I thought I did. Mine is @thomas-bkk.my-fqdn.de. Search Google News
and you'll find my postings.

This goes back to http://einklich.net/usenet/netscape.htm (sorry to
the others, it's in German) and to flames I got on the usenet using
GMX mids in the beginning.

OK, let's talk about RFCs. There was one (pertaining to the usenet
only) saying that you need to own the domain if you want to create
mids from it. I'll search for that RFC, but maybe you're faster.

Tell that to Volker Gringmuth (a guru on the de.* hierarchy of the
usenet).

PP> You should do your best to ensure, but how can you *make sure* it is

Exactly.

See above.

You misunderstand. News postings get propagated across servers, ML
postings don't.

TF>> I am not sure that 192.x.x.x qualifies as an FQDN.

PP> No, because it ain't neither a *name* nor a *domain name*, not to

ACK.

PP> But that's not the point.

Aha.

PP> No RFC says you *have* to use the FQDN,

This is the point I'll have to prove to you.

True. Are you on the de.* hierarchy of the usenet?

I don't take this personally, don't worry. We are discussing an issue,
and I need to find that RFC Volker G. refers to.
