If you overwrote the Zlib files from CPAN in F24, and the package was
not upgraded from F24 to F25, their files are not touched, so you
ended with a broken system.
In general, it's a bad idea to overwrite distribution provided files
with you own, and for amavisd-new all the dependencies are provided in
Fedora.

Kind regards.
