[Dovecot] expire plugin with pgsql not working
by LÉVAI Dániel 09 Jan '09

09 Jan '09

Hi! I've configured dovecot, and created the db/table/trigger according to http://wiki.dovecot.org/Quota/Dict. I'm using dovecot-1.1.7 and pgsql. When moving a message inside the "monitored" directory, the expires table won't get updated because of an error: statement: INSERT INTO expires (expire_stamp, mailbox) VALUES ('1229993423', 'leva/spamassassin.SPAM') INSERT ERROR: null value in column "username" violates not-null constraint Wonder why doesn't dovecot pass the username too. What could be the problem? Daniel -- LEVAI Daniel PGP key ID = 0x4AC0A4B1 Key fingerprint = D037 03B9 C12D D338 4412 2D83 1373 917A 4AC0 A4B1

[Dovecot] Sudden, large numbers of "Timeout while waiting for lock for transaction log ..."
by Jack Stewart 09 Jan '09

09 Jan '09

Hi, Up until yesterday, our environment which consists an NFS maildir file store with multiple front end servers, was working fine. We've verified that the server clocks and machines clocks are in sync. Starting yesterday afternoon, We are getting ~850 log entries of the form 'Timeout while waiting for lock for transaction log files' or 'Our dotlock file was modified, assuming it wasn't overridden (kept it 180 sec) Based on packet capture, just one of these index files shows 28553 GETATTRs queries in in a one minute. At this happened at exactly the same time on all of our servers, it is pretty clear that the back-end system (or network) is a major factor although nobody will confess that they made any changes. It would be helpful, and very appreciated, to get more information about what this might be so that we can nudge the correct people to undo whatever it is that they didn't do.

[Dovecot] Enforcing TLS
by Ed Schouten 09 Jan '09

09 Jan '09

Hello all, I've happily been using Dovecot for a couple of years now, but only a couple of days ago I configured it to speak both TLS and SSL for both POP3 and IMAP. Ideally I want users to use TLS, but I've enabled SSL, because some mailers (at least Apple Mail on OS X Tiger) don't support TLS. Right now I'm in sort of a transitional phase, where I'm asking users to enable TLS in their email clients, if not enabled already. After a couple of weeks/months I want to disable any (non-local) connections that don't use TLS or SSL. I already asked on IRC whether this was possible, because I was unable to find this on the Wiki. It turns out there is a configuration switch called `disable_plaintext_auth', but looking at the description this only prevents people from using plain-text username/password authentication. It does not actually enforce TLS or SSL. My question: is there support to enforce TLS when people connect to non-SSL ports? If someone comes up with a solution, I'll add it to the SSL article on the Wiki. I'm using Dovecot 1.1.7, installed on a FreeBSD 6.4-STABLE system. Thanks! -- Ed Schouten <ed(a)80386.nl> WWW: http://80386.nl/

[Dovecot] Restoring individual messages from a backup into a Maildir setup?
by Thomas Harold 09 Jan '09

09 Jan '09

We have a user who deleted IMAP folders from his account, so I simply tried to restore the folder ".FolderName" from our backup. I checked that file/folder ownership was the same as the original, but the Dovecot IMAP server is throwing errors at the client. I've tried copying the individual message files from the "cur" folders in the backup directory, but Dovecot immediate goes into panic mode and throws errors at the IMAP client when I do that. Even if the file is owned by the currect UID. I've tried putting those files into "tmp" and "new" as well, with no luck. I looked at the following thread, but it didn't help. http://www.dovecot.org/list/dovecot/2007-August/024971.html The thread from Sep 2008 wasn't much help either: http://www.mail-archive.com/dovecot@dovecot.org/msg12846.html ... Eh, I figured this out before I even posted. Restoration is indeed that simple. The problem is that the files were not labeled with the proper SELinux security context after being restored. When the file was restored, it was assigned a context of "root:object_r:file_t", which is not a context that the Dovecot service has permissions to interact with. I had to re-label the files after restoring them with # chcon -R user_u:object_r:mail_spool_t foldername So the lesson here is to check /var/log/messages and look for sealert indicators when restoring files. ... Hopefully that helps some other people out when dealing with Red Hat / CentOS with SELinux set to enforcing mode.

[Dovecot] dovecot-auth Temporary But Frequent CPU Spike
by Joe Clark 08 Jan '09

08 Jan '09

Hi.. I am setting up a new server (2GHz CPU, Ubuntu 8.10) and am using dovecot for an IMAP server. I have installed dovecot 1.1.4 and Squirrelmail 1.4.15. sudo dovecot -n shows this: # 1.1.4: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_process_per_connection: no mail_privileged_group: mail auth default: passdb: driver: pam userdb: driver: passwd The problem I'm noticing is that if I do top -d 1 while clicking links in Squirrelmail (e.g., logging in, the Inbox link, opening a message), I see that a "dovecot-auth" process maximizes the CPU for about a second. While this is not a huge amount, it seems like with multiple users it could quickly bog down a server . Are there any recommendations or thoughts on what might cause the one-second CPU spike? -- or is that just normal operation? Thanks for your thoughts. - Joe Clark

[Dovecot] cannot delete emails in inbox
by JANE CUA 08 Jan '09

08 Jan '09

I am working on upgrading our current squirrelmail and replace uw-imap with dovecot. I have what looks like a successful installation. My current setup is: Centos 5.2 sendmail 8.13.8 dovecot 1.1.17 (imap) squirrelmail 1.4.17 I can send and receive email fine. However when I try to delete an email in my Inbox, it doesn't get deleted. It only sends a copy to the Trash folder. But the email is still in the Inbox. I can purge and delete the contents in my Trash and Sent folder, no problem. I am not sure if this is a Squirrelmail issue or a Dovecot issue. Please advice. Thank you -- Jane

[Dovecot] Dovecot-auth timeouts
by Javier Fox 08 Jan '09

08 Jan '09

Hello, I've unfortunately been unable to find anything relating to the problem I'm having specifically, in searching the list or google, and so I now plead to you to assistance. I'm running Dovecot as an LDA and SASL auth for Postfix on a Debian 4 box. Dovecot is version 1.0.rc15 (the official debian pkg version). The problem I'm running into is this. After some time of running (lately it's been as little as 5 minutes), I start to see the following errors in dovecot.log: deliver(user(a)domain.com): "Dec 23 14:38:47 "Error: User request from dovecot-auth timed out deliver(anotheruser(a)domain.com): "Dec 23 14:38:48 "Error: User request from dovecot-auth timed out Postfix responds to these by simply deferring the messages. Dovecot itself, however, begins to return 'Authentication failed' messages after significant lag time (sometimes greater than 30s): Connected to localhost. Escape character is '^]'. +OK Dovecot-POP user username +OK pass mypassword -ERR Authentication failed. Now, for authentication, Dovecot is using LDAP on the local server. The only additional information I can find pertaining to these errors is the following from slapd.log: slapd[22593]: connection_input: conn=6 deferring operation: pending operations These messages correspond 1-to-1 to the above 'deliver' errors, where 'conn' is always the same number. Restarting dovecot and ldap resolves the issue for a few minutes, but sure enough the errors start flowing again. I'm really at the end of my rope on this, as nothing I do seems to help. I have a good 500+ customers being effected by this as well, and they're all none too pleased by it. If this is something that will absolutely be resolved by upgrading from source, that is doable, but we'd prefer to stick with the official package version if possible.

[Dovecot] delivers mail to bad directory(prefix) using sieve filters
by Radim Roska 08 Jan '09

08 Jan '09

Hi, I've installed dovecot debian stable(from backports) version (1.0.15). Its great..i just have problem with sieve filters. I use only web tool for creating filters that works for me (avelsieve plugin for squirrelmail). it creates rules, where specified folder has prefix INBOX. Thats fine.. Since dovecot has configured prefix INBOX too. BUT mails are delivered to INBOX.INBOX.test_folder and thats ugly and not usable. I've figured out new version 1.2 should work, but i dont like idea to install not stable version to production server. Is there any patch or something for stable version? Thanks a lot! Radim

[Dovecot] Bug Report in Connection with Expire Plugin

08 Jan '09

Here are the first few simple patches from Apple, based on dovecot-1.1.7. The comments with "APPLE" in them helped us merge in your new releases; feel free to remove them. Please let me know if you want subsequent patches in a different format, or if you have any questions. Patch #1. Some versions of Mac OS X have buggy CMSG_* macros. Patch #2. Don't set "<username>=1" in the environment. Patch #3. Some versions of Mac OS X return near-duplicate kevents. Patch #4. Null renames are actually pretty slow on HFS (Apple's file system), so avoid them. Patch #5. Required by Apple's lawyers.

[Dovecot] Apple patches 6-8
by Mike Abbott 08 Jan '09

08 Jan '09

Here are a few more patches. Still keeping it easy for now. Again the basis for these patches is dovecot-1.1.7. Patch #6. Solve a cross-compilation endianness issue. Currently, Dovecot assumes that the endianness of the build system is the same as the endianness of the runtime system. This is not necessarily true. We ran into this while compiling for i386 on a ppc machine. The patch switches to using gcc's __BIG_ENDIAN__ macro; see the comment in the patch to configure.in. It also removes the related and unused MAIL_INDEX_COMPAT_FLAGS parameter. This patch may be applicable to other build environments with a little tweaking. Patch #7. Replace all occurrences of "hash_create" and "hash_destroy" with "hash_table_create" and "hash_table_destroy" respectively. The symbols hash_create and hash_destroy conflict with symbols defined in <strhash.h> and libc. This showed up when loading dovecot's quota plugin (one of our future patches will add a hash table to it; stay tuned). The wrong hash_create was called which caused a crash at the first hash_insert. Apparently this is only a problem in loaded dynamic libraries and not linked-in ones. Patch #8. Back off after auth failures to deter abusers. Stalls 5 seconds per failed attempt. PS -- Please forgive me if I make a mistake at some point while splitting these patches out from our source tree. They're all mingled together on my end and it's sometimes tricky to extract just the right changes for each patch. If anything seems fishy just let me know and I'll take another look. Thanks.

[Dovecot] ManageSieve woes
by Rodti MacLeary 08 Jan '09

08 Jan '09

Hi everyone, New to the list, and fairly confident that this issue is purely down to my own idiocy, so please go easy on me! I've been running Dovecot 1.0.13 on Debian (via Aptitude package) for some time, and have been delighted with it. For a while I've toyed with the idea of using ManageSieve as there's a nice plugin for Roundcube, so I'm trying to follow the how-to at http://wiki.dovecot.org/ManageSieve. First of all I've downloaded the Dovecot 1.1.7 source and compiled it myself. I've patched it using the appropriate ManageSieve 1.1.7 diff file referenced in the how-to, and it all appears to be running fine. The next step is to compile the ManageSieve 0.10.4 source itself. I've extracted the tarball and attempted ./configure, but it's failing with the following errors: ./configure: line 19826: cd: ../dovecot: No such file or directory ./configure: line 19829: cd: ../dovecot-sieve-1.1: No such file or directory dovecot-config not found from /home/user/dovecot-1.1-managesieve-0.10.4, use --with-dovecot=PATH to give path to compiled Dovecot sources or to a directory with the installed dovecot-config file. configure: error: dovecot-config not found I'm not entirely sure what I'm supposed to be pointing --with-dovecot to here. I've tried the Dovecot 1.1.7 source, and /etc/dovecot. Any help greatly appreciated! Rodti

[Dovecot] Checking for strtoumax and strtoimax
by J Springer 08 Jan '09

08 Jan '09

Tru64 5.1b PK6 : dovecot 1.1.7 : cc Configuration checks for strtoumax and strtoimax are positive but both are unresolved during compilation. strtoq and strtouq checks are negative. I can modify compat.c to use "unsigned long ret = 0;" in place of strtoumax (does this break anything?) and/but I would like to know how to handle strtoimax. Thanks in advance.

[Dovecot] allow_nets overridden by cache
by Guy 08 Jan '09

08 Jan '09

Hi, I've just started trying allow_nets on one of my servers. I have auth_debug and auth_verbose both enabled and the output is as follows: Oct 28 13:05:48 mink dovecot: auth-worker(default): auth(user(a)domain.net,x.x.x.x): allow_nets: Matching for network 127.0.0.1/8 Oct 28 13:05:48 mink dovecot: auth-worker(default): auth(user(a)domain.net,x.x.x.x): allow_nets: Matching for network 10.0.7.176/28 Oct 28 13:05:48 mink dovecot: auth-worker(default): passdb(user(a)domain.net,x.x.x.x): allow_nets check failed: IP not in allowed networks Oct 28 13:05:50 mink dovecot: auth(default): client out: FAIL 1265 user=username(a)aluminati.net Oct 28 13:05:50 mink dovecot: auth(default): cache(user(a)domain.net,x.x.x.x): hit: <hidden> user=user(a)domain.net Oct 28 13:05:50 mink dovecot: auth(default): client out: OK 1266 user=user(a)domain.net auth_cache_ttl is set to 300. If I set it to 1 then the allow_nets successfully rejects. Once I set it back up to 300 the cache overrides the result from the allow_nets check and let's the account log in even though the allow_nets check fails. I've tried waiting for longer than the 300 seconds and then logged in again, but I still get the same result as above. Is there a gotcha that I'm unaware of or have I done something stupid (which seems the most likely :P)? Thanks Guy -- Don't just do something...sit there!

[Dovecot] Setting IMAP keywords/flags on delivery
by Matt Doran 08 Jan '09

08 Jan '09

Hi there, We've been long time users of Dovecot, and have found it a great IMAP server. I don't think we've had any serious problems in the 3-4 years of use. So great work. :) We have a IMAP inbox that is accessed by a number of different users from Thunderbird. We have a rule in Thunderbird to flag new emails as "TO DO", so someone can unflag the email once it has been actioned. This process works fairly well for a simple workflow, but problems arise when someone connects to the inbox with a Thunderbird instance that doesn't have the "TO DO" rule configured. The email will not be flagged properly. :( I'd like to be able to set this flag/keyword when the mail is delivered to the inbox, on the server side. That way the flag will be set no matter which client accesses the Inbox first. We currently use mail drop for our server-side mail filtering .... and would like to do a similar thing with this flagging process. We're using Dovecot 1.0.15 on Debian Testing, and use Maildir storage and maildrop as our delivery agent. I've read about how the keywords and Thunderbird labels work in the wiki article here (http://wiki.dovecot.org/MailboxFormat/Maildir) So I could probably write some sort of script to query the "dovecot-keywords" file, and rename the Maildir file to set the appropriate flag. But this sounds a like a bit of a hack, and maybe a little dangerous. Does anyone have any recommendations as to how I could achieve something like this? I'm keen to hear any ideas, whether it's through scripting, or some sort of scriptable/command-line IMAP client. Ideally, we'd have a way to set the flag at the time when the mail is delivered.... or when the first client retrieves any new mail?

[Dovecot] Default dirs in ./configure?
by Peter Lindgren 08 Jan '09

08 Jan '09

Hi! I try to build a new 1.1.7 installation. Since I'm not a large sysadmin, just my own private mail server admin, I just wonder why the sysconf and state dirs defaults to $prefix? Maybe I'm old-school, but isn't /etc and /var, respectively, a better default than /usr/local? Should require two new variables in the configure script, though. (and yes, I know I set them with --sysconfdir=/etc --localstatedir=/var --sharedstatestatedir=/var ) /Peter -- Peter Lindgren http://www.norrskenkonsult.com

Re: [Dovecot] login fails when username has apostrophe

[Dovecot] Problem with opening ports in alpha5 ?
by Bruce A. Mallett 07 Jan '09

07 Jan '09

If I leave the "listen" value as the default in /etc/dovecot.conf I'll get a message similar to the following on each port that it tries to open during startup: # dovecot -F Fatal: listen(::, 143) failed: Address already in use If I set either: listen = * or listen = [::] then it will start up fine. Perhaps it is as though the code tries to open the port twice for both ip4 and ip6? - Bruce

[Dovecot] Apple patches 11-14
by Mike Abbott 07 Jan '09

07 Jan '09

These are the last patches for now, and they're small. The base for each of them is dovecot-1.1.7 + Apple patches 9 and 10, again not because of a logical dependency but just because these patches change parts of the earlier patches. Patch #11 adds a few dtrace providers to key points in the code. We are still validating the correct placement and usefulness of these. One cool thing about dtrace is that when not in use the hooks literally are just a couple of no-op instructions. Patch #12 increases many listen queue sizes to handle high loads better. The new values are not necessarily the best possible values but they do allow more throughput. Patch #13 makes dovecot adapt to dynamic host identity changes upon config reload. Patch #14 covers three miscellaneous changes, to support more file descriptors and an "unlimited" number of mail processes, and a different default mail user. That's all our patches for now!

[Dovecot] writing a dovecot plugin / segfault
by Stefan Jurisch 07 Jan '09

07 Jan '09

Hi together, I am new to this list and new to dovecot itself. I have to write a plugin that implements some ACL-voodoo to be used instead of the standard ACL stuff of dovecot (it shall allow just application-driven folder-sharing - no more, no less). Though I started programming with C, my last experiences are some days old, but now I have written the function sekeletons and the registration function with the 'register-command"-calls etc. The makefile-stuff I copied from the imap-quota-plugin and modified it, so all appearances of "lib11_imap_quota_plugin..." and similar are now found as "lib11_folderacl_plugin..." and so on. In short words: I think I have done all nessessary mods to the source (I tried it some days ago with a slightly older version of dovecot, and until I did some unknown thing, it worked quite well...) to make the whole thing work. One example function is (just testing at the moment): /* MYRIGHTS <folder>: retreive the rights of the current folder */ static bool cmd_myrights(struct client_command_context *cmd) { struct mail_storage *storage; struct mailbox *folder; const char *folder_name; string_t *response; /* read argument: <folder> */ if (!client_read_string_args(cmd, 1, &folder_name)) return FALSE; /* work done from here... */ /* for the moment, do a dummy response */ str_append(response, "* MYRIGHTS "); str_append(response, folder_name); str_append(response, " lrswipcda"); client_send_line(cmd->client, str_c(response)); client_send_tagline(cmd, "OK Completed."); return TRUE; } But when testing via "telnet localhost 143" and doing a "20 myrights INBOX" the imap thread just crashes and does not give any answer. in /var/log/messages I only find something like the following entry: Jan 5 13:40:12 kungfu kernel: imap[8991]: segfault at 4 ip 080d5c67 sp bf82b040 error 4 in imap[8048000+b8000] Maybe somebody can tell me, what this is? If needed, I also post the complete code itself somewhere. Thanks in advance.

[Dovecot] mbox "Next message unexpectedly lost" bug fixed
by Timo Sirainen 06 Jan '09

06 Jan '09

Good news, everyone! The most annoying bug in v1.1 series should finally be fixed by these patches: http://hg.dovecot.org/dovecot-1.1/rev/f28348c5201e http://hg.dovecot.org/dovecot-1.1/rev/74c47fcfb420 http://hg.dovecot.org/dovecot-1.1/rev/a28520d26b5a http://hg.dovecot.org/dovecot-1.1/rev/539f8d983285 http://hg.dovecot.org/dovecot-1.1/rev/9b7af230f9f0 They also make sure that mbox is never read while it's not locked. I think that could have happened in some situations with v1.1. Hopefully mbox handling will now finally be as stable in v1.1 as it was in v1.0. I'll make a new v1.1 release after seeing what bug fixes are coming from Apple, so probably next week.

[Dovecot] New SSL certificate problem
by Stewart Dean 05 Jan '09

05 Jan '09

Our DC has been using a Verisign certificate. Over the past year, we've been using a Digicert Wildcard Plus certificate for almost all of our machines, and I wanted to switched over our DC mailserver. I used the following command to generate the CSR and key: openssl req -new -newkey rsa:1024 -nodes -out star_bard_edu.csr -keyout star_bard_edu.key -subj "/C=US/ST=NY/L=ourtown/O=Bard College IT/OU=Bard College /CN=*.bard.edu" The resultant CSR verified and I submitted it to digicert and got back our cert, plus their intermediate and Trusted root certs. I killed the root instance of dovecot and waited for all the children to die I put together the intermediate cert (first) and our cert (second) into /usr/ssl/certs/dovecot.pem I put the key star_bard_edu.key in /var/ssl/private/dovecot.pem I restarted dovecot, but the imap login instances didn't appear, so I shifted back to the original combined cert file and key, restarted dovecot and it came up OK I check the syslog and saw these error messages: Jan 5 10:19:49 mercury mail:err|error dovecot: imap-login: Can't load private k ey file /var/ssl/private/dovecot.pem: error:0B080074:x509 certificate routines:X 509_check_private_key:key values mismatch Jan 5 10:19:49 mercury mail:err|error last message repeated 8 times Jan 5 10:19:49 mercury mail:err|error dovecot: child 4051108 (login) returned e rror 89 Jan 5 10:19:49 mercury mail:err|error dovecot: child 4231382 (login) returned e rror 89 I checked my key and it has the same time stamp as my CSR, so I didn't somehow get the wrong key. Both the old and new key are 600; if the old one works based on perms, the new one should too. Would some kind soul tell me what I'm missing? Or is there a problem using wild card certificate with DC? Is there an openssl command to verify the key. Or is it that the key is unencrypted? -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors.

[Dovecot] Permission to distribute Dovecot run file
by Rick Widmer 05 Jan '09

05 Jan '09

I am working on updating the Shupp toaster, http://shupp.org/toaster/ a set of files and instructions for installing qmail, vpopmail, qmailadmin and squirrelmail. Two of my most important goals are switching the imap program from courier to Dovecot, and closer integration with OpenSuSE. (Which I run my mail servers on.) To follow the style of the toaster I need a place where I can obtain the init.d script from http://wiki.dovecot.org/DovecotInit I would prefer to have permission to host the file myself so I don't have to worry about creating patches if there is ever a need for my run file to be different from yours. If that is not acceptable, would you please either provide a URL where I can download just the run file, or include it in the distribution. Thanks, Rick

[Dovecot] convert non-standard mbox to maildir
by Maarten Bezemer 04 Jan '09

04 Jan '09

Hi, Let me start with wishing you all the best for this new year, and I hope we'll see a lot of new features and not so much new bugs ;-) I'm trying to convert a number of PSTs to maildir. Just plain drag&drop in Outlook doesn't work (gives a very cryptic error message in a certain folder, but that folder is perfectly all right), and using the import option also barfs when it's not even half-way through the PST. So, I took aid4mail and it converted the PST to mbox wihtout any problem. But now, I have a directory structure, filled with mbox mailboxes. Like: INBOX INBOX/mailbox INBOX/subfolder INBOX/subfolder/mailbox INBOX/subfolder/subsubfolder INBOX/subfolder/subsubfolder/mailbox INBOX/subfolder2 INBOX/subfolder2/mailbox etc. This differs from normal mbox setup, but given the fact that there are both folders AND messages below inbox, this is indeed the only useful way to do it. But now I cannot convert this to maildir using either dovecot or mb2md, since it's not the usual mbox setup. Any suggestions would be greatly appreciated! Thanks in advance, Maarten

[Dovecot] deliver looking into root directory for sieve configuration ?

All virtual mailboxes are in /home/vmail/DOMAIN/USER/.maildir (owned by postfix:postfix; dspam has been put in the postfix group) I uploaded the following config files in http://hiltg.pastebin.com/ : - main.cf - master.cf - dovecot.conf - dspam.conf (mails are supposed to be delivered to the mailbox by dovecot, which is called by dspam) Any idea please ? Thanks and happy new year to you all, -- Guillaume Hilt

[Dovecot] Unkillable imap process?
by Johan Persson 03 Jan '09

03 Jan '09

Hi, Not sure if this is relevant but having been running dovecot 1.1.4 for a long time (without any problem) I recently upgraded to 1.1.7 when I switched to SuSE 11.1 This is just running on my home server and it's a fairly standard fetchmail-procmail-dovecot setup. However I recently had an incident which I cannot quite explain. I suspect it could be a possible disk problem but I did run a SMART check and the disks and HW seems ok. The mail store is mounted on a separate partition using ext3 fs What happened was that I noticed that the load on my server went through the roof and that the imap process was hogging 100% of the CPU and it had been running so for over an hour. Before this happened I had just setup a new laptop with Thunderbird as the mail client and had just done a off-line sync of my whole mail store (~1.5GB). So for a short time the dovecot server would have been under maximum load. I tried to recover by gracefully shutting down dovecot and when that didn't stop the imap process I first tried to be nice by sending it the TERM signal and when that didn't do it, the KILL signal. However, I was not able to stop the imap process. I then decided to recycle the server and initiated a shutdown. However, not even that was able to complete (since the shutdown process seemed to be hanging on not being able to stop the imap process). In the end I was (for the first time in over 6 years) forced to use the hard reset button on the server. I do realize that this is almost impossible to diagnose, but does anyone now in general what could possible cause the imap process to so completely be locked up that it is impossible to even shut it down? The dovecot -n output is 1.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27.7-9-pae i686 openSUSE 11.1 (i586) ext3 log_path: /var/log/dovecot.err info_log_path: /var/log/dovecot.info login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 2 login_max_processes_count: 2 login_max_connections: 5 max_mail_processes: 32 mail_max_userip_connections: 8 mail_location: maildir:/srv/mail/%u mailbox_idle_check_interval: 15 fsync_disable: yes auth default: passdb: driver: pam userdb: driver: passwd Cheers Johan

[Dovecot] NFS, IDLE, and index locking
by Jack Stewart 31 Dec '08

31 Dec '08

Hi, I'll try to keep short. My primary question is what, in people's experience, are the best configuration settings for to avoid potential NFS cache locking issues in an interesting heterogeneous environment? We appear to have a workaround for some locking issues we have seen, which is turning off IDLE. Upgrading our version of dovecot from 1.1.4 is likely to address some core issues, but I want to get the system setup in tune first. There are some things in our setup that seem dumb, and I would like to make sure they are dumb. As far as our environment goes, it isn't unusual for our users to connect with multiple different clients from multiple locations. Some of these clients behave well, and some not so well. In addition we have multiple distributed servers with multiple instances. Generally the connection from one of their clients/desktops goes to the same server but their different desktops may connect to different servers. If anyone has a similar enough environment, do you find it better to have the hard link setting off or is it better for you to turn it on? The attribute cache is the default (60 seconds) which works well enough in a polling setting but may be a problem with IDLE (30 second check). Do you find it better to bump up the IDLE check interval or drop the attribute cache? Our cache and maildir are on separate NFS volumes so we can change one without changing the other. Our tcp timeout setting is too long (it is the default). Do you find 180-300 seconds more reasonable? ---Jack To give some context, we have a handful of users with intermittent caching locking where the dovecot.index.cache file would simply not update. One of our internal people managed to get this problem when he was using pine (non-IDLE) with gnubiff (IDLE) from the same desktop. We haven't had any alarms since taking the brute force approach of turning off IDLE. Unfortunately other projects are inhibiting my capacity for additional debugging at this time. Also, it isn't clear to me that we will learn anything useful since the servers do not appear to be tuned and they are only running dovecot 1.1.4. Just for reference, below is our dovecot configutation. disable_plaintext_auth = yes base_dir = /var/run/dovecot/imap-server-its/ protocols = imap imaps syslog_facility = local4 shutdown_clients = yes ssl_cert_file = xxx.pem ssl_key_file = yyy.key ssl_ca_file = zzz.pem mail_location = maildir:/var/spool/maildir/%1Ln/%Ln:INDEX=/var/spool/dovecot/indexes/%1Ln/%Ln login_greeting_capability = no verbose_proctitle = yes mail_debug = yes imap_capability = "IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1" # MAILDIR Performance settings maildir_copy_with_hardlinks = yes maildir_copy_preserve_filename = no # Handling web logins & imap traffic login_processes_count = 16 login_max_processes_count = 2048 max_mail_processes = 4096 mail_max_userip_connections = 2000 # NFS settings mmap_disable = yes fsync_disable = no mail_nfs_index = yes mail_nfs_storage = yes dotlock_use_excl = yes lock_method =fcntl protocol imap { listen = *:10143 ssl_listen = *:10993 imap_client_workarounds = delay-newmail outlook-idle netscape-eoh } ## Authentication processes namespace private { separator = . prefix = Mail. inbox = yes } auth_verbose = yes auth default { mechanisms = plain login passdb ldap { args = /etc/dovecot.conf-ldap } userdb static { args = uid=vmail gid=mail home=/var/spool/maildir/%1Ln/%Ln } socket listen { master { path = /var/run/dovecot/imap-server-its/auth-master user = vmail group = mail } user = root }

[Dovecot] Bug in Dovecot 1.0.5 - CRYPT-MD5 not working
by Jim Salter 30 Dec '08

30 Dec '08

Problem: Using MySQL storage for the user and password db with MD5-CRYPT hashes, Dovecot fails to successfully authenticate when the MD5-CRYPT or MD5 settings are specified as default_pass_scheme in dovecot-mysql.conf. Dovecot /does/ successfully authenticate against MD5-CRYPT hashes when default_pass_scheme is set to CRYPT, which according to the docs should be DES encryption. (I do not know whether or not CRYPT actually works with DES hashes.) I am positive that I am using MD5-CRYPT hashes, as I have dropped in hashes from a Qmail/Vpopmail vpasswd file and they work with the CRYPT setting in Dovecot, as do hashes generated using htpasswd -nmb. Test system: Ubuntu Server 7.10, amd64 Dovecot 1.0.5 (from Ubuntu repositories) Postfix 2.4.5 (from Ubuntu repositories) Demonstration: # cat /etc/dovecot/dovecot-mysql.conf driver = mysql connect = dbname=redacted user=redacted host=127.0.0.1 password=redacted default_pass_scheme = MD5-CRYPT password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT maildir, 105 AS uid, 114 AS gid FROM mailbox WHERE username = '%u' # htpasswd -nmb user password user:$apr1$bZQl//..$2IPoOibTBaqpG7pPFigOy/ # mysql -u postfix -p mysql> use redacted; Database changed mysql> update userdb set password='$apr1$bZQl//..$2IPoOibTBaqpG7pPFigOy/' where username='user'; Query OK, 1 rows affected (0.00 sec) mysql>quit Bye # telnet localhost 143 Trying 127.0.0.1...

I'm really racking my brain trying to figure this one out here. I am running a pop3 server for remote offices on CentOS 5.2.

[Dovecot] automounting home dirs
by Roger Hale 29 Dec '08

29 Dec '08

Hi, I'm running dovecot-1.0.10 on a Solaris 10 server with home dirs automounted over NFS. I have set the mail_location configuration option so that nothing should be written to a user's home dir over NFS but, as far as I can tell, dovecot still by default tries to chdir to a user's home dir when reading mail, although this is not required. This creates additional unnecessary load on a heavily-loaded fileserver and generally slows everything down and creates an unnecessary dependency. Is there a way to prevent dovecot from causing the home dirs to be mounted? I found this thread: http://markmail.org/message/umywuppl3vvzfe4p#query:dovecot%20mount%20home%2… which discusses the same problem, but it's quite old and there doesn't seem to be a definitive answer other than hacking the passwd file or the code. Is there a more elegant solution? TIA. _________________________________________________________________ Get a bird’s eye view of the world with Multimap http://clk.atdmt.com/GBL/go/115454059/direct/01/

Hi dovecot list, I'm looking for a possibility to log a moved (or a deleted mail). For example, I have a mailbox, and I read it in IMAP. I have a mail in INBOX. I want to move it to Folder. I want to have this action logged in my dovecot log file (or an other file). Is it possible? I read this: http://wiki.dovecot.org/Logging and I don't find any informations about it. I try to set "mail_debug=yes", but it does not log what I want. Thanks. Best regards (and happy Xmas). -- -Nicolas.

Hi dovecot@. I use the last dovecot (1.1.7) with sieve-plugin. All works perfectly. However, I would like to use a "copy" function. All mail sent by "toto(a)domain.tld" have to be copied in a folder (copy, and not move). So, I don't want to use a fileinto rule. I see in http://wiki.dovecot.org/LDA/Sieve there is a copy function (1.1 only). A rule like: if header :contains "From" "toto(a)domain.tld" { copy "test"; stop; } does not work. I have nothing into my deliver or dovecot log. However, if I replace copy by fileinto, it works. But I want to copy the email, not move it. I don't find any examples in the Internet or the wiki. Could you help me? Thanks! -- -Nicolas.

Hello, I was wondering is I could use MySQL as storage only..? Meaning that no user information, other than the obvious email address associated with an specific email so that each email can be showed to the right user, will be stored in a MySQL database instead of /home/vmail/DOMAIN/<user> Would I get any advantages.? Would it be better, faster? Thanks

23 Dec '08

Hello, I set up Dovecot so that I now have about 20 domains on my mailserver. So far everything works fine. Now I have the need to set up shared maildirs, but they shall only be shared for the users of just one domain. What do I have to do? Thanks in advance for any hint! Volker

[Dovecot] Is there a straight forward way to associate login with imap process
by Jack Stewart 23 Dec '08

23 Dec '08

Hi, Is there a way to associate a user's the login (imap-login) process with the user's 'imap [' process? We are trying to lock down an issue to make sure we full understand it. /proc and shared memory tools weren't particular useful. Just for context, we are having an intermittent locking index cache locking issue that appears to impact only a subset of our users. The index files are on NFS. It may be fixed by a dovecot patch (we are at 1.1.3), adjusting our tcp_timeout on the servers, upgrading out circa 2000 load balancer, the type and configuration of the multiple simultaneous persistent clients that user is using, etc. lslk, alert logs, strace, testing the most recent 1.1.X version, and file mtime is giving us some information but we want to make everything is covered. Many thanks in advance. ---Jack -- Jack Stewart California Institute of Technology jstewart(a)caltech.edu / www.imss.caltech.edu

[Dovecot] POP3 Immediate Connection Termination
by Kat Wisnosky 22 Dec '08

22 Dec '08

Hey everyone... Thanks in advance for any help. I seem to have the opposite problem that a lot of people have - I've been running Dovecot v. 1.0.10 quite successfully for IMAP for several months. However, one of our executives has her heart set on being able to get her mail via POP3. It looks to me like I have both configured, but when trying to log in via a POP3 or POP3s connection either via a client or through telnet, the connection is created than immediately terminated.

[Dovecot] Move mail in Maildir without IMAP
by RW 21 Dec '08

21 Dec '08

I set-up some spam/ham learning folders where a crontab entry learns the mail and them moves it do a different Maildir folder. Unfortunately, since it has a different dovecot-keywords file, any imap flags get changed to unknown-0, unknown-1 etc. I tried the following, but it didn't work mv "${src_ham}"/cur/* "$dest_ham"/new/ cp "${src_ham}"/dovecot-keywords "${dest_ham}" Is there a simple way to do this correctly without going through IMAP? And are there any more serious consequences of moving mail like this, with dovecot imap running on top.

Hello, I intend to set up a mail server for a few domains with Dovecot/Postfix/MySQL/DSPAM and antispam plugin. The better solution to manage users would be to set up a ldap server. So, do anyone have ever set up this kind of server with dovecot ? Any advice that would help me ? Thanks, -- Guillaume Hilt

[Dovecot] More info from mail_log plugin
by Bardur Haskor 19 Dec '08

19 Dec '08

HiWe need to track exactly when our users read messages. Unfortunately, I haven't been able to figure out how we can achieve this with Dovecot. Then I saw the mail_log plugin.Is it possible to extend the plugin to also log system flag changes? This would be great, because then we could see in the log files when the Seen flag has been set. Changes in user defined flags would also be interesting to track.I know this would create a lot of log entries, but for us this wouldn't be a problem. Maybe the plugin would default to not tracking flag changes, but could be configured to do so.RegardsBardur Ha Skor _________________________________________________________________ Connect to the next generation of MSN Messenger http://imagine-msn.com/messenger/launch80/default.aspx?locale=en-us&source=…

[Dovecot] "nopassword" extra field useless with LDAP passdb
by Zohan 19 Dec '08

19 Dec '08

Hi, We are trying to implement a highly secure mail server with user authentication restricted to SSL certificates only (not using passwords at all). Still, user information is stored in a LDAP directory. In this configuration LDAP is used to check whether the user is registered (and probably supply quota and other info), and actual authentication is done by SSL layer. According to wiki, a "nopassword" extra field should be supplied, together with empty password. But there is no way to return an empty password from LDAP, as LDAP simply does not allow "empty attributes"; if an attribute is present, it is not empty. Supplying empty password as a static field (like this: pass_attrs = uid=user,=password=,nopassword) works an odd way, allowing empty password only, not "any password", and most MUAs (including our target Thunderbird) do not allow empty passwords. Log excerpt follows ("1" was entered as a password during POP3 session; static empty password was configured as above): ==================== Dec 9 02:11:15 localhost dovecot: auth(default): ldap(user1,127.0.0.1): pass search: base=ou=People,dc=example,dc=com scope=subtree filter=(&(objectClass=inetOrgPerson)(uid=user1)) fields=uid,nopassword Dec 9 02:11:15 localhost dovecot: auth(default): ldap(user1,127.0.0.1): result: uid(user)=user1 Dec 9 02:11:15 localhost dovecot: auth(default): ldap(user1,127.0.0.1): Password mismatch Dec 9 02:11:15 localhost dovecot: auth(default): ldap(user1,127.0.0.1): PLAIN(1) != '' Dec 9 02:11:17 localhost dovecot: auth(default): client out: FAIL 1 user=user1 Dec 9 02:11:19 localhost dovecot: pop3-login: Aborted login (auth failed, 1 attempts): user=<user1>, method=PLAIN, rip=127 .0.0.1, lip=127.0.0.1, secured ==================== That's why we now have to maintain a separate passwd-like file with the following contents: user1:::::::nopassword user2:::::::nopassword ... and so on (updating it each time manually as users are added/removed), and use it as passdb. Only this allows true "any password" policy. In fact, the problem seems to be a little bit deeper. In our setup user/password challenge is not needed at all. This is exactly what RFC 4959, "IMAP Extension for Simple Authentication and Security Layer (SASL) Initial Client Response", is about (http://tools.ietf.org/html/rfc4959 , see SASL EXTERNAL example). Are there any plans to implement SASL EXTERNAL mechanism in Dovecot? Thank you! Zohan

[Dovecot] OT: Looking for a robust IMAP client
by Stewart Dean 18 Dec '08

18 Dec '08

This weekend we had a runaway email endless loop. When it was killed after 18 hours, my inbox had 135,000 messages in it...there were two messages that were being endlessly sent and bounced and I'm on the postmaster alias. Thunderbird was able to do a mass select of one of the two messages, and deleted 65,000, but after that it locked up. I ended up firing up Pine to do the final 65,000...whereas TBird had had mulitple imap sessions (and failed), Pine only had one and did the job. And even after I had done the mass delete of the other 65,000 and the inbox was down to 2000 messages, TBird was still hiding under the covers and telling me there were still 135,000 messages. In the end, I had to kill the TBird profile for that account and recreate it. Is there a simple robust IMAP client to replace Pine (which I *think* is no longer supported)? GUI or TTY session? I'm wondering if there is something we can tell users to use when Things Are Dire. GUI would be better since it removes one of the few remaining reasons for a logon server -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] [PATCH] drop root privileges on solaris, request for testing
by Andrey Panin 18 Dec '08

18 Dec '08

Hello all, this patch allows master process to drop more root priveleges under Solaris. My limited testing shows that code works, but I'm not sure that defined privilege set is permissive enough for dovecot. Unfortunately I have no root access to our Solaris servers to really test it. So if someone is ready to test this patch please do it :) Best regards.

[Dovecot] Dovecot imap processes pinning CPU
by David Rosenstrauch 18 Dec '08

18 Dec '08

In recent days, dovecot's "imap" processes keep getting stuck. Each time I check my server (running dovecot 1.1.7) there's a bunch of "imap" processes (sometimes 2 of them, sometimes 4, sometimes 6) that are using all of the box's CPU. And worse, there's no way to kill the processes either (neither kill -15 or kill -9 works), which means that I wind up having to reboot the box every time this happens. REALLY irritating. I don't normally even *see* the imap processes in htop, as I think they're pretty short lived. And I'm not sure what they're looping trying to do. My debugging skills on Linux are a bit weak, and so I don't know how to look at the process and see what it's doing. Also, not sure what's changed on my system to cause this, as this is definitely a recent problem. Maybe the upgrade to Thunderbird 2.0.0.18 (since I usually use T'Bird to access my email). I don't seem to run into this problem when I use Squirrelmail. Anyone have any idea what the problem might be? Or, if not, then suggestions on how I might be able to debug the situation myself? TIA, DR

[Dovecot] SSL Certificate Authentication
by Anthony Davies 18 Dec '08

18 Dec '08

Hi Guys, I am using the SSL Client Certificate authentication method for my Dovecot instance, however rather then just requiring the client certificate it also prompts me for my user password. My certificate was securely generated on a smart card and is passphrase protected so I would like to stop having to enter my certificate passphrase and my user password to collect my mail. Where abouts in the config file can I resolve this issue? Cheers, Tony Davies

[Dovecot] v1.1.6 released
by Timo Sirainen 17 Dec '08

17 Dec '08

http://dovecot.org/releases/1.1/dovecot-1.1.6.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.6.tar.gz.sig The invalid message address parsing bug is pretty important since it allows a remote user to send broken mail headers and prevent the recipient from accessing the mailbox afterwards, because the process will always just crash trying to parse the header. This is assuming that the IMAP client uses FETCH ENVELOPE command, not all do. Note that it doesn't affect versions older than v1.1.4. + dovecot -n and -a now prints some system information at the top. + More error/debug message logging improvements. - pop3-login: Fixed assert-crash if a client sent USER+PASS+USER+PASS commands in the same IP packet. - Parsing an invalid message address like "From: (" caused an assert-crash in v1.1.4 and v1.1.5. - Folding whitespace wasn't handled correctly inside quoted-strings, causing some messages to be parsed incorrectly. - mbox: Fixed saving messages that begin with a valid From_-line.

http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha5.tar.gz http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha5.tar.gz.sig It's been a while since alpha4 so I thought I'd release a new one while waiting for Apple's patches.. - mbox fixes. - Lots of Solr fixes - Virtual mailboxes + Solr works now nicely instead of duplicating the indexed data. - Added alias_for setting for namespaces, also useful to avoid duplication of Solr indexed data if you have multiple namespaces that point to the same location (e.g. both "" prefix and "INBOX." prefix compatibility). - %variables now support long %{variable_names}: http://wiki.dovecot.org/Variables. I was planning on using these to redesign LDAP configuration (e.g. home=/var/mail/%{ldap:homeDirectory}) - imap/pop3 proxy: Support master user logins. - Improved some error messages

[Dovecot] Syncing several emails accounts with offlineimap and dovecot
by Joe Bloggs 16 Dec '08

16 Dec '08

Hi, I have just installed dovecot and offlineimap on my laptop for syncing with my gmail, and reading in gnus, as outlined in this article: http://sachachua.com/wp/2008/05/08/geek-how-to-use-offlineimap-and-the-dove… I am using Debian Etch, and I am the only user. The only change I made to the default dovecot.conf file was to set: mail_location = maildir:~/MailDir I read that gnus doesn't handle Maildir very well, so I need to connect directly to dovecot, and this is what I have specified in my offlinemap conf file: [Repository Local] type = IMAP remotehost = localhost port = 143 remoteuser = me remotepass = secret I want to sync my other online email accounts aswell. Can anyone tell me how to do this? Thanks.

[Dovecot] dovecot >1.1.3 + antispam plugin issues
by Marcin Rzepecki 16 Dec '08

16 Dec '08

Hello, i have following problems using dovecot-antispam plugin (Dovecot >1.1.3, FreeBSD 8.0-Current, dovecot-antispam 1.0/1.1) dovecot-antispam compiled using dspam-exec/mailtrain, with/wo debugging (i've tried all possibilities) When i try to move message to SPAM folder (using dspam-exec backend) i'm getting IMAP error: antispam signature not found and in dovecot logs: Nov 23 23:44:24 freebsd dovecot: IMAP(mr): Next message unexpectedly lost from 2708619 Using mail backend gives this error too(only IMAP error changes: failed to read mail beggining). Commenting out following code in mbox_read_from_line function (in src/lib-storage/index/mbox/istream-raw-mbox.c) helped and plugin was working correctly, but only with Dovecot <=1.1.3. if (stream->istream.v_offset - rstream->hdr_offset + new_pos > rstream->mail_size) { /* istream_raw_mbox_set_next_offset() used invalid cached next_offset? */ i_error("Next message unexpectedly lost from %"PRIuUOFF_T, rstream->hdr_offset + rstream->mail_size); rstream->eof = TRUE; rstream->corrupted = TRUE; rstream->istream.istream.stream_errno = EINVAL; stream->pos = 0; return -1; } Now, with versions >1.1.3 this won't helps and plugin fails. Anyone knows how to get it working? I would like to upgrade to newest dovecot release Best regards, mr

[Dovecot] Replace Domainname in Mail Location
by Manuel Schmidt 15 Dec '08

15 Dec '08

Hello, I dont fully understand how the domain name replacement in mail_location takes place. If I connect to the server using my username as in the text file i can not access my Maildirs as %d gets not replaced. If i user username(a)domain.com the %d is correctly replaced. But, how would i configure my mail_location, to take the domain part from the server name i connect to? So i could set up my client to connect to mydomain.com and have just my username set as login? I did not find a variable that seems to be more correct than %d. So i guess i have to configure that elsewehre? In userdb?

[Dovecot] Horde IMP w/ dovecot folder list
by LÉVAI Dániel 15 Dec '08

15 Dec '08

Hi! I'm using dovecot-1.1.7, Horde-3.3.2 and IMP-4.3.2. The left-side folder list has some folders, whos names contains localized (non-ascii) characters. This is displayed correctly when I select the "English (American)" language entry on the login page from the dropdown menu. But when I choose my locale, which is "Magyar" (Hungarian), the folders won't display the correct characters. It's like this: With "English (American)" locale: Ügyfél With "Magyar" locale: &ANw-gyf&AOk-l The latter is the same displaying as with the folder's name on the filesystem: # ls -1 user/Maildir/ [...] .&ANw-gyf&AOk-l/ [...] I've sent this message to imp@ but, they say it is a problem with my mailserver, which I suspected, because the wrong folder names are exactly the same as the folder names on the filesystem. Is there any way to solve this? Thanks in advance, Daniel -- LEVAI Daniel PGP key ID = 0x4AC0A4B1 Key fingerprint = D037 03B9 C12D D338 4412 2D83 1373 917A 4AC0 A4B1

[Dovecot] 1.1.7: quota problem, unable to delete mails when quota exceeded

Hi, When user exceeds it's quota then dovecot can't create it's files and it's showing zero mails :( This also means that user is unable to delete it's own mails. Sounds like kind-of bug, right?

[Dovecot] Performance issue about maildir path.
by Zhang Huangbin 15 Dec '08

15 Dec '08

Hi, all. Normally, i use 'domain.ltd/username/Maildir' as users' maildir path, if i change them to hash style, e.g. 'A0/B0/domain.ltd/C0/D0/username/Maildir', will it speed up the index operation for MDA? If we have 10000 users, which maildir path style will improve performance? Thanks very much. :) -- Best regards.

Has anyone used Toltec to connect Outlook to Dovecot hosted message stores? Primary advantage over Bynari is price - $14 per client. I have used it with Kolab and been very happy.

I'm using maildrop to filter mail like: xfilter "/usr/bin/spamc" xfilter "/usr/bin/bogofilter -ep" I want to change to deliver (so I can use sieve) but can deliver do this?

[Dovecot] confused about deliver
by Neal Becker 14 Dec '08

14 Dec '08

I have dovecot serving a maildir in ~/Mail.imap. In Mail.imap I have cur/ new/ tmp/ .maillist1/ .maillist1/cur .maillist1/new .maillist1/tmp ... I made a sieve script, which looks like: require "fileinto"; if header :is "Subject" "test" { fileinto "test"; } ... with no final else clase. When mail is delivered to a maillist, caught by my sieve script, it goes into the correct subdir of maildir. But, when not caught by the script, I get: Dec 14 11:53:27 localhost deliver(nbecker): msgid=<d9f848520812140850q190f104fva5f586e43fa03994(a)mail.gmail.com>: saved mail to INBOX I can't find this mail saved to INBOX. There are no modified directories under maildir that I can find. Where did this mail go? I wanted it to go into the toplevel cur/, which is where my client finds them.

[Dovecot] SIEVE resources ?
by Xavier Maillard 14 Dec '08

14 Dec '08

Hi, Do you any good SIEVE resources for a poor beginnner ? I'd to translate some of my current procmail rules into SIEVE. I have, for example, a "generic" rule that is able to sort almost any message from/to a mailing-list into a dedicated folder -i.e one rule for almost all my lists. Any recomendation ? Thank you

by Mike Abbott 14 Dec '08

14 Dec '08

Hello Dovecot developers, Apple has made and tested significant changes to Dovecot v1.1 and now is ready to contribute them back to your open source project. The changes include: Scalability and performance: allow pop/imap mail processes to handle multiple clients larger listen queues Stability and maintenance: fix to allow cross-compilation workarounds for Mac OS X bugs a couple general bug fixes symbol conflict resolution Features: Open Directory integration back off after failed auth attempts Mac OS X-specific handle dynamic host name changes I could contribute these as one giant patch or as a sequence of discrete patches. How would you prefer to receive them?

[Dovecot] Mailbox name
by Xavier Maillard 14 Dec '08

14 Dec '08

Hi, I am using SIEVE to filter/sort my incoming mails. I am subscribed to tens of mailing lists and I would like to file messages into folder of this pattern: INBOX/list/<tld>/<domain name>/<list name> So for example help-gnu-emacs(a)gnu.org would be filed under: INBOX/list/org/gnu/help-gnu-emacs The problem is Dovecot is telling me that this mailbox name is invalid. What can I do ? Cheers

[Dovecot] Imap logging and inetd
by Jonathan Siegle 14 Dec '08

14 Dec '08

When I ran /usr/local/sbin/dovecot, the variable login_log_format_elements from dovecot.conf was honored. Now when I run /usr/local/libexec/dovecot/imap-login from /etc/inetd.conf, it isn't. How do I get imap-login to write log lines that use login_log_format_elements for the format? This is dovecot-1.2.alpha3 soon to be alpha4. Thanks, Jonathan

[Dovecot] Panic in 1.1.6 file ioloop.c: line 206
by Laurent Blume 14 Dec '08

14 Dec '08

Hi all, I just had a panic with dovecot 1.1.6, two days after replacing 1.0.15 with it in production. Here are the logs immediately preceding the panic, I think they're related. It seems the user connected simultaneously from two different clients, from his own computer and a webmail running on the server, then manipulated mail folders on one side, and logged out. The panic occurred 3 seconds after the logout. Is there a setting I might have missed that could avoid that?

[Dovecot] proxy and master user
by Matthieu Herrb 14 Dec '08

14 Dec '08

Hi For some application we need a master user on our IMAP servers. We use dovecot 1.1.7 in proxy mode, with proxy_maybe (some mailboxes are on the proxy itself, others are on remote servers, also running dovecot). But the proxy removes the '*master' suffix from the username when using the master user to log in on the proxy. So the base name of the user with the master password are submitted to the real server, which of course fails. Is there a way to tell the proxy to forward the master user to the real server, without forcing it in destuser, since we also need to have regular (non master) logins? Thanks in advance. -- Matthieu Herrb

[Dovecot] Broken sorting(?)
by Michael M. Slusarz 14 Dec '08

14 Dec '08

Somewhere between revision f5554ae61732 (12 days ago) and the release of 1.2a4 (f53952ac4285; 9 days ago) sorting appears to have broken. With the older revision, I see the following (using Maildir): a sort (ARRIVAL) US-ASCII ALL * SORT 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 2 1 With the newest code, I see this: a sort (ARRIVAL) US-ASCII ALL * SORT 124 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 2 1 Obviously, that duplicate sequence number (124) is not a good thing (shouldn't the sequence numbers be in order for an arrival search anyway?). Deleting any message in the mailbox always makes the last sequence number appear at the beginning. I can verify that another IMAP server on the same machine views the mailbox just fine: a sort (arrival) US-ASCII ALL * SORT 124 123 122 121 120 119 118 117 116 115 114 113 112 111 110 109 108 107 106 105 104 103 102 101 100 99 98 97 96 95 94 93 92 91 90 89 88 87 86 85 84 83 82 81 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 michael

[Dovecot] Possible bug in Maildir++ quota?
by Ulrich Zehl 13 Dec '08

13 Dec '08

While researching a possible bug in our custom-made Maildir++ expiration script, I found the following in src/plugins/quota/quota-maildir.c. | static const char * | maildir_list_next(struct maildir_list_context *ctx, time_t *mtime_r) | { | [...] | *mtime_r = st.st_size; | return str_c(ctx->path); | } As far as I unterstand, this seems incorrect, because the value in mtime_r is used, for example, in maildirs_check_have_changed to check whether any maildirs or folders have changed. If this isn't a bug, please satisfy my own curiosity and tell me what I'm missing. Ulrich

[Dovecot] fine tuning for 10 users?
by badeguruji 13 Dec '08

13 Dec '08

Hello, How can i fine tune dovecot for less then 10 users? or is there no need? Also, is there any smtp client which can be used with it for a open-source standalone server? i want very-small foot print+secure server, qmail and sendmail are dinos, and i felt xmail is trying to do everything. (as we are less then 10 users here.) i liked round-cube for webmail. i would appreciate all suggestions and pointers. thank you. -B ________________________________
