Any known issues with these locking strategies? (RHEL 4.x default) Dovecot: mbox_locks = fcntl Procmail Locking strategies: dotlocking, fcntl() We're considering moving to all dotlocking after a recommendation from RedHat, even though we're not using NFS at all. Thanks!

[Dovecot] Received Date vs Date Header
by Jeff Grossman 01 Dec '07

01 Dec '07

I am trying to figure out why my mail clients are not correctly showing me the received date versus the date header date. I am using Dovecot 1.1B9. Here is a copy of the rawlog from Dovecot when I started up the client. Is Dovecot supposed to be sending the received date and the date header during this conversation? * OK [RAWLOG TIMESTAMP] 2007-11-30 16:48:31 * NAMESPACE (("" "."))

[Dovecot] 1.1.Beta9 deliver problem: Unknown mail storage driver raw
by Velko Ivanov 01 Dec '07

01 Dec '07

Hello, I'm new to dovecot, trying to configure a Postfix/Dovecot system. Got everything in place - smtp with dovecot SASL and imap working fine, maildir is created, thunderbird logs in successfuly .. but the Dovecot LDA gives me this error on delivery: "Couldn't create internal raw storage: Unknown mail storage driver raw". I tried searching the configuration manual, reference, google and this list's archives, but found no clue. Checked the source, but it will take me some time to figure out what is a storage driver and where is the "raw" one hiding, so if somebody could help, please .. I did it with userdb static initially - uid=dovecot_mail, gid=dovecot_mail, home=/usr/local/storage/mail/%d/%n but after reading, that some passdbs don't work with deliver&static, I moved everything to the db (found out that prefetch isn't working with deliver btw - moans about userdb_ entries not present, while the imap finds them and works happily). It didn't help. # 1.1.beta9: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot listen: mail.srv.ivanov-nest.com ssl_cert_file: /usr/local/etc/dovecot.crt ssl_key_file: /usr/local/etc/dovecot.key login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: dbox:~/Maildir dotlock_use_excl: yes maildir_copy_preserve_filename: yes namespace: type: private inbox: yes hidden: yes list: yes subscriptions: yes auth default: mechanisms: plain login user: dovecot_db passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: dovecot_mail group: wheel

[Dovecot] Zimbra benchmarking
by Timo Sirainen 30 Nov '07

30 Nov '07

Now that I have a working kvm setup, I thought I'd finally try how Zimbra works. This is mainly some microbenchmarking, so it may not have much to do with actual performance in real life. Setup: - 1GB memory given to kvm (from host's 2GB) - Intel Core 2 6600 (kvm uses only one CPU) - CentOS 5 - 15GB qcow2 image on XFS filesystem - Zimbra 5.0 RC2 RHEL5 x86_64 - Dovecot latest hg, dbox format Both Zimbra and Dovecot were tested running on the same kvm image. All data could be cached in memory, so this didn't really test disk I/O. Dovecot was run with fsync_disable=no. Running with =yes would have made its performance even better. Zimbra features/bugs -------------------- Zimbra's SEARCH command doesn't support substring searching as IMAP requires: 1 search text performance * SEARCH 136 183 227 231 232 233 245 1 OK SEARCH completed 2 search text erformance * SEARCH 2 OK SEARCH completed 3 search text performanc * SEARCH 3 OK SEARCH completed It's possible to search "performanc" in a non-standard way though: 4 search text "performanc*" * SEARCH 136 183 227 231 232 233 245 4 OK SEARCH completed This means that the upcoming Dovecot v1.1 is probably the only IMAP server that supports IMAP-compatible full text search indexes with incremental updates. (Cyrus Squat requires rebuilding the whole index from scratch just for adding one mail, which makes it kind of impractical.) Zimbra doesn't support SORT or THREAD extensions. I had trouble benchmarking more than 5 simultaneous connections in one mailbox. I'm not sure if this is a configurable setting somewhere, or if there's just some bug. The error messages that my imaptest gave looked like Zimbra was buggy, but I didn't look at them too closely. STORE command also seemed to be buggy, giving lots of "STORE failed" errors, even with just one connection. Zimbra uses 500MB of memory just to start up, so it's not exactly for hosting small installations. Login+Logout ------------ Dovecot: ./imaptest - select=0 secs=10 seed=0 clients=1 Logi Logo 100% 100% 3439 6878 ./imaptest - select=0 secs=10 seed=0 clients=10 Logi Logo 100% 100% 4415 8830 Zimbra: ./imaptest - select=0 secs=10 seed=0 clients=1 Logi Logo 100% 100% 18032 36064 ./imaptest - select=0 secs=10 seed=0 clients=10 Logi Logo 100% 100% 25519 51056 Looks like Dovecot's imap process creation hurts it a lot compared to Zimbra's thread creation. Luckily IMAP connections are usually long-living, so this shouldn't matter much, except for webmails for which you can use imapproxy in the middle.

I just got a 6 months old mail to this list and wondered for a while why it happened. Looks like the old dovecot.org was rebooted and Postfix went up and started sending queued mails. So just ignore if you got those.

Or for the elucidation of the folks that are following the list trying to decide what efforts they will have to undertake to make the switch. p.s.

[Dovecot] How to find an invalid configuration in dovecot.conf
by Laurent PELLISSIER 28 Nov '07

28 Nov '07

Hi, I'm trying to test Dovecot as an IMAP ans POP3 server but I ran into a fatal problem. On the client side (telnet) I'm trying very basic IMAP commands : $ telnet localhost imap Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. * OK Dovecot ready. 1 LOGIN lavande secret 1 OK Logged in. Connection closed by foreign host. The login succeeds but the connection hangs ! On the server side it complains that the configuration file dovecot.conf is invalid (it was copied from dovecot-example.conf) but it never tells what line number is incorrect. dovecot -a or dovecot -n doesn't complain about a syntax error or something. It works for POP3 for the same user/pass. # /opt/dovecot/sbin/dovecot -F -c /etc/dovecot.conf dovecot: Nov 28 15:43:42 Info: Dovecot v1.0.8 starting up dovecot: Nov 28 15:43:53 Info: imap-login: Login: user=<lavande>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured dovecot: Nov 28 15:43:53 Error: IMAP(lavande): Error: Dovecot is already running with PID 4369 (read from /opt/dovecot-1.0.8/var/run/dovecot/master.pid) dovecot: Nov 28 15:43:53 Error: IMAP(lavande): Fatal: Invalid configuration in /etc/dovecot.conf dovecot: Nov 28 15:43:53 Error: IMAP(lavande): Fatal: EOF while reading environment from master dovecot: Nov 28 15:43:53 Error: child 4380 (imap) returned error 89 Best regards, -- Laurent PELLISSIER @ Ecole des Mines d'Alès

[Dovecot] quick question about fs quota overhead in plugin
by Adam McDougall 28 Nov '07

28 Nov '07

Last night I enabled imap_quota so dovecot could report usage reported by disk quota. I don't intend to actually use the quota plugin to place any limits anytime soon though. How much overhead does this add to normal operations that allocate disk space? Ideally I'd like a situation where the only overhead is incurred when the user uses the mail client to specifically check their usage. Is that possible, and/or is there a better way to do this? If it does cause general overhead on the NFS filer, I could just accept it until/unless I feel it becomes a burden I cannot bear. mail_plugins = acl fts fts_squat quota imap_quota ... quota = fs ...

[Dovecot] v1.0.8 released
by Timo Sirainen 28 Nov '07

28 Nov '07

http://dovecot.org/releases/1.0/dovecot-1.0.8.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.8.tar.gz.sig + Authentication: Added "password_noscheme" field that can be used instead of "password". "password" treats "{prefix}" as a password scheme while "password_noscheme" treats it as part of the password itself. So "password_noscheme" should be used if you're storing passwords as plaintext. Non-plaintext passwords never begin with "{", so this isn't a problem with them. - IMAP: Partial body fetching was sometimes non-optimal, causing the entire message to be read for every FETCH command. - deliver failed to save the message when envelope sender address contained spaces. - Maildir++ quota: We could have randomly recalculated quota when it wasn't necessary. - Login process could have crashed after logging in if client sent data before "OK Logged in" reply was sent (i.e. before master had replied that login succeeded). - Don't assert-crash when reading dovecot.index.logs generated by Dovecot v1.1. - Authentication: Don't assert-crash if password beings with "{" but doesn't contain "}". - Authentication cache didn't work when using settings that changed the username (e.g. auth_username_format).

[Dovecot] IMAP --> Creating Folders --> trailing slash
by Andre Hübner 28 Nov '07

28 Nov '07

Hello List, i use Dovecot 1.0.7 for pop and imap on Suse Linux 10.1. I need a little help in understanding something. If i want to create a folder with outlook express or thunderbird which can also create subfolders, then i have to create these folders with a trailing slash. folders created with trailing slash are in filesystem created als real folders, "normal" folders are created as file. Is it possible to change this behavior? I want to create a folders just by typing a name without trailing slash. It should be possible to store messages in this folder or create subfolders. Is there any workaround to achieve this goal? Thank you Andre

[Dovecot] little submissions feature request
by Netskin | Corin Langosch 28 Nov '07

28 Nov '07

Hi! I'm using dovecot for a while now and really like it. Actually dovecot 1.5 on Debian AMD64. Now I have to use a cifs mounted maildir directory and found it to be quite slow, though I already tuned it a lot. The only way to get it fast was to put INDEX and CONTROL files on the local disc and so outside of the maildirs. Performance is great but the problem is with submissions to maildirs. When a CONTROL directive is given, dovecot writes the submissions file to this directory too. Now as I have two dovecots in a loadbalancer my users have to do their modifications to their subscriptions always twice (for each server in the loadbalancer). I now modified dovecot on my own to put the submissions file into the Maildir, everything else is unchanged. This works just great and as desired. Anything I missed in my setup, locking issues, ...? Otherwise it may worth adding a switch for this? A directive like INDEX, CONTROL... :SUBMISSSIONS=path... Regards, Corin

[Dovecot] Embracing .99
by Joe Allesi -X (joallesi - Coyote Creek Consulting at Cisco) 28 Nov '07

28 Nov '07

We're stuck on RHEL 4.x, so we're currently working on a plan to live in harmony with .99 for another year or so. With that said, the plan is below. Let me know if you have any other recommendations. [ ]Convert to high-performance mode vice high-security to reduce overall resource usage. [ ]Implement iptables throttling for new connections to prevent denials of service. [ ]Covert from mbox to maildir to help reduce the likelihood of corruption that lead to mailbox outages. As our overall individual mailbox usage is low, maildir seems to be a good option as mbox corruption has severely impacted a few of our high-profile applications. However, does anyone know of a sane method to use maildir on RHEL 4.x without switching over to Postfix? Thanks!

[Dovecot] Various uidlist and index errors with 1.1 on NFS
by Adam McDougall 28 Nov '07

28 Nov '07

Two nights ago I took a leap and extended my testing of dovecot 1.1 by replacing 1.0 for the approx 15 users I had on 1.0. At that time I also for the first time tried dovecot 1.1 in a load balanced 2 server configuration with indexes on NFS. I was hoping I did this right, using the mail_nfs params and 1.1 so fchown etc would flush the access cache, but I am getting a number of messages and errors that indicate things aren't happy. Attaching error logs. Some of the errors were caused by me running multiple mail clients including mutt, Thunderbird, Outlook Express, other users may be using one or more copies of thunderbird, or possibly other clients. Most commonly thunderbird. Any help or advice would be appreciated. My goal is to have shared indexes between servers since I will eventually have 4. I'd prefer to avoid maintaining some kind of user->server preference mapping in a proxy (haven't looked into it yet). Thanks. # 1.1.beta6: /usr/local/etc/dovecot.conf ssl_cert_file: /usr/local/etc/apache2/ssl/mail.pem ssl_key_file: /usr/local/etc/apache2/ssl/mail.pem login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 1000 mail_extra_groups: postlocal mail_location: maildir:%h/Maildir:CONTROL=%h/Maildir/dovecot/private/control:INDEX=%h/Maildir/dovecot/private/indexes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_plugins: acl mail_log_max_lines_per_sec: 0 imap_client_workarounds: delay-newmail netscape-eoh tb-extra-mailbox-sep namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: private separator: / prefix: mail/ hidden: yes subscriptions: yes namespace: type: private separator: / prefix: Mail/ hidden: yes subscriptions: yes namespace: type: public separator: / prefix: #shared/decs/ location: maildir:/egr/mail/shared/decs:CONTROL=%h/Maildir/dovecot/public/control/decs:INDEX=%h/Maildir/dovecot/public/indexes/decs list: yes subscriptions: yes auth default: passdb: driver: pam userdb: driver: passwd args: system_user= socket: type: listen client: path: /var/spool/postfix/private/auth mode: 384 user: postfix group: postfix plugin: acl: vfile:/usr/local/etc/dovecot-acls:cache_secs=10

[Dovecot] dovecot imap hangs
by russ 27 Nov '07

27 Nov '07

All, I recently did a fresh install/setup on centos 5 to replace my older courier-imap and all seemed to go well until today I started to notice that it simply hangs. I use thunderbird and squirrel mail and after a while it seems like I"m simply rejected. I'm almost guessing that it has to do with the session timing out and then dovecot is unwilling or unable to renew the session. I can't login and there is little or no information in the logs. I've set up a cron job to restart dovecot every 5 minutes to deal with this for now. I'm new to dovecot, what sort of info should I send to you guys? I'm using centos 5, qmail-ldap and Maildir for my mail format. OpenLDAP: slapd 2.3.27 dovecot-1.0-1.2.rc15.el5 my /etc/dovecot.conf =================== mail_location = maildir:%h namespace private { prefix = INBOX. inbox = yes } mail_debug = yes maildir_copy_with_hardlinks = yes auth default { mechanisms = plain passdb ldap { # Path for LDAP configuration file, see doc/dovecot-ldap.conf for example args = /etc/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot-ldap.conf } } =================== my dovecot-ldap.conf =================== # This file is opened as root, so it should be owned by root and mode 0600. # # NOTE: If you're not using authentication binds, you'll need to give # dovecot-auth read access to userPassword field in the LDAP server. # With OpenLDAP this is done by modifying /etc/ldap/slapd.conf. There should # already be something like this: # access to attribute=userPassword # by dn="<dovecot's dn>" read # add this # by anonymous auth # by self write # by * none # Space separated list of LDAP hosts to use. host:port is allowed too. hosts =127.0.0.1:389 # LDAP URIs to use. You can use this instead of hosts list. Note that this # setting isn't supported by all LDAP libraries. #uris = # Distinguished Name - the username used to login to the LDAP server #dn = dn=cn=Manager,dc=cttechhosting,dc=net dnpass=secret # Password for LDAP server #dnpass = # Use SASL binding instead of the simple binding. Note that this changes # ldap_version automatically to be 3 if it's lower. Also note that SASL binds # and auth_bind=yes don't work together. #sasl_bind = no # SASL mechanism name to use. #sasl_mech = # SASL realm to use. #sasl_realm = # SASL authorization ID, ie. the dnpass is for this "master user", but the # dn is still the logged in user. Normally you want to keep this empty. #sasl_authz_id = # Use authentication binding for verifying password's validity. This works by # logging into LDAP server using the username and password given by client. # The pass_filter is used to find the DN for the user. Note that the pass_attrs # is still used, only the password field is ignored in it. Before doing any # search, the binding is switched back to the default DN. auth_bind = yes # If authentication binding is used, you can save one LDAP request per login # if users' DN can be specified with a common template. The template can use # the standard %variables (see user_filter). Note that you can't # use any pass_attrs if you use this setting. # # If you use this setting, it's a good idea to use a different # dovecot-ldap.conf for userdb (it can even be a symlink, just as long as the # filename is different in userdb's args). That way one connection is used only # for LDAP binds and another connection is used for user lookups. Otherwise # the binding is changed to the default DN before each user lookup. # # For example: # auth_bind_userdn = cn=%u,ou=people,o=org # auth_bind_userdn = uid=%u,ou=accounts,dc=cttechhosting,dc=net # LDAP protocol version to use.

[Dovecot] Fwd: dovecot bug report (64 bit file offsets)
by markevich＠inbox.lv 27 Nov '07

27 Nov '07

I have found similar problem: http://www.dovecot.org/list/dovecot/2007-January/018623.html "After configure remove HAVE_PREAD from config.h, recompile and see if it works." I think I figured out where might be the problem. If the binary is compiled in the 64bit environment and you want to use 64 bit file offset you must use 64 bit equivalents of the function. Of course if you are using open/pread (which are 32 bit compatible only) the whole program functionality will be broken. You must use open64/pread64 etc. Else macros _LARGE_FILE_API should be defined in order to use large files in other case nothing will work (random parsing errors and dead indexes will appear ). As I can see there is a big issue in the dovecot. http://publib.boulder.ibm.com/iseries/v5r2/ic2924/index.htm?info/apis/pread… Regards, Andris ---------- Forwarded message ---------- No: markevich(a)inbox.lv Kam: tss(a)iki.fi Reply-To: markevich(a)inbox.lv Date: Tue, 27 Nov 2007 10:45:23 +0200 Temats: dovecot bug report (64 bit file offsets) Hello. I found 2 issues while using dovecot in the 64-bit system. Before that I was using it on the Solaris 10 32bit and everything worked fine. First issue is that it's impossible to specify Openssl library directory, there is only possiblity to specify type gnutls/openssl. But if there are 2 versions of openssl installed it's hard to specify which one we want to use, we need to play with AUXLIBS and LD flags to prevent looking in un-needed locations. I'm suggesting to add new ./configure key like --with-ssl-dir like all other programs do (why dovecot hasn't it?). For example in FC8 openssl 0.9.8b is available in the packages but latest is 0.9.8.g, and it's impossible to compile dovecot with 0.9.8b because of the missing function in it which present in 0.9.8.g. Second and most serious bug is that it seems that dovecot is unable to use 64 file offsets correctly. First problem was that I as unable to launch dovecot at all - it gave a lot of configuration file (dovecot.conf) parsing errors (which is working perfectly on the 32 bit Solaris). It was very strange because he complained that he is expecting to see '=' in the line where only comments are located. Deleting some lines at the start of the configuration file produced the error on random lines (I can't describe it in other way) but with the comments too. For example, first error complained that line 42 is incorrect (only comments are there), after deletion of 2 empty lines at the beginning dovecot complained that line 172 has errors but any way there are only comments there too. I've deleted all of the comments from the configuration file but still dovecot randomly is giving such errors. Any way dovecot is UNABLE to parse all my file, I can see it from dovecot -n. He is starting normally (time to time) but only half of the configuration file is read. Similar problems goes with the indexes dovecot.index.log - dovecot is able to create the files but is unable to read them after any access to it dovecot generates errors like unexpected eof found and file is corrupted. From all this I can assume that 64bit file offsets on a 64 bit system aren't working at all. Latest dovecot 1.0.7 (also tried 1.0.5) Fedora core 8 64bit (with latest patches and updates) Intel core duo 6300 (x86_64) XFS (only local filesystem) Regards, Andris

[Dovecot] Mailbox is in inconsistent state

Running on Fedora 7, error happening on both Dovecot 1.05, and now that I upgraded to 1.07, same thing occurs. dovecot -n # 1.0.7: /etc/dovecot.conf login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd Email client(s): Eudora 7.0.1 on XP and 6.2.x on NT both do the same thing. Protocol: POP3 Symptom: 1 - On Linux, fetchmail is bringing mail down from ISP and running it through SpamAssasin to remove spam. 2 - Still on Linux, I use Pine 4.64 to manually remove any spam or viruses not caught by SA. Exit Pine. 3 - On windoze, with Eurora, check for new mail, "ERR Mailbox is in inconsistent state, please relogin" 4 - Check for new mail second time, works perfectly. 5 - Use Pine again with new mail having arrived, same error occurs. 6 - Do not use Pine in between and error does not occur. I have tried searching the mailing list archives for this error, but it only is mentioned in conjunction with IMAP. Noticed that UIDs of some value can cause the problem. My actual user IDs start with 500, which according to dovecot.conf is the default allowable. I have made no changes to dovecot.conf at all. I also tried looking at the log, but it appears to be a binary (located in /home/<username>/mail/.imap/INBOX/dovecot.index.log) not a readable text file. thanks, dion -- Dion Hollenbeck Email: hollen(a)woodsprite.com Home Page: http://www.woodsprite.com Brewing Page: http://hbd.org/hollen Toys: 98 4Runner, 86 4x4 PU

[Dovecot] File locking problems and duplicate emails with the snarf plugin
by Adrian Barker 26 Nov '07

26 Nov '07

Two weeks ago we switched all our IMAP users (around 25,000) from the Washington IMAP server to Dovecot, and since then there have been several occasions when reading new email just hangs, and duplicate emails appear. We are using the 'snarf' plugin to copy new email to the inbox, and it looks as though the problems are caused by file locking. We have been using the Washington IMAP server for a number of years without any file locking problems, so the underlying file locking mechanism is robust. Has anyone else seen this problem ? Our IMAP servers (5 of them) are a mixture of Sparc Solaris 8 and Solaris 10 machines, and they use NFS to a central mailspool running on AIX. We are using a mixture of Dovecot 1.0.3 and 1.0.5. Any help would be appreciated, as the problem has caused a lot of disruption, but we are reluctant to revert to the Washington IMAP server because of the performance improvements with Dovecot - there has been a reduction of over 60% in NFS accesses to the filestore. dovecot -n gives: # 1.0.3: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ listen: *:143 ssl_listen: *:993 ssl_ca_file: /usr/local/ssl/certs/sureserveredu.pem ssl_cert_file: /usr/local/ssl/certs/imap-server_ucl_ac_uk.crt ssl_key_file: /usr/local/ssl/certs/imap.key ssl_cipher_list: MEDIUM:!LOW disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable: /usr/local/libexec/dovecot/imap-login login_user: pp login_process_per_connection: no login_processes_count: 30 max_mail_processes: 1500 first_valid_uid: 200 mail_location: mbox:%h/imap-mail:INBOX=/nfs/rcs/mail-spool/mail/%u mmap_disable: yes mbox_lock_timeout: 55 mbox_dotlock_change_timeout: 50 mail_drop_priv_before_exec: yes mail_executable: /usr/local/sbin/dovecot-login.csh mail_plugins: mbox_snarf mail_plugin_dir: /usr/local/lib/dovecot namespace: type: private separator: / inbox: yes auth default: passdb: driver: pam passdb: driver: passwd userdb: driver: passwd plugin: mbox_snarf: ~/imap-mail/mbox -- Adrian Barker, Internet Technology Section Information Systems University College London, Gower Street, London WC1E 6BT External phone: +44 20 7679 5140, Fax (+44) 20 7388 5406 Internal phone: x 25140 Email: A.Barker(a)ucl.ac.uk

Hello all! First of all - sorry for my english. :-) Im working now on migration from cyrus to dovecot(v1.07). Everything work`s fine for now, but some parameters at dovecot conf a mystical for me. :-) dovecot-ldap.conf: user_attrs = mail #,homeDirectory,,,, user_filter = (&(objectClass=qmailUser)(mail=%u)) pass_attrs = mail,userPassword=password pass_filter = (&(objectClass=qmailUser)(mail=%u)) What does this parameters mean? Im understand what mean a *_filter, but im do not understand a *_attrs. Yes, im read a http://wiki.dovecot.org/AuthDatabase/LDAP and http://wiki.dovecot.org/PasswordDatabase/ExtraFields But don`t understand it. :-( Ask you for help, or just say what im read this wiki again and again. --- Best regards, Proskurin Kirill

[Dovecot] Ldap Proxy
by Harrison Metzger 26 Nov '07

26 Nov '07

Hello I'm trying to do an ldap proxy but it is not working, it just continues to access the user's mailbox. I was able to do a proxy with a user in a "passwd-file", but not ldap directory. Here is part my "args" file on the passdb ldap stanza: base = dc=example,dc=com auth_bind = yes pass_filter = (&(objectClass=BCMailAccount)(BCMailEnable=true)(BCMailDovecotEnable=true)(uid=%u)(BCMailDovecotProxyHost=*)) pass_attrs = uid=user,proxy,BCMailDovecotProxyHost=host I've turned on auth_verbose, debug, etc and still can't figure out why it wont proxy. Ive tried adding user_attrs (the same as the pass attrs). I've even just put nologin in the pass_attrs but the user is still able to login, its like that field is not being processed.

Im working on upgrading to dovecot-1.0.7 from version 1.0.3 which I installed using yum. I backed up my init.d stuff so everything still works. However, when I shutdown my old dovecot version and start the new, I get an empty mailbox when logging into mail. My current config for dovecot.conf on version 1.0.3 has this for my mailbox location:mail_location = mbox:~/:INBOX=/var/mail/%u I went from uw-imap to dovecot some months ago and necessary changes to the .mailboxlist to .subscriptions.

[Dovecot] NFS lock tester
by Timo Sirainen 26 Nov '07

26 Nov '07

Anyone who has NFS, could you test: http://dovecot.org/tmp/locktest.c 1. Compile: gcc locktest.c -o locktest -Wall -g 2. Start in server 1: ./locktest temp1 3. Start in server 2: ./locktest temp2 4. Server 1 might log "unlink() failed" error after starting the second locktest, ignore that. It starts writing something like: 1 successes 12 successes link() succeeded, but link count=1 12 successes What I'd like to know is what OS you use on your NFS clients, what NFS server you use and what errors does it give (errors being those "link() succeeded/failed, but .." messages). I'm getting that "link() succeeded, but link count=1" error with FreeBSD 6.2. So I'd like to know if this is a FreeBSD bug, NFS server bug or a more common NFS problem that I should work around..

[Dovecot] Wanting to seperate MTA and Imap

26 Nov '07

Hi Current my set up is that the MTA and Dovecot (maildir) is on the same machine. Ive been asked to seperate the services from the same machine (too would like to add a secondary MTA - but thats future ideas). I read the documentation on NFS, but from other sites i have read. Most say this is NOT the best solution. My question is, how do some of the fellow dovecot users,or other companys, e.g. google etc, pull this off. If you can assist in helping me fine a solution and too help me understand, I would greatfully appreciate it. Kind Regards Brent Clark

[Dovecot] libwrap-ing IMAP and POP logins
by Edgar Fuß 26 Nov '07

26 Nov '07

Since I've been using this for maybe a year now, maybe someone else is interested in restricting IMAP and POP logins via libwrap. In addition to the attached patch (against 1.0.5) to src/login-common/main.c, src/{imap,pop3}-login/Makefile.in have to be modified to link against libwrap. Of course, the option needs to be integrated into configure in the long run.

[Dovecot] Sieve regex never matches
by frank.kintrup＠fkware.de 26 Nov '07

26 Nov '07

Hi, I found the following code on the net which should redirect all mails to another address depending on the time of day (useful for forwarding mails to work): require ["regex"]; if allof (header :regex "date" "(08|09|10|11|12|13|14|15|16|17):..:..", not header :regex "date" "(sat|sun)") { redirect "address@work>"; keep; } To check and test I simplified the regex to match all mails within a certain hour: require ["regex"]; if header :regex "date" "20:..:.." { redirect "user@domain"; keep; } Both scripts compile fine, but their regex never match. Has anyone an idea why? I'm using Dovecot 1.0.0 on Debian Etch stable. Frank

Hello, In the pass_attrs field one can map ldap attributes to dovecot attributes. I'm wondering if I can map both ldap attribuets and static attributes to a dovecot value in the same passdb section. Also, I can't seem to find what other values (if any) can belong in the: passdb ldap { args = /path/filename } stanza. Are there any other options I can put in that stanza, I can't seem to find any on the wiki. Harrison Metzger

I get only one error in dovecot.log: dovecot: Nov 25 14:21:31 Error: child 19554 (imap) killed with signal 11 So my client disconnects, and asks for the password again, and in dovecot.info I get nothing, but the logs of the new connection attempt.

[Dovecot] recalculation of maildir Quota
by Ingo Rogalsky 26 Nov '07

26 Nov '07

Hello, I intend to use maildir Quota for measurement only, not for applying restrictions. Therefore I defined rather high values. That's working as expected. Nevertheless it's not useful, because the recalculation time is to high. This takes some minutes for my own mailaccount with 250.000 mails on a NFS storage. This would be to bad, but whilst this time, the Mailclient hangs. Probably our users woulnd't accept this. Can this be done in the background? Furthermore I noticed that recalculation occurs after the file maildirsize gets longer than 30 lines (around 250-300 bytes) and not after 5120 bytes as the wiki states. Do I do/understand something wrong or is this a bug? Probably a nightly cronjob, which does calculation of Maildir-size would be a more useful alternative. Regards, Ingo Rogalsky

[Dovecot] migrating from mbox to maildir
by Erick Perez 26 Nov '07

26 Nov '07

Hi all, I have a locking problem in a Centos 4.4 linux machine with the following config: dovecot-0.99.11-8.EL4 postfix-2.2.10-1.1.el4 I use virtual mailboxes with postfix currently I have dovecot with mbox as this: default_mail_env = mbox:/var/mail/virtualmail/%d/%n The problem is that mail is being delivered to mailboxes very very slowly (sometimes up to 4 hours). In my logs, I have tons of these messages: mail postfix/virtual[24965]: CFB8878D04F: to=<REMOVED@REMOVED>, relay=virtual, delay=51, status=deferred (mailbox /var/spool/mail/virtualmail/REMOVEDDOMAINNAME/npitti: unable to lock for exclusive access: Resource temporarily unavailable) then someone told me that I need to change dovecot to maildir format. Is there a reference to change format? Or some comments about this? Thanks in advance.

[Dovecot] Squat full text search indexer redesign
by Timo Sirainen 26 Nov '07

26 Nov '07

I was writing this to beta9 announcement, but it grew so huge that I guess a separate mail is better. :) I've spent quite a lot of time this last week redesigning/rewriting Squat indexer. I think the redesign is good enough now that I'll just replace the existing squat with this new one in next release. I don't think many people are using the old squat, and there are also some bugs in it that cause some searches not to find anything (haven't tried to fix it). The old Squat indexes about 3MB/s on my machine while the new one indexes 8MB/s. Or it's actually 10MB/s, but at the end of indexing it does a compression step that merges all fragmented UID lists. That drops the index size something like 5-10%, but it's pretty slow because it has to go through all the fragmented lists. It could probably be optimized to be a lot faster, but I think I'll forget about it for now. Besides being faster there are other improvements in it: - Old squat could answer only 4 character long substring searches. New squat can answer 1..n characters long substring searches, where n can be configurable. The larger the n, the larger the index size. For example 4..10 index sizes are about 35% -> 46% -> 53% -> 59% -> 63% -> 67% -> 70% of the mailbox size (with 32MB of Dovecot mailing list archives). With both old and new squat if the search keyword is longer than n, Dovecot looks up the list of all possible n char long combinations of the word, gets a list of their common UIDs and then reads those mails to verify that the word is really found from them. - New squat can also be configured to index longer words for non-substring searches. This allows it to give a definite list of UIDs where the word is found, so Dovecot doesn't have to open those mails to verify it. However it can't give a definite list of UIDs where the substring isn't found. So it still has to do the n-char-combination lookup described above, and for those returned UIDs which aren't also in the definite-UIDs list Dovecot still has to read them to check if the substring is found or not. This could be skipped for non-standard X-FAST-TEXT and X-FAST-BODY searches which don't try to search substrings. Adding 255 char long non-substring searches to 4 char long substring searches grows the index about 7% (35%->42% for 32MB, 28%->36% for 200MB, 27%->33% for 1,4GB). Unfortunately it also grows memory usage pretty much. For a 200MB mailbox heap usage grows from 34MB to 163MB. For 1,4GB lkml mailbox heap usage grows from 80MB to 700MB. So I'm not sure if this should be enabled by default until something can be done about the memory usage. - The current list of indexed characters are: A-Z, 0-9, @.-+#$%_& and all 8bit chars. When trying to search for non-indexed characters Dovecot has to split the search word. For example "a,b" would search "a" and "b", combine the results and then open those mails to see where it really exists. The same thing happens with "a b". If the search word doesn't contain any indexable characters, Dovecot has to read all mails. This indexable character list could be changed runtime, so if a user keeps searching for some non-indexed character, it could be added to indexed characters and the index be rebuilt. - To be able to give definite replies for BODY searches squat has to keep track of whether a word was found from body or header. This also optimizes HEADER searches because then Dovecot has to search only those mails that have the word in their headers, instead of the mails that have it in either header or body. Unfortunately this makes the indexes somewhat larger again (22%->28% for 200MB), but I think this should be done by default. The header+body is stored by storing UID 1=message 1 header, UID 2=message 1 body, UID 3=message 2 header, etc. I haven't yet tried how well the UID lists could be compressed if could support only-header or only-body ranges. For example now if word is found from all headers but from no bodies, it stores the UID list as 1,3,5,7,etc, while it could be stored as simple "only bodies, 1:7". I guess the UID list compression could use all kinds of other algorithms as well. Currently it supports only the whole list being either a bitmask or UID range. A long UID list might compress better as a bitmask +range combination. UID lists take most of the Squat space, so even small improvements can give huge benefits. If you're interested in trying, you can download the current test code and modify uidlist_write_array() for writing and node_uidlist_get_at_offset() for reading. http://dovecot.org/tmp/test.c http://dovecot.org/tmp/test-uidlist.c Place to src/plugins/fts-squat/, run with ./test some-mbox-file Another somewhat different idea to substring indexing (suggested to me by someone else) would be to index the messages' words normally like most indexers do, and then use Squat indexes for those words. So for example when searching for "ord" it first looks up all words that contain "ord" substring in them. Then it looks up message UIDs for those words, and the resulting UID list is a definite list of messages that has the substring. I'm not sure how well the above would work in practise. If the list of words would be mostly static it would work great. Unfortunately every mail has at least two unique strings: Message-ID and Received header's ESMTP ID. Dovecot must be able to search those as well. Also with some languages, like Finnish, a single word can be written in tens of different ways and combined with other words. A quick preliminary testing for 32MB Dovecot mailing list shows: - 142265 unique words takes 2,0MB, one per line - indexing those words creates 6,7MB Squat indexes So not including extra overhead for the unique word index, these use a total of 8,8MB. 4-char-substring Squat indexes for the same mailbox take 8,5MB and 4-char-substring+255-char-full-word Squat indexes take 11MB. So this doesn't look very promising.

[Dovecot] Configuration Error
by Mike McGonagle 25 Nov '07

25 Nov '07

Hello, I am a newbie when it comes to Dovecot, and in following this ( http://workaround.org/articles/ispmail-etch/ ) document in setting these things up, I have run into an error that I am not quite certain what to do... I am running Ubuntu Gutsy Gibbon, and using 1.0.5 for Dovecot. The message I am getting when I try to 'restart' Dovecot (using '/etc/init.d/dovecot restart') is: Error: Error in configuration file /etc/dovecot/dovecot.conf line 505: Protocol section not allowed here (section changed at line 505) Fatal: Invalid configuration in /etc/dovecot/dovecot.conf ...fail! Does this mean that I need to move this section of the configuration file to a different spot in the file? All I did was uncomment these things, and make the changes described in the link above, I would think that because this is just an edited version of the configuration file, that something like this shouldn't happen. Any help would be appreciated. Thank you, Mike -- Peace may sound simple—one beautiful word— but it requires everything we have, every quality, every strength, every dream, every high ideal. —Yehudi Menuhin (1916–1999), musician

I order to investigate a locking problem, people in this forum suggested to upgrade from 0.99 to 1.0. Which is obviously a good response.

[Dovecot] dspam integration
by Eugene Prokopiev 24 Nov '07

24 Nov '07

Hi, I see http://johannes.sipsolutions.net/Projects/dovecot-antispam and http://blog.cynapses.org/2007/09/13/dovecot-dspam-plugin/ solutions. Second git repo is not answer, first one is cloned, but I see some drawbacks with it. Dspam backend is more native solution but libdspam using instead of dspam external binary looks like preffered way to integrate dspam. Another problem is waiting for dspam child process exit, so IMAP session is blocked. Why not to fork and forget dspam child process? Email sender backend is non-blocking, but using MTA is great overhead. Calling external program with some args and mail body via pipe can be more suitable way, so external program may be dspam binary directly or shell/perl/python filter to any antispam engine via sendmail or something else. Has anybody plans to implement this features or it will be better to try it myself?

[Dovecot] Weirdness and Questions...
by James 24 Nov '07

24 Nov '07

version 1.0.7 OK, so here is my weirdness. I sent mail to the server from the command line. mail username@localhost < /etc/passwd When I open /var/spool/mail/username I can see 2 messages. The "system" message at the top and the the message produced from my command line email. If I HUP the process that runs xinet.d and re-open the users mail spool the 2nd email disappears which I wouldn't expect. Has anyone seen this before. My SMTP server could be EXIM or Sendmail. My co- admin is in the process from switching over from to EXIM. I am not sure if the SMTP server has anything to do with it or not. I can see the contents of all the email in ~/mail which is rsynced from my old server so that seems to be working properly. I have mail_locatiion in my config file, do I need anything else? mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u In my list of mailboxes that are in ~/mail I see 2 folders that I'd rather not see. There .customeflags and .INBOX Anyway to hide these, as they are not needed in my opinion. Thanks, James

[Dovecot] Broken system.
by Marcelo Iturbe 22 Nov '07

22 Nov '07

Hello, I had an Inbox with 975,604 emails on ext3 filesystem. I keept getting dropped on the comand "copy 1:2000 inbox2", the syslog gave me an error message indicating "out of memory" problems. This despite the fact that the server has 800MB of ram free. Anyways, I asked if I could manuanlly move the files at the filesystem level or if that would mess up dovecot (break the GUIDs etc). I was informed that dovecot does not use GUIDs and that I could go ahead and move the emails at the shell level. So I did that, now the /cur folder only has 40,000 emails, but when I connect to the account via telnet, I still get the following: telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK Dovecot ready. 110 login somelameuser somelamepass 110 OK Logged in. 111 select inbox * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 975604 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1188426666] UIDs valid * OK [UIDNEXT 979500] Predicted next UID 111 OK [READ-WRITE] Select completed. So even though there are only 40,000 emails in /cur, dovecot still thinks that there are 9756304 emails. How can I fix this? Thanks Marcelo

[Dovecot] dovecot loading during boot
by Robert W Nocella 22 Nov '07

22 Nov '07

I have two RHEL4 email servers running postfix/MailScanner which use dovecot. They work great. But during bootup the nfslock script in my init.d loads rpc.statd and calls portmap to get a port number. Portmap keeps giving rpc.statd the imaps port number (993). I then have to stop my mail server services, manually start dovecot, then restart the mail server services and everything goes merrily on its way. Stopping the mail server services drops rpc.statd from using port 993(according to netstat -tlnp). This allows dovecot to take it by default. How to I reserve imap and imaps ports exclusively for use by dovecot. The imap and imaps ports are listed in /etc/services.

When I receive a mail that is addressed to my email address and also with a cc to a mailinglist I subscribe to, I get two mails, which I guess is expected...

[Dovecot] pop3_lock_session and NFS
by salimlist＠sdv.fr 22 Nov '07

22 Nov '07

Hello, I need an advice about POP3 and NFS with Dovecot 1.0 (as 1.1 is still tagged beta) . I currently have all messages and indexes under a NFS partition . I thus turned cache off using actimeo=0 . Of course, my current architecture does not allow me to keep the same user on the same dovecot server. Now, I have some NFS issues with high percentages of getattr() . If I understood well, the cache must be disabled, because of the case of 2 differents computers could log on the same time and mess up the index file . If I use the directive pop3_lock_session and enable it, that should block conccurent pop3 access using a lock file . Can I consider it safe enough to turn on the NFS cache (ie removing actimeo=0) ? Thanks in advance Salim Ps: For you info, we use dovecot here for a big cable broadband ISP, with 2,000,000 mailboxes using 30 dovecot POP3 servers,10 dovecot proxy servers and we are really happy with your nice software, we expect a lot from 1.1 .

[Dovecot] Limiting the size of index files

Is there a way to limit the amount of disc space dovecot will use for its index cache? Other than putting that on a separate partition, I mean. We host our mail data on the file server, however, the index files are located on local discs on each of the mail servers and seem to grow without bounds. We're above 250M now and soon /var will run out of space. Thanks for any help.

Hello, When trying to run dovecot I am getting the following error :- Error: Error in configuration file /usr/local/etc/dovecot.conf line 923: Unknown section type (section changed at line 923) Fatal: Invalid configuration in /usr/local/etc/dovecot.conf The following section is at line 923. userdb static { args = uid=5000 gid=5000 home=/var/spool/vmail/%d/%n allow_all_users=yes } It seems to be that dovecot does'nt understand the section, but I configured with support for static userdb and this was confirmed before compilation took place. OS is Solaris 9. Any advice would be appreciated. Thanks, David.

[Dovecot] Problems executing dovecot.
by Marcelo Iturbe 21 Nov '07

21 Nov '07

Hello, I am running OS: Ubuntu 6.06.1 LTS dovecot # 1.0.7 Beta Problem: I have all the email delivery set up with maildir. I currently have an account which has 297,261 emails in the Inbox. Here is a transcript of a telnet session with the server: * OK Dovecot ready. 110 login somelameuser lameuserspass 110 OK Logged in. 111 select inbox * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 297261 EXISTS * 149522 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1188426666] UIDs valid * OK [UIDNEXT 301157] Predicted next UID 111 OK [READ-WRITE] Select completed. 112 copy 1:100 toBeProcessed Connection to host lost. I keep getting dropped... My original idea was to move the files via command prompt, but I wasn't sure if that was allowed, thought I might mess up the UIDs. How could I move the emails into other directories (folders) so that a regular IMAP conector can process the emails?

[Dovecot] Received Dates/Squirrelmail
by Jeff Grossman 21 Nov '07

21 Nov '07

I am trying to figure out an issue I have with the e-mails in my inbox showing up in Squirrelmail. I sometimes get (more often than I care for it to happen) e-mails which show up as new either many hours ago or days ago. I have one particular e-mail that in Squirrelmail is showing a data of Tue, 8:23PM. The received header of that e-mail shows: Received: from murphy.debian.org (murphy.debian.org [70.103.162.31]) by apple.stikman.com (8.14.1/8.14.1/Debian-9) with ESMTP id lA1JGTli011052 for <x>; Thu, 1 Nov 2007 12:16:35 -0700 And the date header of that e-mail shows: Date: Tue, 30 Oct 2007 23:23:11 -0400 I have tried changing the Squirrelmail setting under Display Settings which says Use Received Date. Both options, yes and no makes the mail display the same way in Squirrelmail. Is this a problem with the way Dovecot is sending the information to Squirrelmail, or is this a problem with the way Squirrelmail is interpreting the data from Dovecot? Dovecot version is 1.1beta5 Squirrelmail is version 1.4.11 Thanks for any help you can offer me. Jeff

[Dovecot] Throttle New Connections?
by Joe Allesi -X (joallesi - Coyote Creek Consulting at Cisco) 20 Nov '07

20 Nov '07

All, Is anyone using iptables (recent module), or any other alternatives, to throttle the number of new imap or pop connections per minute? We have some applications that like to login every second to pull mail using imap, so we'd like to protect the entire dovecot server from these applications. We've already made the change over to high-perf mode, but we still need some type of denial of service protection. Any real-world data would be appreciated. Thanks!

[Dovecot] Just getting started
by Randall Donaldson 20 Nov '07

20 Nov '07

This is my first attempt at creating a mail server. I'm running postfix and dovecot on Fedora 7. So far the process has been very enlightening. I currently have the server able to send and receive messages for a domain from the server machine itself. In addition, I can SMTP from any client set up on the LAN by logging in. However, I cannot retrieve messages from remote clients on the LAN. Thunderbird reads "Connected to" {servername} across the bottom, then times out. I tried to telnet to port 110 on the server, and I no response, just hangs. Not sure where the problem lies. Thanks for any assistance. here's the output of dovecot -n: # 1.0.7: /etc/dovecot.conf login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd Randall Donaldson Information Technology Stolze Printing

[Dovecot] How to write plugin

Hi, Where can I find documentation for plugin writers? Now I see mail-log-plugin source, but I can't understand how entry points (functions mail-log-plugin-init and mail-log-plugin-deinit) are defined to execute some actions on load/unload/copy messages. Can anybody comments this?

[Dovecot] Helping OS's page cache
by Timo Sirainen 20 Nov '07

http://dovecot.org/patches/1.1/fadvise.diff http://dovecot.org/patches/1.0/fadvise.diff These patches try to tell kernel when mail files are wanted to be read and when they're wanted out of memory, so the memory could be used for more important things such as index files. I'd like to hear if someone sees any actual changes (for better or worse) in the system load because of this. I'm not sure if I should add this to v1.1 and if it should be enabled by default.

[Dovecot] imap process consuming 100% CPU (Dovecot 1.0.3)
by Robert Tomanek 20 Nov '07

20 Nov '07

Hi, I have yet another problem with Dovecot: sometimes (rarely, maybe once every few days) one of the imap processes will 'hang', consuming all available CPU time. It does not seem to 'finish' in any reasonable amount of time (in one instance I waited a few days). This process will not even exit gracefully, it needs to be killed with 'kill -9 <PID>'. It has just happened again.

[Dovecot] mail_location backends
by Harrison Metzger 19 Nov '07

19 Nov '07

Hello, Where I work we have have an interesting setup, we have 2 machines with mail accounts on them and both have dovecot. We would really like to centralize all the mail accounts on one machine, but unfortunately the administration has not approved it. However, if we could create the "illusion" that they are on the same machine that would be acceptable. If we have a 3rd machine, lets say called mail.example.com, could we install dovecot on it (using LDAP authorization), such that when a user connects to this machine, it then connects to one of the 2 other machines to retrieve their mail (instead of reading from /var/spool/mail). So in essence, the mail backend is just another POP or IMAP server. In the ldap directory we could have a field that says the mail location is: "imap://machine1.example.com" for some users and "imap://machine2.example.com" (Of course it dosent have to look like that, but I hope you get my idea), then dovecot would make a connection to those servers and read the user's mail. Does such a backend even exist? Can dovecot's plugin support register a mail_location backend (such as mbox:/blah/blah, ...)? Harrison Metzger

[Dovecot] MANAGESIEVE patch v9 for dovecot 1.0.7
by Stephan Bosch 19 Nov '07

19 Nov '07

Hello Dovecot users, Since v8, I have updated the MANAGESIEVE patch to fix various issues reported by users. Although I planned to upgrade the next release after v8 to Dovecot v1.1, I release these changes for Dovecot 1.0 first. If no further major issues are found, I can upgrade to Dovecot 1.1. Change Log V9 ------------- + Definitively fixed the segfault mentioned in V8. It proved to be very time-constrained and thus hard to reproduce. The error turned out to be related to the input handling of the login daemon during authentication. + Checked for changes in the imap daemon that weren't propagated to the managesieve implementation due to code duplication. + Fixed a bug in the autodetection of the sieve storage location. + Fixed bug in the sieve storage that failed to refresh the symlink if the storage was moved. + Improved error handing in the sieve-storage implementation in various places. + Fixed the situation in which the active script link is located in the sieve storage. + Added managesieve configuration to dovecot-example.conf and made the example in this file more concise. This patch still includes (yet another) instance of the CMU Sieve source, as explained in one of my previous e-mails (http://dovecot.org/list/dovecot/2006-July/015016.html) The latest patch can be downloaded at: http://sinas.rename-it.nl/~sirius/ The README.managesieve is located in the root of the dovecot source tree after applying the patch. The dovecot-example.conf file is updated with a configuration example for managesieve. Have fun testing the patch. Don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] unlink_directory(....Trash.NewFolder) failed: Directory not empty
by Adam McDougall 18 Nov '07

18 Nov '07

I noticed the following this week. No idea how long its been happening because I have not tested deleting folders hardly at all. Steps to reproduce: 1. Create a folder "NewFolder", click on it in thunderbird so an index dir is created: ls -ldi Maildir/.NewFolder/ 1504062 drwx------ 5 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/.NewFolder/ ls -ldi Maildir/dovecot/boomhauer/private/indexes/.NewFolder/ 4198832 drwx------ 2 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/dovecot/boomhauer/private/indexes/.NewFolder/ ls -li Maildir/dovecot/boomhauer/private/indexes/.NewFolder/ total 0 4198833 -rw------- 1 mcdouga9 egrstaff 128 Nov 16 19:44 dovecot.index.log 2. Delete "NewFolder" which makes Thunderbird move both the folder under Trash, and seems to "rename" the .NewFolder index dir to .Trash.NewFolder (same inode #): ls -ldi Maildir/.Trash.NewFolder/ 1504062 drwx------ 5 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/.Trash.NewFolder/ ls -ldi Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder/ 4198832 drwx------ 2 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder/ ls -li Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder/ total 4 4198833 -rw------- 1 mcdouga9 egrstaff 128 Nov 16 19:44 dovecot.index.log 3.

[Dovecot] SIGSEGV (Segmentation fault) with antispam plugin
by Boky 18 Nov '07

18 Nov '07

Hi all. I am trying to get dovecot (1.0.rc17) running with antispam plugin. I have created another backend, which executes "sa-learn" from spamassassin's arsenal. The backend is modeled after sendmail backend. But I can't seem to get the plugin working wit either my backend or signature-log. This is my ".config": DOVECOT=/usr/src/dovecot-1.0.7 DOVECOT_VERSION=1.0 BACKEND=spamassassin-exec INSTALLDIR=/usr/lib/dovecot/modules/imap/ PLUGINNAME=antispam This is how I make the plugin: make && make install && chmod 644 /usr/lib/dovecot/modules/imap/lib90_antispam_plugin.so Since Ubuntu server does not come with dovecot sources, I have downloaded dovecot-1.0.7 and put it in /usr/src. As far as I understand, only the headers are needed, so this should not be the cause of the crash (if the headers hadn't changed). When invoked from dovecot process, the "imap" dies with signal 11.

[Dovecot] crash with fts_squat on an identified email
by Adam McDougall 18 Nov '07

18 Nov '07

I have some folders with a good amount of spam. While demonstrating full text search to a user, we found a folder that would crash dovecot while doing a fts. While splitting up the mailbox to narrow it down, I found there are a good number of messages in that folder that all made it crash in the same manner. I figured I'd narrow down a single one, get that fixed, then retest the rest. I also added to my todo list to try a full text search on as much email as I can find, to try to weed out any other problems (and see if fts is realistic to use in production). Nov 17 09:03:26 boomhauer dovecot: IMAP(mcdouga9): file message-decoder.c: line 201 (translation_buf_decode): assertion failed: (*size >= skip) Nov 17 09:03:26 boomhauer dovecot: child 14668 (imap) killed with signal 6 Let me know if this is not reproducable with the attached tgz containing a maildir with one message, I could do a local gdb if needed.

I'm running dovecot 1.0.7 now under Fedora 7 with postfix. I have no trouble at all, everything is working perfect. I use ext3 as my file system, and I store mail in maildir format. Will I have any inode, file system, issues? Is anyone storing more then 27GB in maildir format on only one ext3 partition? Here is my dovecot -n output: # 1.0.7: /etc/dovecot.conf log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 ssl_cert_file: /etc/postfix/smtpd.cert ssl_key_file: /etc/postfix/smtpd.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_max_processes_count: 512 mail_location: maildir:/home/vmail/%d/%n/ mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/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/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot-userdb-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: quota: maildir:storage=102400 [root:pts/0][~]# cat /etc/dovecot-sql.conf driver = mysql connect = host=/var/lib/mysql/mysql.sock user=mail_admin password=XXXXXXXX dbname=mail default_pass_scheme = CRYPT password_query = SELECT password FROM users WHERE CONCAT(SUBSTRING_INDEX(email,'@',1)) = '%n' AND CONCAT(SUBSTRING_INDEX(email,'@',-1)) = '%d'; [root:pts/0][~]# cat /etc/dovecot-userdb-sql.conf driver = mysql connect = host=/var/lib/mysql/mysql.sock user=mail_admin password=XXXXXXXX dbname=mail user_query = SELECT CONCAT(('/home/vmail/'), SUBSTRING_INDEX(email,'@',-1),'/',SUBSTRING_INDEX(email,'@',1),'/') as home, 5000 as uid, 5000 as gid, CONCAT('maildir:storage=', floor(quota/1024)) as quota FROM users WHERE email = '%u';

[Dovecot] Path to public folder subscription file not created in 1.1b7?
by Adam McDougall 17 Nov '07

17 Nov '07

I use CONTROL=%h/Maildir/dovecot/public/control/[namespace] for each of my public namespaces. A few nights ago, I noticed having a new user subscribe to public folders for the first time will silently fail, becuase the path up to the subscriptions file will not be created. I am pretty sure dovecot used to create it for me, but maybe that changed in a recent version, or maybe I did something to break it? Work around is to mkdir -p /home/[user]/Maildir/dovecot/public/control/[namespace] but I'd like to avoid having to do that. Once I create the directory and make sure it is writable, the client can subscribe to public folders in that namespace. If they do not have permission, it still silently fails. namespace: type: public separator: / prefix: #shared/decs/ location: maildir:/egr/mail/shared/decs:CONTROL=%h/Maildir/dovecot/public/control/decs:INDEX=%h/Maildir/dovecot/%q/public/indexes/decs list: yes subscriptions: yes

[Dovecot] Mail.app IDLE support
by Martin R. Ehmsen 16 Nov '07

16 Nov '07

Hi, I'm trying to use the new IDLE support in Mail.app on Mac OS 10.5, and it works sort of, but it seems to miss some notifications. My guess is the IDLE support in Mail.app is implemented such that it sets up a connection for IDLE notifications and then checks the mail via another connection, and because of that the "IDLE-connection" gets disconnected for inactivity after 30 min. The reason for my guess is that I get the following in my logs: dovecot: Nov 14 17:00:29 Info: imap-login: Login: user=<amanda>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:00:29 Info: imap-login: Login: user=<ehmsen>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:00:30 Info: imap-login: Login: user=<amanda>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:00:50 Info: imap-login: Login: user=<ehmsen>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:00:51 Info: imap-login: Login: user=<ehmsen>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:04:58 Info: imap-login: Login: user=<ehmsen>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:30:40 Info: IMAP(amanda): Disconnected for inactivity dovecot: Nov 14 17:43:29 Info: IMAP(amanda): Disconnected for inactivity Is there something I can do about this problem? Is the IDLE implementation in the 1.1 branch different from the implementation in the 1.0 branch of dovecot? Or can I debug this issue further? I guess these things are standardized, but it seems hard for Apple to follow a standard :-) Thanks in advance, Martin R. Ehmsen

[Dovecot] dovecot.index mtime
by Matt 15 Nov '07

15 Nov '07

Is there anyway I can get Dovecot to update mtime on dovecot.index everytime a user successfully checks there email? Or perhaps there is a better way to do what I want here. I am working on a script that I want to check when the last time a user checked there email account. If a user has not checked it in say 6 months I want to automatically suspend the account through the MTA. If they start checking it again I also want to automatically reinstate it. What I thought was a good way was to look at the mtime on dovecot.index but a user can be checking there email daily but if they do not receive a new message in say 6 months the mtime will date back to 6 months still. Ran into this with an email address used by a fax machine. So is there a better way with dovecot to determine this? I am using dovecot-1.0.rc29 right now. Matt

[Dovecot] New full text search indexer
by Timo Sirainen 14 Nov '07

14 Nov '07

As described earlier (http://dovecot.org/list/dovecot/2006-December/018055.html) Dovecot nowadays has full text search indexing support in CVS HEAD. Currently there are two backends: Lucene and Squat. Lucene's problem is that standard IMAP SEARCH command can't be used with it without breaking IMAP RFC. So Lucene can be used only with non-standard X-BODY-FAST and X-TEXT-FAST search commands. Squat's code then is quite complex and it's pretty slow. It works with 4 character blocks, so it can answer: - Search string < 4 characters: Can't answer anything - Search string = 4 characters: Definite yes/no - Search string > 4 characters: Probable yes / definite no Since search strings are usually more than 4 characters, Dovecot uses the index only to filter out messages which definitely won't match and then does regular searching for the non-filtered messages. It works ok, but it could work better. The Squat indexes take maybe 30-50% of the mailbox's size. Most of the space goes to UID lists (list of messages matching each 4 character block). For example one UID list could be "2,4-10,20-30". This is already stored in a compressed format by storing the UID numbers relative to previous UID, which allows storing them usually with a single byte per UID, even if the UIDs are large. So, this morning I had an idea how this could maybe be improved with two changes: 1. Don't use 4 character blocks. Instead allow variable sized paths, and keep track of the UIDs for each node in the path. So for example adding "abc" to UID 1 will place the UID 1 to node "a", "ab" and "abc". 2. Use UIDs relative to parent's UIDs. For example if node "a" has UIDs 1,3,5 and "ab" is added for UID 5, the UID is changed to 2 (3th in 1,3,5 list - 1). This can help the compression a lot. The best case scenario for the above example is if "ab" contains also 1,3,5 UIDs. Then it can be written with a single 0-2 range. With these changes, the indexer can be configured to perform in different ways. Text can be indexed in two ways: full words, and substrings within those words (as required by IMAP). I think a useful combination of these would be to index all 4 character substrings and all full words up to 10 characters or so. This kind of an index can answer: - Search string <= 4 characters: Definite yes/no - For X-BODY-FAST / X-TEXT-FAST: - Search string 5-10 characters: Definite yes/no - Search string 11+ characters: Probable yes / definite no - For standard IMAP SEARCH: - Search string 5-10 characters: Definite yes if message contains the key as non-substring, otherwise same as below. This helps only if user does a search that matches a lot of messages. - Search string 11+ characters: Probable yes / definite no UTF-8 text is indexed as bytes, but the path depth can be counted as characters instead of as bytes. I've a test program finished, and unless there are some bugs left I think it shows that this can work pretty well: Squat-like 4 byte substrings (but can answer 1-3 char queries also): Message count: 7495 Index time: 4.19 CPU seconds (7.39MB/CPUs) Node memory: 3014072 bytes (2943 kB) in 90550 nodes UID memory: 8277212 bytes (8083 kB) in 352778 lists Total: 11291284 / 32474899 bytes = 34.77% Indexing the same mailbox file with squat-test gives: - Index time: 9.55 CPU seconds, 9.63 real seconds (3.24MB/CPUs) - 4145192 bytes in 102208 nodes (12.76%) - 7286058 bytes in 305501 uid_lists (22.44%) - 11431250 bytes total of 32474899 (35.20%) So the new indexer is over twice as fast and uses slightly less space. Indexing 4 char substrings and words up to 10 chars: Index time: 5.13 CPU seconds (6.04MB/CPUs) Node memory: 6002804 bytes (5862 kB) in 615501 nodes UID memory: 9044610 bytes (8832 kB) in 519488 lists Total: 15047414 / 32474899 bytes = 46.34% So it takes somewhat more space, but definitely less than having both Squat + Lucene. No substring indexing, words up to 10 chars (Lucene replacement): Index time: 1.39 CPU seconds (22.28MB/CPUs) Node memory: 3297663 bytes (3220 kB) in 548540 nodes UID memory: 1803735 bytes (1761 kB) in 213554 lists Total: 5101398 / 32474899 bytes = 15.71% Is there a need for Lucene anymore with this kind of a speed and disk space usage? :) The above tests are run with everything being indexed except space and control chars (ie. practically space + tab). If only alphanumeric characters are indexed, the total lines are (in same order as above): Total: 7048664 / 32474899 bytes = 21.70% (-13.07%) Total: 9610543 / 32474899 bytes = 29.59% (-16.75%) Total: 3963335 / 32474899 bytes = 12.20% (-3.51%) There are probably still a few optimizations that can be done to get the disk space usage even lower. I did spent quite a lot of time making it use less CPU though. Even tried a bit different coding style variations in the critical functions to get gcc to create faster code.. One interesting thing I noticed was that binary searching a character from a char array was slower than just sequentially going through the characters. I tried adding checks to do it only if the array was big, but it was always slower. Maybe something to do with CPU cache. If you want to try yourself, the test program is in http://dovecot.org/tmp/new-indexer.c

[Dovecot] Using Dovecot as Asterisk PBX voicemail server
by Kenneth Porter 14 Nov '07

14 Nov '07

I'm reading the Asterisk book, 2nd edition, and it describes how one can set up voicemail to be delivered by IMAP to a voicemail folder. Asterisk can monitor flags on the folder so that the "message available" light on one's phone tracks the state of the "read" flag in the folder. One can either dial in for one's voicemail or listen to it from one's favorite IMAP client. (Dovecot is mentioned in the book.) I'm wondering how one would set up auth for this? Asterisk needs to log in to the account to deliver the voicemail and to check its state, but I wouldn't want to put everyone's mail password in plaintext in Asterisk's voicemail.conf file. Would I set up a separate IMAP account for each user to hold their voicemail, and use simple passwords (such as the PIN they use for phone access to voicemail) in the Asterisk config? Or is there a way to set up Dovecot to allow a second user to login to a specific IMAP folder in all accounts, in the same way the local delivery agent has write access to all users' mailbox? Google's page for the book: <http://books.google.com/books?id=vtQxJ3oSm64C&dq=asterisk+book> Dovecot mentions: <http://books.google.com/books?id=vtQxJ3oSm64C&dq=asterisk+book&q=dovecot#se…>

Hi list, Here is thing im trying to accomplish. I would like to setup public folders which resposible for delivering mails for some speical addresses like info(a)example.com. And it will be perfect if "seen" status for this folder will be saved per user. I mean if one user read message and set it as read other user should see it still as unread. As I far i know there some limitation in 1.0 tree but not in lates 1.1. My question is can I do such setup with dovecot+postfix. Im really appreciate for simple examples how can i accomplish this kind setup if it possible :)

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta8.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta8.tar.gz.sig Changes since beta7: - Added a new "raw" mail storage backend which allows opening files/streams as single mail mailboxes. deliver uses this now instead of opening the incoming mail as a mbox. So deliver should be now faster and it doesn't anymore remove Dovecot's private mbox headers if you're not using mbox. - Cache file tracks message expunges again - All kinds of other fixes - Some optimizations I think we're getting closer to v1.1 RCs.

[Dovecot] v2.0 / Master/config rewrite
by Timo Sirainen 11 Nov '07

11 Nov '07

If anyone's interested, I updated my master/config rewrite to latest Dovecot v1.1 tree and added it to hg: http://hg.dovecot.org/dovecot-master-rewrite/ It probably doesn't work, but with the exception of plugins it compiles anyway. :) I'm thinking that maybe after v1.1.0 I could continue with the rewrite and create v2.0 after all instead of v1.2. Just look at how much cleaner deliver.c is :) http://hg.dovecot.org/dovecot-master-rewrite/file/59ebbfcf21cb/src/deliver/… vs http://hg.dovecot.org/dovecot/file/eb4f1fbeecda/src/deliver/deliver.c Another thing with v2.0 I was thinking about was to change index file formats to be more efficient.

[Dovecot] some mail accesses in dovecot 1.1 stall for a bit (in progress)
by Adam McDougall 11 Nov '07

11 Nov '07

I noticed this in an earlier beta and took a note, and I still see it sometimes in 1.1b4, but it is only occasional so I have not tracked down yet what dovecot is doing. Just a FYI for the list incase others see it and to say that its an issue I tend to track down that I did not see in 1.0, and its been low on my list until now. Sometimes when I login to dovecot and read a message from an imap maildir folder, the message contents do not load for at least 10 seconds, sometimes closer to a minute, but after that first message loads, the rest seem fine in that mailbox. The time seems to vary some, usually longer rather than shorter.

Do you need a gdb backtrace for this one? I'm not sure why all of a sudden this started happening, its probably due to me adding a folder somewhere? not sure. It happened when I went to open my folder subscriptions in thunderbird. It was taking longer than usual (call this phase 1) and I noticed this in the logs: (cant remember if this was phase 1 or 2 but the error is probably the same) Nov 11 00:38:38 boomhauer dovecot: imap-login: Login: user=<mcdouga9>, method=PLAIN, rip=208.53.102.126, lip=35.9.37.190, TLS Nov 11 00:38:39 boomhauer dovecot: IMAP(mcdouga9): fchown(/egr/mail/shared/decs/temp.boomhauer.3050.af3db3ac545170a7) failed: Operation not permitted Nov 11 00:38:44 boomhauer dovecot: IMAP(mcdouga9): file mailbox-list-maildir.c: line 186 (maildir_list_get_path): assertion failed: (mailbox_list_is_valid_existing_name(_list, name)) Nov 11 00:38:44 boomhauer dovecot: child 3050 (imap) killed with signal 6 Nov 11 00:38:45 boomhauer dovecot: imap-login: Login: user=<mcdouga9>, method=PLAIN, rip=208.53.102.126, lip=35.9.37.190, TLS Nov 11 00:38:45 boomhauer dovecot: IMAP(mcdouga9): fchown(/egr/mail/shared/decs/temp.boomhauer.3052.5538be060c2f9c7d) failed: Operation not permitted Nov 11 00:38:46 boomhauer dovecot: IMAP(mcdouga9): file mailbox-list-maildir.c: line 186 (maildir_list_get_path): assertion failed: (mailbox_list_is_valid_existing_name(_list, name)) Nov 11 00:38:46 boomhauer dovecot: child 3052 (imap) killed with signal 6 When I cancelled the subscription window, "phase 2" is the same thing but happening more rapidly.

[Dovecot] Outlook can't see namespace folders
by James 10 Nov '07

10 Nov '07

Hi guys i understand that you can't subscribe to the Prefix names of namespace folders right now with dovecot. But for instance if i user outlook express and it can't see the prefix name then it can't see the subfolders of that "prefix folder" either. So even though it can detect and see the subfolders it won't display them cause it can't see the "parent" Is there any fix for this? it's also kind of annoying in thunderbird but at least you can still see the subfolders. TIA James Here's my config # /etc/dovecot/dovecot.conf protocols = imap imaps pop3 pop3s log_timestamp = "%Y-%m-%d %H:%M:%S " first_valid_uid = 100 login_user=vmail mail_extra_groups = mail mail_debug = yes pop3_uidl_format = %08Xu%08Xv mail_location = maildir:/home/vmail/domains/%n/Maildir #default_mail_env = maildir:/home/vmail/domains/%n/Maildir auth default { mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } } # maildir namespace private { separator = / prefix = location = maildir:/home/vmail/domains/%n/Maildir inbox = yes hidden = no } # mbox namespace private { separator = / prefix = "Mbox/" location = mbox:/home/vmail/domains/%n/Mbox inbox = no hidden = no } #public spam folder namespace public { separator = / prefix = /Spam/ location = maildir:/home/vmail/domains/Spam/Maildir/ hidden = no } ssl_disable = no ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem ssl_verify_client_cert = no ssl_cipher_list = ALL:!LOW:HIGH:MEDIUM:+SSLv2:RSA

[Dovecot] Request for variable unique to each server?
by Adam McDougall 10 Nov '07

10 Nov '07

I've been looking for a variable I can use in my dovecot.conf within the INDEX= setting so I can have one index dir per imap server on NFS. I've been looking at http://wiki.dovecot.org/Variables but no variable seems to contain something like server hostname, and I've been hunting for the variable expansion code in dovecot but haven't been able to find it. %l (local IP) won't help me because when using our load balancer, %l is the same IP on all of my servers. %r is close to useful but having a local webmail server on each server means I'd end up with 127.0.0.1 being shared (also I would end up with one directory per unique user/clientIP combo). Is there a variable that holds the server hostname or something else unique per server, or could one be added, or could someone point me at the code? Thanks.

[Dovecot] UTF-8 in dovecot-sieve ?
by Arthur Pétry 10 Nov '07

10 Nov '07

Hi, Reading http://tools.ietf.org/html/rfc3028#section-2.7.2 I thought that out-of-the-box dovecot can filter messages by matching header in UTF-8. But when I tested it, it failed : (I'm using 1.0.5 with sieve plugin) Here is my .dovecot.sieve file : ---------- require ["fileinto", "imapflags"]; if allof(header :contains "subject" "filtre") { addflag "test_1"; } if allof(header :contains "subject" "là") { addflag "test_2"; } if allof(header :comparator "i;ascii-casemap" :contains "subject" "hé") { addflag "test_3"; } ---------- Only the first of the three rules do work. When I try to match a subject string with accent encoded in ISO-8859 like "hélà" : "=?ISO-8859-1?Q?h=E9l=E0?=" there is no match Am I doing something wrong ?

[Dovecot] 1.0beta7 still has SEARCH TEXT not search the FROM
by Asheesh Laroia 10 Nov '07

I just tried out 1.0beta7 and erased all my indexes and with fts and fts_squat enabled, and when I SEARCH TEXT in Dovecot, it does *not* find messages where the thing I SEARCH for appear only in the From: header. Timo, can you confirm or deny that you still see this behavior? I did clear my indexes before doing it. -- Asheesh. -- Man is the measure of all things. -- Protagoras

[Dovecot] Dovecot I/O scheduling (all versions)
by mikkel＠euro123.dk 08 Nov '07

08 Nov '07

I have experienced this on all versions of Dovecot that Ive used (1.0 - 1.1b6) using IMAP (its difficult to test if its also there with POP3). What I see is that if there is a peak in disk usage at the time of a specific request that requests stalls. The saturation of disk I/O is momentary but when its done (maybe after one or two seconds) Dovecot still waits for its I/O operation instead of continuing as soon as resources are available. Now, I would expect Dovecot to only wait until there are resources available and not stall for at long time (sometimes it stalls for like 10 seconds, and sometimes completely). This could be OS specific (Im using ZFS and Solaris 10 on Sparc) but it may also be due to the way dovecot is programmed. Theres always plenty of RAM and CPU available so thats not whats causing troubles. Is anyone else familiar with this issue? Regards, Mikkel

[Dovecot] v1.1.beta7 released
by Timo Sirainen 08 Nov '07

08 Nov '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta7.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta7.tar.gz.sig Changes since beta6: - Beginnings of unit tests, as I mentioned in a previous mail - Message parsing fixes - Cache file handling fixes Known bugs: - Cache file doesn't keep track of how much it contains deleted data, which means it could grow infinitely. This worked at some point, so I'm not sure what I did to break it. I'll figure it out later. - Apparently for some use cases v1.1 is still slower (about 2x) than v1.0. Probably more or less specific to NFS + mmap_disable=yes.

Unit testing is good, even though it's boring and not very glamorous. I wonder if you have seen or considered libtap, possibly as an optional dependency for those who care about running the tests? http://jc.ngo.org.uk/trac-bin/trac.cgi/wiki/LibTap It looks like it could almost drop in, in place of some of your existing test helpers. It is also compatible with a variety of end user test tools. However, I could see hesitation in adding external dependencies where they aren't really necessary. If you had TAP compatibility through libtap or other means, I could easily drop dovecot into our existing suite of nightly smoke tests on FreeBSD. > I'm probably going to be pretty lazy at adding more of those tests, so > if you've ever wanted to get your own code to Dovecot, now would be a > great time to do it! :) With a 5 month old and a 4 year old on hand, "copious free time" isn't my strong point, but I'll at least attempt to provide tests with any future bug reports.

[Dovecot] imaptest update
by Timo Sirainen 07 Nov '07

07 Nov '07

http://dovecot.org/tools/imaptest.c now keeps track of messages' metadata and complains if they change. It relies on Message-ID: header being unique in the source mailbox, otherwise it'll give bogus errors. I might fix that some day. I changed the code from using simple line-based parsing to Dovecot's imap-parser code. Unfortunately it looks like it's pretty slow. At least I'm pretty sure imaptest didn't take more than a few % of CPU before, while now it's showing 35% CPU usage.. I guess I'll have to profile it a bit to see what's eating the CPU. And yes, looks like it found a couple of bugs from Dovecot 1.1's MIME parsing (BODY/BODYSTRUCTURE replies change). That was actually why I wrote this code in the first place, I was trying to figure out how to reproduce a bug. I'm getting closer to my stress testing dream tool. :) http://mailman1.u.washington.edu/pipermail/imap-protocol/2007-March/000413.…

I finally added beginnings of unit tests to Dovecot v1.1 code tree: http://hg.dovecot.org/dovecot/rev/4e4a5d6bb2cb There are currently just a couple of tests implemented in test-lib (lib/ functions) and test-mail (lib-mail/ functions). I'm probably going to be pretty lazy at adding more of those tests, so if you've ever wanted to get your own code to Dovecot, now would be a great time to do it! :)

Hi people Just switched to Dovecot yesterday, and I've already got about five reports of users with duplicate mail in their inbox :-/. Not as bad as lost email, mind you, but pretty annoying still. Checking the server log, it says: postfix/smtpd: disconnect from unknown deliver: msync() failed with index file maildir/dovecot.index: Input/output error unionfs: new lower inode mtime (bindex=0, name=maildir) dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error IMAP: Disconnected: Internal error occurred. Refer to server log for more information. This is dovecot version 1.0.3, the log presented here relates to only one user; user name snipped for anonymity purposes. Afterwards things just get worse and worse with the affected user: dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error deliver: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: Corrupted transaction log file maildir/.SPAM/dovecot.index.log: invalid new transaction log sequence (1 >= 1) dovecot: IMAP: fscking index file maildir/.SPAM/dovecot.index dovecot: IMAP: Transaction log file maildir/.SPAM/dovecot.index.log: marked corrupted dovecot: IMAP: Corrupted transaction log file maildir/.SPAM/dovecot.index.log: invalid new transaction log sequence (2 >= 2) dovecot: IMAP: fscking index file maildir/.SPAM/dovecot.index dovecot: IMAP: Corrupted transaction log file maildir/.Junk/dovecot.index.log: invalid new transaction log sequence (1 >= 1) dovecot: IMAP: fscking index file maildir/.Junk/dovecot.index dovecot: IMAP: Transaction log file maildir/.Junk/dovecot.index.log: marked corrupted dovecot: IMAP: Corrupted transaction log file maildir/.Junk/dovecot.index.log: invalid new transaction log sequence (2 >= 2) dovecot: IMAP: fscking index file maildir/.Junk/dovecot.index deliver: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error deliver: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error dovecot: IMAP: msync() failed with index file maildir/dovecot.index: Input/output error What could be the problem?

[Dovecot] IMAP - Empty attachments error
by Tomáš Klandra 06 Nov '07

06 Nov '07

Hallo, I have one problem with the following configuration: - server: debian, dovecot used as an IMAP server, version 0.99.14. - stations: windows 2k/XP, mailer seamonky 1.1.4 Sometimes (let's say once in 20 attemptes) when saving attachments, they are empty (zero size files). Simple re-saving them helps. I was looking on mozilla forums if it's not a bug in SeaMonkey, which looked more likely to me, but didn't find anything, so I got the idea it could be a bug in dovecot. If someone saw this as well or have any ideas, I would really appreciate any help about it, as the error is really annoying. Thank you, Tom

[Dovecot] User keywords limit to 26
by Arthur Pétry 06 Nov '07

06 Nov '07

Hi, I'm planning to use dovecot 1.0.5 for a webmail using a lot of user- defined tags. Recently, I just saw the limit of 26 of them when messages are stored in maildir format. This is an important issue for me, since I didn't find how to remove a flag from the dovecot-keywords database. Is there any plan to get rid of the keywords limit ? Or perhaps the new dbox storage format can fix that ? By the way, the comportement of Dovecot when we try to add a new flag while the limit is exceeded is strange : (C: is client and S: Dovecot) The store of the flags is ok : C: RUBY0094 UID STORE 89 +FLAGS (test_0 test_1 test_2 test_3 test_4 test_5 test_6 test_7 test_8 test_9 test_10 test_11 test_12 test_13 test_14 test_15 test_16 test_17 test_18 test_19 test_20 test_21 test_22 test_23 test_24 test_25 test_26) S: * 81 FETCH (UID 89 FLAGS (\Seen test_1 test_2 test_3 test_4 test_5 test_6 test_7 test_8 test_9 test_10 test_11 test_12 test_13 test_14 test_15 test_16 test_17 test_18 test_19 test_20 test_21 test_22 test_23 test_24 test_25 test_26 test_0)) S: RUBY0094 OK Store completed. And then when we fetch them, dovecot reply 2 times. The first time with all the flags, and the second time with only the 26 flags stored in maildir. (I suppose Dovecot try to sync the flags when we fetch it) : C: RUBY0095 UID FETCH 89 FLAGS S: * 81 FETCH (FLAGS (\Seen test_1 test_2 test_3 test_4 test_5 test_6 test_7 test_8 test_9 test_10 test_11 test_12 test_13 test_14 test_15 test_16 test_17 test_18 test_19 test_20 test_21 test_22 test_23 test_24 test_25 test_26 test_0) UID 89) S: * 81 FETCH (FLAGS (\Seen test_1 test_2 test_3 test_4 test_5 test_6 test_7 test_8 test_9 test_10 test_11 test_12 test_13 test_14 test_15 test_16 test_17 test_18 test_19 test_20 test_21 test_22 test_23 test_24 test_25 test_0)) S: RUBY0095 OK Fetch completed.

[Dovecot] Sent vs Sent Items
by Ed W 06 Nov '07

06 Nov '07

Religious wars about which is "best" aside - some mail clients seem to default to using "Sent Items" folder for saving sent mail, and others (many) default to "Sent". Seems that in the interests of compatibility and "doing the right thing" (tm) that a symlink from one folder to the other name would ensure that either default would give the same result (in a mixed client setup)? However, I wonder if someone has already written a plugin to do something simple like this? More generally I guess it's folder aliasing, so that Sent == Sent Items and perhaps there are also synonyms for Drafts/Templates? Anyone got any thoughts on this simple idea? (The prob with sym links is a) creating them at mailbox setup time and b) what happens when someone tries to delete the folder...) Cheers Ed W

[Dovecot] MySQL-SSL
by xyon 06 Nov '07

06 Nov '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello all, I've been running dovecot authenticating against a local MySQL database, but it has come time to implement it with a remote database. Instead of using stunnel, I'd rather take advantage of MySQL's native SSL support. I didn't know if this was possible with dovecot, and if it was, what config changes I might need to get it going. I found the below page/patch from some time ago and tried to use the ssl_key and ssl_cert directives in /etc/dovecot-sql.conf, but it didn't seem to recognize them (perhaps I need to compile mysql-ssl support into dovecot manually?): http://www.dovecot.org/list/dovecot-cvs/2004-July/003003.html Also, I noticed a need for ssl_ca and ssl_ca_path but am unfamiliar with how to generate what's needed if these options are required. FYI, dovecot 1.0.7 is running on CentOS 4.5, using rpm from ATrpms: http://dl.atrpms.net/el4-i386/atrpms/stable/dovecot-1.0.7-0_63.el4.i386.rpm Thanks for any advice or documentation pointers you can provide.

[Dovecot] truncated messages / attachments
by Markus Stumpf 05 Nov '07

05 Nov '07

I am currently running dovecot-1.1.beta6 (at least beta5 also had the problem) Retrieving some messages via IMAP gets them truncated and it also happens with retrieving attachments (message is HTML part of multipart-alternative, attachments are at least some PDF files). A user reported she is rather sure one of the messages was ok, before moving it to some other folder. In the filesystem the messages are there in full length. It happens with Outlook as well as with Thunderbird. We're using Maildir. After upgrading from beta5 to beta6 I have removed all dovecot.index* files of a folder with a defect message. This didn't make a difference. (Thought it could be related to some indexing problem). Any one else seeing this? \Maex -- Markus Stumpf

[Dovecot] Couldn't init INBOX: Can't sync mailbox: Messages keep getting expunged
by Tom Sommer 05 Nov '07

05 Nov '07

After updating Dovecot, one of my servers keep spamming these errors in the log: dovecot: Nov 03 14:14:18 Error: POP3(foo(a)bar.com): Getting size of message UID=4402 failed dovecot: Nov 03 14:14:18 Error: POP3(foo(a)bar.com): Getting size of message UID=4402 failed dovecot: Nov 03 14:14:18 Error: POP3(foo(a)bar.com): Couldn't init INBOX: Can't sync mailbox: Messages keep getting expunged The funny thing is the mailbox is empty, there are no mails in the folder that should be needed to be parsed It was perfectly fine before I updated, and the permissions on the folder is correct. It only affects some mailboxes as well. Any ideas? // Tom

I guess the reason is that ZFS can now make use if it's caching capabilities. Delivers activity is completely random since it's impossible to load balance a connection based on the e-mail recipient, since only the ip is known at the load balancing point. Therefore I have fsync_disable=no for deliver. It's easy to force the clients using imap/pop3 to the same server since it can be based on the ip only. Therefore I have fsync_disable=yes for imap/pop3. This changed everything. Now there's a real performance gain upgrading from 1.0.x to 1.1.x. About two or three times less disk activity overall (reads were already improved) for both reads and writes. Thats pretty neat!

[Dovecot] Dovecot write activity (mostly 1.1.x)
by mikkel＠euro123.dk 04 Nov '07

04 Nov '07

Im experiencing write activity thats somewhat different from my previous qmail/courier-imap/Maildir setup. This more outspoken in v.1.1.x than v1.0.x (Im using Maildir). Write activity is about half that of read activity when measuring throughput. But when measuring operations its about 5-7 times as high (measured with zpool iostat on ZFS). I think this might be due to the many small updates to index and cache files. Anyway since writing is much more demanding to the disk than reads dovecots ends up being slower (only a little though) than my old qmail/courier-imap/Maildir was. And the old setup didnt even benefit from indexes like Dovecot does. (What I mean saying slower is that it can service fewer users before it hits the wall). Of course theres also lots of benefits using Dovecot. Im just wondering whether this was a thing that should be focused on for later versions (maybe writes could be grouped together or something like that). Dovecot is very cheap on the CPU side so the only real limit in terms of scalability is the storage. Regards, Mikkel

[Dovecot] Sieve error messages (sieve 1.1.2, dovecot 1.1b6)

Sorry for spamming the list today:) Im getting a lot of these errors in the deliver log: deliver([recipient]): [date] Info: sieve runtime error: Fileinto: Generic Error deliver([recipient]): [date]:18 Error: sieve_execute_bytecode([path-to-sieve]) failed deliver([recipient]): [date] Info: msgid=<[msgid] >: save failed to [foldername]: Quota exceeded In this case the account is over the defined Dovecot quota limit. Dovecot knows what to do but sieve seems to throw its standard error message. Is there something wrong with Sieve or is it just that the error is misleading? This has been present in all v1.1.x I think (some changes was made to the error messages in b3 or b4 but believe this didnt change). Regards, Mikkel

hi, the current code has changed include linux/inotify.h to sys/inotify.h since 2006-01-17, but that won't work with inotify*.h as documented in the wiki. One has to either revert back to linux/inotify.h, or add #include <sys/inotify-syscalls.h> to both configure.in and src/lib/ioloop-notify-inotify.c Or, just symlink sys/inotify.h -> linux/inotify.h.

[Dovecot] IMAP vs system username logging with checkpassword auth
by dale gallagher 03 Nov '07

03 Nov '07

Hi After upgrading to dovecot 1.0.7 I noticed that the actual username is no longer logged, but rather the system user (in my case 'vmail') under which my virtual set-up runs. Now I'm unable to see which virtual users log in. Any pointers on how to configure dovecot to log the actual username given during the IMAP dialogue would be appreciated. My dovecot.conf includes the following: auth default { mechanisms = plain passdb checkpassword { args = /var/qmail/bin/qmail-vauth } userdb prefetch { } user = auth } An example logfile entry: 2007-11-03 15:41:56.027191500 dovecot: Info: imap-login: Login: user=<vmail>, method=PLAIN, rip=192.168.0.141, lip=192.168.0.10, TLS

[Dovecot] MANAGESIEVE patch v8 for dovecot 1.0.7
by Stephan Bosch 03 Nov '07

03 Nov '07

Hello dovecot users, I have updated the MANAGESIEVE patch to the latest stable version of dovecot (1.0.7). This new version also adds extra configuration settings to explicitly specify the location of the sieve storage and the active sieve script. Additionally, the README now more clearly explains the configuration of the daemon. It currently won't compile with 1.1 due to significant changes in the master code. However, because 1.1 now approaches a stable release, the next version is going to be updated to version 1.1. Change Log V8 ------------- + Fixed a few incompatibilities with 1.0.7 version. For instance, the "Logged in" message is now sent by the -login process and not by the managesieve daemon anymore. This caused a segfault every once in a while. + Probably fixed the settings problem reported by Steffen Kaiser regarding login_dir. 'dovecot -n' now reports correct results, but testing will show whether the whole problem is solved. + The managesieve daemon now accepts the sieve_storage and sieve configuration settings, so it is now possible to explicitly configure the location of the sieve storage and the active script respectively. The daemon still falls back to using the mail_location (MAIL) settings if nothing else is specified. + The cyrus timsieved does not use the + character in string literals and many clients have adopted to this behaviour. The latest managesieve (08) advises to accept a missing + from clients. The server should not send any + characters as well. This behavior is now implemented on the server. + Cleaned up sieve-storage.c: split up the sieve_storage_create function in various sub-functions for obtaining the various paths and directories. + Forced manual intervention if rescueing a non-symlink file at the active script path fails somehow. Previously, this presented the admin with a log message that it had just eaten the script, which is not very nice. + Restructured the README.managesieve file and added some more explanation with regard to the configuration of the daemon. This patch still includes (yet another) instance of the CMU Sieve source, as explained in one of my previous e-mails (http://dovecot.org/list/dovecot/2006-July/015016.html) The patch can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.7-MANAGESIEVE-v8.diff.gz The README.managesieve is located in the root of the dovecot source tree after applying the patch. Have fun testing the patch. Don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

The worst errors are things like: Oct 30 16:11:42 delta2 dovecot: IMAP(x): Corrupted transaction log file /home/spamcop-net2/deputies/dovecot.index.log: end_offset (392) > current sync_offset (388) Oct 30 16:11:42 delta2 dovecot: IMAP(x): file mail-index-sync-update.c: line 841 (mail_index_sync_update_index): assertion failed: (view->hdr.messages_count == map->hdr.messages_count) Oct 30 16:11:42 delta2 dovecot: IMAP(x): Raw backtrace: imap [0x462a7e] -> imap [0x46234c] -> imap(mail_index_sync_update_index+0x7b2) [0x44a982] -> imap(mail_index_sync_commit+0xe7) [0x447f87] -> imap(maildir_sync_index_finish+0xd2) [0x420b32] -> imap [0x4225af] -> imap(maildir_storage_sync_init+0x63) [0x4227b3] -> imap(imap_sync_nonselected+0xf) [0x41be9f] -> imap(_cmd_select_full+0xc5) [0x413f95] -> imap(cmd_select+0xb) [0x41411b] -> imap [0x415a87] -> imap [0x415b2c] -> imap(_client_input+0x75) [0x415cd5] -> imap(io_loop_handler_run+0xee) [0x4684ce] -> imap(io_loop_run+0x2d) [0x46797d] -> imap(main+0x3e3) [0x41d7b3] -> /lib/libc.so.6(__libc_start_main+0xdb) [0x2aaaaace049b] -> imap [0x410cca] When this happens, my users just get timeouts trying to do stuff. I have my messages (maildirs) and indices all stored on NFS. For locking, I have mmap_disable = yes and lock_method = dotlock Do you have any idea what is going on here? In general, I get tons of errors about corrupted transaction log files for all users. Is this normal? Thanks Jeff

[Dovecot] v1.1.beta5 released
by Timo Sirainen 02 Nov '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta5.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta5.tar.gz.sig APPEND should be working now. Also lots of fixes to handling namespace prefixes and namespaces where virtual separator differs from real separator. zlib plugin now supports opening compressed maildir files. This is done for files that have Z flag. SORT still assert-crashes sometimes. Would be great if someone could show me how to reproduce it. SEARCH TEXT or Squat indexes apparently still have some problems, but I couldn't reproduce them (http://dovecot.org/list/dovecot/2007-October/026254.html)

[Dovecot] Bug within Authentication Caching
by Matthias Waffenschmidt 02 Nov '07

02 Nov '07

Hello, there seems to be a bug in the authentication caching code when using it in combination with username_translation (using the current version 1.0.7 on FreeBSD 6). I've set username_translation to +@:@ to allow usernames of the form test+dom.ain or test:dom.ain (historical reasons force us....). If someone has a successful login using the username test(a)dom.ain, the subsequent authentication information is read from the cache, no matter which of the 3 possible usernames the client uses the next time. But if someone has a successful login using the username test+dom.ain, the following data has or has not been found in the cache: test+dom.ain: miss test(a)dom.ain: miss test:dom.ain: hit If the first username is test:dom.ain the behaviour is the following: test:dom.ain: miss test(a)dom.ain: miss test+dom.ain: hit I've added the information if the username changes for better debugging possibilities. In practice the username is of course always the same. The complete authentication part of the tested config: auth default: cache_size: 10000 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@:+ username_translation: +@:@ verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /var/pop/%d/Accounts.passwd userdb: driver: static args: uid=70 gid=70 home=/var/emtpy It looks as if Dovecot does some wrong username translations before inserting/lookup up the data in the cache. BTW: a SIGUSR2 signal to the dovecot-auth process does not give any information as suggested in http://wiki.dovecot.org/Authentication/Caching. Please do not only answer to the list as I am not subscribed. Thanks. -- Gruss / Best regards | LF.net GmbH | fon +49 711 90074-411 Matthias Waffenschmidt | Ruppmannstr. 27 | fax +49 711 90074-33 mw(a)LF.net | D-70565 Stuttgart | http://www.lf.net

[Dovecot] dovecot + LDAP + SASL?
by hadmut＠danisch.de 02 Nov '07

02 Nov '07

Hi, I would like to setup an IMAP server with SASL and LDAP support. As far as I can see dovecot supports SASL and LDAP, but not the way I need it. If I understand dovecot correctly, it has it's own set of SASL mechnisms and uses the LDAP server just to store the plaintext password. In case of authentication dovecot fetches the plaintext password from LDAP and then performs the SASL steps internally. I need to support proprietary SASL mechanisms built into an LDAP server, which are not based on just a single password. So is there a way to configure dovecot to just pass SASL through to LDAP, allowing the IMAP client to talk SASL with the LDAP server through dovecot? regards Hadmut

[Dovecot] Successful experience with auth_winbind module
by Dmitry Butskoy 02 Nov '07

02 Nov '07

Hi, Recently the support of Samba's ntlm_auth helper was added to dovecot-auth (mech-winbind.c etc.). It is alrready in 1.1, the patch for 1.0 is here: http://dovecot.org/patches/1.0/dovecot-1.0.3-winbind.patch . It allows auth against NT or AD domain. I would like to infrom all that we successfully use this new feature during 2 month and ~300 users 24x7 (an energy power company). No any failures at all! This feature allows to specify "SPA" (Secure Password Authentication) option in OE, and to avoid explicit user passwords in mail accounts. Some random notes: - In the mixed environment (both plain and ntlm methods in use), you have to specify: mechanisms = plain ntlm login i.e. "ntlm" before "login". When sending mails, OE just catch first seen and try to use it, even if you specify to use SPA in the mail account preferences. - It seems that MS Outlook requires the specifying of password even when SPA is in effect - When OE has several identities, and one of the identities has SPA for SMTP set (outgoing mail), it wins over all another identities. - "The Bat" mailer supports NTLM for reading, not sending, and requires password too. Regards, Dmitry Bustkoy http://www.fedoraproject.org/wiki/DmitryButskoy P.S. We use NTLM only, GSS-SPNEGO still not tested.

Re: [Dovecot] Dovecot push imap/imap notify support?

Mart Pirita <sysadmin(a)e-positive.ee> wrote: > Tried search, no luck, does the Dovecot include push imap/imap notify support? If you're looking for something iPhone-compatible, then "no." Theirs is a proprietary system which from what I've read, seems to use SMS in combination with IMAP. Wacky. (If you aren't talking about iPhone compatibility, I'm less knowledgeable, but dovecot does support IDLE-style "imap push" style notification.) Alan Ferrency

[Dovecot] mail_location and master_user rel 1.0.x

02 Nov '07

login me(a)mymail.net*theboss thebossespwd this is a great piece of software, but it has some frustrating issues. i have included my two configurations below, just FYI. the one (older) system is 1.0rc7 on mandriva 2007.0 and postfix 2.3.3 and amavisd and spamassassin and using a maildir configuration the newer system is 1.0.5 (soon to be 7) on mandriva 2008.0 and postfix 2.4.5 amavisd and spamassassin and using a maildir configuration first, i followed the instructions in this document http://wiki.dovecot.org/Authentication/MasterUsers to the letter and it works for neither the old server nor the new. specifically i was using the first example configuration. all i ever got was: Connected to mail.mailserver.com Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS STARTTLS AUTH=LOGIN AUTH=PLAIN AUTH=DIGEST-MD5] Dovecot ready. login him(a)mailserver.com*theboss thebossespwd login BAD Error in IMAP command received by server. and the auth_debug information was completely useless. if someone goes to the trouble of writing great examples they really should test to make sure they actually work. secondly: this configuration on the old server (1.0rc7) works fine: ## Dovecot 1.0 configuration file base_dir = /var/lib/dovecot protocols = imap pop3 imaps log_path = /var/log/dovecot/error.log info_log_path = /var/log/dovecot/info.log first_valid_uid = 60000 last_valid_uid = 60000 first_valid_gid=15 last_valid_gid=15 default_mail_env = maildir:/var/spool/mail/%d/%u mailbox_check_interval = 60 maildir_copy_with_hardlinks = yes mbox_locks = fcntl umask = 0077 auth default { mechanisms = plain digest-md5 user = dovecot passdb pgsql { /etc/dovecot/dovecot-pgsql.conf } userdb pgsql { /etc/dovecot/dovecot-pgsql.conf } socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = postfix group = mail } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = mail } } } but the same configuration on the newer version 1.0.5 does not work, the problem being in mail location (note changed from default_mail_location to mail_location). so i had to make a number of changes... ##

[Dovecot] receive date wrong in outlook
by Farkas Levente 31 Oct '07

31 Oct '07

hi, we migrate from exchange to dovecot. we do it with imapsync. first we try to do it with --syncinternaldates, but this fails on many messages with invalid date, so we drop this option. unfortunately after this those users who use outlook see the received date as the date we do the migration in stead of the real received date. other clients eg webmail, thunderbird etc sees the right date. so my question what can i do? it's a dovecot bug or outlook and if outlook's bug is there any workaround fro this? thanks in advance. -- Levente "Si vis pacem para bellum!"

[Dovecot] Sometimes Dovecot v1.0.3 does not accept new connections
by Steffen Kaiser 30 Oct '07

30 Oct '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, occasionally Dovecot stops to accept new connections. Already existing ones do function properly. Strace'ing dovecot-auth reveals that it is running and is authentificating users, the logfile logs new connections. However, lots of other connects just stall, before the IMAP server responds with the greeting. My user backend is a LDAP server. I've sniffed the interface, but I also don't see numerous connection attempts, so I suppose, that there is no DoS attack running. The logfile contains no warning or error except: dovecot: Oct 17 15:34:44 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:34:49 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:34:52 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:02 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:05 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:12 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:19 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:20 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:25 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:26 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:27 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:27 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:41 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:42 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:47 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:49 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:49 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:50 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:56 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:36:03 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 Does somebody has an idea, where to go to look into the issue?

[Dovecot] 1.1Beta5 Issue
by Jeff Grossman 30 Oct '07

30 Oct '07

I installed 1.1Beta 5 this weekend. I had no problems at all yesterday using Thunderbird. I started reading my mail with Squirrelmail this morning and everything was going pretty smooth. I tried to delete a daily e-mail I receive from careerbuilder.com and the IMAP process shot up to 99.9% and I was not able to do anything in Squirrelmail. I killed that process and tried it again just to be sure what it was. And it did it again. I can delete any other message with no problems, just that one causes me issues. I am not sure if Thunderbird is the same, I will have to wait until I get home tonight. If there is any troubleshooting you would like me to do, please let me know. Jeff

[Dovecot] time going back
by zbigniew szalbot 29 Oct '07

29 Oct '07

Hi all, Sorry if this is trivial. I am just concerned. In Poland we will be putting the clocks one hour behind (back) on Sunday. I once saw dovecot killing itself because I manually adjusted the clock in the past. Will it not happen in this case? Thanks for your ideas. Zbigniew Szalbot

[Dovecot] Static home while using LDAP
by David Bosque 29 Oct '07

29 Oct '07

Hello all, I've been googling for a workaround for this for nearly a week to no avail and I hope someone in the list can shed some light on it. I have downloaded and compiled dovecot 1.0.5 and applied the quota-warning to it. I have configured everything and it's working wonderfully, even the lda with the sieve plugin. This is my current relevant configuration: userdb static{ args = uid=501 gid=12 home=/var/mail/buzones/%d/%n allow_all_users=yes } passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } However, I need to obtain some more data from LDAP, so I need to switch to an ldap userdb, but want to keep the home as it is in the static configuration and not having to store it in LDAP. Is it possible to use a fixed home (as in the static userdb) while using an ldap userdb? I am looking for something similar to user_global_uid and user_global_gid but for the "home". If not, is it possible to fix or append something to the values in the user_attrs (like the following)? user_attrs = [whatever_i_want_to_append]uid=home uidNumber=uid,gidNumber=gid Regards, David Bosque

http://dovecot.org/releases/1.0/dovecot-1.0.7.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.7.tar.gz.sig Almost missed this one. I had already fixed it in v1.1 tree, but forgot to fix in v1.0 tree. - deliver: v1.0.6's "From " line ignoring could have written to a bad location in stack, possibly causing problems.

[Dovecot] lost emails with version 1.0.6
by Nishant Limbachia 29 Oct '07

29 Oct '07

Hi list members, I am using dovecot on Slackware 12.0 with postfix 2.4.5. I just upgraded to version 1.0.6 from 1.0.5 and now I am not getting emails. I am using dovecot deliver with postfix. deliver log also says email put into appropriate inbox. Starting up dovecot doesn't show any error messages. I've looked at the release notes and couldn't find any changes that should affect the config file. Here's an excerpt from dovecot deliver's log for the last two emails I've lost after upgrade. ### deliver(raghu): Oct 28 19:34:52 Info: msgid=<200710281935.AA6815928(a)stuart.iit.edu>: saved mail to INBOX deliver(raghu): Oct 28 19:40:13 Info: msgid=<200710281940.AA82444392(a)stuart.iit.edu>: saved mail to INBOX ### Any ideas? ---- tuxrules.in(a)gmail.com

[Dovecot] do 1.1b4 assertion failed: (mailbox_list_is_valid_existing_name
by Adam McDougall 28 Oct '07

I think this is where I left off last weekend. Instead of this happening at the base of one of my shared mail namespaces, it happens when I try to select a top level folder inside the namespace, or try to directly select an entire path to a folder. This only happens when ACL is enabled. Let me know if I need to provide more. Thanks.

[Dovecot] fallback for proxy?
by Cor Bosman 28 Oct '07

28 Oct '07

Is it possible somehow to configure a fallback for a failed proxy? I am using sql based proxying through dovecot, but it would be nice if you can fallback to another host if the proxy destination server is down. High availability and all.. Regards, Cor

[Dovecot] More core dump stack traces
by Lloyd Parkes 28 Oct '07

28 Oct '07

Hi all, I found a whole bunch of core files from imap this evening, so here are the stack traces from each. Unlike my last message, I don't have debugging symbols for these, so there isn't any analysis I can easily do. There were several cores with the first stack trace and one with the second trace. The core dump for the second trace is the only one I noticed. I suspect that the first trace happens when the client host goes to sleep. If so, the situation needs to be handled more gracefully. I'm currently building a copy of imap with debugging symbols.

[Dovecot] Possible Caching Bug showing up as a MIME Boundary Issue
by Kevin A. McGrail 27 Oct '07

27 Oct '07

Possible Caching Bug showing up as a MIME Boundary Issue I'm using Dovecot version 1.0.0. I was using Dovecot version 1.0.0 beta3 or alpha4. I upgraded to Dovecot 1.0.0 to make sure that was not the issue. Over the past few weeks on a server running a stable dovecot, I have seem a few emails arriving where the MIME document structure dividers are visible. I've included a screenshot showing this. Using OE6 as client. Have tried adding oe6-fetch-no-newmail per clients wiki but this seems to stop the ability to login at all. I am using two different machines with Outlook Express to access the same email. The same problem will show up on both. Usually, if I delete the .imap cache for the folder, the email comes down correctly. My dovecot -n output is: # /etc/dovecot.conf listen: *:144 ssl_listen: *:994 ssl_cert_file: /usr/local/ssl/certs/stunnel.pem ssl_key_file: /usr/local/ssl/certs/stunnel.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login max_mail_processes: 50 verbose_proctitle: yes default_mail_env: mbox:~/:INBOX=/var/spool/mail/%u mail_location: mbox:~/:INBOX=/var/spool/mail/%u imap_client_workarounds: outlook-idle delay-newmail auth default: passdb: driver: pam userdb: driver: passwd userdb: driver: prefetch The server is on a heavily modified RedHat 7.2 on x86 box with ext3 Thanks in Advance, KAM

[Dovecot] trouble deleting folders that only contain folders
by Ken A 27 Oct '07

27 Oct '07

Hi, I'm using dovecot 1.0.5 with mbox storage. Users can't delete folders that are created to 'only hold other folders'. I can create these folders with no problem. They are directories in the file system. Normal folders (which are mbox files) are deleted with no problem. I've tried with both squirrelmail and Thunderbird, and what happens when a delete is requested, is that all files within the folder's dir tree are deleted and the client is unsubscribed, but the directory tree remains. Any ideas? Thanks, Ken -- Ken Anderson Pacific.Net

[Dovecot] 1.1b3 and Maildir quota
by Rick Romero 27 Oct '07

27 Oct '07

I upgraded a 1.0 install to 1.1b3. Almost everything is working peachy-keen :) It seems faster to me, Offline Folders and 'new mail' options for Thunderbird are now working, and Mail.App doesn't seem to need the extra namespace. Unfortunately it doesn't seem to read my quotas any longer. I went through the docs, and I see the quota plugin has changed, but there doesn't seem to be a needed configuration change. Did I miss something? I used my same dovecot.conf as 1.0: I also wiped clean my /usr/local/lib/dovecot directory and reinstalled, just to be sure, but it still doesn't work :/ Is it because I use checkpassword for my auth? # 1.1.beta3: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot_info.log disable_plaintext_auth: no shutdown_clients: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_user: nobody login_process_per_connection: no login_greeting_capability: yes login_process_size: 64 login_processes_count: 15 login_max_processes_count: 512 verbose_proctitle: yes first_valid_uid: 89 mail_executable: /usr/local/libexec/dovecot/rawlog /usr/local/libexec/dovecot/imap mail_plugins: quota imap_quota imap_client_workarounds: delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes auth default: user: vpopmail passdb: driver: checkpassword args: /usr/local/vpopmail/bin/vchkpw userdb: driver: prefetch plugin: quota: maildir dell#

[Dovecot] quota problems - which Dovecot version ?
by Albert Schweizer 27 Oct '07

27 Oct '07

Hi, I've got a little problem with Dovecot IMAP. Everything works nice ( pam auth, ldap userdb, and so on ) BUT i need to uses quotas and it doesn't seem to work. I tried both ways : 1) user dovecot-ldap.conf with user_attrs, as it's shown on dovecot wiki ; 2) use the commandes "plugin {.........." in dovecot.conf But it didn't work. Strangely, when i try to use the PLUGIN command in dovecot.conf, the server crashes at start, "syntax error" in config.... I'm not sure if the quotas are supported in my Dovecot version : version : 0.99.14 release : 1.EL4 I'm using an old AlphaServer ( dec ) with Centos 4.2 installed, and it's a real mess to get yum updates. Building from sources neither worked.... Please help !!! Regards Y.V.

[Dovecot] Duplicate message
by Timothy Murphy 27 Oct '07

27 Oct '07

I'm running dovecot on my desktop and using kmail as a client on my laptop. I am very happy with this - I was previously running kmail under NFS, and this is infinitely better. There is one small issue, which is not very important. I get a small number of messages apparently duplicated. This doesn't really matter, as there is a facility Folder=>Remove Duplicate Messages under kmail, and this deals with the issue easily enough. I just wondered though why I get the duplicate messages, and if there is some simple way to avoid them?

[Dovecot] dovecot-auth: Too many open files
by Joe Allesi -X (joallesi - Coyote Creek Consulting at Cisco) 27 Oct '07

27 Oct '07

All, [version: dovecot-0.99.11-4.EL4.src.rpm] We recently experienced an issue that prevented all new IMAP logins from occurring. Although it appears that it was due to running out of available system file descriptors, I'm still not sure what the true root cause was as I can't replicate the same error in our test environment. The system file descriptor max was set at (per `cat /proc/sys/fs/file-nr`) 380081 , and we're averaging around 7,000 in use. It appears that the main issue was dovecot-auth, so does this appear to fall in line with the known PAM bug in this version? Auth config: auth_userdb = passwd auth_passdb = pam Checked maillogs (cleansed): Oct 16 11:48:05 host dovecot-auth: PAM: pipe() failed: Too many open files Oct 16 04:48:06 host imap-login: Disconnected [::ffff:<internal_IP>] Oct 16 11:48:11 host dovecot-auth: PAM: pipe() failed: Too many open files Oct 16 04:48:11 host imap-login: Aborted login [::ffff:<internal_IP>] Oct 16 04:48:11 host dovecot-auth: PAM unable to dlopen(/lib/security/pam_nologin.so) Oct 16 04:48:11 host dovecot-auth: PAM [dlerror: /lib/security/pam_nologin.so: cannot open shared object file: Too many open files] Oct 16 04:48:11 host dovecot-auth: PAM adding faulty module: /lib/security/pam_nologin.so Oct 16 04:48:11 host dovecot-auth: PAM unable to dlopen(/lib/security/pam_stack.so) Oct 16 04:48:11 host dovecot-auth: PAM [dlerror: /lib/security/pam_stack.so: cannot open shared object file: Too many open files] So, during the event I performed an strace against the dovecot-auth process and noticed the following error as well: accept(3, 0xbfe05a50, [2]) = -1 EMFILE (Too many open files) gettimeofday({1192538310, 41972}, NULL) = 0 poll([{fd=3, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL, revents=POLLIN}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=18, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=10, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=23, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=8, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=11, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=12, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=13, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=14, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=19, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=16, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=17, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=6, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=15, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=20, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=21, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=9, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=22, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=24, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=25, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=26, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=27, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=28, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=34, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=33, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=29, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=37, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=30, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=31, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=41, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, ...], 1020, 1585) = 1 gettimeofday({1192538310, 99354}, {480, 0}) = 0 Then I checked for the current network connections: netstat | grep imap | wc -l 42 Then used lsof to check for open files: while true ; do lsof | awk '{ print $3 }' | wc -l ; sleep 4 ; done 21728 21668 (restarted dovecot) 1838 1953 1864 2066 2018 2020 2036 2189 2661 2558 2490 (cont @2,000) Thanks!

[Dovecot] Problem in mbox-sync.c
by Hal Pomeranz 27 Oct '07

27 Oct '07

We've just cut over to a new mail server running Dovecot 1.0.5. The underlying OS is RHEL 5. User mailboxes are stored in Unix mbox format on a local ext3 file system. The MTA on the system is the default RedHat version of Sendmail 8.13.8 with procmail for local delivery. We're using a combination of dotlock and fcntl style locking. The output of "dovecot -n" for this system appears below my signature. Periodically we see errors like the following in our logs: Oct 21 19:36:01 postoffice1 dovecot: POP3(someuser): file mbox-sync.c: line 1433 (mbox_sync_handle_eof_updates): assertion failed: (file_size >= sync_ctx->expunged_space + trailer_size) Oct 21 19:36:01 postoffice1 dovecot: POP3(someuser): Raw backtrace: pop3 [0x809eda1] -> pop3 [0x809ecbc] -> pop3(mbox_sync+0x1088) [0x806c4e8] -> pop3(mbox_storage_sync_init+0x3e) [0x806cb6e] -> pop3(client_create+0x1a4) [0x80552a4] -> pop3(main+0x556) [0x8057236] -> /lib/libc.so.6(__libc_start_main+0xdc) [0x304dec] -> pop3 [0x8054a11] Oct 21 19:36:01 postoffice1 dovecot: child 24409 (pop3) killed with signal 6 Note that while the above log is for a POP3 user, we also see similar behavior when some users access mail folders via IMAP as well. The real problem with this behavior is that sometimes, but not in all cases, the process will leave behind a dotlock when it exits. If the abandoned dotlock is on the user's inbox, then procmail won't deliver new mail to the user until the lock is cleared. This is a big problem. Anybody seen this behavior before and/or know what's causing it? Can anybody suggest ideas for further debugging this issue? We'd appreciate any help that you all can provide.

[Dovecot] master user can not login with digest-md5 password
by Daniel 27 Oct '07

27 Oct '07

Hi! I'm trying to use a master user, here is what I'm doing: dovecot.conf: auth default { [...] passdb passwd-file { args = /etc/dovecot.passdb_master pass = yes master = yes } passdb passwd-file { args = /etc/dovecot.passdb } [...] } (Dovecot said that one can not place the passdb containing "master = yes" last, why?) This only works if the master user (in the master passwd file) has PLAIN password scheme. It doesn't work with DIGEST-MD5. Here is the log when it's in DIGEST-MD5: auth(default): passdb(master,84.x.x.x,master): Master user logging in as leva auth(default): digest-md5(leva,84.x.x.x): password mismatch imap-login: Disconnected: user=<leva>, method=DIGEST-MD5, rip=84.x.x.x, lip=212.x.x.x, TLS When the master password is in PLAIN scheme, I can login as anyone. I'm using dovecot-1.1beta4. Daniel

[Dovecot] Messages not marked as read
by Manilal K M 27 Oct '07

27 Oct '07

Hello everybody, Recently I have migrated my IMAP server from Courier-IMAP to dovecot. The migration was successful and all the users are happy due to the speed of the new IMAP server. We are using Horde-3.2+IMP-4.2 as the webmail client. But one of the users is having some unusual issues with his mailbox. Whenever he clicked and open a new email, it's never marked as read. He has to click and open several times to get it marked as "Read". I checked the dovecot version and found that we have a unstable version. So I upgraded to the latest stable version(1.0.5). But still occasionally he has the same issue. Does anyone have experienced similar issue. Please share. regards -- Manilal K M. http://linuxeyes.blogspot.com http://flossvalley.blogspot.com Better to light one candle than to curse the darkness.

[Dovecot] Keywords (labels) support via virtual folders
by Robert Tomanek 27 Oct '07

27 Oct '07

Hi all, while I am rather a beginner when it comes to IMAP, I was thinking whether it would be possible (and feasible) to implement setting and unsetting of IMAP keywords with the means of virtual folders in Dovecot. The background is that the IMAP keywords seem to be a very useful thing to me: I would often like to be able to 'tag' a message so that it is easy to group with other similar messages and easy to find/ browse later. The problem is that not all IMAP clients support this functionality (as far as I am aware, mine which happens to be The Bat! does not); the only way of achieving similar results is using regular folders for grouping messages but this has several disadvantages, the most prominent one being unable to assign more than one 'tag' to a message this way (without copying a message). What I am thinking of is a server-side 'helper' that intends to achieve functionality similar to native client keywords support by the means of providing 'virtual folders' (as opposed to regular folders that we've known for a long time). The server would expose a list of virtual folders (user defined, either server-side by modifying the configuration, or client-side, by using the existing 'create regular folder' folder functionality but using a special name format that would be recognized by the server to be virtual folder related). These virtual folders would, upon moving a message to them, apply a keyword to the message (but the message would not be moved as it would be the case with regular folders). Upon moving a message from a virtual folder, the keyword would be reset. This means that the messages would not normally be moved from their place in existing hard folder structure but they would additionally be flagged with a keyword (or more of them) and be visible in respective virtual folders. The result is: - keywords support for clients that do not natively support it, - leaving existing message folder structure intact, - support for multiple keywords/ labels per message (one virtual folder = one keyword), - browsing flagged messages via respective virtual folders. What do you think of it? While I've been toying with this and similar ideas for a long time, what I propose above is of course heavily influenced by the recent addition of IMAP access to Gmail ([1]). While I still do not have it enabled for my account, I presume this is how the Gmail labels get translated to IMAP client ([2], [3]).

[Dovecot] few questions about 1.1*
by Daniel 27 Oct '07

27 Oct '07

Hi! I'm testing 1.1, and have some questions. (How) Can I override the default maildir++ quota setting (I mean quota_rule) in the userdb, so that one won't have quota at all. Right now I'm setting a very high limit in the userdb with quota_rule=*:storage=99G in the extra field. Prior to 1.1 I was using 1.0 and had fs quota. I've had set up dovecot so that the indexes were stored on another partition where there were no fs quotas for the users. Now I'm trying to use maildir++ quota, and wondering if there is still any use of keeping the index files on a separate partition. This will be maybe a bit stupid, but do I still need the quota plugin to be loaded in the protocol {imap,pop3,lda} sections if I'm using the above mentioned new 1.1 maildir++ quota? Furthermore, will deliver be aware of the new quota system? Thanks! Daniel

Hi! I'm guessing this is the append bug which is still present in dovecot-1.1beta4?: Info: IMAP(leva): Disconnected: EOF while appending bytes=31665/119125 This happens after sending a mail, and trying upload/copy that mail from my local "Sent" folder to my IMAP server's Sent folder. Daniel

[Dovecot] sieve filtering, rewriting subjects
by Ian P. Christian 26 Oct '07

26 Oct '07

Is it possible to modify an emails subject line in a sieve script? I've seen references to 'addtag' whilst googling, but it appears dovecots implementation doens't support it - are there any other methods? As a side note, can anyone suggest a web based script editor that works? Simply a text area to write the script in would do Thanks, -- Ian P. Christian ~ pookey.co.uk

[Dovecot] SSL help needed - "no root certificate"
by Jim Gottlieb 26 Oct '07

26 Oct '07

Hi. I've spent the past few hours trying to get SSL working right in Dovecot 1.0.5 and now I must turn to you for help. I purchased an SSL certificate from Go Daddy. I pointed ssl_cert_file to the .crt file and ssl_key_file to the .key file, but the client (Mail.app) complains: Mail was unable to verify the identity of this server, which has a certificate issued to "imap.nccom.com". The error was: There is no root certificate for this server. So I tried downloading Go Daddy's root certificate and pointing ssl_ca_file to that file, but that didn't help. So I tried pointing ssl_ca_file to the intermediate certificate sent to me by Go Daddy, but that breaks things to the point where I never even get the above message; just nothing happens at all. I'm not sure what to try next and am happy to entertain any suggestions. Thanks...
