    Default [SOLVED] Law Enforcement (aka intercept)?

    The release notes for version 5.0.4 contains the following bullet:
    Law Enforcement (aka lawful/legal intercept) can be configured. User
    messages can be intercepted and sent to another mailbox. Once intercept
    is turned on, any time that the user sends a message, receives a message,
    or saves a draft, an intercept message is sent to the specified mailbox with
    the original message attached. (Bug 17539)
    Is there any additional information on this new feature? Is it available only in the NE version?
    There is nothing else in the release notes about it. I couldn't find anything in the latest Admin Guide on it. I tried looking up bug 17539 in Bugzilla, but it said I didn't have access to this bug. A search on the forums for the terms "law enforcement" and "intercept" didn't turn up any meaningful hits. Finally, I looked around the Admin console but didn't find anywhere that I could configure this setting.

    Directions in: Bug 26476 - Legal intercept feature is not documented (EDIT: I just made Legal Intercept - Zimbra :: Wiki & it should be in the official guides later on.)

    There's some additional (but easy) manual configuration needed until we fix Bug 26471 - intercept throws NPE

    Also the under construction: Bug 21761 - Legal intercept support: IM (real-time vs periodic method of save in chats folder etc)

    Original work completed via: Bug 17539 - Law Enforcement: wiretap (a.k.a. lawful/legal intercept)

    Thanks for this feature. I can understand it's intended usage for corporations and different business situations.

    However, I am using it to help my brother keep an eye on his son's first email address. My nephew is fairly young, and is fully aware any message he sends or receives will be copied to his father. This helps give the parents peace of mind and allows the the boy to email his family/friends in a situation that my sister-in-law was otherwise strongly against.

    Cool - it has all sorts of uses.

    This feature isn't as intended for abuse but they might also like the ability: http://www.zimbra.com/forums/users/1...html#post67320 (the pic in the post will explain it to you easily)

    And I'm sure they'd be advocates/want to vote for Bug 26851 - Family Mailboxes: Parental screening (Though there's other programs out there to do this at an MTA level as well.)

    Another way which is less elegant is sender_bcc_maps & recipient_bcc_maps:
    http://www.zimbra.com/forums/adminis...html#post58005
    http://www.zimbra.com/forums/install...-accounts.html
    -Doesn't help with chats like legal intercept eventually will.
    -A bounce can give it away, whereas legal intercept uses a new message envelope.

    ---Rundown of options---

    Forwards can bounce and reveal themselves if the account being forwarded to is unavailable/down/closed (maintenance mode queue's mail at MTA, while locked/lockout still deliver mail)

    recipient_bcc_maps & sender_bcc_maps & recipient_bcc_maps > per user out & in
    http://www.zimbra.com/forums/adminis...html#post58005

    legal intercept > per user (can be used to catch 'drafts', but SMTP sends are not included, it's intended for web-client, will eventually be extended to chats) http://www.zimbra.com/forums/adminis...intercept.html
