[Exim] Exim w/ IPv6 on FreeBSD?

Hi folks,

We have FreeBSD 4.0-RELEASE approaching and I need to update the Exim
port from 3.12 to 3.13. I've had a few requests for feature changes and
wondered whether I should try turning on IPv6 support.

I'm not in a position to test this out. Has anyone had any experiences
with Exim (any version) and IPv6 on any FreeBSD 4.0-CURRENT snapshot in
the last few months?

Ciao,
Sheldon.
