Ok. I was under the impression that 4.10 would have bigger changes
(bigger than 4.06 at any rater).

Yep.

What I would find ideal is if you included a basic dlopen
implementation (such as that patch has) in the standard release. Then
the prepackaged versions (.deb, .rpm, whatever else) would have the
dynamic loading functionality already built-in and each user wouldn't
need to patch and build their own version. It would make your exim
release self-contained and extensible from the outside.
Then the multiple functions and every other implementation would be
distributed separately. Having the basic dlopen implemenation in the
standard exim release makes distribution of the extended local_scans
easier since all they would require is dropping a .so in place and
pointing a config option at it.
That would be much more convenient (once 4.x, with the dlopen, is in
debian ...) for managing upgrades.

As you can see, though, I (well, David really) have already written
the local_scan that does all the dlopen stuff. All that remains is
copying it to your source tree :-).
