This directory contains files for a thunderbird extension, called 'spfdnssec', that displays the Received-SPF mail header and its various fields. In particular, it displays the 'x-dnssec' field that shows the result of DNSSEC validation during the SPF processing. To compile, just run 'make'. This will create a file named spfdnssec.xpi. This can be used to install the extension in thunderbird from the Tools->Extensions menu.
