While there may or may not be a problem with sendmail's handling of
AAAA records, this is ultimately a problem with the name servers for
prodigy.net.mx. They are all running an old version of BIND, 8.1.2.
None of them are answering authoritatively for that zone. If they are
asked for a <name, type, class> tuple that isn't in the prodigy.net.mx
domain, they return SERVFAIL. This might be a bug in 8.1.2. [Who
cares? It's long dead.] Or it could be that the servers attempt to
resolve those queries, find the zone's NS records point at themselves
and then give up with a SERVFAIL.

I've Cc'ed the SOA RNAME contact for this zone so hopefully someone
there will fix the problem of the non-authoritative answers and
upgrade their name servers.
