Memory usage describtion when using ESP-Mail-CLient per supported boards

[ardudi]

Is there ant document decribing memory usage and its mapping when using ESP-Mail-Client library, per a defined board platform?
I my case specifically, I am looking for such as document for Sending email using SMTP and receiving email using IMAP.

Nothing to map. It's dynamic memory allocation based on dynamic data instead of static allocation.

The most memory consumption is SSL engine used.

For ESP8266/ Pico with BearSSL library, 16k for rx buffer, 1k for tx buffer when connecting to IMAP server and 2k for rx buffer, 1k for tx buffer when connecting to SMTP server.

For ESP32 with mbedTLS library, 50k was reserved when connecting to IMAP and SMTP servers.

This example shows how to send and receive email with SMTP and IMAP server.

If you want to know the chip architecture. There are documentations from chip (mcu) manufacturer that you can learn.

This is quite off topic, and you should ask such question on community forum instead.
