Send emails from any programming language or application using standard SMTP. This guide covers connection settings, credential creation, and code examples.

SMTP Settings

Creating SMTP Credentials

1. Log into your Email Dashboard
2. Go to SMTP Credentials
3. Click Create Credential
4. Give it a name (e.g., “My App”) and click Generate
5. Copy the username and password — the password is only shown once!

Code Examples

Python (smtplib)

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

msg = MIMEMultipart('alternative')
msg['From'] = '[email protected]'
msg['To'] = '[email protected]'
msg['Subject'] = 'Hello from CyberPanel'

text = 'Hello! This is a plain text version.'
html = '<h1>Hello!</h1><p>This is the HTML version.</p>'

msg.attach(MIMEText(text, 'plain'))
msg.attach(MIMEText(html, 'html'))

with smtplib.SMTP('mail.cyberpersons.com', 587) as server:
    server.starttls()
    server.login('smtp_YOUR_USERNAME', 'YOUR_PASSWORD')
    server.sendmail(msg['From'], [msg['To']], msg.as_string())

PHP (PHPMailer)

use PHPMailer\PHPMailer\PHPMailer;

$mail = new PHPMailer(true);
$mail->isSMTP();
$mail->Host       = 'mail.cyberpersons.com';
$mail->SMTPAuth   = true;
$mail->Username   = 'smtp_YOUR_USERNAME';
$mail->Password   = 'YOUR_PASSWORD';
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
$mail->Port       = 587;

$mail->setFrom('[email protected]', 'Your Name');
$mail->addAddress('[email protected]');
$mail->Subject = 'Hello from CyberPanel';
$mail->isHTML(true);
$mail->Body = '<h1>Hello!</h1>';
$mail->AltBody = 'Hello!';

$mail->send();

Node.js (Nodemailer)

const nodemailer = require('nodemailer');

const transporter = nodemailer.createTransport({
  host: 'mail.cyberpersons.com',
  port: 587,
  secure: false, // STARTTLS
  auth: {
    user: 'smtp_YOUR_USERNAME',
    pass: 'YOUR_PASSWORD',
  },
});

await transporter.sendMail({
  from: '[email protected]',
  to: '[email protected]',
  subject: 'Hello from CyberPanel',
  text: 'Hello!',
  html: '<h1>Hello!</h1>',
});

WordPress (WP Mail SMTP Plugin)

1. Install and activate the WP Mail SMTP plugin
2. Go to WP Mail SMTP → Settings

4. Enter:
   • SMTP Host: mail.cyberpersons.com
   • Encryption: TLS
