Talking to myself I found a solution. I followed the guide: https://randomnerdtutorials.com/esp32-send-email-smtp-server-arduino-ide/ The link above works with GMail. Basically you have to set up 2-Step verification in you google account and then create an "App Password", which allows access with a ...

Sorry, I forgot to say, that I'm using ESP-IDF 5.2 and an ESP32.

I switched to a gmail account to be close to the example. There's another problem now.

Hi ESP_Sprite

Kind regards

Christian

Dear all

Thank you for the clarification.

I'm not sure where to make that suggestion... or maybe it's stupid anyway.

Ok, for who ever is intersted...

If you call esp_sntp_getserver(u8_t idx), all servers but the one that time was retrived from, return a 0 for IP address.

I could not find documentation... it's not for granted, that it works reliably.
