Mail delivery suspended.
The resumedel command returns Cisco IronPort AsyncOS to normal operating state after using the
suspenddel command.
resumedel
mail3.example.com> resumedel
Mail delivery resumed.
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 hostname Service not available, closing transaction channel
QMQP: ZService not available
Note 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.
