This sounds interesting, but it cannot be done in any variant of amavis
(to bring the discussion back to the $subject :-) that uses Archive::Zip,
as Archive-Zip doesn't support encryption.
Are any perl coders here who would be willing to add encryption support
to Archive-Zip? The maintainer told me he doesn't even use perl anymore,
which kind of bodes badly for the future of the module ...

True, I think in all versions of amavis, the default is to let files through
if amavis cannot deal with them (and the subsequent virus check finds nothing).
For amavis 0.3.x and amavisd, I have a patch that unconditionally
quarantines emails which contain encrypted .zip files.
