NethServer Version: nethserver-7.6.1810
I’ve now got my first SME > Nethserver migration working in a production environment. Need to get problems sorted out before I start on the other 8 systems…
Most things seem to be functioning as they should. However, on this systems, I have an account that I use for monitoring the other systems. All of them send email notifications to it. Which is working, but I’m having problems with quite a number of messages from the other systems being treated as spam. Seems fairly random when it comes to most of them, but annoying all the same.
I’ve attempted to whitelist the addresses of all the systems that normally send notification emails, using the web console - Email > Filter > Rules by mail address, where I’ve entered all the IPs of the affected systems. Hasn’t made the slightest difference. Some emails from most of the systems are still treated as spam.
Can anyone suggest what else I can do to avoid this problem?
