Problème mail Postfix+Cyrus

["edoyuar reeri" <reolik@hotmail.com>]

Bonjour à tous,

j'aurrais besoin d'un petit coup de main, voilà ça fait quelques jours que 
j'ai configurer
mon serveur mail avec postfix+cyrus+squirrelmail en utilisant le tutorial
de http://www.linuxorable.net

J'ai ajouter mes comptes avec Cyrus normal, j'arrive à envoyer des mails à 
partir de squirrelmail,
mais pas a en recevoir sur mon serveur.

des que j'envoie un mail vers info@mondomaine.com, le compte 
info@mondomaine.com
ne le reçoit pas.
je ne sais pas si le problème vient du DNS chez ovh ou de postfix ou Cyrus.

voilà ma config DNS chez ovh.


.mondomaine.com   MX1                  smtp.mondomaine.com
smtp.mondomaine.com            A     mon ip Publique(fixe)
.mondomaine.com                   A     mon ip Publique(fixe)


Mes serveurs DNS:

                         ns.ovh.net
                  ns.mondomaine.com
