Hi there everyone :)
When trying to setup an E-Mail notifications, with the configuration as follows:



I get this error:



The provided SMTP is from our ISP and only reachable from the internal network.
I have confirmed that I can reach it / send mail through it.
It does not require encryption / authentication.

I have tried different from / to addresses, so those are not the problem either.

I have retyped all addresses, to make sure there are not spaces anywhere.
Please advise what's wrong.

Cheers,
Dominik

Perhaps there is a firewall preventing SMTP or your provider requires a list of smtp agents to prevent smtp relay attacks.
