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

24 Oct '06

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

[Dovecot] Creating MySQL db
by Gerard Seibert 24 Oct '06

24 Oct '06

I was just wondering if anyone was using or aware of a program to create MySQL Data Bases for use with Dovecot. For Postfix, there is the 'Postfixadmin' application. I have not seen anything similar for Dovecot and was wondering if one existed. My system consists of all virtual users. -- Gerard Never attribute to malice what can adequately be explained by incompetence.

[Dovecot] problems with authentication
by Paul Aguirre 24 Oct '06

24 Oct '06

Hi, I have some problems I'm using fetchmail to get my mail from the server to a local server, but the problem is that my user name of the mail is "user@virtualdomain" and I can't make a system user with "@" on centos. So, I want to know how can I tell to dovecot the user "user@virtualdomain" is associate to a sistem user "user.virtualdoman". Or if any one knows another solution.

[Dovecot] Proxy using passd file
by Clayton Epp 23 Oct '06

23 Oct '06

I'm trying to create a proxy using passwd files. Can I use the existing passwd files created by the system (ie passwd and shadow) or do I have to create new passwd files for the email proxy users? How would the passwd and shadow files for a proxy using passwd files look? I've tried the example on the wiki but I'm not getting anywhere, pop and imap requests are not getting sent to the other server.

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

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

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

22 Oct '06

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

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

FreeBSD 6.1 STABLE Postfix-2.4-20061006 Dovecot-1.0.rc7 I am using 'saslauthd -a sasldb -c' for authentication with Postfix.

[Dovecot] Virtual Users
by Gerard Seibert 20 Oct '06

20 Oct '06

Dovecot 1.0.rc7 Postfix 2.4-20061006 FreeBSD 6.1 STABLE I have dovecot up and running with postfix. I now want to switch over to a system using purely virtual users. I have gotten postfix configured to deliver the mail to virtual mailboxes correctly. The problem I am having is with dovecot. After configuring the dovecot.conf file, dovecot will POP mail from the virtual mailboxes. However, that is only for users who are in the /etc/password file. I will have a large number of users who are truly virtual and therefore not be in that file. I know I am dumb, but I do not know how to set up either a MySQL data base, or just a plain flat file with the required information. I tried Googling, but I cannot find the exact syntax to use. Perhaps someone could point me in the right direction or give me a brief example of how to go about this. Thanks! -- Gerard "It is not the OS's job to stop you from shooting your foot.

[Dovecot] Problem with indexes
by crs 20 Oct '06

20 Oct '06

Hello. Dovecot is really good software but I have one big problem with indexes. I have server with a lot of mailboxes - filesystem has quota enabled and I can't resign it from different reasons. When mailbox achieve quota size and user wants to pick mails via pop3, error "-ERR Mailbox is in inconsistent state, please relogin." is given. I know it's because dovecot can't write indexes. Is it possible to force dovecot to write indexes with definite owner/group f.e dovecot/dovecot and not owner/group of mailbox? I can set quotas for user dovecot to unlimited and problem would disappear. Thanks in advance for any answers.

[Dovecot] Subscription file
by Steven F Siirila 19 Oct '06

19 Oct '06

Background: We are a UW-IMAP shop, using mbox format. (!) We are in the process of upgrading to Dovecot, hopefully to 1.0 proper. :) One of the modifications we have been using in test versions of Dovecot involve the move of the user subscription file from: IMAP-root/.subscriptions to: $HOME/.mailboxlist Rather than having to make changes to Dovecot source code each time a new release comes out, it would seem to make sense to have a way to configure this from dovecot.conf. Something like: # Default (%i denotes IMAP root): #imap_subscription_file = %i/.subscriptions # UW-imap-style (%h denotes home directory): #imap_subscription_file = %h/.mailboxlist While it makes sense to me to have the subscription file where it is in Dovecot by default, it would be a substantial undertaking to determine where to move the .mailboxlist to in our environment for each user, since there is no easy way to determine what a user's IMAP root directory is set to in their client.

Is there a way to limit the number of folders a user can have open simultaneously?

[Dovecot] Urgent - Inconsistent Inboxes
by Jakob Curdes 19 Oct '06

19 Oct '06

Hi, An urgent problem that I have : runninng dc 0.99.14 w mbox on local ext3 , nothing special, no nfs, nothing. For this machine we have a backup server rsyncing everything over. Now the main server went down and we started DC on the backup machine some day ago. Everything went well, besides one problem : people complained about missing mails that they had seen beforehand. When looking in the inbox, they were all there. After recreating the imap account (outlook express) or deleting the cache file (thunderbird .msf files) everything was well. But you can't really recreate all accounts after switching to the backup machine every time.... today we went back to the main server and in advance I deleted all .imap.index files hoping that they might have been the eventual cause of the problem, but no, same thing happens again. It now seems to me that this is a pure client issue, but nevertheless two questions : a) who knows a way to tell the client (OE or TB in this case) to disregard all local information and get everything fresh from the server ? b) Can this behavior be influenced from the server side? I know I'm behind with 0.99.14 but up to now there was no problem and "never change a running system". If upgrading could help, I would do it immediately. Any hints welcome, especially fast ones as tomorrow morning I have to get the clients running. Yours, Jakob Curdes

[Dovecot] Logging authentication failures?
by dri 19 Oct '06

19 Oct '06

I use a script that watches log files looking for failed ssh login attempts and adds firewall rules when there are enough login failures within a certain amount of time. I would like to apply this to Dovecot to automatically firewall attackers trying to brute-force an IMAP account. Is there a way to make Dovecot log authentication failures (I'm running 1.0.rc10)? In other words, can I configure Dovecot to put something in the log the instant "NO Authentication failed" is sent to the IMAP user? With "auth_verbose = yes" I can see individual authentication mechanisms fail, but I have multiple passdb sections so a failure in one mechanism doesn't mean a complete login failure. Thus, configuring the script to watch for individual mechanism failures may result in the firewalling of legitimate users. Thanks for any info!

[Dovecot] passdb checkpassword and lastauth
by Max A 18 Oct '06

18 Oct '06

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

[Dovecot] 1.0.rc10 released

18 Oct '06

http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz.sig I've finally read all the mails in the mailing list and in my INBOX. If I haven't replied to some of your mail, please resend it. Remember that since 1.0.rc9 release dovecot.index.cache files will get rebuilt in 64bit systems, and it's probably better to delete them manually so you don't get errors in log files. There are only a couple of issues left in my v1.0-TODO list: - Master process appears to be leaking log fds with kqueue. Could someone again give me access to a system where this happens? - Login process problems. How well does it work now? Hopefully well enough that v1.0 could be released. - LDAP authentication is leaking memory? Can anyone confirm this? Even better, can someone figure out what exactly is leaking? :) Not a v1.0 blocker though. I think v1.0 will be released once no-one has reported any major problems for a Dovecot release in 2-4 weeks. I think login process handling is the only potentially major problem left. There are a few patches from people that I haven't forgotten, but I've decided not to put them into v1.0 anymore: - Filesystem quota group. I don't think it's that important feature, and it might break something. - HFS+ hardlink avoiding - Managesieve - vmailmgr support And finally the changes in this release: * When matching allowed_nets IPs, convert IPv6-mapped-IPv4 addresses to actual IPv4 addresses first. + IMAP: Try to avoid sending duplicate/useless message flag updates + Added support for non-plaintext authentication for vpopmail if it returns plaintext passwords. Based on patch by Remi Gacogne. + Added %D modified to return "sub.domain.org" as "sub,dc=domain,dc=org" (for LDAP queries). Patch by Andrey Panin. - rc9 broke cache files in 64bit systems - deliver works now with mail_chroot - auth cache didn't work properly with multiple passdbs - Fixes to handling CRLF linefeeds in mboxes.

[Dovecot] autoconf check for ldap not linking with -lber
by Jorgen Lundman 18 Oct '06

18 Oct '06

Maybe not a big deal, but generally you (used to?) link against both: configure:31276: checking for ldap_init in -lldap configure:31311: gcc -o conftest -std=gnu99 -I/usr/local/include -Wall -W -Wmiss ing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat =2 -Wbad-function-cast -I/usr/sfw/include -L/usr/local/lib conftest.c -lldap -lsocket -lnsl -lrt -lsendfile >&5 Undefined first referenced symbol in file ber_sockbuf_io_readahead /usr/local/lib/libldap.so ber_sockbuf_alloc /usr/local/lib/libldap.so ber_sockbuf_io_fd /usr/local/lib/libldap.so But could be special situation as my LDAP version is fixed, due to production environment using it. It also failed when OpenLDAP was linked against OpenSSL, since it does not try with the SSL libraries.

[Dovecot] defunct processes

[Dovecot] Strange POP3 problem...
by Mike Cisar 18 Oct '06

18 Oct '06

I've been having this problem for a long time now. It started when I first began to use Dovecot (0.9x) and seems to have been occurring more and more frequently as we've progressed through the betas and now into RC7. I have been kind of chaulking it up to a "user issue" since the problem only seems to occur for one user (who has one machine at his office, and one at his weekend cabin... problem occurs with equal frequency on both of his machines). Lately it's been occurring about once every couple of days, but still nothing that I have been able to reproduce with any particular email or frequency. However as luck would have it the problem occurred today while I was onsite at the client's office so I was at least able to see that end of things at the same time. Essentially the user will have a number of messages in their mailbox (today for example 13) the download of mail will go just fine until one particular message and then the download will just stop, eventually returning an error message. Trying to receive mail again will retrieve messages 1-9 again and fail in the same spot. If you log in via IMAP and delete the following message (ie. the message after the one that was last received) you can then POP for mail again and the remaining messages in the mailbox will download. In the log all we see is the following (over and over)... Aug 28 16:14:51 mail dovecot: pop3-login: Login: user=<xxxxx>, method=PLAIN, rip=vvv.www.xxx.yyy, lip=vvv.www.xxx.yyy Aug 28 16:15:32 mail dovecot: POP3(xxxxx): Disconnected top=0/0, retr=9/170375, del=0/13, size=1349520 >From the client side I get the following in Outlook Express... "Your server has unexpectedly terminated the connection..." "...POP3, Server Response: '+OK 795 octets'..." Interestingly 795 bytes is the size of the "bad" email (the one that won't download). Any thoughts? Cheers, >>>>> Mike <<<<<

[Dovecot] Index files
by Steven F Siirila 17 Oct '06

17 Oct '06

I am doing some testing with Dovecot and wondered if it was normal for the deliver program to create index files for an Inbox (the test Inbox is over 7MB), but to not update the index files after the initial creation, even though messages continue to come into the mailbox. Note that during this testing, no IMAP or POP accesses are being made. Would it matter if a command-line program such as mutt were reading/updating the Inbox in question? Shouldn't Dovecot delivery be continually updating the index files as new messages arrive in the Inbox? -- Steven F.

[Dovecot] dovecot tpop3d UIDL mbox
by antencek＠volja.net 17 Oct '06

17 Oct '06

Hello All! I am new to this list so I hope I'm not in the wrong list with my question. First, I have to say that dovecot is (in my opinion) one of the best POP3/IMAP servers arround. I especialy like its' simplicity (configuration) and powerfullness (speed, auth mechs). In my production environment I would like to cange from tpop3d to dovecot, but I have only one little problem :). This is my situation: pop3 server: tpop3d mail fromat: mbox (/var/mail/username) UIDL: tpop3d UIDL format Since there are users who let mail on server, I need to keep UIDL. The problem is that the patch which gives dovecot the capability to replay with tpop3d UIDL format apparently works only on maildir mailboxes. Is there any resonable solution to my problem? TIA. Regards, Antencek

Hi. I want to use allow_nets in my configuration, but i have some troubles which i cant resolve. To use allow_nets i creates `allow_nets` text field in my mysql users table. My query is: from: dovecot/sql.conf: password_query = SELECT crypt as password, maildir as userdb_mail, 6 AS userdb_uid,6 AS userdb_gid, allow_nets FROM users WHERE id = '%u' from dovecot.conf: auth default { mechanisms = plain passdb sql { args = /usr/local/etc/dovecot/sql.conf } userdb prefetch { } user = root } To check this i added address 193.193.193.100/32 (which is not my address) and tried to connect from localhost (using telnet). And it allow me to connect! May be i did something wrong, but i cant explain this, so i`m asking for your help.

The alarming aspect of the corruption is when it occurs at the beginning of an email (i.e. ^@^@^@From:...). Emails can be lost/appended to the bottom of the previous email. I've seen this problem several times on our deployment and tracked it down to what appears to be NFS locking issues. Are you storing mails on an NFS mounted filesystem? If so check the following... http://wiki.dovecot.org/NFS We're running dovecot-1.0 beta5 (admittedly not an rc version but >beta4 which is mentioned in the NFS wiki section) so I'm not sure the mbox rewrite from v0.99.x has fixed the problem. We had several applications accessing the mbox (Dovecot and Pine mainly). Reconfiguring Pine to use IMAP (using Dovecot) rather than write to the mbox directly appears to have fixed the problem and we have had no corruption for several months now. So, my question is am I wrong to assume NFS locking/corruption? Does anyone know if this is really a Dovecot or NFS issue? Phil

[Dovecot] 1.0.rc9 released
by Timo Sirainen 17 Oct '06

17 Oct '06

http://dovecot.org/releases/dovecot-1.0.rc9.tar.gz http://dovecot.org/releases/dovecot-1.0.rc9.tar.gz.sig Most importantly this should fix the login process problems that people have been reporting. There were also some bugs in the proxying feature. Also note the 64bit change in dovecot.index.cache files. Unless you delete dovecot.index.cache files manually, you'll these kind of error messages into your logs: Error: Corrupted index cache file ...dovecot.index.cache: registered field date.sent size changed They'll get fixed automatically of course, but it might be a bit annoying to see them. * 64bit systems: dovecot.index.cache file will be rebuilt because some time fields have been changed from 64bit fields to 32bit fields. Now the same cache file can be used in both 32bit and 64bit systems without it being rebuilt. * Added libmysqlclient workaround to conflicting sha1_result symbol, which caused Dovecot to fail logging into MySQL. + dovecot.index.cache file opening is delayed until it's actually needed. This reduces disk accesses a bit with eg. STATUS commands. + auth_cache: Try to handle changing passwords automatically: If password verification fails, but the last one had succeeded, don't use the cache. This works only with plaintext auth. - dovecot.index.cache: We didn't properly detect if some fields were different length than we expected, which caused assert crashes - Lots of fixes to login/master process handling - mbox: Fixed a bug causing "X-IMAPbase uid-last unexpectedly lost in mbox file" errors, and possibly others.

[Dovecot] Separate auth for pop and imap
by Hr. Daniel Mikkelsen 17 Oct '06

17 Oct '06

Hi. Is it possible to set up separate authentication backends for POP and IMAP for a single Dovecot instance? Or does this require two separate dovecot instances with separate config files? Specifically, I want to have one database query for IMAP and one for POP so that I can let these be separate features that I can flag in a database. -- Daniel Mikkelsen Copyleft Software AS

[Dovecot] MBox path
by Rick 17 Oct '06

17 Oct '06

Hi, I'm having great difficulty pointing Dovecot to my MBox files. They are all in /var/spool/mail/username as textfiles.. not directories. So my guess was: default_mail_env = /var/spool/mail/%u Since %u is user. If the user is "server" I would expect it to go to /var/spool/mail/server exactly what I want. But it doesn't /var/spool/mail///home/server. If I create the directory home in /var/spool/mail and make a symlink of the username pointing to /var/spool/mail it does work. But that's a very dirty workaround I rather not use, also because we have a lot of users.. a lot of symlinks. If I set default_mail_env = /var/spool/mail, it also searches for /var/spool/mail///home/server. I feel like I've tried everything. What am I doing wrong? I'm using version 1.0.beta8, included in Fedora Core 5. Thanks, Rick

[Dovecot] Dovecot still failing with RC10...
by Timothy Meader 16 Oct '06

16 Oct '06

Hello, I mentioned back with version RC8 that dovecot was having an issue with the first login working, but all subsequent attempts failing with the error message: "Error: Maximum number of mail processes exceeded" in the dovecot log file. This is with an unchanged working conf file from RC7 (which, aside from comments, nothing has changed config-wise in the conf from version RC7). Now, the max mail processes were already set at 1024 (and I'm the only person using this server while testing), but just for the heck of it, I tried bumping the number up to 4096 and giving it another shot. No such luck. You can login once, but any subsequent attempts come back with the error I mentioned. This is making all versions above RC7 unusable for me unfortunately. I was hoping to get buy-off on switching from QPopper/UWImap to an all Dovecot solution with the pending 1.0 final, but I doubt they'll go for allow and RC being run on the production side. Two notes that might help(?): -I'm running this on Solaris 9, not a Linux box -Dovecot is not running in daemon mode, it's running through xinetd Here are the xinetd.conf sections that are relevant: defaults { #The maximum number of requests a particular service may handle # at once. instances = UNLIMITED # The type of logging.

[Dovecot] indexes?
by David Lee 16 Oct '06

16 Oct '06

Picture: A set of very similar UN*X IMAP servers all NFS-mounting their INBOX area (traditional Unix format) from a common "/var/spool/mail" area; activity for any given user ought to be within one box although this cannot be 100% guaranteed. There is the risk of multiple simultaneous access (e.g. simultaneous LDA/delivers; simultaneous LDA/deliver and user-driven IMAP update; etc.). So locking is an important consideration. Decent "noac,actimeo=0" seems to address this succcessfully. But indexes... What is the best place for the index files? Logically alongside the INBOX area on the shared-NFS area? Or within each UN*X machine? (Or something else?) And why? Is there documentation of what functionality the index files provide, and how, if at all, this interacts with the locking of INBOXes (and folders). Thanks. -- : David Lee I.T.

[Dovecot] quota dict (mysql)
by Peter Veerman 16 Oct '06

16 Oct '06

Hi, I have dovecot configured to make use of the dict (mysql) plugin in order to keep track of the used quota. First, as you can see in the mysql table output below it seems that values aren't stored correctly. Secondly I get all kinds of database related errors in my mail logs. The (relevant) sections of the configuration files are also included below. My question is, what am I doing wrong? Peter mysql> select * from quota; +------------------+-------+---------+ | username | path | current | +------------------+-------+---------+ | userc@domain1 | 0 | 0 | | usera@domain1 | 0 | 0 | | userb@domain1 | 0 | 0 | | userb@domain1 | 5417 | 0 | | userb@domain1 | 937 | 0 | | userb@domain1 | 3724 | 0 | | userb@domain1 | -9141 | 0 | | userb@domain1 | 4887 | 0 | | userb@domain1 | -4887 | 0 | | usera@domain2 | 0 | 0 | | usera@domain1 | 3134 | 0 | | usera@domain1 | 2177 | 0 | | usera@domain1 | 5137 | 0 | | usera@domain1 | 4953 | 0 | +------------------+-------+---------+ 14 rows in set (0.03 sec) dovecot.conf: dict { quotadict = mysql:/usr/local/etc/dovecot/dovecot-dict-quota.conf } plugin { quota = dict:storage=10240 proxy::quotadict } dovecot-dict-quota.conf: connect = host=localhost dbname=postfix user=postfix password=******* table = quota select_field = current where_field = path username_field = username dovecot.log gives: Oct 02 23:25:49 Info: imap-login: Login: user=<user(a)domain.net>, method=plain, rip=88.211.149.123, lip=10.0.0.4, TLS Oct 02 23:25:49 Info: IMAP(user(a)domain.net): Effective uid=125, gid=125 Oct 02 23:25:49 Info: IMAP(user(a)domain.net): Loading modules from directory: /usr/local/lib/dovecot/imap Oct 02 23:25:49 Info: IMAP(user(a)domain.net): Module loaded: /usr/local/lib/dovecot/imap/lib01_quota_plugin.so Oct 02 23:25:49 Info: IMAP(user(a)domain.net): Module loaded: /usr/local/lib/dovecot/imap/lib02_imap_quota_plugin.so Oct 02 23:25:49 Info: IMAP(user(a)domain.net): Namespace: type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, subscriptions=no Oct 02 23:25:49 Info: IMAP(user(a)domain.net): maildir: data=/data/postfix/virtual/domain.net/user Oct 02 23:25:49 Info: IMAP(user(a)domain.net): maildir: root=/data/postfix/virtual/domain.net/user, index=/data/postfix/virtual/domain.net/user, control=, inbox= Oct 02 23:25:49 Info: IMAP(user(a)domain.net): dict quota: uri = proxy::quotadict Oct 02 23:25:49 Info: IMAP(user(a)domain.net): dict quota: byte limit = 524288000 Oct 02 23:25:49 Info: IMAP(user(a)domain.net): dict quota: count limit = 0 Oct 02 23:25:49 Info: dict: mysql: Connected to localhost (postfix) Oct 02 23:25:55 Info: dict: mysql: Connected to localhost (postfix) Oct 02 23:25:56 Info: dict: mysql: Connected to localhost (postfix) Oct 02 23:26:37 Info: dict: mysql: Connected to localhost (postfix) Oct 02 23:27:07 Info: imap-login: Aborted login: rip=10.0.0.25, lip=10.0.0.22, TLS Oct 02 23:27:11 Info: dict: mysql: Connected to localhost (postfix) mail.debug gives: Oct 2 23:26:39 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:39 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:39 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:39 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:40 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:40 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:40 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:40 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:40 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:40 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:40 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:41 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:41 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:41 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:41 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:41 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:41 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:41 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:41 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:41 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:42 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:42 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:42 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:48 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:48 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota Oct 2 23:26:48 bubbles dovecot: IMAP(user(a)domain.net): dict_quota: Couldn't update quota

[Dovecot] Conf parsing error
by Adnae Mac Uthidir 16 Oct '06

16 Oct '06

Dear Timo, I have found a conf-parse bug in rc10. If the last line in the configuration-file a }, the parser ignore this. Example: ----------------------------- brugh ~ # cat /etc/dovecot/dovecot.conf [...] plugin { trash = /etc/dovecot/trash.conf } brugh ~ # dovecot -c /etc/dovecot/dovecot.conf Error: Missing '}' ----------------------------- Add a empty line at the end of file and you can start without errors ;) -- Mit freundlichen Grüßen Adnae Mac Uthidir mailto:adnaeuthidir@gmail.com
