InterScan™ Messaging Security Appliance (IMSA) can analyze MIME file types to determine whether to take action on an email message based on the type of attachment.
To select MIME content type scanning conditions:
Under Attachment on the scanning conditions selection screen, select the check box next to MIME content type.
Click MIME content type. The Attachment MIME Type screen appears.
Next to Select, select one of the following:
Selected attachment types—IMSA takes action on email messages with attachments of the selected types.
Not the selected attachment types—IMSA takes action on email messages with attachments which are not of the selected types.
Select the check boxes next to the MIME content types to filter.
To add your own MIME types, type them in the text box. Use a semicolon (;) to separate values.
Click Save to continue selecting scanning conditions.
