Answer is that I missed the `dovecot-shared' files in the directory where it did not worked. :) I've added this file where it was missing, and now I can say that the patch totally fix my issue: . select public.Stg-ee * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 12 EXISTS * 0 RECENT * OK [UNSEEN 2] First unseen. * OK [UIDVALIDITY 1254336597] UIDs valid * OK [UIDNEXT 13] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest . OK [READ-WRITE] Select completed. Thanks a lot Timo ! Cheers, -- Julien Danjou // ᐰhttp://julien.danjou.info pgpojb9V1ufUf.pgp Description: PGP signature

[Dovecot] Permanent flags not announced and public mailbox with per-user index
Hi,
I've a set of public mailboxes that all users can access.
The index is stored per user, so each user can mark the message as read
for themselves.
This is with dovecot 1.2.10.
However, when selecting the mailbox, system flags are not announced as
permanent but only as session flags:
3619 SELECT "public.Admin"
* FLAGS (\Answered \Flagged \Deleted \Seen \Draft)
* OK [PERMANENTFLAGS ()] Read-only mailbox.
* 324 EXISTS
* 0 RECENT
* OK [UNSEEN 171] First unseen.
* OK [UIDVALIDITY 1254326934] UIDs valid
* OK [UIDNEXT 1102] Predicted next UID
* OK [HIGHESTMODSEQ 1] Highest
3445 OK [READ-ONLY] Select completed.
I think (reading the RFC, but I bet you know it better than me) that
FLAGS should also been set in PERMANENTFLAGS since they can be
permanent.
The relevant code seems to be in commands-util.c (dovecot 1.2.11):
void client_send_mailbox_flags(struct client *client, bool selecting)
{
[…]
if (mailbox_is_readonly(client->mailbox)) {
client_send_line(client, "* OK [PERMANENTFLAGS ()] "
"Read-only mailbox.");
} else {
[…]
}
}
Even if it's true that the Maildir is read-only, it's still possible to
store \Seen permanently.
Am I getting things wrong, or is this a bug?
If I'm correct, a simple fix MAY be not to send the PERMANENTFLAGS at
all since the RFC says:
OK [PERMANENTFLAGS ()]
A list of message flags that the client can change
permanently. If this is missing, the client should
assume that all flags can be changed permanently.
Thanks,

[Dovecot] Problem with LSUB and public namespace
Hi,
I'd like to know if the following is normal. I've a setup with 2
namespace (private/public) where each user can use subscriptions.
This problem is triggered by claws-mail, which uses LSUB to get
subscribed mailboxes:
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE
AUTH=PLAIN] Dovecot ready.
. login user password
. namespace
* NAMESPACE (("INBOX." ".")) NIL (("public." "."))
. OK Namespace completed.
. subscribe public.Admin
. OK Subscribe completed.
. LSUB "" "%"
* LSUB () "." "INBOX"
. OK Lsub completed.
LSUB does not return "public" as namespace :-(
Is this a bug in dovecot, a bug in Claws mail, or a misconfiguration of my
dovecot server?
I can provide more info if needed.
Cheers,
--

Dovecot writes > them to a temporary file under home directory. OK, that would explains everything actually, depending on what you call home directory. :-) If it's the user's home, it really has no sense since nowhere it returns something with /var/spool/postfix. Well, anyway, I changed my setup to return absolute path and it seems to work, the mails got delivered. I really suggest you[1] rather try to reproduce and fix the bug, or really disallow relative path in home directory since it's seems partly-broken, or maybe only for large file (your theory :).

Ok, that helps to see what's wrong, thanks: Jul 8 20:50:16 prometheus dovecot: deliver(j...@danjou.info): mkdir_parents_chown(danjou.info/jd/) in directory /var/spool/postfix failed: Permission denied (euid=8(mail) egid=8(mail)) Jul 8 20:50:16 prometheus dovecot: deliver(j...@danjou.info): copy: i_stream_read() failed: No such file or directory Of course, that fails. The thing is that danjou.info/jd/ is the homedir of the user (returned by SQL), and as you saw in my dovecot.conf, there's nothing like /var/spool/postfix for mail_location: mail_location = maildir:/var/mail/vmail/%h /var/spool/postfix is probably the directory where postfix starts dovecot, since it's the home for postfix user. I smell (did not dig into the code) that there's a chdir() to mail_location that is missing for a reason I don't know. (FWIW, I know have 4 mails in Postfix queue on 4 differents account stuck, whereas I still receive others mail without any problems (since I read you ;-).

I've started using Sieve, and everything works fine, I already received a thousand of mails without any problem. However, there's one mail which is stuck in the postfix queue because of that: Jul 8 18:47:51 prometheus dovecot: deliver(j...@danjou.info): mkdir_parents_chown(danjou.info/jd/) failed: Permission denied (euid=8(mail) egid=8(mail)) Jul 8 18:47:51 prometheus dovecot: deliver(j...@danjou.info): copy: i_stream_read() failed: No such file or directory Jul 8 18:47:51 prometheus dovecot: deliver(j...@danjou.info): sieve: msgid=? <1186f9b5-0529-4622-8f4a-58462f9a4...@svr-exchange.siege.ldlc.com>: failed to store into mailbox 'INBOX': Internal error occurred.
