How to set up SMTP email on your MU Online server
Configure email sending (password recovery, account activation) from your MU server's website via SMTP.
SMTP is what lets your server's website send emails — essential for password recovery and account activation. Setup is simple.
What you need
- A sending email (ideally from the server's domain);
- The SMTP host, the port and the security type (SSL/TLS);
- The email's username and password.
SMTP_HOST = smtp.yourdomain.com
SMTP_PORT = 587
SMTP_USER = [email protected]
SMTP_PASS = ********
SMTP_SECURE = tlsNota: Most MU server panels (web systems) have an SMTP configuration area. Just fill in this data.
Step by step
- Create/choose the sending email;
- Get the SMTP data from your email/hosting provider;
- Fill in host, port, username, password and security in the panel;
- Send a test email (password recovery) to validate.
Atenção: Never leave the SMTP password exposed in web-accessible files. Store it in protected configuration.
Dica: If emails go to spam, configure the domain's SPF and DKIM records. This greatly improves delivery.
Perguntas frequentes
What is SMTP for on the server?
SMTP sends the site's emails: password recovery, account activation and notices. Without it configured, those emails won't go out.
Can I use a common email for SMTP?
Yes, as long as the provider allows authenticated SMTP sending. Many use an email from the server's own domain for more trust.
