The Compose window, shown in Figure 4–4, is used to compose a new message. You can also use the window to save a draft or attach a file to the message, look up a recipient in the address book, access the help file, or cancel the composition altogether. Mail recipients can be added in “To”, “Cc”, or “Bcc” fields. You can edit the message in text or HTML format. In the Compose window you can also check the spelling. The Compose window also enables you to set the mail priority or request for a return receipt.
