An alternative path is renaming. What we did awhile back (in
filename.rules.conf) was to change the “deny” rule at the end to:

rename to _$1.$2        \.([a-z][a-z0-9]{2,3}\s*)\.([a-z0-9]{3})$

E.g., “feefie.foe.fum” becomes “feefie_foe.fum”. I think. It’s been
awhile. It has really cut back on the gripes from false positives.
