The sent message file contains any header lines included in the original message file, the date and time on which the message was sent, and the names of any attachment files sent with the message. These are followed by a separator line and the body text of the message.
The temporary file is then opened on the desktop using the program specified on the 'Editor' line of the 'settings.txt' file.
When the file is closed, RexxMail deletes the temporary file.
