Kolab Roundcubemail smtp error 454

[Gerd Stier]

Hi leute,

ich bin mal wieder am verzweifeln. Hab mich jetzt noch mal dran gesetzt 
und Kolab 3 unter debian nach der Anleitung von hier 
(http://kolab.org/blog/tobru/2013/03/19/kolab-3-debian-wheezy) neu 
aufgesetzt.
Ich konnte mich ohne Probleme anmelden.
Nach einem kleinen FIX konnte ich auch die Benutzer anlegen.

Leider kann ich keine eMails verschicken. Weder nach intern noch nach 
extern.
Ich bekomme immer folgende Fehlermeldung: SMTP Fehler (454): Die 
Authentisierung ist fehlgeschlagen.

Was geht da schief?

Wo kann ich den "SMTP-"Smarthost/Relayhost" einstellen? Beim Kolab 2.4 
war das ganz einfach.
