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.
