You're using the Open Root Server Network? I think 184.108.40.206 was
an ORSN root server. I say was, because it looks like ORSN is toast:
Check your dnsroots.global (probably /etc/dnsroots.global) , that's
where root/servers/@ comes from when dnscache is configured. I think
you need to get both updated, quick (check the second URL).
As to why your qmail instance is sending mail there:
[me [at] somebo]$ dig A cr.yp.to @220.127.116.11
