Hello Patrick
I had the same issue, you have to raise log level, then you can check if zip
file is unzipped; js are blocked, but ziped files should be opened
 I solved by installing p7zip
this is not enough, you should configure amavis to use it whan you receive zip
I used this

  ['zip',  \&Amavis::Unpackers::do_7zip, ['7z','7za'] ],

I am not  an expert at all, I am very lame and I can't say this is the
proper solution, what I note was that after this configuration zipped
attachments were correctly opened
