[Dovecot] Dovecot-2.1.14 - pop3 processes always hangs forever - a follow-up
by Axel Luttgens 08 Feb '13

08 Feb '13

Suspecting a problem with the "virtual" uids/gids, I've tried with a real user for the mail user: # 2.1.14: /_ETC/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 auth_verbose = yes disable_plaintext_auth = no mail_debug = yes mail_gid = dovemailer mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox mail_uid = dovemailer passdb { args = /_ETC/dovecot/db.conf driver = sql } ssl = no userdb { driver = prefetch } Of course, the db queries do not return uid/gid pairs anymore. And the pop3 processes now seem to work as expected; connecting for the first time as user1: $ telnet 127.0.0.1 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user user1 +OK pass pass1 +OK Logged in. list +OK 0 messages: . quit +OK Logging out. Connection closed by foreign host. Hmmm... Axel

[Dovecot] Dovecot-2.1.14 - pop3 processes always hangs forever
by Axel Luttgens 08 Feb '13

08 Feb '13

Hello, I'm currently experimenting with the 2.1.x series and am facing a behavior I can't explain; I must be doing something wrong and probably miss the obvious... ;-) This is a very basic build on Mac OS X 10.8.2: ./configure --prefix=/_COD/dovecot-2.1.14 --sysconfdir=/_ETC --localstatedir=/_VAR --with-sqlite --with-ldap=yes (Yes, I know, a strange layout, yet very convenient for testing various things here.) Dovecot's configuration is very basic too: # 2.1.14: /_ETC/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 auth_verbose = yes disable_plaintext_auth = no mail_debug = yes mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox passdb { args = /_ETC/dovecot/db.conf driver = sql } ssl = no userdb { driver = prefetch } It is started from launchd with the -F flag. Two users are defined in the database, user1 (100002/100002) and user2 (100003/100003), with "virtual" uids/gids. Connecting for the first time as user1 through imap: $ telnet 127.0.0.1 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. a login user1 pass1 a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE] Logged in b logout * BYE Logging out b OK Logout completed.

But this is noticed by the master process: dovecot[2997]: pop3(user2): Fatal: master: service(pop3): child 3113 killed with signal 9 Note that it is possible to connect afterwards as user2 through imap. On the other hand, trying to connect as user1 or user2 through pop always hangs. TIA, Axel

[Dovecot] dsync: Invalid server handshake
by Dusan Zivadinovic 08 Feb '13

08 Feb '13

Hi list, I recently tried to backup mailboxes from an older server machine to a new one in order to move the service to the new machine. Both machines are in the same LAN, I used this command: dsync -R -u username backup ssh -i .ssh/id_rsa username(a)192.168.1.11 /opt/local/bin/dsync and I get this error: dsync-local(dz): Error: Invalid server handshake: dsync-server 2 dsync-remote(dz): Error: Invalid client handshake: dsync-client 1 # lokal machine: dovecot 2.0.19apple1 running on Mac OS X 10.8.2 Server using standard Apple-Dovecot-Configuration # remote machine: 2.1.12 running on Mac OS X 10.4 using PAM authentication I cant seem to find any documentation to this error, nor do I find any dsync entries in the logs of both machines. Does anyone have a hint? Thank you, Dusan

[Dovecot] File permissions used for automatically created mailbox
by Frerich Raabe 07 Feb '13

07 Feb '13

Hi, I'm running Dovecot 2.1.12 on FreeBSD (quite successfully so, thanks for this nice piece of software!). One thing which is slightly annoying though is that automatically created mailboxes (I have lda_mailbox_autocreate set) don't have the file permissions I'd like them to have. I'm using a vmail-based system, i.e. all mail is owned by vmail:vmail; another member of the vmail group is called 'backup', which has read access to all mail in order to create backups. All mail is stored beneath /home/vmail, e.g. /home/vmail/frerich/Maildir Right now, newly created mailbox directories (e.g. /home/vmail/bob) have 0700 permissions, but I'd like to have 0750 for all directories and 0640 for all files so that all files and directories are group-readable for backup purposes. Does anybody know whether this is configurable somehow? Right now, my workaround consists running this cron script every night: #!/bin/sh chown -R vmail:vmail /home/vmail/ find /home/vmail/ -type d -print0 | xargs -0 chmod 0750 find /home/vmail/ -type f -print0 | xargs -0 chmod 0640 -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

[Dovecot] Subfolders problem
by Adam Maciejewski 06 Feb '13

06 Feb '13

I have moved from dovecot 1.x to 2.x and I have big problem with subfolders. When I'm moving subfolder with other subfolders is moving only main subfolder, without subfolders, example : mail-storage-1 /var/vmail/home/adamskitest/mdbox/mailboxes # find | egrep -e "janusz|jarek" ./jarek ./jarek/dbox-Mails ./jarek/dbox-Mails/dovecot.index.log ./jarek/jarek2 ./jarek/jarek2/dbox-Mails ./jarek/jarek2/dbox-Mails/dovecot.index.log ./jarek/jarek2/jarek3 ./jarek/jarek2/jarek3/dbox-Mails ./jarek/jarek2/jarek3/dbox-Mails/dovecot.index.log ./janusz ./janusz/dbox-Mails ./janusz/dbox-Mails/dovecot.index.log ./janusz/janusz2 ./janusz/janusz2/dbox-Mails ./janusz/janusz2/dbox-Mails/dovecot.index.log ./janusz/janusz2/janusz3 ./janusz/janusz2/janusz3/dbox-Mails ./janusz/janusz2/janusz3/dbox-Mails/dovecot.index.log And now I'm moving jarek2 with jarek3 as subfolder to janusz2 subfolder, result : mail-storage-1 /var/vmail/home/adamskitest/mdbox/mailboxes # find | egrep -e "janusz|jarek" ./jarek ./jarek/dbox-Mails ./jarek/dbox-Mails/dovecot.index.log ./jarek/jarek2 ./jarek/jarek2/jarek3 ./jarek/jarek2/jarek3/dbox-Mails ./jarek/jarek2/jarek3/dbox-Mails/dovecot.index.log ./janusz ./janusz/dbox-Mails ./janusz/dbox-Mails/dovecot.index.log ./janusz/janusz2 ./janusz/janusz2/dbox-Mails ./janusz/janusz2/dbox-Mails/dovecot.index.log ./janusz/janusz2/dbox-Mails/dovecot.index.cache ./janusz/janusz2/janusz3 ./janusz/janusz2/janusz3/dbox-Mails ./janusz/janusz2/janusz3/dbox-Mails/dovecot.index.log ./janusz/janusz2/jarek2 ./janusz/janusz2/jarek2/dbox-Mails ./janusz/janusz2/jarek2/dbox-Mails/dovecot.index.log As You can see there is jarek2 subfolder but jarek3 havent been moved.

Hi all, let me ask a question, please. Is it possible in dovecot to set up per user special-use folder names? Imagine situation with two users where first prefere another language that second. mailbox Sent { special_use = \Sent } for english speaking users and mailbox "Odeslaná pošta" { special_use = \Sent } for czech speaking users.

[Dovecot] Sieve not filtering
by Nicolas Mora 06 Feb '13

06 Feb '13

Hello, I installed a few weeks ago the Dovecot package on a Debian stable along with postfix, everything works fine except the sieve filter. I followed the howto found on the internet (google: debian postfix dovecot sieve). I'm able to view and modify sieve rules with roundcube or thunderbird plugins, but the rules are not applied when a message arrives and all messages arrive in INBOX. Here is the content of my configuration files concerning sieve : dovecot.conf protocols = imap imaps managesieve protocol managesieve { listen = *:2000 } protocol managesieve { mail_executable = /usr/lib/dovecot/managesieve managesieve_max_line_length = 65536 managesieve_logout_format = bytes=%i/%o } protocol lda { postmaster_address = postmaster(a)babelouest.org mail_plugins = sieve mail_plugin_dir = /usr/lib/dovecot/modules/lda log_path = info_log_path = syslog_facility = mail } plugin { sieve_dir=~/Maildir/sieve } And the postfix/main.cf config file contains for dovecot sieve the following maibox_command = /usr/lib/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT" dovecot_destination_recipient_limit = 1 virtual_transport = dovecot I also tried the command mailbox_command = /usr/lib/dovecot/deliver it didn't work either... Is there somthing so obvious that I didn't see it ? Thanks in advance

[Dovecot] move mail from server with v1.0 to server w. v2.1?
by Frank Lienhard 06 Feb '13

06 Feb '13

I'm about to replace my old server. Both servers are on my internal network. The old one ist running debian lenny(32bit) with dovecot 1.0.15 and the new one debian Wheezy with dovecot 2.1.7. I set up the users on both systems identically (same gid uid). My first attempt was tho simply rsync the Maildirs along with the homes. Both deovecot versions are set up with the maildir format, but this results in ~30% doublicated mails on the new server. I then learned about doveadm/dsync, only to figure out that this isn't available in v 1.0.15 and therefor won't work. So which could be the most painless way to solve that?

[Dovecot] dsync backup questions
by Joe Beaubien 06 Feb '13

06 Feb '13

Hi, I'm currently trying to setup remote backups of my emails but i'm running into issues (mdbox format, indexes and storage in the same folder hierarchy). Local backup command: dsync -u "my_user" backup /backups/my_user (1) Recently, I noticed that the local backup takes up twice the size as the original mail location (8gb vs. 4gb). I purged alot of emails from the original location, so the size shrunk, but the local backup just keeps on getting bigger. I couldn't find any dsync option that would delete extra emails. - Question: Why isn't the local backup synced properly and remove the extra emails? (2) What is the best why to copy this local backup to a remote location that does NOT have the possibility to run dsync. - Question 1: is rsync safe to use and will this data work for restore? - Question 2: Would it be safe to simply rsync the original mail_location to the remote server? I searched the net, but it seems that mdbox is tricky to backup. Thanks in advance, -Joe

05 Feb '13

Version 2.1.10 For some reason Mutt doesn't list any info about IMAP folders and seems to ignore folder_format. My questions is does anyone have any workarounds for this?

[Dovecot] Upgrade from 2.1.13 to 2.1.14 and load doubled
by Alessio Cecchi 05 Feb '13

05 Feb '13

Hi, during the weekend I upgrade my mail servers from dovecot 2.1.13 to dovecot 2.1.14 (and rebuild dovecot-2.1-pigeonhole-0.3.3). After upgrade all works fine, but today the load avarage un MXs is doubled. Mailboxes are in Maildir/ on NFS and I'm using dovecot as LDA and dict quota only for quota usage. May be a problem with the new version? This is my configuration: $ ./configure --prefix=/usr/local/dovecot-2.1 --with-vpopmail --with-mysql --with-bzlib --with-zlib # cat /usr/local/dovecot-2.1/etc/dovecot/sieve/default.sieve require ["vnd.dovecot.duplicate", "fileinto", "mailbox"]; if header :contains "X-Spam-Status" "Yes" { fileinto "Spam"; } if header :contains "Subject" "TEST 123" { fileinto "Spam"; } if duplicate { fileinto "Trash"; } ##################### # 2.1.14: /usr/local/dovecot-2.1/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.6 auth_cache_size = 512 k auth_worker_max_count = 60 default_login_user = nobody dict { acl = mysql:/usr/local/dovecot-2.1/etc/dovecot/dovecot-share-folder.conf expire = mysql:/usr/local/dovecot-2.1/etc/dovecot/dovecot-dict-sql.conf.ext quota = mysql:/usr/local/dovecot-2.1/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no dotlock_use_excl = no first_valid_gid = 89 first_valid_uid = 89 last_valid_gid = 89 last_valid_uid = 89 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes log_path = /var/log/dovecot/dovecot.log mail_fsync = always mail_location = maildir:~/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = quota acl zlib expire maildir_very_dirty_syncs = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave vnd.dovecot.duplicate mmap_disable = yes namespace { list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = shared/%%n/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / } passdb { args = cache_key=%s%u webmail=192.168.113.215 driver = vpopmail } plugin { acl = vfile:/usr/local/dovecot-2.1/etc/dovecot/global-acls:cache_secs=300 acl_shared_dict = proxy::acl expire = Trash expire2 = Spam expire_dict = proxy::expire quota = maildir:UserQuota quota2 = dict:User quota::noenforcing:proxy::quota quota_rule2 = Trash:storage=+100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u sieve = ~/.dovecot.sieve sieve_default = /usr/local/dovecot-2.1/etc/dovecot/sieve/default.sieve sieve_dir = ~/sieve sieve_extensions = +vnd.dovecot.duplicate } protocols = imap pop3 sieve service auth { unix_listener auth-userdb { group = vchkpw mode = 0660 user = vpopmail } } service dict { unix_listener dict { group = vchkpw mode = 0660 user = vpopmail } } service imap-login { service_count = 0 } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { service_count = 0 } service quota-warning { executable = script /usr/local/dovecot-2.1/etc/dovecot/scripts/quota-warning.sh unix_listener quota-warning { user = vpopmail } user = vpopmail } ssl_cert = </etc/ssl/certs/wildcard.pem ssl_key = </etc/ssl/private/wildcard.key submission_host = localhost userdb { args = quota_template=quota_rule=*:backend=%q driver = vpopmail } protocol lda { log_path = /var/log/dovecot/lda.log mail_plugins = quota acl zlib expire sieve } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep tb-lsub-flags imap_idle_notify_interval = 29 mins mail_max_userip_connections = 18 mail_plugins = quota acl zlib expire imap_quota imap_acl } protocol sieve { mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 5 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } Thanks -- Alessio Cecchi is: @ ILS -> http://www.linux.it/~alessice/ on LinkedIn -> http://www.linkedin.com/in/alessice Assistenza Sistemi GNU/Linux -> http://www.cecchi.biz/ @ PLUG -> ex-Presidente, adesso senatore a vita, http://www.prato.linux.it

[Dovecot] lmtp-proxying in 2.1 slower than in 2.0.14 ?
by Jan-Frode Myklebust 05 Feb '13

05 Feb '13

We upgraded our two dovecot directors from v2.0.14 to dovecot-ee 2.1.10.3 this week, and after that mail seems to be flowing a lot slower than before. The backend mailstores are untouched, on v2.0.14 still. After the upgrade we've been hitting process_limit for lmtp a lot, and we're struggeling with large queues in the incoming mailservers that are using LMTP virtual transport towards our two directors. I seem to remember 2.1 should have a new lmtp-proxying code. Is there anything in this that maybe needs to be tuned that's different from v2.0 ? I'm a bit scheptical to just increasing the process_limit for LMTP proxying, as I doubt running many hundreds of simultaneous deliveries should work that much better against the backend storage.. ###### doveconf -n ########## # 2.1.10.3: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.32.1.el5 x86_64 Red Hat Enterprise Linux Server release 5.5 (Tikanga) default_client_limit = 4000 director_mail_servers = 192.168.42.7 192.168.42.8 192.168.42.9 192.168.42.10 192.168.42.28 192.168.42.29 director_servers = 192.168.42.15 192.168.42.17 disable_plaintext_auth = no listen = * lmtp_proxy = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave passdb { args = proxy=y nopassword=y driver = static } protocols = imap pop3 lmtp sieve service anvil { client_limit = 6247 } service auth { client_limit = 8292 unix_listener auth-userdb { user = dovecot } } service director { fifo_listener login/proxy-notify { mode = 0666 } inet_listener { port = 5515 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service imap-login { executable = imap-login director process_limit = 4096 process_min_avail = 4 service_count = 0 vsz_limit = 256 M } service lmtp { inet_listener lmtp { address = * port = 24 } process_limit = 100 } service managesieve-login { executable = managesieve-login director inet_listener sieve { address = * port = 4190 } process_limit = 50 } service pop3-login { executable = pop3-login director process_limit = 2048 process_min_avail = 4 service_count = 0 vsz_limit = 256 M } ssl_cert = </etc/pki/tls/certs/pop.example.com.cert.ca-bundle ssl_key = </etc/pki/tls/private/pop.example.com.key protocol lmtp { auth_socket_path = director-userdb } ################ -jf

[Dovecot] dsync-local(user): Error: proxy client timed out
by Metro Domain Admin 05 Feb '13

05 Feb '13

Hello, I have an intermittent but frequent problem using dsync backup. The command outputs: dsync-local(user): Error: proxy client timed out Then dies with exit code 75. Any subsequent attempts to re-run the backup invariably fail like this: dsync-local(user): Warning: Destination mailbox INBOX has been modified, need to recreate it before we can continue syncing dsync-local(user): Error: read() from worker server failed: EOF dsync-local(user): Error: msg-copy returned invalid input: dsync-local(user): Error: remote: dsync-remote(user(a)domain.com): Error: Can't delete mailbox INBOX: INBOX can't be deleted. dsync-remote(l_user(a)domain.com): Error: command MSG-SAVE failed dsync-local(user): Warning: Mailbox changes caused a desync. You may want to run dsync again. The syntax I am using is: dsync -u $user backup \ ssh -i <idfile> <user@host> \ dsync -u l_$user We have this running in a script that loops through all users. The error happens mostly on the larger mailboxes but I've seen it succeed on the largest ones then fail on smaller. One mid-sized account now fails consistently. The backup is running from a Mac OS PPC server running 2.1.12 The target is a Linux Intel box running 2.1.13, but I had the same problem sending to a Mac OS Intel on 2.1.12. Mdbox in all cases. Thanks, Tony

[Dovecot] Overloading IMAP Server
by Harford, Ken 04 Feb '13

04 Feb '13

Hi All, I am having an issue with dovecot IMAP reading and writing to one specific mailbox. I have a check email delivery script that sends out a email and then logs into dovecot to check if the mailbox that the message has been delivered to. However, the servers that send these messages send them in bunches depending on how many postfix spools it is checking. So I could get 60 messages all being sent to 1 mailbox and then having to read that same mailbox to check if the message actually got delivered. I am using postfix as the MTA and dovecot is actually delivering the message to the mailbox I am getting a lot of errors such as the following: Could not connect to IMAP server imap failed: IMAP RECEIVE CRITICAL - Could not select INBOX Any ideas as to what I can tweak in dovecot to allow these messages to be verified. Thanks for any information or help you could provide!! Ken

[Dovecot] Reviewing end-user ham/spam submissions before feeding them to sa-learn via Dovecot Antispam plug-in
by Ben Johnson 01 Feb '13

01 Feb '13

Currently, I'm using the Dovecot Antispam plug-in with great success. Everything works as expected. However, I would like to change the plug-in's behavior such that it simply sends a copy of a message that is moved from Inbox -> Junk (or Junk -> Inbox) to an administrator, instead of calling sa-learn (I'm using SpamAssassin) automatically. Basically, I would like to be able to review messages that end-users submit for training before they are actually fed to sa-learn. Has anyone had a similar need? If the Antispam plug-in already supports this, if the necessary commands can simply be added to the shell script that Antispam calls, or if there is a better method altogether, any help is greatly appreciated. Thank you! -Ben

[Dovecot] Dovecot Director Doveadm fails when there are a lot of output information
by Ramon Frontera 31 Jan '13

31 Jan '13

Hi, we are running dovecot 2.1.13 We have 2 proxies with director and 4 mail servers. we use LDAP when we execute doveadm-quota -A and doveadm with few output lines, its works fine. When we use doveadm-search or doveadm-mailbox with a lot of output information the command stops the execution and the command no ends. The connection to one of the 4 mailserver has finished at this moment. I have made some tests and i have found that if we use only one mailserver the commands works fine. I put the gdm bt output hope it help you.

[Dovecot] sieve_max_redirects=0 not working as documented
by Arnaud Abélard 31 Jan '13

31 Jan '13

Hello I'm trying to keep my users from using the "redirect" action with pigeonhole from dovecot 2.0.21. As documented in http://wiki2.dovecot.org/Pigeonhole/Sieve/Configuration I configured sieve like this: plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_max_redirects = 0 } (and doveconf indeed shows the new setting for sieve_max_redirects) Unfortunately I can still use the redirect action: lda(dummy(a)univ-nantes.fr): Debug: sieve: executing script from /vmail/d/u/dummy/.dovecot.svbin lda(dummy(a)univ-nantes.fr): sieve: msgid=<510A758D.1030305(a)univ-nantes.fr>: forwarded to <xxxx(a)xxxxx.com> what could I have missed?

[Dovecot] v2.1.14 released
by Timo Sirainen 30 Jan '13

30 Jan '13

http://dovecot.org/releases/2.1/dovecot-2.1.14.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.14.tar.gz.sig If you've been waiting for a fully stable release after the recent cache file troubles in v2.1.11+, this release should be the one. Hopefully there won't be v2.1.15 anytime in near future. (v2.2.rc1 does look close though.) BTW. I know there are quite a lot of mails I haven't replied to in dovecot list. Too busy for now.. + doveadm acl recalc command added - v2.1.11+ had a race condition where it sometimes overwrote data in dovecot.index.cache file. This could have caused Dovecot to return the same cached data to two different messages. - mdbox: Fixes to handling duplicate GUIDs during index rebuild

[Dovecot] decode2text.sh
by bhs692-dove＠yahoo.com 30 Jan '13

30 Jan '13

Dovecot version: 2.1.13 OS: Centos 6.3 CPU: 64bit x86 There appear to be two related errors in the decode2text.sh file (which can be used for indexing/ searching attachments). - The layout of "$formats" has repeated values for pdf, ppt, etc, so you should only match the pattern once by adding -m1 - The layout of "$formats" has the file extension in the second "column", so the "start of line"(^) match doesn't work as is. Original problem line (from ./src/plugins/fts/decode2texh.sh): fmt=`echo "$formats" | grep -w "^$content_type" | cut -d ' ' -f 2` Here are two options that appear to solve the problem. The first option is probably preferred, since it matches exactly the extension to the second "column". 1) switch the order of commands (cut & grep) and add -m1. for example: fmt=`echo "$formats" | cut -d ' ' -f 2 | grep -w -m1 "^$content_type"` -OR- 2) add "m1" and remove "^". for example: fmt=`echo "$formats" | grep -w -m1 "$content_type" | cut -d ' ' -f 2`

[Dovecot] passdb to add extra fields?
by Timo Sirainen 30 Jan '13

30 Jan '13

Some passdbs like PAM can't really return any extra fields. Also some people have wanted to combine users' data from different passdb/userdbs so that for example you'd have userdb passwd give the uid/gid/home, but then you'd also have some other userdb give quota limits. So I was thinking something like this: passdb { driver = pam } passdb { driver = sql include = yes } or: userdb { driver = passwd } userdb { driver = passwd-file include = yes } I'm not sure about two things: 1) Should there be a way to replace all of the existing fields instead of just adding new ones? 2) Any thoughts of a better name than "include"? With passdb it would mean that it's included only when the authentication failed for some other passdb. With userdb it means it's included only if a previous userdb lookup succeeded. Also there are already "deny" and "pass" settings. Interaction with them can be somewhat confusing.. Maybe all of these should be replaced with: type=deny: Same as old deny=yes (deny auth if user is in list) type=precondition(?): Same as pass=yes (require another passdb to match) type=postcondition(?): Require user to exist in this passdb/userdb as well, adding any extra fields in it. type=add: Add any extra fields, if the user exists at all. (Better ideas for the names here? Is even "type" a good name?) Then maybe a new setting to delete existing extra fields .. or perhaps just extend passdb { override_fields } so that having "-field" would delete the field if it already existed..

[Dovecot] A lot of dovecot/imap processes
by Juan Cifo Servera 30 Jan '13

30 Jan '13

Hello! I have a dovecot installed and many users could login via IMAP over SSL (40 users at same time aprox). Users could have "Check mail every X time" enabled in their client (Thunderbird or K-9 mail) - Is this required feature? I noted that if I disable it I still getting news mails without having to check for new mails manually - . I noted that dovecot is creating a lot of process (dovecot/imap and dovecot/imap-login) and is requiring more and more RAM. I think that every login starts a process but never is endend. The output of /*ps aux | grep dovecot | wc*/ is increasing until 250 lines aprox. I think that is limited by process_limit = 256. But if I put process_limit = 100, in the log appers a message that dovecot is aborting logins (and I noted that new connections sometimes couldn't login). Anyway the mailserver is working well, but I'm afraid of the consumtion of RAM. Is that normal?

Is there any documentation anywhere on creating a new storage plugin besides looking through the existing storage code? It's a pretty extensive task and any documentation would help. Thanks

[Dovecot] help with public namespace/mailbox
by michael＠los-pollos.co 30 Jan '13

30 Jan '13

Dear all, I am hoping someone can help me with a problem that I have been trying to fix for days. Using postfix and dovecot 2.0.19 on Ubuntu 12.04 with LDAP authentication and virtual users and domains. Basically I want to setup both shared and public mailboxes. The shared part is working fine, ie I can share folders successfully and other uses can see them. However when I try and create sub folders in the public folder they don't show up in the client. I have tried creating them in manually in the filesystem ie mkdir .folder and also via thunderbird. I have read through the dovecot wiki's several times over and still cannot see why it won't work. I have debug turned on and these are the log messages I get in syslog when I start up thunderbird: acl: No lookup right to mailbox: public/folder acl vfile: file /home/example.com/public/.folder/dovecot-acl not found acl vfile: file /home/example.com/public/dovecot-acl not found So I create the dovecot-acl file manually in public and set the right file system permissions and the errors go away, yet the folder still doesn't get created despite the following getting logged in syslog. Jan 29 23:43:57 alpha dovecot: imap(testuser(a)example.com): Debug: Namespace public/: /home/example.com/public/.folder2 doesn't exist yet, using default permissions Jan 29 23:43:57 alpha dovecot: imap(testuser(a)example.com): Debug: Namespace public/: Using permissions from /home/example.com/public: mode=0777 gid=-1 Right now I am thinking the problem might be that I am trying to setup both shared and public namespaces within the same configuration and therefore dovecot is looking for acl's for the public when it shouldn't be? Feel like I am stabbing in the dark with this though. Any help anyone can offer will be greatly appreciated! Thanks in advance. Regards, Michael.

[Dovecot] Duplicate supression mechanism

Hello, In a Dovecot 2.0.6 server I have an account x@domain and an alias y@domain -> x@domain. When I send an email to x@domain with carbon copy to y@domain, X receives two messages on mailbox. Dovecot2 has any feature of duplicate suppression ? Thanks -- Thiago Henrique adminlinux.com.br

[Dovecot] dovecot.index is missing
by Alexandr Sabitov 30 Jan '13

30 Jan '13

Dear All, I have noticed that dovecot.index is not generated straight away if you have just a few emails in the mailbox. Instead of that dovecot.index.log is modified and accessed by clients. Only if the number of email reaches some level then it creates dovecot.index in user mailboxes. Can somebody please tell me when (in my understanding of the process) the index log file drops all data into the mail index file. What does trigger that ? Sorry I couldn't find any info on that in the wiki. Best Regards, Alexandr Sabitov

[Dovecot] password schemes in dovecot
by Public 28 Jan '13

28 Jan '13

Hey there, I'm using the latest dovecot 2.1.13 In the wiki http://wiki2.dovecot.org/Authentication/PasswordSchemes BLF-CRYPT is listed, but i can't use it. "doveadm pw -l" doesn't show it. And i'm unsure about how I am supposed to use the different SHA schemes, since they always output different hashes for the same password. MD5 is working fine, but I'd rather not use it. Is the wiki outdated or how do i get BLF-CRYPT working? thanks, simon

[Dovecot] From Sendmail to Dovecot mdbox, what is missing.
by Torpey List 27 Jan '13

27 Jan '13

Sendmail 8.14.4 dovecot 2.0.9 I have sendmail working and it is sending mail to /var/mail/%u. I have dovecot working in that I can move emails into IMAP folders and I can send email through IMAP. I have set up dovecot to use mdbox based on the following: mail_location = mdbox:~/mail However, I seem to be lacking a key piece of information. Sendmail is sending the mail to /var/mail/%u as a mbox (single file for all emails) format. Dovecot wants to read the mail in mdbox (Multiple messages per file, but unlike mbox multiple files per mailbox.) So the two programs are not working together. So, I cannot get dovecot to read new emails at /var/mail/%u. So I tried changing to the following: mail_location = mdbox:~/mail:INBOX=/var/mail/%u However, dovecot complains that it is NOT a directory. That is because sendmail is sending as mbox format. I have tried two lines of “mail_location” but that did not work. example mail_location = mdbox:~/mail ----> for dovecot mail_location = mbox:INBOX=/var/mail/%u -----> for sendmail I have tried LMTP and dovecot-lda. LMTP – I could not see any difference with this added or not. Dovecot-lda – I have had issues getting it configured. Thanks for any help!

[Dovecot] mbox INBOX out of sync (?)
by Tinguaro Barreno Delgado 26 Jan '13

26 Jan '13

Hello all, I've running a Dovecot's installation for several years without problems but since last system upgrade (Dec 26) I'm facing a kind of sync issue with the /var/mail/ inbox files. We have got mobile and desktops IMAP clients (mostly Mozilla Thunderbird). The problem is that /var/mail/ files (mbox) aren't updated: we can delete mail from clients but they persist in de /var/mail, so the same user can see the mail again from other IMAP client. Logs seems to be correct. Many thanks in advance.

[Dovecot] Dovecot unable to access the shadow file
by kenwood 25 Jan '13

25 Jan '13

I am installing Dovecot-2.1.13 on Slackware 13.37.0 for the first time to replace ipop3d and I have overcome all of the roadblocks as they have developed except this last one and I finally have to say “uncle”. The error messages that are showing up in the dovecot.log are as follows. Jan 24 12:27:27 tux2 dovecot: auth: Error: passwd-file /etc/shadow: open(/etc/shadow) failed: Permission denied (euid=202(dovecot) egid=202(dovecot) missing +r perm: /etc/shadow, we're not in group 43(shadow), dir owned by 0:0 mode=0755) Jan 24 12:27:27 tux2 dovecot: auth: passwd-file(user,192.168.10.2,<pw3xHwzUSQDAqAoC>): no passwd file: /etc/shadow Jan 24 12:27:29 tux2 dovecot: pop3-login: Warning: SSL alert: where=0x4008, ret=256: warning close notify [192.168.10.2] Jan 24 12:27:29 tux2 dovecot: pop3-login: Disconnected (auth failed, 1 attempts in 2 secs): user=<user>, method=PLAIN, rip=192.168.10.2, lip=192.168.10.100, TLS: Disconnected, session=<pw3xHwzUSQDAqAoC> Based on what I have read the only user that should access the shadow file is root. With that in mind I looked at all the configuration and .ext files and the only file I could find that would indicate that root should be checking the shadow file is 10-master.conf. In that file it said the default service auth-worker was root but since it was apparently not working I removed the hash mark and made it explicit. It still didn’t work. As a last resort even though it was not good practice I tried adding user dovecot to the group shadow but that did not work either. It still says dovecot is not in the group shadow even though it is.

[Dovecot] dovecot 2.1.13, proxy and nologin extras field
by Marco Giunta 24 Jan '13

24 Jan '13

Hi at all, in our test environment, I'm playing with dovecot 2.1.13 configured as imap/pop/managesieve proxy. It is configured to authenticate users with ldap and it works very well. Now, I'd like to temporary disable some users's login, because we are moving to another storage, and I wouldn't stop imap service at all. I've found on Dovecot wiki that I could use 'nologin' extra field, but I wasn't been able to get it work. My dovecot configuration is: # 2.1.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.19.1.el6.x86_64 x86_64 ... auth_debug = yes auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no listen = * mail_debug = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 sieve service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } ssl = no ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = prefetch } and my 'dovecot-ldap.conf.ext' is: uris = ldap://ldap.example.it/ dn = "cn=Reader,dc=example,dc=it" dnpass = password base = ou=People,dc=example,dc=it pass_attrs = uid=user,userPassword=password,\ =userdb_home=/var/spool/mail/%1u/%u,uidNumber=userdb_uid,gidNumber=userdb_gid,\ =proxy=y,=host=imap.example.it,\ =nologin=y pass_filter = (&(objectClass=qmailUser)(uid=%u)(accountStatus=active)) With this configuration, all users can login, and log said: Jan 23 09:16:18 localhost dovecot: master: Dovecot v2.1.13 starting up (core dumps disabled) Jan 23 09:16:33 localhost dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Jan 23 09:16:33 localhost dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Jan 23 09:16:33 localhost dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Jan 23 09:16:33 localhost dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Jan 23 09:16:33 localhost dovecot: auth: Debug: auth client connected (pid=3660) Jan 23 09:16:33 localhost dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=imap#011session=PsbzT/DT+gCTeiwf#011lip=192.168.129.109#011rip=192.168.44.31#011lport=143#011rport=53754 Jan 23 09:16:33 localhost dovecot: auth: Debug: client passdb out: CONT#0111#011 Jan 23 09:16:33 localhost dovecot: auth: Debug: client in: CONT#0111#011AHByb3ZhZm0AY2hlcGFsbGU= Jan 23 09:16:33 localhost dovecot: auth: Debug: ldap(prova,147.122.44.31,<PsbzT/DT+gCTeiwf>): pass search: base=ou=People,dc=example,dc=it scope=subtree filter=(&(objectClass=qmailUser)(uid=prova)(accountStatus=active)) fields=uid,userPassword,uidNumber,gidNumber,uid,uid Jan 23 09:16:33 localhost dovecot: auth: Debug: ldap(prova,192.168.44.31,<PsbzT/DT+gCTeiwf>): result: uid=prova uidNumber=2944 gidNumber=650 userPassword={MD5}BjbsTtSovVAs1csswBTI7Q== Jan 23 09:16:33 localhost dovecot: auth: Debug: client passdb out: OK#0111#011user=prova#011proxy#011host=imap.example.it#011nologin#011hostip=192.168.11.136#011pass=password Jan 23 09:16:33 localhost dovecot: imap-login: proxy(prova): started proxying to imap.example.it:143: user=<prova>, method=PLAIN, rip=192.168.44.31, lip=192.168.129.109, session=<PsbzT/DT+gCTeiwf> As you can see 'nologin' field is present in 'passdb' answer, but it doesn't seem to work.

[Dovecot] Permissions when running `dovecot --exec-mail imap`
by Tim Marston 24 Jan '13

24 Jan '13

Hi, I'm running dovecot 1.2.15, on Debian squeeze. /var/mail is owned by group "mail" with permissions "g+rwxs,o=". The mail_privileged_group setting is set to "mail". I am trying to access mail on a remote machine with mutt by tunnelling mutt though ssh and running `dovecot --exec-mail imap` on the mail server. But I frequently get errors in the mail server's logs about not being able to create dotlock files when accessing my INBOX this way. This makes sense -- I'm running dovecot as a regular user, so it isn't able to write to /var/mail as group "mail". I notice that on the dovecot wiki[1] it is suggested that sudo is used to set uid/gid before running `dovecot --exec-mail imap`. But I don't actually want to set the uid, just the gid. And I also have sudo disabled at the moment. So I was wondering about another solution... Would it be acceptable to setgid the dovecot executable and change it's group to "mail" (i.e., `chgrp mail dovecot` and `chmod g+s dovecot`)? Would this pose some kind of security risk? Would this actualy do what I want, or am I missing a bigger picture? Kind regards, [1] http://wiki.dovecot.org/PreAuth -- Tim Marston ed.am

[Dovecot] warning regarding quota and mboxes
by Andreas Meyer 23 Jan '13

23 Jan '13

Hello! We drive mboxes and maildirs and the dovecot-server is running very well and everthing is fine, but I get the following warning in the dovecot-lda-errors.log when a mail is delivered to a mbox. Jan 10 16:29:24 lda(archiv(a)bitcorner.de): Warning: quota: Namespace '' is not Maildir, skipping for Maildir++ quota This is what I defined in the dovecot.conf: mail_home = /var/spool/vhosts/%d/%n mail_location = mbox:~/:maildir:~/ mail_plugins = quota plugin { quota = maildir:User quota quota_rule = *:storage=500MB quota_rule2 = Trash:storage=+10%% } Can I avoid the error above somehow? Namespaces are a bit mysterious for me at the moment. Greetings Andreas
