Chapter 5      Configuring the Gateway to Receive Email
Defining Recipients
The RAT allows you to define a recipient or group of recipients. Recipients can 
be defined by full email address, domain, partial domain, or username:
Note
When you add a domain to the Recipient Access Table in step 4 of the System 
Setup Wizard in the GUI (see 
), you might want to 
consider adding a second entry to specify subdomains. For example, if you type 
the domain 
example.net
, you might also want to enter 
.example.net
. The second 
entry ensures that mail destined for any subdomain of 
example.net
 will match in 
the Recipient Access Table. Note that only specifying 
.example.com
 in the RAT 
will accept for all subdomains of 
.example.com
 but will not accept mail for 
complete email address recipients without a subdomain (for example 
joe@example.com). 
Bypassing Throttling for Special Recipients
For recipient entries, you can specify that the recipient bypasses throttling control 
mechanisms enabled on the listener. 
This feature is useful if there are certain recipients for whom you do not want to 
limit messages. For example, many users will want to receive email for the 
address “
postmaster@domain
” on a listener, even if the sending domain is being 
division.example.com
Fully-qualified domain name. 
.partialhost
Everything within the “partialhost” domain.
user@domain
Complete email address. 
user@
Anything with the given username. 
user@[IP_address]
Username at a specific IP address. Note that the IP 
address must be between the “
[]
” characters. 
Note that “
user@
IP_address” (without the bracket 
characters) is not a valid address. The system will 
append the brackets when it receives the message to 
create a valid address, which could affect whether a 
recipient is matched in the RAT.
