Q
Queue
In the Cisco appliance, you can delete, bounce, suspend, or redirect messages in
the email queue. This email queue of messages for destination domains is also
referred to as the delivery queue. The queue of messages waiting to be processed
by IronPort Anti-Spam or message filter actions is referred to as the work queue.
You can view the status of both queues using the
the email queue. This email queue of messages for destination domains is also
referred to as the delivery queue. The queue of messages waiting to be processed
by IronPort Anti-Spam or message filter actions is referred to as the work queue.
You can view the status of both queues using the

R
RAT
Recipient Access Table. The Recipient Access Table defines which recipients
will be accepted by a public listener. The table specifies the address (which may
be a partial address or hostname) and whether to accept or reject it. You can
optionally include the SMTP response to the RCPT TO command for that
recipient. The RAT typically contains your local domains.

S
Sender Group
A sender group is simply a list of senders gathered together for the purposes of
handling email from those senders in the same way (that is, applying a mail flow
policy to a group of senders). A sender group is a list of senders (identified by
IP address, IP range, host/domain, SenderBase Reputation Service
classification, SenderBase Reputation score range, or DNS List query response)
separated by commas in a listener’s Host Access Table (HAT). You assign a
name for sender groups, as well as mail flow policies.
