Ah yes.
But later i sent a follow-up to the message to which Rodolfo's replies
don't make it through the Debian list server.

It looks barely legal. "lenovo" as domain is not very unique.
Normally it should be a registered domain name, so that no machine outside
that domain feels entitled to use its name in unique identifiers.

I doubt that Andrei's system(s) have anything to do with the problem.
The decision not to forward your mails is done by the Debian server,
unless your mail provider silently failed to hand over the mail to that
server.


I have a new theory.
The (to my knowledge) last failed attempt has:

One header is missing:

  To: ...

According to RFC5322, the header To: is optional.
But not having it is really unusual.
Then there is the Newsgroups: header. This belongs to USENET, not to e-mail.


I think i cannot keep my mail sender from adding a To: header.
Will have to hack it for an experiment.


Have a nice day :)
