Check for amount of files in archives
Screenshot 72 - Configuring the amount of files in archive check
This filter allows you to quarantine or delete emails that contain an
excessive amount of compressed files within an attached archive. You
can specify the number of files allowed in archive attachments from
the configuration options included in this filter.
To configure this filter:
1. Click the GFI MailSecurity  Decompression node.
2. From the list of filters (in the right window), click on Check for
amount of files in archives.
3. Select the Check for amount of files in archives check box to
enable this filter and specify the maximum amount of files allowed in
an archive.
IMPORTANT: If you disable the Check for amount of files in
archives rule, GFI MailSecurity will not scan or quarantine archive
attachments, thus bypassing the anti-virus checking.
4. Decide on what to do with emails containing archives that exceed
the specified limit of contained files by selecting one of the following
options:
 Quarantine – Select this option to quarantine the emails that
contain these archives. The administrator can later review these
quarantined emails and approve or delete them accordingly.
 Automatically Delete – Select this option to delete emails
containing archived files that when uncompressed contain more
files than the limit specified.
5. Click the Actions tab to configure any actions to be performed
whenever this filter detects and blocks emails containing an archive.
For more information on how to configure actions refer to the
„Configuring decompression filter actions‟ section in this chapter.
6. Click Apply.
Scan within archives
Through the Scan within archives option, you can disable
Attachment Checking and Content Checking of files in archives.
