Hi and "moin moin" to everybody.

This is my first entry in this user forum.  
I seriously played around wih node-red for a few months now.

I developed several flows with an email sending node from the "node-red-node-email" packages Version "1.12.1".  
For general purpose i want to configure the Server, Authorization and port information for my SMTP-Server NOT within every single email-node.

Is there a way to pass those configuration values by message-in like topic, content , receiver and other variables in real-time?  
Actually I want to store these settings in global context to reuse them everywhere.

Help is very much appreciated!  
Thank you in advance.

Swen

I created a sub-flow with just the email node and the configuration and use the sub-flow instead of configuring the the email node every time. As far as I know, you cannot pass the configuration parameters into the node.

Hope this helps.

You can use environment variables like [Using environment variables : Node-RED](https://nodered.org/docs/user-guide/environment-variables) - but these are read once at deploy time - so are ok on a case by case basis - ie can be configured once externally - but are not fully dynamic.

Thanks!  
I took that in consideration already, but I wanted to avoid an "external" configuration setup.  
Cheers
