# During SunOS 5.10, sendmail's m4 configuration hierarchy moved from
# /usr/lib/mail/ to /etc/mail/cf/ .  Ordinary packaging will deal with
# the bulk of the move, but since users are not only allowed but encouraged
# to create files within this hierarchy, we need to migrate any such files
# from the old to the new location.

# During an upgrade, the old SUNWsndmu will be pkgrm'd before the new
# SUNWsndmr (or u) is pkgadd'd.  The pkgrm should have cleaned out all
# the system files under /usr/lib/mail, so we need to consider that case,
# as well as the user running pkgadd at other times.
