Cisco Cisco Email Security Appliance C160 Guía Del Usuario

If enabled, will allow partial domains. Partial 
domains can be no domain at all, or a domain with 
no dots.

The following addresses are examples of partial 
domains:

foo

foo@

foo@bar

This option must be enabled in order for the 
Default Domain feature to work properly.

Add Default Domain: A default

 

domain to use for 

email addresses without a fully qualified domain 
name. This option is disabled unless Allow Partial 
Domains is enabled in SMTP Address Parsing 
options (see 

). This affects how a listener modifies 

email that it relays by adding the “default sender 
domain” to sender and recipient addresses that do 
not contain fully-qualified domain names. (In 
other words, you can customize how a listener 
handles “bare” addresses). 

If you have a legacy system that sends email 
without adding (appending) your company’s 
domain to the sender address, use this to add the 
default sender domain. For example, a legacy 
system may automatically create email that only 
enters the string “

joe

” as the sender of the email. 

Changing the default sender domain would append 
“

@yourdomain.com

” to “

joe

” to create a 

fully-qualified sender name of 

joe@yourdomain.com

.
