NetEase Enterprise Mail Setup: Client Authorization Password + IMAP/SMTP (incl. IP Restriction Troubleshooting)
Complete configuration flow for NetEase Enterprise Mail — servers come in 'Recommended + Backup' pairs, you must use the 16-digit Client Authorization Password generated in the web UI (not the login password), and bind a phone number before generating it. Binding errors with ERR.LOGIN.IPDENY mean the admin set an IP whitelist — they need to lift the restriction.
