Cisco Cisco Email Security Appliance C160 Mode D'Emploi

* These features can send messages to special queues called Quarantines.

** Can send messages to the IronPort Spam Quarantine.

The receiving phase of the Email Pipeline involves the initial connection from the 
sender’s host. Each message’s domains can be set, the recipient is checked, and 
the message is handed off to the work queue.

The HAT allows you to specify hosts that are allowed to connect to a listener (that 
is, which hosts you will allow to send email). 

Sender Groups are used to associate one or more senders into groups, upon which 
you can apply message filters, and other Mail Flow Policies. Mail Flow Policies 
are a way of expressing a group of HAT parameters (access rule, followed by rate 
limit parameters and custom SMTP codes and responses).

Together, sender groups and mail flow policies are defined in a listener’s HAT.

1. Sets the default delivery interface. 

2. Sets the total maximum number of outbound 
connections. 

Defines, per-domain: maximum outbound 
connections for each virtual gateway and for the 
entire system; the bounce profile to use; the TLS 
preference for delivery: no/preferred/required

Routes mail based on domain without rewriting 
Envelope Recipient.

Drops recipients according to specific list 
(configured system-wide). 

Undeliverable message handling. Configurable per 
listener, per Destination Controls entry, and via 
message filters.
