How can I encrypt the Node-RED email login?

Question

I'm using Node-RED in IBM's Bluemix. There are nodes to get email in and send email out. However, the email credentials do not seem to be encrypted when sent over the internet. I'm a bit concerned about that. Is there a way to find email receive and email send nodes for Node-RD where they login to the email server using TLS (or SSL)?

Answer 1

If you configure the email nodes to point at SSL/TLS ports then they will connect via a secure channel.

Also I believe that if the mail servers support the STARTTLS command then they will upgrade the connection once connected.
