macOS Server: Dovecot und shared mailboxes

[j33n5]

Tag allerseits,

ich möchte gerne für Kollegen bestimmte Mail-Ordner eines Users freigeben. Bisher habe ich damit allerdings wenig Erfolg.

Kann mir jemand behilflich sein, die Anleitungen im Netz sind entweder nicht für Mac oder für mich unverständlich.

Ich habe Schwierigkeiten die Zusammenhänge zwischen ACL, name spaces und den tatsächlich vorhanden Ordnerrechten zu verstehen. Bin für jede Hilfe dankbar!

# doveconf -n

liefert das:

Okay, es scheint zu laufen, ein:

doveadm acl set -u USER1  INBOX user=USER2 lookup read

Hat es vollbracht. Es werden die Dateien dovecot-acl-list und dovecot-acl entsprechend geändert.

Nun habe ich ein weiteres Problem, meine User heißen zum Teil x.nachname und dadurch können Ordner von diesen Usern nicht abonniert werden. Ich habe versucht, das entsprechend diesen Beitrags zu fixen: https://dovecot.org/list/dovecot/2014-April/095749.html
und namespace separator von „.“ auf „/“ umgestellt. Jetzt tauchen die Ordner auf, ich kann sie jedoch nicht abonnieren. Ich gehe davon aus, dass es sich um ein Rechtsproblem handelt.
