No, it's only the A6 records that are likely to go away. AAAA records
are still going to exist, and if the name server you query times out on
AAAA records (as appears to have happened in your test), you will still
get this result. Basically, the name server is broken. It should be
saying "no such record".

I suppose I could consider adding some option for working round this
brokenness, such as "don't look up AAAA records for these domains".
Noted for Exim 4.
