Problems with comment mailing list?

Dear all,

I'm wondering whether the mailing list public-dxwg-comments@w3.org works well for us.
I just had to forward myself a perfectly legit mail from a colleague, which was blocked. And the number of emails that we got on this list is not high: https://lists.w3.org/Archives/Public/public-dxwg-comments/
Could it be that others were blocked?

Kind regards,

Antoine
