[Dovecot] Dovecot LDA/LDAP

[Frank den Hartog]

  I'm a total newbie with Dovecot LDA and LDAP. To be honoust, I don't 
know what I'm doing.

My system runs CentOS 5.5, Postfix 2.3.3 and Dovecot 1.2.11. I try to 
set up Dovecot LDA. But whatever I'm trying, I fail.

2010-06-30T18:28:12.585128+02:00 h1690641 postfix/pipe[26443]: 
84F012A00A55: to=<test at domain.com>, relay=dovecot, delay=0.07, 
delays=0.03/0.01/0/0.02, dsn=5.1.1, status=bounced (user unknown)

My current situation:

I'm using at the current server OpenLDAP, Postfix and Dovecot with the 
Postfix LDA. It works fine, but I want to use sieve. I've setup a second 
server. I'm using my current OpenLDAP directory.

The configurations:

I've used http://www.linuxmail.info as an example. That works fine, but 
I want more.
