Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

Delivery logs record critical information about the email delivery operations of AsyncOS. The log 
messages are “stateless,” meaning that all associated information is recorded in each log message and 
users need not reference previous log messages for information about the current delivery attempt. 

The delivery log records all information pertaining to email delivery operations for each recipient. All 
information is laid out in a logical manner and is human-readable after conversion using a utility 
provided by Cisco. The conversion tools are located at:

Delivery logs are recorded and transferred in a binary format for resource efficiency. Information 
recorded in delivery logs is shown in the following table:
