You’re mail server tried to sent too many mails to Snapmaker, so it got rate limited. That will probably resolve itself after some time, until then you could try using a different e-mail provider.
Thanks for the help
Is “resolution” likely to be days or weeks?..
Ive been trying since the weekend
If you follow the link (and use some translating service) you see that the longest limit should be one day. That’s assuming that you don’t try to send any new mail in the meantime. (Where you actually means anyone using your mail server, if it’s your own server that should be doable, for a public mail system that might never happen)
550 is considered a permanent error, so your email server will discard the message and not try again automatically.
IP Frequency Limited is an odd error for you to get though. It implies that you (or somebody on your email service) is spamming them, and they’re trying to prevent it. Who is your email provider? How many emails did you send?
This is actually a pretty common problem with qq’s mailservers. qq ip frequency limited - Google Search
Snapmaker needs to reach out to zendesk or their mail provider. Send them an email to let them know 
Yea, no phone number is there. I guess there’s the web form on the website that’s kinda hard to use.
It is taking me a bit of time to understand the problem so I will contact my ISP and pass on all your suggestions - thanks
