You figure this out at all. We started getting this on a new installation with .xlsx attachments. Sender is whitelisted. Tried reinstalling clam and still getting the errors.

After some more research, we cannot get any Office 2007 and up documents through. All xlsx and docx and pptx fail. They hang in queue for about an hour and then fail with the same message you get. This is a brand new Mailscanner installation. We copied the exact configuration from our previous server into this one.

Change Maximum Archive to 0 and it will work.

It looks like it is a bug in cpan Archive::Zip version 1.30. There is a bug report on it (https://rt.cpan.org/Public/Bug/Display.html?id=61930) but no updated version. However, I manually downgraded to version 1.29 and 1.28 and could not get messages through so I'm not sure.
