[Dovecot] Problem with default_mail_env in beta9

[Andreas Schulze]

Hallo,

I am playing arround with dovecot
I hat version 1.0.beta7 running fine. After installing beta9 there is a problem with default_mail_env setting.

I have all users in ldap.
there is an attribute "mailMessageStore" which contains a relative path to users maildir
mailMessageStore: sca/

my mailer completes this relative pathinformation to /var/mail/sca/

therefor I setup default_mail_env to "maildir:/var/mail/%h"
dovecot-ldap.conf includes "user_attrs = mailMessageStore=home,uidNumber=uid,gidNumber=gid"

all fine in beta7

in beta9
I got this in my log:

dovecot: Jun 16 14:50:30 Error: child 30407 (pop3) returned error 89

If I change user_attrs to "user_attrs = mailMessageStore=FOO,uidNumber=uid,gidNumber=gid"
I got
dovecot: Jun 16 14:54:36 Info: Dovecot v1.0.beta9 starting up

this inicates to me, that
 1. homedirvariable is unset
    OK, because I assigned mailMessageStore to local FOO
 2. default_mail_env is correct evaluated to maildir:/var/mail/%h


Question:
Why is default_mail_env not correct evalueted to maildir:/var/mail/sca/ if sca/ is set as homedir ?

As mentions above, this worked fine with beta7 ...

What do I wrong ???
My I provide more Informations ?
