You'd need to find out what exactly is locking those mailboxes for that long. It could simply be the user's client. Or I guess it could be LDA itself, or anything really.. Difficult to say. Difficult also to tell easy way to debug this.. Or when this happens does it happen to many people at the same time? Is the system load really high at that time then?

[Dovecot] Login via IMAP with MySQL as user database not working
by Chris Martin 13 Apr '11

13 Apr '11

Hello all, I am migrating from Postfix/Cyrus/MySQL mail server to a recently installed dovecot 1.2.8 on a QNAP TS259 NAS via XDove. I am unable to login via IMAP (the only method I've tried and the only method I want). I am using an almost identical database as the current existing Postfix/Cyrus/MySQL setup (with the except of paths). I have been attempting to get this working (off and on) for the past 5 months. During that time I have researched and researched, but have not found a solution. The Maildir has been copied from the existing server to the Dovecot server and have run the script 'courier-dovecot-migrate.pl', which was found at http://www.dovecot.org/tools/courier-dovecot-migrate.pl In a nutshell: If I have the password_query string in the SQL config file (shown below) set to return only 1 field, i.e. the password, then the Dovecot authtest app succeeds. But if more than 1 field is returned (i.e.: user and password) the test fails. And if testing with telnet I get the message of "* BYE Internal login failure. Refer to server log for more information.". The logs indicate that the password check returned OK but the userdb read appears to fail. If I change the userdb_query to return only 1 field (such as only the uid), then the logs show the correct value is returned, and yet the telnet login fails. So it seems that anytime there are multiple fields returned from the SQL query, the result is failure at that step (password check or userdb read). Therefore userdb prefetch never works. The NAS doesn't utilize a syslog so it's of no help in debugging. Below are the config files and samples from log files (scrubbed): dovecot.conf- (NOTE: the 'home = /tmp' in the plugin section is an attempt at rawlog from http://wiki2.dovecot.org/Debugging/Rawlog ... which doesn't seem to work) # 1.2.8: /etc/dovecot/dovecot.conf # OS: Linux 2.6.33.2 i686 log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot-info.log log_timestamp:

[Dovecot] Solaris 10 Compilation Issue with 2.0.12 (actually post 12690) [WORKAROUND PROVIDED]
by Peter Bray 13 Apr '11

13 Apr '11

Greetings, Post 12689:7f5735ab7c35 / 12690:02829f7f79c7 dovecot uses the reentrant version of get(password/group)* related functions. There are two variants of these functions on Solaris. To get the variant used by dovecot code based you need to define _POSIX_PTHREAD_SEMANTICS (see attached manual page). Initially I defined this just for the compilation of lib/src/ipwd.c, and got the code to compile / check / run successfully in my environment. After this worked I decided to try compiling the whole code base with CPPFLAGS="-D_POSIX_PTHREAD_SEMANTICS" ./configure .... This also seems to work fine. My environment uses IMAPS (X86) and Proxying IMAPS (SPARC). All code compiles / checks / runs (only 64-bit versions run tested) with the above CPPFLAGS modification on Oracle Solaris 10 Update 9 (both 32/64 bit on both X86 / SPARC with GCC 4.1.2) systems. Regards, Peter Bray Sydney, Australia PS: I have not investigated an appropriate way to modified configure.in to make this addition automatic.

Multiple > deliveries are useful only if you want to try to get the same mail file > hard linked to all recipients. So normally this is a non-issue. I guess my sendmail is not normal. The default configuration does pool multiple recipient delivery and run mail.local with all these users as arguments in one invocation. dovecot-lda doesn't seem to support multiple recipients per invocation, so this won't be a problem. The implication for sendmail users, though, is that multiple concurrent deliveries must be disabled if you use dovecot-lda (the 'm' flag must be removed from LOCAL_MAILER_FLAGS) as implicitely done in http://wiki2.dovecot.org/LDA/Sendmail I notice the 'A' flag is missing here: doesn't this kill aliasing?

[Dovecot] Best practices to migrate from mbox to Maildir++ and also changing the deliver method
by Julio C. Ortega 13 Apr '11

13 Apr '11

Greetings. Im about to move from mbox to Maildir++ and change the deliver method from procmail. I have less than 100 accounts, but there's a lot of mail (around 16GB) Apart from the documentation on Dovecot's site, anyone has good recommendations, and, if you have experience doing this migration any tips? Thanks for any info, and wishing you all a nice week -- ------------------------------------ Julio C. Ortega ONUVA http://www.onuva.com

[Dovecot] Upgraded to Dovecot-1.2.16 and Sieve-1.1.8 but Still No Sieve Parameters
by Jay Welch 12 Apr '11

12 Apr '11

I have upgraded to a newer version of Dovecot and I have installed Sieve. Everything went smooth and with no errors but I still don't see any Sieve parameters in dovecot.conf file. I'm looking at /usr/local/etc/dovecot-example.conf. What could be the issue? Thanks -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] Questions about converting maildir to mdbox.
by Henrique Fernandes 12 Apr '11

12 Apr '11

First of all i would like to thanks Timo for the excellent job done in dovecot. We are using it in you prodution server with about 5 millions of emails and it is pretty good, only a performance problens but i guess it is realated to ocfs2 that we are using. So lets begin: We are using dovecot 2.0.6 with maildir in an ocfs2 partiton. It is pretty slow access in peak time, but it is related to ocfs2 as i said before, i am trying to mimimize the ocfs2 latancy by using mdbox. Another problem that we have are Full backup that takes about 24h and incremental takes about 13h I am thinking in converting some email for testing propose, but i am wondoring how would dovecot convert this, like if i convert all mail from maildir to mdbox it would make many mailbox based on this seetings ? Or in the first convert it would make a big mdbox file and after it it will rotate by day or it would make many boxes just based on size? mdbox_rotate_size = 5m mdbox_rotate_interval = 1d Well, another thing can i make rotate interval happens in a certain time of day? end from where it takes this time ? it rotates at midnight ? Another one!, if i lose the index files what really happens ? Sometimes in my server the index get corrupet and as i am reading mdbox index files held information that is not in other place. So what should i do to prevent any possible lose of data even if i lose the indexes? I was reading about backup restore also, but i did not get it pretty well. With maildir we simple restore the files and the index gets rebuilt! What should i do with mdbox ? Restore the files and the index ? But how about the other emails that the account got after the backup, how i should merge the multiple files and more importanet how do i merge the index files ? Well, sorry about my english! And Thanks alot guys! []'sf.rique

[Dovecot] Vpopmail and lastauth
by mailing＠securitylabs.it 12 Apr '11

12 Apr '11

Hello, I'm migrating many accounts to a new server with vpopmail 5.4.33 and dovecot 2.0.11. I've already vpopmail 5.4.32 and dovecot 1.2.16 on others servers running without problems. With dovecot 2.0.11 my lastauth file is not updated. This file usually is update on any access (smtp, pop3, imap) with the client's IP, for every mailbox. Now it's updated only when a client authenticate itself via SMTP (smtp-auth with qmail + vpopmail), and not with imap/pop3 access. My conf: # 2.0.11: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.1 auth_cache_negative_ttl = 2 mins auth_cache_size = 1000 M auth_cache_ttl = 2 mins auth_mechanisms = plain cram-md5 apop auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@& disable_plaintext_auth = no first_valid_uid = 89 last_valid_uid = 95 lock_method = dotlock log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = Server ready. mail_fsync = never mail_gid = vchkpw mail_location = maildir:~/Maildir mail_privileged_group = vchkpw mail_uid = vpopmail namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = webmail=127.0.0.1 driver = vpopmail } plugin/mail_log_events = delete expunge plugin/mail_log_group_events = plugin/quota = maildir plugin/quota_rule = ?:storage=0 pop3_uidl_format = %f protocols = imap pop3 service auth { unix_listener auth-userdb { group = vchkpw mode = 0600 user = vpopmail } } service imap-login { client_limit = 256 process_limit = 128 process_min_avail = 3 service_count = 1 } service imap { drop_priv_before_exec = yes process_limit = 256 vsz_limit = 256 M } service pop3-login { client_limit = 256 process_limit = 128 process_min_avail = 3 service_count = 1 } service pop3 { drop_priv_before_exec = yes process_limit = 256 vsz_limit = 256 M } ssl_cert = </usr/local/etc/dovecot/dovecot.crt ssl_key = </usr/local/etc/dovecot/dovecot.key userdb { args = quota_template=quota_rule=*:backend=%q driver = vpopmail } protocol imap { mail_max_userip_connections = 10 mail_plugins = " notify quota imap_quota mail_log" }

[Dovecot] SUMMARY: LDA vs LMTP, Cyrus SASL, verbose_proctitle
by Joseph Tam 12 Apr '11

12 Apr '11

A summary of answers I got to the questiosn I posed. > Is there a reason I should prefer LMTP over LDA for local delivery? Thanks for the responses I received. The benefits reported were more/better information logging, and service isolation. Also, one significant advantage not mentioned for LMTP was that one delivery failure to multiple recipients can be disambiguated; LDA can only return an exit code to be tested by the MTA, but the MTA cannot know which recipient(s) generated the error. This problem present can itself, for example, when one user has a full mailbox. An LDA will return EX_TEMPFAIL, and the message will be requeued, and delivery will be retried for all recipients (even those that were successfully delivered to). > The Wiki doesn't differentiates LMTP vs LDA with respect to sendmail > configuration, so am I correct that I just need to replace mail.local > with dovecot-lda, which will choose LDA/LMTP based on dovecot.conf? Not that simple, but I finally did find my answer in the Dovecot archives. It's too bad I had to spend hours tearing apart the sendmail docs before finding it http://www.dovecot.org/list/dovecot/2010-September/052936.html The .mc version of the configuration: # Use LMTP for local delivery over IPC channel FEATURE(`local_lmtp',`[IPC]') # Location of LMTP socket define(`LOCAL_MAILER_ARGS', `FILE /path/to/dovecot/lmtp') # Replace default sendmail LMTP options: the same options # with the 'P' flag removed so that the Return-Path is not # added (again?) define(`LOCAL_MAILER_FLAGS', `SXmnz9') MAILER(`local') I haven't tried this yet, but this is pretty close. > Also, can I consolidate authentication by configuring dovecot to use > what sendmail uses (Cyrus SASL) or vice versa? The Wiki hints this is > in the works. No response, so I guess the answer is no. > Lastly, toggling verbose_proctitle seems to have no effect on the output > of ps. Is verbose_proctitle broken for Solaris? The answer to is verbose_proctitle is broken for Solaris. There is no setproctitle(), and ps does not report changes to a process's argv[]: echo "main(int c,char**v){**v='x';sleep(9);}" | \ gcc -xc -o y -; ./y; rm y & ps -f You'll have to use "lsof", "pfiles" or "doveadm who" to get the information.

[Dovecot] Intermitent ldap auth problems benchmarking dovecot

Hello We are using SLAMD (Distributed Load Generation Engine, www.slamd.com) to benchmark our dovecot server (ldap auth). We are simulating 2.000 simultaneous logins and 20% of them fail. We saw the following errors in the log: Apr 12 09:40:07 buzon dovecot: auth: Error: ldap(correo,192.168.4.153): Request queue is full (oldest added 1 secs ago) Apr 12 09:40:07 buzon dovecot: auth: Error: ldap(correo,192.168.4.153): Request queue is full (oldest added 1 secs ago) Apr 12 09:40:07 buzon dovecot: auth: Error: ldap(correo,192.168.4.153): Request queue is full (oldest added 1 secs ago) We increased auth_worker_max_count from 350 to 3500 (10x increase).

[Dovecot] trying to combine static userdb with LDAP passdb with per-user userdb_mail and userdb_home
by Igor Zinovik 12 Apr '11

12 Apr '11

Hello, dovecot users. I'm trying to cope with following problem I have single computer which will be going to be final destination for several virtual domains. Domains are stored in LDAP catalog. Dovecot will be working together with Postfix MTA running on same computer. I'm a bit confused how to achieve following thing: I want Postfix to use Dovecot LMTP server for mail delivery. All my mail is located under /var/vmail partition. I designed my own ldap schema and according to dovecot documentation that user should always has home and mail directory i added separate attributes for user home and mail. My typical user that is stored in LDAP has homeDirectory (which stores value like /var/vmail/domain.com/j/joe) and mailMessageStore (which stores value like /var/vmail/domain.com/j/joe/Maildir). All data under /var/vmail is owned by Postfix MTA user (which is called `postfix', uid=89). After reading dovecot documentation I understand that my setup needs to combine static userdb with LDAP passdb. But i also want dovecot to be able to deliver mail for local system users (that are stored in /etc/passwd). For system users i want to store their mail in $HOME/Mail. So i set mail_location = ~/Mail (which turns into /home/user/Mail), but for virtual (which are stored in LDAP) users i want to set mail (or maybe i should write here userdb_mail) to LDAP value mailMessageStore. Seems to me that LMTP server needs separate userdb query to fetch mail_location from LDAP. Setting mail_location = /var/vmail/%d/%n1/%u solves my problem, but I want dovecot to dynamically fetch maildir location from LDAP. Maybe in near future I would also store mail somewhere else not only under /var/vmail. And dovecot will fetch this information from LDAP. Here is excerpt from dovecot log when user tries to login: Apr 11 13:32:29 auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Apr 11 13:32:29 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Apr 11 13:32:29 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so Apr 11 13:32:29 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_pgsql.so Apr 11 13:32:29 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Apr 11 13:32:29 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libmech_gssapi.so Apr 11 13:32:29 auth: Debug: auth client connected (pid=14748) Apr 11 13:32:29 auth: Debug: client in: AUTH 1 PLAIN service=imap lip=172.20.21.26 rip=172.20.20.216 lport=143 rport=1227 resp=<hidden> Apr 11 13:32:29 auth: Debug: ldap(joe(a)domain.com,172.20.20.216): pass search: base=pdomain=domain.com,ou=mail,dc=org,dc=ru scope=onelevel filter=(&(objectClass=mailAccount)(uid=joe)(accountStatus=TRUE)) fields=mail,userPassword,mailQuota,homeDirectory,mailMessageStore Apr 11 13:32:29 auth: Debug: ldap(joe(a)domain.com,172.20.20.216): result: mail(user)=joe(a)domain.com mailQuota(userdb_quota_rule=*:bytes=%$)=1073741824 mailMessageStore(userdb_mail)=/var/vmail/domain.com/p/joe/Maildir homeDirectory(userdb_home)=/var/vmail/domain.com/p/joe userPassword(password)=<hidden> Apr 11 13:32:29 auth: Debug: client out: OK 1 user=joe(a)domain.com Apr 11 13:32:29 auth: Debug: master in: REQUEST 2814377985 14748 1 5e00190b4fbfd1a4b8a50e13fa6562b1 Apr 11 13:32:29 auth: Debug: master out: USER 2814377985 joe(a)domain.com uid=89 gid=89 Apr 11 13:32:29 imap-login: Info: Login: user=<joe(a)domain.com>, method=PLAIN, rip=172.20.20.216, lip=172.20.21.26, mpid=14750 Apr 11 13:32:29 imap: Debug: Loading modules from directory: /usr/lib64/dovecot Apr 11 13:32:29 imap: Debug: Module loaded: /usr/lib64/dovecot/lib10_quota_plugin.so Apr 11 13:32:29 imap: Debug: Module loaded: /usr/lib64/dovecot/lib11_imap_quota_plugin.so Apr 11 13:32:29 imap: Debug: Module loaded: /usr/lib64/dovecot/lib11_trash_plugin.so Apr 11 13:32:29 imap: Debug: Module loaded: /usr/lib64/dovecot/lib20_autocreate_plugin.so Apr 11 13:32:29 imap: Debug: Module loaded: /usr/lib64/dovecot/lib20_expire_plugin.so Apr 11 13:32:29 imap(joe(a)domain.com): Debug: Effective uid=89, gid=89, home= Apr 11 13:32:29 imap(joe(a)domain.com): Debug: Quota root: name=User quota backend=maildir args= Apr 11 13:32:29 imap(joe(a)domain.com): Debug: Quota rule: root=User quota mailbox=* bytes=1073741824 messages=0 Apr 11 13:32:29 imap(joe(a)domain.com): Debug: Quota warning: bytes=1020054732 (95%) messages=0 reverse=no command=/usr/libexec/dovecot/quota-warning.sh 95 joe(a)domain.com domain.com Apr 11 13:32:29 imap(joe(a)domain.com): Debug: Quota warning: bytes=966367641 (90%) messages=0 reverse=no command=/usr/libexec/dovecot/quota-warning.sh 90 joe(a)domain.com domain.com Apr 11 13:32:29 imap(joe(a)domain.com): Debug: Quota warning: bytes=858993459 (80%) messages=0 reverse=no command=/usr/libexec/dovecot/quota-warning.sh 80 joe(a)domain.com domain.com Apr 11 13:32:29 imap(joe(a)domain.com): Error: user joe(a)domain.com: Initialization failed: Initializing mail storage from mail_location setting failed: Home directory not set for user.

Should i just add two attributes to each LDAP user like mailuid and mailgid and set both these variables to `postfix'. Or maybe i should just forget about mail for local system users and just user `prefetch' userdb. I'm just mazed about dovecot userdb and passdb queries. It so powerful but also so hard to understand. I would appreciate any help, since I peck dovecot authentication and userdb-passdb queries like woodpecker starting from last week. Do I understand right that dovecot during userdb fetches Unix UID which will be used to access data on disk? I just want postfix (uid=89) to allow to do this.

Re: [Dovecot] IO rate quotas?
by Alan Brown 12 Apr '11

12 Apr '11

From: Timo Sirainen <tss(a)iki.fi> Subject: Re: [Dovecot] IO rate quotas? > So a single process that is reading files fast enough from disk can > cause disk IO to spike in a way that makes all other processes wait for > available disk IO? It's not a single process. Thunderbird's newest defaults are to syncronize every folder and it will open one connectrion per folder in order to do that. Appropriate disk/swappiness/readahead/cache tuning is required - along with enough ram to cope with several users trying this at once. The underlaying filesystem is also important. as a for-instance, this kind of load with maildir format will effectively _kill_ a GFS box. Our fix was to install systemwide defaults on managed systems to not synchronize (not needed, the home directories are on network storage anyway) and to ask people to check/unset this on laptops/etc

[Dovecot] domain variable still empty

Hello all, First, thanks for your help with my previous NFS problem. I am trying to mount a mail server, with debian and dovecot 1.2.

[Dovecot] INBOX empty after dsync
by Gary Chodos 11 Apr '11

11 Apr '11

After hearing so many good things about mdbox, I am testing it. I moved my Maildir to a test box, and did the conversion with dsync which reported no errors and appeared to go fine after I set: namespace { separator = / inbox = yes } and changed mail_location=mdbox:~/mdbox But the problem is that the Inbox now is empty in my imap client. What did I do wrong? I can see the emails are there if I grep for subject lines I know exist in my inbox within ~/mdbox, but in the imap client it is as if inbox is totally empty. All the other folders appear fine in imap client.

[Dovecot] Dovecot 2.0 config bug with SSL certificate per protocol?
by Andy Smith 09 Apr '11

09 Apr '11

Hi, yesterday I upgraded Dovecot from 1.2 to 2.0.11. I'd seen that there was a config file converter to make the upgrade smooth so was expecting it to be pretty quick and easy. In the end I spent a long time trying to get it working as it just wouldn't listen on the ssl ports, imaps and pop3s. I am using per portocol SSL certificates, as I was in version 1.2. The part of my config is as follows (as generated by doveconf): protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep mail_plugins = fts fts_squat ssl = yes ssl_cert = </usr/local/etc/ssl.crt/imap.crt ssl_key = </usr/local/etc/ssl.key/imap.key } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv ssl = yes ssl_cert = </usr/local/etc/ssl.crt/pop3.crt ssl_key = </usr/local/etc/ssl.key/pop3.key } But when I started dovecot it was only listening on the non SSL ports for IMAP and POP3. I went through many things, adding in a service imap-login section with the SSL port set via inet_listener and spent ages googling for how to get it to work. In the end it turns out it was that the global ssl setting was set to "no", but I hadn't enabled this previously as this requires that there are global SSL certificates, which I don't have; I have specific certs for IMAP and for POP3. Also this isn't how dovecot 1.2 worked, there I specificed the protocols (pop3, pop3s, imap, imaps) and specificed the protocol certs and it worked. Anyway, I ended up just specifiing my pop3 certs as the global certs, this is then redefined in the pop3 protcol section etc. The config seems to work, but to me all this doesn't seem logical and doesn't work like in dovecot 1.2. Maybe this is something that can be cleaned up in the next version? thanks Andy.

[Dovecot] IO rate quotas?
by Kádár Tamás (KTamas) 09 Apr '11

09 Apr '11

Hi Okay so we've been having this issue since forever and I figured why the heck not ask it here since it's mostly related to dovecot. The thing is, we have a huge amount of public folders (at the moment, around 1100). Now, with dovecot indexing and caching we're mostly okay, also being careful with things like Thunderbird 3's default 'Download everything' option ("Keep messages for this account on this computer") and such. However once in a while, someone goes rogue, we install a new version of thunderbird, someone accidentally sets up an email account in thunderbird mistakingly leaving the download everything option on. This causes high IO on our server, and a single user can quickly more or less kill the whole server in mere minutes, load average quickly spiking to 30-40-50 and everything becomes sloooooow (obviously). Is there any way I can limit the amount of IO a certain user can use? Thanks and best regards, KT P.S. my dovecot -n is: # 2.0.9: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-xen-amd64 x86_64 Debian 5.0.8 auth_mechanisms = plain login disable_plaintext_auth = no listen = * mail_location = maildir:~/Maildir mail_plugins = acl maildir_very_dirty_syncs = yes namespace { inbox = yes location = prefix = separator = . type = private } namespace { location = maildir:/home/_shared/projects:INDEX=~/Maildir/_shared prefix = shared. separator = . subscriptions = no type = public } namespace { location = maildir:/home/_shared/sys:INDEX=~/Maildir/sys prefix = sys. separator = . subscriptions = no type = public } passdb { driver = pam } plugin { acl = vfile mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change append mail_log_fields = uid box msgid from subject size vsize flags mail_log_group_events = no } protocols = imap pop3 service imap { executable = imap } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 40 mail_plugins = acl imap_acl }

[Dovecot] Imap segfault on login with version 2.0.8 & 2.0.11
by Nicholas VonHollen 09 Apr '11

09 Apr '11

Hi everyone, I'm trying to upgrade/test our configuration files from Dovecot 1.2 to 2.0.11. I used the Dovecot config convert command, created a RHEL 5 x86_64 rpm, and tested it. I can connect, but once I login, the IMAP service segfaults. I've also reproduced this on version 2.0.8. I installed the debug RPM (for the stripped symbols), took a look at the core dump in gdb, and just got the _start method in ld_preload and a broken pointer in the backtrace. I tried to strace everything but the segfault doesn't happen then :-). I'm not sure what to do to get better information. I attached my client session, dovecot -n output, gdb trace, maillog, and the core dump. I published the RPMs I made at: http://c3205012.r12.cf0.rackcdn.com/dovecot-2.0.11-1_125.x86_64.rpm http://c3205012.r12.cf0.rackcdn.com/dovecot-debuginfo-2.0.11-1_125.x86_64.r… My platform is RHEL 5 with kernel 2.6.18 on x86_64. Is there anything else I can provide for more info? Thanks, Nick Nick VonHollen Rackspace Software Developer Desk: 540-443-2003 (internal 505-2003) Personal Cell: 757-710-7038

[Dovecot] restarting director
by Cor Bosman 08 Apr '11

08 Apr '11

Hi all, anyone having any problems with restarting the director? Every time I bring down 1 of the director servers, reboot it, or just restart it for whatever reason, im seeing all kinds of problems. Dovecot generally always gives me this error: Jan 20 22:49:55 imapdirector3 dovecot: director: Error: Director 194.109.26.173:444/right disconnected before handshake finished It seems the directors cant agree on forming a ring anymore, and this may be leading to problems with clients. I mostly have to resort to bringing down all directors, and restarting them all at once. Not really a workable solution. As an example, last night for a few hours we were getting complaints from customers about being disconnected, and the only obvious error in the log was the one above, after one of my colleagues had to restart a director because of some changes in the syslog daemon. After I restarted all directors withing a few seconds of each other, all complaints disappeared. Timo, i know ive asked similar questions before, but the answer just eludes me. If I have 3 director servers, and need to take one down and restart it, what is the proper method to reconnect the ring? In practice, I cant seem to work it out and I mostly end up with the above error until I just restart them all. Not fun with 20.000 clients connected. Cor

[Dovecot] Thunderbird 3.1 unable to delete subfolder of Trash under mdbox
by William Blunn 08 Apr '11

08 Apr '11

Thunderbird 3.1.9 over Windows 7. Dovecot 2.0.11 (2:2.0.11-0~auto+41 from http://xi.rename-it.nl/debian/ source on 8 Apr 2011) over Ubuntu 10.04 LTS. Trying to set up a Dovecot system with mdbox. But I also wanted to keep some Maildir. So I ended up with both mdbox and Maildir side-by-side and noticed an issue. On this system, Dovecot's global mail location is configured with maildir:~/Maildir I have a two users configured in a password-file passdb/userdb: One using the Dovecot global mail location (maildir:~/Maildir) the other with an override mail location (userdb_mail) of mdbox:~/mdbox (The only other configurations different to the default were to turn off the default system password passdb and userdb, and enable my local password-file-format passdb and userdb.) I have configured two IMAP accounts in Thunderbird 3.1.9, one to access each of the two users above. The test procedure is: In Thunderbird, create a folder at the top level (i.e. alongside Inbox), say "foo". In Thunderbird, delete the folder just created. This results in Thunderbird "moving" the folder to "Trash", resulting in a folder "Trash/foo". Up to this point, both the Maildir and mdbox users behave OK. Then in Thunderbird, delete the trashed folder "Trash/foo". At this point, things start to happen differently. With the Maildir user, the folder "Trash/foo" deletes successfully. But with the mdbox user, Thunderbird pops up an error: The current command did not succeed. The mail server for account <accountname> responded: Invalid mailbox name: Trash/foo/. The folder does disappear from the Thunderbird folder pane, but if Thunderbird is "prodded" to refresh what folders it thinks are there, then the folder reappears. If we check the user's mdbox directory, we can see that indeed the mailbox has not been deleted. Whatever I then do, I am unable to delete this folder in the mdbox user through Thunderbird. The only way I have found to safely delete the folder is to use "doveadm mailbox delete", but this requires root privilege on the server, which is not really a practical solution. It maybe a Thunderbird problem, but the question then arises: Why does it work under Maildir but doesn't work under mdbox? Any ideas? Bill

[Dovecot] fstat no such file or directory error
by Mark Dieterich 08 Apr '11

08 Apr '11

Periodically, we will have users IMAP sessions get hung. Their client sees a message like: The server responded: 'SERVERBUG] Internal error occurred. Refer to server log for more information On the server, we see the following in the logs: IMAP(<username>): Transaction log dovecot.index.log: duplicate transaction log sequence (37) IMAP(<username>): fscking index file dovecot.index IMAP(<username>): fstat() failed with index file dovecot.index: No such file or directory After the fstat message shows up, there doesn't appear to be anything on the user side that can be done to fix the problem. We've seen multiple instances where the file dovecot is complaining about not existing is visible, readable, and writable by the user in question, but dovecot is convinced it's not. The only way we've found to fix this issue is to kill off all user connections. When the user reconnects, then all appears to work fine. We have not found a way to recreate this problem. Some details: # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.8 Mail files are stored on NFS. All imap connections for a given user are are mapped to a particular server at any given time.

[Dovecot] shared folder: messages become invisible
by Burckhard Schmidt 08 Apr '11

08 Apr '11

Hello, after dealing with shared folder within version 2.0 rc* I started using it with a group of users. user1 shares a folder to user2. user2 has access to messages of this shared folder. After a "random" time (minutes up to several days) user2 doesn't see those messages anymore. user1 (the owner) hasn't changed anything inside this folder. All messages are still in place and normal visible for him. If user1 copies (whit TB) a messages into that folder user2 can see sometimes all messages again. But after a "random" time it happens again. user2 sees an empty shared folder. Deleting dovecot.index.log and dovecot.index.cache does not help. I have version 2.0.11 (2.0.10 same problem). mail_gid = sysdov mail_uid = sysdov namespace { inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace { list = yes location = maildir:%%h/maildir:CONTROL=~/control/FremdeOrdner/%%u:LAYOUT=fs prefix = FremdeOrdner/%%u/ separator = / subscriptions = no type = shared } mail_location = maildir:~/maildir:INDEX=/addons/index/%u:CONTROL=~/control:LAYOUT=fs I checked in a dialog: user1: 1 login user1 ... 1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in 1 list "" "*" ... * LIST (\HasChildren) "/" "94ssl" #this one is shared to user2 * LIST (\HasNoChildren) "/" "94ssl/ansicht" #this one too user2: 1 login user2 ... 1 OK [CAPABILITY ... 1 list "" "*" ... * LIST (\HasChildren) "/" "FremdeOrdner/user1/94ssl" * LIST (\HasNoChildren) "/" "FremdeOrdner/user1/94ssl/ansicht" ... user1: 1 examine 94ssl * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 2 EXISTS # 2 messages * 0 RECENT * OK [UIDVALIDITY 1301570235] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 4] Highest 1 OK [READ-ONLY] Select completed. 1 examine 94ssl/ansicht * OK [CLOSED] Previous mailbox closed. * FLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-0) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 6 EXISTS # 6 messages * 0 RECENT * OK [UIDVALIDITY 1301570236] UIDs valid * OK [UIDNEXT 7] Predicted next UID * OK [HIGHESTMODSEQ 14] Highest 1 OK [READ-ONLY] Select completed. user2 1 examine FremdeOrdner/user1/94ssl * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 0 EXISTS # no message, should be 2 * 0 RECENT * OK [UIDVALIDITY 1301570944] UIDs valid * OK [UIDNEXT 6] Predicted next UID * OK [HIGHESTMODSEQ 11] Highest 1 OK [READ-ONLY] Select completed. 1 examine FremdeOrdner/user1/94ssl/ansicht * OK [CLOSED] Previous mailbox closed. * FLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk unknown-0) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 0 EXISTS # no message, shold be 6 * 0 RECENT * OK [UIDVALIDITY 1301570943] UIDs valid * OK [UIDNEXT 33] Predicted next UID * OK [HIGHESTMODSEQ 37] Highest 1 OK [READ-ONLY] Select completed. user1/control/94ssl/dovecot-uidlist: 3 V1301570235 N1 G8406fb358864944d710300000cd09d4f 1 :1301570819.M719509P910.suncom2,S=1319,W=1348 2 :1301585261.M338176P881.suncom2,S=23758,W=24220 user1/control/94ssl/ansicht/dovecot-uidlist: 3 V1301570236 N1 G3e8f0f00b862944d6f0300000cd09d4f 1 :1301570366.M22178P901.suncom2,S=1149,W=1173 2 :1301575917.M12924P1028.suncom2,S=1035,W=1055 3 :1301576897.M502460P1043.suncom2,S=1156,W=1183 4 :1301580697.M399644P1089.suncom2,S=1147,W=1174 5 :1285149220.M287482P15434.suncom2,S=1122,W=1149 6 :1301582382.M287792P1196.suncom2,S=1019,W=1039 user2/control/FremdeOrdner/user1/dovecot-uidvalidity: 4d946580 user2/control/FremdeOrdner/user1/dovecot-uidvalidity.4d946580 user2/control/FremdeOrdner/user1/94ssl/dovecot-uidlist: 3 V1301570944 N6 G9536eb178474944db10300000cd09d4f 3 :1301585261.M338176P881.suncom2,S=23758,W=24220 4 :1301570819.M719509P910.suncom2,S=1319,W=1348 user2/control/FremdeOrdner/user1/94ssl/ansicht/dovecot-uidlist: 3 V1301570943 N33 G5efdb6247f65944d880300000cd09d4f 21 :1301570366.M22178P901.suncom2,S=1149,W=1173 22 :1301575917.M12924P1028.suncom2,S=1035,W=1055 23 :1301576897.M502460P1043.suncom2,S=1156,W=1183 24 :1301580697.M399644P1089.suncom2,S=1147,W=1174 25 :1301582382.M287792P1196.suncom2,S=1019,W=1039 26 :1285149220.M287482P15434.suncom2,S=1122,W=1149 -- regards --- Burckhard Schmidt

[Dovecot] doveadm search doesn't update fts
by metro_domain_admin＠fastmail.fm 08 Apr '11

08 Apr '11

Hello, Doveadm search is failing to update our Squat indexes. The search itself works fine but the dovecot.index.search* files remain unchanged. I tried: doveadm search -u test mailbox INBOX body sometext doveadm search -u test mailbox INBOX text sometext I also tried the exact syntax Timo expressed in an earlier post: doveadm search -A body asdf If I run the same search through IMAP, the index files update as expected. The searches finish with a clean exit status and nothing shows up in the logs. I upgraded from 2.0.0 to 2.0.11 but the problem remains. >From doveconf -n: plugin { fts = squat } protocol imap { mail_max_userip_connections = 16 mail_plugins = $mail_plugins fts fts_squat } Thank you, Tony

I am trying > not to chmod 777 every mailbox. I was going to write about the same problem. This got me over the hump: chmod 0600 /var/spool/mail/* All my user's mailboxes used to be group=mail mode=0660. I think these settings were left over from Solaris' mail.local: I can't reproduce these permissions now, even for new mailboxes. Maybe it's because the spool directory is now mode=1777 (not g+s mail). Not too keen on these permissions either, but it seems to work. Dovecot seems to transfer group permissions of the mailbox to its corresponding cache. If it can't set group ownership, you get the fatal error message above. If the original mailbox is mode 0600, dovecot is smart enough not to set group ownership. I couldn't find this information: shouldn't it be documented here? http://wiki2.dovecot.org/SharedMailboxes/Permissions This situation could also happen if a user is revoked from a group's membership. Would it be useful to make this a configurable behaviour whereby a chgrp() failure of cache files will fall back to chown'ing to user=owner, mode=0600 instead? Or just leave the user to scratch their head? Joseph Tam <tam(a)math.ubc.ca>

[Dovecot] LDA vs LMTP, Cyrus SASL, verbose_proctitle
by Joseph Tam 08 Apr '11

08 Apr '11

Is there a reason I should prefer LMTP over LDA for local delivery? Performance? Security? The Wiki doesn't differentiates LMTP vs LDA with respect to sendmail configuration, so am I correct that I just need to replace mail.local with dovecot-lda, which will choose LDA/LMTP based on dovecot.conf? Also, can I consolidate authentication by configuring dovecot to use what sendmail uses (Cyrus SASL) or vice versa? The Wiki hints this is in the works. Lastly, toggling verbose_proctitle seems to have no effect on the output of ps. Is verbose_proctitle broken for Solaris? Thanks, Joseph Tam <jtam.home(a)gmail.com>

Hi, I tried to use ATrpms (http://dl.atrpms.net/all/dovecot-2.0.11-1_126.src.rpm) to rebuild the rpms. It is shown the error message as following: configure: error: unrecognized option: --docdir=/usr/share/doc/dovecot-2.0.11 Try `./configure --help' for more information. I checked `./configure --help', it did contain the '--docdir' option. I don't know how to fix it. Then I tried to remove ' --docdir=%{_docdir}/%{name}-%{version} \' and rebuild it again. It is shown another error message as following: mv: cannot stat `/var/tmp/dovecot-2.0.11-1_126-root//usr/share/doc/dovecot-2.0.11': No such file or directory I tried to modify dovecot.spec again, replace 'mv $RPM_BUILD_ROOT/%{_docdir}/%{name}-%{version} %{_builddir}/%{name}-%{version}/docinstall ' with 'mv $RPM_BUILD_ROOT/%{_docdir}/%{name} %{_builddir}/%{name}-%{version}/docinstall' and rebuild it again. Antoher error shown 'File must begin with "/": %{_initddir}/dovecot', therefore I add '%define _initddir /etc/rc.d/init.d' Finally, I can rebuild the RPMS, but it is shown error message again while I install RPMS: [root@testmail SPECS]# rpm -ivh ../RPMS/x86_64/dovecot-2.0.11-1_126.x86_64.rpm Preparing... ########################################### [100%] 1:dovecot ########################################### [100%] /var/tmp/rpm-tmp.13056: line 3: syntax error near unexpected token `fi' /var/tmp/rpm-tmp.13056: line 3: `fi' error: %post(dovecot-2.0.11-1_126.x86_64) scriptlet failed, exit status 2 Please advise me how to fix the problem and thank you in advance. -- Best Regards, Bruce

[Dovecot] dovecot: auth(default): Can't open configuration file /etc/dovecot/dovecot-sql.conf: Permission denied
by Kevin P. McDonough 05 Apr '11

05 Apr '11

Hello, I have been searching all day for help on an issue I am having after installing and just having begun to configure dovecot. Whenever I try to start the dovecot daemon I receive the following errors in the syslog: Apr 4 13:15:03 ***** dovecot: auth(default): Can't open configuration file /etc/dovecot/dovecot-sql.conf: Permission denied Apr 4 13:15:03 *****dovecot: dovecot: Fatal: Auth process died too early - shutting down Now, I have gone through the config file (see below) trying various settings for auth including running it as root and as vmail. I have tried a number of permutations for the permissions and ownership on the file specified above from 600 root -> 777 vmail and everything in between, yet always the same issue. If I rename the file and try to start dovecot it notices that the file is missing and gives an appropriate error. I cannot figure out how the permissions can be wrong on the file, I am starting to assume it is a problem elsewhere. (One other note, I was initially getting an error regarding the rawlog permissions, and just removed the rawlog part of the IMAP config to work around that). ---cut--- *****:~ # l /etc/dovecot/ total 160 drwxr-xr-x 2 root root 4096 Apr 4 14:18 ./ drwxr-xr-x 98 root root 12288 Apr 4 17:41 ../ -rw-r--r-- 1 root root 52110 Apr 4 14:18 dovecot.conf -rw-r--r-- 1 root root 51576 Mar 16 13:31 dovecot.conf~ -rw-r--r-- 1 root root 410 Feb 22 19:03 dovecot-db-example.conf -rw-r--r-- 1 root root 782 Feb 22 19:03 dovecot-dict-sql-example.conf -rw-r--r-- 1 root root 4986 Feb 22 19:03 dovecot-ldap-example.conf -rw-r--r-- 1 root root 5589 Apr 4 13:25 dovecot-sql.backup -rw------- 1 root root 5589 Mar 16 13:31 dovecot-sql.conf -rw-r--r-- 1 root root 5097 Feb 22 19:03 dovecot-sql-example.conf ---cut--- ---cut--- *****:~ # dovecot -n # 1.2.16: /etc/dovecot/dovecot.conf Error: setmntent(/etc/mtab) failed: Permission denied # OS: Linux 2.6.37.1-1.2-desktop i686 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl: no disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login first_valid_uid: 5000 last_valid_uid: 5000 first_valid_gid: 5000 last_valid_gid: 5000 mail_location: maildir:/var/vmail/%d/%n/Maildir mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/rawlog /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 lda: postmaster_address: postmaster(a)example.com mail_plugins: sieve quota mail_plugin_dir: /usr/lib/dovecot/modules/lda auth_socket_path: /var/run/dovecot/auth-master auth default: mechanisms: plain login passdb: driver: pam passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir sieve: ~/.dovecot.sieve sieve_dir: ~/sieve ---cut--- I just noticed that setmntent error above, I havent seen that anywhere else previously.
