Abstract:

The information includes initial information and descriptive information. The initial information is sent to a destination. A determination is made whether the destination has a file that matches the attachment based on the initial information. The attachment is sent to the destination if the destination does not have the file. The descriptive information is sent to the destination if the destination has the file. A determination is made whether the file matches the attachment based on the descriptive information. The attachment is sent to the destination if the file does not match the attachment based on the descriptive information.
