Attachment Filter


  • Click 'Modules' > 'Anti-spam' > 'Attachment Filter' tab.
  • This area lets you define how many archive levels should be checked by Secure Email Gateway.
  • For example, a zip file may contain another zip file inside it. A depth of '2' means Secure Email Gateway will check inside both files. However, if the 2nd zip contains another zip inside it, then Secure Email Gateway will block the entire attachment.



  • Maximum depth for archive files for attachment analysis: Max. archive levels that will be analyzed. Enter the maximum number of nested archives which should be opened and examined for data-leak infringements. If an archive contains more sub-archives than this threshold then the entire attachment will be blocked.
