Cisco Cisco Email Security Appliance C650 用户指南

The sections of configuration tested by the 

trace

 command listed in 

 are performed in order. 

This can be extremely helpful in understanding how the configuration of one feature affects another. For 
example, a recipient address transformed by the domain map feature will affect the address as it is 
evaluated by the RAT. A recipient that is affected by the RAT will affect the address as it is evaluated by 
alias table, and so on. 

Host Access Table (HAT) and 
Mail Flow Policy Processing

The Host Access Table settings for the listener you specified are 
processed. The system reports which entry in the HAT matched from 
the remote IP address and remote domain name you entered. You can 
see the default mail flow policies and sender groups and which one 
matched the given entries. 

If the Cisco IronPort appliance was configured to reject the connection 
(either through a REJECT or TCPREFUSE access rule), the 

trace

 

command exits at the point in the processing. 

For more information on setting HAT parameters, see “Configuring 
the Gateway to Receive Email” in the Cisco IronPort AsyncOS for 
Email Configuration Guide. 

These sections summarize how the appliance configuration affects the Envelope Sender you supply. 
(That is, how the MAIL FROM command would be interpreted by the configuration of the appliance.) 
The 

trace

 command prints “

Processing MAIL FROM:

” before this section. 

Default Domain

If you specified that a listener to change the default sender domain of 
messages it receives, any change to the Envelope Sender is printed in 
this section. 

For more information, see “SMTP Address Parsing Options” in the 
Cisco IronPort AsyncOS for Email Advanced Configuration Guide. 

Masquerading

If you specified that the Envelope Sender of a message should be 
transformed, the change is noted here. You enable masquerading for 
the Envelope Sender on private listeners using the 

listenerconfig -> 

edit -> masquerade -> config 

subcommands. 

For more information, see “Configuring Masquerading” in the Cisco 
IronPort AsyncOS for Email Advanced Configuration Guide. 

These sections summarize how the appliance affects the Envelope Recipients you supply. (That is, how 
the RCPT TO command would be interpreted by the configuration of the appliance.) The 

trace

 

command prints “

Processing Recipient List:

” before this section.
