Managing the Email Queue
To temporarily suspend email delivery for maintenance or troubleshooting, use the suspenddel
command. The suspenddel command puts Cisco IronPort AsyncOS into suspended delivery state. This
state is characterized by the following:
Outbound email delivery is halted.
Inbound email connections are accepted.
Log transfers continue.
The CLI remains accessible.
The suspenddel command lets open outbound connections close, and it stops any new connections from
opening. The suspenddel command commences immediately, and allows any established connections to
successfully close. Use the resumedel command to return to regular operations from the suspended
delivery state.
Note 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.
