This came up a few days ago. The problem is that AOL is returning greater than
512 bytes for an "any" lookup, and qmail doesn't handle that. (There was a huge
flame war with Dan on the subject several months ago.)
There are a couple of solutions to the problem. One is to patch qmail to handle
these larger DNS responses. Check http://www.qmail.org for patches. The easier
solution is to avoid AOL DNS lookups altogether by making an entry in
smtproutes for AOL. Look up the MX records for aol.com manually, and put one of
the best-preference MX exchangers in control/smtproutes, like so:
aol.com:za.mx.aol.com
