    Guess this should've gone in the admin section though...
    What would you use this for? To kill unwanted user's or idle user's?

    This is the second time I've done a 1995 aol/usenet "Me Too!"
    except again, I failed to use all caps.

    That said, Like some others here, I too run a moderatly complicated email
    store, I'm using courier-imap, but the same caveats apply. I have hundreds
    of gigs of maildir, deep nested folders, all in a virtual chrooted environment.
    My users gave up pop a few years back, essentially after I up and refused
    to support it any longer. I took a lot of care building my mailstore to be
    quite robust and fault tolerant.

    It would really be nice if I could use Zimbra to access this mailstore, rather
    than have to migrate out of this, well, trusted enviroment. I can't speak for
    the engineering of it, I just did the best I knew how, and worked really hard
    on it. I have a lot of faith in it. Don't want to, or rather, will not give it up.
    I hope it will last me at least another 2.5 years. I automate a lot of spamhandling
    (the same, amavis-new, spassassin, clamav, blah blah) and other things with
    courier-maildrop, again, in a chroot environment.

    I'm good on my imap mailstore, I'm quite impressed with zimbra as the
    "holy grail" of email/calendar apps, would be nice if were able to function
    as an imap client.

    As much as I really like the overall approach, and I really do, I'm very leery
    of the Java "for our principal server-side implementation language". Very
    leery. Very very leery. Java, since I've been exposed to it, and I've
    been exposed to throughout it's entire vile history, is definitly a weak
    point. It's possible to make java behave and work and play well with
    others, it's also possible to (insert $pig-flying-anecdote). There are
    reasons individual corporations work with "more than 10,000 CPUs of
    production server-side java" and not all of them are good. But like
    M$ Exchange, Java is a fact of modern life. Kinda like eventual cancer,
    and that wouldn't stop me from implementing.

    But back to the main point. I think with some additional creativity,
    (and this is nothing if not brilliantly creative) Using Zimbra as an imap
    client could maybe be doable. Would really be nice. There are some
    really good imap servers out there. I and others really like and trust
    courier-imap, the Cyrus folks are very dedicated to their excellent
    imap server, for very good reason. Okay, I'm just rambling now.

    Also, It would be nice to view/kill current user sessions from the admin interface.
    I agree. I feel that *all* servers should be able to view/kill current client sessions
    as administrator, always. I can think of many reasons why this is a good idea,
    but those could be engineered around. It's those reasons we don't think of
    that get ya.

    just to mess with fools . j/k, but seriously though -

    I'm not saying that this will be an issue for Zimbra ...but in every other group software suite I've worked with (well actually, pretty much any multi-user software period), user sessions occasionally get hung, corrupted, duplicated, obfuscated, disconnected, stale, slow, so on and so fourth. This is not necessarily due to bugs or design flaws in the application itself, but often just caused by /usr's doing unbelievably stupid things, or bugs in the underlying software/OS that the application is dependant upon. Now I really hope this won't be an issue for Zimbra, but I'm betting this will come up again. It would be better to have the functionality and not need it, than the other way around.

    Also, as CPM stated: "*all* servers should be able to view/kill current client sessions as administrator".

    I couldn't have said it better. That's one of the best things about being an admin.

    Thanks Guys,
    Keep up the Good Work!

    Well I'm still not convinced. You'd first have to identify a bad user. So assuming you do that just mark the account as inactive and they are shut off. This handles most of the use cases you describe. If anyone out there finds a way to get the server hung up like this then we'd like to know about it.

    I did. Just as apache or tomcat do not need/have a kill user function we feel Zimbra is the same. Take a look at our server design/arch and you'll see it's not the type of system where user's "get hung".

    Well, Okay then.

    The overall utility of this software is just too good.

    I guess I'm just going to have to put my prejudices aside and
    go for a good prototype roll out and see how it shapes up.

    Thanks for all of your hard work.
