In tin and the rn family of tools (Pnews, rn, trn, strn) you can use
environment variables to customize your headers.  These newsreaders
use the FROM, REPLYTO, and ORGANIZATION environment variables, if
they are set, to determine the From, Reply-To, and Organization headers.

The way you set an environment variable depends on which shell you
are using. For example, in the csh or tcsh you can set the
ORGANIZATION variable by putting the following line in you ~/.login:

  setenv ORGANIZATION "Your Organization Name"

After you edit your ~/.login you can establish the setting by either logging
out and loggin back in or by typing the following at your Unix prompt:

  source ~/.login

To check that the variable is set type:

  printenv

After you have set your environment variables, post a test message to
a local test newsgroup with `local' distribution to check that the
headers are correct.
