This program is a very basic interface to Paul Vixie's RBL filter. The basic idea of the filter is that when someone is blacklisted for an email abuse, a new domain name is resolved in the form of "a.b.c.d.rbl.maps.vix.com", where "a.b.c.d" is actually the IP address "d.c.b.a". For example, if the IP address 127.0.0.2 were listed as a blacklisted address, "2.0.0.127.rbl.maps.vix.com" would have a DNS entry (this is a real example; that address is in place as a verification mechanism). For more information about the RBL blacklist, please take a look at http://maps.vix.com/rbl/ . For more information about BIND, drop by http://www.isc.org/bind.html . Any ideas, bugfixes, or porting notes should be sent to me at "emarshal@logic.net". Don't bug the MAPS people about this; they didn't write it, and probably woudn't like getting a bunch of mail about it.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
