Ok, I see the problem now. Where is the problem exactly at the moment: just the mail servers, or are there also other machines/servicess which are starting to do AAAA lookups? If it is just the mailservers you could try to configure them to not try AAAA lookups, or if that is not possible modify the code. At some point when ipv6 becomes more common and/or more software starts being ipv6 aware you are going to run into this problem again even if you do fix your mailservers now, so planning to upgrade your DNS servers might be wise.
