1. Introduction
A contact form is essential for most websites, allowing visitors to communicate with the site owner without revealing email addresses. Proper SMTP configuration ensures that messages sent via the contact form are delivered reliably to your inbox.
In this guide, we will explain the general process of configuring contact forms using Domain India’s hosting service. We’ll cover creating an email account, configuring SMTP, and integrating it into your contact form using a sample code that works across any hosting environment.
2. Understanding SMTP for Contact Forms
What is SMTP?
SMTP (Simple Mail Transfer Protocol) is a protocol used to send emails. It ensures that messages are sent from your server to the recipient's email address securely and reliably.
Why Use SMTP for Sending Emails from Contact Forms?
Using SMTP for your contact forms improves email deliverability and reduces the chances of emails being marked as spam. SMTP authenticates the email-sending process, making it secure and reliable.
Common SMTP Settings in Domain India Hosting
To configure SMTP for your contact form, you’ll need the following information:
- SMTP Host:
mail.yourdomain.com(replaceyourdomain.comwith your domain) - SMTP Port: 587 (for TLS encryption) or 465 (for SSL encryption)
- SMTP Username: Your email account (e.g.,
contact@yourdomain.com) - SMTP Password: The password for your email account
- Encryption: TLS or SSL, depending on the port used
3. Creating an Email Account in Domain India Hosting
To send emails from your contact form, you need an email account configured on your hosting server. Here’s how to generally create an email account across different hosting environments:
- Log in to your hosting control panel.
- Navigate to the Email Accounts section.
- Click Create Account.
- Enter the email address you want to use (e.g.,
contact@yourdomain.com). - Set a password and assign mailbox storage (optional).
- Click Create to finalize the setup.
This newly created email account will be used to authenticate your SMTP connection for sending emails via the contact form.
4. SMTP Configuration for Contact Forms
Now that you’ve created an email account, the next step is to configure your contact form to send emails via SMTP. Below are the general steps to configure SMTP for your contact form:
SMTP Settings
- SMTP Host:
mail.yourdomain.com - SMTP Port: 587 (for TLS) or 465 (for SSL)
- SMTP Username:
contact@yourdomain.com - SMTP Password: The password you created for the email account
- Encryption: TLS or SSL, based on your selected port
Sample Code for Contact Form Using PHPMailer
Below is a sample PHP script using PHPMailer to configure your contact form and send emails via SMTP.
<?php
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
require 'PHPMailer/src/Exception.php';
require 'PHPMailer/src/PHPMailer.php';
require 'PHPMailer/src/SMTP.php';
$mail = new PHPMailer(true);
try {
//Server settings
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = 'mail.yourdomain.com'; // Specify SMTP server
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = 'contact@yourdomain.com'; // SMTP username
$mail->Password = 'your_password'; // SMTP password
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; // Enable TLS encryption
$mail->Port = 587; // TCP port
//Recipients
$mail->setFrom('contact@yourdomain.com', 'Your Website');
$mail->addAddress('recipient@example.com'); // Add a recipient
//Content
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'New Contact Form Submission';
$mail->Body = 'This is the message body...';
$mail->send();
echo 'Message has been sent';
} catch (Exception $e) {
echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
This sample code demonstrates how to send emails via your Domain India hosting server’s SMTP service. You need to adjust the SMTP Host, Username, and Password based on the email account you created.

Testing the Contact Form
After configuring the contact form, test it by submitting a sample message and checking if the email is delivered successfully.
5. Troubleshooting Common Contact Form Issues
Emails Not Sending
- Ensure that the SMTP server settings (host, port, encryption) are correct.
- Verify the email account username and password for authentication.
SMTP Authentication Errors
- Ensure that the correct email account credentials are used in the contact form configuration.
- Double-check the port number and encryption type (TLS/SSL).
Form Validation Issues
- Make sure that all required form fields are properly validated before submission to avoid empty or invalid inputs.
SPF, DKIM, and DMARC Configuration
- Ensure that the appropriate DNS records (SPF, DKIM, and DMARC) are correctly configured to improve email deliverability and avoid messages being marked as spam.
6. Security Best Practices for Contact Forms
Use SSL/TLS Encryption
Always use SSL/TLS to secure the email communication between your server and the email client to prevent unauthorized access.
Avoid Open Relays
Ensure that your SMTP server is properly secured to avoid being used as an open relay for spam. Always authenticate your SMTP connections.
Validate User Inputs
Make sure all input fields in your contact form are validated to prevent malicious submissions and spam bots from abusing the form.
7. Advanced Features for Contact Forms
Adding File Attachments
PHPMailer allows you to add attachments to emails sent from your contact form. To do so, use the following line within the PHPMailer configuration:
$mail->addAttachment('/path/to/file.pdf', 'FileName.pdf');
Integrating CAPTCHA
Integrate CAPTCHA (such as Google reCAPTCHA) to your contact form to reduce spam submissions. It ensures that only human users can submit the form.
Customizing Contact Form Fields
You can easily customize the fields in your contact form, such as adding fields for a phone number, subject, or department.
8. Conclusion
