Support email refusing .name TLD

so uh... I tried to submit autosupout from my usual email address (which I have registered with mikrotik including past support tickets, CHR license etc...). But now they seem to refuse .name TLD:

554 5.7.1 : Sender address rejected: Mail from .name not accepted

This is rather annoying. I don't want to have my tickets scattered across different accounts and different email addresses. Is it really necessary to block entire TLD?

Thanks! clearly I failed to search before posting. I will delete this topic and join existing thread.

Closing this thread as there is already one: Problem with sending to support@
