Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

IronPort AsyncOS allows you to filter incoming or outgoing messages and place 
them into quarantines. Quarantines are special queues or repositories used to hold 
and process messages. Messages in quarantines can be delivered or deleted, based 
on how you configure the quarantine.

The following Work Queue features can send messages to quarantines:

Message Filters

Anti-Virus

Virus Outbreak Filters

Content Filters

Messages released from quarantines are re-scanned for viruses.

See the “Quarantines” chapter of the Cisco IronPort AsyncOS for Email Daily 
Management Guide for more information. 

The delivery phase of the Email Pipeline focuses on the final phase of email 
processing, including limiting connections, bounces, and recipients.

The IronPort Virtual Gateway technology enables users to separate the IronPort 
appliance into multiple Virtual Gateway addresses from which to send and receive 
email. Each Virtual Gateway address is given a distinct IP address, hostname and 
domain, and email delivery queue.

For more information, see “Using Virtual Gateway™ Technology” in the 
“Configuring Routing and Delivery Features” chapter of the Cisco IronPort 
AsyncOS for Email Advanced Configuration Guide.
