Hi Community
Since yesterday we see more and more message of the kind:

It looks like all those cases are hosted @ metanet.
But there are some mailserver @ metanet which do accept emails.
Is there any known DNS issue with metanet? According to their status page there are no issues.
Or is something wrong with the readability of our DNS from outside AS6772?
(ns1.imp.ch, ns2.imp.ch)
