Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

 defines a set of variables that can also be used in conjunction with the custom SMTP and Rate 

Limiting banners defined for a mail flow policy. Variable names are case-insensitive. (That is, 

$group

 is 

equivalent to 

$Group

.)

These variables can be used with the 

smtp_banner_text

 and 

max_rcpts_per_hour_text 

advanced HAT 

parameters shown in Table 1-3 of the “Customizing Listeners” chapter in the Cisco IronPort AsyncOS 
for Email Advanced Configuration Guide.

Using these variables, you could edit the custom SMTP banner response text for accepted connections 
in the $TRUSTED policy in the GUI:

Or like this, in the CLI: 

$Group

Replaced by the name of the sender group that was matched in the HAT. If the sender 
group has no name, “None” is displayed.

$Hostname

Replaced by the remote hostname if and only if is has been validated by the Cisco 
appliance. If the reverse DNS lookup of the IP address is successful but returns no 
hostname, then “None” is displayed. If the reverse DNS lookup fails (for example, if 
the DNS server cannot be reached, or no DNS server has been configured) then 
“Unknown” is displayed.

$OrgID

Replaced by the SenderBase Organization ID (an integer value).

If the Cisco appliance cannot obtain a SenderBase Organization ID, or if the 
SenderBase Reputation Service did not return a value, “None” is displayed.

$RemoteIP

Replaced by the IP address of the remote client. 

$HATEntry

Replaced by the entry in the HAT that the remote client matched.
