Postfix dorucovanie prostrednictvom Dovecot lda

[Ciernik Tomas]

Zdravim,

snazim sa vyriesit problem s dorucovanim lokalnej posty prostrednictvom
dovecot lda.
Pri pokuse o dorucenie mi hlasi v logu
Fatal: setgid(20000) failed with euid=993, gid=993, egid=993: Operation not
permitted
20000 = postfix, 993 = dovecot

v dovecot.conf mam:

  socket listen {
    master {
      path = /var/run/dovecot/auth-master
      mode = 0660
      user = postfix
      group = dovecot
    }
  }


main.cf:

virtual_transport = dovecot
dovecot_destination_recipient_limit = 1


master.cf:

dovecot unix    -       n       n       -       -       pipe
  flags=DRhu user=dovecot argv=/usr/local/libexec/dovecot/deliver -f
${sender} -d ${recipient}


Skusal som zmenit parameter user=postfix, vtedy mi pre zmenu hlasi:
fatal: user= command-line attribute specifies mail system owner postfix


Mozte mi niekto poradit ako z toho von? Trapim sa s tym od vcera a ziadne
rozumne som nenasiel.


Dakujem,

Tomas.
