You use the Message Window Properties to specify the number of lines in the View Message pop-up window text pane, a different print script for printing messages, and the headers that are not displayed when viewing a message with abbreviated headers.
To see the Message Window Properties, shown in Figure 4-34, choose Message Window from the Category menu at the top of the Properties popup window.
The Display field determines the number of Lines of Text displayed in each View Message or Compose window text pane. After you make a change and click SELECT on the Apply button, you will need to quit the Mail Tool and start it again for this change to take effect.
The Hide scrolling list determines which headers are not displayed when you view your messages with abbreviated headers. You can add any header to this list by typing the header in the Header Field text field, and clicking SELECT on the Add button.
Use the Add menu to place the header either before or after the currently selected header. Use the Delete button to delete the currently selected header, and use the Change button to change the currently selected header to the text typed in the Header Field text field.
Some of the headers that you might commonly want to hide are displayed in the scrolling list in Figure 4-34. You can add any header to the Hide list that you see when viewing messages. You can type the header in any case. For example, adding the header "content-length" hides the headers "Content-Length", "content-length", "CONTENT-LENGTH", and so forth.
When you have changed Message Window properties, click SELECT on the Apply button. The Print Script and Hide property settings become effective immediately.
