[Dovecot] Caching passwords?
by Hein Celliers 03 Dec '06

03 Dec '06

Hi all! I need some help....changing passwords....... Dovecot server, appears to cache the old credentials. It only discovers the change upon a restart. I need to know how to configure dovecot (dovecot-1.0-0.beta2.7) as not to cache the passwords. (Using fedora core 5) Thanks Hein Celliers

Re: [Dovecot] dovecot:IMAP(user) killed with signal 6

Thanks Timo! Since I've been running rc10 again dovecot stopped aborting. By the way, when I used the create_shares.pl script, it created a symlink for every file in the directory to be shared. Simple symlinking the dir seemed to 'almost' work but for the keyword file errors. Upgrading to rc15 fixes the problem as well, the Permission Denied message still comes up, but dovecot no longer aborts. Will try the create_shares.pl script again and see where my symlink-config is wrong. FWIW I wouldn't want any undocumented behaviour in dovecot just because I'm a stupid twat... Kind regards, Spil.

[Dovecot] Problem with rc10, perhaps 11-15
by Steven F Siirila 03 Dec '06

03 Dec '06

I don't recall if I mentioned this on the list, but when you are configured with mbox format, and a user has no Dovecot index files yet, and the config is such that mbox_min_index_size is set to non-zero, non-default (128 in my test case), dovecot deliver fails. Commenting out "mbox_min_index_size" fixed the problem, and the indexes then get created. This problems exists in RC10 -- I'm mentioned this in case it still exists in the latest revs so it can get fixed before release. -- Steven F.

[Dovecot] IMAPS works, IMAP does not
by Peter Lindgren 03 Dec '06

03 Dec '06

Hello! I have a simple (I think) problem. I have had IMAPS working fine for a long time. Now I want to start to use IMAP and STARTLS, since my mobile SonyEricsson P900 can't use IMAPS directly. But I can't connect even locally to the IMAP port (143), no-one listens there according to netstat (*.imaps is in LISTEN state). I have the following settings in my /etc/dovecot.conf: protocols = imap imaps ssl_cert_file = /etc/ssl/dovecotcert.pem ssl_key_file = /etc/ssl/private/dovecot.pem disable_plaintext_auth = no login_user = _dovecot login_greeting = Dovecot@casiopea ready. mail_read_mmaped = yes mmap_no_write = no protocol imap { login_greeting_capability = yes } protocol pop3 { } auth_verbose = yes auth default { mechanisms = cram-md5 digest-md5 passdb passwd { } userdb passwd { } user = root } I have restarted (SIGTERM) dovecot to be sure that dovecot is restarted. I still run 1.0beta3 on OpenBSD. TIA, Peter -- Peter Lindgren, dataingenjör E-post: peter "at" norrskenkonsult punkt com http://www.norrskenkonsult.com

[Dovecot] shared folder
by T. Horsnell 03 Dec '06

03 Dec '06

The dovecot wiki says: The only way to implement shared folders with Dovecot 0.99.x is to create a "shared userid" which all of the users log in to read mail. Does this mean that folders owned by that shared uid can be *simultaneously* manipulated by multiple users logged in to that shared uid? This doesnt seem to be the case on my dovecot-0.99.11-4.EL4 system, and before investigating further I just wanted to check whether it should be possible or not. Cheers, Terry.

[Dovecot] Nested folders in FS supported yet?
by Sweth Chandramouli 03 Dec '06

03 Dec '06

The last time I checked, dovecot didn't support having nested IMAP folders be implemented via actual nested maildir folders in the filesystem, but that feature was on the "someday maybe it'll happen list", IIRC. I can't find any recent mention of that feature or its absence on the web or in the list archives; is it still on the someday list? (If it isn't implemented yet, does anyone know of an IMAP server that DOES support it?) Thanks, Sweth. -- Sweth Chandramouli sweth(a)ethicalhomes.com - http://EthicalHomes.com/ Thinking about buying a home, but feel like the local real estate market has left you behind?

[Dovecot] Heimdal & gssapi.h

I've had some trouble compiling GSSAPI on SuSE Enterprise 9 using Heimdal. It turns out that this installation has /usr/include/heimdal/gssapi.h rather than gssapi/gssapi.h. krb5-config correctly sets -I/usr/include/heimdal in the CFLAGS.

[Dovecot] Can't remove folder
by Leroy van Logchem 03 Dec '06

03 Dec '06

Hello, Here is a 'me too' somewhat like: http://www.dovecot.org/list/dovecot/2006-January/010759.html Example scenario: /u/username/Mail/subfolder/somebox subfolder is a directory somebox is a mbox When I use Thunderbird's "Delete folder" function on the somebox the message appears: "Target mailbox doesn't allow inferiour mailboxes". Thunderbird, by default, tries to move it to Trash instead of deleting it directly. When I change the preference to "Remove it immediately" it works. Which component is at fault here: - limitation of a mbox only setup? - thunderbird should know - limitation of the imap protocol to advice the client it's mbox backed - feature of dovecot, could it be fixed or worked around somehow -- Leroy

[Dovecot] Logging
by Steven F Siirila 03 Dec '06

03 Dec '06

In trying to determine why someone was unable to use port 110 w/STLS (POP) I had great difficulty finding the session in which the user switched to this port from using port 995. This is because Dovecot does not log any port number information. Furthermore, it isn't obvious to me if it logs whether a session was negotiated SSL (via STARTTLS w/IMAP or STLS w/POP) or started out SSL (ports 993 and 995). If this seems reasonable, I can whip up a patch to log this information. However, I'd rather see Dovecot 1.0 released first. -- Steven F.

[Dovecot] authentication
by eric 03 Dec '06

03 Dec '06

Good evening from Aotearoa; First some details: Clients are all Outlook2003 on XP yawn Server is Suse 9.3 Samba, postfix, fetchmail and dovecot 1.0 rc13 I succesfully installed Dovecot on my test network at home, but at the job site its a mystery. I seem to be able to get one client to authenticate but not another. And only if i created a password file consisting of logins and no passwords. Dovecot won't use standard unix passwd successfully. So here is the conf: base_dir = /var/run/dovecot/ protocols = pop3 listen = *:110 disable_plaintext_auth = no ssl_listen = ssl_disable = yes login_dir = /var/run/dovecot/login login_user = dovecot login_greeting = Dovecot ready. mail_extra_groups = users mail last_valid_uid = 2000 pop3_uidl_format = %08Xu%08Xv protocol lda { # Address to use when sending rejection mails. postmaster_address = postmaster(a)example.com } auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ auth_debug_passwords = yes auth default { mechanisms = plain passdb passwd-file { args = /usr/local/etc/passwords } userdb passwd { } user = root default_mail_env = mbox:/var/spool/mail/:INBOX=/var/spool/mail/%u And here is a sample of two of the syslogs.: I am not worried about the UID warning,I was try to login on from various clients.

[Dovecot] Problems using Squirrelmail / Dovecot / Sendmail / Fedora Core 6 - ERROR: Connection dropped by IMAP server
by Alexander Lapajne 03 Dec '06

03 Dec '06

Hello I just installed Fedora Core 6 and I'm having problems with SquirrelMail. I'm using Squirrelmail/Dovecot/Sendmail and when I log into Squirrelmail and try to view any folder that contains any messages I get: ERROR: Connection dropped by IMAP server. Query: SORT (ARRIVAL) ISO-8859-1 ALL Now, I've tried to disable server side sorting in Squirrelmail but that only leads to a new error message: ERROR: Connection dropped by IMAP server. Query: FETCH 1:* (FLAGS UID RFC822.SIZE INTERNALDATE BODY.PEEK[HEADER.FIELDS (Date To Cc From Subject X-Priority Importance Priority Content-Type)]) I'm using the default setup and POP3 mail is working. Using Thunderbird I can read email using POP3. So the problem only appears when using Squirrelmail. I had the exact same setup in Fedora Core 5 and it was working perfectly. Same config files and everything. _________________________________________________________ Flyger tiden iväg? Fånga dagen med Yahoo! Mails inbyggda kalender.

[Dovecot] %s service variable substitution
by Jim Horner 02 Dec '06

02 Dec '06

I'm using 1.0rc15. We switched over to using deliver LDA and using dovecot's sasl implementation for postfix... In our ldap configuration we were using (similar for password filter) user_filter = (&(objectClass=mailUser)(mail=%u)(mailSettingValue=%s)) The problem is these new services, namely deliver and postfix, are accessing the authentication mechanisms and I am not sure what to put in ldap so the %s can match. Each user currently only has a mailSettingValue=IMAP. This can be expanded for multiple entries. Thanks, Jim

[Dovecot] Quota's with Thunderbird
by Richard Mayhew - Nashua Mobile Broadband Division 30 Nov '06

30 Nov '06

Hi, Does anyone know how to get Thunderbird to correctly report the mailbox quota's? I know Dovecot is correctly enforcing the quotas on the mailbox when using Thunderbird, but Thunderbird reports that the "server does not support quota's" when trying to view the usage? Is Thunderbird expecting something different? Viewing the mailbox through Squirelmail, the quota's are reported correctly, so I would thnk that Thunderbird is where the problem lies. Regards Richard

[Dovecot] lmtp: help needed
by Leonardo Lanzi 30 Nov '06

30 Nov '06

Hi all, parsing the mailing list archive, it seems that the lmtp-server will not be developed soon, so I'm looking for someone that could help me in writing one, even if not the best one. That's why: I've just started to study dovecot, as I was recruited, just about forced, to help The System Manager of our University in the global e-mail migration - more than 37'000 users, 440 mailing lists, everything synchronized with administrative databases and so on - from open-vms (yes... you have not sight problems: OpenVMS ... please don't blame us). In particular, we have (we'd like so much) to directly deliver from a front-end load-balanced anti-spam&virus all "good" messages into maildirs, updating at the same time the indexes for dovecot. Our idea is to write an lmtp, possibly not from scratch; we have already a threaded server, recently born as a raw smtp server to test the antivirus and antispam system under heavy load (before to start the migration), that can be converted to lmtp protocol, but we lack of information on the dovecot API for delivering in a "dovecot-way". As often occurs, we have not months to get it done, therefore _any_ kind of suggestion will be very much appreciated. Thank you all for the help, and patience! -- Leonardo Lanzi Department of Physics - University of Florence - Italy -- PS - Examples of help: 1. "The code is self-explaining, but obviously you're too old to learn: accept to be in the mist, and switch to cyrus" 2. "the following n-functions ... of deliver can accept your data from memory and do all the job" 3. "I've already done everything, download it at the following url..." 3a. "I've already done everything, but you must send me, _before_, your smtp stressing server, or all your tests on latency of irq handlers with 2.6 kernel, or at least one 18-year-old scottish-malt-whisky bottle!"

[Dovecot] Subfolders with Thunderbird and maildir?
by Andrew Z 30 Nov '06

30 Nov '06

I setup a test dovecot-1.0-0.beta8.2.fc5 and left most of the settings as the defaults. In Thunderbird 1.5.0.8 Windows, when I tried to create a subfolder named "subfolder" under INBOX, it showed up as the same level a INBOX and with the name "INBOX^subfolder". I was able to manually create a subfolder using "mkdir ~/mail/test_manual_subfolder; touch ~/mail_test_subfolder/blah" and then subscribing to it. That's too much work. :) Now when I try to create a subfolder of a non-inbox folder, nothing happens (not even an error). Screen shot: http://img452.imageshack.us/my.php?image=subfoldersthunderbird15ao6.png The Dovecot system is Fedora Core 5 x86 and an NFS client for /home. I'm considering switching from Trustix, UW-IMAP, and mbox. I'm also considering changing INBOX to a Maildir (not /var/spool/mail/%u). Andrew

[Dovecot] MAILDIR environment
by adcx＠server101.com 29 Nov '06

29 Nov '06

from docs/mail-storages.txt: "Also as a special case, if MAILDIR environment exists, maildir storage is used with the directory specified in it." Forgive me if this seems obvious, but is this talking about setting MAILDIR as an enivornment variable? I have it set on my system in both /etc/profile and ~/.bash_profile: MAILDIR=/path/to/maildir/ export MAILDIR and have confirmed this worked by running 'echo $MAILDIR'. I've logged the user in question out and then in again, as well as restarting dovecot but it still defaults to checking ~/Maildir when the user logs in. Setting the location using default_mail_env is not an option here as I need the fallback behaviour that occurs when default_mail_env is not set. Any advice appreciated.

[Dovecot] Redundant shared mail store?
by Jasper Bryant-Greene 29 Nov '06

29 Nov '06

Hi guys I'm about to embark on a project replacing a legacy single mail server running proprietary software with a cluster of Dovecot servers. We clearly need a shared mail store for these servers, but we are not happy with simply using a server running NFS as this becomes a single point of failure. What have other people used? AFAICT our options are: * A shared block device (Fibre Channel, iSCSI, ATAoE etc) running GFS or similar to allow multiple servers to access it concurrently * Two or more NFS units, either with built-in support for replication of FS changes and failover, or with scripts for achieving this functionality I prefer option 1, although it's expensive. What have other people used? Do we have other options? TIA -- Jasper Bryant-Greene Director Album Limited jasper(a)albumltd.co.nz +64 21 708 334 / 0800 425 286 http://www.albumltd.co.nz/

[Dovecot] Quota problems on uidlist files
by James Nunnerley 29 Nov '06

29 Nov '06

Hi All, Please excuse me for this somewhat a slightly uneducated explanation of a problem we are experiencing. I'm more a web developer rather than a sysadmin, and have only recently been looking at how exactly dovecot works. We're having a problem when users/groups quotas are reached on our server platform. Our platform bases quotas on groups - i.e. domains, so a single user has a user username and group of their domain; and the domain has a set amount of space available. This means that if they then try and access their email, via either imap or in most cases webmail, it would seem that dovecot is unable to create the dovecot-uidlist file - which makes complete sense, because it's running as that user and under the group as detailed above.. We've tried changing a pre-existing file to have group ownership of nobody, but from what we can gather, this file is not actually updated, but deleted and recreated when changes occur. One solution would be to take the dovecot-uidlist file out of the mail directory structure, on which the quotas are enforced, but this is not configurable in dovecot. Alternatively, having someway of changing to ownership of the file would also get around this problem. Does anyone have any experience of either a work around for this, or something which we can change in dovecot that will allow users to create a dovecot file, even if they are over quotas? Many thanks James James Nunnerley Applications Developer Namesco Limited

[Dovecot] Authentication
by eric 29 Nov '06

29 Nov '06

Try as I may, I cannot get Dovecot to allow anything but blank passwords listed in a custom file I made for the purpose. It will not recognise anybody in passwd. Only using POP3 on an internal network so little danger of incursions. Once I created a password file with user names and no password, one user could login (from Outlook 2003) but another could not. Telnet test also fails to authenticate. I have allowed the group to write to the /var/spool/folder Syslog simply showed authentication failed. Relevant bits of my config: disable plain text = no mail extra group = users pop3 uidl format %08Xu%08Xv pasted direct from the help I have un commented auth user name characteres mechanisms = plain and I have set auth debug passwords = yes user = root System: Suse 9.3 Dovecot 1.0 rc13 Any ideas? -- John McC

Our users tend to use one of the following: Apple Mail Entourage (basically Outlook for Mac) Outlook Outlook Express Thunderbird and then there's the webmail system we provide. Apple Mail has virtually no limit on messages it will handle. I currently have over 500,000 emails in my Apple Mail. It stores email much like Dovecot; each email is in a separate file. This makes backups a breeze, which a reason to switch to a server that uses maildir. Entourage, Outlook Express and Outlook have problems if the data file exceeds 2GB. This is an ongoing problem and I'm hoping by keeping email on the server, the support headaches will be reduced. I'm not sure what limits Thunderbird has. I use Thunderbird to connect to the main directory for all email and it doesn't seem to have any trouble handling it. Currently, everyone is using POP3 but I want to move to IMAP. (Thunderbird is the only client that connects via IMAP on our systems) The motivation for moving to IMAP is primarily for spam handling. Instead of users contacting us for emails that might be caught as spam, the spam will be moved to a "junk mail" folder. Then the user can peruse the folder themselves to find any legit email improperly categorized as junk. Vacation messages is the other item that is prompting a change. Everyone is screaming for that feature.

What this means though, is that ever users has 3-4 set folders, that are forced on. I now have a few users that want to use POP3.

[Dovecot] mailadm? authentication vs. authorization?
by David Lee 24 Nov '06

24 Nov '06

Does "dovecot" have anything similar to the UW IMAP "mailadm" group operation? From near the end of: http://www.washington.edu/imap/documentation/RELNOTES.html 'Support for SASL authentication identity vs. authorization identity in the IMAP and POP3 servers. If the user indicated by the authentication identity is in the "mailadm" group, he may specify any authorization identity and get logged in as the authorization identity user.' This allows an email administrator (member of group "mailadm") to sort out problems in a user's mailbox as that user identifier. (We try to train our users not to reveal their password to anyone, not even to our own staff. But sometimes, as staff, it is very useful to be able to do operations as a particular user to diagnose a problem.) -- : David Lee I.T.

[Dovecot] Two email accounts writing to one nfs shared home directory
by John McDonald 23 Nov '06

23 Nov '06

I use dovecot as a local imap server on my desktop machine due to the fact that my workplace only support POP3. I use fetchmail to pop, postfix to deliver, and dovecot for client access. At present I have a single email account which is the same as my system login and have postfix and dovecot setup to use ~/Maildir. The home directories on our system are served from a central file system, using nfs, which has full backup/disaster recovery policy implemented. I now need to setup a second separate email account for a specific task. Our sysadmins have setup this account for me on the POP3 server. The problem is that this account does not have a home directory on our system and therefore I can't write to ~/Maildir. What I would like to do is setup the same type of system for this second account without necessitating the creation of a home directory. That is, I would like a second Maildir folder in my own user account to which this second email account's messages are delivered. This way I will have full backup of the messages. What is the most straightforward way of achieving this? (or can it be done at all?) Thanks for the help. Regards, John McDonald.

[Dovecot] Which version of dovecat I must use quit mysql 14.12 5.0.24a?
by maria.freixes_graells＠alcatel.es 22 Nov '06

22 Nov '06

Hello everybody!! I'm new on linux machine configuration, and I have a question related to product versions. We've Linux seweb1 2.6.9-5.EL installed, but instead of install the mysql product from "Red Hat Interprise Linux 4" CD what is mysql-0:4.1.7-4.RHEL4.1.i386, we installed: *mysql 14.12 5.0.24a *So, now, when we tried to install dovecot, it needs mysql-0:4.1.7-4.RHEL4.1.i386, perl-DBD-MySQL-0:2.9004-3.1.i386 and postgresql-libs-0:74.6-1.RHEL4.2.i386. I don't want to install these packets from mysql because I'm afraid to crash the mysql that we've now working...... So, my question is, what I need to do in this case? Can I install the mysql CD version without interferring to our actual BD working: *mysql 14.12 5.0.24a? *Or....Which version of dovecot we must install in order to work with *mysql 14.12 5.0.24a. *I would be very gratefully if you could help me, beacause we afraid to crash the BD that is working now, and we don't know how to install dovecot in this case. Best regards, Maria

[Dovecot] assertion failed: (need_space == (uoff_t)-mails[idx].space)
by David King 21 Nov '06

21 Nov '06

I'm running Dovecot dovecot-1.0.r13 on FreeBSD (FreeBSD 6.1-RELEASE- p10). Mail is stored in mbox format (dovecot.conf after the msg). Procmail delivers mail to subfolders under ~/.mail, locking using dotfiles. One folder in particular for one user has an mbox file ~/.mail/Cron. Quite often, I'll see that procmail processes are stacking up because ~/.mail/Cron.lock exists, and they (rightly) refuse to deliver to a locked mailbox. It seems that dovecot is creating these lock files and then dying. The .lock file's contents refer to a PID that, by the time I see the lockfile, doesn't exist. It appears that dovecot is leaving behind the lock files, after exiting with a signal 6 (sometimes 11) and leaving behind messages in /var/log/maillog (and the end of this message). In dovecot.conf I have mail_drop_priv_before_exec = no, but I can't find the core file that I would expect it to dump, so I can't give you a backtrace. Hopefully the assertion in /var/log/maillog is enough. With ~/.mail/Cron perpetually locked, I'm not able to receive mail in this folder, and with any IMAP client that tries to access that folder having the IMAP server shut down, it keeps me from getting mail. Any ideas? # tail /var/log/maillog Nov 11 23:05:32 melchoir dovecot: imap-login: Login: user=<ketralnis>, method=PLAIN, rip=10.0.1.239, lip=10.0.0.1, TLS Nov 11 23:05:32 melchoir dovecot: IMAP(ketralnis): Disconnected: Logged out Nov 11 23:06:52 melchoir dovecot: IMAP(ketralnis): file mbox-sync- rewrite.c: line 405 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) Nov 11 23:06:52 melchoir dovecot: child 16929 (imap) killed with signal 6 Here is dovecot.conf: # cat /usr/local/etc/dovecot.conf | sed -E 's/^(.*)#.*$/\1/' | grep - Ev '(^#|^[ ]*$' protocols = imap pop3 imaps pop3s ssl_cert_file = /etc/ssl/mail-cert.pem ssl_key_file = /etc/ssl/private/mail-key.pem disable_plaintext_auth = no login_user = dovecot verbose_proctitle = yes first_valid_gid = 0 mail_extra_groups = mail default_mail_env = mbox:%h/.mail:INBOX=/var/mail/%u mmap_disable = no lock_method = fcntl mbox_read_locks = dotlock mbox_write_locks = dotlock fcntl mail_drop_priv_before_exec = no protocol imap { login_greeting_capability = yes imap_client_workarounds = delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep } protocol pop3 { pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth default { mechanisms = plain login passdb pam { } userdb passwd { } userdb prefetch { } user = root }

[Dovecot] Dovecot on Solaris

For those running Dovecot on Solaris, what are your positive/negative experiences with building the software with CC vs. GCC? We are currently letting ./configure find our gcc and build with it, but wondered if anyone has any experience with Sun CC (does it even compile, for example). -- Steven F.

[Dovecot] RAID benchmarks
by Ethan Sommer 21 Nov '06

21 Nov '06

We (a small college with about 3000 active accounts) are currently in the process of moving from UW IMAP running on linux to dovecot running on a cluster of 3 or 4 new faster Linux machines. (Initially using perdition to split the load.) As we are building and designing the system, I'm attempting to take (or find) benchmarks everywhere I can in order to make informed decisions and so that when we need something faster we have something to compare it to. I've looked all over the Internet and I haven't seen very many good benchmarks running on recent hardware for things like this. Even simple things like how different raid levels perform with fast CPUs and really fast disks. We recently got the first of the cluster machines (which has the following specs: (from penguin computing) 2x 1.6ghz woodcrest (so 4 cores total) 2g ram (we may upgrade to more, depending on what we seem to need) 6x 15k SAS 73G hard drives. I've always read that RAID 10 is the RAID of choice for mail, because the checksums take time and whatnot, but on a system that fast I'm sure that's not an issue (which I could see from the cpu usage during benchmarks.) We were also wondering whether RAID6 would be a good option since it would give more redundancy. (raid6 allows 2 drive failures) All tests were run on ext3 with all 6 disks in the raid. Everything is using Linux software raid. I used bonnie++ to run the benchmarks, and here are the initial results we got: Output Input RAID "Per Chr" "Block" "Per Chr" "Block" RAID6 34628, 97983, 23316, 39077 RAID5 39559, 32715, 32036, 52231 RAID10 38816, 229062, 40645, 267418 I assume that mail running maildir (as we intend to do) is somewhere between writing one char at a time and writing huge blocks to fill 4g files. Since the Per Chr values seemed to have maxed out the CPU and we'll have 4 cores available, I tried the same thing running 4 copies of bonnie at once and adding the results. (I worked backwards and didn't bother with raid 6 for obvious reasons) Output Input RAID "Per Chr" "Block" "Per Chr" "Block" RAID5 37465, 37095, 102828, 174263 RAID10 111239, 128287, 93400, 230320 So, if our system is ever running full out, basically disk bound, it should be able to handle about 4X as many writes and at least as many reads using RAID10 than raid 5, and since raid 6 was pretty similar to raid 5 in the first tests, I assume it will be here too. I have the full bonnie results if anyone's interested. I also plan to come up with some basic benchmarks as we start to actually have dovecot working as we want it to. (Possibly using the macs in our labs and XGrid as a "client".. finally a use for that thing :) ) Do people have suggestions as to what to test for a primarily IMAP (+ a little POP) server? I was thinking of doing something similar to http://www.courier-mta.org/mbox-vs-maildir/ which selects a mail box, deletes and expunges a message, fetches a few messages, and then does some searches. Also, while I have the opportunity, are there any other benchmarks I should run? I suppose I could compare dovecot with mbox vs maildir, with indexing and without. Dovecot with indexing but the indexes deleted, etc. I could compare dovecot to uw imap. Anything else? I probably can't justify the time to get cyrus up and running. (I did that a few months ago when deciding which server to use...) Ethan Sommer -- -- Ethan Sommer Systems Administrator Gustavus Adolphus College 507-933-7042 sommere(a)gac.edu

[Dovecot] rc14 and rc15 performance issues
by Jeff A. Earickson 21 Nov '06

21 Nov '06

Hi, I am stuck at rc13 because rc14 and rc15 have both failed to keep up with imap connections on my (slow old) system. I have the problem where if a lot of people check their email at once (like at the top of the hour) then my load goes way up and things slow to a crawl. My setup: Solaris 10 on an E220R, mbox format, imap and imaps only. I also use "login_process_per_connection = no". Any suggestions? Jeff Earickson Colby College

I once used StudioCC to compile dovecot to see if the problem I had was a compiler bug, but in general, I use gcc since a lot of software is tested against it.

[Dovecot] BUG: passdb checkpassword {} and lastauth file
by Max A 20 Nov '06

20 Nov '06

(Repeat, because on the first message there was no reaction) Hi. If checkpassword interface is used for working with vpopmail, function vpopmail "Record time and ip of last auth attempt" (--enable-auth-logging option for configure) won't work - the file "lastauth" is created in Maildir, but does not contain ip-address. If I had correctly understood, dovecot woldn't have set a enviroment variable TCPREMOTEIP for vchkpw. If changes are made in auth/passdb-checkpassword.c (a patch in attachment), everything will work. Probably, the patch is incorrect and does not solve all problems, however the request is to pay attention to existence of the problem. Also it is possible, that a similar problem exists with other variables TCP UCSPI protocol (http://cr.yp.to/proto/ucspi-tcp.txt) P.S. If use the interface vpopmail instead of checkpassword, the file "lastauth" will not be created at all, that is a little bit inconvenient. ********************************** System: dovecot-1.0.rc10 vpopmail-5.4.17 ASP Linux Server II (RHEL3 clone) kernel 2.4.21-47.EL.aspsmp CPU architecture: x86 (IBM xSeries 336) Filesystem: ext3 ********************************** dovecot configuration: base_dir = /var/run/dovecot/ protocols = imap pop3 disable_plaintext_auth = no ssl_disable = yes login_greeting = Ready. first_valid_uid = 89 last_valid_uid = 89 first_valid_gid = 89 last_valid_gid = 89 protocol imap { listen = 81.26.136.8:144 mail_executable = /usr/local/libexec/dovecot/imap mail_plugins = quota imap_quota mail_plugin_dir = /usr/local/lib/dovecot/imap imap_client_workarounds = delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep } protocol pop3 { listen = 81.26.136.8:112 login_executable = /usr/local/libexec/dovecot/pop3-login mail_executable = /usr/local/libexec/dovecot/pop3 pop3_uidl_format = %f mail_plugins = quota mail_plugin_dir = /usr/local/lib/dovecot/pop3 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth default { mechanisms = plain login passdb checkpassword { args = /var/qmail/vpopmail/bin/vchkpw } userdb prefetch { } user = root } dict { } plugin { quota = maildir } *************************************** dovecot configure options: ./configure \ --disable-ipv6 \ --prefix=/usr/local \ --sysconfdir=/etc/dovecot \ --without-passwd \ --without-passwd-file \ --without-shadow \ --without-pam \ --without-bsdauth \ --with-checkpassword \ --with-vpopmail \ --without-static-userdb \ --with-prefetch-userdb \ --without-sql \ --without-pgsql \ --without-mysql \ --without-sqlite \ --with-ssl=openssl \ --with-pop3d \ --without-deliver \ --with-storages=maildir \ --with-docs ***************************************** vpopmail configure options: ./configure \ --enable-auth-module=cdb \ --enable-logging=p \ --enable-md5-passwords \ --enable-make-seekable \ --enable-file-sync \ --enable-ip-alias-domains \ --enable-clear-passwd \ --disable-roaming-users \ --disable-learn-passwords \ --disable-passwd \ --enable-auth-logging diff -ur dovecot-1.0.rc10.orig/src/auth/passdb-checkpassword.c dovecot-1.0.rc10/src/auth/passdb-checkpassword.c --- dovecot-1.0.rc10.orig/src/auth/passdb-checkpassword.c 2006-08-22 06:37:56.000000000 +0400 +++ dovecot-1.0.rc10/src/auth/passdb-checkpassword.c 2006-10-17 16:47:09.000000000 +0400 @@ -226,6 +226,10 @@ env_put(t_strconcat("REMOTE_IP=", net_ip2addr(&request->remote_ip), NULL)); + env_put(t_strconcat("TCPREMOTEIP=", + net_ip2addr(&request->remote_ip), + NULL)); + } if (request->master_user != NULL) { env_put(t_strconcat("MASTER_USER=",

[Dovecot] dovecot and ldap passwords.
by Mauro Sanna 20 Nov '06

20 Nov '06

Hallo. First of all I'm sorry for my bad english. I have a question about how dovecot use passwords. I have all my mail accounts in a ldap database. The user password are stored in form: {crypt}mypasswd. In dovecot-ldap.conf I have default_pass_scheme = CRYPT. All is working fine. The problem in the crypt scheme is that I can't have passwords more than 8 characters long. So I've tried to change the type of the ldap passwords in SSHA or SMD5, but in this way the users can't authenticate yourselfs. Dovecot doesn't understand SSHA or SMD5?

[Dovecot] Problem with rc10
by Steven F Siirila 20 Nov '06

20 Nov '06

I just upgraded our test server from rc6 to rc10... ISSUE #1 I noticed that we no longer are getting two "From_" lines. However, the one that was good (had the original sender e-mail address) is now gone. The one with "dovecot.deliver" remains. I attempted to add "-d test" to the mailbox_command line in main.cf as follows: mailbox_command = /opt/dovecot/libexec/dovecot/deliver -d test and things turned ugly and caused Postfix to defer messages: Oct 17 16:31:50 hostname postfix/local[7230]: D14632C9C: to=<someuser@somehost>, relay=local, delay=3.6, delays=3/0.02/0/0.62, dsn=4.3.0, status=deferred (temporary failure) I removed the "-d test" from the Postfix main.cf and the problem went away. So, how do I fix the "From_" lines? ISSUE #2 After upgrading, messages cannot be moved from the INBOX to a folder. Thunderbird claims there was an internal error and to consule the server logs, but I see nothing in the dovecot logs that would indicate what's going on. For example, I attempted to move a message into my Trash folder which did not currently have any index files. Here is a Solaris truss output of that attempt: poll(0x000B4C98, 2, 999) = 0 poll(0x000B4C98, 2, 0) = 0 poll(0x000B4C98, 2, 999) = 1 read(0, " D O N E\r\n", 3323) = 6 write(1, " 2 8 O K I d l e c".., 23) = 23 read(0, 0x000BC5BB, 3317) Err#11 EAGAIN poll(0x000B4C98, 2, 675) = 1 read(0, " 3 0 u i d c o p y ".., 3317) = 27 stat64("/home/sfs/Trash", 0xFFBFF5C8) = 0 alarm(120) = 0 fcntl(6, F_SETLKW64, 0xFFBFF308) = 0 alarm(0) = 120 stat64("/home/sfs/Trash", 0xFFBFF640) = 0 mkdir("/home/sfs/.imap/Trash", 0770) Err#17 EEXIST stat64("/home/sfs/.imap/Trash", 0xFFBFF4C0) = 0 stat64("/home/sfs/Trash", 0xFFBFF4C0) = 0 time() = 1161122396 open64("/home/sfs/.imap/Trash/dovecot.index", O_RDWR) Err#2 ENOENT open64("/home/sfs/.imap/Trash/dovecot.index", O_RDWR) Err#2 ENOENT write(1, " 3 0 N O I n t e r n".., 96) = 96 poll(0x000B4C98, 2, 588) = 0 poll(0x000B4C98, 2, 0) = 0 poll(0x000B4C98, 2, 410) = 0 Someone else using a different IMAP client caused these errors to occur (this is even after I wiped all of their dovecot index files): Oct 17 16:43:11 earth.tc.umn.edu dovecot: IMAP(kor): Corrupted transaction log file /home/kor/.imap/INBOX/dovecot.index.log: invalid indexid (1161121145 != 1156185395) Oct 17 16:43:11 earth.tc.umn.edu dovecot: IMAP(kor): Corrupted transaction log file /home/kor/.imap/INBOX/dovecot.index.log: invalid new transaction log sequence (6 >= 6) Oct 17 16:47:09 earth.tc.umn.edu dovecot: IMAP(kor): Corrupted transaction log file /home/kor/.imap/INBOX/dovecot.index.log: invalid indexid (1161121145 != 1161120959) Oct 17 16:47:09 earth.tc.umn.edu dovecot: IMAP(kor): Corrupted transaction log file /home/kor/.imap/INBOX/dovecot.index.log: invalid new transaction log sequence (2 >= 2) Oct 17 17:05:59 earth.tc.umn.edu dovecot: IMAP(kor): Corrupted transaction log file /home/kor/.imap/INBOX/dovecot.index.log: invalid indexid (1161121145 != 1161120959) Oct 17 17:05:59 earth.tc.umn.edu dovecot: IMAP(kor): Corrupted transaction log file /home/kor/.imap/INBOX/dovecot.index.log: invalid new transaction log sequence (4 >= 4) Here are our non-standard dovecot.conf items: protocols = imap imaps pop3 pop3s shutdown_clients = no syslog_facility = local6 ssl_cert_file = /etc/opt/openssl/certs/dovecot.pem ssl_key_file = /etc/opt/openssl/private/dovecot.pem default_mail_env = mbox:~/:INBOX=/var/mail/%u # Default namespace namespace private { separator = / prefix = location = mbox:~/:INBOX=/var/mail/%u inbox = yes hidden = yes } mail_full_filesystem_access = yes first_valid_uid = 100 max_mail_processes = 8192 mbox_min_index_size = 128 imap_client_workarounds = delay-newmail outlook-idle tb-extra-mailbox-sep pop3_uidl_format = %08Xu%08Xv protocol lda { postmaster_address = postmaster(a)umn.edu mail_plugins = cmusieve } auth_verbose = yes auth_debug = yes auth default { passdb pam { args = session=yes * } } I am now backing out to rc6 for now... we never saw this behavior on rc6. -- Steven F.

[Dovecot] Problems Creating Core Dumps
by Joseph D. Wagner 20 Nov '06

20 Nov '06

Dovecot 1.0.rc15 crashed on my FC4 server, but it didn't create a core dump. Upon further research, I found these lines tucked away in the /etc/rc.d/init.d/functions file: # make sure it doesn't core dump anywhere unless requested ulimit -S -c ${DAEMON_COREFILE_LIMIT:-0} >/dev/null 2>&1 The /etc/rc.d/init.d/functions file is a master file that is referenced by all of the init scripts, so I didn't want to change it. Instead, I created a file /etc/sysconfig/dovecot with the following line: DAEMON_COREFILE_LIMIT=unlimited If I'm reading the /etc/rc.d/init.d/functions file correctly, this should work, but my bash is rusty. I was hoping someone else could check my work. Joseph D. Wagner

[Dovecot] Backtraces without core dumps
by Timo Sirainen 19 Nov '06

19 Nov '06

Since getting core dumps seems to be difficult sometimes, especially with login processes, I've now added code to log the backtrace when Dovecot crashes in some assert check (or some other reason why it decides to abort()). This code works with Linux and Solaris, but I don't know about BSDs. Apparently there exists libexecinfo library which could be used. I think this code could be used to log backtraces also for segfaults, but that's more risky so I didn't do it yet. Maybe it should be done only optionally. If you're interested in trying, the code is now in CVS and in the latest nightly snapshot. When it crashes, it prints something like: Panic: file client.c: line 55 (client_create): assertion failed: (my_client != NULL) Error: Backtrace: ./imap [0x80b2ffa] -> ./imap [0x80b2ecc] -> ./imap [0x805bbb3] -> ./imap(main+0x426) [0x80634a6] -> /lib/tls/libc.so.6 (__libc_start_main+0xc8) [0xb7e53ea8] -> ./imap [0x80566a1] Looks like the symbol name resolving doesn't work all that great. But here gdb will help you: gdb ./imap (gdb) b *0x80b2ffa Breakpoint 1 at 0x80b2ffa: file failures.c, line 126. (gdb) b *0x80b2ecc Breakpoint 2 at 0x80b2ecc: file failures.c, line 185. (gdb) b *0x805bbb3 Breakpoint 3 at 0x805bbb3 (gdb) b *0x80634a6 Breakpoint 4 at 0x80634a6: file main.c, line 223. That went pretty well, except for some reason it couldn't figure out where 0x805bbb3 was. To get some kind of an idea about that, you can do: (gdb) x 0x805bbb3 0x805bbb3 <client_create+467>: 0x90909090 If someone knows better ways to do all of this, please tell me too :)

[Dovecot] Dovecot (unofficial) patches
by Egbert Jan 19 Nov '06

19 Nov '06

Dear list, As a recent dovecot addict, I'm a bit puzzled by the sheer amount of patches available. I have not seen the history of these patches and I could not find a README explainng the patches. Are all these personal wishes/nice to have things or are they (to be) incorporated in dovecot-final? I use rpmbuild to create new rpms from the latest tarball but in that process still several patches are included during the build. I wonder if they are still needed in rc15. I use the orignal spec file (the latest I could find) was created for rc7 and in there I see: Patch2 dovecot-0.99.10-mbox-patch Seems to be to change the order of ./Mail before ./mail Patch3 dovecot-CVE-2006-2414 Overview from CVE db:Directory traversal vulnerability in Dovecot 1.0 beta and 1.0 allows remote attackers to list files and directories under the mbox parent directory and obtain mailbox names via ".." sequences in the (1) LIST or (2) DELETE IMAP command. I'm not a spec file wizard, so I change as less as possible. Unfortunately the maintainer (Jerome Soyer) has never responded to my emails. My server runs Mandriva Official 2007.0 and Postfix 2.3.3 and dovecot rc14 (will move to rc15 soon). TNX EgbertJan (NL)

[Dovecot] TLS timeout with Thunderbird
by Jason Dixon 19 Nov '06

19 Nov '06

I'm trying to get dovecot working with various clients on my new mailserver. I installed the base rc2 that comes with OpenBSD 4.0, then upgraded to rc14 when I ran into problems with TLS and Thunderbird. The server has no problems with Mail.app on my laptop, but any connection attempts from Thunderbird timeout after the TCP handshake. 13:53:41.074438 66.x.x.2.50483 > 38.x.x.248.993: S 3787736038:3787736038(0) win 65535 <mss 1460,nop,wscale 0,nop,nop,timestamp 2064284084 0,sackOK,eol> (DF) 13:53:41.074554 38.x.x.248.993 > 66.x.x.2.50483: S 1565942120:1565942120(0) ack 3787736039 win 16384 <mss 1460,nop,nop,sackOK,nop,wscale 0,nop,nop,timestamp 2681405076 2064284084> (DF) 13:53:41.459434 66.x.x.2.50483 > 38.x.x.248.993: . ack 1 win 65535 <nop,nop,timestamp 2064284084 2681405076> (DF) 13:53:47.028621 66.x.x.2.50483 > 38.x.x.248.993: F 1:1(0) ack 1 win 65535 <nop,nop,timestamp 2064284096 2681405076> (DF) The only thing logged by dovecot is a disconnection event.

[Dovecot] Security hole #2: Off-by-one buffer overflow with mmap_disable=yes
by Timo Sirainen 19 Nov '06

19 Nov '06

Version: 1.0test53 .. 1.0.rc14 (ie. all 1.0alpha, 1.0beta and 1.0rc versions so far). 0.99.x versions are safe (they don't even have mmap_disable setting). Problem: When mmap_disable=yes setting is used, dovecot.index.cache file is read to memory using "file cache" code. It contains a "mapped pages" bitmask buffer. In some conditions when updating the buffer it allocates one byte too little. Exploitability: I think it's going to be pretty difficult to cause anything else than a crash, but I wouldn't say impossible. Only logged in IMAP/POP3 users can exploit this. In theory you might be able to exploit this for other users as well by sending them a lot of specially crafted emails, but this requires knowing what dovecot.index.cache file contains. Normally its contents can't be predicted, although perhaps with POP3 users it gets empty often enough that the exploit could be tried. Then again, the exploit requires having at least 4MB cache file, which won't happen with POP3 users before the mailbox has about 170k mails (if I counted right). With IMAP the cache file is used more, so it's easier to fill the 4MB with for example a lot of To-headers. Workaround: Use INDEX=MEMORY so the cache files aren't used at all. Fix: 1.0.rc15 fixes this. You can also use this patch: http://dovecot.org/patches/1.0/file-cache-buffer-overflow-fix.diff

[Dovecot] I/O leak
by Jim Horner 19 Nov '06

19 Nov '06

I upgraded from rc12 to rc14 last night... sifting through the logs I noticed the following. I point this out since it appears dovecot is in high gear bug-fix mode. This issue is not big for me; I rarely stop dovecot. My init.d script for dovecot is basically stop) killall dovecot imap-login I am guessing there might be a more graceful way to stop dovecot? Or rc14 fixed this? I see in rc14 changelog: - rc13 crashed if client disconnected while IDLEing but only user1 was IDLE.

http://dovecot.org/releases/dovecot-1.0.rc14.tar.gz http://dovecot.org/releases/dovecot-1.0.rc14.tar.gz.sig More fixes. "Duplicate header extension keywords" is the only known problem (or if I forgot something, remind me). I'll try to figure out a way to reproduce it easily and then get it fixed. * LDAP: Don't try to use ldap_bind() with empty passwords, since Windows 2003 AD skips password checking with them and just returns success. * verbose_ssl=yes: Don't bother logging "syscall failed: EOF" messages. No-one cares about them. + Dovecot sources should now compile without any warnings with gcc 3.2+ - rc13 crashed if client disconnected while IDLEing - LDAP: auth_bind=yes fixes - %variables: Fixed zero padding handling and documented it. %0.1n shouldn't enable it, and it really shouldn't stay for the next %variable. -sign also shouldn't stay for the next variable. - Don't leak opened .log.2 transaction logs. - Fixed a potential hang in IDLE command (probably really rare). - Fixed potential problems with client disconnecting while master was handling the login. - quota plugin didn't work in Mac OS X

[Dovecot] quota plugin enhancement request
by Michael Tibben 19 Nov '06

19 Nov '06

Hi am having a small issue with the quota plugin In Squirrelmail when a message is deleted, it seems to be copied to the Trash folder *before* it is deleted from the current folder. However if it is a large message being deleted and the mailbox is close to its quota limit, it means dovecot will deny the copy operation as the quota will be exceeded if the message is copied Because of this, I am wondering if it is possible to have an option for the quota plugin to track, but not enforce the quota. This is because I don't require quota enforcement on IMAP, as Postfix will enforce quota on incoming mail anyway. I hope this makes sense... Michael

[Dovecot] Is "Resource temporarily unavailable" an old problem?
by Ricardo Dias Campos 19 Nov '06

19 Nov '06

Hi. I've installed dovecot recently in a Fedora 5 Linux. It seemed to be OK but I begun to get the message "Can't connect to auth server at default: Resource temporarily unavailable". When I get the message, dovecot hangs. The problem is that "temporarily" is not quite true since the only way to get dovecot running again is to restart it. As a matter of fact, I cannot say that it never recovers. What I know is that it is out for a long, long time. Then a new problem arose: the time between hang-ups begun to diminish. Trying to find why I discovered that the number or dovecot-auth processes was too high (last time I got 169 processes, a lot of them <defuncts>). It seems that, if I kill all these processes, it takes more time before it hangs again. I looked up for messages in the Internet and I found a mail exchange between people from this list. The first hint I got was to upgrade dovecot. As I said, I'm using Fedora 5 and the version distributed with it was dovecot-1.0-0.beta2.7.i386. I upgraded it to dovecot-1.0-0.beta8.2.fc5.i386. I couldn't make any direct relantionship between this versions and the ones in dovecot site so I cannot tell what dovecot version I'm using in terms of dovecot site versioning. Any help is welcome. Thanks, Ricardo

[Dovecot] CHANGE REQUEST: Move config files out of main $sysconfdir
by Brian G. Peterson 19 Nov '06

19 Nov '06

Currently, dovecot places it's config files in $sysconfdir In Makefile.am, this is defines as: confdir = $(sysconfdir) It would be far more friendly to an already overloaded /etc/ directory, and easier to locate the files, to follow the now-common convention and place files in $sysconfdir / dovecot / ... on most systems this would mean: /etc/dovecot/ If there is only a dovecot.conf, it doesn't really matter, but when additional config files get added for ldap, sql, sieve, it starts to add up. Some distributions already make this change, but placing this change in the dovecot core would make it unnecessary for downstream packagers to make a change to the core dovecot distribution files.

(that's what you get from trying to debug something when you're too tired to think straight). I've now enabled debugging again, and have tried logging in from Outlook with ntlm-authentication. The log-entries are as follows: Nov 16 23:29:09 SD-Server dovecot: auth(default): client in: AUTH 1 NTLM service=IMAP lip=192.168.2.2 rip=192.168.2.13 Nov 16 23:29:09 SD-Server dovecot: auth(default): client out: CONT 1 Nov 16 23:29:09 SD-Server dovecot: auth(default): client in: CONT 1 TlRM7IIog0ADQAuAAAFASgKAAAAD0AABgATVNTUAABYUEFSQkVKRFNHUlVQUAAAABGACgAAA lNQUNEU= Nov 16 23:29:09 SD-Server dovecot: auth(default): client out: CONT 1 TlRMTVNAAAAFAHgAeAAAAAAAADAA +H1XooTUAACAAAAyZ9yMNkAAdgBlAHIALgBsAG8AACYAJgBOAAAAUwBEAC0AUwBlAHIAYwBh AGwAAwAeAFMAyAC4AbABvsAAAAAGMAYRAAtAFMAZQByAHYAZQBQBAAA= Nov 16 23:29:09 SD-Server dovecot: auth(default): client in: CONT 1 TlRMAYAHwAAAAYABgAlAAAAAwADTVNTUAFQAAAAMAAAAAAAAEAH3ZyprYRPWIAAAAAAcgBkA EkATQBBAEMAWABQAAAAACsAAADAAAAGAABIAqMx1XpiwbAAAHAAcwAcABQNAEEAQwBYAFAAT ABpAHMAYQAgAFMAawBvAHYAZwBhAGAAAAAKIAgUBKAoAAAAPSQBAAAAAAAAAAAJILBz4x4RA Ixsp2rhFi8VB6g== Nov 16 23:29:09 SD-Server dovecot: auth(default): ntlm(?, 192.168.2.13): Username contains disallowed characters Nov 16 23:29:10 SD-Server dovecot: auth(default): client out: FAIL 1 The same account logs in without problems if I use a plaintext password (SSL-encrypted, since plaintext-login is disabled). in dovecot.conf I have the following: auth default { mechanisms = plain digest-md5 cram-md5 ntlm rpa } The authentication is done against a mysql-db, which until now has worked with every client I've tested (except Outlook).

[Dovecot] updated gentoo ebuild provides dovecot-sieve
by Brian G. Peterson 18 Nov '06

18 Nov '06

I'm hoping that there are some Gentoo users on this list who will chime in on a bug that is near and dear to my heart. We've created an updated Gentoo ebuild that adds a sieve USE flag and builds dovecot-sieve if the use flag is enabled. The gentoo bug is here: https://bugs.gentoo.org/show_bug.cgi?id=141743 and the ebuild is available as an attachment to that bug, or as a patch attachment (in case you're not running rc14, or just prefer the look of a unified diff) Any gentoo users on this list are urged to install from the ebuild/patch on the bug, and *report back* on the bug or this list, so that the Gentoo dev will know that it's safe to add this to portage CVS. Thank You. Regards, - Brian

Qmail, when using LDAP, a user can specify delvieryProgramPath, or a .qmail file, to launch something like procmail. Qmail correctly setuid() to the uids set for the user in LDAP, as well as set up the common env vars (HOME, USER, MAILDIR). We moved to Postfix but found that it is quite lacking in the features supported when it comes to "virtual" users. No .forward, and if you set up an alternate transport, they are run as "any user but root, nor postfix, nor the virtual-user's uid". And worse, does not even supply the HOME/MAILDIR values to transport delivery plugin. (Forcing it to getpwnam() or similar). I have an option to make my own setuid program to query LDAP (postmap -q would work), setuid() and call, say, procmail. It has been suggested I can use "maildrop" as it can talk to LDAP. However, I picked "Dovecot" as my pop3/imap program due to an irrational dislike of Courier imap. So, if I tried Dovecot-LDA, would it support the user optionally having a ".forward" file, or perhaps the LDAP attribute deliveryProgramPath, or some other way to filter based on subject/body to sort, and/or forward, mail? If it can use LDAP, will it setuid() to the users uid (as set in LDAP, assuming I cook the LDAP conf entries correctly) when delivering(I'd hope so!) and running external filters? I am still running rc10, which works well but flips out regularly. (Previously mentioned 'too many files open' bug, some leaks in locks) I will upgrade when the LDAP changes are deemed stable.

[Dovecot] two assertion failures
by Mikhail Teterin 18 Nov '06

18 Nov '06

Hello! I was able to overcome the earlier-reported problems (of dovecot treating the standard mailboxes in /var/mail/ as directories) by specifying mail_location (continuing to use the 0.99-era dovecot.conf did not work). Then I started seeing assertion-failures like: file istream-raw-mbox.c: line 499 (istream_raw_mbox_get_body_size): assertion failed: (rstream->mail_size != (uoff_t)-1) these disappeared, when I disabled mmap-access (mmap is limited to 1Gb on FreeBSD/i386), although dovecot-0.99 worked... I can now get to my mail again, but every once in a while the following assertion kills the connection: file mail-transaction-log.c: line 273 (mail_transaction_log_close): assertion failed: (log->files == NULL) Please, advise... Thanks! -mi

[Dovecot] Auth checking also the service
by Alex 18 Nov '06

18 Nov '06

Hello everyone. I'm switching to dovecot from courier-imap and after some problems with Apple Mail client, now everything seems to be fine. The only problem that I have not solved yet is to check also the service (pop3, pop3s, imap, imaps) in the authentication phase. In courier-authlib I do this: MYSQL_SELECT_CLAUSE SELECT username, \ password, \ "", \ 1002, \ 1003, \ '/vmail', \ maildir, \ quota, \ name, \ "" \ FROM mailbox \ WHERE username="$(local_part)@$(domain)" \ AND active=1 \ AND $(service)=1 where $(service) can be pop3, pop3s, imap or imaps. Is it possible to do a similar thing in dovecot? Thank you in advance, Alex

[Dovecot] Help needed
by Ricardo Dias Campos 17 Nov '06

17 Nov '06

Hi. Days ago I sent a message to this list asking for help on a problem that seemed to me to be old: dovecot hangs and dovecot-auth posts log messages like: Nov 16 17:04:39 netuno dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable Nov 16 17:04:42 netuno dovecot: pop3-login: Can't connect to auth server at default: Resource temporarily unavailable Unfortunatelly when this happens the only way to recover is to restart dovecot. After I while I begun to clean the dovecot-auth processes (defunct or not) that remain in the process list and the cycle of running/hunging restart from 1 hang a day until it reaches 1 hang each 10 minutes, when I kill dovecot-auth again. I've seen some days ago some messages related to this problem but they were inconclusive, meaning that they didn't point to a solution. Any help is welcome. Thanks. Ricardo

[Dovecot] LDA Question
by Jeff 17 Nov '06

17 Nov '06

I need some advice about replacing maildrop with the Dovecot LDA. I need to replicate a setup that uses postfix+maildrop+spamassassin. We'll be using Dovecot 1rc13. In the current setup, maildrop reads a file called .mailfilter in each user's folder, then call spamassassin according to the user's preferences. The file is simple, and looks like this -- if ( $SIZE > 20971520 ) { EXITCODE=77 echo "Your email was rejected because it exceeded limit of 20 MB" exit } if ( $SIZE < 26144 ) { exception { xfilter "/usr/local/bin/spamc -u user(a)domain.com" } } exception { to "$DEFAULT/Maildir/" } What is the most straightforward way to have 'Deliver' do the same thing, without changing the way that SA gets called? Apologies in advance if this is a boneheaded question. I've been sorting through Sieve documentation and HOWTOs and I see everything but what I need.

[Dovecot] maildirsize update error?
by Maykel Moya 16 Nov '06

16 Nov '06

According to [1], Trash is a reserverd folder name. When moving a message to it, maildirsize should be update with a negative byte count. If I move a message from any folder to Trash, maildirsize gets two lines, one positive and one negative. The problem is that a user can't move messages to Trash while being overquota because the positive entry goes before the negative. I'm using dovecot-1.0rc14.

[Dovecot] Dovecot tries to create bogus files in /var/mail
by Mikhail Teterin 16 Nov '06

16 Nov '06

After upgrading from 0.99.2 to 1.0rc14, I started seeing log-entries like: Nov 16 12:56:22 corbulon dovecot: IMAP(mksarch): mkdir_parents(/var/mail/mksarch/.imap/INBOX) failed: Not a directory Nov 16 12:56:51 corbulon dovecot: IMAP(anat): open(/var/mail/anat/inbox, O_CREAT) failed: Not a directory Nov 16 12:56:51 corbulon dovecot: IMAP(anat): mkdir_parents(/var/mail/anat/.imap/INBOX) failed: Not a directory And my IMAP client (KMail) shows up error message with "Internal server error". The files in /var/mail/ are just that -- files (in the bad old Unix mbox format), and not directories, why is dovecot treating them as directories? Please advise... Thanks! -mi

[Dovecot] NFSV4?
by Charles Marcus 16 Nov '06

16 Nov '06

Hi Timo, I just read about NFSv4 now being included in SuSE and Redhat Enterprise versions, and although I don't use it myself, wondered how this will impact Dovecot for those using it? Will it make life easier? Or is it even supported currently? Just curious... thanks... -- Best regards, Charles

[Dovecot] 1.0.rc13 released
by Timo Sirainen 15 Nov '06

15 Nov '06

http://dovecot.org/releases/dovecot-1.0.rc13.tar.gz http://dovecot.org/releases/dovecot-1.0.rc13.tar.gz.sig I'll just keep on making new releases now whenever something important is fixed. Hopefully there shouldn't be many left anymore. Most of the bugs fixed in this release were found by stress testing with my imaptest tool (http://dovecot.org/tools/imaptest.c) If you're interested in knowing how perfectly your Dovecot setup works (especially if you're using NFS), you could try the tool yourself also. I still see one crash with mmap_disable=yes, but it's pretty rare. Will see if I get it fixed before v1.0, but it's not that important. + deliver: If we're executing as a normal system user, get the HOME environment from passwd if it's not set. This makes it possible to run deliver from .forward. - Older compilers caused LDAP authentication to crash - Dying LDAP connections weren't handled exactly correctly in rc11, although it seemed to work usually - Fixed crashes and memory leaks with AUTHENTICATE command - Fixed crashes and leaks with IMAP/POP3 proxying - maildir: Changing a mailbox while another process was saving a message there at the same may have caused the changes to not be made into the maildir, which could have caused other problems later..

[Dovecot] 45second delays on log in
by Ben Marsh 14 Nov '06

14 Nov '06

Dear List Members, We have been running Dovecot as an IMAP server for web based access to email for our customers. At the moment, when the server is under load, some users are finding that it takes 45 seconds to log in. I was wondering if any of you guys would have any tips. I would love any information that would help solve or debug this issue. Background information: The server is Debian with kernel 2.4.31. We are running Dovecot 1.0rc6. I have reviewed the change logs and not found any changes pertinent to our situation from rc6 to rc14 (But maybe I am wrong). We have our own auth mechanism. This auth mechanism is the same used across our other products and we haven't had the same delays with the other products. From the information in the various log files the auth mechanism responds almost instantaneously but it still takes a long time for 1 OK Logged in. message to arrive on the screen when using telnet localhost 143 to login. All the mailboxes are stored over NFS. I have taken the step of moving the INDEXES from NFS to a local hard drive using default_mail_env = maildir:%h/mail:INDEX=/spare/%h in the config file. (/spare is a locally attached hard drive). We are using Maildir for our mailboxes so I am told that locking should not be a problem. A mailbox would never be accessed by two machines simultaneously due to the architecture of the system. In order to gain performance increases we also implemented an IMAP proxy between the webmail client and the imap server. This removes delays in all but the first attempt to access webmail. When logging into a user for which login has been verified to take about 45seconds deletion of the large numbers of messages seemed to speed up login for that particular mailbox indicating to me that it was other things that dovecot does after login and before the 1 OK Logged in. message is displayed that takes up all the time. Unfortunately this theory failed when I tried it with other users. I have also analysed the log files. of the 100,000 lines in the log file 49 were messages: Child 12040 (login) returned error 89 54 were messages: imap-login: Master sent reply with unknown tag 18 The actual number at the end of the message changes lots. The frequency of the extended logins would make it extremely unlikely that these messages are the problem. Any help is very much appreciated. Thanks, Ben Marsh

[Dovecot] Question regarding bounce messages on quota full.
by Mustafa A. Hashmi 14 Nov '06

14 Nov '06

Hi all, Using dovecot's LDA (debian backports package: 1.0rc2), users who have exceeded their quota when receiving messages see the message get bounced. This works fine for us, however, the sender is sent a message as follows: -- Start bounce text ERROR This is the Postfix program at host foo.domain.com I'm sorry to have to inform you that your message could not be be delivered to one or more recipients. It's attached below. For further assistance, please send mail to <postmaster> If you do so, please include this problem report. You can delete your own text from the attached returned message. The Postfix program <user(a)foo.domain.com>: Command died with status 11: "/usr/lib/dovecot/deliver" -- End bounce text Is it not possible to specify something a bit more civil for the sender? a "User is over quota" message works much better here. We're already running a script which notifies users when they approach a certain specified % that they're about to exceed quota, however, hoping they all comply is another thing entirely. Any assistance would be much appreciated. Regards, -- Mustafa A. Hashmi mahashmi(a)gmail.com mh(a)stderr.net

[Dovecot] NTLM authentication from Outlook
by Lars Skovgaard 14 Nov '06

14 Nov '06

Hi all I've enabled ntlm authentication in dovecot, and use dovecot sasl in postfix as well. Authentication with ntlm works well from Mac OS X Mail.app, as well as from Outlook Express, but fails with Outlook. Strangely enough, ntml authentication works in Outlook when using smtp (via postfix), but neither from imap or pop3 (both dovecot). As dovecot sasl handles all authentication against a mysql userdb, this strikes me as very strange. I've instructed my clients with Outlook to fetch mail using a ssl- encrypted connection, and to send using ntlm-authentication. This works, but I would like to have ntlm available as an option to all my clients, without forcing them to change mail-clients. I've turned on auth_verbose, auth_debug and auth_debug_passwords, and compared the passwordstring with the one calculated using dovecotpw, and they match. The only odd thing is that the username is returned from Outlook as an all-caps string, so user(a)domain.tld becomes USER(a)DOMAIN.TLD. I don't know if it matters, but I don't think so, as changing the user-login to an all-caps version doesn't solve the problem. Any hints will be most welcome. /Lars

[Dovecot] MacOS X and quota-plugin
by Lars Skovgaard 13 Nov '06

13 Nov '06

Hi all, I've installed dovecot 1.0 rc12 on a MacOS X client system with only a handful of users – all virtual – and would like to enable quotas. I've tried searching the wiki for information on how to do this, but haven't been able to find anything – which is why I turn to the list in hope there's someone out there who can point me in the right direction. I've compiled dovecot without any other authentication than sql and pam, and have enabled ssl, pop3 and dovecot lda (for use with postfix when I get around to it). The installation went smoothly, and dovecot is working great without quota-support. However, when I enable quota- support, the imap child-process crashes. Here's a few lines from the log, slightly altered to protect user-identities: Nov 8 23:05:09 SD-Server dovecot: imap-login: Login: user=<imapuser>, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:09 SD-Server dovecot: child 22662 (imap) killed with signal 11 Nov 8 23:05:09 SD-Server crashdump[22663]: imap crashed Nov 8 23:05:09 SD-Server crashdump[22663]: crash report written to: / Library/Logs/CrashReporter/imap.crash.log Nov 8 23:05:12 SD-Server dovecot: imap-login: Login: user=< imapuser >, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:13 SD-Server dovecot: child 22665 (imap) killed with signal 11 Nov 8 23:05:13 SD-Server crashdump[22666]: imap crashed Nov 8 23:05:13 SD-Server crashdump[22666]: crash report written to: / Library/Logs/CrashReporter/imap.crash.log Nov 8 23:05:16 SD-Server dovecot: imap-login: Login: user=< imapuser >, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:17 SD-Server dovecot: child 22670 (imap) killed with signal 11 Nov 8 23:05:17 SD-Server crashdump[22671]: imap crashed Nov 8 23:05:17 SD-Server crashdump[22671]: crash report written to: / Library/Logs/CrashReporter/imap.crash.log This is what I have done in dovecot.conf to enable quota: protocol imap { mail_plugins = quota imap_quota mail_plugin_dir = /usr/local/lib/dovecot/imap } plugin { #quota = dict:storage=10240 #quota = dirsize:storage=10240 #quota = maildir:storage=10240 #quota = maildir:storage=10240 mysql:/usr/local/etc/dovecot-sql.conf #quota = fs:storage=10240 #quota = fs } As you might guess from the lines under "plugin", I've tried a lot of different combinations. If I enable ANY of the above lines under plugin, the child-processes die upon login. When all have been commented out, there's no more crashing – until I try to see how much space is available, then it crashes again. I've tried adding an extra "quota" field to my mysql userdb to handle quotas, but with the same result. mysql-query looks like this (as described in the wiki): user_query = SELECT home, uid, gid, 'dirsize:storage=' || quota_kb AS quota FROM users WHERE userid = '%u' As with the settings in dovecot.conf, Ive tried various combinations of dict, dirsize and so on, but without any luck. This is what the entries in my crashdump file looks like: Host Name: SD-Server Date/Time: 2006-11-09 00:06:17.151 +0100 OS Version: 10.4.7 (Build 8J135) Report Version: 4 Command: imap Path: /usr/local/libexec/dovecot/imap Parent: dovecot [8370] Version: ???

If nothing big shows up, v1.0 should be out in a couple of weeks. * Renamed default_mail_env to mail_location. default_mail_env still works for backwards compatibility. * deliver: When sending rejects, don't include Content-Type in the rejected mail's headers. * LDAP changes: * If auth binds are used, bind back to the default dn before doing a search. Otherwise it could fail if a user gave an invalid password. * Initial binding at connect is now done asynchronously. * Use pass_attrs even with auth_bind=yes since it may contain useful non-password fields. + passdb checkpassword: Give TCPLOCALIP and TCPREMOTEIP and PROTO=TCP environments to the checkpassword binary so we're UCSPI (and vchkpw) compatible. - mbox handling was a bit broken in rc10 - Using Dovecot via inetd kept crashing dovecot master - deliver: Don't crash with -f "". Changed the default from envelope to be "MAILER-DAEMON". - INBOX wasn't shown with LSUB command if only prefixed namespaces were used. - passdb ldap: Reconnecting to LDAP server wasn't working with auth binds. - passdb sql: Non-plaintext authentication didn't work - MySQL passdb ignored all non-password checks, such as allow_nets - trash plugin was broken

[Dovecot] Deliver: command time exceed limit
by Dominique Feyer 12 Nov '06

12 Nov '06

We use Dovecot on a cluster (10'000 domains, 30'000 account) without any problem with pop/imap. We use Dovecot 1.0 RC10 Now we use virtual transport from postfix for mail delivery. We need the Dovecot LDA for sieve support. We test this solution on some domains with success. But if we change the configuration of all our domains, we have a lots of bounce with this error in postfix log: postfix/pipe[24573]: 4F6D7CF11: to=<info(a)XXXX.com>, relay=dovecot, delay=1200, status=bounced (Command time limit exceeded: "/usr/local/dovecot/libexec/dovecot/deliver") If I watch the deliver activity with ps/awk/watch, I see that if deliver duration time exceed some seconds, the deliver process stay in memory but do nothing. Here a strace output of this case: Process 349 attached - interrupt to quit gettimeofday({1161965973, 768478}, {0, 0}) = 0 poll( Strace output nothing before the SIGKILL from postfix (command time exceed 1200 second), the end of the strace: [{fd=5, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=9, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 2, 2147483647) = -1 EINTR (Interrupted system call) +++ killed by SIGKILL +++ I'm not sure is this problem has a relation with our deliver problem. But in the deliver log /var/log/dovecot/deliver, I have a lots of message: deliver(info(a)labomex.com): 2006.10.27 18:29:28 Error: file_dotlock_replace(/var/mail/labomex.com/mails/info/.dovecot.lda-dupes) failed: No such file or directory deliver(info(a)labomex.com): 2006.10.27 18:29:28 Error: rename(/var/mail/labomex.com/mails/info/.dovecot.lda-dupes.lock, /var/mail/labomex.com/mails/info/.dovecot.lda-dupes) failed: No such file or directory Our dovecot.conf (lda parts): protocol lda { postmaster_address = postmaster(a)clm.net4all.ch #hostname = mail_plugins = cmusieve mail_plugin_dir = /usr/local/dovecot/lib/dovecot/lda sendmail_path = /usr/sbin/sendmail auth_socket_path = /var/run/dovecot/auth-master log_timestamp = %Y.%m.%d %H:%M:%S%t log_path = /var/log/dovecot/deliver info_log_path = /var/log/dovecot/deliver.info } We use on UID/GID per domain so every account of a domain use the same UID/GID.

[Dovecot] Writing to mail directory
by Gerard Seibert 12 Nov '06

12 Nov '06

FreeBSD 6.1 Dovecot 1.0.rc12 Using Dovecot as an LDA produces this error message: // START ERROR MESSAGE // deliver(gerard): Error:open(/var/mail/.temp.scorpio.seibercom.net.812.03034e3c3c1ab1c8) failed: Permission denied deliver(gerard): Error: file_lock_dotlock() failed with mbox file /var/mail/gerard: Permission denied // END ERROR MESSAGE// Actually, there are dozens of similar messages for all of my accounts. One example is enough to see what I am referring to. I am using Postfix for my mail-server. If I change the permissions on the directory to '1777' the error goes away and everything seems normal. The problem is that I should not have to do that and I do not understand what the problem is. Has anyone else experienced this phenomena and come up with a solution? Thanks! -- Gerard "Off list mail from *.gmail.com is rejected/deleted unseen. Don't waste your time."

[Dovecot] Using Substring Width with Mailhome Variables
by Matthew Fisch 12 Nov '06

12 Nov '06

Hello All, I am currently running Dovecot v1.0.rc13 from dovecot-1.0-0_31.rc13.fc5.at.i386.rpm on Linux HOST 2.6.17-1.2157_FC5 #1 Tue Jul 11 22:55:46 EDT 2006 i686 i686 i386 GNU/Linux. I am trying to install Dovecot in a large mail hosting environment and running into troubles. I have specified my mail home in dovecot.conf as follows: default_mail_env = maildir:/mnt/fileserver/maildir/%0.1d/%1.1d/%d/%n I've also tried among other variations: default_mail_env = maildir:/mnt/fileserver/maildir/%0d/%1.1d/%d/%n The expected behavior here, is to resolve this to: /mnt/fileserver/maildir/a/b/abc.com/user However, Dovecot seems to resolve this to: /mnt/raidzone01/maildir/abc.com/bc.com/abc.com/user/ It appears to me using 'width' with a substring does not work as is advertised on http://wiki.dovecot.org/Variables. This page does describe I need to be using 1.0-tests, what is 1.0-tests? I've also tried the default FC5 package: 1.0-0.beta8.2.fc5. Did I misunderstand the syntax? Am I using the wrong version? I won't be able to use dovecot without support for this feature as I am hosting many thousands of domains and know not how else to resolve them all. Thanks for all your time in advance, Matt Matthew Fisch Your-Site.com

[Dovecot] RFC 2822 - message-id
by Tom Allison 10 Nov '06

10 Nov '06

I was porting some email from one imap server location to another and ran into a feature of something. One of them writes message-id as 'Message-Id' and the other writes it as 'Message-ID'. Because of this, all the messages are forever different. All mail is delivered from postfix and will be in the future. But I'm asking which of these syntaxes is correct or if there is a right/wrong way of writing the headers? RFC2822 doesn't come right out and say it, but all the examples therein are "Message-ID". RFC 822 says they are all the same. Both?

[Dovecot] Qpopper migration?
by Steve Goodman (lists) 09 Nov '06

09 Nov '06

Hello, As this is my first post to the list, first and foremost I'd like to thank Timo for writing great software; we've successfully moved to Dovecot for over 10,000 users from UW-IMAP and get great performance. On our overloaded staff POP3/IMAP server, we are looking at replacing qpopper+uw-imapd with dovecot, as an interim before moving them to the main Unix mailstore. The system is primarily POP3, with a small number of heavy IMAP users causing the system grief. There are a large number of POP3 users who leave messages on the server. What I want to ensure doesn't happen is that they are forced to download them again. Do I need to add anything specific in the pop3_uidl_format or am I barking up the wrong tree? Kind Regards, Steve

[Dovecot] Quota without dovecot LDA
by Riccardo Bini 08 Nov '06

08 Nov '06

Hi all, I use dovecot with maildir quota plugin + qmail + vpopmail but not dovecot LDA. My dovecot configuration: default_mail_env=maildir:~/Maildir:INDEX=/var/cache/dovecot/indexes/%h/%u:CONTROL=/var/cache/dovecot/control/%h If CONTROL env is set the maildirsize file is stored in /var/cache/dovecot/control/ but I use vpopmail as LDA. It's possible to add a setting in dovecot.conf to specify if dovecot LDA is active?? This is my pseudo-patch: src/plugins/quota/quota-maildir.c static const char *maildirsize_get_path(struct mail_storage *storage) { if (lda_enable) { return t_strconcat(mail_storage_get_mailbox_control_dir(storage, ""), } else { bool is_file; return t_strconcat(mail_storage_get_mailbox_path(storage, "", &is_file), "/"MAILDIRSIZE_FILENAME, NULL); } } dovecot.conf: lda_enable = no Ciao Rick

[Dovecot] How to give system and virtual users their own mail_location?
by Egbert Jan 08 Nov '06

08 Nov '06

Hi all. Now hopefully as a new thread because I still have this question. Apologies to Geert and Timo for my misbehaviour...(repling to the list and changing the subject). I hace Dovecot rc12 working on Mandriva 2007.0 now for system accounts and virtual accounts both imap and imaps can be used. Th problem now is that I cannot use both types of user at the same time. The 'mail_location = ' strings are very different: Real system users have their Maildir in /home/%u/Maildir/ but virtual users have their maildir in /home/virtual/%d/%n/. How can tell dovecot to use the first for /etc/passwd clients and second for mysql authenticated clients? Just adding two private namespaces does not work. That is for ONE user having more mailbox locations, isn't it? Thanks for any hints! Egbert Jan (NL)

[Dovecot] L4 probes..
by Jorgen Lundman 08 Nov '06

08 Nov '06

Probably a special case here, but everytime the L4 probes the port, a line as added to the log. This gets a bit noisy. If a random IP connects, I'd want to see it, but maybe it would be nice to have the option to silence the log entry from certain hosts. For now I patch it locally, but without any .conf finesse. For example: Nov 8 10:55:24 corppop01 dovecot: [ID 107833 mail.info] pop3-login: Disconnected: rip=172.16.253.5, lip=172.16.253.128, TLS handshake Nov 8 10:58:00 corppop01 dovecot: [ID 107833 mail.info] pop3-login: Aborted login: rip=172.16.253.5, lip=172.16.253.128 -- Jorgen Lundman | <lundman(a)lundman.net> Unix Administrator | +81 (0)3 -5456-2687 ext 1017 (work) Shibuya-ku, Tokyo | +81 (0)90-5578-8500 (cell) Japan | +81 (0)3 -3375-1767 (home)

[Dovecot] deliver feature request (filter)

I'm using maildrop for delivery, because I want to filter through spamassassin before delivery. Maildrop makes that trivial. It seems deliver can pipe (one way) to a command, but what is needed is to pipe: deliver -> spamd -> deliver which is what the maildrop xfilter does.

I just installed a limited test of RC10 last night. So far, all is great except for errors being logged for one user (out of about 150 users total). This one user has not yet complained or anything, but the log file has repeated entries of the following format for him (host and username changed to protect the guilty/innocent): Oct 24 06:13:02 mail dovecot: IMAP(username): file mbox-sync-rewrite.c: line 405 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) Oct 24 06:13:02 mail1 dovecot: child 18235 (imap) killed with signal 6 I find it most interesting that only 1 out of 150+ users is getting this error... And again, no complaints from the user. Setup is: wu-imap mbox files in /var/spool/mail (exported via NFS, but local to the dovecot server). Mail in ~/mail/ (NFS mount, foreign to devecot server). Indexes in /var/dovecot/indexes (local to dovecot server with no NFS at all). -- Eric Rostetter The Department of Physics The University of Texas at Austin Go Longhorns!

[Dovecot] rc13 soon
by Timo Sirainen 07 Nov '06

07 Nov '06

I think I'll just start making new releases whenever I've fixed something important. You'll have a while to report more bugs and then I'll make rc13 release, maybe in about 5 hours or maybe tomorrow. I updated already the nightly snapshot if you want to test the upcoming rc13. Changes so far: + deliver: If we're executing as a normal system user, get the HOME environment from passwd if it's not set. This makes it possible to run deliver from .forward. - Older compilers caused LDAP authentication to crash - Dying LDAP connections weren't handled exactly correctly in rc11, although it seemed to work usually - Fixed crashes and memory leaks with AUTHENTICATE command - Fixed crashes and leaks with IMAP/POP3 proxying

[Dovecot] 1.0rc10 proxy memory usage problem
by Laurent Papier 07 Nov '06

07 Nov '06

Hi, I have a rather large dovecot setup (4 proxy only servers and 21 IMAP/POP3 servers) in production for 3 days now. The memory usage on my proxy servers only grows over time. It looks like a memory leak somewhere in dovecot. I have a RRD graph available on demand. Any advise on the configuration ? Timo, I have strace a process before the manual restart. If it can help just ask for. My configuration : Linux kernel 2.6. I use MySQL as authentication back-end. # dovecot --version 1.0.rc10 # dovecot --build-options Build options: ioloop=epoll notify=dnotify ipv6 openssl SQL drivers: mysql Passdb: checkpassword pam passwd passwd-file shadow sql Userdb: checkpassword passwd prefetch passwd-file sql static ----- config ----- protocols = pop3 imap disable_plaintext_auth = no ssl_disable = yes login_process_size = 128 login_process_per_connection = no login_processes_count = 16 login_max_connections = 512 login_greeting = ready auth_cache_size = 32768 auth_cache_ttl = 1800 auth_worker_max_count = 30 auth default { mechanisms = plain # Userdb settings are not used with proxy but there need to be something. userdb static { args = static uid=5000 gid=5000 home=/dev/null } passdb sql { args = /etc/dovecot-mysql.conf } user = root count = 1 } -- Laurent Papier

[Dovecot] rc12 dovecot-auth core dump with ldap
by Chris Wakelin 07 Nov '06

07 Nov '06

Hi, I've got a core dump during initialisation when I use 1.0.rc12 and LDAP with authenticated binds in Solaris. It worked OK in 1.0.rc10. Here's the non-commented entries in dovecot-ldap.conf - some of which are probably redundant :) :- hosts = xxx.yyy.rdg.ac.uk auth_bind = yes auth_bind_userdn = "cn=%n,cn=users,dc=xxx,dc=yyy,dc=rdg,dc=ac,dc=uk" ldap_version = 3 base = "dc=xxx,dc=yyy,dc=rdg,dc=ac,dc=uk" deref = never scope = subtree user_filter = (&(objectClass=User)(sAMAccountName=%n)) pass_filter = (&(objectClass=User)(sAMAccountName=%n)) Strangely, it crashes in a different place when I don't define the scope, so I'm guessing it's something to do with reading parameters. backtrace with "scope = subtree" : #0 0x1ec94 in db_ldap_init ( config_path=0x5bc08 "/opt/RDGdovect/etc/dovecot-ldap.conf") at db-ldap.c:661 661 if (*conn->set.user_global_gid == '\0') (gdb) bt #0 0x1ec94 in db_ldap_init ( config_path=0x5bc08 "/opt/RDGdovect/etc/dovecot-ldap.conf") at db-ldap.c:661 #1 0x246e8 in passdb_ldap_preinit (auth_passdb=0x5bbe8, args=0x5bc08 "/opt/RDGdovect/etc/dovecot-ldap.conf") at passdb-ldap.c:486 #2 0x2328c in passdb_preinit (auth=0x5b838, driver=0xffbefec0 "ldap", args=0x0, id=332176) at passdb.c:169 #3 0x17648 in auth_preinit () at auth.c:45 #4 0x1ff0c in drop_privileges () at main.c:195 #5 0x2024c in main (argc=0, argv=0xffbefb54) at main.c:319 and with scope left commented out: #0 0xff0cf600 in strcasecmp () from /usr/lib/libc.so.1 (gdb) bt #0 0xff0cf600 in strcasecmp () from /usr/lib/libc.so.1 #1 0x1df58 in scope2str (str=0x0) at db-ldap.c:116 #2 0x1ec4c in db_ldap_init ( config_path=0x5bc08 "/opt/RDGdovect/etc/dovecot-ldap.conf") at db-ldap.c:648 #3 0x246e8 in passdb_ldap_preinit (auth_passdb=0x5bbe8, args=0x5bc08 "/opt/RDGdovect/etc/dovecot-ldap.conf") at passdb-ldap.c:486 #4 0x2328c in passdb_preinit (auth=0x5b838, driver=0xffbefec0 "ldap", args=0x0, id=332176) at passdb.c:169 #5 0x17648 in auth_preinit () at auth.c:45 #6 0x1ff0c in drop_privileges () at main.c:195 #7 0x2024c in main (argc=0, argv=0xffbefb54) at main.c:319 If I don't define "deref" then I get an error in the dovecot log (but no crash) :- dovecot: Nov 07 12:36:45 Error: auth(default): LDAP: Unknown deref option 'subtree' I'll keep digging and see if I can find the cause, but has anybody else seen this?

[Dovecot] suspected bug in dovecot-ldap setup?
by Pedro Venda 07 Nov '06

07 Nov '06

Hi everyone, [first post: long and boring. beware!] I've been working on a virtual multidomain MX server with pop3 access. Accounting for users/domains is done via OpenLDAP with the Jamm[1] schema and dovecot is 1.0rc10 (dovecot-1.0-0_27.rc10.el4.at fetched as RPM from atrpms.net for CentOS 4.4). I intended to have authenticated binds but there was a problem with the user_filter directive being ignored: user_filter = (&(objectClass=JammMailAccount)(mail=%n@%d)(accountActive=TRUE) (delete=FALSE)) dovecot: Oct 26 16:20:58 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=::ffff:192.168.0.5 rip=::ffff:192.168.0.69 resp=<hidden> dovecot: Oct 26 16:20:58 Info: auth(default): ldap(dave@info.test,::ffff:192.168.0.69): bind search: base=o=hosting,dc=example,dc=com scope=subtree filter= **(&(objectClass=posixAccount(uid=dave(a)info.test))** dovecot: Oct 26 16:20:58 Info: auth(default): ldap(dave@info.test,::ffff:192.168.0.69): unknown user dovecot: Oct 26 16:20:59 Info: auth(default): client out: FAIL 1 user=dave(a)info.test dovecot: Oct 26 16:20:59 Info: imap-login: Disconnected: user=<dave(a)info.test>, method=PLAIN, rip=::ffff:192.168.0.69, lip=::ffff:192.168.0.5, TLS (nevermind the data, it's test only) As you can see from the info file, the search filter used was being (&(objectClass=posixAccount(uid=dave(a)info.test)) and not (&(objectClass=JammMailAccount)(mail=dave(a)info.test)(accountActive=TRUE) (delete=FALSE)). I sorted this out by trying to enable auth_bind_userdn: auth_bind_userdn = mail=%n@%d,jvd=%d,o=hosting,dc=example,dc=com Now, the login worked well and the debug info is as follows: dovecot: Oct 27 12:01:48 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip=::ffff:192.168.0.5 rip=::ffff:192.168.0.69 resp=AGRhdmVAaW5mb y50ZXN0AFRlbXAuMTIz dovecot: Oct 27 12:01:48 Info: auth(default): client out: OK 1 user=dave(a)info.test dovecot: Oct 27 12:01:48 Info: auth(default): master in: REQUEST 1 10634 1 dovecot: Oct 27 12:01:48 Info: auth(default): ldap(dave@info.test,::ffff:192.168.0.69): base=o=hosting,dc=example,dc=com scope=subtree filter=(&(objectClass=JammMailAccount)(mail=dave(a)info.test) (accountActive=TRUE)(delete=FALSE)) fields=mailbox dovecot: Oct 27 12:01:48 Info: auth(default): master out: USER 1 dave(a)info.test mail=info.test/dave/ uid=5000 gid=5000 (nevermind the debug data, passwords, etc. it's test only) In this case, the search filter is ok: (&(objectClass=JammMailAccount)(mail=dave(a)info.test)(accountActive=TRUE) (delete=FALSE)) So aparently, the auth_bind_userdn directive that supposedly adds a performance gain by sparing one bind request, seems to interfere with the user_filter directive. I suspect this might be a bug, so here's my report. Is this a new issue? Thanks for surviving this far through this post, Best regards, Pedro Venda.

[Dovecot] Store outgoing mail in users mailbox
by Mark Ruys 07 Nov '06

07 Nov '06

This might be a MTA question, but because I use Dovecot as an LDA, maybe some can help me here. Our users would like that outgoing mail is automatically saved in some folder, say Sent. We use Postfix with virtual domains, Maildir and Dovecot+Sieve as LDA. Outgoing mail is relayed by our imap-server (with authentification of course, no open relay). Most people seem to advice Postfix sender_bcc_maps and Dovecot's deliver with the -m argument. But I can't get it work. I tried: In master.cf: dovecot-archive unix - n n - - pipe flags=DRhu user=mailowner:mailowner argv=/usr/libexec/dovecot/deliver -d ${recipient} -m Sent In main.cf: sender_bcc_maps = hash:/etc/postfix/sender_bcc_map In sender_bcc_map: tester(a)ruijs.cc dovecot-archive: But that doesn't work. It looks like "dovecot-archive:" should be a real email address, not a transport (this give an idea of my Postfix knowledge ;). Then I tried: In sender_bcc_map: tester(a)ruijs.cc tester+archive(a)ruijs.cc But I don't think Dovecot's LDA supports plus addressing. So my question is, has anyone here done a similar thing in a similar setting. If so, how did you configure it.

[Dovecot] Upgrade from RC7 to RC10 didn't go too well...
by Ivo Truxa 06 Nov '06

06 Nov '06

I have the same problem after upgrading to RC10. Did you find a solution? Should I update to RC11 or rather downgrade back to an earlier version? Thanks, Ivo Truxa >>>>>>> original message >>>>>>> Hi, On the weekend I tried to upgrade from RC7 to RC10. Clearly, I have to change some things before I can do this. What does it take to get to RC10? As is, my mail client got an error trying to list messages in /INBOX (via IMAP) and the mail.err log shows the following messages: Oct 29 10:27:32 siona dovecot: IMAP(archangel): open(/var/mail/archangel/inbox, O_CREAT) failed: Not a directory Oct 29 10:27:32 siona dovecot: IMAP(archangel): mkdir_parents(/var/mail/archangel/.imap/INBOX) failed: Not a directory Oct 29 10:27:32 siona dovecot: IMAP(archangel): open() failed with subscription file /var/mail/archangel/.subscriptions: Not a directory My dovecot.conf includes default_mail_env = mbox:/var/mail/%u And other then enabling SSL, I've got a pretty vanilla configuration (e.g. nothing in the IMAP section at all, no odd namespaces...) /var/mail/archangel is an mbox file, why is dovecot trying to open files under there? I know at least part of the discussion has happened on the list before so I'm sorry for duplicating other questions. My TODO is about ten km long so I hope someone can at least give me a couple good pointers. Thanks in advance! -- Dominic Lepiane The IRMACS Centre

[Dovecot] v1.0 plans, rc11 tomorrow
by Timo Sirainen 06 Nov '06

06 Nov '06

As you can probably guess from my today's burst of activity, I'm no longer extremely busy. Actually it looks like for the next 3-4 weeks I don't have anything especially time consuming to do. So it's time to get Dovecot v1.0 released :) I've now read all the mails from this list again, and it looks like pretty much the only problems with rc10 was the mbox assert crash, which is now fixed. My TODO contains: v1.0 blocker: - inetd logins are broken? I should look more into this.. I only remembered this just now while writing this mail. New non-v1.0 blockers: - trash plugin is apparently broken? - mbox_min_index_size != 0 causes Invalid new transaction log sequence (4 >= 4) The old preferrably-fixed-for-v1.0 items are: - ldap auth is leaking memory? maybe not, maybe it's something else. - master leaks log fds with kqueue. I don't have a machine to test this on. Could someone give me an account in some BSD system for a while to test this? Anyway, I'll most likely release rc11 tomorrow, but it would be nice if you tested today's CVS snapshot already to see if I accidentally broke something. :) http://dovecot.org/nightly/dovecot-latest.tar.gz Oh and one thing that I wanted for Dovecot v1.0 was nice documentation. I think the current wiki is a bit chaotic. I started http://wiki.dovecot.org/NewIndex a long time ago. Maybe I should finish it finally and put it as the new main index..

[Dovecot] Auto-expire messages in a folder
by Mike Cisar 05 Nov '06

05 Nov '06

I have a Fedora 5 server running Dovecot (currently 1.0 rc10). The spam filter (amavis) automatically tags email (using plussed addressing) such that messages flagged as spam are sorted into a "spambox" folder by procmail. Seemed like a good idea at the time, but because of some legacy issues with filesystem quota also being in place, combined with most users connecting with POP3 rather than IMAP... spam doesn't stay in their inbox, they don't check their spambox and they are very quickly over quota. What I would like to do is stick with the "spambox" folder idea, but have any messages in that folder which are older than a certain number of days deleted automatically. Could this be done by Dovecot? If so how would dovecot know to visit all the user's mailboxes to do it... or would it only be able to do so when a user logged in via IMAP (as opposed to POP3)? If not, is anyone aware of a script that I could run in nightly maintenance to do a cleanup pass on all the mailboxes? I know there are any number of ways that this could be accomplished but I would like to do it as much within my existing framework as possible... sendmail/procmail/amavis on the delivery side, dovecot in the middle, horde/imp for webmail and whatever email client the end users have (likely Outlook/Outlook Express for the most part)... all pretty generic, standard mailbox formats... nothing fancy like data stored in mySQL or anything like that. As everyone encounters, the more parts you change, the more other parts you have to fix to be compatible with the changes :-) Obviously I would like the solution to also be as feature rich as I can at the same time (might as well wish for it all right :-). Maybe for the sake of the POP3 folks it would also be nice to generate a once-daily email with the names, subjects of the messages in the folder saying "here's what is in your spam folder, please log in to webmail to manage your spam" (and in a perfect world some sort of link to click on which could move the message from the spambox back into the inbox). Does anyone have any solutions they can share that run within a similar framework to what I have set up? The thing that I need in the immediate term is to purge the spam folder automatically, the mid-term goal is to evolve that into a sort of spam-processing center/solution for the users. Thanks for any suggestions! Cheers, >>>>> Mike <<<<<

[Dovecot] ~/.maildir preferable to %h/Maildir and ~/Maildir?
by Jeff Kowalczyk 05 Nov '06

05 Nov '06

I have a recently deployed dovecot server and am readying another. Upon updating to rc12, I note the following change in the default dovecot.conf file: -default_mail_env = mbox:/var/spool/mail/%u:INDEX=/var/dovecot/%u +mail_location = maildir:~/.maildir Integrating this change to my local dovecot.conf: # formerly used default_mail_env = maildir:%h/Maildir # dovecot default mail_location = maildir:~/.maildir mail_location = maildir:~/Maildir With unix users of the form: myuser:x:505:100:My User:/home/myuser:/sbin/nologin each having ~/Maildir, should I: 1) use the ~/.maildir form over ~/Maildir. 2) use the ~ instead of %h 3) do anything for dovecot's benefit (reindex, etc.) besides a per-user 'mv ~/Maildir ~/.maildir' if 1). I came straight from an ancient sendmail mbox setup to dovecot, so I want to do things the best-pracitce IMAP/dovecot way. Thanks.

[Dovecot] Sending email using IMAP
by Marc Perkel 05 Nov '06

05 Nov '06

This is something for after the 1.0 release but I think it's important and I'm going to try to figure out how to make it happen. I'd like to see some way to pass outgoing email from Thunderbird back to dovecot through some new command that we would have to make up. Email would be sent back over the IMAP connection and when Dovecot gets it dovecot would hand it off to an SMTP server that would deliver it. If a crude experimental spec can be written I'll try to find someone on the Thunderbird side to write some sort of module to talk to it. The reason for this is that I think that the elimination of SMTP from the client is a big step to control spam. The idea being that if IMAP can transfer outgoing mail the SMTP wouldn't be necessary for clients and we can block port 25 on windows machines and viruses can't send email. And the virus wouldn't have access to the IMAP password so viruses can't authenticate to send mail. So - the key question is - what would it take to create an outgoing spec for sending email over IMAP? Like to see something clean and simple.

[Dovecot] MySQL Configuration
by Gerard Seibert 04 Nov '06

04 Nov '06

Dovecot 1.0.rc10 FreeBSD 6.1 This is probably a dumb question; however, I have never let a little thing like that bother me in the past. In the 'dovecot.conf' file there are the follow two sections: # SQL database passdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /usr/local/etc/dovecot-sql.conf } userdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /usr/local/etc/dovecot-sql.conf } I keep the 'users' and their respective 'passwords' in the same MySQL database. I am not sure why I wouldn't. Therefore, would it not make more sense to have just one MySQL configuration line in the 'dovecot.conf' file rather than two, or am I missing something here? -- Gerard Seibert gerard(a)seibercom.net Laws are like sausages.

[Dovecot] auth-req-handler.c adds spurious tab
by Chris Laif 04 Nov '06

04 Nov '06

If the auth backend (postgresql in my case) returns extra fields, and all of these extra_fields begin with 'userdb_', the auth_callback functions adds an unwanted extra tab at the end of the response: auth(default): client out: OK^I8^Iuser=foo@bar^I This extra tab at the end confuses exim's dovecot-auth handler (the exim-dovecot auth handler does not correctly count the number of returned fields then (side note: the code on exim's side should probably be cleaned up as well)). A quick fix is attached below.

[Dovecot] Server-side mail archiving - possible dovecot lda feature?
by Charles Marcus 03 Nov '06

03 Nov '06

Hi Timo, I have a question on the feasibility of adding the capability directly in dovecot LDA (or maybe this wouldn't be the correct place?) to provide a server-side mail archiving feature. What I'd like is a simple way to define a maildir, ie: vmail/archive/$user/Inbox and vmail/archive/$user/Inbox.Sent And then have the dovecot LDA deliver a copy of all mail (incoming and outgoing) to this archive folder. Is the dovecot LDA the best place for this to go? Or would an entirely new plug-in be more appropriate? My boss may be willing to pay to have this capability added. I have investigated other third party solutions, but I would prefer something that is tightly integrated with dovecot. I look forward to your response... -- Best regards, Charles

by LeVA 03 Nov '06

03 Nov '06

Hi! I'm using rc10, but had this problem with previous releases too. Not sure if this is a dovecot problem, but I can not think of anything else. The mail downloading with pop3 is ~very slow, approx. 20 Kbyte / sec. no matter how many mails I've got in my mailbox, or how big are the mails. My ISP provides me a dedicated 100mbit line, and everything else works as fast as expected eg. http, ftp, scp... The OS is OpenBSD 3.9-stable and the system is not under heavy load at all. I've tried to turn off TLS but there was no change. Is the pop3 protocol this slow by design or there is something wrong with my setup? Thanks! Daniel -- LeVA

[Dovecot] CRAM-MD5 auth broken with postgresql passdb?
by Chris Laif 03 Nov '06

03 Nov '06

I'm currently experiencing a problem which has already been described by Jonathan in http://www.dovecot.org/list/dovecot/2006-August/015501.html If I use CRAM-MD5 auth with passwd-file as a backend (Thunderbird client) everything works fine (MD5-hashes have been shortened for readability): dovecot: auth(default): password(bob(a)foo.bar,10.0.0.123): Credentials: f12c884ba3cc82.. dovecot: imap-login: Login: user=<bob(a)foo.bar>, method=CRAM-MD5, rip=10.0.0.123, lip=10.0.0.234 My passwd file contains a line like this: bob@foo.bar:{HMAC-MD5}f12c884ba3cc82.. If I change to postgresql-based passdb, PLAIN auth works (!) and CRAM-MD5 does not work: dovecot: auth(default): sql(bob(a)foo.bar,10.0.0.123): query: SELECT 'bob(a)foo.bar' AS user, '{HMAC-MD5}f12c884ba3cc82..' AS password dovecot: auth(default): password(bob(a)foo.bar,10.0.0.123): Credentials: dovecot: auth(default): cram-md5(bob(a)foo.bar,10.0.0.123): password mismatch Please note the ultra-simple SELECT-statement (I've tried other combinations as well - no success). sql.conf setting is "default_pass_scheme = HMAC-MD5". Dovecot version 1.0.rc10. In the postgresql-based example the "Credentials:" variable is empty. I wonder if this is a bug in dovecot. Please let me know if you need any further information to resolve this issue. Thanks, Chris (As a side not I still do not understand how CRAM-MD5 auth is able to work without a plain text password, but that's another story. If it works with an HMAC-MD5 hash in a passwd-file backend it should work with the postgresql-db backend as well.)

[Dovecot] quota question
by Jakob Curdes 03 Nov '06

.. maybe a silly one, but how does the user get notified when he is over quota? Did not find anything in the docs. Is there a general IMAP way to do this or what else ? Yours JC

Hello, I found this thread: http://www.dovecot.org/list/dovecot/2006- September/015955.html and have successfully compiled and installed cmusieve plugin. How does one test to make sure its being loaded? It's not parsing my sieve files in the users homes and I'd like to first check if the plugin is being loaded, since I am getting no errors about it. Thanks

[Dovecot] Postfix + Dovecot LDA Problem
by Steven F Siirila 03 Nov '06

03 Nov '06

I am having a problem setting up a server to handle e-mail in a way in which it had always done traditionally, but with Postfix+Dovecot LDA. Here's a rundown... Solaris 9 Postfix 2.3.3 Dovecot 1.0.rc10 Postfix non-defaults (postconf -n): alias_maps = dbm:/etc/mail/aliases command_directory = /opt/postfix/sbin config_directory = /etc/opt/postfix daemon_directory = /opt/postfix/libexec debug_peer_level = 2 html_directory = no inet_interfaces = $myhostname mail_owner = postfix mailbox_command = /opt/dovecot/libexec/dovecot/deliver -f "$SENDER" mailq_path = /opt/postfix/bin/mailq manpage_directory = /opt/postfix/man masquerade_domains = tc.umn.edu masquerade_exceptions = root mydestination = $myhostname mynetworks = 127.0.0.0/8, ... (omitted) myorigin = $mydomain newaliases_path = /opt/postfix/bin/newaliases queue_directory = /var/spool/postfix readme_directory = no relayhost = [omitted.tc.umn.edu] sample_directory = /etc/opt/postfix sendmail_path = /opt/postfix/sbin/sendmail setgid_group = postdrop smtpd_client_restrictions = permit_mynetworks, reject unknown_local_recipient_reject_code = 550 This works just like our old MTA, with one exception: sending e-mail to addresses within our domain (@tc.umn.edu) requires us to specify the @tc.umn.edu -- otherwise it is rejected with a message like alias(a)host.tc.umn.edu does not exist. I want such messages to be relayed to the relayhost. When I set mydestination to null, and luser_relay = $user@$domain the message goes into a black hole (I never get the message, nor do I get an NDN.) I am posting this to both the Dovecot and Postfix lists since I'm not sure where the fault lies, configuration- or software-wise. Thanks in advance for any helpful tips. -- Steven F.

When I try without any options I get: dovecot-config not found from /usr/src/dovecot-sieve, use --with-dovecot=PATH to give path to compiled Dovecot sources I tried using "./configure --with-dovecot=/usr/libexec/dovecot" but get the same problem.

[Dovecot] making dovecot and exim write to one log
by Zbigniew Szalbot 02 Nov '06

02 Nov '06

Hello, I am looking for some advice. I am trying to force dovecot to run to the same log as exim does. In dovecot.conf I put the exim log path /var/log/exim/mainlog. I restarted dovecot and the process worked fine. However at midnight exim log file is rotated and since then dovecot stops logging to this log. In syslog.conf I put: mail.* /var/log/exim/mainlog And in newsyslog.conf I have: /var/log/exim/mainlog mailnull:mail 640 60 * @T00 Z I used to have an N flag next to Z but after reading the man I realized that its job is not to inform other processes about log creation. My qeustion is how do I set up things that dovecot and exim happily write to one log without having to restart dovecot at midnight? I am fairly new to FreeBSD which I use so I beg your patience with me. Thanks! -- Zbigniew Szalbot

Re: [Dovecot] deliver + quota failure
by Mark Ruijs 02 Nov '06

02 Nov '06

I investigated the deliver with quota's bug a little more (rc10, mysql, virtual domains, maildir). My log files reads: deliver(test(a)ruijs.cc): Info: msgid=<000f01c6fac1$bd4e8670$8801a8c0@Moskou>: save failed to INBOX deliver(test(a)ruijs.cc): Info: sieve runtime error: Keep: Generic Error deliver(test(a)ruijs.cc): Info: msgid=<000f01c6fac1$bd4e8670$8801a8c0@Moskou>: save failed to INBOX deliver(test(a)ruijs.cc): Error: open(ruijs.cc/test//.temp.in2sports2.vianetworks.nl.13210.72d247ac698d0019) failed: No such file or directory deliver(mark(a)ruijs.cc): Info: msgid=<dovecot-1162066721-407295-0(a)in2sports2.vianetworks.nl>: saved mail to Junk Dovecot tries to deliver, but notices quota exceeded. I don't think Sieve is playing a role here - I added Sieve before I encountered the problem. Two problems: 1) The .dovecot.lda-dupes can't be written (that's what the open...failed notice is about). 2) The Quota Exceed mail seem to contain mal-formed headers (that's why it the notice-mail ends in my junk-folder). Digging into deliver.c, I noticed that auth_client_put_user_env() changes the HOME environment from /var/mail (which is ok), to ruijs.cc/test/ (which is the maildir, relative to /var/mail). And then fopen fails (see the trace below). So I think that the code auth_socket = getenv("AUTH_SOCKET_PATH"); if (auth_socket == NULL) auth_socket = DEFAULT_AUTH_SOCKET_PATH; ret = auth_client_put_user_env(ioloop, auth_socket, destination, process_euid); if (ret != 0) return ret; home = getenv("HOME"); if (home != NULL) { /* If possible chdir to home directory so core file could be written. If it fails, don't worry. */ (void)chdir(home); is the key. Should the chdir be done *before* the call to auth_client_put_user_env()? I'm not familiar with the internal workings of the Dovecot LDA, so I won't suggest a proper fix. Who will. As for the mal-formed headers, I'll take a look at it later.

[Dovecot] INBOX un-subscribable (is that a word?)
by Jim Horner 02 Nov '06

02 Nov '06

I am trying to get open-xchange installed and working (which after two days might be futile). In doing this I noticed that no email client can subscribe to INBOX. I'm using rc10 and my namespaces are the following. 99% of the email clients ignore the inability to subscribe to INBOX and display all the folders underneath anyway which is why I've never noticed this issue... however, open-xchange is not in that camp and only displays messages in INBOX. All folders are in the subscriptions file including INBOX but all email clients always list INBOX as not subscribed to. COMPANY are ROOTMAIL are share folders with ACLs in /etc/dovecot/acl and those top folders are not subscribable either. namespace public { separator = . prefix = COMPANY. location = maildir:/home/services/mail/arinbe.com/arinbe/Maildir:CONTROL=%h/shared-set… hidden = no inbox = no } namespace public { separator = . prefix = ROOTMAIL. location = maildir:/home/services/mail/arinbe.com/rootmail/Maildir:CONTROL=%h/shared-s… hidden = no inbox = no } # default namespace namespace private { separator = . inbox = yes hidden = no prefix = INBOX. }

[Dovecot] FC4 and Dovecot 1.0 not displaying all migrated mailboxes
by Lovell Mcilwain 02 Nov '06

02 Nov '06

Hello all, I recently switched to dovecot on my FC4 server from UW-IMAP on my Mac OS X 10.3 machine and I was able to get my inbox and my trash box to be seen without any issues but all of my other mailboxes don't seem to show up. My mail directory is ~/mail and that is where I placed all of my mailboxes that I moved from my mac, but when I log into my new server using SSL/IMAP, only my trash and my inbox show up. My other mailboxes don't show up at all. Can anyone tell me how I can get my other mailboxes to show? As far as I know these mailboxes are standard unix mailbox files. Thanks

[Dovecot] BUG in RC10 deliver using mbox format
by Steven F Siirila 02 Nov '06

02 Nov '06

After recently adding the -f parameter to the call to the deliver command which is called by Postfix, I found that e-mail with a null return path (MAIL FROM:<>) was causing Dovecot deliver to SEGFAULT. I verified this by making this patch to deliver.c (notice I fixed a typo here, too): *** deliver.c.orig Fri Oct 13 07:32:28 2006 --- deliver.c Fri Oct 27 21:26:08 2006 *************** *** 446,454 **** i++; if (i == argc) { i_fatal_status(EX_USAGE, ! "Missing envleope argument"); } ! envelope_sender = argv[i]; } else { print_help(); i_fatal_status(EX_USAGE, --- 446,455 ---- i++; if (i == argc) { i_fatal_status(EX_USAGE, ! "Missing envelope argument"); } ! if (*argv[i]) ! envelope_sender = argv[i]; } else { print_help(); i_fatal_status(EX_USAGE, While this fixed my SEGFAULT, it still leaves the "From_" line with the default "dovecot.deliver" as the return path, something I don't want. It should be "MAILER-DAEMON" or some-such just like all the other LDAs in the case of a NULL return path. Perhaps there needs to be a new parameter so one can specify what a NULL return path should be converted to when it is encountered... Also, note that the "Usage" message in deliver.c does not include the relatively new -f option either, so that should have been part of my above patch as well. -- Steven F.

[Dovecot] quota with sendmail and dovecot
by Antonio Casado Rodríguez 02 Nov '06

02 Nov '06

I have a problem with dovecot and quotas I don't want quota in INBOX with sendmail (mbox), it's work ok. Sendmail can put the new messages in INBOX although exceed the quota limit. I have two namespace in dovecot: namespace private { separator = / inbox = yes prefix = "#mbox/" location = mbox:/Public/Maildir/%n_mbox_indexes:INBOX=/var/mail/%n } namespace private { separator = / prefix = "" location = maildir:/Public/Maildir/%n } I have this quota: plugin { quota = maildir:storage=10240 } It's work ok, i have 10 MB in INBOX and i have 10 MB in maildir. My clients are Mozilla Thunderbird My problem: when Sendmail put one new message in INBOX, Thunderbird see it, but the quota don't change. I think that when dovecot do a full sync it must update the quota.

[Dovecot] mbox_sync_read_and_move failure
by Timothy Daly 02 Nov '06

02 Nov '06

Hi, I recently switched to using dovecot for my IMAP server. I'm running dovecot 1.0rc10 on redhat linux 7.3. The filesystem is ext2, not NFS. I'm using mbox for mail storage. It worked okay for a day or two, but now when I try to check my mail I get an error from evolution, my imap client, saying that the server unexpectedly disconnected. In the server logs I see: Nov 2 13:10:49 tenkan dovecot: imap-login: Login: user=<tim>, method=PLAIN, rip=192.132.92.15, lip=216.114.78.229, TLS Nov 2 13:10:58 tenkan dovecot: IMAP(tim): file mbox-sync-rewrite.c: line 405 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) Nov 2 13:10:58 tenkan dovecot: child 30315 (imap) killed with signal 6 I see that this came up on this list a little while ago, but it doesn't sound like it got resolved. For the moment, I'm unable to read my mail via IMAP. :/ Any ideas?

[Dovecot] Dovecot-auth stand alone
by Jorgen Lundman 02 Nov '06

02 Nov '06

Since you have to have a SASL implementation with Postfix, either Cyrus or Dovecot, would it be feasable to have autoconf options to build only those parts required? Currently I attempt to disable most things, except for LDAP which we want to use: ./configure --with-ldap --without-pop3d --without-passwd --without-passwd-file --without-shadow --without-pam --without-checkpassword --without-bsdauth --without-vpopmail --without-ssl --without-deliver --without-sql-drivers --with-storages= That still compiles, and installs, imap. No way to stop that. However, master process "dovecot" does not want to start with "protocols=" set to empty. This is somewhat understandable, but I really do not want any listening ports, just the Unix auth socket and dovecot-auth process. Bind localhost for now? I take it I should run dovecot-auth as stand-alone, setting the AUTH_1 environment variable as well as a few others.

[Dovecot] 1.0.rc10 status report
by David Lee 02 Nov '06

02 Nov '06

(Background: Relatively new to dovecot; looking to do transparent replacement of long-established UW-IMAP on cluster of Linux boxes which NFS-mount a shared "/var/spool/mail".) With rc8, where I had already increased "login_max_processes_count" from default 128 to 1024, we had still hit the issue of too many logins crashing dovecot, so that trial had only lasted a couple of hours. With rc10, I doubled this to try to avoid the problem (I didn't want to risk testing the new code that addressed the problem... sorry!). We ran for almost a full working day. Good! Because of a few issues (below) I then backed off. 1. "User unknown": We use NIS for our passwd information. On the earlier rc8 test we had had several occurences of "User unknown" (from "deliver") giving "dsn=5..." for perfectly valid users. So for this rc10 test I applied a local patch so these were reduced to "EX_TEMPFAIL" (dsn=4...). (This was triggered, as epected, a few times and subsequent delivery attemtps succeeded.) I strongly suspect that this is some sort of issue with FC5, probably "nscd" and nothing to do with dovecot. Hints would be nice, but from the dovecot perspective you may probably ignore this item. 2. For one particular user, the "deliver" consistently gave: Failed to create storage for '...' with mail 'mbox:/HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB:INBOX=... I think this is ultimately due to something strange in the user ".forward" file. I'd be delighted to follow this up with anyone else who might have seen it. Although in one sense we may be drifting off-topic, in another sense I suspect that there is scope for adjusting "deliver" to handle this more gracefully. 3. There were several occurences of: IMAP(...): file ../../../../../src/lib-storage/index/mbox/mbox-sync-rewrite.c: line 405 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) child 30842 (imap) killed with signal 6 This looks particularly awkward. Any thoughts? 4. There were two occurences of: IMAP(...): file ../../../src/lib-index/mail-index.c: line 1801 (mail_index_move_to_memory): assertion failed: (index->fd == -1) child 20493 (imap) killed with signal 6 Again, this looks particularly awkward. Any thoughts? For these last two items, note that the indexes are currently NFS-shared alongside the INBOX area. I'm still not clear on how to regard the concept of indexes, as applied to a small cluster of machines, and handling simultaneous updates to INBOXes (analogous to the vital importance of INBOX locking for such updates). If one imagines the IMAP daemon (and pop and deliver) as file-clients of the (NFS-shared) INBOXes on a fileserver, do the indexes belong very close to the INBOXes (fileserver) or the dovecot software (file client)? So should I have the indexes on the fileserver (one instance), or should they be on each cluster machine's private storage (possibly several instances; one per cluster machine)? I've got them on the server; would they be better on the cluster clients? (Might that be the cause and fix of these two problems?) -- : David Lee I.T.

[Dovecot] valid_chroot_dirs question
by Luca Corti 02 Nov '06

02 Nov '06

Hello, I've got a dovecot setup using PAM and real system users. In this setup I also use pure-ftpd to give local users ftp access to their $HOMEs. To have pure-ftpd chroot into the user home i replaced /home/user with /home/user/./ in /etc/passwd. Unfortunately this breaks Dovecot this way: Oct 23 18:18:20 localhost dovecot: Invalid chroot directory '/home/foo' (user foo) (see valid_chroot_dirs in config file) and dovecot.conf says # ':' separated list of directories under which chrooting is allowed for mail # processes (ie. /var/mail will allow chrooting to /var/mail/foo/bar too). # This setting doesn't affect login_chroot or auth_chroot variables. # WARNING: Never add directories here which local users can modify, that # may lead to root exploit. Usually this should be done only if you don't # allow shell access for users. See doc/configuration.txt for more information. #valid_chroot_dirs = Now if I set valid_chroot_dirs = /home everything works, but the WARNING pretty much scares me since user foo HAS shell access. Is this safe? Is there a way to avoid this? Why I can't chroot to /home/foo/./ if I can to /home/foo ? I'm on 1.0rc10 thanks

[Dovecot] Installation of Dovecot
by Steven F Siirila 02 Nov '06

02 Nov '06

When I configure Dovecot to conform to our directory hierarchy, it insists on adding 'dovecot/' to the prefixes I specify. Is there any way to inhibit this? My configure command is: ./configure --prefix=/opt/dovecot --sysconfdir=/etc/opt/dovecot \ --libexecdir=/opt/dovecot/libexec --localstatedir=/var/opt/dovecot \ --without-sql-drivers --with-ssl=openssl \ --with-ssldir=/etc/opt/dovecot My problem is with the resulting directories: /opt/dovecot/libexec/dovecot is used instead of /opt/dovecot/libexec /var/opt/dovecot/lib/dovecot is used instead of /var/opt/dovecot/lib /var/opt/dovecot/run/dovecot is used instead of /var/opt/dovecot/run It seems that Dovecot assumes that libexecdir and localstatedir refer to non-Dovecot-specific directories, and adds 'dovecot/' to the path. Is there any way to avoid this? In our environment )we use: /opt/XXX Optional software XXX /etc/opt/XXX Configuration for optional software XXX /var/opt/XXX Variable data for optional software XXX (Which makes for easier upgrades) -- Steven F.

[Dovecot] imap process crashing with "file mail-cache-fields.c: line 26: unreached"
by JB Zimmerman 02 Nov '06

02 Nov '06

Hoping someone's seen this and/or can help...heh. I'm running the at rpm of dovecot, version dovecot-1.0-0_27.rc10.el4.at. I'm running it on RHEL4, up to date. We're using Maildir (we're upgraded from a Courier-IMAP installation) and things are working...but...we have a few users with very large mailboxes (not their inboxes) where they archive stuff (200k+ messages). When they try to read those mailboxes, the imap server instantly drops the connection, and I get the following in the log: --cut-- Oct 27 11:20:11 hostname dovecot: IMAP(user): file mail-cache-fields.c: line 26: unreached Oct 27 11:20:11 hostname dovecot: child 27514 (imap) killed with signal 6 --cut-- host and user names changed to protect the guilty. I have tried increasing the imap process size max to 512, as well as doubling the IMAP command size to 131072 (bytes)? Neither made a difference. *other* mailboxes on the same account work fine. The error happens *immediately*, not after a timeout, as soon as they select the mailbox in their client (we're using Evolution, and have tried pine as well...I'm working on trying other clients). The Maildir caching optimization settings in the conf are left to default. Any ideas? Many thanks. J.B. Zimmerman --

Re: [Dovecot] Clustering (replication and proxying) plans for the future

The reply will then take the highest > priority in the queue. Is your primary goal with this replication to add redundancy or to distribute load such as for shared mailboxes? I've thought about the redundancy side of this a lot, but not so much about load distribution. It sounds like you're going for load distribution, but... If the goal is redundancy, I'd suggest that mailbox state is less important than the mail data. Index files can be recreated from the data, and would not even be needed on the secondary server(s) unless the primary fails. So I'd put a higher priority on getting the mail content to the secondary servers. If the goal is to distribute load for shared mailboxes, then your prioritization makes sense. Also, if the goal is redundancy, this design can be simplified a lot by having one master and one or more slaves. All modify operations would go to the master, so that you do not need global locks. Different sets of users would belong to different namespaces, so that you can have multiple replication paths in your cluster. You'd also want an API for the replication process so that third-party applications that modify mailboxes can log those changes so that they are replicated. And in that case, the replication process could be made generic enough so that it can be used to replicate any set of files, with or without Dovecot. Bill

[Dovecot] CRASH: mail-cache-fields.c crash - new info, hacked 'solution'
by JB Zimmerman 01 Nov '06

01 Nov '06

I'm baaaaack. :-) I've managed to implement a suggestion from Hans Morten Kind from this list that seems to have stopped the crashing. However, my hack - commenting out a call to i_unreached() - makes me queasy because I have no idea of the ramifications of it (I don't habitually code, myself). So I wanted to lay it out for y'all in case this is a problem that you feel should be looked at. So, here's my situation. Using dovecot-1.0.rc10 downloaded from dovecot.org. Built an RPM locally on my machine (as opposed to prior attempts, which used the AT rpms), which is running RHEL 4AS with all updates. Did *not* configure in postgres, mysql, sqlite, ldap-auth. Other than that, stock (openssl included, eg) - some file locations taken from AT RPMs' spec (redhat specific file locs). No patches performed. SPEC available if y'all think it'd help; the RPM built with no complaints, installed same. Using Maildir format, upgraded from a Courier install, so .folder.subfolder structure. Error behavior: When a user attempted to open a folder containing large numbers of messages (roughly 100k+ messages, as far as we can tell) they immediately got an error saying the server has disconnected. On the server side, I got this in the log (hostname 'magneto' obviously) ---cut--- Nov 1 15:18:16 magneto dovecot: IMAP(joeuser): file mail-cache-fields.c: line 26: unreached Nov 1 15:18:16 magneto dovecot: child 17599 (imap) killed with signal 6 ---cut--- Now, the folder in question is a folder of CVS commit messages (hence the size). If I go into the folder ("/home/joeuser/Maildir/.GNOME CVS commits/") and do 'rm -f dovecot-*' and then have the user try again, then they can open the folder and get a message list. dovecot will rebuild the various index files. However, as soon as they click on an individual message, bam, the same error behavior - and from then on, they can't get into the folder again unless we remove their dovecot files again. We tried this using Evolution, mutt and pine as the clients. All exhibited identical behavior. This is coming over TLS. NOW THE FIX: I made a change to the source (gasp!) that honestly I have no idea the ramifications of, but it has...well, not *fixed*, but sorta fixed it. As per Hans Morten Kind, I commented out the i_unreached() call in field_has_fixed_size(). After this, the mail is readable as is the folder list, but now there is an error message in the log. First things first, here's the change I made to dovecot-1.0.rc10/src/lib-index/mail-cache-fields.c: ---cut--- @@ -23,7 +23,7 @@ return FALSE; } - i_unreached(); +/* i_unreached(); */ return FALSE; } ---cut--- ...and here's what now happens in the log, to the same mail folder as above: ---cut--- Nov 1 15:59:42 magneto dovecot: IMAP(joeuser): Corrupted index cache file /home/joeuser/Maildir/.GNOME CVS commits/dovecot.index.cache: field header names corrupted ---cut--- At that point, I deleted the cache files again, and the error goes away. I also notice that the index.cache file in that folder is much, much larger than it was, from which I posit that the above error was because the crashing imap process had left an incomplete index file. Removing it thus forced a rebuild with the new code which seems to have fixed the problem. Thank you all for your patience. I hand this willingly over to the list. jb -- ------------------------------------ J.B.

I have seen a few suggestions on how to address the issue of a system employing both real and virtual users and domains. Is there any definitive solution as to how this should be accomplished? The system I am construction will have several hundred users, both real and virtual, and probably seven domains.

[Dovecot] Upgrade from RC7 to RC10 didn't go too well...
by Dominic Lepiane 01 Nov '06

01 Nov '06

Hi, On the weekend I tried to upgrade from RC7 to RC10. Clearly, I have to change some things before I can do this. What does it take to get to RC10? As is, my mail client got an error trying to list messages in /INBOX (via IMAP) and the mail.err log shows the following messages: Oct 29 10:27:32 siona dovecot: IMAP(archangel): open(/var/mail/archangel/inbox, O_CREAT) failed: Not a directory Oct 29 10:27:32 siona dovecot: IMAP(archangel): mkdir_parents(/var/mail/archangel/.imap/INBOX) failed: Not a directory Oct 29 10:27:32 siona dovecot: IMAP(archangel): open() failed with subscription file /var/mail/archangel/.subscriptions: Not a directory My dovecot.conf includes default_mail_env = mbox:/var/mail/%u And other then enabling SSL, I've got a pretty vanilla configuration (e.g. nothing in the IMAP section at all, no odd namespaces...) /var/mail/archangel is an mbox file, why is dovecot trying to open files under there? I know at least part of the discussion has happened on the list before so I'm sorry for duplicating other questions. My TODO is about ten km long so I hope someone can at least give me a couple good pointers. Thanks in advance! -- Dominic Lepiane The IRMACS Centre

[Dovecot] moving public folders to private Trash
by Mark Nienberg 01 Nov '06

01 Nov '06

Using Thunderbird 1.5.0.4 against dovecot beta9: If a user has Thunderbird configured to move deleted messages into a Trash folder, then the user cannot delete folders in a public namespace. There is no problem deleting messages. Thunderbird says: "The current command did not succeed. The mail server responded: Can't rename mailbox to another storage type." All mailboxes (public and private) are maildir format. Users can successfully delete folders from their own private areas, and the folders then appear as subfolders of the Trash folder. Also, users can reconfigure Thunderbird to delete messages immediately instead of moving them to trash and then successfully remove public folders. Also, users can move public folders within the public namespace. So I think the problem boils down to the inability to move a folder from a public namespace to a private one, which is what happens when Thunderbird is configured to move deleted messages to a Trash folder.

[Dovecot] IMAP Dovecot with ISPConfig and shared folders?

Fedora 5, postfix, dovecot, ISPConfig server all running well, (don't want to break it) LOL. But, I do not have IMAP shared folders. These instructions on dovecot tell of how to setup namespace to be able to get shared folders. http://wiki.dovecot.org/SharedFolders But given everything is relative in ISPConfig, not sure if this is possible or if I could really mess things up. What tells dovecot to look in the various different web# folders for email? Am I better off using Symlinking???

[Dovecot] Problem report

Hello guys, Dovecot is a great IMAP server, I really like it :) I recently found an annoying problem, however: To sync my mail, I use OfflineIMAP, which usually works very smoothly. A spam mail with the year set to 2038 produced the error message "Invalid internal date" when OfflineIMAP tried to upload it to the server. Only deleting the messag helped. The usual data: Dovecot 0.99.14-1sarge0 on Debian Sarge x86. It would be nice to remove this date-smartness (?)...

[Dovecot] Continuing problems with zombied dovecot-auth procs; mail-cache-fields.c IMAP procs crashing
by JB Zimmerman 31 Oct '06

31 Oct '06

Folks- Hans Morten Kind was kind enough to confirm the issue I'm having with large mailboxes and the mail-cache-fields.c file (line 26: unreached error in logs when the imap process crashes out on large Maildirs). Has anyone implemented a fix for this that is both tested and applicable without making manual code changes myself, since I don't trust myself slashing about in source files? Ideally, has this problem been noted for fixing in a newer version? Failing that, if I downgrade to the 0.99 version shipped with RHEL4, has anyone found that to be more reliable? I used the 1.0rc10 in order to gain access to the 'namespace' conf directives so that upgrading from our current Courier Maildir installations would be as seamless as possible, but at the moment, I'm looking at having to roll back to Courier in order to fix this (and the next) problem. Also, we have found that using 1.0rc10 on RHEL4, using pam-ldap for account info and pam-krb for auth, has resulted in the eventual inaccessability of mail due to many zombied and unresponsive dovecot-auth processes. Restarting dovecot the first few times it becomes unresponsive will fix the problem, presumably by instantiating new auth procs, but eventually this no longer works since the restart doesn't actually kill off the zombied auth procs and the socket stops responding. Has anyone run into this problem? Thanks, J.B. Zimmerman RHEL4AS, fully updated, using the AT rpms: dovecot-1.0-0_27.rc10.el4.at --

[Dovecot] Multiple certificates
by Phill Edwards 31 Oct '06

31 Oct '06

I have dovecot version 1.0 relese 0.beta8.2.fc5 installed on my FC5 linux box. It acts as an IMAP server to my home LAN. I connect to it from the home PCs over SSL and have installed a certificate in the domain imap.edwards.home to enable this. However, I also use a web site called www.xs2mail.com which retrieves the email from my IMAP server (which has a public DNS entry called XXX.homelinux.com) and displays them in a web interface. I used to run uw-imap and this all worked fine. But since I went to Dovecot I can't use that site any more because it gives me this message: Login failure: Certificate failure for XXX.homelinux.com: self signed certificate: /C=AU/ST=NSW/L=Sydney/O=Edwards/OU=IMAP server/CN=imap.edwards.home/emailAddress=philledwards(a)gmail.com I assume it's getting upset because the certificate is for imap.edwards.home but the domain it's connecting to is XXX.homelinux.com. Is there a way to resolve this? I read something about using virtual servers but all I could find is this in a post somewhere - I don't know which file it goes, where in that file etc: <snip> 1.0-tests support "virtual servers", where this is possible: server foo { listen = 1.2.3.4 ssl_cert_file = /etc/ssl/certs/foo.cer } server bar { listen = 1.2.3.5 ssl_cert_file = /etc/ssl/certs/bar.cer } </snip> Can anyone help me figure this out? (PS - I can't just set up my own IMAP web interface because I can't run anything on port 80 with my ISP and I can't get out of our company firewall on anything other than port 80). Thanks in advance, Phill

I don't want to disable these mechanisms in auth {} stanza of dovecot.conf, because they are Ok over SSL/TLS. It works for dovecot-pop3 and dovecot-imap, but not for postfix :( postfix 2.3.3, dovecot 1.0rc10. -- Best regards, Lev mailto:lev@serebryakov.spb.ru

[Dovecot] LSUB and namespaces - how to get rid of multible prefixes
by Henrik Ostergaard Madsen 28 Oct '06

28 Oct '06

I'm using dovecot 1.0.rc7 and Squirrelmain 1.4.8 using IMAP on a Debian 3.1 Testing system, and I'm having a problem. When Squirrelmail (or other IMAP clients) submits an LSUB "" "*%", dovecot responds with: Request: A004 LSUB "" "*%" Response: * LSUB () "/" "INBOX.Sent" * LSUB () "/" "INBOX.Trash" * LSUB () "/" "INBOX.Drafts" * LSUB () "/" "mail/Sent" * LSUB () "/" "mail/Trash" * LSUB () "/" "mail/Drafts" * LSUB () "/" ".mail/Sent" * LSUB () "/" ".mail/Trash" * LSUB () "/" ".mail/Drafts" * LSUB () "/" "Sent" * LSUB () "/" "Trash" * LSUB () "/" "Drafts" * LSUB () "/" "INBOXSent" * LSUB () "/" "INBOXTrash" * LSUB () "/" "INBOXDrafts" * LSUB () "/" "./INBOX.Sent" * LSUB () "/" "./INBOX.Trash" * LSUB () "/" "./INBOX.Drafts" * LSUB () "/" "Test" Lsub completed. This is in spite of that only INBOX.Sent, INBOX.Trash, INBOX.Drafts and Test actually exists. I have tried with no explicit namespaces, only one with no prefix or with prefix "/", and with that again and all the above prefixes marked as hidden, but with absolutely no change in the LSUB repons. Due to this, Squirrelmail shows up a whole bunch of folders, but only the correct ones (without prefixes) works.. This has been the same with a few prior versions of dovecot 1.0 , but not with dovecot 0.99. It is the same for Squirrelmail 1.4.7, but I do not think the client matters.. Is there a setting or way to deal with this - or is it a bug? Regards, Henrik

[Dovecot] "dovecot dead but subsys locked" problem
by Carla Tironi Farinati 27 Oct '06

27 Oct '06

Hi, Following the advice of someone really helpfull here, I just installed Postfix/Dovecot (from rpms). I'm running CentOs 4.4. I followed this guide: http://www.howtoforge.com/linux_postfix_virtual_hosting I've got two problems, a)my server is now listed as RCB, whatever that means, I suppose that's close to spamming. "0: Connection refused. Your IP address is blocked(Spamhaus XBL) - see http://www.spamhaus.org/query/bl?ip=216.32.68.90 " b)[root@server ssl]# /etc/init.d/dovecot restart Stopping Dovecot Imap: [FAILED] Starting Dovecot Imap: [ OK ] [root@server ssl]# /etc/init.d/dovecot status dovecot dead but subsys locked I deleted the sybsys file and tried to restart it. It crashes and show the error agsin. The logs don't show up anything unusual. I also see in the logs: Oct 25 22:50:07 server postfix/virtual[24712]: 48BA5904990: to=<carlatf(a)ithaki.net>, relay=virtual, delay=1, status=deferred (mailbox /var/spool/vmail/ithaki.net/carlatf: cannot open file: Is a directory) Of course it's a directory!. I created it following the guide! I reinstalled Dovecot with the latest sources and nothing. I also turn off SSL from dovecot's config file, nothing. Any ideas dovecot gurus!? Best regards, Carla

[Dovecot] Clustering (replication and proxying) plans for the future
by Timo Sirainen 27 Oct '06

27 Oct '06

I wrote this mostly so that I won't forget my thoughts. Most likely won't be implemented anytime soon. I haven't thought through all the locking issues. It would require a distributed lock manager in any case. I think there are already several existing ones, so one of them could probably be used for Dovecot. Each mail server would consult a master server for getting namespace configuration and location for shared/public mailboxes. If the data is stored in some central SQL server there could just as well be multiple master servers (or even each server be their own master). Whenever trying to open a shared mailbox that doesn't exist in the current server, the imap process would automatically create a new connection for the destination server and start proxying the data. The proxy would be a somewhat dummy proxy, which just forwards the client's commands to it and doesn't even try to understand the replies from the remote server. So admin will have to be careful to use only servers which have all the capabilities that were announced by the original server. So, then the replication. Each namespace could be configured to be available either by proxying or by replication: namespace public { prefix = example/ location = proxy:imap.example.com } namespace public { prefix = example/ replicated_to = host1.example.com host2.example.com # If multi-master, we'll need to use global locking. If not, the # replicated_to servers contain only slaves. multi_master = yes location = maildir:~/Maildir } The way this would work is that each imap process connects via UNIX socket to a replication process, which gets input from all the imap processes. The replication process keeps track of how much has been sent to each other server and also the acks it has received from them. So if the network dies temporarily it'll start writing the changes to the disk until it reaches some limit, after which a complete resync will be necessary. Dovecot already writes all the changes to a mailbox first to a transaction log file and and only afterwards it updates the actual mailbox. The contents of the new mails aren't stored there though. The replication could work simply by sending the transaction logs' contents to the replicatio process which passes it onto other servers, which finally sync their local mailboxes based on that data. Since Dovecot already is able to sync mailboxes based on the transaction log's contents this should be pretty easy to implement. Of course the new mails' contents also have to be sent. This could be prioritized lower than the transaction traffic, so that each server always has very up-to-date view of the mailbox metadata, but not necessarily the contents of all the mails. If the server finds itself in a situation that it doesn't have some specific mail, it'll send a request to the replication process to fetch it ASAP from another server. The reply will then take the highest priority in the queue. Normally when opening or reading the mailbox there's really no need to do any global locking. The server will show the mailbox's state to be what it has last received from the replication process. Whenever modifying the mailbox a global lock is required. Here's also the problem that if the network is down between two servers, they both think that they got the global lock. If they did any conflicting changes, they'll have to be resolved when both of them again see each others. Dovecot's transactions in general aren't order-dependent so most of the conflicts can be resolved by just having the replication master decide which way the transactions were done and then sending the transactions back to all of the servers in that order. Adding new messages is a problem however. UIDs must be always growing and they must be unique. I think Cyrus solved this by having 64bit global UIDs which really uniquely identify the messages (ie. first 32bits contain server-specific UID), and then the 32bit IMAP UIDs. If there are any conflicts with the IMAP UIDs, they're given new UIDs (which invalidates clients' cache for those messages, but that can't be helped). Resyncing works basically by requesting a list of all the mailboxes, opening each one of them and requesting new transactions from the log files with <UID validity>, <log file sequence>, <log file offset> triplet. If UID validity has changed or log file no longer exists, a full resync needs to be done. Also if the log file contains a lot of changes, it's probably faster to do a full resync. Full resync would then be just sending the whole dovecot.index file. Conflict resolving could also require a full resync if transaction logs were lost. That'd work again by the master receiving everyone's dovecot.index files, deciding what to do with them and sending the modified version back to everyone. Each server has different transaction logs, so the log file sequences can't be directly used between servers. So the replication process probably will have to keep track of every server's log seq/offset. Also when receiving full dovecot.index files they'll have to be updated in some way. Then there's the problem of how to implement the receiving side. If the user already has a process connected to the replication process it could be instructed to update the mailboxes. But since this doesn't happen all that often, there also needs to be some replication-writer process which writes all the received transactions to the mailboxes. Now, when exactly should these replication-writer processes be created then? If all users have the same UNIX user ID, then there could be a spool of processes always running and doing the writing. Although this worries me a bit since the same process is handling different users' data. More secure way, and the only way if users have different UNIX UIDs, is to launch a separate writer process for each user. It probably isn't a great idea to do that immediately when receiving data for a user, but to queue data for the user for a while and then once enough has been received or some timeout has occurred, the writer process would be executed. There probably should be some shared in-memory cache with a memory limit of some megabytes, after which data is written to disk up to a configurable amount. Only after that is full or timeout for the user is reached, the writer process is executed and the data is sent to it. All this replication stuff could also be used to implement a remote mail storage (ie. smarter proxying). The received indexes/transactions could simply be kept in memory, and all the mails that aren't already cached in memory could just be requested from the master whenever needed. I'm not sure if there's much point in doing this over dummy proxying though.

[Dovecot] SpamAssassin training plugin
by Chad Parry 26 Oct '06

26 Oct '06

I found a plugin for dSPAM on this mailing list (http://thread.gmane.org/gmane.mail.imap.dovecot/4632/focus=4632) that was very useful to me. I just modified the code to work for SpamAssassin instead. The purpose of this plugin is to watch the mail that is in the user's spam folder. If the user manually moves a piece of mail into the spam folder then the mail must have been spam that was incorrectly classified. This plugin causes SpamAssassin to relearn that mail as spam. Anyone else who finds this functionality useful is welcome to follow the link below. . http://chad.parry.org/software/dovecot/ - Chad Parry

[Dovecot] mail_extra_groups and home directory permissions
by Joe Cooper 26 Oct '06

26 Oct '06

Hi all, I've got a virtual hosting environment, where each user lives in /home/domain/homes/user, and the mailbox is Maildir within that directory. I've been running into a permissions problem, because it seems Dovecot doesn't get the users group membership (which seems odd, but I'm not confident enough of my comprehension of Dovecot to call say it looks like a bug). In short, when Dovecot hits the /home/domain directory which is owned by domain:domain and set to 750 permissions, it gets a permission denied, despite the user having the needed group membership to traverse these directories. So, in an effort to work around this problem, I came upon the mail_extra_groups option, which seems to allow me to drop dovecot into additional groups. If I add the domain group to this list, dovecot is able to traverse to the correct directory and all works exactly as I want it to with the domain directories being set to 750 permissions. Hooray! My only question, since this is not the documented purpose of this option, is: Is it safe to do this? Am I opening up some other kind of security problem by setting this option to include all domain groups? Thanks for any thoughts anyone might have on this...

[Dovecot] "Real" users AND Virtual users
by Muhamad A. Martoprawiro 25 Oct '06

25 Oct '06

Dear all, How can I use dovecot for both "real" users and virtual users? I could configure dovecot for real users, by using these lines in /etc/dovecot.conf: default_mail_env = maildir:%h/Maildir auth default { passdb pam { } userdb passwd { } } To accept virtual users, I used these lines: default_mail_env = maildir:/usr/local/virtual/%u/ auth default { passdb sql { args = /etc/dovecot-mysql.conf } userdb sql { args = /etc/dovecot-mysql.conf } } But, again, how to accept both kind of users? I use Postfix as mail server, and use LDAP/PAM for real users that have home-directory on the system. My OS is Mandriva 2007, and I use dovecot that is bundled as an RPM package (dovecot 1.9 rc7) in the OS. The content of file /etc/pam.d/dovecot: #%PAM-1.0 auth required pam_stack.so service=system-auth account required pam_stack.so service=system-auth Thanks. Regards, Muhamad

[Dovecot] performance problems with rc10 and solaris 10

25 Oct '06

Hi, i have 2 dovecot imap server running on solaris 10 The primary server with dovecot 1.0.alpha4 is running with best performance on Sun Sparc E4k5 with 8x 450MHz The secondary with rc10 has ugly performanceproblems on Sun E450 wth 4x 450MHz. Every new imap process takes permanent 25% cpu usage List the folder and fetch message are both slowy! Both servers are configred with ldap backend preventive i deleted for rc10 the complet index and controlfiles, because the spooldir is a sync from the masterserver with dovecot alpha4. I thought its a little bit slowy because of my 30.000 mails. the indexfiles are created now, but the still ugly slow .... For debugging i compiled rc10 again --with-debug=yes and start dovecot with solaris truss truss tells nothing to explain this behavor logentrys from dovecot has this warnings: --> dovecot: Oct 18 14:51:47 Warning: IMAP(saar): Growing pool 'storage' with: 1024 dovecot: Oct 18 14:51:47 Info: IMAP(saar): dirsize quota limit = 750000kB dovecot: Oct 18 14:51:47 Warning: IMAP(saar): Growing data stack with: 32768 dovecot: Oct 18 14:51:47 Warning: IMAP(saar): Growing data stack with: 65536 dovecot: Oct 18 14:51:48 Warning: IMAP(saar): Growing data stack with: 131072 dovecot: Oct 18 14:51:48 Warning: IMAP(saar): Growing pool 'uidlist record_pool' with: 32768 <-- also i compiled rc10 --with-notify=none, no result to ensure it isn´t the solaris system, i compiled alpha4.

[Dovecot] Unsolved : mbox-sync-rewrite.c : assertion failed
by Jakob Curdes 25 Oct '06

25 Oct '06

Some days ago I wrote about an inaccessible mailbox after an upgrade from 0.99.14 to 1.0rc10. Today I get this problem with another mailbox but it seems to be it is not only related to the upgrade : - user comes back from holiday, does not see his inbox : dovecot: Oct 24 18:51:09 Error: IMAP(abcd): file mbox-sync-rewrite.c: line 405 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) (he accessed it last with the old dc version) Solution : moving account to other server, copy everything over to the old account and it worked. This is what I did and afterwards the mailbox was readable. Now the user goes back to his PC (I made my work from another machine) and opens his mailclient (with the still existing account) and BINGO dovecot crashes again on the mailbox as berfore. Once ist has crashed on it, it than crashes always, even if you make a new account or remove the index. So I suppose it has rather to do with cached information in the client than with the upgrade itself. But nothing the client sends should be able to crash the server ! Hoping for an idea, Jakob Curdes

[Dovecot] Status of Shared Folders?
by Charles Marcus 24 Oct '06

24 Oct '06

Hi Timo, I'm just curious... is the Wiki up to date regarding the status of Shared Folder support for Dovecot? Specifically, does Dovecot still have a problem with Read-only (for certain users) maildirs using Shared folders defined via namespaces? I'm about ready to start testing a rollout, but wanted to find out what to expect with regard to Shared Folders - we use them extensively right now (Courier-imap), so it is important for us. Having per-user read/unread flags will be a very nice bonus, but I don't see anything about support for those... -- Best regards, Charles Marcus I.T.

[Dovecot] converting from courier questions
by Aaron P. Martinez 24 Oct '06

24 Oct '06

I currently run postfix and courier on my mail servers with squirrelmail. The problem with courier is it seems to run so slow. The webmail takes forever to load if you have many mails. I have this set up in virtual domains with all longin and path info in an mysql database. I just joined the list and DID google before asking, hope this isn't a common question. With courier it looks for a "homedir" and then a "maildir".. I tried doing a query as such: user_query = SELECT Homedir and Maildir AS home, VUID AS uid , VGID AS gid FROM users WHERE Email_address = '%u' to no avail, is my sql wrong or can you not cat the homedir and maildir fields together to create the complete path to home? . i got around the homedir problem by setting mail_chroot = /var/spool/postfix/virtuals (is this the general way, only way?) and then in my dovecot-mysql.conf i have user_query = SELECT Maildir AS home, VUID AS uid , VGID AS gid FROM users WHERE Email_address = '%u' This almost worked but as i was watching the logs it was looking for /var/spool/postfix/virtuals/<somedomainname>/Maildir//Maildir In courier the "Maildir" is not implied, it has to be spicified in the database. I have a LOT of users and would love to avoid chaning every line in my database. or add another filed just for dovecot. I would also like the ability to switch back and forth for testing with courier.. Is there anyway that this can be done? Thanks in advance, Aaron

The problem appears only when the ldap connection breaks (e.g. remote ldap server restart). We don't use rootbinddn at all. Anyway I just checked the latest version of nss_ldap and now I see interesting new relevant options are available (e.g. nss_connect_policy persist/oneshot). I will give it a try and respond back in a few days. Definately nss_ldap's bad behaviour is not really a dovecot problem.

I was using dovecot ->getpwent -> nscd -> nss_ldap -> LDAP. I found out that whenever the ldap server got restarted, nscd did not restart properly and immediately its permanent ldap connection, and was giving 'user unknown' replies at least for a few minutes. Restarting nscd would fix the problem immediately. Running without nscd would also fix the problem. There was no problem with pam_ldap authentication. As a result, the system got ignorant of its uncached users for a few moments. My workaround was a crontab that kept /etc/passwd up-to-date as well as an entry in the /etc/resolv.conf 'passwd: ldap files' (cat /etc/passwd ; getent passwd ) |sort -u >/etc/passwd.tmp && mv /etc/passwd.tmp /etc/passwd > So should I have the indexes on the fileserver (one instance), or should they > be on each cluster machine's private storage (possibly several instances; > one per cluster machine)? The suggestion is that if you need to have mailboxes over NFS, use local disk for indexes. If you read the complete list archive you will find too many people that have had troubles with indexes over NFS. Local indexes have a performance penalty, only when you have access from different imap servers (especially concurrent) . apap

[Dovecot] mysql-5.0.26 stored procedure authorization, take 2
by Chaos Engine 22 Oct '06

Last time I came up with a problem with concernin MySQL authorization with stored procedures. Timo helped me get going by with modified client_flags (MULTISTATEMENT keyword). Now all it happened again but from another way. My stored proce for MySQL is causing fillowing error: "Oct 21 12:39:22 haos dovecot: auth-worker(default): sql(user,192.168.X.X): Password query fai led: Commands out of sync; you can't run this command now" Looks like it is partly mysql-5.0.26 thing because of this: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html On the other hand with my previous mysql installation (mysql-5.0.24-r1) this error is gone (I checked by downgrading). My dovecot-sql.conf: driver = mysql connect = host=/var/run/mysqld/mysqld.sock dbname=mailbase user=mailuser password=******** client_flags=65536 #655536 is equivalent of CLIENT_MULTI_STATEMENTS flag #yes, I still insist on using stored proc for authorization. This gives me few usefull features I like. password_query = call Authenticat('%u', '%n', '%d') With this config on mysq-5.0.26 I get "...Commands out of sync; you can't run this command now..." but not on mysql-5.0.24-r1. Personally I think mysql guys changed something; I can't tell what and why (changelog review?) Maybe you guys know what it was? -- Chaos greets U

[Dovecot] Using saslauthd with dovecot
by Gerard Seibert 21 Oct '06

21 Oct '06

FreeBSD 6.1 STABLE Postfix-2.4-20061006 Dovecot-1.0.rc7 I am using 'saslauthd -a sasldb -c' for authentication with Postfix. Since Dovecot and Postfix are using the same users and passwords, I was wondering if it would be possible to use this mechanism with Dovecot also. -- Gerard "There is nothing wrong with making love with the light on.
