Hello Mesdames et Messieurs,
Je viens solliciter votre aide car je suis en passe d'avoir une calvitie suite à un problème avec postfix multi instance sur 4 IP qui sont UP sur mon serveur. (J'ai vraiment besoin de plusieurs IP pour envoyer)

J'ai suivi ce tuto (qui au passage n'utilise pas le multi-instance) mais je n'arrive pas à recevoir mes mails sur mon serveur mail...
J'ai ajouté 2 adresses mail via PostfixAdmin(abuse et admin), où j'arrive à me connecter via mon compte gmail sans pb, mais aucun mail n'arrive en boite et gmail me renvoie ce message d'erreur:

Final-Recipient: rfc822; abuse@MONDOM.net
Action: delayed
Status: 4.4.1
Diagnostic-Code: smtp; The recipient server did not accept our requests to connect.
J'ai testé si mon port 25 etait bien ouvert avec cette commande
netstat -tuplen | grep 25
Et apparement c 'est le cas:

tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 0 197288 2441/master
tcp 0 0 127.0.0.1:2527 0.0.0.0:* LISTEN 0 197279 2441/master

Petit récap, J'utilise PostFix, PostFixAdmin et Dovecot pour mon serveur mail, mon problème n'est pas sur l'envoie de mail mais sur la réception des mails pour pouvoir traiter les bounces et les désabonnements...
Je ne reçois mes mail ni sur root@MONDOM.net, ni sur abuse@MONDOM.net...

Je vous mets ci-dessous la conf de mes fichiers Main.cf et Master.cf
Merci par avance pour vos retours !
