You'd need to find out why it started happening in the first place. What software wrote those filenames? Are new filenames still creating with wrong S value? Does your dovecot.conf use zlib plugin globally (instead of only in some protocol sections, which might cause this kind of trouble)?

It's an ugly workaround for the wrong S=size problem when zlib is used. Preferably you wouldn't ever need to use it.
