What client do you use?
Are there folders shared from user1 to user2?
what does dovecadm acl get -u -m shared..mailbox show?
doveadm debug -u user2 -m shared..mailbox
Whats in your logs? Enable debug log and look for errors.

According to http://wiki2.dovecot.org/SharedMailboxes/Shared the "list =
Children" hides the namespace from the imap list command, if there is no
folder shared to the user. Try to set list = yes that should show the
shared namespace in the imap list.
Also scroll down to shared mailbox listing, you should setup a dict so
that dovecot knows which folders are shared.

inbox = yes

Re: dovecot Digest, Vol 154, Issue 14
Thanks, Hajo
This mostly works, but we can’t seem to send an arbitrary mailbox name with
UserDB, we have to initialize it in the config:
"namespace/inbox/mailbox=Junk namespace/inbox/mailbox/Junk/name"="Spam"
seems to initialize the folder somehow so that the subsequent
"namespace/inbox/mailbox/Junk/auto"="subscribe"
and
"namespace/inbox/mailbox/Junk/special_use"="\Junk"
have something to act upon.
(the first line doesn't work quite properly, however - it ends up
causing a folder named "" to show up)
we've noticed that if we set a very minimal config for the mailbox in
the main config (that wouldn't cause the mailbox to be autocreated),
that this also initializes the folder name allowing for subsequent auto
and subscribe directives to be processed for it:
namespace inbox {
inbox = yes
mailbox "Spam" {
auto = no
}
}
is there some userdb response that will simply initialize the folder
(without doing any name remapping) in the same way that the above config
lines do?
we have tried a few things based off Hajo's first line, but nothing we
guess at seems to do the trick. ie:
"namespace/inbox/mailbox"="Spam"
"namespace/inbox/mailbox=Spam"=“Spam"

I didn't see my original email show up on the mailing list so I'm resending. To
recap, is it possible to backup all users to a local drive with doveadm?

Dovecot IMAP permissions issue (see original)
/ >/What purpose does vpopmail serve that dovecot alone does not? Isn't it just an ancient leftover from historic qmail times? qmail and vpopmail are still quite prominent on the Internet. I see no reason to change my setup at the moment. Possibly I could re-architect to read user info directly from mysql but that would not help with the fact that dovecot then likely read or write as the wrong userid on the system (since mailboxes are virtual). Have recreated the same issue (sans mysql) on another vpopmail system. Regardless, it is a bug. From my process list: 25813 vpopmail 20 0 26468 4984 4016 R 0.7 0.0 0:00.02 imap 26730 vpopmail 20 0 28332 5940 4212 S 0.7 0.0 0:00.06 imap For certain, imap being ANY other user than root means that the /var/run/dovecot/imap-* sockets would be unwritable.

How to understand NFS lookup (requests) spike?
Hi, I'm are running a classic Dovecot setup: About ten thousand connected users mailbox in Maildir format shared via NFS (NetApp) Director for POP/IMAP Delivery via Dovecot LDA All works fine but sometimes I see a spike on the load of POP/IMAP servers and high disk usage (close to 100%) on NFS NetApp. When this happens on NFS stats (of POP/IMAP) I can see an high volume of "lookup, remove, rename" requests. Example (avg is during normal load, max is request number during the spike): Lookup avg 100 max 700 Remove avg 50 max 300 Rename avg 50 max 300 Getattr avg 200 max 250 Total NFS avg 600 max 1800 I think that some users are doing some kinds of "intensive" operations on their mailbox but what and who? I am currently using "iotop" to monitor the activity of individual users but I can't figure out who is causing the high number of I/O requests. Have you any suggestions?
