Hi Melliesou,
I have the following enabled under TICKETS->SETTINGS->EMAILS:
-This is sent to the agent when they are assigned to a ticket.
-This is sent to agents when a new reply is received from a user.
-This is sent to the agent when a user closes a ticket.
I have checked the spam folder and I have also changed the ‘E-Mail Defaults’ to another email with no success.
I’m not sure how the user would get all the emails but the agents would not.
