This is due to AOL returning too big a DNS record when you query for
their MX. There are basically two solutions to this - either apply a
patch, which you'll find on the qmail web site, or set up a static
route to the AOL MX of your choice. The latter solution is of course
subject to problems should AOL discontinue the use of the MX you've
chosen.
