[Dovecot] Using Dovecot deliver with Postfix

Hello,

while installing Dovecot sieve, I am not able to deliver email for root. The strange thing is, that mails to ordinary users get delivered. And no, I do not use virtual mail, just ordinary unix accounts with an entry to passwd / shadow. Also before switching from Postfix deliver to Dovecot deliver, everything worked fine. Current versions for dovecot and postfix are:

dovecot-1.2.8 postfix-2.6.5

Anybody an idea, where I misconfigured something?

Thanks in advance Tobi

Here is an excerpt from my dovecot.conf:

dovecot.conf:

protocol lda { postmaster_address = postmaster@DOMAIN #mail_plugins = sieve # Disabled to fix deliver issue } mail_location = maildir:%h/Maildir auth default { mechanisms = plain login passdb pam { args = * } userdb passwd { } socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } }
