Hi Hequn, Thanks for reporting this case.
The reason replied by QQ mail team is also caused by *bounce attack*. So this mail address has been intercepted and it's an IP level interception. Today, the QQ mail team has unblocked this email address. So it can receive the follow-up email from Apache mail server normally. If this email address still can not work normally in the future. Please report it here again.
