Traccia sessioni SMTP posta in uscita dall'ESA
Sommario
Introduzione
Questo documento descrive come tracciare e visualizzare un'intera conversazione e-mail da Cisco Email Security Appliance (ESA).
Traccia sessioni SMTP posta in uscita per dominio destinatario
I log di debug del dominio consentono di tracciare un'intera conversazione SMTP (Simple Mail Transfer Protocol) tra l'ESA e il dominio/host di destinazione. Ogni riga del log di debug del dominio descrive i dati inviati (inviati) e ricevuti (ricevuti) durante la conversazione SMTP.
Immettere il comando logconfig nella CLI dell'ESA per configurare la registrazione in modo che l'ESA registri un log di debug del dominio del destinatario interessato:
