Documentation Troubleshooting
Other email (IMAP) problems
Host, port, app passwords and provider enablement.
- "Cannot reach the server" — check the IMAP host under Advanced settings (imap.yourdomain.com may not exist; check your provider's documentation).
- "Authentication failed" — use an app-specific password, not the account password.
- Zoho: enable IMAP Access in Zoho Mail settings first.
- Port 993 requires SSL; port 143 is unencrypted — prefer 993.
