Multiple subdomains of gv.at cannot be resolved

DNS problem is solved. Domains can be resolved again. As a lot of domains were affected, it may take a while until all senderservers processed their waiting queues

The issue has been escalated to the responsible persons for DNS operation of gv.at

It seems that the zone gv.at broke their DNSSec protection, therefore subdomains of that zone cannot be resolved in DNS. Our systems do not accept mail to/from domains that cannot be resolved in DNS. Therefore our systems temporary reject such mails, so the senderservers need to re-try again after DNSSec is fixed.

There is nothing that SEPPmail can do, this must be fixed by the operators of gv.at DNS zone.
