and the ever failthful bc :)

err... one of 4 MX's for home email... (I'll catch the others later on)

v6 inbound: $ egrep '\[2...:' /tmp/today.from |wc -l
                    244
v4 inbound: $ egrep -v '\[2...:' /tmp/today.from |wc -l
                    135591

percent v4:
135591/(244+135591) * 100
99.82

v6 outbound: $ egrep '\[2...:' /tmp/today.to |wc -l
                      198
v4 outbound: $ egrep -v '\[2...:' /tmp/today.to |wc -l
                      196

a note about the OUT numbers... I was apparently
bouncing/connection-refusing to a relay over v6 :( so.... 2 REAL
connections out, 196 failures, w00t! (this mailserver does little
'out' email apparently)
