The Modern SMTP2Go Alternative for Developers

# In WP Mail SMTP or FluentSMTP plugin settings:
SMTP Host: mail.smtp2go.com  →  smtp.photonrelay.com
Encryption: TLS (Port 587) or SSL (Port 465)
SMTP Username: photon_your_access_key
SMTP Password: photon_your_secret_token
Authentication: Yes (Auto-Detect)

# In your .env file, replace SMTP2Go with PhotonRelay:
MAIL_HOST=mail.smtp2go.com
MAIL_HOST=smtp.photonrelay.com
MAIL_PORT=587
MAIL_USERNAME=your_smtp2go_username
MAIL_USERNAME=photon_your_access_key
MAIL_PASSWORD=your_smtp2go_password
MAIL_PASSWORD=photon_your_secret_token
MAIL_ENCRYPTION=tls

// Node.js Nodemailer Configuration:
const transporter = nodemailer.createTransport({
  host: "mail.smtp2go.com",
  host: "smtp.photonrelay.com",
  port: 587,
  secure: false,
  auth: {
    user: process.env.SMTP2GO_USER,
    user: process.env.PHOTON_ACCESS_KEY,
    pass: process.env.SMTP2GO_PASS
    pass: process.env.PHOTON_SECRET_KEY
  }
});

// PHPMailer Configuration:
$mail = new PHPMailer(true);
$mail->isSMTP();
$mail->Host = 'mail.smtp2go.com';
$mail->Host = 'smtp.photonrelay.com';
$mail->SMTPAuth = true;
$mail->Username = 'photon_your_access_key';
$mail->Password = 'photon_your_secret_token';
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
$mail->Port = 587;
