Overview
Log Types
The log type indicates what information will be recorded within the generated log such as message data, 
system statistics, binary or textual data. You select the log type when creating a log subscription. See 
 for more information.
Cisco IronPort AsyncOS for Email generates the following log types:

Log Types 
Log
Description
IronPort Text Mail Logs
Text mail logs record information regarding the operations of the email 
system. For example, message receiving, message delivery attempts, open 
and closed connections, bounces, TLS connections, and others.
qmail Format Mail Logs
qmail format delivery logs record the same information regarding the 
operations of the email system as delivery logs following, but stored in qmail 
format. 
Delivery Logs
Delivery logs record critical information about the email delivery operations 
of the Cisco IronPort appliance — for example, information regarding each 
recipient delivery and bounce at the time of the delivery attempt. 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. Delivery logs are recorded in 
a binary format for resource efficiency. Delivery Log files must be 
post-processed using a provided utility to convert them to XML or CSV 
(comma-separated values) format. The conversion tools are located at:

Bounce Logs
Bounce logs record information about bounced recipients. The information 
recorded for each bounced recipient includes: the message ID, the recipient 
ID, the Envelope From address, the Envelope To address, the reason for the 
recipient bounce, and the response code from the recipient host. In addition, 
you can choose to log a fixed amount of each bounced recipient message. 
This amount is defined in bytes and the default is zero.
Status Logs
This log file records system statistics found in the CLI status commands, 
including 
status detail
 and 
dnsstatus
. The period of recording is set 
using the 
setup
 subcommand in 
logconfig
. Each counter or rate reported in 
status logs is the value since the last time the counter was reset.
Domain Debug Logs
Domain debug logs record the client and server communication during an 
SMTP conversation between the Cisco IronPort appliance and a specified 
recipient host. This log type can be used to debug issues with specific 
recipient hosts. You must specify the total number of SMTP sessions to 
record in the log file. As sessions are recorded, this number decreases. You 
can stop domain debug before all sessions have been recorded by deleting or 
editing the log subscription.
Injection Debug Logs
Injection debug logs record the SMTP conversation between the Cisco 
IronPort appliance and a specified host connecting to the system. Injection 
debug logs are useful for troubleshooting communication problems between 
the Cisco IronPort appliance and a host on the Internet.
System Logs
System logs record the following: boot information, DNS status information, 
and comments users typed using 
commit
 command. System logs are useful 
for troubleshooting the basic state of the appliance.
