That is not right, no matter what. >> No, login_processes_count matters. How? If my understanding is correct, you have extra 3 login processes created to cater to new connections. So with only 3 POP3 users, why should so many login processes be spawned? I can understand 10-15. But 100 definitely indicates either the processes are not dying or something else happening on the system which is causing such high number of login processes. The system definitely needs to be checked for some kind of attack, a rogue process running on the system or something else. Regards --Rao

[Dovecot] dovecot-acl-list not honouring owner / permissions that are set on dovecot-shared
by Stuart Rowan 25 Jun '09

25 Jun '09

Hi, I've just upgraded our dovecot installation from 1.0.15 to 1.1.13. This went smoothly and just worked -- thank you very much for writing such a high performance and robust piece of software. However, we have a shared mailbox that people can subscribe to. After upgrading to 1.1.13 ... dovecot tries to create a dovecot-acl-list file in the top level of this ... but it creates it chown'd to the first logged in user with a umask of -rw- --- --- A. -rw------- 1 userA shared 17179 2009-06-25 11:10 /home/imapshared/SharedMaildir/dovecot-acl-list Everyone else who tried to access the shared folder (and hence dovecot tried to read / update the dovecot-acl-list file) caused an error to be logged to the error.log I changed the permissions (once I realised what had gone wrong) to match those on the dovecot-shared file and all was well as everyone can now read/update it. B. -rw-rw---- 1 imapshared shared 17179 2009-06-25 11:19 /home/imapshared/SharedMaildir/dovecot-acl-list -rw-rw---- 1 imapshared shared 0 2008-04-25 13:20 /home/imapshared/SharedMaildir/dovecot-shared Also from time to time the permissions seem to get changed back on dovecot-acl-list inexplicably to those in situation A -- usually following a restart of dovecot but I haven't been able to reproduce this reliably. This seems like a bug to me ... do you agree / is there a sensible work-around? The declaration in dovecot.conf for the shared namespace sets user specific CONTROL and INDEX locations so that users can independently subscribe to folders and mark messages as read on an individual basis. Many thanks, Stu.

That is not right, no matter what. There is definitely some issue. Once the load increases the system will start timing out on POP3 connections or other network connections, such as IMAP, SSH etc. Better check out the system logs, utilization etc. for any abnormal values.

[Dovecot] Lots of pop3-logins

Hello, Doing a "ps aux" on my Slackware box, I have approx 100 PID's of "pop3-login's going on. This is a production mail server, but it is getting VERY low traffic. In fact, only 3 people can "pop3" into it. I've check their e-mail clients, and they are not checking mail any more often than every 5 minutes. This is a new installation and I've had the server up and running since Sunday. If it matters, I'm using Postfix for the MTA and using the Dovecot SASL library to AUTH SMTP. Is this a cause for concern? Why does Dovecot need this many processes? Thanks! Rodman

Hi Timo, Thank you very much for replying! > What does your configuration look like now? v1.1 has different quota > configuration. Is the problem only with deliver, or is imap also not > updating quota? And dovecot -n unfortunately doesn't show > protocol lda {} contents, so could you show them too? And finally, > enable mail_debug=yes and paste its logs when a message is delivered. mail_debug was already enabled, actually. maildirsize is not updated with imap now. If I logged in imap with dovecot 1.0.13, maildirsize was updated. This is not the case anymore with dovecot 1.1.16 ... I am actually realizing something. Do I need to add the "quota" plugin in the "protocol lda {}" section of dovecot.conf?

[Dovecot] Quota_rules ignored
by A. Gideonse 24 Jun '09

24 Jun '09

Today I upgraded to version 1.1.16 of Dovecot (and Sieve), because I wanted to use mailbox quotas. I tried using the instructions on http://wiki.dovecot.org/Quota/1.1 and simular websites for 4 hours now, but it seems that all quota_rules are ignored. Also, whenever I use a '*' in my MySQL query I get the error: 'unknown quota backend'. With the following query the quota from the database is used (if value is not NULL), but the quota_rules are ignored once again: user_query = SELECT maildir AS home, 5000 AS uid, 5000 AS gid, CONCAT('maildir:storage=', quota) AS quota FROM mailbox WHERE username = '%u' Below is my configuration: # 1.1.16: /etc/dovecot/dovecot.conf # OS: Linux 2.6.24-19-virtual i686 Ubuntu 8.04.1 nfs log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/data/vmail/%d/%n mail_debug: yes mmap_disable: yes dotlock_use_excl: no mbox_write_locks: fcntl mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: mechanisms: plain login debug: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir:User quota quota_rule: *:storage=1G quota_rule2: .Trash:storage=100M Any thoughts on how to solve this problem?

[Dovecot] deliver does not update maildirsize
by ftriboix＠falcon-one.com 24 Jun '09

24 Jun '09

Hello, I have installed postfix 2.5.1 + dovecot 1.0.13 + MySQL and it all works perfectly. I use deliver as the local delivery agent and use IMAP only with maildir mailboxes. I am using virtual mailboxes. Now I wanted to introduce quotas, but I can't manage to make them work. Quota information is retreived from MySQL in userdb requests. I have noticed that the maildirsize file is not updated by deliver when a new mail comes in. I don't know if this is correct or not... It is updated though when I log in. But even then mails are still received without any kind of problem while the mailbox is well over the quota. I tried to add a "-v" option to deliver in postfix's master.cf to debug deliver, but it apparently does not like this option. Please find below my postfix and dovecot's configurations. Thank you very much for any help.

Hello, Some users subscribe to several mailing lists which causes them to have the same message several times what they do not want . Today we use procmail as delivery agent to discard duplicate message, we want to migrate to dovecot deliver + sieve I read a previous post about the duplicate messages : http://www.dovecot.org/list/dovecot/2007-March/021085.html But I do not understand if this feature exists and how to activate Some explanations or documentation would be welcome. thank you, -- Jean-Noel Chardron

[Dovecot] dovecot-antispam problem with sa-learn
by maxlosblob＠tiscali.it 24 Jun '09

24 Jun '09

Hi all, I just set up a dovecot+postfix+roundcubemail+spamassassin system with virtual users. These applications work fine, I have a problem with the dovecot-antispam plugin.

[Dovecot] v1.2.rc6 released
by Timo Sirainen 24 Jun '09

24 Jun '09

http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc6.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc6.tar.gz.sig I think it's time to get v1.2.0 released soon. There is apparently still one rare crashing bug in virtual plugin, but unless someone can reproduce the bug I'm not going to delay v1.2.0 because of it. The release plan is: - Release v1.2.rc7 next Friday (assuming there have been some fixes) - Release v1.2.0 the next Monday I'll be giving a Dovecot talk in Berlin on July 2nd, and I really want to have v1.2.0 released by them. So July 1st is the absolute final deadline for v1.2.0. :) Changes since rc5: * imap proxy: Pass through to client unexpected untagged replies from remote server (e.g. alerts). * Solr: Don't use "any" copyfield, it doubles the index size. * mail_location: Allow using ":" characters in dir names by escaping it as "::". - mbox: Don't crash with invalid From_-lines. - IMAP: Don't crash if IDLE command is pipelined after a long-running UID FETCH or UID SEARCH. - ACL / shared mailbox fixes - Some metadata files were incorrectly getting 0666 permissions.

[Dovecot] courier-imap 2 Dovecot Migration
by Odhiambo ワシントン 24 Jun '09

24 Jun '09

I have a question about migration from courier-imap. I have a server running courier-imap which I'd like to change to dovecot. The problem at hand is that there are POP3 users as well as IMAP4 users.Some of the POP3 users have the option to "leave a copy of the message on the server" set in their MuAs. Is it possible to migrate from courier-imap --> Dovecot and not have these people re fetching all their old e-mails all over again? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ "If you have nothing good to say about someone, just shut up!." -- Lucky Dube

[Dovecot] tcp_wrappers
by listmail 23 Jun '09

23 Jun '09

Hi, I've just started using Dovecot (v1.1.14), and I'm noticing a lot of dictionary attacks. I searched through the documentation and the mailing list archives hoping to find support for tcp_wrappers (hosts.deny) support. I did find some suggested patches in the list from last year, but as far as I can tell, there is no support in the released versions. Is this implemented and undocumented, or just unimplemented? I would be surprised to find it unimplemented in such an otherwise sophisticated project. Thanks in advance, --Bill

[Dovecot] A X-Mailbox header?
by Alessandro Ranellucci 23 Jun '09

23 Jun '09

Hi all, I'm waiting for the virtual mailbox feature in order to make a single POP3 access to retrieve messages contained in all my mailbox folders. This is because I use webmail and other IMAP clients but my main workstation uses a POP3-only client. I was wondering if there's a way to keep the name of the folder containing each message while retrieving via POP3. I guess this could be done by dynamically adding a header to messages at retrieval time. Is there a feature for this or a plugin API? Otherwise I was thinking about modifying the messages themselves on the server using a script. However, such a script would need to be run when a IMAP user moves a message to a folder and I believe Dovecot doesn't provide a trigger/hook mechanism. I also don't know if modifying stored messages is allowed since it could break some caching/hashing mechanism. Do you have any idea for this? Thanks in advance and thanks to Timo for the great work! - alessandro.

Dear friends, My intention is to migrate from Courier-Imap Dovecot 4.4.1 to 1.1.16, the problem is that I've noticed that when creating folders using the Courier does not create the file courierimapsubscribed therefore I doubt if this will bring me problems trying to perform the migration script by courier-dovecot-migrate.pl drwx------ 8 vpopmail vchkpw 4096 Jun 18 16:38 . drwx------ 3 vpopmail vchkpw 4096 Jun 18 09:32 .. drwx------ 2 vpopmail vchkpw 4096 Jun 18 16:36 courierimapkeywords -rw-r--r-- 1 vpopmail vchkpw 265566 Jun 18 16:36 courierimapuiddb drwx------ 2 vpopmail vchkpw 593920 Jun 16 10:05 cur drwx------ 2 vpopmail vchkpw 4096 Jun 18 09:32 new drwx------ 6 vpopmail vchkpw 4096 Jun 18 16:38 .Personal drwx------ 6 vpopmail vchkpw 4096 Jun 18 16:38 .RPV drwx------ 2 vpopmail vchkpw 4096 Jun 18 16:41 tmp Please could help me with this problem because I do not have much experience in this type of migration.

[Dovecot] CRAM-MD5 authentication but plain-md5 password storage.
by Richard 22 Jun '09

22 Jun '09

Hi all, Got a question on configuring dovecot, I'm still new at this so I might be doing this all wrong. I want dovecot to authenticate the mail client using CRAM-MD5 so I've setup the config in dovecot.conf: auth default { mechanisms = cram-md5 passdb sql { # Path for SQL configuration file, see doc/dovecot-sql-example.conf args = /etc/dovecot/dovecot-sql.conf } <snipped> } In my dovecot-sql.conf I've setup the password scheme to be: default_pass_scheme = MD5 Somehow this does not work, the error I see in the logfile is: auth-worker(default): password(info(a)richard5.tld,127.0.0.1): Requested CRAM-MD5 scheme, but we have only MD5 Is there a way to get this working or does this feature only works with passwords stored in plain text ? Thanks! Richard

[Dovecot] dedup in dovecot?
by Roy Sigurd Karlsbakk 22 Jun '09

22 Jun '09

Hi all Deduplicating data is not really a new thing, but quite efficient in mail systems where an email with an nMB attachment may be sent to multiple recipients. This might call for deduplicating data. Is there a way to do this, or is it far off? If I understand the system correctly, usually an MTA is calling dovecot on every single message, meaning the message itself won't necessarily be a duplicate in terms of headers (BCCs and so on). Would it be possible to dedup the content in terms of using separate files for the header and content and then deduping this with hard or symbolic links? Sorry if this is an old question, but I couldn't find anything about it. roy -- Roy Sigurd Karlsbakk (+47) 97542685 roy(a)karlsbakk.net http://blogg.karlsbakk.net/ -- I all pedagogikk er det essensielt at pensum presenteres intelligibelt.

[Dovecot] Dovecot v1.2 share user Maildir problems with %%h
by Steffen Kaiser 22 Jun '09

22 Jun '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm using Dovecot v1.2 9133:f65112bd90b3 with attached config and try to share user Maildirs. The ACLs are working. However the %%h gives me head aches, well, the location in general: I've copied the default mail_location and changed its CONTROL and INDEX settings: namespace shared { ... location = maildir:%%h/Maildir:CONTROL=/var/cache/dovecot/%i/control/shared/%%u:INDEX=/var/cache/dovecot/%i/index/shared/%%u } Now the first wows are that: a) IMAP insists to connect to $install_prefix/var/run/dovecot/auth-master instead of /var/run/dovecot/auth-master used by deliver. My workaround was to symlink /var/run/dovecot/ to $install_prefix/var/run/dovecot/ b) This socket needs to be r/w for every user, which is a security risk as mentioned in the conf and the default permission is 0600. For deliver I changed the socket attr to permission 0660 and group=mail; for making %%h work I added mail_access_groups=mail c) The user's mailbox is not found still, because: 2009-06-17 15:04:57 auth(default): Info: master in: USER 1 testusr/INBOX service=internal 2009-06-17 15:04:57 auth(default): Info: auth(?): Invalid username: testusr/INBOX 2009-06-17 15:04:57 auth(default): Info: userdb(?): Username contains disallowed character: 0x2f 2009-06-17 15:04:57 auth(default): Info: master out: NOTFOUND 1 The imap process passes the mailbox to the authentificator, too. Also, it changes the '.' to '/', although rawlog has: select "shared.testusr.INBOX" If I allow "/" as userchar, I get: 2009-06-17 15:43:00 auth(default): Info: ldap(testusr/INBOX): Unknown user 2009-06-17 15:43:00 auth(default): Info: master out: NOTFOUND 1 It reallt requests the data of user "testusr/INBOX". d) If I use location = maildir:/home/%%u/Maildir: instead of %%h/Maildir, things work _except_ that some user's %%h != /home/%%u . ============== Basically I have yet another problem with location in the user-share namespace: Because one can override the default mail_location for each user, I did so for some users. Some of them even do not have the Maildir. That leads to the problem, that I need one shared namespace for each location template. There had been a suggestion of a special user-shared namespace a while back. How about to add the base location in the shared-mailboxes.db? So instead of "1" the value is the base of the shared location, e.g. maildir:/local/testuser or maildir:/home/user/Maildir..., and some %%? token takes the string from there. Because the path is known from the db now, the other problems mentioned above do no longer apply.

That is the problem, fetchmail just forwards it to port 25 (I think) and I need to work out what to put between fetchmail and dovecot in order to get the mail into the correct folders... And I am just going around in circles on this at the moment. Any hint would be appreciated! Thanks, Michael

[Dovecot] auth_cache multiple passwords ?
by Geoffroy Desvernay 22 Jun '09

22 Jun '09

Hi, First, thanks Timo and Stefan for this great IMAP/Sieve implementation... We are using 1.1.16+cmu_sieve/managesieve additions for now (following releases since ~ 1.0.1). We have a specific problem here with auth-cache: We use direct imap/sieve connection from different clients, using LDAP password: everything is fine. The problem appears with our webmail access using a web-SSO system (jasig's CAS), using one-time-tickets as password for imap connections (checked by pam_cas module for now). For a single webmail connection par login, it work, thanks to cache_key using client's IP. But for multiple use of the same login in the webmail, there are more than one 'password' valid at a time… What may be the 'correct' solution: - patching auth-cache.c (auth_cache_lookup function ?) - writing a different login backend ? - ??? Hope I'm clear enough… -- geoffroy desvernay Ecole Centrale de Marseille

[Dovecot] dovecot-acl file questions
by Steffen Kaiser 22 Jun '09

22 Jun '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, playing around with Dovecot's v1.2 ACLs I wondered about some things about the dovecot-acl files: + They are created within the Maildirs, as described in http://wiki.dovecot.org/ACL. But why? Shouldn't they belong to the CONTROL= directories? So it is more compatible with filesystem quota. + They have 0666 permissions, but all other files (e.g. when I create a new mailbox) have 0660 permissions.

[Dovecot] Corrupted index cache file issues (Corrupted physical size)
by Brent Bloxam 22 Jun '09

Hello, I'm running Dovecot 1.1.13 on FreeBSD 7.0-RELEASE and I'm receiving a large number of errors much like the following: dovecot: Jun 08 09:27:04 Error: IMAP(x(a)x.x): Corrupted index cache file /nfs/x.x/x/Maildir/dovecot.index.cache: Corrupted physical size for uid=2284: 5312 != 5217 dovecot: Jun 08 09:27:04 Error: IMAP(x(a)x.x): Corrupted index cache file /nfs/x.x/x/Maildir/dovecot.index.cache: Corrupted physical size for uid=2281: 6992 != 6894 dovecot: Jun 08 09:31:17 Error: IMAP(y(a)y.y): Corrupted index cache file /nfs/y.y/y/Maildir/dovecot.index.cache: Corrupted physical size for uid=9241: 14545 != 14453 dovecot: Jun 08 09:37:05 Error: IMAP(z(a)z.z): Corrupted index cache file /nfs/z.z/z/Maildir/dovecot.index.cache: Corrupted physical size for uid=22741: 12150 != 12066 These are not occurring for all users, but it occurs frequently for the addresses that do show up in the logs. The maildirs are migrated from a previous courier server. I've tried searching the archives and can't find anything related to this error. Could someone shed some light on it? Other than the error messages, I'm not aware of anything being affected, but I'd like to be sure of it Some info about the configuration: Maildirs are accessed via NFS, related settings are mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes lock_method: dotlock Regards, Brent

[Dovecot] dovecot and ntp: Fatal: Time just moved backwards
by Arno Wald 22 Jun '09

22 Jun '09

Hallo, I am running dovecot on a PC (a workstation) to have a mail client independent storage for my mails. Now I would like to have the system clock set correctly by using ntpd or ntpdate (using debian/sid). The problem is, that the PC is not online at boot time, but is set online on demand manually using "pon" to start the pppd later. So ntpd cannot sync the time on boot time before dovecot gets started. First I was using ntpdate that was started in ppp's if.up.d/ directory. This tool does set the time very hard instead of just slightly shifting some milliseconds. So dovecot did stop itself, reporting: "Fatal: Time just moved backwards by 118 seconds. This might cause a lot of problems, so I'll just kill myself now." So I have tried ntpd as I thought it shifts the time in smaller time deltas. But this takes much time (several seconds) when booting, giving up on all configured servers, because they are not reachable when booting (as going online later manually). This turns off ntp functionality because ntpd does think that all servers are unreachable for ever. (I have tried a command "dynamic" in ntp.conf but this did not change anything and ntpd reports it to be obsolete.) My idea now is to not start ntpd on system boot, but only on if-up. But this brings up the same fatal error of dovecot as ntpd seems to hardly set the time, too. The only idea I have left is to stop dovecot, start ntpd and then start dovecot again on if-up. Is there a more elegant way to use dovecot and ntpd on a manually dialed in PC? Thanks, Arno

[Dovecot] cross compiling (arm)
by Stephen Feyrer 21 Jun '09

21 Jun '09

Hi. I'm trying to cross compile dovecot. My desktop machine is an AMD64 box with bells and whistles. The ARM based machine is a network attached storage box. When I run "make" always get x86_64 binaries. My OS is Gentoo, so I have been able to build using emerge a variety of other programs from source. What am I doing wrong here. (Gentoo doesn't have Dovecot for the arm) I run: ./configure --prefix=/opt --target=armv5tel-softfloat-linux-gnueabi host=armv5tel-softfloat-linux-gnueabi --build=x86_64-pc-linux-gnu --cache-file=config.cache These are some values from config.cache which I think are pertinent: ac_cv_build=${ac_cv_build=x86_64-pc-linux-gnu} ac_cv_c_compiler_gnu=${ac_cv_c_compiler_gnu=yes} ac_cv_env_build_alias_set=set ac_cv_env_build_alias_value=x86_64-pc-linux-gnu ac_cv_env_host_alias_set= ac_cv_env_host_alias_value= ac_cv_env_target_alias_set=set ac_cv_env_target_alias_value=armv5tel-softfloat-linux-gnueabi acl_cv_path_LD=${acl_cv_path_LD='/usr/x86_64-pc-linux-gnu/bin/ld -m elf_x86_64'} lt_cv_path_LDCXX=${lt_cv_path_LDCXX='/usr/x86_64-pc-linux-gnu/bin/ld -m elf_x86_64'} lt_cv_sys_lib_dlsearch_path_spec=${lt_cv_sys_lib_dlsearch_path_spec='/lib /usr/lib /usr/local/lib //usr/lib32/opengl/nvidia/lib //usr/lib64/opengl/nvidia/lib /lib /usr/lib /lib64 /usr/lib64 /usr/local/lib64 /lib32 /usr/lib32 /usr/local/lib32 /usr/x86_64-pc-linux-gnu/lib /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2 /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2/32 /usr/lib/gcc/x86_64-pc-linux-gnu/4.2.3 /usr/lib/gcc/x86_64-pc-linux-gnu/4.2.3/32 /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2 /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/32 /usr/lib64/nspr /usr/lib64/nss /usr/lib64/seamonkey /opt/blackdown-jdk-1.4.2.03/jre/lib/amd64/ /opt/blackdown-jdk-1.4.2.03/jre/lib/amd64/native_threads/ /opt/blackdown-jdk-1.4.2.03/jre/lib/amd64/classic/ /opt/blackdown-jdk-1.4.2.03/jre/lib/amd64/server/ /usr/kde/4.1/lib /usr/kde/4.1/lib64 /usr/kde/4.1/lib32 /usr/kde/4.2/lib /usr/kde/4.2/lib64 /usr/kde/4.2/lib32 /usr/lib64/qca1 /usr/lib64/qca2 /usr/lib/qt4 /usr/lib64/qt4 /usr/lib32/qt4 /usr/qt/3/lib /usr/qt/3/lib64 /usr/qt/3/lib32 /usr/games/lib /usr/games/lib64 /usr/games/lib32 /opt/flash-libcompat /usr/lib64/fltk-1.1 /usr/lib32/libstdc++-v3/ '} lt_cv_sys_lib_search_path_spec=${lt_cv_sys_lib_search_path_spec='/usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2 /usr/lib64 /lib64 /usr/x86_64-pc-linux-gnu/lib'}

The first server was startet on Jun 2 and ran until Jun 18 and the other startet on Jun 3 and failed on Jun 15. Both generated then lots of error messages, three for every user that attemps to login, looking like that: Jun 15 08:35:23 minerva dovecot-auth[20831]: [ID 401707 user.error] open_module: /usr/lib/security/pam_unix_account.so.1 failed: ld.so.1: dovecot-auth: fatal: /usr/lib/security/pam_unix_account.so.1: open failed: No such file or directory Jun 15 08:35:23 minerva dovecot-auth[20831]: [ID 487707 user.error] load_modules: can not open module /usr/lib/security/pam_unix_account.so.1 Jun 15 08:35:23 minerva dovecot: [ID 107833 local0.error] auth-worker(default): pam(gp1071,134.176.2.89): pam_acct_mgmt() failed: Dlopen failure The file /usr/lib/security/pam_unix_account.so.1 was still there and had not been changed.

[Dovecot] compiling dovecot-1.2-sieve-0.1.5 with the latest dovecot-1.2.rc5
by Tim Traver 19 Jun '09

19 Jun '09

Hi all, ok, downloaded dovecot-1.2.rc5 and compiled it with no problem. Then, I went to compile the latest dovecot-1.2-sieve-0.1.5 with it, and got the following error : mail-raw.c: In function 'mail_raw_init': mail-raw.c:119: error: 'NAMESPACE_FLAG_INTERNAL' undeclared (first use in this function) mail-raw.c:119: error: (Each undeclared identifier is reported only once mail-raw.c:119: error: for each function it appears in.) *** Error code 1 In looking around, I noticed in a changed log dated last month, that the NAMESPACE_FLAG_INTERNAL was moved to be two separate flags "_NOQUOTA and _NOACL"... But I think that the author of dovecot-1.2-sieve-0.1.5 hasn't made the change to handle that... So, first of all, I guess I would just like to bring it to the authors attention if it hasn't been already, and second, what is the last rc version before that change so I can actually get things to compile? Thanks, Tim.

[Dovecot] quota.
by Mauro 18 Jun '09

18 Jun '09

Hallo. Sorry for may bad english. I'm running dovecot 1.0.15 on a debian lenny system. I've set quota plugin and, under section plugin, I've set: quota = maildir quota_rule = *:storage=50M quota_rule2 = Trash:storage=10%% quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80. For some accounts the quota limit works well. When I send mail I receive a rejected mail for quota exceeded. For some other accounts it doesn'work despite they have passed the 50M storage limit. Why?

[Dovecot] Question about "target is inferior" type of message
by Michael Durket 17 Jun '09

17 Jun '09

We're converting UW-IMAP users here to dovecot. Some of them have seen the error message issued when Thunderbird clients try to delete folders and I understand what's going on (from previous postings) that Dovecot doesn't support mbox subfolders within folders. What puzzles me is that many of these users already have folders within folders (I've found typically 2 levels of nested folders within their main Mail directory). And they're not complaining that they can't read the messages in those folders. If UW-IMAP supposedly never supported this for mbox format, and Dovecot doesn't support it, how is this possible under Dovecot? (We don't have any maildir format mailboxes here at all).

[Dovecot] enourmous amount of disc writes
by Rainer Sigl 17 Jun '09

17 Jun '09

Hi List, on my mailserver (exim4, dovecot 1.0.0, postgresql, ubuntu dapper, about 500 users) I record an enourmous amount of disc writes (up to 18000 blocks written each second) in the time where most of users are active. This IO activity causes wait-states on the disc interface (RAID5) and finally slows down my mailmachine. Is there a explanation for these disc writes respectively is there a possibility to minimize this activity. Stopping Dovecot on this machine causes stopping most of the disc activity.

[Dovecot] v1.2.rc5 imap ignores configuration reloads
by Pascal Volk 16 Jun '09

16 Jun '09

Hi Timo, after changing the mail_executable in the imap {…} section I have to restart Dovecot v1.2.rc5, otherwise the changes are not accepted. With Dovecot v1.1.x (tested with v1.1.11 and v1.1.16) it's enough to send a SIGHUP to the dovecot process. Regards, Pascal -- The trapper recommends today: c01dcofe.0916521(a)localdomain.org

Some ages ago there existed a compressed mbox patch, but now all I can find are posting about it. Does such a beast exist and would it remotely apply to today's dovecot? If not, is there any hope that something like that emerges? Thanks! -- Axel.Thimm at ATrpms.net

I've copying messages automatically to sent folder if it sent via our SMTP. Problem is Deliver can't mark message as read on deliver. Does that possible to accomplish using global sieve rule? I'm not familiar with sieve code syntax, know very basics. Also I know there different implementation in Sieve between 1.0, 1.1 and 1.2. Thanks

[Dovecot] Authentication cache, failure to login after changed password
by Tom Sommer 16 Jun '09

16 Jun '09

Hi, I have an issue with the authentication cache. When a user changes his password, the cache doesn't seem to get flushed. Meaning the user is unable to log in to his IMAP account after changing his password. Flow: - Log into IMAP account using pass1 - Approved - Stored in auth cache - Change password to pass2 in MySQL - Log into IMAP account using pass2 - Access is denied - Restart dovecot - Log into IMAP account using pass2 - Approved I'd really like to continue to use the auth cache, is there any solution to the above? perhaps a way to debug the cache and auth process? I wasn't able to activate auth_debug without restarting Dovecot and solving the problem. Using version 1.1.1, MySQL userdb, with "nopassword=Y". Maybe it's due to nopassword? Thanks -- Tom
