Install a different version of Exim.

There is no DKIM support in Exim prior to 4.69.

Exim 4.69 has just been replaced by Exim 4.70, which changes the DKIM
implementation.

In 4.69, DKIM uses a modified third-party DKIM library which had some
issues and did not integrate too well. This DKIM support was classed as
"experimental".

For Exim 4.70, Tom Kistner wrote a new DKIM implementation. It's
native, integrates better and is no longer "experimental". It is not
compatible.

So: Exim 4.69 has a couple of years of stability but poor DKIM support.
Exim 4.70 is new, the DKIM support is very new and there may be some
stability shakedown. On the whole, Exim has a very good track record
for stability, so what issues might exist should not be too severe.

In your situation, I'd install Exim 4.70 and read the docs which come
with it, including the new chapter on DKIM setup.
