Sending Emails via Windows Live Account

Projects Programming

I'am trying to send Emails using Ardino Uno+ Ethernet Shield based on Windows live account via SMTP and my code is

#include <SPI.h>
#include <Ethernet.h>

// this must be unique
byte mac[] = { 0x90, 0xA2, 0xDA, 0x00, 0x59, 0x67 };  

char message1[35], message2[35];
char subject[] = "ARDUINO: ALERT!!\0";
int time =1000;
// change server to your email server ip or domain
char server[] = "smtp.live.com";

EthernetClient client;

void setup()
{
  Serial.begin(9600);
  Ethernet.begin(mac);
  delay(2000);
  Serial.println(F("Ready. Press 'e' to send."));
}

void loop()
{
  byte inChar;

  inChar = Serial.read();

  if(inChar == 'e')
  {
   Serial.println("Arduino Mail");
   char message1[] = "Arduino auto genarated mail\0";
   char message2[] = "High Threshold Exceeded\0";
   sendEmail(subject, message1, message2, tempC);
} 
  }


void sendEmail(char subject[], char message1[], char message2[], float temp) 
{
Serial.println("connecting...");
if (client.connect(server,587)) 
{
Serial.println("connected");
client.println("EHLO knuckles.lk"); 
delay(time); // log in
client.println("STARTTLS");
delay(time);
client.println("AUTH LOGIN"); 
delay(time); // authorise

// enter your username here
client.println("info@knuckles.lk"); 
delay(time);
// and password here
client.println("XXXXXXXXXXX"); 
delay(time);

client.println("MAIL FROM:<info@knuckles.lk"); 
delay(time);
client.println("RCPT TO:<kasun@knuckles.lk>"); 
delay(time);

client.println("DATA"); delay(time);

client.println("From: <info@knuckles.lk>");
delay(time);
client.println("To: <kasun@knuckles.lk>"); 
delay(time);
client.print("SUBJECT: ");

client.println(subject); 
delay(time);
client.println(); 
delay(time);
client.println(message1);
delay(time);
client.println(message2); 
delay(time);
client.println("."); 
delay(time);
client.println("QUIT"); 
delay(time);
Serial.println("Email sent.");
delay(time);
checkEmail();
} 
else 
{
Serial.println("connection failed");
}
}
void checkEmail() 
{ 
  // see if any data is available from client
while (client.available()) 
{
char c = client.read();
Serial.print(c);
}
if (!client.connected()) 
{
Serial.println();
Serial.println("disconnecting.");
client.stop();
}
}

Server Response as below ........

Ready. Press 'e' to send.
Arduino Mail
connecting...
connected
Email sent.

220 2.0.0 SMTP server ready

But it doesn't send any mails to the specified mail account, what could be the wrong with this code....

250-STARTTLS

The email server is telling your Arduino it must start TLS, and the Arduino library doesn't support that type encryption.

Any Idea How to resolve this ..... or any other suggestions to send mails from Windows Live or Gmail without having any help of a PC ?

Any Idea How to resolve this

  1. Use something other than an Arduino
  2. Use an insecure mail service
