Another way that you can tell people about yourself, or your company, is
to customize the headers that are sent in your mail and news messages.
Mail headers are specified in RFC822 and news headers are specified in
RFC1036.  The headers that you are most likely to want to customize
are the From, Reply-To, and Organization headers.  

READING MESSAGES
================
Most mailers and newsreaders do not display all the headers when you
are reading a message you've received.  Often typing `h' or ^h (for
header) will display all the headers of a message.  You can often set
up your mailer or newsreader to always automatically display whatever
headers you specify.


COMPOSING MESSAGES
==================
The sections below give instructions for automatically having
customized headers included in your messages.  Some composers will
automatically display your customized headers while you are
composing, and others won't.
