I installed PRTG today and am using the built-in mail server to send e-mail notifications. At the beginning I was only receiving the notifications sporadically and now I am not receiving them at all.
When I look at the notification log all the e-mails that failed to send have the message 'Status sending Email: "[email protected]" <[email protected]>: Relay access denied'
I disabled Windows Firewall completely and there is no antivirus running.
Does anyone have any ideas? Thank you very much.
