[BALUG-Admin] balug.org's IP and domain are on some blocklists

RBL claims in the bounce notices below motivated me to check the BALUG
IP (96.86.170.229) and domain on DNSBLs.  There are some reputation
problems for the IP address...

$ dig -t a +short 229.170.86.96.dnsbl-1.uceprotect.net
127.0.0.2
$ dig -t a +short 229.170.86.96.all.s5h.net
127.0.0.2
$ dig -t a +short 229.170.86.96.b.barracudacentral.org
127.0.0.2
$ dig -t a +short 229.170.86.96.bb.barracudacentral.org
127.0.0.2
$ dig -t a +short 229.170.86.96.black.dnsbl.brukalai.lt
127.0.0.2
$

...and for the domain:

$ dig -t a +short balug.org.postmaster.rfc-clueless.org
127.0.0.3
$

The domain claim is definitely bogus, and I don't know why the RBL
claims balug.org doesn't accept mail to postmaster -- as I just verified
that it does:

$ telnet balug.org smtp
Trying 96.86.170.229...

Subject: Just testing postmaster deliverability

postmaster.rfc-clueless.org lists the balug.org domain, so I'm just
doing a test.  Am guessing the RBL's claim is bogus.

It could be that rfc-clueless.org's testing is aggressive enough 
to occasionally cause Exim to reject the test mails to postmaster, 
or that their text seems spammy to the rulesets, or something like
that.  I cannot remember exactly where EximConfig's whitelisting
is, but, if logfile analysis reveals where rfc-clueless.org's test
mails originate, that would be a preventative.

The other listings are more troubling, claiming that balug.org's IP
has been functioning as a spamhaus.


The bounce message (below) talks about the IP address also being listed
at 'spamrl.com', but according to
https://www.gmass.co/blog/domain-blacklists-comprehensive-guide/ ,
'SpamRL.com is a domain blacklist cloaked in secrecy' with no Web-based
or other query tools, though one can manually de-list one's IP for up 
to seven days at their Web site.
