Linking mdbox directories

Alex Crow — 2013-05-20T11:00:49

Hi Timo/list,

We have a scenario in which some email accounts on dovecot (stored in 
mdbox, separate paths for indexes, email, ALT storage and also using SIS 
for attachments, LDAP directory) need their names changed. I know we 
could just change the mail LDAP attribute (and leave mailMessageStore 
alone) so they keep the same directories on disk, but this would throw a 
spanner in the works for our backups.

Would it be possible to create a hard link of the user's directories 
under the new name, and change the LDAP mailMessageStore attribute to 
point to these without stopping and starting dovecot? And after a while 
unlink the original locations? Or would this mess up dovecot's internal 
state?

Thanks

Alex

Empty file in maildirs

Roel Wagenaar — 2013-05-20T08:29:24

I am cleaning up some old users, and found that in every maildir folder there is
an empty file called maildirfolder, created at the time the original dovecot was
installed.

Is this empty file necessary for dovecot, or is it left there in an upgrade
proces and can it be removed?

Dovecot 2.1.7, on Debian wheezy.

v2.2.2 released

Timo Sirainen — 2013-05-19T23:31:01

http://dovecot.org/releases/2.2/dovecot-2.2.2.tar.gz
http://dovecot.org/releases/2.2/dovecot-2.2.2.tar.gz.sig

It's been a while since v2.2.1. I think all of the bad bugs in v2.2
series should be fixed by now, so here's a new release. I think there
are still some small URLAUTH bugs left though, so you might want to wait
before enabling it in production (imap_urlauth_host is empty by default,
which disables it).

+ zlib: Keep the last mail cached uncompressed in a temp file. This
  fixes performance when doing small partial fetches from a large
  mail.
+ acl: If plugin { acl_defaults_from_inbox = yes } is set, get the
  default ACLs for private and shared namespaces from the user's INBOX.
  (This probably will become default in v2.3.)
+ pop3: Added pop3_deleted_flag setting to switch POP3 deletions to
  only hide the messages from POP3, but still be visible via IMAP.
- ACL plugin: Mailbox creation wasn't actually checking any ACLs
  and always succeeded (due to some v2.2 API changes). The created
  mailbox couldn't have been accessed though, so this couldn't have
  caused any data leak.
- IMAP: Various URLAUTH fixes.
- IMAP: Fixed a hang with invalid APPEND parameters.
- IMAP LIST-EXTENDED: INBOX was never listed with \Subscribed flag.
- mailbox_list_index=yes still caused crashes.
- maildir: Fixed a crash after dovecot-keywords file was re-read.
- maildir: If files had reappeared unexpectedly to a Maildir, they
  were ignored until index files were deleted.
- Maildir: Fixed handling over 26 keywords in a mailbox. 
- Maildir++: Fixed mail_shared_explicit_inbox=no 
- namespace { prefix="" list=no } was listing mailboxes.
- imap/pop3-login proxying: Fixed a crash if TCP connection succeeded,
  but the remote login timed out.
- Case-insensitive search/sort didn't work correctly for all unicode
  characters, as specified by i;unicode-casemap comparator. If full
  text search indexes were used, they need to be rebuilt for old mails
  to be handled correctly. (This bug has existed always in Dovecot.)

Error: dict client sent broken reply

Chris Richards — 2013-05-19T21:33:52

I've been mucking about, experimenting with the expire plugin and using a
dictionary.  I've got the iteration query working when I do a normal
expunge using:

doveadm expunge -A mailbox "INBOX.Trash" savedbefore 1w

and expunging works as expected.  However, I've got over 12,000 accounts
on this server, so I was hoping using the expire plugin to could help out.
 I've configured the plugin, and things kinda work, except that somewhere
between 3700 and 3800 users, I abort with this:

doveadm(someuseraccount< at >somedomain): Error: dict client
(/var/run/dovecot/dict) sent broken reply
doveadm(someuseraccount< at >somedomain): Error: Dictionary iteration failed
doveadm: Error: Failed to iterate through some users

It consistently fails at the same user.  If I delete that user from the
expire database, then it appears to fail on the next user.

I also see this in the logs:

dovecot: dict: Error: dict client: COMMIT: Can't commit while iterating

I've absolutely no idea where to go from here to troubleshoot this.  Any
guidance would be appreciated.

Thanks,
Chris

Configure dovecot to provide SASL authentication

Peter Skensved — 2013-05-19T15:51:12

   Hi,
  I'm trying to get dovecot to provide SASL authentication for
postfix My setup appears to be working but I'm not 100% certain
I've got it right. I've come across several examples for dovecot
version 1 but I'm running 2.0.9.  The output of doveconf -n is here :

 2.0.9: /etc/dovecot/dovecot.conf
# OS: Linux 2.6.32-279.2.1.el6.x86_64 x86_64 CentOS release 6.3 (Final) 
auth_debug = yes
auth_verbose = yes
disable_plaintext_auth = no
mbox_write_locks = fcntl
passdb {
  driver = pam
}
protocols = imap
service auth {
  unix_listener /var/spool/postfix/private/auth {
    mode = 0666
  }
}
ssl_cert = </etc/pki/dovecot/certs/dovecot.pem
ssl_key = </etc/pki/dovecot/private/dovecot.pem
userdb {
  driver = passwd
}


 Specifically : are the "service auth", userdb and passdb
sections correct ? And the mode ? Or is it too permissive ?


  For completeness the postfix setup is here :

smtpd_sasl_auth_enable = yes
broken_sasl_auth_clients = yes
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_security_options = noanonymous

smtpd_helo_restrictions =
    permit_mynetworks,
    reject_non_fqdn_helo_hostname,
    reject_invalid_helo_hostname,
    permit
#
smtpd_sender_restrictions =
    permit_mynetworks,
    reject_non_fqdn_sender,
    reject_unknown_sender_domain,
    permit
#
smtpd_recipient_restrictions =

Dovecot 2.2.1 LDA and sieve (lack of) errors

Jim McNamara — 2013-05-18T14:56:10

Hello again, all. Of course after posting yesterday that all was well 
with my setup, turns out all is not well. The problem I'm having is with 
dovecot-lda functioning and making deliveries to my mailbox, but the 
sieve scripts don't seem to have any effect. Attempts at logging what 
is/isn't happening have been total failures.

Managesieve seems to work fine, port 4190 is open on the server and it 
allows the tunderbird plugin to function, I can create and edit scripts 
with the plugin. For some reason it doesn't seem to auto-compile the 
scripts to binary form, but if I just need to do that manually I can 
live with it. I only mention the lack of auto-compiling in case that 
sheds light on what is wrong with the LDA or sieve.

I'm running the current dovecot, 2.2.1 along with pigeonhole 0.4.0. Here 
is the config:

root< at >hostname:/usr/local/dovecot-2.2.1# doveconf -n

I've set the lda specific logs to /dev/stderr because I'm running 
dovecot through daemontools, and that is what it logs. Daemontools 
redirects /dev/stderr to /var/log/qmail/qmail-dovecot/current. I had 
tried logging to /var/log/dovecot/lda.log, that file exists, the 
directory is 775 dovecot:dovecot, but the file size remained 0. Very 
little appears in the dovecot logs with lda -

The sieve issue is as follows: I have a very simple sieve script. the 
managaesieve utility accepts the script, here is the contents of the 
$HOME/.sieve directory:

root< at >hostname:/home/vpopmail/domains/domain.com/jim/.sieve# ls -al
total 20
drwx------ 3 vpopmail vchkpw 4096 May 18 02:24 .

-rw------- 1 vpopmail vchkpw  315 May 18 02:24 night-test.sieve
drwx------ 2 vpopmail vchkpw 4096 May 18 02:24 tmp

The contents of dovecot.sieve itself are:

root< at >hostname:/home/vpopmail/domains/domain.com/jim/.sieve# cat 
dovecot.sieve
#
# 2013-5-17
#
require ["fileinto", "envelope", "vnd.dovecot.debug"];
if header :contains ["from"] "sub1.domain.com" {
     debug_log "match happened and syntax changed for testing purposes";
       fileinto
   "INBOX.folder2";
} else {
     debug_log "can't catch a cold when wet snowy and cold";
   keep;
}

The compile of the script works fine as user vpopmail:

vpopmail< at >hostname:~/domains/domain.com/jim/.sieve$ sievec dovecot.sieve

A diff between dovecot.svbin and /tmp/dovecot.svbin shows no difference. 
Neither of the debug lines show up anywhere in the logs.

the main inbox rather than INBOX.folder2. Interestingly, if I run 
sieve-test on the mail, it tells me it should have been moved to 
INBOX.folder2:

Both /var/qmail/bin/preline and /usr/local/libexec/dovecot/dovecot-lda 
exist.

Any idea why my sieve doesn't seem to take effect?

Thanks for reading.

How to configure ssl cert chain in dovecot 10-ssl.conffile

Bu Xiaobing — 2013-05-18T09:06:09

Hi there,

Does anyone know how to do this:

"Put all the certificates in the ssl_cert file. For example when using a certificate signed by TDC the correct order is:

    Dovecot's public certificate
    TDC SSL Server CA
    TDC Internet Root CA
    Globalsign Partners CA "

I try to set these parameters in the conf.d/10-ssl.conf as below, but it seems doesn't work.

---
ssl_cert = </etc/pki/dovecot/certs/mail.mymailserver.com.crt
ssl_cert = </etc/ssl/certs/dovecot/sub.class1.server.ca.pem
ssl_cert = </etc/ssl/certs/dovecot/ca.pem
----

I even cat mail.mymailserver.com.crt sub.class1.server.ca.pem certs/dovecot/ca.pem into one singe file, and define ssl_cert = < /path/to/the/singcertfile.pem, but it doesn't work too.

In my apache httpd server httpd.conf file  I can define:
--
SSLCertificateChainFile /etc/pki/dovecot/certs/sub.class1.server.ca.pem
SSLCACertificateFile /etc/pki/dovecot/certs/ca.pem
--
And it well work fine.

Thinks for any suggest.

spam.sh is message processing script which interacts with spamassassin.
I've tested pipe with spam.sh that redirects stdin to /dev/null and returns
0 but errors were logged anyway.
Note that spam.sh runs, getting the message from sieve and processing it to
spamassassin without a problem, but "broken pipe" is being logged.

doveadm altmove to gzipped-mdbox

Claus — 2013-05-17T13:59:08

Hi,

im wondering if it's possible to store old messages in a compressed 
mdbox on alternate storage.
The main storage is uncompressed mdbox.

I tried something like: doveadm -Dv -o "plugin/zlib_save=gz" altmove -u 
testuser sentbefore 8d

Could someone tell me if it's possible and give me a hint how this can 
be done?

I tried this with dovecot-2.2

ACLs - creating new top level folders

Ingo Rogalsky — 2013-05-17T00:46:02

Hi,

I'm wondering, whether it's possible, to define an ACL on the mailbox 
itself. We use Dovecot 1.2.15 (included in Debian 6) and maildir 
filesystem layout:

/home/mail01/user1/Maildir/new           \
/home/mail01/user1/Maildir/cur            Inbox
/home/mail01/user1/Maildir/tmp           /
/home/mail01/user1/Maildir/.folder1/new  \
/home/mail01/user1/Maildir/.folder1/cur   folder1
/home/mail01/user1/Maildir/.folder1/tmp  /
...

Assigning an ACL with full access rights for user2 to the folder Inbox 
works as expected. user2 can create subfolders of Inbox, too. But he 
can't create a new folder like folder1 parallel to Inbox. Is there a 
possibility of defining an ACL on the mailbox of user1 itself? Or do we 
need to create all subfolders beneath Inbox like this is usual with 
other IMAP servers?

Ingo

Ubuntu-12.04-LTS repos with Dovecot-2.2 and Pigeonhole

2013-05-16T17:30:22

Hi,
 
 I would like to take advantage of new features in Dovecot 2.2 on my servers. But I'm having difficulties to build packages for Ubuntu-12.04-LTS.
 
 Does anyone know a repository that has new stable versions for Dovecot and Pigeonhole ?
 
 Thanks !

[PATCH] example-config: fix to also distribute auth-dict.conf.ext in

Christian Wiese — 2013-05-16T15:14:34

Hi,

When trying to patch the dovecot 2.2.1 release with latest upstream
patches I generated out of the repository, the patch fails to apply,
because 'doc/example-config/conf.d/auth-dict.conf.ext' is not
distributed within the release tarball.

Attached patch should fix the issue.

Cheers,
Chris

quota with imapc

pvsuja — 2013-05-16T10:31:15

Dear dovecot team,

I have set up my mail system with a mail gateway connecting to mail server
using imapc.
Now I need my web mail client to show up the quota info.
I enabled quota plugins in dovecot.conf.
The problem is since all mails reside in the server, the web mail which is
in mail gateway always shows the quota as 0.
Is there any way the plugin will get quota info from the mail server?

I am attaching my conf 

## Dovecot configuration file in

mail_uid = imapproxy
mail_gid = imapproxy
mail_home = /home/imapproxy/%u
mail_location = imapc:~/imapc

protocols = imap


##
## imapc settings
##

imapc_host = mailserver.example.com
imapc_port = 143
imapc_ssl = starttls
imapc_ssl_ca_dir = /etc/postfix/certs

##
## auth settings
##

auth_mechanisms = plain login

passdb {
  driver = imap
  args = host=mailserver.example.com ssl=starttls
ssl_ca_dir=/etc/postfix/certs
  default_fields = userdb_imapc_user=%u userdb_imapc_password=%w
ssl=starttls
}
userdb {
  driver = prefetch
}


mail_plugins = $mail_plugins quota
plugin {

quota = maildir:User quota
quota_rule = *:storage=200M 

}
protocol imap {
  # Space separated list of plugins to load (default is global
mail_plugins).
  mail_plugins = $mail_plugins imap_quota
}

##
## SSL settings
##

ssl = required
disable_plaintext_auth = yes
#verbose_ssl = yes
ssl_cert = </etc/postfix/certs/public_cert.pem
ssl_key = </etc/postfix/certs/private_key.pem

Greetings.

question about /var/spool/mail/xxx

2013-05-16T07:51:39

this is Redhat 6.3
I installed sendmail and dovecot.
but sendmail can continue send mail as MTA
all mails go to /var/spool/mail

this is problem for dovecot. dovecot cannot get it goto dovecot inbox.

if setup mailbox poing to /var/spool/mail/%u, it is workable
but if set up maildir to somewhere else ,I cannot receive mail by dovecot.

Fatal: Can't finish POP3 UIDL command

stevenfah — 2013-05-15T15:03:28

I have been setting up a new mail server and copied our client's old mail to
it. The old server has Courier (under Plesk), we're using Dovecot on the new
server.

Most accounts seem to work fine (under IMAP or POP3), but for a few we're
getting the following in the /var/log/mail.err.


Error: Message ordering changed unexpectedly (msg #1: storage seq 140 -> 1)
Fatal: Can't finish POP3 UIDL command


And the affected accounts can't get at their email. Things work ok if people
switch to IMAP but for some of our clients that is a difficulty, so we
really need POP3 working.

I used the Perl script given here to convert the mailboxes.

The only fix we've found is the rename/delete the Dovecot-uidlist file for
the affected mailboxes and we've done that, as it was only a few. The issue
now is that more mailboxes are coming with the same error, even though they
were fine originally.

dovecot 2.0 -> 2.1 sieve problem

Trever L. Adams — 2013-05-14T18:54:06

I had a completely working setup before. I upgraded, now I get:

Error: 7LUaNYqHklG6EAAApwKjnA: sieve: execution of script (null) failed,
but implicit keep was successful

sieve = /home/vmail/%Ld/%Ln/.dovecot.sieve
sieve_dir = /home/vmail/%Ld/%Ln/sieve (this was ~/sieve)

I am not quite sure what is going on. Is anyone else seeing this? Any
idea on what has changed? (I am not readily seeing it in changelogs or
mailing lists.)

Thank you,
Trever

Hello everyone.

I have dovecot version 1.2.8 installed from source. This morning I 
installed the sieve plugin to sort emails, and though the install 
reported no errors, the plugin doesn't seem to function, and no mention 
of it is made in the logs when I turn on verbose logging.

Here is the config.log from sieve

root< at >myplace:/usr/local# head dovecot-1.2-sieve-0.1.19/config.log
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by Dovecot Sieve configure 0.1.19, which was
generated by GNU Autoconf 2.67.  Invocation command line was

   $ ./configure --with-dovecot=../dovecot-1.2.8/

That compiled cleanly, then make and make install also proceeded without 
error.

With verbose logging enabled, the only times "sieve" appeared in the 
logs was when I tried to load it as a plugin for imap -

grep sieve /var/log/qmail/qmail-dovecot/current |tai64nlocal
2013-05-14 09:20:05.091635500 FPlugin sieve not found from directory 
/usr/local/lib/dovecot/imap
2013-05-14 09:20:06.120848500 FPlugin sieve not found from directory

2013-05-14 09:20:08.164247500 FPlugin sieve not found from directory 
/usr/local/lib/dovecot/imap

Once I removed it from being loaded as an imap plugin and used it only 
as an lda plugin, it hasn't appeared in the dovecot logs. It also isn't 
logging where I asked it to in the config file (log_path: 
/var/log/qmail/sieve/dovecot.log, or info_log_path: 
/var/log/qmail/sieve/dovecot.log), but that files was touched and all 
directories below /var/log/qmail/sieve have the correct permissions for 
dovecot to write there:

ls -al /var/log/qmail/sieve/
total 16
drwxr-xr-x 2 dovecot dovecot  4096 May 14 11:04 .
drwxr-xr-x 7 qmaill  root    12288 May 14 11:04 ..
-rw-r--r-- 1 dovecot dovecot     0 May 14 11:04 dovecot.log

Can anyone suggest an error they see or what I can do to get my errors 
with the sieve config logged somewhere?

Thanks for your help and insight.

protocols and privileges

andreas graeper — 2013-05-14T13:41:16

hi,

1)
protocols = pop3
but when starting the service, output tells about imap. when mua fetches
mails ~/mail/.imap/INDEX is created.

2)
i have some users uid=500 .. 505. src in /var/mail/%u, owner is <user>.mail
and home-directories /home/<user> - owner is <user>.users

when dovecot tries to create directory /home/<user>/mail then it tells for
user xyz (uid = 502)

 euid=502(xyz)  egid=100(users) missing +w permission /home/xyz , euid is
not dir owner.

but /home/xyz is owned by xyz.users and mod = 0700     ( drwx------ )

same environment for uid = 501 works great !


thanks in advance
andreas


? permission lookup from /home/xyz/mail failed
do i have to create that mail directory manually ?

2.2.1 and quota-status

Christian Rößner — 2013-05-14T09:20:53

Hi,

maybe this question already came up and I missed it in my mails, but if not… :

I have configured Quota for Dovecot since decades and now with the new policy service, I wanted to include this into Postfix. I have followed Ralf's Blog and there a two Problems:

I need to do this:

ls -la /var/run/dovecot/config
srw------- 1 root root 0 May 14 11:06 /var/run/dovecot/config

chown vmail  /var/run/dovecot/config

ls -la /var/run/dovecot/config
srw------- 1 vmail root 0 May 14 11:06 /var/run/dovecot/config

Where can I tell Dovecot to set user vmail here? If I do not do this, I get the following error in the logs:

May 14 10:54:50 mx0 dovecot: quota-status(c< at >roessner-network-solutions.com): Error: user c< at >roessner-network-solutions.com: Error reading configuration: net_connect_unix(/var/run/dovecot/config) failed: Permission denied

Also the following test does not succeed:

telnet localhost 12340

Nothing in the logs. Just an empty answer.

Autocreation the home folder

Joan — 2013-05-13T06:42:50

Sorry if this has been already asked, but I haven't been able to find a
solution, I am trying to migrate a dovecot 1.2 config to 2.1, the 'dovecot
-n > dovecot.conf' migrated all the setup without issues, and the mail is
working as expected.

The only issue I've had is with the change with the mail_location,
mail_home, that in the 2.1 versions can't be on the same path.

After reading in the wiki the various config options (
http://wiki2.dovecot.org/VirtualUsers/Home) I opted to use the 3rd:

  Home directory under mail, for example:
    Maildir: home=/var/vmail/domain/user/home/ mail=/var/vmail/domain/user/
    mbox: There's really no good and safe way to do it.


So I changed from:
  mail_location = maildir:/home/vmail/%d/%n
  mail_home = /var/vmail/%d/%n
To:
  mail_location = maildir:/home/vmail/%d/%n
  mail_home = /var/vmail/%d/%n/home

The problem is that those home directories are not created (the mailboxes
already existed) automatically, and I am getting these errors:

========================================================

Am I supposed to create the folders via an external script? Or is there any
option to make this automatic.

Joan
