How do you figure that? Looks like AOL is rejecting the message
because it's having DNS problems.

A third alternative to the too-big-DNS-reply problem is to run
dnscache. It strips a lot of fluff when it returns the cached info, so
too-big replies often become not-too-big. But I believe AOL has
changed their ways and no longer sends too-big replies.
