Glossary
IDE File Virus Definition File. An IDE file contains signatures or definitions used by
anti-virus software to detect viruses.
L
LDAP Lightweight Directory Access Protocol. A protocol used to access information
about people (including email addresses), organizations, and other resources in
an Internet directory or intranet directory.
Listener A listener describes an email processing service that will be configured on a
particular IP interface. Listeners only apply to email entering the Cisco IronPort
appliance — either from the internal systems within your network or from the
Internet. IronPort AsyncOS uses listeners to specify criteria that messages must
meet in order to be accepted and relayed to recipient hosts. You can think of a
listener as an “email injector” or even a “SMTP daemon” running for each IP
address you specify.
GL-4
IronPort AsyncOS differentiates between public listeners — which by default
have the characteristics for receiving email from the Internet — and private
listeners that are intended to accept email only from internal (groupware,
POP/IMAP, and other message generation) systems.
Log Subscription Creation of log files that monitor the performance of the Cisco IronPort
appliance. The log files are stored in local disk(s) and can also be transferred and
stored in a remote system. Typical attributes of a log subscription include: name,
component to monitor (email operations, server), format, and transfer method.
M
Mail Flow Policies A mail flow policy is a way of expressing a group of Host Access Table (HAT)
parameters (an access rule, followed by rate limiting parameters and custom
SMTP codes and responses) for a listener. Together, sender groups and mail
flow policies are defined in a listener’s HAT. Your Cisco IronPort appliance
ships with the predefined mail flow policies and sender groups for listeners.
MAIL FROM See Envelope Sender.

Maximum Time in
