[Dovecot] Dovecot upgrade 1 to 2 on Debian Squeeze : broken /var/run/dovecot

[Si L]

Hi,

 I just upgraded from version 1 to version on Debian Squeeze using their backports.

Like I expected my dovecot1 config had to be converted using doveconf and this I did.

However, I see problems with files inside directory:
drwxr-xr-x 4 dovenull root 4096 Feb 25 20:35 /var/run/dovecot

All of them were created owned by root:root rw.

I tried to changed, for example :
chown postfix:dovecot /var/run/dovecot/auth-master
but noticed when I restarted dovecot it reset the permissions back to root:root rw.

Here's the version:
# dovecot --version
2.1.7

Here's my slightly redacted conf.
# grep -v ^# dovecot.conf|grep -v ^$
auth_mechanisms = plain login
auth_verbose = yes
dict {
  quotadict = mysql:/etc/dovecot/dovecot-dict-quota.conf
}

  driver = sql
}
plugin {
  quota_rule = *:storage=262144:messages=20000
  quota_rule2 = Trash:storage=282144:messages=23000
}
service auth {
  unix_listener /var/spool/postfix/private/auth {
    group = postfix
    mode = 0660
    user = postfix
  }
  unix_listener auth-master {
    mode = 0600
    user = vmail
  }
  user = root
}
service imap-login {
  chroot = login
  inet_listener imap {
    address = 127.0.0.1
    port = 3993
  }
  inet_listener imaps {
    address = *
    port = 993
  }
  process_limit = 256
  process_min_avail = 24
  service_count = 1
  vsz_limit = 48 M
}
service pop3-login {

}
protocol lda {
  auth_socket_path = /var/run/dovecot/auth-master
  log_path =

  postmaster_address = xxxx at xxxxx
}


I really don't understand how I should make this work, and the after I read the docs on dovecot.org and googled I realised I was really lost getting this back up and runing :(

I should be really grateful if somebody would give me some advice.

Thanks, 
Soph'
