Hello Patrick<br>
I had the same issue, you have to raise log level, then you can check if zip<br>
file is unzipped; js are blocked, but ziped files should be opened<br>
I solved by installing p7zip<br>
this is not enough, you should configure amavis to use it whan you receive zip<br>
attachments<br>
I used this<br>
<br>
unshift(@decoders,<br>
['zip', \&Amavis::Unpackers::do_7zip, ['7z','7za'] ],<br>
);<br>
<br>
I am not an expert at all, I am very lame and I can't say this is the<br>
proper solution, what I note was that after this configuration zipped<br>
attachments were correctly opened<br>
