Blacklisted on bl.spamcannibal.org? Yet another DNSBL blacklist is gone.

Yesterday all of a sudden I got many blacklist alerts for all my servers with a public IP address:

***** Service Monitoring on icinga2 *****
Info:    CHECK_RBL WARNING - 212.103.71.210 BLACKLISTED on 1 server of 95 (bl.spamcannibal.org)

It's very unlikely that all servers are blacklisted at the same time. And as it already happened in the past (see Disable AHBL (Abuse Hosts) DNS blacklist in Spamassassin), a disabled DNSBL probably the cause.

And indeed, checking the whois of the domain reveals that the domain has expired on May 30 2019:

$ whois spamcannibal.org
Domain Name: SPAMCANNIBAL.ORG
Registry Domain ID: D98199203-LROR
Registrar WHOIS Server: whois.tucows.com
Registrar URL: http://www.tucows.com
Updated Date: 2019-05-30T02:52:25Z
Creation Date: 2003-05-26T19:20:39Z
Registry Expiry Date: 2020-05-26T19:20:39Z
Registrar Registration Expiration Date:
Registrar: Tucows Inc.
Registrar IANA ID: 69
[...]

In a browser, the appearing website is self explanatory as well:

As I'm using the check_rbl monitoring plugin, the blacklist can simply be removed or commented in the ini file containing all the blacklists.

# grep spamcannibal /usr/lib/nagios/plugins/rbl.ini
server=bl.spamcannibal.org
# sed -i "/spamcannibal/s/server/#server/" /usr/lib/nagios/plugins/rbl.ini
# grep spamcannibal /usr/lib/nagios/plugins/rbl.ini
#server=bl.spamcannibal.org

The plugin now returns OK again.
