Outbound SMTP Code Examples

use PHPMailer\PHPMailer\PHPMailer; $mail = new PHPMailer(true); $mail->isSMTP(); $mail->Host = 'api.smtp.mom'; $mail->SMTPAuth = true; $mail->Username = 'YOUR_MOM_SMTP_USER'; // e.g. mom_a1b2c3d4e5 $mail->Password = 'YOUR_MOM_SMTP_KEY'; // your secure API password key $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; $mail->Port = 2525; // Or 587 $mail->setFrom('[email protected]', 'Mailer'); $mail->addAddress('[email protected]'); $mail->Subject = 'Test Email via SMTP.MOM'; $mail->Body = 'High speed email delivery connection verified!'; $mail->send();
// Add this snippet to your active theme's functions.php file add_action('phpmailer_init', 'smtp_mom_wp_config'); function smtp_mom_wp_config($phpmailer) { $phpmailer->isSMTP(); $phpmailer->Host = 'api.smtp.mom'; $phpmailer->SMTPAuth = true; $phpmailer->Port = 2525; // Or 587 $phpmailer->Username = 'YOUR_MOM_SMTP_USER'; $phpmailer->Password = 'YOUR_MOM_SMTP_KEY'; $phpmailer->SMTPSecure = 'tls'; }
const nodemailer = require('nodemailer'); const transporter = nodemailer.createTransport({ host: 'api.smtp.mom', port: 2525, // Or 587 secure: false, // true for 465, false for other ports auth: { user: 'YOUR_MOM_SMTP_USER', pass: 'YOUR_MOM_SMTP_KEY' } }); transporter.sendMail({ from: '"Mailer" ', to: '[email protected]', subject: 'Test Email via SMTP.MOM', text: 'High speed email delivery connection verified!' });
import smtplib from email.mime.text import MIMEText msg = MIMEText('High speed email delivery connection verified!') msg['Subject'] = 'Test Email via SMTP.MOM' msg['From'] = '[email protected]' msg['To'] = '[email protected]' with smtplib.SMTP('api.smtp.mom', 2525) as server: server.starttls() server.login('YOUR_MOM_SMTP_USER', 'YOUR_MOM_SMTP_KEY') server.send_message(msg)
