This action applies if an email has an attachment that is a zipped file and that violates any of the following rules: • The zip file itself is too large ( > 500MB). • A file contained in the zip file is too large ( > 100MB). • The zip file contains too many files ( > 1500 files). • The compression rate is too high ( > 95% compressed). • The zip file contains too many levels of nesting ( > 3 levels). 6 From the Message contains an encrypted zip attachment drop-down menu, select one of the following options: • Allow delivery - Email Protection sends the email to the recipient with no filtering or notification. • Quarantine the message - Email Protection sends the email to quarantine. • Deny delivery - Email Protection denies delivery of the email. The action applies if an email message has an attachment that is a zipped file and is encrypted and password-protected. This format is commonly used to prevent scanning for viruses in zipped files. 7 From the File in zip attachment violates attachment policy drop-down menu, select one of the following options. • Attachment policy action - The action for the specific policy that was violated will be performed on the entire attachment.
