Ok, next try: I do not have IPv6 in my kernel, and the scache problems
seem to only happen for destinations that do have a IPv6 entry in their
name server. For example it does not happen for my local mail server,
but it does happen with mail.netbsd.org.

Do you have v6 in your kernel? Could dig around a bit for the relay hosts
around your messages and see if "host" reports IPv6 addresses for them?
