Creating new topics by email does not work for me

I'm trying to announce new plugins using STMP and my messages don't appear. So I add them manually.

Is there anything wrong?

Here is what I'm sending:

Sending to discuss+announcements@elastic.co from david@pilato.fr using smtp.free.fr.

Sometimes it was working. Not every time.
No I never got a failure message back.

This should be working now consistently. see:
