[ERLEDIGT]Problem Outlook2010 und Postausgangsserver

[doh]

Hallo zusammen!

Mit Thunderbird, OutlookExpress etc. lassen sich wunderbar Emails versenden und auch erhalten (wie gewohnt). Letzten Freitag richtete ich bei meinem Cousin sein Outlook2010 ein und siehe da, ich konnte bzw. ich kann nur Emails empfangen, aber NICHT versenden (Outlook-Fehlercode: 0x800CCC0F : Die Serververbindung wurde unterbrochen...).

Mein ispCP: 1.0.0 OMEGA (build: 20090225)

Meine main.cf (/etc/postfix)

Jan 17 14:45:27 server postfix/master[25510]: warning: process /usr/lib/postfix/smtpd pid 8665 killed by signal 11

Scheinbare Lösung (sagte Google):
/etc/postfix/sasl.conf bearbeiten und dort den Eintrag "ntlm" hinter "mech_list:" entfernen, danach Postfix neustarten.
(http://forum.collax.com/viewtopic.php?f=3&t=6094)

Habs aber noch nicht getestet, weiß auch noch nicht genau wo?!
Da ich mich in Richtung Postfix kaum auskenne wollte ich a) die "Lösung" absegnen lassen, ob das so i.O. ist (Nachteile dadurch??) und b) die Sache als Bugreport melden, falls sie nicht schon längst beseitigt wurde (bin ja einige Versionen hinten dran)

Danke im Voraus für eure Antworten!
