Tool 189: SMTP server

Description:

  This tool is a SMTP server. It only stores commands and messages
  in a local directory. It does not try to forward messages.
  
  Parameter --allowed-clients lists the IP addresses or hosts allowed
  to connect.
  Parameter --src-port defines the local port number to listen on.
  Optional parameter --src-ip defines the local IP address to use.
  Optional parameter --iptype defines which kind of IP address to use
  when --src-ip is unset (accepted values: ip4 and ip6).
  Optional parameter --ip4opts permits to add IP4 options encoded as
  mixed.
  Optional parameter --ip6exts permits to add IP6 options encoded as
  mixed (first byte is the next header number).
  Optional parameters --device and --src-eth are not yet implemented.
  
  This tool may need to be run with admin privilege in order to listen
  on a small port number (port<1024).
