SMTP Libcurl

Hi ,

Libcurl is a utility tool which we can also send e-mails using SMTP library. Below is a sample program which helps you to do the same from Linux-C Language.

Below is the program
================

#include <stdio.h>

#include <string.h>

#include <curl/curl.h>

int main(void)

{

  CURL *curl;

  CURLcode res;

  FILE *FP;

  struct curl_slist *recipients = NULL;

  static const char *from = "********@gmail.com";

  static const char *to = "********@gmail.com";

  FP=fopen("/tmp/Email","r");

  curl = curl_easy_init();

  if(curl) {

    curl_easy_setopt(curl, CURLOPT_URL, "smtp://smtp.gmail.com:587");

    curl_easy_setopt(curl, CURLOPT_USE_SSL, CURLUSESSL_ALL);

    curl_easy_setopt(curl, CURLOPT_USERNAME, "From_Email_User@gmail.com");

    curl_easy_setopt(curl, CURLOPT_PASSWORD, "*********");

    curl_easy_setopt(curl, CURLOPT_MAIL_FROM, from);

    recipients = curl_slist_append(recipients, to);

    curl_easy_setopt(curl, CURLOPT_MAIL_RCPT, recipients);

    curl_easy_setopt(curl, CURLOPT_READDATA, FP);

    curl_easy_setopt(curl, CURLOPT_VERBOSE, 1);

    res = curl_easy_perform(curl);

    if(res != CURLE_OK)

      fprintf(stderr, "curl_easy_perform() failed: %s\n",curl_easy_strerror(res));

    curl_slist_free_all(recipients);

    curl_easy_cleanup(curl);

  }

  return 0;

}
