There are two separate problems:
- How to get dynamic loading of modules to work on multiple platforms.
- How to make optional features of Postfix dynamically loadable.
AFAIK LaMont's work solves the second problem, and the first problem for
(at least Debian) Linux. The code in the Tcl distribution is a good
starting point for solving the first problem accross a broader range of
platforms.
