[Dovecot] HP-UX troubles
by Matthias Luehr 09 Aug '07

09 Aug '07

Hi there, I got dovecot compiled and running on HP-UX 11.23. It's using LDAPUX and PAM for authentication. So far, it works. But after logging in the connection is closed immediately. It looks like this: telnet <ip> 143 Connected to ... Escape character is '^]'. * OK Dovecot ready. a01 login <user> <pass> Connection closed by foreign host. The dovecot log says: Error: imap-login: fd_send(7) failed: Bad file number Error: child 22629 (login) returned error 89 As far as I can see, the problem seems to reside in dovecot's fdpass.c... dovecot version: 1.0.3 gcc version: 2.9 Any ideas or solutions? Thanks in advance, Matthias

[Dovecot] UIDL match from 0.99.13 to 1.0-1.2
by Daniel Davidson 09 Aug '07

09 Aug '07

I am moving from and old FC2 system to a new RHEL5 system and am having trouble getting the UIDLs to move over right, mainly the UID. I copy over the mailbox, and see the x-uid in the message is what it was on the old server, but when I telnet in to check pop, it rewrites x-uid in the message to something new, causing old messages to get downloaded again, which is not what we want I have tried setting pop3_reuse_xuidl to yes, but that did not change anything, probably because that is the wrong header (I do not have x-uidl, but I do have x-uid). I do have pop3_uidl_format set to %v.%u for compatibility. On the old system the first five are: +OK Logged in. uidl +OK 1 1095087961.3092736 2 1095087961.3092737 3 1095087961.3092738 4 1095087961.3092739 5 1095087961.3092740 On the new system the first five are: +OK Logged in. uidl +OK 1 1095087961.3093018 2 1095087961.3093155 3 1095087961.3093156 4 1095087961.3093157 5 1095087961.3093158 Any help would be appreciated, I do not understand how it is generating the UID portion.

[Dovecot] Userdb and home directories
by Mike Brudenell 09 Aug '07

09 Aug '07

Greetings - I've just discovered an oddity I didn't know I had... We have two NetApp filers: one serves people's home directories; the other their message store and control files filestores. At the moment the first of the two filers is not accessible to my Dovecot system and I assumed all would be well because, as far as I knew, I wasn't using it at all. However in practice Dovecot DOES appear to be using it: it is trying to chdir() to my home directory when I login, finds it can't at the moment (because of a problem giving "Permission denied"), and closes the connection. I've read the pages on home directories and the userdb on the Wiki and it advises that having a home directory is beneficial. I'm happy to create a subdirectory for this within a user's control files directory, but do NOT want it on our normal filestore: we can't have mail inaccessible because a user's home directory is inaccessible because the other filer is out of action. We use shadow for the passdb and passwd for the userdb (see dovecot - n output below). I'm trying to work out how to override the home directory returned from NIS. Ultimately I'd like to use this template: /mailstore/control/%1Ln/%Ln/home but for the time being while I'm trying to work out how to do it have my own area hard-coded in (as it's only me logging in to the test system): /mailstore/control/p/pmb1/home I'm specifying this with the "args" directive in the userdb section as follows: args = home=/mailstore/control/p/pmb1/home but it isn't being picked up. What am I doing wrong, please? (We want to continue using uids and gids etc from NIS so I don't think using the static userdb is the right thing to do?)

[Dovecot] dovecot-sieve vacation changes
by pod 09 Aug '07

09 Aug '07

I'd like to put forward the following patch for dovecot-sieve. Essentially this just merges in some changes made in CMU sieve 2.3.8 and as such brings the behaviour more in line with RFC 3834 "Recommendations for Automatic Responses to Electronic Mail": - fixes erroneous sender "-request" substring match - checks for existence of a selection of list-* headers - expands "named-as-recipient" header checks to "Resent-To", "Resent-CC" and "Resent-BCC" fields. Note that the appended patch also includes a fix for some missing parentheses in the "resent-to" test which resulted in some extra work being done but was otherwise harmless. The fix has been sent to <cyrus-bugs+(a)andrew.cmu.edu> - prefixes subject in response with "Auto: " rather than (non-expanding) "Re: " I also, mostly for kicks, attach two sieve-like scripts that attempt to encapsulate the when-not-to-respond logic as implemented (if the patch were to be applied) and as advised by RFC 3834 respectively. I wrote these as an exercise to help me gain a better understanding of sieve and the CMU implementation. I'm not sure they are otherwise useful.

[Dovecot] NFS rquota support
by Timo Sirainen 09 Aug '07

09 Aug '07

For v1.1, probably applies to v1.0 code pretty easily too: http://hg.dovecot.org/dovecot/rev/078d9dde99c8 The other rquota patches had authunix_create_default() call. Is this needed/useful? The client is now always created+destroyed for each quota lookup. I'd think it would be faster if it was created only once, but does it then break something? If the above isn't done, clnt_create() could be replaced with clntudp_create() and have the struct sockaddr_in cached. Patches welcome. :)

[Dovecot] Shared folder hierarchies, multiple groups
by Benjamin R. Haskell 09 Aug '07

09 Aug '07

Hi, I'm trying to set up two shared folder hierarchies on my Dovecot installation for two groups of employees, all of whom should only have access to their own hierarchy. Any employee should be able to create sub-folders and generally have full access to the hierarchy. My initial setup was to create two public namespaces, Shared-One and Shared-Two. Each is a Maildir under /var/mail. The actual shared folders seem to be working fine in terms of adding and accessing folders and messages, and there are no problems at all for the 'admin' user, who belongs to both the shared1 and shared2 Unix groups. The problem is for other users, where trying to (IMAP-) LIST folders fails. (sanitized) IMAP session log: ('user2' is in group shared2) * OK Dovecot ready. A LOGIN user2 pass A OK Logged in. B LIST "" "%" * LIST (\Noselect \HasChildren) "/" "Shared-One" B NO Internal error occurred. Refer to server log for more information. [2007-08-02 09:01:23] In the mail logs I find: dovecot: IMAP(user2): stat(/var/mail/Shared-One/cur) failed: Permission denied Relevant permissions: 2770/drwxrws--- shared1 shared1 /var/mail/Shared-One 2770/drwxrws--- shared1 shared1 /var/mail/Shared-One/cur 0660/-rw-rw---- shared1 shared1 /var/mail/Shared-One/dovecot-shared And similarly for Shared-Two. (replace shared1 with shared2 everywhere) Among other things, I've read: http://wiki.dovecot.org/SharedMailboxes http://wiki.dovecot.org/ACL http://wiki.dovecot.org/MainConfig http://wiki.dovecot.org/Namespaces I don't want to use vfile ACL's (I think) because I want users to be able to create subfolders at will, and I don't want to have to add a dovecot-acl file per-folder. (Is there a way to set global defaults on a global basis? [not per-folder]) I also think there would be a problem with the hierarchies being similar. (e.g. both have a 'Projects' sub-folder, but there's a pretty clear WARNING on the wiki about mailbox name conflicts.) I can't use symlinked Maildirs, because new subfolders get created under ~user/Maildir/. (Want them under /var/mail/Shared-X/) I can't use hidden namespaces, because employees use Outlook (uggh), and I couldn't figure out how to "find" the namespace when it was hidden. (That seemed like the closest thing to a solution - it solved the LIST problem.) Ideally, Shared-Two wouldn't even be visible to members of Shared-One, and vice versa. But, that's at least an acceptable "problem" I could live with. Any suggestions? Thanks, Ben

[Dovecot] Bug in Exim->Dovecot auth
by Chris Laif 09 Aug '07

09 Aug '07

Hi. I'm using SMTP auth with Exim authenticating against Dovecot's auth socket. My (excellent) SMTP test tool "swaks" (http://jetmore.org/john/code/#swaks) tries multiple auth mechanismus consecutively which leads to the following message in Dovecot's log file: Error: auth(default): BUG: Authentication client gave a PID 6738 of existing connection I'm not sure where to report this bug, exim's or dovecot's mailing list, so I'll try here first :) Chris <- 250-AUTH PLAIN LOGIN <- 250 HELP -> AUTH PLAIN AHh5egBra2s= <** 535 Incorrect authentication data -> AUTH LOGIN <** 435 Unable to authenticate at present *** No authentication type succeeded -> QUIT

[Dovecot] Authentication problem - or is it?
by Anne Wilson 09 Aug '07

09 Aug '07

My old server ran v.0.99, and this is the first time I've tried to get v.1 running. When I try to test it with telnet I see telnet localhost 143 Trying 127.0.0.1... Connected to david.lydgate.lan (127.0.0.1). Escape character is '^]'. * OK Dovecot ready. x login anne xxxxxx x OK Logged in. Connection closed by foreign host. I assumed it was an authentication problem (I want to use /etc/passwd as the authentication file) but it does say that I managed to log in. If so, what could be causing it to close immediately? Anne

[Dovecot] v1.1.alpha2 released
by Timo Sirainen 09 Aug '07

09 Aug '07

http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha2.tar.gz http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha2.tar.gz.sig Hopefully the next release can be v1.1.beta1. I'm not aware of any major problems and I think I'm pretty much done with new features (except for dbox). The largest changes since alpha1: * Removed THREAD indexing. It's a bit buggy and I think there's a better chance of releasing a bugfree v1.1 soon if it's not included. I'll fix it after v1.1. * Removed THREAD=X-REFERENCES2 also because it wasn't as easy to implement with the old threading code. I might put this back though if there's enough interest. * PAM always works in blocking=yes mode now. If you have problems with memory leaks, change auth_worker_max_request_count setting. + Filesystem quota backend supports inode limits, group quota and RPC quota for NFS. + SEARCH and SORT finally compare all characters case-insensitively. We use i;unicode-casemap algorithm. + Config files support splitting values to multiple lines with \ + Winbind NTLM and GSS-SPNEGO mechanism patches by Dmitry Butskoy.

[Dovecot] Not seeing other folders with some clients

Hi, With dovecot 1.0.2, depending on the client I can only see inbox, or all the folders. I see all the folders with pine and balsa, but can see only the inbox with squirel mail and thunderbird. Any idea what's going on here ? Thanks. Yves. ---- Yves Dorfsman yves(a)zioup.com http://www.SollerS.ca

[Dovecot] BUG (and suggested fix) in maildir code
by Tom Vajzovic 08 Aug '07

08 Aug '07

Hi all I'm using dovecot 1.0.rc15 to serve a maildir by IMAP. I have an IMAP subdirectory called subscriptions. The messages are in maidir/.subscriptions/cur/ etc. Dovecot is renaming the directory .subscriptions/ to subscriptions/ This means that when my IMAP client requests this directory, it gets the message "no such directory", and dovecot also gives the error message: dovecot: IMAP(tcv): read() failed with subscription file /var/mail/maildir/tcv/subscriptions: Is a directory The two should be able to live happily side by side, with the subscriptions file called "subscriptions" and the maildir called ".subsciptions". The offending function is maildir_subscriptions_convert_099() in src/lib-storage/index/maildir/maildir-storage.c Can someone with developer access please change this so that rename() is not called if subscriptions is a directory. Thanks, Tom

[Dovecot] dovecot.conf an <TAB> chars
by Sascha Holzleiter 08 Aug '07

08 Aug '07

Hi, I just wanted to "beautify" my dovecot configuration file and as one of the first comments suggests whitespaces and <TAB> should be completly ignored but that doesn't seem to be the case, e.g.: postmaster_address<TAB>= some(a)address.de results in an configuration error as the postmaster_address is not set. Using just a space or replacing the <TAB> char with space chars resolves the problem. This is with dovecot version 1.0.3 on Debian and FreeBSD. Greetings, Sascha

[Dovecot] OpenBSD and too many open files
by Bryan Vyhmeister 07 Aug '07

07 Aug '07

I posted some questions a few months back and received lots of great help in getting my dovecot/postfix/LDAP setup working. Initially, I ran into the pipe failed too many open files error. I am running this setup on OpenBSD/sparc64 4.1-stable and so I put dovecot in its own class and upped the maxfiles setting for that class. This was back with dovecot 1.0 and everything worked fine. I just recently upgraded to dovecot 1.0.2 from ports and now I am having the same problems again. I moved kern.maxfiles for that class from 2048 up to 3404 and yet I still run into the error. When I do, I have to restart dovecot to get things running again. Output of: su -c dovecot root -c 'ulimit -a' time(cpu-seconds) unlimited file(blocks) unlimited coredump(blocks) unlimited data(kbytes) 1048576 stack(kbytes) 8192 lockedmem(kbytes) 634482 memory(kbytes) 1898080 nofiles(descriptors) 3404 processes 1044 sysctl kern.maxfiles gives: kern.maxfiles=3404 My main IMAP accounts reside on this server and I have somewhere in the 25000 range of stored messages. Could this be causing the issue? I only have maybe a dozen other users using this server right now but I am planning on putting 500 users on it soon. I added another heavy IMAP user shortly before these problems started but I don't know if that has anything to do with it or not. Likewise, I am not sure if the dovecot 1.0.2 upgrade had any effect either although it did coincide. Any ideas? Thank you. Bryan

[Dovecot] vfile ACL's
by Benjamin R. Haskell 07 Aug '07

07 Aug '07

(Sorry for the impatience. This was one of several questions in my email from yesterday. I thought I might have better luck being more direct.) Is there a way to set ACL's, using the vfile backend, on a truly global basis? or hierarchically (i.e. .Maildir.Sub inherits from .Maildir)? The wiki page says: "The default ACLs for mailboxes is to give owner all permissions and other users none. Mailboxes in public namespaces don't have owners, so by default no-one can access them." Is this configurable? Thanks, Ben

[Dovecot] dovecot + LDAP-SASL ?
by Hadmut Danisch 07 Aug '07

07 Aug '07

Hi, just a question: I know that dovecot supports SASL authentication and supports LDAP. Which means that dovecot performs the SASL methods itself and stores the plaintext secret on LDAP. But it is also possible to have the LDAP do the SASL work and dovecot just pass SASL messages through? Even when the LDAP server uses a proprietary SASL method not supported by dovecot? regards Hadmut

[Dovecot] Ideas for Webmail/OTP
by Frank Behrens 07 Aug '07

07 Aug '07

I want to discuss some problems/enhancements for dovecot in a webmail/otp setup. For access to an IMAP server like dovecot I see different client types: a) a "normal" MUA installed in a more or less trusted environment b) remote access via "webmail" from untrusted environments For a) I see with dovecot and other IMAP servers no problems, tricky is the setup for b). If you use a webmail client in an untrusted environment the risk is high, that keyloggers and other malware steal your password. One easy solution is to use One-Time-Passwords (OTP). The otp setup for interactive logins (e.g. ssh) is easy, but until now I did not find any easy to use solution for webmail. The main problems I see - In most cases a webmail client does not hold a persistent connection to the IMAP server, but makes a login for every request. - The webmail clients are not prepared to display the otp password challenge to the user. When we say "otp" with IMAP we further have to distinguish a) the OTP SASL authentication mechanism b) OTP configured by PAM. I believe a) is implemented in new dovecot 1.1 version, but I prefer b), because - it works with many clients without special client support - all authentication setup is central in the os. All above described problems are not specially linked to dovecot, but I believe with dovecot there is an easy solution to solve them. :-) Solution 1: When PAM is configured for IMAP the user can use a one-time-password in the same way as before. The problem is, that the user must know the sequence number for the password (otp challenge), so we need a way to display it. The PAM module supplies the otp challenge in the conversation function, but the challenge is not processed by the IMAP server. My proposal: The IMAP server stores the challenge from the conversation function and includes it in the LOGIN response, when the login was not successful. So a user can try a login with a wrong dummy password and get knowlegdge about the current otp sequence. The webmail server should be extended in a way, that it displays the complete IMAP error message, when a login fails. Solution 2: Webmail clients do not use persistent connections in most cases. A OTP login needs different passwords for every displayed web page. My proposal: Use dovecot's login cache and do not ask the os for every login. :-) Solution 3: When we configure PAM we can restrict/allow it's use depending on IP address of client. Unfortunately with a webmail client the IMAP client is always the the webserver. It should be possible, that the webserver forwards the client IP address to the IMAP server. Furthermore to use dovecot's login cache as described above in a safe manner, the IP address should be compared, too. My proposal: Create a new IMAP command "XSETREMOTEIP". With this IMAP extension a client can set the real IP address of remote client. The access to this command is restricted to the webserver with a new configuration parameter "trusted clients", which holds an IP address with mask. I ask to discuss these solutions. It seems to work, I'm making the first tests now. I have patches for dovecot and squirrelmail, but they are very "quick and dirty". They show a possible solution, but not a clean implementation. Do you believe, that we can build a good webmail system this way, or do you have better solutions?

[Dovecot] A few dovecot 1.1 bugs - sort, flag reset and etc.

[Dovecot] [PATCH] Split sql drivers from lib-sql to plugins
by Tomas Janousek 07 Aug '07

07 Aug '07

Hi, in order to solve rhbz#170960 [1], I split the sql drivers to plugins so that they are loaded dynamically and can be split to separate packages. [1] https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=170960 The patches are here: [2] http://people.redhat.com/tjanouse/dovecot/145241/dovecot-1.0-split.patch [3] http://people.redhat.com/tjanouse/dovecot/145241/dovecot-trunk-split.patch (mv src/lib-sql/driver-mysql.c src/plugins/sql-mysql/, etc., afterwards) I'd like to ask for your comments and whether it's ok for inclusion or at least ok to use in the Fedora package. Regards, -- Tomas Janousek, SW Engineer, Red Hat, Inc.

[Dovecot] cache questions
by Daniel Watts 06 Aug '07

06 Aug '07

Hi Guys, We have: auth_cache_size = 2048 #Kb auth_cache_ttl = 900 #life of the cache Seems to work well (though haven't tried looking at stats). Only problem is that every so often, one of our new users tries to log in quickly before the account is marked (in a db) as 'active'. They use the right password but the sql query fails because the active flag is not yet set. This results in their trying to log in and failing for 15 minutes (900 seconds) until the cache clears. Is this dovecot caching negative results? Is this a good idea and can it be disabled? Some more questions: 1. Is the expire time on a per-login basis or for the entire cache? If someone logs in 14 minutes after the last expiry is their data cached for just 1 minute? 2. If it is per-login, is the time reset after every hit? If someone is using webmail and hitting the cache every 5 minutes, will the cache keep the information? 3. How does the cache size relate to number of distinct logins? Roughly how many auth datasets cached per 1MB of cache? Thanks! Daniel tg3 dovecot # dovecot --version 1.0.rc27 p.s. please CC my email so I know when this has been replied to. I will respond to group!

[Dovecot] Benchmark: Appending 250k messages
by Timo Sirainen 06 Aug '07

06 Aug '07

I just changed Dovecot v1.1 code to work much more nicely when appending new messages to large mailboxes. Dovecot hg (cydir format, fsync_disable=yes): ./imaptest secs=1 ./imaptest - append=100,0 logout=0 msgs=10000000 clients=1 seed=1 secs=300 Logi Sele Appe 100% 100% 100% 1 1 2322 1/ 1 0 0 1998 1/ 1 0 0 2293 1/ 1 0 0 2009 1/ 1 0 0 1789 1/ 1 0 0 1245 1/ 1 0 0 43 1/ 1 0 0 32 1/ 1 0 0 881 1/ 1 0 0 2137 1/ 1 .. 0 0 704 1/ 1 0 0 771 1/ 1 0 0 388 1/ 1 0 0 831 1/ 1 0 0 572 1/ 1 0 0 766 1/ 1 Totals: 1 1 251397 Averaging 837/sec. The append speed jumps around quite a lot. Typically it's around 800-1000/sec, but it jumps between 0-500/sec also quite often. I'm not sure why that is. Cyrus v2.3.8 (fsync and fdatasync calls disabled from code): ./imaptest - append=100,0 logout=0 msgs=10000000 clients=1 seed=1 secs=300 Logi Sele Appe 100% 100% 100% 1 1 2587 1/ 1 0 0 1907 1/ 1 0 0 1597 1/ 1 0 0 1260 1/ 1 0 0 1220 1/ 1 0 0 1151 1/ 1 0 0 1068 1/ 1 .. 0 0 121 1/ 1 0 0 127 1/ 1 0 0 128 1/ 1 0 0 126 1/ 1 Totals: 1 1 79613 Averaging 265/sec. The speed slows down pretty consistently, there's no jumping like with Dovecot.

[Dovecot] Disable IMAP for certain users, but not Webmailer
by FORMER 03 | Baltasar Cevc 06 Aug '07

06 Aug '07

Hi everybody, I'm planning to set up our new mail system using the Dovecot mailbox server. It mostly works fine yet (it's quite straigt forward to set up, I'd say), but there's a thing I haven't been able to find out yet. We provide POP3 access for all users, but want to restrict IMAP access to some of them (because IMAP users tend to leave more messages on the server, thus increasing storage needs). I used to do it by providing two services. One provided the public imap and checked a database flag during authentication, the other just provided IMAP on localhost and did not check the "allowed to use IMAP" flag. What I've found for Dovecot is http://wiki.dovecot.org/Authentication/RestrictAccess While this allows me to provide full POP3 to everybody and in the same time restricting IMAP, I don't see a possibility Is there any possibility to achieve what I need without having two completely separated instances of Dovecot running? I'd appreciate any hints, pointers to documents etc. Thanx, Baltasar -- _____ FORMER 03 GmbH _____ infanteriestra§e 19 haus 6 eg _____ 80797 muenchen _____ baltasar.cevc(a)former03.de _____ www.former03.de _____ fon 089.322112.29 _____ fax 089.322112.11 _____ mobil 0178.691.2233 _____ geschftsfhrer _____ sebastian fiedler _____ gert zellentin _____ handelsregister _____ HRB Mnchen 148468 _____ steuer _____ ust.-id DE 2291076876

[Dovecot] dovecot.index.cache weirdness
by Tan Shao Yi 06 Aug '07

06 Aug '07

Hi Timo, Just a quick check, may I know if the following output of idxview is normal? (see bottom of e-mail) I am running dovecot-1.0.3 on a Solaris 10 SPARC box. Deleting dovecot.index.cache does not seem to help for this user; it keeps getting regenerated with these same lines. I seems that I have to set mmap_disable=yes on this box to have a "clean-looking" dovecot.index.cache. Is it mmap related? Or it just happens to be a coincidence?

[Dovecot] Some of my IMAP Folders vanished in some MUAs
by Dominik Schulz 05 Aug '07

05 Aug '07

Hi, I'm using dovecot for some time now. Previously I was using Courier and I've migrated this setup to dovecot which went pretty fine. Now I'm experiencing some strange behaviour when using some newer mail clients. Some of my Folders, like "spam", are vanished. The strange point is that it only happens in some clients, like Thunderbird 2.x+ or KMail 3.5.x. In others, like Thunderbird < 2, Mutt or my Webmailer (Horde) they still show up. These folders are still there, i.e. in the filesystem, and the permissions seem to match those of the other folders which can be seem in all MUAs. I don't know if this is even related to dovecot but I think this is where I should start looking for an solution. I'm using dovecot 1.0.rc15 from Debian (stable/etch). It'd be great if anyone was able to help me. Thanks in advance. Best Regrads Dominik Schulz

[Dovecot] Password Encryption
by Dave Morrow 05 Aug '07

05 Aug '07

Hi all. I hope this is not a RTFM-type question, but I've been unable to find a searchable archive of this mailing list....... I recently began investigating using Dovecot/Postfix/MySQL solution. I've been following the documentation http://wiki.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL?highlight=%28m ysql%29 While everything seems to have gone right, I have been unable to successfully login to the IMAP server using Outlook Express. It seems that the problem may relate to PostfixAdmin storing passwords in the mysql database md5 encrypted, and Dovecot is not able to read them, but I am not certain. The error when a client logs in is something like dovecot: auth-worker(default): plain_md5_verify(testuser1(a)mydomain.com): Invalid password encoding David Morrow Technical Systems Lead Autodata Solutions Company David.Morrow(a)Autodata.net <mailto:David.Morrow@Autodata.net> http://www.autodatasolutions.com <http://www.autodatasolutions.com/> Tel: (519) 963-3020 Fax: (519) 451-6615 Think slowly.

Yep... and we have 500K very active users on it. We've scaled Dovecot horizontally without NFS, just lots of independent Dovecot server intances with smart proxy/mail-routing infrastructure around it. It can easily scale to millions of users this way. Just make sure you throw enough disks at it and you'll be fine, with or without NFS. > Do you think it's a good solution to use one synchronised local Openldap on each > server Dovecot ? No. I'd replicate your ldap database on a few servers that are dedicated to that purpose, and on each mail server use Dovecot's auth_cach feature to minimize how often it needs to query ldap. > Do you think It's possible to use Postgresql or MySQL instead of Openldap ? We use MySQL. MySQL handles frequent writes better than OpenLDAP from our experience. It is also simpler for us to do replication and troubleshooting because we employ several MysQL gurus already. > Are cyrus or courrier-imap better solutions ? Definitely not courier-imap, because of it's lack of indexes.

My opinion is Zimbra is too heavy beccause of the way mail is stored on the backend. Dovecot with maildir scales out well, and the promise of dbox mail storage format appears that it will make it even more scalable down the road. Bill

[Dovecot] MD5 mis-match
by Big Pizzle 03 Aug '07

03 Aug '07

Hi all, I'm almost finished building our new load balanced email server that are attached to an NFS mountpoint. There are currently two e-mail servers connected to the NFS share. Both email servers are running CentOS 4.5 with Postfix 2.4.3, Dovecot 0.99, and authenticating via LDAP. Dovecot is using Maildir format. I've been trying to do some benchmarks using Postal and Rabid, and whenever I run rabid, I'm getting errors like this: MD5 mis-match, calculated:a628289996ce19910ebbd4eef2ebc3fc, expected 9406a7cf56afb5a1308eb5377e141719! However, when I tail the /var/log/maillog, I don't see errors - I just see the pop3-login. Just wondering if that is okay. I've also been trying to find an RPM for Dovecot 1.0.3, with no avail. Anyone know where I can get one? Thanks in advance. Patrick

[Dovecot] Looking for RPM for 1.0.3 for CentOS with imap, ldap, and ssl
by Big Pizzle 03 Aug '07

03 Aug '07

Hi, I don't know how to compile Dovecot from src rpm;s - in fact I tried and failed miserably. The only other src rpm I have ever built was postfix, and I ran into a whole bunch of errors trying to build an rpm from the src rpm at ATRpm. Anywho, I was wondering if one of you wonderful Dovecot members would be willing to create an RPM for CentOS 4.5 that includes ldap and ssl. Or, if someone knows of a URL I can go to and follow a Dovecot-related src rpm build tutorial, that would be of great help too. Heck - I'll even settle for a 1.0.2. Since Dovecot doesn't support 0.99 I want to make sure I have the most recent package. Thanks in advance. Patrick

[Dovecot] Dovecot strong or not for a big Webmail architecture
by John fistack 03 Aug '07

03 Aug '07

Hello, Do you think Dovecot could handle millions of active users in a big architecture ? This cluster could be for example (each server is a bi quad Xeon 2.66 Ghz) : - 40 Dovecot servers - 4 LVS - 20 Apache+PHP - 2 Openldap - 20 Postfix + ClamAV + SpamAssassin - 1 NFS Netapps For millions of user it could be multiple different clusters of 40 Dovecot servers with 1 Netapp for each cluster. I want to work in NFS. I've experimented problem with Cyrus and NFS on Netapp. I want to use maildir, I can manage limitations of inodes with Netapp. I know webmail.us use Dovecot, what is the most big dovecot architecture known ? Do you think Dovecot can handle 1 million of active users in a good architecture ? Do you think it's a good solution to use one synchronised local Openldap on each server Dovecot ? Do you think It's possible to use Postgresql or MySQL instead of Openldap ? Are cyrus or courrier-imap better solutions ? Someone say "Zimbra is highly scalable and fast", I think Zimbra could be to heavy in this architecture, is Dovecot scalable ? Thank you for your ideas. Regards.

[Dovecot] dovecot 1.0.2, sieve 1.0.2 and regex
by Alexander Hoogerhuis 03 Aug '07

03 Aug '07

I've just ported a largeish procmail script across to sieve and want to get to use wildcards in filing mail and can't seem to get regex to work. The script starts nicely with: > require ["fileinto","regex","envelope","vacation","regex"]; and a bit down these few lines comes into play: > elsif header :regex "From" "logwatch.*stuff.com" { > fileinto "INBOX.Admin/Logwatch Stuff"; > } and regex just never seem to catch. I have 50ish machines in the stuff.com domain, and writing an induvidual section like this works: > elsif header :contains "From" "logwatch(a)a.stuff.com" { > fileinto "INBOX.Adin/Logwatch Stuff"; > } > elsif header :contains "From" "logwatch(a)b.stuff.com" { > fileinto "INBOX.Adin/Logwatch Stuff"; > } etc. But this shouldn't be neccesary? mvh, A

I am trying to authenticate using "PLAIN" but I don´t know how. that´s what I am doing: telnet conny.MYDOMAIN.de 143 Trying IP.AD.RE.SS... Connected to conny.MYDOMAIN.de. Escape character is '^]'. * OK dovecot ready. a1 authenticate plain + a1 NO Authentication failed. what do I have to send after receiving the "+"-symbol? dovecot is waiting for something base64-encoded and I tried to give him by typing my username and pass and encrypted it here : http://www.php-einfach.de/base64_generator.php But I don´t know the correct syntax and it drives me crazy.... thanks for ANY help Steve .

[Dovecot] v1.0.3 released

02 Aug '07

http://dovecot.org/releases/1.0/dovecot-1.0.3.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.3.tar.gz.sig - deliver: v1.0.2's bounce fix caused message to be always saved to INBOX even if Sieve script had discard, reject or redirect commands. - LDAP: auth_bind=yes and empty auth_bind_userdn leaked memory - ACL plugin: If user was given i (insert) right for a mailbox, but not all s/t/w (seen, deleted, other flags) rights, COPY and APPEND commands weren't supposed to allow saving those flags. This is technically a security fix, but it's unlikely this caused problems for anyone. - ACL plugin: i (insert) right didn't work unless user was also given l (lookup) right. - Solaris: Fixed filesystem quota for autofs mounts.

[Dovecot] mbox inbox default
by bhayden＠umn.edu 01 Aug '07

01 Aug '07

HI Timo & all. We're an mbox environment, inboxes in /var/mail/$USER (I'll include dovecot -n output at the bottom of this mail). mail_location is set accordingly for deliver. I'd assumed that if the /var/mail/$USER file doesn't exist, dovecot would create it, but we've discovered from experience (and I verified it in mbox-storage.c) that if access(path, R_OK|W_OK) fails--as it does if the file doesn't exist--that dovecot defaults then to delivering in root_dir/inbox. I'm curious why this is. It seems like if the configured INBOX file doesn't exist, dovecot should create it if possible; it's a different case than if, say, the user doesn't have write access to that directory, in which case it of course would be appropriate to fall back to some other location rather than rejecting mail. Is there something I'm missing that makes my idea wrong?

[Dovecot] High cpu usage OpenSolaris
by Gary Gendel 01 Aug '07

01 Aug '07

All, Nevermind... I discovered the problem. It was in the Solaris Sun Studio 12 compiler. I created a debug version to begin testing, but that version worked without sucking up the cpu. So it looks like the optimizer messed up. If I used the -fast optimization, it sucks up cpu, but with -xO5 all is well. Gary --------------------------------------------------------------------- Hi, I've built 64-bit dovecot 1.0.2 on Opensolaris to replace version 1.0.0rc10. It functions fine, but when I connect, it eats up all available cpu. My guess is that the poll thread is running continuously. Any ideas on what I should do to verify this or does anyone know of a fix? Thanks, Gary

[Dovecot] Missing MIME-Version header in e-mails.

Hi, I notice that in src/lib-mail/message-parser.c, there is a section of code that checks for the presence of MIME-Version before allowing processing of the Content-* headers. Is there a possibility of relaxing this rule? There are some broken mailers, in particular newsletter mailers that do not seem to honour the MIME-Version header, though they do send the Content-Type.

[Dovecot] Mount options and NFS: just checking...
by Mike Brudenell 01 Aug '07

01 Aug '07

Greetings - I'm now in the last couple of weeks before going live with Dovecot (v1.0.3) on our revamped IMAP service. I'd like to double-check about the best mount options to use; could someone advise, please? I have three separate directory trees for the message store, the control files and the index files. These are arranged as follows: Message Store Mounted over NFS from a NetApp filer; filestore quotas are ENABLED. Control Files Mounted over NFS from the NetApp filer; filestore quotas are DISABLED. Index Files Mounted on local disk; filestore quotas are DISABLED. We will have a pair of Solaris 10 servers on which Dovecot 1.0.3 is running. Users are normally directed to their "preferred" server but, if it is unavailable, will go via the other server. Q1. Am I right in thinking that for the Message Store and Control Files I should NFS-mount both of them with the "actimeo=0"? (Or would "noac" be better, which also turns off client write- caching as well as the attribute cache?) Q2. Should I NFS-mount either or both of the Message Store and Control Files with the "noxattr" option to turn off extended attributes? Q3. Which of the filestores should I mount with the "noatime" option? (I understand that for the filer-based NFS mounts this can be done on the filer, as the option isn't available with "mount" for NFS-monted filestores.) Q4. Any other options to use/miss out? Currently my understanding from the list and the NFS page at the Wiki is: A1. Use "actimeo=0" for both Message Store and Control Files. No idea about the need for/impact of using "noac". A2. No idea. A3. Safe to use "noatime" for all three filestores. (I understand Dovecot will use utime() when needed on such filestores, but am not sure if it will work on the NFS-mounted filestores from the filer if access times are turned off at the filer end.) Any thoughts, please?

[Dovecot] mbox bug in 1.0.0

[Dovecot] dovecot-uidlist locking
by Tony Tsang 01 Aug '07

Hi all, I've a dovecot server setup and occassionally clients cannot get mails from their inbox. When I inspect the maildir for that user, there is stale dovecot-uidlist.lock file, and imap process keeps waiting for release of the lock. Is there any other method to perform locking on dovecot-uidlist instead of using dotlock mechanism? It is creating maintenance problems if I need to remove those stale lock files everytime clients hit this problem Tony.

[Dovecot] user name before and after authentication
by François Wautier 01 Aug '07

01 Aug '07

Hi, I am new to dovecot and spend the last few hours trying to configure it to my liking. I am using version 1.0.2 I have a setup where I only have "virtual" mailboxes in various domain ( mydomain.com, mydomain.biz,...). I setup Exim to deliver the email into <some path>/domains/<domainname>/<user> Now I am trying to get dovecot to access those mailboxes I setup LDAP bind authentication against an AD server. it works fine... but I have a problem getting the correct path to the mailboxes. The user logs in as user(a)domain.ext The mailbox path being at <some path>/domains/%n/%u The LDAP module gets the DN for my user and verify that it can binds, and in the process changes the "user" to cn=<real name>,cn=Users,dc=domain,dc=ext There goes my path To make matter worse, the uid and gid are the same for all users and are fixed (exim user and group). Hence cannot be retrieved from AD I tried to use userdb static, but I can't seem to be able to reset "user" to its pre-authentication value userdb prefetch/ldap but I can't set the uid/gid So here are my request for help... Is there a way to set home dir/ mail dir before authentication? Is there a way to reference the pre-auth user name? Is there a way to create arbitrary variables and used them? Is there a way to fix the uid/gid to use to access the mailboxes? Any one of these could probably solve my problem. Any suggestion is most welcome. François

[Dovecot] IMAPs and POP3s poxying
by Jason Russler 01 Aug '07

01 Aug '07

Hi All, I have a polotical situation at work that requires that I off-load mail access to a host other than the one our users have configured in their clients. I don't have access to any of the switching or routing to our hosts, and there's only a 1 to 1 relationship between the proxy I want to set up and the actual mail handler. I was looking at the proxying Howto in the Wiki and was presented with an SQL server requirement to do user/ip address look-ups. In my case, it will always be proxying the same host. How would I configure Dovecot to proxy another single system without doing the SQL look-up? Is there a port-forwarding solution that would work better (for POP3s and IMAPS)? These are RedHat 5 hosts so Netfilter is fair game if the protocols allow. Thanks, -Jason

[Dovecot] apparent bug with filesystem quota and message lists
by Stewart Dean 01 Aug '07

01 Aug '07

Don't know if anyone else uses Berkeley derived filesystem quota, but IBM's AIX does. A little over a week after migrating from UWIMAP to DC (with mbox format unchanged) everything is clean except for this one problem: When users go over quota, when they login the next time, the folder list is blank. You can imagine the panicked calls to the Helpdesk. If their quotas are raised or re-graced, Get Mail returns the expected list. This behavior happens with a variety of clients: Pine, MacMail,TBird, Horde Webmail, etc. The index filesystem has no quota on it. I would have to imagine the Dovecot is using (or trying to use) some space in the quota'ed filesystems which the operating system won't allow, and this results in there being an empty file that DC uses for the message list sent to the client. There are NO messages in syslog (other than the expected login and logout) indicating any problems. Our legacy setup has the inboxes in /var/spool/mail, and the folders in ~/mail. The problem can happen either place. dovecot -n returns: > # 1.0.1: /usr/local/etc/dovecot.conf > listen: *:143 > ssl_listen: *:993 > disable_plaintext_auth: no > login_dir: /var/run/dovecot/login > login_executable: /usr/local/libexec/dovecot/imap-login > login_processes_count: 12 > login_max_processes_count: 774 > verbose_proctitle: yes > first_valid_uid: 200 > mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u:INDEX=/var/dcindx/%u > mbox_dirty_syncs: no > mbox_lazy_writes: no > auth default: > passdb: > driver: pam > userdb: > driver: passwd Suggestions? -- ==== 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] Dovecot won't build against recent version of GnuTLS
by Jasper Bryant-Greene 01 Aug '07

01 Aug '07

Hi all, Dovecot won't build against recent versions of GnuTLS. The problem starts on line 34 of src/master/ssl-init-gnutls.c, where Dovecot generates DH params using gnutls_dh_params_generate(), a function which no longer exists [replaced with gnutls_dh_params_generate2()]. I'd fix it myself, but the signature of the function has changed to take gnutls_dh_params_t rather than prime & generator, and I'm not keen on hacking SSL code unless I really understand what's going on. It looks like the code goes on to save & free those values. I'm tracking HG and am happy to test any changes. Appreciate it if someone with more knowledge of GnuTLS and perhaps this code in particular could take a look. Thanks, J

[Dovecot] pop3 connections hanging
by Arjun Datta 01 Aug '07

01 Aug '07

Hi, dovecot --version 1.0.beta8 dovecot -n login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd It is running with sendmail-8.13.5-3 on FC5 2.6.15-1.2054_FC5 I find that occasionally a pop3 connection will just sit there for hours on end. It will not release the lock on the user mailbox and so mail to that user cannot be delivered. As a result the mailq backs up mostly with mail to that user. Closing the MUA does not help. I have to kill -9 PID the process to clear the hung connection. This happens with both Outlook and Thunderbird. Is there an option in the dovecot configuration that I can set to automatically close connections after say 30 minutes ? In the workaround section it says that it will close connections from Outlook & Outlook Express after 30 minutes dues to an IDLE bug in those 2. Regards, Arjun Datta

[Dovecot] Dovecot LDAP schema?
by Hadmut Danisch 30 Jul '07

30 Jul '07

Hi, does dovecot define its own LDAP schema or should I create my own one? (I want to provide IMAP boxes for virtual users that do not have a Unix account on the mail server and thus do not want to use the plain uid/gid entries of the posix account objectclass to avoid confusion and accidently giving access to accounts.) regards Hadmut

[Dovecot] High cpu usage OpenSolaris
by Gary Gendel 29 Jul '07

29 Jul '07

Hi, I've built 64-bit dovecot 1.0.2 on Opensolaris to replace version 1.0.0rc10. It functions fine, but when I connect, it eats up all available cpu. My guess is that the poll thread is running continuously. Any ideas on what I should do to verify this or does anyone know of a fix? Thanks, Gary

[Dovecot] Shared mailboxes (maildir, symlinks) and permissions
by Andreas Ntaflos 28 Jul '07

28 Jul '07

Hello list, I am trying to set up a public mailbox for users to put spam in so that sa-learn can do its job at night. Only I can't seem to fully understand how and which permissions should be set. I've read [1] and am using Dovecot 1.0.1. First some background information: I do not host or care (at the moment) about virtual users or virtual mail hosting. All users have Unix system accounts and shell access. I'd like to have a Spam folder, say /var/mail/public/.Spam that is a maildir where users can put Spam that got through the server-side filter. Spamassassin's sa-learn runs nightly and learns from the contents of the Spam folder. After reading [1] I think I should have under /var/mail/public a file called dovecot-shared that belongs to root:mail and has permissions 0660 (with user dovecot being a member of group mail) so that it looks like this: root@host:/var/mail/public# ls drwxr-sr-x 2 root mail 4096 2007-07-28 03:29 . drwxrwsr-x 3 root mail 4096 2007-07-28 02:19 .. -rw-rw---- 1 root mail 0 2007-07-28 02:46 dovecot-shared root@host:/var/mail/public# The first question arises: should Dovecot have write access to /var/mail/public itself? Now I should create the Spam folder called /var/mail/public/.Spam. Should this directory be in maildir format, i.e. should it already contain the subdirectories cur, tmp and new? What of the permissions of this directory? I am pretty sure Dovecot needs write access to it, so it should look like this: root@host:/var/mail/public# ls drwxr-sr-x 3 root mail 4096 2007-07-28 03:44 . drwxrwsr-x 3 root mail 4096 2007-07-28 02:19 .. -rw-rw---- 1 root mail 0 2007-07-28 02:46 dovecot-shared drwxrwsr-x 2 root mail 4096 2007-07-28 03:44 .Spam root@host:/var/mail/public# The .Spam directory here is completely empty. Now in a user's Maildir (/home/user1/Maildir) there are the user's private folders; a symlink to /var/mail/public/.Spam should be added: root@host:/home/user1/Maildir# ln -s /var/mail/public/.Spam . root@host:/home/user1/Maildir# ls ... drwx------ 5 user1 user1 4096 2007-07-19 16:14 .INBOX.foo drwx------ 5 user1 user1 4096 2007-07-06 23:01 .INBOX.bar ... lrwxrwxrwx 1 user1 user1 22 2007-07-28 03:51 .Spam -> /var/mail/public/.Spam ... root@host:/home/user1/Maildir# Is that all I have to do? Probably not, because I keep getting errors like the following when connecting (after subscribing of course): Jul 28 03:52:35 host dovecot: IMAP(user1): mkdir(/home/user1/Maildir/.Spam/cur) failed: Permission denied Should I have created the cur, tmp and new subdirectories manually and set their permissions like /var/mail/public/.Spam? But that still wouldn't give user1 write access. If I gave the users (or "others": chmod o+w) write permissions then Dovecot's index files would be owned by the first user that connects to the server and uses that folder. Apparently also not a solution. I also don't think I should have to make my users members of the mail group, but I could be wrong here. So I am not sure what I am missing, or if what I want to do is at all possible (without taking out the sledgehammer and setting all permissions to 0777). I also apologise for this lengthy post with many details and little interesting questions. It's getting late and I fear I've reached a dead end. I'd really appreciate it if someone knowledgeable could point me in the right direction here. Thanks in advance!

[Dovecot] auth_cache_...
by Frank Elsner 26 Jul '07

26 Jul '07

Hello, the dovecot-example.conf states: # Authentication cache size in kilobytes. 0 means it's disabled. # Note that bsdauth, PAM and vpopmail require cache_key to be set for caching # to be used. #auth_cache_size = 0 # Time to live in seconds for cached data. After this many seconds the cached # record is no longer used, *except* if the main database lookup returns # internal failure. We also try to handle password changes automatically: If # user's previous authentication was successful, but this one wasn't, the # cache isn't used. For now this works only with plaintext authentication. #auth_cache_ttl = 3600 auth_cache_size = 0, does it mean "cache can grow ad infinitum" or does it mean "no cache at all" ?

[Dovecot] Vacation message functionality
by Charles Marcus 25 Jul '07

25 Jul '07

Hi, Since I will soon be attempting to get this working on one of my client's systems, I posed a question on the postfix list - since they mostly dislike vacation messages - but *ardent haters* of badly configured vacation message systems - as to the quality of the dovecot vacation message function. The only response I got did seem to have a few very good suggestions for additional conditions to test for, so I'm posting the response here to see if they can be incorporated (I'm not a coder or I'd attempt it myself). The original text (prefixed by double quote characters) in the following exchange is what I copied/pasted from the wiki, and the reply (prefixed by one quote character) is the suggested change/enhancement (this reply is from a trusted source on the postfix list): >> Vacation auto-reply >> >> The vacation replies are sent to the envelope sender. Currently this >> is taken from the Return-Path: header in the message. > comment: > or from the command line if this is supported. > > also, if the envelope sender is not available, no reply should be > sent. >> List of autoreplied senders is stored in .dovecot.lda-dupes file in >> user's home directory. When you're testing the vacation feature, it's >> easy to forget that the reply is sent only once in the number of >> configured days. If you've problems getting the vacation reply, try >> deleting this file. If that didn't help, make sure the problem isn't >> related to sending mails in general by trying the "reject" Sieve >> command. > if you support extensions, you can test using a unique sender each > time: foo+12345(a)domain.example. >> The automatic replies aren't sent if any of the following is true: >> >> <snip> >> >> o begins with "owner-" (case-sensitive) > replace with: > o starts with "${token}-" (not case sensitive), where token > is one of: owner, request, bounces > > It is safer to send nothing than send a risky one. >> o contains the string "-request" anywhere within it >> (case-sensitive) > replace with: > o contains "-${token}@" (not case sensitive), where token is > one of: owner, request, bounces >> * The envelope sender and envelope recipient are the same >> * The envelope recipient is not found in the message To:, Cc: or >> Bcc: fields. > add: > * There is a "Sender:" header containing one of the tokens listed > above. > * There is a List-Id or List-Post header > * There is no header suggesting that this is possible spam > > Unlike delivery, safety here is to not send a reply if the message > may be spam. so you don't rely on recipient preferences, and you > don't fear false positives too much (the guy who receives your > auto-rep may have a better filter, and besides annoying him, would > find you stupid to miss an obvious spam ;-p) >> The envelope sender is taken from a Return-Path: header in the >> message.

[Dovecot] Thunderbird body search and multiple imap process
by Oliver Schulze L. 25 Jul '07

25 Jul '07

Hi, I'm having an issue with dovecot and Thunderbird and it is reproducible all the time. You do many body search from TB and you end up with multiple imap processess consuming all the CPU and with linux load 20+ Setup: - Centos 4.5 - Thunderbird 2.0.0.5 - Dovecot 1.0-7_53.rc29 and 1.0.1-1_58.el4 How to reproduce: - have an imap account in Thunderbird with 12000+ emails - user maildir in dovecot - do a: ps auwx|grep user1|grep imap|wc -l - in the main window of TB, in the sarch box select "Entire Message" - search one random word and wait 30 seconds - search another random word and wait 30 seconds - search another random word and wait 30 seconds - search another random word and wait 30 seconds - do another: ps auwx|grep user1|grep imap|wc -l - watch that the user1 have now more imap process - watch the linux load, it just rocketed from 1 to 20 - killall -9 imap - watch the linux load return to 1 I'm thinking its TB fault, anyone has seen this issue too?

I'm just curious to know > what your motivation is. Why is it evil? Why do you hate it? EXPUNGE command is specified to expunge the mails, not move them to another mailbox. This would make having the message really gone a 4 stage operation: Mark deleted, expunge, mark deleted in Trash, expunge Trash. In many clients when you mark a message deleted it also copies it to Trash. So a server side expunge-to-trash feature causes the message to get copied there twice. A Trash mailbox also has the problem that all of your messages get there. There's no way to have an easy "unexpunge" operation, because the original mailbox isn't saved anywhere. You have to manually copy the message to the wanted mailbox. Perhaps lazy-expunge is a bit similar, but it preserves the mailboxes and doesn't conflict with clients' move-to-Trash feature. Also the concept in general is about having easily restorable backups of mails and not some kind of a idea that mails should go to a Trash mailbox when they're deleted. Maybe that whole Trash concept is the reason I consider it evil. I don't like that Trash concept in desktop environments either. I wish the undelete feature was in filesystems, so that when disk is full, the oldest deleted files would automatically get overwritten with new data, but until then the files would be undeletable. >> I think having a virtual Trash mailbox that contained all messages >> marked >> as deleted in all mailboxes would be a good solution for this. > > That's not quite the same thing.

[Dovecot] Quota plugin, Maildir, dict backend loop problem
by David Jonas 25 Jul '07

25 Jul '07

Hello, I've been working with the quota plugin(s) the past few days and have been having some real trouble. Only a few entries are appearing in the database, a couple more when I restarted dovecot. None of the current entries were being updated either. I think I've tracked it down to somewhere in the dict backend. I put in a few i_info() statements and recompiled. A few queries get through, then it seems to try the same query about three times and then no new more queries at all (the i_info is right after the allocation of the query string). I couldn't find any errors in the log. An strace of the dict pid shows the following loop. Dovecot -n to follow as well. A quick tcpdump showed a loop something like this: < SELECT current FROM quota WHERE ... > 513965019 < BEGIN < INSERT INTO quota (current, ... < COMMIT > ??

[Dovecot] qpopper -> dovecot migration : which pop3_uidl_format?

Hello, I have read in lots of places about how I should use pop3_reuse_xuidl = yes to prevent pop3 users having to re-download mail (and duplicate their e-mail) after a migration. This fails with the message: pop3_uidl_format setting is missing from config file Which setting for pop3_uidl_format should I set to prevent the e-mail being downloaded again?

[Dovecot] v1.1 alpha1: can't pop/imap login with LDAP
by Katsu Yamamoto 25 Jul '07

25 Jul '07

Hi, We recentlty upgraded our dovecot from v1.0.2 to v1.1ahpha1 under CentOS 4.4. Also, we are using Postfix 2.4.3 and OpenLDAP 2.3.35. We've been using LDAP for our POP/IAMP user authentication, however after upgrading to v1.1alpha1, LDAP authentication does't seem to be working properly. We re-examined the source code, and made a few modification. We are suspecting that... (1) db-ldap.c is not handling value properly?? (2) userdb-ldap.c is not allocating memory for userdb_reply?? The modification we made are following: *** src/auth/db-ldap.c.orig Thu Jul 12 10:42:49 2007 --- src/auth/db-ldap.c Tue Jul 24 20:20:31 2007 *************** *** 55,60 **** --- 55,62 ---- BerElement *ber; string_t *var, *debug; + + int value_index; }; #define DEF_STR(name) DEF_STRUCT_STR(name, ldap_settings) *************** *** 764,769 **** --- 766,772 ---- ctx->vals = ldap_get_values(ctx->conn->ld, ctx->entry, ctx->attr); ctx->value = ctx->vals[0]; + ctx->value_index = 0; } static void *************** *** 797,804 **** db_ldap_result_change_attr(ctx); } else { /* continuing existing attribute */ ! if (ctx->value != NULL) ! ctx->value++; } if (ctx->value != NULL) { --- 800,806 ---- db_ldap_result_change_attr(ctx); } else { /* continuing existing attribute */ ! ctx->value = ctx->vals[++ctx->value_index]; } if (ctx->value != NULL) { *** src/auth/userdb-ldap.c.orig Thu Jul 12 10:42:49 2007 --- src/auth/userdb-ldap.c Tue Jul 24 20:33:45 2007 *************** *** 37,42 **** --- 37,44 ---- struct db_ldap_result_iterate_context *ldap_iter; const char *name, *const *values; + auth_request_init_userdb_reply(auth_request); + ldap_iter = db_ldap_result_iterate_init(conn, entry, auth_request, conn->user_attr_map); while (db_ldap_result_iterate_next_all(ldap_iter, &name, &values)) { With the modification, LDAP authentication is working without any problem, at least for our system. However we are not sure whether the above modification affect other functions of dovecot. Is there an official patch to fix the problem already released? And somehow we missed it? If there is no patch, then will there be any to be released sometime in near future?

The Dovecot Wiki is quite clear regarding its vacation auto-reply mechanism http://wiki.dovecot.org/LDA/Sieve and under what circumstances the automatic replies will NOT be sent. However, is it possible to manually add a list of envelope senders that the script will not respond to? Thank you, B. Bodger

Hi, I wish to setup a shared folder where everyone can read and copy. How does that work? Does each user get their own index file to determine weather a mail i read or not? can users move or copy mail? Thanks in advance Best regards - Jon

[Dovecot] Dovecot using more than one NIC
by Andrew Petrushanco 23 Jul '07

23 Jul '07

I'm am trying to run dovecot on a Fedora 6 Install with multiple IP's but Dovecot (POP3) seems to only function correctly on the 1st NIC/IP. It seems to be responding OK if you telnet to the 2nd or 3rd IPs, but Email clients timeout. >From dovecot.conf protocol pop3 { listen = *:110 } Any suggestions please? Andrew

[Dovecot] v1.1.alpha1 released
by Timo Sirainen 21 Jul '07

21 Jul '07

http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha1.tar.gz http://dovecot.org/releases/1.1/alpha/dovecot-1.1.alpha1.tar.gz.sig This is the first alpha release of Dovecot v1.1. I hope that it stabilizes into final release within a few months. There are a lot of new features since v1.0. The most important ones are listed at the end of this post. This is the only v1.1.alpha announcement I send to dovecot-news list (or to www.dovecot.org news). The next one probably will be v1.1.rc1. I've been stress testing the code a lot and I've also been using it myself for almost a year, so I think this release should actually be quite stable and usable. But since I haven't tested everything, there might be some crashes and misbehaving commands. So this release should now have all the major features that I intend to add to v1.1 (except for dbox rewrite, see below). Some smaller features will still be added. The rest of the major features in my previous v1.1 list will go to v1.2. While v1.1 is getting stabilized I'm beginning to rewrite dbox code. Its code is isolated from the rest of Dovecot, so it can't destabilize anything else. Hopefully it will be ready before v1.1 release, although maybe still marked as experimental. Some of the features might not be considered quite ready yet: - Mailbox list indexes improve STATUS performance a lot (maybe 7x) when mailboxes haven't changed. Handling updates however is a lot slower than I'd want (2x with one client, more with multiple), so you may want to disable them with mailbox_list_index_disable=yes until the update performance gets better. - THREAD code is completely rewritten with support for incremental updates and index files. I tested it last year and it seemed OK, but I didn't dare try it now so I wouldn't have to delay this alpha if it was broken :) I'll do some more testing soon, but for now be careful with using v1.1 with webmails. - SORT code also uses indexes now, but it's a lot simpler so it probably works. - Squat indexes work and I'm using them myself, but they'll be rewritten for v1.2 with a new faster format. - Although Dovecot now flushes NFS attribute/data caches when needed, I'm not sure if it's done in all the necessary places. - I don't remember if I've tested expire plugin at all. So, the largest changes I've added to NEWS file (which BTW won't contain changes between alphas/betas/rcs, those will be only in my mailing list posts): * After Dovecot v1.1 has modified index or dovecot-uidlist files, they can't be opened anymore with Dovecot versions earlier than v1.0.2. * Empty passwords in passdb doesn't allow user to log in with any password anymore. To do that you'll also need to set nopassword extra field. + IMAP: Added support for UIDPLUS and LIST-EXTENDED extensions. + IMAP SORT: Sort keys are indexed, which makes SORT commands faster. + IMAP THREAD: Threads are indexed into a dovecot.index.thread file. It can usually be updated incrementally, so this makes THREAD fast. + Added Dovecot-specific X-REFERENCES2 threading algorithm. It's similar to REFERENCES, but it doesn't do base subject merging and it sorts the threads by their newest message. + When saving messages, update cache file immediately with the data that we expect client to fetch later. Maildir-only currently. + NFS attribute and data caches are are flushed whenever needed. See mail_nfs_storage and mail_nfs_index settings. + Mailbox list indexes. Mailbox metadata is stored there, so STATUS commands can return synchronized mailboxes' metadata simply by reading a single mailbox list index file. Currently works only with Maildir++ layout. + Out of order command execution (SEARCH, FETCH, LIST), nonstandard command cancellation (X-CANCEL <tag>) + Expire plugin can be used to keep track of oldest messages in specific mailboxes. A nightly run can then quickly expunge old messages from the mailboxes that have them. The tracking is done using lib-dict, so you can use either Berkeley DB or SQL database. + Namespaces are supported everywhere now. + Full text search indexing support with Lucene and Squat backends. + OTP and S/KEY authentication mechanisms (by Andrey Panin). + mbox and Maildir works with both Maildir++ and FS layouts. You can change these by appending :LAYOUT=maildir++ or :LAYOUT=fs to mail_location. + LDAP: Support templates in pass_attrs and user_attrs + Support for listening in multiple IPs/ports. + Quota plugin rewrite: Support for multiple quota roots, warnings, allow giving storage size in bytes or kilo/mega/giga/terabytes, per-mailbox quota rules.

[Dovecot] Slower than Courier-IMAP
by Nejc Škoberne 20 Jul '07

20 Jul '07

Hello, I have been running Courier-IMAP for while now, and I decided that I'd like to try Dovecot. This paper: http://student.iu.hio.no/~s132278/reports/disney_imap_maildir.pdf says that the performances are somewhat comparable, but my Dovecot "feels" slower than Courier-IMAP. I am using Maildirs and I have substantial amounts of emails in them. For example one of the folder has 26000 messages and to display a message it takes 6-7 seconds. Before it took only 2-3 seconds to display a message (in Thunderbird). I have tried to turn "fsync_disable" to yes, but the feeling is somewhat the same. What else can I try to tune? It's a FreeBSD 6.2 machine on a HP ProLiant ML350 with 2GB RAM and 120GB SATA disk and the Dovecot running in a FreeBSD jail. You can find my dovecot.conf here: http://pastebin.ca/627442 Thanks, Nejc

[Dovecot] Quota warning patch and config parsing in 1.0.2
by Doug Council 20 Jul '07

20 Jul '07

Dovecot 1.0.2 patches and compiles fine with the quota warning patch (http://www.dovecot.org/patches/quota-warning.patch) But, when parsing the configuration file , deliver now seems to strip all of the spaces in the QUOTA_WARNING environment variable, generating an error. This is the plugin{} section from my dovecot.conf: plugin { quota = maildir:storage=20480 quota_warning = storage=10% /usr/local/bin/quota-warning } And this is the error Dovecot generates for anyone with a quota: quota warning: No command specified: storage=10/usr/local/bin/quota-warning Doing a diff on src/deliver/deliver.c between 1.0.1 and 1.0.2 show some changes to how the config file is parsed, but nothing I can find that would cause the spaces to get stripped out of the configuration value. Has anyone successfully used the quota warning patch with 1.0.2? Thanks, -Doug

[Dovecot] telnet connection refused
by Neil Robins 20 Jul '07

20 Jul '07

I'm running Dovecot 1.0 with Postfix and Amavisd-new on FreeBSD 2.6-RELEASE. Mail was working OK until I put a new mailbox on but then it stopped. Dovecot appears to be running but it doesn't show up in "Top" nor when I run "ps -aucx". I also can't telnet to it on port 110 either at localhost or at the mail server (Connection refused). Can telnet to port 25 (Postfix) no problem. Any suggestions very much appreciated. I know this is an imap group but it's the only Dovecot group I could find. Thanks,

[Dovecot] sluggish updating of gnome mail-notification?
by Greg Troxel 19 Jul '07

19 Jul '07

Sorry if this is a repeat query. I am running dovecot 1.0.2 under NetBSD/i386 (3.1 and 4.0ish). I use maildirs, and deliver into them with procmail. For clients I use Gnus (CVS head) mostly and thunderbird, and also the gnome mail-notification status applet (4.0). Gnus fixed a bug in the last few months where exiting a group didn't unselect the folder and thus didn't necessarily push read marks back. Mostly everything works perfectly. When new mail arrives, thunderbird shows it as new/unread, gnus will find it with 'g', and mail-notification shows it as well. After reading it in gnus, when I exit the group (which pushes read marks to the IMAP server), thunderbird usually shows the message as read immediately, but often mail-notification waits for a while (up to about a minute) before withdrawing the new-mail notification. I just tried this and thunderbird was also slow in showing the mail read. marking the message read in thunderbird caused mail-notification to show the message as read, but with a 30s lag. mail-notification is supposed to use IDLE if available. Sometimes it withdraws new-mail claims at the right time. I know that I need to turn on debugging and trace all this. So I'm really just asking if anyone else has seen this or similar behavior.

[Dovecot] Performance question
by Stewart Dean 19 Jul '07

19 Jul '07

I now have Dovecot in production and things are apparently trouble-free. The one known problem is that initial client inbox load can take 30 seconds - 2 minutes. For instance: 'I got fed up waiting and went and got coffee'...this with a 3MB mbox inbox...and my mail server is a substantial machine consuming 25% CPU just for this person's IMAP session. I realize that a certain amount of performance piggishness is inevitable with large mbox inboxes (the prize goes to the user with a 500MB inbox). Eventually, I plan to move to maildir format, but for now I'm here. Also, we have legacy requirement for procmail, so I can't currently use deliver. Questions: 1) Any tuning I can do to improve this? 2) Any metrics, troubleshooting I should be doing to better characterize the problem? -- ==== 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] Small problem with src/lib/mountpoint.c [now with patch attached!]
by Mike Brudenell 19 Jul '07

19 Jul '07

Greetings - [SIGH: I hit the "Send" button instead of "Attach". Here's Take 2...] Whilst playing with getting quotas from NFS-mounted filestores I've just discovered a slight problem with src/lib/mountpoint.c I had things working on a Solaris 10 test machine which had the mailstore mounted 'normally' using an entry in /etc/vfstab. However when I changed to use the automounter for the mailstore obtaining the quota broke. The problem lies with mountpoint_get(). On a 'normally' mounted filestore this obtains the device_path of the remote filestore in the form remoteservername.some.domain:/remote/path However when the mailstore was automounted I was instead getting back auto_direct which is the name of the automounter map we're using. The /etc/mnttab file has TWO entries for the auto-mounted filestore, like this: auto_direct /mailstore/messages/p autofs direct,ignore,dev=4740014 1184648400 crypt2.york.ac.uk:/vol/vol9/p /mailstore/messages/p nfs proto=tcp,xattr,dev=4700386 1184668792 Although there are two entries they have different device numbers. The mountpoint_get() function attempts to guard against this by checking the device number obtained matches that of the path being located. However for some reason I don't understand when getmntent() returns the FIRST of the above two entries it supplies the device number of the SECOND. Thus the device numbers match in the mountpoint_get() test and it thinks it has found the correct entry. This leads to the device_path being set to the map name -- auto_direct -- instead of the host:/path My fix is to add an additional fstype for the test to ignore: "autofs". The loop skips over any such mounts (along with the existing tests for "swap" and "ignore"). I'm attaching my minimal patch in case it's of help to anyone else. (Timo: would it be possible to get this added into the distribution code if you agree it's right?)

[Dovecot] Integrating dovecot 1.01 into CentOS-3.8 systemw with chroot passwd dirs?
by Gary Goldberg 19 Jul '07

19 Jul '07

Hello. I'm administrating a CentOS 3.8 linux system (RHEL3) and I just replaced the imap-2002d-12 package that came with the system, with a dovecot 1.01 package I obtained through the dovecot home page. The problem I have, is that many of my POP3 users have jailed user accounts set up through wu-ftpd, where the dir field is of the form /home/group/./pop/user, and wu-ftpd chroots them from /home/group but then places them into their home directories, in this case /home/group/pop/user. dovecot can't seem to locate their mail directory.

[Dovecot] production switchover questions

So far so good...other than a my-bad fubar with the permission on the index directory that kept DC from creating index dirs for the entering-for-the-first-time users, quickly noticed (thanks to the excellent logging) and corrected. Some questions 1) the max_mail_processes parm in dovecot.conf...is that *all* processes owned by dovecot? 2) I thought there was a parm to limit how many processes each user can have, but can't seem to find it. Is there any way to control that? -- ==== 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] deleting maildir files
by Tom Bombadil 18 Jul '07

18 Jul '07

Greetings all... Can we delete maildir files directly from the file system? Basically, we use dovecot to train spam, and we want to delete messages that are older than 30 days, using a simple "find /maildirs -cname +30 -name *imap-server* -exec rm {} \;" I have seen a post a while ago saying that dovecot can rebuild the indexes, but I don't remember if it's when the index is deleted or when the maildir files are deleted. And if we cannot delete files with the 'rm' command, whats the best/proper way to delete these older files. Thanks

[Dovecot] A little OT but hopefully still related enough... Maildir Delivered mail naming problems.
by Jesse C. Smillie 18 Jul '07

18 Jul '07

Normally I wouldn't post off topic to a mailing list, but I have posted every where else I can think of and haven't had any success yet working this out. I know there has to be a few people here with extensive knowledge of how mail works and maybe just a tip in the right direction would help me out at this point. I have migrated from mbox format to Maildir format in the last week. I used the utility mb2md.pl to convert all of our existing emails from one system to the next. I then modified my /etc/procmailrc file by putting this at the top: MAILDIR=$HOME/Maildir DEFAULT=$MAILDIR/ This way procmail is forced to deliver to the new format as well. For the most part all of this is working perfectly. Procmail is delivering emails to their new proper folder and even extended rules in users own ~/.procmailrc are working well once the folder path was changed from $MAILDIR/whatever to $MAILDIR/.whatever/. Works great. I am using Dovecot 1.0.1 to deliver our email through the IMAP protocol and with the clients we support (Thunderbird and Outlook) things are working very well for us. So now to my problem. We also use Usermin for our users to access their email when they don't have a supported client available to them. When users look at their email with Usermin their emails are out of order regardless of weather I have Usermin's "Read Mail" module using IMAP to get mail or have it read the users Maildir directly. Sorts are just all jacked up. Sometimes if users then click the "Date" button to sort by date it snaps to; sometimes it don't. I currently have multiple posts on the Webmin/Usermin mailing list about this problem and it really seems to point back to the naming scheme of our emails now. All emails which were converted have the classic maildir format. UnixTime.PID.Server... 1183737827.002379.mbox:2,RS 1183737827.002388.mbox:2,RS 1183737827.002392.mbox:2,RSa 1183737827.002394.mbox:2,RS However, all the email that is delivered after the fact is different. They all look like this: _oTH.XqwlGB.gator:2,RS _p2F.qjVlGB.gator:2,RS _qQF.2mpjGB.gator:2,Sa _sK.8mTlGB.gator:2,RSa _uOG.gCtjGB.gator:2,RS _uxG.a6lkGB.gator:2,RS _vnF.n-2lGB.gator:2, _x9H.llckGB.gator:2, _z3G.k8klGB.gator:2,S _z5G.kAilGB.gator:2,RS I have been searching the net for a few hours and reading various documentation here and there and I haven't been able to find anything that tells me why my mail is being named this way or how to fix it. I can say that my test box which also runs 10.2 slamd also delivers this exact same way.... For the most part I'm being told that the reason why Usermin's sort is all screwed up (order wise) in IMAP mode is that messages are displayed in the order that the IMAP server reports them. Like wise in Maildir mode the order which they are read. I can understand why this naming stuff throws everything off at this point. What I don't understand is why its doing this. I mean I'm pretty sure there is nothing here out of the ordinary as far as my config. I have searched all over the net the last few days and haven't been able to find anything useful. So in wrap up sorry for being a little OT and thanks a head of time for any info or light anyone can share here. -Jesse Smillie

[Dovecot] some mail reappears or marked as read again
by Herbert Gasiorowski 17 Jul '07

17 Jul '07

Sometimes a mail - already read or moved into another folder - appears again in the INBOX. I was not quite sure about this but today is once close the mail client (thunderbird 2.0.0.4 on fedora 7) and the only mail in the inbox was mark as unread. I think it happens in other mailboxes too.

[Dovecot] Small problem with src/lib/mountpoint.c
by Mike Brudenell 17 Jul '07

17 Jul '07

Greetings - Whilst playing with getting quotas from NFS-mounted filestores I've just discovered a slight problem with src/lib/mountpoint.c I had things working on a Solaris 10 test machine which had the mailstore mounted 'normally' using an entry in /etc/vfstab. However when I changed to use the automounter for the mailstore obtaining the quota broke. The problem lies with mountpoint_get(). On a 'normally' mounted filestore this obtains the device_path of the remote filestore in the form remoteservername.some.domain:/remote/path However when the mailstore was automounted I was instead getting back auto_direct which is the name of the automounter map we're using. The /etc/mnttab file has TWO entries for the auto-mounted filestore, like this: auto_direct /mailstore/messages/p autofs direct,ignore,dev=4740014 1184648400 crypt2.york.ac.uk:/vol/vol9/p /mailstore/messages/p nfs proto=tcp,xattr,dev=4700386 1184668792 Although there are two entries they have different device numbers. The mountpoint_get() function attempts to guard against this by checking the device number obtained matches that of the path being located. However for some reason I don't understand when getmntent() returns the FIRST of the above two entries it supplies the device number of the SECOND. Thus the device numbers match in the mountpoint_get() test and it thinks it has found the correct entry. This leads to the device_path being set to the map name -- auto_direct -- instead of the host:/path My fix is to add an additional fstype for the test to ignore: "autofs". The loop skips over any such mounts (along with the existing tests for "swap" and "ignore"). I'm attaching my minimal patch in case it's of help to anyone else. (Timo: would it be possible to get this added into the distribution code if you agree it's right?)

[Dovecot] Problem with Dovecot SASL in Postfix
by Chris McMacken 16 Jul '07

16 Jul '07

Ok lets try this again... I'm trying to configure my postfix server to use Dovecot as an SASL server and running into some problems. My server supports a couple of domain, I have multiple user/password files for multiple domains to make the files a little easier to manage. Not sure if this question should belong in the dovecot mailing list or the postfix one, but here goes anyway. I have everything configured to use CRAM-MD5 authentication, including my mail client.

[Dovecot] Getting quotas from an NFS-mounted filestore
by Mike Brudenell 16 Jul '07

16 Jul '07

Greetings - I was just wondering what the state of play was with regard to reading filestore-based quotas when the mailstore is NFS-mounted? Timo mentioned a little while ago that he'd be including it: http://www.dovecot.org/list/dovecot/2007-May/022594.html However it isn't in 1.0.1 and isn't mentioned in the release notes for 1.0.2. Is it going to be a 1.1 feature or will it appear before then? I'm asking because although I can't get the rquota-rquotad patch to build on Solaris I have found some code on the net which does do RPC based quota lookups. I'm toying with the idea of trying to modify rquota-rquotad to use this other code. However this is out of my area of knowledge so it will be an uphill battle ... so if reading quotas from NFS-mounted filestores will be coming Real Soon Now I'll probably just wait instead. So any ideas as to timescales, please?

[Dovecot] quota warning - take 2
by Nicolas Boullis 16 Jul '07

16 Jul '07

Hi, About one month ago, I sent a patch to this list to implement warnings when a user is close to reach his quota. I tried to follow Timo's advice to improve my code, and here (at last) is a new patch. Things I did not fix: - This patch is still for dovecot 1.0, as I will need warnings with dovecot 1.0. I may rewrite it for CVS HEAD in the future but can't promise. - I'm still using system() rather than fork()+exec()+waitpid() since I don't know a good time to run waitpid(). Comments are welcome. Timo, will you consider to add this to your unofficial patches? Cheers, Nicolas Boullis

[Dovecot] How to stop POP clients from downloading mail after directory corruption
by Frank Church 15 Jul '07

15 Jul '07

Transferring my email from a Courier server, as well as some corruption in my dovecot installation caused all POP mails to be downloaded again. I surmised that the dovecot-uidlist file was not present in the first instance, and was probably out of sync in the second. Is there a way to do some reindexing and uid-list regeneration that can stop the problem from occurring? - Frank

[Dovecot] More Descriptive Logging Needed
by Joseph D. Wagner 15 Jul '07

15 Jul '07

(Everything herein refers to dovecot-1.0.1.) I'm sorry to say that I've been having troubles with dovecot. While attempting to troubleshoot them, I've found the existing logs to be lacking. In particular, I've had a lot of difficulty with the client<->server connection disconnecting, but the only message I get in the logs is "Disconnected". After dissecting the code a bit, I've found quite a number of places where the code will close the connection logging nothing more than the word "Disconnected", or worse, it will not specify a reason in which case the code in client_destroy() will log the default "Disconnected". Because of this, isolating the offending code has been a bit difficult. (I realize the problem may lie with the client, but I cannot even begin to program a work around until I isolate the exact place and cause of failure.) In an attempt to change the logging to be more descriptive myself, I already changed src/imap/cmd-fetch.c:85 on my own copy of dovecot from: client_disconnect(cmd->client, "Disconnected"); to: client_disconnect(cmd->client, "Disconnected in FETCH"); This makes the logging both more descriptive and more in line with other parts of code, like src/imap/cmd-append.c:50 which already say: client_destroy(client, "Disconnected in APPEND"); As luck would have it, my problem was not in the FETCH command. I'm now looking at the client_read() function in src/imap-login/client.c:318-334. If I'm reading the code right, then "i_stream_read(client->input)" returning "-1" means that the socket/stream is already disconnected, right? In other words, some function attempted to read off of a socket/stream that was already closed, right? If so, shouldn't the client_read() function not have been called in the first place? Please let me know if I'm wrong. I've been banging my head against the wall trying to make sense of all the different code. Any assistance you can offer would be appreciated. Joseph D. Wagner

[Dovecot] problem with subscriptions file version 1.0.1
by Liz 13 Jul '07

13 Jul '07

Hello, I am currently working on a patch to add IMAPdir support to dovecot. (For those who do not know, IMAPdir is exactly like Maildir except that instead of having a folder .foo it would just be foo. The advantage is that the file system is slightly easier to search through without the dot in front of the folders.) The first thing I did was get the configuration file working for Maildir. So I know that the problem has nothing to do with the configuration file. Next I looked through the actual source code to find any place where a dot might be added to the beginning of a folder. It transpired that there is a constant, MAILDIR_FS_SEP_S, which is assigned the value ".". I deleted all the occurrences of this constant, compiled the source code again, and ran into a rather interesting problem. When I try to create a new folder through Thunderbird on a separate machine, the folder is not visible unless I restart Thunderbird. I checked on the machine acting as a server and the folder is created and the subscriptions file is updated, and the dot at the beginning is indeed absent. So I see no reason why this should not work. If I had deleted some of the constants that ought not have been deleted, the subscriptions file would not be readable at all and I would not be able to see the folder when Thunderbird restarts. If there were some sort of deadlock going on with the subscriptions file, one would think that it would not be caused by deleting the constants. I would have run into the problem before editing any of the source code. I know for fact that the only thing different about my source code and the code available for downloading is the deleted constants. If anyone has any ideas, please let me know. If you need more information, please feel free to prompt me for it because I have no idea what might be useful that I have not already provided. Regards, Elizabeth Bermel

[Dovecot] Maildir and Windows NFS server
by Julian Jimenez 13 Jul '07

13 Jul '07

Hi, I want to migrate form Courier to Dovecot. The problem is that our NFS server is a Windows server. We use Debian stable (Etch) and maildir. With Courier, we need to compile from the source, changing the parameter MDIRSEP from ":" to ";", because Windows cannot handle files with this character in their name. Anyone knows the name of the parameter in Dovecot that I need to change to do the same? Thanks in advance. Julián

[Dovecot] Dovecot login failing
by Richard Ellis 13 Jul '07

13 Jul '07

Fedora 7 Dovecot version 1.0.1 Hi All, I've been using a combination of getmail/Dovecot/Squirrelmail for a while now and its all been fine. However, last week when trying to demonstrate how to use Squirrelmail to my wife, her login failed. I then tried mine, which I had used many times before and it also fails. Looking in the logs, Dovecot appears to be trying to add a domain name against the login, instead of just checking that user against the UNIX logins of my machine. I thought at first this was because when I'm away from home, I use a no-ip address to access my mailserver, but it also fails when I'm in the house, or even on the server console. dovecot: Jul 12 12:04:56 Info: imap-login: Aborted login: user=< rick(a)servehttp.com>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff: 127.0.0.1, secured dovecot: Jul 12 12:10:00 Info: pop3-login: Login: user=<rick>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured Anybody any idea how to rectify this? I can't see an option in the /etc/dovecot.conf file to stop it and using auth_default_realm = doesn't seem to make any difference. If I telnet into dovecot using my local username and password, it works fine. Any advice would be most welcome before I break it fiddling. Thanks Rik -- The Truth is out there, does anyone have the URL?

I have a client that I have installed Dovecot 1.0.1 for is having some performance issues. Especially when using IMAP from various Outlook clients. I have TLS installed and all the IMAP connections are secured. I'm wondering is anyone has any recommendations for monitoring dovecot performance. I'd like to try and nail down where the real performance issues are. I suspect outlook, but I want to eliminate Dovecot as the cause of any problems, or, if I have a problem with Dovecot, I want to identify any issues I can and fix them.

[Dovecot] Quota Messages
by Hermann wacker 13 Jul '07

13 Jul '07

Hi @all, First: I'm sorry when my english isn't understandable, please just ask if I messed things up. I switched from Cyrus to Dovecot (Cyrus was on Debian Sarge, Dovecot is now on a Etch) and I'm quite happy with it. There is just one thing that I'm missing in Dovecot. in Cyrus when users reached 90% of their Quota, a message popped up in their Mailclients, telling them to clean up their Mailboxes. Dovecot delivers the quotausage to the Client (I can see in my Thunderbird a small Statusbar), but when you don't look carefully, you will mostly miss the point where you can delete the messages without having a fight with the quotalimit (because mails in trash using the quota). At the moment I'm using "quota = fs" so there is no good way to keep the trash out of the quotathing and that's not the point of my question. The question is: Is there a way where Dovecot (or Postfix) inform the user that his quota is reaching its limit? Or maybe the postmaster, thats not important. The important thing is a way where my mailsystem tells somebody that quotas are reaching their limits. Greetings from Germany Hermann Wacker Dovecot Version: 1.0.rc15 Postfix Version: 2.3.8-2+b1 quotaconf: # /etc/dovecot/dovecot.conf IEffective uid=65534, gid=65534 ILoading modules from directory: /usr/lib/dovecot/modules/imap IModule loaded: /usr/lib/dovecot/modules/imap/lib01_quota_plugin.so IModule loaded: /usr/lib/dovecot/modules/imap/lib02_imap_quota_plugin.so log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_extra_groups: mail mail_location: maildir:%h/mails mail_debug: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: passdb: driver: shadow userdb: driver: passwd

[Dovecot] Quota exceeded messages

When I try to move messages between folders I get 'Quota exceeded' messages. I installed dovecot without any major configuration and accounts are created with PostfixAdmin. Is there some common setting that I must be missing? Version in use is 1.0 rc26 - Frank

[Dovecot] Patches to log imap bandwidth?
by Jason Fesler 13 Jul '07

13 Jul '07

Anyone patch dovecot to syslog bytes transfered during a session or anything of that sort? I'm trying to track down imap bandwidth spikes, and unfortunately the uid (according to ipfw) for the imap port spikes is 0. (Presumably FreeBSD's ipfw accounting is based on who started the app instead of the effective user id?) -- Jason Fesler, email/jabber <jfesler(a)gigo.com> resume: http://jfesler.com "Give a man fire, and he'll be warm for a day; set a man on fire, and he'll be warm for the rest of his life."

[Dovecot] v1.1 status and benchmarks
by Timo Sirainen 13 Jul '07

13 Jul '07

v1.1 plans have changed a bit. I'll release v1.1.alpha1 soon and hope to have a stable v1.1 in a month or two. The rest of the features that didn't make it into v1.1 will go to v1.2. I'll write more about this when v1.1 alpha is released. I also did a bit of benchmarking. v1.1's performance improvements are looking pretty great, it seems to be twice as fast as v1.0. v1.0: Maildir, dovecot-1.0 hg + inotify dotlock wait patch, mmap_disable=yes v1.1: Maildir, dovecot hg, mmap_disable=no cydir: Cydir, dovecot hg, mmap_disable=no 1 client -------- ./imaptest logout=0 seed=1 secs=10 clients=1 Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 30% 5% v1.0: 1 1221 1179 1 2420 3458 323 1934 2419 2552 v1.1: 1 2606 2597 1 5221 7352 688 4181 5221 5489 cydir: 1 4495 4534 1 8960 12786 1216 7224 8959 9434 10 clients ---------- ./imaptest logout=0 seed=1 secs=10 clients=10 Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 30% 5% v1.0: 10 2058 2102 10 4157 6019 1426 3348 4157 4391 v1.1: 10 5029 5072 10 10064 14352 3176 8092 10064 10624 cydir: 10 6332 6393 10 12664 17965 3958 10154 12663 13336

[Dovecot] NFS cache flush tester
by Timo Sirainen 13 Jul '07

13 Jul '07

http://dovecot.org/tools/nfstest.c I wrote a test utility that tests different ways to flush NFS attribute cache and data cache. Please test in your NFS setup and show me the results, so I can make Dovecot v1.1 works well with NFS. Run the test several times (3 should be enough) to make sure the output stays the same, because the attribute cache flushes might incorrectly say "OK". And of course attribute cache must not be disabled for this test to work. If you have other ideas how to flush either cache please tell me and I'll update the test utility. I'd like to have a way to flush the cache without having the NFS client send anything to server. Unfortunately all of the below ways do that. Results for Linux v2.6.15 and v2.6.18: Info: Testing attribute cache.. Info: Attr cache flush fchown(-1, -1): failed Info: Attr cache flush fchown(uid, gid): OK Info: Attr cache flush fchmod(mode): OK Info: Attr cache flush chown(-1, -1): failed Info: Attr cache flush chown(uid, gid): OK Info: Attr cache flush chmod(mode): OK Info: Testing data cache..

[Dovecot] Problem with Dovecot SASL in Postfix
by Chris McMacken 12 Jul '07

12 Jul '07

I'm trying to configure my postfix server to use Dovecot as an SASL server and running into some problems. My server supports a couple of domain, I have multiple user/password files for multiple domains to make the files a little easier to manage. Not sure if this question should belong in the dovecot mailing list or the postfix one, but here goes anyway. I have everything configured to use CRAM-MD5 authentication, including my mail client. Here the auth section of my dovecot conf. auth default { mechanisms = plain cram-md5 passdb passwd-file { # Path for passwd-file args = /usr/local/etc/dovecot/%d/passwd } userdb passwd-file { # Path for passwd-file args = /usr/local/etc/dovecot/%d/passwd } user = root # It's possible to export the authentication interface to other programs: socket listen { client { # The client socket is generally safe to export to everyone. Typical use # is to export it to your SMTP server so it can do SMTP AUTH lookups # using it. path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } heres a sample line from one of the passwd files: chrism:{CRAM-MD5}a67a65704086a046b3f875d1eaac8cb5c6fd13406507fead30d9bcb1bf… and to login through SASL I am trying to use the username chrism(a)example.com when I use the full email address like this to login like this I get this output into my postfix log: Jul 10 18:46:59 mail postfix/smtpd[57343]: connect from unknown[12.244.148.123] Jul 10 18:46:59 mail postfix/smtpd[57343]: NOQUEUE: reject: RCPT from unknown[12.244.148.123]: 554 5.7.1 <chrism(a)gmail.com>: Relay access denied; from=<chrism(a)example.com> to=<chrism(a)gmail.com> proto=ESMTP helo=<[192.168.1.14]> Jul 10 18:47:00 mail postfix/smtpd[57343]: disconnect from unknown[12.244.148.123] (not actually using example.com but I changed it here) heres my smtpd_recipient_restricitons from postconf smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination, permit_sasl_authenticated so when I use the full user name (chrism(a)example.com) it doesn't appear to even attempt logging into the sasl server. If I change it to simply chrism, heres the output: Jul 10 18:50:36 mail postfix/smtpd[57356]: connect from unknown[12.244.148.123] Jul 10 18:50:38 mail postfix/smtpd[57356]: warning: unknown[12.244.148.123]: SASL CRAM-MD5 authentication failed: PDI3NjU4MTE4NDExMTQzN0BtYWlsPg== Jul 10 18:50:39 mail postfix/smtpd[57356]: lost connection after AUTH from unknown[12.244.148.123] Jul 10 18:50:39 mail postfix/smtpd[57356]: disconnect from unknown[12.244.148.123] if I put my user name in as chrism and don't add the @example.com it tried to login but it can't login. anyone have any ideas?

[Dovecot] Fixing lda user_query error introduces new fault in mail delivery

I was getting these errors below and after fixing it delivery errors were introduced dovecot/error_log ============== dovecot: Jul 11 06:19:28 Error: auth-worker(default): sql(user(a)domain.com): User query failed: Table 'postfix.users' doesn't exist deliver(user(a)domain.com): Jul 11 06:19:28 Error: BUG: Unexpected input from auth master: FAIL 1 dovecot: Jul 11 06:21:41 Error: auth-worker(default): sql(admin(a)achimota.com,127.0.0.1): User query failed: Table 'postfix.users' doesn't exist ============== It turns out that using prefetch with dovecot lda required a user_query in dovecot/sql.conf I fixed it by adding this query to dovecot/sql.conf user_query = SELECT concat('/var/vmail/', maildir) as home, 601 as uid, 12 as gid FROM mailbox WHERE username = '%u' AND active = '1' This resulted in a new mailbox /var/vmail/domain.com/user(a)domain.com being created when although /var/vmail/domain.com/user already exists and is what the query returns It seems that prior to that when the query was failing the mail was properly delivered somehow by dovecot, but fixing it created a new problem. It appears that the mail_location = maildir:/var/vmail/%d/%u in dovecot.conf could be related as %u is user(a)domain.com Is there a fix for this?

[Dovecot] Can Wiki entry on dovecot LDA/deliver be clarified?
by Frank Church 11 Jul '07

11 Jul '07

Hi guys, I am having some problems relating to this "Fixing lda user_query error introduces new fault in mail delivery" and I'd like to know if the above wiki comment holds even if a user_query is configured to return the correct mail folder. According to this LDA delivers only to the mail_location setting. Does that mean that it will stick to the value in dovecot.conf or will the value returned in the query override it? This appears to be the problem I am experiencing with the previous thread. >From wiki entry at wiki.dovecot.org/LDA ============================ Problems with deliver Currently deliver doesn't support namespaces. The mails can be delivered only to mailboxes specified by the mail_location setting. If you are using prefetch userdb, keep in mind that deliver does not make a password query and thus will not work if -d parameter is used. The UserDatabase/Prefetch page explains how to fix this. ================================== Any ideas? - Frank

[Dovecot] target doesn't allow inferior mailboxes

Using Seamonkey as my email client, and IMAP to check mail. If I create a new IMAP folder, and then delete it, I get the error: The current command did not succeed. The mail server responded: Target mailbox doesn't allow inferior mailboxes. Tried a google search, didn't really come up with anything. I have rw permissions on /home/awilliam/Mail/* and delete the files fine using rm -rf /home/awilliam/Mail/whatever and editing the folder out of .subscriptions. Any ideas?

[Dovecot] About a simultaneous session of Dovecot(IMAP)
by Takateru Ueda 11 Jul '07

11 Jul '07

The construction of the mail server with Postfix+Dovecot(IMAP) is examined. ・The number of mailboxes is about 1000. ・The reception protocol uses IMAP and the Maildir form. ・OS is Redhat Enterprise Linux ES4. ・MUA uses Outlook Express. ・Postfix and Dovecot use latest Ver. In the above-mentioned environment, it is understanding person. how much the number of maximum sessions (number of people) that can be used at the same time becomes from MUA (When grounds of the calculation are understood, it is the best. )

[Dovecot] Connecting to dovecot/imap without a password
by Don Russell 11 Jul '07

11 Jul '07

I have written a script that connects (localhost) to the dovecot/imap server and performs various maintenance on my mail, by folder..... deleting old stuff, keeping the n most recent, that sort of crap, er good stuff. :-) My script is written in php (I use the various imap_* functions), and it connects to the imap server running on the same machine... is there a way to connect to the server without having to specify my user name and password? I was thinking there may be some form of "implied" logon if a request from user "don" requests to log on to user "don", then there's no need for a password check, when the connection is via localhost. That way I don't have to deal with userid/password related issues. :-) Thanks

Then the resulting mail message I get, has this header: | Return-Path: <MAILER-DAEMON> | Delivered-To: my(a)mail.address.tld | Received: from foo (localhost.localdomain [127.0.0.1]) | by mailserver (Postfix) with SMTP id 673072767C | for <my(a)mail.address.tld>; Wed, 11 Jul 2007 13:36:07 +0200 (CEST) | Message-Id: <20070711113611.673072767C@mailserver> | Date: Wed, 11 Jul 2007 13:36:07 +0200 (CEST) | From: MAILER-DAEMON | To: undisclosed-recipients:; It seems that postfix changes the return-path, and I dont see why it would do something like that. The bounce is not a bounce anymore, and if a user fetches the mail with e.g. fetchmail, and it cannot be delivered, then the bounce will be bounced, to MAILER-DAEMON .. My master.cf entry looks like this: dovecot unix - n n - - pipe flags=DRhu user=atmail:atmail argv=/usr/local/dovecot/libexec/dovecot/deliver -d ${recipient} If I add null_sender= , then that resolves it: dovecot unix - n n - - pipe flags=DRhu user=atmail:atmail null_sender= argv=/usr/local/dovecot/libexec/dovecot/deliver -d ${recipient} What do other postfix/dovecot-users do? Will this change break anything? I cannot see why empty null_sender isn't default .. so I'm wondering if there is something I've missed. Should we update the examples on http://wiki.dovecot.org/LDA/Postfix to include empty null_sender? -- Erland Nylend

[Dovecot] [Patch] Samba's proposed "ntlm_auth + winbind" support for dovecot-auth
by Dmitry Butskoy 11 Jul '07

11 Jul '07

The Samba team recommends to use their "ntlm_auth" command line helper for "NTLM" and "GSS-SPNEGO" authentication. This helper interacts with the Samba's winbind daemon, and this way can authenticate users against NT or Active Directory windows domain. Currently Dovecot can do "NTLM" authentication too, but just "locally" (against a local or sql database etc.). I've made a patch (attached), which adds "ntlm_auth" (or "winbind") support for Dovecot. The idea is to add two new authentication mechanisms: "mech_winbind_ntlm" and "mech_winbind_spnego". Both are coded in one additional file, "mech-winbind.c". An option "auth_ntlm_use_winbind" specifies whether to use the current implementation of ntlm, or do it by the "ntlm_auth" helper. "GSS-SPNEGO" always performed by the helper. Normally, "ntlm_auth" is invoked once, for all further requests. Such a way, "ntlm_auth helper from the Samba package, interacting with the Samba's winbind daemon", is used now by Squid, Apache and AFAIK some other applications. It is "strongly recommended" by the Samba team, and was already proposed even in this maillist 3 year ago (see f.e. http://www.dovecot.org/list/dovecot/2004-September/004775.html ). I hope there are no any serious performance issues for such a "complex way" -- f.e. with our web proxy, using this way, ~200 users do not feel any actual delays etc. I've successfully tested this patch with NTLM against AD domain. This patch can considerably improve the situation of "Email client on Windows desktop under Windows domain, but imap/pop at UNIX server". Currently, windows users have to specify their "login/password" for email accounts manually. There is an "SPA" (Secure Password Authentication) alternative for them, where just the desktop's login is used transparently, but it cannot be used now, because Dovecot cannot perform NTLM against, say, Active Directory domain. Since "dovecot-auth" daemon can be utilized by MTA as well (Postfix and other), the support of "ntlm_auth" in Dovecot can satisfy both SMTP and IMAP servers at UNIX side, and solve the issue completely. Questions and requests: - I try to code things most close to used style, i.e. using Dovecot's memory-management and io-pipe routines etc., but could someone look at it and check whether I've missed something or not? - Perhaps some names (of routines, modules) could be chosen better? - Maybe some other options should be implemented, i.e. "auth_winbind_helper_ntlm" and "auth_winbind_helper_spnego" to specify the helper's cmdline exactly ? - Currently I strip domain part of the username returned, i.e. from "DOMAIN\user" just to "user". Maybe better add some option "auth_winbind_strip_domain" for this? Certainly, it will be fine if someone else check it more, especially for "GSS-SPNEGO" which I cannot test for a while.

[Dovecot] NFS and Filesystem quota
by Joseba Torre 11 Jul '07

11 Jul '07

Hi, I've recently moved my mailboxes to a NFS share (on an emc Celerra), and, as expected, the quota extensions no longer works. However, I've read that adding http://dovecot.org/patches/quota-rquotad.c to $DOVECOT/src/plugins/quota, adding a line to $DOVECOT/src/plugins/quota/Makefile.am and rebuilding, it should work again.

[Dovecot] Migrating subscription lists
by Stewart Dean 10 Jul '07

10 Jul '07

I thought this would be relatively straightforward....I would create .subscriptions by doing an ls -1 of ~/mail. I'm running into some problems. 1) the ~/mail directories haves directories in them for 5% of the accounts! AFAIK, our mail sevice has always been UWIMAP with mbox format INBOXes, and it was my understanding that the mbox format is flat and NOT hierarchical and thus I'd have thought that ~/mail would be all folders and wouldn't have a directory with folders in it. Plus our users are not, as a rule, power/geek user that would understand even making subdirs in ~mail, so I don't know how this would have come to pass. Should this be? Or am I misunderstanding things? 2) Some people are consciously or unconsciously using the UWIMAP .mailboxlist subscription file as it is meant to be used, namely to *restrict* the folders shown. If/when I generated the Dovecot .subsbcriptions file by just doing an ls -1 of their mail directory, they will be surprised to see stuff not previously displayed....that they may very well not know they'd had. Murphy must be a terribly overworked deity...you'd think he'd take a rest now and then from maximizing entropy -- ==== 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] mbox vs maildir
by Don Russell 10 Jul '07

10 Jul '07

I'm using Dovecot 1.0.1-12 on Linux/Fedora 7 along with sendmail and procmail all running on the same box mail is stored in mbox format It's a small system with a half dozen or so e-mail "accounts". Each with 40-60MB of messages in various folders. I keep seeing messages about how mbox is antiquated and anybody with more than 100 messages etc should not use mbox, but use maildir instead. I'm not entirely convinced.... there seem to be pros and cons for each. Is there a discussion somewhere that really highlights why one format is so much better than the other? The last time I tried to convert from mbox to maildir, things got pretty botched up, no data loss, but it wasn't pretty. :-) Can Dovecot handle mbox for some users and maildir for others? I'd like to try a conversion for one user... I'll probably create a new user, then have procmail copy (via ! action code) all mail for one user to that new user. Thank you

[Dovecot] secure pop for outside pop inside
by arjan 10 Jul '07

10 Jul '07

Hi all, I've a server with dovecot running in secure pop mode. For connections from the outside world, I don't want to enable pop. However, this machine is also the host for a vserver. In this vserver I have a webserver running the WebGUI Content Management System. One can add content via email. For this the cms has to be able to check a pop emailbox. The cms doesn't support secure pop. It's not nescessary either, because dovecot and cms are on the same machine. How can I configure Dovecot in such a way that I can enable pop just for one ip-adress and have secure pop for connections on another adress? Any help would be very much appreciated. Kind regards, Arjan

[Dovecot] Tbird-DC state problem
by Stewart Dean 09 Jul '07

09 Jul '07

A experienced sysadmin who's doing some guinea-pig use of DC just ran into the following situation: 1) He brings up SeaMonkey 2) About 30 minutes later, he's in the middle of some involved messaging, mistakenly hits the redX in the top right of the SeaMonkey window, knocking himself out of SeaMonkey. 3) He immediately reinvokes SeaMonkey, all appeared to be OK Viewed some e-mail and some web page references, tries to send a message and then the Send hung for a time with a message "Sending Authenticate Info"..after some minutes, a new E-mail window appeared stating the "Server reported a timeout". As far as the message, it was apparently sent successfully, and saved in the Sent folder successfully. 4) He calls me in. I look through the syslog logging. There is nothing in the syslog critical stuff...and everything in the maillog looks normal. 5) He starts another message, tries to save it to Drafts and that hangs 6) I look more closely at the maillog and see a lot of logins (one a minute in some cases, but all appear to have been cleanly executed) plus one bunch of disconnected messages with one disconnected in idle in the period when the write to the Drafts would have been hung. Could it be that DC was in the middle of clean up in the initial disconnect/reconnect and SeaMonkey came back in the middle of it and one or the other's state tables got messed up (or both of them)? Shutting out of SeaMonkey, waiting a minute and reconnecting seems to have gotten things working again. Any comments? Anything I should be looking for? OTOH, this is the first real problem I've seen in some person-months of testing..... -- ==== 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] PHP implementation of dovecotpw passwords
by Frank Church 09 Jul '07

09 Jul '07

I am looking for PHP functions that implement passwords that much the dovecotpw implementation. I downloaded one from PEAR, Crypt_HMAC, but the passwords it generates look nothing like the dovecotpw passwords, which could be my fault because I know nothing about the field. Is there a guide or some library that implements them to match dovecotpw?

[Dovecot] Virtual servers
by John Hedges 06 Jul '07

06 Jul '07

Hello I'm migrating from Courier to Dovecot (1.0.rc15) on Debian. I am trying to set up virtual servers based on the principal in this thread: http://www.dovecot.org/list/dovecot/2006-October/017165.html which suggests something like this to support multiple certificates: server foo { listen = 1.2.3.4 ssl_cert_file = /etc/ssl/certs/foo.cer } server bar { listen = 1.2.3.5 ssl_cert_file = /etc/ssl/certs/bar.cer } My virtual configs look like this: server mail.domain1.org { listen = 1.2.3.4 protocols = pop3 pop3s imap imaps ssl_cert_file = /etc/mail/hosts/domain1.org/ssl.crt ssl_key_file = /etc/mail/hosts/domain1.org/ssl.key auth default { mechanisms = plain passdb passwd-file { args = /etc/mail/hosts/domain1.org/userdb } userdb passwd-file { args = /etc/mail/hosts/domain1.org/userdb } } } server mail.domain2.org { listen = 1.2.3.5 protocols = imap imaps ssl_cert_file = /etc/mail/hosts/domain2.org/ssl.crt ssl_key_file = /etc/mail/hosts/domain2.org/ssl.key auth default { mechanisms = plain passdb passwd-file { args = /etc/mail/hosts/domain2.org/userdb } userdb passwd-file { args = /etc/mail/hosts/domain2.org/userdb } } } but I can't get ithis to work. Dovecot starts but authorisation fails. Is this kind of setup possible - is it possible to configure different passwd-files for connections on different IPs, or am I going to have to run separate instances of Dovecot for each virtual host? Thanks John

05 Jul '07

The day I switch our user to dovecot and it goes into production, there will be a few thousand people all generating their indices for the first time (we have a legacy requirement for procmail, at least for now), so I wondered: 1) Is there is anyway to pre-emptively force indexing? 2) Is there any value in doing so? That is, will I gain much in terms of making the first time everyone connects to dovecot quicker (not that big initial wait)? -- ==== 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

Removing the spurious /etc/passwd entry (and fixing the local file ownerships) gets rid of the permission problems. Thanks for your help.

[Dovecot] Permission errors when creating/reading files in users' mail directories
by Bryan Wright 05 Jul '07

05 Jul '07

Hi folks, I'm trying to migrate an old uw-imap server to dovecot, and running into puzzling (to me) permission problems. I've configured mail_location as follows: mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u and each user's mail directory has permissions like this: drwx------ 2 uid gid 4096 Jul 5 09:26 /home/uid/mail But when I try to check a user's mail using an imap client, I see the following error: Jul 5 09:59:49 imap dovecot: IMAP(uid): mkdir_parents(/home/uid/mail/.imap/ INBOX) failed: Permission denied If I open up the permissions so anyone can write, I find that the .imap directory is successfully created, and owned by "uid". Is dovecot initially creating the directory with some other ownership, and then changing the ownership to "uid"? I can get around this problem by setting INDEX in mail_location, and pointing it to a directory with more open permissions, but then I run into the next problem: Jul 5 09:25:49 imap dovecot: IMAP(uid): open() failed with mbox file /var/spool/mail/uid: Permission denied In this case, the permissions are set as follows: -rw------- 1 bkw1a mail 1267 Jul 5 08:47 /var/spool/mail/uid How should the permissions be set on the spool files? Thanks in advance, Bryan -- ======================================================================== Bryan Wright |"If you take cranberries and stew them like Physics Department | applesauce, they taste much more like prunes University of Virginia | than rhubarb does." -- Groucho Charlottesville, VA 22901| (434) 924-7218 | bryan(a)virginia.edu ========================================================================

[Dovecot] dovecot.conf pop3_uidl_format
by Peter Eriksson 05 Jul '07

05 Jul '07

From the Dovecot 1.0.1 sample dovecot.conf file: # If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu ... # Note that Outlook 2003 seems to have problems with %v.%u format which was # Dovecot's default, so if you're building a new server it would be a good # idea to change this. %08Xu%08Xv should be pretty fail-safe. # # NOTE: Nowadays this is required to be set explicitly, since the old # default was bad but it couldn't be changed without breaking existing # installations. %08Xu%08Xv will be the new default, so use it for new # installations. # pop3_uidl_format = %08Xu%08Xv Notice the *very* small difference in the format between UW's ipop3d and the ones mentioned a little bit below? I think I just got bitten by this (we moved from UW's ipop3d to Dovecot). Loooots of users just got a lot of new (old) mail again ("Leave mail on server" is a popular setting). Ah well. They really should move to IMAP anyway and now they got some summer reading to do :-) Is the difference intentional? If so then perhaps this should be more clearly pointed out! - Peter

[Dovecot] dotlock O_EXCL query
by derek kit hoong foo 05 Jul '07

05 Jul '07

Hi there, I was wondering if someone can assist with clarifying why O_EXCL does not always work with NFS. Is it related to NFS protocol version support or export permissions mode out of the Celerra/Netapp ( e.g: mixed mode, unix file permissions ? ) Please advise. Thanks. Regards, new dovecot user.

[Dovecot] PAM timed out, kill failed, auth SEGV
by Thomas Arnett 04 Jul '07

04 Jul '07

My log is full of blocks like this: auth(default): pam(?): PAM child process 13576 timed out, killing it auth(default): PAM: kill(13576) failed: No such process Often, this is recorded for several pids at once. Occasionally, there's a single burst when a virtual user logs in, immediately before pam_authenticate() fails and checkpassword is executed. When this happens, pam() contains the username and remote IP. Usually, it starts 2 minutes after a login attempt (successful or not) and repeats every 10 seconds indefinitely. pam() contains something else: ~87% ? ~ 9% [garbage],master ~ 4% ?,master < 1% [empty] [garbage] varies; it seems to be constant for an instance of auth, but I haven't verified this. Eventually, auth segfaults: Core was generated by `dovecot-auth'.

[Dovecot] Maildir configuration vs ZFS and snapshots...
by Peter Eriksson 04 Jul '07

04 Jul '07

I have a little tricky issue around here. First some background: Every user is assigned their own ZFS filesystem, and it's mounted as /home/USER with a Maildir inside it. The there is a filesystem snapshot (read-only) taken automatically every day by the system. The idea is to allow users easy access to backup copies of their mail so that they can restore things themself.. For example this structure (somewhat abbreviated, some files/dirs removed): /home/testson/ .zfs/ snapshot/ 2007-06-18/ Maildir/ cur/ new/ tmp/ .Trash/ cur/ new/ tmp/ Maildir/ cur/ new/ tmp/ .Trash/ cur/ new/ tmp/ Now,I can access the normal Maildir INBOX and folders nicely via Dovecot/IMAP. The thing is I'd like to be able to access the snapshot too via Dovecot/IMAP somehow. My first idea was to use Dovecots namespace feature like this in the config file: namespace private { separator = / prefix = snapshot/ location = maildir:~/.zfs/snapshot/2007-06-18/Maildir:CONTROL=~/.dovecot/control:INDEX=~/.dovecot/index } This works great for the mail folders inside the Maildir - but not for the INBOX which isn't displayed at all... (Ie, under the "snapshot" prefix I only see "Trash" etc when looking at the folder from an IMAP client). I think that I'd need to use the "INBOX=" option for Dovecot to see the top-level "new/cur/tmp" directories in the snapshot folder, but you can only have one INBOX if I'm not mistaken? Any suggestions on how best to configure this? - Peter

[Dovecot] convert plugin: endless conversion and duplicate messages
by Andrew Ziem 03 Jul '07

03 Jul '07

Hi, When an mbox has a filename with a period, the Dovecot 1.0.1 convert plugin will endlessly convert the same mbox causing duplicate messages. To reproduce, create try converting two mboxes: one with a valid name and another with an invalid name. Then, repeat the login procedure a few times. Dovecot should do something more graceful such as replacing periods with another character. Here's /var/log/mail/errors Jul 2 08:29:44 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 08:39:46 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 08:48:54 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 08:48:58 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 08:49:39 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 08:59:40 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 09:09:40 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 09:20:23 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name I didn't test other non-{alphanumeric,whitespace} characters. Other than this and my previous e-mails, our conversion from UW-IMAP mboxes went nicely. I notice the performance difference, and our users will be happy to finally have proper subfolders. Andrew

[Dovecot] listen parm questions
by Stewart Dean 03 Jul '07

03 Jul '07

Q1: My imap server has 4 interfaces, but only one is used for imap traffic. Can I do this: listen = 10.20.30.40:10143 (when imap.mycollege.edu is 10.20.30.40) Or is there even any benefit to doing this? Q2: Can I specify more than one port....during test eval, I've had the IT dept using port 1043 for listen....which I will, of course, change to 143 when DC goes production. So my department isn't cut off by that switchover, can I do this? listen = *:10143,143 or this listen = 10.20.30.40:10143,143 I did look at the wiki but didn't see anything -- ==== 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

Anyone have ideas why this happened? Nothing special in logs, all tss(a)iki.fi deliveries went OK. Mailman's bounce log is unhelpful. Why does it say it tried to deliver to dovecot(a)dovecot.org and when it failed it disabled my account? Why doesn't it even bother saying which remote host gave an error? Grepping mail.log for 'This user' shows nothing.

[Dovecot] Leaky dovecot-auth ?
by Christian Balzer 03 Jul '07

03 Jul '07

Hello, as mentioned before, we are migrating our mailboxes from a 0.99 cluster to a 1.0.0 one. With 0.99 dovecot-auth (with LDAP as backend) was leaking quite happily and the dovecot-auth processes frequently did hit their size limit and thus were killed and restarted. Which in 0.99 at least lead to authentication failures on a busy server, as the dovecot master process just killed off the auth process w/o disabling new connections to it first and letting any current authentications finish. The activity per cluster node on the 0.99 boxes was about 700k logins (mostly pop3) per day and 5 dovecot-auth processes with a 64MB limit each. The migrated users so far are of the less active kind and on one node of the 1.0.0 cluster we see about 70k logins/day and currently the dovecot-auth process there is hovering at 123/84MB (VIRT/RES in top). It was at 121/82MB when I checked 4 hours ago and no new users have been added to that node for 2 days. Authentication backend is still LDAP, no caching, 256MB process size limit. There are just 16k users on that node at this point in time, with only 1200 distinct users generating those 70k logins/day. We will start migrating the rest of the users tomorrow and now I'm wondering: 1. How and why would the memory footprint of dovecot-auth grow when there is no change in the amount of users in the DB? 2. What will happen when the single dovecot-auth process reaches 256MB in the end? Internal housekeeping attempts of that process? A whack to the head from the master process like in 0.99 and thus more erroneous authentication failures, potentially aggravated by the fact that there is just single dovecot-auth process? I guess at the current rate of leakage we shall know the answers to #2 soon one way or another. ;) Regards, Christan -- Christian Balzer Network/Systems Engineer NOC chibi(a)gol.com Global OnLine Japan/Fusion Network Services http://www.gol.com/

[Dovecot] Semi-static userdb...?
by John Robinson 03 Jul '07

03 Jul '07

I'm trying to add "virtual" mailboxes to a system. Real users with different uids own domains. Each domain has a passwd-file passdb. I don't want to use this passwd-file for the userdb, because I want to fix the home, mail and uid/gid settings. Can I use the static userdb in a less static manner, e.g. userdb static { args = uid=%{owner of /vmail/%d} gid=%{gid of /vmail/%d} home=/vmail/%d/users/%u mail=mbox:/vmail/%d/users/%u/mail:INBOX=/vmail/%d/users/%u/INBOX } Or is it just a bad idea to let relatively untrusted domain owners manage their own passwd-file at all...? Cheers, John.

[Dovecot] userdb nss
by Timo Sirainen 03 Jul '07

03 Jul '07

I remembered people complaining how glibc ignores NSS errors with getpwent(), so I thought I'd see how easy it is to use NSS directly. Unless I misunderstood something, this should work: http://hg.dovecot.org/dovecot/rev/c9b49ed99d28 Tested only with "files" backend. Also it won't work with Solaris, it seems to have completely different NSS modules. Don't know about BSDs. Can someone test how it handles LDAP/NIS failures (or if it even works with them)?

[Dovecot] v1.1 max connections per user
by Timo Sirainen 02 Jul '07

02 Jul '07

v1.1 has now: # Maximum number of connections allowed for a user. The limits are enforced # separately for IMAP and POP3 connections, so you can move this setting # inside protocol {} to have separate settings for them. NOTE: The user names # are compared case-sensitively, so make sure your userdb returns usernames # always using the same casing so users can't bypass this limit! #mail_max_user_connections = 10 Is 10 a good default? Currently new connections just fail authentication with a "Maximum number of connections exceeded" error message. v2.0 hopefully will instead disconnect the oldest idling connection with IMAP.

hi, i'm migrating 1 mail-server from LDAP+postfix+courier to mysql+postfixadmin+dovecot, on a debian etch machine i have followed this howto : http://wiki.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL (changed uid and gid for usage in debian, the SVN-postfixadmin didn't work for me, so i used the stable version, and haven't tested the SASL-part yet) this works great, except the LDAP+postfix setup has for some users an automatic Cc: say, for example, 1 user, with email-address jeremy(a)mydomain.org, will also have all the emails going to jeremy(a)gmail.com so far i have failed to find out whether this can be done with postfix in that setup, following above mentioned howto (postfixadmin can do aliases, but not "auto Cc: for virtual domains afaik) can this be done by dovecot LDA maybe ? or ... can i have a dovecot.conf where certain users use LDAP instead of mysql for lookups and those kind of preferences ? grtz, albi

[Dovecot] Differences in deliver and IMAP
by Andy Shellam 01 Jul '07

Hi I've now got Dovecot 1.0.1 authenticating with PostgreSQL for the IMAP service, but deliver doesn't seem to work the same.

Here's the log for a deliver attempt: dovecot: Jul 01 16:51:35 Info: auth(default): master in: USER 1 andy.shellam(a)mailnetwork.co.uk service=deliver dovecot: Jul 01 16:51:35 Error: auth(default): prefetch(andy.shellam(a)mailnetwork.co.uk): passdb didn't return userdb entries dovecot: Jul 01 16:51:35 Info: auth(default): master out: NOTFOUND 1 And here's the log for an IMAP login attempt straight after: dovecot: Jul 01 16:51:46 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip=84.45.66.158 rip=82.165.38.62 resp=AGFuZHkuc2hlbGxhbUBtYWlsbmV0d29yay5jby51awBhYzI5Y2U4NHN5ZA== dovecot: Jul 01 16:51:46 Info: auth(default): sql(andy.shellam(a)mailnetwork.co.uk,82.165.38.62): query: SELECT <user_field> as user, <password_field> as password, <home_directory> AS userdb_home, <mail_directory> AS userdb_mail, <chroot_directory> AS userdb_chroot, <uid_field> AS userdb_uid, <gid_field> AS userdb_gid FROM <user_table> WHERE <user_field> = 'andy.shellam(a)mailnetwork.co.uk' dovecot: Jul 01 16:51:46 Info: auth(default): client out: OK 1 user=andy.shellam(a)mailnetwork.co.uk dovecot: Jul 01 16:51:46 Info: auth(default): master in: REQUEST 1 24949 1 dovecot: Jul 01 16:51:46 Info: auth(default): prefetch(andy.shellam(a)mailnetwork.co.uk,82.165.38.62): success dovecot: Jul 01 16:51:46 Info: auth(default): master out: USER 1 andy.shellam(a)mailnetwork.co.uk home=<home_directory> mail=maildir:<mail_directory> chroot=<chroot_directory> uid=<uid> gid=<gid> dovecot: Jul 01 16:51:46 Info: imap-login: Login: user=<andy.shellam(a)mailnetwork.co.uk>, method=PLAIN, rip=82.165.38.62, lip=84.45.66.158 This works if I use separate userdb and passdb queries. Does deliver not support the prefetch authentication method? Thanks, Andy.

I like 15. That way it is high and isn't as likely to affect existing installations unless they manually set it to something lower. Or if you want to have a separate default for POP vs IMAP, I'd use 5 for POP and 15 for IMAP.

[Dovecot] Copyright notices in code
by Timo Sirainen 30 Jun '07

30 Jun '07

I thought about committing this change to all .c files: Removed all Copyright Timo Sirainen comments. They weren't always correct and the year numbers were rarely updated when something was changed. Copyright is owned by the creator by default in practically all countries, there's no need to advertise it everywhere. Can anyone think of reasons why this wouldn't be a good idea?

[Dovecot] wiki.dovecot.org double-escapes capcha info
by Ben Winslow 29 Jun '07

29 Jun '07

The "capcha" on wiki.dovecot.org seems to be double-escaping HTML entities in the informational message, such that the wiki displays "Captcha to prevent wiki spam, write Dovecot here:" [sic.] When I dutifully entered "Dovecot," it didn't work, saying "You didn't provide the correct captcha. Use the browser's Back button and try again, or register an account to avoid this." [sic] It took a few minutes for me to realize what was going on and simply enter "Dovecot" for the capcha... -- Ben Winslow <rain(a)bluecherry.net>

[Dovecot] dovecot help
by Andy Fadich 29 Jun '07

29 Jun '07

Hello, I have a mail server which I upgraded yesterday. OLD: Redhat 9 sendmail (very old version) UW ipop3d usermin with readmail module for webmail access (very old version) NEW: Fedora Core 6 sendmail 8.13.8 Usermin for webmail again dovecot 1.0.0 # /etc/dovecot.conf protocols: pop3 login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/pop3-login mail_location: mbox:/home/%u/mail:INBOX=/var/spool/mail/%u mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/pop3 pop3_uidl_format: %08Xv%08Xu auth default: passdb: driver: pam userdb: driver: passwd Everything is working great, besides a few glitches here and there. However, When accessing mailboxes via webmail (usermin) an email shows up with a subject of DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA. As far as I can tell, this is an IMAP folder directory portion of the mailbox file that should be hidden. We don't use IMAP at all, and it is confusing people when they see this message that never was in their webmail before. Anyone know how to hide, remove or otherwise fix? Thank you in advance. Andy

[Dovecot] FreeBSD NFS file locking mechanism
by Tony Tsang 29 Jun '07

29 Jun '07

Hi all, I have some machines running FreeBSD and dovecot deployed. User's home dir is on NFS mount and I've found that dovecot only works with dotlock file locking mechanism, fcntl and flock failed. Now it causes problem with thunderbird (thunderbird is cachine connections) waiting forever and I noticed that dovecot is trying to acquire a lock but unsuccessful since the lock file is in place. Is it possible to use file locking other than dotlock on FreeBSD NFS mounted homedir? How do I achieve this? Thanks a lot. Tony Tsang.

[Dovecot] Server 1.0.1 migration: Maildir : UID inserted in the middle of mailbox
by damien chambe - EGS 29 Jun '07

29 Jun '07

Hello all, Since a migration from dovecot 1.rc16 to Dovecot 1.0.1 + new server, every day I have a lot of errors like this : Jun 21 17:42:34 dovecot1 deliver(damien.chambe(a)egs-gestion.fr): msgid=<467A9B3E.5070605(a)egs-gestion.fr>: saved mail to INBOX Jun 21 17:42:34 dovecot1 postfix/pipe[10242]: 92DD11FA8B: to=<damien.chambe(a)egs-gestion.fr>, relay=dovecot, delay=0, status=sent (egs-gestion.fr) Jun 21 17:42:34 dovecot1 postfix/qmgr[2724]: 92DD11FA8B: removed Jun 21 17:42:37 dovecot1 dovecot: IMAP(damien.chambe(a)egs-gestion.fr): Maildir /mnt/baie/hula/dovecot/maildir/damien.chambe sync: UID inserted in the middle of mailbox (374 > 1, file = 1182330228.P30307Q0M224874.dovecot1:2,ST) Jun 21 17:42:37 dovecot1 dovecot: IMAP(damien.chambe(a)egs-gestion.fr): Disconnected: Mailbox is in inconsistent state, please relogin.

No email are lost or duplicated, but it cause a huge traffic on our DSL lines, and user are complaining...

X86-32 I've kept the same configuration files for postfix, dovecot. We use dovecot deliver. Old postfix version was 2.1.1, now I have 2.2.9 During the migration, I've changed dovecot 1.rc16 to dovecot 1.0.0 When I saw this error, I upgraded to dovecot 1.0.1, but same problem (I use suse rpm packages ) I have 400 mailbox, all Maildir. The problem happens 50 times a day, so not on every mail received. I store mails on NFS, and index on local disk. There's only one dovecot server, so no multiple access. I've tried to remove all index files, and remove dovecot-uidlist, all is correctly re-created, but the problem remains. Could it be an NFS locking problem ? Since only mail are stored on maildir + NFS, and index on local disk, so I didn't set lock_method or nmap_disable Could it be related to this: see email from from Doug Concil : [Dovecot] NFS lock contention for dovecot-uidlist on may 17 , 2007 ? dovecot -n # 1.0.1: /etc/dovecot/dovecot.conf protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_user: dovecotlogin login_process_per_connection: no login_processes_count: 5 max_mail_processes: 2048 first_valid_uid: 120 first_valid_gid: 12 default_mail_env: maildir:/mnt/baie/hula/dovecot/maildir/%n:INDEX=/opt/dovecot/indexes/%n mail_location: maildir:/mnt/baie/hula/dovecot/maildir/%n:INDEX=/opt/dovecot/indexes/%n mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: verbose: yes passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: dovecot group: mail plugin: quota: maildir:storage=1500000:messages=40000 Thanks, -- Cordialement, Damien Chambe EGS 42 bld jules janin - BP 240 - 42006 Saint Etienne Cedex 1 Tel : 04 77 49 48 16 Fax : 04 77 49 48 45 Site institutionnel : http://www.groupe-laurent.com Site catalogue : http://ecat.groupe-laurent.com

[Dovecot] lda and mail_location
by Mark Edwards 28 Jun '07

28 Jun '07

I have the following set in the main level of my dovecot.conf file: mail_location = maildir:/var/mail/virtual/%u I decided to enable the lda protocol for local delivery from postfix, so I could use sieve plugins. The lda protocol seems to ignore settings in the rest of the dovecot.conf file, however, such as the above. Unless lda has a pre-existing maildir mailbox, it can't create one. How do I give lda defaults to follow, if the above statement doesn't do it? Here is the output of dovecot -n Thanks! ---- # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 imaps pop3s listen: 127.0.0.1 ssl_listen: [::] ssl_cert_file: /etc/ssl/private/mail.antsclimbtree.com.pem ssl_key_file: /etc/ssl/private/mail.antsclimbtree.com.pem login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login valid_chroot_dirs: /var/mail verbose_proctitle: yes first_valid_uid: 8 last_valid_uid: 8 first_valid_gid: 8 last_valid_gid: 8 mail_extra_groups: mail mail_location: maildir:/var/mail/virtual/%u maildir_copy_with_hardlinks: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh namespace: type: private separator: / inbox: yes auth default: mechanisms: plain login username_format: %Lu verbose: yes passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: mail group: mail
