throttled based on the receiving control defined in mail flow policies. Specifying 
this recipient to bypass receiving control in a listener’s RAT allows the listener to 
receive unlimited messages for the recipient “
postmaster@domain
” while 
retaining mail flow policies for other recipients in the same domain. Recipients 
will avoid being counted against the recipients-per-hour counter maintained by 
the system if the sending domain is being limited.
To specify certain recipients to bypass receiving control via the GUI, select “Yes” 
for Bypass Receiving Control when adding or editing a RAT entry:

Bypassing Receiving Control
To specify certain recipients to bypass receiving control via the CLI, answer yes 
to the following question when you enter recipients using the 
listenerconfig -> 
edit -> rcptaccess
 command: 
Bypassing LDAP Accept for Special Recipients
If you configure LDAP acceptance queries, you may wish to bypass the 
acceptance query for certain recipients. This feature can be useful if there are 
recipients for whom you receive email which you do not want to be delayed or 
queued during LDAP queries, such as 
customercare@example.com
If you configure the recipient address to be rewritten in the work queue prior to 
the LDAP acceptance query, (such as aliasing or using a domain map), the 
rewritten address will not bypass LDAP acceptance queries. For example you use 
an alias table to map 
customercare@example.com
 to 
bob@example.com
 and 
sue@example.com
. If you configure bypassing LDAP acceptance for 
customercare@example.com
, an LDAP acceptance query is still run for
 
bob@example.com
 and 
sue@example.com
 after the aliasing takes place. 
To configure bypassing LDAP acceptance via the GUI, select Bypass LDAP 
Accept Queries for this Recipient 
when you add or edit the RAT entry.
