Reading e-mails on text mode

[Ricardo Gabriel Herdt <ricgh@matrix.com.br>]

          Debianers,

        Could you send me information to explain step-by-step how
configure, fetch and read e-mails on text mode, like for example, using mutt.
Or, at least, indicate me where to find information about this.
  
                Thanks,
