SPF Query Tool (spfqtool) -------------------------------------------------------------------------------- The query tool is enabled and compiled by default. If you do not wish for this to be the case please return to the root of this package (cd ../../) and re-run configure like so: ./configure --disable-debug --disable-debug-logfile --enable-paranoid-malloc Of course feeling free to append or prepend any other compilation flags you may wish. If you do enable debugging, add '-d 6' in with your queries and: tail -f /var/log/spf.log. This is where you will find all debugging output instead of to stderr or stdout. Please ensure that whomever you are running 'spfqtool' as has appropriate writing permissions to /var/log. Mode 0644 would be generally appropriate depending on how anal retentive your system permissions are.
