Mail Tool messages are normally displayed with an abbreviated header. To display a message with the full message header, select the desired message header and choose Full Header from the Messages submenu of the View menu. Figure 4-5 shows an example of a full message header.
The contents of the abbreviated header are determined by the Hide items on the Message Window Properties scrolling list. All mail headers are displayed except those listed in the Hide scrolling list. See "Message Window Properties" for information about customizing your default abbreviated header with the Hide scrolling list.
