White space, punctuation, and, in the case of the 250 response, the OK characters are stripped from 
the beginning of the string. Only white space is stripped from the end of the string. For example, 
Cisco IronPort appliances, by default, respond to the DATA command with this string: 

250 Ok: 

Message MID accepted

. So, the entry “Message MID accepted” would be logged if the remote host 

were another Cisco IronPort appliance. 

Original Subject Header: When this option is enabled, the original subject header of each message 
is included in the log.

In some cases, it is necessary to record the presence and contents of a message’s headers as they pass 
through the system. You specify the headers to record on the Log Subscriptions Global Settings page (or 
via the 

logconfig

 -> 

logheaders

 subcommand in the CLI). The Cisco IronPort appliance records the 

specified message headers in the text mail logs and the tracking logs. If the header is present, the system 
records the name of the header and the value. If a header is not present, nothing is recorded in the logs.

The system evaluates all headers that are present on a message, at any time during the processing of the 
message for recording, regardless of the headers specified for logging.

The RFC for the SMTP protocol is located at 



http://www.faqs.org/rfcs/rfc2821.html

 and defines user-defined headers. 

If you have configured headers to log via the 

logheaders

 command, the header information appears after 

the delivery information:

For example, specifying “date, x-subject” as headers to be logged causes the following line to appear in 
the mail log:

Tue May 31 10:14:12 2005 Info: Message done DCID 0 MID 3 to RID [0] [('date', 'Tue, 31 May 

2005 10:13:18 -0700'), ('x-subject', 'Logging this header')]

Click the Edit Settings button in the Global Settings section of the Log Subscriptions page.
