quite often I see that my deliveries are in Retry pending status for a while. Because of that I have to wait for 10 minutes or even an hour before emails are sent. In Adobe's docs I found this page: https://docs.campaign.adobe.com/doc/AC/en/DLV_Tracking_deliveries_Monitoring_your_delivery.html.
According to it I should check if MTA modules are launched by type proper command: nlserver pdump. Next I should type: nlserver start mta@<INSTANCENAME>.
My question is quite basics: where I can type these commands? Where I can find console?
Thank you all!
