[Dovecot] Per-namespace proxying?
by VanL 03 Jan '09

03 Jan '09

Hello, Searching in the archives, I saw the following posting from Timo Sirainen: [Dovecot] Roadmap to future (06 Dec 2007): [...] > Proxying > -------- > > - These could be implemented to v1.2. - Log in normally (no proxying) > if destination IP is the server itself. > > - Support for per-namespace proxying: > > namespace public { > prefix = Public/ > location = proxy:public.example.org > } > > There are two choices for this: Dummy IMAP proxying or handling it with > a mail storage backend. Dummy IMAP proxying would just let the remote server > whose mailbox is currently selected handle most of the commands and their > replies. I'm just afraid that this will become problematic in future. > ... (continues) Was this feature ever implemented? Is it in the 1.2 alphas? On a related note, were virtual mailboxes implemented? Thanks, Van

[Dovecot] Unkillable imap process?
by Johan Persson 03 Jan '09

03 Jan '09

Hi, Not sure if this is relevant but having been running dovecot 1.1.4 for a long time (without any problem) I recently upgraded to 1.1.7 when I switched to SuSE 11.1 This is just running on my home server and it's a fairly standard fetchmail-procmail-dovecot setup. However I recently had an incident which I cannot quite explain. I suspect it could be a possible disk problem but I did run a SMART check and the disks and HW seems ok. The mail store is mounted on a separate partition using ext3 fs What happened was that I noticed that the load on my server went through the roof and that the imap process was hogging 100% of the CPU and it had been running so for over an hour. Before this happened I had just setup a new laptop with Thunderbird as the mail client and had just done a off-line sync of my whole mail store (~1.5GB). So for a short time the dovecot server would have been under maximum load. I tried to recover by gracefully shutting down dovecot and when that didn't stop the imap process I first tried to be nice by sending it the TERM signal and when that didn't do it, the KILL signal. However, I was not able to stop the imap process. I then decided to recycle the server and initiated a shutdown. However, not even that was able to complete (since the shutdown process seemed to be hanging on not being able to stop the imap process). In the end I was (for the first time in over 6 years) forced to use the hard reset button on the server. I do realize that this is almost impossible to diagnose, but does anyone now in general what could possible cause the imap process to so completely be locked up that it is impossible to even shut it down? The dovecot -n output is 1.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27.7-9-pae i686 openSUSE 11.1 (i586) ext3 log_path: /var/log/dovecot.err info_log_path: /var/log/dovecot.info login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 2 login_max_processes_count: 2 login_max_connections: 5 max_mail_processes: 32 mail_max_userip_connections: 8 mail_location: maildir:/srv/mail/%u mailbox_idle_check_interval: 15 fsync_disable: yes auth default: passdb: driver: pam userdb: driver: passwd Cheers Johan

[Dovecot] NFS, IDLE, and index locking
by Jack Stewart 31 Dec '08

31 Dec '08

Hi, I'll try to keep short. My primary question is what, in people's experience, are the best configuration settings for to avoid potential NFS cache locking issues in an interesting heterogeneous environment? We appear to have a workaround for some locking issues we have seen, which is turning off IDLE. Upgrading our version of dovecot from 1.1.4 is likely to address some core issues, but I want to get the system setup in tune first. There are some things in our setup that seem dumb, and I would like to make sure they are dumb. As far as our environment goes, it isn't unusual for our users to connect with multiple different clients from multiple locations. Some of these clients behave well, and some not so well. In addition we have multiple distributed servers with multiple instances. Generally the connection from one of their clients/desktops goes to the same server but their different desktops may connect to different servers. If anyone has a similar enough environment, do you find it better to have the hard link setting off or is it better for you to turn it on? The attribute cache is the default (60 seconds) which works well enough in a polling setting but may be a problem with IDLE (30 second check). Do you find it better to bump up the IDLE check interval or drop the attribute cache? Our cache and maildir are on separate NFS volumes so we can change one without changing the other. Our tcp timeout setting is too long (it is the default). Do you find 180-300 seconds more reasonable? ---Jack To give some context, we have a handful of users with intermittent caching locking where the dovecot.index.cache file would simply not update. One of our internal people managed to get this problem when he was using pine (non-IDLE) with gnubiff (IDLE) from the same desktop. We haven't had any alarms since taking the brute force approach of turning off IDLE. Unfortunately other projects are inhibiting my capacity for additional debugging at this time. Also, it isn't clear to me that we will learn anything useful since the servers do not appear to be tuned and they are only running dovecot 1.1.4. Just for reference, below is our dovecot configutation. disable_plaintext_auth = yes base_dir = /var/run/dovecot/imap-server-its/ protocols = imap imaps syslog_facility = local4 shutdown_clients = yes ssl_cert_file = xxx.pem ssl_key_file = yyy.key ssl_ca_file = zzz.pem mail_location = maildir:/var/spool/maildir/%1Ln/%Ln:INDEX=/var/spool/dovecot/indexes/%1Ln/%Ln login_greeting_capability = no verbose_proctitle = yes mail_debug = yes imap_capability = "IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1" # MAILDIR Performance settings maildir_copy_with_hardlinks = yes maildir_copy_preserve_filename = no # Handling web logins & imap traffic login_processes_count = 16 login_max_processes_count = 2048 max_mail_processes = 4096 mail_max_userip_connections = 2000 # NFS settings mmap_disable = yes fsync_disable = no mail_nfs_index = yes mail_nfs_storage = yes dotlock_use_excl = yes lock_method =fcntl protocol imap { listen = *:10143 ssl_listen = *:10993 imap_client_workarounds = delay-newmail outlook-idle netscape-eoh } ## Authentication processes namespace private { separator = . prefix = Mail. inbox = yes } auth_verbose = yes auth default { mechanisms = plain login passdb ldap { args = /etc/dovecot.conf-ldap } userdb static { args = uid=vmail gid=mail home=/var/spool/maildir/%1Ln/%Ln } socket listen { master { path = /var/run/dovecot/imap-server-its/auth-master user = vmail group = mail } user = root }

Would it work if you simply changed $apr1$ to $1$? I can't really see why $apr1$ would otherwise work in glibc. I just checked its sources and also Ubuntu patches.

[Dovecot] Bug in Dovecot 1.0.5 - CRYPT-MD5 not working
by Jim Salter 31 Dec '08

31 Dec '08

Problem: Using MySQL storage for the user and password db with MD5-CRYPT hashes, Dovecot fails to successfully authenticate when the MD5-CRYPT or MD5 settings are specified as default_pass_scheme in dovecot-mysql.conf. Dovecot /does/ successfully authenticate against MD5-CRYPT hashes when default_pass_scheme is set to CRYPT, which according to the docs should be DES encryption. (I do not know whether or not CRYPT actually works with DES hashes.) I am positive that I am using MD5-CRYPT hashes, as I have dropped in hashes from a Qmail/Vpopmail vpasswd file and they work with the CRYPT setting in Dovecot, as do hashes generated using htpasswd -nmb. Test system: Ubuntu Server 7.10, amd64 Dovecot 1.0.5 (from Ubuntu repositories) Postfix 2.4.5 (from Ubuntu repositories) Demonstration: # cat /etc/dovecot/dovecot-mysql.conf driver = mysql connect = dbname=redacted user=redacted host=127.0.0.1 password=redacted default_pass_scheme = MD5-CRYPT password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT maildir, 105 AS uid, 114 AS gid FROM mailbox WHERE username = '%u' # htpasswd -nmb user password user:$apr1$bZQl//..$2IPoOibTBaqpG7pPFigOy/ # mysql -u postfix -p mysql> use redacted; Database changed mysql> update userdb set password='$apr1$bZQl//..$2IPoOibTBaqpG7pPFigOy/' where username='user'; Query OK, 1 rows affected (0.00 sec) mysql>quit Bye # telnet localhost 143 Trying 127.0.0.1...

[Dovecot] Password field limitations
by Tom Sommer 29 Dec '08

29 Dec '08

Hi, I've searched the WIKI for this information but seem unable to find anything about it. What limitations are imposed on the password for IMAP/POP3 users? I've had a customer saying they can't use passwords which contain "." or ":", and some seem to have problems when the password is 8 characters. I use PLAIN authentication, passwords are stored in a MySQL database. Thanks a lot -- Tom Sommer

[Dovecot] automounting home dirs
by Roger Hale 29 Dec '08

29 Dec '08

Hi, I'm running dovecot-1.0.10 on a Solaris 10 server with home dirs automounted over NFS. I have set the mail_location configuration option so that nothing should be written to a user's home dir over NFS but, as far as I can tell, dovecot still by default tries to chdir to a user's home dir when reading mail, although this is not required. This creates additional unnecessary load on a heavily-loaded fileserver and generally slows everything down and creates an unnecessary dependency. Is there a way to prevent dovecot from causing the home dirs to be mounted? I found this thread: http://markmail.org/message/umywuppl3vvzfe4p#query:dovecot%20mount%20home%2… which discusses the same problem, but it's quite old and there doesn't seem to be a definitive answer other than hacking the passwd file or the code. Is there a more elegant solution? TIA. _________________________________________________________________ Get a bird’s eye view of the world with Multimap http://clk.atdmt.com/GBL/go/115454059/direct/01/

[Dovecot] Logging logs moved/deleted

26 Dec '08

Hi dovecot list, I'm looking for a possibility to log a moved (or a deleted mail). For example, I have a mailbox, and I read it in IMAP. I have a mail in INBOX. I want to move it to Folder. I want to have this action logged in my dovecot log file (or an other file). Is it possible? I read this: http://wiki.dovecot.org/Logging and I don't find any informations about it. I try to set "mail_debug=yes", but it does not log what I want. Thanks. Best regards (and happy Xmas). -- -Nicolas.

Would it be better, faster? Thanks

[Dovecot] Is there a straight forward way to associate login with imap process

23 Dec '08

Hi, Is there a way to associate a user's the login (imap-login) process with the user's 'imap [' process? We are trying to lock down an issue to make sure we full understand it. /proc and shared memory tools weren't particular useful. Just for context, we are having an intermittent locking index cache locking issue that appears to impact only a subset of our users. The index files are on NFS. It may be fixed by a dovecot patch (we are at 1.1.3), adjusting our tcp_timeout on the servers, upgrading out circa 2000 load balancer, the type and configuration of the multiple simultaneous persistent clients that user is using, etc. lslk, alert logs, strace, testing the most recent 1.1.X version, and file mtime is giving us some information but we want to make everything is covered. Many thanks in advance. ---Jack -- Jack Stewart California Institute of Technology jstewart(a)caltech.edu / www.imss.caltech.edu

[Dovecot] SSL certs per listen IP
by Ian P. Christian 21 Dec '08

21 Dec '08

I'd like to host multiple domains though a central dovecot proxy - however, I need to present different certs to different hostnames (which are on different IPs). I can't see a way to this in the documentation, is it possible? thanks, Ian

[Dovecot] Move mail in Maildir without IMAP
by RW 21 Dec '08

21 Dec '08

I set-up some spam/ham learning folders where a crontab entry learns the mail and them moves it do a different Maildir folder. Unfortunately, since it has a different dovecot-keywords file, any imap flags get changed to unknown-0, unknown-1 etc. I tried the following, but it didn't work mv "${src_ham}"/cur/* "$dest_ham"/new/ cp "${src_ham}"/dovecot-keywords "${dest_ham}" Is there a simple way to do this correctly without going through IMAP? And are there any more serious consequences of moving mail like this, with dovecot imap running on top.

[Dovecot] Dovecot with LDAP on multiple domains ?
by Guillaume Hilt 20 Dec '08

20 Dec '08

Hello, I intend to set up a mail server for a few domains with Dovecot/Postfix/MySQL/DSPAM and antispam plugin. The better solution to manage users would be to set up a ldap server. So, do anyone have ever set up this kind of server with dovecot ? Any advice that would help me ? Thanks, -- Guillaume Hilt

[Dovecot] Heartbeat OCF ressource agent

Hello, I've tried to write an OCF ressource agent in order to manage by the heartbeat way a dovecot server. It seems to work fine. This kind of script could be found in the directory on a CentOS release 5.2 : /usr/lib/ocf/resource.d/ If the attachement isn't working, I've cut and paste the script here : http://www-sop.inria.fr/members/Mathieu.Kretchner/dotclear/index.php/2008/1… #!/bin/bash -p # # $Id: ha-dovecot,v 1.2 2008/12/19 09:32:27 mkretchn Exp $ #---+ Notes ## Cf: http://linux-ha.org/OCFResourceAgent ## http://www.opencf.org/cgi-bin/viewcvs.cgi/specs/ra/resource-agent-api.txt?r… ## /usr/share/heartbeat/crm.dtd #---+ Contexte OCF # Pour execution (status monitor) hors controle de heartbeat if [ -z "$OCF_ROOT" ]; then OCF_ROOT=/usr/lib/ocf fi source ${OCF_ROOT}/resource.d/heartbeat/.ocf-shellfuncs #---+ Actions usage () { echo "Usage: $0 {start|stop|monitor|meta-data|validate-all}" } meta_data () { local rev="$Revision: 1.2 $" rev=${rev#* }; rev=${rev% *} cat <<EOF <?xml version="1.0"?> <!DOCTYPE resource-agent SYSTEM "ra-api-1.dtd"> <resource-agent name="ha-dovecot"> <version>$rev</version> <longdesc lang="en"> dovecot </longdesc> <shortdesc lang="en">dovecot RA</shortdesc> <actions> <action name="start" timeout="1m"/> <action name="stop" timeout="1m"/> <action name="monitor" interval="30s" timeout="20s" start-delay="1m" /> <action name="validate-all" timeout="5s" /> <action name="meta-data" timeout="5s" /> </actions> </resource-agent> EOF } exec="/usr/sbin/dovecot" bin=$(basename $exec) config="/etc/dovecot.conf" start () { [ -x $exec ] || { echo >&2 "** $exec not executable" return $OCF_ERR_GENERIC } [ -f $config ] || { echo >&2 "** $config doesn't exist" return $OCF_ERR_GENERIC } local pid=$(dovecot_pid) if [ "$pid" ]; then echo >&2 "dovecot already running" return $OCF_SUCCESS elif $exec; then local pid=$(dovecot_pid) if [ "$pid" ]; then return $OCF_SUCCESS else echo >&2 "** no dovecot pid" return $OCF_ERR_GENERIC fi else echo >&2 "** $bin fails to start" return $OCF_ERR_GENERIC fi } stop () { local pid=$(dovecot_pid) echo $pid if [ "$pid" ]; then if killpid $pid; then return $OCF_SUCCESS else echo >&2 "** killpid $pid: fails" return $OCF_ERR_GENERIC fi else return $OCF_SUCCESS fi } status () { # Seems to not be used by heartbeat return } monitor () { local pid=$(dovecot_pid) if [ "$pid" ]; then MYSTATUS=`echo ". logout" | nc localhost 143 | grep "ready" | wc -l` if [ "$MYSTATUS" -eq "1" ]; then return $OCF_SUCCESS else return $OCF_ERR_GENERIC fi else return $OCF_NOT_RUNNING fi } validate_all () { return } #---+ Utilitaires dovecot_pid () { pidof $bin } # Check if $pid (could be plural) are running checkpid() { local i for i in $* ; do [ -d "/proc/$i" ] && return 0 done return 1 } killpid () { # Repris depuis /etc/init.d/functions:killproc # killpid <pid> [<delai en secondes>] # FIXME: faire faire ca par lps -k ou autre option? local pid=$1 local delay=${2:-3} # Succes si pas de process checkpid $pid || return 0 # TERM first, then KILL if not dead kill -TERM $pid usleep 100000 if checkpid $pid && sleep 1 && checkpid $pid && sleep $delay && checkpid $pid ; then kill -KILL $pid usleep 100000 fi if checkpid $pid; then return 1 else return 0 fi } #---+ Debug [[ $0 == *bash ]] && return #---+ Main if [ $# -eq 0 ] then usage exit $OCF_ERR_ARGS fi # PATH source /usr/local/bashutil/autoload_lib autoload_lib /usr/local/bashutil/lib/batch case $1 in start) start ;; stop) stop ;; status) status ;; monitor) monitor ;; meta-data) meta_data;; validate-all ) validate_all;; *) usage exit $OCF_ERR_UNIMPLEMENTED ;; esac
