Library dnsbl

A minimalistic DNS BlackList library implemented to facilitate querying various DNSBL services. The current list of services has been implemented based on the following compilations of services:

• http://en.wikipedia.org/wiki/Comparison_of_DNS_blacklists
• http://www.robtex.com
• http://www.sdsc.edu/~jeff/spam/cbc.html

The library implements a helper class through which script may access the BL services. A typical script implementation could look like this:

local helper = dnsbl.Helper:new("SPAM", "short")
helper:setFilter('dnsbl.inps.de')
local status, result = helper:checkBL(host.ip)
... formatting code ...
