Dotaz: Sendmail - konfigurace

[gaminn]

Celej den sedím u kompu a snažím se nakonfigurovat mailserv (Sendmail - vím, že to není nic pro začátečníka, kterej nikdy se serverem nedělal, ale nemám jinou možnost). Mám problém při odesílání pošty - hlavička e-mailu, který přijde (nebo by měl přijít) je:

Received: (qmail 20044 invoked from network); 16 Jan 2005 14:49:40 +0100
Received: from unknown (HELO localhost.localdomain) (***.***.***.***)
by vega.go.seznam.cz with SMTP; 16 Jan 2005 14:49:40 +0100
Received: from localhost.localdomain (f027 [127.0.0.1])
by localhost.localdomain (8.13.1/8.13.1) with ESMTP id j0GDnKXe002246
for prijemce@seznam.cz; Sun, 16 Jan 2005 14:49:20 +0100
Received: (from nobody@localhost)
by localhost.localdomain (8.13.1/8.13.1/Submit) id j0GDnKSa002245;
Sun, 16 Jan 2005 14:49:20 +0100

Porblém je v tom, že třeba na atlas.cz, centrum.cz e-mail nepřijde, protože ho odmítnou - kvůli hlavičce, která obsahuje neznámého odesílatele - jak udělat, aby se do hlavičky zapisoval správný odesílat (ne jenom nějako localhost.localdomain)?

Problém je v odesílací adrese. Jednak není vhodné asi pracovat pod nobody a jednak je zapotřebí přepisovat domeny. Ukázka příslušné části sendmail.mc, která nahrazuje lokální jmena na tvijedomena.cz

Díky moc, to je přesně to co potřebuju....určitě blbej dotaz, ale udělám to, abych nepracoval pod nobody?

[gaminn]

Tak smůla....nastavil jsem to přesně tak, předělalo to i soubor sendmail.cf, restartoval jsem to...a výsledek je úplně stejný...

[gaminn]

Tohle je konfigurační soubor, co je špatně??? (tady na stránce jo kód zmatlanej dohromady, mrkni do zdrojového kódu této stránky, tam je to zobrazeno dobře)
