Hello,

I am working on a project where i want to send a mail when an avent happens. This is my code, but it doesn't send the mail and i don't know why..

Code: [Select]


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

// Change these next 4 entries to your network settings
byte mac[] = {  0x00, 0xAA, 0xBB, 0xCC, 0xDE, 0x02 };
char server[] = "smtp.ziggo.nl"; //smtp server ip address
EthernetClient client;

int button1 = 2; //button pin, connect to ground to move servo
int press1 = 0;

void setup()
{
  Serial.begin(9600);
  delay(10);
  // start the Ethernet connection:
  if (Ethernet.begin(mac) == 0) {
    Serial.println("Failed to configure Ethernet using DHCP");
    // no point in carrying on, so do nothing forevermore:
    while(true);
  }
  // give the Ethernet shield a second to initialize:
  delay(1000);
  Serial.println("connecting to network...");

 
  pinMode(button1, INPUT);
  digitalWrite(4, HIGH); //enable pullups to make pin high
 
  Serial.println("Ready");
}

void loop()
{
  byte inChar;
  inChar = Serial.read();
  press1 = digitalRead(button1);
     
  if(inChar == 'e')
  {
    if(sendEmail()) Serial.println("Serial Email sent"); //start sendEmail()
    else Serial.println("Serial Email failed");
  }

   if (press1 == HIGH)
  {
    delay(2000);
    if(sendEmail()) Serial.println("Button Email sent"); //start sendEmail()
    else Serial.println("Button Email failed");
  }
}

//////////////////////////////// email function
byte sendEmail()  //sendEmail() function that returns 1 or 0
{
  //start and check for email server connection
  if (client.connect(server,25)) {
    Serial.println("connected");
  }
  else {
    Serial.println("connection failed");
    return 0; //send 0 (failed) back to sendEmail() function
  }
 
  //wait for server "queing" response
  while(!client.available()) delay(1);

  client.println("HELO Arduino"); /*hello (statement after helo is needed but irrelevant)*/

  //wait for server "hello" response
  while(!client.available()) delay(1);

  client.println("MAIL From: somebody@gmail.com"); // identify sender, this should be the same as the smtp server you are using*/

  //wait for server "sender ok" response
  while(!client.available()) delay(1);

  client.println("RCPT To: somebody@gmail.com"); /* identify recipient */

  //wait for server "receipent ok" response
  while(!client.available()) delay(1);

  client.println("DATA");

  //wait for server to say "enter your message" response
  while(!client.available()) delay(1);

  //send email message to server
  client.println("To: somebody@gmail.com"); /* identify recipient */
  client.println("Subject: You Have Arduino Mail!!"); /* insert subject */
  client.println("Please let me know it worked!!!"); /* insert body */
  client.println("."); /* end email */

  //wait for server "message accepted" response
  while(!client.available()) delay(1);

  client.println("QUIT"); /* terminate connection */
 
  //wait for server "goodby" response
  while(!client.available()) delay(1);

  //stop client connection
  client.stop();
  Serial.println("disconnected");
  return 1; //send 1 (success) back to sendEmail() function
}


Anybody knows what i am doing wrong?

Thanks in advance,

it doesn't send the mail


Could you elaborate on this? You've got some debug statements in there that should tell you whether it tried to send the email and whether it succeeded. What do they tell you?
I only provide help via the forum - please do not contact me for private consultancy.

Here is an email sketch that actually displays what the email server is returning.
http://playground.arduino.cc/Code/Email
That may help you figure out why it is not working. Here is an example serial monitor display for a successful send.
