Dear List,
this is my first mail to this list. I'v tried to carefully review all given information towards the Shared Folder subject I could find in the archive / mailing list / wiki. And so far I'm also aware that Timo hasn't put it on the active tasklist for the 1.0 release.
Citing the track http://dovecot.org/pipermail/dovecot/2003-October/002493.html I was wandering, wether any further attempt has been made, to use the given functionality for real work. To be more precise, wether anybody has done
- delivery of mailboxes to a shared maildir
- offering these maildirs through a given namespaceBefore bothering here without any local experience, I'v set up a dov-server (1.0alpha3) on a debian sid. As an MTA postfix is doing the job. Within postfix I did set up a virtual domain and the needed maps (mailbox, alias). I'm able to deliver successful with the standard postfix functionality to the given filesystem structure (fs=ext3). If it is on any help, I can post the relevant config files.
As good practice, all mail is delivered to given mailbox-owner with 0600 permission for the new subdir. Hence, can't be seen by any shared-maildir user (unless owner uid matches:)
From here on I'v tried to switch from debians default postfix delivery-strategy (mailbox_command = procmail -a "$EXTENSION") to given dovcot deliver process (mailbox_command = /usr/lib/dovecot/deliver). The primary aim is to define a strategy to deliver with 0660 rights which will enable group read-write access to the given Mailstore.
I have adopted the dovecot.conf enableing a listening socket
...
default_mail_env = maildir:/home/%u/Maildir: \
INDEX=/home/%u/MaildirIndex
namespace private {
separator = /
prefix =
inbox = yes
}
namespace public {
# the prefix needs to be postponed with the separator
prefix = Public/
# the location path given as [<mailbox-type>:]<path>/mailbox
location = maildir:/home/SharedMaildirs
separator = /
inbox = no
hidden = no
}
auth default {
...
# using deliver through a socket
socket listen {
master {
path = /var/run/dovecot/auth-master
mode = 0666
}
}
}
and configured the subsequent dovecot-deliver.conf
...
auth_socket_path = /var/run/dovecot/auth-master
mail = maildir:%h/Maildir/
umask = 0007
auth_verbose = yes
use_syslog = yes
just to see, whether a manual call
/usr/lib/dovecot/dovecot-deliver -d <user> <testmailwould do the trick. Well, I got the delivered mail, but files are not installed with the etimated previledges.
Can someone can point me to the clou?
Greetings Ralf
PS: I also read about posix-acl's support. But my test's didn't allow a successful read ....
