[Dovecot] POLL: v2.2 to allow one mail over quota?
by Timo Sirainen 12 Feb '13

12 Feb '13

Currently if user is 1MB under quota and someone tries to deliver mail that is over 1MB, Dovecot rejects the mail. But smaller mails aren't rejected probably for days. So user might not even realize that they didn't receive one of the mails. Also having a user "almost over quota" is a rather strange state I think. So what do you think about v2.2 allowing delivery of one last mail even if it brings the user over quota? Except add a limit that if the message size is as much as the user's entire quota limit it wouldn't be added (or 50% or ..?). Also IMAP wouldn't allow this, since user would get an error anyway. I could make this also optional, but if nobody really wants to keep the old behavior there's really no point in adding the option.

[Dovecot] Keyword Flags
by David Woodfall 11 Feb '13

11 Feb '13

I mostly use Mutt to read mail but today I fired up Thunderbird. I have a shell script that looks for new mail, which looks for files in cur/ and new/ ending with the server hostname or a comma. When I fired up TB it seems that all new mail has been given a flag of ,a which I gather means it matches a keyword. My questions are: How did this happen? Did TB do something strange to my mail when it fetched headers? If I change my search parameters to ',[a-z]' will this only catch new mail?

[Dovecot] Disabling auth caching just from one passdb
by Angel L. Mateo 11 Feb '13

11 Feb '13

Hello, I'm using various password databases (one of them is a ldap database, which is the used for users connecting with email clients, and the other with pam, using a pam module integrated with our SSO that is used from our webmail). I would like to disable password caching in my pam database (because 'passwords' provided by our SSO are single use tokens, so caching them has no benefit), but not in the ldap. As far as I know, auth_cache_size is the option to enable caching in all databases. But, is there any option I could use to disable it in a specific password database? -- Angel L.

Re: [Dovecot] Imap process crash: assertion failed: (full_fs_access)
by Joseph Tam 11 Feb '13

Any guess at what would cause this? Feb 7 21:20:53 server dovecot: imap(user): Panic: file mailbox-list-fs-iter.c: line 447 (fs_list_get_roots): assertion failed: (full_fs_access) (Sorry, no core dump) According to my logs, this user couldn't start an IMAP session for a 2 hour stretch for hundreds of connections. Then the problem seemed to have went away. I logged back as that user using a master password, but couldn't recreate this problem. The backtrace is just hex numbers (stripped executables) and I didn't drop privileges, so it refused to drop core, so that's no help. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Moving index files on another disk: no troubles but need more assurances
by Paolo Miotto 11 Feb '13

11 Feb '13

Hi, I'm using dovecot 1.2.15 on debian squeeze with maildir, and I want to move index files out of the mailboxes disk to reduce disk I/O. I need to get the assurance that the switch is completely transparent to my clients (IMAP and POP). I read the wiki documentation and have found this thread (http://dovecot.org/pipermail/dovecot/2009-September/042665.html) which makes me confident, even if it speaks of a older version and only pop3. So I set up a test server, copied a true mailbox and changed mail location from: mail_location = maildir:~/Maildir to mail_location = maildir:~/Maildir:INDEX=/srv/indexes/%1n/%n (all users under the same domain, no need to use %d). On the IMAP side all seems to work fine, new indexes are created in the new location (dovecot.index.log on 1st access, dovecot.index.cache on message manipolation). A test client (evolution) doesn't notice at all, and I have verified via a telnet imap session that UIDs don't change. But I see that when I move the indexes the IMAP HIGHESTMODSEQ response changes and is reset to 1. Can this baffle the clients? On the rfc I don't found reference to this status walking backwards. Need I to verify that all messages have the virtual size (W=nnnn) in the file name (the mailboxes are from a previous cyrus installation, then we switch to dovecot 1.2)? What other test you suggest that checking UIDL on the pop3 side? What happens if the indexes disk disappears (broken or removed from bay or all paths down for FC/iscsi)? Can dovecot 1.2 continue with INDEX=MEMORY as for a disk full? Sorry for the many questions....

[Dovecot] dovecot, postfix and sieve - broken by Ubuntu upgrade 10.10 -> 12.04

[Dovecot] cPanel && Dovecot 2.x
by Marc Jauvin 10 Feb '13

10 Feb '13

I would like to know if dovecot 2.0.9+ can work with cPanel. I know there is a template for it in cPanel 11.34.1, but when I tried to switch to 2.0.9 (from 1.2.17), it didn't work. I didn't put too much time to test it since I only have one live system to test it with, and I have many customers hosted on this server and I cannot disrupt the service. Has anyone been able to make this work, and if so, is there anything special to do other than rebuilding the config with "/scripts/builddovecotconf" ? Thanks.

[Dovecot] GSS-SPNEGO with dovecot and Outlook without Samba
by Julian David Rath 10 Feb '13

10 Feb '13

I am trying to configure a dovecot2 IMAP server to inter-operate with a active directory to authenticate users. The users should be able to login without a password on a domain-joined client(Outlook). Is it possible to do this only with kerberos? I don't want to put a crappy winbind on my mailserver... I already configured my server to authenticate via kerberos(GSSAPI), but Outlook does not even try to authenticate using GSSAPI, it rather uses PLAIN. I would appreciate any help, many thanks in advance.

[Dovecot] dsync timeout?
by Micah Anderson 08 Feb '13

08 Feb '13

I'm using dsync for a regular backup. The backup system flocks so that two cannot run at the same time, which is generally a good thing. The problem is that it seems like dsync sometimes goes off into the weeds and never comes back, leaving a process running and doing nothing forever, hogging the lock and causing my backups never to run again. I just finally figured out that was what was causing the backups not to run on this system was this process: root 17836 0.0 0.0 40888 1600 ? S 2012 0:00 ssh -i /root/.ssh/backmaildir_id_rsa backmaildir@arg /usr/bin/dsync -u foobar server yeah, that has been running since 2012 :( root:/tmp# strace -p 17836 Process 17836 attached - interrupt to quit select(8, [4], [], NULL, NULL very exciting... There doesn't seem to be a timeout in dsync, but perhaps there should be? At this point my only option is to write a cronjob that will look for dsync processes that are over a certain amount of time old and then kill them, after I do that I will need to take a shower because that is a very dirty solution :P thanks for any ideas, or help! micah --

[Dovecot] Dovecot-2.1.14 - pop3 processes always hangs forever - a follow-up

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

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.

[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. I can see this folder in Thunderbird, after clicking error message pops out saying folder dosent exist. -- Adam Maciejewski

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

[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).

[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.

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

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

[Dovecot] speed up dovecot IMAP server
by Bernics Gábor | Penta Unió Zrt. 23 Jan '13

23 Jan '13

Hello, I upgraded my dovecot server (1.2 -> 2.1), from debian backport because it was a little slow (wait 5-6 sec) when I opened some mail (but not every mail). Unfortunately, the mail open speed didn't increase. I think it's an index problem. Have you idea for fixing?

[Dovecot] Fixing bad maildir message sizes
by Richard Platel 23 Jan '13

23 Jan '13

Hello. As stated in my previous message, we have some old compressed maildir messages with incorrect sizes in the filename. These messages cause dovecot 2.x problems. I'm trying to write a script to crawl all our messages, check the actual message size and if necessary, fix the filename. However, when I do this, dovecot gives the message a new UID on next login. If I change the filename in dovecot-uidlist, dovecot still gives a new UID on next login. If I change dovecot-uidlist and delete the index, then the UID is preserved. Re-indexing our millions of mailboxes is not a great solution for us. Is there a good way to fix this?

[Dovecot] question on "doveadm user" and pass/userdb
by Gábor Lénárt 22 Jan '13

22 Jan '13

Hi, I'm about getting to know dovecot in details, I am about the command "doveadm user". The man page shows this example: userdb: jane uid : 8001 gid : 8001 home : /home/jane mail : sdbox:~/sdbox plugins : sieve quota_rule: *:storage=150M It seems to be nice, however I never got this only: ~# doveadm user lgb@office userdb: lgb@office That's all. The dovecot test configuration works otherwise via IMAP/POP3/LMTP nicely. What I guess that the lack of extra information (which would be needed by some scripts of mine, eg for getting user's home easily from shell scripts, as it's hash based, etc) is caused because I don't pass home (and/or other settings) back from userdb and/or passdb. However I do have these in global scope: mail_home = /mailstorage/%Ld/%Ln (yes, this is not hashed at all at the momement but it will be soon) mail_location = maildir:~/Maildir mail_uid = vmail mail_gid = vmail (... and also some global quota stuffs configured in plugin section) Now, I am a bit confused: even with passdb/userdb does not return with user home or GID/UID, dovecot knows these in case of pop3/imap/lmtp access, since these information can be "composed" from those settings. But then, wouldn't it possible so "doveadm user" shows those as well, like lmtp/pop3/imap can resolve those too? Honestly, it's a bit redundant to put needed information into user and pass attrs in every dbs (I have some) when dovecot knows those otherwise ... If I interpret "doveadm user"'s goal wrong (it's just for userdb/passdb query tool nothing more), is there any tool which works in this config, displaying extra information (at least user's home), or should I create some script which just repeats the functionality of dovecot's configured mail_home resolution? Thanks.

Hello, i'm trying to search in mails which are in russian language. Search works fine for UTF-8 mails, but it ignores KOI8-R ones. For english in any mails it also works fine. How i can solve it? I have dovecot 1.2.17 and following config for fts: protocol imap { ..... mail_plugins = quota imap_quota autocreate fts fts_squat } plugin { ... fts = squat fts_squat = partial=4 full=10 }

[Dovecot] Mail logger question
by Hungerburg 21 Jan '13

21 Jan '13

I use Dovecot simply as a way, to provide an e-mail archive for people on the LAN, where they can move messages into from within thunderbird. Mails are stored in a maildir of one system user where all the people know the password of. This was very easy to setup in ubuntu 12. Today I started using the mail_log plugin to provide an audit trail. Now I am looking for a light way, to get the log reflect the different people or principals. One way is, to create users with the same ID in the passwd and shadow files, but I'd rather have them in a separate file, something like a list of aliases for the system user. Can you suggest a simple way, without going virtual users? Below the relevant info on dovecot: $ dovecot --version 2.0.19 $ dovecot -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-35-generic x86_64 Ubuntu 12.04.1 LTS mail_plugins = " fts fts_squat mail_log notify" passdb { driver = pam } plugin { fts = squat fts_squat = partial=4 full=10 mail_log_events = save delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size from subject } protocols = " imap" ssl_cert = </etc/ssl/certs/ssl-cert-snakeoil.pem ssl_key = </etc/ssl/private/ssl-cert-snakeoil.key userdb { driver = passwd } Thank you all -- peter

[Dovecot] %d in configuration file does not work
by Jens Tobiska 19 Jan '13

19 Jan '13

I am trying to set up dovecot in a postfix virtual account/domains setting. In the configuration file I would like to use %d in two places, for: mail_location = /var/mail/vhosts/%d/%n and to specify the location of the respective passwd file: passdb passwd-file { args = /etc/auth/%d/shadow } Looking at the logs, %d is empty while %n works, so dovecot is looking for something in /var/mail/vhosts//myname and /etc/auth//shadow which don't exist. Replacing %d in dovecot.conf with the actual domain name works. So, the quesiton is, why is %d empty, and from where does it take its value?

[Dovecot] [PATCH] LMTP: Permit user IDs containing recipient_delimiter
by Ulrich Zehl 18 Jan '13

18 Jan '13

The Dovecot 2.1 LMTP server currently always strips the address extension from a recipient address (if recipient_delimiter is set), meaning user IDs cannot contain the recipient delimiter character, e.g. "user+foo" is not supported. This was surprising for me, as Postfix behaves differently in this regard: It first looks up "user+foo", and only then "user". The attached patch works for me and brings Dovecot's behavior in line with Postfix. Please let me know what you think about it.

[Dovecot] possible: two private namespaces with different quota?
by Steffen Kaiser 17 Jan '13

17 Jan '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, in thread "how to setup different quota for multiple namespaces" I tried to get an additional, private namespace "archive" with yet another quota. Every message, regardless if delivered to INBOX or archive, counts for both namespaces, the default one and the archive one. Furthermore the dict records the quota of the archive namespace as user "ns=archive". Because the quota_rules does not accept "*", I see no way to have two or more private quota roots. Could one improve quota_root_rule_find(struct quota_root_settings *root_set, const char *name) { struct quota_rule *rule; array_foreach_modifiable(&root_set->rules, rule) { char *p = strchr(rule->mailbox_name, '\0'); if(p && p > rule->mailbox_name + 1 && p[-1] == '*' ) { /* compare box* */ if(memcmp(rule->mailbox_name, name, p - rule->mailbox_name - 2) == 0) return rule; } else if (strcmp(rule->mailbox_name, name) == 0) return rule; } return NULL; } So one could add a relative rule for the default private namespace.

[Dovecot] Benchmarking: Dovecot vs Courier. Courier wins as POP3 server
by Alexandr Sabitov 17 Jan '13

17 Jan '13

Hi All, I have compared Dovecot performance to Courier and it appears that as a POP3 server Dovecot is slower in 2 times but as an IMAP server it is faster in 1.5 times. The same node (16CPUs), testing time is 30 min, please see results and dovecot configs attached. Benchmark software is MStone used by Sendmail Inc so is is quite reliable. I do not see anything else to tweak in Dovecot to increase POP3 performance. Can we all have some tips to improve it please ? This is how my Dovecot set up: (LDAP user) -> Dovecot Director -> (Master user) -> Dovecot Dovecot Director: dovecot-shared-4:~# /usr/local/dovecot/bin/doveconf -n -c /usr/local/dovecot/etc/dovecot/dovecot-proxy.conf # 2.1.12: /usr/local/dovecot/etc/dovecot/dovecot-proxy.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.6 auth_debug = yes auth_mechanisms = plain login cram-md5 ntlm auth_verbose = yes base_dir = /var/run/dovecot-proxy default_internal_user = webmail director_mail_servers = 192.168.100.102 director_servers = 192.168.100.101 disable_plaintext_auth = no doveadm_password = blah doveadm_proxy_port = 9292 instance_name = dovecot-proxy listen = 192.168.100.101 log_path = /var/log/dovecot-proxy.log login_greeting = Dovecot Proxy ready. mail_location = maildir:~/ passdb { args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } service auth-worker { user = webmail } service auth { client_limit = 2400 } service director { fifo_listener login/proxy-notify { mode = 0666 } inet_listener { port = 9191 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service doveadm { inet_listener { port = 9292 } } service imap-login { executable = imap-login director inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } service imap { service_count = 0 } service lmtp { inet_listener lmtp { port = 24 } } service pop3-login { executable = pop3-login director inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3 { service_count = 0 } ssl_cert = </usr/local/dovecot/ssl/dovecot.pem ssl_key = </usr/local/dovecot/ssl/dovecot.pem userdb { args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol imap { mail_max_userip_connections = 100 } protocol doveadm { auth_socket_path = director-userdb } Dovecot (back-end): dovecot-shared-4:~# /usr/local/dovecot/bin/doveconf -n # 2.1.12: /usr/local/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.6 auth_debug = yes auth_master_user_separator = * auth_mechanisms = plain login auth_verbose = yes base_dir = /var/run/dovecot/ default_internal_user = webmail disable_plaintext_auth = no doveadm_password = blah listen = 192.168.100.102 log_path = /var/log/dovecot.log mail_fsync = always mail_location = maildir:~/ mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " quota fts fts_lucene" mmap_disable = yes namespace { inbox = yes location = prefix = INBOX. separator = . } passdb { args = /usr/local/dovecot/etc/dovecot/passwd.masterusers driver = passwd-file master = yes pass = yes } passdb { driver = static } plugin { fts = lucene fts_lucene = whitespace_chars=@. quota = maildir:User quota } service director { unix_listener director-admin { mode = 00 } } service doveadm { inet_listener { port = 9292 } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_limit = 20 process_min_avail = 8 } service imap-postlogin { executable = script-login /usr/local/dovecot/bin/imap-postlogin.sh user = webmail } service imap { executable = imap imap-postlogin } service lmtp { inet_listener lmtp { port = 24 } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } process_limit = 20 process_min_avail = 8 } service pop3-postlogin { executable = script-login /usr/local/dovecot/bin/pop3-postlogin.sh user = webmail } service pop3 { executable = pop3 pop3-postlogin } ssl_cert = </usr/local/dovecot/ssl/dovecot.pem ssl_key = </usr/local/dovecot/ssl/dovecot.pem userdb { args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol imap { mail_plugins = " quota fts fts_lucene imap_quota" } Best Regards, Alexandr Sabitov Netregistry

[Dovecot] dovecot-2.2.beta1: do not removes e-mail with enabled replication

Hello. I'm created two installations of dovecot-2.2.beta1 with identical config. Without replication each server works good. With replication enabled every changes are replicated between these ones. When I probe remove or move some email in another folder it is disappears and reappears again and again in source folder and appears in destination folder.

[Dovecot] FTS what to use ?
by Erik Colson 16 Jan '13

16 Jan '13

Hi I'm currently using dovecot 2.0 with squat fts which does a nice job. However I'm thinking about upgrading to dovecot 2.1 and the wiki isn't clear about which fts can or should be used with it. Is squat support dead ? As the wiki mentions that the config syntax is obsolete, I'm not sure if squat is obsolete also ? If not, what is the new syntax ? But in the case squat is dead.. what is the recommended alternative nowadays ? I don't really need substring search, but it is a nice thing to have. PS : I will be using dovecot 2.1 with maildir thanks -- erik

My AD Accounts ar stored in two Subfolders ou=Bischoff Benutzer LTT, dc=bischoff-ltt, dc=local ou=Bischoff Benutzer Nbg, dc=bischoff-ltt, dc=local If i use "base = ou=Bischoff Benutzer LTT, dc=bischoff-ltt, dc=local" everything is fine but users from "ou=Bischoff Benutzer Nbg" will not work. Thats ok so far. But when i use "base = dc=bischoff-ltt, dc=local" none user will be found even if i use "scope = subtree". Postfix has no problem with the base set to "dc=bischoff-ltt, dc=local". Ldapsearch has no problem too. I use Version 2.1.12 on Gentoo Linux with a 2003R2 AD Is scope=subtree broken in Dovecot? Must I set some special parameters for Windows AD? My Config: hosts = 192.168.1.98 dn = bischoff-ltt\ldapsearch dnpass = xxxxx auth_bind = yes ldap_version = 3 scope = subtree base = dc=bischoff-ltt, dc=local #base = ou=Bischoff Benutzer LTT, dc=bischoff-ltt, dc=local #base = ou=Bischoff Benutzer Nbg, dc=bischoff-ltt, dc=local user_attrs = =home=/var/dovecot/%Ln/,=mail=maildir:/var/dovecot/%Ln/ user_filter = (&(ObjectClass=person)(sAMAccountName=%u)) pass_filter = (&(ObjectClass=person)(sAMAccountName=%u)) Thanks for Help Marcus

[Dovecot] Define custom ldap libraries when building Dovecot
by Nikolaos Milas 15 Jan '13

15 Jan '13

Hello, I would like to compile Dovecot using custom ldap libraries, located at a particular custom system location. How should I alter the config process to specify that the include dir is "/usr/local/openldap/include" and the lib dir is "/usr/local/openldap/lib64" and not the standard ones (/usr/include/ and /usr/lib64/ respectively) on RHEL/CentOS 5 (x86_64). Note that all of the above files/folders exist on the file system at the same time. The idea is to build dovecot against current openldap v2.4.x libraries and not against the available (by the OS) ancient openldap v.2.3.x libs. Please, advise. Thanks, Nick

[Dovecot] Zlib maildir reindex bug?
by Richard Platel 14 Jan '13

14 Jan '13

Hi Running dovecot 2.1.7 (from debian repo). We have some old compressed maildir messages with the wrong S= size in the filename (our fault). If I delete index files, log in to the mailbox and try to FETCH the bad message, dovecot complains about the incorrect message size, attempts to fix the filename and disconnects the client. However, it changes the filesize to the size of the message on disk, not the message's uncompressed size. For subsequent clients, the FETCH works, but dovecot logs an error (and maybe re-indexes the mailbox?) and the message UID changes.

[Dovecot] sieve reject to wrong address?
by Felix Rubio Dalmau 14 Jan '13

14 Jan '13

Hi all, I have succeed in setting up postfix (to send/receive emails), dovecot to access the folders via IMAP, all using TLS and sieve under dovecot to manage filters. I have also set up a sieve rule to reject those mails whose size exceeds 2 MB... and I'm really proud of everything, because it is my first time!! However, when rejecting the mail, instead of sending a mail saying "I'm sorry blah, blah, blah" to the originary sender, it is sent to the final recipient (that is, me). Do you know how to solve it? Is it a problem from sieve or dovecot? I think is some misconfiguration of my dovecot installation, because the sieve rule is: ################ if size :over 2M { reject text: Ho sento, no accepto cap correu de mes de 2MB de tamany. Sisplau, puja els fitxers mes grans a un servidor i envia'm un link. Gracies. I'm sorry, I do not accept mail over 2 MB in size. Please upload larger files to a server and send me a link. Thanks. . ; } ################ dovecot log looks like: Jan 14 17:34:16 server dovecot: lda(felix@server): sieve: msgid=<201301141734.16203.felix@server>: rejected message from <felix@server> (reject) Jan 14 17:34:16 server postfix/cleanup[2011]: 2B59CB59: message- id=<dovecot-1358181256-51155-0@server> Jan 14 17:34:16 server postfix/pipe[2012]: 311AF4E0: to=<felix@server>, relay=dovecot, delay=1, delays=0.81/0.02/0/0.19, dsn=2.0.0, status=sent (delivered via dovecot service) Thank you! -- Felix Rubio Dalmau

Hello, Due to a misstake I got many duplicate emails in my inbox folder. They are stored in maildir format, so my initial thought was do simply md5sum the mail files and remove the duplicates. This doesnt work because the mails has differinf uids. Any other hints? -- Joakim Verona

[Dovecot] Dovecot SASL Client support?
by Charles Marcus 14 Jan '13

14 Jan '13

Hi all, I seem to recall mention of SASL client support either being added, but can't remember for sure. The wiki says nothing about Client support (now, or in the future)... http://wiki2.dovecot.org/Sasl So - is there support for it now? If not, is it planned for anytime soon? Thanks, -- Best regards, Charles

[Dovecot] load sbub-mailbox
by mourik jan heupink 14 Jan '13

14 Jan '13

Hi, We're about to migrate to dovecot (2.1.7 on wheezy), and I have a question about mail migration. Our 'old' imap mailserver will remain available, and has the same usernames/passwords as our future dovecot mailserver. The question: Is there an easy way to make the old mailboxes available under a subfolder (for example 'oldmail') in the mailboxes on the new mailserver? A bit like mounting an old homedirectory under an 'oldfiles' directory on a new fileserver. This way our users could access/migrate whatever folders they choose themselves, and we would not have migrate all messages to dovecot using scripts like imapcopy, etc. Perhaps using the proxy functionality..? Hope I make myself clear...? Regards, Mourik Jan

[Dovecot] I can not receive any mail
by Felix Rubio Dalmau 14 Jan '13

14 Jan '13

Hi everybody I'm trying to set-up an IMAPS mail server using dovecot (version 2.1.7) with virtual email accounts for my family. I have already ran through the mysql phase of the virtual email configuration (and I'm quite confident it works well, because I can send mails from the server using postfix to gmail, e.g.). However, I am stucked configuring dovecot. I don't know why is it not running properly. The symptoms are: a) When I connect by using my mail client (kmail), I don't get any error. b) When I ask kmail to check what authentication services are supported by the server, I see that it is able to connect to te server by looking to the server log. c) However, Inbox folder does never show up :S d) When I send any mail from gmail to my server, It is always refused under the reason that there is not such user in the machine (I am sure it is), and nothing shows up in the server log. Here is my configuration, just in case somebody can give it a look to help me figure out what's going on :S Thank you very much in advance. # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.6.9-1 x86_64 Debian 6.0.6 ext4 auth_cache_size = 1 M auth_debug = yes auth_mechanisms = plain login auth_verbose = yes auth_worker_max_count = 2 base_dir = /var/run/dovecot/ listen = * log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = Dovecot ready. mail_debug = yes mail_location = maildir:/home/vmail/%d/%n/Maildir mail_privileged_group = vmail 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 = type = private } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster(a)mysite.org protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imaps { port = 993 ssl = yes } process_min_avail = 0 service_count = 1 } service imap { process_limit = 5 } ssl = required ssl_cert = </etc/postfix/ssl/cert.pem ssl_key = </etc/postfix/ssl/cert.key userdb { args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes driver = static } verbose_ssl = yes protocol lda { mail_plugins = sieve } -- Felix Rubio Dalmau

I have a new CentOS 6 server running Dovecot 2.0.9 It has current patches from CentOS. Pasted below are the version and output from dovecot -n When I run mail -s "test" username test <ctrl-D> mail is written to /var/spool/mail/username and not to /home/username/Maildir/ The user's client software, Thunderbird, logs in but since mail is not written to Maildir it thinks there is nothing (see paste below from /var/log/maillog) How do I get sendmail or what ever MTA processes mail to write to Maildir rather than /var/spool/sendmail?

[Dovecot] Anyone using dovecot obox?
by list＠airstreamcomm.net 14 Jan '13

14 Jan '13

Just looking for some input from other users of the obox (object storage) backend from dovecot.fi. - What challenges/problem were you trying to overcome/solve by using obox? - What kind of architecture did you deploy using obox? (e.g. distributed object storage for performance, or distributed for availability, geographic distribution of email services, etc.) - What complexities, single points of failure, documentation omissions can you highlight having deployed the obox storage architecture? - Did the obox backend support your email services as well as you expected or more? - How was your interaction with Doveoct.fi? Thanks in advance.

[Dovecot] Installing Dovecot on Gentoo
by Christian Rößner 14 Jan '13

14 Jan '13

Hi, I have an already working dovecot server on Ubuntu 10.04 with self-created packages version 2.1.13. This setup is working prefect. Now that I do not wish to continue using Ubuntu (to much work for Upgrading), I decided to switch to Gentoo, as I had made best experiences in the past… I have installed Dovecot on Gentoo and I copied over all my configs and certs and stuff. Also created a user vmail with identical uid/gid and also checked all permissions for the certificate stuff. Dovecot starts. I also can connect to it. But when trying to login, I get errors: ------------------------------------------------------- telnet localhost 143 Trying ::1... Connected to localhost.

[Dovecot] dovecot and cacti (snmp ?)
by mancyborg＠gmail.com 10 Jan '13

10 Jan '13

Hi All, I've put online a postfix+dovecot+mysql+roundcube server that will grow till serving around 1500 accounts. I've installed the usual cacti graphs, plus the beautiful percona suite for mysql's cacti plus some graphs for iops and iostat. I was lurking around for the best solution to graph dovecot usage, the most detailed possible, in order to prevent and foresee problems. I'm finding sparse results, I'm not sure which one is the most current / complete. Do you have any suggestions ? Thank you very much for supporting, regards and have a nice day, Mike

[Dovecot] problems with sieve
by Carsten Laun-De Lellis 10 Jan '13

10 Jan '13

Hi all I am running a simple mail server on ubuntu 12.04LTS with postfix 2.9.3 and dovecot 2.1.10. Since this morning sieve doesn't work anymore. I changed the sieve script forth and back but sieve is not working. I also replaced the sieve file with the backup, but no success. But I can't any error messages in the log files indicating any problem with sieve. The only thing I found is: Jan 10 00:03:26 vmd187 dovecot: lda(carsten.delellis(a)delellis.net): sieve: msgid=<12155505.mmailer335539222(a)fritz.box>: stored mail into mailbox 'Fritz!Box' -- with working sieve Jan 10 13:52:29 vmd187 dovecot: lda(carsten.delellis(a)delellis.net): msgid=<1898328495.2554803.1357821905269.JavaMail.app(a)ela4-app2316.prod>: saved mail to INBOX -- with sieve not working As you can see that after dovecot: lda(carsten.delellis(a)delellis.net): the sieve tag is missing. I have also attached my settings from 90-sieve.conf from dovecot configuration. ## ## Settings for the Sieve interpreter ## # Do not forget to enable the Sieve plugin in 15-lda.conf and 20-lmtp.conf # by adding it to the respective mail_plugins= settings. plugin { # The path to the user's main active script. # sieve = ~/.dovecot.sieve sieve = /vmail/%d/%n/dovecot.sieve # A path to a global sieve script file, which gets executed ONLY # if user's private Sieve script doesn't exist.

[Dovecot] Confused about "Authentication Mechanism" and "Password Schemes"
by Thomas Pries 10 Jan '13

10 Jan '13

Hi, I am currently setting up a Mailserver and decided to use Dovecot as IMAP/POP3-Server. I read the wiki an thought about how to transmit and store the passwords (I want to use a MySQL-database). I want to use encrypted transmission and encrypted storage. The wiki says: "If you want to use only one non-plaintext mechanism, you can store the passwords using the mechanism's own password scheme. " Ok, one secure mechanism is acceptable in my scenario and the wiki gives a list of supported authentication mechanisms and a list of supported password schemes. But I am missing the relation between the two lists, which mechanism expects which storage scheme? Did I overlooked any easy answer (other then "read the RFCs"). Best Regards Thomas

[Dovecot] v2.2.beta1 released
by Timo Sirainen 10 Jan '13

10 Jan '13

http://dovecot.org/releases/2.2/beta/dovecot-2.2.beta1.tar.gz http://dovecot.org/releases/2.2/beta/dovecot-2.2.beta1.tar.gz.sig Lots of fixes since 2.2.alpha1, especially related to dsync. Also dsync now supports syncing private message flags when INDEXPVT is used. Here's again the list of all the major changes in v2.2: * When creating home directories, the permissions are copied from the parent directory if it has setgid-bit set. For full details, see http://wiki2.dovecot.org/SharedMailboxes/Permissions * "doveadm auth" command was renamed to "doveadm auth test" * IMAP: ID command now advertises server name as Dovecot by default. It was already trivial to guess this from command replies. * dovecot.index.cache files can be safely accessed only by v2.1.11+. Older versions may think they're corrupted and delete them. + Implemented IMAP MOVE and BINARY extensions + Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions (by Stephan Bosch). + Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes to be enabled. + Redesigned and rewritten dsync. The new design makes the syncing faster, more reliable and more featureful. The new dsync protocol isn't backwards compatible with old dsync versions (but is designed to be forwards compatible with future versions). + All mailbox formats now support per-user message flags for shared mailboxes by using a private index. It can be enabled by adding :INDEXPVT=<path> to mail location. This should be used instead of :INDEX also for Maildir/mbox to improve performance. + Improved mailbox list indexes. They should be usable now, although still disabled by default. + Added LAYOUT=index. The mailbox directories are created using their GUIDs in the filesystem, while the actual GUID <-> name mapping exists only in the index. + LMTP proxy: Implemented XCLIENT extension for passing remote IP address through proxy.

[Dovecot] Squat FTS plugin not kicking in
by Frerich Raabe 09 Jan '13

09 Jan '13

Hi, I'm running Dovecot 2.1.12 on FreeBSD. I configured Dovecot to use the Squat plugin to provide faster full-text searches. The output of 'dovecot -n' is attached to this mail. However, I just noticed that this plugin doesn't seem to kick in. A raw telnet session seems to confirm this: [..] . SEARCH BODY abcdefg * OK Searched 57% of the mailbox, ETA 0:06 * SEARCH 3425 6254 14710 . OK Search completed (17.262 secs). . SEARCH BODY abcdefg * OK Searched 63% of the mailbox, ETA 0:05 * SEARCH 3425 6254 14710 . OK Search completed (18.651 secs). [..] A SEARCH BODY command doesn't create the dovecot.index.search or dovecot.index.search.uids files mentioned on http://wiki2.dovecot.org/Plugins/FTS/Squat . Also, two subsequent SEARCH BODY invocations don't seem to be any different as far as search time goes. I checked the logs but couldn't see anything which is related, except: Jan 8 21:36:10 imap2 dovecot: indexer-worker(frerich): Indexed 0 messages in INBOX Does anybody have some idea how to get more logging out of index-worker, or whether there's a flaw in my configuration? -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

Hello everyone and Happy 2013! I have a situation -- the first ever I have come across -- which I don't understand. A friend was/is running Postfix and Dovecot - with default configs - nothing was ever changed :-) [root@mail home]# dovecot --version 0.99.11 Anyway, he had a problem with a user mailbox which I wasn't able to diagnose and fix easily. maillog showed: Jan 9 16:11:29 mail imap-login: Login: userx [::ffff:127.0.0.1] Jan 9 16:11:29 mail imap(userx): file lib.c: line 37 (nearest_power): assertion failed: (num <= ((size_t)1 << (BITS_IN_SIZE_T-1))) Jan 9 16:11:29 mail dovecot: child 25217 (imap) killed with signal 6 Jan 9 16:12:03 mail imap-login: Login: userx [::ffff:127.0.0.1] Jan 9 16:12:03 mail imap(userx): file lib.c: line 37 (nearest_power): assertion failed: (num <= ((size_t)1 << (BITS_IN_SIZE_T-1))) Jan 9 16:12:03 mail dovecot: child 25229 (imap) killed with signal 6 Jan 9 16:13:15 mail pop3-login: Login: userx [::ffff:192.168.0.55] Jan 9 16:13:15 mail pop3(userx): file lib.c: line 37 (nearest_power): assertion failed: (num <= ((size_t)1 << (BITS_IN_SIZE_T-1))) My aim is not to fix the above. I have reconfigured both Postfix and Dovecot to use Maildir now and things are fine (not securitywise, but I don't care about that) for now. However, I'd like to migrate old mail for some users, but I don't know how to go about this, given the mailbox format, which I don't understand: Here is what a typical one looks like: [root@mail home]# ls -al johndoe/mail/.imap/ total 24 drwx------ 6 johndoe users 4096 May 27 2010 . drwx------ 3 johndoe users 4096 May 27 2010 .. drwx------ 2 johndoe users 4096 May 27 2010 Drafts drwx------ 2 johndoe users 4096 Jan 9 15:46 INBOX drwx------ 2 johndoe users 4096 May 27 2010 Sent drwx------ 2 johndoe users 4096 May 27 2010 Trash [root@mail home]# ls -al johndoe/mail/.imap/INBOX/ total 180 drwx------ 2 johndoe users 4096 Jan 9 15:46 . drwx------ 6 johndoe users 4096 May 27 2010 .. -rw------- 1 johndoe users 5 Dec 18 2007 .customflags -rw------- 1 johndoe users 10272 Jan 9 15:46 .imap.index -rw------- 1 johndoe users 132774 Jan 9 11:27 .imap.index.data -rw------- 1 johndoe users 5136 Sep 26 2011 .imap.index.log -rw------- 1 johndoe users 9404 Jan 8 18:44 .imap.index.tree [root@mail home]# ls -al johndoe/mail/.imap/Sent/ total 36 drwx------ 2 johndoe users 4096 May 27 2010 . drwx------ 6 johndoe users 4096 May 27 2010 .. -rw------- 1 johndoe users 5 May 27 2010 .customflags -rw------- 1 johndoe users 1608 May 27 2010 .imap.index -rw------- 1 johndoe users 10264 May 27 2010 .imap.index.data -rw------- 1 johndoe users 2576 May 27 2010 .imap.index.log -rw------- 1 johndoe users 1556 May 27 2010 .imap.index.tree [root@mail home]# ls -al johndoe/mail/.imap/Drafts/ total 36 drwx------ 2 johndoe users 4096 May 27 2010 . drwx------ 6 johndoe users 4096 May 27 2010 .. -rw------- 1 johndoe users 5 May 27 2010 .customflags -rw------- 1 johndoe users 1608 May 27 2010 .imap.index -rw------- 1 johndoe users 10264 May 27 2010 .imap.index.data -rw------- 1 johndoe users 2576 May 27 2010 .imap.index.log -rw------- 1 johndoe users 1556 May 27 2010 .imap.index.tree [root@mail home]# ls -al johndoe/mail/.imap/Trash/ total 44 drwx------ 2 johndoe users 4096 May 27 2010 . drwx------ 6 johndoe users 4096 May 27 2010 .. -rw------- 1 johndoe users 5 May 27 2010 .customflags -rw------- 1 johndoe users 1608 May 27 2010 .imap.index -rw------- 1 johndoe users 17950 May 27 2010 .imap.index.data -rw------- 1 johndoe users 2576 May 27 2010 .imap.index.log -rw------- 1 johndoe users 1556 May 27 2010 .imap.index.tree How can I migrate these mails into /home/johndoe/Maildir/ ??

[Dovecot] Dsync didn't updates automatically
by Breno Moreira 08 Jan '13

08 Jan '13

Hi, I'm trying to use the Dsync cluster feature in a simple setup, without director, but I'm having some troubles. First of all, I want to know if this functionality syncs the mailbox when the user receive a mail or only when the dovecot starts? Reading the Dovecot mailing list and the design description for a dsync-replicated Dovecot cluster, I understood that it should sync every time a new mail arrives, but it isn't happening in my system. So, can I do this update automatically? If yes, why is it not working properly? Maybe is my configuration files or maybe I'm confusing the capability of this feature. I'm using Dovecot 2.1.7 included in the Debian Wheezy, with virtual users in a MySQL database, Moreover, I have the following configuration: mail_plugins = $mail_plugins notify replication service aggregator { # give enough permissions for mail processes fifo_listener replication-notify-fifo { user = vmail #mode = 0666 } unix_listener replication-notify { user = vmail #mode = 0666 } } service replicator { # start replication at startup process_min_avail = 1 } plugin { # host1 replicates to host2 #mail_replica = remote:vmail at 10.127.0.2 # host2 replicates to host1 mail_replica = remote:vmail@10.127.0.5 } dsync_remote_cmd = ssh -l vmail %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} service doveadm { # if you're using a single virtual user, set this to # start ssh as vmail (not root) user = vmail } service config { unix_listener config { user = vmail } } The vmail user has rsa id's in both servers, so it can do ssh connections without asking for password. I appreciate your help. Best Regards, -- --------------------------------------------------------------------- Breno Moreira "I have no idols. I admire work, dedication and competence." Ayrton Senna

Hi, I'm unable to get past the subject error trying to setup dovecot 2.1.10 on FreeBSD 6.4: right after login the server closes the connection (testing with telnet) I've tried manualy chown()ing auth-master to 666, so permission issues should be ruled out.

[Dovecot] Access to deleted mails in mdbox storage
by Wolfgang.Friebel＠desy.de 08 Jan '13

08 Jan '13

Hi Timo, we are currently running dovecot 2.1.10 using mdbox storage. Sometimes we get requests from users to restore accidentally deleted mails. If the mails got deleted before a backup was made, such mails could of course not be restored from backup. One option to help users in this respect would be to use the lazy expunge plugin. On the other hand I have seen, that the deleted mails stay intact in the mdbox storage until a doveadm purge has been performed. Therefore without using the plugin it is in principle possible to get access to any deleted mails. As in our case the expunge runs once a week while the backup is done daily we can basically recover all mails ever received. My question: doveadm has currently no command similar to doveadm search or fetch to get to deleted mails. Would it be useful to have such a command? As a proof of concept I wrote a little script to mimic the doveadm fetch as closely as possible given the limited amount of information in the mdbox/storage/m.* files and could indeed get access to deleted mails. Do you regard such a procedure (within doveadm) useful or would you recommend nevertheless using the lazy expunge plugin? I am aware of the fact that this is a solution for mdbox storage only. -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] 2 node dovecot
by Lazy 08 Jan '13

08 Jan '13

Hi, We run dovecot 2.1 on 2 nodes with shared nfs storage. Index files are kept on local disk. Second node is usually used only for email snapshots access. If primary node fails it is configured to take place of the primary imap server. Snapshots are additional namespaces with mail from various points in time. We need a way to easly copy multiple messages from snapshots to current mailboxes. It would be best to make current mailbox available as another namespace so one would simply copy messages from one folder to another. Is it safe ? There will be times when given user is writing to the same nfs based Maildir mailbox from 2 nodes both of them having separate index files. What will happen if already present message gets copied back from the snapshot ? Regards, Michał Grzędzicki

[Dovecot] Director and forwarding LDAP user as Master user
by Alexandr Sabitov 08 Jan '13

08 Jan '13

Hello guys, Would you be able to help me with this little issue. I bet someone has the same config so if you can copy-paste it I will very appreciate it. So main idea is to enable Dovecot director to authenticate a LDAP user with plain or encrypted password and send the user to back-end Dovecot server after the authentication. According to Wiki it is only possible if we use the master user to communicate to the back-end server. On the back-end Dovecot server it is working fine, I can log in as normal user/user_password or as user*masteruser/master_password. The back-end config is: auth_master_user_separator = * passdb { driver = passwd-file args = /usr/local/dovecot/etc/dovecot/passwd.masterusers master = yes pass = yes } passdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } Now front-end: how to get director forward the user to the back-end after authentication on the director? With my director config the user stays on the director all the time: passdb { driver = static args = proxy=y master=masteruser pass=master_password destuser=%u*masteruser } passdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } The only way to forward the user is to setup nopassword=y in args of static passdb but in that case the user will be authenticated on the backend but not on the director... What do I missing ? Please help me Best Regards, Alexandr Sabitov

That hasn't been my experience, but maybe because the non-optional stuff are what I need. For example, my configure for v2.1.x summarizes Install prefix . : /opt/dovecot File offsets ... : 64bit I/O polling .... : poll I/O notifys .... : none SSL ............ : yes (OpenSSL) GSSAPI ......... : no passdbs ........ : static passwd passwd-file checkpassword : -shadow -pam -bsdauth -sia -ldap -sql -vpopmail userdbs ........ : static prefetch passwd passwd-file checkpassword : -ldap -sql -vpopmail -nss SQL drivers .... : : -pgsql -mysql -sqlite Full text search : squat : -lucene -solr A few auth methods, which even if you don't use, is a nice fallback for exceptions or niche caches, no dbs, one mandatory text search method.

Hi, I get "Unknown scheme: BLF-CRYPT" messages if I try to use Blowfish-encrypted passwords, even though it is supposed to be supported. I'm on 2.1.7, Debian Squeeze backports. Do you have any information whether Blowfish is supported with Debian Squeeze crypt(), or is there any other knobs I can turn on to make this algorithm available? Thanks, Kristof

I'm running Debian squeeze i386 (kernel 2.6.32-5-686) and have installed dovecot-imapd and dovecot-common with synaptic and edited /etc/dovecot/dovecot.conf to make sure it has the right protocols and listen instructions.

My reading of all of this is that the dovecot daemon is up and running, that it's listening correctly on 143 and 993 and that I have to do something else to get authorisation even to start the IMAP dialogue with the server. I would like to get it working and locked to SSL only but thought I should start with both unencrypted and encrypted. Can someone help me or point me to the bits of documentation or good web howto or the like that I've missed? TIA, Chris (long term Debian user but it's some years since I last ran my own mail server and I'm a total newby to imap and dovecot)

[Dovecot] wrong authentication for local delivery

Hi all there, I have a postfix/dovecot environment running with ldap authentication. I am able to deliver e-Mails to the internet and also receive them via fetchmail. I have a pure local domain (av.loc). Just for internal purpuse. For all mails where destination is a local mailbox, as for all of the local domain, delivery does not work. Here I can show some logs of such a process: +++ Here the process starts (I have sent an e-Mail to myself).

[Dovecot] dovecot as layer between postfix and thunderbird
by martin svensson 05 Jan '13

05 Jan '13

Hello, im all new to this but feel i want to have a dedicated server to handle my mails from Gmail and Hotmail Basically, i installed SMS, superb Mini Server (based on slackware), and with that default install i got: dovecot, postfix, fetchmail and sendmail. The postfix part seems to work according to a "telnet localhost 25", now i want to procede with dovecot, as i understand it, its the middle layer between (in my case) postfix and thunderbird. What i expect in the very end is a dedicated server who regulary checks and fetches mails, and lets me have all contacts info in the (already up and running) LDAP server. When i start thunderbird, i want it to go grab those mails from my local machine I am, ofcourse all over manpages, HOWTOs, guides and google, but would certainly appriciate further help and points in the right direction My apologises for any weird beginner mistakes in this post

[Dovecot] Non-standard fields?
by Attila Nagy 04 Jan '13

04 Jan '13

Hi, Non-standard fields are mentioned here: http://wiki2.dovecot.org/MailboxFormat/Maildir and they are stated as currently not used. Questions: - am I right that if they will be used, they will be key=value pairs, like fields in the base filename? Like: 1035478339.27041_118.foo.org,S=1000,W=1030:2,S,X=12,A=something - or are they supposed to be flags, like: 1035478339.27041_118.foo.org,S=1000,W=1030:2,S,ABCD - are there any plans to utilize these? Thanks,

[Dovecot] Dovecot Virtual Users with Sendmail
by DormitionSkete＠hotmail.com 04 Jan '13

04 Jan '13

I'm trying to get Dovecot working with Virtual Users and Sendmail on OpenIndiana 151a7. OpenIndiana is the Open Source continuation of OpenSolaris after Oracle tried to kill it off a couple of years ago shortly after acquiring Sun Microsystems. I'm not sure if this is so much a Dovecot problem, as much of a Sendmail problem. I thought this would probably be a better list to start with, though. If not, please let me know. I initially used this Dovecot wiki page to approach this: Simple Virtual User Installation http://wiki2.dovecot.org/HowTo/SimpleVirtualInstall I had to make few minor changes, but I don't think anything significant to the problem I'm having. I can log into SquirrelMail with both virtual users, and with system users. I can send mail to system users from both virtual and system users. I can see the mail that I sent in the Sent Messages folder for both types of users. I just can't send mail to virtual users. When I try to, I get the following message: ERROR: Message not sent. Server replied: Requested action not taken: mailbox unavailable 550 5.1.1 <dswebstore@localhost>... User unknown My configuration info is as follows: systemuser@openindiana:~# /usr/local/sbin/dovecot --version 2.1.12 systemuser@openindiana:~# /usr/local/sbin/dovecot -n # 2.1.12: /usr/local/etc/dovecot/dovecot.conf # OS: SunOS 5.11 i86pc auth_verbose = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_uid = 101 info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_location = mbox:/home/vmail/%u/mail:INBOX=/var/mail/%u passdb { args = /usr/local/etc/dovecot/passwd driver = passwd-file } pop3_uidl_format = %g protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } } ssl = no userdb { args = uid=vmail gid=vmail home=/home/vmail/%u driver = static } protocol lda { postmaster_address = systemuser@localhost } --- My dovecot password file looks something like this, though changed for obvious security reasons: systemuser:{PLAIN} systemuserPASS virtualuser1:{PLAIN}virtualuser1PASS virtualuser2:{PLAIN}virtualuser2PASS --- I read on this page that I needed to put the following in my sendmail dovecot.m4 file: Dovecot LDA with Sendmail http://wiki2.dovecot.org/LDA/Sendmail So this is my dovecot.m4 file, which shows up in my sendmail.cf file after recompiling my sendmail.mc file. ######################*****############## ### DOVECOT Mailer specification ### ##################*****################## Mdovecot, P=/usr/local/libexec/dovecot/dovecot-lda, F=DFMPhnu9, S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP/HdrFromSMTP, T=DNS/RFC822/X-Unix, A=/usr/local/libexec/dovecot/dovecot-lda -d $u --- Finally, this is my sendmail.mc file: divert(-1) # # Copyright (c) 1983 Eric P.

I did not realize you wanted me to actually send you the logs. I thought you only meant for me to look to see if there was anything helpful in them. They do not show much.

[Dovecot] clucene-config.h location
by Dimitri 04 Jan '13

04 Jan '13

By deafult, CLucene installs the clucene-config.h header to /usr/lib/CLucene, but fts-lucene tries to include it from /usr/include/CLucene and fails. Here is how it is fixed in Fedora, for instance: sed -i '/DEFAULT_INCLUDES *=/s|$| '"$(pkg-config --cflags libclucene-core)|" src/plugins/fts-lucene/Makefile.in Indeed, Lucene's pkgconfig file reflects the fact that some headers reside in /usr/lib/CLucene. It would be great if Dovecot used pkgconfig for CLucene. Thanks, Dimitri Mageia Linux packager

[Dovecot] Can't rename mailboxes, any ideas on how to fix?
by Howard Leadmon 04 Jan '13

04 Jan '13

I am running Dovecot 2.1.12 under FreeBSD, and I use Outlook 2010 with imap to connect to my server. I know I used to be able to rename mailboxes, as I do this every year at year end, but when I went to rename some mailboxes the start of this year, blamo up popped the message "CANNOT Renaming not supported across conflicting directory permissions". Then only thing that has really been updated here, is Dovecot itself, as I know the FBSD port updates when new versions are released. Any clues on what may have caused this, or how to best correct it? --- Howard Leadmon

[Dovecot] Dovecot 1.2.7 and Roundcube LIST-EXTENDED commands
by aristidis fesarlis 04 Jan '13

04 Jan '13

Hi all, we use Dovecot 1.2.7 with Maildir, and recently we have set up the latest Roundcube webmail. Inside its config file,it is mentioned that: // By default list of subscribed folders is determined using LIST-EXTENDED // extension if available. Some servers (dovecot 1.x) returns wrong results // for shared namespaces in this case. http://trac.roundcube.net/ticket/1486225 // Enable this option to force LSUB command usage instead. I notice that it seems to work fine, though. We don't have shared namespaces. So my question is: should I change it to LSUB, or will I have problems with my Maildir subscriptions? Thanks

[Dovecot] Dovecot auto subscribe imap public folder
by Marantz 04 Jan '13

04 Jan '13

Hi, I have a public folder up and running. This public folder is shared across the company, but when one user makes a new folder then it is not automatically visible to othe users. They need to subscribe manually. Is there a way to automatically subscribe to this? Kind regards, Robin -- View this message in context: http://dovecot.2317879.n4.nabble.com/Dovecot-auto-subscribe-imap-public-fol… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Folder names
by James Starowitz 04 Jan '13

04 Jan '13

Running a pretty basic setup of imap +pop3 on version 2.1.10 Users are able to create folders in imap that contain "&" the folder on the backend reflects "&-" as it should, you can list folder, but then when you relog into imap then decides it can no longer subscribe to this folder due to invalid UTF characters. Essentially allowing users to lock themselves out by using a very common character in a folder name. Might one of the imap client compatibility plugins in imapd cause this quirkiness ? Should I be coming at this from another direction? Is this a bug?

[Dovecot] Kerberos/GSSAPI auth via .k5login file
by Jörg Herzinger 04 Jan '13

04 Jan '13

Hi, we are currently moving our mailserver to a new server with Dovecot, virtual users in LDAP, Passwords in Kerberos Setup. Everything works fine except for GSSAPI which seems to be a bit buggy. The thing is, that when using a .k5login [1] file it seems that SASL does not get passed the home directory specified userdb. In other words, mails for user1 (see below) are stored in /home/domain.at/user1, while the home dir defined in LDAP is /afs/domain.at/home/user1 (virtual users, so only dovecot, not the system does know about this user and home dir). If I do create a .k5login file in /home/domain.at/user1 with the content "someotheruser(a)DOMAIN.AT", then someotheruser should be able to authenticate himself as user1 via GSSAPI. However, this .k5login file is completely ignored. So it seems to me that the home is not passed on to SASL. If I do add ldap to my nsswitch (for testing only) I additionally have real system users. Now if I create a .k5login in their home defined in LDAP which now also the system knows about everything works just fine. It is still the wrong home since its the one in LDAP and not the one defined by dovecot but at least it shows that our setup is working. See also debug log output below, a failed GSSAPI attempt produces no log output at all. Our System is Debian Wheezy on an amd64 (virtualized), dovecot Version 2.1.7, filesystem is ext4. Everything is tested with Firefox 17.0 on an Ubuntu Lucid client.

[Dovecot] dovecot and avahi
by Robert Moskowitz 03 Jan '13

03 Jan '13

I am trying to figure out if I need avahi on my mail server. I see that POP3 and IMAP are services that Avahi can advertise/discover. Does Dovecot work with Avahi and how do you get POP3 and IMAP advertised? And perhaps more importantly, what clients look for mail services this way? I can't find any information on this in the Dovecot documentation ot googling. Perhaps my search fu is low this year. thank you

[Dovecot] Migration Problem UW-IMAP to Dovecot Maildir
by Michael Sloan 03 Jan '13

03 Jan '13

I've just replaced our ancient (10-year old) mail server running Sendmail/UW-IMAP on Solaris with Postfix/Dovecot 2.1.10 running on Linux on new hardware. I opted to go with virtual users and I didn't want to create system accounts and I might end up hosting another department's mail as well. We have a mix of POP3 and IMAP users, roughly 90 total. The POP3 user mailboxes migrated without a hitch, and the IMAP user mailboxes (in what looks like mbox format) migrated well for the INBOX (found in /var/mail/<username> ) but for those few who managed to create local folders and had mail files in their home directories, those mail files were ignored. Is there any clean way to manage to migrate those folders to the new server now? There were no .mailboxlist or .subscription files anywhere on the old mail server. When I was planning the migration, I tried a variety of the methods listed on the UW-IMAP and generic migration pages including dsync, uw2dovecot.pl, and several others. What appeared to work well at the time was this, although I still have the mail in users' home directories to recover/migrate: /usr/local/bin/doveadm -o imapc_user=$1 -o pop3c_user=$1 -o imapc_password=$2 -o pop3c_password=$2 backup -R -u $1(a)caps.fsu.edu imapc: with this dovecot.conf: # 2.1.10: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.0.13-0.27-pae i686 SUSE Linux Enterprise Server 11 (i586) ext3 auth_mechanisms = plain login disable_plaintext_auth = no imapc_features = rfc822.size imapc_host = p1.caps.fsu.edu imapc_list_prefix = INBOX listen = * mail_location = maildir:/var/vmail/%d/%n/Maildir namespace { hidden = yes list = no location = pop3c: prefix = POP3-MIGRATION-NS/ } 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 = separator = . } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { pop3_migration_mailbox = POP3-MIGRATION-NS/INBOX } pop3_uidl_format = %08Xv%08Xu pop3c_host = p1.caps.fsu.edu service auth { unix_listener /var/run/dovecot/auth-master { mode = 0600 user = vmail } unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = uid=vmail gid=vmail home=/var/vmail/%d/%n allow_all_users=yes driver = static } protocol lda { auth_socket_path = /var/run/dovecot/auth-master log_path = mail_plugins = postmaster_address = postmaster(a)caps.fsu.edu } protocol doveadm { mail_plugins = " pop3_migration" } -- Michael Sloan Systems Administrator FSU Center for Advanced Power Systems sloan(a)caps.fsu.edu

[Dovecot] How To Remove?
by Christian Guastella 03 Jan '13

03 Jan '13

hi, i was looking to setup imap on an old PPC G5 mac i have running as webserver and gateway/firewall machine.. found a dovecot-2.1.7-0.pkg online, and it looked like the typical easy install thing.. someplace called rudix made the package.. not much there in way of instructions, but after i finally figured out where the executable had been stuck i tried it, just to see what kinda config errors would be thrown-up.. got the line below.. /usr/local/sbin/dovecot: Bad CPU type in executable so i'm guessing this means dovecot is intel-cpu only? i don't have the time or patience to read all the unix junk, and get a compiler, do all the make files etc.. been years since i did any of that, and don't want to do it again.. the pkg installer did not come with an uninstaller, and since the install is pretty much useless, is there some list of what it installed so i can get rid of it all? thanks, christian

Re: [Dovecot] Dovecot Virtual Users with Sendmail
by DormitionSkete＠hotmail.com 01 Jan '13

Well our situation is kind of like this: We've been using UW-Imap for 12-15 years, and have loved it. It has a beauty and simplicity to it that is simply wonderful. We're located in a remote part of the Rocky Mountains, and the only internet connection we can get that's faster than a dial-up is a satellite. Lousy upload speeds. Can't host our own sites here. We've been hosting our sites on one of our parishioner's servers for years; but through the years, that's become more and more problematic, and we'd like to do more with it than we currently can. We'd like to set up our own server at our guest house in town. I wanted to use OpenIndiana (Solaris) to take advantage of some of the really amazing features it has. So, I set up UW-Imap on it. Works great. Glory be to our holy God. The problem is, after I got all that working, I went to set up the users for it, and discovered the GUI for creating the users won't allow me to add any users with usernames longer than eight characters. I'm not real dependent on GUI's, and a quick search on the net told me that I can easily add the users with the long user names from the command line. So, I asked on the UW-Imap and on the OpenIndiana list for people's experience about this. Two people said they'd been using long user names on Solaris and BSD for years without any problems, while two others recommended changing to an IMAP server that supports virtual users. One of those recommended Dovecot. So I started looking at Dovecot. I'm not real keen on Sendmail, but to make matters worse, we host our own email on our server here in the mountains. Since we can't get reverse DNS set up for our satellite connection, we have to relay our emails through our parishioner's server, which does have reverse DNS, or else most people's email servers reject them as spam. We also need to be able to send and receive emails from multiple domains. So, I have to be able to figure out how to do both parts of the relay -- our part where we tell our MTA to relay it through the other host, and what will become the server at our guest house to accept those emails and relay them on to the recipients. And the multiple domain issue. I can do all this with UW-Imap and Sendmail, because we've already done all the fighting necessary to get it to work. We've been doing it for years. It just leaves us with the question of whether it's better to go with using UW-Imap on a system that's not designed to support long user names, and possibly getting bit by that, or whether it's better to fight it out trying to learn all this other stuff with a different IMAP server and MTA? Fun! I could probably get Cyrus IMAP to work with Sendmail, because I tried it briefly years ago and already have gone through the grief of figuring that out. But I didn't particularly care for it. One of the things I like most about UW-Imap -- and Dovecot shares this -- is that it's easy to backup, restore inadvertently deleted directories, and to move emails from one server to another. From what I remember, Cyrus wasn't so friendly about that. And it was more difficult to administer than UW-Imap and Dovecot. After reading the 13-page article Ken posted this afternoon, I started looking at Postfix. My impression is, that maybe this might be a good route to try. Dovecot - PostFix - and if I'm going to go through all that, I might as well go with Sieve, instead of Procmail, like we've been using for years. I used Sieve briefly with Cyrus. I've never been thrilled with Procmail. So, with all that background, if anyone would like to share any suggestions or advice, I would certainly appreciate it.

[Dovecot] dovecot crashing?
by Eric 30 Dec '12

30 Dec '12

Happy holidays! I am experiencing an issue when trying to check my mail using IMAP. with Dovecot I have tried checking my mail using a full GUI client (Thunderbird) and telnet. Both times I get disconnected before all of my messages can be downloaded and I see an error in my mail log. Here are the details: [root@cust19-1-prod-domain userqa]# dovecot --version 2.0.9 [root@cust19-1-prod-domain userqa]# dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-164.11.1.el5 x86_64 CentOS release 5.4 (Final) disable_plaintext_auth = no login_trusted_networks = 172.19.136.0 mail_location = maildir:~/Maildir mail_max_userip_connections = 100 mbox_write_locks = fcntl mmap_disable = yes passdb { args = scheme=plain username_format=%n /etc/dovecot/users driver = passwd-file } protocols = imap ssl = no userdb { args = username_format=%n /etc/dovecot/users driver = passwd-file } [root@cust19-1-prod-domain userqa]# i try to check my mail: username@ops1-1-domain:~$ telnet cust19-1-prod-domain imap Trying 172.19.136.223...

The attachment seems small in size: Content-Disposition: attachment; filename="report_amex.xlsx"; size=20527; That means the attachment is 20527 bytes, correct?

Postfix doesn't allow external hosts to connect & relay mail, which explains what you're seeing. Why you're seeing that is better addressed on the postfix list, although you seem to have told postfix to use Dovecot for sasl auth, so maybe, since this is the Dovecot list you should send your Dovecot conf so we can see why it's not working. Also, if you ask on the postfix list you will be asked for the out-put of postfinger which can diagnose sasl problems. Simon

[Dovecot] Update 1.2 -> 2.0 ... INBOX away?
by Martin Rabl 29 Dec '12

29 Dec '12

Hi, yesterday I did an update from dovecot 1.2 to 2.0.19 (Ubuntu 10.04 -> 12.04). After fixing the configuration dovecot startups as it should, but with one error, I don't understand: the INBOX will not be delivered to the Mailclient and will not be filled by "deliver". Instead, dovecot create the two dirs "new" and "cur" directly in "Maildir". the filesystem looks now like: domain/user1/Maildir/INBOX # official INBOX domain/user1/Maildir/new # new mail domain/user1/Maildir/cur # read mail We have searched for an configuration error, but didn't found anything - or did not see one ;-) Maybe there is someone in the list, which see our error in a moment? We are using only imap/s and managesieve, no pop3. Maildir-Layout is FS. Here a snippet of our configuration: ------------ mail_home = mail_location = maildir:~/Maildir:LAYOUT=fs namespace { hidden = no inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace { list = yes location = maildir:%%h/Maildir/:INDEX=%%h/Maildir/shared/%u:LAYOUT=fs prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace { list = yes location = maildir:/srv/vmail/public:LAYOUT=fs prefix = public/ separator = / subscriptions = no type = public } protocol lda { mail_plugins = sieve autocreate } protocol imap { imap_client_workarounds = delay-newmail tb-lsub-flags tb-lsub-flags mail_max_userip_connections = 10 mail_plugins = acl autocreate imap_acl } ------------ Hope you can help! Thank you! Martin

[Dovecot] question
by mattk＠kraner.us 29 Dec '12

29 Dec '12

I just install Dovecot and postfix. When I'm pull dovecot I see in the log that its checking for mail. if a put a test message locally on the server I can pull the message down to my cell phone and other computers. But when I try to a message from gmail or aol it doesn't come in to the server. it always bounces back to the place were I sent it from

[Dovecot] mdbox: more then one altstorage
by Peer Heinlein 29 Dec '12

29 Dec '12

The mdbox-format with the altstorage-feature is quite nice and important. But we're having much more then >> 30 TB of maildata and doing an fsck on huge partitions takes too much (down-) time for our mailsystem. It would be much easier, if Dovecot would be able to use at least THREE storage-paths for his m-Files (and not just TWO like now). Having an altstorage1 and altstorage2, we would be able to move away all mails from on altstorage-mountpoint, we could put this storage-moungpoint into "maintenance" and do an fsck without Downtime for Dovecot. It would be nice having a doveadm-feature to put a altstorage-path in "maintenance-mode", so to move easily away all m-files to other alt-storage-paths and to let Dovecot know not to use this locked partition. Having even more then 3 storage-paths would be nice for huge setups: In this case we could easily use different SMALLER partitions without having just two or three huge partitions > 15 TB. The architecture of the altstorage-system is nice and simple. Wouldn't it be easily possible to look (at least) in three, then just in two places for a m-file? What about a "hash_dir"-system for the storage? What about a configuration-parameter like altstorage_dirs=4 which would mean, that there are 4 storage-mountpoints that could be addressed by "%m": mail_location = mdbox:/vmail/%d/%n/mdbox:altstorage/alt/%m/%d/%n In this case, Dovecot could easily use all existing partitions automatically "round-robin". Or maybe it would be better to tell Dovecot the partitions by: altstorage_dirs_existing = 1,2,3,4 altstorage_dirs_newmail = 1,4 so it would be very easy to tell Dovecot in which partitions he has to look for m-files and where he is allowed to save round-robin new e-mails. With this setup it's easy to put a partition in maintenance mode.

I'm preparing to set up a new set of directors on dovecot-ee-2.1.10.3-1, but would prefer to do this a bit gradually. Will it be OK to set up a ring of directors with 2x dovecot-ee-2.1.10.3-1 and 2x dovecot-2.0.14 ? -jf

[Dovecot] dovecot testinstallation does not tell how to quit
by Robert Moskowitz 28 Dec '12

28 Dec '12

I am having problems logging in with RoundCube, so thought I should see if there were instructions for testing Dovecot login, and sure enough I found some at: wiki.dovecot.org/Testinstallation Well it works, so the problem is probably all RoundCube's, but this wiki page is missing an important line about how to end the Telnet session without killing Telnet! What is the quit/exit command? And please add this to the wiki! Oh, I just guessed it: a logout

[Dovecot] Using -module flag on sieve libs
by Dimitri 26 Dec '12

26 Dec '12

Some modern distros (Mageia, Mandriva) use -no-undefined as a default linker flag for building software. However, undefined symbols are OK if the binary being linked is a plugin. To detect plugins, build system looks for presence of "-module" libtool flag in makefiles. There are two libraries in Pigeonhole that couldn't be linked with -no-undefined: src/lib-sieve/plugins/mailbox/libsieve_ext_mailbox.la src/lib-sieve/libdovecot-sieve.la These modules do contain undefined symbols, but they are not linked against library that provides them. It would be good if corresponding makefiles contained "-module" flags, so that build system could selectively turn off that -no-undefined linker flag. Please see proposed patch (attached). Thanks, Dimitri Mageia Linux packager

[Dovecot] Postfix/mysql/dovecot - Understanding password encryption
by Robert Moskowitz 25 Dec '12

25 Dec '12

I am switching from a fedora/postfix/mysql/couriermail/squirrelmail to Centos/.../dovecot/roundcubemail and adding postfixadmin to the mix. My tutorial before was an earlier version (on F14) of: http://www.howtoforge.com/virtual-users-and-domains-with-postfix-courier-my… Now I am using http://www.campworld.net/thewiki/pmwiki.php/LinuxServersCentOS/Cent6VirtMai… to get me started. I am up to roundcubemail setup and am stumbling to understand what the author here is doing with encrypted passwords, so felt it was time to delve deeper into this. My old setup uses mysql-crypt for the password. MYSQL_CRYPT_PWFIELD password and users could be added to the table with: INSERT INTO `users` (`email`, `password`, `quota`) VALUES ('sales(a)example.com', ENCRYPT('secret'), 10485760); But where this was all simple and no choices, I get to figure out what to do with my dovecot setup. Some of the 'secret' is hinted at in postfixadmin's config.inc.php: // Encrypt // In what way do you want the passwords to be crypted? // md5crypt = internal postfix admin md5 // md5 = md5 sum of the password // system = whatever you have set as your PHP system default // cleartext = clear text passwords (ouch!) // mysql_encrypt = useful for PAM integration // authlib = support for courier-authlib style passwords // dovecot:CRYPT-METHOD = use dovecotpw -s 'CRYPT-METHOD'. Example: dovecot:CRAM-MD5 $CONF['encrypt'] = 'md5crypt'; Where is there information on the different choices and how to choose. Is it as 'simple' as setting up postfixadmin to control the password encryption format then 'inform' dovecot in the dovecot-mysql.conf with default_pass_scheme = MD5-CRYPT Thank you for any pointers.

[Dovecot] Understanding Sockets
by Tim Smith 22 Dec '12

22 Dec '12

Hi, Just trying to consolidate my knowledge of Dovecot and I want to understand various things rather than just key out lines of config in dovecot.conf with the hope of it working. What I wanted to clarify is my understanding the "socket listen" section of the config file. From my limited understanding, this section details how other processes can access the userdb defined in Dovecot. The master socket is used for "internal" processes which is mainly dovecot-lda so that when Dovecot receives mail it knows where to deliver it and client is defined for "external" processes, for example Postfix who would use the info to determine if a user existed. Would you say this is a fair (albeit) dumbed down!!) synopsis of sockets and their purpose? Thanks in advance! Tim

[Dovecot] Non-dovecot user looking for feedback
by Chris Ross 21 Dec '12

21 Dec '12

I've been using UW-IMAPd for neigh on forever (at least since 2001). But, as it's basically stalled, and I'm about to update the hardware that is my mail server, I thought it was time to review existing open-source IMAP servers. Dovecot is the top three in my looking. The other of the top three candidates, because I know of people who've used it, is Cyrus IMAP. So, I should note that my thoughts are "uw-imapd, because I already know how to use it", "Cyrus, because someone I know/trust liked it years ago", and dovecot, because "it seems stable, professional, and to meet all of my needs". I guess the biggest question I have is how files/folders are stored in the filesystem. uw-imapd has a "mbx" format that all of my folders are in, and also has support for mbox and maildir (i think). mbx had some advantages for speed access, which would be unimportant I assume with dovecot's indexes, but IIRC there was also some reason the mbox format coped poorly with multiple clients accessing the same folder at the same time. So, am I right that dovecot supports only the "one big full file" mbox format, and the maildir format? And if so, is it known to allow multiple simultaneous IMAP clients to access and monitor and/or modify the same folder simultaneously? After those questions, it's just a "what do you think the pros and cons of each are?" I know asking in this forum, that I will get most if not all votes for Dovecot. And that's fine, as long as you have specific reasons why it would be better for someone with only a handful of users and minimal time available to administer the systems in question. Thanks! I appreciate any and all feedback. - Chris

[Dovecot] backtrace from postgres dict
by Steffen Kaiser 20 Dec '12

20 Dec '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, since I enabled ACLs I get following backtrace. It looks like that it happens if the ACLs had been changed only. Also, it looks like that it always happens 1 minute after last "dict: Info: pgsql(localhost): Connected to database dovecot", no matter if the user is logged in (and idle) or logged off. Postgres logs: "could not receive data from client: Connection reset by peer" and "unexpected EOF on client connection". Is there some TCP keep alive issue? Postgres is using the "system default" for TCP keep alive. I'm currently testing ACLs via telnet, so the activity with the ACL dict is pretty low, hence, an idle timeout would make much sense. # ../../sbin/dovecot --version 2.1.10 (a4f02f6c0d32) dict connect string: connect = host=localhost dbname=db user=user 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:58 IMAP(user) [22922]: Info: Disconnected: Logged out in=23 out=763 2012-11-28 10:04:41 dict: Panic: file driver-pgsql.c: line 84 (driver_pgsql_set_state): assertion failed: (state == SQL_DB_STATE_BUSY || db->cur_result == NULL) 2012-11-28 10:04:41 dict: Error: Raw backtrace: /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(+0x4857a) [0x7f91f511157a] -> /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(+0x485c6) [0x7f91f51115c6] -> /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(i_error+0) [0x7f91f50e4eaf] -> dovecot2.1/dict() [0x40aa36] -> dovecot2.1/dict() [0x40aa91] -> dovecot2.1/dict() [0x40bed3] -> dovecot2.1/dict() [0x409504] - -> dovecot2.1/dict(sql_db_cache_deinit+0x20) [0x408a60] -> dovecot2.1/dict(main+0x169) [0x405a59] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7f91f4b5cc8d] -> dovecot2.1/dict() [0x404bb9] 2012-11-28 10:04:41 dict: Fatal: master: service(dict): child 22923 killed with signal 6 (core not dumped) - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEVAwUBULXbiGoxLS8a3A9mAQI9Ywf/YItPO4fFT70HcuwCkDXgx0Sn7CEyXu2j +1VzOu3R/TMs1rcxYJIvWiei6Nk3wXywzQl84POadJn61Yf2NuT80nMxwBsBbgio e+0oRE9JNVSjtvX5l7kehEdUDQjqRRKyrhWG9KDlpjWidGsYh7pQg0rDtp3UwG57 HuSBMiBAZ9t9sC2DXjn9wT9vweH3gMIhc/K5U0BLF5JG/K8UAKc5QBUgezjIYzvn KP90TJ4RoZ2vnPzmWfeIsjffRBvvC6UUgWmU02e2H9xJxzF32Nix0s8YWi7G91sH Ei057HW5NsKNDtp6B5fYk+xCpC6ucQiwFSr/ZG+uZCAdtTd2qmf60g== =tQYK -----END PGP SIGNATURE-----

[Dovecot] Problems trying to add dspam delivery to dovecot LDA to working Postfix/Dovecot server. No passdb.
by Brian Jarrett 20 Dec '12

20 Dec '12

Hello list, I'm really hoping someone can point me in the right direction on this. I set up a server using Postfix with LDAP lookups to Active Directory. Postfix delivers to maildir. Dovecot IMAP and POP are working correctly using PAM Kerberos to authenticate via Active Directory. I want to add spam filtering, so I'm trying to set up Postfix to use dspam which is then supposed to use Dovecot LDA to deliver messages to the mailbox instead of having Postfix deliver to the Maildir. I can't get any deliveries to Dovecot LDA to get past passdb lookup. When I run /usr/lib/dovecot/deliver -f bjarrett(a)garfield16.org -d bjarrett(a)metcalfexcavation.com I get: Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: master in: USER#0111# 011bjarrett(a)metcalfexcavation.com#011service=lda Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: password( bjarrett(a)metcalfexcavation.com) passdb doesn't support credential lookups Dec 19 20:57:55 mxserver2 dovecot: auth: Error: static( bjarrett(a)metcalfexcavation.com) passdb doesn't support lookups, can't verify user's existence Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: master out: FAIL#0111 Dec 19 20:57:55 mxserver2 dovecot: lda: Error: user bjarrett(a)metcalfexcavation.com: Auth USER lookup failed Dec 19 20:57:55 mxserver2 dovecot: lda: Fatal: Internal error occurred.

[Dovecot] namespace subscription problem
by Holger Hegmanns 19 Dec '12

19 Dec '12

Hi all, my problem seems to be a cosmetic one (again). According to the docs: subscriptions: "yes" (default) if this namespace should handle its own subscriptions. If "no", then the first parent namespace with subscriptions=yes will handle it. Therefore is no way to create the following scenario: three namespaces (private, shared, public) the private namespace has to handle its own subscriptions the private namespace setup with "prefix = INBOX." the both shared and public namespace setup with "subscriptions = no" cause there is no so called "parent" namespace. Private namespace setup with "prefix = " works fine, but that's not what I want. namespace { type = public separator = . prefix = public. location = maildir:/var/spool/dovecot/vmail/public subscriptions = no } namespace inbox { type = private separator = . prefix = INBOX. inbox = yes } namespace { type = shared separator = . prefix = user.%%u. location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } Any chance that the private namespace can subscribe to shared mailboxes with the principals above? ... Few hours later. Added a default namespace without any prefix: namespace { prefix = separator = . hidden = yes subscriptions = yes } Subscriptions works as expected, but when I telnet to dovecot now the LSUB command shows all boxes beneath the INBOX as well as without the prefix: b lsub "" * * LSUB () "." "Sent" * LSUB () "." "Templates" * LSUB () "." "Trash" * LSUB () "." "Drafts" * LSUB () "." "INBOX.Sent" * LSUB () "." "INBOX.Templates" * LSUB () "." "INBOX.Trash" * LSUB () "."

hi i am planning to migrate from qmail pop3 to dovecot pop3 the number of users on the server is large over 5000 also data volume is large - over 3.5 tb -- ie many users several 1000s of emails in their inbox email clients used are outlook / outlook express / windows mail, etc my questions 1) will the migration cause all the emails on the server to re-download 2) can dovecot be configured to allow only one download at a time - pop3 locking with time out setting that can be customized 3) can dovecot pop3 be configured so that it will allow download of emails only of the last say 15 days ie even if the same pop3 user is configure on another machine it will download only messages of the last 15 days 4) has anybody migrated from qmail pop3 to dovecot pop3 successfully without emails being downloaded again thankyou very much in advance rajesh

[Dovecot] Upload / migrate old mails: iPhone shows oldest mails first

hi, I've got a very strange behavior: I uploaded old mails from a local folder (thunderbird / osx) to my Dovecot (Debian Squeeze) and now, the iphone (ios6) show the oldest mails first. The only thing I can imagine is, that Dovecot got from Thunderbird the newest mails first and last the old mails, so that in the last mdbox are the old one. So, if it is correct, how can I fix it? cu denny

[Dovecot] Too many imap connections in state "idling"
by 3.listas＠adminlinux.com.br 19 Dec '12

19 Dec '12

Hi, I have a "Ubuntu12.04 + dovecot-2.0.19" configuration in my server. My mailbox server is shared by ~ 10k domains. It works fine with ~50k accounts. On average, my server has about 6K simultaneous imap connections during office hours. But I've noticed that this server has an average of approximately 4k connections in state "idling". On other Dovecot servers the average connections in state "idling" is only 10%. My doveconf -n: http://thiagoh.prv.digirati.com.br/doveconf-n.txt Can someone help me? Thanks -- Thiago Henrique adminlinux.com.br

[Dovecot] Dsync help, new attempt
by Torbjorn Astlind 19 Dec '12

19 Dec '12

I observe that dsync fills Maildir correctly incl. cur, if I delete Maildir just before dsync runs. Can the failed mbox to Maildir conversion be caused by dovecot creating Maildir automatically if a client connects to dovecot? Should dovecot be shutdown when running dsync? All the best, Torbjörn 9. dsync help?

Message-ID: <50C600B4.4040603(a)dbb.su.se> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Hi all, I have dovecot serving aprox 200 users through mbox, but the time has come to migrate to a new server, and to use Maildir. Using rsync from the old server I get all user data, i.e /home/*, and inboxes i.e /var/mail/* to a new server. This has worked well for some time as backup. The dsync should convert everything to Maildir, and it does... to an extent. (linebrakes for easy viewing) What I see, is that often, the /home/mail/xxx is NOT resulting in /home/xxx/Maildir/cur All mailboxes from /home/xxx, are properly converted to /home/xxx/Maildir/.name_of_ box Am I misunderstanding something? I get it to work sometimes if I delete the ~/Maildir completely before doing the dsync.

[Dovecot] Advice on sieve vacation for aliases
by Marcio Merlone 19 Dec '12

19 Dec '12

Greetings, I have a working mail server with sieve 1:1.2.9-1ubuntu6.5 working just fine. My commercial dept. has asked me to set a vacation message for comercial(a)domain.tld, but this is an alias to jhon(a)domain.tld and meggie(a)domain.tld. I have created a sieve_global_path = /etc/dovecot/global.sieve and it works, but not the intended way: it sends two vacation messages, each From: each employee, and not From: comercial(a)domain.tld alias. Is there how to make dovecot send only one vacation message From: comercial(a)domain.tld or will I have to survive with one message from jhon and another from meggie? Also, is there how to have a dovecot.lda-dupes for the alias instead the users? /etc/dovecot/global.sieve: require ["vacation"]; # rule:[Ferias coletivas] if anyof (header :contains "To" "comercial(a)domain.tld") { vacation :days 7 :subject "Férias coletivas de 20/12/2012 a 07/01/2013" text: bla bla bla. ; stop; } Thanks in advance and nice holidays. -- Marcio Merlone

[Dovecot] Adding a parameter to dovecot's deliver to get a meaningful return value
by Cyril RUSSO 18 Dec '12

18 Dec '12

Hi, First, please forgive me as I'm not subscribed to the list. I'm using Dovecot 2 (2.1.7) for serving my local maildir. This maildir is filled by an external process, fetching & merging mails from different sources that's outside this scope (but it's working). Dovecot is thus acting as a MTA, but more as a MDA. I've a web client running on the server, and it connects to Dovecot to get the mails. I've configured this web client & dovecot to use sieve to filter the mails. I know that since Dovecot does not actually deliver the messages, it's not the expected behavior. Anyway, I can use the "deliver" software in your suite for passing sieve's rules on each message in my maildir, and it's almost working. I've a cron job that run deliver on each message of my maildir, but I'm a bit puzzled now. Basically, I'm not able to figure out if a message was matched by a sieve filter or not. I'm a bit disappointed by two things: 1) Sieve's reject doesn't make "deliver" to return an error, so a sieve rule chain ending in "reject" can't be detected from my cron's script. I wonder it's due to the step deliver is supposed to be run (after a mail is already accepted). 2) "deliver" doesn't have a method to find out if it processed the given mail as input. Basically, would it be possible to either add a parameter to "deliver" (for example: "--fail-on-discarding") so it would fail if the sieve rules discard or reject (/ereject) the mail ? That way, I could detect the failure in my script, and know that I don't need to delete the initial mail since it was not filtered. Or, thought differently, I wonder if "deliver" could open a socket/pipe/file whatever, and write the number of processed mails in there (or using a "--return-processed-mail"), so a sieve rule ending with "delete", would be detectable by my script. Best regards, -- Cyril

[Dovecot] Clear-text ldap passwords: {CLEAR} scheme?
by Kristof Bajnok 18 Dec '12

18 Dec '12

Hi, if I read the documentation correctly, the clear-text password storage scheme in Dovecot is called PLAIN. Unfortunately, in Sun LDAP Directory Server I have to specify them as "{CLEAR}" [1]. Is it somehow possible to make Dovecot recognise "{clear}foobar" passwords as plaintext? Now I get: auth: Error: ldap(username): Unknown scheme clear Thanks, Kristof [1]: http://docs.oracle.com/cd/E19850-01/816-6699-10/confattr.html#passwordStora…

[Dovecot] dovecot-lda (2.1.12) segfaults
by Joseph Tam 18 Dec '12

18 Dec '12

We uograded our dovecot from version 2.1.10 -> 2.10.12, but within the first hour of use, dovecot-lda would segfault during delivery. This left a lock file lying around causing the user's mail readers to hang; much hilarity ensues. All further deliveries to the same user will result in a crash. The only thing that fixes this condition is to blow away the user's INBOX cache index. Reindexing with "doveadm index" does not fix anything. I've installed a test version with one user's problematic INBOX cache indices and ran gdb dovecot-lda (gdb) run -t testuser </dev/null and it crashes with the following backtrace Program received signal SIGSEGV, Segmentation fault. 0xff2a0440 in mail_cache_header_fields_read (cache=0x5c120) at mail-cache-fields.c:323 323 if (field_hdr->size < sizeof(*field_hdr) + (gdb) bt #0 0xff2a0440 in mail_cache_header_fields_read (cache=0x5c120) at mail-cache-fields.c:323 #1 0xff29e8bc in mail_cache_compress_locked (cache=0x5c120, trans=0x63ce8, unlock=0xffbfeeef) at mail-cache-compress.c:361 #2 0xff29efd0 in mail_cache_compress (cache=0x5c120, trans=0x63ce8) at mail-cache-compress.c:489 #3 0xff2a3df4 in mail_cache_transaction_compress (ctx=0x5dac0) at mail-cache-transaction.c:180 #4 0xff2a4084 in mail_cache_transaction_open_if_needed (ctx=0x5dac0) at mail-cache-transaction.c:241 #5 0xff2a6e60 in mail_cache_field_want_add (ctx=0x5dac0, seq=1, field_idx=12) at mail-cache-transaction.c:1048 #6 0xff27e8e8 in index_mail_parse_header_register_all_wanted (mail=0x5e6b0) at index-mail-headers.c:175 #7 0xff27ec90 in index_mail_parse_header_init (mail=0x5e6b0, headers=0x0) at index-mail-headers.c:230 #8 0xff27f5c8 in index_mail_cache_parse_init (_mail=0x5e6b0, input=0x63760) at index-mail-headers.c:376 #9 0xff2299cc in mbox_save_get_input_stream (ctx=0x5dde8, input=0x62ed0) at mbox-save.c:411 #10 0xff22a084 in mbox_save_begin (_ctx=0x5dde8, input=0x62ed0) at mbox-save.c:520 #11 0xff24e9c0 in mailbox_save_begin (ctx=0xffbff514, input=0x62ed0) at mail-storage.c:1652 #12 0xff23f138 in mail_storage_try_copy (_ctx=0xffbff514, mail=0x54cd8) at mail-copy.c:68 #13 0xff23f23c in mail_storage_copy (ctx=0x5dde8, mail=0x54cd8) at mail-copy.c:93 #14 0xff24ec28 in mailbox_copy (_ctx=0xffbff670, mail=0x54cd8) at mail-storage.c:1721 #15 0xff24ec98 in mailbox_save_using_mail (ctx=0xffbff670, mail=0x54cd8) at mail-storage.c:1730 #16 0xff388070 in mail_deliver_save (ctx=0xffbff8a8, mailbox=0x13fe8 "INBOX", flags=0, keywords=0x0, storage_r=0xffbff83c) at mail-deliver.c:317 #17 0xff38869c in mail_deliver (ctx=0xffbff8a8, storage_r=0xffbff83c) at mail-deliver.c:403 #18 0x00012d08 in main (argc=3, argv=0xffbff964) at main.c:434 I dumped the value of field_hdr, and it has some bogus value (gdb) p field_hdr $1 = (const struct mail_cache_header_fields *) 0x20 Other observations - blowing away the indices does not fix it permanantly.

[Dovecot] NFS, deleting folder issue

Hi there, I use dovecot on a server with some Nightmare File Systerm (aka NFS) storage. When I delete a folder, its content gets deleted, but the folder itself does not.

Please don't suggest that I should not use NFS! I know that, and I don't really like NFS, but I have no other choice. Catalin Petrescu <catalin.petrescu gmail com>

[Dovecot] Manually creating dovecot- files after isync/mbsync mirror
by Dale Gallagher 18 Dec '12

18 Dec '12

Hi everyone I'm using isync 1.0.5 patched to do recursive folder listing and mirroring mail from an external party's IMAP server to a local Maildir, which will be accessed by Dovecot 2.0.9. In order to prevent IMAP clients from re-downloading their mail, when connecting to Dovecot, I'm busy writing a script to generate appropriate dovecot-uidlist and dovecot-uidvalidity files, per Maildir. isync stores the uid in the filename, so that's extractable, per message, and the uidvalidity and current max uid are stored in a file .uidvalidity, in each Maildir. I've read the docs here: http://wiki2.dovecot.org/MailboxFormat/Maildir Regarding the dovecot-uidlist header (first line) - I've tried to search for and figure out what exactly is meant by the "mailbox global uid" and once I do, how to manually generate the 128 bit hex variation of it? Could someone elaborate on this, please. How would omitting the global uid field, beginning with G, affect remote clients' syncing of mail? Is this field mandatory? I also see that Dovecot's uidvalidity is of the form 4df8a4e2, whereas isync uses an integer. I'd appreciate it if someone could elaborate on what Dovecot uses and whether I can convert one to the other? I'll post the full solution, once complete, and working. Thanks. Dale

Re: [Dovecot] Automatically Cleaning Kerberos Credential Cache Files

Ben Morrow writes: > In any case, it's likely that the delivery process looks in the user's > home directory even if delivery is to a separate mail spool, unless > you've taken steps to prevent this. I can confirm this. I think the reason is that dovecot changes to the user's home directory so that it has a place to dump core. This causes problem for my setup since I user per-user NFS mounts, so a delivery to an internal mailing list caused hundreds of NFS automounts. I patched this behaviour out, but there is probably a more elegant solution (unset MAIL_STORAGE_SERVICE_FLAG_ENABLE_CORE_DUMPS? How?).

[Dovecot] Removing configured SSL certificate file from disk while Dovecot is running spams syslog
by Nils 18 Dec '12

18 Dec '12

Hi! [root@mikan ~]# dovecot --version 2.1.12 When I remove the SSL certificate from disk while Dovecot is running, it spams syslog with the following log message over and over: Dec 6 17:41:41 mikan dovecot: config: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 12: ssl_cert: Can't open file /etc/ssl/private/dovecot.pem: No such file or directory Dec 6 17:41:41 mikan dovecot: config: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 12: ssl_cert: Can't open file /etc/ssl/private/dovecot.pem: No such file or directory Dec 6 17:41:41 mikan dovecot: config: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 12: ssl_cert: Can't open file /etc/ssl/private/dovecot.pem: No such file or directory [...] Reporting that the certificate went away is fine and useful, but spamming the syslog over and over with hundreds of entries per second(!) is annoying. :( I know what I'm doing, so reporting it once per connection attempt or something is enough. Even if Dovecot just decides to terminate, that would be fine. But a denial of service attack on syslog is not nice. Configuration output follows below.

[Dovecot] Documentation of Redis and Memcache Backends
by Urban Loesch 18 Dec '12

18 Dec '12

Hi, in the release notes of 2.1.9 I read that dovecot supports memcache and redis backends for userdb/passdb authentication. This is very interesting for me and should reduce queries and database load of our mysql servers. My idea is to use memcache or redis in our IMAP/POP3 proxies in front of our backend servers. So I would like to try out if it's possible to store proxy information of our backends. For example the backend ip adress. But in the wiki I found only a few configuration settings for redis backend. http://master.wiki2.dovecot.org/AuthDatabase/Dict Also the mentioned example config file "dovecot-dict-auth.conf.ext" with full list of configuration options does not exits in the source of 2.1.11. Have you any idea where I can find the full info or any howtos? Many thanks and regards Urban

[Dovecot] Error: unlink_directory(.../lucene-indexes) with doveadm index
by Fred Kilbourn 18 Dec '12

18 Dec '12

Hi, Per discussion on this previous thread: http://dovecot.org/pipermail/dovecot/2012-October/068849.html I am updating search indexes on all my mailboxes via a nightly cronjob that runs: doveadm index -A '*' The problem we're running into is that random mailboxes will throw the following error during the update (sanitized to conceal actual domain name): doveadm(user(a)domain.com): Error: unlink_directory(/var/spool/mail/domain.com/user/sdbox/lucene-indexes) failed: Permission denied We have around 250 domains on the server, with a handful of mailboxes on average in each domain. We get this for a varying number of total mailboxes (1 to 6 every night). It is common for the same mailbox to show up a few days in a row and then stop throwing the error. The script is running as root, so there shouldn't be any file level permissions. Any thoughts on the root cause of these errors? What can I provide to help further diagnose? Thanks, Fred Kilbourn

[Dovecot] Dovecot version 1.2.17
by Philip Coackley 18 Dec '12

18 Dec '12

Hello, I am currently performing retrospective upgrades to an old ubuntu 9.10 Karmic Kola server. I need to upgrade dovecot 1.1.11 to 1.2.17 then to 2.0 etc. I have downloaded the binaries and run ./configure make make install. Dovecot compiles OK however I can not get the ./configure options to install at the following locations: executable: /usr/sbin/ config: /etc/dovecot/ Question: What are the ./configure options to do this? What are the ./configure options used to create the executable for unbuntu? (especially 9.10 if different). Reason for upgrade is auth-login errors every 2-3 weeks with 1.1.11 - looking at the release descriptions, this should fix this and the memory leaks! Phil Coackley

I still run using mbox, and have not had a problem with corruption, however, this is probably owing to our modest IMAP demand and careful coordination of file locks among all the different MUAs. You're better off with Maildir and other formats, that are better designed for simultaneous access. There are other good reasons to switch formats. Dovecot also supports its own mdbox/sdbox for high performance: its a hybrid that tries to incorporate the best of both words. More info http://wiki2.dovecot.org/MailboxFormat > After those questions, it's just a "what do you think the pros and cons > of each are?" I can't speak to the other software you are looking at, but two factors I found to be particularly good: - flexibility: you can get almost every oddball setup to work. Migration from uw-imapd is fairly easy, but then again, uw-imapd didn't have a lot of knobs to turn. Plugins are available that extends its functionality. - support: this mailing list is great, and Timo is an absolute wizard in getting bugs fixed.

[Dovecot] need help with dovecot-lda
by Andreas Meyer 16 Dec '12

Hello all! Some month ago I upgraded our dovecot installation from version 1.0.5 to version 2.1.7 without having any trouble. Postfix is delivering email directly per virtual transport to the maildirs and mailboxes of the users in /var/spool/vhosts/domains/.... Now I want to use dovecot-lda and created a new entry in the master.cf of postfix. dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/dovecot-lda -f ${sender} -d ${recipient} It is not clear to me, how the dovecot-lda is started bei dovecot and you it finds the socket dovecot postfix created. The dovecot.conf looks like this; # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.22.5-31-bigsmp i686 openSUSE 10.3 (i586) ext3 auth_verbose = yes disable_plaintext_auth = no log_path = /var/log/dovecot1 mail_location = mbox:/var/spool/vhosts/%d/dovecotprivate/%n:INBOX=/var/spool/vhosts/%d/%n !include /etc/dovecot/conf.d/*.conf passdb { args = /etc/dovecot/passwd driver = passwd-file } userdb { args = /etc/dovecot/passwd driver = passwd-file } ssl_cert = < /etc/dovecot/ssl/hostcert.pem ssl_key = < /etc/dovecot/ssl/hostkey.pem #verbose_ssl = yes plugin { quota = maildir:User quota quota_rule = *:storage=500MB # 10% of 1GB = 100MB quota_rule2 = Trash:storage=+10%% # 20% of 1GB = 200MB # quota_rule3 = Spam:storage=+20%% autocreate = Trash autocreate2 = Drafts autocreate3 = Sent autosubscribe = Trash autosubscribe2 = Drafts autosubscribe3 = Sent } I set soft_bounce = yes in main.cf of postfix and delivery of mail fails with Dec 14 16:13:34 delta postfix/virtual[14082]: BBC0F1B31294: to=<xyz(a)anup.de>, relay=virtual, delay=395, delays=395/0.01/0/0.13, dsn=4.1.1, status=SOFTBOUNCE (unknown user: "xyz(a)anup.de") This is the relevant part of the main.cf: dovecot_destination_recipient_limit = 1 virtual_mailbox_domains = anup.de bit-corner.de bitcorner.de baubetreuung-meyer.de saxelektro.de virtual_mailbox_base = /var/spool/vhosts #virtual_mailbox_maps = hash:/etc/postfix/vmailbox #virtual_minimum_uid = 100 #virtual_uid_maps = static:5000 #virtual_gid_maps = static:5000 virtual_mailbox_limit = 524288000 virtual_transport = dovecot I don't get it right. As far as I understand postfix uses virtual_transport = dovecot and hands the mail over to the socket dovecot. But how does dovecot know where to look for the socket. I am missing somthing but don't know what. Any help is appreciated! Andreas

[Dovecot] Dovecot "sleep" for short snapshots
by Peer Heinlein 15 Dec '12

15 Dec '12

Making consistent backups from Dovecot with mdbox requires a snapshoted filesystem with (at least) a short Downtime for Dovecot. I'd like to avoid killing several thenthousand IMAP-sessions for 60 seconds. Users don't like that... And the admin dislakes that too... What about a "short sleep" mechanism for Dovecot, where all writes are finished and new writes are easily delayed? I'd like to following process: *) "doveadm sleep" puts Dovecot in sleep-Mode: -- All existing writes are finished (before "doveadm sleep" is allowed to exit) -- All new writes are simply delayed -- All readonly-operations could work normally, so users can fetch and read mails *) The the admin can create a LVM-/SAN-snapshot of the filesystems *) "doveadm unsleep" will finish the magic Overall the whole process will take just some seconds. Users will recognize a simple write-delay, but they can work normally and the aren't unconnected at all. If the snapshot is really fast the users won't recognize the whole situation at all.
