seems to be an interesting link if you need to use RBL+ with Postfix, but still wants to have the Per-user-UCE ability.
This patch is also used:

Don't install a OpenSSL 0.9.6c on top of an old OpenSSL 0.9.5a, because then cipher.c in the OpenSSH 3.1p1 distribution doesn't compile. At least not on my Irix 6 machine.
Make sure you compile the OpenSSL 0.9.6c with cc (not gcc, at least not an old gcc), otherwise it's not possible to compile OpenSSH 3.1p1 with cc (some error message about not finding __eprintf).
Also, the behaviour of OpenSSL seems to have changed - It no longer uses it's own directory with lib/include/bin directories beneath, but instead puts them (the directories) directly under the --prefix directory.
Building Jython with ant was a lot easier if you had the optional tasks for Ant installed...
Errors like:

from your Python interpreter can be because of stale modulepaths, perhaps left by another installation of the same version of Python.
And as you might understand, this was learned the hard way :-).
