[Dovecot] Unexplained MDA bounce backs
by Dean Manners 14 Jan '08

14 Jan '08

I have recently noticed that some of our internal mailer scripts are causing Dovecot-LDA to generate Mailer Delivery Subsystem messages. The following Dovecot-LDA message is generated: ---- Message body ---- Your message was automatically rejected by Dovecot Mail Delivery Agent. The following reason was given: Unknown error ---- Message body ---- ---- Message header ---- Return-Path: <MAILER-DAEMON> Delivered-To: bounces@xxxxx Received: by mymachine.xxxxx (Postfix, from userid 5000) id 5772568300; Mon, 14 Jan 2008 18:00:56 +1100 (EST) Message-ID: <dovecot-1200294055-774265-0@mymachine> Date: Mon, 14 Jan 2008 18:00:55 +1100 From: Mail Delivery Subsystem <noreply@xxxxx> To: <bounces@xxxxx> MIME-Version: 1.0 Content-Type: multipart/report; report-type=disposition-notification; boundary="21506/mailfilter02" Subject: Automatically rejected mail Auto-Submitted: auto-replied (rejected) Precedence: bulk ---- Message header ---- Initially I thought these were being caused by Delivery-Receipt requests, however have since tested this and is not the case. I have tried to snoop through the logs (unfortunately on a very busy mail hub) using the Message-ID, however this doesn't seem to lead me back to the original message - only the MDA notification. I can only ascertain that its isolated to our scripts, as the bounces@ address is specifically used by them. Any ideas what would cause/trigger the "Unknown error" automatic rejects ? System config is -Postfix 2.3.4 with MySQL backend -Dovecot 1.0.rc26 with MySQL backend, using only deliver. All mail deliveries are otherwise fine.

Re: [Dovecot] Imap proxy with tls?

offlineimap looks like it will work. Do you know if it works well on big changes? I have about 1.5 gigs of email at the local site that will need to be uploaded to the main server. After its uploaded it will have to weed through it all during the sync every time. Think that will be ok?

[Dovecot] Imap proxy with tls?
by Someone Something 14 Jan '08

14 Jan '08

Hello all, I have a server with dovecot installed with imap and tls working (call that the remote server). Now I want to have a few computers at the same place to access the same account on the remote server. I have another server (call this the local server) at the local site to do this with but am not sure how to do it. The proxy setup http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy looks about right but that does not seem to support tls? I need tls going from the local server to the remote server. I want all emails on the remote server to be the same as on the local server. This way all clients at the local site have very fast access to email and can still get to the email when not at the local site. Any suggestions? Thanks

[Dovecot] Indexes

When something "bad" happens to the indexes, my e-mail client (Thunderbird) reports an "unable to succeed" error on opening a mailbox. Leaving that mailbox and coming back works fine. Is this expected behaviour? -- Daniel

[Dovecot] Custom 'quota exceeded' message + Sieve script from database
by Przemyslaw Wegrzyn 13 Jan '08

13 Jan '08

Hi! I'm quite new to Dovecot. helping my friend to migrate from Courier-IMAP to something more efficient, we are evaluating Dovecot at the moment. I had to prepare 2 small patches for Dovecot to suit our needs, and I've decided to post it here. I'm not fully familiar with Dovecot architecture yet, I'd appreciate if someone could look if these changes make sense (i.e. doesn't break anything). And of course, maybe someone is interested as well. 1. Customized "quota exceeded" message. http://czajnick.sitenet.pl/dovecot/dovecot_1.0.9_quota_exceeded_message.diff - quick hack to let me define custom message instead of typical "Quota exceeded", simply by using plugins { quota_exceeded_message = ... }. Browsing this mailing list I've seen some posts about such feature being implemented in Dovecot. Is it done in a similar way? Which stable version is the first to include this functionality? 2. Sieve filter modification http://czajnick.sitenet.pl/dovecot/dovecot_sieve_1.0.2_envscript_patch.diff In our systems we currently use a modified maildrop MDA that picks the filter script from the database instead of the file. This has proven useful - end-user's administration panel doesn't need any special permissions (or networking capabilities), as it doesn't need to access the filesystem - it is reduced to a plain database web-app. The patch above makes the delivery agent check for the sieve script present in SIEVE_SCRIPT environment variable. If this is the case, env var content is used instead of the script stored in a usual file pointed to by SIEVE variable. This makes it trivial to pass the script from the database using base dovecot functionality. A minor drawback of such solution is that the script is re-compiled on each delivery, but I don't think it takes much time to compile a few lines of a script using (f)lex/bison-or-yacc parser. Yes, I've noticed the sieve-manage patch, but I don't want the complexity of managing sieve script over the socket connection (if my understanding of the script is wrong, please correct me). BR, Przemyslaw

[Dovecot] do not lose mail when dovecot is dead
by Daniel 13 Jan '08

13 Jan '08

Hi! Recently I've experienced problems with dovecot. Dovecot died silently, what means is that there are no core files, nor any indication in the log files, just the "kevent(): Invalid argument" messages. Dovecot just died, so deliver could not connect to the auth-master socket, which means that messages couldn't been delivered. The problem is that postfix thought that the delivery was successful, and didn't place the message to delay, but deliver(LDA) couldn't deliver the message, so it got lost. An example: postfix/pickup[29619]: 8A1C6F261: uid=1001 from=<id> postfix/cleanup[19148]: 8A1C6F261: message-id=<20080107192402.8A1C6F261(a)domain.hu> postfix/qmgr[29441]: 8A1C6F261: from=<id(a)domain.hu>, size=585, nrcpt=1 (queue active) deliver(leva): Loading modules from directory: /usr/local/lib/dovecot/lda deliver(leva): Module loaded: /usr/local/lib/dovecot/lda/lib10_quota_plugin.so deliver(leva): Module loaded: /usr/local/lib/dovecot/lda/lib90_cmusieve_plugin.so deliver(leva): Can't connect to auth server at /var/run/dovecot/auth-master: Connection refused postfix/pipe[8582]: 8A1C6F261: to=<leva(a)domain.hu>, orig_to=<id>, relay=dovecot-lda, delay=1.7, delays=1.1/0/0/0 .68, dsn=2.0.0, status=sent (delivered via dovecot-lda service) postfix/qmgr[29441]: 8A1C6F261: removed See? Postfix removed it from the queue, so basically all bets are off, and everything depends on deliver, but it just dropped the message. Is there anything that can be done regarding this issue? Thanks! Daniel

[Dovecot] randomly disconnected with imap, and latest hg
by Daniel 12 Jan '08

12 Jan '08

Hi! I'm using latest hg from the 1.1 branch, and noticed that since yesterday's updates, dovecot randomly disconnects clients when using imap, with these message in the log: "Disconnected for inactivity in reading our output bytes=153/41319" This happens randomly. Eg. I'm fetching messages, and suddenly, dovecot disconnects. Or my MUA just sits there, and then again, dovecot disconnects me with this message. I didn't even do anything with the client, so I can't think of anything which could've been read. What could be the problem? Daniel

[Dovecot] Please help me resolve why mail isn't being delivered to virtual users
by Andrew Falanga 12 Jan '08

12 Jan '08

Hi, I have to admit that I'm not quite sure why no one has responded to me about this one. If I'm not providing enough information or incorrect information please tell me. It's quite important that this e-mail system be working. I do not quite understand what it is that I'm missing now. I have the need to setup and configure various users as virtual users. To this end, I've configured them so that their home directories are "/virtusers/<userid>" and their INBOXes are "/var/mail/<userid>." I have created a system user ID called "vmail" which is referenced in my PostgreSQL database for UID/GID stuff. All virtual user home directories and INBOXes are made owner "vmail" and group is "users." Originally, I had my sendmail "/etc/mail/aliases" file setup to "map" all mail sent to these virtual users to the system user "vmail." However, none of the virtual users were getting any mail and vmail was just getting swamped. After doing more digging, I found that I just didn't understand the home directories and INBOX, mbox and such. That's what drove me to configuring what's in there now. Now, following directions on this WIKI page: http://wiki.dovecot.org/LDA/Sendmail?highlight=%28deliver%29 I'm still unable to get the e-mail working for them. Continually, sendmail bails with errors saying it, "Can't create output." Because I am using *.mc files, I made a new *.m4 file as directed in /usr/share/sendmail/cf/mailer. Dovecot does allow the virtual users to login. In fact, when I did, the first time, there appears a "mail" directory in their home directories after login. This would indicate to me that the login was successful. Further, I cut/pasted a message sent to one of the virtual users from the vmail INBOX (/var/mail/vmail) into the virtual user's INBOX (/var/mail/jdunkin). Then, logged in as this virtual user and ACTUALLY got the mail. I know this stuff works. What must be done to make sendmail do its thing for deliver? What is necessary to fix this situation? Andy

[Dovecot] Dovecot-imap, tls, gnus
by Richard G Riley 11 Jan '08

11 Jan '08

I have a connection to my dovecot server from gnus: ,---- | (add-to-list 'gnus-secondary-select-methods | '(nnimap "hermes" | (nnimap-stream starttls) | (nnimap-address "hermes") | (nnimap-authinfo-file "~/.authinfo"))) `---- If I enter a group and read my mail then wander off and come back after a few minutes I can not navigate out of the group because my nnimap session has ended. What config parameter do I need to change in Dovecot to keep it open for the life of the client? (I am assuming its a dovecot issue here since it didn't happen with courier-imap).

[Dovecot] Automatically subscribe to folder?
by Christian Flothmann 11 Jan '08

11 Jan '08

Hello everybody, i am filtering e-mails using the cmusieve-plugin. A global script filters all mails tagged by SpamAssasin and moves them into the folder Spam: if header :is "X-Spam-Flag" "YES" { fileinto "Spam"; } My problem is that users who did not had a folder Spam until the first time of filtering a spam mail are not automatically subscribed to this new created folder. They have to do this step manually in their mail client. Is it possible to automate this script and subscribe the account to this folder when it is created by the sieve script? Regards, Christian

[Dovecot] Test Environment Question
by Stewart Dean 11 Jan '08

11 Jan '08

I have my master IMAP server running DC V1.0.10. The homedir and INBOXdir are physically resident there and NFS exported (no caching) to 3 other machines. I have installed V1.1beta13 on one of them (which thus accesses the homedir/INBOXdir remotely) and plan to have a limited community test-drive it there. Are there any hazards or drawbacks in doing this? While the homedirs and INBOXdirs are thus shared, I have it so that each machine has its own local index directory and /var/run dir. Comments or dire warnings?

[Dovecot] virtual domains/users and LDAP
by Anil 11 Jan '08

11 Jan '08

I have two suffixes in LDAP with users, e.g. ou=People, o=example.com ou=People, o=somethingelse.com I have the following two users: dn: uid=test1, ou=People, o=example.com uid: test1 mail: test(a)gmail.com dn: uid=test2, ou=People, o=somethingelse.com mail: test(a)yahoo.com uid: test2 The users login to IMAP as: test1(a)examle.com and test2(a)somethingelse.com. Here's an (excerpt) of the dovecot.conf file I am using: auth_bind = yes base = ou=People,o=%d scope = onelevel pass_attrs = mail=user pass_filter = (uid=%n) userdb static { args = uid=vmail gid=vmail home=/var/mail/apps/%d/%n } The problem I am seeing when the user logs in, the home dir is getting created incorrectly: Jan 3 14:08:12 vds5 dovecot: [ID 107833 mail.info] imap-login: Login: user=<test(a)gmail.com>, method=PLAIN, rip=, lip= Jan 3 14:08:12 vds5 dovecot: [ID 107833 mail.info] IMAP(test(a)gmail.com): Effective uid=500, gid=500, home=/var/mail/apps/gmail.com/test Jan 3 14:08:12 vds5 dovecot: [ID 107833 mail.info] IMAP(test(a)gmail.com): maildir: data=/var/mail/apps/gmail.com/test/Maildir ... I was expecting it to create the home dir under: /var/mail/apps/example.com/test1, since that is what they are logging in with. Any ideas? I am actually surprised that it even let me login with this configuration, something looks odd in this setup. :) Thanks, Anil

[Dovecot] Problems with AUTH=PLAIN in pop3
by Maykel Moya 11 Jan '08

11 Jan '08

I'm using Dovecot (1.0.10) locally to test SugarCRM. When I tried to set up a mail account in Sugar, it complains with -- SECURITY PROBLEM: insecure server advertised AUTH=PLAIN Please check your settings and try again. -- don't know if that behaviour is a bug or a feature of php-imap. The case is that I'm unable to set up the mail account in Sugar. Timo answered to me on IRC about Dovecot assuming that a connection from the same ip is considered secured. I'd rebuild Dovecot with the following patch: --- dovecot-1.0.10/src/pop3-login/client.c.orig 2008-01-05 00:44:14.000000000 -0500 +++ dovecot-1.0.10/src/pop3-login/client.c 2008-01-05 00:44:30.000000000 -0500 @@ -331,7 +331,7 @@ client->created = ioloop_time; client->refcount = 1; client->common.tls = ssl; - client->common.secured = ssl || net_ip_compare(ip, local_ip); + client->common.secured = ssl; client->common.local_ip = *local_ip; client->common.ip = *ip; --- but still not able to make it not accept AUTH PLAIN authentication from the same ip. I'm missing something? On the other hand, if I set disable_plaintext_auth to yes I cannot use the classic USER/PASS pop3 verbs. I'm not sure what the POP3 related RFCs mandates with respect to this.

[Dovecot] Switch from courier to dovecot
by Richard G Riley 10 Jan '08

10 Jan '08

I have an courier IMAP server running. To get sib dirs working I had to rename them all to begin with a period ".". e.g Maildir Maildir/{cur,new,tmp} Maildir/.account1/{cur,new,tmp} Maildir/.account2/{cur,new,tmp} Maildir/.account3/{cur,new,tmp} etc If I uninstall Courier and install dovecot, will these "period" dirs be seen by default? I am fairly new to this and sometimes it seems that Maildir format requirements vary a lot depending on client or server. Thank you for your help.

[Dovecot] OT: ctimes
by Jeff Grossman 10 Jan '08

10 Jan '08

I am going to convert my 32-bit Debian system to a 64-bit Debian system today. But, after I move my maildir files over to the new hard drive the ctimes are going to get modified to current time and mess up my automatic purge scripts for the Deleted Items folders. Is it possible for me to either keep the existing ctimes or is it possible for me to modify the ctimes to the date headers of the emails after I move the files? Thanks, Jeff

[Dovecot] Dovecot indexing questions
by Asheesh Laroia 10 Jan '08

10 Jan '08

I was playing with Dovecot 1.1 full text indexing through Squat in late October, which was working pretty well. I wanted to ask about this behavior I had: When an email arrives in INBOX using procmail (which delivers to my Maildirs), and I see it in Dovecot, when I next do a search (IMAP SEARCH TEXT) of that folder, the search takes a long time. Successive searches are lickety-split. My question is: Can there be an option to "index greedily"? As soon as Dovecot sees the message, I'd like it to update the Squat index. That way, searches are always fast. I guess this implies a small performance hit - namely, that my IMAP server spends CPU and disk time indexing every message at the first time it is seen rather than being able to do batch indexing each time SEARCH TEXT is issued. But when I think about that, that sounds like the server can waste its time so I don't waste mine - which is exactly why I like these computing machines! (That, and because I can waste my time programming them.) -- Asheesh. -- Use extra care when cleaning on stairs.

[Dovecot] Logging to stderr
by Abhijit Hoskeri 10 Jan '08

10 Jan '08

Hi, I am having a bit of a problem with logging to stderr. I am trying to run dovecot as sort of "inetd" install using daemontools. I have daemontools 'services' named dovecot-pop3, dovecot-imap, etc. The service command line looks like tcpsvd -c20 -v -l 0 0 110 /usr/lib/dovecot/pop3-login [--ssl] In dovecot/dovecot.conf, the log_path is set to /dev/stderr. What seems to be happening is that all the log lines (regardless of service) go to the log file of which ever service was first used. Exactly how are these logs written? Is it possible to (easily) make the login process write to its own stderr? Thanks, -Abhijit

[Dovecot] Sendmail, procmail, dovecot and quota
by papi mac 10 Jan '08

10 Jan '08

I have Fedora 7 from a standard installation running sendmail, procmail and dovecot 1.0 installed on a single partition. I now need to set up mail quotas for most of the users but not all. Just protecting /var/spool/mail/$LOGNAME is probably good enough for me. Since I just want mail quotas and the installation is on just 1 partition I don't have an easy way to use file system quotas. By reading through the dovecot documentation and list archives I have the feeling that this is possible with the versions and setup I have. I would probably need a main line like this (apart from other lines) per user mailbox that needs to be managed: dirsize:/var/spool/mail/joe-user:storage 10240 to give joe-user a 10 mb limit. Since this server is in production I don't have the luxury of experimenting (extensively) on it. I have a question though that I have not been able to answer yet. If the flow of mail goes from sendmail to procmail to the mailbox, how is it possible for dovecot to implement quotas on the inbox? Or would dovecot write something there that procmail has to honor? Is dovecot the way to do this? Am I misunderstanding what "quotas" mean in dovecot? Thanks for any clues. --------------------------------- Looking for last minute shopping deals?

[Dovecot] (somewhat ot?) purging old maildir messages
by Matt LaPlante 08 Jan '08

08 Jan '08

I'm using Dovecot (+postfix) to host some personal imap accounts on a private server (Maildir format). I've got one account that receives mostly automated mails, and I want to be able to purge messages beyond a given date (say 30 days). I know that since maildir uses flat files, I can literally just delete messages doing something similar to the following with bash: for i in $(find /var/spool/vmail/host1/user/cur/ -mtime +30); do rm $i done I dislike this approach for a few reasons. First, and most plainly, it seems crude. When running complex server software, its rarely a good idea in the field of systems administration to be bluntly deleting files out from under the running applications. It feels wrong. How does this affect dovecot's monitoring of the files and indexing? What if the files happen to be open in an email client? Etc. Emotions aside, I also very much dislike running an automated 'rm' that has the power to wipe out a lot of my email if something goes pearshaped with the script. I can think of several possible solutions that don't require subversive operations on the maildirs, but I've never used them and therefore don't know if they're actually feasible: - Use a tool designed to manipulate maildirs. Something akin to postfix's postqueue and postsuper tools come to mind, but I don't know if such an app exists. - Use a setting within dovecot that expires old maildir data. As I understand it this will be available in 1.1 (yay!); unfortunately that's not an option for me until 1.1 is available as stable in my server os. - Use a scriptable mua that has the capability to check mail under said account and automatically delete based on age. I know very little of tools in this area, so again I don't know if such an application exists. Any pointers you might have would be much appreciated. Thanks, Matt

[Dovecot] Problem with passwords surrounded by curly braces
by Frank Kintrup 08 Jan '08

08 Jan '08

Hello, one of my users set his password to something surrounded by curly braces, and promptly all access to his mailbox was refused. After looking through the logs I found an entry "Unknown password scheme xxxx", where "xxxx" is the user's password, but without the curly braces. I then browsed through the documentation and there was explained that it is possible to prefix the password with the password scheme in curly braces, like "{PLAIN}xxxx" where xxxx is the password itself. Manually altering the users password in the database to "{PLAIN}xxxx" (where "xxxx" is the user's password WITH curly braces) fixed this problem for me at this time, but the time a user chooses such a strange password I would have to edit the table again. So in my opinion the {SCHEME}-prefix is not a useful thing. Why would anyone need it, anyway? Shouldn't all passwords have the same scheme which is set in the dovecot.conf file once? If the feature is indeed used: with a database lookup it should be replaced by an optional database field or, if that's not possible, it should be possible to disable this feature from the config file.

[Dovecot] What would you tell the CIO in an "ABCs of Email" overview?
by Esther Schindler 07 Jan '08

07 Jan '08

One of the key points that came up when I researched and wrote the "Five Things CIOs Should Know about Fighting Spam" article (http:// www.cio.com/article/28830) was that they should know the basics of how email works. Otherwise, said plenty of techies, the CIO won't have the first idea of what the email admin is complaining about. So I'm going to do my part. I'm going to write an "ABCs of Email" article (to accompany the many other ABCs articles we have on CIO.com, at http://www.cio.com/article/40242 ). I'd like your input on the topics that should be included, keeping in mind the fact that the target reader is a CIO, IT manager, or someone who wants to understand the basics, *not* actively get involved in email management. You don't need to write an essay for me or inundate me with links (though hey, if you want to make my life easier I shall not complain). What I'm looking for, primarily, are the categories of information that I should cover. In other words, if your CIO had an email ephiphany and asked you to give a half-hour presentation, what would you include? This won't be an "Expert says..." article nor will it be "Geek on the street says...." I intend to compile and research the "least you need to know" for the not-necessarily-techie bosses out there. And hopefully the end result will be that you have one less dumb question to deal with in your life. So: any suggestions? (You can reply privately if you prefer.)

06 Jan '08

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta13.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta13.tar.gz.sig Changes since beta12: - Half of LDAP code was rewritten to fix reconnect/queuing problems. I did test that the new code works with and without auth binds, but be careful. - \Recent flags should finally work correctly with maildir. - last_used field wasn't updated for cache fields that were permanently cached. This caused them to be dropped after a month. TODO for RC1: - When pipelining commands, do only one sync after all of them. Besides improving performance, this fixes some rare problems when multiple commands are running simultaneously. - SEARCH/SORT: Replace invalid input with unicode "replacement character" instead of just skipping it. - Squat: Handle expunges. NFS support. - Fix Lucene support.

[Dovecot] deliver fails - RFE
by Anil 06 Jan '08

06 Jan '08

deliver has suid: -rwsr-xr-x 1 root root 1892044 Jan 5 19:21 deliver Jan 5 23:11:02 vds5 deliver(admin(a)domain.com): [ID 702911 mail.error] stat(/var/mail/apps/domain.com/admin/Maildir/tmp) failed: Permission denied The above mentioned directory has these permissions: drwx------ 3 vmail vmail 3 Jan 5 19:15 /var/mail/apps drwx------ 3 vmail vmail 3 Jan 5 19:15 /var/mail/apps/domain.com drwx------ 3 10001 10001 3 Jan 5 19:25 /var/mail/apps/domain.com/admin drwx------ 6 10001 10001 9 Jan 5 23:05 /var/mail/apps/domain.com/admin/Maildir/ drwx------ 2 10001 10001 2 Jan 5 19:03 /var/mail/apps/domain.com/admin/Maildir/tmp It seems deliver needs the /var/mail/apps and the /var/mail/apps/domain.com to be 755. Can Dovecot do this automatically when it creates these directories? (/var/mail/apps, /var/mail/apps/domain.com)

[Dovecot] Upgrading a live running dovecot - how?
by Daniel Watts 06 Jan '08

06 Jan '08

Hi Guys, This has bitten us twice now. We're running Gentoo and emerge (ie compile) a new version of Dovecot thinking we can finish that then restart Dovecot in our own time. It seems that Dovecot immediately starts to use the newly compiled Dovecot binary and we get version mismatch errors preventing access. Would be good if Dovecot behaved in such a way that it kept on using the old version (held in memory) until it was restarted where it then loaded the new version. Dan

[Dovecot] running imap command line
by Anil 06 Jan '08

06 Jan '08

I am trying to debug some core dump problems. I should be able to run imap by itself right? How to fix? # ./imap imap(root): Fatal: setgroups() failed: Too many extra groups I am using latest nightly code.

[Dovecot] How to use deliver to deliver to virtual users
by Andrew Falanga 05 Jan '08

05 Jan '08

Hi, Ok, here's my setup, each virtual user has a home directory as follows: /virtusers/<v_userid> and per the INBOX directive in the dovecot.conf file I also have a file as follows: /var/mail/<v_userid> Now, I've followed the directions as outlined here: http://wiki.dovecot.org/LDA/Sendmail But every time I send mail to one of my virtual users, I get this message The original message was received at Sat, 5 Jan 2008 14:22:51 -0700 (MST) from wa-out-1112.google.com [209.85.146.183] ----- The following addresses had permanent fatal errors ----- /var/mail/jdunkin (reason: Can't create output) (expanded from: <jdunkin(a)whitneybaptist.org>) ----- Transcript of session follows ----- 550 5.0.0 /var/mail/jdunkin... Can't create output What could I be missing? Andy

[Dovecot] help using sendmail LDA
by Anil 05 Jan '08

05 Jan '08

I am stuck. I get nothing in the logs (about deliver). Sendmail complains about "User unknown". I am not sure I have my sendmail.mc configured right, can someone confirm or give me some sample config files that make use of Dovecot+LDAP and sendmail LDA? Dovecot is running as root. I am a little confused, so the auth-master is not even needed? (the whole socket listen {}, since I am using static userdb and the user information was already found at authentication/login) Thank You! # 20080102: /usr/local/dovecot/etc/dovecot.conf listen: *:143 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/dovecot/var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/imap-login login_log_format_elements: user=<%n@%d> method=%m rip=%r lip=%l %c login_max_connections: 64 max_mail_processes: 128 mail_location: maildir:~/Maildir mail_debug: yes auth default: verbose: yes debug: yes passdb: driver: ldap args: /usr/local/dovecot/etc/dovecot-ldap.conf userdb: driver: static args: uid=vmail gid=vmail home=/var/mail/apps/%d/%n socket: type: listen master: path: /var/run/dovecot-auth-master mode: 384 user: vmail group: vmail My sendmail.mc file: define(`confFALLBACK_SMARTHOST', `mailhost$?m.$m$.')dnl define(`LOCAL_MAILER_PATH',`/usr/local/dovecot/libexec/dovecot/deliver') define(`LOCAL_MAILER_FLAGS',`DFMPhfnu9') define(`LOCAL_MAILER_ARGS',`deliver -d $u') MAILER(`local')dnl MAILER(`smtp')dnl LOCAL_NET_CONFIG R$* < @ $* .$m. > $* $#esmtp $@ $2.$m $: $1 < @ $2.$m. > $3

[Dovecot] FETCH for mailbox INBOX UID 39641 got too little data: 4823 vs 4825
by Mikhail Teterin 04 Jan '08

04 Jan '08

Whenever I try to access an e-mail in the middle (rather than at the end) of the mailbox, my mail-client (KMail) gets an error a message like this is logged in the maillog: IMAP(mi): FETCH for mailbox INBOX UID 39641 got too little data: 4823 vs 4825 IMAP(mi): Disconnected: Disconnected The actual numbers vary, but it is always X vs X+2 The problem started when I upgraded to 1.0.8. Unfortunately, it is still here with 1.0.9. The mailbox in question is the standard Unix mbox (/var/mail/mi in my case). The server runs FreeBSD/amd64. Please, advise. Thanks! -mi
