RELAY

Connection is accepted. Receiving for any recipient is allowed and is not 
constrained by the Recipient Access Table.

CONTINUE

The mapping in the HAT is ignored, and processing of the HAT continues. If 
the incoming connection matches a later entry that is not CONTINUE, that 
entry is used instead. The CONTINUE rule is used to facilitate the editing of 
the HAT in the Graphical User Interface (GUI). For more information, see 

. 

In addition to these basic access control parameters, the following parameters are 
available for listeners you create. Parameters combined with an access rule 
(ACCEPT or REJECT) are called mail flow policies. A mail flow policy is a way 
of expressing a group of HAT parameters (access rule, followed by connection 
parameters, rate limiting parameters, custom SMTP codes and responses, and 
anti-spam, anti-virus, encryption, and authentication parameters). 

Mail flow policies are then mapped to sender groups as entries in a listener’s 
HAT.
