Running ESET RA 5.0.242. I had originally set up a notification system that worked. It notified every time a PC received a threat. I noticed that it stopped sending the notifications, so I went to investigate, and I now receive the error message "Error Code 20270, 1" when I try to send a test email. I reset all the settings in the server options to no avail. Now, NOTHING has changed in my environment. I tested SMTP communication from the RA server, and I establish a connection without an issue. So, this error is most certainly software-related. Has anyone had this issue before? I would really like my notifications to start again, so I don't have to log in to see if there have been any threats.
