    Default Zimbra license vs. GPL


    I have a question about Zimbra licensing, in particular I believe usage of
    MySQL Connector/J (which is under GPL) in the same address space as
    Zimbra Mailbox Daemon (which is not -- and it is not under any other
    listed open-source licenses in official MySQL download -- however Zimbra
    third party licensing states, that it is pure GPL) is to my information violation
    of GNU GPL. This concerns binaries under Zimbra Public End-user License Agreement (EULA) and binaries, which were made from sources covered by
    Yahoo Public License.

    Could someone from Zimbra please clarify this? What is the license you
    distribute MySQL Connector/J under? If it is GPL, I believe linking them
    together is not permitted by MySQL Connector/J license.

    Thank you,

    Hi Jooray,

    Thanks for your note. We have a commercial license from MySQL to redistribute MySQL Java connector with OSS edition of ZCS. Thus, we are not using it under the terms of the GPL, but rather the terms of the commercial license.

    Default License

    Yes, but I would like to know, what kind of license it is.

    Because you state here:

    that it is under GPL. Which is (as you said) not correct, but I would like to
    know, what kind of license it is -- what are my rights, responsibilities, etc.
    when I distribute Zimbra or derived works under.

    So my question remains: by which license am I bound, if I compile ZCS or distribute it myself.

    (If you are curious, we are not doing any derivate work based on ZCS right now, but we have some clients for which we install ZCS. We also would like
    to use unofficial community port of ZCS for Solaris).

    So: if we redistribute Zimbra, can we redistribute MySQL Connector/J too?
    Under what terms?

    Thank you for your answer, I'm sorry to bother you with lawyer stupidities,
    but some people consider it important.
