Thanks for the link, Viktor. That was back in 2010; has Wietse not
fixed this since then? I'd rather lose the ability to differentiate
between different links (and lose the ability to send to link local
addresses) than not be able to say link-local hosts are part of
mynetworks. I'll note that it's unlikely that we could send to a
link-local address anyways because there's really no way to put that
into DNS, so we're not actually losing anything by that. As for the
ability to differentiate between different links, that would only be an
issue for hosts with multiple interfaces. Again, I don't consider that
a big issue.
I would suggest that Wietse go ahead with his initial suggestion and
remove the link scope so he can continue to use the existing v6 address
matching logic. While it's not 100% "correct" to do this, I think the
benefits far outweigh the drawbacks (the main drawback in my case being
rejected mail!)
Wietse?
