installing two new libraries (and two lint thingys, but no shared or
pic stuff) and two headers files (into /usr/include/milter).
Shared libraries (etc) could be built, but as I'm currently unsure of
the ABI/API stability, I'm going to examine it more closely before
enabling it, as opposed to finding out later that it's volatile and
disabling it.
NOTE! We really ought to have a generic rc.d script to start the
milters (before sendmail or any other MTA that you have that uses
them), but I haven't finished it yet. The milter support here is
being enabled to satisfy current popular demand. I'll come up with a
script soon. Unless someone feels like beating me to it. So until
then, you're on your own.
