[Dovecot] Duplicate Attachments....
by Charles Marcus 02 Jun '06

02 Jun '06

Love Dovecot, many thanks for it! But, I have a question regarding the storing of emails, with respect to efficiency... Our business model (advertising industry) is such that our users exchange a lot of emails with attachments - most less than a megabyte, but some considerably larger. Consequently, I have been looking for a good, open source imap server that doesn't store multiple copies of the same attachment - but instead, stores a checksum, and whenever a message is stored with a duplicate attachment, the attachment is stored only once, and simply referenced by some kind of link to other emails. This would *drastically* reduce the storage requirements for our company - imagine a message with a 10MB attachment, sent to 40 of our users, sometimes more than once. Now multiply this by 3 times per day, for 5 years... Are there any plans for Dovecot to support this type of storage in the future? Does this require the use of an SQL DB for storing the message components? -- Best regards, Charles

[Dovecot] Platform change, considerations?
by Peter Lindgren 02 Jun '06

02 Jun '06

Hello! I am switching hardware platform for my dovecot 1.0beta3 installation. From Sun Sparc (SS4) to Intel i386. OS platform will only change from OpenBSD 3.7 to 3.9. From Dovecot 1.0beta3 to beta8. Is there anything special to consider, in terms of endianness or other incompatibilities? I plan on a fresh install (compile) on the new machine, migrate the settings manually (by hand), test the new server and then migrate old mail. Can I just mount the disks and copy, or should I go through NFS to be safe from potential endianness problems? Or perhaps copy with IMAP using my Thunderbird client? The live switch (the old server is in production) isn't that delicate, several hours downtime is OK. There's a backup server that can receive any mail I might loose during downtime, which can be copied though IMAP later. Thanks for any input! /Peter -- Peter Lindgren, dataingenjör E-post: peter "at" norrskenkonsult punkt com http://www.norrskenkonsult.com

[Dovecot] Outlook causes BIG dovecot index problem (beta 8, outlook 2003)
by Casey Allen Shobe 01 Jun '06

01 Jun '06

Hey all, Well, I typed up all the below, then managed to fix the problem before sending this to the list. I'll send it anyways, in case anybody else is affected by it (and because it does indicate a definite bug in Dovecot's experimental Kerberos support). The fix is to recompile without kerberos enabled, and to take gssapi out of the auth methods in the config (the latter alone may or may not be enough of a fix on it's own, I didn't try it without recompiling). I'm guessing that Outlook attempts to use Kerberos authentication by default or something and silently fails and uses other auth methods, and that any attempt to use Kerberos is in fact what hoses the server. However I have not done any further testing against beta8 with a Kerberos-enabled client such as KMail, so I leave this as an exercise for the next adventurer. I'm also uncertain as to why this problem does not manifest on our main servers, which also have Kerberos enabled (and Outlook 2003 clients). Or /had/ anyways, as I'm disabling Kerberos support as we speak as a preventative measure. Here's the problem description: I've been running dovecot happily for many months on our production mail servers hosting about 600 accounts, with no problems. People use every mail client under the sun - Apple Mail, Outlook 97|2000|XP|2003, Outlook Express, Mutt, Thunderbird, Mozilla Mail, Eudora, and other esoteric things with no problem. So today I installed a new mail server on a client site dedicated to their domain. The MTA is exim, running with almost the same configuration we use on our main servers. The dovecot.conf is 100% identical. No mail was moved by hand to the new mail server - to migrate we copied the mail setting up the old and new accounts in Thunderbird and dragging things over (just to rule out that possibility, we have also tested using brand new empty accounts to reproduce the issue). Everything is golden using Thunderbird - email is send, and shows up in the inbox immediately. Enter Outlook 2003 (SP1): It shows all folders and mail fine. It sends mail fine. Nothing shows up in the inbox. At this moment, Thunderbird also stops receiving new mail in the inbox. I check the server, and there's a mail sitting in the /new directory in the maildir. Not only that, but suddenly NONE of the accounts on the box show any new mail, exhibiting the same signs. I tried a variety of things, including 'sync', removing all the dovecot* index files in the maildir, and restarting dovecot (being sure to killall imap before bringing it back up). Sometimes, these steps would magically cause everything to work again, until I did a mail poll in Outlook which causes the problem to re-occur. Other times, these steps didn't seem to do anything. A couple times, for no apparent reason, without doing anything, mail would show up. Too hopeful, we sat around for 30 minutes sending more mail to an account and then just idling...nothing showed up. The hardware is good, we've compiled a full glibc and gcc just to ensure that there are no CPU/memory issues, and this box has a solid good history behind it in it's prior uses. Until Outlook is used, everything works fine. We do have the outlook-idle workaround enabled, and tried both with and without delay-newmail, which didn't make any difference.

[Dovecot] mbx to mbox conversion
by Marc Perkel 01 Jun '06

01 Jun '06

Here's a feature I'd like. If Dovecot opened an MBX format file that it would convert it to an MBOX format file. I have several files that I'm having a hard time converting. The one I got from Washington University WUIMAP is extremely flawed.

[Dovecot] Cannot remove Maildir folder
by Marcin Deranek 01 Jun '06

01 Jun '06

Hi, I have been using dovecot 1.0 beta 8 on Debian Sarge for a couple of days and I experienced some problems when removing folders.. As an IMAP client I use Thunderbird 1.5 and IMAP folders are on NFS. Here are the steps to re-produce the problem: 1. Run Thunderbird as usual 2. Create folder 3. Remove folder - In my case folder is not removed but moved to Trash (Thunderbird setting) 4. I go to Trash and remove it from there 5. Folder is removed but I get additional ..DOVECOT-TRASHED directory - next time it won't be possible to remove it Some more info: * Just before removal I run lsof to see which files are in use: bash# lsof /home/marcin ... imap 21360 marcin cwd DIR 0,15 344064 3307008 /home/marcin (filer:/vol/vol0/home/marcin) imap 21360 marcin 8u DIR 0,15 4096 4223651 /home/marcin/Maildir/.Trash.test/new (filer:/vol/vol0/home/marcin) imap 21360 marcin 9u DIR 0,15 4096 4223650 /home/marcin/Maildir/.Trash.test/cur (filer:/vol/vol0/home/marcin) imap 21360 marcin 11r REG 0,15 144 4223663 /home/marcin/Maildir/.Trash.test/dovecot.index (filer:/vol/vol0/home/marcin) imap 21360 marcin 12r REG 0,15 104 4223647 /home/marcin/Maildir/.Trash.test/dovecot.index.log (filer:/vol/vol0/home/marcin) imap 21360 marcin 13u REG 0,15 10272 4223657 /home/marcin/Maildir/.Trash.test/dovecot.index.cache (filer:/vol/vol0/home/marcin) ... There are more files in use but in this case I'm interested with PID 21360 which has opened Trash/test (the one which I'm going to remove) * Just after removal I see error message in Syslog: dovecot: IMAP(marcin): unlink_directory(/home/marcin/Maildir/..DOVECOT-TRASHED) failed: Device or resource busy Running lsof again gives the following: imap 21360 marcin cwd DIR 0,15 344064 3307008 /home/marcin (filer:/vol/vol0/home/marcin) imap 21360 marcin 11r REG 0,15 144 4223663 /home/marcin/Maildir/..DOVECOT-TRASHED/.nfs004072af0002cb1b (filer:/vol/vol0/home/marcin) imap 21360 marcin 12r REG 0,15 104 4223647 /home/marcin/Maildir/..DOVECOT-TRASHED/.nfs0040729f0002cb1a (filer:/vol/vol0/home/marcin) imap 21360 marcin 13u REG 0,15 10272 4223657 /home/marcin/Maildir/..DOVECOT-TRASHED/.nfs004072a90002cb1c (filer:/vol/vol0/home/marcin) Looking into some NFS docs we can read: "A client has a file opened. Another process on that client deletes the file. So the client NFS stack rather than deleting the file and potentially hurting the other process, it renames the file to .nfs<file_handle>." To me it looks like one imap process tries to delete .Trash.test directory (first rename and then unlink) whereas other imap process has still opened dovecot.* files. Any workaround/fix for that ?

[Dovecot] dovecot.index.cache
by Fintec 31 May '06

31 May '06

Hopefully someone can explain/help me with the dovecot.index.cache file. I am wanting to move a dovecot server (v1.0b7) onto a new box running the same version (1.0b7) of dovecot. To do this I rsync'd the maildir files to the new server but when I logged into the new machine through IMAP dovecot reported: IMAP(username): file index-mail.c: line 105 (index_mail_get_fixed_field): assertion failed: (buffer_get_used_size(buf) == data_size) As soon as I delete the dovecot.index.cache file within the users mailbox this error goes away. Great, but that now I have some questions: 1) Does the dovecot.index.cache file store/cache server specific settings? If not why did it cause this error on the new box with exactly the same dovecot version and dovecot.conf? 2) What will happen if I delete the dovecot.index.cache file for all users? Will POP3 users have to re-download all their mail or will dovecot simply reference the dovecot.index file in the absence of the cache file? If I've missed something on the wiki explaining all this please point me in the right direction. Any help would be greatly appreciated. Gavin

[Dovecot] Apple Mail and too many open files?
by Alan Schmitt 31 May '06

31 May '06

Hello, For two days in a row, I've noticed that my dovecot server (hosted on a PowerMac running OS X) has stopped working, with a bunch of error messages in /var/log/mail.log like: May 24 07:31:10 top dovecot: pipe() failed: Too many open files To solve this, I have to kill -9 dovecot and the (many) imap processes running. The only client accessing the server is a machine running Apple Mail. I tried to increase the limit in the number of files (I did a "launchctl limit maxfiles 1024 unlimited", but the problem still happened. Is this a known problem? Should I allow still more files? Thanks, Alan -- Alan Schmitt <http://alan.petitepomme.net/> The hacker: someone who figured things out and made something cool happen. .O. ..O OOO

[Dovecot] How to move a Maildir directory to a new server?
by Darrin Smart 31 May '06

31 May '06

Hi All, I'd like to ask about the best practice for moving a user's Maildir from one host to another. I moved a few user's home directories, and therefore their ~/Maildir folders. They have complained that since the move, they don't see all the messages in their INBOX for a while, but eventually they all appear again. They are using Thunderbird. I tried deleting the index files but it didn't help. Can anyone give advice? I have a soft link pointing from the old home directory to the new one, and both paths were on NFS. I can't see how dovecot could give different results, could it be related to message UID numbers? I did notice that when I moved my own home directory, Mail.app re-downloaded every mail when I opened each folder. Thunderbird doesn't seem to do this, perhaps its related. Thanks. Darrin

[Dovecot] public folders aren't public
by Mark Nienberg 30 May '06

30 May '06

I'm testing dovecot as a replacement for an aging UW-IMAP server. I have the basic IMAP setup working but I'm stuck on public folders (which my users are addicted to). I set up public folders generally a described in the wiki. The problem is that when a user creates a new public folder, the folder is owned by the user with permissions drwx------ which prevents other users from viewing the contents. Here is part of dovecot.conf: namespace public { separator = / prefix = Public/ location = maildir:/home/public/Maildir } and here is the Maildir directory [root@tesla Maildir]# ls -la total 70k drwxrwxrwx 7 dovecot Everyone 4.1k May 12 14:33 ./ drwxrwxrwx 3 root root 4.1k May 12 13:43 ../ drwxrwS--- 2 dovecot Everyone 4.1k May 12 13:48 cur/ drwx------ 5 david Everyone 4.1k May 12 14:33 .davi/ -rw-rw-r-- 1 dovecot Everyone 0 May 12 13:46 dovecot-shared drwxrwS--- 2 dovecot Everyone 4.1k May 12 13:48 new/ -rw------- 1 mark Everyone 6 May 12 14:07 subscriptions drwxrwS--- 2 dovecot Everyone 4.1k May 12 13:48 tmp/ drwx------ 5 mark Everyone 4.1k May 12 14:30 .tryit/ The directories .davi/ and .tryit/ were created by users david and mark respectively.

[Dovecot] IMAP server <defunct> (beta 7)
by Graham Briggs 30 May '06

30 May '06

Hi, We've been using a 0.99 version of Dovecot for nearly a year without problems, but due to a server death I had to reinstall with the same configuration as before, but more recent versions of the software, on different hardware. This time though, every few days IMAP login and access fails, and the output of ps ax shows entries such as [imap-login] <defunct> and [imap] <defunct>, with the lovely brain-eating Zombie status. There is nothing in the log file that suggests an issue. We're using dovecot with authentication/etc being done against a Postgresql database. I searched online for a solution, but the nearest problem said it was a problem with PAM, which we are not using with Dovecot. We're using Maildir as the message storage format. Does anyone have any suggestions as to why this might be occurring? If it will help to see the dovecot configuration files then I can provide them. The platform is Debian 64-bit running on a dual-core Opteron system. Yes, it isn't Debian-stable! Graham

[Dovecot] Maildirquota
by Rodolfo Gonzalez Gonzalez 30 May '06

30 May '06

Hi, I'd like to use dovecot+postfix (with Maildir) for several virtual email servers, but one requirement is quota support. I'm aware about the lack of maildirquota support in dovecot, and I found a patch in the "unofficial patches" section which is said to provide maildirquota support to dovecot. How stable is this patch?, is it usable with dovecot 1.0b2?. And, is there any plan to support maildirquota natively in the near future?, I'd like to replace courier-imap in my setup. Thanks. Rodolfo.

[Dovecot] Problems with subfolders in Thunderbird
by Ian Thurlbeck 30 May '06

30 May '06

Dear All Server: dovecot-1.0.beta8 (compiled from source) centos 4.3 Client: thunderbird 1.0.8 on Fedora Core 4 on port 993 Using maildir Normally (with the current UW-IMAP) I can create a folder which may contain only messages or only folders. If I create a folder which will contain only folders, it is listed in thunderbird in light-grey italics. Subsequently I can create message folders within this folder. When doing the same thing using dovecot as the server, the same options are available, but any attempt to create a folder containing only folders is silently ignored and nothing happens (nothing is created anywhere on the server filesystem). Is this a known problem ? I do not want to use the setting which allows you to create folders which may contain both messages and folders.

[Dovecot] Hint for Fatal: sigaction(SIGRTMIN) failed: Invalid argument

Hello, Search google I've found a thread ("errors in logfile") discussing a similar problem to mine. It`s something related to the #define IOLOOP_NOTIFY_DNOTIFY in config.h, but disbling it resulted in errors in compilation. I'm really running out of answers for this one... if anyone could give a hint, it'd be of great help. cheers -- .''`. -- Breno Jacinto : :´` : -- breno /at/ freeunix dot com dot br : ' ' : -- 88AE 3F43 7110 57F6 A206 `. `'` -- D116 02CA 02F4 803D 4294 `-- -- Debian GNU/Linux - The Universal OS

[Dovecot] imap proxy and passwd-like passdb/userdb
by HenkJan Wolthuis 30 May '06

30 May '06

Hi, I'm testing/using dovecot as imap proxy, passdb/userdb as passwd-like-file. It seems to function as expected (1). This setup is described in the wiki in AuthSpecials. But I also noticed in the documentation (ImapProxy / FeatLoginProxy pages) that the proxy feature only works with a sql passdb. Maybe I did something strange, but passwd-like-passdb does work..... So I have some questions: Is the documentation wrong? Is the documentation right? ;-) Are there reasons not to use dovecot this way (other than scalability / maintainability)? Are there bugs I've not yet seen? (am I the only one using dovecot this way?) thanks-in-advance, HenkJan 1) i'm proxying to a courier backend, had to modify dovecots capability_string, because the emailclient gets the capabilities from dovecot, while it uses the proxied server (=courier). Had some strange errors with append, as courier doesn't support Literal+, modifying dovecot so that it stopped advertising Literal+ solved the problem....

[Dovecot] Out of Quota Causing "BYE Too many invalid IMAP commands."
by Timothy White 30 May '06

30 May '06

Doing some testing in Squirrelmail, with quotas, and basically opening a message, and saving it as a draft, over and over until I run at of quota. This is what I get when I try and save a message that is larger than the size left May 30 19:36:36 mafeking dovecot: IMAP(joeblogs): Disconnected: Too many invalid IMAP commands. and in SM ERROR: IMAP server closed the connection. Server responded:* BYE Too many invalid IMAP commands. I would expect something a little more user friendly in that situation. I haven't worked out how to debug the IMAP session in SM, or how to run an IMAP session with logging. I may get around to setting up debug in dovecot to see what happens. I'm running dovecot beta8. Any suggestions as to how to make it 'die' nicer? Thanks Tim -- Linux Counter user #273956

[Dovecot] Leave copy on server problem.
by Dario Ale 30 May '06

30 May '06

Hello, I am using Dovecot 0.99.14-r1 with mbox format. I have a problem with the option "Leave copy on server", the messages are duplicated. I tried many options but I can´t find the solution. The last test was: I modified in src/pop3/commands.c (function list_uids()) the folowing things: "... client_send_line(client, message == 0 ? "%u %u.%u" : "+OK %u %u.%u", mail->seq, client->uidvalidity, mail->uid); ..." by "... client_send_line(client, message == 0 ? "%u %08x%08x" : "+OK %u %08x%08x", mail->seq, mail->uid, client->uidvalidity); ..." then, I removed all index files so this were regenerated, I deleted popstate.dat, after with Mozilla Thunderbird I got the messages. popstate.dat was regenerated too, with the following information: this is the last lines: "... k 000000b14062ffdb 1148496134 k 000000b24062ffdb 1148496135 " After I send a new email and get messages, the last lines in popstate.dat was: "... k 000000b14062ffdb 1148496134 <-- no duplicated k 000000b34062ffdb 1148496827 <-- duplicated of k "000000b24062ffdb 1148496135" k 000000b44062ffdb 1148496828 <-- new " the new messaged arrived and the previous message was duplicated. This problem happens with OutLook Express too. Please, somebody can help me?? Thanks very much. pd: sorry by my english. -- Dario Ale (dario.a en telpin.com.ar)

[Dovecot] Migration problems from Courier-Imap
by Mattia Martinello 30 May '06

30 May '06

Hi, I'm migrating from Courier-Imap to Dovecot-Imapd and I have some problems.. I don't want to change the IMAP folders, so I wish to have Dovecot's compatibility with Courier's IMAP folders. In the Dovecot configuration I configured this: namespace private { separator = . prefix = INBOX. inbox = yes } Dovecot correctly shows me the INBOX folder, but doesn't show me the subfolders anymore... What can I do to solve this problem? Thank you very much and goodbye. Mattia.

[Dovecot] Effect of "login_process_per_connection = no"?
by Pete Slagle 29 May '06

29 May '06

Using dovecot version v1.0.beta8 on FreeBSD 6.1_RELEASE with login_process_per_connection = no in the dovecot.conf file, I still get a new imap process for each IMAP login. That is, if a single user logs in five times, five imap processes are created. The difference appears to be that with a "yes" setting each user login causes a new copy of the imap-login processes to be forked, which then creates the imap process for the connection and exits. With a "no" setting, one of the existing imap-login processes creates the imap process directly (and does not exit). I am understanding the effect of this control setting correctly? Are there other actions or implications? Pete

[Dovecot] Security hole with mboxes
by Timo Sirainen 29 May '06

29 May '06

Unfortunately we have our first problem that could really be counted as security hole. Giving "1 LIST .. *" IMAP command allows the user to see all files and directories under the mbox root's parent directory, so potentially you could see other users' mailbox names. Nothing can be done with them though, so it's not possible to read or modify them. There are also some other less than wanted behaviors that can be done with "." and ".." directories, such as "DELETE .." command can give errors. Also with maildir if you store indexes in different directory than mails this command can be used to delete the index files. Anyway I don't see any of these as security issues. Hopefully most people have their mail directory under user's home directory, so this would only list the home directory's contents. But if you do have users' mails stored in eg. under /var/mail/%u/ directory, giving that command would list everything under /var/mail, assuming that the process has permissions to do that (that's why you should be using different UIDs for users if possible). This affects 1.0 beta and 1.0 stable releases, but not 0.99.x. Fix is in http://dovecot.org/list/dovecot-cvs/2006-May/005563.html I'll also release 1.0 beta8 now. Thanks for Bill Boebel for noticing "DELETE .." doing weird things with maildir.

[Dovecot] Subfolder in Maildir
by Bart Braem 29 May '06

29 May '06

Hello, We have installed a brand new Dovecot because it seems very interesting as an IMAP server. We created a mailbox for a test user and we succeeded in copying some mails into it. However making subfolders does not work. The only folders we can create are in the root, next to the INBOX that is. We thought Maildir does support subfolders (as opposed to mbox), are we wrong here? Our Dovecot version is 1.0.b8_1. Bart

[Dovecot] [RFC] create_dovecot_shares
by Gavin Henry 26 May '06

26 May '06

Dear All, As mentioned previously at: http://www.dovecot.org/list/dovecot/2006-May/013003.html create_dovecot_shares is now finished. Apologies to all for the time it has taken. Description: "Creating lots of dovecot-shared files, changing permissions and creating symlinks is a pain, especially when dealing with more than a handle of users. create_dovecot_shares helps. It modifies users home directories and Maildirs (permissions) for sharing via Dovecot, and creates symlinks into the Maildir you want the shares accessed from. There's even a restore option, to roll back any changes you made with a history of 10 runs." Uploaded to my CPAN directory (not indexed yet): http://search.cpan.org/~ghenry/ HTML Docs (embedded in program): http://www.suretecsystems.com/our_docs/create_dovecot_shares.html Syntax highlighted Code: http://www.suretecsystems.com/our_docs/create_dovecot_shares-code.html Actual Program (Please go to CPAN for latest version from now on): http://www.perl.me.uk/create_dovecot_shares Hope this helps someone out.

[Dovecot] Dovecot Authentication to Windows Domain Controller
by Jagga Soorma 26 May '06

26 May '06

Hey Guys, I am trying to convince my co-workers to move from Exchange 2003 to a unix implementation of sendmai/dovecot. They have a couple of concerns that I am sure can be resolved. First, is there a way for dovecot running on a linux server to authenticate a user to a windows 2003 domain controller? If so, then where can I get information on how to implement and test this feature? Also, do you guys know of any calender software that can be used with this implementation as well? Where users can maybe share their meetings? Any comments or suggestions would be grately appreciated. Thanks in advance, -Jagga

[Dovecot] Missing Mailboxes
by Jim 25 May '06

I upgraded from Fedora 4 to 5, which took me from dovecot .99 to 1.x. When I started up Thunderbird, I could not see any mailboxes other than Inbox. I am using Maildir with postfix. I re-installed .99, and all the mailboxes are back. I looked at the wiki on Missing Mailboxes, but I am not sure what I have to fix, and I do not really want to re-install the 1.x version and mess around, as I will mess up a number of other people. Clearly, I am not an expert, so if anyone can can help, I will be most appreciative! Jim

[Dovecot] Bug / Problem - Dovecot and Thunderbird
by wc_fbsd＠xxiii.com 25 May '06

25 May '06

Greetings, I've been running Dovecot for a couple years now. Currently 1.0.b8 on FreeBSD i386. I just switched to Mozilla Thunderbird 1.5.0.2 (windows) for an IMAP client, and am having some problems that appear to be at least partially attributable to Dovecot. After configuring the IMAP account, TB fetched the list of folders on the server, but was displaying several folders that had been deleted from the server months ago. When I tried to access or delete the folders from TB, it produced an error message (imap command failed, or something similar.) Some other folders had been moved from the root to sub-folders -- they still showed in the root, but not the sub-folder, thus were inaccessible. I looked all through the client's config files, but couldn't find any reference to them. From a shell on the server, I also verified they did not exist. I discovered they were still referenced in the .subscribe file, and had index files in .imap on the server. I deleted those, restarted the server processes, and refreshed the folders in TB, and the problem was resolved. But required manual intervention on the server. Not sure if this is a bug or just client issue, but since those files are maintained by Dovecot, I'm inclined to say "bug". Disclaimer: I know next to nothing about the internals of IMAP! -Thanks, Wayne

[Dovecot] LDAP, sieve, and virtual users
by Tracy R Reed 25 May '06

25 May '06

This seems to be a common topic but I haven't seen anyone ask this exact question and get a decent answer: I use virtual mailboxes with all of the db's in LDAP. Last night I upgraded to the latest CVS version of dovecot and dovecot-lda and got global sieve filtering working by setting the global_script_path to a sieve like /home/vmail/mydomain/sieve and it works great. Now I need to figure out how to get per-user sieve filtering to work. I googled on this and found: http://www.dovecot.org/list/dovecot/2005-August/008568.html How do I tell dovecot where the "virtual home directory" is? Yes, I could use /home/vmail/mydomain/user as my virtual home directory (that is where I originally tried to put .dovecot.sieve but it did not seem to work) but I don't see how I can tell dovecot about it. I see that in deliver.c #define SIEVE_SCRIPT_PATH "~/.dovecot.sieve" we hard code SIEVE_SCRIPT_PATH with the home dir location. Am I going to have to replace this with some code that generates an appropriate path for my system or is there a better way? And while I am here: Has any thought been given to being able to pull sieve scripts from LDAP? At the moment sieve really does not buy me much because the end users still do not have any way to edit their sieve files on the server (no shells and can't code sieve's language) but it would be nice if I could create a web interface somewhere which could generate basic filters from templates and store their sieve filters in LDAP so I didn't have to deal with somehow writing to files in their virtual home dirs on the mail server. I have found old conversations such as: http://www.mhonarc.org/archive/html/ietf-mta-filters/1999-06/msg00000.html but do not see where any standard way of doing this has come about. Or really even any implementations at all of sieve stored in LDAP.

[Dovecot] LDA Problem

Hi I'm having a problem with dovecot deliver. I'm using a dovecot version 1.0.beta8. As I am using a chrooted (/var/spool/postfix) postfix (version: 2.2.10) with cyrus-sasl authentification (all working). Postfix config is changed according to the http://wiki.dovecot.org/LDA: main.cf: mailbox_command = dovecot master.cf: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient} I have adopted the dovecot.conf also according to http://wiki.dovecot.org/LDA but changed the auth_socket_path to point into the chroot of postfix. I have attached my dovecot.conf at the end of this email. The mails that are sent to the machine are not delivered at all. In the mail-logfile I can see the following error message for each mail that can't be deliverd: postfix/pipe[21344]: BC254154E5BD: to=<root>, orig_to=<root>, relay=dovecot, delay=0, status=bounced (user unknown) I've already search the net but could not find any clue how to solve this.

[Dovecot] Client workaround?
by David King 24 May '06

24 May '06

I have a phone (LG CU320) with a built-in IMAP client. However, it has some issues. For one, the phone crashes if there are greater than some-as-of-yet-determined-number-of folders. That can't be worked around at the server, but this one can: After a long session of staring at tcpdump, it appears that when it logs in it does so like this: a001 LOGIN "username" myPassword This works unless one has funny characters in their password (which is usually the case). Why on earth it would put quotes around the username and NOT the password is beyond me (which is more likely to have special characters?) It does seem to check the CAPABILITY line to see what authentication is supported, because if I try it with a different (cyrus) server, instead of using LOGIN to authenticate, it uses AUTHENTICATE Dovecot presents that it supports AUTH=PLAIN, whereas Cyrus presents that it supports AUTH=PLAIN AUTH=LOGIN AUTH=CRAM-MD5 AUTH=GSSAPI. This is presumably because Dovecot prefers STARTTLS or simple IMAPS for authentication. So as I see it, getting this phone work with Dovecot and a password with special characters can take one of two forms (either of which I'll be happy to code): 1. Somehow getting Dovecot to look at the second token as if it *were* quoted. 2. Getting Dovecot to present and interpret AUTH=LOGIN (i. e. AUTHENTICATE), which appears to cause the phone to properly escape the password The first one really only fixes certain special characters, and leaves others still broken (like quotes themselves), and in fact violates IMAP4rev1. So I'd just make and run a local patch The second one fixes the problem more cleanly, and my code can be reused and submitted to the Dovecot commiters. So my question to anyone familiar with the codebase is, which of these options is more likely to work, and would the Dovecot team be interested in patches for either one?

But in my experience, it's bad practice, both in the enterprise and in the service provider world.

While some of this statement may be accurate, there's a lot of FUD here too. Both OS X and OS X server use the same kernel, it is true. However, these operating systems are fast and reliable. We ran our mail server for a couple of years on OS X with exim and courier-imap, and the only reason we did stop and move to Linux is because we needed a bigger solution and intel-based hardware was cheaper than a bunch of XServes. And I will challenge your statement about high load. We have two web servers that average betwen 5 and 10 mbits of constant web load, running on OS X Server and XServes. The average load on these boxes is something like 0.20. Roger Weeks

[Dovecot] Busy, again
by Timo Sirainen 24 May '06

24 May '06

Just a note to people if you're wondering why I'm not replying to most of my mails: I'm trying to get into university to start stydying cellular biology (so I'm applying to biochemistry and biotechnology). Their entrance exams are next wednesday, so I'm trying to use most of my time left to study for them (and also do some work..). I don't know much about the subject, so I really need to study for them. :) Then again, if I don't pass, my fallback plan is to go in via computer science and try again next year. Hopefully they allow taking the same bio-classes even if it's not my major.

[Dovecot] Two INBOX locations
by arilinux 24 May '06

24 May '06

Hello I'm running dovecot v1.0.beta3 on a fedora 4 machine. I have two kinds of clients: - first use IMAP and receive their mails (maildir) in /home/%u/mail - second use POP and receive their mails (mbox) in /var/mail/%u Problem is when I want to provide an access for second with squirrelmail which use IMAP, as the INBOX is in /var/mail/%u and IMAP settings tell that INBOX is in /home/%u/mail, they can't view their emails. Is there a way to tell to dovecot to search IMAP mails both in /home/%u/mail and in /var/mail/%u Thanks > Emmanuel RIZZI > ERILOG > 103 rue Beaupoil > 39210 DOMBLANS > Tel: 03 84 44 66 66 > Fax: 03 84 44 62 00 > > >

[Dovecot] Thunderbird 1.5 and messages with no Date: header
by grant beattie 24 May '06

24 May '06

hi, some of my Thunderbird users have a minor but annoying problem with messages that have no Date: header. these clients use BODY[HEADER.FIELDS (Date)] as the date for messages. when a message has no Date: header, they display the date as 01/01/1970 10:00:00 because Dovecot returns empty string. would it be possible for Dovecot to return INTERNALDATE instead, for messages that contain no Date: header? I know this is not *technically* correct, but it's a reasonable best-guess, and better than returning nothing. perhaps as a client-workaround? I vaguely recalled a previous message about this, but I couldn't find it today. grant.

[Dovecot] Shared folder (namespace) access hanging
by Jeff Turner 24 May '06

24 May '06

Hi, I'm using Dovecot 1.0-b8. We use a shared 'support' account for incoming support mail. For security reasons we want to instead have everyone with their own account, accessing a shared 'support' folder. So I've configured dovecot with a public 'Support' namespace: default_mail_env = maildir:/imap/mailboxes/%u namespace private { separator = / prefix = inbox = yes } namespace public { separator = / location = maildir:/imap/mailboxes/support:CONTROL=/imap/mailboxes/%u/shared-settings/support/control prefix = Support/ hidden = no } So now: - User 'support' logs in (this is the user whose folder is being shared). Dovecot creates a dovecot-uidlist file: root@redback:/imap/mailboxes/support/.INBOX.test# cat dovecot-uidlist 1 1147757548 9 1 1147755677.P8078Q3M183587.redback.sydney.atlassian.com:2,RSace 2 1147755677.P8078Q2M183587.redback.sydney.atlassian.com:2,abcdf 3 1147755677.P8078Q1M183587.redback.sydney.atlassian.com:2,Sabcd 4 1147756077.P8078Q8.redback.sydney.atlassian.com:2,Sabcd 5 1147756440.P8461Q3M643698.redback.sydney.atlassian.com:2,Sa 6 1147756440.P8461Q2M643698.redback.sydney.atlassian.com:2,Sa 7 1147756440.P8461Q1M643698.redback.sydney.atlassian.com:2,Sa 8 1147756440.P8461Q0M643698.redback.sydney.atlassian.com:2,Sa root@redback:/imap/mailboxes/support/.INBOX.test# ls -la total 60 drwxrwx--- 5 jturner mail 4096 May 16 15:32 . drwxrwxrwx 59 support mail 4096 May 16 15:31 .. drwxrwx--- 2 jturner mail 4096 May 16 15:18 cur -rw-rw-rw- 1 support mail 448 May 16 15:32 dovecot.index -rw-rw-rw- 1 support mail 21504 May 16 15:32 dovecot.index.cache -rw-rw-rw- 1 support mail 512 May 16 15:32 dovecot.index.log -rw------- 1 support mail 72 May 16 15:28 dovecot-keywords -rw-rw-rw- 1 jturner mail 0 May 16 14:52 dovecot-shared -rw-rw-rw- 1 support mail 516 May 16 15:32 dovecot-uidlist drwxrwx--- 2 jturner mail 4096 May 16 15:01 new drwxrwx--- 2 jturner mail 4096 May 16 15:14 tmp root@redback:/imap/mailboxes/support/.INBOX.test# - If I now log in as 'jturner' and subscribe to this folder, there appears to be nothing in the 'test' folder.

Is anyone actually *using* shared folders? :) Thanks, Jeff

[Dovecot] IMAP Folder Creation
by Zach Hobbs 23 May '06

23 May '06

I am using Maildir with dovecot 0.99.14-1 and postfix. My IMAP server was working where I could create a folder in Kmail or Thunderbird and specify wether the folder was to hold messages or folders. Then something changed, and I lost all my folders that contained sub-folders. And now I cannot create folders that contain subfolders (Kmail doesn't event give the option anymore). I can create folders and put messages in them, but I cannot create subfolders in the newly created folders. The Maildir is owned by the user logging in. Do I need to do anything with permissions, or are there settings to allow/disallow this? I've been reading through everything I could find with dovecot and folders in the message, and I can't come up with anything. Here's an example file structure (logging in as "zta-tech_zach"): Maildir# ls -lA -R .: total 32 drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:41 cur -rw------- 1 zta-tech_zach web1 5 2006-05-22 21:16 .customflags -rw------- 1 zta-tech_zach web1 52 2006-05-22 21:40 dovecot-uidlist drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:16 .INBOX drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:40 new -rw------- 1 zta-tech_zach web1 6 2006-05-22 21:41 .subscriptions drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:40 tmp drwx------ 5 zta-tech_zach web1 4096 2006-05-22 21:25 .Trash ./cur: total 20 -rw------- 1 zta-tech_zach web1 16591 2006-05-22 21:40 1148352021.3157_1.www.zta-tech.com:2,S ./.INBOX: total 24 -rw------- 1 zta-tech_zach web1 1608 2006-05-22 21:41 .imap.index -rw------- 1 zta-tech_zach web1 10264 2006-05-22 21:16 .imap.index.data -rw------- 1 zta-tech_zach web1 2576 2006-05-22 21:16 .imap.index.log -rw------- 1 zta-tech_zach web1 1560 2006-05-22 21:16 .imap.index.tree ./new: total 0 ./tmp: total 0 ./.Trash: total 40 drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:24 cur -rw------- 1 zta-tech_zach web1 5 2006-05-22 21:25 .customflags -rw------- 1 zta-tech_zach web1 1608 2006-05-22 21:24 .imap.index -rw------- 1 zta-tech_zach web1 10264 2006-05-22 21:25 .imap.index.data -rw------- 1 zta-tech_zach web1 2576 2006-05-22 21:25 .imap.index.log -rw------- 1 zta-tech_zach web1 1560 2006-05-22 21:25 .imap.index.tree drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:24 new drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:24 tmp ./.Trash/cur: total 0 ./.Trash/new: total 0 ./.Trash/tmp: total 0 Thanks, Zach

[Dovecot] Dovecot IMAP not putting size in maildir filenames
by Bill Boebel 23 May '06

23 May '06

I notice that when you move a message from one maildir folder to another, Dovecot drops the size information ("S=") from the filename. Dovecot also does not add the size info to filenames after it gets it via stat(). Shouldn't Dovecot add the size info to the filename so that "maildirsize" recalculations are fast? Bill

[Dovecot] two concurrent dovecots

Hello, Is it safe to have two concurrent dovecot processes to access the same maildir? I have a stock RHEL version (0.99.11) used by users, but I also want to test 1.0-beta together wth postfix for SASL. Is it safe to access the same maildir concurrently with both dovecots (say, the old one via webmail and the new one via remote client)? Thanks, Alex

[Dovecot] Dovecot/LDAP problem
by Burton Simmons 19 May '06

19 May '06

Dear Dovecot mailing list people - What I'm trying to do is use Postfix (with virtual users) and a POP3 server (we don't want IMAP - don't ask) to work against our new Active Directory servers that will be coming soon. Before we roll anything out we're testing it in the lab. Here's what we've got: x86 server running Red Hat Enterprise Linux 3 Postfix 2.0.16 Dovecot-1.0 Beta7 Windows 2003 server running Active Directory Windows XP client running Outlook Eventually, we'd like the clients to be joined to the AD domain and that's where we'll store ALL the user information. The email will come in on our postfix server (which uses virtual users) and the clients will check it passing their email username and domain password. The catch is that USERS CAN BE ANYWHERE IN THE DIRECTORY. (I apologize for the caps, I wanted to make sure that phrase wasn't glossed over.) So, for instance: > DC=local | >DC=domain | >OU=group1 | | | > CN=user1 | > CN=user2 | >OU=group2 | | | > CN=user3 | > CN=user4 | >OU=group3 | >CN=user5 The path to user1 is therefore CN=user1,OU=group1,DC=domain,DC=local (at least in the AD world.) The path to user3 is CN=user3,OU=group2,DC=domain,DC=local. So to search for users I would think (because this is how Postfix does it) that I could have the search base as DC=domain,DC=local and then have scope = subtree. IT DOESN'T WORK. (Again, caps used for emphasis only.) Here's the meat of the dovecot-ldap.conf file I'm using: hosts = 192.168.x.x dn = cn=Administrator,cn=Users,DC=domain,DC=local dnpass = xxxxx auth_bind = yes ldap_version = 3 base = DC=domain,DC=local scope = subtree user_attrs = sAMAccountName,mail,,,, user_filter = (&(objectClass=organizationalPerson)(sAMAccountName=%u)) pass_filter = (&(objectClass=organizationalPerson)(sAMAccountName=%u)) user_global_uid = 44 user_global_gid = 44 --- Interestingly, if I simply point the base to the actual user's container, it works just fine. The idea works from Postfix, but from dovecot it doesn't actually seem to search the tree. --- Here's some of the output from the log files. dovecot: May 17 15:35:52 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 lip= 192.168.0.199 rip=192.168.0.195 resp=AGp1c2VyAHBhc3N3b3Jk dovecot: May 17 15:35:52 Info: auth(default): ldap(user1, 192.168.0.195): bind search: base=DC=LAB,DC=local filter=(&(objectClass=organizationalPerson)(sAMAccountName=user1)) dovecot: May 17 15:36:52 Info: pop3-login: Disconnected: Inactivity: method=PLAIN, rip= 192.168.90.195, lip=192.168.90.199 dovecot: May 17 15:37:52 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=192.168.0.199 rip=192.168.0.195 resp=AGp1c2VyAHBhc3N3b3Jk dovecot: May 17 15:37:52 Info: auth(default): ldap(user1,192.168.0.195): bind search: base=DC=domain,DC=local filter=(&(objectClass=organizationalPerson)(sAMAccountName=user1)) dovecot: May 17 15:37:54 Info: auth(default): client out: OK 1 user=user1 dovecot: May 17 15:37:54 Info: auth(default): client out: OK 1 user=user1 dovecot: May 17 15:37:54 Info: auth(default): master in: REQUEST 1 25233 1 dovecot: May 17 15:37:54 Info: auth(default): ldap(user1,192.168.0.195): base=DC=LAB,DC=local scope=subtree filter=(&(objectClass=organizationalPerson)(sAMAccountName=user1)) fields=sAMAccountName,mail,,,, dovecot: May 17 15:38:52 Info: pop3-login: Disconnected: Inactivity: user=<user1>, method=PLAIN, rip=192.168.0.195, lip=192.168.0.199 Can anybody offer any insight?

[Dovecot] configure change for 1.0.beta8
by Tomi Vainio 19 May '06

19 May '06

Hi, I'm trying to compile dovecot under Solaris 10 with native Mysql support. Couple changes are needed before configure can detect and compile mysql support. Native Solaris Mysql is installed under /usr/sfw directory. Configure can't find libraries and when these are found -R runtime path is needed for linking. Also if library name is given before library path it can't find it. These changes are needed for configure script line 29533 for i in /usr /usr/local /usr/local/mysql /usr/sfw; do line 29548 LIBS="$LIBS -L$MYSQL_LIBDIR -R$MYSQL_LIBDIR" line 29559 LIBS="$LIBS -lmysqlclient" line 29770 SQL_LIBS="$SQL_LIBS -L$MYSQL_LIBDIR -R$MYSQL_LIBDIR" line 29780 LIBS="$LIBS -lmysqlclient" Tomppa

[Dovecot] Outlook Express / POP Problem?
by Marc Perkel 19 May '06

19 May '06

I have a new user who is using Outlook Express with POP and seems to be having a problem downloading messages with attachments. Watching the logs it starts to download and then disconnects. When I use squirrelmail which is IMAP it all looks good so it's not a corrupt mailbox. I'm running Beta8 and using MBOX files. The problem seems to be related to POP and/or Outlook. Has anyone run into this before?

I don't think this is the correct fix below, but it did the trick in our environment when maildir_copy_with_hardlinks=yes.

[Dovecot] maildir-tags
by Marten Lehmann 18 May '06

18 May '06

Hello, I configured my MTA to store messages in maildirs with a tag "S=$message_size", so quota calculations can be done without stat()ing the message file. However, I have a lot old messages, than haven't been stored with this tag. Is it possible to configure dovecot so that it will rename each file adding this messagesize-tag if it is not found in a file already? You can find more on this at http://www.exim.org/exim-html-4.62/doc/html/spec_html/ch26.html#id2634917 Regards Marten

[Dovecot] Authentication Daemons
by Scott Penrose 16 May '06

16 May '06

Hi ho. My name is Scott Penrose - and I am experimenting with Dovecot as an IMAP replacement in our company. I have spent some time trying to write a plugin (sort of) for authentication and come to the conclusion that our instance is a little strange. So I though I would try plan B which is to write my own authentication module. This seems to have worked fairly well to start with but I have had some problems. For example, when connecting with a simple socket client (I have a socket client equiv of telnet) I see the VERSION, MECH ... DONE from the login/default socket, but nothing from the master socket. Both should be returning VERSION. Any ideas on that one? Thanks Scott

[Dovecot] Dovecot + Sendmail + virtusertable
by Chris Tata 16 May '06

16 May '06

Hello, I was wondering if there was a way to have dovecot authenticate using sendmail's virtusertable to map virtual users to system users. My goal is to allow virtual users (bob(a)domain.com) to authenticate via pop or imap using the full user@domain scheme. I tried enabling 'vpopmail' as passdb and userdb in the default namespace but I get this error: dovecot: May 15 23:05:21 Error: auth(default): Unknown passdb type 'vpopmail' Please advise. Thanks, Chris

[Dovecot] Missing mails after folder renaming
by Bob & Sabine von Knobloch 15 May '06

15 May '06

Dear List, I seem to have created myself a problem to which I can't find an answer. I am using Dovecot (0.99.13-4.FC2 on Fedora Core 2) with Mozilla Thunderbird on Windows XP and Linux as IMAP client software. I renamed a folder to a name that included spaces (it fitted the pupose better), then later realised that I would have to change my procmail rules to suit. As I wasn't sure what procmail would do with such folder names I renamed the folder back to it's original short name (all this changing was done in Thunderbird). The result is that all subfolders under the renamed folder exist in both forms: eg "Computer.SubjectA" and "Computer Projects.SubjectA", but the second versions are not seen by Thunderbird although they contain all my old mails (new mails are correctly delivered to the short name folders). I have tried to move the mails in these folders back to the short name folders but the indexing system (I assume) does not 'see' these maildir files. How can I fool the system into seeing all the old mails? Of course, I would like to know why the second renaming didn't work but don't have enough information to know if it's Thunderbird or Dovecot that isn't working correctly. As a second question, my Windows clients run in an NT domain (Samba) with roaming user profiles. The pathnames for some users become quite long and Windows throws a 'path too long' error when saving/loading the user profile from the DC. Is there a way of limiting the depth of folder nesting under Dovecot to avoid this problem? I have tried to search for answers but haven't found any yet. If there is already some information, I would be glad of a pointer to it. I am very pleased with the performance of Dovecot in all respects, thanks for the program. Bob von Knobloch.

[Dovecot] Anyone using Dovecot LDA on OS X?

I'm curious if anyone can get the LDA running on OS X, and what their experiences have been... We are still having index corruption issues that result in many temp files being created and client-side timeouts using a straight Postfix local delivery under 1.0beta7. The LDA does not come packaged with the Darwinports version of Dovecot, so any tips on compiling it would be most appreciated... Thanks, -deano

[Dovecot] dovecot ldap auth bind and different directories
by Andrew Bates 15 May '06

15 May '06

I have recently begun playing with Dovecot (1.0.beta8) and have run into an interesting scenario. The way my email system is set up is that users of different domains have completely different base dn's. For instance, if a user is part of test.com the bind dn would be uid=user,ou=People,dc=test,dc=com. The bind dn for user(a)domain.com would be uid=user,ou=People,dc=domain,dc=com. I could not seem to figure out a way to have the binddn adjusted based on a user's @domain so I modified auth-request.c and var-expand.c to include a new variable expansion concept. In the configuration I'm now able to include the following: auth_bind_userdn = uid=%n,ou=People,dc=%c2,dc=%c1 and %c1 will be expanded to the tld, %c2 will be expanded to the next level domain (domain or test in the above example). This will work up to 9 levels of subdomain (1-9). This is very similar in how postfix expands variables with ldap. I'm a bit rusty with my C, so I'd love some feedback on the patch. If this idea isn't included in the main code, that's fine, but I thought I'd contribute my experiences! Thanks for a great product everyone!

[Dovecot] re: ssl-build-param
by Jackie Hunt 15 May '06

15 May '06

Hi all, I posted a message last week about a problem with ssl-build-param, shown below. I may have a lead on this, and was hoping someone can confirm my theory. On AIX, a malloc of 0 bytes returns NULL, which is different than on Solaris and HP-UX (and probably Linux?) I'm guessing the NULL pointer returned is causing the abort of the ssl-build-param, since that was an unexpected result. Looking briefly at the code in ssl-init-openssl.c that seems reasonable. Can anyone please confirm this? And if so, any suggestions on the best way to proceed?

[Dovecot] dovecot and vmailmgr
by Mij 15 May '06

15 May '06

hello now that dovecot supports authentication with checkpassword-compatible modules, I tried to get it working for IMAP on a qmail + vmailmgr server. For a subtle detail, while claiming to be "a drop-in replacement for the standard checkpassword", checkvpw (auth module for vmailmgr) is not "drop in". It actually expects 2 args on its command line, not 1. So, a wrapper is needed to get it authenticating correctly with dovecot; a very simple one (argswrapper.c below). This wrapper is not sufficient though. In fact, vmailmgr represents user homes like this: $HOME_LOCUSER/users/virtual_username this is ok with default_mail_env = maildir:%h/users/%n $HOME_LOCUSER depends on the domain part of the user's email. The relation is held in /var/qmail/control/virtualdomains . However, on the local part (virtual_username) some rewriting is done on the username, as dots are replaced by ":". So in the end j.doe(a)foo.com becomes "~mxfoocom/users/j:doe". Now, var-expand does not support any rewriting. I patched it by adding another modifier, m_str_replace(), which replaces REPLACE_SOURCE with REPLACE_TARGET in a given string. By defining REPLACE_SOURCE to '.' and REPLACE_TARGET to ':' one accomplishes the vmailmgr username rewriting. This modifier is applied with "P", so: default_mail_env = maildir:%h/users/%Pn A better, general solution would be for dovecot to implement some kind of general rewriting, say with regexps and sed-like replacement rules, or with an external process in a cgi fashion. With this patch, dovecot gets the correct path for any user mailbox. However, there's a bug in dovecot storage modules (both maildir and mbox) which truncates the path in the first ":", when expecting ":INBOX" etc specifiers: /* <Maildir> [:INBOX=<dir>] [:INDEX=<dir>] [:CONTROL=<dir>] */ if (debug) i_info("maildir: data=%s", data); p = strchr(data, ':'); if (p == NULL) root_dir = data; else { root_dir = t_strdup_until(data, p); this way, a former data = /var/maildirs/foo/users/j:doe:INDEX=... is truncated to /var/maildirs/foo/users/j . This opens the much worse possibility for user "j:doe" to be accounted into user "j" account after authentication. It is difficult to get a solid fix here, because the grammar is ambiguous for INBOX, INDEX and CONTROL tokens. Since they are not separated with an illegal path symbol from the rest of the path in default_mail_env, it is not possible to state when a ":INBOX=" token belongs to the path and when it is a user directive. The Best is to move the specifiers into a different configuration directive. However, a more solid check with the current modus operandi is /* <Maildir> [:INBOX=<dir>] [:INDEX=<dir>] [:CONTROL=<dir>] */ if (debug) i_info("maildir: data=%s", data); /* extracting INBOX / INDEX / CONTROL suffices */ if (((p = strstr(data, ":INBOX=")) != NULL) || ((p = strstr(data, ":INDEX=")) != NULL) || ((p = strstr(data, ":CONTROL=")) != NULL)) { root_dir = t_strdup_until(data, p); which expects the full ":INBOX=" etc strings to be present in data instead of the single ":" separator. The patches that implement this for both {maildir,mailbox}-storage are also appended below. I will take a couple of hours tomorrow to wrap all the iter up on a web page here http://mij.oltrelinux.com/net/dovecot-qmail-vmailmgr/ All the patches are applied wrt 1.0-beta7 bye

[Dovecot] more unexpected results from 0.99.13 -> 1.0beta8 upgrade

I followed the guidelines in the wiki [1] with regards to upgrading from 0.99 to 1.0, made sure the .subscriptions and .customflags files were renamed to subscriptions and dovecot-keywords respectively yet the subscriptions were not maintained (i.e. users had to re-subscribe after the update) here's my config information, can you give me any hints as to what went wrong?

[Dovecot] Semi-OT: Backing up maildir
by Shayne Hardesty 15 May '06

15 May '06

We switched our mail server over from mbox to maildir a few months ago and couldn't be happier - the performance under normal load is incredible. However we now have a problem with backup.. Typically we would run tar on the mail server, sending its output to another server via ssh.. Like this: tar cfp - /home | gzip | ssh other.server (cd /backups && tar xfp -).. I have tried gzipping the stream on the source side, gzipping on the destination, and running without gzip, all three take an amazingly long time to complete (> 14 hours). Ours is a modest server with about 1300 users, about 300GB of mail total. The whole thing sits on hardware RAID-10, so I'm primarily guarding against a MAJOR hardware failure, a config blunder, or a hacker wiping out files. How do you guys back up your maildir? I've considered exporing the maildir with NFS and backing it up from another server.. Any opinions on that? Thanks, Shayne

[Dovecot] 1.0beta8 won't start: Fatal: Protocol imaps given more than once
by Mike Brudenell 15 May '06

15 May '06

Greetings - I've just built Dovecot 1.0beta8 and find it refuses to start. This under Solaris 10 on an Intel-based Sun system. The error message Dovecot displays (on standard error) in response to /usr/local/sbin/dovecot is Fatal: Protocol imaps given more than once I've checked through my configuration file and the only mention of "imaps" is here: # Protocols we want to be serving: # imap imaps pop3 pop3s protocols = imap imaps The same settings file worked OK with 1.0beta7. I've also tried using the standard dovecot-example.conf that comes with 1.0beta8 which has the "protocols" line commented out and, after adding appropriate settings for "ssl_cert_file" and "ssl_key_file", still have the same problem. I popped a few dubugging i_info() calls into src/master/main.c to try and see what was going on and the output was as follows: Info: set->protocols = >imap imaps< Info: imap: *fd = -1 Info: imaps: *fd = 0 Fatal: Protocol imaps given more than once The first line is displaying the value of the keywords in set->protocols The second and third are within the if/then/else sequence: the first for the "imap" keyword and the second for the "imaps" keyword. Then comes the fatal error, caused by the "fd" variable not being equal to -1 (it is "0" for "imaps") above. Changing the dovecot.conf file to read protocols = imap lets Dovecot start up OK. Changing it to protcols = imaps causes it to fail in the same way as before(!). Seems to be a problem with the initialisation of set->ssl_listen_fd therefore, as this should apparently be -1? Is this likely to be something I've got wrong (wouldn't have thought so as 1.0beta7 is happy with the same config file) or is there a problem in 1.0beta8?

Will dovecot always be open FREE source for all? I am currently migrating my www.digipanel.com from Courier to dovecot as I think courier is overly complicated and a pain in the arse to manage all those files. anyways, I have dovecot IMAP working with MySQL auth but reading the Maildir each time takes up to 30 secs to complete. ANy ideas why? Maybe a dns resolve issue? how can I fix..

[Dovecot] problems with 1.0beta[78] on RHEL3
by alan premselaar 14 May '06

14 May '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've been running 0.99.13 on RHEL 3 for over a year now and finally decided to upgrade to the 1.0 series. unfortunately, I only have one RHEL 3 machine which is my production machine. So, while doing all my preliminary testing I was doing so on a FC 3 machine. I got everything to a stage where I felt comfortable doing the upgrade but I'm running into some problems on the RHEL 3 system. if I download the tarball, it compiles without problem. If I download the cvs or the src.rpm then I get autoconf errors complaining about not supporting AC_CONFIG_HEADER but requiring AM_CONFIG_HEADER. it also complains that the installed version of autoconf is too old, although it's the latest package for RHEL 3 (which means it has the same version number as the original installed package but all the updates are back-ported to it, right?) anyways, that's all trivial as the source compiles. the problem I'm running into is this: the quota plugin is returning the following errors in the mail log: May 13 02:02:13 mail dovecot: POP3(real_user): dlopen(/usr/lib/dovecot/pop3/lib01_quota_plugin.so) failed: /usr/lib/dovecot/pop3/lib01_quota_plugin.so: undefined symbol: mount point_get and also: May 13 02:03:03 mail dovecot: IMAP(real_user): quotactl(Q_GETQUOTA, /dev/sdb1) failed: Invalid argument can anyone offer any assistance with this? oh yeah, one last thing. following the wiki, during the upgrade i renamed the .subscription files to subscription in each user's Maildir directory (oh yeah, i'm using maildir format) but, the subscription information wasn't persistant. anything else i need to be aware of related to that? thanks alan -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFEZMCtE2gsBSKjZHQRAjRVAKCPgSxLQzyJ7lrhCYBSxnVeTJixtgCaA8G5 NtAoCZZWpdetBLGQsA0llrU= =K+09 -----END PGP SIGNATURE-----

[Dovecot] LDA Sieve feature request

Hello, In http://wiki.dovecot.org/LDA I read # If there is no user-specific Sieve-script, global Sieve script is # executed if set. #global_script_path = so you can set global_script_path and override it using a per user script. It would be nice if the per user scripts could be optionally run after (or before maybe?) the global script. Another nice thing would be per-virtualdomain sieve scripts, but I think this is much more difficult.

[Dovecot] 1.0.beta8 released
by Timo Sirainen 12 May '06

12 May '06

Next release will probably be called 1.0.rc1. People just don't seem to like the beta name in the version number. :) Also I think we're nearing the final v1.0. * Fixed a security hole with mbox: "1 LIST .. *" command could list all directories and files under the mbox root directory, so if your mails were stored in eg. /var/mail/%u/ directory, the command would list everything under /var/mail. + Unless nfs_check=no or mmap_disable=yes, check for the first login if the user's index directory exists in NFS mount. If so, refuse to run. This is done only on first login to avoid constant extra overhead. + If we have plugins set and imap_capability unset, figure out the IMAP capabilities automatically by running imap binary at startup. The generated capability list isn't updated until Dovecot is restarted completely, so if you add or remove IMAP plugins you should restart. If you have problems related to this, set imap_capabilities setting manually to work around it. + Added auth_username_format setting - pop3_lock_session setting wasn't really working - Lots of fixes related to quota handling. It's still not working perfectly though. - Lots of index handling fixes, especially with mmap_disable=yes - Maildir: saving mails could have sometimes caused "Append with UID n, but next_uid = m" errors - flock() locking never timeouted because ignoring SIGALRM caused the system call just to be restarted when SIGALRM occurred (probably not with all OSes though?) - kqueue: Fixed "Unrecognized event".

[Dovecot] dovecot-lda and sieve filtering (SMTP is Postfix)
by Der Olli 12 May '06

12 May '06

Hello list. I've got a working Dovecot with Postfix and MySQL-support but everything from the capabilities of sieve isn't working except one thing: Sorting emails to folders works fine. But no vacation, no reject, no redirect. I don't get any errors in the logs. Verbose logging is enabled. I compiled both from newest cvs-sources but also tried older combinations (nightly snapshots). Always the same result and there's no .dovecot.sieve.err so script is okay. If it is not, .dovecot.sieve.err will be generated. I've tested this :) Anyone here who has a working sieve implementation with dovecot-lda? Where do I have to search? Is it a configuration problem? Where can I configure which sending mechanism dovecot-lda should use? Is it a local sendmail binary? Where does dovecot-lda search for it. Is it a SMTP-server? So there's one on port 25 at the local machine. Greetz, Olli

[Dovecot] comment on dovecot documentation on PAM
by president＠irithm.com 12 May '06

12 May '06

Dear Dovecote devotees, I have been going through dovecot configuration for the first time. I am not an experienced systems administrator so I had to do a left turn to read up about PAM while doing all the configuration for my new webmail service. I found that the writing in the dovecot documentation about PAM to be rather misleading in at least one aspect. The documentation I am specifically referring to is at http://wiki.dovecot.org/Authentication?highlight=%28authentication%29 and in the comments found in the dovecot.conf file. In this documentation PAM is referred to as a password database. It appears that is not correct, rather PAM is something that uses a password database. Since the default for "auth_passdb" given in dovecot.conf was "pam" I spent sometime trying to find a pam password database. I eventually found out at an independent website that what pam uses is either /etc/passwd or /etc/shadow or /etc/samba/smbpasswd. It was a relief to find out pam uses one of these, since my system has one of them (/etc/shadow), but I was looking to find something quite different for pam since /etc/shadow is one of the listed alternative values for "auth_passdb". I would have been spared a somewhat lengthy search to find out this information if the documentation was written rather more clearly. So, to help others, I suggest changing the following lines in dovecot.conf # Where password database is kept: # passwd: /etc/passwd or similiar, using getpwnam() # shadow: /etc/shadow or similiar, using getspnam() # pam [<service> | *]: PAM authentication to: # Where password database is kept: # passwd: /etc/passwd or similiar, using getpwnam() # shadow: /etc/shadow or similiar, using getspnam() # pam [<service> | *]: /etc/shadow or similiar, using PAM authentication Updating the documentation in http://wiki.dovecot.org/Authentication?highlight=%28authentication%29 to include a phrase that mentions that PAM authentication works from one of the standard password databases (i.e. /etc/passwd, /etc/shadow or /etc/samba/smbpasswd) would also be helpful. yours sincerely, Rolf

[Dovecot] mandatory client certificates and crl check in ssl-proxy-openssl.c
by HenkJan Wolthuis 11 May '06

11 May '06

hello, I made a modification to ssl-proxy-openssl.c (patch attached) zo that it a) disconnects when no client certificate is presented b) checks the client certificate against the crl for our root cert. (so you can't use a revoked client cert.) c) returns the CommonName from the client cert. in ssl_proxy_get_peer_name (this way it's easier to use dovecot as imap-proxy with a passwd-like userdb, ssl_require_client_cert and ssl_username_from_cert, it "binds" the emailuser to the clientcertificate, a clientcert. can access only the account from the userdb) in order to use it, the CAfile must be a file which contains the CAcertificate (pem format) followed by the CRL (also in pem format). (servercert and the clientcerts are signed with a self-signed rootcert) there are some issues with the patch: a) it needs openssl > 0.9.7 for the CRL checking b) ssl_verify_client_cert now returns 0 in case of an invalid cert. was there a reason why it always returned 1? c) i'm not too happy with the commonname extraction code, is it secure?? d) i've no experience with programming openssl or dovecot e) i haven't programmed in C for at least 8 years...... does anyone here have more issues, corrections, comments on the patch? can/should this functionality be implemented in dovecot?

[Dovecot] "QUOTA" CAPABILITY keyword advertised incorrectly?
by Mike Brudenell 11 May '06

11 May '06

Greetings - I'm having a frustrating time with mail clients not picking up Dovecot's QUOTA extension to IMAP. The problem is that the QUOTA keyword isn't advertised in Dovecot's response to a CAPABILITY enquiry until *after* the user has authenticated. Unfortunately I've yet to find a mail client that issues a CAPABILITY request after authenticating. Instead all do so upon initial connection to the IMAP server (and, correctly, again after subsequently initiating a STARTTLS session but before authentication). Not re-querying the CAPABILITY after authentication is correct according to the IMAP spec in RFC2060, which says: 6.1.1. CAPABILITY Command Arguments: none Responses: REQUIRED untagged response: CAPABILITY Result: OK - capability completed BAD - command unknown or arguments invalid The CAPABILITY command requests a listing of capabilities that the server supports. The server MUST send a single untagged CAPABILITY response with "IMAP4rev1" as one of the listed capabilities before the (tagged) OK response. This listing of capabilities is not dependent upon connection state or user. It is therefore not necessary to issue a CAPABILITY command more than once in a connection. In particular the last two sentences are relevant. (At present Dovecot is only advertising availability of the QUOTA extension *after* authentication, and hence *is* dependent on the user.) Ths means that at present Dovecot's provision of the QUOTA extension isn't actually getting used by popular mail clients such as Thunderbird.

[Dovecot] Fix for the kevent "Unrecognized event" problem.

[Dovecot] IMAP threading - the THREAD command
by Jan Kundrát 11 May '06

11 May '06

Hi folks, there's an extension [1] to IMAP specifying the THREAD command to return list of message sequence numbers grouped to indicate the threading of them. That draft currently defines two algorithms, one of them based solely on Subjects (which is rather dumb) and the second one, combining Subjects with In-Reply-To (etc) headers. The second method is actually advertised and supported by Dovecot. However, I've got quite a lot of friends that lack the knowledge of what the "Subject" field is for, so they just leave it empty. The problem comes when I want Dovecot to return the threads - it follows the ietf draft, so it doesn't check only for references from message headers, but also the subjects. The result is that especially those mails with empty subjects are incorrectly grouped together. So, I'd like to see a feature that would eliminate this problem. It seems to me that there are currently two methods: a) Don't look at the Subject field at all - altough it might increase the speead a bit, it has some disadvantages as well, namely that you'll lose threading if someone uses broken mail client (but broken only in such a way that it preserves subjects) b) Ignore the Subject field if it is empty (after stripping stuff like "re:" etc - just as that draft specifies). Seems reasonable, IMHO. Of course we can't modify the result of a THREAD command (that would break the standard and it generally isn't a proper way to go), so we'd have to introduce another one. I'm pretty sure that especially method a) is very simple (and even simpler if I decided to break the standard by "fixing" the THREAD command), but I really don't like <rant>portable assembler :)</rant> <politely>C</politely>, so are there any chances for this "new and fixed" command to be included into Dovecot? I mean, I might do that in a flawed and ugly way just for me and post a patch so that possible interested persons can pick it, or I migth persuade someone to do it, actually :). Do you think that it's worth the issue? Does anyone have any experiences with talking to the IETF about possible extension of their draft? Ideas?

[Dovecot] Large folders and timeouts
by Fran Fabrizio 11 May '06

11 May '06

I have been having persistent issues with server timeouts on operations on large folders on our Dovecot install (1.0beta2 RPM that came with Fedora Core 5). Some observations from today... I have a Maildir folder with 38,000 messages (it is my Spam folder, naturally :-). In Thunderbird 1.5.0.2, if I click on that folder, it slowly but steadily downloads the headers and after 3-4 minutes, shows me the contents. So far, so good. If I then select all the messages and click Delete to delete them, that operation times out after about 1 minute. If I then click on my Trash folder after some number of minutes has passed, I see that those messages are now both in my Trash and in the original folder - I believe this is because Thunderbird first asks for a COPY over to Trash, and then asks for a STORE +FLAG \\Deleted on the copy that is still in the original folder. It appears that the COPY commands are working but the STORE commands are not since the connection is timing out before they run. I thought I'd try on another mail client, so I tried Squirrelmail. I set it to show 1000 messages per page. It does this just fine. Then I set it to 4,000 messages per page. Then I click on a folder with 12,000 messages, and I get this: ERROR: Connection dropped by IMAP server. Query: SORT (ARRIVAL) ISO-8859-1 ALL My questions are 1. what is the likely cause? and 2. will upgrading to a newer beta address any of this? I'd prefer to wait until FC5 has an updated RPM if possible. Our mail is stored on an NFS store. (I know NFS is slow and that this might be part of the cause.) However, it seems that the timeouts I am having are more related to times when there is no data flowing between the server and client. Note that the timeouts happened when the server was doing a COPY and when the server was doing a SORT but not when the client was downloading 38,000 headers. I'm just at a loss for what to look into next. I don't want to just say "NFS is slow" and live with it if this really has some other cause. :-) So, anyone have any thoughts as to other possible causes? Thunderbird has no option for setting the length of timeout from the client side, so there's nothing I can do from that end.

[Dovecot] Sieve-Editor
by Andreas Martin 11 May '06

11 May '06

Hi all. I'm looking for an editor for sieve-scripts. I tried the Squirrelmail plugin "avelsieve", but it requires "timsieved", wich Dovecot doesn't use. I don't want my users to write sieve-scripts on the console and server-side-filtering is absolutely required. I know that there are some frontends available, but I can't figure out, which one really works with libsieve and is usable for non-geeks... Do you have any suggestions? Thanks, Andreas
