Plesk allows us to control the outgoing queue from our server and know if our emails are being sent to their recipients.
Firstly, it is necessary to access our Plesk panel.
In Tools & Settings, we will have to go to the Mail section and then click on Mail Server Settings.
Once inside, we just have to click on the Mail Queue tab.
In this new window, we can see the emails that are in the queue of our server.
This simple tool will allow us to easily and quickly detect any incidents in the sending of our emails.
