How to add company designation in mail sent from c

When sending an email from a C program, you can add a company designation or a signature to the email using the following methods:

Method 1: Using the mail command

You can use the mail command to send an email from your C program. To add a company designation, you can use the -s option followed by the subject of the email, and then add the company designation as part of the subject.

Here's an example:

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

int main() {
    system("mail -s 'From: [Your Name] [Your Company] <[email protected]>' [email protected]");
    return 0;
}

In this example, the company designation is added as part of the subject line.

Method 2: Using a library like libmail

You can use a library like libmail to send emails from your C program. This library provides a more flexible way to send emails and allows you to add a company designation as part of the email body.

Here's an example:

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

int main() {
    Mail *mail = mail_new();
    mail_set_from(mail, "[email protected]");
    mail_set_subject(mail, "Test email");
    mail_set_body(mail, "Hello,\n\nThis is a test email from [Your Company].");
    mail_set_signature(mail, "Best regards,\n[Your Name]\n[Your Company]");
    mail_send(mail, "[email protected]");
    mail_free(mail);
    return 0;
}

In this example, the company designation is added as part of the email body using the mail_set_signature function.

Method 3: Using a library like libcurl

You can use a library like libcurl to send emails from your C program. This library provides a more flexible way to send emails and allows you to add a company designation as part of the email body.

Here's an example:

#include <stdio.h>
#include <stdlib.h>
#include <curl/curl.h>

int main() {
    CURL *curl;
    CURLcode res;
    char *data = "From: [Your Name] [Your Company] <[email protected]>\r\n"
                  "Subject: Test email\r\n"
                  "MIME-Version: 1.0\r\n"
                  "Content-Type: text/plain; charset=UTF-8\r\n"
                  "Content-Transfer-Encoding: 7bit\r\n"
                  "\r\n"
                  "Hello,\r\n"
                  "\r\n"
                  "This is a test email from [Your Company].\r\n"
                  "Best regards,\r\n"
                  "[Your Name]\r\n"
                  "[Your Company]";
    curl_global_init(CURL_GLOBAL_DEFAULT);
    curl = curl_easy_init();
    if(curl) {
        curl_easy_setopt(curl, CURLOPT_URL, "smtp://smtp.example.com");
        curl_easy_setopt(curl, CURLOPT_MAIL_FROM, "[email protected]");
        curl_easy_setopt(curl, CURLOPT_MAIL_RCPT, "[email protected]");
        curl_easy_setopt(curl, CURLOPT_READDATA, data);
        curl_easy_setopt(curl, CURLOPT_READFUNCTION, NULL);
        res = curl_easy_perform(curl);
        if(res!= CURLE_OK) {
            fprintf(stderr, "cURL error: %s\n", curl_easy_strerror(res));
        }
        curl_easy_cleanup(curl);
    }
    curl_global_cleanup();
    return 0;
}

In this example, the company designation is added as part of the email body using the data variable.

Note that these examples are just a starting point, and you may need to modify them to fit your specific use case. Additionally, you should ensure that you have the necessary permissions and credentials to send emails from your C program.
