[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. It's the same config files for both, same maildirs etc etc. All I did was change the dovecot version from 2.0.17 to 2.1rc5 However I see from the changelog that 2.1rc5 added a default namespace inbox: diff doveconf-n.2.0.17 doveconf-n.2.1-rc5 1c1 < #

[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

Hi Timo, the attached patch seems to solve a warning from autoconf: libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.in and libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree. Best regards, Luca

[Dovecot] Password auth scheme question with mysql
by Ed W 28 Jan '12

28 Jan '12

Hi, I have a current auth database using mysql with a "password" column in plain text. The config has "default_pass_scheme = PLAIN" specified In preparation for a more adaptable system I changed a password entry from "asdf" to "{PLAIN}asdf", but now auth fails. Works fine if I change it back to just "asdf". (I don't believe it's a caching problem) What might I be missing? I was under the impression that the password column can include a {scheme} prefix to indicate the password scheme (presumably this also means a password cannot start with a "{"?). Is this still true when using mysql and default_pass_scheme ? Thanks for any hints? Ed W

[Dovecot] dovecot imap cluster
by Matteo Cazzador 28 Jan '12

28 Jan '12

Hello, i'm using postfix like smtp server, i need to choose an imap server with a special features. I have a customer with 3 different geographic locations. Every locations have a mail server for the same domain (example.com) If user1(a)example.com receive mail form external this mail going on every locations server. I've a problem now, is it possible to syncronize the state (mail flag) of user1 imap folder mails on every mail locations server? Example, if user1 read a mail on server one is it possible to change flag of the same mail file on server 2 and server 3? Is it possible to use dsync for it? I need something like imap cluster. Or an action in post processing imap mail read. I can't use distribuited file system. Thank's a lot -- Rispetta l'ambiente: se non ti è necessario, non stampare questa mail. ****************************************** Ing.

[Dovecot] v2.1.rc5 released
by Timo Sirainen 27 Jan '12

27 Jan '12

http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc5.tar.gz http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc5.tar.gz.sig I'm still lagging behind reading emails. v2.1.0 will be released after I've finished that. RC5 is already stable and used in production, but I want to make sure that I haven't missed anything important that was reported previously. Most of the recent fixed bugs existed also in v2.0 series. Changes since rc3: * Temporary authentication failures sent to IMAP/POP3 clients now includes the server's hostname and timestamp. This makes it easier to find the error message from logs. + auth: Implemented support for Postfix's "TCP map" sockets for user existence lookups. + auth: Idling auth worker processes are now stopped. This reduces error messages about MySQL disconnections. - director: With >2 directors ring syncing might have stalled during director connect/disconnect, causing logins to fail. - LMTP client/proxy: Fixed potential hanging when sending (big) mails - Compressed mails with external attachments (dbox + SIS + zlib) failed sometimes with bogus "cached message size wrong" errors. (I skipped rc4 release, because I accidentally tagged it too early in hg.)

Re: [Dovecot] auth-worker temporary failures causing lmtp 500 rejection
by Mark Zealey 26 Jan '12

26 Jan '12

Hi Timo thanks for the patch; I have now analyzed network dumps & discovered that the cause is actually our frontend mail servers not dovecot - we were delivering to the wrong lmtp port which we then use in the mysql query hence getting empty records. Sorry about this! Mark ________________________________________ From: Mark Zealey Sent: 26 January 2012 14:37 To: Timo Sirainen Cc: dovecot(a)dovecot.org Subject: RE: [Dovecot] auth-worker temporary failures causing lmtp 500 rejection I've tried reproducing by having long running auth queries in the sql and KILLing them on the server, restarting the mysql service, and setting max auth workers to 1 and running 2 sessions at the same time (with long-running auth queries), but to no effect. There must be something else going on here; I saw it in particular when exim on our frontend servers had queued a large number of messages and suddenly released them all at once hence the auth-worker hypothesis although the log messages do not support this. I'll try to see if I can trigger this manually although we have been doing some massively parallel testing previously and not seen this.

Is this an issue with the code or perhaps some setting I have missed? The problem is that temporary errors are returning "unknown user". Can you reproduce this somehow? Like if you stop MySQL it always returns that "Unknown user"?

[Dovecot] auth-worker temporary failures causing lmtp 500 rejection
by Mark Zealey 26 Jan '12

26 Jan '12

Hi there, I'm using dovecot 2.0.16 with a mysql user database. From time to time when we have a big influx of messages (perhaps more than 30 concurrent rcpt to:<> sessions at the same time so no auth-workers free?) or when we have a transient issue connecting to the database server, we see the message: Jan 25 16:38:23 mailbox dovecot: auth-worker: sql(foo(a)bar.com,1.2.3.4): Unknown user and the lmtp process returns: 550 5.1.1 <foo(a)bar.com> User doesn't exist: foo(a)bar.com This would be correct for a permanent error where the user doesn't exist in our database, however it seems to be doing this on transient errors too. Is this an issue with the code or perhaps some setting I have missed? Thanks, Mark

[Dovecot] Persistence of UIDs
by Jean-Daniel Beaubien 26 Jan '12

26 Jan '12

Hi everyone, I have a question concerning UIDs. How persistant are they? I am thinking about building some form of webmail specialized for some specific business purpose and I am thinking of building a sort of cache in a DB by storing the email addr, date, subject and UID for quick lookups and search of correspondance. I am doing this because I am having issue with multiple people searching thru email folders that have 100k+ emails (which is another problem in itself, searches don't seem to scale well when folder goes above 60k emails). So to come back to my question, can I store the UIDs and reuse those UIDs later on to obtain the body of the email??? Or can the UIDs change on the server and they will not be valid anymore?. My setup is: - dovecot 1.x (will migrate to 2.x soon) - maildir - everything stored on an intel 320 SSD (index and maildir folder) Thanks, -JD

Dear Sir, Thanks for your reply and I really agreed your point about 'reject mail for users over quota', but I don't want to do it if it is possible to without reject mails to deliver mails from spool to user's home directory automatically, kindly provide solution.

[Dovecot] FOSDEM
by Timo Sirainen 26 Jan '12

26 Jan '12

I'll be in FOSDEM giving a small lightning talk about Dovecot: http://fosdem.org/2012/schedule/event/dovecot I'll also be around in FOSDEM the whole time, so if you're there and want to talk to me about anything, send me an email at some point. Poll to dovecot-news list people: Do you want to see these kind of news about my upcoming talks sent to the list? Probably happens a few times/year. A simple "yes" or "no" reply to this mail privately to me is enough.

[Dovecot] Dovecot antispam plugint got an empty message
by Petr Bravenec 25 Jan '12

25 Jan '12

Few weeks ago I upgraded dovecot from 1.2 to 2.0.16 and antispam plugin to 2.0_pre20101222. Since the upgrade I'm not able to move messages to my Junk folder. In the maillog I have found this message: dspam[25060]: empty message (no data received) Message is copied from my INBOX to Junk folder, but dspam got an empty message and sent an error return code. So the moving operation is not successfull and the original message in INBOX was not deleted. The dspam was not trained (got an empty message). Looking to source code of dspam and antispam plugin I suspect the dovecot not to sending any content to plugin. Can you help me, please? Petr Bravenec
