Inbound MailSafe protection

Potentially dangerous attachments can be identified by their file name extensions-the characters that appear after the "dot" in a file name. They identify the file type so that the appropriate program or system component can open it.

For example:

.exe (an executable file)


.js (a JavaScript file)


.bat (a batch process file)

When an e-mail message with an attachment arrives in your Inbox, MailSafe examines the attachment's file name extension and compares it to the extensions on the attachments list. If the attachment type appears on the list and if attachments of that type are set to quarantine, Zone Labs security software changes the file name extension to ".zl*" (where * is a number or letter).

Changing the filename extension quarantines the attachment by keeping it from running automatically. When you open the e-mail containing the attachment, Zone Labs security software displays a MailSafe alert to let you know that it has quarantined the attachment. If you try to open the attachment, an alert warns you of the potential risk involved. However, you are still able to open the attachment if you are sure that it is safe.

Inbound MailSafe protection works with any e-mail application that uses POP3 or IMAP protocols. .

Inbound MailSafe protection is designed for local access only. If you have configured your POP3 client for remote access, inbound MailSafe protection may not be available.
