Suspending Receiving
To temporarily suspend all listeners from receiving email, use the

connections, respond with the following responses and disconnect:

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.
