Cisco Cisco Email Security Appliance C690 User Guide

Processing for LDAP recipient access, masquerading, LDAP re-routing, Message 
Filters, anti-spam, and the anti-virus scanning engine are all performed in the 
“work queue.” Refer to “Configuring Routing and Delivery Features” in the Cisco 
IronPort AsyncOS for Email Advanced Configuration Guide for the processing 
flow and 

 for a description of the “Messages in Work Queue” 

gauge. You can manually pause the work queue portion of message processing 
using the 

workqueue

 command. 

For example, assume that you wanted to change the configuration of an LDAP 
server configuration while many messages are in the work queue. Perhaps you 
want to switch from bouncing to dropping messages based on an LDAP recipient 
access query. Or perhaps you want to pause the queue while you manually check 
for the latest anti-virus scanning engine definition files (via the 

antivirusupdate

 

command).The 

workqueue

 command allows you to pause and resume the work 

queue to stop processing while you perform other configuration changes. 

When you pause and resume the work queue, the event is logged. For example 

[1]> 1

Please enter the domain to schedule for immediate delivery.

[]> recipient.example.com
