Hi,

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

mail:/ # host 193.210.130.67
Host 67.130.210.193.in-addr.arpa. not found: 3(NXDOMAIN)

which leads to postfix complaining:

May 30 13:28:39 mail postfix/smtpd[25014]: NOQUEUE: reject_warning: RCPT
from unknown[193.210.130.67]: 450 4.7.1 Client host rejected: cannot
find your reverse hostname, [193.210.130.67];
from=<dovecot-bounces at dovecot.org> to=<hanns at hannsmattes.de> proto=ESMTP
helo=<dovecot.org>


Regards Hanns
