Postfix snapshot 20140530 now supports dynamically-loadable database plugins, and Postfix shared libraries.
Dynamically-loadable database plugins are useful for people who create or install pre-compiled Postfix packages. Postfix shared libraries reduce the size of Postfix executable files. Thanks to Lamont for the initial implementation, and Viktor for the port to "current" Postfix. I added support for a directory dynamicmaps.cf.d to support per-plugin configurations files, just like postfix-files.d. The Postfix build/installation procedure has changed a bit, but there should be enough time to adopt this before the next stable Postfix release early 2015. Please see the RELEASE_NOTES. Wietse
