550 Ip frequency limited

  • Answered

When we send e-mails to domain tongshang.com, we get a hard bounce 550 Ip frequency limited

I have searched the issue and it is apparently something that happens with QQ mail servers. They have the following to say.
550 Ip frequency limited
The reason for the error : the server IP transmission frequency exceeds Tencent mailbox limit.

Tencent mailbox from the same IP external server has a certain frequency limit:
1, more than every minute traffic limit, this IP address is forbidden to send a few minutes.
2, more than the hourly traffic limit, this IP address is forbidden to send a few hours.
3, more than the daily traffic limit, this IP address within this day to prohibit the re-letter.
4, the above frequency limit value belongs to Tencent mailbox confidential data, is not open.

IMPROVED RECOMMENDED : If you are an administrator of the server IP, pause the server IP's write, and then lower the frequency to retry the message.
If you are a personal email user, please report this to your email provider.

Please note. I am able to send e-mail to this domain using a GMail account. Can you help?
