[Dovecot] Newbie index infrastructure and location questions
by Stewart Dean 15 Mar '07

15 Mar '07

I've been lurking for a year or more and am now actually bringing Dovecot up (it seems that any time I make a serious effort at this, something else falls in the pot and I have to give it up yet again). Index questions: I understand the indices should be placed in a non-file-system-quoted place. I have in mind to create /var/dcndx 1) Roughly how much space do indices take up (so I can size space for a directory for them)? I have 4000 users, average mbox inbox size is 5.5MB (totalling 22GB), the number of messages/user mailbox I'd guess to average around 100 and go as high as 5000. They have maybe as much as 3x times space and messages in folders, though I guess the average is about half that of INBOX 2) I'm clear that DC will automagically create the index files, but a) do I have to create a subdirectory for each user, ex: /var/dcndx/user1 b) Is there one index file theat handles a user's mailbox and folders or a separate one for each? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Newbie NFS question
by Stewart Dean 15 Mar '07

15 Mar '07

As is usually the case, I'm not sure enough of what the DC docs are referring to; there are some implicit info assumptions that I, the Newbie, miss... Anyway, here is my situation Dovecot is to run on one machine only, its index files are stored in on a separate, non-quotaed, not NFS filesystem. INBOX and folder filesystems (all mbox format) are native to this machine and are NFS exported to three machines with root access. NFS access can be NFS V2, or 3 or 4. 1) a user maintenance server that may add or delete users and their INBOXES/folders 2) a mailing list server that writes mailings email to the NFS mounted file system of user INBOXes 3) A user login machine where the users may access their INBOXes and folders All machines are running vanilla IBM AIX; I have never known there to be corruption from NFS locking problems, and am not aware of any locking/caching parameters for AIX's NFS implementation. All machines are running NTP synched to a common NTP master server My questions: 1) Since my index files are stored in on a separate, non-quotaed, not NFS filesystem, can I correctly assume this means I can ignore the nmap_disable and lock_method parms? 2) The docs say: > The easiest way to get better performance without caching problems is > to just make sure the user is always redirected to the same server. If > you can manage to do that, then it's safe to enable attribute caching. The INBOXes and folders live on the mail server where a) DC is going to run and b) they are exported to the three other machine. Does this mean that I don't have to mess with actimeo? 3) Pardon my ignorance....Is actimeo set on the NFS server as an attribute of exportation or on the NFS client on the imported FS...or both 4) Is there any reason related to data integrity or performance to prefer NFS V2 or 3 or 4? 5) Are there other questions I should ask of IBM about NFS client and Server daemon config Thanks in advance........... -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] quota - dict - username = '(null)'
by Andreas Jørgensen 15 Mar '07

15 Mar '07

I am trying setting up at virtual domain with quota using postfix and dovecut. But I can't get the quota to work, every time I try sending a mail the following queries is run on the database. SELECT home, uid, gid FROM mail_view_tmp WHERE account = 'dummy' AND domain = 'example.com' SELECT current FROM mail_quota WHERE path = 'quota/storage' AND username = '(null)' BEGIN;INSERT INTO mail_quota (current, path, username) VALUES ('quota/ storage', 262, '(null)') ON DUPLICATE KEY UPDATE current = current + 262;COMMIT The mail is delivered, but the quota for the user is not updated. Instead I just have an other new row for the user (null). I am using the package dovecot-1.0.rc2p3-mysql on OpenBSD 4.0 for macppc My configuration: (posting the full content of alt the config files seemed unnecessary so I cut out the important bits) /etc/postfix/main.cf ... virtual_transport = dovecot /etc/postfix/master.cf : ... dovecot unix - n n - - pipe flags=DRhu user=vmail argv=/usr/local/libexec/dovecot/deliver -d $ {recipient} /etc/dovecot.conf .... protocol lda { mail_plugins = quota } .. auth default { user = root passdb sql { args = /etc/dovecot-mysql.conf } userdb static { args = uid=2000 gid=2000 home=/var/vmail/%d/%n/ } socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = vmail group = vmail } } } dict { quota = mysql:/etc/dovecot-dict-quota.conf } plugin { quota = dict:storage=10240:messages=1000 proxy::quota } /etc/dovecot-mysql.conf: driver = mysql connect = host=localhost dbname=ingoBase user=dovecot password=dovecot default_pass_scheme = CRYPT password_query = SELECT password FROM mail_view_dovecot WHERE account = '%n' AND domain = '%d' user_query = SELECT home, uid, gid FROM mail_view_tmp WHERE account = '%n' AND domain = '%d' or account = '%u' /etc/dovecot-dict-quota.conf connect = host=localhost dbname=ingoBase user=dovecot password=dovecot table = mail_quota select_field = current where_field = path username_field = username Is there something wrong in my configuration or is this a bug in the version i am using ?

Does this still happen? No, however I haven't had to touch our Dovecot proxies in several months. They just work. We're still running a copy I pulled from CVS just before 1.0.rc8. We're running the new code only on our backend mail servers. I guess we should update our proxies soon. Bill

[Dovecot] Courier keywords - anyone even tried?
by Troy Engel 14 Mar '07

14 Mar '07

I do realize from the Wiki that the formats are incompatible, and am looking at the Courier spec (http://www.courier-mta.org/imap/?README.imapkeywords.html) and the Dovecot spec (http://wiki.dovecot.org/MailboxFormat/Maildir) trying to see if there's any sane way I could try and write a shellscript. The pain here is the Courier spec, I think I lost a few brain cells trying to understand this convoluted methodology ("When encountering ".N.file" after another ".N.file" was encountered earlier, remove the file with the lesser N, unless the larger of the two Ns is greater than or equals to T." e.g.) Has anyone even started down this path and has some prototype code written that they gave up on? Is this just so painful trying to migrate that I should just give up? Any ideas welcome... -te -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com

[Dovecot] Benchmarking CVS HEAD vs. v1.0
by Timo Sirainen 14 Mar '07

14 Mar '07

Some new features in CVS HEAD are: - v1.0 saves most of the data to dovecot.index.cache only when the client is FETCHing the messages. With mboxes the message headers are saved while parsing the mbox, which is almost the same thing. With CVS HEAD the dovecot.index.cache file is updated already when the new messages are being saved (with deliver or IMAP APPEND). This avoids reading the message second time (although if client fetches the new message bodies immediately it doesn't probably help that much). - Mailbox list index. LIST command can be handled by reading the mailboxes from the index. The index also contains the mailbox's message counters, so STATUS command can be handled by only looking into the index file. - Multiple commands can be handled simultaneously. For example you can start a long running SEARCH command and then at the same time continue FETCHing new messages. Or if you're doing a long FETCH (eg. fetching all message bodies) you can do a smaller FETCH while the long one is still running, and get the result in the middle of the long running FETCH reply. There are also indexing support for SORT and THREAD, and full text search indexes for SEARCH BODY/TEXT, but I didn't benchmark these now. It looks like CVS HEAD is quite a lot faster than v1.0. I think that's mostly because of the APPEND optimization. Here are the results: 100MB ext3 filesystem inside a file in XFS.

It is still disconnecting with "Connection queue full", although less frequently. Testing with about 315 IMAP connections right now and same config as earlier today, so it should never hit this condition, right? The weird thing is sometimes when I am testing via telnet, my session encounters this condition and disconnects within the first 5 seconds. It does this with and without these patches. Bill

Postfix and dovecot get their User information from mysql tables that are administered with postfixadmin. Mail is filtered through clamav and spamassassin using amavisd-new setup as a content filter. All users mail is delivered such as their maildir is /usr/local/vmail/%d/%u using dovecot's lda 'deliver' agent. The system is working fine as configured.. Mail goes where it is supposed to.

Hi! I discovered a bug in $subject. Next line caused a compilation error: auth_request_log_debug(auth_request, "vpopmail", "lookup user=%s domain=%s", vpop_user, vpop_domain); I think, te correct version is: auth_request_log_debug(request, "vpopmail", "lookup user=%s domain=%s", vpop_user, vpop_domain); -- Gabor HALASZ <halasz.g(a)freemail.hu>

[Dovecot] Variable %h not recognized in userdb_mail (passwd-file)
by Michal Soltys 14 Mar '07

14 Mar '07

As in subject, if you for instance create a simple passwd-file with: test@domain.tld:{plain}pass:20000:10::/home/regular/.test::userdb_mail=maildir:%h/maildir Dovecot (rc23 & 27) will expand %h to empty string, and try to make a directory under / Mar 14 14:25:28 rasengan dovecot: IMAP(test(a)domain.tld): mkdir(/maildir/cur) failed: Permission denied Mar 14 14:25:28 rasengan dovecot: IMAP(test(a)domain.tld): mkdir(/maildir/.Trash/cur) failed: Permission denied ... If tilde is used instead of %h, the expansion works properly. While checking it, I tested other variables (putting aside craziness of using some of them), so summing it up - h,w,i,a,b don't work, all the other ones do. In case %h is not actually intended to work in passwd-files, some wiki examples would have to be adjusted.

[Dovecot] Issue with pop3 & phpList
by Chris Harner 14 Mar '07

14 Mar '07

Hello, all. Dovecot really sparked my interest when I noticed it focused on security. It seems to be a great product thus far. Anyway... I'm new to the mail world (pop3/smtp), and I have a project in which I use a mass mailer known as phpList. If you aren't familiar with it, it has the ability to view and process bounces. Bounces are basically emails that don't quite make it (for the most part). In order for this to work, I must create a pop3 account. I installed Dovecot and now the port is open, which means the service is running. Here is where it gets confusing... When I goto process the bounces, it times out because of the fact that there were too many login attempts. Does dovecot have a default username/password? How do I set up a username and password? Is there a special way to just have the pop3 portion of Dovecot load? I went through the config file and took out some of the #'s like the docs said. Thanks!

So forget about memory, it was only my guesswork about your native language :) The lesson here: please translate all messages to English if you want to post to an English mailing list. Otherwise some people (like me) have no chance to understand just guessing ... :) -- - Gábor

[Dovecot] help with basic setup

14 Mar '07

I am new to dovecot and would like to setup dovecot with mysql auth. I successfuly installed postfix admin and used the default table structure there, Mail delivery works fine as It gets delivered to mailboxes. My problem is the login, dovecot runs with no errors but I get the error: Mar 14 14:39:43 itecsouth dovecot: auth-worker(default): mysql: Connected to localhost (postfix) Mar 14 14:40:34 itecsouth dovecot: pop3-login: Disconnected: rip=41.xxx.xxx.190, lip=41.243.140.153 Mar 14 14:41:14 itecsouth dovecot: pop3-login: Login failed: Plaintext authentication disabled: rip=41.xxx.xxx.190, lip=41.xxx.xxx.153 Mar 14 14:41:14 itecsouth dovecot: pop3-login: Disconnected: rip=41.xxx.xxx.190, lip=41.xxx.xxx.153 I have tried to change the pass scheme in dovecot-mysql.conf to CRYPT as but says unknown auth_scheme a copy of my dovecot.conf protocols = pop3 listen = * login_process_size = 64 default_mail_env = maildir:/usr/local/virtual/%d/%u/ mail_extra_groups = postfix verbose_proctitle = yes first_valid_uid = 125 first_valid_gid = 125 mbox_read_locks = fcntl mbox_write_locks = fcntl protocol pop3 { pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ auth_debug = yes auth_verbose = yes auth default { passdb sql { args = /usr/local/etc/dovecot-mysql.conf } userdb sql { args = /usr/local/etc/dovecot-mysql.conf } } -- and the dovecot-mysql.conf # Database driver: mysql, pgsql driver = mysql default_pass_scheme = PLAIN connect = host=localhost dbname=postfix user=dovecot password=dovecot password_query = SELECT password FROM mailbox WHERE username = '%u' AND active = '1' user_query = SELECT maildir, 125 AS uid, 125 AS gid FROM mailbox WHERE username = '%u' AND active = '1'

It has Dovecot 1.0rc2. I now see there have been 25 rc's since then. (Yikes!) So I guess I should be complaining upstream. I did search the net for several weeks, however, and found no mention of this problem, even in the Dovecot wiki or mailing list archive. So if you say it's fixed, then I'll put something in the wiki to that effect and go badger the Ubuntu guys for an upgrade. :-) Cheers, Tudor.

I think I configured Mailman to drop all text/html MIME parts. Lets see if it works. html -> text translation is also enabled.

[Dovecot] Dovecot for "push email"
by Matthew Sheffield 14 Mar '07

14 Mar '07

Does anyone have experience here using a combination of Dovecot and a Windows or Palm client that supports IMAP IDLE to achieve "push email?" I'm doing some research into how feasible this is for companies and non-profits.

[Dovecot] imaptest updates
by Timo Sirainen 13 Mar '07

13 Mar '07

I spent the last 5 hours or so updating my imaptest tool. It's beginning to become almost like a real IMAP client. http://dovecot.org/tools/imaptest10.c contains a version that compiles against Dovecot v1.0 (instead of against CVS HEAD). imaptest is this tool that I've been using for a few years to do stress testing. It can create a lot of dummy IMAP client connections which execute some commands. Today I added some new features to it: - Support for pipelining commands (where allowed by IMAP spec). Looks like it about doubles the throughput. "no_pipelining" option disables this. - Support for MULTIAPPEND extension. When multiple mails are APPENDed one after another this extension is used to save them all in one transaction. - Previous versions gave an error when trying to append large mails. Now large mails work too. - By default the commands are executed in one specific order. Using "random" option randomizes the order. - You can separately specifify probabilities of how often to execute each command. 0 means never, 100 means always, 10 means 10% of the time and so on. 100,30 means that it's always executed, and then it's executed again and again with 30% probability. The basic way to run it is: ./imaptest user=test pass=password host=imap.domain.org mbox=/home/user/mail/dovecot clients=1 Or if you want to run multiple users, you can use user=test%d which will use users test1..test100 (the size is hardcoded in USER_RAND define). If you want to do benchmarking, you can set it to run for specified amount of time, and you should also give random number generator the same seed every time: ./imaptest seed=123 secs=300 If you want to test/benchmark only the login+logout speed, use: ./imaptest - select=0 To create a lot of long-running clients doing STATUS and NOOPs: ./imaptest clients=100 - logout=0 status=50 noop=50 delay=100 To test copying messages: ./imaptest copybox=Trash By default LOGIN command is used. If you want to try AUTHENTICATE: ./imaptest auth=100 Hmm. I guess that's about it. The list of commands that you can use starts from line 134. You can use either the long names or the short names.

[Dovecot] Timed Out or Disconnect Errors on emails with attachments
by Tudor Holton 13 Mar '07

13 Mar '07

Hello all, I've migrated our Maildir system from Courier-IMAP-SSL to Dovecot with SSL and now we're getting "Connection to <server> Timed Out" errors when sending mail with attachments. The mail gets sent, however it doesn't save the mail in the user's "Sent" folder. Our IMAP and SMTP servers are different. So the client sends to the SMTP server first, completes that, and then opens a channel to Dovecot and dovecot appears to receive the data (TB gives a progress bar as it's sending to dovecot) and then disconnects _after_. We have a mixed bag of clients here from Thunderbird on Linux and Windows, through Outlook Express to Outlook. All show similar errors. I enabled the logs on dovecot, however it wasn't very informative. At the time it occurred the only line in the log file was: dovecot: 2007-03-13 16:21:12 Info: IMAP(tudor): Disconnected This is obviously different from "Disconnected: Logged out". Emails without attachments behave ok, it only occurs with emails with attachments. Has anyone else had any experience of this? Cheers, Tudor.

[Dovecot] Prayer, Maildir and Folders whose names begin with "."
by Mike Brudenell 13 Mar '07

13 Mar '07

Greetings - I think I've just had one of my fears confirmed: not Dovecot-specific exactly, but it affects how we will use of Prayer (Webmail Software) with Dovecot... Currently our production service uses MBX-format mailboxes with the UW IMAP server; we also use the University of Cambridge "Prayer" software for Webmail. By default Prayer saves its preference settings, address book and so on in a regular IMAP folder called ".prayer" And one of the nice things about the UW IMAP server is that you can tell it not to include files whose names start "." when returning the list of folders for a LIST command. This means: * People don't see the secret ".prayer" folder when they look at the list; * But if something (eg, Prayer) knows its name it can open this folder to get at its content. The combination of these is that (a) Prayer can store its settings and (b) users don't see where, so can't open/tamper with the secret settings folder for Prayer. But I've just discovered that I can't create a folder called ".prayer" using Maildir-format mailboxes. The problem appears to be the leading "." I suspect it's because the Maildir++ specification at http://www.inter7.com/courierimap/README.maildirquota.html says this: > Folders are created as subdirectories under the main Maildir. The name of > the subdirectory always starts with a period. For example, a folder named > "Important" will be a subdirectory called ".Important". You can't have > subdirectories that start with two periods. A folder named ".prayer" would lead to a subdirectory being created called "..prayer" I think. Q. Can anyone confirm that you can't create Maildir folders called ".somename"? Q. Are there any other Prayer users out there using Dovecot and Maildir format mailboxes? What are you doing about the user-settings folder for Prayer? (And do you manage to hide it from view, so they can't tamper with its contents?)

[Dovecot] index performance issues
by Netserve 13 Mar '07

13 Mar '07

Running 1.0.rc22 We have a single file server, running NFS (Single large sas disk) with about 80Gb of mail. mount -o remount,rsize=2048,wsize=2044,actimeo=0,soft,rw xx.xx.xx.xx:/mailboxes /nfs1 There are 3 front end pop/imap servers using an LVS director. Indexes are stored on each front end server. -rw------- 1 admin 500 144 Mar 12 17:47 dovecot.index -rw------- 1 admin 500 10272 Mar 12 17:47 dovecot.index.cache -rw------- 1 admin 500 120 Mar 12 17:47 dovecot.index.log Normally everything runs fine, there are about 1500 active pop accounts and 100 Imap. Typically, 10 to 20 pop accounts are downloading at anyone time, and there may be 10 or 20 active Imap sessions. If we find that the index partition has got to 100% full and corrupted the indexes then we'll delete the entire index dir and let dovecot rebuild all the indexes however, we end up with 100mbit / 10Mb/sec of network traffic between the NFS server and the pop/imap servers. The nfs server load climbs to 20+ as does the load on the front end mail servers. It can take 4 or 5 hours for the indexes to rebuild during which time imap is slow but works and pop downloads all end up with dead processes that need clearing every few minutes. admin 5869 0.0 0.1 4384 1060 ? D 17:56 0:00 \_ pop3 [info@.co.uk 180.98] admin 5877 0.0 0.1 4392 1112 ? D 17:57 0:00 \_ pop3 [bro94 62.182] admin 5879 0.0 0.1 4396 1052 ? D 17:57 0:00 \_ pop3 [spamcatch@.com 81.163] admin 5884 0.0 0.1 4392 1056 ? D 17:57 0:00 \_ pop3 [ctaylor@.com 81.175] Normally the nfs server delivers possibly 200Kbytes of traffic average spiking to 400Kbytes but the 900+Kbytes per second sustained rate for 5 or 6 hours is killing the service. Is there something we've got wrong here? (I know a Scsi raid NFS would help as would Gbit networking but I can't see the setup we've got as needing that sort of hardware spec?) Thanks John

[Dovecot] imap + unmounted home disk
by T. Horsnell 13 Mar '07

13 Mar '07

dovecot 0.99 still (RHEL4), I'm sorry to say. The config is for mbox's to live on the user's home disk. If the user tries to make an imap connection when his home disk is unmounted, various permission denied messages are logged, as expected, but then the imap process seems to hang around instead of aborting. The result is that eventually the imap process limit is reached, and even those users whose home disks are correctly mounted, cant get at their mail. Apologies if this has already been fixed - I cant find anything relevant in the archives. Cheers, Terry

[Dovecot] Password encoding
by David Mills 13 Mar '07

13 Mar '07

Hi, I've currently got a problem authenticating to my dovecot server (1.0rc15). The server is set up to authenticate against a mysql server, with a default password scheme of 'crypt'. The problem is that some of the passwords I need to transfer (all from /etc/shadow files) are md5 encoded, and when I put {md5-crypt} in front of the password to force the scheme, dovecot answers :"Unknown password scheme md5-crypt". If anyone has any ideas, I'd really appreciate it. TIA for your time.
