Cisco Cisco Email Security Appliance C160 Mode D'Emploi

The “delivery suspend” state is preserved across system reboots. If you use the 

suspenddel

 command 

and then reboot the appliance, you must resume delivery after the reboot using the 

resumedel

 command. 

The 

resumedel

 command returns Cisco AsyncOS to normal operating state after using the 

suspenddel

 

command.

resumedel

To temporarily suspend all listeners from receiving email, use the 

suspendlistener

 command. While 

receiving is suspended, the system does not accept connections to the specific port of the listener. 

This behavior has changed in this release of AsyncOS. In previous releases, the system would accept 
connections, respond with the following responses and disconnect:

SMTP: 

421 

 Service not available, closing transaction channel

QMQP: 

ZService not available

The “receiving suspend” state is preserved across system reboots. If you use the 

suspendlistener

 

command and then reboot the appliance, you must use the 

resumelistener

 command before the listener 

will resume receiving messages.
