[Thomas Mieslinger]

Hi,

sorry for cross posting, but my message to dns-operations is still 
awaiting moderator approval. If some could reach out to c-dns.pl admins. 
Thanks.

mail to tech-pl at dns.pl unanswered, mail to dnsmaster at nask.pl bounced.

This makes my recursors and sometimes 1.1.1.1 recursors reply with 
servfail for queries.

This makes it hard for my customers to send an receive email.
