- Sat May 30, 2015 10:33 pm #19003 I checked some of the libraries for email on Arduino and it looks like most of them are designed for an ethernet shield or deprecated (or both).

Can anyone suggest a email library which will work on the ESP8266?

- Sun May 31, 2015 5:12 am #19020 I hav'nt looked at this yet but if you take a sketch for ethernet then the ESP makes just exactly the same connection to your router but without the cable .

Most of the email stuff should be useable I would think

- Tue Jun 02, 2015 1:44 pm #19256 From my testing so far, it's not usable.

Maybe you can give me a hand . I've gotta stop for a while .
If you put it on your ESP8266 you must change where I have deleted my personal stuff and put yours in . Its pretty scrappy cause I need to see where it hangs.

It seems I can get it to connect but I'm not getting a response from yahoo yet .I think it needs a secure SSL but i've gotta sort that yet
Read that the public mail servers don't let you in so maybe its going to have to be an ISP provided one.
