-------------------------------------
[~simonalexs] I'm one of the moderator of calcite dev mailing list, there is
one strange email in the list (no sender, no content), I'm not sure if it's
related.
AFFAIK, you can send to the dev mailing list even without subscribing to it.
I'm not sure what's happening, maybe you can try again, fails that, maybe you
can try another email client.
