This is clearly an aim one day. The problem is deciding when. If I had
done that when the first IPv6 code was put into Exim, it would have
failed to compile on most OS on which it ran, because the IPv6 libraries
were not present. (That was release 1.62, some time in 1997.)

That's just the DNS looking up bit. Enabling IPv6 changes a lot more
than that.
Nowadays, I think most OS do include the IPv6 libraries. But some people
still run old versions. IPv6 didn't make it into Solaris until Solaris
8. I bet there is still a lot of Solaris pre-8 around, for example.
So I'm cautious. I don't think the time is quite right yet.
