Re: [Dovecot] Corrupted index cache file and high CPU usage
Yes, it is reproducible. About the file, I have tarred up the original maildir before I deleted the dovecot.index.cache, so when I try to bring in the original file, a 'cat' does no harm. Moreover, I've tried to do this will all files on the virtual machine, same results - no harm.

Sorry for the partition/drive terminology mess up. So it's reproducible? You could see if you can reproduce it by simply reading the file(s) that are causing problems. Like with zsh: cat **/* /dev/null

[Dovecot] mbox, hierarchical folders/folders and IMAP
Hello, I'm now dealing with funny problem. I try to use Dovecot (2.1.rc1, actually) and mbox format to store old mailing, to keep logic of one folder = one file. If I'd choose Maildir, I'd be able to create hierarchical folders (like OldMail - Maillists - Dovecot), and in fact on disk such a folders would be stored as real folders with dots in their names. In PHP it is easy to create with imap_createmailbox() function, I'd simple fire it 3 times (for OldMail, for OldMail.Maillists and for OldMail.Maillists.Dovecot). But when I do the same with mbox, in fact it creates separate files (indeed, named OldMail, OldMail.Maillists and OldMail.Maillists.Dovecot) instead of creating filesystem folders (OldMail/Maillists/Dovecot). PHP is not guilty, Thunderbird won't create such folders as well. I can only create folders myself (say, with mkdir in the shell), chown it, and the it perfectly works in IMAP. Now I just wanted to know, are there any way to create IMAP-folders and subfolders using standard IMAP functionality? Thank you, Alexander
Re: [Dovecot] Corrupted index cache file and high CPU usage
Selinux wasn't running. I can reproduce the problem with this setup: - restore the maildir with the broken index.cache - run `/usr/bin/doveadm -D expunge -A mailbox Trash savedbefore 1w` in an infinite loop - use horde webmail to access the mail with IMAP - randomly display messages I could reproduce the problem on: Linux-2.6.37-hardened-r7 Linux-2.6.39-hardened-r8 Linux-3.0.4-hardened-r5 Linux-3.0.6-gentoo Linux-3.1.4-gentoo However I failed to reproduce the problem on: Linux-2.6.36-hardened-r9 So it seems it was introduced in 2.6.37. I'm going to inspect it later on.

[Dovecot] 2.1.rc1 (056934abd2ef): virtual plugin mailbox search pattern
Hello Timo,
With dovecot 2.1.rc1 (056934abd2ef) there seems to be something wrong
with virtual plugin mailbox search patterns.
I'm using a virtual mailbox 'unread' with the following dovecot-virtual file
$ cat dovecot-virtual
*
unseen
For testing propose I created the following folders with each containing
one unread message
INBOX, INBOX/level1 and INBOX/level1/level2
2.1.rc1 (056934abd2ef)
1 LIST *
* LIST (\HasChildren) / INBOX
* LIST (\HasChildren) / INBOX/level1
* LIST (\HasNoChildren) / INBOX/level1/level2
* LIST (\HasChildren) / virtual
* LIST (\HasNoChildren) / virtual/unread
1 OK List completed.
2 STATUS INBOX (UNSEEN)
* STATUS INBOX (UNSEEN 1)
2 OK Status completed.
3 STATUS INBOX/level1 (UNSEEN)
* STATUS INBOX/level1 (UNSEEN 1)
3 OK Status completed.
4 STATUS INBOX/level1/level2 (UNSEEN)
* STATUS INBOX/level1/level2 (UNSEEN 1)
4 OK Status completed.
5 STATUS virtual/unread (UNSEEN)
* STATUS virtual/unread (UNSEEN 1)
5 OK Status completed.
Result: virtual/unread shows only 1 unseen message. Further tests showed
it's the one from INBOX. The mails from the deeper levels are not found.
Downgrading to 2.0.16 restores the correct behavior:
1 LIST *
* LIST (\HasChildren) / INBOX
* LIST (\HasChildren) / INBOX/level1
* LIST (\HasNoChildren) / INBOX/level1/level2
* LIST (\HasChildren) / virtual
* LIST (\HasNoChildren) / virtual/unread
1 OK List completed.
2 STATUS INBOX (UNSEEN)
* STATUS INBOX (UNSEEN 1)
2 OK Status completed.
3 STATUS INBOX/level1 (UNSEEN)
* STATUS INBOX/level1 (UNSEEN 1)
3 OK Status completed.
4 STATUS INBOX/level1/level2 (UNSEEN)
* STATUS INBOX/level1/level2 (UNSEEN 1)
4 OK Status completed.
5 STATUS virtual/unread (UNSEEN)
* STATUS virtual/unread (UNSEEN 3)
5 OK Status completed.
Result: virtual/unread shows 3 unseen messages as it should
The namespace configuration is as following
namespace {
hidden = no
inbox = yes
list = yes
location =
prefix =
separator = /
subscriptions = yes
type = private
}
namespace {
location = virtual:~/virtual
prefix = virtual/
separator = /
subscriptions = no
type = private
}
I've also tried this with location = virtual:~/virtual:LAYOUT=maildir++
leading to the same result.
Thanks,

[Dovecot] Upgrade/Migration
Current box: CentOS 4.x (32 bit), dovecot 1.02, mbox format
New box (supposed): CentOS 6.x (32/64 bit ? ), dovecot 2.04, mbox format
The server have about 3.000 active users (unix users); /var/mail is about
100 GB; /home/Users about 150 GB
I read the docs and searched on the net, but still request hints for
planning the migration.
32/64 bit?
Tricks to avoid users get all messages ...?
Better first update the old server from 1.02 to 2.0x or ..?
Any hints/comment appreciated ;-)
Thanks, P.

[Dovecot] Dovecot imap proxy to nginx, incompatible
It appears that using dovecot to proxy to nginx imap proxy doesn't work.
From tcpdump and browsing the source it appears dovecot sends,
C CAPABILITY\r\nL LOGIN user pass\r\n
and nginx only responds to the CAPABILITY command. Is this a problem
with dovecot sending the two commands without waiting for the first to
complete or is it nginx's trouble with not handling it correctly?
A quick test with a perl script confirms:
#!/usr/bin/perl -w
$|++;
use IO::Socket;
use strict;
my ($host, $user, $pass) = @ARGV;
my $s = new IO::Socket::INET(Proto = 'tcp', PeerAddr = $host, PeerPort
= 143);
die Could not create socket $!\n unless $s;
while($s) { print $_; last if /OK/; }
print $s C CAPABILITY\r\nL LOGIN $user $pass\r\n;
while($s) { print $_; last if /OK/; }
print $s Q logout\r\n;
while($s) { print $_; last if /OK/; }
close($s);
## Output:
* CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND
UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS
LIST-EXTENDED I18NLEVEL=1 QUOTA AUTH=PLAIN
C OK completed
* BYE
Q OK completed
[Dovecot] sieve in sql or reporting
With dovecot2 and pigeonhole sieve/managesieve is it currently possible to store sieve rules in an sql database? If not is there a way to query all accounts; looking for things like active vacation rules? Regards, Bradley Giesbrecht

I'm working on an evolution of the sieve_pipe plugin called the sieve_extprograms plugin. One of the things it adds is a new action command called execute, which may suit your needs. It will only be available for Dovecot v2.1 though.

Oh btw, if you are looking for a way to disable vacation rules after
some period of time, you can use the date extension
(http://tools.ietf.org/html/rfc5260#section-4). For example:
require [date, relational, vacation];
if currentdate :value le date 2011-12-09 {
vacation I'm out of office this week. I'll be back on Saturday
10th to reply to your e-mails.;
}

[Dovecot] dovecot / postfix mail bounce problem
Hello,
i use a globalsieve rule to collect spam for all mail accounts in a specific
mailbox.
Here is the code:
vi /var/vmail/globalsieverc
require [fileinto];
# Move spam to junk folder
if not address :is to antis...@xxx.com {
if header :contains X-Spam-Flag [YES] {
redirect antis...@xxx.com;
stop;
}
}
But the spam mails are not delivered.
cat /var/log/mail.info
postfix/pipe[32301]: AD8F78E2128D: to=antis...@xxx.de, relay=dovecot,
delay=0.14, delays=0.08/0/0/0.06, dsn=5.4.6, status=bounced (mail forwarding
loop for antis...@xxx.de)
Why is there a loop? I don't unterstand that.
Any help?
Thanks!
Iced
