I did not subscribe the gmane account when I tried out posting via
gmane.

I am pretty sure that I already subscribed to the group in the past.
Nevertheless, I subscribed again (via e-mail). I got a validation e-mail
that I confirmed but posting to the list still does result in no message
appearing in the list. No error mail came back either.
