Secure email settings for modern clients:
- IMAP: 993 with SSL/TLS
- POP3: 995 with SSL/TLS
- SMTP: 465 or 587 with SSL/TLS or STARTTLS
Username = full email address. Server hostname = value from your welcome email or cPanel Connect Devices.
Do not prefer ports 110, 143, or 25 for new setups — many ISPs block outbound 25, and cleartext is obsolete.
