esp32 Storage supported - SD - SPIFFS

Constructor: Default value is quite simple and use GMail as smtp server.

	EMailSender emailSend("smtp.account@gmail.com", "password");

If you want use onother provider you can use more complex (but simple) contructor

	EMailSender(const char* email_login, const char* email_password, const char* email_from, const char* smtp_server, uint16_t smtp_port);

You must connect to WIFI :P.

Create a message with the structure EMailMessage

    EMailSender::EMailMessage message;
    message.subject = "Subject";
    message.message = "Hi, How are you<br>Fine.";

Create array of attachments

// 		Two file
    EMailSender::FileDescriptior fileDescriptor[2];
    fileDescriptor[1].filename = F("test.txt");
    fileDescriptor[1].url = F("/test.txt");
    fileDescriptor[1].storageType = EMailSender::EMAIL_STORAGE_TYPE_SD;

    fileDescriptor[0].filename = F("logo.jpg");
    fileDescriptor[0].url = F("/logo.jpg");
    fileDescriptor[0].mime = "image/jpg";
    fileDescriptor[0].encode64 = true;
    fileDescriptor[0].storageType = EMailSender::EMAIL_STORAGE_TYPE_SD;

    EMailSender::Attachments attachs = {2, fileDescriptor};

Send message:

    EMailSender::Response resp = emailSend.send("account_to_send@gmail.com", message, attachs);

Then check the response:

    Serial.println("Sending status: ");
    Serial.println(resp.code);
    Serial.println(resp.desc);
    Serial.println(resp.status);

Example output:

Connection: ESTABLISHED
Got IP address: 192.168.1.104
Sending status: 
1
0
Message sent!
