can this be reproduced with latest release from here? https://github.com/pbiering/roundcube-rcguard If not, please close this issue.

Looks like related to https://github.com/monitoring-plugins/monitoring-plugins/issues/894, while `check_dns` from Nagios plugins was extended, Monitoring plugins refer to use `check_dig` as replacement. So I see some options 1. clearly mark `check_dns` as...

During evaluation/migration it turned out that `check_dns` cannot be 100% replaced by `check_dig` - `check_dns` by default is using DNS servers configured in /etc/resolv.conf for a query and can be...

found even more curious behavior while tweaking local DNS resolution: ``` /opt/omd/versions/5.20-labs-edition/lib/monitoring-plugins/check_ping -H ipv6.bieringer.de -w 3000.0,80% -c 5000.0,100% -p 5 -6 /usr/sbin/ping -4 -n -U -w 30 -c 5 ipv6.bieringer.de...

I'm currently using this here: ``` monitoring-plugins/check_rbl-1.7.0 -H -t 60 -w 1 -c 1 -s zen.spamhaus.org -n a.gns.spamhaus.org ```

@audiocoach : with option `-n` should work, can you show debug output? Example from here ``` monitoring-plugins/check_rbl-1.7.0 -H -t 60 -w 1 -c 1 -s zen.spamhaus.org -n b.gns.spamhaus.org -d [DBG]...

please reopen if still reproducable with current version
