Thanks! This is really helpful.

Well, before I try the above commands...

Generally it is only procmail that needs access, however, I have this file
"rotated" by logrotate (run as root) on a monthly basis. It is rotated with
the "date" extension and that file is archived by a cron job (root) to DVD.

Oh, and I have a daily backup routine that uses "tar" run from a cron job that
also includes this directory...

Will those things invalidate your suggested solution?

Thanks again for you help so far. Much Appreciated...
