysis > Virtual Analyzer >
     Settings" page to select the necessary file type groups.


    #12 Known issue: [Reported at: DDEI 2.5.0 GM B1300]
    **Problem:** Deep Discovery Email Inspector cannot scan
     password-protected Office PowerPoint 2003 files.
    
    **Solution:** The encryption of Office PowerPoint 2003 files is
     different from later versions, and this format cannot be
     decrypted.


    #13 Known issue: [Reported at: DDEI 2.5.0 GM B1300]
    **Problem:** If the user enables "Connect to Smart Protection
     Server for Web Reputation Services" in the "Administration >
     Scanning / Analysis > Other Settings > Smart Protection" page,
     the internal Virtual Analyzer will not run the URL block reason
     query, Census query or the Certified Safe Software Service
     query. Additionally, it will not provide Smart Feedback.
    
    **Solution:** This is the configuration of the internal Virtual
     Analyzer. The user can either disable "Connect to Smart
     Protection for Web Reputation Services" in the "Administration
     > Scanning / Analysis > Other Settings > Smart Protection" page
     or enable both "Connect to Smart Protection Server for Web
     Reputation Services" and "Connect to global services using
     Smart Protection Server" in the "Administration > Scanning /
     Analysis > Other Settings > Smart Protection" page.


    #14 Known issue: [Reported at: DDEI 2.5.0 GM B1300]
    **Problem:** When integrated with Deep Discovery Analyzer, the
     final risk level of a malicious URL in Deep Discovery Email
     Inspector is different with the risk level in Deep Discovery
     Analyzer.
    
    **Solution: **Deep Discovery Analyzer can support several
     different products with varying risk levels, so for Deep
     Discovery Email Inspector, the risk level for malicious URLs
     returned by Virtual Analyzer (no matter whether either internal
     Virtual Analyzer or Deep Discovery Analyzer) will be downgraded
     one level.


    #15 Known issue: [Reported at: DDEI 2.5.0 GM B1300]
    **Problem:** After upgrading from Deep Discovery Email
     Inspector 2.1 to 2.5, the web console cannot be redirected to
     the login page automatically. Additionally, the certificate of
     Deep Discovery Email Inspector will be changed, therefore the
     user needs to confirm and accept the new certificate.
    
    **Solution:** Re-open Deep Discovery Email Inspector web
     console and login again.


    #16 Known issue: [Reported at: DDEI 2.5.0 GM B1300]
    **Problem:** For the same email attachment which has a
     different file name, after being analyzed by Deep Discovery
     Analyzer, the analysis reports for the two attachments will
     have the same file name.
    
    **Solution:** As the current specification of Deep Discovery
     Analyzer, it will return the cached analysis result for the
     same files or URLs to Deep Discovery Email Inspector.


    #17 Known issue: [Reported at: DDEI 2.5.0 GM B1300]
    **Problem:** Under Microsoft Edge and IE10, there will be two
     delete icons at the end of "Search" box in "Dashboard > Add
     Widgets" page.
    
    **Solution:** Microsoft IE10 and Edge will create a delete icon
     for "Search" box by default. However, Widget Framework has
     already created another delete icon.


    #18 Known issue: [Reported at: DDEI 2.5.0 GM B1300]
    **Problem:** Under the current specifications of Deep Discovery
     Email Inspector, Single-Sign-On from Control Manager is not
     supported under the HTTP protocol.
    
    **Solution:** Log into the Control Manager web console using
     HTTPS protocol.


    #19 Known issue: [Reported at: DDEI 2.6.0 GM B1298]
    When Deep Discovery Email Inspector connects to a proxy server
    that supports multiple HTTP authentication methods, some
    services (except ActiveUpdate and product license registration)
    may not function properly. On the Network Services Diagnostics
    screen, the service status becomes Unsuccessful.


    #20 Known issue: [Reported at: DDEI 2.6.0 GM B1298]
    When a message contains more than one suspicious file attachment
    with the same SHA1 value, the Detections screen displays only
    one entry for the multiple file attachments.


    #21 Known issue: [Reported at: DDEI 2.6.0 GM B1298]
    If the default gateway is configured on a network interface
    other than eth0 using CLISH, the web console does not display
    the current default gateway and DNS settings.
