Re: [Dovecot] Converting huge mbox to Dovecot mbox + indexes
by Bertrand Leboeuf 17 Mar '06

My mistake, good point. I thought that creating the indexes would take a long time, but after a couple of tests, I found that Dovecot is so fast that it beats UW IMAP even while creating the indexes and after that, it is just fast.

[Dovecot] mbox to maildir: what about INBOX
by Bertrand Leboeuf 17 Mar '06

17 Mar '06

I migrated from UW IMAP/Qpopper to Dovecot using: # indexes on /var/indexes is faster: local, not NFS mouted default_mail_env = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/var/indexes/%u # Qpopper pop3_reuse_xuidl = yes The new mail is sent to in /var/mail/%u in mbox format How can I migrate some users to maildir and have them receive their emails either in POP3 or IMAP. (lots of big files to convert) How does new email get spooled in the right INBOX (POP3/IMAP) ? Thanks. Bertrand Leboeuf leboeuf(a)emt.inrs.ca

[Dovecot] LDA Sieve debugging
by Luca Corti 17 Mar '06

17 Mar '06

Hello all, I've installed and setup the LDA with postfix. I'm trying out Sieve support, and wrote the following global script: require "fileinto"; if address :contains "To" "luca(a)mydomain.tld" { fileinto "Spam"; } and tried to send an email to that address. The sieve script seems to be processed and sieve-global.scriptc is compiled, but the message is not filed in the correct folder. Is there a way to debug the script execution? thanks -- Luca Corti PGP Key ID 1F38C091 BOFH excuse of the moment: Internet exceeded Luser level, please wait until a luser logs off before attempting to log back on.

[Dovecot] PAM authentification problem
by Vladislav Kyjasko 17 Mar '06

17 Mar '06

Hi everybody, we try to migrate our IMAP service from uw-imap to dovecot because of horrible server slowdown when a lot of people poking in theirs huge imap folders. So, I try to run testing instance of dovecot on different imap port (12143) I have trouble with authentication by PAM module of MIT Kerberos. It successfuly works for authentificate users of wu-imap but not for dovecot. I see in dovecot.log messages like that : Info: Dovecot v1.0.beta3 starting up Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip=10.0.0.154 rip=10.0.0.148 Info: auth(default): client out: CONT 1 Info: auth(default): client in: CONT 1 AGtDNLamUjvADNLamUjQRsbw== Error: auth(default): pam(kyyashko,10.0.0.148): Child process died Info: auth(default): shadow(kyyashko,10.0.0.148): invalid password field Error: auth(default): PAM: Child 6748 died with signal 11 Info: auth(default): client out: FAIL 1 user=kyyashko temp Almost all users are in kerberos DB and has in local shadow field "*KRB*" instead of encrypted password. So, line "shadow ... invalid password field" is OK (when I made a local password in shadow the login was success) My dovecot.conf looks like: sl_disable = yes protocol imap { listen = *:12143 } auth_default_realm = FZU.CZ auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } original /etc/pam.d/dovecot I introdused by lines auth sufficient pam_krb5.so auth required pam_unix2.so use_first_pass nullok or tryed to substitute whole file pam.d/dovecot by actualy working one of imap: #%PAM-1.0 auth sufficient pam_krb5.so auth required pam_unix2.so use_first_pass nullok auth required pam_unix2.so account required pam_unix2.so but similary fruitless. Which direction I have to dig? P.S. Dovecot was built from dovecot-1.0.beta3-6.src.rpm on SuSE 9.0 with the same result like from dovecot-1.0.beta3.tar.bz2 :(

[Dovecot] Install/configure on FC4 with maildir and mysql
by Netlink Tech 17 Mar '06

17 Mar '06

Hello, I have a FC4 x64 server that I am configuring/testing. It had dovecot 0.99 loaded after I did a yum update. That worked great with mbox, the passwd file, and test users in /home/users/username. I would like to be able to authenticate virtual users by 'username(a)domain.com' and have them be able to use squirrelmail or Outlook/Outlook Express to access their email. Users have no reason to have a login (shell) account on this machine. I also would like to use the maildir format for performance. I also have hundreds of users currently on a RH9 mail server using qpopper in mbox format, hashed mail spool. Questions: 1)Is a mysql database the best way to support "user(a)domain.com" email users? (they don't have any reason for a shell account on this machine) 2)What version of dovecot should I be using? I prefer RPMs and at http://www.dovecot.org/list/dovecot/2006-February/011467.html I found http://fedora.ivazquez.net/yum/4/x86_64/RPMS.alternatives/dovecot-1.0-0.iva… I installed this and then configured procmail for maildir delivery. I configured dovecot-sql.conf for mysql driver...but the mysql driver does not appear to be compiled in this rpm. 3)Anyone have any general tips on how to configure such a beast? Thanks, Curt

Hello All. I've been reading the virtual user howto but cant get the login working. dovecot.conf is below [0] if anyone can offer some pointers. I'm confused about the format of /etc/imap.passwd [1] also. Does the "pass" word in the example need to be plaintext, or the MD5 string from do. Also, what is the significance of "{plain}"? If there are docs I've missed, please RTFM with a link.

It's my server and it's still running and working properly. Dovecot version is (as on the newer server) beta3, but the first Dovecot running was beta2 I think. Imap works properly on that server. Anyway Dovecot shouldn't crash ever if the index files are broken!

[Dovecot] Shared Folders Problem. Bug?
by Adam M. Dunn 16 Mar '06

16 Mar '06

I'm trying to get shared folders to work, and I've noticed a few issues. I created a private and public namespace, the private one with autodetection for Maildir or Mbox, and the public one for a public folder. Something like this: namespace private { separator = / inbox = yes prefix = location = } namespace public { separator = / prefix = Public/ location = maildir:/var/mail/public } My plan is to eventually setup a public area for users to drop Spam and Ham into for my spam bayesan filter. The problem is the Wiki says if you drop a file in the public area called 'dovecot-shared' with the same permissions and ownership, that any new files dovecot creates there will use those same attributes. This does not seem to be the case. I created a Maildir folder identical to the one on the Wiki, named everything 'dovecot:dovecot' since my dovecot server will be running as that user, as well as the 'dovecot-shared' file. I get permission denied errors in syslog when I try to access it via an IMAP client. The only way I can make it work is ignore the dovecot-share file and put all users in a common unix group and make the Public folder group 'rwx'. Also, I would like to be able to make the Public folder writable, but not readable. It seems if I take the read bit away, my IMAP clients complain. Does anyone know how to make that work? One thing about the namespaces while I'm at it. I had to put my private namespace first followed by the public one. If I reversed them, all the subfolders except the inbox in my mail directories disappear from the client. Is that a bug too? Thanks, Adam

[Dovecot] Problems with Oulook Clients
by Patrick Carney 16 Mar '06

16 Mar '06

Hello all. I have problems with clients running Outlook 2003 that keep getting IMAP server timeout errors, "mailbox in an inconsistant state" Are there any mods to be made to the config file that could eliminate this? It happens about ever 10minutes. Here is what our previous Sys Admin sent me on our setup. dovecot is the IMAP server that allows clients to connect and get to their mailboxes. Postfix is that part of the mail system that moves messages around, from one server to another and puts them in the appropriate mailboxes. Thanks Patrick

[Dovecot] Imap crashes when trying to move messages

The imap process crashes when SquirrelMail wants to move a message to another folder. I have run imap in gdb and talked to it the same way SquirrelMail does and got a backtrace.

[Dovecot] Strange dovecot-uidlist behavior on maildir conversion
by allen petersen 15 Mar '06

15 Mar '06

Hi. So I just moved my email over from mbox to maildir. For the most part the conversion went fine, but I had a bit of an odd thing happen when I accessed my mail through dovecot. It seems that when I ran mb2md to convert my mailboxes from mbox to maildir, I got a lot of messages created that look like 1142356176.000000.mbox:2,RS 1142356176.000421.mbox:2,S 1142356176.000001.mbox:2,S 1142356176.000422.mbox:2,RS 1142356176.000002.mbox:2,RS 1142356176.000423.mbox:2,S 1142356176.000003.mbox:2,RS 1142356176.000424.mbox:2,S and so forth. Now, that really should be fine, that I can tell; each message has the same timestamp and a different, sequential delivery identifier. However, for some reason when dovecot accessed this directory, it created UIDs for these messages like so: (from dovecot-uidlist) 1 1142362834 915 1 1142356176.000488.mbox 2 1142356176.000207.mbox 3 1142356176.000425.mbox 4 1142356176.000117.mbox 5 1142356176.000398.mbox 6 1142356176.000335.mbox I have no idea where this order came from, but it's clearly not the order that I would have expected. I would expect that dovecot would sort these messages by timestamp, followed by delivery identifier. Instead, it put them in a seemingly random order. And, of course, my email client by default shows messages in the order that it gets them from the server, so now when I look at my email all of my old messages are shuffled until I do an explicit sort by date. Any idea why this is happening? Is there some reasoning behind this, or is it just a bug? I looked through the archives a bit, but didn't find a mention of anyone else with this particular problem. I suppose I could just create the initial uid lists by hand and put them in the correct order, but that really doesn't seem like the correct solution. Or I could actually dig through the source and find out exactly what it's doing, but, well, I figure that asking the list first is easier. For reference, I'm running dovecot 0.99.14-1 on debian sarge. I though that I was doing a good job by reproducing this on the newer version my ubuntu desktop, but it turns out that it's running the same version. :) -allen

[Dovecot] Rootless configuration
by James Davis 14 Mar '06

14 Mar '06

I'm trying to setup a rootless configuration so I can better manage the e-mail that comes to the mailbox of a unix account I have. I've successfully compiled Dovecot and followed the instructions for a rootless configuration, tweaking my config until Dovecot returns no errors. However I've got to a stage where upon running ~/..../sbin/dovecot it just quits with no server running and no errors. Any ideas? My rather small and basic configuration file is as follows... # Base directory where to store runtime data. base_dir = /home/jamesd/imap/dovecot/run/ # Protocols we want to be serving: protocols = imap listen = * ssl_disable = yes log_path = /home/jamesd/imap/dovecot/logs/ info_log_path = /home/jamesd/imap/dovecot/logs/ ## Login processes login_dir = /home/jamesd/imap/dovecot/run/login login_chroot = no login_user = jamesd ## IMAP specific settings protocol imap { listen = *:10143 } ## Authentication processes auth default { mechanisms = plain passdb passwd-file { args = /home/jamesd/imap/dovecot/etc/passwd } user = jamesd } Many thanks, James -- http://www.freecharity.org.uk/ - Free hosting for charities http://jamesd.ukgeeks.co.uk/

[Dovecot] Shared maildir through namespace help...
by Brice Figureau 14 Mar '06

14 Mar '06

Hi, I'm a happy user of dovecot since the 0.99.x days, and recently switched my user base to 1.0b2. Now, to the point, I got a request (from marketing) to share a lot of maildirs between two (and possibly more) accounts. Those two accounts have differents uid/gid. The maildirs are actually in one of the account. I thought I could possibly craft a public namespace for those maildirs as explained in the wiki, but alas, it doesn't quite work as I expected: excerpt of dovecot.conf: namespace public { separator = / prefix = marketing/ location = maildir:/home/marketing/Maildir:INDEX=%h/ } users belong to the marketing group. $ find /home/marketing/Maildir -ls 4767751 4 drwxrwxr-x 3 marketing marketing 4096 Mar 14 11:57 . 4767752 4 drwxrwsr-x 6 marketing marketing 4096 Mar 14 11:59 ./Maildir 4767753 4 drwxrwsr-x 2 marketing marketing 4096 Mar 14 11:57 ./Maildir/cur 4767754 4 drwxrwsr-x 2 marketing marketing 4096 Mar 14 11:57 ./Maildir/tmp 4767755 4 drwxrwsr-x 2 marketing marketing 4096 Mar 14 11:57 ./Maildir/new 4767756 0 -rw-r--r-- 1 marketing marketing 0 Mar 14 11:57 ./Maildir/dovecot-shared >From there, the namespace is visible from all the IMAP accounts. Now, if a user creates a new folder in this public namespace, here is what I get: 4767757 4 drwx--S--- 5 brice marketing 4096 Mar 14 12:05 ./Maildir/.test 4767758 4 drwx--S--- 2 brice marketing 4096 Mar 14 11:59 ./Maildir/.test/cur 4767759 4 drwx--S--- 2 brice marketing 4096 Mar 14 11:59 ./Maildir/.test/new 4767760 4 drwx--S--- 2 brice marketing 4096 Mar 14 11:59 ./Maildir/.test/tmp 4767761 0 -rw-r--r-- 1 brice marketing 0 Mar 14 11:59 ./Maildir/.test/dovecot-shared 4767762 4 -rw------- 1 brice marketing 6 Mar 14 11:59 ./Maildir/subscriptions As you can see: the cur,new,tmp dir don't have the right permissions (they're not rw for the group), and moreover, the 'subscriptions' file has the same problem. The result is that any other user don't have access to this directory even if it is in a public namespace. Now, the question, is: is that setup could work only with virtual users setup with a static uid/gid ? Is there a mean to implement what I want ? Does using symlinks instead of the namespace could work ? Regards, -- Brice Figureau <brice+dovecot(a)daysofwonder.com>

[Dovecot] mbox to maildir conversion - good idea regarding Outlook?
by Gerhard Hofmann 14 Mar '06

14 Mar '06

Hi list, first of all, many thanks to the Dovecot authors for supplying an IMAP server that works well with M$-Outlook! I have used UW-imapd for quite a while and was annoyed by frequent "imap...timeout..." error messages. Now I'd like to give maildir format a try because I want to use email sub-folders. What are other Outlook users' experiences with maildir? Is it as stable as mbox? Regards Gerhard

[Dovecot] tls
by lenny＠edpausa.com 13 Mar '06

13 Mar '06

is it possible to turn off TLS and only SSL ? The reason are many reasons for this, one major being the fact that TLS is automatically discovered by many clients on the standard ports, thus requiring a valid cert for production use, while SSL could be set up on some unknown to anybody port with self signed cert for testing, etc... thank you

Hello, we have problems to access our users mailboxes with SquirrelMail. The log file /var/log/mail.log says permission denied, only one user is allowed to read his mail with SquirrelMail. We are running Debian Sarge, Mailserver is Postfix, imap server is dovecot. Our Mailboxes are stored in the mbox format. Folder of the mbox files is /var/mail/ the users are unix system accounts. Normally we read are mail with the POP-Client Outlook, this works well. But we also want to be able to read our mail (each user his own mails) via SquirrelMail /var/log/mail.log says: Mar 13 10:54:40 webserver dovecot: imap(unix-system-account): mkdir_parents(/var/mail/.imap/INBOX) failed: Permission denied In the folder where the mbox files are stored exists 3 folders called INBOX.drafts INBOX.sent INBOX.trash These folders are owned by the user who is able to read his mail via SquirrelMail and owned by the group mail. Only the user has read and write permissions. Does each user need to have his own INBOX Files? Could you please help me Kind regards, Roland

[Dovecot] Limiting Dovecot access by user-spesific ip addresses?
by Timo Neuvonen 13 Mar '06

13 Mar '06

Hi, Is there any possibility to limit access to mailboxes by user-spesific ip addresses? So, I'd like to have a configuration which by default restricts reading emails to company's own ip-address range. So far, this could be achieved by a basic firewall rule, but not any more the following: However, there is need for a few users to access their emails from world-wide internet, so there should be a possibility to define for certain users an option to skip the allowed address range check.

[Dovecot] Suggested patch: retain user's group privileges after logging into IMAP
by Lior Okman 11 Mar '06

11 Mar '06

Hi, I'm attaching a suggested patch that lets an authenticated user access shared IMAP folders even if the user doesn't directly own the storage, but is a part of a group that has permissions on the storage. This allows for the administrator to setup a shared mailbox with permissions given to a group instead of a user, and allow all of the users that belong to the group to access the mail according to the file-system permissions. What do you think? Is this the right way to do this, or am I missing something security-wise? I'm also attaching a bug fix for the LDAP passdb, where if the password scheme wasn't PLAIN, the password would be cleared from memory before being used to authenticate the user, and the authentication would fail. Regards, Lior

[Dovecot] Segfault problem when using TWO dovecot servers!
by Adam M. Dunn 10 Mar '06

10 Mar '06

Forgive me if this gets submitted twice. I had issues signing up for the listserv but I think I'm strait now. Hi all, I just started working with Dovecot and I'd like to use it for my organization, but I've run into a little problem. So far I love it and it does what I need. One thing we need is to be able to write to multiple mailbox formats on a per user basis (mbox or Maildir), and it does just that. I want users to be able to choose their format, and I can let it autodetect for me. The way I do that is I have Maildrop filters check for the presence of a ~Maildir, and if it finds that it writes to it, otherwise it writes to ~mbox. Dovecot is the only IMAP server I've found to read either or without hard coding one or the other in the config file. The problem: We also want failover. Mail/home directories are NFS mounted. I was planning to setup two dovecot servers, and noticed that whenever one server writes its temp files to the mail directory, if another server tries to read it you get a segfault and the child process fails and dies. So it basically looks like only one server can own the files, and it won't share. I considered trying to set the INDEX option on the mail boxes to write local indexes, but if I try to specify something like: default_mail_env = INDEX=/var/indexes/%d/%n, it doesn't work. Sure I can make it work by putting in a mailbox format before the INDEX, but then I can't use the autodetect which I need. Here's the syslog error: kernel: imap[13689]: segfault at 00007fffffe38000 rip 00002aaaaad3823f rsp 00007fffffe351f0 error 4 Any solutions? I really need this to work badly, or we may have to rethink our entire mail strategy. I'm also using the latest version 1.0beta3. I considered namespaces, but correct me if I'm wrong, you can't setup two namespaces and have it pick the first mailbox format available like the autodetect feature does. I tried seting up namespaces for both mbox and Maildir, but it just creates both. Please help someone. I need a solution to present to my boss, even if that means we have to run one server until the bug is fixed in the next version. Thanks, Adam

[Dovecot] POP3 extension to accept UIDL ranges?
by Matthias Andree 10 Mar '06

10 Mar '06

Greetings, is anybody aware of an extension to POP3 that supports UIDL ranges? It would be very useful for keep-messages-on-server setups (yes, I know, IMAP4 domain) to be able to do UIDL 21-42 to obtain just these 22 UIDs (this would always have to be a multi-line reply, just like UIDL without argument). If such a thing does not exist yet, perhaps a keyword such as "[X]UIDLRANGES" in the CAPA response might advertise this feature to clients. Regards, -- Matthias Andree

[Dovecot] Two namespaces with same prefix.
by Václav Haisman 09 Mar '06

09 Mar '06

Hi, I have yet another problem. First let me explain my setup. I used to use pine a lot so there are mbox mailboxes in ~/mail. Recently I added a Maildir too and moved most of the mbox mailboxes into Maildir format. Now I thoght it would be nice to have them all "in line" in Thunderbird so I tried this configuration: namespace private { separator = / prefix = location = %h/mbox inbox = yes } namespace private { separator = / prefix = location = maildir:%h/Maildir } The problem is that with this configuration I cannot access the ~/mail/box mailboxes. Thunderbird responds with "Mailbox doesn't exist: box" Is such kind of configuration with two namespaces having same prefix unsupported? Vaclav Haisman

[Dovecot] Default SELinux policy on Fedora FC4 prevents dovecot service from starting
by slohcine＠verizon.net 09 Mar '06

09 Mar '06

Hello, I recently setup a Fedora FC4 server to host e-mail and webapps. During the install, I turned on SELinux in active mode. All apps seems to work OK but Dovecot daemon won't start. In the audit log, I see this entry when I try to start the dovecot daemon. type=AVC msg=audit(1141464818.541:40305): avc: denied { read } for pid=1989 comm="dovecot" name=dovecot.pem dev=md2 ino=3646976 scontext=system_u:system_r:dovecot_t tcontext=system_u:object_r:cert_t tclass=file type=PATH msg=audit(1141499436.214:3266533): item=0 name="/etc/pki/dovecot/dovecot.pem" inode=3646976 dev=09:02 mode=0100600 ouid=0 ogid=0 rdev=00:00 I put SELinux into permissive mode and Dovecot works OK. Looks like dovecot does not assume the correct security context when it initializes and reads the cert file. My question for the list is what changes should I make to the SELinux policy to safely permit dovecot to read the file? I'm no expert at SELinux but hoping for some direction, or another way to solve this problem. Ideally, I'd like to keep SELinux in enforcing mode. Many thanks, Eric

[Dovecot] MySQL problem when using Dovecot as proxy
by Christian Jensen 09 Mar '06

09 Mar '06

Hi, I have just installed Dovecot as a POP3 proxy with great success. Its works flawlessly when i keep to the standard but since I am proxying a Microsoft Exchange 2003 (because the build-in POP3 in MS sux bigtime) I would very much like to use account names like: DOMAIN\username and this doesn't work when I include that in the MySQL table. In the logfile it clearly writes DOMAIN\username so its some kind of translation between dovecot and MYSQL. Any suggestions. I another solution would be to allow all users instead of having to create them in the MySQL table. Is this possible ? /Christian P.S Before Dovecot some Outlook users could only download max. 250kB through POP3 - now with Dovecot there is NO LIMIT! :)

My problem is that I can't get :INDEX and :CONTROL working at all: default_mail_env = maildir:~/:INDEX=/home/dovecot/index/%d/% n:CONTROL=/home/dovecot/control/%d/%n ls -l /home/dovecot/ total 8 drwxrwxrwx 3 dovecot dovecot 4096 Mar 8 07:52 control drwxrwxrwx 3 dovecot dovecot 4096 Mar 8 07:55 index (I've made everything 777 for testing) The error I get is: Mar 8 09:54:26 host imap(user(a)domain.com): mkdir (/home/dovecot/index/domain.com/user/.INBOX) failed: Permission denied If I su to the user(a)domain.com user I can manually create the directory OK. I'm using LDAP for authentication if that makes any difference. Any clues? Pointers? Need more information? -- Karl Latiss <karl.latiss(a)atvert.com.au> Atvert Systems

[Dovecot] Can I install in the following fashion?
by Stewart Dean 08 Mar '06

08 Mar '06

<permit me my perhaps foolish preference...an explanation> I run mail service for a small college. I've long joked that if someone stole the mail server, the phone would ring before the alarm (which has a 1 minute delay) did, that the user base expected 25x8x367 coverage. Making updates/upgrades to the mail server feels like a tightrope walk with no net. I always appreciated UofWIMAP because there is one binary. Doing and upgrade or backing it out is simplicity itself. I could compile the single binary on my compile machine, test the same binary on my testbed, and then drop it in my production machine and it would work with a minimum of surprises. So portable, so predictable, no security risk of a compiler on a production machine. Of course, /most/ of open source software has all these bits and pieces scattered everywhere. Oh, it may install initially just dandy, but come the day when It's Time For The Upgrade.... 1) can I do it quick and clean and 2) can I recover to what I had before quickly and correctly if the upgrade flops?????? Alas, Dovecot is sprinkled in many, many pieces...but at least, I think (right?) that they are all in the prefix-dir. Gulp. So. I am hoping I can do this: Build/Test Install 1) build/install in /usr/local/dovecot_bld/ Build### in the expectation that everything will be stuck down there. I don't want to put it into /usr/local/ because it will be in there with everything else....no way to get just the dovecot stuff.. 2) tar up the contents of my prefix directory and extract it over on my testbed under /usr/local/dovecot. Notice that the path to dovecot's "stuff" has changed from /usr/local/dovecot_bld/ Build### to /usr/local/dovecot I'm hoping that this won't be a problem. I will point the line in inetd at it and Everything Will Work. 3) Assuming I don't change anything and everything tests out (flawlessly!), I............. Introduction to Production (assuming that all the mailboxes, homedirs and the like have been sorted out) 1) make a tarball of the current working dovecot executables dir (/usr/local/dovecot) 2) extract the tarball there as before on the testbed machine and everything is fine. 2) if the update flops, I can bring back the tarball of the previous Dovecot incarnation My Questions: A) Will this work or are there dependencies I'm not aware of? B) Is there Some Better Way or..... I have this ongoing <ahem> discussion with the Open Source wonks that delight in many, many modules, libraries, etc. I /know/ the reasons a developer would want to do things that way, but, for those of use fielding the application, it's /so/ much easier and success/failure recovery is /so/ much more likely if....there are only one or two or three chunks that we can drop in or quickly back out. I realize that the developer is coding in large part for the utter joy of creating a wondrous, living, breathing edifice of code, that works, that works cleanly, that works as none has before. Yes. But I would think (IMHO) that the developer would receive a greater portion of the ego rush (also a big part of the developer stimulus) of overwhelming application acceptance (and thunderous applause), if he or she made it easy to support and upgrade! You see a sysadmin is so often an utter coward (I confess), who doesn't like unpleasant surprises, whose managment Really Doesn't Like Unpleasant Surprises. When I do my job really well, nobody knows I've done anything. OK...let me have it. -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Busy studying
by Timo Sirainen 08 Mar '06

08 Mar '06

In case you're wondering why I haven't answered your mail. I try to do as much reading to exams as possible, and as little as possible anything else.. They're over in 2,5 weeks, so I'll start reading the old emails again then. :) BTW. If someone wants to help a bit, outlook-idle workaround seems to be broken. The timeout function never gets called in cmd-idle.c. I'm guessing it broke after I added the other timeout function for printing "OK Still here" message every 2 minutes, so the bug is probably in timeout handling in ioloop.c.

[Dovecot] Simple Question
by Charlie Davis 08 Mar '06

08 Mar '06

Brand spanking new to Dovecot. Trying to move over to it, got a few simple questions. 1) Is there any documentation on the .customflags file? Not sure what this is for... 2) I'd like to make a directory for every user NOT be writable. Meaning the email server (Exim) can put the mail down in the directory but a user can no move an email into it through Imap. I couldn't find a search for the mailing list either, so sorry if this has been asked 92380498 times. -Charlie

[Dovecot] Special treatment of ~/mail directory

Hi, would it be possible not to treat ~/mail specially and not to add mailboxes in the directory automatically? It would make migrating from IMAP-UW easier. Vaclav Haisman

[Dovecot] Dovecot with mbox and maildir
by Dario Ale 08 Mar '06

08 Mar '06

Hello, I have a question, i need migrate from old mail server to new mail server, the mailboxes format in the new mail server is maildir, in the old is mbox, the problem is that only the INBOXs are approximately 64Gb (are 7000 users), in the new I installed Dovecot, in the old is UW-Imap. The question is, Is there any form for have mbox and maildir simultaneously with Dovecot? I am using Postfix, my MDA is procmail, this write mailbox in the correct format, then i can copy all INBOXs and HOMEs to the new mail server, and change the mailbox format "slowly", supposedly procmail detecting the mailbox format and Dovecot could detect too. Thanks, very much. pd: sorry, my english not is good. -- Dario Ale (dario.a en telpin.com.ar) Area Internet Telpin - Jason 1026 - Pinamar (7167) www.telpin.com.ar

[Dovecot] self-signed certificates
by Benjamin 08 Mar '06

08 Mar '06

Hallo, i'm having troubles installing self-signed certificates for dovecot. After installing, dovecot generates a key and cert. But he is using the wrong common name (where does dovecot get this name from?). I tried deleting them and installing a handcrafted cert with this: openssl genrsa -out mail.key 2048 openssl req -new -key mail.key -out mail.csr openssl x509 -req -days 4312 -in mail.csr -out mail.cert -signkey mail.key after that i tried to update the dovecont.conf to point to the new files. But dovecot refuses to read them, i allways get an error, that dovecot can't read the certificate file. With dpkg-reconfigure dovecot-common, dovecot generates new ones, and they are working fine, but have the wrong common name. Thanks in advance Regards Benjamin

Will that be a problem? I'm not sure, but I think this setting is used for compile time - it's where dovecot expects to find include files, it doesn't mean that anything will be installed there. If you're really concerned, then use "make -n install", and go over the commands that make would have run, you will be able to see exactly where everything goes. Or you could run "make install" inside a chroot jail. I also seem to recall that I saw a script somewhere that could trace the "make install" procedure and print exactly where it puts everything. It was being used for converting .tar.gz "make-based-installations" to rpms. > Q2: Will dovecot not be able to find system resources it needs? Dovecot should be able to find everything it needs, assuming the configuration files are ok. > Tar'ing up a directory is doable. RPM'ing hundreds of files scattered > here and there, perhaps referenced by others, perhaps with new > additions/deletions you don't know about sounds like an heroic task. Tar`ing a directory is doable, but doesn't lend itself well to reusing components and sane system management. When you use RPM/DPKG for manging your configuration, each package you install is responsible for its own files and nothing more. The packaging system makes sure that nothing conflicts or overwrites existing files. If you accidently untar a file with bad configuration files in it, they will probably overwrite your existing configuration. RPM/DPKG will save your old configuration files. Tar can't help you verify that what you installed is what is actually running. RPM -verify can make sure that no trojan has been installed instead of a file provided in an RPM file. And the list goes on and on. > Does anybody see how simple it is to upgrade UWImap with its one binary? Just as long as there is only one binary. AFAIK, UWImap doesn't support configuration files, on the assumption that the sysadmin probably doesn't know enough to create a valid configuration. The downshot of that is that there is a limit to what you can do with UWImap's one binary :-) Lior > > Lior Okman wrote: > > Looking at the debianized version, the bulk of the files are placed in > > € > > or under /usr/lib/dovecot, with all of the configuration files in > > € > > /etc/dovecot, and relevant binaries under /usr/bin and /usr/sbin. > > € > > > > € > > However, reading from the comment in the begining of the default > > € > > dovecot.conf file, you can probably compile your own version of > > € > > dovecot where you specify the following parameters to configure: > > € > > "--prefix=/usr --sysconfdir=/etc --localstatedir=/var > > € > > --with-ssldir=/etc/ssl". > > € > > Just make sure to replace all the paths with where you want to install > > € > > this version of dovecot. > > € > > > > € > > Lior > > € > > > > € > > On 3/7/06, Stewart Dean <sdean(a)bard.edu> wrote: > > € > > > >> Hmmm, hadn't thought of RPM.

[Dovecot] dspam plugin mailing list?
by Johannes Berg 07 Mar '06

07 Mar '06

Hi, Every once a while I get mail about my dspam plugin. While that's great (tells me people are using it or at least like the idea), sometimes I think the discussions then should be accessible to others. I'm thinking of setting up a new mailing list for it so answers get archived, are searchable, and I don't necessarily have to reply to everything. I'm not sure if that's feasible though, there probably aren't *that* many users, and sometimes the questions are more dovecot questions. Would anyone on this list (esp. Timo of course) mind if I were to note on the plugin page that discussion and questions should be sent to this (the dovecot) mailing list? I'll still be reading here and answering questions, of course, but then if something crops up that's more dovecot than plugin related it's at the right place already, or if I'm off for a few days and someone else knows the answer... If there are any objections I'll just set up a private mailing list instead and ask anyone interested to join (it'd be very low volume I guess) :) johannes

[Dovecot] mbox sync: UID inserted in the middle of mailbox...
by Simon Bowden 07 Mar '06

07 Mar '06

Hi, We're getting a lot of errors like this: Mar 7 10:02:35 imapserver dovecot: imap(user1): mbox sync: UID inserted in the middle of mailbox /home/user1/mail/mail/INBOX.Trash (8 > 2, seq=2,idx_msgs=6) We have several hundred people using the server, and at least 22 have had this error in the past 24 hours. The numbers at the end change between each user, which I guess you'd expect. I was able to make the errors go away for one user by removing the index files (rm -rf ~/mail/.imap/INBOX), so I'm guessing they were corrupt. However, the problem with this is that: 1) It requires user intervention 2) The symptom is that they aren't seeing any new mail in the affected mailbox. I had thought that the indexing stuff would not *give up*, but would reindex a directory if there was a problem. Anyone able to help? Some info on our setup: /home/user is nfs-mounted. We allow them to configure their mbox/maildir type and location, but obviously this is only relating to mbox ones. Here's the config file, stripped of comments and blank lines: ==================== protocols = imap imaps ssl_cert_file = /etc/ssl/certs/imapd.cert ssl_key_file = /etc/ssl/private/imapd.pem ssl_ca_file = /etc/ssl/certs/cacert.pem log_timestamp = "%Y-%m-%d %H:%M:%S " login_processes_count = 6 first_valid_uid = 40 mail_extra_groups = default_mail_env = mbox:~/mail/:INBOX=~/.incoming-mail mmap_disable = yes mail_drop_priv_before_exec = yes protocol imap { mail_executable = /usr/local/mail/imap-wrapper imap_client_workarounds = outlook-idle delay-newmail tb-extra-mailbox-sep } protocol pop3 { } auth default { mechanisms = plain gssapi passdb pam { args = session=yes * } userdb passwd { } user = root } plugin { } ==================== /usr/local/mail/imap-wrapper is just a script that lets them configure the setup a bit (effectively change value of MAIL, and some namespace stuff), ultimately running /usr/lib/dovecot/imap. The nfs mount options on the home directory mount are: rw,hard,intr,rsize=8192,wsize=8192,nosuid,nodev,vers=3,proto=udp Thanks! Cheers, - Simon

[Dovecot] Dovecot as a smart IMAP proxy
by Timo Sirainen 07 Mar '06

07 Mar '06

Do you see a use for an IMAP proxy where the proxy would be able to execute hooks which modify mail contents, such as transparent encrypting/decrypting mails, or maybe some virus-filtering? It would need at least some kind of IMAP command/reply parsing capabilities, so it might be able to do all kinds of other things. Maybe one potential use case would be Cyrus Murder-like proxying to multiple IMAP servers to distribute the mailboxes. But that might be done better as an imap process plugin, or maybe as IMAP mail storage backend. Anyway, the reason I'm asking this is because I was asked to add mail encryption/decryption capabilities to Dovecot's IMAP proxy, but I'm not sure what would be the best way to handle this. In any case it would be a plugin or a new binary which is executed instead of imap binary, but can I do it in a way that would actually be useful for Dovecot project in general?

[Dovecot] [IMAP] Strange! No problem when I import mails from local to server.
by Xueron Nee 07 Mar '06

07 Mar '06

Hi, All: I hava just post a question that says when I move mail from one folder to another, mails were holded in the tmp directory of the target folder. I try to move mails from server to local and then, move them from the local folder to the server side folder, it works fine :) I refresh the tmp directory and could see tmp files created-unlinked, and all mail imported to the target folder currectly. What's the problem when I move mails between server-side folders? -- Xueron Nee <xueron(a)gmail.com>

[Dovecot] [IMAP] mails holded in tmp directory

07 Mar '06

Version: 1.0.beta3 OS: Redhat AS 4 I use the cvs version of Dovecot to run my IMAP server.

I use becky and Outlook as client, and both of the two have the same problem. Thanks :) -- Xueron Nee <xueron(a)gmail.com>

[Dovecot] Shared Folders (1.0beta3)
by Timothy White 07 Mar '06

07 Mar '06

A few quick questions, as documentation seems to be sparse. * Is there a way to force a shared folder to be subscribed to? If I am using SquirrelMail I have a plugin to do that, but not if they are using another IMAP client. * Are there some sort of ACL's on shared folders, so that I can (hopefully with a sql backend), allow different users different permissions on the folder? * Is it a bug that we can't subscribe to the shared folder, only to it's sub folders? (and is there a way to work around this, i.e. if the shared folder isn't really a Maildir, but it's sub folders are? Other than that, so far, my glimpse at 1.0beta3 is looking very good, and came at the right time, as I was thinking I might need to use Cyrus for the project I'm working on atm...

[Dovecot] using mbox but, can't create subfolders
by blaq b0x 07 Mar '06

07 Mar '06

Hi, I'm using mbox format w/ dovecot 1.0b3. I tried moving over my mail from a uw-imap server. Everything works fine except I can't create subfolders. Is there something I'm doing wrong or is this a limitation of dovecot? How can I fix this? Thanks, --------------------------------- Yahoo! Mail Bring photos to life!

[Dovecot] convert tool
by lenny＠edpausa.com 06 Mar '06

06 Mar '06

Trying out the new convert tool, to migrate from mbox to maildir. Using this syntax ( both inbox and folders are in user's home dir, in mbox format ) ./convert-tool pinetest/export/home2/pinetest \ mbox:/export/home2/pinetest/:INBOX=/export/home2/pinetest/mbox \ maildir:/export/home2/pinetest/Maildir/ I get this error. "Error: Mailbox conversion: Couldn't create mailbox home/Trash Error: Internal failure" Where does it get home/Trash from is hard to guess. I'm not using any variables, every path explicitly says "/export/home2/pinetest" Any ideas ?

[Dovecot] How to create .dovecot.sieve through IMAP?
by Sergey A. Lipnevich 06 Mar '06

06 Mar '06

Hi All, I suspect that the answer is "no way," but there's hope. I'm trying to set up a PHP application Ingo (part of Horde suite) to create the file <home>/.dovecot.sieve for the "advanced" LDA to do mail sorting. Because PHP is running under a Web server user, Ingo can't really write this file directly. My question is, is there any way for Ingo (or any other tool, for that matter) to create that file via IMAP protocol interaction? Horde authenticates users and "knows" login/password combination (that's how it accesses mail folders). Thank you! Sergey.

Just got dovecot running inside MEPIS 3.3.2 SOHO (debian). I am impressed. It works really well and I am planning to move my mail away from my Win server and access the mail from dovecot using imap. I have copied some folders from my existing Outlook mail system into the imap mail server without any problems....so here is the dumb question: where are the mail files/folders stored on the MEPIS server? I have been all over the file system and cant find any files that look right. The dovecot doco talks about mail location for the index files - but I have looked in all of those and cant find anything. The MEPIS system has a Maildir for the user......but that looks just as it did at install: contains three folders, cur, new and tmp all of which are empty :( Please dont flame - I have looked and I did try to find the answer but I although I can see the folders and messages through the imap client I cant actually find anything on the server.......and I would like to see something before I turn my Win mail server off.

[Dovecot] Apple Mail cannot connect (1.0 beta3)
by Gregory K. Ruiz-Ade 03 Mar '06

03 Mar '06

I'm testing 1.0 beta3 on our mail server, and finding that Apple Mail seems unable to connect to it. I'm running the 1.0b3 on port 997 so we can test it in parallel to 0.91 to compare performance (so far, it's hella faster). I've ensured that the users testing are _not_ connecting in any way to the 0.91 version running on port 993. From the OS X client side (10.4.5 + latest patches), Apple Mail simply sits there and spins, and eventually times out. The error it gives is: ----- Alert There may be a problem with the mail server or network. Check the settings for account "UCSD" or try again. The server error encountered was: The connection to the server "csefast.ucsd.edu" on port 0 timed out. ----- I'm thinking, "port 0, WTF?" ... On the server, I get this out of the logs: ----- Mar 2 11:54:48 csefast dovecot: imap-login: Disconnected: Inactivity: rip=<client_ip_address>, lip=<server_ip_address>, TLS Mar 2 11:54:48 csefast dovecot: imap-login: SSL_accept() syscall failed: EOF [<client_ip_address>] ----- Apple Mail is configured to connect to port 997 and has "Use SSL" checked.

[Dovecot] Thunderbird 1.5 and dovecot 1.0 beta 3 problem
by Peterg 03 Mar '06

03 Mar '06

My mailhosting provider has been testing dovecot 1.0 beta 3 as a proxy server and they asked the customers if they would like to test it out and report any issues. I am using Thunderbird 1.5 (IMAP) and have been with this mailhosting company for two months and have no issues at all with their current setup which uses Perdition as their proxy servers. The problem(s) I am encountered have been reported here a few times previously over the last couple of years but in searching I have not found any concrete solutions. When I first tested it out there was a continuous problem of a failure in saving a copy of an email to the sent folder although the message was sent. One of the staff of the mailhosting company noted this exact problem as well and believed the issue was Dovecot announcing different IMAP capabilities than the real backend IMAP servers (via the CAPABILITY command). This was supposedly fixed and initially there were no issues with the first set of test emails. However, in short order, this problem re-emerged and there would be sporadic failures to copy a message to the sent folder. Another issue would be that every now and then, when clicking on a folder in the left-hand pane (and no other activity going on with Thunderbird like downloading a new mail) Thunderbird would hourglass for 10-15 seconds as if it were trying to open a connection and was having difficulty. The maximum number of connections setup in Thunderbird is the default 5 and I am advised that this is the correct setting with their servers. Reducing the maximum number of connections does not appear to change matters in terms of avoiding these problems. Changing back to the current system (ie not using the test proxy server) both these issues disappeared. I have been in communication with the mailhosting provider as to my findings but it would be most appreciated if others here would perhaps have some insight into this matter. Peter

[Dovecot] maildir locking and 'racing'
by William Ross 02 Mar '06

02 Mar '06

hello Timo, list, quick error-message question. A few of the accounts on my main mailserver are failing to log in with errors like this: dovecot: Mar 02 19:33:35 Error: imap(user(a)example.com): maildir_file_do(/var/lib/vpopmail/domains/example.com/user/Maildir) racing if I log in by telnet everything is fine, and from the source it looks like the error happens when dovecot fails to get a lock on some important file or other. Could it be to do with concurrent connections? No idea. Has anyone seen this, and can you suggest a quick fix? I can't see any obvious difference between the accounts that work and those that don't :( nb. this is with vpopmail, and the Maildirs have just been moved over from another server that was also running the same version of dovecot. Some of the accounts do work. Perhaps it's just an obscure file permissions problem, or something? I'd be very glad of any suggestions. thank you, will

[Dovecot] Sorting order after mail move
by Václav Haisman 28 Feb '06

28 Feb '06

Hi, when I move some recent mail from some mbox folder into Maildir folder the moved email sorts as the first (on top) in the folder while it should be on the bottom with the rest of the recent emails in the folder. This happens only when moving from mbox folder to Maildir folder. I am not sure if it is really Dovecot bug or not but I suspect it could be so because it only happens in this one specific scenario.

[Dovecot] two possible inboxes, possible to check both?
by adcx＠server101.com 28 Feb '06

28 Feb '06

We're currently in the process of organising a migration from mbox to maildir mail storage on our server, and are hoping to phase this in gradually using dovecot's capabilities. Procmail has already been configured to deliver mail to either the existing mbox or to a new maildir for the user based on the (non)existence of a .converted file in their home directory. Where we are having problems is the pop3 retrieval side of things. Basically, we're chasing a setup where dovecot will first check to see if /mail/<first letter of username>/username exists (indicating that the account has had the .converted file created and new mail has since been delivered to that user in the new maildir format). If this directory does not exist, it should fallback to retrieving mail from the as-yet unconverted mbox, /var/mail/username. We've tried different combinations of namespaces and default_mail_env values to achieve this without success. One attempt which has come particularly close was: 1. Leaving /etc/dovecot.conf almost entirely default. The auto-detection ability of dovecot performs the following (output to /var/log/maillog): Feb 28 14:57:45 mouse dovecot: pop3(joe): maildir: access(/home/joe/Maildir, rwx): failed: No such file or directory Feb 28 14:57:45 mouse dovecot: pop3(joe): maildir: couldn't find root dir Feb 28 14:57:45 mouse dovecot: pop3(joe): mbox: root exists (/home/joe/mail) Feb 28 14:57:45 mouse dovecot: pop3(joe): mbox: INBOX exists (/var/mail/joe) Feb 28 14:57:45 mouse dovecot: pop3(joe): mbox: root=/home/joe/mail, index=/home/joe/mail, inbox=/var/mail/joe Feb 28 14:57:45 mouse dovecot: pop3-login: Login: user=<joe>, method=PLAIN, rip=192.168.6.20, lip=192.168.6.2 Feb 28 14:57:45 mouse dovecot: pop3(joe): Logout. top=0/0, retr=0/ del=0/0, size=0 This is almost exactly what we're chasing, except the new Maildir is not going to be created in the user's home dir, it will be in /mail/<first letter of username>/username. All attempts to make this last adjustment have ultimately modified the behaviour of dovecot so that it only checks the one source explicity given, and then simply fails if it does not exist, unlike the unconfigured behaviour illustrated above where it is able to fallback to a secondary source. A '2nd_default_mail_env' is the type of variable I'm looking to define, if that makes it any clearer. Any advice much appreciated, I've already searched most of the archives for this list without finding anything similar.

[Dovecot] Impact of log files on performance
by vmstech 27 Feb '06

27 Feb '06

Hi - im trawling through my config trying to reduce chances of timeouts etc - I use postgres for all the dovecot and exim4 authentication and location of mail directories etc - and found that by eliminating logging (or reducing to almost none) the queries invovled have gone from >500ms to <3ms - Just wondering if I'll get similar performance gains with dovecot (which is set to be verbose as I could) - esp during connection thx Glenn

Error the server is unavailable. Receiveing Reported error (0x800CC0F):'The connection to the server was interrupted' While these are from outlook - I often get one simiar to the first one in my evolution clients.

[Dovecot] RHEL4 configuration
by f00bar 26 Feb '06

26 Feb '06

I just installed a new email server using RHEL4. I only want pop3d services, no imap is desired so I modified the dovecot.conf file by changing to "protocols = pop3". All is working fine. However, dovecot requires access to /home/user/mail or the Thunderbird client hangs when attempting to download email. We have a single /home that is mounted by all servers for all users. We do not want the mail server to mount this /home. So I created directories with the usernames in the mail server's /home. This is not desired from a system management perspective. The files dovecot creates in the /home/user/mail directory appear to be for the use of IMAP which we do not use. How do I configure dovecot to not access /home and to not create any IMAP files? Thank you
