Fetchnews adds this, and it mentions which are the article numbers (per
group) on the server. The header is
XRef: {servername} {groupname}:{artno} [...]
with as many groupname:artno pairs as the article is available from
locally.
Does your local hostname match that of an upstream? It should not.

No Xref: header will be added to outgoing postings.

No, unfortunately you cannot avoid this. However, if "mydomain.com"
(please use example.com or example.org in your examples, these are
reserved -- mydomain.com belongs to some company in Vancouver, WA, USA)
is routable for mail, you may consider inserting a bogus first component
to make MX and A lookups fail. If you need a replyable domain
internally, use split horizon DNS.
Leafnode, being able to post the same article to multiple servers, has
to generate a Message-ID, to avoid duplicate posts.

That Message-ID is from leafnode - apparently, Thunderbird hasn't
generated a Message-ID, and that's fine, newsreaders do not need to do
this.
