app.post('/send', async (req, res) => { // await startSMPTServer(); const { to, subject, text } = req.body; console.log("Sending email ...", req.body); // Replace these details with your actual SMTP server configuration const smtpConfig = { host: 'localhost', // Replace with your SMTP server IP or hostname port: 25, // Replace with your SMTP server port secure: false, tls: { rejectUnauthorized: false, // Accept self-signed certificate during development/testing } };

const transporter = nodemailer.createTransport(smtpConfig);

const mailOptions = { from: 'hamza@geekgenix.com', // Replace with the sender email address to, subject, text, };

try { console.log("Sending email ...", mailOptions); // Send the email using nodemailer and your custom SMTP server await transporter.sendMail(mailOptions); res.json({ message: 'Email sent successfully.' }); } catch (error) { console.error('Failed to send email:', error.message); res.status(500).json({ error: 'Failed to send email.' }); } }); this is my code but i am getting error from your package
