Introdução
Este documento descreve como gravar os encabeçamentos de mensagens processados através da ferramenta de segurança do email de Cisco (ESA).
Como fazem os encabeçamentos de mensagem de registro I?
Em alguns casos, é útil gravar a presença e os índices dos encabeçamentos de mensagem porque passam através do dispositivo. Você especifica os encabeçamentos para gravar através do logconfig > dos logheaders. O ESA gravará os cabeçalhos da mensagem especificados nos logs do correio de texto de IronPort, em logs da entrega de IronPort, e em logs do salto de IronPort. Se o encabeçamento esta presente, o sistema grava o nome do encabeçamento e do valor. A informação de cabeçalho recored após a informação de entrega.
Está abaixo um exemplo de como permitir o registro para gravar toda a mensagem com o X-IPA-resultado dos encabeçamentos e o X-IronPort-AV:
