[Dovecot] Static home while using LDAP
by David Bosque 29 Oct '07

29 Oct '07

Hello all, I've been googling for a workaround for this for nearly a week to no avail and I hope someone in the list can shed some light on it. I have downloaded and compiled dovecot 1.0.5 and applied the quota-warning to it. I have configured everything and it's working wonderfully, even the lda with the sieve plugin. This is my current relevant configuration: userdb static{ args = uid=501 gid=12 home=/var/mail/buzones/%d/%n allow_all_users=yes } passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } However, I need to obtain some more data from LDAP, so I need to switch to an ldap userdb, but want to keep the home as it is in the static configuration and not having to store it in LDAP. Is it possible to use a fixed home (as in the static userdb) while using an ldap userdb? I am looking for something similar to user_global_uid and user_global_gid but for the "home". If not, is it possible to fix or append something to the values in the user_attrs (like the following)? user_attrs = [whatever_i_want_to_append]uid=home uidNumber=uid,gidNumber=gid Regards, David Bosque

[Dovecot] v1.0.7 released

29 Oct '07

http://dovecot.org/releases/1.0/dovecot-1.0.7.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.7.tar.gz.sig Almost missed this one. I had already fixed it in v1.1 tree, but forgot to fix in v1.0 tree. - deliver: v1.0.6's "From " line ignoring could have written to a bad location in stack, possibly causing problems.

[Dovecot] lost emails with version 1.0.6
by Nishant Limbachia 29 Oct '07

29 Oct '07

Hi list members, I am using dovecot on Slackware 12.0 with postfix 2.4.5. I just upgraded to version 1.0.6 from 1.0.5 and now I am not getting emails. I am using dovecot deliver with postfix. deliver log also says email put into appropriate inbox. Starting up dovecot doesn't show any error messages. I've looked at the release notes and couldn't find any changes that should affect the config file. Here's an excerpt from dovecot deliver's log for the last two emails I've lost after upgrade. ### deliver(raghu): Oct 28 19:34:52 Info: msgid=<200710281935.AA6815928(a)stuart.iit.edu>: saved mail to INBOX deliver(raghu): Oct 28 19:40:13 Info: msgid=<200710281940.AA82444392(a)stuart.iit.edu>: saved mail to INBOX ### Any ideas? ---- tuxrules.in(a)gmail.com

[Dovecot] do 1.1b4 assertion failed: (mailbox_list_is_valid_existing_name
by Adam McDougall 28 Oct '07

28 Oct '07

I think this is where I left off last weekend. Instead of this happening at the base of one of my shared mail namespaces, it happens when I try to select a top level folder inside the namespace, or try to directly select an entire path to a folder. This only happens when ACL is enabled. Let me know if I need to provide more. Thanks.

[Dovecot] fallback for proxy?

Is it possible somehow to configure a fallback for a failed proxy? I am using sql based proxying through dovecot, but it would be nice if you can fallback to another host if the proxy destination server is down. High availability and all.. Regards, Cor

[Dovecot] More core dump stack traces
by Lloyd Parkes 28 Oct '07

28 Oct '07

Hi all, I found a whole bunch of core files from imap this evening, so here are the stack traces from each. Unlike my last message, I don't have debugging symbols for these, so there isn't any analysis I can easily do. There were several cores with the first stack trace and one with the second trace. The core dump for the second trace is the only one I noticed. I suspect that the first trace happens when the client host goes to sleep. If so, the situation needs to be handled more gracefully. I'm currently building a copy of imap with debugging symbols.

[Dovecot] Possible Caching Bug showing up as a MIME Boundary Issue
by Kevin A. McGrail 27 Oct '07

27 Oct '07

Possible Caching Bug showing up as a MIME Boundary Issue I'm using Dovecot version 1.0.0. I was using Dovecot version 1.0.0 beta3 or alpha4. I upgraded to Dovecot 1.0.0 to make sure that was not the issue. Over the past few weeks on a server running a stable dovecot, I have seem a few emails arriving where the MIME document structure dividers are visible. I've included a screenshot showing this. Using OE6 as client. Have tried adding oe6-fetch-no-newmail per clients wiki but this seems to stop the ability to login at all. I am using two different machines with Outlook Express to access the same email. The same problem will show up on both. Usually, if I delete the .imap cache for the folder, the email comes down correctly. My dovecot -n output is: # /etc/dovecot.conf listen: *:144 ssl_listen: *:994 ssl_cert_file: /usr/local/ssl/certs/stunnel.pem ssl_key_file: /usr/local/ssl/certs/stunnel.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login max_mail_processes: 50 verbose_proctitle: yes default_mail_env: mbox:~/:INBOX=/var/spool/mail/%u mail_location: mbox:~/:INBOX=/var/spool/mail/%u imap_client_workarounds: outlook-idle delay-newmail auth default: passdb: driver: pam userdb: driver: passwd userdb: driver: prefetch The server is on a heavily modified RedHat 7.2 on x86 box with ext3 Thanks in Advance, KAM

[Dovecot] trouble deleting folders that only contain folders
by Ken A 27 Oct '07

27 Oct '07

Hi, I'm using dovecot 1.0.5 with mbox storage. Users can't delete folders that are created to 'only hold other folders'. I can create these folders with no problem. They are directories in the file system. Normal folders (which are mbox files) are deleted with no problem. I've tried with both squirrelmail and Thunderbird, and what happens when a delete is requested, is that all files within the folder's dir tree are deleted and the client is unsubscribed, but the directory tree remains. Any ideas? Thanks, Ken -- Ken Anderson Pacific.Net

[Dovecot] 1.1b3 and Maildir quota
by Rick Romero 27 Oct '07

27 Oct '07

I upgraded a 1.0 install to 1.1b3. Almost everything is working peachy-keen :) It seems faster to me, Offline Folders and 'new mail' options for Thunderbird are now working, and Mail.App doesn't seem to need the extra namespace. Unfortunately it doesn't seem to read my quotas any longer. I went through the docs, and I see the quota plugin has changed, but there doesn't seem to be a needed configuration change.

[Dovecot] quota problems - which Dovecot version ?
by Albert Schweizer 27 Oct '07

27 Oct '07

Hi, I've got a little problem with Dovecot IMAP. Everything works nice ( pam auth, ldap userdb, and so on ) BUT i need to uses quotas and it doesn't seem to work. I tried both ways : 1) user dovecot-ldap.conf with user_attrs, as it's shown on dovecot wiki ; 2) use the commandes "plugin {.........." in dovecot.conf But it didn't work. Strangely, when i try to use the PLUGIN command in dovecot.conf, the server crashes at start, "syntax error" in config.... I'm not sure if the quotas are supported in my Dovecot version : version : 0.99.14 release : 1.EL4 I'm using an old AlphaServer ( dec ) with Centos 4.2 installed, and it's a real mess to get yum updates. Building from sources neither worked.... Please help !!! Regards Y.V.

[Dovecot] Duplicate message
by Timothy Murphy 27 Oct '07

27 Oct '07

I'm running dovecot on my desktop and using kmail as a client on my laptop. I am very happy with this - I was previously running kmail under NFS, and this is infinitely better. There is one small issue, which is not very important. I get a small number of messages apparently duplicated. This doesn't really matter, as there is a facility Folder=>Remove Duplicate Messages under kmail, and this deals with the issue easily enough. I just wondered though why I get the duplicate messages, and if there is some simple way to avoid them?

[Dovecot] dovecot-auth: Too many open files
by Joe Allesi -X (joallesi - Coyote Creek Consulting at Cisco) 27 Oct '07

27 Oct '07

All, [version: dovecot-0.99.11-4.EL4.src.rpm] We recently experienced an issue that prevented all new IMAP logins from occurring. Although it appears that it was due to running out of available system file descriptors, I'm still not sure what the true root cause was as I can't replicate the same error in our test environment. The system file descriptor max was set at (per `cat /proc/sys/fs/file-nr`) 380081 , and we're averaging around 7,000 in use. It appears that the main issue was dovecot-auth, so does this appear to fall in line with the known PAM bug in this version? Auth config: auth_userdb = passwd auth_passdb = pam Checked maillogs (cleansed): Oct 16 11:48:05 host dovecot-auth: PAM: pipe() failed: Too many open files Oct 16 04:48:06 host imap-login: Disconnected [::ffff:<internal_IP>] Oct 16 11:48:11 host dovecot-auth: PAM: pipe() failed: Too many open files Oct 16 04:48:11 host imap-login: Aborted login [::ffff:<internal_IP>] Oct 16 04:48:11 host dovecot-auth: PAM unable to dlopen(/lib/security/pam_nologin.so) Oct 16 04:48:11 host dovecot-auth: PAM [dlerror: /lib/security/pam_nologin.so: cannot open shared object file: Too many open files] Oct 16 04:48:11 host dovecot-auth: PAM adding faulty module: /lib/security/pam_nologin.so Oct 16 04:48:11 host dovecot-auth: PAM unable to dlopen(/lib/security/pam_stack.so) Oct 16 04:48:11 host dovecot-auth: PAM [dlerror: /lib/security/pam_stack.so: cannot open shared object file: Too many open files] So, during the event I performed an strace against the dovecot-auth process and noticed the following error as well: accept(3, 0xbfe05a50, [2]) = -1 EMFILE (Too many open files) gettimeofday({1192538310, 41972}, NULL) = 0 poll([{fd=3, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL, revents=POLLIN}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=18, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=10, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=23, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=8, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=11, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=12, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=13, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=14, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=19, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=16, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=17, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=6, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=15, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=20, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=21, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=9, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=22, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=24, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=25, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=26, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=27, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=28, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=34, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=33, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=29, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=37, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=30, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=31, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=41, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, ...], 1020, 1585) = 1 gettimeofday({1192538310, 99354}, {480, 0}) = 0 Then I checked for the current network connections: netstat | grep imap | wc -l 42 Then used lsof to check for open files: while true ; do lsof | awk '{ print $3 }' | wc -l ; sleep 4 ; done 21728 21668 (restarted dovecot) 1838 1953 1864 2066 2018 2020 2036 2189 2661 2558 2490 (cont @2,000) Thanks!

[Dovecot] Problem in mbox-sync.c
by Hal Pomeranz 27 Oct '07

27 Oct '07

We've just cut over to a new mail server running Dovecot 1.0.5. The underlying OS is RHEL 5. User mailboxes are stored in Unix mbox format on a local ext3 file system. The MTA on the system is the default RedHat version of Sendmail 8.13.8 with procmail for local delivery. We're using a combination of dotlock and fcntl style locking. The output of "dovecot -n" for this system appears below my signature. Periodically we see errors like the following in our logs: Oct 21 19:36:01 postoffice1 dovecot: POP3(someuser): file mbox-sync.c: line 1433 (mbox_sync_handle_eof_updates): assertion failed: (file_size >= sync_ctx->expunged_space + trailer_size) Oct 21 19:36:01 postoffice1 dovecot: POP3(someuser): Raw backtrace: pop3 [0x809eda1] -> pop3 [0x809ecbc] -> pop3(mbox_sync+0x1088) [0x806c4e8] -> pop3(mbox_storage_sync_init+0x3e) [0x806cb6e] -> pop3(client_create+0x1a4) [0x80552a4] -> pop3(main+0x556) [0x8057236] -> /lib/libc.so.6(__libc_start_main+0xdc) [0x304dec] -> pop3 [0x8054a11] Oct 21 19:36:01 postoffice1 dovecot: child 24409 (pop3) killed with signal 6 Note that while the above log is for a POP3 user, we also see similar behavior when some users access mail folders via IMAP as well. The real problem with this behavior is that sometimes, but not in all cases, the process will leave behind a dotlock when it exits. If the abandoned dotlock is on the user's inbox, then procmail won't deliver new mail to the user until the lock is cleared. This is a big problem. Anybody seen this behavior before and/or know what's causing it? Can anybody suggest ideas for further debugging this issue? We'd appreciate any help that you all can provide.

[Dovecot] master user can not login with digest-md5 password
by Daniel 27 Oct '07

27 Oct '07

Hi! I'm trying to use a master user, here is what I'm doing: dovecot.conf: auth default { [...] passdb passwd-file { args = /etc/dovecot.passdb_master pass = yes master = yes } passdb passwd-file { args = /etc/dovecot.passdb } [...] } (Dovecot said that one can not place the passdb containing "master = yes" last, why?) This only works if the master user (in the master passwd file) has PLAIN password scheme. It doesn't work with DIGEST-MD5. Here is the log when it's in DIGEST-MD5: auth(default): passdb(master,84.x.x.x,master): Master user logging in as leva auth(default): digest-md5(leva,84.x.x.x): password mismatch imap-login: Disconnected: user=<leva>, method=DIGEST-MD5, rip=84.x.x.x, lip=212.x.x.x, TLS When the master password is in PLAIN scheme, I can login as anyone. I'm using dovecot-1.1beta4. Daniel

[Dovecot] Messages not marked as read
by Manilal K M 27 Oct '07

27 Oct '07

Hello everybody, Recently I have migrated my IMAP server from Courier-IMAP to dovecot. The migration was successful and all the users are happy due to the speed of the new IMAP server. We are using Horde-3.2+IMP-4.2 as the webmail client. But one of the users is having some unusual issues with his mailbox. Whenever he clicked and open a new email, it's never marked as read. He has to click and open several times to get it marked as "Read". I checked the dovecot version and found that we have a unstable version. So I upgraded to the latest stable version(1.0.5). But still occasionally he has the same issue. Does anyone have experienced similar issue. Please share. regards -- Manilal K M. http://linuxeyes.blogspot.com http://flossvalley.blogspot.com Better to light one candle than to curse the darkness.

[Dovecot] Keywords (labels) support via virtual folders
by Robert Tomanek 27 Oct '07

27 Oct '07

Hi all, while I am rather a beginner when it comes to IMAP, I was thinking whether it would be possible (and feasible) to implement setting and unsetting of IMAP keywords with the means of virtual folders in Dovecot. The background is that the IMAP keywords seem to be a very useful thing to me: I would often like to be able to 'tag' a message so that it is easy to group with other similar messages and easy to find/ browse later. The problem is that not all IMAP clients support this functionality (as far as I am aware, mine which happens to be The Bat! does not); the only way of achieving similar results is using regular folders for grouping messages but this has several disadvantages, the most prominent one being unable to assign more than one 'tag' to a message this way (without copying a message). What I am thinking of is a server-side 'helper' that intends to achieve functionality similar to native client keywords support by the means of providing 'virtual folders' (as opposed to regular folders that we've known for a long time). The server would expose a list of virtual folders (user defined, either server-side by modifying the configuration, or client-side, by using the existing 'create regular folder' folder functionality but using a special name format that would be recognized by the server to be virtual folder related). These virtual folders would, upon moving a message to them, apply a keyword to the message (but the message would not be moved as it would be the case with regular folders). Upon moving a message from a virtual folder, the keyword would be reset. This means that the messages would not normally be moved from their place in existing hard folder structure but they would additionally be flagged with a keyword (or more of them) and be visible in respective virtual folders. The result is: - keywords support for clients that do not natively support it, - leaving existing message folder structure intact, - support for multiple keywords/ labels per message (one virtual folder = one keyword), - browsing flagged messages via respective virtual folders. What do you think of it? While I've been toying with this and similar ideas for a long time, what I propose above is of course heavily influenced by the recent addition of IMAP access to Gmail ([1]). While I still do not have it enabled for my account, I presume this is how the Gmail labels get translated to IMAP client ([2], [3]).

[Dovecot] few questions about 1.1*
by Daniel 27 Oct '07

27 Oct '07

Hi! I'm testing 1.1, and have some questions. (How) Can I override the default maildir++ quota setting (I mean quota_rule) in the userdb, so that one won't have quota at all. Right now I'm setting a very high limit in the userdb with quota_rule=*:storage=99G in the extra field. Prior to 1.1 I was using 1.0 and had fs quota. I've had set up dovecot so that the indexes were stored on another partition where there were no fs quotas for the users. Now I'm trying to use maildir++ quota, and wondering if there is still any use of keeping the index files on a separate partition. This will be maybe a bit stupid, but do I still need the quota plugin to be loaded in the protocol {imap,pop3,lda} sections if I'm using the above mentioned new 1.1 maildir++ quota? Furthermore, will deliver be aware of the new quota system? Thanks! Daniel
