  • There is no state required, SMTP is a very simple protocol and you can pre-program the entire client side of the conversation, only waiting to see OK from the server and dropping the connection if anything looks different to what you expect.The only problem with trying to use the Arduino for SMTP will be those servers that insist on using SSMTP or SMTP/SSL. Base64 encoding is simple.
