Forum and mailing list not syncing

At least since yesterday some forum posts have not been syncing back to the mailing list.

The latest threads from the English Users forum that did not sync to the mailing list:

Some of these threads date back over 24 hours ago.

Furthermore, some threads started directly on the mailing list are not being synced back to the forum. These include:

And at least one direct email reply to a forum topic was not synced back:

Earlier today, some forum posts were synced from the forum to the mailing list. These include:
http://listas.trisquel.info/pipermail/trisquel-users/2012-February/007081.html
http://listas.trisquel.info/pipermail/trisquel-users/2012-February/007082.html
http://listas.trisquel.info/pipermail/trisquel-users/2012-February/007083.html
http://listas.trisquel.info/pipermail/trisquel-users/2012-February/007084.html

The expected behavior in all thee cases is that the forum and mailing list should have all messages synced, whether created directly on the forum or sent via email.
