Signature files are text files that are automatically added to the end of e-mail messages.
To create one, simply use any text editor such as Notepad. A signature file can be your name, your title, or a hyperlink to your web page. Save the file as a .txt file. Click on Options and go to the Mail and News preferences. Under the Identity tab, at the bottom, enter the location of the signature file.
