I am using Email mode and in each email there is a link to visit the topic, but it also says I can use Reply to post a reply. I am using gmail via browser. I tried this but the email bounced with message below. The body was certainly longer than 20 characters:
We’re sorry, but your email message to [“email@example.com”] (titled Re: [Node-RED Forum] [Meta] Email mode and max email limit) didn’t work.
Body is too short (minimum is 20 characters)
If you can correct the problem, please try again.
