Sadly, it's been announced yesterday that the nginx.org mailing lists are being shutdown by end of month (Sept 2025).

P.S. Probably one more reason to look into into the freenginx fork of nginx — https://news.ycombinator.com/item?id=39373327 — their mailing lists are at http://freenginx.org/en/support.html.
