Buenos días, grupo zimbra, gracias por la ayuda.
Hace uno días, empece a revisar los log del zimbra 6 q tengo instalado en centos 5, pero me causo curiosidad que hay registros que no entiendo y son como preocupantes:
PRIMER REGISTRO:

Dec 4 08:12:27 Server postfix/smtpd[20369]: disconnect from unknown[IP-SERVER-PUBLICA]
SEGUNDO REGISTRO ES:
