I remember that Mark Martinec mentioned a license change in Berkeley DB version 6 to the Affero GPL that forces Amavis to switch to LMDB. The additional provision requires that the complete source code be made available to any network user of the AGPL-licensed work https://en.wikipedia.org/wiki/Berkeley_DB#Licensing
Actually it was Wietse who said that, referring to postfix. Regarding Amavis I said that the main reason for switching BerkeleyDB to ZMQ message passing was lock contention and a slowdown of a database after long use, requiring maintenance. The license change was just an additional incentive for the change. I may look at LMDB in the future, but the current needs of Amavis are well served by ZMQ, and Redis (or SQL). The LMDB would probably be more suitable for use by SpamAssassin. Mark
