I have dovecot (2.2.16, see dovecot -n at end) installed to /opt on CentOS 6
for access on a local network. I would like to create an archival mail
account which will reduce the primary account file size and still make older
emails easily accessible. How can I set specified folders in this Maildir
read-only with ACL? For example, I included this in the dovecot-acl file to
see: http://wiki2.dovecot.org/ACL
There is the "owner" identifier. But, IMHO, the owner always has the
permission to change the ACLs.
specify protected folders in the archives@ Maildir but it did not work:
"Email 2013/*" user=archives lrs
"Email 2014/*" user=archives lrs
The user is named "archives"?
Also tried this on folders without spaces with no success (the folders were
still delete-able by the user via the Thunderbird client). Each "Email..."
folder has several child folders that should also be read-only.
Better use doveadm acl add command to change ACLs. For whatever reason, I
found the ACLs may not get effective immediately otherwise.
If you really want to have readonly-Submailboxes, you need to do it via
filesystem permissions.
BTW, what is the maximum size for a Maildir that Dovecot can comfortably
handle?
I haven't found a mail client, that could cope with Dovecot's limits, so I
cannot say. Or to phrase this sentence differently, if there was trouble,
the client couldn't cope with the number of messages.
