[IANAL] The MySQL client libraries may also be linked with software available under various other open-source licenses: http://www.mysql.com/about/legal/licensing/foss-exception/ Among these is the Common Public License, which IBM now uses instead of IPL, but it is not obvious to me that the CPL applies to Postfix. http://www.ibm.com/developerworks/library/os-cplfaq.html 1. What is the relationship between the IBM(R) Public License (IPL) and the Common Public License (CPL)? The IPL was IBM's first open source license. The CPL is essentially the next version of the IPL. the Postfix license states: IBM may publish new versions (including revisions) of this Agreement from time to time. Each new version of the Agreement will be given a distinguishing version number. The Program (including Contributions) may always be distributed subject to the version of the Agreement under which it was received. In addition, after a new version of the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the new version. so it is perhaps useful to understand whether the CPL is such a new version, and whether Postfix may now be distributed under the CPL. > I see that postfix on RHEL6 clearly links against mysql: While the IPL is listed at: http://www.opensource.org/licenses/alphabetical The MySQL FOSS exception, however, does not broadly include all OSI licenses. -- Viktor.
