Library to send EMail with attachments and STARTTLS (port 587) support via STM32 (w5500/enc28j60 + SSL, SPI Flash, SdFat2) Arduino SAMD (WiFiNINA, SD, SPI Flash, SdFat2), esp8266 (w5500/enc28j60 + SSL, SPIFFS, LittleFS and SD), esp32 (w5500/enc28j60 + SSLClient, WiFiClientSecure, SPIFFS, LITTLEFS, Ffat and SD), Raspberry Pi Pico (rp2040) (w5500/enc28j60 + SSL, SPIFFS, SPIFlash, LITTLEFS and SD). IMPORTANT: Arduino Mega/Uno do NOT support SSL/TLS due to RAM limitations (requires 24KB, available only 8KB/2KB). Use ESP32/ESP8266 for secure email.
