If your email client cannot send messages using SMTP, the issue is usually one of: wrong server name, wrong port/encryption, missing authentication, or an incorrect password.
Correct SMTP settings for GARMTECH Business Email
- Outgoing server (SMTP): your service server hostname (shown in My.GARMTECH for your email/hosting service)
- Port:
465
- Encryption: SSL/TLS
- Authentication: required (username and password)
- Username: full email address (example:
user@example.com)
Step-by-step checklist
- Verify the password:
- Try logging in to GARMTECH.Email (web interface). If login fails there, reset the password first.
- Check the server hostname:
- For secure SSL connection, use the server hostname from My.GARMTECH (not
mail.yourdomain.com unless you configured it specifically).
- Check port and encryption:
- SMTP must be 465 with SSL/TLS (not port 25).
- Enable SMTP authentication:
- Outgoing server must use the same username/password as the mailbox.
- Try another network:
- Some networks restrict outgoing mail ports. Test via mobile hotspot or a different Wi‑Fi.
Typical error messages and meaning
- “Authentication failed” / “Invalid login”: wrong password or wrong username format (must be full email address).
- “Cannot connect to server” / timeout: wrong hostname, blocked network, or wrong port/encryption.
- “Relay access denied”: SMTP authentication is disabled in the mail client.
Tip: If you recently changed DNS or moved your domain, verify that you still use the correct server hostname for SMTP and that the mailbox exists in the correct service.
