[Dovecot] Make dovecot.index and dovecot.index.cache
by Kenji Iuchi 19 May '10

19 May '10

Hi, I would like to make dovecot.index and dovecot.index.cache manually. But that file is made on connecting IMAP Session. That file contribute to performance improvement, so I want to register myself with crontab. Please teach how to make dovecot.index and dovecot.index.cache manyually. Note. Dovecot LDA is not use. -- /*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/* Kenji Iuchi

[Dovecot] double write-locking dovecot.index.log
by Mike Abbott 19 May '10

19 May '10

Dovecot's transactions often write-lock dovecot.index.log twice (without unlocking in between), and then unlock it twice. Is that intended, or is that a bug? If I read the man pages correctly, double write-locking is pointless but safe. But double unlocking could cause data corruption during the period between the first and second unlocks, because the locks don't nest (are not refcounted). The first unlock leaves the file totally unlocked. Could this be the source of some index corruption errors? For example: 1. Process A acquires a F_WRLCK on a file. 2. Through a different code path, process A again acquires a F_WRLCK on the same file. Since these locks don't nest this is essentially a no-op. 3. Process A modifies the file. 4. Process A unlocks the file to undo the lock in step 2. Now the file has no lock on it at all. 5a. Process B locks, modifies, and unlocks the file. 5b. Process A also modifies the file, thinking that it still has a write lock. 6. Process A unlocks the file to undo the lock in step 1, but this is another no-op. Data corruption is possible if steps 5a and 5b conflict, or if 5b uses stale data. Here is a code path in dovecot-1.2.11 which exhibits the above behavior. "Outer" write lock: maildir_transaction_save_commit_pre -> maildir_transaction_save_commit_pre_sync -> maildir_sync_index_begin -> mail_index_sync_begin -> mail_index_sync_begin_to -> mail_index_sync_begin_init -> mail_transaction_log_sync_lock -> mail_transaction_log_lock_head -> mail_transaction_log_file_lock -> mail_index_lock_fd -> file_wait_lock -> file_lock_do "Inner" write lock: maildir_transaction_save_commit_pre -> maildir_sync_index_finish -> mail_index_sync_commit -> mail_index_write -> mail_transaction_log_rotate -> mail_transaction_log_file_create -> mail_transaction_log_file_create2 -> mail_transaction_log_file_lock -> mail_index_lock_fd -> file_wait_lock -> file_lock_do The file being locked is the same, dovecot.index.log. In another case, maildir_sync_index_begin is reached this way (outer lock): mailbox_sync -> mailbox_sync_init -> maildir_storage_sync_init -> maildir_sync_context -> maildir_sync_index_begin -> mail_index_sync_begin -> etc. And maildir_sync_index_finish is reached this way (inner lock): mailbox_sync -> mailbox_sync_init -> maildir_storage_sync_init -> maildir_sync_context -> maildir_sync_index_finish -> etc. Could these lead to data corruption? Please let me know if you need any more information. Thanks.

[Dovecot] how authentication works?
by Mihamina Rakotomandimby 18 May '10

18 May '10

Manao ahoana, Hello, Bonjour, I've read: http://wiki.dovecot.org/Authentication/PasswordSchemes I have a users database with clear plain passwords. Dovecot authenticates users without problems against it. Now, it's time to move to CRYPT scheme. Before that, I would like to know how things happen. He have: - the user, (entering his password in the MUA) - the user's MUA (Thunderbird, Outlook, Squirrelmail,...) - the POP or IMAP server - the users database (mySQL) with username and crypt()'d password How I think the process is: - the user enters his password in a clear way. - the MUA sends the password as the user entered it to the POP or IMAP server - the POP or IMAP server fetches the password from the database - the POP or IMAP server crypt()'s the user entered password - the POP or IMAP server compares crypt()'d ones and gives his response Am I close enough to reality? Too far? Misaotra, Thanks, Merci. -- Architecte Informatique chez Blueline/Gulfsat: Administration Systeme, Recherche & Developpement +261 3456 000 19

[Dovecot] %d is empty in mail_location
by Phil Howard 17 May '10

17 May '10

I have this in dovecot-postfix.conf: mail_location = maildir:/home/mail/dnamesum=%12MLd/dname=%Ld/unamesum=%12MLn/uname=%Ln/mail Yes, it is excessive, but that's just for testing. The pattern I really want is less clear for debugging. In postfix/main.cf I have: mailbox_command = /usr/lib/dovecot/deliver -c /etc/dovecot/dovecot-postfix.conf -a "${RECIPIENT}" I verified through strace that -a "${RECIPIENT}" is in fact getting a full user@domain address. The problem is that %d and %Ld are coming up as empty, and %12MLd is giving me the first 12 hex characters of an md5 of an empty content. It's losing the domain name somewhere. It's in the mail headers and in the -a option. So what else is needed?

Hi, I sent an email a couple of days ago asking about a problem with ACL. The bottom line was, I think, that I'm missing imap_acl plugin. I installed Dovecot 1.0.7 using yum in CentOS 5.4. Do you know where can I get the imap_acl plugin lib? Thanks A

[Dovecot] Setting up a 'rootless' server - user and auth_user cannot be the same
by Jason Ahrens 17 May '10

17 May '10

I am trying to follow http://wiki.dovecot.org/HowTo/Rootless to set up a personal dovecot server that does not use 'root' and does not need to change uids/gids. I'm trying to set it up on a Cygwin personal system. The problem I'm running into though, the directions say to set "user" and "auth_user" to be the same in this setup. However when you do this, Dovecot compains and will refuse to start up. Did I miss something? $ ./dovecot --version 1.2.11 $ ./dovecot -n # 1.2.11: /usr/local/etc/dovecot.conf Error: login_user cyg_server (uid 1005) must not be same as auth_user Fatal: Invalid configuration in /usr/local/etc/dovecot.conf Config trying to use: protocols = imap disable_plaintext_auth = no ssl = no login_chroot = no login_user = cyg_server login_process_size = 0 login_max_processes_count = 5 mail_location = maildir:~/Maildir max_mail_processes = 5 mail_process_size = 0 auth_process_size = 0 auth default { mechanisms = plain passdb passwd-file { args = /usr/local/etc/dovecot.users } userdb passwd { } user = cyg_server }

[Dovecot] sieve spamtest extension

Hello Stephan, First of all, thanks for time you spent implementing this useful extension. I have found some ugly behavior with such config: sieve_extensions = +notify +spamtest sieve_spamtest_status_type = score sieve_spamtest_status_header = X-Spam-Scan-Score: (-?[[:digit:]]+\.[[:digit:]]) sieve_spamtest_max_value = 10 Sieve: require ["fileinto","envelope","imap4flags","spamtest","relational","comparator-i;ascii-numeric"]; # rule:[spam] if anyof (spamtest :value "ge" :comparator "i;ascii-numeric" "6") { fileinto "Spam"; } If X-Spam-Scan-Score have 6-9 digit after dot - the first one ignored, thus X-Spam-Scan-Score: 3.6 -> "ge" skips. #right X-Spam-Scan-Score: 3.8 -> "ge" works. #wrong X-Spam-Scan-Score: 5.9 -> "ge" works. #wrong X-Spam-Scan-Score: 6.0 -> "ge" works. #right X-Spam-Scan-Score: 6.9 -> "ge" works. #right X-Spam-Scan-Score: 7.3 -> "ge" works. #right If the rule modified to (spamtest :value "ge" :comparator "i;ascii-numeric" "6.0") everything works as expected. One more thing - sieve-test. I couldn't test my scripts with it: # sieve-test -x +spamtest -t sieve spam.txt 00000007: SPAMTEST test 00000007: spamtest: extension not configured 00000013: JMPFALSE (false) Performed actions: (none) Implicit keep: * store message in folder: INBOX Info: final result: success

[Dovecot] dovecot from debian lenny-backports does not accept connections

hi, dovecot from the debian lenny backports does not successfully accept incomming imap or imaps connections; when the client connect i can see the clients ip address in an imap-process but the client cannot succesfully connect and retries this several times where an new imap-process is bound until the maximum connections per client is reached; when the client is closed the imap-processes on the server stay opened, even when dovecot will be restarted or stopped - the processes needs to killed manually; --- snip --- 2010-05-14 02:24:42 auth(default): Info: client in: AUTH 1 PLAIN service=imap

[Dovecot] Wiki page(s) to document executable tools?
by William Blunn 14 May '10

14 May '10

Motivated by a desire to know what "doveadm" does: Do we want to be having a page or pages in the Dovecot Wiki which document the executable tools? It might be an idea for each one to say: * What the tool does * How it normally gets invoked (e.g. manually by the administrator, automatically by some other part of Dovecot, automatically by something else) * What parameters it could take and what they would do List of executable tools: (found in Debian dovecot 1.0.15) lib/dovecot/ checkpassword-reply deliver dict dovecot-auth dovecot-config gdbhelper idxview imap imap-login logview managesieve managesieve-login modules pop3 pop3-login rawlog sievec sieved ssl-build-param (found in dovecot 2.0beta5) bin/ doveadm doveconf dsync libexec/dovecot/ anvil auth config dns-client dovecot-lda expire-tool imap-utf7 listview lmtp log maildirlock script ssl-params Regards, Bill

I can also see Dovecot 2.0 builds in there. But they appear to be being made every couple hours, so presumably based on the bleeding edge of the Mercurial repository. It would be kind of handy to have a Debian package of the original 2.0 beta 5 build. Is that lying around anywhere? Regards, Bill

[Dovecot] dovecot 2.0 vs. SELinux
by Michal Hlavinka 14 May '10

14 May '10

Hi, we were modifying old SELinux rules for dovecot 2.0. Everything seems ok, only one report seems odd: "SELinux is preventing /usr/sbin/dovecot "write" access on dovecot.conf." Looking at strace output, dovecot tries to use socket on /etc/dovecot/dovecot.conf which is regular file and no socket: ... geteuid() = 0 getegid() = 0 open("/dev/null", O_WRONLY) = 3 fcntl(3, F_GETFD) = 0 fcntl(3, F_SETFD, FD_CLOEXEC) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/var/run/dovecot/config"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/etc/dovecot/dovecot.conf"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 nanosleep({0, 70000000}, NULL) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/etc/dovecot/dovecot.conf"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 nanosleep({0, 90000000}, NULL) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/etc/dovecot/dovecot.conf"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 nanosleep({0, 80000000}, NULL) = 0 ... (tries to connect 14x) traceback for connect causing this selinux denial is: connect net_connect_unix : lib/network.c #246 net_connect_unix_with_retries : lib/network.c : #255 master_service_open_config : lib-master/master-service-settings.c #157 master_service_settings_read : lib-master/master-service-settings.c #302 master_settings_read : master/main.c main : master/main.c Does anyone know what happens here? Why dovecot tries to use regular file dovecot.conf as socket? There is probably some magic in it (from my pov) which I don't understand. Regards, Michal Hlavinka

[Dovecot] Compressed mail archives
by Will Palmer 14 May '10

14 May '10

Hello, I have recently begun using IMAP to access my mails, and have found that the size of my maildir is quickly getting larger than I had anticipated. Googling around, I've seen a lot of messages related to compressing individual messages in a maildir. However, what I'm really looking for is a solution which will allow multiple messages to be compressed into a single compressed file, while still allowing those messages to be accessed via IMAP. The reasoning behind this is that most of my incoming mail consists of many very-similar messages (for example, it is not unheard of for me to receive 10,000 emails detailing the same error report over a weekend, with the actual "needs to be processed" parts stuck on the end of each message) I'm expecting a simple "no, there's no way to do that", but I wouldn't mind being pleasantly surprised. My question again: Is there any way to keep a bundle of older mails compressed, so that they can enjoy the high compression of being very similar to each-other, while still allowing access via imap? A solution may involve (just throwing out ideas here, which I have no idea how to implement) putting messages older than N days into an MBox file, and either somehow linking my account to that file (so that my account consists of [compressed readonly Mbox]+[live uncompressed Maildir]), or perhaps the first half of that, but accessing archived messages through a separate account. (Not the preferred way, but if it's the only way, I'll do it) But really I don't even know if it's possible to have dovecot support MBox and Maildir simultaneously, nor do I know enough about the MBox format to even know if the IMAP-style "multiple mailboxes" thing is possible in MBox. Please excuse my no-doubt confused terminology and general air of doesn't-know-what-he's-talking-about. The internals of e-mail are generally not my thing, so I'd appreciate any pointing in the right direction which anyone may have to offer. Any ideas?

[Dovecot] Can't get Thunderbird 2 to delete a folder under mdbox (Dovecot 2.0beta5)
by William Blunn 13 May '10

13 May '10

Can't get Thunderbird 2 to delete a folder under mdbox (Dovecot 2.0beta5) I have built Dovecot 2.0 and installed it under "/opt/dovecot2". I have done the minimum configurations necesary to get it to work with SSL, systems users but with a secondary password database, and set up mail location as "mdbox:~/dbox". I had to create the directory "dbox" in the user's home directory to get things working. Using Thunderbird 2, I can happily copy messages into this system and read them out again, and that all works. In the user's "~/dbox" directory, I get a "storage" directory and a file "m.1". I can also create folders, and nested folders, and put messages into those and read them out again, and that all works. If I try to delete a folder through Thunderbird 2, what happen is that the folder gets moved to be under a folder "Trash" (which Thunderbird calls "Deleted"). So if I had a folder "foo" and deleted it, I end up with a folder "Trash/foo" (which Thunderbird calls "Deleted/foo"). Fair enough: Thunderbird is doing a trash can model on folders. I then go to remove the folder foo from "Trash". Thunderbird doesn't complain, and the folder disappears from the folder list. But upon re-starting Thunderbird, we see that the folder "foo" is still there under "Trash". So it seems the folder was never properly deleted. Perhaps this is a bug in Thunderbird 2, but since this is a beta Dovecot with a new storage subsystem, I thought I would suggest that it might be an issue with Dovecot 2.0beta5. Regards, Bill

[Dovecot] Dovecot and POP3
by DJ GRP 13 May '10

13 May '10

Hi all, I run Dovecot 1.2.9, for both IMAP and POP3 access. I was wondering if there is a way to force messages be deleted from server when the user uses POP3, even if she has selected a 'Leave messages on server' option. I was able to do it in the past using Qpopper (--enable-auto-delete option). Thanks
