SMTP Support

[GeekDad66]

Does (or will) the SDK for the ESP32 support SMTP (Simple Mail Transfer Protocol)? I am looking at an application that would need to periodically send out a short (< 1Kb) status and the ESP32 looks like a nice solution if it does.

-Thanks-

SMTP is pretty easy, it is definitely possible. Not sure it will be a built-in function, but should be supported through arduino and nodemcu.

hi,

attached as an info
on YouTube is show an application that esp32 runs like you speek.
it spread on trigger or timerinterval or others simple or complex SMTP messages, in this to an Desktop eMail Server,
can be an ISP Server too and the messages get around the world to your handheld or other devices.
if you want realisze by your self,

you can try by the documents it is a simple Protokoll.
with lwip and freertos you can build fast this clients.

if you need more infos or help, let us know, how you will get on.

I didn't mean you have to use arduino or nodemcu, just that they already have libraries for SMTP. Good for noobs.

I give you until it support TLS and MIME attachments.
