Hey Guys, I have installed the osticket system successfully on our server and has sat up all what we need. And now we need to use the notification for any ticket or replying happen, so I tried to add a new email to use it but it keeps show me an error message "Failed to connect to xxxxxxxx ". So, Can anyone please give an assist to fix this issue and to add an email to send the notifications. Note: the system is installed on centos os + trying to add an email from our domain "not gmail account". Thanks in advance.
