This is probably the same as sendmail 8.9.0 is doing. It bounced all
mail from NetBSD.ORG for the same reason (but based on the envelope
sender). The cause turned out to be the HasWildcardMX option in
sendmail.cf. I changed
O ResolverOptions=-DNSRCH -DEFNAMES
This does not really do exactly what I want, but it works for now.
I sent a bug report to the address at sendmail.org that the
HasWildcardMX is apparently being used where it shouldn't.
