SMTP port for sending email
Learn which SMTP ports you can use to send email and which one is best for your account.
Introduction
If you can receive email but not send it, the problem is often the SMTP server, the selected port, the encryption type or authentication.
Common SMTP ports
| Port | Use | Recommendation |
|---|---|---|
25 | Traditional SMTP | Not recommended for mail clients |
26 | Older alternative to 25 | Last resort only |
465 | SMTP with SSL/TLS | Recommended if your client supports it |
587 | SMTP with STARTTLS | Recommended modern option |
2525 | Alternative in some environments | Only if specifically required |
For miHosting accounts, prioritize 465 with SSL/TLS or 587 with STARTTLS.
Recommended settings
| Item | Value |

| Port | 465 or 587 |
| Security | SSL/TLS for 465, STARTTLS for 587 |

Conclusion
To send email securely, configure SMTP with mail.yourdomain.com, authentication enabled and port 465 or 587. If sending still fails, review the exact error before changing more settings.
