-----------------------------------------------
[~simonalexs] no need to be a committer for the ML and I am not aware of any
restrictions regarding email domains (I think I have seen QQ emails used here
in the past).
Apache MLs are moderated and require you to subscribe though (see
[https://calcite.apache.org/community/#mailing-lists|https://calcite.apache.org/community/#mailing-lists]
), your previous email is probably awaiting for manual approval.
If you register you should be able to send and receive emails, if that's not
the case let us know.
