ZipOut Attachment Security

ZipOut offers three attachment security features which can be set on the ZipOut Configuration dialog.

Block harmful attachments ZipOut will delete potentially harmful attachments from an Outlook item when it is saved or sent.
Warn when opening items that contain blocked attachments ZipOut will display a warning alert box if the Outlook item contains blocked attachments. Blocked attachments are known as Level 1 attachments, meaning attachments that are potential carriers for an e-mail worm or virus. These worms or viruses can range from troublesome to catastrophically destructive.
Check Zip for blocked files A warning message will be inserted into each compressed attachment that ZipOut creates, listing any blocked (Level 1) files that have been included in the attachment.

When Block harmful attachments is enabled attachments are blocked both through the user interface and programmatically. If a virus attempts to propagate itself by sending a virus payload attachment to other users, the attachment will be deleted from the message as long as the file type of the attachment appears in the Block Attachments list.

The following attachments will be deleted from an Outlook item that is saved or sent through Outlook whether or not attachment compression is currently enabled.

File attachments with an extension that appears in the Block Attachments list.
Embedded attachments such as Excel spreadsheets and Word documents. These attachments are inserted into a message by clicking in the body of a Microsoft Rich Text message and selecting the Object command on the Insert menu.
Attachments that are linked to a source file. A linked attachment displays a shortcut to the source file in the body of the message.
