Mailing-list emails not making it into Forum

[MichaelAtOz]

OpenSCAD Forum.
The linked Mailing-list is working.
New Forum posts get sent to the Mailing-list, but don't get received back, and hence no Forum post actually happen.
Mailing-List emails are not getting posted to the Forum.
I've checked the [e-mail] address it looks good.
I haven't changed anything.

I have a vague recollection this happened before, the Nabble mail daemon was down (or stuck).
On restart the backlog were eventually processed.
Could you check please.

(I also checked the blacklists, seems OK)

Note this is different to the previous topic/problem.
In it Forum posts never made it to the Mailing-list, and Mailing-list emails were posted to the forum.
This time Forum posts DO make it to the Mailing-list, and Mailing-list email are NOT posted to the Forum.

So Nabble is posting to [e-mail] OK.
[e-mail] forwards it to all list subscribes, including [e-mail].
But Nabble is not reacting to incoming emails, either from Forum posts or emails to the list.

I presume someone kicked the server, it's working now.
