Thanks for any assistance with this issue. How do we configure the system to allow encrypted ZIP files that contain otherwise banned content? Is there a configuration option or combination of options within Amavis or somewhere else that we should look? Although it seems like nothing is being entered, Terminal is tracking which keys you enter. I understand why this is cool for most organizations, and we obviously want banned content to get blocked under other circumstances. txt doesn't help since the filters seem to use file to determine the type, rather than the extension. If I double ZIP the contents, with the outermost ZIP being password encrypted, we can pass the content through.
It would appear that Zimbra (via Amavis?) is doing a regex search against the contents of the zip, and blocking the content, regardless of the password encrypted ZIP file. STEP 3: Once you import your ZIP file to the PassFab for ZIP, the next step is to select the right recovery method. STEP 2: Now, you need to import your password-protected ZIP file. Once the installation process finishes, open the tool. We have disabled the blocking of encrypted archives, but that does not allow us to send anything in the banned content list via an encrypted ZIP. STEP 1: First of all, download and install the PassFab for ZIP.
Our organization needs to be able to send and receive otherwise banned content (exe,bat,dll, etc.) via a password encrypted ZIP archive. The attachment filtering works a little too well.
All seems to be well, with one big problem (for us anyway).
