Email node credentials is not persisting in node-red

I was using the 'email' out node in node-red and sending emails, but suddenly it stopped working and giving me the following error:

So I dug into the node-red-node-email module [https://www.npmjs.com/package/node-red-node-email] and look up the code, and found that:

...

var globalkeys = RED.settings.email || require(process.env.NODE_RED_HOME+"/../emailkeys.js");

...

var flag = false;
        if (this.credentials && this.credentials.hasOwnProperty("userid")) {
            this.userid = this.credentials.userid;
        } else {
            if (globalkeys) {
                this.userid = globalkeys.user;
                flag = true;
            }
        }
        if (this.credentials && this.credentials.hasOwnProperty("password")) {
            this.password = this.credentials.password;
        } else {
            if (globalkeys) {
                this.password = globalkeys.pass;
                flag = true;
            }
        }
        if (flag) {
            RED.nodes.addCredentials(n.id,{userid:this.userid, password:this.password, global:true});
        }

https://github.com/node-red/node-red-nodes/blob/master/social/email/61-email.js#L25

So if we set the email credentials in RED.settings (this file - https://github.com/node-red/node-red/blob/master/settings.js), it will use that email credentials to send the email properly:

email: {
  user: '[email protected]',
  pass: 'password'
}

and it will persist in all environments.
