6. Best Practices
- Use App Passwords when available — never your real login password.
- Always use secure ports (
465/993) with SSL. - Avoid shared or root email credentials.
- For hosted domains, create dedicated mailbox users for Kurrier.
Tip: You can create multiple SMTP/IMAP accounts in Kurrier — one for each mailbox or domain you manage.
