# spamassassin no longer distributes logcheck files for spamd.
# Luckily, the logcheck-database package which distributes these files
# now doesn't reuse the same file names. This script now deletes old
# (unchanged) versions of the file, but leaves and warns about changed
# versions.
# Remove a no-longer used conffile
