[Dovecot] ENVELOPE mishandling of Subject lines with quote(s)?
by Dinh Le 07 Feb '12

07 Feb '12

Hi, I am running dovecot version 1.2.9 on a Ubuntu 10.04 server. To obtain the message's header info from this dovecot imap server, I run the following imap command on a client side's imap session: . fetch 88:90 (envelope) which returns (in this case) ------------------------------------------------------------- * 88 FETCH (ENVELOPE ("Tue, 28 Oct 2008 15:45:35 -0500" "Linear Actuators Bring Flexibility to Packaging" (("Design World" NIL "subscription" "designworldonline.com")) (("Design World" NIL "subscription" "designworldonline.com")) (("Design World" NIL "subscription" "designworldonline.com")) ((NIL NIL "dinh" "flic.net")) NIL NIL NIL "<490779CF.00000E7D(a)ak119.mta.exacttarget.com>")) * 89 FETCH (ENVELOPE ("29 Oct 2008 15:44:03 -0500" {65} 2nd Edition of Brennesholtz/Stupp "Projection Displays" Available (("Insight Media" NIL "administrator" "insightmedia.info")) (("Insight Media" NIL "administrator" "insightmedia.info")) (("Insight Media" NIL "administrator" "insightmedia.info")) ((NIL NIL "dinh" "flic.net")) NIL NIL NIL "<20081029154358.0C359AE169595F1B(a)insightmedia.info>")) * 90 FETCH (ENVELOPE ("Thu, 30 Oct 2008 04:24:31 +0800 (SGT)" "6 new products Now Online!" (("Global Sources Product Alert" NIL "paservices" "globalsources.com")) (("Global Sources Product Alert" NIL "paservices" "globalsources.com")) (("Global Sources Product Alert" NIL "paservices" "globalsources.com")) (("Dinh Le" NIL "dinh" "flic.net")) NIL NIL NIL "<352725277.1225311871753.JavaMail.web(a)fuchsia3.globalsources.com>")) . OK Fetch completed. -------------------------------------------------------------- Notice that message 89's Subject line Subject: 2nd Edition of Brennesholtz/Stupp "Projection Displays" Available has quotes and this dovecot's ENVELOPE response failed to get parsed by a popular Perl module (Mail::IMAPClient::BodyStructure::Envelope). I have a hunch that this is dovecot's fault but I could be wrong. How should dovecot (or any imap server) deal with Subject lines with quotes inside ENVELOPE? ENVELOPE seems to encapsulate most of the important information and its format can be parsed cleanly and quickly. I prefer to fetch ENVELOP, at this point, rather than the other alternatives. Thanks for your help, Dinh

[Dovecot] Question about quota configuration
by przemek.orzechowski＠makolab.pl 06 Feb '12

06 Feb '12

Hi This is my first post here so i will be as precise as i can I'm trying to setup a quota system using dovecot postfix and procmail dovecot version 1.2.9 postfix version 2.7.0 I have succesfully modified dovecot config to use fs quota system (so far imap and pop3) It reports correct quotas to imap and pop3 clients (both user and group) What im tryin to do now is to modify postfix->procmail->dovecot config in a way that if user is over quota mail delivery is delayed instead of bouncing. (is this possible?) Second thing i would like to achive is that when authenticated users close to quota/group quota for example 10MB to quota limit try sending email theyr mail is rejected and preferably an email is generated telling them to free some space for new mails first. (is such a thing possible?) MS Exchange servers have such a feature and I would like to get such a functionality on my linux mailserver I'm trying to prevent a situation when mails are lost due to quota problems. This setup was initially a typical virtualmin installation with a system on single partition. Thanks in advance for all Your suggestions

[Dovecot] doveadm purge on shared storage
by Jan-Frode Myklebust 06 Feb '12

06 Feb '12

We've finally (!) started to put some users on mdbox instead of maildir, and now I'm wondering about the purge step. As we're running GPFS for the mailboxes (and dovecot director in front of every dovecot service), is it important to run the "doveadm purge -u $user" on the same host as $user is logged into to avoid index corruption ? If so, will we need to run the "doveadm purge" trough the dovecot director as well? -jf

[Dovecot] Sieve notify messages
by Andreas Muehlemann 05 Feb '12

05 Feb '12

Hi All I'm using dovecot 2.0.16 with the pigeonhole plugin 0.25. I'm trying to use the notifiy mechanism from sieve to send notifications when a mail arrives in the mailbox. The message is checked to be a 8bit message, otherwise it is replaced by the default message "Notification of new message." How can I create a 8bit message body within the sieve script that is accepted by the notification process? e.g. notify :message "Subject: ${subject}" "mailto:email@domain.com"; Do I have to put the message body into the :message string? Or how can I define a custom message body that is accepted by notify? Best regards Andreas

[Dovecot] LDAP auth improvements
by Timo Sirainen 03 Feb '12

03 Feb '12

v2.1 supports now multiple LDAP fields in a template e.g.: user_attrs = \ homeDirectory=home, \ uidNumber=uid, \ gidNumber=gid, \ =mail=%{ldap:mailboxFormat}:%{ldap:homeDirectory} which is the same as: user_attrs = \ =home=%{ldap:homeDirectory}, \ =uid=%{ldap:uidNumber}, \ =gid=%{ldap:gidNumber}, \ =mail=%{ldap:mailboxFormat}:%{ldap:homeDirectory} I was also thinking about adding an alternative simplified syntax for this: user_attrs { home = %{ldap:homeDirectory} uid = %{ldap:uidNumber} gid = %{ldap:gidNumber} mail = %{ldap:mailboxFormat}:%{ldap:homeDirectory} } Any ideas for further improvements before I do this change? One thing I'm still wondering about is what I should do when LDAP returns multiple values. Like perhaps: acl_groups = %{ldap:aclGroups:,} Which would mean that all the aclGroups values would be joined together separated by "," characters. And a bit more complex with multiple gidNumbers: gid = %{ldap:gidNumber[0]} mail_access_groups = %{ldap:gidNumber[1:]:,}

[Dovecot] Doubts about dsync, mdbox, SIS
by Jan-Frode Myklebust 03 Feb '12

03 Feb '12

I've been running continous dsync backups of our Maildirs for a few weeks now, with the destination dsync server using mdbox and SIS. The idea was that the destination server would act as a warm copy of all our active users data. The active servers are using Maildir, and has: $ df -h /usr/local/atmail/users/ Filesystem Size Used Avail Use% Mounted on /dev/atmailusers 14T 12T 2.2T 85% /usr/local/atmail/users $ df -hi /usr/local/atmail/users/ Filesystem Inodes IUsed IFree IUse% Mounted on /dev/atmailusers 145M 113M 33M 78% /usr/local/atmail/users very little of this is compressed (zlib plugin enabled during christmas). I'm surprised that the destination server is so large, was expecting zlib and mdbox and SIS would compress it down to much less than what we're seeing (12TB -> 5TB): $ df -h /srv/mailbackup Filesystem Size Used Avail Use% Mounted on /dev/mapper/mailbackupvg-mailbackuplv 5.7T 4.8T 882G 85% /srv/mailbackup Lots and lots of the attachement storage is duplicated into identical files, instead of hard linked. When running "doveadm purge -u $user", we're seeing lots of Error: unlink(/srv/mailbackup/attachments/c3/17/c317b32b97688c16859956f11b803e3bba434349-057274283bb51f4f917e0000bf34f6ab) failed: No such file or directory "/srv/mailbackup/attachments/c3/17/c317b32b97688c16859956f11b803e3bba434349-057274283bb51f4f917e0000bf34f6ab" is missing, but there are 205 other copies of this file named /srv/mailbackup/attachments/c3/17/c317b32b97688c16859956f11b803e3bba434349-* with identical sha1sum. Also we see corrupted indexes during the purge. This makes me quite uncertain if dsync is a workable backup solution.. or if we can trust mdboxes. Also on the source side, during dsync, we see too many problems.

[Dovecot] Feature request - search and tag protocol - notmuch-alike approach
by Kirill A. Shutemov 03 Feb '12

03 Feb '12

Hi all, notmuch[1] becomes more and more popular. At least in geek community. But notmuch is local-only (except ssh)... It looks like it's hard (if even possible) to use IMAP as transport for notmuch-alike work flow. I think it would be great to create a new protocol based global search and message tagging. All core notmuch operations (search, show, count, tag) can be mapped to the new protocol (more or less) directly. Search syntax can be reused as is, I think. The tricky part is initial tagging. It requires some kind of transaction to be able to tag new messages without racing with upcoming messages. Request (command) syntax can be similar to unix command. This way we can reuse notmuch syntax even deeper. Like: search --limit 10 --sort=oldest-first tag:to-me tag:unread Replies are often structured. I think it's reasonable to use JSON for all replies. Any ideas? I've started to write a proof-of-concept, but it moves too slow, since my knowledge of dovecot internals is poor and it's hard to find time for the project. I hope somebody else has similar idea in mind and just wait opportunity to discuss the idea and start to write code. ;) [1] http://notmuchmail.org/ -- Kirill A. Shutemov

[Dovecot] converting from mbox to maildir ?
by Frank Bonnet 02 Feb '12

02 Feb '12

Hello We are planning to convert our mailhub ( freebsd 7.4 ) from mbox format to maildir format. I've read the documentation and performed some tests on another machine it is a bit long ... I would like some feedback from guys who did this operation and need some advice on what to convert first ? - first convert INBOX then convert IMAP folders ? - first convert IMAP folders then convert INBOX ? the machine use real users thru openldap ( pam_ldap + nss_ldap ) another problem is disk space. The users's email data takes about 2 Terabytes of data and I cannot duplicate as I only have 3 Tb on the raid array of the server. My idea is to use one of our NFS netapp filer during the convertion to throw the result of the convertion on an NFS mounted directory. Anyone did this before ? If yes I would be greatly interrested by their experience Thank you

[Dovecot] Renaming user account / mailbox
by Nikolaos Milas 02 Feb '12

02 Feb '12

Hello, I am running dovecot-2.0.13-1_128.el5 x86_64 RPM on CentOS 5.7. All accounts are virtual, hosted on LDAP Server. We are using Maildir mailboxes. The question: What is the process to rename an existing account/mailbox? I would like to rename userx with email: userx(a)example.com to ux(a)example.com with a mailbox of ux (currently: userx) Of course the idea is that new mail will continue to be delivered to the same mailbox, although it has been renamed. How can I achieve it? Would it be enough (after changing the associated data in the associated LDAP entry) to simply rename the virtual user directory name, e.g. from /home/vmail/userx to /home/vmail/ux ? Thanks in advance, Nick

[Dovecot] Site-wide configurable Sieve
by Gedalya 01 Feb '12

01 Feb '12

Hi, I need some sieve actions to be specified per-user, but exposing actual sieve scripts to users is of the question. For example, I need to be able to either put spam messages into a spam folder, or discard them, based on user preference. Presumably this would be done using Sieve. As I understand, it's not possible to query a database from within a sieve script. If I can't use a single global script, I can imagine automatically generating per-user scripts when settings are saved in a GUI (e.g. webmail) and store them on the dovecot machine. This would work but I would love to hear if someone has a smarter, more robust idea. Thanks, Gedalya

[Dovecot] LMTP : Can't handle mixed proxy/non-proxy destinations
by Alexis Lelion 01 Feb '12

01 Feb '12

Hello, In my current setup, I uses two mailservers to handle the users connections, and my emails are stored on a distant server using NFS (maildir architecture) Dovecot is both my IMAP server and the delivery agent (LMTP via postfix) To avoid indexing issues related to NFS, proxying is enabled both on IMAP and LMTP. But when a mail is sent to users that are shared between the servers, I got the subject mentionned error in the logs : Jan 25 09:05:12 mail01 postfix/lmtp[23934]: A92709300DB: to=< user_on_mail02(a)domain.com>, relay=mail01.domain.com[private/dovecot-lmtp], delay=0.07, delays=0.01/0/0/0.06, dsn=4.3.0, status=deferred (host mail01.domain.com[private/dovecot-lmtp] said: 451 4.3.0 < user_on_mail02(a)domain.com> Can't handle mixed proxy/non-proxy destinations (in reply to RCPT TO command)) >From what I saw, the mail is then put in the queue, and wait until the next time Postifx will browse the queue. The mail will then be correctly delivered on "mail02". However, the "queue_run_delay" postfix parameter is set to 900, which means that the mail will be delivered with a lag of 15 minutes. I was wondering if there was another way of handling this, for example by triggering an immediate queue lookup from postfix or forwarding a copy of the mail to the other server. Note that the postfix "queue_run_delay" was increased to 15min on purpose, so I cannot change that. I'm using dovecot 2.0.15 on Debian Squeeze, kernel 2.6.32-5-amd64. Thanks, Alexis

[Dovecot] Issues w/ Apple devices after migration to dovecot
by Armistead, Kurt 01 Feb '12

01 Feb '12

Hi guys. Recently we've moved our old (and I mean _really_ old) mailserver to a new hardware. Since I had quite some time on my hands, I decided to switch from courier to dovecot. Transition went pretty smoothly and the users experienced just a few hours' blackout. Only trouble now is that, after re-configuring some IOS handsets and tablets, not all messages are displayed correctly. For example, I had a long existing mailbox (roughly 1600 emails in INBOX and about a dozen other folders) that showed up perfectly on my iphone. Now it's been synced to the new dovecot server via imap and a whole month of messages seems to be missing. I checked on the server, via webmail and with outlook and everything is where it should be. The problem shows up on Apple devices (same thing happened on a couple of ipads). I haven't tried rebuilding the index or wiping out a phone to see if that resolves the problem, but before I do that I'd like to know if anyone experienced the same issue and how they fixed it Thanks! Kurt

[Dovecot] Uncompressing dboxes
by Lauri Alanko 01 Feb '12

01 Feb '12

Hello. I have an mdbox directory that has been created with the zlib plugin active, using bzip2 compression. I would now like to convert these into uncompressed mdbox format. How do I do this? I have tried unsetting all zlib-related configuration options, but dsync still produces compressed mdbox at the other end, too. I guess I could convert to mbox, and then back to mdbox, but for certain reasons I'm not very enthusiastic about doing anything mbox-related with dovecot any more. (Incidentally, it's a bit funny that when the zlib plugin is enabled, dsync automatically creates compressed dboxes, and even compressed maildirs (which is pretty useless), but not compressed mboxes, although that's where compression would be most beneficial.) Thanks, Lauri

Maybe I don't understand the subtlety of your question, but are you trying to disambiguate between a mounted filesytem and a failed mount that presents the underlying filesystem (which looks like an uninitilized index directory)? Couldn't you write some cookie file "/mount/.../dovecot-data-root/.dovemount", whose existence will tell you whether the FS is mounted without trying to find the mount root. Oh, but then again if you have per-user mounts, that's going to get messy. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Director to keep redirecting users to the same server even after all sessions closed?
by Mark Zealey 30 Jan '12

30 Jan '12

Hi there, Just wondering how easy it would be to make the director continue to send a user to the same server (assuming it's still in the pool) for say 90 seconds after they have last been active (ie lmtp or pop/imap)? Basically we are working in quite a heavily cached environment so it takes perhaps 60-90 seconds for our imap servers to properly flush to our network storage meaning if the user got put on a different server in that time we would see some issues. Presently we have fixed proxying, but I'd really like to use the director if possible to allow us to more easily add & remove servers. Mark

[Dovecot] UID 0 problem while issuing an UID THREAD REFS command
by Jesús M. Navarro 30 Jan '12

30 Jan '12

Hi: This is my first message to this list, so pleased to meet you all. Using dovecot 2.0.17 from packages at xi.rename-it.nl on a Debian "Squeeze" i686. Mail storage is a local ext3 partition (I attached the output of dovecot -n to this message). I'm having problems on a maildir due to dovecot returning an UID 0 to an UID THREAD REFS command: in <== TAG5 UID THREAD REFS us-ascii SINCE 18-Jul-2011 out <== * THREAD (0)(51 52)(53)(54 55 56)(57)(58)(59 60)(61) TAG5 OK Thread completed. The issuer is an atmail webmail that after the previous output will try an UID FETCH 0 that will fail with a "TAG6 BAD Error in IMAP command UID FETCH: Invalid uidset" message. I think that, as per a previous answer from Timo Sirainen*1, this should be considered a dovecot's bug, am I right? Anyway, what should I try to find why is this exactly happening?

[Dovecot] Mountpoints
by Timo Sirainen 30 Jan '12

30 Jan '12

I've been thinking about mountpoints recently. There have been a few problems related to them: - If dbox mails and indexes are in different filesystems, and index fs isn't mounted and mailbox is accessed -> Dovecot rebuilds indexes from scratch, which changes UIDVALIDITY, which causes client to redownload mails. All mails will also show up as unread. Once index fs gets mounted again, the UIDVALIDITY changes again and client again redownloads mails. What should happen instead is that Dovecot simply refuses to rebuild indexes when the index fs isn't mounted. This isn't as critical for mbox/maildir, but probably a good idea to do there as well. - If dbox's alternative storage isn't mounted and a mail from there is tried to be accessed -> Dovecot rebuilds indexes and sees that all mails in alt path are gone, so Dovecot also deletes them from indexes as well. Once alt fs is mounted again, the mails in there won't come back without manual index rebuild and then they have also lost flags and have updated UIDs causing clients to redownload them. So again what should happen is that Dovecot won't rebuild indexes while alt fs isn't mounted. - For dsync-based replication I need to keep a state of each mountpoint (online, offline, failover) to determine how to access user's mails. So in the first two cases the main problem is: How does Dovecot know where a mountpoint begins? If the mountpoint is actually mounted there is no problem, because there are functions to find it (e.g. from /etc/mtab). So how to find a mountpoint that should exist, but doesn't? In some OSes Dovecot could maybe read and parse /etc/fstab, but that doesn't exist in all OSes, and do all installations even have all of the filesystems listed there anyway? (They could be in some startup script.) So, I was thinking about adding doveadm commands to explicitly tell Dovecot about the mountpoints that it needs to care about. When no mountpoints are defined Dovecot would behave as it does now. doveadm mount add|remove <path> - add/remove mountpoint doveadm mount state [<path> [<state>]] - get/set state of mountpoint (used by replication) - if path isn't given list states of all mountpoints List of mountpoints is kept in /var/lib/dovecot/mounts. But because the dovecot directory is only accessible to root (and probably too much trouble to change that), there's another list in /var/run/dovecot/mounts. This one also contains the states of the mounts. When Dovecot starts up and can't find the mounts from rundir, it creates it from vardir's mounts. When mail processes notice that a directory is missing, it usually autocreates it. With mountpoints enabled, Dovecot first finds the root mountpoint for the directory. The mount root is stat()ed and its parent is stat()ed. If their device numbers equal, the filesystem is unmounted currently, and Dovecot fails instead of creating a new directory. Similar logic is used to avoid doing a dbox rebuild if its alt dir is currently in unmounted filesystem. The main problem I see with all this is how to make sysadmins remember to use these commands when they add/remove mountpoints?.. Perhaps the additions could be automatic at startup. Whenever Dovecot sees a new mountpoint, it's added. If an old mountpoint doesn't exist at startup a warning is logged about it. Of course many of the mountpoints aren't intended for mail storage. They could be hidden from the "mount state" list by setting their state to "ignore". Dovecot could also skip some of the common known mountpoints, such as where type is proc/tmpfs/sysfs. Thoughts?

[Dovecot] A namespace error on 2.1rc5
by Bill Ryder 30 Jan '12

30 Jan '12

Hello all, I'm not sure if this is a bug. It's probably just an upgrade note. In summary I had no namespace section in my 2.0.17 config. When trying out 2.1rc5 no user could login because of a namespace error. 2.1rc5 adds a default namespace clause which broke my logins (It was noted in the changelog) I seemed to fix it by just putting this in the config file: namespace inbox { inbox = yes } Long story: I've been recently testing dovecot against cyrus to decide where we should go for our next mail server(s) I loaded up the mail server with mail delivered via postfix all on dovecot 2.0.15 (I've since moved to 2.0.17) I have three dovecot directors, two backends on the same NFS mail store. With dovecot 2.0.xx the tester works fine (it't just a script which logins in and emulates thunderbird when a user is idle - without using IDLE so the client asks for mail every few minutes). When I moved to 2.1rc5 I got namespace errors and the user can not login. The server said: dovecot-error.log-20120128:Jan 27 13:37:59 imap(ethab01): Error: user ethab01: Initialization failed: namespace configuration error: inbox=yes namespace missing The client says: * BYE Internal error occurred.

I rolled back to 2.0.17 and it was fine again.

[Dovecot] imap-login process_limit reached
by Don Buchholz 29 Jan '12

29 Jan '12

I've been having some problems with IMAP user connections to the Dovecot (v2.0.8) server. The following message is being logged. Jan 16 10:51:36 postal dovecot: master: Warning: service(imap-login): process_limit reached, client connections are being dropped The server is running Red Hat Enterprise Linux release 4 (update 6). Dovecot is v2.0.8. We have only 29 user accounts in /etc/dovecot/users. There were 196 "dovecot/imap" processes and 6 other dovecot processes, for a total of 202 "dovecot" processes, listed in the 'ps aux' output when problems were being experienced. Stopping and restarting the Dovecot system fixes the problem -- for a while. The 'doveconf -n' output is attached. I have not set any "process_limit" values, and I don't think I'm getting anywhere close to the 1024 default, so I'm pretty confused as to what might be wrong.

[Dovecot] 2.1.rc1 (056934abd2ef): virtual plugin mailbox search pattern
by e-frog 29 Jan '12

29 Jan '12

Hello Timo, With dovecot 2.1.rc1 (056934abd2ef) there seems to be something wrong with virtual plugin mailbox search patterns. I'm using a virtual mailbox 'unread' with the following dovecot-virtual file $ cat dovecot-virtual * unseen For testing propose I created the following folders with each containing one unread message INBOX, INBOX/level1 and INBOX/level1/level2 2.1.rc1 (056934abd2ef) 1 LIST "" "*" * LIST (\HasChildren) "/" "INBOX" * LIST (\HasChildren) "/" "INBOX/level1" * LIST (\HasNoChildren) "/" "INBOX/level1/level2" * LIST (\HasChildren) "/" "virtual" * LIST (\HasNoChildren) "/" "virtual/unread" 1 OK List completed. 2 STATUS "INBOX" (UNSEEN) * STATUS "INBOX" (UNSEEN 1) 2 OK Status completed. 3 STATUS "INBOX/level1" (UNSEEN) * STATUS "INBOX/level1" (UNSEEN 1) 3 OK Status completed. 4 STATUS "INBOX/level1/level2" (UNSEEN) * STATUS "INBOX/level1/level2" (UNSEEN 1) 4 OK Status completed. 5 STATUS "virtual/unread" (UNSEEN) * STATUS "virtual/unread" (UNSEEN 1) 5 OK Status completed. Result: virtual/unread shows only 1 unseen message. Further tests showed it's the one from INBOX. The mails from the deeper levels are not found. Downgrading to 2.0.16 restores the correct behavior: 1 LIST "" "*" * LIST (\HasChildren) "/" "INBOX" * LIST (\HasChildren) "/" "INBOX/level1" * LIST (\HasNoChildren) "/" "INBOX/level1/level2" * LIST (\HasChildren) "/" "virtual" * LIST (\HasNoChildren) "/" "virtual/unread" 1 OK List completed. 2 STATUS "INBOX" (UNSEEN) * STATUS "INBOX" (UNSEEN 1) 2 OK Status completed. 3 STATUS "INBOX/level1" (UNSEEN) * STATUS "INBOX/level1" (UNSEEN 1) 3 OK Status completed. 4 STATUS "INBOX/level1/level2" (UNSEEN) * STATUS "INBOX/level1/level2" (UNSEEN 1) 4 OK Status completed. 5 STATUS "virtual/unread" (UNSEEN) * STATUS "virtual/unread" (UNSEEN 3) 5 OK Status completed. Result: virtual/unread shows 3 unseen messages as it should The namespace configuration is as following namespace { hidden = no inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace { location = virtual:~/virtual prefix = virtual/ separator = / subscriptions = no type = private } I've also tried this with location = virtual:~/virtual:LAYOUT=maildir++ leading to the same result. Thanks, e-frog

[Dovecot] Migration to multi-dbox and SiS
by Ronald MacDonald 29 Jan '12

29 Jan '12

Dear list, A huge thank-you first of all for all the work that's gone into Dovecot itself. I'm rebuilding a mail server next week and so, taking the rare opportunity to re-consider all the options I've had running over the past couple of years. Around the time of the last re-build (2010), there had been some discussion on single instance storage, which was quite new on Dovecot around then. I chickened out of setting it up though. Now with it having been in the wild for a couple of years, I wonder, how have people found SiS to behave? Additionally, though there was talk of the prospect of it being merged with 2.x am I right in thinking it's not yet in the main project? Couldn't find any 2.x changelogs that could confirm this. With best wishes, Ronald.

[Dovecot] Attribute Cache flush errors on FreeBSD 8.2
by Phil Kernick 29 Jan '12

29 Jan '12

I'm running dovecot 2.0.16 on FreeBSD 8.2 with the mail spool and indexes on an NFS server. Lines like the following keep appearing in syslog for access to each mailbox: Error: nfs_flush_attr_cache_fd_locked: fchown(/home/philk/Mail/Deleted) failed: Bad file descriptor This is coming from nfs-workarounds.c line 210, which tracing back seems to be coming from the call to mbox_lock on lib-storage/index/mbox/mbox-lock.c line 774. I have /home mounted with options acregmin=0,acregmax=0,acdirmin=0,acdirmax=0 (as FreeBSD doesn't have a noac option), but it throws the same error either way. The output of dovecot -n is below.

[Dovecot] compressed mboxes very slow
by kjonca＠o2.pl 29 Jan '12

29 Jan '12

I have some archive mails in gzipped mboxes. I could use them with dovecot 1.x without problems. But recently I have installed dovecot 2.0.12, and they are slow. very slow. Creating index files takes about 10 minutes for ~20M file with 560 messages for bzipped mbox, for gzipped is little better but still unusable :( Stracing dovecot process shows that every ~ 20 messages it rereads complete mbox file. Am I doing something wrong? KJ -- http://modnebzdury.wordpress.com/2009/10/01/niewiarygodny-list-prof-majewsk…

[Dovecot] maildir vs mdbox
by Jean-Daniel Beaubien 29 Jan '12

29 Jan '12

Hi, I am planning on running on test between maildir and mdbox to see which is a better fit for my use case. And I'm just looking for general advice/recommendation. I will post any results I obtain here. Important question: I have multiple users hitting the same email account at the same time. Can be a problem with mdbox? (either via thunderbird or with custom webmail apps). I remember having huge issues with mbox a decade ago because of this. Maildir fixed this... will mdbox reintroduce this problem? This is a very important point for me. Here is my use case: - Ubuntu server (any specific recommandations on FS to use?) - Standard PC hardware (core i5 or i7, few gigs of ram, hdds at first, probably ssd afterwards, nothing very fancy) - Serving only a hand full of email accounts but some of the accounst have over 3 millions emails in them (with individual mail folders having 100k+ emails) - Will use latest dovecot (2.1 when it comes out) - fts-lucene or fts-solr? -jd

Clients aren't supposed to send them. Sorry, apparently I was a bit too fast there. ADDTO and REMOVEFROM should not be sent by a client, but I think that a client can send CONTEXT as a hint to the server, see http://tools.ietf.org/html/rfc5267#section-4.2 Thanks! Regards Anders

[Dovecot] howto disable indexing on dovecot-lda ?
by Adrian Minta 28 Jan '12

28 Jan '12

Hello, is it possible to disable indexing on dovecot-lda ? Right now postfix delivers the mail directly to the nfs server without any problems. If I switch to dovecot-lda the system crashes do to the high I/O and locking. Indexing on lda is not very useful because the number of of imap logins is less than 5% that of incoming mails, so an user could wait for 3 sec to get his mail index, but a new mail can't. Dovecot version 1.2.15 mail_nfs_storage = yes mail_nfs_index = yes Than you !

[Dovecot] where is subscribed list stored?
by Michael Makuch 28 Jan '12

28 Jan '12

I'm using $ /usr/sbin/dovecot --version 2.0.15 on $ cat /etc/fedora-release Fedora release 14 (Laughlin) and version 8 of Thunderbird. I use dovecot locally for internal only access to my email archives, of which I have many gigs of email archives. Over time I end up subscribing to a couple dozen different IMAP email folders. Problem is that periodically my list of subscribed folders get zapped to none, and I have to go and re-subscribe to a dozen or two folders again. Anyone seen this happen? It looks like the list of subscribed folders is here ~/Mail/.subscriptions and I can see in my daily backup that it reflects what appears in TBird. What might be zapping it? I use multiple email clients simultaneously on different hosts. (IOW I leave them open) Is this a problem? Does dovecot manage that in some way? Or is that my problem? I don't think this is the problem since this only occurs like a few times per year. If it were the problem I'd expect it to occur much more frequently. Thanks for any clues Mike
