BTW: You use eternal-september.org - did you ever read their terms of use?

<http://www.eternal-september.org/index.php?showpage=terms>

Quote:

Users of the news server news.eternal-september.org are obliged to abide
by the following rules. Failure to do so will cause immediate
termination of access rights without prior notice.

* Sender Address

  The e-mail addresses given in "From:", "Reply-To:", and "Sender:"
  SHOULD be yours (i.e. you should be entitled to use it) and SHOULD be
  valid (= should not bounce because of invalidity). Using addresses
  and name space of other people without their consent is prohibited.

(unquote)

So - to use the services of eternal-september.org it is *required* to
use a valid sender address or the TLD ".invalid" according to RFC5537 by
2009(!) (<http://www.rfc-editor.org/rfc/rfc5537.txt>) which replaced
RFC1036 and SON-OF-RFC1036.

You may not like these rules. But this does not mean, you can just
ignore them by using an invalid address and call other people "pedantic
trolls" and "sick".
