[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.

Hi... I use dovecot with postfix. For dovecot's sieve plugin to work, do I need to put in my /etc/postfix/master.cf: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient} and postconf -e virtual_transport=dovecot postconf -e dovecot_destination_recipient_limit=1 ?

[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

[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. Likely 2 or 3. #ldap_version = 2 ldap_version=3 # LDAP base. %variables can be used here. base = ou=accounts,dc=cttechhosting,dc=net # Dereference: never, searching, finding, always #deref = never # Search scope: base, onelevel, subtree #scope = subtree # User attributes are given in LDAP-name=dovecot-internal-name list. The # internal names are: # uid - System UID # gid - System GID # home - Home directory # mail - Mail location # # There are also other special fields which can be returned, see # http://wiki.dovecot.org/UserDatabase/ExtraFields user_attrs = mailMessageStore=home,qmailUID=uid,qmailGID=gid,mailMessageStore=mail # Filter for user lookup. Some variables can be used (see # http://wiki.dovecot.org/Variables for full list): # %u - username # %n - user part in user@domain, same as %u if there's no domain # %d - domain part in user@domain, empty if user there's no domain user_filter = (&(objectClass=qmailUser)(uid=%u)) # Password checking attributes: # user: Virtual user name (user@domain), if you wish to change the # user-given username to something else # password: Password, may optionally start with {type}, eg. {crypt} # There are also other special fields which can be returned, see # http://wiki.dovecot.org/PasswordDatabase/ExtraFields pass_attrs = mail=user,userPassword=password # If you wish to avoid two LDAP lookups (passdb + userdb), you can use # userdb prefetch instead of userdb ldap in dovecot.conf. In that case you'll # also have to include user_attrs in pass_attrs field prefixed with "userdb_" # string. For example: #pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,qmailUID=userdb_uid,qmailGID=userdb_gid # Filter for password lookups pass_filter = (&(objectClass=qmailUser)(uid=%u)) # Default password scheme. "{scheme}" before password overrides this. # List of supported schemes is in: http://wiki.dovecot.org/Authentication default_pass_scheme = LDAP-SHA # You can use same UID and GID for all user accounts if you really want to. # If the UID/GID is still found from LDAP reply, it overrides these values. #user_global_uid = ========================= #user_global_gid = ===================

[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
by Dion Hollenbeck 27 Nov '07

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

[Dovecot] Some dovecot conf parameters

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.

[Dovecot] upgrade from version 1.0.3 to version 1.0.7

26 Nov '07

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. Is there a different format for version 1.0.7? -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools "rarely do people communicate, they just take turns talking"

[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
by Brent Clark 26 Nov '07

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

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.
