[Eisfair] Mail -> Weiterleitung an übergeordneten Mailserver

[Kulzer, Wilhelm]

Hallo,

Lokale Programme/Skripts können Emails als root an das Mail-Paket (exim) 
senden (root at localhost).

Alle Emails leite ich nun zu einem übergeordneten Mailserver weiter,
wobei ich Sender und Empfänger ersetzen muss.

Absender muss (symbolisch) lauten: srv at domain.com
Empfänger (ebenfalls symbolisch): verteiler at domain.com

Im Ereignislog sehe ich dann folgenden Eintrag einer fehlgeschlagenen 
Weiterleitung (reale Emailadressen angepasst):

- Wieso beendet Exim vorzeitig die Kommunikation?
- Wieso steht im Kommando "MAIL FROM" im AUTH-teil noch die originale 
Adresse?
