Bloccare l'invio di messaggi in postfix
Per bloccare il delivery delle mail in uscita:
- The more complete solution to disable the scheduler while allowing mail to arrive as usual:
sudo postconf -e master_service_disable=qmgr.fifo in_flow_delay=0 sudo invoke-rc.d postfix reload
- To re-enable the scheduler and queue flooding safety:
sudo postconf -e master_service_disable= in_flow_delay=1 sudo invoke-rc.d postfix reload
