This is incoming only, mostly mailing lists (including a few *busy* ones):

:; zgrep -Ec 'client=[^[]+\[[^]]+:' /var/log/mail.info* |awk -F: '{i+=$NF} END {print i}'
33966

:; zgrep -Ec 'client=[^[]+\[[0-9]+\.' /var/log/mail.info* |awk -F: '{i+=$NF} END {print i}'
176978

so 19.19% ipv6.

That is somewhat biased by the fact that debian and, IIRC, gnome lists
are sent from ipv6-capable hosts and their bugs lists are among the
busiest lists.

For outgoing, s/client/relay/ which results in about 4.75% ipv6.
