[Dovecot] OT: DNS-Problem with Mailnglist-Server

is there a problem with the server, which is running this list, or do I
have an issue with my DNS-server?

mail:/ # host
Host not found: 3(NXDOMAIN)

which leads to postfix complaining:

May 30 13:28:39 mail postfix/smtpd[25014]: NOQUEUE: reject_warning: RCPT
from unknown[]: 450 4.7.1 Client host rejected: cannot
find your reverse hostname, [];
from=<dovecot-bounces at dovecot.org> to=<hanns at hannsmattes.de> proto=ESMTP
