    Default VNC History - "No data found"

    Testing zimbra for potential production use at my institution. Zimbra Version:
    8.0.6_GA_5922.FOSS

    Installed the VNC History zimlet:

    Name: biz_vnc_lightweight_history
    Description: Displays history of email transmissions (1.0.3)

    From: http://packages.vnc.biz/zmpkg/bootst...1.4.2.0.tar.gz

    As far as I can tell it's installed. The web client shows 'Mail History' in the zimlets list in the left pane and dragging a sent mail item onto it opens a Mail History window. Problem is the window always says "No data found".

    There are no records being added to the 'mail_history_mbox' table in the zimbra mysql database and I am not sure where to look for any error logs for this zimlet.

    I am not exactly sure how this zimlet is supposed to work and the developers home page is, to be nice, lacking.

    Anybody have any experience with this zimlet or any troubleshooting tips?

    **UPDATE 1**
    Was poking around and found an error getting logged in the /opt/zimbra/log/zmmailboxd.out file. This error occurs every time an email message is SENT:

    INFO [biz_vnc_lightweight_history] Read mailbox.log file
    ERROR [biz_vnc_lightweight_history] Error while getting Internal Mail Event from Log file java.lang.ArrayIndexOutOfBoundsException: 2
    java.lang.ArrayIndexOutOfBoundsException: 2
    at biz.vnc.zimbra.lighthistoryzimlet.RecipientInterna lMailHistoryLogging.getInternalMailEvents(MailHist oryLogging.java:206)
    at biz.vnc.zimbra.lighthistoryzimlet.RecipientInterna lMailHistoryLogging.run(MailHistoryLogging.java:16 9)
    at java.lang.Thread.run(Thread.java:744)

    Anyway, I am giving up on this zimlet as it doesn't look very well supported or written.

    Knowing the exact version would be helpful.
    As zimbra user, call: zmpkg list

    Actually, it's more a toy project, to try whether the problem can be solved just by having
    a zimlet that parses postfix logfiles - instead of a larger infrastructure of milters,
    mailboxd extension, separate outbound mta, etc. It's not meant for production.
    (and it showed that it was a dumb idea in the first place).

    If you want a _working_ solution, you probably look the real VNC MailHistory System,
    which is proven in-production for large scale customers. Of course, it cost $$$ ;-p

    But this solution is far more than just a Zimlet, in fact it also needs an mailboxd-
    extension (for catching mailbox events), an milter and an separate outbound mta
    (otherwise forwards couldn't be properly catched). It's not entirely trivial to set up.
