Attachment Sandboxing uses advanced sandbox technology to quarantine harmful email attachments that can evade other antivirus or anti-spam software.
Attachment Sandboxing Settings
To get to Attachment Sandboxing settings:
- Click on Service Settings
- Select Sandboxing
-
Use Attachment Sandboxing default policy - If enabled, this default policy sandboxes all of the following attachment types:
- .com, .doc, .docm, .docx, .dot, .dotm, .dotx, .exe, .htm, .html, .pot, .potx, .pps, .ppsx, .ppt, .pptx, .rar, .rtf, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .zip
- .jpeg, .jpg, .pdf, .png (which are also scanned for QR codes that are converted to a URL, which is then checked for malicious behaviors)
Important
If you prefer to use a custom policy, this default policy must be disabled. Refer to Related Articles for details on how to create and enable custom Sandboxing policies.
-
Allow users to release emails - If enabled, messages to the end user also contain a link to the release delayed emails before the result from the sandbox is known; copies of attachments will still be analyzed; if the sandbox finds malicious attachments before this release link is used, the email cannot be released
- If disabled, messages to the end user will not contain a release link
- Send delay notifications - If enabled, notifications about delayed mail will be sent
