See SYNOPSIS in Mail::Message::Body
The body (content) of a message can be stored in various ways. In this documentation you find the description of extra functionality you have when a message is stored in a file.
Storing a whole message is a file is useful when the body is large. Although access through a file is slower, it is saving a lot of memory.
