Sound logical. Mine was created more classical way ` zfs create tank/root/mails`

Well seems it was the other problem side effect.

Postfix and dovecot does not start because the ipv6 address was locked by the
host at jail startup time.

Change sysctl net.inet6.ip6.dad_count=0 allow those services to start correctly
AND now /var/mail is not [restrited] anymore. I think the 2 issues were linked.
