According to Ollivier Robert:
> Error: bind(2a01:240:fe5c:1::3, 143) failed: Can't assign requested address
> Error: service(imap-login): listen(2a01:240:fe5c:1::3, 143) failed: Can't assign requested address

Thanks to a friend of mine, using this in /etc/sysctl.conf for the host (or setting it manually if you don't want to reboot of course) fixed it:

## -- for jails
net.inet6.ip6.dad_count=0

I guess the killer things was that if the interface was too slow to come up due to the DAD protocol.  There I do not want to use DAD at all, I'm fixing all jails addresses automatically.

So now, I'm all set.
