with the node-red email do I need to set any thing else up so that it is able to send to my local SMTP server that is on the same network I know how to configure the smtp server (windows).
but I dont know how the Pi see the smtp server on my existing network (yes I know what it's IP address is)
the node-red email is sending the message but it does not get to my local server
that's the problem it does not appear to get there (it could be the sending address issue but I cant see where you specify who the email has come from)
Are you saying that if you don't set msg.from then the email node says it has sent ok but it never gets to the server? That sounds odd. I can imagine it getting rejected by the server but I would have expected that to be noted at the server and at the node (I think).
If you click on the node then click the i tab in te right hand pane it will show you the info for the node. In there is tells you which properties it uses. For how node-red all fits together look at the node-red docs where you will find a lot of useful stuff. For the specific issue you raise there is a section Working With Messages in the User guide, but it would be worth looking through the whole guide.
