[linux-team] Sendmail et Relay



Hep ;-)
Dites, comment faire pour interdire le relay "non-local" avec sendmail ?
Sendmail, j'ai déjà chipoté un peu, mais il y a un bail, et notre (boulot)
serveur mail externe (Linux) avec Sendmail 8.8.8 est utilisé involontairement
comme relay, et un des admins m'a demandé comment on fait pour désactiver ça.

J'ai juste trouvé ceci dans /etc/mail/linux.mc:
dnl  "use_ip" is a list of IP addresses that are allowed to relay mail.
dnl  "use_names" is a list of domain names that are allowed to relay mail.
dnl  If your host accepts non-local email as relay for other sites, use
dnl  "use_relayto" to specify those sites.
dnl  To ban unauthorized relay, you have to use one or more of "use_ip",
dnl  "use_names" and "use_relayto". Always add the line with "check_rcpt4".
dnl
dnl HACK(`use_ip',`/etc/mail/LocalIP')dnl
dnl HACK(`use_names', `/etc/mail/LocalNames')dnl
dnl HACK(`use_relayto', `/etc/mail/RelayTo')dnl
dnl HACK(`check_rcpt4')dnl

Je dois décommenter use_ip et mettre l'IP de notre firewall dans /etc/mail/LocalIP ?
...sachant que notre configuration réseau est la suivante:

   +---+
   |lx |
   +---+
     |
   +---+
*--|fw |--LAN--
   +---+

*=internet ;-)

Puis un
  m4 /etc/mail/linux.mc > /etc/sendmail.cf
  rcsendmail reload
Ca suffit ou bien il y a d'autres astuces ?

merci ;-)
