/*
 * EMailSender library for Arduino, esp8266 and esp32
 * Arduino Mega and UIPEthernet send example with attach
 * this example is not tested for all, I can't find a provider
 * that manage attach without SSL and TLS
 *
 * Pay attention you must set in the library
 * #define DEFAULT_EMAIL_NETWORK_TYPE_ARDUINO 	NETWORK_ENC28J60
 * for UIPEthernet
 *
 * #define DEFAULT_EMAIL_NETWORK_TYPE_ARDUINO 	NETWORK_W5100
 * for standard Ethernet
 *
 * The base64 encoding of the image is slow, so be patient
