echo 1 > /var/qmail/control/dns_ip6_lookup
[[email protected] home]# cat /var/qmail/control/dns_ip6_lookup 1 [[email protected] home]#Then, create a file called /var/qmail/control/senderip6, with contents following this format: domain: ip6 address. Example:
[[email protected] home]# cat /var/qmail/control/senderip6 iwtest.net:2001:db8:0:1:1:1:1:1 [[email protected] home]#
