[Dovecot] Maildir + /var/mail
by Greg Pearson 15 Jun '10

15 Jun '10

Hi, I have just switched to Maildir, and I have noticed something. Even though it works properly, I have noticed that a file named /var/mail/user with 0 bytes length is still created. Is this normal? I use sendmail+procmail+dovecot. I have also tried the combined procmail+deliver approach with the same results. I also use a global /etc/procmailrc. Thank you

Hi all, ok, I am updating to the 2.0 way of doing things and have managed to get everything set up right, except I am getting the following errors when attempting to use managesieve with our webmail client (roundcube) that I didnt get when using dovecot 1.2.11...

[Dovecot] convert Plugin Error

[Dovecot] Ubuntu upgrade to 10.04 --> dovecot no longer working
by HenkR 14 Jun '10

14 Jun '10

Hi, Last year I installed dovecot on my Ubuntu V9 system 64 bit system. I use it to store emails from several clients in the LAN using IMAP. Last week I upgraded to Ubuntu 10.04. Now Dovecot is no longer working. It started with messages about sieve, so I disabled sieve in the configuration file (did not use it in the past, don't know what it is). Dovecot can now be started without errors or warnings, but I cannot connect in the client. I get a message saying "could not connect to server: connection refused". Can anybody help? kind regards, Henk -- View this message in context: http://old.nabble.com/Ubuntu-upgrade-to-10.04---%3E-dovecot-no-longer-worki… Sent from the Dovecot mailing list archive at Nabble.com.

http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta6.tar.gz http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta6.tar.gz.sig Unfortunately this still isn't rc1 yet, but the next one will be, I promise :) Basically all of the important changes are done now. The TODO list for rc1 is: - Test and fix dsync bugs - Finish director - Add man pages started by Pascal Volk. BTW. He asked for some feedback about them, but got only one reply: http://dovecot.org/list/dovecot/2010-June/049438.html I've also read through and answered nearly all of my email backlog. If you haven't gotten a reply, resend the mail. Some changes since beta5: - Added director: http://blog.dovecot.org/2010/05/new-director-service-in-v20-for-nfs.html - IMAP: Added STATUS (X-VSIZE) command for easily getting mailbox's virtual size. - Lots and lots of doveadm improvements and new commands - Postlogin scripts now need to be executed using "script-login", not "script" binary. - Quota warnings are executed now asynchronously using the new script binary. See http://hg.dovecot.org/dovecot-2.0/rev/a179fcbbf960 - Added passdb static for proxying and similar configurations - TLS SNI configuration must now be done using local_name {} blocks, not local {} - lib-storage plugin API changes, external plugins must be updated to work correctly - Lots of fixes

[Dovecot] Shared Mailbox Questions
by Chris Hobbs 11 Jun '10

11 Jun '10

Hi All, I've pored over the wiki, read through the archive, and have what I believe should be a working set-up, but I can't seem to get my shared namespace to work correctly. Any guidance would be much appreciated. I started off using a flat file for acl_shared_dict and ran into the same problem recently reported with the shared-database file getting chown'd to the first user to touch it with 0600 permissions. So I thought I'd give it a whirl with sqlite. Here are the (hopefully) relevant bits from dovecot -n (the entire output is posted below). This is dovecot 1.2.9 running on a freshly installed ubuntu 10.4 server: namespace: type: shared separator: / prefix: shared/%%u/ location: maildir:/home/staff/%%n/Maildir:INDEX=~/Maildir/shared/%%u list: children plugin: acl_shared_dict: proxy::acl dict: acl: sqlite:/etc/dovecot/acl-shared-dict.conf acl-shared-dict.conf looks like this: connect = /home/staff/dovecot/acl-shared-ns.sqlite map { table = acl_shared_ns pattern = shared/shared-boxes/user/$to/$from value_field = has_visible_folders fields { from_user = $from to_user = $to } } /home/staff/dovecot/acl-shared-ns.sqlite is set 0666, and I can add records to it from the sqlite command line as a normal user. The table was created with: CREATE TABLE acl_shared_ns (from_user, to_user, has_visible_folders, PRIMARY KEY (from_user) ON CONFLICT REPLACE); When I attempt to SETACL from a telnet imap session, I get the following errors in mail.err: Jun 9 22:10:23 imap2 dovecot: dict: dict sql iterate failed: file is encrypted or is not a database Jun 9 22:10:23 imap2 dovecot: dict: dict sql iterate failed: file is encrypted or is not a database Jun 9 22:10:23 imap2 dovecot: dict: sqlite: exec(INSERT INTO acl_shared_ns (has_visible_folders,to_user,from_user) VALUES ('1','chobbs','IOchoa')) failed: file is encrypted or is not a database (26) Jun 9 22:10:23 imap2 dovecot: IMAP(IOchoa): read(/var/run/dovecot/dict-server) failed: Remote disconnected Jun 9 22:10:23 imap2 dovecot: IMAP(IOchoa): acl: dict commit failed Jun 9 22:10:23 imap2 dovecot: dovecot: child 8268 (dict) killed with signal 11 (core dumps disabled) Running that same "INSERT INTO..." as the IOchoa user from the sqlite command line works just fine. At this point any further deleteacl or setacl commands simply hang, presumably because there's no longer a running dict process.

[Dovecot] question about rpc quota reporting 1.2.11
by Tom Lieuallen 11 Jun '10

11 Jun '10

Timo, thank you for the reply to my question about shared folders yesterday. I'm now trying to get quota reporting working consistently. This is with dovecot 1.2.11 in solaris 10 sparc. We have local quotas for the mail spool (/a1) and quotas for home directories. All are UFS and have rpc (rquota) working fine. With just this: protocol imap { mail_plugins = quota imap_quota } My mail client (thunderbird 3.0.4) reported the home directory quota. So then I added this: plugin { quota = fs:INBOX:mount=/a1 quota2 = fs:Home:mount=%h } First, I had to make /a1/quotas world readable, otherwise I'd get this error: open(/a1/quotas) failed: Permission denied I'm getting the same type of error with the quota2 line now: open(/nfs/rack/u4/quotas) failed: Permission denied Since the home directory quota worked without the plugin configuration, my guess is that the plugin config is not using rpc. I can't find any way to force it to use rpc. Again, if I make that 'quotas' file world readable (which I believe isn't good practice), dovecot stops complaining. Also, what should I expect to see on the client? Will dovecot report only one quota (the one that's closer to the limit), or will it report both? I've only seen the first quota in thunderbird, but that could easily be a client issue. thank you Tom Lieuallen Oregon State University

[Dovecot] null errors from 2.0.beta5
by Mike Abbott 11 Jun '10

11 Jun '10

When my dovecot-2.0.beta5 auth module logs a 552-byte debug message, the message is split into two lines and also a null error message: Wed Jun 9 23:44:29 gromit dovecot[58892]: auth: Error: I think this has to do with the use of PIPE_BUF (512) sized buffers in the logging code, and the !line_is_ok() case in i_failure_parse_line(). Could you please remove the null error message? Just a nuisance, nothing serious. Thanks.

[Dovecot] lazy-expunge acl bug?
by Martin Ott 11 Jun '10

11 Jun '10

Hi, we've defined a public namespace "shared" and use the acl and lazy-expunge plugins among others. The problem is, that a mailbox is deleted by the DELETE-command without the x-flag to be set (# 1.2.9): a myrights shared/aclDeleteTest * MYRIGHTS "shared/aclDeleteTest" lrsed a OK Myrights completed. b delete shared/aclDeleteTest b OK Delete completed. c myrights shared/aclDeleteTest c NO Mailbox doesn't exist: aclDeleteTest This behavior should be different and the mailbox should not be deleted, should it? Is there a fast workaround? Without the e-flag, mailboxes can't be deleted. But as some users should be allowed to use the expunge operation, it's no option to remove the e-flag... thx Martin

[Dovecot] problems with shared mailboxes and other general issues
by Tom Lieuallen 11 Jun '10

11 Jun '10

I'm also having beginner's troubles with shared mailboxes with dovecot 1.2.11. I've used the TestInstallation instructions for connecting to the imap port via openssl and issuing the setacl/getacl commands. Those appear to be fine. I'm having real difficulty with the acl_shared_dict configuration. I'd prefer to just use a flat file, as I don't anticipate using shared folders very frequently. I don't need a database and would greatly prefer not to have a dependency on our database service. So, with this setting: acl_shared_dict = file:/private/dovecot/var/etc/shared-mailboxes The '../var/etc' directory is something like 755. I have to create the file first and make it 666. When it is updated, ownership & permissions are changed such that the user giving acl permissions then owns the file and it's 600. I tried setting it back to 644 afterward, so other users could read it, but they tried setting a lock in that dir as well. I tried this: acl_shared_dict = file:/private/dovecot/var/etc/shared-list/shared-mailboxes-%u Then I made shared-list have '1777' permissions. Permissions-wise, this will now work, including locks, but I'm guessing this is just plain wrong and I still can't verify access. My second choice was to use sqlite for this acl_shared_dict, but, even though I compiled dovecot with sqlite support and 'ldd' shows that '../libexec/dict' is linked against sqlite libraries, when I tried this config: acl_shared_dict = sqlite:/private/dovecot/etc/acl-shared-dict.conf I get this, and dovecot fails to start up. EUnknown dict module: sqlite I question whether I can use sqlite for acl_shared_dict. Furthermore, in this vein, I don't really know what the shared namespace should even look like. I've been trying the imap commands LIST and MYRIGHTS to verify access, but there are simply no examples. I'd rather expect this to work: x myrights shared/fromuser/folder but all I get is mailbox doesn't exist. I know 'shared' is the namespace, but I just don't know how it should really be referred to. Personally, I can live without the acl_shared_dict (from what I understand). I don't need to see the shared path for subscription, I'd just manually add the folder path to the .subscriptions file for the handful of users that need it. I just don't think it's working, though. On a related note, I thought I'd increase debugging to see if that helped out any. When I change 'mail_debug' to 'yes', as soon as I issue the imap login command, it logs some stuff, then kicks me out. Jun 09 15:57:53 IMAP(tom2): Info: acl: initializing backend with data: vfile Jun 09 15:57:53 IMAP(tom2): Info: acl: acl username = tom2 Jun 09 15:57:53 IMAP(tom2): Info: acl: owner = 1 Jun 09 15:57:53 dovecot: Error: child 6000 (imap) killed with signal 11 (core dumps disabled) I would assume this error is causing my problems, but for all I know, it could be a side-effect of verbose debugging -- to just terminate. I see nothing about that in the docs, though. imap works fine without verbose logging, so I'm baffled. I have been frustrated by the shared namespace documentation. I've been through it again and again, but haven't found the answers I've been looking for. Here is the relevant configuration: namespace shared { location = mbox:%%h/mail/shared:INDEX=%%h/mail/shared/.imap # everything else defaults } protocol imap { mail_plugins = quota imap_quota acl imap_acl } protocol lda { mail_plugins = acl } plugin { acl = vfile acl_shared_dict = file:/private/dovecot/var/etc/shared-list/shared-mailboxes-%u }

[Dovecot] Question about directory hashing
by Javier de Miguel Rodríguez 11 Jun '10

11 Jun '10

Hello I have been reading http://wiki.dovecot.org/MailLocation and http://wiki.dovecot.org/Variables and I do not fully understand the directory hashing feature. I want to migrate > 70.000 users from Sun Messaging to Dovecot using imapsync. I have tested with mail_location=maildir:/buzones/us.es/%1Hu/%2.1u/%n but I get the following directory tree: `-- 0 |-- - |-- 1 |-- 2 |-- 3 |-- 8 |-- _ |-- a |-- ab |-- b |-- c |-- d |-- e |-- ev |-- f |-- g |-- h |-- i |-- ie |-- is |-- j |-- jb |-- jj |-- jp |-- js |-- k |-- l |-- m |-- mb |-- n |-- o |-- p |-- pp |-- q |-- r |-- rm |-- s |-- t |-- u |-- v |-- w |-- x |-- y `-- z The ideal directory layout should be the following: First directory level: Letters from a to z Second directory level: Numbers from 0 to 200 Third directory level: %n (username without @domain) How can I achive this directory layout (or other optimized for 70.000 users) . I use ext3 on Red Hat Enterprise Linux 5 with directory indexes on. Regards Javier de Miguel

[Dovecot] Fail2ban

I have fail2ban working for EVERYTHING else except dovecot. I have tried using my own custom regex in conjunction with the regex on the dovecot.org site. Neither are picked up by fail2ban and I'm trying to use an imminent attack agaist dovecot, going on now, to my advantage to see when I get the right regexp. Here are my current ones: failregex = .*dovecot: (?:pop3-login|imap-login): (?:Disconnected|Aborted login) $(?:auth failed, .* attempts|no auth attempts)$:.*rip=<HOST>,.* <<< this is my custom (?: pop3-login|imap-login): (?:Authentication failure|Aborted login \(auth failed|Aborted login \(tried to use disabled|Disconnected \(auth failed).*rip=(?P<host>\S*),.* <<< from dovecot.org .*warning:.\S*\[(?P<host>)\]: SASL.(?:PLAIN|LOGIN).authentication failed:.* Here is the current attack: Jun 10 17:18:10 mail dovecot: pop3-login: Disconnected (auth failed, 1 attempts): user=<rahul>, method=PLAIN, rip=113.12.82.71, lip=173.50.101.12 Can someone help me out a little? Thanks, Jerrale G

[Dovecot] Evolution and Thunderbird do different things?
by Phil Howard 10 Jun '10

10 Jun '10

I'm trying both Evolution and Thunderbird on my IMAP server, and find that there are differences in how some things are done, between clients. Shouldn't there have been a standard way to do these things in the IMAP protocol? The first thing I noticed is that when deleting email from one client, it puts a "T" on the file name, leaving it where it is, and from the other client, it moves the mail to a ".Trash" directory on the server (and created a 2nd "Trash" folder ... so now I have 2 "Trash" folders, one with some deleted mail in it, and the other with some deleted mail in it). I'm not saying Dovecot has a problem here. But maybe IMAP the protocol does for not having a standard way to do things, and these clients, for not doing it the same way (if there is some standard somewhere). Any IMAP experts here know what the story is with this?

[Dovecot] Problem with LDAP query
by Aleix Dorca 10 Jun '10

10 Jun '10

Hi people, first message to this list. I've a problem with dovecot 1.0.15 (debian latest package) and an LDAP query. The situation is the following. My LDAP users have multiple mail addresses (field 'mail') and mail should be able to be sent to any of these and the mail should always end on the user's mailbox. This is not working for me now. My dovecot-ldap.conf relevant config shows: user-attrs = uid=user user_filter = (&(objectClass=posixAccount)(|(uid=%n)(mail=%u))) This correctly detects multiple addresses but mail always end in folder (from dovecot.conf): mail_location = maildir:/home/vmail/%n/Maildir So if user@domain gets a mail it ends in /home/vmail/user/Maildir but if the same user gets an email to user-alt@domain it ends in /home/vmail/user-alt/Maildir instead of /home/vmail/user/Maildir. I've been debugging and I get this on my mail.log file: Jun 10 12:41:29 horologium deliver(user-alt@domain): auth input: user-alt@domain Jun 10 12:41:29 horologium deliver(user-alt@domain): auth input: user=user Jun 10 12:41:29 horologium deliver(user-alt@domain): auth input: uid=5000 Jun 10 12:41:29 horologium deliver(user-alt@domain): auth input: gid=5000 Jun 10 12:41:29 horologium deliver(user-alt@domain): maildir: data=/home/vmail/user-alt/Maildir Jun 10 12:41:29 horologium deliver(user-alt@domain): maildir: root=/home/vmail/user-alt/Maildir, index=/home/vmail/user-alt/Maildir, control=, inbox= Since I'm in version 1.0.15 can't use the mailLocation with the $ substitution. Anyway, any help will be appreciated.

[Dovecot] converting from vm-pop3d
by Tim Uckun 09 Jun '10

09 Jun '10

Hello All. I am looking into an old server which is running vm-pop3d. This server is having problems because the pop3 server is taking up 100% of the CPU. I looked at the largest mailboxes and there are a handful over 20 megs in size, the largest one is 55megs, they are all mbox format (I think). I have been looking at the wiki and it looks like there is a perl script to make the mailboxes behave. There are also other scripts that try and convert mbox to maildir formats and from what I can gather dovecot can do this as well. Finally the dovecot in the fedora repos is 1.0.X and I notice that the latest in 1.2.X is there a more up to date dovecot RPM repo? I would appreciate any advice anybody can give me on how to proceed with this transition. Thank you in advance.
