[Dovecot] [ rc28 ] dict{} seems to be ignored
by Emiliano Gabrielli (aka AlberT) 06 Apr '07

06 Apr '07

Hi all, I'm new to the list, so ... hello everybody :-) Let's go to the point... I'm implementing quota over imap support in my mail server, so since a number of days I'm tring to upgrade to the new 1.x version (debian sarge) ... After having a number of troubles using the debian backport packege I am now using the -rc28 package that I have built by myself... I installed libmysqlclient14 and compiled dovecot with the following configure options: ./configure --with-ssl=openssl \ --with-mysql \ --disable-ipv6 \ --with-cyrus-sasl2 \ --with-gssapi \ --with-deliver \ --host=$(DEB_HOST_GNU_TYPE) \ --build=$(DEB_BUILD_GNU_TYPE) \ --prefix=/usr \ --sysconfdir=/etc/dovecot \ --libexecdir=\$${prefix}/lib \ --localstatedir=/var \ --mandir=\$${prefix}/share/man \ --infodir=\$${prefix}/share/info \ --with-moduledir=\$${prefix}/lib/dovecot/modules as taken from the sarge-backports debian package and after having removed pgsql, ldap and ipv6 support, as I don't need them... The imap over quota seem to work perfectly, since I can see quota info in IMAP clients (and via telnet) the only thing I can't make work is the dict: storage for quota info!! It seems the dict{ .. } section in the dovecot.conf file is *totally* ignored: dict { quotadict = mysq:/etc/dovecot/dovecot-dict-quota.conf } As you can see I have a typo in the driver name, but no error nor error message is given ... I followed the wiki instruction about Quota/Dict and I have created the necessary table ... that is not filled of course .. Anybody can tell me if may be a compilation problem, a configuration one or a bug in the current dovecot release ??

[Dovecot] Mailbox isn't a valid mbox file
by Jay Chandler 06 Apr '07

06 Apr '07

Keep getting this error within Squirrelmail (and other clients) on one particular user's mailbox file: ERROR: Could not complete request. Query: SELECT "INBOX.Backup" Reason Given: Mailbox isn't a valid mbox file I've snipped the first and last message off of it, still no love. mailserver# cat FILE | od -c | less 0000000 F r o m p r o m o t i o n s @ 0000020 e m e s s a g e . c i s c o . c So apparently there isn't a control character in the first message that'd be causing this either. Anyone have any ideas? Only one user out of many is having this issue, but he's whiny... -- Jay Chandler Network Administrator Chapman University

[Dovecot] Problems using GFS2 and clustered dovecot
by David Craigon 06 Apr '07

06 Apr '07

I am trying to use dovecot. I've got a GFS2 shared volume on two servers with dovecot running on both. On one server at a time, it works. The test I am trying is to attach two mail programs (MUA) via IMAPS (Thunderbird and Evolution as it happens). I've attached one mail program to each IMAPS server. I am trying to move emails around in one program (from folder to folder), and then checking it on the other program. I'm testing in effect how it would work if my users log on twice and end up on different servers. I seem to suffer from never ending index file corruption: Apr 4 16:55:49 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): Corrupted transaction log file /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex.log: end_offset (284) > current sync_offset (104) Apr 4 16:55:49 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): broken sync positions in index file /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex Apr 4 16:55:49 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): fscking index file /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex Apr 4 16:55:49 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): Fixed index file /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex: log file sync pos 1,284 -> 1, 104 Apr 4 16:55:50 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): Unexpected transaction log desync with index /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex Apr 4 16:56:18 mailstore-b dovecot: IMAP(david(a)everybody-loves.craigon.co.uk): Transaction log file /mnt/mailstore/e/everybody-loves.craigon.co.uk/d/david/.fish/dovecot.ind ex.log: marked corrupted This happens pretty quickly. I can also get message duplication- if I move a message from one server to another, I can get a message in the original folder and the destination folder. I am using RC28. I have tried using fcntl locking and dotlocking with equal lack of success. Can anyone offer any advice?

[Dovecot] managesieve proxy
by Marshal Newrock 06 Apr '07

06 Apr '07

We have dovecot on a pop/imap server working as a proxy to dovecot on the backend storage servers. This is working fine, but the difficulty is that if I use, for example, avelsieve in squirrelmail, it doesn't know where to connect. I imagine the same problem would exist with sieve-capable mail clients such as KMail, especially since the outside world isn't allowed to connect directly to the storage servers. Does anyone know of a way to proxy managesieve? -- Marshal Newrock Ideal Solution, LLC - http://www.idealso.com

[Dovecot] truncated maildir root?

Hello, I have successfully configure dovecot to lookup my existing user database to lookup the homedir.

[Dovecot] GSS/Kerb5, Solaris 10, how to build?
by Jeff A. Earickson 06 Apr '07

06 Apr '07

Gang, I've been trying to build rc29 under Solaris 10 using either "--with-gssapi" or Kerberos 5 ticket usage. I'm trying to figure out how to set up fetchmail on another S10 box to do IMAP fetches from dovecot without having to enter a password. No matter what configure option I try, I get Building with GSSAPI support ........ : no at the end of the configure. I searched the list archives and I see some discussion from Dan Price about Solaris 11 builds. Is gssapi supposed to work with Solaris 10? Advice please? My dovecot server is a Kerberos 5 client of Active Directory, with PAM configured to do TGT exchanges. I can login to the system with my AD password, ssh to other Kerb clients without having to type in passwords -- Kerberos works at the OS level. Jeff Earickson Colby College

[Dovecot] changing fs separator for maildir (suggestions?)
by Justin McAleer 05 Apr '07

05 Apr '07

Since we're migrating from an existing system that allows periods in folder names, I believe we must continue to allow them. So, I am deciding what to use as the separator instead. Right now, I'm leaning towards the backtick (`), since I don't think I have ever used it unless I was trying to execute an external command in some code. So, can anybody think of reasons not to use it, or have a better idea?

Re: [Dovecot] Problems using GFS2 and clustered dovecot
by David Craigon 05 Apr '07

05 Apr '07

Well, I'm not paying for it. And I've managed to fix the comedy stability I've come across so far, but you're right- I haven't really loaded the system up yet. My rationale is that I want a filesystem I can share between several servers, reducing the points of failure as far as I can down. We've got a large iSCSI SAN we've already bought for other projects, and I'd like to use that for our storage. So using NFS, I'd have to have another server in front of my SAN that act as an NFS server (presuambly as a single point of failuire), and the mail servers as NFS clients. I'd rather have the servers talk to the SAN directly. Besides, NFS never really works for me, but I'm sure I could overcome that. Anyway, I don't think it's a GFS problem so far.

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] 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

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] who owns dovecot files and dirs?
by Stewart Dean 01 Apr '07

01 Apr '07

...and what permissions should they have. I am thinking of /var/run/dovecot and the index directory. What ownership, group and permissions should they be? Are there any other files/dirs created for dovecot alone (not the mail folders and INBOXes); if so, how should they be owned and permed? I had thought they were to be owned by dovecot, but it turns out that they should not -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] 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

[Dovecot] Version Numbering and releases
by Peter Lindgren 31 Mar '07

31 Mar '07

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] 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
by Michal Soltys 29 Mar '07

29 Mar '07

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:

[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?

[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
by Venilton Junior 28 Mar '07

28 Mar '07

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/

[Dovecot] problem with POP3 mail location when using namespaces
by Lutz Preßler 28 Mar '07

28 Mar '07

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?

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

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?

[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

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] assertion failure with nopassword
by Johannes Berg 26 Mar '07

26 Mar '07

Hm, so my mailing list archive is up, but when I add nopassword to the list of settings in my passdb passwd-file I get: file auth-request.c: line 924 (auth_request_set_field): assertion failed: (request->passdb_password == NULL) Raw backtrace: dovecot-auth [0x806be11] -> dovecot-auth [0x806bd8c] -> dovecot-auth(auth_request_set_field+0x277) [0x80547d7] -> dovecot-auth [0x8060418] -> dovecot-auth [0x8060509] -> dovecot-auth(auth_request_verify_plain+0xb3) [0x80559b3] -> dovecot-auth [0x8055ac2] -> dovecot-auth(auth_request_verify_plain_callback+0x30) [0x8055b50] -> dovecot-auth [0x8060dbe] -> dovecot-auth(io_loop_handler_run+0x152) [0x806f1c2] -> dovecot-auth(io_loop_run+0x28) [0x806e508] -> dovecot-auth(main+0x2fb) [0x805aaab] -> /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xc8) [0xb7a3fea8] -> dovecot-auth [0x8050ff1] This is with rc27.

[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] Design docs in wiki

[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
by Jonathan Stewart 23 Mar '07

23 Mar '07

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. Is there a way to have Dovecot LDA log to syslog or would it be possible to write a mini-daemon that could log to syslog on behalf of Deliver or something else altogether? Jonathan

[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

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
by Kevin Richter 23 Mar '07

23 Mar '07

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

[Dovecot] I wrote a managesieve server for Dovecot
by Neale Pickett 22 Mar '07

22 Mar '07

I have written a managesieve server from scratch in Python. I did just enough work to get it working with avelsieve (the squirrelmail plugin), smartsieve, and KDE's sieve kioplugin. It supports the entire Internet draft. Since I didn't have a working sieve server to compare against, I'm not sure if it's 100% compatible with timsieved. Client applications seem to work okay anyway. I wrote it in such a way as to decouple how authentication is carried out and how sieve scripts are actually stored, so you could for instance modify this to work with SASL and Exim. Currently it only has code for PAM and Dovecot's LDA, because I run Postfix :). TLS support is in the code but disabled because I had problems writing a unit test for it. All my connections are from localhost anyway. http://woozle.org/~neale/repos/pysieved if anyone is interested. I haven't looked closely at Stephan Bosch's managesieve server in C but I do want to acknowledge that he has written a C managesieve server that currently exists as a patch to the Dovecot source code. People looking for a managesieve implementation in C are encouraged to try his patch out: http://sinas.rename-it.nl/~sirius/ Neale

[Dovecot] tilde in mbox:, when used in non-system user db
by Michal Soltys 22 Mar '07

22 Mar '07

Originally I've thought that this is related to INBOX field, but it turned out it happens only when you specify mbox. Consider following passwd-file: testms::10000:10000:imap,,,:/home/vmail/ppgk.com.pl/testms/./::userdb_mail=mbox:~/Mail:INBOX=/home/vmail/ppgk.com.pl/%u/inbox or following line from userdb static: args = uid=10000 gid=10000 home=/home/vmail/ppgk.com.pl/%u/./ mail=mbox:~/Mail:INBOX=/home/vmail/ppgk.com.pl/%u/inbox In both cases, in user's directory, there will be an empty ~/Mail directory created, in addition to Mail and inbox. No idea about how sql or ldap would behave here, but global mail_location from dovecot.conf doesn't suffer from this issue (~ was expanded properly in ktrace dump). Chroot specification (/./) doesn't matter here. If I change mbox:~/Mail:INBOX=..... to mbox:/home/vmail/ppgk.com.pl/%u/Mail:INBOX=~/inbox then everything will be fine - no extra '~' dir. Thus my assumption it's not INBOX field related. Looking at ktrace, it seems that imap process is checking for the existence of ~/Mail, without expanding tilde. Then quite a bit later, it creates Mail as a "side effect" of creating Trash subdirectory. Relevant fragments: 1853 imap CALL mkdir(0x8a79b100,0x1f8) 1853 imap NAMI "~/Mail" 1853 imap RET mkdir -1 errno 2 No such file or directory 1853 imap CALL sigprocmask(0x1,0xffffffff) 1853 imap RET sigprocmask 0 1853 imap CALL mprotect(0x3c0ec000,0x1000,0x3) 1853 imap RET mprotect 0 1853 imap CALL mprotect(0x3c0ec000,0x1000,0x1) 1853 imap RET mprotect 0 1853 imap CALL sigprocmask(0x3,0) 1853 imap RET sigprocmask -65793/0xfffefeff 1853 imap CALL mkdir(0x8a79b108,0x1f8) 1853 imap NAMI "~" 1853 imap RET mkdir 0 1853 imap CALL mkdir(0x8a79b100,0x1f8) 1853 imap NAMI "~/Mail" 1853 imap RET mkdir 0 and 1853 imap CALL stat(0x8a79b180,0xcfbeb5c0) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail/Trash" 1853 imap RET stat -1 errno 2 No such file or directory 1853 imap CALL stat(0x8a79b1b0,0xcfbeb600) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail/Trash" 1853 imap RET stat -1 errno 2 No such file or directory 1853 imap CALL mkdir(0x8a79b1e0,0x1f8) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail" 1853 imap RET mkdir 0 1853 imap CALL open(0x8a79b1b0,0xa02,0x1b0) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail/Trash" 1853 imap RET open 7 My configuration is prtty much the same as previously: openbsd 3.9, i386, dovecot 1.0-rc27 (latest nightly, but the same happened in stock 1.0rc27) dovecot.userdb: testms::10000:10000:imap,,,:/home/vmail/ppgk.com.pl/testms/./::userdb_mail=mbox:~/Mail:INBOX=/home/vmail/ppgk.com.pl/%u/inbox dovecot.passdb: testms:{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:

It is posible in the paper, in the real world? Hi Oliver, We run sendmail + dovecot on FreeBSD for around 3500 users. It runs smooth. We also run two other FreeBSD machines with Sophos PureMessage for Anti-SPAM and Anti-Virus cleanup which is linked via sendmail's milter. You're going to need Procmail to link sendmail and dovecot for local mail delivery to the user's mbox or Maildir, which ever you prefer. We're using Maildir here to serve both IMAP over SSL and POP3 over SSL. If you need any help in the setup of sendmail + procmail + dovecot, just tell me. Of course, if you're more experienced with Postfix, then use it. IMHO it's not as flexible as sendmail. But YMMV.

[Dovecot] GSSAPI authentication behind HA servers
by Mustafa A. Hashmi 22 Mar '07

22 Mar '07

Hi all, We have 2 mail servers sitting behind linux-HA machines.The mail servers are currently running dovecot 1.0rc2. Looking to enable GSSAPI authentication, I exported krb keytabs for imap/node01.domain@REALM and imap/node02.domain@REALM for both mail servers. However, clients are connecting to mail.domain.com, which results in a mismatch as far as the keytab is concerned (and rightly so). Connections directly to node01 and node02 work fine for gssapi auth. I proceeded to export a key for mail.domain.com into the same keytab for both the nodes, however, I don't think more than a single key is checked for the imap service, and authentication errors continued. Is anybody running something similar? Could you please explain how you have this working on your end? Appreciate any help. Regards, -- Mustafa A. Hashmi mahashmi(a)gmail.com

[Dovecot] Preparing for sharing with ACLs
by Mike Brudenell 22 Mar '07

22 Mar '07

Greetings - I'm finalising the layout of our new mailstore ready for a trial service using Dovecot (switching from the UW IMAP server). This is using Maildir mailboxes, changing from our current mix of MBX and traditional Berkeley. One of the things we are often asked for is how someone can grant another access to their mailbox: eg, a Head of Department wants the Departmental Secretary to review and reply to e-mails, but not tell her the password. I understand that Dovecot doesn't provide a user-interface for setting up or manipulating these, nor the IMAP ACL extension at this time, so... Q1. Are there plans to add support for ACLs in the future, along with an end-user accessible means of setting these up and manipulating them? I also understand that it is currently possible for the Mail Admin to set up ACLs (globally and/or per-mailbox) and shared folders (I admit I'm having trouble getting my head around the latter in the Wiki a bit). I' hoping to avoid using the current "has to be done by the Administrator" setup, and instead want to plan for any future end- user interface. We are using filestore quotas for the Maildirs, so at present a user's Maildir directories and files are owned by their username (UNIX uid) and group (UNIX gid). * Naturally for filestore quotas to continue to work items need to continue to be owned by the person's username (UNIX uid). When end-user support for shared mailboxes and ACLs comes along one day (hopefully!) I assume two levels of access control are needed: 1. At the filestore level the other authorised users will need read and/or write access to the directories and files comprising the Maildir, and 2. Suitable ACLs will be needed to grant access via Dovecot to authorised persons, but not to other random people. So looking to the future, I'm therefore thinking that instead of having each user's Maildir directories and files owned by their UNIX uid and gid I should instead have them owned by their UNIX uid and a common-to-everyone UNIX gid. Eg, drwxrwx--- user1:mail directoryname -rw-rw---- user1:mail filename I realise there is an element of risk here, as we would be relying on Dovecot's security to limit access so that only authorised users can access a given person's mailbox. Is this the right approach to adopt? Or is there a better way of (one day) enabling Person A to share their mailbox to Person B but not Person C? (We need a solution that is general and based on ACLs, not one that relies on our creating custom UNIX groups and assigning people's usernames to these.) I've read the Wiki pages on ACLs and Shared Folders, but am having trouble putting the information together in my mind to (one day) solve this particular requirement. Can anyone shed any light, please?

[Dovecot] corrupted transaction log error resulting in multiple deliveries
by Justin McAleer 22 Mar '07

22 Mar '07

I'm finally picking my dovecot project back up now, and after upgrading rc19 to rc27, I sent a test message to an existing account which resulted in log entries like these: Mar 16 08:45:37 node7 deliver(user(a)example.com): Corrupted transaction log file /var/indexes/example/com/u/us/user/.INBOX/dovecot.index.log: Append with UID 3, but next_uid = 15368 Mar 16 08:45:37 node7 deliver(user(a)example.com): msgid=<20070316124031.8F089D39A5(a)node7.neonova.net>: save failed to INBOX Mar 16 08:45:37 node7 postfix/pipe[29267]: 8F089D39A5: to=<user(a)example.com>, relay=dovecot, delay=306, delays=306/0.01/0/0.02, dsn=4.3.0, status=deferred (temporary failure) So, as you can see deliver has the problem and defers delivery. Is dovecot supposed to be able to recover from a corrupted log file on its own? It repeated this until I manually wiped out the index directory (didn't try just removing the log files first, sorry). The kicker is that deliver actually did save the message to the inbox every time, so multiple copies were delivered (every time I flushed the queue until it was actually fixed, a copy was delivered). I have my mail directories on an NFS mount, and indexes on localdisk, FYI.

[Dovecot] Throttling Logins
by Sean Kamath 22 Mar '07

22 Mar '07

Hi. Earlier today I was hit with 612 login attempts in 7 minutes. They ramped up slowly, too. :-) They quickly hit the file descriptor limit. And then a login server spawned and died so quickly that dovecot just died. My question is, is there a way to throttle the number of login connections? I'm doing it in my firewall now, but it would be nice to be able to say something like "max-login-attempts: X" before we blacklist the IP (for some configurable time). yeah, I know V4.2 :-) By the way, I *really* appreciate all the effort that's gone into Dovecot. Great work, everyone. Sean

[Dovecot] mail looping

We are running Postfix 2.3.3 and Dovecot 1.0-RC27 on a Solaris 10 server. We use the Dovecot LDA for local delivery. Problems arise with looping mail whenever a user's .forward contains a reference to themselves. This most frequently occurs when a user sets up a vacation since it then puts this in their .forward file: \username, "|/usr/bin/vacation username" The vacation program runs fine, and sends a notice back to the message originator, but when an attempt is made to deliver the message locally, it fails with: Mar 21 13:02:16 myhost.mydomain postfix/local[13373]: 3DF5A2C63: to=<systest(a)myhost.mydomain>, relay=local, delay=0.15, delays=0.12/0/0/0.03, dsn=5.4.6, status=bounced (mail forwarding loop for systest(a)myhost.mydomain) Any ideas?

[Dovecot] Timeouts connecting via POP3
by Don O'Neil 22 Mar '07

22 Mar '07

I'm experiencing timeouts from time to time from both Mac Mail and Outlook when connecting to my server. I originally suspected that it might be process # related, so I increased the auth & login process counts but that hasn't seemed to make a difference. I'm running 1.0rc10 which came with my DirectAdmin control panel. I'm wondering if this problem is known and was fixed in a later release? I'm waiting for instructions from the DirectAdmin folks on building a new version in case they do something special. Any ideas? Thanks!

[Dovecot] Comments about LDA wiki page
by Magnus Holmgren 22 Mar '07

22 Mar '07

I've just tried out Dovecot LDA. The reason I didn't want to use it before was that I found it unnecessary together with Exim, plus I wanted to use Exim's filtering. But now I wanted to see if can notice any improvement when the indexes are updated on delivery, and I saw that it's possible to use Exim filters and pass the resulting folder with -m. Now, correct me if I'm wrong, but IIUC some corrections, improvements, and comments could be made on http://wiki.dovecot.org/LDA. In the "Site-wide setup" section (and in dovecot.conf) it's suggested that access be restricted to the master socket somehow. The first Exim example ("System-users"), however, requires a world-writable socket. Uncomment "group = mail" and deliver will complain that setgid() fails. In this situation, the "-d $local_part@$domain" is unnecessary because then deliver will use the name of the user it's running as (it should probably have been just "-d $local_part" anyway). However, if deliver is run by root (which is by default impossible under Exim) or setuid root, then a destination user is mandatory. Oh wait, without -d the auth socket isn't used at all, only the HOME environment variable and default_mail_env are. Well, it shouldn't matter much if you're running a standard pam/passwd setup, but with a more complicated non-virtual setup I see only four solutions: Make deliver setuid root, remove root from the compiled-in FIXED_NEVER_USERS list, run deliver as a user/group that has write access to all mailboxes, or make the master socket world-writable. -- Magnus Holmgren holmgren(a)lysator.liu.se (No Cc of list mail needed, thanks)

Hi, I'm still trying to migrate a running qmail + vpopmail to sendmail + dovecot. I need the milter stuff from sendmail. I got sendmail + dovecot running using the migrated tables from the vpopmail DB, but I'm facing the UID problem in pop3. So, now I'm following the vpopmail authdb path. My questions are: - what do I need, a running vpopmail server (lib + binary, etc)? - or only the DB?

So as to make sure that Dovecot Sieve's vacation system works Exim has to be forced to generate a "Reply-To:" header in the message (which it doesn't do by default). The current example for using the Dovecot LDA with Exim doesn't do this. Here is a replacement example for the local_delivery transport:- local_delivery: driver = pipe command = /usr/local/libexec/dovecot/deliver -d $local_part message_prefix = message_suffix = log_output delivery_date_add envelope_to_add return_path_add headers_add = Reply-To: ${if def:header_reply-to:{$h_reply-to:}{$h_from:}} #group = mail #mode = 0660 Basically, if the Reply-To: header exists than it merely gets overwritten with itself. If it doesn't then the header is created and the contents of the From header is put into it. If this is not done then the libsieve over restrictive rules (requiring a "Reply-To:" header even though the RFC doesn't require it) will not allow the vacation system to work.

[Dovecot] Doubled mails and UIDs
by Adam Lackorzynski 22 Mar '07

22 Mar '07

Hi, I'm still seeing mails being downloaded twice via POP3 in my setup, running rc27. The log file shows: dovecot: Mar 18 22:08:05 Error: POP3(joe): mbox sync: UID inserted in the middle of mailbox /home/joe/Mail/INBOX (442671 > 80, seq=10, idx_msgs=153) dovecot: Mar 18 22:08:05 Info: POP3(joe): Disconnected: Logged out top=0/0, retr=153/1069109, del=153/153, size=1066449 The next POP3 connect will fetch most of the messages again. dovecot: Mar 18 22:18:48 Info: POP3(joe): Disconnected: Logged out top=0/0, retr=147/1006204, del=147/147, size=1003647 Is there a problem if an incoming message already contains an X-UID header? Might it be worthwhile to remove this header when mails are being delivered (e.g. with procmail)? Thanks, Adam -- Adam adam(a)os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/

[Dovecot] rc27 assert, mbox format
by Jeff A. Earickson 22 Mar '07

22 Mar '07

Timo, After several days of flawless work, rc27 gave an assert/core yesterday: Mar 19 00:10:46 karst dovecot: [ID 107833 mail.error] IMAP(user): file mbox-sync-rewrite.c: line 423: assertion failed: (need_space == (uoff_t)-mails[idx].space) Mar 19 00:10:46 karst dovecot: [ID 107833 mail.error] IMAP(user): Raw backtrace: 0x8a51c -> 0x473f4 -> 0x479b0 -> 0x41c50 -> 0x42430 -> 0x431d4 -> 0x43dac -> 0x44040 -> 0x2aa70 -> 0x2afec -> 0x2337c -> 0x23508 -> 0x235f0 -> 0x90c18 -> 0x9043c -> 0x2cfac -> 0x1dbe8 I could see nothing wrong with the user's mailbox, it was not corrupted. My setup: Solaris 10 sparc, mbox format, INBOX NFSv4 mounted from another S10 sparc system, no disk quotas, ZFS filesystem for both the INBOX filesystem and the user's home directory. Unfortunately, I compiled dovecot with Sun's cc compiler, so the gdb traceback is fairly useless. I need to go back to gcc. Jeff Earickson Colby College

[Dovecot] Double homedirs and tilde problems in case of chroot in passwd-file / static dbs.
by Michal Soltys 21 Mar '07

21 Mar '07

Recently I've made the post about "double homedir" problem, but I couldn't recreate it later. Here're the exact steps to make it happen (configuration is at the bottom): 1) set configuration as below with passwd-files 2) clean testms dir (not necessary though) 3) reload dovecot (HUP is enough) 4) access the server with any client using testms user (make sure no other user accesses server before you) - on the first access, dovecot will create /home/vmail/ppgk.com.pl/testms/Maildir under /home/vmail/ppgk.com.pl/testms/ - on every next access, dovecot will access (and create if it doesn't exist) proper Maildir under "single" home path Situation will repeat itself, if dovecot is reloaded (or killed and restarted). It happens to both imap and pop3. Note, that the a single access seems to be enough to "fix" the problem to all the other users in passwd-file, should there be any. The problem seems to be created by chroot specification in passwd-file & static (and possibly when other dbs are used). On the first access, dovecot attempts to recreate whole /home/vmail.... directory structure *after* chrooting to the homedir (or without taking earlier chroot into account), at least that's how it looks from ktrace. If I moved /./ to the left by one subdir, dovecot would attempt to do it under root owned /home/vmail/ppgk.com.pl/ and fail in the process. And so on. Tilde is another problem - if in dovecot.userdb I change - maildir:~/Maildir: to mbox:~/Mail:INBOX=~/inbox: - then single '~' directory will be created under /home/vmail/ppgk.com.pl/testms/, along the inbox file and Mail dir. If INBOX, CONTROL and/or INDEX is specified explicitely in maildir case, '~' won't be created. That leads to the questiom - is tilde allowed in INBOX under mbox storage at all ? I can't check '~' in INBOX/mbox case for system accounts atm though. If you need any more info (like ktrace), let me know.

[Dovecot] Index files in .imap directory
by Steven F Siirila 21 Mar '07

21 Mar '07

A few RC releases ago we had a problem where a user's restored home directory contained a .imap folder either from a previous RC release or perhaps it was a different server. In any event, restoration of the user caused problems since Dovecot choked on the restored .imap index files. Removing those index files cleared the problem. I'm wondering if this is still an issue, and therefore whether we need to find and remove all .imap folders prior to archiving users, so that they are not restored with potentially old/bad index files. I would like to NOT have to worry about them, but rather have Dovecot be smart about when to simply re-create them if it detects something it does not like about them. -- Steven F.

Hi Timo, What I did actually was change option (D) to the following below, or do I have to remove this one altogether? plugin { quota = maildir } Then added the attribute mailquota=10240 as I had defined in my dovecot schema And when I did a tried to run getquota "" or getquotaroot inbox (via telnet localhost 143), it would return me a "no quota" message. What I am able deduce is that the mailquota attribute did not take effect at all. Do you think I may have missed something out. And thanks for your prompt reply, really appreciate it.

[Dovecot] Adding ", S=size" to new message files when using "dirsize"
by Rich, Whidbey Telecom 21 Mar '07

21 Mar '07

When APPENDing new message files to an IMAP Maildir, Dovecot 1.0 rc27 can be configured to add ",S=size" to the filename. That allows it to be calculated with the "dirsize" quota plugin (and MTA's such as Exim). However, Dovecot only seems to do that when the "maildir" quota plugin is specified (from "quota-maildir.c"): /* For newly generated filenames add ,S=size. */ storage->save_size_in_filename = TRUE; Shouldn't "save_size_in_filename" be included in "quota-dirsize.c", since "dirsize" is the one that actually needs "S="? Maybe I'm missing something? Here're some relevant parts of our test config: -- mail_location = maildir:/var/mail/%u/Maildir:INDEX=MEMORY maildir_copy_with_hardlinks = yes maildir_copy_preserve_filename = yes protocol imap { mail_executable = /usr/local/libexec/dovecot/rawlog /usr/local/ libexec/dovecot/imap mail_plugins = quota imap_quota imap_client_workarounds = delay-newmail outlook-idle } plugin { quota = dirsize:storage=10240 } -- Thanks!

[Dovecot] Thanks!
by Kyle Wheeler 21 Mar '07

21 Mar '07

Hello, I just recently switched my system from a BincIMAP/vpopmail to a Dovecot/vpopmail system, and I have to say: thanks! There were really only two things I had to patch Dovecot to do: first, provide statistics on network usage, and second, to allow folders to be LIST'd/SELECT'd/etc. with a trailing separator (to satisfy my pine users). If anyone's interested, I can generate a patch for that stuff. Other than that, it's been a real breeze. Dovecot is really simple to configure, and is faaaaaaaast! We have a kind of a wonky setup (multiple domains, multiple SSL keys, etc.) and Dovecot hasn't gotten mad even once. Timo, thanks a bunch, it's an excellent piece of software. ~Kyle -- Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so. -- Douglas Adams

We used a cross-link cable between the two machines to transfer the data over their gigabit link. Both systems had three 10k rpm SCSI disks in hardware RAID 5 which pushed data at around 20 mb/s.

[Dovecot] a <blush> build/install question
by Stewart Dean 20 Mar '07

20 Mar '07

This is probably an idiot (and certainly so basic as to be non-Dovecot) question, but I have been chasing my tail for a day or so on it, so I will, with humiliation, ask for guidance on it. Some time back I had asked if dovecot had to have a whole build tree of stuff to run or if any upgrade could be limited to just the executable and some libraries. I was told the latter, and given this list: dovecot (the executable) dovecot.conf libexec/imap libexec/imap-login libexec/dovecot-auth I had wanted to structure my build and install work so that, when update came out, I could build into a directory that was stamped with the time and version and ssl inclusion status. Every time I built I would create a new directory, and I would be able to everything to fall back with, in the old directories. Being that this is production, I wanted to be able to uplevel (or fall back) quickly. I should say I build on a build machine, since I don't want to have a compiler on the production machines; I specified the stamped unique name of this build directory du jour using the --prefix confiigure parm The configure, make and make install steps all go fine. Now I have to transfer those five files over to the target production machine, where I had planned to reference these essential DC files, dovecot itself, dovecot.conf, etc through links, like this: (while resident in the build directory which has been NFS imported onto the production target machine) > cp -p ./sbin/dovecot /usr/sbin/$buildver.dovecot > ln -sf /usr/sbin/$buildver.dovecot /usr/sbin/dovecot > > cp -p ./etc/dovecot-example.conf /etc/dovecot-example.$buildver.conf > > cp -p ./libexec/dovecot/imap /usr/libexec/$buildver.imap > ln -sf /usr/libexec/$buildver.imap /usr/libexec/imap > > cp -p ./libexec/dovecot/imap-login /usr/libexec/$buildver.imap-login > ln -sf /usr/libexec/$buildver.imap-login /usr/libexec/imap-login > > cp -p ./libexec/dovecot/dovecot-auth /usr/libexec/$buildver.dovecot-auth > ln -sf /usr/libexec/$buildver.dovecot-au Alas, when I actually tried to run dovecot, it was asking for its resource /in the original build tree/ location, which wasn't there. Is there some way I can do what I want? It seems like I could run the configure without the --prefix parm and have these five files end up in the standard place, but then you would always be building in the same place. I would rather have them in a sheaf of unique build trees so there was never any confusion as to where an edition of them came from...one could always reference back to the unique build tree and do a sum on them. -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

Hello Torsten, We switched our 3500+ users from Qpopper to Dovecot last week-end. We had around 27Gb of data to migrate. We had a maintenance window in which we could stop the POP services, so it was quite easy to do. Even if we changed hardware, we kept the old name and IP so that we had no DNS changes to do. Clean and simple. Here's how we've done things on FreeBSD 6.2-RELEASE-p2 -- Shutdown qpopper POP services on the old machine. -- Create a tar and transfered it to the new machine. Acutally, this was a single step in which we used a pipe to send that tar STDOUT into ssh's STDIN. -- Import /etc/master.passwd and /etc/group from the old system into the new machine. -- Run a simple shell script to change from mbox format to Maildir using mb2md and set permissions. -- Exchange FQDN and IP between to old machine and the new one in order to prevent any DNS changes. -- Start Dovecot and your MTA on the new machine. Concerning your desire to move your user's Maildir into /var/mail/first_letter_of_username/username. It should be trivial to do using a simple /bin/sh script. Have fun !

[Dovecot] Sieve: Conversion script for procmail recipes.
by Stephen Usher 20 Mar '07

20 Mar '07

Seeing as many on this list are in the process of migrating their mailsystems not only to dovecot's IMAP/POP3 server but also using dovecot's deliver for delivering e-mail into users' folders I thought that it might be a good idea to share with you the perl script I've been labouring upon for the last few days which will translate a simple(ish) procmail recipe to an equivalent Dovecot-Sieve script. (It handles vacation pipes as well, by the way.) It may even be useful as a basis for a more fully featured translator, who knows. Whatever, if it could be put on the Wiki no doubt it will prevent the wheel being re-invented time and again. The script can be found at the following URL: http://www.earth.ox.ac.uk/~steve/sieve/procmail2sieve.pl It might be worth putting it in a contrib directory in the dovecot-sieve distribution.

[Dovecot] Outlook client timeouts on sending mail
by J Moore 20 Mar '07

20 Mar '07

This may be a sendmail question, but I thought I'd ask here first: I set up an Outlook client to use secure IMAP and secure SMTP. When sending a message, the client typically times out once or twice and presents an error message indicating the server isn't configured for secure delivery. With a little persistence, Outlook eventually makes a successful connection, and the message goes on its way (2-3 tries). Any pointers as to where to look for the problem? Thanks, Jay

[Dovecot] Best way to migrate from Qpopper to Dovecot
by Torsten 20 Mar '07

20 Mar '07

Hi List, what do you think is the best way to migrate (to a new maschine) round about 30000 mboxes (Qpopper) with an amount of 43Gigs data, to maildir format (Dovecot). I think there are two ways: 1. - stop services (smtp and pop3) on the old maschine - copy the mboxes to the new maschine - run a conversion script (for excample: "Perfect_maildir" http://perfectmaildir.home-dn.net/) - start the services on the new maschine (smtp and Dovecot) 2. - tell the users to use the new server (from the day X) with the new feature (imap) - stop the smtp on the old maschine on day X - leave the old maschine active for a month or so (let users get their "old" mail) With the first alternative we have a high downtime, because of copying the mboxes and converting the stuff. What do you think? Thanks Torsten

[Dovecot] Dovecot 'suicide'
by Luigi Rosa 19 Mar '07

19 Mar '07

I have a Dovecot installation on a Fedora 4. With the last update from Dovecot RC10 to Dovecot RC27, the daemon kills itself every night with this error: Mar 17 05:23:11 mail dovecot: Time just moved backwards by 6 seconds. This might cause a lot of problems, so I'll just kill m yself now. The error appears just after the night maintenance script executes a ntpdate syncronization ntpdate is version 4.2.0a(a)1.1196-r Well, 6 seconds are little more than a blink in human perspective, even if it is a long time for a computer point of view. Couldn't be possible to add a configuration option to avoid the suicide? Any other option other than suicide is better, because there could be situations of really unattended servers.

[Dovecot] Changed CONTROL= path causes POP3 to fail, whereas IMAP is working (rc25 & rc26)
by Steffen Kaiser 19 Mar '07

19 Mar '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm testing some configurations, in the process I used a wrong user setting causing POP3 (get new messages) to fail, whereas IMAP was still working. An easy fix was to remove the entire /var/cache/dovecot/1012/ directory, both index and index/control were re-created and do work. So my guess is that the existance of the indexes causes some trouble when just the control information is missing. Here is what I had done: The mailbox of "dvtest" was fully working with the correct setting from the config file: mail=maildir:/home/dvtest/MailDir:INDEX=/var/cache/dovecot/1012/index:CONTROL=/var/cache/dovecot/1012/control (no "/index" in the CONTROL= part). Then I created a LDAP entry for the user dvtest wrongly: mail=maildir:/home/dvtestMAIL/MailDir:INDEX=/var/cache/dovecot/1012/index:CONTROL=/var/cache/dovecot/1012/index/control The CONTROL= ended in "/index/control" rather than just "/control". (Note: I also mv'ed /home/dvtest to /home/dvtestMAIL in order to see, whether the LDAP attribute is getting used.) Afterwards IMAP is working, but POP3 returns "Couldn't init INBOX: Unknown error"; Thunderbird displays the error: "The STAT command did not succeed. Error getting message number and sizes. Mail server ux-2s11-9 responded: Couldn't sync mailbox." When I correct the LDAP attribute, hence the CONTROL= path ends in "1012/control" again. The mailbox is working with POP3 again. The INBOX of the erroreous control path does not contain any dovecot-* files? The message I deleted and expunged (see logs) were from the INBOX. /var/cache/dovecot/1012/index/control# lr .: total 16 drwx------ 4 dvtest Debian-exim 4096 2007-03-07 09:36 ./ drwx------ 12 dvtest dvtest 4096 2007-03-07 09:34 ../ drwx------ 2 dvtest Debian-exim 4096 2007-03-07 09:36 .Addresses/ drwx------ 2 dvtest Debian-exim 4096 2007-03-07 09:35 .INBOX/ ./.Addresses: total 24 drwx------ 2 dvtest Debian-exim 4096 2007-03-07 09:36 ./ drwx------ 4 dvtest Debian-exim 4096 2007-03-07 09:36 ../ - -rw------- 1 dvtest Debian-exim 12756 2007-03-07 09:36 dovecot-uidlist ./.INBOX: total 8 drwx------ 2 dvtest Debian-exim 4096 2007-03-07 09:35 ./ drwx------ 4 dvtest Debian-exim 4096 2007-03-07 09:36 ../ The attached file contains the full log of a session POP3 (get new messages), IMAP, expunge in INBOX, POP3 again.

Hello IMAP users here have a *lot* of folders living in their mailhub home directory Converting the INBOX doesn't seems to be a problem I've found scripts that do the job :-) But How to convert IMAP folders from UW format ( one file / folder ) to dovecot format which seems much more sophisticated. Does anyone has written such ( nice) utility ? Thanks a lot Frank

[Dovecot] using sieve plugin
by Kendall Shaw 19 Mar '07

19 Mar '07

Hi, I have installed dovecot on ubuntu edgy linux by retrieving the source debian package, building and installing the package and then building and installing the sieve plugin. However, I get no log messages indicating errors and as far as I can tell, my .dovecot.sieve script is not being used. I have introduced a syntax error in the script and see no error message. In dovecot.conf I have: log_path = /var/log/dovecot.log invo_log_path = /var/log/dovecot.log protocol lda { module_dir = /usr/lib/dovecot/modules/lda mail_plugins = cmusieve log_path = /var/log/dovecot-deliver.log info_log_path = /var/log/dovecot-deliver.log } I am using exim with dovecot. I've tried using a .forward file (I'm the one user on the computer). Alternately, I've tried creating the dovecot_deliver "transport" in exim and changing the localuser router to use it. Still, I get no messages from deliver and no error messages from dovecot or exim. The file dovecot-deliver.log is not created. Do you have any suggestions that can help me get it working or to see why it is not working? Kendall

[Dovecot] One user having reproducible IMAP issues
by Alex Boster 19 Mar '07

19 Mar '07

Dovecot version upgraded to 1.0r26 (did not fix problem). The server is a CentOS 4 x86 box. Using ext3 filesystem. Previous attempts to fix the issue have included simply moving aside the user's INBOX to recreating a new account from scratch. Sometimes the email behaves for a while, but within a day is not working again. In Mail.app (the user's usual mail client) the INBOX folder simply appears empty. mutt (run locally on the server) shows the messages there correctly. The problem is easily reproducible. Move /var/spool/mail/[username] to a backup file and remove all .imap directories for that user. Mail may work for a while, but will stop within 24 hours.

[Dovecot] authenticating with LDAP and SSL
by Nathan Fiedler 19 Mar '07

19 Mar '07

I managed to configure Dovecot to use a local OpenLDAP server to authenticate clients, without using SSL. However, I would rather that LDAP is accessed using SSL, but I cannot get Dovecot to connect. All that I did was change "uris" to "ldaps://localhost", and this appears in the maillog: Mar 18 12:53:00 server dovecot: Dovecot v1.0.rc15 starting up Mar 18 12:53:01 server dovecot: auth(default): ldap_bind((null)) failed: Can't contact LDAP server Is there additional configuration that is needed for SSL? Note that I altered the slapd.conf file from not requiring SSL to requiring SSL when I changed the "uris" parameter. And, of course, accessing the directory using ldapsearch works just fine. It seems that there's only a problem when using SSL, but I don't know how to debug it. Thanks n

[Dovecot] 1.0.rc27 released
by Timo Sirainen 18 Mar '07

18 Mar '07

http://dovecot.org/releases/dovecot-1.0.rc27.tar.gz http://dovecot.org/releases/dovecot-1.0.rc27.tar.gz.sig A few new small features and lots of index/mbox fixes. I've been heavily stress testing this release, so I think it should be about perfect. :) I think the only thing still missing from v1.0 is documentation. There are some unwritten pages in the wiki, and I still haven't bothered to write the wiki -> doc/*.txt conversion script. The script will probably be pretty easy, but writing the docs can take a while. + mbox and index file code handles silently out of quota/disk space errors (maildir still has problems). They will give the user a "Not enough disk space" error instead of flooding the log file. + Added fsync_disable setting. + mail-log plugin: Log the mailbox name, except if it's INBOX + dovecot-auth: Added a lot more debug logging to passdbs and userdbs + dovecot-auth: Added %c variable which expands to "secured" with SSL/TLS/localhost. + dovecot-auth: Added %m variable which expands to auth mechanism name - maildir++ quota: With ignore=box setting the quota was still updated for the mailbox even though it was allowed to go over quota (but quota recalculation ignored the box). - Index file handling fixes - mbox syncing fixes - Wrong endianess index files still weren't silently rebuilt - IMAP quota plugin: GETQUOTAROOT returned the mailbox name wrong the namespace had a prefix or if its separator was non-default - IMAP: If client was appending multiple messages with MULTIAPPEND and LITERAL+ extensions and one of the appends failed, Dovecot treated the rest of the mail data as IMAP commands. - If mail was sent to client with sendfile() call, we could have hanged the connection. This could happen only if mails were saved with CR+LF linefeeds.

I vote for first stabilizing the current new CVS HEAD, do a v1.1 release, and then put the ssl rewrite into CVS and plan to make that either v1.2 or v2.0.

[Dovecot] Connection closed by foreign host.

I installed dovecot on my system using the following configuration (in dovecot.conf): protocols = imap listen = * ssl_disable = yes login_user = nobody login_processes_count = 3 mail_extra_groups = nobody default_mail_env = maildir:/home/%u/Maildir auth default { mechanisms = plain passdb shadow { } userdb passwd { } user = root } After that I tested via telnet an got the message: Connection closed by foreign host.

[Dovecot] M-Box benchmark
by Maykel Moya 18 Mar '07

18 Mar '07

A friend of mine passed me this[1] cause I'm recommending him Dovecot. My personal experience is very different to the one in that benchmark. I will appreciate similar links from those of you who had benchmarked Dovecot against other IMAP servers. I'm conscious that my personal experience is far to be a objetive comparison. I switched from UW-Imap/Mbox to Dovecot/Maildir a box with 45k local users, 3.5MB/s sustained IMAP/POP traffic in work hours. The main performance gain is from mbox -> maildir switching. Anyway the users (and myself) "perceive" a good performance with the new setup. Regards, maykel [1] http://www.isode.com/whitepapers/mbox-benchmark.html

[Dovecot] pre-1.0.rc27: Index and mbox fixes
by Timo Sirainen 18 Mar '07

18 Mar '07

I've been doing some stress testing in the last few days and fixing all the errors I saw. I'm hoping that I've finally really fixed all the index/mbox problems. So, again I think the only thing left for v1.0 is the documentation. Please test this nightly snapshot before I'll release rc27 tomorrow: http://dovecot.org/nightly/dovecot-latest.tar.gz If you've seen any of the following error messages in log files, these should all be fixed now: - index: Append with UID 56297, but next_uid = 56298 - mbox: UID inserted in the middle of mailbox /home/tss/mail/inbox (45769 > 45768, seq=28, idx_msgs=30) - mbox: Expunged message reappeared in mailbox /home/tss/mail/inbox (UID 86957 < 86958, seq=28, idx_msgs=27) These should be fixed for most cases, but they can still rarely happen: - index: Extension reset without intro prefix There's a really tiny possibility of it still happening with mmap_disable=no, but I think it's practically fixed now. A proper fix would require more changes than I want to do for v1.0 (either support for marking transaction start/end positions or getting rid of the stupid intro prefix completely). - Cached message offset 38340 is invalid for mbox file /home/tss/mail/inbox This should happen only if you're using in-memory indexes or mbox_min_index_size isn't 0. This happens if the mbox file's timestamp and file size are the exact same after some expunges+appends, so the only way to properly fix it would be to wait a second and update the mtime before unlocking the mbox file after expunges. This sleep is actually already done when Dovecot notices that a) mtime and size really are the same after modification and b) mails have been moved around inside the file (ie. flag changes were done but there weren't enough empty space in the mail's own headers so mails had to be moved to get the needed space). Should be pretty rare. Anyway, this error is completely invisible to users and it doesn't have any other side effects that mbox_dirty_syncs doesn't already have. The whole error message could even be removed if it's going to become a problem.. Other changes in the snapshot: + mail-log plugin: Log the mailbox name, except if it's INBOX + dovecot-auth: Added a lot more debug logging passdbs and userdbs + dovecot-auth: Added %c variable which expands to "secured" with SSL/TLS/localhost. + dovecot-auth: Added %m variable which expands to auth mechanism name - Wrong endianess index files still weren't silently rebuilt - IMAP quota plugin: GETQUOTAROOT returned the mailbox name wrong the namespace had a prefix or if its separator was non-default

[Dovecot] flock problems with index files and passwd-file
by Michal Soltys 17 Mar '07

17 Mar '07

While experimenting a bit, I found that for some reason, locking indexes with flock is problematic, but only if user is taken from passwd-file. The host system is openbsd 3.9, dovecot's configuration is added at the bottom. Authentication is from two places - first from mentioned passwd-file, then from passwd file using bsdauth (in this case, there're no problems with flock). So, if a user is i.e.: test@domain.tld:{plain}test:20000:10::/home/regular/test::userdb_mail=maildir:~/Maildir Then the mail client will timeout (thunderbird in this case), and dovecot will leave following info in the logs: Mar 15 11:13:38 rasengan dovecot: IMAP(test(a)domain.tld): Effective uid=20000, gid=10, home=/home/regular/test Mar 15 11:13:38 rasengan dovecot: IMAP(test(a)domain.tld): maildir: data=~/Maildir Mar 15 11:13:38 rasengan dovecot: IMAP(test(a)domain.tld): maildir: root=~/Maildir, index=~/Maildir, control=, inbox= Mar 15 11:15:38 rasengan dovecot: IMAP(test(a)domain.tld): Timeout while waiting for lock for transaction log file /home/regular/test/Maildir/dovecot.index.log Happens both if in maildir and mbox (userdb_mail=mbox:~/mail:INBOX=/home/regular/test/mbx) cases. Locking through dotlocks or fcntl works well in all situations (passwd-file or not).

[Dovecot] LOCKD errors
by Jay Chandler 16 Mar '07

16 Mar '07

Running the nightly from two days ago. The Dovecot log shows no errors, but I keep getting login errors for a few users. top shows: 71486 user1 1 96 0 4552K 2408K lockd 0 0:00 0.00% imap 11170 user2 1 96 0 4440K 2480K lockd 0 0:00 0.00% imap And a ps aux shows that these processes have been open for hours. If I move the mbox that contains their mail, the same error still shows up. The mboxes reside on our NetApp which is NFS mounted-- does anyone have any wisdom regarding this? As best I can tell this hasn't been a problem before the last few RCs, though I could be mistaken on this. -- Jay Chandler Network Administrator Chapman University

[Dovecot] wiki -> txt
by Timo Sirainen 16 Mar '07

16 Mar '07

I've been trying to fix MoinMoin's text_plain formatter to produce readable output. It's almost correct, except I don't understand why I can't get the LF-adding rules correct. Either there are too many LFs or too few. And whenever I change something, something else breaks.. It's getting pretty annoying. So if anyone else wants to try getting it fixed that'd be great. :) Attached the current version that I have. For testing you'll need your own MoinMoin installation. Then replace the included text_plain.py with the attached version. Then test it with for example: http://localhost/wiki/SomePage?action=format;mimetype=text/plain

[Dovecot] crypt missing (configure problem)
by Fabio Busatto 16 Mar '07

16 Mar '07

Hi, I need some feedback for the following problem I encountered compiling dovecot. It seems to be a wrong check in configure, that comes out in a fatal error (crypt symbol not found because the -lcrypt is omitted). With these configure parameters no crypt module is recognized (and so the need_crypt variable is still off), but at compile time gcc fails to create executables.

[Dovecot] BUG: Unexpected input from auth master:
by Justin McAleer 16 Mar '07

16 Mar '07

deliver logs the error in the subject whenever the userdb lookup fails. I had a query discrepancy between postfix and dovecot, so messages were accepted that shouldn't have been, but I figured deliver should probably handle that a bit more gracefully :)

[Dovecot] sasl authentication via dovecot
by Frank Church 16 Mar '07

16 Mar '07

I am setting up a Postfix/Dovecot/Virtual Domains system, with virtual tables using Postfixadmin and MySQL. Incoming mail is accepted for the virtual mailboxes, but when I try to retrieve mail from Outlook or Thunderbird I get errors You cannot log in to abc.server.net because the server has disabled login. You may need to connect via SSL or TLS. Please check the account settings for your mail server As Dovecot is handling the auth I suspect that it is where the problem lies. Are they any faults in the settings below that could be the cause? As I understand it because Dovecot is handling the login and monitoring the IMAP and POP ports. All the initial authentication is supposed to be handled there before Postfix gets involved. Running lsof -i:port on ports 110, 143, 993 and 995 shows that dovecot is handling all those inbound connections. I am also seeing messages in the log as follows dovecot: imap-login: Aborted login: rip:81.150.x.x, lip=66.90.x.x my auth section in Dovecot is as follows auth default { mechanisms = plain login passdb sql { args = /etc/dovecot/sql.conf } userdb sql { args = /etc/dovecot/sql.conf } userdb prefetch { } user = nobody socket listen { master { # path = /var/run/dovecot/auth-master path = /usr/local/var/run/dovecot/auth-master mode = 0660 user = vmail group = mail } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = mail } } } My sql.conf is as follows driver = mysql connect = host=localhost dbname=postfix user=dovecot password=password user_query = SELECT concat('/var/vmail/', maildir) as home, concat('maildir:/var/vmail/', maildir) as mail, 601 AS uid, 12 AS gid, concat('dirsize:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1' password_query = SELECT username as user, password, concat('/var/vmail/', maildir) as userdb_home, concat('maildir:/var/vmail/', maildir) as userdb_mail, 601 as userdb_uid, 12 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' this is the smtpd section from main.cn # ---------------------- SASL PART START ---------------------- smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes #smtpd_sasl_local_domain = $myhostname smtpd_sasl_exceptions_networks = $mynetworks smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes # ---------------------- SASL PART END ----------------------

[Dovecot] Warn before overquota
by Joan 16 Mar '07

16 Mar '07

Looking in the archives I found a message from dominik.saar(a)1und1.de on the 16/08/06, that is asking for a system to control the overquota warnings from within dovecot or dovecot LDA. The proposed solution is to use exim as MTA, since it has build in support. In my case I'm using postfix, what would be the recommended approach in that case? I was thinking of something like the cyrus LDA that you can with deliverquota [ -w percent ], something like that in a quota aware LDA would be quite useful for me. Any proposed solution would be welcome. Thanks

[Dovecot] running DC and UWIMAP on the same box
by Stewart Dean 15 Mar '07

15 Mar '07

It never hurts to ask...... I am bringing up DC on my production mailserver (which runs UWIMAP for production IMAP service) to learn and test it, much as I did when I introduced SSL protected IMAP, using an unpublicized non-standard port. The folder and mailbox location and format will remain the same. Questions: 1) Will DC be building indices for everything or just for the userid that I use to request client service for? 2) Are there any pitfalls others have experience doing this? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Postfix+Dovecot+LDAP
by Ejay Hire 15 Mar '07

15 Mar '07

This message does not contain a bug report or any issues. It is a summary of my experiences with Postfix, Dovecot, and Ldap. 1. Do not use Dovecot 0.99, even if it's what your vendor has packaged. 1a. ... When you upgrade past 0.99, you'll get some double mail because of UIDL's. 2. Do not use PAM and Ldap and then let dovecot talk to pam. It is bad. Don't do it. 2a. Unless you like users digging around in random mailboxes. 2b. NSCD is broken and should not be trusted. 3. Dovecot+Ldap works, and works well. 3a. If you don't do "Auth Binds", it cuts the work on the ldap server in half. 3b. User Prefetch cuts that in half again. 4. Postfix+Ldap works, and works well. 4a. If your server is underspec'd, you may get the occassional "Temporary lookup failure" 400 error during periods of heavy load, specifically when backups are running. 5. OpenLdap works. 5a. When you run as ldap, the config files need to be owned by ldap. 5b. ... And the database 5c. ... And the schema 5d. Adding slapd_db_recover to the init script isn't a bad idea. 6. Don't be dumb. 6a. ... Like me. 6b. If you are using ldap to lookup the attribute mail, index the mail attribute. 6c. If you add an index to Openldap, you have to reindex the database with slapindex 6d. ... Or you bounce a lot of mail before you figure it out. 6e. Make sure you can login to the console and/or ssh if the ldap server dies. 6f. ... Be Really sure. 6g. The convert plugin can switch users between maildirs and mboxes.

Thank you for the reply of my previous post (http://www.dovecot.org/list/dovecot/2007-March/020716.html) now it works, but I have another question about migrating pop3 account (with leave mail on server) to maildir. On this post -> http://www.dovecot.org/list/dovecot/2006-February/011464.html you explain how to create dovecot-uidlist preserving UIDVALIDITY. Is there someone that have build a script to generate such dovecot-uidlist? thank you all

[Dovecot] Alerts and pre-authenticated connections
by Mike Brudenell 15 Mar '07

15 Mar '07

Greetings - Work moves onward here at setting up our Dovecot IMAP service and I've got a couple more questions, I'm afraid... :-} ============================================== Q1. The UW IMAP Server supports "pre-authenticated connections" -- does Dovecot? Specifically, it is possible to create a symlink from /etc/rimapd to the UW IMAP server binary and then use rsh or ssh from within the Pine mail client to execute that on the server to establish the IMAP connection: rsh imap.york.ac.uk /etc/rimapd Pine uses this to open a "pre-authenticated" connection to the UW IMAP server to avoid the user having to enter their username and password -- the rsh/ssh mechanism provides the IMAP server with the user's login name. I've grepped the Dovecot source but it looks like it doesn't support this. Am I right in thinking this? ============================================== Q2. The UW IMAP Server can issue "IMAP Alerts" The UW IMAP server can issue a sequence of one-line notices to mail clients using IMAP's ALERT mechanism. The notices are formed formed from each line in a systemwide file (if non-empty) and a per-user file (~/.imapalert). Many, but by no means all, mail clients display these notices to the user -- currently we use this mechanism to advise people who have totally run out of mail quota. I've grepped the Dovecot source for "alert" but it looks like the IMAP Alert mechanism isn't supported. Am I right in thinking this? ============================================== Cheers, Mike B-) -- 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] imap connection problems

Hi, Have encountered some strange behavior of dovecot: after few days of work (5-7 days, ~50 users, imap over ssl or tls) dovecot stops respond with "* OK Dovecot ready.". I.e. connection gets accepted, but no response from dovecot: [ivan@dyn-226 bin]$ telnet imap 143 Trying 192.168.100.9... Connected to imap.n-ix.com.ua (192.168.100.9).

Escape character is '^]'. * OK Dovecot ready. After dovecot restart everything works OK. This behavior we started to observe since rc24, before that on rc9 we didn't see that problem. Currently running on rc26. Any ideas? Thanks, Iv

Now that it can pull this from index files, it would be pretty sweet if there was a variant of the STATUS command that would provide STATUS information for all mailboxes at once, rather than just for one. This could be used by webmail applications to update a folder listing that shows unseen mail counters with one command. Like maybe: a1 X-LIST-STATUS (MESSAGES UNSEEN) * X-LIST-STATUS "INBOX" (MESSAGES 8 UNSEEN 0) * X-LIST-STATUS "Drafts" (MESSAGES 0 UNSEEN 0) * X-LIST-STATUS "Trash" (MESSAGES 89 UNSEEN 3) a1 OK X-LIST-STATUS complete.

[Dovecot] [PATCH] fix gcc warnings in 1.0rc26
by Max Kellermann 15 Mar '07

15 Mar '07

Hi, I have made a small patchset to fix some of the GCC warnings. With these patches, I was able to compile dovecot r_1_0_rc26 with the following options: -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast Wstrict-prototypes -Wredundant-decls -Wcast-align -Wwrite-strings Wpacked -Winline -Wdisabled-optimization -Wno-long-long -Wundef Wfloat-equal -Wsign-compare -Waggregate-return -Werror Some of the changes may be arguable, escpecially the const warning fixes, example: char *pass = ""; I changed that to "pass = NULL" and changed the function call: - auth_request_verify_plain(request, pass, + auth_request_verify_plain(request, pass == NULL ? "" : pass, In other sources, I added "const" to parameters or to the return value where it seemed to make sense and didn't cause harm. Dealing with the const problem can be tricky, and sometimes dirty deconstification hacks are the only way to go.. however I believe we should always turn on "-Wconst" and explicitly add manual deconstitication where we assume it's not dangerous. I didn't fix all "const" and "missing noreturn" warnings, but my patches may be a good start... if there is further interest in fixing all of them, I'd be glad to do it. Max

[Dovecot] Problems with seen flag on OS X mail
by Nicolas Cianca 15 Mar '07

15 Mar '07

I'm having a problem with dovecot and apple mail not always remembering the seen flag. Some cases when mail is read it stays that way but other times it reverts back to unread on the next connection. I've tried to rebuild the Apple Mail mailbox but that doesn't do it. The mail is stored in Maildir format in the users home directory. All the connections Apple Mail are done via IMAP. I'm currently running rc27 on Centos and this has been ongoing since I switched from cyrus about 3 months ago. Any suggestions? nicolas cianca LIGHTBULB ncianca(a)lightbulb.com

Hi, Been reading a lot of posts about dovecot configuration, but can't really figure out if what I want is even possible or how to achieve this. My setup is simple : One linux machine that collects mail from my provider and sorts them for me and my wife, where my email is stored in Maildir format in ~myuser/.maildir and my wife's email is stored in mbox format in /var/spool/mail. Before making my wife crazy with a new way of getting and reading email with IMAP, I tried to do the following : My PC (not the linux server) runs either linux or XP, and the client I'm using is Evolution 2.8.2.2. I can get my email using IMAP without problems. My wife's PC just runs XP and the email client is Outlook which gets its email from the linux server through pop3. I've setup Dovecot to service both IMAP and POP3. The default_mail_env is now set to maildir:~%u/.maildir (which of course only reflects Evolution's IMAP need on my own PC) Now for the big question: How can I achieve that when I get email from the server using IMAP, I will automatically just look in the Maildir location (~%u/.maildir) __AND__ when my wife logs on through POP3, dovecot will only look for her email in her mbox directory /var/spool/mail/... ? In other words, different protocols used by (two) different users need to look for email in different locations (maildir and mbox). I tried to get this working using the Namespaces thingy in dovecot, but couldn't get it to work. Any suggestions (hyperlinks) are most welcome. Thanks, Hans

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

15 Mar '07

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

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

15 Mar '07

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

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

15 Mar '07

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

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

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

14 Mar '07

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

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

14 Mar '07

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

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

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

14 Mar '07

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

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

14 Mar '07

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