What we have done on occassion is to add an entry for yahoo.com to
/var/qmail/control/smtproutes which redirects all yahoo.com to be
routed to a seperate qmail machine. There we can either nuke the files
periodically (via a very short queue lifetime), or increase the tcp
timeout values to help compensate for these very slow domains.
