I wish I had isolated the specific thing that I did to address the problem.

andrew.cmu.edu houses several 100+ recipient mailing lists.  The problem
in sendmail was that it would be called on to deliver mail to a whole
long list; some deliveries would be successful, some not, but it
wouldn't finish processing the entire list before it crashed or the
machine was rebooted.  Meanwhile, the qf* file hadn't been updated to
remove the destination addresses for those deliveries that had been
successful.

What I did was to insist that sendmail update the qf* file after every
successful delivery, and sync() the disk.  There were only a couple of
changes involved.  Is there a substantial call for diffs (which might
not be that useful since our local sendmail had diverged long ago)?  Or
is this diagnosis/treatment report sufficient?  Or has the problem been
solved in later versions of sendmail?
