Asi proto že to máš nastavené

Takže to zruš.

6.2.5.2.1 Základné nastavenia Vášho mailového servera

Skontrolujte si nastavení append_at_myorigin, append_dot_mydomain, masquerade_domains.

[anon123]

To je mi jasny, ze to bude nekde v nastaveni . Ale ja jsem to nenastavoval, ale ten kdo se o to stara je na dlouho na dovolene.

Prosel jsem ten configurak, take jsem par veci zkousel menit, ale nemuzu najit nic spatneho. Muzes se na to mrknout?

Aha prehlidl jsem to masquerade_domains = sceggs.nsw.edu.au students.sceggs.nsw.edu.au

Takze to masquerade musim odstranit, ze? Kdyz jsem to udelal, tak domena mailu nebyla zmenena. Doufam, ze to nerozbije neco jineho. Nevim jestli to tam bylo zamerne, kvuli necemu.

[Petr Šobáň]

Já taky těžko můžu vědět proč to tam bylo to musíte vědět vy jaké máte emailové adresy a jaké server přijímá a proč to měníte, nebo neměníte.

Proč se nekouknete do toho návodu co jsem dal odkaz.

masquerade_domains = $mydomain

zoznam domén, z ktorých má byť pri posielaní mailov cez Váš server odstránená subdoménová časť z hlavičiek (napr. ak je mydomain = "sub.example.com", vznikne "example.com"). Ak použijete tento parameter, musíte samozrejme zabezpečiť príjem/preposlanie mailov aj pre používateľov, ktorým ste takto skrátili adresy.

[anon123]

Ja jsem se tam koukal a pochopil jsem, take jsem tak upravil (zakomentoval) a vse fungovalo.

Jen jsem chtel rici, ze doufam, ze vse ostatni bude v poho, protoze to spravuje nekdo jiny (je na dovolene) a nevim, jaky byl jeho zamer. Tot vse. Jinak diky za link.
