Kolab3 multi-domain

[mailingliste at dreampixel.de]

Hi at all,

I have install kolab3 on a centos 6.3 and setup it for my primary  
maildomain (gehr-edv.de). The mail system works (send / receive). Now  
however, I need a second mail domain (dreampixel.de).

I added this second domain in the kolab-webinterface. Then I edited  
the following files:


<< /etc/postfix/sasl_passwd >>

[mail.gehr-edv.de] office at gehr-edv.de:xxxxxxxxxx
[mail.dreampixel.de] office at dreampixel.de:xxxxxxxxxx


<< /etc/postfix/main.cf >>

[...]
# Postfix Relay Host
relayhost = [mail.gehr-edv.de]
smtp_use_tls = no
smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd


run 'postmap /etc/postfix/sasl_passwd'


I add the mailadress (for example) 'mailinglist at dreampixel.de' in the  
webmailer (settings/identity). Whe I try to send a mail with this  
identity I get the error:

SMTP Fehler: [554] 5.7.1 <DATA>: Data command rejected: Could not find  
envelope sender user mailingliste at dreampixel.de

what's wrong?

best regards
sven
