Hello,
After a global system restore of my NethServer 7.9.2009, the admin mail box is in read only mode.
Users mail box works good. I have this problem only for the admin@
In Thunderbird it’s like in read only mode, no changes (to receive, unread/read) can be done.
In Sogo I can change read/unread status but only for ‘old’ emails, ‘new’ email aren’t visible and clickable.
Appened to me with a disaster recovery.
You should chown the mail directory with the correct user/group, but i can not remember the correct informazioni.
