[Dovecot] LDA, postfix and multiple virtual users : postfix is still the MDA

[Antoine Souques]

Hi,

I have some trouble to use dovecot as MDA. I followed the instructions 
in http://wiki.dovecot.org/LDA and http://wiki.dovecot.org/LDA/Postfix

I have multiple virtual users, stored in a LDAP server, and it look like 
postfix is still delivering the mails directly to the maildirs.

Dovecot version : 1.2.15 (using the 1:1.2.15-4 squeeze packets)
postfix version :  2.7.1 (using the 2.7.1-1 squeeze packet)

During the mail delivery, I doesn't have any log from dovecot, and i 
didn't have set the bit_suid/sudo, so the deliver process can't deliver 
the mail to the maildir.

Have someone any idea about what i did wrong ?
