04 Jan '08

What is correct way to backup dovecot store? Is am I right what is just enough to copy all maildir and my configuration. So in case failure I can just prepare new machine copy config, maildirs and I'm good to go with this.

[Dovecot] Optimizing POP3 performance?
by Sebastian Färber 04 Jan '08

04 Jan '08

Hello, I recently migrated to Dovecot from Courier-IMAP and i'm very happy with the IMAP Performance and Dovecot in general. The server is running qmail-ldap and i'm still using the qmail pop3 daemon for the POP3 users. Because i want to get rid of qmail completely (switching to exim) i just tried to replace the qmail pop3 daemon with dovecot too. Immediately after the migration the server became basically unusable because of the high I/O Load caused by the dovecot pop3 daemon. I did some debugging and it looks like dovecot opens every old mail in a users maildir and wants to create it's index files etc. I tried running dovecot pop3 with and without "in memory" indexes but this didn't change anything. Is it possible to disable the indexing of the old e-mails completly for pop3? I understand that dovecot is primarily an IMAP Server but i didn't expect the POP3 Performance to be that bad compared to the qmail pop3 daemon (which is very very basic i have to admit). Is there anything i may have overlooked which helps with the POP3 Performance, any patches that disable the unnecessary indexing etc.? If not, what do you guys recommend and use as a pop3 daemon that is fast and stable? I'm using dovecot 1.0.2 (i checked the ChangeLog, doesn't look like upgrading would give better pop3 performance?) and the relevant pop3-config is: mail_location: maildir:~/Maildir:INDEX=MEMORY mail_debug: yes dotlock_use_excl: yes maildir_copy_with_hardlinks: yes mail_executable: /usr/local/dovecot/libexec/dovecot/pop3 mail_plugin_dir: /usr/local/dovecot/lib/dovecot/pop3 pop3_enable_last: yes pop3_uidl_format: %f pop3_client_workarounds: outlook-no-nuls oe-ns-eoh Any hint in the right direction is greatly appreciated Regards, Sebastian Faerber

[Dovecot] Homedir permissions problems with LDAP
by "Fábio M. Catunda" 04 Jan '08

04 Jan '08

Sorry, my previous message entered like a reply, so I'm sending again to keep the list in order. Hi, I'm using dovecot 1.0.5-1 (debian stable) and I'm trying to build a virtual host machine with ldap. In my dovecot-ldap.conf thats what I have: uris = ldap://<ldapserver>/ dn = cn=Manager, dc=domain, dc=com, dc=br dnpass = <ultra secret passwd> sasl_bind = no tls = no ldap_version = 3 base = ou=Users, dc=domain, dc=com, dc=br deref = never scope = subtree user_attrs = homeDirectory=homeDirectory user_filter = (&(mail=%u)) pass_attrs = mail=user,userPassword=password pass_filter = (&(mail=%u)) default_pass_scheme = CRYPT user_global_uid = 107 user_global_gid = 109 But I don't want to read homeDirectory from LDAP, so I have the following in dovecot.conf mail_location = maildir:/var/virtual/%d/%n/ The question is when I try to log into imap I receive the following error: dovecot: 2008-01-03 10:03:55 Error: IMAP(magalhaes(a)fmcs.com.br): mkdir(/HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB/expunged/cur) failed: Permission denied dovecot: 2008-01-03 10:03:55 Error: IMAP(magalhaes(a)fmcs.com.br): mkdir(/HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB/deleted/cur) failed: Permission denied dovecot: 2008-01-03 10:03:55 Error: IMAP(magalhaes(a)fmcs.com.br): mkdir(/HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB/deleted/expunged/cur) failed: Permission denied (I'm using lazy_expunge too) I can log in and etc, but this is strange for me, why do I receive this Permission denied message? The directory /var/virtual/<domain>/<user>/ is owned by uid 107 and gid 109, so, i believe thats ok. My homedir in ldap is /home/samba/<user> , so I changed tried to chown 107:109 too but I still get this error. Is there a way for me to know what is the full path that dovecot is trying to use? HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB is no helping me too much! Oh, I imagine that my lazy_expunge conf may be helpfull: namespace private { prefix = .EXPUNGED/ separator = / location = maildir:~/expunged hidden = yes } namespace private { prefix = .DELETED/ separator = / location = maildir:~/deleted hidden = yes } namespace private { prefix = .DELETED/.EXPUNGED/ separator = / location = maildir:~/deleted/expunged hidden = yes } Thanks for all!

[Dovecot] Compile error introduced in b13 (Solaris 10)
by mikkel＠euro123.dk 04 Jan '08

04 Jan '08

Any news on the b13 compile issue on Solaris 10 (both Sparc and X86)? Would be nice to know whether it's our own headache or something thats not supposed to be and thus expected to be fixed in the next release. Just to be clear this didn't occur in any other release (I've compiled all previous v1.1 betas on the same setup including b12).

[Dovecot] latest 1.1 betas and quota warning
by arvids 03 Jan '08

03 Jan '08

Hello, I noticed that quota warning is not executed with latest 1.1 betas and I looked at the code that implements quota warning. Here it is (line 657 in quota.c): if ((bytes_current < warnings[i].bytes_limit && bytes_current >= warnings[i].bytes_limit) || (count_current < warnings[i].count_limit && count_current >= warnings[i].count_limit)) { quota_warning_execute(warnings[i].command); break; } It seems to me that quota_warning_execute function will never be executed. Timo, can you look at this code? Regards, Arvids

[Dovecot] Building path to maildir
by Michel Bulgado 03 Jan '08

03 Jan '08

I have the following situation and I need help from all you people I have dovecot 0.99.11 and i want to migrate to a superior version like dovecot 1.0 looking forward to implement quotas in my system , and use the function deliver with postfix. My Scenario is as follow Dovecot + LDAP (ADS) + postfix My actual version is : 0.99.11 This is my actual configuration: Protocols = imap pop3 imap_listen = * pop3_listen = * login_dir = /var/run/dovecot-login login = imap login = pop3 default_mail_env = maildir:/var/spool/virtualmail/%d/%n mbox_locks = fcntl auth = dovecot-auth auth_mechanisms = plain auth_default_realm = CASA.CULT.CU auth_userdb = ldap /etc/dovecot-ldap.conf auth_passdb = pam dovecot auth_user = root auth_verbose = yes auth_debug = yes dovecot-ldap.conf hosts = ldap.casa.cult.cu base = ou=CASA,dc=casa,dc=cult,dc=cu dn = cn=unix-conector,cn=Users,dc=casa,dc=cult,dc=cu dnpass = ***** ldap_version = 3 deref = never scope = subtree user_global_uid = 500 user_global_gid = 500 user_attrs = mail,/var/spool/virtualmail/%d/%n,,,, user_filter = (&(objectClass=user)(!(objectClass=computer))(sAMAccountName=%n)) I see many changes in this new version. One of them is : -Renamed default_mail_env to mail_location - many changes in ldap queries With the new version my problem is when to dovecot tries to detect or builds the way where it´s stored the mailbox of my users. In /var/spool/virtualmail/%d/%u , it does not detect the domain when asking to my active directory (w2k) and consequently takes a value of my default realm = casa.cult.cu in this case the default domain where authenticate my users. My configuration in the new version of dovecot: protocols = imap pop3 protocol imap { listen = * } protocol pop3 { listen = * } login_dir = /var/run/dovecot/login login_chroot = yes login_greeting = Dovecot ready. mail_location = maildir:/var/spool/virtualmail/%d/%u mail_debug = yes mbox_read_locks = fcntl mbox_write_locks = fcntl protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } protocol lda { postmaster_address = postmaster(a)example.com mail_plugins = quota auth_socket_path = /var/run/dovecot/auth-master } auth_executable = /usr/libexec/dovecot/dovecot-auth auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb pam { args = dovecot } userdb ldap { args = /etc/dovecot-ldap.conf } userdb prefetch { } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = virtualmail group = virtualmail } } } dict { } plugin { quota = maildir:storage=10240 } user_attrs = mail,/var/spool/virtualmail/%d/%n,,,, The attribute mail in the old version returns to me user(a)casa.com or user(a)casa.cult.cu this way dovecot can build the way with no problems at all. But in this late version something is happening, it only takes the value %n= user , but not %d = domain . It´s not working. do you have any idea how I can solve this I beg your pardon for my poor English. ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

[Dovecot] dovecot-auth consumes 100% CPU time on Solaris 10
by KOT MATPOCKuH 02 Jan '08

02 Jan '08

Is problem with CPU load solved? I have same problem - dovecot-auth eats one of my cores. I'm using dovecot 1.0.7 on Solaris 10 Sparc. I tried to use auth-bind and standard scheme with separate user for bind and have same result. Problem occupts only with LDAP authentication, on some other systems I use PostgreQSL and MySQL authentication and doesn't have this problem. Using PAM authentication is not possible, because dovecot run in chroot'ed environment and I planing to move it to separate system or zone without ldap client. -- MATPOCKuH

[Dovecot] Delay on failed pw attempts
by Dean Brooks 02 Jan '08

02 Jan '08

Hi, Is there a way, or can a way be added, to add an "auth_failed_delay=10s" style option that would put in an artificial delay after a failed password attempt? As it stands now, Dovecot seems highly vulnerable to widescale brute-force password dictionary scans. Even if it's not configurable, can a delay be hardcoded to something like, say, 10 or 15 seconds? -- Dean Brooks dean(a)iglou.com

[Dovecot] deliver triggering SELinux AVC denials
by Gerry Reno 02 Jan '08

02 Jan '08

I setup postfix/dovecot on a new machine and now all works well with the small exception of dovecot triggering selinux avc denials on some temp... files here is a sample alert: Summary SELinux is preventing /usr/libexec/dovecot/deliver (dovecot_deliver_t) "link" to temp.localhost.678.40caaf5592891c46 (user_home_dir_t). Detailed Description SELinux denied access requested by /usr/libexec/dovecot/deliver. It is not expected that this access is required by /usr/libexec/dovecot/deliver and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for temp.localhost.678.40caaf5592891c46, restorecon -v temp.localhost.678.40caaf5592891c46 If this does not work, there is currently no automatic way to allow this access. Instead, you can generate a local policy module to allow this access - see http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you can disable SELinux protection altogether.

[Dovecot] my.cnf reading support in MySQL backend
by Luca Longinotti 01 Jan '08

01 Jan '08

I hope this ml is the right place to send this... Anyway, I'd very much like for the MySQL backend to call mysql_options, so that it'll read the settings defined in MySQL's my.cnf under the [client] section. This allows to set a whole slew of MySQL specific settings for the MySQL connection, for example to enable the compressed protocol, set charsets, enable SSL client verification, and much more. A patch is attached that implements this. See http://dev.mysql.com/doc/refman/5.0/en/mysql-options.html for more info. -- Best regards, Luca Longinotti aka CHTEKK LongiTEKK Networks Admin: chtekk(a)longitekk.com Gentoo Dev: chtekk(a)gentoo.org SysCP Dev: chtekk(a)syscp.org TILUG Supporter: chtekk(a)tilug.ch

[Dovecot] deliver: keep existing From_ line
by Alexander 'Leo' Bergolth 01 Jan '08

01 Jan '08

Hi! I'm using procmail to filter my email. (I have to use it because of various features that are not supported by sieve.) However, I'd like to deliver mail to my mboxes using dovecots deliver program in order to update index files and speed up mbox access. Using "| $DELIVER -m <mboxname>" in my procmail receipes, everything works fine, except that the envelope sender address is mangled. deliver sets it to MAILER-DAEMON, even though it is already provided in the first line of the mail. I cannot use the "-f <address>" options of deliver, since procmail doesn't provide the envelope-sender address in a variable. (I'd have to extract it from the first line of the mail using a separate receipe, which isn't very efficient.) Is there a way to keep the already existing "From " line?

My configuration in the new version of dovecot: protocols = imap pop3 protocol imap { listen = * } protocol pop3 { listen = * } login_dir = /var/run/dovecot/login login_chroot = yes login_greeting = Dovecot ready. mail_location = maildir:/var/spool/virtualmail/%d/%u mail_debug = yes mbox_read_locks = fcntl mbox_write_locks = fcntl protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } protocol lda { postmaster_address = postmaster(a)example.com mail_plugins = quota auth_socket_path = /var/run/dovecot/auth-master } auth_executable = /usr/libexec/dovecot/dovecot-auth auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb pam { args = dovecot } userdb ldap { args = /etc/dovecot-ldap.conf } userdb prefetch { } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = virtualmail group = virtualmail } } } dict { } plugin { quota = maildir:storage=10240 } user_attrs = mail,/var/spool/virtualmail/%d/%n,,,, The attribute mail in the old version returns to me user(a)casa.com or user(a)casa.cult.cu this way dovecot can build the way with no problems at all. But in this late version something is happening, it only takes the value %n= user , but not %d = domain . It´s not working. do you have any idea how I can solve this I beg your pardon for my poor English. ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

[Dovecot] Maildir
by Peter Fraser 01 Jan '08

01 Jan '08

I have been trying to set up dovecot with postfix to use at work. I'm trying to configure dovecot to authenticate against active directory and postfix the same. I installed dovecot 1.0.10 on FreeBSD 7.0 beta 2 When I telnet in the get authentication ok but an error suggesting that there is no Mailbox belonging to that user. I am using Maildirs. How can I now create a Maildir with the proper permissions for that virtual user? Thanks for any assistance.

[Dovecot] Enhanced Kerberos support
by Richard A Nelson 31 Dec '07

31 Dec '07

The recent addition of auth_gssapi_hostname is a welcome addition, but a little more is needed for multi-homed (or multi-domained) sites. SSH recently added this enhancement to address this common need: GSSAPIStrictAcceptorCheck Determines whether to be strict about the identity of the GSSAPI acceptor a client authenticates against. If “yes” then the client must authenticate against the host service on the current hostname. If “no” then the client may authenticate against any service key stored in the machine’s default store. This facility is provided to assist with operation on multi homed machines. The default is “yes”. Note that this option applies only to protocol version 2 GSSAPI connections, and setting it to “no” may only work with recent Kerberos GSSAPI libraries. I've heard that other daemons support multi-names by instead of using gethostname(), obtain the hostname of the interface that the request came in on. Can either approach be looked at for dovecot ?

[Dovecot] Help with logging in and getting mail
by Andrew Falanga 31 Dec '07

31 Dec '07

Hi, Very new to dovecot and to using POP3/IMAP (from this perspective anyway). First things first, per the instructions from the web site: dovecot version: 1.0.5 dovecot config: # 1.0.5: /usr/local/etc/dovecot.conf protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login verbose_proctitle: yes first_valid_gid: 0 mail_extra_groups: mail mail_location: mbox:~/mail/:INBOX=/var/mail/%u mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain digest-md5 user: vmail passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf Please help me diagnose what is causing the following problem. Essentially, this user is a virtual user. I have it so that the system user, vmail, is the basket into which all virtual users e-mail goes. If my understanding is correct (and please enlighten me if it's not), mail aliases are setup to "map" aliased names into a real account. From there, dovecot will return e-mail to the virtual user based upon the "To" field of the e-mail, correct? I have some aliases in my sendmail config that do just this. From the error below, it would seem that dovecot is actually authenticating the virutual user "jdunkin" in this case, but can't get some directories made. I've seen on my FreeBSD system that each system user has a "mail" file in the directory, /var/mail/<userid>. What needs to be done further? Also, how do I ensure that virtual users are able to get their mail as well as system users?

[Dovecot] 1.1b13 build

After reading of the problems encountered on other systems, the 1.1 beta 13 version (main part as well as Deliver) seems to inexplicably be running just fine under OS X 10.5.1 for some reason. :^) Jerry

[Dovecot] Time just moved backwards
by Neal Becker 31 Dec '07

31 Dec '07

This wins the 2007 award for strangest (or most amusing) log message: dovecot: Time just moved backwards by 13 seconds. This might cause a lot of problems, so I'll just kill myself now. It does, unfortunately, leave dovecot dead, which was pretty mysterious to me. Maybe it could re-exec instead?

[Dovecot] donations / wishlist
by Timo Sirainen 31 Dec '07

Since some people don't like Paypal and other people have been telling me for years to create Amazon wishlist, I figured I'd finally do it. http://dovecot.org/donate.html now contains URL to the wishlist. Currently it mostly contains all kinds of TV series DVDs (feel free to laugh at what I watch :), but I also managed to remember a couple of books I wanted.

On F7, I get to where I have Postfix and Dovecot installed and configured, postfix check runs fine, but when I try to start Dovecot I'm getting a permission error. Here is the log entry: Dec 29 21:54:06 grp-01-50-90 dovecot: Dovecot v1.0.7 starting up Dec 29 21:54:06 grp-01-50-90 dovecot: Generating Diffie-Hellman parameters for the first time. This may take a while..

I forgot to mention that when I try to start Dovecot that I get this message: dovecot dead but subsys locked I'm thinking it is just a side effect of the permissions issue. Anyway I tried setting perms to 777 on /var/run/dovecot but this didn't help. So still needing some hints. A clue. I can start Dovecot as 'root': # dovecot # ps -ef root 14164 1 0 00:07 ? 00:00:00 dovecot root 14165 14164 0 00:07 ? 00:00:00 dovecot-auth root 14166 14164 0 00:07 ? 00:00:00 dovecot-auth -w dovecot 14168 14164 0 00:07 ? 00:00:00 pop3-login dovecot 14169 14164 0 00:07 ? 00:00:00 pop3-login dovecot 14170 14164 0 00:07 ? 00:00:00 pop3-login dovecot 14171 14164 0 00:07 ? 00:00:00 imap-login dovecot 14172 14164 0 00:07 ? 00:00:00 imap-login dovecot 14173 14164 0 00:07 ? 00:00:00 imap-login maillog: Dec 30 00:07:40 grp-01-50-90 dovecot: Dovecot v1.0.7 starting up Dec 30 00:07:41 grp-01-50-90 dovecot: auth-worker(default): mysql: Connected to 127.0.0.1 (mailserver) But if I try to start it using init.d: # service dovecot start dovecot dead but subsys locked maillog: Dec 30 00:12:49 grp-01-50-90 dovecot: Auth process died too early - shutting down Dec 30 00:12:49 grp-01-50-90 dovecot: auth(default): bind(/var/run/dovecot/auth-master) failed: Permission denied Dec 30 00:12:49 grp-01-50-90 dovecot: auth(default): net_listen_unix(/var/run/dovecot/auth-master) failed: Permission denied Dec 30 00:12:49 grp-01-50-90 dovecot: child 14301 (auth) returned error 89 ????

[Dovecot] building dovecot-sieve against installed dovecot
by Geert Hendrickx 30 Dec '07

30 Dec '07

Hi Timo, may I request once more to consider the attached patch for dovecot 1.1, it enables the sieve plugin (incl. sievec and sieved, needed for pysieved) to be built against an installed dovecot package, if --enable-header-install additionally installs the liblib.a library in the same directory as dovecot-config. I have included this patch in the pkgsrc dovecot 1.1 package a while ago. Geert

[Dovecot] global and per-users sieve filters
by Nikolay Shopik 29 Dec '07

29 Dec '07

Hi Timo, I'm curious about such thing, currently if user have their own filter global filter no more take a place. Is this behavior changed in 1.1 or maybe in future? I'm unsure if this is 100 sieve related or more like Dovecot handling so fixing can be easily can done.

[Dovecot] v1.0.10 released
by Timo Sirainen 29 Dec '07

29 Dec '07

http://dovecot.org/releases/1.0/dovecot-1.0.10.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.10.tar.gz.sig v1.0.8 and v1.0.9 were a bit bad releases. Hopefully one day I've managed to have written a proper test suite which can be run before doing any releases.. * Security hole with LDAP+auth cache: If base setting contained %variables they weren't included in auth cache key, which broke caching. This could have caused different users with same passwords to log in as each other. - LDAP: Fixed potential infinite looping when connection to LDAP server was lost and there were queued requests. - mbox: More changes to fix problems caused by v1.0.8 and v1.0.9. - Maildir: Fixed a UIDLIST_IS_LOCKED() assert-crash in some conditions (caused by changes in v1.0.9) - If protocols=none, don't require imap executables to exist

[Dovecot] How to logoff a session with dovecot?
by Robin Atwood 29 Dec '07

29 Dec '07

I use dovecot to push email to my SE P1i and it works very well. :) However, I have two email accounts set up on the phone, one using my domain for GPRS and public WiFi and one using my WLAN address for use at home, the idea being I don't want to pay for GPRS data at home. The trouble is the GPRS account remains logged on and I get the mail in both inboxes. There is no option in the email client on the phone to disconnect, so is there any trick to forcing a disconnect from the mail server?

[Dovecot] Fishing attempt locking up dovecot
by Patrick Milvich 29 Dec '07

29 Dec '07

I've mentioned this before but only heard from one other person who has experienced this, but it's becoming a pretty serious issue. The situation: A spammer sets a bot on a fishing attempt to gain email addresses, causing numerous login processes to spawn and suck up all available resources. The problem: Obviously this can act like a dos attack, but the real issue is after the spammer stops (by virtue of being added to our firewall blacklist, being caught and shut down by their isp, or otherwise), dovecot doesn't seem to relinquish the resources, causing "too many files open" errors for normal usage. The master process usually hangs around 40-50 files open at any given time, with about 10,000 logins a day (I use: lsof -p `cat /var/run/ dovecot/master.pid ` | wc -l), after the attempt is over I always see the files open shoot up to near 3,000 without it able to go down until a dovecot restart. This usually happens about once a month, though we can get unlucky and have it happen a few days apart. I have some log excerpts below. Wondering if this is happening through my own fault or at least within my ability to alleviate the issue. Is there a way to limit the number of connections from an ip address? Has anyone used login_executable to first hit their own solution to keep track of, and implement connection restrictions similar to what I'm aiming for?

[Dovecot] v1.1.beta11 released
by Timo Sirainen 29 Dec '07

29 Dec '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta11.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta11.tar.gz.sig This one should be the last beta release before the first v1.1 release candidate. I'll try to stay away from this list and Dovecot in general for the next 1,5 weeks. I've several exams coming up and I should have started studying for them days ago already.. :) The main things left in my TODO are: - Squat indexes should handle expunges - Lucene indexes are broken - See if \recent flag handling could be fixed for maildir/mbox (it works for dbox though) - Some other minor things which I'll do if I have time, but won't block v1.1.0 release. Changes since beta10: - One major performance issue found and fixed. This was the main reason why we weren't yet in release candidate stage. - configure --with-package now gives an error if it can't find the necessary libs/headers for the package. Use --with-package=auto for the old behavior. - Memory leak fixes - Convert plugin fixes. Conversion is now done to namespace with INBOX. - Changes to handling group adding/removing to processes. Hopefully didn't break anything. - Message flag/keyword searches are now faster - Fixes/optimizations to handling SORT. After building initial indexes, my 260k mail mailbox sorts in about 0.01 seconds. :) - Fixes to searching mails with unknown charsets/invalid data - deliver_log_format setting

[Dovecot] auth-ldap not resetting connection state after failed bind
by Brendan Braybrook 29 Dec '07

29 Dec '07

timo, i think i found a small problem with the ldap implementation: when using auth_bind (this might be in all conditions, not just that one - i haven't tested further), if the server lost connection to the ldap server (ie, the ldap server died) dovecot-auth would never reconnect to the ldap server and all subsequent auth attempts would fail. after a little more digging, i discovered that if the ldap server went down and came back up before the next dovecot request then everything would be fine. however, if a request came in while the ldap server was down then dovecot-auth would "cache" that the server was unavailable and never recheck it. i believe i tracked it down to a couple lines in db_ldap_bind and fixed it - dovecot-auth is reconnecting to ldap in the condition where it was not previously: --- dovecot-1.0.3/src/auth/db-ldap.c 2007-10-15 18:26:55.983349000 +0000 +++ dovecot-1.0.3/src/auth/db-ldap.c.new 2007-10-15 18:28:03.124136000 +0000 @@ -446,7 +446,10 @@ msgid = ldap_bind(conn->ld, conn->set.dn, conn->set.dnpass, LDAP_AUTH_SIMPLE); if (msgid == -1) { - db_ldap_connect_finish(conn, ldap_get_errno(conn)); + if (db_ldap_connect_finish(conn, ldap_get_errno(conn)) < 0) { + /* lost connection, close it */ + ldap_conn_close(conn, TRUE); + } i_free(ldap_request); return -1; }

[Dovecot] dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server
by Rolf E. Sonneveld 28 Dec '07

28 Dec '07

Hi, I'm new to the list; excuse me if this has been asked recently/before. running: # dovecot --version 1.0.8 Output of dovecot -n: base_dir: /var/run/dovecot protocols: none ssl_disable: yes login_dir: /var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/imap-login auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: ldap args: /usr/local/dovecot/etc/dovecot-ldap.conf userdb: driver: ldap args: /usr/local/dovecot/etc/dovecot-ldap.conf socket: type: listen client: path: /usr/local/postfix/spool/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot-auth-master mode: 438 Using dovecot only for the purpose of providing SMTP AUTH service for Postfix, using Active Directory (AD) as authentication source. As you can see from the config, connectivity between Dovecot and AD is implemented using LDAP. Contents of /usr/local/dovecot/etc/dovecot-ldap.conf (some site-specific info masqueraded): auth_bind = yes pass_filter = (sAMAccountName=%u) hosts = AD1.domain.com:3268 AD2.domain.com:3268 dn = CN=Service Account Postfix,OU=Services,DC=domain,DC=com dnpass = secret ldap_version = 3 base = DC=domain,DC=com scope = subtree Now, this works fine and authentication via SMTP AUTH + Dovecot works perfect. Yet, every 15 minutes I get the following warning in the syslog logfile: Dec 24 07:20:00 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server Dec 24 07:35:01 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server Dec 24 07:50:01 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server Dec 24 08:05:02 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server Dec 24 08:20:02 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server Dec 24 08:35:03 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server I've looked through the archives and it seems that this problem is caused by the fact that Dovecot (using the OpenLDAP client libraries?) keeps the LDAP connection open; after (in our case) 15 minutes Active Directory closes the connection and Dovecot signals this in the syslog (and presumably automatically will create a new connection to AD). I'm pretty sure that the OpenLDAP client libraries provide options to use a client-side timeout for LDAP connections. My questions are: * is there a reason that Dovecot wants to keep the LDAP connection open? * Will the new V1.1 version have a config parameter to set the LDAP client timeout or a default timeout value to close the connection? * If there's no 'fix' foreseen for V1.1, I'd like to file a request to add such a parameter. How can I file such a request? The warning is annoying; the sysadmin will create a filter, to filter the warning out from the syslog, but I'm afraid that if there's a real problem with authentication, that will be filtered too and the real problem is not noticed, before users start to complain. /rolf

Escape character is '^]'. * OK [CAPABILITY IMAP4 IMAP4rev1 LITERAL+ ID STARTTLS AUTH=CRAM-MD5 AUTH=DIGEST-MD5 AUTH=NTLM AUTH=SRP AUTH=OTP AUTH=PASSDSS-3DES-1 SASL-IR] Cyrus IMAP4 v2.3.8 server ready 1 login ... 1 OK [CAPABILITY IMAP4 IMAP4rev1 LITERAL+ ID LOGINDISABLED ACL RIGHTS=kxte QUOTA MAILBOX-REFERRALS NAMESPACE UIDPLUS NO_ATOMIC_RENAME UNSELECT CHILDREN MULTIAPPEND BINARY SORT SORT=MODSEQ THREAD=ORDEREDSUBJECT THREAD=REFERENCES ANNOTATEMORE CATENATE CONDSTORE IDLE LISTEXT LIST-SUBSCRIBED X-NETSCAPE URLAUTH] User logged in 2 NAMESPACE * NAMESPACE (("INBOX/" "/")) (("user/" "/")) (("" "/")) 2 OK Completed 3 logout * BYE LOGOUT received ---snip--- So Dovecot is stating Namespace separator is ".". But my dovecot -n namespace section shows: namespace: type: private separator: / prefix: INBOX/ inbox: yes list: yes subscriptions: yes According to this I've set separator to "/". And this is the problem. I think problem arised somewhere between beta9 and beta11, as it worked before... The separator in imapsync was for both "/" (--sep1 /, --sep2 /), I just played with all possibilities... Well, never mind if v1.2 or v2.0, as long as LMTP makes it in ;) Anyway, we can provide some good stress testing in such an environment... Regards and for all Merry Christmas and a happy new year!

Forwarding all mail to a SMTP server on the machine running dovecot and doing delivery there isn't the favoured option (at least for us). Yes, LMTP would be nice, but it pretty much requires v2.0 framework. I'm still not sure if the next version will be v1.2 or v2.0.. Jetzt Mails schnell in einem Vorschaufenster überfliegen.

[Dovecot] assertion on deliver (1.1.beta10)
by Nuno Lopes 28 Dec '07

28 Dec '07

Hi, I'm testing version 1.1.beta10 and getting these assertions on deliver: file index-transaction.c: line 54 (index_transaction_finish_rollback): assertion failed: (t->mail_ref_count == 0) This was after an upgrade from a 1.0 release candidate. If you need I can try and reproduce this in a more controled environment to pinpoint the problem. Thanks, -- Nuno Lopes

[Dovecot] Dovecot + Cygwin the 2nd
by Ronny 28 Dec '07

28 Dec '07

Hi, i still try to get dovecot to run under cygwin. After a post on the cygwin list i am able tu run dovecot. Under Cygwin you have to run dovecot by inetd. Starting the binary "dovecot.exe" does not work. Well the server is running but answers with a fatal error. Account: 'localhost', Server: 'localhost', Protokoll: POP3, Serveranswer: 'Fatal: EOF while reading environment from master', Port: 110, Secure (SSL): No, error on server: 0x800CCC90, Fehlernummer: 0x800CCC90 This error is from Outlook, Thunderbird just says there is an error without any error message. So maybe you can help me to bring my story to a hapy end ;-) Cheers Ronny

[Dovecot] cache files corruption

[Dovecot] v1.1.beta12 released
by Timo Sirainen 25 Dec '07

25 Dec '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta12.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta12.tar.gz.sig Still not a release candidate, maybe the next one.. This release fixes a lot of bugs and adds some new sanity checks. Fixes quite a lot of mbox problems. v1.1.beta11 (no other versions) had a potential security hole where memory was free()d multiple times. \Recent flags should work perfectly now with mbox. Still somewhat broken with maildir.
