I'm preparing myself for migration to dovecot 1.0.rc15 (debian stable) and would like to create indexes before users start to login into new server to ease the load. My other option is to write a script which will log as each user and create indexes, however this seems a bit of painful way to do it.

[Dovecot] Dovecot + SASL + allow_nets
by Marc Cuypers 05 Dec '07

05 Dec '07

Hi, When using dovecot for authentication of an SASL (postfix) request, i cannot use the allow_nets parameter. The IP-address of the requester is not known in dovecot. I would like to allow sasl for certain users, others are not allowed to access via SASL. Some users can have access to imap and pop3 from certain IP-addresses. How could i combine this in then dovecot configuration? -- Best regards, Marc

Looks ok, but I hate to add new settings to dovecot.conf nowadays since there are already too many. Also then there would be two Kerberos-related settings that simply set environment variables. I'm beginning to think that maybe something more generic is needed, such as: auth default { .. environment { krb5_ktname = .. krb5ccname = ... who_knows_what_else_in_future = .. } } I think LDAP library also can accept settings from environment. Anyone on mailing list have better ideas?

[Dovecot] LIST problem with Dovecot1.1beta10
by Dean Brooks 04 Dec '07

04 Dec '07

Hi, Certain IMAP folder problems started popping up with Squirrelmail with the 1.1beta10 version of Dovecot (and possibly earlier versions). Looked into it and I am seeing odd behavior with the LIST command. Here is how to reproduce problem, unless I'm missing something obvious: a001 login dean <password> a001 OK Logged in. a002 list "" * * LIST (\NoInferiors \UnMarked) "/" "Sent" * LIST (\NoInferiors \UnMarked) "/" "Trash" * LIST (\NoInferiors \UnMarked) "/" "Drafts" * LIST (\NoInferiors \UnMarked) "/" "INBOX" a002 OK List completed. a003 list "" Trash* * LIST (\NoInferiors \UnMarked) "/" "Trash" a003 OK List completed. a004 list "" Trash a004 OK List completed. <*** What? Shouldn't it have listed Trash instead of returning nothing?> a005 list "" Trash" <*** Unbalanced quote causes total lockup! It appears that Squirrelmail, and possibly others, are using the LIST command to test for the presence of a mailbox, but it seems impossible to get an exact match. Am I missing something here? -- Dean Brooks dean(a)iglou.com

[Dovecot] procmail/formail --> Maildir
by Andre Huebner 04 Dec '07

04 Dec '07

Hello List, i switched mailformat from mbox to maildir. Now i have a little problem with procmail/formail and headermanipulation of mails. Here an example: 0 * ^From.*gmx.de | (formail -t -I"procmail: gmx.de") >> /var/spool/mail/xxxxxx So, i can add some different headerlines for later evaluation and the result is attached to inbox. Now i have the problem that i don't know name of targetfile, cause it is unique for every mail if maildir is used. I did not found a Option or other workaround to solve this case. I know, it is not a dovecot problem but i hope somebody can give a hint. Could it be a possibility to leave all unchanged? Mails could be transported to /var/spool/mail/xxxxxx and picked up by dovecot if in dovecot.conf the convert-plugin ist always activated? Thanks Andre

[Dovecot] v1.1.beta10 released
by Timo Sirainen 03 Dec '07

03 Dec '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta10.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta10.tar.gz.sig Changes since beta9: - dotlock_use_excl=yes is now the default. I think this should work in all NFS setups that are in use nowadays. O_EXCL has worked since NFSv3. - fs quota: Added "noenforcing" option - Fixed compiling with non-gcc - Fixed quota plugin crash - Lots of fixes to handling message searches, especially related to non-ASCII searches. And most importantly: It includes the new Squat full text search indexing code. There are a few things left in my TODO for it: - It's currently used only to optimize root level AND searches. So for example SEARCH (OR TEXT hello TEXT world) is still searched the slow way. - Expunged messages are never removed from the indexes. - The index could be updated while messages are being saved, but this isn't done yet. - Indexed substring length is hardcoded to 4 characters. This should be configurable, although I think 4 should work quite nicely. Lucene plugin is probably completely broken now, but it was also in beta9.

[Dovecot] dovecot process nice value
by Daniel Watts 03 Dec '07

03 Dec '07

My imap processes seem to all be running with a nice value of -15 (top priority). Is this usual? Not sure if this is a dovecot setting or something going on with my own system configuration somewhere. I know the userdb query can set the nice value but mine (a mysql query) does not... We're having problems with our mail partition being absolutely thrashed and thought over-strong imap processes might be a factor. Many thanks, Daniel

[Dovecot] 1.0.8 install trouble on Ubuntu dapper (PAM)
by John Gateley 03 Dec '07

03 Dec '07

Hi, I was running the Ubuntu dovecot package until now, and decided to upgrade because of an issue with Thunderbird. I downloaded and compiled 1.0.8, and it's not starting up. The error I'm getting is: Dec 2 15:35:04 jfootoo dovecot: auth(default): Unknown passdb driver 'pam' (typo, or Dovecot was built without support for it? Check with dovecot --build-options) D I used "./configure" and "./configure --with-pam", both give the same error message. dovecot --build-options gives: uild options: ioloop=poll notify=dnotify ipv6 openssl SQL drivers: Passdb: checkpassword passwd passwd-file shadow Userdb: checkpassword passwd prefetch passwd-file static I have a dovecot that I compiled for a different system and it includes "pam" in the Passdb line. I found a page on the web saying I might need the pam-devel package, but that doesn't seem to exist for ubuntu. I saved the output from ./configure, grepped for pam, and got: checking for pam_start in -lpam... no Any ideas? What do I need to get configure to do pam support? Thanks very much j

I don't see any mention of support for SiS (single-instance-storage) as discussed previously on the list, even for upcoming 1.2/2.0 Did this fall through a crack?

[Dovecot] namespaces, shared mailboxes
by Alexander 'Leo' Bergolth 03 Dec '07

03 Dec '07

Hi! I'd like to provide shared mailboxes with maildir that should appear like 'Shared/<mailboxname>' to the clients. Using the namespace configuration below, everything works fine, exept one thing: Mail clients (only tested with Thunderbird) won't allow to put mails directly in 'Shared/mailboxname' (the folder it is greyed out). You currently have to create subfolders and put the mails in those subfolders. Is there any workaround for this problem? -------------------- 8< -------------------- namespace private { separator = / inbox = yes prefix = location = mbox:~/mail:INBOX=/var/mail/%u } namespace shared { separator = / # hidden = yes prefix = Shared/spamrep/ location = maildir:/var/spool/mail/Shared/spamrep:CONTROL=~/Maildir/control/Shared/spamrep:INDEX=~/Mail\ dir/index/Shared/spamrep } -------------------- 8< -------------------- I'm using dovecot 1.0.8. "Server supports folders that contain subfolders and messages" is enabled in Thunderbird's advanced server settings.

[Dovecot] imaptest update
by Timo Sirainen 02 Dec '07

02 Dec '07

I finally moved imaptest to mercurial repository and added a lot of new tests to it. It now also has its own wiki page: http://imapwiki.org/ImapTest Dovecot v1.1 with dbox or cydir format is the only open source IMAP server that reports no errors with it (haven't tried non-OSS servers). Dovecot with maildir and mbox have some problems with \Recent flag handling. I guess I'll have to figure out why.

[Dovecot] Quick fix for nfs-workarounds.c
by Dean Brooks 02 Dec '07

02 Dec '07

Hi, Under Solaris 8, the rmdir() command returns EEXIST instead of ENOTEMPTY if an rmdir() is attempted on a directory with files still in it. Dovecot 1.1beta9 currently gives tons of errors in the logfile as a result of the code not checking for the right error value. The function nfs_flush_file_handle_cache_dir() in nfs-worksarounds.c probably needs to reflect EEXIST as well as ENOTEMPTY. -- Dean Brooks dean(a)iglou.com

01 Dec '07

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] 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.

[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

26 Nov '07

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 26 Nov '07

26 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

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) 21 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!
