Store credentials in `.env` (add to `.gitignore`) - For Gmail: use App Password if 2FA is enabled - For 163.com: use authorization code (授权码), not account password ## Troubleshooting **Connection timeout:** - Verify server is running and accessible - Check host/port configuration **Authentication failed:** - Verify username (usually full email address) - Check password is correct - For 163.com: use authorization code, not account password - For Gmail: use App Password if 2FA enabled **TLS/SSL errors:** - Match `IMAP_TLS`/`SMTP_SECURE` setting to server requirements - For self-signed certs: set `IMAP_REJECT_UNAUTHORIZED=false` or `SMTP_REJECT_UNAUTHORIZED=false`
