        # The proxy REQUIRES STARTTLS before it will accept AUTH, so clients must
        # reach it by a name the certificate actually covers. The wildcard is
        # *.gbrown.org, which matches ONE label -- hence smtp-usesend, not
        # smtp.usesend.
        #
        # Resolution: podman's aardvark-dns answers this name authoritatively for
        # containers ON nginx-bridge, handing back the container IP. NPM is not
        # involved at all -- it only reverse-proxies HTTP(S), and SMTP ports are
        # never published to the host, so the proxy is unreachable from outside.
        #
        # NOTE: there IS a wildcard *.gbrown.org record in Cloudflare, so this name
        # also resolves publicly (to Cloudflare, which serves nothing for it). The
        # consequence: if this container is STOPPED, aardvark-dns stops answering,
        # the lookup falls through to that public record, and clients dial
        # Cloudflare on 587 and hang until timeout instead of failing fast.

        # name UseSend's own UI advertises and is the target to standardise on;
        # smtp-usesend stays until every consumer has been moved across.

    # The `Home` wg interface sits in firewalld's `trusted` zone, so no rule is needed.
    # Rootless can bind these because net.ipv4.ip_unprivileged_port_start = 80.
