Sorry, it's just struck me that I've missed out the most important information- I am using maildir++. Sorry :-(. The index files are kept on the shared volume. And to answer the other question again, mmap is off.

Re: [Dovecot] compiling dovecot on aix gcc 3.3.2
by Ralf Becker 05 Apr '07

05 Apr '07

Hello funkypunky drunky, on AIX dovecot plugins (which are shared objects = .so) are a little bit problematic. It is not enough to activate run time linking by using -brtl and make the main program (dovecot) to be able to use shared objects. When a share object does function calls back into the main program, all these functions (=symbols) in dovecot have to be explicitly exported. Otherwise you see "signal 11" or so. Because this is very fiddly, there is a linker flag -bexpall to export all symbols of the main program (dovecot)... but this does seemingly not work with symbols defined in static libraries (.a). While dovecot build creates static libraries to keep the linker command line small, but does *not* generate export files (.exp) containing the libraries globals symbols, the compile time linker does not known anything about them. I think, if dovecot build would use libtool to create the libraries, libtool would export the libraries symbols to fix this. And this is, what my script does. It looks on the compiler command line for library file (.a) and exports all global symbols to an .exp file. The paths of these .exp files are appended to the original compiler command line and so -bexpall knows about the globale symbols defined in the libraries and is able to export them. I don't know if this information is useful for you, because you're using gcc. But if you are using AIX ld (instead of gnu ld) you have to deal with this problem, I think.

[Dovecot] 1.0.rc29 released
by Timo Sirainen 05 Apr '07

05 Apr '07

http://dovecot.org/releases/dovecot-1.0.rc29.tar.gz http://dovecot.org/releases/dovecot-1.0.rc29.tar.gz.sig Probably one more RC after this. * Security fix: If zlib plugin was loaded, it was possible to open gzipped mbox files outside the user's mail directory. + Added auth_gssapi_hostname setting. - IMAP: LIST "" "" didn't return anything if there didn't exist a namespace with empty prefix. This broke some clients. - If Dovecot is tried to be started when it's already running, don't delete existing auth sockets and break the running Dovecot - If deliver failed too early it still returned exit code 89 instead of EX_TEMPFAIL. - deliver: INBOX fallbacking with -n parameter wasn't working. - passdb passwd and shadow couldn't be used as master or deny databases - IDLE: inotify didn't notice changes in mbox file - If index file directory couldn't be created, disable indexes instead of failing to open the mailbox. - Several other minor fixes

[Dovecot] *****SPAM***** The folder 'Inbox' cannot contain items. Namespace problems
by Francisco Reyes 05 Apr '07

05 Apr '07

Several attempts to support both Mac and PCs keep failing. In my latest attempt I used the following settings: #courier-imap compatibility/Thunderbird namespace private { separator = . prefix = INBOX. inbox = yes } For MAC OS Mail.app namespace private { separator = / prefix = INBOX/ inbox = no hidden= yes } This last attempt was based on the suggestion of Timo Sirainen, on the Mac settings. The PC settings were the defaults I got from the sample config and have always worked for PC clients. The new setup with namespace private worked for Mac clients, but got the following error for a number of users in both Outlook and thunderbird. Unable to display the folder. The folder 'Inbox' cannot contain items. This is most likely a limitation of your IMAP server. In order to create a folder that can contain items, be sure to append / to its name as you create it. I see this is an old issue. http://groups.google.com/group/microsoft.public.outlook/browse_thread/thread /5f990142171fb792/62adb6c069946e40?lnk=st&q=%22cannot+contain+items%22+dovec ot&rnum=1#62adb6c069946e40 One interesting point we discovered was that if we set an IMAP account in Outlook the very first time we logged in, it worked. If we closed the client, all subsequent times the "folder Inbox cannont contain items" error would come up. doing a TCPdump showed us that the difference was that the first time that Outlook connects it issued a "Select" command, but all other times it did not. Someone suggested to take out prefix = INBOX. Would that help? I don't want to cause problems for the vast majority of our PC users while trying to fix the Mac clients. Even though Mac users are a minority of our users, it is extremely problematic for us not to be able to support them because many domains may have a handfull of such clients.. so we basically will not be able to host a large number of domains in dovecot machines, just because of a handfull of Mac clients. Currently using Dovecot r27, but have been having this same problem since r15.

[Dovecot] Login lockups
by Daniel L. Miller 04 Apr '07

04 Apr '07

When dovecot works - it works great, and I thank you. But it seems like every time I setup a new server, it's a challenge getting the IMAP logins to work reliably. The changelog's top comment is stamped 2007-01-05, 18:48 if that helps nail down the version (I'm using a Debian/Ubuntu package). Both non-SSL and SSL logins have the problem. This time around I'm using LDAP authentication - and once I figured out how it worked beautifully. The problem is from time to time - with no particular consistency - I lose the ability to log in. A "telnet localhost 143" on the server works with a Dovecot response, then followed with a "01 LOGIN <user> <password>" results in a long delay, then a timeout, with no log files affected. What can I provide to try to trace this? protocols = imap imaps disable_plaintext_auth = no login_process_per_connection = yes -- Daniel

[Dovecot] logfile consistency
by David Lee 04 Apr '07

04 Apr '07

We do some routine logfile (syslog) gathering and analysis. I've been looking at extending this to parse the syslog output of dovecot. Hmmm... Ignoring the leading 'date hostname' prefix, some sample lines are: dovecot: imap-login: Login: user=<uuuuuu>, method=PLAIN, rip=dd.dd.dd.dd, lip=dd.dd.dd.dd dovecot: IMAP(uuuuuu): Disconnected: Logged out dovecot: IMAP(uuuuuu): Disconnected in IDLE dovecot: imap-login: Aborted login: rip=dd.dd.dd.dd, lip=dd.dd.dd.dd dovecot: pop3-login: Login: user=<uuuuuu>, method=PLAIN, rip=dd.dd.dd.dd1, lip=dd.dd.dd.dd dovecot: POP3(uuuuuu): Disconnected: Logged out top=0/0, retr=0/0, del=0/8, size=194970 dovecot: pop3-login: Aborted login: rip=dd.dd.dd.dd, lip=dd.dd.dd.dd deliver(uuuuuu): msgid=<014089712.74355909944644(a)thhebat.net>: saved mail to INBOX I've obfuscated some of the local detail: uuuuuuu represents a username/identifier; dd.dd.dd.dd represents an IP address. Would it be possible, please, to consider improving the consistency of the logging information? For instance: 1. All lines, including the "deliver", to begin "dovecot:"; 2. The "IMAP(uuuu): Disconnected" to become "imap: disconnected user=<uuuu>"; Overall this would make it more consistently amenable to perl-like pattern processing, at least with a reasonably hierarchical structure to the messages. Perhaps something like: dovecot: subprogram: event, key1=value1, key2=value2 ... where: "subprogram" is "{imap,pop,deliver,...}"; "event" is "{login,disconnected, ...}; and one of the "key=value" will usually be "user=<uuuu>". That would really make post-processing of logging information (whether offline, or 'live' via piped syslog) considerably easier. Thanks. -- : David Lee I.T.

[Dovecot] How to integrate dspam and dovecot
by Manilal K M 03 Apr '07

03 Apr '07

Hello all, I am currently setting up a new mail server with Qmail, OpenLDAP and Dovecot in CentOS-4.4. Qmail version is 1.03, OpenLDAP is 2.3 and Dovecot version is dovecot-1.0-3_50.rc27(RPM). I have successfully installed and tested it. But I have two issues with the current setup: #1. I am using dovecot LDA and configured the OpenLDAP such that the mail be delivered to the virtual users through a script. This script is saved in /var/qmail/bin/deliver.sh and the contents is as follows: /usr/bin/dspam --stdout --mode=tum --deliver=innocent,spam --feature=chained,noise --user global |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d $RECIPIENT || exit 77 This script name is mentioned in each user's deliveryProgramPath in the LDAP. I am not sure whether this is the best approach of using dovecot as MDA. I tried to include the following contents in /var/qmail/control/defaultdelivery : |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d $RECIPIENT But it seems that this is not working as desired. Please comment, if I have gone wrong anywhere. #2: I wish to use dspam to filter out the spam messages, but I am unsure whether the dspam plugin mentioned in http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration is already in the dspam version I am using. If it's available please give details to configure it. Kindly share ideas. regards Manilal. -- Better to light one candle than to curse the darkness.

[Dovecot] No CA names sent in TLS handshake
by Johnny Chadda 03 Apr '07

03 Apr '07

Hello, I'm setting up Dovecot with client certificates and everything is working fine as long as the client only has one certificate in his store. If he has more than one, the wrong one might be sent to the server. The root of the problem is that Dovecot does not send out a list of valid CA names in the TLS handshake. If I connect using openssl s_client I get: "No client certificate CA names sent" I am using Dovecot 1.0 RC15 from backports.org. Is there a solution to this problem? Regards, Johnny

[Dovecot] *****SPAM***** Upgrading from rc27 to rc29?
by Francisco Reyes 03 Apr '07

03 Apr '07

After sending a messasge about a problem (The folder 'Inbox' cannot contain items. Namespace problems) I found what seems to be a fix in the release for rc29. Besides any potential configuration files, do I need to delete the old index files? Any of the dovecot files? Based on the release notes for rc29 it seems the following will fix the problem we are experiencing: IMAP: LIST "" "" didn't return anything if there didn't exist a namespace with empty prefix. This broke some clients.

[Dovecot] [PATCH] to fix 2 pam issues
by Phil Oleson 03 Apr '07

03 Apr '07

Timo, I finally made the time to backport a pam fix I created for proftpd over to dovecot, that allows FreeBSD's pam_group to work as expected. (the bug was escalated to me internally hehe.. ). I also noticed an issue while testing that will be confusing to users. If the docs stay as is, or the other half of this patch is applied, then when the dovecot.conf contains: passdb pam { args = * } the imap files within etc/pam.d right now have to be named 'IMAP' and 'POP3' rather than the expected 'imap' and 'pop3'. The attached patch fixes the code to match the docs. -Phil. --- src/auth/passdb-pam.c.orig Mon Mar 26 10:10:26 2007 +++ src/auth/passdb-pam.c Mon Apr 2 16:18:54 2007 @@ -275,6 +275,8 @@ (void)pam_set_item(pamh, PAM_RHOST, host); /* TTY is needed by eg. pam_access module */ (void)pam_set_item(pamh, PAM_TTY, "dovecot"); + /* FreeBSD's pam_group need this set as well */ + (void)pam_set_item(pamh, PAM_RUSER, request->user); status = pam_auth(request, pamh, &str); if ((status2 = pam_end(pamh, status)) == PAM_SUCCESS) { @@ -428,8 +430,15 @@ int fd[2]; pid_t pid; - service = module->service_name != NULL ? - module->service_name : request->service; + if (module->service_name != NULL) { + service = module->service_name; + } else { + if (!strncmp(request->service, "IMAP", strlen(request->service))) + service = "imap"; + else if (!strncmp(request->service, "POP3", strlen(request->service))) + service = "pop3"; + } + auth_request_log_debug(request, "pam", "lookup service=%s", service); if (worker) {

[Dovecot] vpopmail "last auth" question
by B. Cook 03 Apr '07

Hello, I run the domain for the school here with qmail and vpopmail on FreeBSD with dovecot from the ports. I'm running dovecot 1.0.r26 and everything is working great.

[Dovecot] Suggestion: mod_auth_dovecot
by David Anderson 03 Apr '07

03 Apr '07

Hello, I have a suggestion which might be a small and very useful project for a C coder (I'm not one!). As Dovecot makes its authentication interface available to other programs, I think that an Apache module to use it would be very useful. Currently I share an passwd-db file between Dovecot and Apache. However with Apache that means I have to give Apache read access. That means that websites with PHP could read that password file if they liked. If Apache could talk to the Dovecot authentication process instead, that would be a lot better. I'm sure there are lots of situations in which this would be useful - Dovecot's authentication settings are so flexible that it would be very handy to be able to use them more widely. If anyone produces one, I pledge to produce an RPM package and submit it to Fedora as my contribution. I would do it myself if I knew C... David

[Dovecot] prefetch + static + deliver
by Tom Bombadil 02 Apr '07

02 Apr '07

Hi all... The prefetch entry in the wiki says: "If you're using Dovecot's local delivery agent, you'll still need a valid userdb which it can use to locate the users. You can do this by adding a normal sql/ldap userdb after userdb prefetch." (http://wiki.dovecot.org/UserDatabase/Prefetch) My question is: Does it need to be a SQL/LDAP userdb? How about static or passwd? Thanks in advance :)

[Dovecot] testing LDAP connections
by Hugo Monteiro 02 Apr '07

02 Apr '07

Hello all, I haven't looked into the source code, but i suspect that LDAP connections, once established, are not tested properly. My scenario is the followind: Dovecot server <--------> firewall <---------> LDAP backend What happens is that the firewall has a security feature which basically make de firewall box "forget" about connections that are idle for more than X period of time. That particular setting is 30 minutes right now. When that happens, neither the LDAP backend or the Dovecot server get any type of notification, and for all they care the connection is alive and well. This is a very common implementation in firewalls nowadays. So my question is, is there any way to make dovecot re-open a new connection if there is a timeout while trying to use a connection already opened? I believe that this could be of great benefit for those who don't have their servers on the same physical network.

[Dovecot] Using Dovecot LDA with Sendmail
by Scott Peron 02 Apr '07

02 Apr '07

Hi all, After looking at the LDA/Sendmail page in the dovecot wiki, I wanted to contribute another method to easily configure Sendmail to use deliver. Instead of adding a new mailer definition, as already suggested, one can simply use the following line in their sendmail.mc file instead: FEATURE(`local_procmail', `/usr/libexec/dovecot/deliver', `deliver -d $u', `SPhnu9')dnl And further on, still use: MAILER(procmail)dnl The location of deliver will of course vary for each OS and distro, etc, but this redefines the "procmail" mailer in the resulting sendmail.cf to use deliver instead, with the correct flags. For most setups, I believe this is the simplest configuration path.

[Dovecot] Unexpected behaviour when deleteing a big mailbox
by Steffen Kaiser 02 Apr '07

02 Apr '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, my last tests left me with a mailbox with > 80'000 messages in Maildir. Dovecot served them fine. No problem. I usually use IMAP's "Mark messages a deleted" function and expunge later. Because the "Move to Trash" is default in many MUAs, I decided to try it on this mailbox. I do think that it is hard to detect and prevent such problem, but could it be implemented that when the client connection times out, the COPY process is terminated and rolled back? I mean, as long as the messages are copied/linked to */tmp nothing is done, yet, hence, a simple cleanup of */tmp would result in a rollback. Due to the timeout, the EXPUNGE wasn't issued so far and the source mailbox is unchanged. Or, is it possible to prevent two COPYs of an overlapping message range into the same destination folder simultaneously? Or, can I prevent to COPY such a huge range of messages at once? I know 80'000 messages are much, but I have users with an INBOX of at least 40'000, eventually moving all files into an archive mailbox. I'm also surprised to find that I didn't get two full copies of the source mailbox. ============== Start situation: 4.8G .box1 (I didn't recorded the individual subdirs, unfortunately.) # find .box1 -type f | wc -l 84273 Newly created .Trash. === I started Thunderbird, let sync the mailbox, selected them all, and pressed "Delete". Some time later: Connection timed out. I, wondered, and hit "Delete" a second time. Again, connection timed out. === I was surprised, however, to see that the Dovecot log with still active telling me that mails are copied to Trash. I ended up with two processes copying all messages to .Trash/tmp on the server. The process I traced a bit later linked any file after the other. What I wondered right from the beginning was, that du -hs .??* displayed about 3.5GB in .Trash, but still 4.8GB in .box1. So, why are there 3.5GB additional files in .Trash, when I configured Dovecot to use hardlinks? The end situation is that .box1 contains all messages still, but any Unseen messages are moved to .box1/cur, and .Trash contains: 7.4G .Trash/cur 791M .Trash/new 76K .Trash/tmp # find .Trash/ -type f | wc -l 121713 The size nearly doubled. # du -hs .box1 ; du -sh .Trash/ 4.8G .box1 8.2G .Trash/ ==== Last lines in Dovecot log: dovecot: Mar 21 11:46:15 Info: IMAP(dvtest) [11535]: copy -> Trash: uid=83964, msgid=<xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx(a)xx-xxxx-xxxxx-xxxx.xx>, box=box1 dovecot: Mar 21 11:46:15 Info: IMAP(dvtest) [11535]: copy -> Trash: uid=83965, msgid=<xxxxxxxx.xxxxxxx(a)xx-xxxx-xxxxx-xxxx.xx>, box=box1 dovecot: Mar 21 11:46:29 Info: IMAP(dvtest) [11535]: Disconnected: Mailbox is in inconsistent state, please relogin.

[Dovecot] imaptest10 and stalled messages
by Mike Brudenell 01 Apr '07

Greetings - I've now got as far as playing with the imaptest10 test utility to see if I can stress-test our development server. imaptest10 is built against dovecot-1.0rc28 It may just be that I'm excessively heavy handed, but when I let imaptest10 rip with the command... ./imaptest10 user=test%03d host=testserver.imap.york.ac.uk clients=50 mbox=./dovecot.mbox msgs=1000 secs=30 logout=10 ...after 15 seconds or so I started getting output along the lines of: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 10% 30% 5% 2 0 1 1 1 0 0 0 0 0 0 50/ 50 2 0 0 1 1 0 0 0 0 0 0 50/ 50 0 0 2 2 0 1 1 1 1 1 0 50/ 50 2 0 2 2 0 1 1 1 1 1 2 50/ 50 0 0 1 1 0 0 0 0 0 0 0 50/ 50 - 16. stalled for 16 secs in LOGIN - 17. stalled for 16 secs in LOGIN - 18. stalled for 16 secs in LOGIN 2 1 1 2 1 0 0 0 0 0 0 50/ 50 - 17. stalled for 17 secs in LOGIN - 18. stalled for 17 secs in LOGIN - 22. stalled for 16 secs in LOGIN - 23. stalled for 16 secs in LOGIN - 24. stalled for 16 secs in LOGIN 1 0 1 1 0 0 0 0 0 0 0 50/ 50 - 17. stalled for 18 secs in LOGIN - 18. stalled for 18 secs in LOGIN - 22. stalled for 17 secs in LOGIN - 23. stalled for 17 secs in LOGIN - 24. stalled for 17 secs in LOGIN - 28. stalled for 16 secs in LOGIN - 29. stalled for 16 secs in LOGIN - 30. stalled for 16 secs in LOGIN - 31. stalled for 16 secs in LOGIN - 32. stalled for 16 secs in LOGIN The "stalled" log lines continue until the test completes. I'm assuming it's just that I'm pushing our hardware beyond its reasonable limits: it is only an oldish development box... Sun v120 with 1 650MHz SPARC processor and 1Gbyte RAM Dovecot is using shadow password file authentication. The mail folders are in Maildirs, NFS-mounted from a NetApp filer, and each account's INBOX has around 1000 messages in it. Control and Index files are on local disk. By the end of the 30 second test run load average has climbed to around 11 I don't know how "active" the imaptest10 utility is when it's running, but do you think I should be concerned by the "stalled" messages? That is, do you think I have something configured amiss? Or is it likely just to be I'm expecting too much of our hardware? (The real system will have beefier Suns with Opteron-based CPUs, more memory, etc) With thanks, Mike B-) PS. I forgot to say: despite all this activity there's not a single error logged by Dovecot in the (admittedly short at this stage) test runs. -- The Computing Service, University of York, Heslington, York Yo10 5DD, UK Tel:+44-1904-433811 FAX:+44-1904-433740 * Unsolicited commercial e-mail is NOT welcome at this e-mail address. *

[Dovecot] locking question
by Stewart Dean 01 Apr '07

01 Apr '07

There are three applications that have their mitts on files on my mail server, which is running AIXV5.3 and UWIMAP and mbox format. The mail folders and INBOXES are native to that machine, but also are NFS exported to a login server and a mailing list server. All three machines are running the lockd daemon. Everybody wants to lock differently 1) procmail (delivering for sendmail), which seems to want to use dotlocking, fcntl and lockf locking; for whatever reasons, the compile time tests seem to disallow flock. 2) UWIMAP which according to wiki.dovecot.org/Migration/UW uses: mbox_read_locks = flock mbox_write_locks = dotlock flock 3) I want to run dovecot in the same environment as I switch over, for which the locking strategy is supposed to be (according to http://wiki.dovecot.org/MboxLocking) mbox_read_locks = fcntl mbox_write_locks = dotlock fcntl Since that same page in the wiki says. "*It's important that all software that's reading or writing to mboxes use the same locking settings.",* I had recompiled procmail so it only usedotlocking and fcntl (thus removing lockf in addition to the disallowed flock)...but now I bumped into the Migration/UW page and there looks to be a conflict. I want to be able to run dovecot (for testing) and UWIMAP (for all users/production) at the same time (but never at the same time with the same mailbox), but UWIMAP is doc'ed to use flock and Dovecot doesn't It's conceivable that the different locking strategies of UWIMAP and Dovecot don't matter because they would never be going after the same mail files (right?) but there is procmail, which has to interact with both. It appears to not use flock OK, even though the docs say it should since UWIMAP expects it, and I've disabled lockf as well. But will there be a conflict with procmail and dovecot's use of fcntl, which UWIMAP doesn't use?

[Dovecot] 1.0rc29: Corrupted index cache file
by Jeff Rice 01 Apr '07

01 Apr '07

Hi, I have recently migrated from Courier to Dovecot, and I noticed a problem in one of my spam scripts. Here's the setup: Spam that needs to be retrained by the filter is placed in a maildir from the IMAP client. A cron job scans that maildir and if it finds a message, feeds it to the spam filter and removes it from the training maildir. Depending on whether or not the message was a spam or ham, it is either deleted or delivered to Inbox. It appears I am getting an error when the script deletes a mail message. I haven't checked if this message only occurs when a client is connected -- it's possible. Log excerpt: Mar 31 18:34:57 finity dovecot: IMAP(XXXXXXX(a)finity.org): Maildir /home/vmail/XXXXXXX(a)finity.org/.Spam.Unsure sync: UID inserted in the middle of mailbox (8 > 3, file = msg.FHoB:2,) Mar 31 18:34:57 finity dovecot: IMAP(XXXXXXX(a)finity.org): Disconnected: Mailbox is in inconsistent state, please relogin.

[Dovecot] convert plugin failing
by Adrian Bridgett 31 Mar '07

31 Mar '07

I'm struggling to get the convert plugin working using the Debian etch packages. When starting dovecot it was trying to create files in /.temp.hostname... convert-plugin.c looks like it has a couple of typos in it - it checks "mail" three times for NULL rather than mail, user, home. I changed this but it's getting called when these three items are set to: "maildir:/HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB/Maildir" "dump-capability" "" I must be missing something - shouldn't the mailboxes only be converted when a user logs in? Should the conversion be skipped for the dump-capability user (whatever that is!) Thanks, Adrian -- Adrian Bridgett - adrian(a)smop.co.uk GPG key available on public key servers

Hi all, Merging the two large recent threads, my recommendation is as follows: * The Release Candidates for 1.0 should be bug fixes only. * Each new Feature, or a Feature Set, goes in a separate branch. * That branch is tested by those who need/want that feature. * When testing is completed, the branch is merged into the main trunk. This way, we will have fairly well tested features/feature sets in the main trunk which people can fairly safe download and test and deploy, if their own tests succeeds. When the feature code is merged into the main trunk, the minor version is incremented by one (1.0.x --> 1.1.0). Bug fixes increment the revision (1.1.0 --> 1.1.1). Easy to follow, easy to package for package maintainers. Also, it's easy to write Readme's and other documentation on what's changed. (And for those who think that odd versions are for development (unstable), well, they will just wait until sufficient features have been added before they think it is stable... ) Timo's new features he sees for future versions, plan them for a 2.0 or a 1.1 or whatever version number, just don't call it 1.0.2rc1 :-) Another suggestion, is to create a Bugzilla (or similar) site for dovecot. That gives us all a chance to track changes and bug fixes. /Peter, building rc29 as I write this

[Dovecot] rc28 : can't set quotas with userdb + passwd file
by David Anderson 30 Mar '07

30 Mar '07

I'm using dovecot 1.0 rc28 - great software! I have a virtual hosting setup, with passdb and userdb both using a passwd file. I cannot get per-user quotas put in the relevant field of the userdb to work. They appear to be completely ignored; only the setting from /etc/dovecot.conf is applied. Can anyone confirm that this is working for them? If it is, can you post the relevant bits of your configuration, please? Many thanks. Kind regards, David

[Dovecot] Freebsd 4 error DSN stat=Service Unavailable after dovecot install

Hello everyone, I am getting an error message on FreeBSD 4 after I install dovecot. To start off, I create two regular users, testuser and testuser1. I send each user emails then I install dovecot. After installing dovecot I set up the users in Maildir format then proceed to send them emails and here is what shows up in the maillogs: Email to testuser3 - Mar 29 22:34:52 myserver sendmail[4379]: l2TMYqwj004379: from=root, size=54, class=0, nrcpts=1, msgid=<200703292234.l2TMYqwj004379(a)myserver.vwh.net>, relay=r oot@localhost Mar 29 22:34:52 myserver sm-mta[4380]: l2TMYqMi004380: from=<root(a)myserver.vwh.net>, size=342, class=0, nrcpts=1, msgid=<200703292234.l2TMYqwj004379@myserver .vwh.net>, proto=ESMTP, daemon=MTA-v4, relay=localhost [127.0.0.1] Mar 29 22:34:52 myserver sendmail[4379]: l2TMYqwj004379: to=testuser3(a)myserver.vwh.net, ctladdr=root (0/0), delay=00:00:00, xdelay=00:00:00, mailer=relay, pr i=30054, relay=localhost..

[Dovecot] Security hole #3: zlib plugin allows opening any gziped mboxes
by Timo Sirainen 30 Mar '07

30 Mar '07

zlib plugin allows opening gzipped mboxes as read-only mailboxes. However when using it, the mailbox name checks are bypassed so it's possible to open for example "../otheruser/somefile.gz". Only valid gzipped mbox files can be opened, and only if their name ends with ".gz". You can fix this by upgrading to v1.0.rc29 (available soon) or with this patch: http://dovecot.org/list/dovecot-cvs/2007-March/008488.html I don't think this matters much though. zlib plugin is rarely used, and those who do use it are probably using Dovecot with systems users (per-user UIDs), so the imap process wouldn't have access to other users' mbox files anyway. I found this problem when I was cleaning up the code in CVS HEAD.

[Dovecot] uiddir mailbox format with benchmarks
by Timo Sirainen 30 Mar '07

30 Mar '07

I cleaned up the lib-storage code a bit so that it's easier to write support for new mailbox formats. It could still use a bit of cleaning up. Anyway, I thought I'd try how easy it would be to implement Cyrus-like mail store which would consist of only Dovecot's index files and "<uid>." message files. Flags and everything else is kept only in Dovecot's index files (so it might not be the best idea to use it in production just yet). Several hours later I ended up having it working. The code contains: ~/cvs/m/dovecot-head/src/lib-storage/index/uiddir% wc *[ch] 144 329 3552 uiddir-mail.c 240 565 6206 uiddir-save.c 532 1367 13628 uiddir-storage.c 55 126 1712 uiddir-storage.h 169 404 4057 uiddir-sync.c 21 48 573 uiddir-sync.h 103 258 2762 uiddir-transaction.c 1264 3097 32490 total uiddir-storage.c is still a bit too bloaty with lots of copy&pasted code. The same with maildir and mbox: maildir: 6022 18232 165605 total mbox: 7859 23283 213686 total Benchmarks show that with small mailboxes it's a lot faster than maildir, and with larger mailboxes it's a bit faster. I also tested it against Cyrus. I found out that fetching ENVELOPE vs. specific headers gives quite a huge performance difference. Cyrus is optimized for ENVELOPE while Dovecot is optimized for specific headers. With larger mailboxes + ENVELOPE Cyrus is faster than Dovecot, while with specific headers Dovecot is always faster. Maybe I'll some day make Dovecot optimize for ENVELOPE also if it sees that client only wants to use it. BTW. Does anyone have better naming ideas than "uiddir"? I'll commit it to CVS HEAD once I'm sure about the name. :) u: Dovecot CVS HEAD + uiddir m: Dovecot CVS HEAD + Maildir c: Cyrus IMAP 2.2.13 ./imaptest list=0 seed=1 secs=60 clients=10 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 23486 11822 23481 23476 33426 11659 8038 23472 11922 46952 m: 19367 9734 19367 19356 27453 9687 6287 19347 7983 38709 c: 5124 2553 5121 5105 7080 2559 1877 5104 3271 10228 ./imaptest list=0 dele=20 expu=20 seed=1 secs=60 msgs=10000 clients=10 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 5291 2704 5289 5278 7448 2706 1048 1061 5283 10563 m: 4162 2103 4162 4153 5977 2124 762 853 4153 8304 c: 4302 2157 4301 4289 6021 2072 806 879 4292 8584 ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=10 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 3211 1637 3206 3195 4639 1537 287 302 3202 6402 m: 2957 1508 2955 2944 4173 1440 279 306 2948 5894 c: 3933 1929 3933 3920 5604 2020 380 379 3923 7846 ------ ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=1 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 1529 745 1529 1528 2184 819 136 162 1528 3056 c: 1579 813 1579 1578 2257 811 171 148 1578 3156 ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=50 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 3098 1552 3093 3085 4432 1520 293 334 3089 6173 c: 3664 1765 3659 3596 5106 1802 365 364 3614 7228 ====== FETCH BODY.PEEK[HEADER.FIELDS(from to cc subject)] instead of ENVELOPE: ./imaptest list=0 dele=20 expu=20 seed=1 secs=60 msgs=10000 clients=10 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 5777 2933 5777 5767 8215 2901 1133 1191 5767 11531 c: 3636 1794 3635 3623 5196 1843 682 722 3627 7254 ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=10 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 3869 1959 3868 3861 5452 1943 364 394 3859 7717 c: 3191 1620 3189 3184 4501 1598 315 327 3181 6362 ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=1 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 1912 966 1912 1910 2783 940 184 197 1911 3820 c: 1342 696 1342 1341 1888 682 109 126 1341 2682 ./imaptest list=0 dele=10 expu=10 seed=1 secs=60 msgs=100000 clients=50 Logi Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo u: 4618 2320 4610 4604 6558 2266 452 455 4605 9205 c: 2960 1472 2956 2941 4134 1425 281 312 2910 5820

[Dovecot] sieve-body extension support for deliver LDA's sieve plugin
by Scott Peron 30 Mar '07

30 Mar '07

Hi Timo & Co, Is there any time frame for updating the deliver LDA's sieve plugin code to that from Cyrus IMAPd v2.3.x? I ask as I'm looking for the functionality of the sieve-body extension, as described here: http://www.ietf.org/internet-drafts/draft-ietf-sieve-body-06.txt This requirement has come up as we're upgrading from a Courier-IMAP/maildrop configuration that has some filtering based on message body content. As an aside, if that time frame is undefined or will be long, if I use maildrop instead as my LDA, will I loose the instant delivery notification via IMAP IDLE? Thanks very much, Scott -- Scott Peron, Webmaster, Infolytica Corp. webmaster(a)infolytica.com Tel: (514) 849-8752 x269 Fax: (514) 849-4239 http://www.infolytica.com Place du Parc, 300 Leo-Pariseau, Suite 2222, Montreal, QC, Canada, H2X 4B3

[Dovecot] Version numbering
by Timo Sirainen 30 Mar '07

30 Mar '07

After v1.0 is released, I can finally get back to sane version numbers. But any comments on which one is better: a) Postfix-style: "1.1.UNSTABLE.YYYYMMDD" -> 1.1.0 (stable) b) Odd-even numbering: 1.1.x (unstable) -> 1.2.0 (stable) With a) style the releases could be done by simply copying a nightly snapshot to releases/ directory and announcing the changes since the last release. I'm not sure if that's good or bad.

Have the RC's released new features as well as fixed bugs? I've been hesitant to upgrade to an RC because they seem to be released so frequently and I have no idea if one is more or less stable than another. This uncertainty is a big show-stopper to upgrading. It would help if, for a given RC, we knew exactly what known issues that RC had. (Is that in the wiki?) I'd suggest that a "version" be assigned only to something that should get spread around. A nightly snapshot should get the version it was based from and a timestamp suffix of when it was extracted from CVS. (Were this Subversion, I'd append the repository revision, instead.) The snapshot is not a "version" but a convenient download from CVS. It should be exactly what you get with the same timestamp used in a checkout command. Apache's versioning scheme (posted by John Peacock) looks good to me: <http://apr.apache.org/versioning.html>

[Dovecot] Forbidding folder delete
by Kenneth Porter 30 Mar '07

30 Mar '07

Is there some way I can forbid the deleting of folders? I have a Thunderbird user who twice now has accidentally deleted a folder, forcing me to go fetch it from the nightly backup. I'd like to prevent this from happening again, and the easiest way to me is to block folder deletion. I'd rather do that "manually" from the shell than leave it available from the client GUI.

[Dovecot] Copy to sent mail timeouts
by Jeff Tucker 29 Mar '07

29 Mar '07

Hi. I'm running the dovecot IMAP that comes with Ubuntu Edgy, which is 1.0rc2. I realize this is old, but I'll ask my question in case anyone knows about this problem and how to fix it, or knows that a later version definitely fixes it. What I'm seeing is that the IMAP server works perfectly, except for occasional timeouts when the user sends an email with attachments, causing that email then to be copied to their sent mail folder. The behavior seen is that Thunderbird, for instance, will say it is copying to the sent mail and the progress goes up to 100%, but then stops and Thunderbird eventually says the action timed out. I don't see anything in any dovecot logging and the file does not appear in the sent mail. I don't have any other kind of timeout issues. I can move mails around folders, read large emails, or whatever. The problem seems worse with large emails, but some times it will copy 15 MB emails and some times it won't. I can't find that any particular email always fails. Any ideas? As a last resort, I'll build the latest rc from scratch, but I like the automatic installation, notification of security problems, etc. I get with the distro packages. Thanks Jeff

[Dovecot] chroot and raw logging

I'm not sure if it's even intended to work in this particular case, but there's a problem when chroot is explicitely defined and rawlogging is used. Rawlog respects chroot point, without being actually chrooted. Consider configurtion as below, with two cases (dovecot.rawlog dir is of course created earlier, with appropriate uid/gid). 1) dovecot.userdb: test::10000:10000::/home/vmail/test.tld/test/./::userdb_mail=maildir:~/Maildir: ktrace will show: 18206 rawlog CALL sigprocmask(0x3,0) 18206 rawlog RET sigprocmask -65793/0xfffefeff 18206 rawlog CALL lstat(0x81fbe028,0xcfbcc980) 18206 rawlog NAMI "/dovecot.rawlog" 18206 rawlog RET lstat -1 errno 2 No such file or directory 18206 rawlog CALL sigprocmask(0x1,0xffffffff) 2) dovecot.userdb: test::10000:10000::/home/vmail/test.tld/./test::userdb_mail=maildir:~/Maildir: 1116 rawlog CALL lstat(0x85768028,0xcfbc1d20) 1116 rawlog NAMI "test/dovecot.rawlog" 1116 rawlog RET lstat -1 errno 2 No such file or directory 1116 rawlog CALL sigprocmask(0x1,0xffffffff) 1116 rawlog RET sigprocmask 0 I also noticed something else (not rawlog related). If I do a silly (blame my curiosity ;) thing like: valid_chroot_dirs: / and set chroot point as /./home/vmail/test.tld/test/ in passwd-file Dovecot will try to stat home/vmail/test.tld/test/ (and fail w/o beginning /), then chdir to /tmp, start pop3 or imap process, and recreate home/vmail/test.tld/test under /tmp. 17027 dovecot CALL chdir(0x87a4b29c) 17027 dovecot NAMI "home/vmail/test.tld/test/" 17027 dovecot RET chdir -1 errno 2 No such file or directory 17027 dovecot CALL setitimer(0,0xcfbe7020,0xcfbe7010) 17027 dovecot RET setitimer 0 17027 dovecot CALL seteuid(0) 17027 dovecot RET seteuid 0 17027 dovecot CALL chdir(0x3c001b72) 17027 dovecot NAMI "/tmp" 17027 dovecot RET chdir 0 ... 17027 dovecot CALL sigprocmask(0x3,0) 17027 dovecot RET sigprocmask -65793/0xfffefeff 17027 dovecot CALL execve(0x87a4bc38,0x87a4bc70,0x84fdb900) 17027 dovecot NAMI "/usr/local/libexec/dovecot/pop3" ... 17027 pop3 CALL mkdir(0x85f5a2b0,0x1ff) 17027 pop3 NAMI "home/vmail/test.tld/test//Maildir" 17027 pop3 RET mkdir -1 errno 2 No such file or directory 17027 pop3 CALL mkdir(0x85f5a2e0,0x1ff) 17027 pop3 NAMI "home/vmail/test.tld/test/" 17027 pop3 RET mkdir -1 errno 2 No such file or directory 17027 pop3 CALL mkdir(0x85f5a328,0x1ff) 17027 pop3 NAMI "home/vmail/test.tld/test" 17027 pop3 RET mkdir -1 errno 2 No such file or directory 17027 pop3 CALL mkdir(0x85f5a348,0x1ff) ... and so on, then it creates all the home/vmail/... dirs Configuration: openbsd 3.9, i386, dovecot 1.0-rc28 dovecot.userdb: test::10000:10000::/home/vmail/test.tld/test/./::userdb_mail=maildir:~/Maildir: dovecot.passdb: test:{PLAIN}test: base_dir: /var/dovecot/ protocols: imap imaps pop3 pop3s ssl_listen: * ssl_ca_file: /etc/ssl/cert_bundle.pem ssl_cert_file: /etc/ssl/ca_ppgk/certs/fetch_crt.pem ssl_key_file: /etc/ssl/ca_ppgk/private/fetch_key.pem verbose_ssl: yes login_dir: /var/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: Dovecot IMAP server ready. login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no valid_chroot_dirs: /var/mail:/home/regular:/home/vmail verbose_proctitle: yes first_valid_uid: 1999 first_valid_gid: 10 mail_location: mbox:~/Mail:INBOX=/var/mail/%u mail_debug: yes fsync_disable: yes lock_method: fcntl maildir_copy_with_hardlinks: yes mbox_read_locks: fcntl mbox_write_locks: fcntl mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/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 auth default: mechanisms: plain login verbose: yes debug: yes passdb: driver: passwd-file args: /etc/dovecot.passdb passdb: driver: bsdauth userdb: driver: passwd-file args: /etc/dovecot.userdb userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master:

I expected: * PAM authentication would not be attempted * passwd-file would provide gid, uid, home, mail I notice that even thought it appears that this information is returned from auth(default) in the IMAP(randykahle) phase, it is not using that information - it used uid=502, etc. Here is my log output: ----- Mar 29 05:59:08 kahle dovecot: auth(default): pam(randykahle, 72.211.130.251): lookup service=dovecot Mar 29 05:59:08 kahle dovecot: auth(default): pam(randykahle, 72.211.130.251): pam_authenticate() failed: Authentication failure Mar 29 05:59:08 kahle dovecot: auth(default): passwd-file /etc/ dovecot/userdb: Read 1 users Mar 29 05:59:08 kahle dovecot: auth(default): passwd-file(randykahle, 72.211.130.251): lookup: user=randykahle file=/etc/dovecot/userdb Mar 29 05:59:08 kahle dovecot: auth(default): client out: OK 1 user=randykahle home=/var/mail/vhosts/com.rosalita/ randy mail=maildir:~/Maildir uid=5000 gid=5000 Mar 29 05:59:08 kahle dovecot: auth(default): master in: REQUEST 26 11935 1 Mar 29 05:59:08 kahle dovecot: auth(default): passwd(randykahle, 72.211.130.251): lookup Mar 29 05:59:08 kahle dovecot: auth(default): master out: USER 26 randykahle system_user=randykahle uid=502 gid=502 home=/ home/randykahle Mar 29 05:59:08 kahle dovecot: IMAP(randykahle): Effective uid=502, gid=502, home=/home/randykahle Mar 29 05:59:08 kahle dovecot: IMAP(randykahle): maildir: access(/ home/randykahle/Maildir, rwx): failed: No such file or directory Mar 29 05:59:08 kahle dovecot: IMAP(randykahle): maildir: couldn't find root dir Mar 29 05:59:08 kahle dovecot: IMAP(randykahle): mbox: root exists (/ home/randykahle/mail) Mar 29 05:59:08 kahle dovecot: IMAP(randykahle): mbox: INBOX exists (/ var/mail/randykahle) Mar 29 05:59:08 kahle dovecot: IMAP(randykahle): mbox: root=/home/ randykahle/mail, index=/home/randykahle/mail, inbox=/var/mail/randykahle Mar 29 05:59:08 kahle dovecot: imap-login: Login: user=<randykahle>, method=PLAIN, rip=72.211.130.251, lip=72.249.22.55 Mar 29 05:59:11 kahle dovecot: IMAP(randykahle): open(/var/ mail/.temp.kahle.org.11965.76100dca2c5b2009) failed: Permission denied Mar 29 05:59:11 kahle dovecot: IMAP(randykahle): file_lock_dotlock() failed with mbox file /var/mail/randykahle: Permission denied Mar 29 05:59:16 kahle dovecot: IMAP(randykahle): Disconnected ----- Here is my passwd-file user information line: ----- randykahle:{plain}xxxxx:5000:5000::/var/mail/vhosts/com.rosalita/ randy::home=/var/mail/vhosts/com.rosalita/randy mail=maildir:~/ Maildir uid=5000 gid=5000 ----- Any tips on how to get the information in the passwd-file used by the IMAP process would be appreciated. -- Randy

[Dovecot] can't receive mail from other hosts
by carpenter＠strongs.org 29 Mar '07

29 Mar '07

i'm running RHEL v 5 and 1.0-1.2.rc15 of dovecot and 2.3.3-2 of postfix. users can send mail to outside hosts, but can not receive them. i find no errors in the maillog -- i used a page from the redhat docs to configure postfix and dovecot so that they used the same mail directory... i think... any ideas on how to debug and/or fix this would be greatly appreciated. thanks, steve

[Dovecot] New mail not appearing consistently in Outlook 2003
by Karl von Randow 29 Mar '07

29 Mar '07

Hi all, I have continuously experienced a new mail not appearing problem in Outlook 2003 on Windows XP. Using Dovecot 0.99.14 on Debian Sarge and now in 1.0rc26 and rc27. The problem exhibits itself as: Some new mail is randomly(?) not shown in my mailbox. More new mail does appear, so it's difficult to know when a message has been missed. If I restart Outlook the missed new messages will appear as unread in the order where they should have been received in my inbox. I use secure imap. I get email through my inbox (receipts from a website we're testing, at its peak maybe 2-3 a minute) that are moved into another mailbox using a rule in Outlook. These are often the messages that are missed as above, but it often includes other email as well. The mail box format is mbox on the server. The mail delivery is by exim4 from Debian Sarge. I wondered if there was a locking problem between exim4 and dovecot? My transport in exim4 for delivering the mail is: mail_spool_home: debug_print = "T: appendfile for $local_part@$domain" driver = appendfile file = /home/vmail/$domain/$local_part/INBOX delivery_date_add envelope_to_add return_path_add group = mail mode = 0660 mode_fail_narrower = false The problem is reproducable in that I see the problem occur everyday. I am about to compile and install rc28 to see if that improves matters. I'd appreciate any help resolving the problem! Here is my dovecot.conf: # /usr/local/etc/dovecot.conf protocols: pop3 imap imaps disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_extra_groups: mail mail_location: mbox:/home/vmail/%d/%n/mail/:INBOX=/home/vmail/%d/%n/INBOX mbox_dirty_syncs: no mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/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 auth default: passdb: driver: passwd-file args: /etc/vmail.passwd userdb: driver: static args: uid=1064 gid=1001 home=/home/vmail/%d/%u

[Dovecot] Bug-report for rc28: Mailbox isn't a valid mbox file
by Erik van Oosten 29 Mar '07

29 Mar '07

Hi, When I try to open the attached mbox file I get the following warning in Thunderbird 1.5.0.10: 'The current command failed. The e-mail server responded: Mailbox isn't a valid mbox file'. I also tried this with squirrelmail, with the same result. The Dovecot version is dovecot-1.0.rc28, compiled from source. The attached mbox was correctly read from, and written to in earlier versions (either rc15 or rc22, I am not sure). The initial import was done (a long time ago) by copying a file from my Thunderbird profile directory. OS: SuSE 10.0, x86 Filesystem: ext3, (no NFS) Output of dovecot -n: ------------------------------------ # /usr/local/etc/dovecot.conf disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u auth default: passdb: driver: pam userdb: driver: passwd ------------------------------------- Can I somehow recover the data in this mbox?

[Dovecot] odd behavior with Dovecot LDA
by Steven F Siirila 29 Mar '07

29 Mar '07

Okay, to convince myself that quota handling was working okay with Dovecot 1.0-rc27 on Solaris 10, I tested sending a message to an account that was purposely over-quota. The account in question had a vacation message set up. For the first test, there was no $HOME/.imap directory at all. I received the vacation message, but the message which was supposed to be delivered locally queued in Postfix (temporary failure). For the second test, I created $HOME/.imap and $HOME/.imap/INBOX directories with the owner and group set to that of the user (just to make sure the code handled things the same). Again, I received the vacation message, but the message which was supposed to be delivered locally bounced back to me after Dovecot LDA crashed: <syst0005(a)peridot.tc.umn.edu>: Command died with status 139: "/opt/dovecot/libexec/dovecot/deliver -f "$SENDER"". Command output: Segmentation Fault It appears that Dovecot LDA assumes that if .imap/FOLDERNAME exists that the index files must also exist.. I wonder what other assumptions might cause segfaults. -- Steven F.

[Dovecot] How do I check the release #?
by Randolph Kahle 29 Mar '07

29 Mar '07

I am a dovecot newbie and I am setting up a machine that already has dovecot installed. Since bugs are being resolved rapidly, it appears that I need to know the release version of dovecot I am running. Is there a command I can issue or a file I can examine to determine the release version of my installation? -- Randy

[Dovecot] transfer files from Plesk qmail to Dovecot and Postfix
by Frank Church 29 Mar '07

29 Mar '07

I have some files I want to transfer from Plesk qmail to Postfix with virtual mailboxes, MySQL, Maildir etc. I can add the accounts to the database manually as there are only a few of them. In the case of the mail folders, is it merely a matter of copying the mail files over, or are there some adjustments to be made to the files? I have noticed the thread about the Courier to Dovecot script and I wonder whether it may have a role in this process.

[Dovecot] auth server refusing connections intermittently
by Steven F Siirila 28 Mar '07

28 Mar '07

Running Dovecot 1.0-rc27 on Solaris 10.. We have been noticing intermittent messages of this sort and wondered if this indicates whether we need to add more dovecot-auth worker processes: Mar 28 03:15:41 myhost dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 28 08:10:20 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 09:08:13 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 10:23:38 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 10:35:37 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 10:50:59 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 12:00:44 myhost dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 28 12:07:31 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 14:44:57 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused However, this system has over 7,000 users and 1,500 simultaneous IMAP and POP3 connections, and we only see one dovecot-auth process running. By contrast, another server has over 11,000 users and 3,000 simultaneous IMAP and POP3 connections (but is currently running rc24), and we only have seen 3 of the above error messages there -- and there is only one dovecot-auth process there as well. Does this sound right? Also, how many times are these connections retried (and at what sleep interval, if any) before it gives up? -- Steven F.

[Dovecot] Removing users maildir DOVECOT+LDAP

Hi all, Does anyone have an idea how can I remove(delete) my virtual mail users' maildir? I have Dovecot + LDAP and I would like to do something like this: When I remove an user entry in my ldap server, it should remove my user directory information. Does anyone has this implemented? Or have an idea? I can remove users entry in my ldap server remotely, is there some way in dovecot? I'm asking this, cause I'm very familiar with Cyrus and I can do this with it.

[Dovecot] Deliverm, vpopmail, and valias
by John Peacock 28 Mar '07

28 Mar '07

I'm in the final stages of testing my e-mail server to come and I seem to have hit a roadblock. One option of current vpopmail is to store all aliases in a valias table, that looks like this: +-------------+----------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------+----------+------+-----+---------+-------+ | alias | char(32) | NO | MUL | | | | domain | char(64) | NO | | | | | valias_line | text | NO | | | | +-------------+----------+------+-----+---------+-------+ where valias_line could be either an e-mail address (preceded by an ampersand) or a command (piped to vacation for example). I have already accepted a message for an aliased address, but the MTA isn't going to be rewriting the envelope address, so how can I get dovecot's deliver to dereference the alias and deliver to the correct Inbox? Because of the number of other hops[1] that the message is going through, I don't want to rewrite the destination address unless I really have to, but if that is the only option, that is what I'll have to do. Thoughts? John 1) inbound e-mail hits a qpsmtpd instance which validates e-mails using several different filtering techniques. Next the mail gets fed to a dspam appliance running two Postfix queues (one before dspam and one after). Mail that isn't quarantine by dspam gets sent to the delivery server (currently running qmail) and delivered to the final destination (modulo sieve rules under deliver). The only place I could conceivably rewrite the address would be the second Postfix queue. -- John Peacock Director of Information Research and Technology Rowman & Littlefield Publishing Group 4501 Forbes Boulevard Suite H Lanham, MD 20706 301-459-3366 x.5010 fax 301-429-5748

[Dovecot] ignoring some subfolders [potential wishlist]
by Arkadiusz Miskiewicz 28 Mar '07

28 Mar '07

Hello I'm looking at migration path from my current setup (tpop3d/courier-imap) and I seem to miss one feature - ability to ignore some subfolders for pop3. tpop3d allows me to say: maildir-ignore-folders: Spam Trash trash Sent sent-mail POP3-Invisible (would be stupid to fetch own sent-mail via pop3 again 8-) In recent tpop3d cvs version I can also use regexps like maildir-ignore-folders: ^IMAP-Only.*$. Is it possible to ignore some subfolders in dovecot per protocol (like for pop3 only and not imap) ? If not then please consider this as wishlist, maybe in form of location negation like: mail_location = \ maildir:/var/mail/%Lu:!maildir:/var/mail/%Lu/.Something (which doesn't look sane) or with separate config directive like in tpop3d -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

Hello, I have a problem (at least with 1.0rc28 and 1.0rc27) when using the following namespace definitions: namespace private { separator = "/" inbox = yes location = mbox:~/Mail:INBOX=/var/spool/mail/%u } namespace public { separator = / prefix = 0-LISTS/ location = mbox:/var/mail/lists:INDEX=~/.sharedMail/lists/index } namespace private { separator = "/" prefix = "0-MAILDIR-FOLDERS/" location = maildir:~/Maildir } IMAP access is working as expected, but when connecting with POP3(s), the (mostly empty in our case) ~/Maildir is used as mail location when it has been created (including index files) by IMAP access. If ~/Maildir does not exist/has been deleted again, POP3 uses /var/spool/mail/%u. This is independent of the private namespace section order and also an explicit "inbox = no" in 0-MAILDIR-FOLDERS namespace. Any idea if this is an configuration issue I don't understand yet or a bug?

[Dovecot] Allow/disallow mail access based on group membership
by Taras Savchuk 28 Mar '07

28 Mar '07

I'm just finished FreeBSD/AD integration via Kerberos/LDAP and now I can manage unix users/groups from AD. I want to grant access to IMAP based on user membership in certain group. Is it possible? Can you give me some hints? Thanks in advance! -- С уважением, Савчук Тарас ООО "Элантек" : Аутсорсинг ИТ, WEB-разработка http://www.elantech.ru +7 (495) 589 68 81 +7 (926) 575 22 11

[Dovecot] LDAP group quota support
by Ioannis Zachariadis 28 Mar '07

28 Mar '07

Is there a plan to support LDAP group quotas in the future releases ? Just like the ldap quota plugin for users but with additional support for a unified quota for a group users. -- giannis.

[Dovecot] proxy host specified as fqdn in userdb
by Apostolos Papayanakis 28 Mar '07

28 Mar '07

Abstract from http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy > > host=s: The destination server's *IP address*. This field is required. > Note that currently it's required to use an IP address since no DNS > resolving is done. > Hello Timo, Here goes one more item for the v2.0 wishlist: Will it become possible to do dovecot imap proxying based on a "host" userdb attribute that is an FQDN (instead of a numeric IP as it is now)? It would simplify things for large smtp clusters that already do LDAP mail routing, based on per user "mailHost" attribute containg mail server FQDNs (according to "IETF Internet Draft LDAP Schema for Intranet Mail Routing", http://www.sendmail.org/m4/laser.txt) It is kinda redundunt to keep an extra LDAP attribute for "host" that contains essentially the same information as "mailHost" attribute, but in numeric form. I know the proposed change is not that important for many people, so don't really bother unless it is trivial to implement. apap

[Dovecot] rc2x seems to break Pegasus Mail
by Rick Romero 28 Mar '07

28 Mar '07

Hi guys, I upgraded from rc7 to rc24 a couple weeks ago, and noticed today that Pegasus Mail's IMAP no longer connects. So I put rc27 in, and it worked, but only for a little while... I'm not sure what the problem might be, the logs look fine, and I can still use Horde and Evolution without a problem. Pegasus Mail's error is unfortunately not helpful. Restarting rc27 didn't 'bring it back' for Pegasus. I turned on debugging, but I don't know what to look for because other clients work :/ dovecot: Mar 22 09:55:58 Info: imap-login: Login: user=<rick>, method=PLAIN, rip=172.16.100.20, lip=172.16.100.10, TLS dovecot: Mar 22 09:55:58 Info: IMAP(rick): Loading modules from directory: /usr/local/lib/dovecot/imap dovecot: Mar 22 09:55:58 Info: IMAP(rick): Module loaded: /usr/local/lib/dovecot/imap/lib10_quota_plugin.so dovecot: Mar 22 09:55:58 Info: IMAP(rick): Module loaded: /usr/local/lib/dovecot/imap/lib11_imap_quota_plugin.so dovecot: Mar 22 09:55:58 Info: IMAP(rick): Effective uid=89, gid=89, home=/usr/home/vpopmail/domains/havokmon.com/rick dovecot: Mar 22 09:55:58 Info: IMAP(rick): Namespace: type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, subscriptions=no dovecot: Mar 22 09:55:58 Info: IMAP(rick): maildir: root exists (/usr/home/vpopmail/domains/havokmon.com/rick/Maildir) dovecot: Mar 22 09:55:58 Info: IMAP(rick): maildir: root=/usr/home/vpopmail/domains/havokmon.com/rick/Maildir, index=/usr/home/vpopmail/domains/havokmon.com/rick/Maildir, control=, inbox= dovecot: Mar 22 09:56:03 Info: imap-login: Login: user=<rick>, method=PLAIN, rip=172.16.100.20, lip=172.16.100.10, TLS dovecot: Mar 22 09:56:03 Info: IMAP(rick): Loading modules from directory: /usr/local/lib/dovecot/imap dovecot: Mar 22 09:56:03 Info: IMAP(rick): Module loaded: /usr/local/lib/dovecot/imap/lib10_quota_plugin.so dovecot: Mar 22 09:56:03 Info: IMAP(rick): Module loaded: /usr/local/lib/dovecot/imap/lib11_imap_quota_plugin.so dovecot: Mar 22 09:56:03 Info: IMAP(rick): Effective uid=89, gid=89, home=/usr/home/vpopmail/domains/havokmon.com/rick dovecot: Mar 22 09:56:03 Info: IMAP(rick): Namespace: type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, subscriptions=no dovecot: Mar 22 09:56:03 Info: IMAP(rick): maildir: root exists (/usr/home/vpopmail/domains/havokmon.com/rick/Maildir) dovecot: Mar 22 09:56:03 Info: IMAP(rick): maildir: root=/usr/home/vpopmail/domains/havokmon.com/rick/Maildir, index=/usr/home/vpopmail/domains/havokmon.com/rick/Maildir, control=, inbox= dovecot: Mar 22 09:56:03 Info: IMAP(rick): Disconnected: Logged out Config: base_dir = /var/run/dovecot/ protocols = imap imaps listen = * disable_plaintext_auth = no shutdown_clients = yes log_path = /var/log/dovecot/dovecot.log info_log_path = /var/log/dovecot/dovecot_info.log log_timestamp = "%b %d %H:%M:%S " ssl_cert_file = /usr/local/share/courier-imap/mail-vfemail-godaddy.crt ssl_key_file = /usr/local/share/courier-imap/mail-vfemail-godaddy.key ssl_key_password = verbose_ssl = no login_dir = /var/run/dovecot/login login_user = nobody login_process_size = 64 login_process_per_connection = yes login_processes_count = 15 login_max_processes_count = 512 login_greeting = VFEmail IMAP Dovecot ready. namespace private { separator = . prefix = INBOX. inbox = yes } mail_debug = no mmap_disable = yes verbose_proctitle = yes first_valid_uid = 89 last_valid_uid = 0 protocol imap { mail_plugins = quota imap_quota imap_client_workarounds = outlook-idle } protocol pop3 { } protocol lda { postmaster_address = admin(a)vfemail.net } auth_verbose = no auth_debug = no auth default { mechanisms = plain passdb checkpassword { args = /usr/local/vpopmail/bin/vchkpw } userdb prefetch { } user = vpopmail } dict { } plugin { quota = maildir } I compiled both rc2x's with just ./configure Install prefix ...................... : /usr/local File offsets ........................ : 64bit I/O loop method ..................... : poll File change notification method ..... : none Building with SSL support ........... : yes (OpenSSL) Building with IPv6 support .......... : yes Building with pop3 server ........... : yes Building with mail delivery agent .. : yes Building with GSSAPI support ........ : no Building with user database modules . : static prefetch passwd passwd-file checkpassword vpopmail (modules) Building with password lookup modules : passwd passwd-file pam checkpassword vpopmail (modules) Building with SQL drivers ............: Though - for rc27, I had to disable vpopmail because it wouldn't build.

[Dovecot] rc29 and documentation changes
by Timo Sirainen 28 Mar '07

28 Mar '07

http://dovecot.org/nightly/dovecot-latest.tar.gz Any comments about the doc/wiki/ contents? doc/documentation.txt? dovecot-example.conf's doc/wiki/ pointers? ./autogen.sh now updates the wiki from http://www.dovecot.org/tmp/wiki-export.tar.gz (updated each night) if doc/wiki/Authentication.txt doesn't exist. I guess I'll release rc29 tomorrow. The current changes are: + Added auth_gssapi_hostname setting. - IMAP: LIST "" "" didn't return anything if there didn't exist a namespace with empty prefix. This broke some clients. - If Dovecot is tried to be started when it's already running, don't delete existing auth sockets and break the running Dovecot - If deliver failed too early it still returned exit code 89 instead of EX_TEMPFAIL. - deliver: INBOX fallbacking with -n parameter wasn't working. - passdb passwd and shadow couldn't be used as master or deny databases - IDLE: inotify didn't notice changes in mbox file - If index file directory couldn't be created, disable indexes instead of failing to open the mailbox. - Several other minor fixes

[Dovecot] MANAGESIEVE patch v3 for dovecot 1.0.rc28
by Stephan Bosch 28 Mar '07

28 Mar '07

Hello dovecot users, I have updated the MANAGESIEVE patch to apply and compile against dovecot 1.0.rc28. Not much has changed with respect to the functionality of the previous version however: ChangeLog vs v2 - Updated source to compile with dovecot 1.0.rc28, tested with rc27 (debian package) - Daemon now uses the same location for .dovecot.sieve as dovecot-lda This is typically ~/.dovecot.sieve. - If .dovecot.sieve is a regular file, it is now moved into the script storage as dovecot.orig.sieve, preventing deletion of (important) active scripts upon managesieve installation. Otherwise, it would simply be replaced by a symlink to the new active script. - Changed error handling to yield a BYE message when the managesieve daemon exits unexpectedly (upon login) before any commands are entered. Horde-ingo would wait indefinitely for a response. This patch still includes (yet another) instance of the CMU Sieve source, as explained in my previous mail (http://dovecot.org/list/dovecot/2006-July/015016.html) It can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.rc28-MANAGESIEVE-v3.diff.gz Have fun testing the patch. Notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] gssapi auth issue...
by Dan Price 28 Mar '07

28 Mar '07

Hi all-- been away from the list for a few weeks so forgive me if this problem has been reported-- with the help of some of our Kerberos engineers, we tracked down why we can't authenticate our Solaris kerberos clients to Dovecot. Here's the deal: Our IT organization issued us kerberos tickets of the form imap(a)foobar.sfbay.sun.com Which I presume is their standard-- and probably not negotiable. However, the hostname of the machine is: "foobar", not foobar.sfbay.sun.com (as reported by gethostname(3c)). So when dovecot does this: mech-gssapi.c: principal_name = t_str_new(128); str_append(principal_name, service_name); str_append_c(principal_name, '@'); ---> str_append(principal_name, my_hostname); We wind up asking kerberos to look for a ticket for imap@foobar, instead of imap(a)foobar.sfbay.sun.com. Obviously we can patch the source, but I was wondering if we could have a gssapi_hostname setting in the config file? Or perhaps we could have a knob letting us globally override my_hostname? Although I don't know what side effects that could have. We have some new cores I also need to report-- I'll get on that. Thanks in advance, -dp -- Daniel Price - Solaris Kernel Engineering - dp(a)eng.sun.com - blogs.sun.com/dp

[Dovecot] Custom Mail Directory for some users
by Patrick Kranz 27 Mar '07

27 Mar '07

Hi list, I'm new on this mailing list and I'm kind of stucked at the moment. I managed to get Postfix and Dovecot working together with Amavis, OpenLDAP und SASL on Ubuntu Linux Release "Dapper Drake". The Dovecot version shipped with Dapper is 1.0-beta3 (at least, that's what the package database tells me), I also tried this with a Debian Backport of version 1.0-rc15. And here is my problem: A customer of mine needs usernames different from the mail address for his third party software to work. In other words, I need the ability to login with the username foo to get access to the mailbox bar(a)example.com. So I tried to override the mail_location property for this user with a separate mailDirectory attribute in my LDAP tree. Speaking in dovecot.conf words: mail_location = maildir:/var/spool/dovecot/mail/%d/%n auth default { machanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.com } userdb ldap { args = /etc/dovecot/dovecot-ldap.com } userdb static { args = uid=vmail gid=vmail user = dovecot } and dovecot-ldap.conf: hosts = localhost dn = cn=admin,dc=ekits,dc=de dnpass = secret auth_bind = yes ldap_version = 3 base = ou=mailsystem,dc=ekits,dc=de scope = subtree user_attrs = mailDirectory=mail user_filter = (&(objectClass=ekitsMailAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=ekitsMailAccount)(uid=%u)) user_global_uid = vmail user_global_gid = vmail a typical ldap entry looks something like this: dn: cn=Patrick Kranz,o=EK IT-Solutions,ou=mailsystem,dc=ekits,dc=de ekitsMailDestination: patrick(a)ekits.de objectClass: ekitsMailAccount objectClass: top cn: Patrick Kranz structuralObjectClass: ekitsMailAccount entryUUID: b4ebb9e8-6d8d-102b-9dc9-9edb870845a4 creatorsName: cn=admin,dc=ekits,dc=de createTimestamp: 20070323132526Z userPassword:: YVBhc3M= mailDirectory: maildir:/var/spool/dovecot/mail/ekits.de/blubb uid: patrick As far as I can interpret the log of slapd, dovecot doesn't even ask for the attribute "mailDirectory". I also tried this with userdb prefetch. With this it did actually ask for the attribute but it still had no effect. With this configuration dovecot creates the directory /var/spool/spool/dovecot/mail/patrick if I login with the uid patrick but I wanted access to /var/spool/dovecot/mail/ekits.de/blubb If anybody has any clue what I did wrong or if I have a conceptional misunderstanding, I would appreciate every help. Thanks in advance. Greetings, Patrick

[Dovecot] Sync of read message status between squirrelmail and outlook express
by Mohd Ikhwan Abdullah 27 Mar '07

27 Mar '07

Hi, We have a Linux email server running CentOS 4.4. I have a scenario here. The users here use a mixture of outlook express and squirrel mail as their email client. The users download their mail into outlook express via pop3 but the have configured outlook express to leave a copy on the server for 7 days. 1. After downloading the mail into outlook express the users would read the mail and the mail would be set as 'READ' in outlook express. 2. Is there a way to configure dovecot so that the 'READ' status in outlook express is reflected on the message still stored on the server as well. Cause when they access via squirrel mail the message is still mark as 'UNREAD'. Any suggestions is very much appreciated. Thanks in advance.

[Dovecot] LDA bouncing mails after upgrade
by Milan Holzäpfel 27 Mar '07

27 Mar '07

Hello, on my system, I have a copy of /usr/libexec/dovecot/deliver located in /usr/libexec/dovecot/postfix-deliver/deliver (only accessible to postfix and with SUID root permissions). If I happen to forget to update this copy after an upgrade of dovecot, the deliver LDA bounces mails: | Mar 22 20:29:20 host.example.org deliver(user(a)example.org): Module is for different version 1.0.rc27: /usr/lib/dovecot/lda/lib10_quota_plugin.so | Mar 22 20:29:20 host.example.org postfix/pipe[17344]: <ID>: to=<user(a)example.org>, relay=dovecot, delay=1.9, delays=1.5/0/0/0.35, dsn=5.3.0, status=bounced (Command died with status 89: "/usr/libexec/dovecot/postfix-deliver/deliver") Should I just set version_ignore=yes and remember myself to upgrade it, or could deliver return a code signaling "temporary failure", or should I rather make postfix interpret 89 as temporary failure? (don't know by heart whether that's possible). Regards, Milan -- Milan Holzaepfel <mail(a)mjh(d)name> <URL:http://mjh.name/> pub 4096R/C790FC23 EB8E 5E81 81E3 53A9 9B74 B895 5179 54C0 C790 FC23

[Dovecot] netapp/maildir/dovecot performance
by bofh list 26 Mar '07

26 Mar '07

We are seeing some poor performance recently that is focused around users with large mailboxes (100,000 message /INBOX, 80,000 message subfolders, etc). The performance problem manifests as very high system% utilization - basically iowait for NFS. There are two imap servers with plenty of horsepower/memory/etc. They are connected to a 3050c cluster via gig-e. Here are the mount options: rw,tcp,nfsvers=3,rsize=8192,wsize=8192,nosuid,nodev,soft,intr,noac,actimeo=0 I need to get this system% utilization brought down because it is starting to slowdown imap performance for other users (it goes up to 95% on a regular basis, with users that have folders with many messages). My thought is to try removing the noac option and bump up the actimeo value from 0 to 30. Unfortunately I don't have access to use a SLB to direct traffic to individual servers. My understanding is that the worst that can happen is index corruption (which will result in rebuilding them when it happens). Any thoughts? I'm running RC24.

[Dovecot] Unwanted INBOX. prefix issues
by Kevin Bowling 26 Mar '07

26 Mar '07

I have a strange problem. I installed Dovecot and had my trash folder and such in the root of my maildir, and everything was working great. I then installed SquirrelMail which created folders in with the INBOX. prefix. I manually removed these from the maildir, but the INBOX.Trash is still shown in the folder listing of Thunderbird. This leads to some strange behavior, such as the delete button not working. Is there a way I can reset the folder list, and take the INBOX.* items out? Any help would be appreciated. Regards, Kevin

[Dovecot] Rpm builders: Dovecot spec file
by Egbert Jan 26 Mar '07

26 Mar '07

Maybe best asked to Axel... I'm re-building my server from scratch (the old one was MDK 10.1 -> Mandriva 2006.0 with Postfix/Courier) and I want to install the latest versions postfix/mysql/postfixadmin/dovecot/squirrelmail. I've been building Dovecot (and postfix) from tarballs/srpm in the past so I know more or less how it all fits together. But I wonder if 'old' patches still need to be included/applied in the building of the latest rc's. I still see references to those patches in the spec file. Unfortunately the latest 'official' rpm for Mandriva (I'm running 2007.0) is rc7 and I never succeeded getting in contact with the Mandriva maintainer to ask the same question. In the Axel's AT rpm I still see some patches included but others than in the Mandriva rc7 spec file. Are those patches not already applied to the latest sources by Timo? Tnx Egbert Jan NL

[Dovecot] Bug tracking system
by Timo Sirainen 26 Mar '07

26 Mar '07

There are three reasons why I haven't really bothered setting up a bug tracking system for Dovecot: 1) They're all kind of annoying to use. 2) They all require a lot of stuff like PHP, SQL server, etc. which I don't really want to put into dovecot.org. 3) Probably most importantly: If people start reporing bugs in there, I'm pretty much the only person who will ever read them and reply to them. Currently when people report bugs in here, it's quite useful to have other people read them too. They may already know the bug and say they've reported it, they may have an idea what's causing it, they may know a workaround, etc. All in all, moving things to BTS would most likely cause my life to be harder and it might be more difficult to get some bugs fixed. A couple of days ago I started thinking about this and then I figured out a way to solve all of this nicely with a new and great Dovecot based bug tracking system. :) Just so I won't forget it, here's the plan: Dovecot BTS ----------- The preferred way to report bugs is to send them to dovecot-bugs(a)dovecot.org. The only thing it does is prefix the subject line with [BUG #nnn] and forward it to dovecot(a)dovecot.org. Now everyone can reply to it just as it was a normal mailing list mail. As long the subject contains the "[BUG #nnn]" prefix, it's part of the bug. Existing mailing list threads can also be turned into bugs by replying to the thread's root message with To: dovecot-bugs(a)dovecot.org. This again causes the new reply to contain [BUG #nnn] prefix. Then comes the web part. There's no SQL database or anything, everything is stored in a mailbox in the IMAP server. The mailbox contains the whole dovecot(a)dovecot.org archive. Bug metadata such as priority, status, etc. is stored using IMAP ANNOTATE extension, which allows setting key=value pairs to messages. Unfortunately Dovecot doesn't yet support that extension. Bugs' root messages contain the annotations for the whole bug thread. So to get a list of all bugs, the BTS issues an IMAP SEARCH ANNOTATE command to list all messages with some specific "bug=yes" type of annotation. For those messages then it can fetch the subject and whatever else metadata it wants. Newly created bugs don't have annotations though. To fix that, the BTS also uses ANNOTATEMORE (or is it METADATA nowadays?) extension to keep "last seen message in BTS" state in the mailbox's annotations. It then issues a SEARCH SUBJECT "[bug #" command for the new messages and does THREAD command for them to see if they're the bug root, or if they were replies to another message which should be treated as the bug root. When viewing a bug, the bug metadata comes from the annotations. Annotation history could also be kept, possibly as messages in another history mailbox. The messages for a bug can be viewed by issuing a THREAD (REFERENCES) command and showing all the mails that exist under the bug root. So, any volunteers to implement the web part, if I implement the ANNOTATE extension? :) It would actually even be possible to implement multiple frontends. All I need to do is give you access (read-only, or read-write for some) to the bug tracking mailbox, and you can use whatever frontend you wish, even a non-web one!

[Dovecot] Dovecot LDA issues
by Steven F Siirila 26 Mar '07

26 Mar '07

We've seen two issues come up with Dovecot LDA, both of which have caused us problems: 1) If the user's home directory does not exist, or is not owned by them, deliver fails and causes the mail message to bounce back to the originator. In our environment this happens when our user is moved to another server (where we move their files, but for up to 24 hours afterwards, continue to re-mail their /var/mail INBOX). This no longer works because the user has no home directory, causing deliver to fail with "Permission denied" when attempting to create their home directory for the purposes of creating INBOX index files. 2) If the user is over quota (in their home directory), deliver fails with a temporary error, causing requeues until the user is back under quota (which in our environment could be a long time, days). Since we've never had quotas on the user's INBOX (in /var/mail), this is a problem for us. I'd propose for both of these cases that deliver issue WARNING messages to its logs, and simply not create index files for the INBOX. If the INBOX index files already exist, and the user is over quota in /home, neither deliver nor any other Dovecot process should attempt to update them, and instead issue WARNING messages. This allows the e-mail to be delivered instead of requeued, or worse yet, rejected. Index files are supposed to make things perform better, not worse, in ALL cases. :) -- Steven F.

[Dovecot] deliver: -m, sieve and -n
by Jim Horner 26 Mar '07

26 Mar '07

Hi, I took a stab at editing the wiki ... the changes disappeared? I guess I was overruled. The wiki (http://wiki.dovecot.org/LDA) states -m <mailbox>: Destination mailbox (default is INBOX). If the mailbox doesn't exist, it's created (unless -n is used). If message couldn't be saved to the mailbox for any reason, it's delivered to INBOX instead. I tried to add a little note that the sieve plugin takes precedence. For example if at the end of the a .dovecot.sieve there is a line like: fileinto "CompanyFolders.general"; then the -m <mailbox> is ignored. I am not sure about the use of 'stop'. -n: If the destination mailbox doesn't exist, don't create it. This affects both -m parameter and fileinfo action in Sieve scripts. The fallback is to deliver mail to INBOX. (typo: fileinto not fileinfo) My testing shows that if the mailbox does not exist then the mail is rejected like so: === Your message was automatically rejected by Dovecot Mail Delivery Agent. The following reason was given: Mailbox doesn't exist: mail-lists.debian === I like the wiki's solution better. Jim

[Dovecot] dovecot authentication & exim in rc27
by Richard P. Welty 26 Mar '07

26 Mar '07

[introduction: new to the list, used dovecot w/exim as MTA in simple ways for 2 years, blah blah blah] i'm trying to get exim to use dovecot auth with a copy of rc27 and am missing something that's probably quite simple. specifically, how does one configure the authenticators in dovecot.conf for rc27? the auth section of the default config file installed in rc27 doesn't entirely look like what i'm seeing in other documentation; instead of auth default { } i'm seeing auth = default followed by lots of standard flags prefixed by auth_, but i don't see how to set up the socket. i have the following; dovecot starts and doesn't complain but it doesn't create the socket either: auth_socket listen { client { path = /var/run/dovecot/auth-client mode = 0660 user = exim group = exim } } any suggestions? thanks, richard

[Dovecot] anonymous mailing list archive configuration?
by Johannes Berg 25 Mar '07

25 Mar '07

Hi, I'd like to run a mailing list archive via IMAP like for this list but my mails are in maildir and not mbox. It's easy to add a new user that has access to the maildir that mails get stored in, and I can simply link that up to that user's inbox. It's also easy to prevent putting mail into that folder. However, one thing I'm not clear on is how to prevent that user from creating new folders. I don't think I can do that with permissions to the ~/Maildir since that user needs to be able to create files there for indizes etc. Is that possible? Should/can I write a plugin that prevents things? johannes

[Dovecot] 1.0.rc28 / v1.0 plans
by Timo Sirainen 24 Mar '07

24 Mar '07

I'll probably release 1.0.rc28 in a few days. Would be nice to get some testing for it first. http://dovecot.org/nightly/dovecot-latest.tar.gz contains pretty much what it's supposed to be. I've now replied to all the mails I was planning on replying, excluding the few patches that are v1.1 material. If you think I forgot to reply to some mail, please resend it. I think the documentation in Wiki is finally beginning to look pretty good. All the important things are done. The only things in my "would be nice TODO" list are: - Add a new page about index files and their configuration. I'll probably do this before rc28. - PasswordSchemes and Authentication/Mechanisms are pretty heavy reading. Could be made easier to understand. Possibly also create some mechanism-specific pages describing how to configure them in Dovecot and in clients. - Design documents would also be nice, but not very useful for non-programmers and pretty big job to write them I'm planning on adding the Wiki pages to doc/wiki/ in the tarball and changing: - http://wiki.dovecot.org/* links to doc/wiki/*.txt in dovecot-example.conf - doc/variables.txt could be removed and links to it updated to doc/wiki/Variables.txt - doc/auth-protocol.txt is also already in wiki. Maybe create doc/design/ and put the AuthProtocol.txt there and other design wiki pages there as well. As for v1.0, it looks like there aren't many bug reports anymore about rc27. If there are as few for rc28, I'll release v1.0 in about a month. So unless something special happens, I'll fix only the simplest bugs after rc28 and leave the rest to v1.1/v1.0.1. Hmm. Looks like 13.4. is Friday. Perhaps that's a good day for a release. :) Looks like I ended up adding a few more new features to rc28: * deliver + userdb static: Verify the user's existence from passdb, unless allow_all_users=yes * dovecot --exec-mail: Log to configured log files instead of stderr + When copying/syncing a lot of mails, send "* OK Hang in there" replies to client every 15 seconds so it doesn't just timeout the connection. + Added idxview and logview utilities to examine Dovecot's index files + passdb passwd and shadow support blocking=yes setting now also + mbox: If mbox file changes unexpectedly while we're writing to it, log an error. + deliver: Ignore -m "" parameter to make calling it easier. + deliver: Added new -n parameter to disable autocreating mailboxes. It affects both -m parameter and Sieve plugin's fileinto action - auth cache: If unknown user was found from cache, we didn't properly return "unknown user" status, which could have caused problems in deliver. - Index view syncing fixes - rc27 didn't compile with some non-GCC compilers - vpopmail support didn't compile in rc27 - NFS check with chrooting broke home direcotry for the first login - deliver: If user lookup returned "unknown user", it logged "BUG: Unexpected input" - convert plugin didn't convert INBOX

[Dovecot] Dovecot LDA Logging

I have Dovecot LDA logging fine right now but I really don't like having my log files world writable because I have users with shell access.

[Dovecot] multiple instances of dovecot on one machine
by Marshal Newrock 23 Mar '07

23 Mar '07

I was trying to run two instances of dovecot on the same machine, each listening on a single IP. The problem I ran into was that each time one was started or restarted, the other stopped responding. I saw the following in the logs: Mar 23 00:02:27 sentinel dovecot: Dovecot v1.0.rc27 starting up Mar 23 00:02:27 sentinel dovecot: Socket already exists: /var/run/dovecot/dict-server After I saw that, I commented out the dict section and quota from the plugins. The second line disappeared, but I could still only get one dovecot listening at a time. In the end, I went back to a single dovecot listening on all IP's, and found another way to do what I was trying to do, so all is still working for me. I'm guessing I'm the first person to try to run two dovecots on one machine. Actually, I should clarify: there was also a third, listening to none on localhost, but there only for the lda process. The auth socket was set to /var/run/dovecot/auth-master. And this also was not accepting connections while the others were running. -- Marshal Newrock Ideal Solution, LLC - http://www.idealso.com

[Dovecot] Possible bug with removing e-mail when user over fs quota
by Qweb - Yavuz Aydin 23 Mar '07

23 Mar '07

Dear list, I don't know if this is by design or possibly a bug, but there is a difference when removing e-mail when a user is over filesystem quota when indexing is on or off. All is working fine on our servers when indexing is on, users can remove then purge e-mail when over quota, but when we turn off indexing (by setting INDEX=MEMORY) it doesn't work. Users can remove, but not purge. And after a reload of the page the e-mail is there again. We are using Dovecot 1.0.rc15 on Debian Sarge (through backports.org) with mboxes. We have set up the configuration of dovecot regarding quota's according to http://wiki.dovecot.org/Quota/FS Unfortunately I don't have time to try this on the latest version, but is there anyone out there willing to try? -- Best regards, Yavuz Aydin Qweb Internet Services

[Dovecot] maildirsize problem?
by Alan Mosca [Aluminati] 23 Mar '07

23 Mar '07

Hello all, Recently I have received a few complaints from users that their quota was being reported wrong. This seems to have started when I switched to quota=maildir and ignore=Trash (did both at the same time). The main reported problem is that maildirsize is not correctly updated when they delete messages. My personal hypothesis is something like this: - User moves to Trash - Trash is ignored so it is not marked on the maildirsize (?) - User purges trash - Trash is still ignored so it is still not marked (?) Resulting in a buildup of errors in the maildirsize file. Would it be a good idea to mark the maildirsize file when a file is moved to an ignored folder? That could though potentially lead to people just moving to trash instead of deleting. Thank you guys and keep up the good work! -- Alan Mosca Systems Administrator Aluminati Network Group

[Dovecot] Timeout while logging in

Hi, sometimes there is a timeout, while logging in. Dovecot-rc24 Dovecot uses PAM, PAM uses a LDAP server. Solaris 10 The log, if everything is ok: auth(default): client in: AUTH 1 PLAIN service=POP3 secured lip=x.x.x.x rip=x.x.x.x resp= auth(default): client out: CONT 1 auth(default): client in: CONT<hidden> auth(default): client out: OK 1 user=ssal0041 auth(default): master in: REQUEST 453 4779 1 auth(default): master out: USER 453 ssal0041 system_user=ssal0041 uid=3092 gid=1100 home=/home/ss pop3-login: Login: user=<ssal0041>, method=PLAIN, rip=x.x.x.x, lip=x.x.x.x, TLS POP3(ssal0041): Effective uid=3092, gid=1100 POP3(ssal0041): mbox: data=/home/ssal0041/mail/:INBOX=/var/mail/ssal0041 POP3(ssal0041): mbox: root=/home/ssal0041/mail, index=/home/ssal0041/mail, inbox=/var/mail/ssal0041 POP3(ssal0041): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 The log, if a timeout occures: auth(default): client in: AUTH 1 PLAIN service=POP3 secured lip=x.x.x.x rip=x.x.x.x resp= auth(default): client out: CONT 1 auth(default): client in: CONT<hidden> auth(default): client out: OK 1 user=ssal0041 auth(default): master in: REQUEST 454 4770 1 auth(default): master out: USER 454 ssal0041 system_user=ssal0041 uid=3092 gid=1100 home=/home/ss pop3-login: Login: user=<ssal0041>, method=PLAIN, rip=x.x.x.x, lip=x.x.x.x, TLS The rest is missing.

Re: [Dovecot] deliver to subfolder with dovecot's LDA
by Bill Boebel 23 Mar '07

On Fri, March 16, 2007 8:12 pm, Tom Bombadil <grlists(a)gmail.com> said: > How can deliver messages to a subfolder using the LDA? > For example, I want a message to joe+spam(a)abc.com to be placed inside > the 'spam' subfolder. $ deliver --help Usage: deliver [-c <config file>] [-d <destination user>] [-m <mailbox>] [-f <envelope sender>] So for the example above, you can call it like this: $ deliver -d joe(a)abc.com -m spam To do this from Postfix, /etc/postfix/master.cf: dovecot unix - n n - - pipe flags=DRhu user=virtual argv=/usr/libexec/dovecot/deliver -d ${recipient} -f ${sender} -m ${extension} However, I think LDA freaks out if you pass -m "". So this might not work when there is no "+folder". Timo: Should -m treat empty string as if -m was not passed at all? Bill
