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

.

Determines behavior if source routing is detected in the “MAIL 
FROM” and “RCPT TO” addresses. Source routing is a special 
form of an email address using multiple ‘@’ characters to specify 
routing (for example: @one.dom@two.dom:joe@three.dom). If 
set to “reject,” the address will be rejected. If “strip,” the source 
routing portion of the address will be deleted, and the message 
will be injected normally.
