Is the mail Server down?

Hi,

I’m trying to send email to the company, but got the following error message.

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of
its recipients. This is a permanent error. The following address(es)
failed:

biz@clockworkpi(dot)com:
SMTP error from remote server for RCPT TO command, host: mxbiz1.qq.com (184.105.206.58) reason: 550 Sender frequency limited.

I’m just wondering that is the mail server down?

Regards

We use a hosted mail service by Tencent, it’s probably too busy at the time, could you please try again at other time, or just send a private message here to me.
