Problem when sending email to AAAA only host:

Jun 28 20:56:43 linstar smtp[31181]: S181400AbPF1S4P: to=<test@wiget.ipv6.t17.dhs.org>, delay=00:00:28, xdelay=00:00:11, mailer=smtp, stat=error2 smtp; 500 (nameserver data inconsistency. No MX, no address: 'wiget.ipv6.t17.dhs.org')

[misiek@linstar misiek]$ host -a wiget.ipv6.t17.dhs.org
Trying null domain
rcode = 0 (Success), ancount=1
The following answer is not authoritative:
wiget.ipv6.t17.dhs.org  78013 IN        AAAA    3ffe:902:11::2
For authoritative answers, see:
[...]

so AAAA record exist for this host.

For other host where A and AAAA record exist together:
sh1.iijlab.net  122547 IN       A       202.232.15.98
sh1.iijlab.net  1871 IN AAAA    3ffe:507:0:1:260:97ff:fe07:69ea

everything is ok:
Jun 28 20:48:47 linstar smtp[30948]: S181400AbPF1SrO: to=<itojun@iijlab.net>, delay=00:01:33, xdelay=00:01:16, mailer=smtp, relay=sh1.iijlab.net ([ipv6 3ffe:507:0:1:260:97ff:fe07:69ea|25|3ffe:902:12::10|2867]), stat=ok3 250 DAA26731 Message accepted for delivery
