[Dovecot] Public Namespace + ACLs + virtual users
by Fintec 28 Apr '08

28 Apr '08

g'day! I'd just like to share my experience with public namespace and ACLs. I know this has been discussed a number of times in the past, but there were no definite answers. dovecot version i'm using: 1.0.13 Got a public namespace setup in dovecot.conf as follows: namespace public { separator = . prefix = Public_Folders. location = maildir:/home/vmail/domains/% d/Public_Folders:CONTROL=/home/vmail/domains/%d/% n/Public_Folders/support:INDEX=/home/vmail/domains/%d/% n/Public_Folders/index hidden = no } In it's own right this works just fine and it's been in use for some time now. But we need some control over who can access and delete things. So I had a go at configuring ACLs. I configured global ACLs, because as far as I can tell, per directory ACLs seem to be ignored. Once configured global ACLs work fine, except for 1 major issue; users cannot create new folders because ACLs do not get propagated (are not applied to the subfolders). If an user attempts to create a new (sub)folder, the folder is created on the filesystem however email client throws an error and the folder is inaccessible to the user as there is no ACL for it. Any pointers how to get around this? Has this been dealt with in v1.1? Regards Natko Muzina

[Dovecot] antispam for Dovecot 1.1
by Anders 26 Apr '08

26 Apr '08

Hi Johannes. I wanted to try out the antispam plugin for a Dovecot 1.1 install, only to learn that 1.1 is actually not supported. Are there any plans to remedy this? If not, is it known how much effort is required? (i.e. could I do it myself?). Thanks, Anders.

[Dovecot] Does a script exist to fix broken maildir timestamps?
by drbob 26 Apr '08

26 Apr '08

Hello, When I upgraded to dovecot (changing servers at the same time) in November last year I copied the maildirs from my old server without using the -p option to preserve timestamps! Since my mail client displays the email dates based on the Date header rather than the imap "internaldate" I didn't notice the problem until today when I tried to migrate an account to gmail using imapsync and found that all emails prior to November display the wrong date in the web interface (they show the date they were copied in November). I feel very silly. Before I go try to hack together a script which parses all my older email files and changes the timestamps to the time recorded in the "Date:" header, does anyone know if robust, tested version of such a script is alrady available? Would correcting the timestamps in this way cause any problems for dovecot (e.g in the index files)? Thanks in advance for any help. drbob NB In my googling for a solution to this problem I found this hack to imapsync which would rewrite the "internaldate" based on the date header during a sync. Whilst I'd rather fix the timestamps that are the source of the problem, it may be useful for others finding this post in the future, see: http://www.zimbra.com/forums/installation/237-received-date-appears-incorre…

[Dovecot] Mixing LDAP and static
by Anders 25 Apr '08

25 Apr '08

I want to read quota size from LDAP, but I have a static value for home. How can I mix these? Right now, I have this LDAP configuration: user_attrs = uid=home=/var/mail/vhosts/%d/%n,gosaMailQuota=quota_rule=*:bytes=%$M which works fine, but looks up the uid attribute needlessly, and is not scalable: I have to pick a different, always-existing LDAP attribute for each static extra field that I want to set. Is there some LDAP configuration syntax like the SQL "SELECT '/var/...' AS home" ? Thanks, Anders.

[Dovecot] 1.0.5: many pop3-login processes?
by Alan Ferrency 25 Apr '08

25 Apr '08

Hello, We are running dovecot 1.0.5 on a test server, with FreeBSD 6.2 (though I have noticed the same problem since dovecot versions in the 0.99 range). We don't have very many simultaneous pop/imap users, but we have a proliferation of pop3-login processes. Currently we have 128 such processes. We have 11 imap-login processes, but only a few actual imap processes running. Is this normal? Can we stop it? Is anyone else successfully running dovecot on FreeBSD 6.2? Thanks for your help.

[Dovecot] Problem with Dovecot Delivery Agent, Extra "From" lines and mbox
by Hokan 25 Apr '08

25 Apr '08

When an mbox email contains a line that looks like a "Mail" header it should be quoted (per RFC 4155). Sendmail's delivery agent does this, as does Procmail delivery agent. Dovecot deliver does not do this. Example line, with ">" quote: >From hokan(a)hokan.org Thu Mar 8 17:28:01 2008 When reading email (IMAP) that contains such an unquoted line, the email abruptly ends before the "Mail" line. There may (or may not) appear another email (visible to the client) that contains the rest of the email. -- Hokan MEnet, a wholly owned subsidiary of Enet System Administrator Department of Mechanical Engineering hokan(a)me.umn.edu Institute of Technology 612.626.9800 University of Minnesota

[Dovecot] Authentication: Dovecot -> Vpopmail - > MySQL with one table per domain
by James Nordstrom 25 Apr '08

25 Apr '08

Hi All, I am using Dovecot 1.0.13 with Vpopmail (Qmail Toaster current) backed by MySQL with one table per domain (--disable-many-domains) . What I cannot figure out is how to have Dovecot authenticate to Vpopmail when Vpopmail uses one table per domain. Basically I need dynamic SQL in the Dovecot-sql.conf file. Currently I have: password_query = select pw_clear_passwd as password from domainname_com where pw_name = '%n' I need something like password_query = select pw_clear_passwd as password from %d where pw_name = '%n' Where %d is the name of the table. I can't use the exact domain name at it will not match the vpopmail format domainname_com. I would be happy to use some sort of sting builder but and not sure what my options are in the .conf file. Please help Thanks in advance James James Nordstrom Nordstrom Design Inc. E-mail: james(a)nordstromdesign.com US: 908-419-5597 Europe: 001/908-419-5597

[Dovecot] sieve header :matches for multiline header
by Anton Yuzhaninov 25 Apr '08

25 Apr '08

RFC3028 say: Folding of long header lines (as described in [IMAIL] 3.4.8) is removed prior to interpretation of the data. The folding syntax (the CRLF that ends a line plus any leading whitespace at the beginning of the next line that indicates folding) are interpreted as if they were a single space. But it seems to be not true for dovecot-sieve-1.0.2 for header Received: from example.ru (example.ru [192.168.105.14]) by myserver (Postfix) with ESMTP id D4DA5D85927 This sieve test work: header :matches "Received" "from *by myserver (Postfix) with ESMTP id *" But this test not work, while should also work according to RFC: header :matches "Received" "from * by myserver (Postfix) with ESMTP id *" -- WBR, Anton Yuzhaninov

[Dovecot] ACLs generating plugin problems.
by "Fábio M. Catunda" 25 Apr '08

25 Apr '08

Hi! I'm trying to use an ACL to avoid deletion of messages that are inside .Trash folder, the ACL is already working very well, the problem that I'm facing is that even if the message is not deleted, mail_log logs that it has been deleted. Also, in some cases part of the lazy_expunge code is executed too, but sometimes I just dont know where the message is, thats weird. I erased deleted and expunged folders, then I deleted a message, It hasn't been deleted, but "deleted" and "expunged" folders has been created. Anyway, I would like to know if there is a way to stop plugin execution when an ACL matches. Thanks a lot.

[Dovecot] alert function, V2
by Stewart Dean 25 Apr '08

25 Apr '08

I guess the alert function is not part of the spec, because it appears to be unimplemented in Dovecot, even though most clients implement it. Timo, I would hope this would be easy to implement, and it's functionality that will be valuable to every installation. Here's why. America recently had the tragedy of a shooting rampage on a large university campus (yes, America should do something about the violence and free access to guns in our culture/society). What was worse was that, due to the lack of an emergency notification process, some 20+ people died needlessly. Now all college and university administration are scrambling to set up emergency notification processes. Our first take on this is a massive all-hands mailing list, but a) best case, it would take 15 minutes (and as much as an hour) to get to everybody's mailbox. b) users would have to read through their mail and stumble on the message What's needed is an "in-your-face" unavoidable alert, and the UWIMAP alert functionality provides this. As I recall, you touch just about anything in your IMAP client and there's a popup message in the middle of the client IMAP window...and it happens repeatedly. We tried it back 3-4 years ago and found it too annoying to use. For this purpose, it's perfect. The wy UWIMAP did it, the presence of the file /etc/imapd.alert triggers it, and the text in that file is transmitted to the client. The message has to be short, a one-liner for a small popup window, but this could be a pointer to a shared system message folder. Of course, DC could sense the activation of the alert in some other fashion that the presence of a file. Ideally, whatever activates the alert function should be able to be turned on remotely; I had in mind to do it using a mail aliases that is a pipe to a executable...

[Dovecot] Rare problem with Indexes?
by richs＠whidbey.net 25 Apr '08

25 Apr '08

We've been running 1.1 rc3 now for about a month, and overall it's been very fast and stable. There is however an Index-related problem that keeps cropping up which prevents a user from accessing their mailbox until their Indexes are manually removed. Somehow, an Index becomes problematic, and Dovecot hangs forever when the mailbox is accessed. It manifests when a user logs in and issues a "SELECT INBOX", or "GETQUOTAROOT" when "maildirsize" needs rebuilding. When Dovecot hangs, no data is returned and no further commands are accepted, and the daemon must be killed. We see no errors in the logs, but have yet to catch the problem with "mail_debug" enabled. We're using NFS with Maildir's and these related options: mail_location = maildir:/mail/%Lu/Maildir:INDEX=/mail/%Lu/Cache mmap_disable = yes mail_nfs_storage = yes mail_nfs_index = yes mail_drop_priv_before_exec = yes mail_cache_min_mail_count = 128 mailbox_idle_check_interval = 5 maildir_stat_dirs = yes maildir_copy_with_hardlinks = yes maildir_copy_preserve_filename = no Has anyone else run across the need to purge Indexes manually? Could this be unrecoverable Index corruption, or a locking issue? We've made a copy of the mailbox when the problem occurs. However, when we test it later, Dovecot re-builds the "dovecot.index" file itself just fine, and functions normally. We plan to "mail_debug" when this happens next to see if we can get more information. Thanks! -Rich

[Dovecot] Dovecot features
by Phan Thanh Diện 25 Apr '08

25 Apr '08

Hi, We would like to switch from courier-imap to dovecot. I have installed dovecot on a machine running FreeBSD 6.3 and now testing it. My questions are below: 1. Can I configure dovecot to delete all files that are older, say 10 days, from defined mail boxes (for example Trash or Spam). 2. After I access mail box (using web mail squirrel imap) all emails moved from 'new' directory to 'cur'. Then messages are not accessible for pop3. Such behavor doesn't occur with courier-imap. Can I force dovecot to behave like courier-imap? Many thanks for help. Dien Phan

Hello.

[Dovecot] Dovecot timeout over NFS

Hi, I'm using postfix with Dovecot 1.0.5 and getting the following errors when a user moves a massive folders contents to trash (65000 or so messages): Apr 21 15:31:01 mink dovecot: IMAP(dev2(a)aluminati.net): Timeout while waiting for lock for transaction log file /virtual/store1/mail/d/dev2_aluminati.net/Maildir/.Deleted Items/dovecot.index.log Is there anything I can do to compensate for situations like this?

[Dovecot] Sieve script executed, but nothing happens

Hi all, I think I have almost solved my dovecot-deliver lookup problems, but now sieve still fails to work. From deliver's logfile I can tell the user's homedir is found and the sieve script is executed, but not as expected. My sieve testscript is very basic: /home/virtual/user.dovecot.sieve: ************* require "fileinto"; if address :is "to" "user@ mydomain.nl" { fileinto "sieve"; ( I also tried INBOX.sieve, without succes) } ************* But incoming messages for this account are still delivered in the normal inbox, not in the sieve folder.

[Dovecot] using mysql from within a plugin
by Alexander Prinsier 24 Apr '08

24 Apr '08

Hello, I'm trying to access a mysql database in a plugin. -What special compiler flags do I need? I discovered that when I don't explicitly link lib-sql/libsql.a in, then I get an undefind symbol error about sql_init when loading the plugin. Shouldn't the imap process itself have sql support linked in, rather than each plugin? -It appears that I need to call sql_drivers_init() and sql_drivers_register_all() before sql_init. Again, shouldn't the imap process do this, instead of each plugin? It should probably only be called once, so if one plugin already does it, then the second one will create problems. -When linking libsql.a in, and calling the functions mentioned above, then I get this error when starting dovecot: undefined symbol: mysql_ssl_set I'm guessing it's part of the mysql library itself, not dovecot. Can someone give me some hints on how to use dovecot's mysql library in a plugin? Thanks, Alexander

[Dovecot] Sharing Folders - or views?
by Nigel Allen 24 Apr '08

24 Apr '08

Hi All Running Dovecot v1.0.3 on FC 6. We have a Dovecot account which contains folders used by all staff. Think of the account as "Customers" and the folders as "Customer-1", "Customer-2", "Customer-3" and so on. We currently have around 650 of these customer folders. The problem is that there are currently 12 members of staff who need to see a subset of these folders (i.e. the customers that they are the manager for) but who also need to see (sometimes) the entire range of customer folders. Ideally what they would like to see is this kind of layout: +Personal Folders Inbox Trash Copies + My Customers Cust-1 Cust 7 Cust-25 Cust 33 + All Customers Cust-1 Cust-2 Cust-3 Cust-4 Cust-5 Cust-6 Cust-7 etc I suppose we could achieve this with symlinks but thought I would ask in case there is a "clever" way to achieve the same end. Thanks and Regards Nigel. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] Windows Mobile and IMAP proxy
by Onno Molenkamp 24 Apr '08

24 Apr '08

Hi, We are running Dovecot proxies in front of our Dovecot IMAP servers, and were having problems with Windows Mobile clients not being able to connect. The clients would send a LOGIN command, and immediately after the succes reply a LOGOUT command. It turns out the Windows Mobile IMAP client gets confused by the IMAP proxy first sending the command tag in the reply and then, in a seperate packet, the rest of the line. Although not being able to handle this looks like a very bad design to me (how can one ever expect to read a full line in a single read() call?) I fixed it in our Dovecot proxies because we do have clients that want to use it. Attached is my fix for the problem. Onno

[Dovecot] Adding new storage backend to Dovecot
by Earl Dreller 24 Apr '08

24 Apr '08

I'm exploring adding a new storage backend to dovecot, storing mail in some sort of database, and had a few questions. Hoping someone here might be able to help :) -Is all of the 'storage' specific code in housed in lib-storage/index? Would adding a new storage backend be as simple as recreating all of the public functions of the current /mbox or /maildir code such as they pertain to that storage mechanism? -Where is the particular storage method controlled? I've had a look around but can't seem to find where the decision to use the 'mbox' or 'maildir' code is. -Finally, if there isn't a filesystem associated with the mail storage area, obviously the index data code will need to change somewhere. Any ideas on the complexities of that? Thanks!

[Dovecot] IMAP clients generate user home folders one level higher than needed
by andel 22 Apr '08

22 Apr '08

Hi (Of course not the clinets generate the folders, dovecot does, but I wanted to have the title not be too long.) I am using static userdb: userdb static { args = uid=vmail gid=mail home=/srv/vmail/%d/%n } and I have configured the hostname in protocol lda. Now when mail arrives for a known virtual user, the home directory with all subdirectories is being created correctly unter /srv/vmail/$domain/$vuser. But when connecting from an IMAP client (I have tested Thunderbird and Outlook) a new home directory with apparently correct subfolders is bring created unter /srv/vmail/$vuser ! The connection works, I just don't see the mails which arrived since the client is mapping a directory one level higher than needed. Where do I have to look for the cause? I did not find anything reasonable yet. Thank you in advance, David

When I try to compile I keep getting this at the end: Building with SSL support ........... : no Building with IPv6 support .......... : yes Building with pop3 server ........... : yes This is what my configure line looks like: ./configure --prefix=/usr/local/dovecot --with-pop3d --with-ssl=openssl --with-ssldir=/usr/local/vps/sharedssl/openssl --with-passwd-file Am I not doing something right? Am I reading the configuration setup wrong? Any help would be great! Thanks.

[Dovecot] odd behaviour with antispam plugin
by ZyanKLee 22 Apr '08

22 Apr '08

hey, in my dspam database there has been some odd behaviour: during training dspam had created an uid entry named by the local part of the email. i.e.: user1 I use a virtual setup using dovecot, postfix and postfixadmin. On my first try I set up a database for dspam itself and there this happened. After I couldn't figure out how to solve this, I merged the database into the postfixadmin database. But using just the username for identifying email adresses is a bit critical within a virtual environment with multiple domains, isn't it? if one would not merge the databases - how could he solve this problem?

[Dovecot] Moving Maildir email messages and backing things up.
by Karl Schmidt 22 Apr '08

22 Apr '08

I just moved to dovecot with Maildir. I think this is probably a stupid question, but I couldn't find an answer after an hour of googling and searching the wiki. What would happen if I ran a script that did this: mv ~/Maildir/.folder_one/cur/* ~/Maildir/.folder_two/cur/ My hunch is it might break things. What if dovecot was stopped? ,.,.,. Where can I find a list of files in ~/Maildir/ and a note on what they are? (And similarly for a ~/Maildir/.folder) I'm wondering if everything needs to be backed up, or if I can/should skip the indexes. What happens if any of these files changes during the backup? (I'm thinking I shouldn't have to stop dovecot for a backup). ---------------------------------------------------------------- Karl Schmidt EMail Karl(a)xtronics.com Transtronics, Inc.

[Dovecot] antispam plugin ehancement
by ML 22 Apr '08

22 Apr '08

I'm not a developper so I can't do it by myself, but I wonder if it could be possible to use tagSpam and tagNospam DSPAM feature to ehance user's dspam lerning experience. I even don't know if this must be done by DSPAM itself or by dovecot, but let me explain : The feature would be done by a signature replacement into tagSpam and tagNospam text, so the user would simply have to click on the link at end of the mail to learn DSPAM : # dspam.conf tagSpam on tagNonspam on # msgtag.spam If this message was classified SPAM by mistake, please click here : http://example.com/dspam-retrain.cgi?sig= {DSPAM_SIG} # msgtag.nonspam If this message should have been classified SPAM, please click here : http://example.com/dspam-retrain.cgi?sig= {DSPAM_SIG} I think a click is easier and faster than a forward, what do you think of such an implementation ? Regards, David.

[Dovecot] Feature Request - starting dovecot, config file behavior
by Charles Marcus 21 Apr '08

21 Apr '08

Hey Timo, I was wondering how much trouble it would be to again emulate the way postfix does something - in this case, the way it reads its config file when starting up. Current behavior: Postfix: If postfix encounters the same setting defined more than once, the last one wins. Dovecot: If dovecot encounters the same setting defined more than once it gives an error (also when using the 'dovecot -n' command). I like to add all of my changes to the very bottom of the config file, but otherwise leave the config file as is... this makes it very easy when updating - I can easily keep all of the new default config file, and simply merge my customizations at the end. So - how hard would it be to make dovecot simply accept the last defined setting read, instead of refusing to start? Thanks much, and glad to have you back in action! -- Best regards, Charles

[Dovecot] mailtrain with dovecot antispam plugin
by Hugo Monteiro 21 Apr '08

21 Apr '08

Hello all, and Johannes if you're around, I was trying to set up the "new" antispam plugin with the mailtrain backend, and i was trying to use the sendmail binary that's part of a qmail system. The message wouldn't get sent and i kept getting exit error 100 from the /var/qmail/bin/sendmail binary. To try to figure out what was happening, i mean a fake sendmail program, which is nothing more than a bash script to capture the command call input. The script is rather simple, it just places the calling parameters into a txt file and the stdin into another. code is #!/bin/bash echo $* > /tmp/sendmail-parms.txt exec cat<&0 >> /tmp/sendmail-msg.txt exit 0 So i tried a retrain and went to see what those txt files had. The parms.txt file was fine apparently, with cat /tmp/sendmail-parms.txt i got -f hm(a)hmonteiro.net notspam-hm(a)hmonteiro.net Then i did the same to the message file, with cat /tmp/sendmail-msg.txt, and i got the follwing Return-Path: <hugo.monteiro(a)fct.unl.pt>Delivered-To: hm(a)hmonteiro.net Received: (qmail 21616 invoked from network); 19 Apr 2008 16:21:17 -0000 Received: (simscan 1.4.1 ppid 21609 pid 21611 t 0.1451s) (scanners: regex: 1.4.1 attach: 1.4.1 clamav: 0.92.1 /m:46/d:6803); 19 Apr 0108 16:21:17 -0000 Received: from femme-fatal.resnet.costabasto.com (HELO femme-fatal) (192.168.0.20) by hmonteiro.net with SMTP; 19 Apr 2008 16:21:17 -0000 Subject: buy some viagra HURRAY X-DSPAM-Result: Innocent X-DSPAM-Processed: Sat Apr 19 17:21:17 2008 X-DSPAM-Confidence: 0.4945 X-DSPAM-Probability: 0.0330 X-DSPAM-Signature: 480a1bfd216125429498786 viagra sale really HURRAY cheap! only $5!

[Dovecot] Run command when moving messages
by Juan Asensio Sánchez 21 Apr '08

21 Apr '08

Hi Is it possible to run a command when a message is moved from a folder to another? I want this to simulate the antispam plugin, so one script would be ran when a message is moved to/from the spam folder, so the sa-learn command would be called. Thanks

[Dovecot] building a simple antispam plugin
by Alexander Prinsier 21 Apr '08

21 Apr '08

Hello, I'm trying to build another antispam plugin, but some things are a bit unclear. In backend_handle_mail I put store the signature returned from signature_extract into my antispam_transaction_context. In backend_commit it appears that the signature is empty. (It wasn't in backend_handle_mail). Somehow between backend_handle_mail en backend_commit it has been cleared... When I use i_strdup it appears to work. Anyone can tell me where this clearing happens? Is i_strdup the right way to do it then? Thanks, Alexander

[Dovecot] How to deal with mail to unknown virtual recipients?
by Andreas Ntaflos 19 Apr '08

19 Apr '08

Hello list, I am not quite sure whether this is a questions for Dovecot or Postfix. I have set up, virtual hosting for one domain (for test purposes) using a passwd-file as passdb and a static userdb (see dovecot -n at the end) along with Postfix in a manner described in [1], i.e. a non-Postfix mail store. Other than that I also do hosting for the canonical domain which is for users with a regular Unix account on the system (looked up via PAM) The virtual domain shall be "example.org", with two users "alice(a)example.org" and "bob(a)example.org". But today I received spam mail (which was correctly identified as such by amavisd-new) for "info(a)example.org" and "sales(a)example.org", two recipient addresses that do not exist. According to [1] "it's left up to the non-Postfix delivery agent to reject non-existent recipients from local submission or from local alias expansion." How to deal with such a situation? The sender address was clearly forged so returning a failed delivery message is pointless. The messages are now hanging around in the queue with a status of "deferred: temporary failure". The logs show: dovecot: auth(default): passwd(info(a)exmaple.org): unknown user dovecot: auth(default): passwd-file(info(a)mexample.org): unknown user dovecot: auth(default): static(info(a)example.org): passdb doesn't support lookups, can't verify user's existence postfix/pipe[25328]: C7EA18BC0B5: to=<info(a)exmaple.org>, relay=dovecot, delay=1.4, delays=0.07/0.02/0/1.3, dsn=4.3.0, status=deferred (temporary failure) The dovecot relay is defined in /etc/postfix/master.cf: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} The question, once again, is: what to do in such a situation? A catch-all address could be set up, but to what end? It would just catch a lot of spam over time. What is the correct way to deal with this? More importantly: is there even anything Dovecot could (or should) do?

[Dovecot] Delete antispam emails
by David Reid 19 Apr '08

19 Apr '08

I'm using dovecot with the antispam plugin to allow for training, but how do I delete emails once they've been trained? If I delete them from the folder using an email client they get retrained as valid emails when they're moved to the trash folder! D'oh. I'm looking, ideally, for a solution that doesn't need a script to be run per user as I have a number of users using this feature. Also, the cleanspam script doesn't seem to be able to find the folder I'm using ('SpamTrain') so what format should I use? Thanks. david

[Dovecot] CRAM-MD5 HMAC-MD5 password algorithm for PHP
by Hajo Noerenberg 18 Apr '08

Hi, based on the recent discussion by Bill Cole and Douglas Willcocks I've quickly put together a PHP script which generates MD5 'contexts' for Dovecot's password files: http://www.noerenberg.de/hajo/pub/dovecot_hmacmd5.php.txt The script has not been tested extensively, so use it on your own risk :) Most of the code has been shamelessly stolen from various sources. You'll find the names in the header of the script. Hajo

[Dovecot] Message UID Question
by Joe Allesi -X (joallesi - Coyote Creek Consulting at Cisco) 18 Apr '08

18 Apr '08

I have referred to the wiki and the RFC, but I still can't find the exact answer I'm looking for. From what I know, Dovecot uses the IMAP standard of 32 bit integers to uniquely identify messages. After a message is deleted from the mbox, can this UID ever be reissued to a new message or is that UID retired? What about after the 2 billion limit is reached? Thanks!

[Dovecot] Please help: LDAP configuration _almost_ works.
by Jack McKinney 18 Apr '08

18 Apr '08

Red Hat Linux release 7.2 (Enigma) OpenLDAP 2.3.38 Dovecot 1.0.12 SHORT VERSION ----- ------- Here is my dovecot-ldap.conf: hosts = ldap.lrtz dn = cn=varmail,ou=users,dc=lorentz,dc=com dnpass = ********* ldap_version = 3 auth_bind = yes pass_filter = (&(objectClass=inetOrgPerson)(mail=%Lu)) base = ou=users, dc=%Dd scope = onelevel I have tested using the above information with ldapsearch, and it works fine. However, when dovecot tries to authenticate the user, the LDAP server receives the query and responds to it (according to the LDAP log file), but dovecot just hangs there. 180 seconds later, it drops the IMAP client. E.g.: The dovecot log shows: Apr 3 08:13:21 fourier dovecot: auth(default): new auth connection: pid=15774 Apr 3 08:13:30 fourier dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=IMAP^Isecured^Ilip=x.x.x.x^Irip=y.y.y.y^Iresp=<hidden> Apr 3 08:13:30 fourier dovecot: auth(default): ldap(jackmc(a)lorentz.com,y.y.y.y): bind search: base=ou=users, dc=lorentz,dc=com filter=(&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com)) Apr 3 08:16:30 fourier dovecot: imap-login: Disconnected: Inactivity: method=PLAIN, rip=y.y.y.y, lip=x.x.x.x, TLS The OpenLDAP log shows that the query is received and that it returns a match: Apr 3 08:13:30 fourier slapd[14039]: conn=7 op=3 SRCH base="ou=users,dc=lorentz,dc=com" scope=1 deref=0 filter="(&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com))" Apr 3 08:13:30 fourier slapd[14039]: conn=7 op=3 SRCH attr=uid Apr 3 08:13:30 fourier slapd[14039]: conn=7 op=3 SEARCH RESULT tag=101 err=0 nentries=1 text= LONG VERSION ---- ------- My users login using their email address as username. Each domain has their own LDAP subtree. Each user has an entry in the ou=users subtree of the domain subtree, and has a mail: field (inetOrgPerson) listing their email address/login name. I am trying to use auth_bind: when I login with jackmc(a)lorentz.com, dovecot should search for mail=jackmc(a)lorentz.com in the onelevel below ou=users,dc=lorentz,dc=com and find me as "cn=Jack McKinney,ou=users,dc=lorentz,dc=com". I have created an entry in LDAP (varmail) that should be able to do this query. Indeed, from the command line, it works: ldapsearch -h ldap.lrtz -b 'ou=users, dc=lorentz, dc=com' -D 'cn=varmail,ou=users,dc=lorentz,dc=com' -x -W -s onelevel '(&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com))' Enter LDAP Password: # extended LDIF # # LDAPv3 # base <ou=users, dc=lorentz, dc=com> with scope oneLevel # filter: (&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com)) # requesting: ALL # # Jack McKinney, users, lorentz.com dn: cn=Jack McKinney,ou=users,dc=lorentz,dc=com objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson cn: Jack McKinney givenName: Jack McKinney sn: McKinney mail: jackmc(a)lorentz.com # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 It appears that dovecot performs the above query successfully, but then never uses the password and retrieved DN to attempt to bind and authenticate the user. Instead, it just times out. (See log files above in the SHORT VERSION). I tried to add pass_attrs, in case there was a bug in dovecot where it ignores the reply if there are no pass_attrs (even though none are needed), but it still fails the same way. Timo Sirainen suggested that I add a debug line to src/auth/db-ldap.c ldap_input() around line 372: msgid = ldap_msgid(res); // added line: i_info("LDAP: Received reply %d", msgid); I did this. Now, when the server first starts up, this line is logged. However, it is not logged when it queries the LDAP server as a result of an IMAP connection needing authentication. -- Jack McKinney GPG 1024D/99C6A174 jackmc(a)lorentz.com YM:lfaatsnat2006 AIM:jackmclorentz "There is no parameter that makes it impossible for you to perform still more excellently." -Mario Cuomo, on the lack of a clock in baseball
