so, using the esp32 and the w5500, I would choose what option, and  // comment out the others?

in my sketch, can I add the following lines:

#define DEFAULT_EMAIL_NETWORK_TYPE_ESP32 NETWORK_ESP32

#define NETWORK_ESP32_ETH (5)

and not touch the emailsenderkey.h file?

emailsender.h has the following:

#elif(EMAIL_NETWORK_TYPE == NETWORK_ESP32_ETH)

#include <ETH.h>
#define EMAIL_NETWORK_CLASS WiFiClient
#define EMAIL_NETWORK_SERVER_CLASS WiFiServer

why? if it’s ethernet, why is wifi being called?

Progress:

Connection: ESTABLISHED
Got IP address: 10.0.160.182
Sending status:
Connection: ESTABLISHED

Could not connect to mail server

At least it compiles ….

It’s not connecting to my gmail account. It used to connect. email address and password have not changed. Gmail gave me an unknown device, access blocked message. I told it it was me. I’m no longer getting security messages, but there’s still no connection. gmail account set to allow insecure connections, no 2 factor.

“<b>Telnet smtp.gmail.com 465” from the same network works fine, with no errors.</b>

I’ve been using gmail for months. It’s been configured for unsecure, no 2 factor. It was working until I switched from wifi to ethernet. now it no longer works.
