**问题**：列出今日发出的所有追收保证金通知及其回复状态。

**SQL**：
```sql
-- 查询今日追缴保证金记录 (参考日期: 2026-04-02)

    a.CallForDepositDays AS OverdueDays
FROM MCAccount a
WHERE a.CallForDepositDate = '2026-04-02'
ORDER BY a.CallForDeposit DESC;
```

**说明**：- `MCAccount.CallForDepositDate` = 追缴通知发出日期，`CallForDeposit` = 追缴金额
- `CallForDeposit < 0` 表示已结清；如查活跃追缴，应筛选 `CallForDeposit > 0`
