In the following example, the 

domainmap

 subcommand of the 

listenerconfig

 

command is used to create a domain map for the public listener “InboundMail.” 
Mail for the domain and any subdomain of 

oldcompanyname.com

 is mapped to the 

domain 

example.com

. The mapping is then printed for confirmation. Contrast this 

example with the configuration of placing both domains in the listener’s RAT: the 
domain map feature will actually rewrite the Envelope Recipient of 

joe@oldcomapanyname.com

 to 

joe@example.com

, whereas placing the domain 

oldcompanyname.com

 in the listener’s RAT will simply accept the message for 

joe@oldcompanyname.com

 and route it without rewriting the Envelope Recipient. 

Also, contrast this example with the alias table feature. Alias tables must resolve 
to an explicit address; they cannot be constructed to map “any username

@domain

” 

to 

 

“the same username

@newdomain

.”
