[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. (the proxy thats executes the command) (gdb) bt full #0 0x0000003872ee86f3 in __epoll_wait_nocancel () from /lib64/libc.so.6 No symbol table info available. #1 0x0000003873a534b8 in io_loop_handler_run (ioloop=0x2364120) at ioloop-epoll.c:181 ctx = 0x236b080 events = <value optimized out> event = <value optimized out> list = <value optimized out> io = <value optimized out> tv = {tv_sec = 59, tv_usec = 389208} msecs = 59390 ret = <value optimized out> i = <value optimized out> call = <value optimized out> #2 0x0000003873a52488 in io_loop_run (ioloop=0x2364120) at ioloop.c:398 No locals. #3 0x0000003873a3de43 in master_service_run (service=0x2363fd0, callback=<value optimized out>) at master-service.c:544 No locals. #4 0x0000000000413d6e in doveadm_server_flush_one () No symbol table info available. #5 0x0000000000414741 in doveadm_mail_server_user () No symbol table info available. ---Type <return> to continue, or q <return> to quit--- #6 0x000000000040e6bc in doveadm_mail_next_user () No symbol table info available. #7 0x000000000040ed7c in doveadm_mail_cmd () No symbol table info available. #8 0x000000000040f00c in doveadm_mail_try_run () No symbol table info available. #9 0x00000000004162b1 in main () No symbol table info available.

[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?

[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] 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! Sendmail changes FEATURE(`local_procmail', `/usr/libexec/dovecot/dovecot-lda',`/usr/libexec/dovecot/dovecot-lda -d $u') MODIFY_MAILER_FLAGS(`LOCAL', `-f') MAILER(procmail)dnl Here is dovecot configuration [root@nala mail]# dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.14.1.el6.x86_64 x86_64 Scientific Linux release 6.3 (Carbon) auth_mechanisms = plain login mail_gid = mail mail_location = mdbox:~/mail mail_uid = mail mbox_write_locks = fcntl passdb { driver = pam } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_group_events = yes } service auth { unix_listener auth-userdb { mode = 0600 user = mail } } service lmtp { inet_listener lmtp { address = 192.168.1.185 127.0.0.1 ::1 port = 24 } user = mail } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } protocol lda { info_log_path = /var/log/maillog log_path = /var/log/maillog postmaster_address = postmaster(a)torpey.org }

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

26 Jan '13

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

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

25 Jan '13

I am installing Dovecot-2.1.13 on Slackware 13.37.0 for the first time to replace ipop3d and I have overcome all of the roadblocks as they have developed except this last one and I finally have to say “uncle”. The error messages that are showing up in the dovecot.log are as follows. Jan 24 12:27:27 tux2 dovecot: auth: Error: passwd-file /etc/shadow: open(/etc/shadow) failed: Permission denied (euid=202(dovecot) egid=202(dovecot) missing +r perm: /etc/shadow, we're not in group 43(shadow), dir owned by 0:0 mode=0755) Jan 24 12:27:27 tux2 dovecot: auth: passwd-file(user,192.168.10.2,<pw3xHwzUSQDAqAoC>): no passwd file: /etc/shadow Jan 24 12:27:29 tux2 dovecot: pop3-login: Warning: SSL alert: where=0x4008, ret=256: warning close notify [192.168.10.2] Jan 24 12:27:29 tux2 dovecot: pop3-login: Disconnected (auth failed, 1 attempts in 2 secs): user=<user>, method=PLAIN, rip=192.168.10.2, lip=192.168.10.100, TLS: Disconnected, session=<pw3xHwzUSQDAqAoC> Based on what I have read the only user that should access the shadow file is root. With that in mind I looked at all the configuration and .ext files and the only file I could find that would indicate that root should be checking the shadow file is 10-master.conf. In that file it said the default service auth-worker was root but since it was apparently not working I removed the hash mark and made it explicit. It still didn’t work. As a last resort even though it was not good practice I tried adding user dovecot to the group shadow but that did not work either. It still says dovecot is not in the group shadow even though it is. Any suggestions? -- View this message in context: http://dovecot.2317879.n4.nabble.com/Dovecot-unable-to-access-the-shadow-fi… Sent from the Dovecot mailing list archive at Nabble.com.

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

24 Jan '13

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

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

24 Jan '13

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

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

23 Jan '13

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

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

[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. Kind regards, - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEVAwUBUPgKuF3r2wJMiz2NAQJRbAf/Rb993MR/j6NeLqxqqaqkry6BU2Kw2Sti xVwU9P6hAK/tb4o647PO1015Pd5XbbUpY0itqNzHguqof8+PuT4bGeECT33Y9mKA l0+Soq0Pi9war+ZHKYoQZizNDSb+fQkyGPSi3AsuHDapSpxwc6zj9v/HjxpHkr7+ l1ln8NcFG9gKZ/dB+eIM14GNHOsVKVI/lKfR4b50CFabIX871KIyXP8GEGyl9mUC te6ROCzcNTbRpyksQEjCh/UQ8PVWz8GNKAzreLMqGfdxp9SRkhSKiJYSGL9i8Rn6 CTKBmLy0Gq5MoF+7roAMBLzJe1TC0mxCkeT6s0G/iJB5vCVnYyo9BQ== =K3ko -----END PGP SIGNATURE-----

[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 ?

[Dovecot] dovecot-2.2.beta1: do not removes e-mail with enabled replication
by Евгений Басов 16 Jan '13

16 Jan '13

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. Thus increasing number of letters like with copy. Possible reasons cause of the problem: - bug - configuration settings of dovecot - users with wich dovecot works and users rights.

[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

[Dovecot] Dovecot subtree problem in ldap/ad search
by Marcus Jüttner 15 Jan '13

15 Jan '13

Hallo Im trying to set up an Postfix and Dovecot mailserver with ActiveDirectory interation. Postfix is doing well and even Dovecot does ... but I have one big problem! 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.

Any other hints? If the UIDs are just headers, why don't you simply checksum without them: sed -e '/^Whatever-header:/d' < $file | md5sum grep -Ev '^Whatever-header:' < $file | md5sum Joseph Tam <jtam.home(a)gmail.com>

[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
