[Dovecot] Using Dovecot deliver with Postfix

[Tobias Lang]

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 at 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
    }
  }
}
