This is not a bug report, this is a nodemcu version and half of a conversation with a SMTP server.

chathurangawijetunge commented 2 years ago

yes it is not a firmware bug, but it is a example code error....

HHHartmann commented 2 years ago

Seems like the example does not support tls but the server requires it. Maybe just state the limitation to the documentation of the example. Please use our template next time.
