Suivre les sessions SMTP de messagerie sortante à partir de l'ESA

Introduction

Ce document décrit comment suivre et afficher une conversation électronique complète à partir de votre appliance de sécurité de la messagerie Cisco (ESA).

Suivre les sessions SMTP de messagerie sortante par domaine de destinataire

Les journaux de débogage de domaine vous permettent de suivre une conversation SMTP (Simple Mail Transfer Protocol) complète entre votre ESA et le domaine/hôte de destination. Chaque ligne du journal de débogage du domaine présente les données envoyées (envoyées) et reçues (Rcvd) au cours de la conversation SMTP.

Entrez la commande logconfig dans l'interface CLI de l'ESA afin de configurer la journalisation de sorte que l'ESA enregistre un journal de débogage de domaine pour le domaine destinataire concerné :

Choose the operation you want to perform:
- NEW - Create a new log.
- EDIT - Modify a log subscription.
- DELETE - Remove a log subscription.
- SETUP - General settings.
- LOGHEADERS - Configure headers to log.
- HOSTKEYCONFIG - Configure SSH host keys.

Note: Assurez-vous de valider toutes les modifications après la configuration du journal de débogage du domaine.

Le journal est actif pour le nombre de sessions que vous configurez pour le domaine. Afin d'afficher la trace de la conversation par e-mail en direct, entrez la commande tail example.com.domain.debug dans l'interface de ligne de commande ESA.

Voici un exemple de journal de débogage de domaine qui est généré lorsque l'ESA livre un message au domaine destinataire exemple.com :
