But it is, and has been for a long time.

Tom did the Exim work, sky@ and krion@, the FreeBSD port maintainers picked up
the dependencies and put them into place:

Under /usr/ports/mail/libdkim

even my now-obsolete FreeBSD 7.1 has libdkim-1.0.17-tk.tar.gz

and it is found and used under /usr/ports/mail/exim

with a simple:

make -DWITH_DKIM=yes

.. producing the expected output:

/usr/ports/mail/exim/work/exim-4.69/build-FreeBSD/dkim-exim.o

etc.

Present-day FreeBSD 7.2 production release and ports does list the newer
libdkim-1.0.17_1

Both call the requisite openssl version (discussed in April-May 2008 thread).

There is still a domainkeys lib in ports for that also - same maintainer,
sky@???

I haven't checked NetBSD, OpenBSD, DragonFlyBSD, but 'pkgsrc' may well have the
DKIM option also.

Long story short:

- Yes, docs could/should be updated to better reflect the current state, above.

- But if FreeBSD rolled it all into ports NLT 7.1-RELEASE, (over a year ago),
there must be at least ONE of the many Linux distros if not *several*, that
has/have done so already. Linux is usually quicker off the mark on new stuff
than the more conservative *BSD's.

- In any case, given that the 'official' release is an OS-agnostic / fits all
POSIX-critters *source* tarball, I don't see distro-specific binaries *or*
third-party dependencies as entirely an Exim-devel responsibility.

YMMV,
