Cisco Cisco Email Security Appliance C390 사용자 가이드

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 IronPort. 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:
