Use IMAP if you want email to stay synced across devices. Use SMTP for sending mail.

• Username: full email address.
• Password: mailbox password.
• Incoming: IMAP with SSL/TLS when available.
• Outgoing: SMTP with authentication enabled.

Server names and ports can vary by domain setup. If automatic setup fails, contact support with the email address, device/app name, and screenshot of the settings screen.
