 ## Change log
+ - 20/05/2022: v3.0.1 Put inside scope the client declaration (if you don't use SSLClient) for backward compatibility
  - 18/05/2022: v3.0.0 Add STM32 support. Add SSLClient integration to allow send Email with SSL encryption (like Gmail) with ethernet (tested with STM32, ESP32, w5500, and enc28j60), minor fix
  - 12/04/2021: v2.4.3 Fix multiple email send
  - 12/04/2021: v2.4.1 Add support for LITTLEFS and Ffat on esp32 and fix certificate verification from esp32 core 1.0.5
