Domain names with dots inside are supposed to be fully qualified, these days.

That's a feature.

As an example, you might want to send email to You mistype and
use Your local domain,, has a wildcard MX. Your email
thus, effectively, gets delivered to "" instead of being
rejected immediately.

The search feature was a mistake, thus it's off by default. You can still
use the ndots option if you really need it.

That's my understanding. Corrections are of course welcome.
