Attachment handling does not work with ZIP within a ZIP

Hello,

it seems scammers are sending mails with ZIP files containing a ZIP file with a SCR file in order to pass through simpler content filters.

Even with the "Check for restricted files within ZIP attachments" enabled in MDaemon, these attachments are passed through the filter.

One would suppose that the option would work in a way that would recursively check all ZIP files it would encounter, not just the first one.

Am I missing something or is this a thing that should be fixed, since lately a larger number of those harmful mails are being passed through...

Thanks

Hello,

We currently have a feature request that our developers are reviewing that will allow MDaemon to search within compressed nested files for restricted attachments. Unfortunately, it's not yet available in the current version of MDaemon. I've updated the feature request to include your support for its development in a future version of MDaemon.

Thanks,
