I'm the one who has working IPv6 connectivity, it's other hosts I'm
worried about. 8-/
Note that the failing domains I've seen so far have an MX record
pointing to an A/AAAA combination, and it seems that Exim somehow
applies the AAAA retry hint to the A host, possibly if the A host is
temporarily unreachable as well.
