Automatically mail send everyday in c from server

To send an email automatically every day from a C program running on a server, you'll need to use a library that can interact with a mail server. Here's a step-by-step guide to help you achieve this:

Prerequisites:

A C compiler (e.g., GCC) installed on your server.
A mail server set up on your server (e.g., Postfix, Sendmail, or Exim).
A library that can interact with the mail server. We'll use the libmail library, which is a C library that provides a simple way to send emails.

Step 1: Install the libmail library

On Ubuntu-based systems:

sudo apt-get install libmail

On Red Hat-based systems:

sudo yum install libmail

Step 2: Write the C program

Create a new file called send_email.c and add the following code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <libmail.h>

int main() {
    // Set up the mail server connection
    Mail *mail = mail_init("your.mail.server.com", 25); // Replace with your mail server's hostname and port

    // Set up the email message
    mail_set_from(mail, "[email protected]"); // Replace with your email address
    mail_set_to(mail, "[email protected]"); // Replace with the recipient's email address
    mail_set_subject(mail, "Daily Report"); // Replace with the subject of the email
    mail_set_body(mail, "This is a daily report sent automatically from your server.");

    // Send the email
    if (mail_send(mail) == 0) {
        printf("Email sent successfully!\n");
    } else {
        printf("Error sending email: %s\n", mail_strerror(mail));
    }

    // Clean up
    mail_free(mail);

    return 0;
}

Step 3: Compile the program

Compile the send_email.c file using the following command:

gcc -o send_email send_email.c -lmail

Step 4: Schedule the program to run daily

You can use a scheduler like cron to run the program daily. Open the cron table for editing:

crontab -e

Add the following line to schedule the program to run daily at 8:00 AM:

0 8 * * * /path/to/send_email

Replace /path/to/send_email with the actual path to the send_email executable.

Step 5: Test the program

Save the changes to the cron table and test the program by running it manually:

/path/to/send_email

If everything is set up correctly, you should receive an email with the subject "Daily Report" and the body "This is a daily report sent automatically from your server."

That's it! Your C program should now send an email automatically every day at 8:00 AM.
