Use these values for any mail client. Replace you@yourdomain.com with the real address.
- Incoming (IMAP) — server:
mail.yourdomain.com, port993, SSL/TLS on. - Outgoing (SMTP) — server:
mail.yourdomain.com, port465with SSL (or587with STARTTLS), authentication on, same username and password. - Username — always the full email address.
If Outlook refuses to connect while other clients work, port 25 is likely blocked by your internet provider; use 465 instead. For sending problems, confirm SMTP Restrictions is not blocking the script or device in cPanel.
