[Dovecot] Quota warning generated when crossing on both sides
by Harm van Tilborg 13 Dec '10

13 Dec '10

Hello everyone, I'm experimenting with the quota warning plugin. I have the following setting in Dovecot's general config: plugin { quota_warning = storage=75%% /var/www/contrib/doquotawarning.py 75 quota_warning2 = storage=90%% /var/www/contrib/doquotawarning.py 90 } The doquotawarning.py script is working okay -- meaning that the user gets a warning. My SQL backend uses the following query: user_query = \ SELECT m.maildir AS home, 1001 AS uid, 1001 AS gid, \ CONCAT('*:bytes=', m.quota, 'M') AS quota_rule, \ 'Trash:ignore' AS quota_rule2 \ FROM mailbox m \ INNER JOIN domain d \ ON d.id = m.domainid \ WHERE d.domain = '%d' \ AND m.user = '%n' Where m.quota is the user's personal quota (in MB). As you can see, we ignore the 'Trash' box, when considering the usage data. We are using the dict quota backend. Now this is what happens. Assume we have 'user(a)example.org', that has a quota of 10MB and he currently has 5MB in use. Now someone sends a 3MB email towards 'user(a)example.org'. Dovecot does indeed generate the warning message (75%), that arrives correctly 'together' with the 3MB email. Now the user moves the 3MB email to trash. This goes well, however: Dovecot generates the 75% warning message again. Which is not necessary: the user was cleaning his mailbox, i.e. usage is 5MB again. I have the feeling Dovecot is generating the warning event twice. When getting from e.g. 50% to 79% and when the usage is lowered from 87% to 70%. I have the feeling this is either not the correct behavior, or I'm misinformed. When looking at the source, this shouldn't be happening: if ((bytes_before < (uint64_t)warnings[i].rule.bytes_limit && bytes_current >= (uint64_t)warnings[i].rule.bytes_limit) || (count_before < (uint64_t)warnings[i].rule.count_limit && count_current >= (uint64_t)warnings[i].rule.count_limit)) { quota_warning_execute(root, warnings[i].command); break; } We're using Dovecot 1.2.9 (Ubuntu's 10.04 LTS version). -- Kind regards, Harm van Tilborg

[Dovecot] Crash in 2.0.8 dovecot/imap - information capture
by Tom Talpey 13 Dec '10

13 Dec '10

My dovecot logs revealed a crash in the dovecot/imap process a few days ago. It appears to have dereferenced 0x00000004 in the storage shared lib. Unfortunately, I didn't get a core and I'm not sure how to reproduce it. Dovecot 2.0.8 on linux32. Two questions: 1) How can I be sure I get a core next time? I think it's because I run dovecot/imap under a mail uid and didn't have write permission to the cwd. Any way to verify that was it, and be sure it works? 2) What other settings would provide more info if it happens again? Thanks! dovecot.log excerpt: Dec 10 08:43:53 master: Error: service(imap): child 30862 killed with signal 11 (core dumps disabled) Dec 10 08:43:53 imap-login: Info: Login: user=<xx(a)yy.com>, method=PLAIN, rip=169.254.100.10, lip=169.254.100.100, mpid=2243 kernel dmesg: imap[30862]: segfault at 4 ip b772ecd2 sp bfc90f90 error 4 in libdovecot-storage.so.0.0.0[b76e9000+b8000] [~] # dovecot -n # 2.0.8: /etc/dovecot/dovecot.conf # OS: Linux 2.6.33.2 i686 ext4 (not sure of exact config at time of crash, will capture next)

[Dovecot] director_user_expire
by Cor Bosman 11 Dec '10

11 Dec '10

Would it be ok to set director_user_expire to a very high value? Say 1 day? This would pretty much lock a user into a specific server right? What if I set it to 1 year? :) What happens when the server a user is locked into disappears (i remove it from the pool). Then a day later, I add the server again. Is the user now locked to the new server, or will he revert back to the old server? Cor

[Dovecot] Execute Script on LMTP Deliver?
by Edward Carraro 10 Dec '10

10 Dec '10

Is it possible to have dovecot 2.0.8 using LMTP run a shell script each time it delivers a message to a users mailbox? I see there's an "execute = script /path/to/script" but when i added it to lmtp service in 10-master.conf, it didnt do anything and stopped delivering mail altogether service lmtp { executable = script /usr/local/bin/test.sh u% unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix user = postfix } inet_listener lmtp { port = 24 } } $ ls -lh | grep test -rwxrwxrwx 1 root staff 270 2010-12-09 18:05 test.sh $ cat test.sh #!/bin/sh USER=$1 echo $USER > /tmp/newfile basically when a message arrives, it will execute a shellscript which will notify another service that mail has arrived in their inbox

[Dovecot] Phantom INBOX in 1.2. Is there a stable .deb of 2.0?
by ian+dovecot＠comtek.co.uk 10 Dec '10

10 Dec '10

Hi, We've been running 1.2 Dovecot for a while and are happy with it. In trying to migrate from symlinks to shared folders I see a similar problem to that shown at http://www.mail-archive.com/dovecot@dovecot.org/msg32083.html . For example: . lsub "" "*" * LSUB () "." "Users..INBOX" The advice given in the thread is to upgrade to 2.0. We currently use Debian's 1.2 package and I'm reluctant to move since I can't find a stable 2.0 .deb (http://wiki2.dovecot.org/PrebuiltBinaries only has repository heads of 2.0). Building from source is an option but I'd really prefer to be using a package. Can anybody advise on an appropriate way to go? Like the original poster I am seeing INBOX under the shared namespace when I try to share. I'm also getting an empty /var/mail/virtual/users/Maildir created (maildir:/var/mail/virtual/users/%n/Maildir/). We formerly had an INBOX prefix namespace from a Courier migration too, but it has been deleted (to no avail). Shared folders do work, though. It just requires 'anyone l' in /etc/dovecot/dovecot-acls/.DEFAULT (though I'd really rather not do this!). Thanks for any help, Ian ######## mail_location = maildir:/var/mail/virtual/users/%n/Maildir/ namespace private { separator = . prefix = inbox = yes } namespace shared { separator = . prefix = Users.%%n. location = maildir:/var/mail/virtual/users/%%n/Maildir/:INDEX=~/shared/%%u subscriptions = no list = children } namespace public { separator = . prefix = Shared. location = maildir:/var/mail/virtual/public:INDEX=~/public subscriptions = no } auth default { mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot/dovecot-ldap-master.conf master=yes } userdb passwd { } userdb ldap { args = /etc/dovecot/dovecot-ldap-userdb.conf } userdb ldap { args = /etc/dovecot/dovecot-shared-ldap.conf } } plugin { acl = vfile:/etc/dovecot/dovecot-acls:cache_secs=3 acl_shared_dict = file:/var/mail/virtual/shared-mailboxes.db }

[Dovecot] Released Pigeonhole v0.2.2 for Dovecot v2.0.8
by Stephan Bosch 10 Dec '10

10 Dec '10

Hello Dovecot users, The new Dovecot v2.0.8 release has a few changes that prompted changes in Pigeonhole as well. This means that a new release of Pigeonhole is also necessary, because otherwise things will not compile anymore. Apart from a few rather minor bugfixes, some of which originate in Dovecot, one TODO item has finally been resolved: the reject action uses the LDA mail reject API, meaning that the associated LDA settings now also work for Pigeonhole, as would be expected. Changelog v0.2.2: * LDA Sieve plugin: started using Dovecot LDA reject API for the reject extension. This means that the LDA reject_reason and reject_subject settings now also work for Pigeonhole's LDA Sieve plugin. * Did some work on the new sieve-filter tool. It is mostly functional, but it is not finished yet. * Dovecot change: services' default vsz_limits weren't being enforced correctly in earlier v2.0 releases. Now that they are enforced, you might notice that the default limits are too low and you need to increase them. This problem will show up in logs as "out of memory" errors. See default_vsz_limit and service { vsz_limit } settings. - Imap4flags: fixed segfault bug occurring in multiscript context. - Added version checking to the ManageSieve settings plugin. This plugin was forgotten when the LDA plugin was updated with this change in the previous release. - LDA Sieve plugin: fixed memory leak at deinitialization. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.2.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.2.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Dovecot as IMAP proxy to Exchange
by Hugo Monteiro 09 Dec '10

09 Dec '10

Hello list, I'm looking into the possibility to setup dovecot to act as an IMAP proxy to an Exchange server. Things i know beforehand: - I will not be able to use the ldap (Active Directory) user DN for auth binds (but i discovered that i could could use the user userPrincipalName attribute as bind DN. I tested it using ldapsearch and it worked fine.) - I will not be able to perform any unbinded searches. - The Exchange server is unique, so i can setup a static proxy route to the server. Given the above, i'd like to post some questions: 1 - Will i be able to use auth_bind = yes given the restrictions? My first guess is that this might work if i use something like "auth_bind_userdn = %u(a)example.org" 2 - Will i be able to specify a static route to the exchange server, not having to rely on that information from the AD itself? Another thing i'd like to know is if NTLM auth can be used while dovecot acts only as proxy. Thanks in advance, Hugo Monteiro. -- fct.unl.pt:~# cat .signature Hugo Monteiro Email : hugo.monteiro(a)fct.unl.pt Telefone : +351 212948300 Ext.15307 Web : http://hmonteiro.net Divisão de Informática Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa Quinta da Torre 2829-516 Caparica Portugal Telefone: +351 212948596 Fax: +351 212948548 www.fct.unl.pt apoio(a)fct.unl.pt fct.unl.pt:~# _

[Dovecot] Dovecot 1.2/2.0 coexistence guide?
by Tom Talpey 09 Dec '10

09 Dec '10

I am running Dovecot 1.2.16 and considering moving up to 2.0.8. I have found <http://wiki2.dovecot.org/Upgrading/2.0> but there's not a lot about deploying a 2.0 server alongside an existing 1.2. Any hints on a seamless approach to this, especially one that might allow me to upgrade individual users in place, without moving their maildirs into a new tree and still avoid issues with 1.2/2.0 sharing access?

[Dovecot] How to handle "Waiting for authentication process..."
by A.L.E.C 08 Dec '10

08 Dec '10

Sometimes, when dovecot authentication processes are busy, dovecot write reply "Waiting for authentication process to respond.." to client.

[Dovecot] local seen flags with shared mailboxes
by Tim Mauerbach 08 Dec '10

08 Dec '10

Hello all, after recent upgrade from 2.0.5 to 2.0.8 it seems that local seen flags for mails reside in shared mailboxes doesn´t work anymore. Before the upgrade I had read mails with account #1. Account #2 (who has access via acl) saw the mails still as unread. Now, no matter who read the mails, the other account see the same flags, immediately. I read the related wiki pages again and tried to find any configuration error, unfortunately without much success. I´ve attached output from "doveconf -n" and a debug logfile. Thanks a lot! Tim

As I mentioned in another post, your log message clearly shows the IPv6 address is being used. And yes, your host obviously is capable of that. You don't need to specifically enable it with fetchmail. It will under certain circumstances default to IPv6, which in your case happened. As also mentioned, your postfix seems to not bind to the IPv6 address by default, though, or it has deliberately been disabled. Moreover, your router is not even in the picture here -- just like dovecot, FWIW. Fetchmail fetches the mail from a remote server, and tries to deliver it locally. That local delivery step is generating the log messages. A mail, sent from and to your box. Long after the data stream passed your router...

[Dovecot] imap/pop proxy and filter

[Dovecot] proxy and gpg processing
by Mike 07 Dec '10

07 Dec '10

Hi I have dovecot running as pure proxy for accessing imap and pop mailboxes on other servers. How can I do the following scenario: When a client user reads a gpg signed or gpg encrypted email through the proxy, can I verify/decrypt the email before it gets delivered to the client user? Ideally I would like to write a perl program which processes the email within the proxy before it gets delivered to the user. With Sieve I can not do this, is there another way to achieve this? Thanks for any hint. Mike

[Dovecot] imap limits please ?
by Spyros Tsiolis 06 Dec '10

06 Dec '10

Hello, Finally managed to sync an outlook client to dovecot. Looks like it's working. Questions though ; : What are the limits? Number of Folders ? Number of mails per folder ? E.g. for a client of mine, I know that she uses about 5Gb of data at the moment (and counting). Now, this same outlook client consists of the following : 1. about thirty (30) folders ranging from 1000 messages per folder to 100 messages per folder 2. A "Sent Items" folder with about 4,000 messages (and counting) 3. A "Deleted Items" folder with about 5,500 messages (and counting) System, now, is a CentOS 5.5 32-bit on an hp/compaq dl360 (G3) with RAID1 76,3Gb Disks UW320 and four (4Gb) of RAM Output of "dovecot -n" : ------------------------------------------------------------ # 1.2.16: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.17.4.el5 i686 CentOS release 5.5 (Final) ext3 base_dir: /var/run/dovecot/ log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot-info.log ssl_parameters_regenerate: 48 verbose_ssl: yes login_dir: /var/run/dovecot//login login_executable: /usr/local/dovecot/libexec/dovecot/imap-login login_greeting: * Dovecot ready * login_max_processes_count: 32 mail_location: maildir:/var/MailRoot/domains/%d/%n/Maildir mail_plugins: zlib auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /etc/dovecot/passwd passdb: driver: pam userdb: driver: static args: uid=vmail gid=vmail home=/home/vmail/%u userdb: driver: passwd ------------------------------------------------------------ Any answer would be greatly appreciated since I am trying to know the systems' limits.

[Dovecot] CentOS 5 + selinux
by Marcelo Roccasalva 06 Dec '10

06 Dec '10

I've just installed CentOS 5.5 and dovecot 2.0.7. Out of the box, it worked ok with local user accounts. Then I enable selinux and I could no loger login to imap server. I can deal with that via a local policy. But I found dovecot tried to open /etc/shadow: type=AVC msg=audit(1291490764.101:670): avc: denied { read } for pid=16130 comm="auth" name="shadow" dev=md2 ino=96335 scontext=user_u:system_r:dovecot_t:s0 tcontext=system_u:object_r:shadow_t:s0 tclass=file type=AVC msg=audit(1291500097.318:818): avc: denied { getattr } for pid=17350 comm="auth" path="/etc/shadow" dev=md2 ino=95396 scontext=user_u:system_r:dovecot_t:s0 tcontext=system_u:object_r:shadow_t:s0 tclass=file even it is configured for pam passdb: # dovecot -n # 2.0.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.26.1.el5 x86_64 CentOS release 5.5 (Final) mbox_write_locks = fcntl passdb { driver = pam } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } I straced the process and it efectively tries to open /etc/shadow. I don't want to disable selinux but I'm not happy letting dovecot read my /etc/shadow. Is there a guide to selinux and dovecot? -- Marcelo "¿No será acaso que ésta vida moderna está teniendo más de moderna que de vida?" (Mafalda)

[Dovecot] 1.2.15 - segfault if host field attribute not present in ldap. (proxy)

If more information's needed, let me know. Also, somewhat unrelated, but maybe the wiki needs to be edited since using a template as =proxy_maybe=y works, while in wiki its kinda opposite. I don't know of specifics, but should I try using a recent release ?

[Dovecot] Problem with ACLs

[Dovecot] Internal Error form delivery from LDAP lookup.
by Jorgen Lundman 06 Dec '10

06 Dec '10

Solaris-x86-10u8 Dovecot-1.2.7 Large mail setup, with quite a few MX servers working well. Generally everything is super. But every now and then, we get "bouts of bad weather" - which only lasts a short time, and curiously nearly always occur when mail is sent to customer mailing lists. I suspect mostly because of that 1 message has multiple recipients within the same domain. Perhaps. Delivery setup as: main.cf: virtual_transport = dovecot dovecot_destination_recipient_limit = 1 dovecot_destination_concurrency_limit=300 master.cf: dovecot unix - n n - 70 pipe flags=DRhu user=dovecot:dovecot argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} Errors look something like: example.com Dec 06 08:46:25 deliver(rbc-005(a)example.com): Info: msgid=<A22A602A940A45A49EA2C4CC53D27655(a)UQC.local>: saved mail to INBOX Dec 06 08:46:25 deliver(rbc-002(a)example.com): Info: msgid=<A22A602A940A45A49EA2C4CC53D27655(a)UQC.local>: saved mail to INBOX Dec 06 08:46:28 deliver(rbc-004(a)example.com): Error: userdb lookup(rbc-004(a)example.com) failed: Internal failure Dec 06 08:46:28 deliver(rbc-011(a)example.com): Error: userdb lookup(rbc-011(a)example.com) failed: Internal failure Dec 06 08:46:28 deliver(rbc-013(a)example.com): Error: userdb lookup(rbc-013(a)example.com) failed: Internal failure Dec 06 08:46:28 deliver(rbc-006(a)example.com): Error: userdb lookup(rbc-006(a)example.com) failed: Internal failure Later on, when it retries, everything goes according to plan and delivery is achieved. Now this is actually due to slapd saying: Dec 6 08:46:25 vmx15.unix slapd[3958]: [ID 763815 local4.debug] connection_input: conn=72057 deferring operation: too many executing And since it happens most frequently with mailing-lists, or mails with many recipients, I would guess it is due to a large number of lookups happening in a very short time. Since dovecot_destination_recipient_limit=1, I believe 'deliver' is only ever called with just one recipient for "-d", and 'deliver' probably-does-not (?) query LDAP for any of the other "To:" addresses in the message body. Is that the case? Secondary, the dovecot-ldap.conf for dovecot-auth has: hosts = 127.0.0.1 172.20.12.33 172.20.12.23 172.20.12.113 So even though localhost's slapd was busy at the time, the other three hosts were definitely not. Is LDAP fail-over ... failing... in this case? How many concurrent queries does dovecot-auth perform? Any way to tweak this value? Admittedly, postfix/dovecot does handle this situation correctly, as 'temporary failure' and mail delivery is merely delayed. But at the same time, it *could* be something with an easy fix as well.

What exactly is the error message? Is it always the same specific user, or if you reorder users is it always the 150th?

[Dovecot] Dovecot v2.1 plans
by Timo Sirainen 06 Dec '10

06 Dec '10

Now that v2.0 seems to be getting stable, I finally started v2.1 branch: http://hg.dovecot.org/dovecot-2.1/ So far there are just some API changes to fix some annoyances and to make it simpler. They'll probably keep coming for a while more to make future work easier. As for larger upcoming features, I'm hoping for: - simplify index files and make it write only via lib-fs (but keep backwards compatibility & make v2.0 forwards compatible) - make lib-storage API support asynchronous and support parallel lookups - use async disk io as much as possible & get rid of all lock waits inside lib-storage -> it'll be ok to have lots of imap/pop3 connections per process, at least for some storage backends - write imap-client lib-storage backend (make it fast using above async stuff - using configurable number of IMAP connections) - this could maybe also be used to access other users' shared mailboxes when it can't be done directly - design a mailbox format (maybe based on dbox) for key-value databases, implement it via lib-fs and implement a lib-fs backend for one such database - merge Apple's CATENATE and URLAUTH patch But if some company desperately wants me to work on other stuff, that list can change. BTW. I'm moving back to Finland in two weeks. Maybe I'll also get some studying done towards my Master's degree. :)

With 2.0.8 I get the following message when running the configure script: "configure: WARNING: unrecognized options: --enable-header-install" Is this intentionally? Is there a substitute directive for Sieve when compiling Dovecot 2.08? Rgds Tamsy

[Dovecot] v2.0.8 released
by Timo Sirainen 03 Dec '10

03 Dec '10

http://dovecot.org/releases/2.0/dovecot-2.0.8.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.8.tar.gz.sig There are many small fixes all around, plus some more noticeable changes: * Services' default vsz_limits weren't being enforced correctly in earlier v2.0 releases. Now that they are enforced, you might notice that the default limits are too low and you need to increase them. This problem will show up in logs as "out of memory" errors. See default_vsz_limit and service { vsz_limit } settings. * LMTP: In earlier versions if mail was delivered to user+detail@domain address, LMTP server always attempted to deliver the mail to mailbox named "detail". This was rather unintentional and shouldn't have been the default. lmtp_save_to_detail_mailbox=yes setting now preserves this behavior (default is no). + Added systemd support (configure --with-systemdsystemunitdir). Based on patch by Christophe Fergeau. + Replaced broken mbox-snarf plugin with a new more generic snarf plugin. - dbox: Fixes to handling external mail attachments - verbose_proctitle=yes didn't work for all processes in v2.0.7 - imap, pop3: When service { client_count } was larger than 1, the log messages didn't use the correct prefix. Last logged in user's prefix was always used, regardless of what user's session actually logged it. Now the proper log prefix is always used. - MySQL: Only the first specified host was ever used

[Dovecot] Indexes.
by Henrique Fernandes 03 Dec '10

03 Dec '10

Hello people! I have huge problems with IO wait becase dovecot configured to use maildir is under OCFS2 1.4. Now i have an question to OCFS2 each disk action is really heavy becaue it has no index. Now i am thinking in what can be done to heltp my system to use less disk. Looking for index and etc in dovecot i found this, this disables the index file on disk and leave it on ram or it disable the index files ? If you really want to, you can also disable the index files completely by appending :INDEX=MEMORY I am only trying to get dovecot to work faster. Right now we have to waing some seconds to dovecot list all emails or read an email. I am also thinking in right index to an NFS but i don't know if this makes any diferences in performance. Thanks to all! I use 3 servres wrinting on OCFS2 one is mailman, and other two are to email, I have ipvs to load balance the conections. []'sf.rique

Hello to all, I am setting up a mail server using sendmail and dovecot 2.0.7 with maildir storage. I want to use dovecot lmtp as local mail delivery agent becouse when I send a message to multiple recipients it deliver the message to all recipients with hard links instead of store n copies of the message. The only think I can't set up is make dovecot-lmtp reading the .forward file in the user's home directory. I think I am missing something, becouse dovecot-lda read that file but don't do hard links when deliver the mail. What I am missing?

[Dovecot] SSL issues on separate IPs
by Tim Traver 03 Dec '10

03 Dec '10

Hi Timo, I have set up 2.07 to answer on several different IP's with different SSL certs, like the following : local 209.132.xx.4 { ssl_cert = </shared/templates/res/1040/certs/*.xxxxx.com.crt-pem-298 ssl_key = </shared/templates/res/1040/certs/*.xxxxx.com.key-298 } I have several of these, and there appears to be a problem with one in particular that is dropping connections, and I'm not sure why. In this case it is a wildcard cert issued from godaddy, and I have the cert file in pem format with the chain on it. I have another completely separate local IP setup with a different cert on it that works without any problems. This particular one drops the connection when I try to connect to IMAP using TLS on port 143, or using the IMAP SSL port of 993. When I try it using Thunderbird, I am using the default settings for both tests. The Thunderbird error I get is "The server has disconnected. The server may have gone down or there may be a network problem." I don't see any errors in the dovecot error log or the system error log, and when using doveadm who to view the current connections, it does not show a connection. I tried enabling the logs for SSL errors, but nothing appears for my IP when attempting to connect. FreeBSD 8.1 with openssl 0.9.8n. The IP's are on the box and are on the loopback interface if that makes any difference for a direct server return load balancing system. But, I don't know how that would make a difference since one of the separated IP's works with its cert, and the other one disconnects. Thanks, Tim.

[Dovecot] Static userdb with LDAP passdb but without "allow_all_users=yes"?
by Andreas Ntaflos 03 Dec '10

03 Dec '10

Hi, Is it possible to have a static user database along with an LDAP password database and *not* be forced to set "allow_all_users=yes" for the userdb? The wiki page on static user database says "Normally static userdb handles this by doing a passdb lookup instead." How should the passdb behave in order for this to work? In my tests (on a test server) I am using Dovecot 2.0.7 and Postfix 2.7.0 on Ubuntu 10.04.1. I use (or am trying to use) LMTP with Dovecot and Postfix according to the HOWTO in the wiki [1] as well as dynamic address verification with LMTP [2]. Users are virtual, using a static userdb and passwords from LDAP. I also serve local system users which is why I also have userdb and passdb pam, but this isn't the issue here. Delivering mail to an existing virtual user works fine as far as I can see but when a non-existent user is the recipient Dovecot complains that the passdb doesn't support lookups: postfix/smtpd[26469]: connect from remote-smtp.example.net[10.0.0.10] postfix/cleanup[26474]: 772A760B25: message- id=<20101125172409.772A760B25(a)mailtest.example.com> postfix/qmgr[27672]: 772A760B25: from=<double- bounce(a)mailtest.example.com>, size=276, nrcpt=1 (queue active) dovecot: lmtp(22109): Connect from local dovecot: auth: Error: static(not-a-user(a)test01.example.com): passdb doesn't support lookups, can't verify user's existence dovecot: lmtp(22109): Error: user not-a-user(a)test01.example.com: Auth USER lookup failed dovecot: lmtp(22109): Disconnect from local: Client quit postfix/lmtp[26475]: 772A760B25: to=<not-a-user(a)test01.example.com>, relay=mailtest.example.com[private/dovecot-lmtp], delay=0.18, delays=0.17/0.01/0/0, dsn=4.3.0, status=undeliverable (host mailtest.example.com[private/dovecot-lmtp] said: 451 4.3.0 <not-a- user(a)test01.example.com> Internal error occurred.

To summarise: I want to use LMTP, dynamic address verification, a static user database and an LDAP password database.

The best fix for this is to prevent it from happening. Configure your setup so that a user always gets redirected to the same server (unless it's down). This also means that mail deliveries must be done by the same server, or alternatively it shouldn't update index files. Dovecot flushes NFS caches when needed if you set mail_nfs_storage=yes, but unfortunately this doesn't work 100%, so you can get random errors. Disabling NFS attribute cache helps a lot in getting rid of caching related errors, but this makes the performance MUCH worse and increases the load on NFS server. This can usually be done by giving actimeo=0 or noac mount option. Index files As described above, it's better to redirect users to the same server whenever possible. If you do this, it might also be a good idea to keep index files stored locally in that server. If user gets occasionally redirected to another server, the indexes will then be created locally there. This isn't a problem. However you might want to create a cronjob to delete old index directories. If you choose to keep the index files stored in NFS, you'll need to set mmap_disable=yes. Both the mmap_disable and indexing to NFS will result in a notable performance hit. If you're not running lockd you'll have to set lock_method=dotlock, but this degrades performance. Note that many NFS installations have problems with lockd. If you're beginning to get all kinds of locking related errors, try if the problems go away with dotlocking. ------------- but i agree, there should be more info with cluster file systems in the wiki perhaps Timo has time to send recommands by mail, i am not sure that mine are optimal ( whatever i have no problems yet ) > > > I will try send an image on the load of machine. > > > []'sf.rique > > > On Thu, Dec 2, 2010 at 11:25 AM, Robert Schetterer > <robert(a)schetterer.org <mailto:robert@schetterer.org>> wrote: > > Am 02.12.2010 14:10, schrieb Henrique Fernandes: > > With recomendation settings do you have ? > > http://wiki2.dovecot.org/MailLocation/SharedDisk > > and a few more optimizes about maildir > > > > how many clients ? > > i started the server not long ago so they are less yet ( about 100 > maildirs ) > but i have my own account in it which has massive mails ( 10 GB store > with over 1000 mails daily in out , and perhaps 10000 mails in store) > > > > > sorry, i did not say i use dovecot 2.0.6 > > looks fine, update to 2.0.8 if ready > > > did you use the mail option at ocfs2 store creation ? > > what os/distro do you use , i remember bugs with ocfs with some distro > versions > > > > > []'sf.rique > > > > > > On Thu, Dec 2, 2010 at 10:40 AM, Robert Schetterer > > <robert(a)schetterer.org <mailto:robert@schetterer.org> > <mailto:robert@schetterer.org <mailto:robert@schetterer.org>>> wrote: > > > > Am 02.12.2010 13:13, schrieb Henrique Fernandes: > > > Hello people! > > > > > > I have huge problems with IO wait becase dovecot configured > to use > > maildir > > > is under OCFS2 1.4.

[Dovecot] Virtual folder root cannot be opened, virtual folders ok
by Tom Talpey 02 Dec '10

02 Dec '10

I am running dovecot 1.2.16 and not able to figure out an error that happens whenever I select the root of a virtual mailbox tree. At the moment I have a simple maildir store, accessed via IMAP, and have successfully added a virtual fs namespace with two subdirectories. I have created dovecot-virtual entries in the subdirs and they are working fine; they show the expected messages, etc. My problem is with the top-level virtual directory. If I happen to select it in Thunderbird (Eudora, actually), I receive a popup "The current command did not succeed. The mail server responded:Mailbox doesn't exist: Mobile." It also fails in the same way during search, which interrupts it and makes other client operations fail. I have tried placing a dovecot-virtual rule in the directory, leaving the directory empty, moving it in or out of the maildir tree, tweaking namespace and INDEX/LAYOUT options all with the same result - the subdirs are fine, the virtual root fails. I must be missing something obvious. Clue, please? Thanks!

[Dovecot] Virtual mailboxes and subfolders
by François-Xavier Payet 02 Dec '10

02 Dec '10

Hello again, I'd like to know if there is a way to have subfolders in virtual mailbox? In my virtual namespaces, I have some virtual maiboxes named like this : Mailbox Mailbox.SubMailbox (the separator is '.') But when I try to access the submailbox, depending on my client, it either : - Tells me the mailbox doesn't exists (Roundcube) - Don't show me any error, but don't display any mail in the mailbox (Apple Mail.app) So I'd like to know if this is because I can't make subfolders of virtual mailboxes, or if I'm doing something wrong. Thanks.

[Dovecot] Have inbox at the same place
by Spyros Tsiolis 02 Dec '10

02 Dec '10

Hello again, I have an installation with dovecot and I am accessing it through linux mint and thunderbird v3.0.10 As thunderbird "subscribes" to dovecot, it does the following : Inbox Trash MyName(a)Mydomain.gr Local Folders Local Folders MyName(a)Mydomain.gr subfolder A Subfolder B Subfolder C Subfolder D Subfolder E Local Folders Outbox OK, I have to admit a have a couple of folders more than what I need. But this is fine. My problem is that *everything* is in its respective place (say, *all* subfolders have their respective e-mail properly laid in there), but the messages I keep on the inbox is the "Inbox" folder. What I would like to have is my Inbox messages under (or *on*) MyName(a)Mydomain.gr folder. Also, trash mail goes to : Trash MyName(a)Mydomain.gr folder. Could this also be under the more generic MyName(a)Mydomain.gr folder further down the tree ? (Hope you understand this :-) The tree above is represented exactly as it looks like on thunderbird (with the indentations and everthing). The "dovecot -n" output follows : ------------------------------------------------------------------- # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.17.1.el5PAE i686 CentOS release 5.5 (Final) ext3 base_dir: /var/run/dovecot/ log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot-info.log ssl: required ssl_parameters_regenerate: 48 verbose_ssl: yes login_dir: /var/run/dovecot//login login_executable: /usr/local/dovecot/libexec/dovecot/imap-login login_greeting: * Dovecot ready * login_max_processes_count: 32 mail_location: maildir:/var/MailRoot/domains/%d/%n/Maildir mail_plugins: zlib auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /etc/dovecot/passwd passdb: driver: pam userdb: driver: static args: uid=vmail gid=vmail home=/home/vmail/%u userdb: driver: passwd ------------------------------------------------------------------- Is this possible ?

Greetings yesterday i was resetting an account from a script. and the user was deleted an re-added. subsequently the user now has two dovecot directories.

[Dovecot] Permission denied error log messages
by Tim Traver 02 Dec '10

02 Dec '10

Hi Timo, ok, I have a large 2.07 NFS setup, and I have been monitoring error messages to make sure I catch things, and I've come across a lot of messages that come in pairs and look like this : Dec 01 17:48:35 lda(paul(a)xxxxxx.com): Error: write(/home/mailboxes/data/301/paul@xxxxxx.com/Maildir/tmp/1291254514.M620308P83269.mta2.scaledsystems.com) failed: Permission denied Dec 01 17:48:35 lda(paul(a)xxxxxx.com): Error: sieve: msgid=unspecified: failed to store into mailbox 'INBOX': Internal error occurred. Refer to server log for more information. [2010-12-01 17:48:34] I run the dovecot installation as a single user, and that user owns ALL of my virtual accounts directories. I checked, and there aren't any permissions that aren't correct. All the way up the tree has the same owner and group, and there are plenty of messages that make it through without any issue. The NFS servers don't have enough load on them to return errors for file operations, so I don't believe it is that. We use high end NetApp equipment and have never had any problems with them. I'm baffled as to why it gets permission denied message on the tmp directory. There does not seem to be a recognizable pattern for times, or particular accounts. I've just got a heck of a lot of these messages in the deliver log error files... I use qmail control files to feed the lda delivery for messages. When these errors happen, is the message lost? or is it still queued up in qmail's queue when the lda gives a fatal error like that? Thanks, Tim. here is my dovecot -n output : # 2.0.7: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.0-RELEASE-p3 i386 auth_username_format = %Lu auth_username_translation = %@ auth_verbose = yes disable_plaintext_auth = no dotlock_use_excl = yes first_valid_uid = 100 listen = * lock_method = dotlock log_path = /local/logs/dovecot.errors mail_fsync = always mail_gid = 100 mail_location = maildir:%h/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " quota" mail_uid = 100 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 imapflags notify mmap_disable = yes passdb { args = /bin/checkpassword_dovecot_auth driver = checkpassword } plugin { quota = maildir:User quota quota_rule = Trash:storage=+100M sieve = ~/.dovecot.sieve sieve_after = /home/mailboxes/sieve/to_spam_folder.sieve sieve_dir = ~/Maildir/sieve sieve_extensions = +notify +imapflags } protocols = imap pop3 sieve service auth { unix_listener auth-userdb { group = sn mode = 0600 user = sn } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /bin/checkpassword_dovecot_deliver driver = checkpassword } verbose_proctitle = yes protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { info_log_path = /local/logs/dovecot-deliver.log log_path = /local/logs/dovecot-deliver-errors.log mail_plugins = " quota sieve" } protocol imap { mail_plugins = " quota imap_quota" } protocol sieve { managesieve_sieve_capability = comparator-i;ascii-numeric fileinto reject vacation imap4flags notify include envelope body relational regex subaddress copy }

Hi, I'm sorry if this is a silly question, but i know that is not possible in Courier, so, I need to check if I can do it with Dovecot. Can I use PAM authentication, witch get the users data from a external database (like mysql)? I've found many ways to do this stuff disconnectedly (like pam authentication with passwd ), but i can put all together? I can't use the passwd... Thank's, Álvaro

[Dovecot] How to know if dovecot director is running OK?
by Antonio Perez-Aranda 30 Nov '10

30 Nov '10

I'm using director on dovecot 2.0 At present, I know that two instances are connected, If I stop of one system, then I can watch how to the connections are closed on port 5000. I defined 5000 as director port. I have one user (user1) connected to kvm1 (192.168.13.100) and kvm2 (192.168.13.101) servers vía telnet telnet kvm1 143 and then login telnet kvm2 143 and then login If try to execute doveadm director status I can watch the two server like that: [root@kvm1 ~]# doveadm director status mail server ip vhosts users 192.168.13.100 100 0 192.168.13.101 100 0 If I try to find if a server has been asigned to user, but I don't know if it is running correctly [root@kvm1 ~]# doveadm director status user1 Current: not assigned Hashed: 192.168.13.101 Initial config: 192.168.13.101 [root@kvm2 ~]# doveadm director status user1 Current: not assigned Hashed: 192.168.13.101 Initial config: 192.168.13.101 Is there any way to test if it really running?

[Dovecot] "doveadm auth user" requiring a tty
by Axel Luttgens 30 Nov '10

30 Nov '10

Hello, "doveadm auth user password" may be scripted without a glitch. But this comes with the usual problem of a "ps" command showing the password, which may be especially annoying in case of a single-letter typo: the almost correct password is then visible for about two seconds... Clearing the password argument (zeroing it) in doveadm-auth.c, in the hope to reduce the window during which the password may be catched, didn't prove successful. "doveadm auth user" could be an alternative, but it imperatively requires a tty, which may not always easily nor efficiently be available in a scripting environment. I thus ended with this very quick and dirty hack (I guess this should be named that way): --- askpass.original.c 2010-05-31 18:36:52.000000000 +0200 +++ askpass.c 2010-11-27 19:12:03.000000000 +0100 @@ -16,8 +16,24 @@ char ch; int fd; + // A very crude attempt... this supposes that STDIN not being a tty + // may never happen outside of "doveadm auth", and that STDIN will + // always be clean. + //if (!isatty(STDIN_FILENO)) + // i_fatal("stdin isn't a TTY"); if (!isatty(STDIN_FILENO)) - i_fatal("stdin isn't a TTY"); + { + pos = 0; + while (read(STDIN_FILENO, &ch, 1) > 0) { + if (pos >= buf_size-1) + break; + if (ch == '\n' || ch == '\r') + break; + buf[pos++] = ch; + } + buf[pos] = '\0'; + return; + } fputs(prompt, stderr); fflush(stderr); but this for sure must overlook a lot of things. What would be the best way to achieve a scriptable "doveadm auth", say through php's proc_open(), without possibly compromise passwords? TIA, Axel

[Dovecot] Plan: ACL changes
by Timo Sirainen 30 Nov '10

30 Nov '10

Global ACLs are intended to apply to a few mailboxes for all users. For example you could have a master user called "spam" that would have access to each user's "spam" mailbox, but nothing else. Global ACLs are kind of ugly. A mailbox's ACL is found from exactly the same name as what the mailbox's virtual name is. So for example if you have namespace { separator = / prefix = foo/ } And you have a mailbox called foo/bar, the global ACL is looked up from the <global dir>/foo/bar. The problem there of course is what if you want to set global ACLs for "foo". You can't have both directory and a file called "foo". So if this happens, Dovecot instead looks up the ACLs from <global dir>/foo/.DEFAULT file. The name for this file is slightly confusing, and also of course if there really is a mailbox called ".DEFAULT" it won't really work well. Global acl is currently configured by giving its path to acl setting, such as: plugin { acl = vfile:/etc/dovecot/global-acls } So plan #1: deprecate this usage. If global-acls is a directory, keep using the old method. But the new preferred method would be for it to be a file that contains all of the global ACLs. Typically there should be very few entries, so this should also be more efficient. Also this would allow setting default ACLs for namespaces by using wildcards. For example you could have: * masteruser +lrw spam spamuser +lr test/* testuser +lr etc. The * would match only within a single namespace, so if you had more than one, the * entry would match only the one having prefix="". The * entry would be especially helpful for master users who you intend to have access to user's all mailboxes. Currently there is no good way to implement this. Plan #2: Add support for per-user default namespace ACLs. In the mail root directory if "dovecot-default-acl" file exists, it's used as the default ACLs. I'm not entirely sure what should happen if it conflicts with the global ACLs. Probably they both should be simply merged, since both can only be created by an admin. Probably the per-user ACL should be allowed to override the global ACLs. Any thoughts? Since neither of these would break backwards compatibility, I could add them to v2.0.x.

[Dovecot] (vaguely) related to: "doveadm auth user" ...
by Clemens Schrimpe 30 Nov '10

30 Nov '10

While digging through the code I remember having seen something like an (yet undocumented) "update_query" for SQL (and I guess something similar for the LDAP faction as well)?! Can that be used to augment the "doveadm pw" function to actually /set/ the password for a given user instead of just "calculating" the hash, so that an operator can copy&waste it into the respective passdb? Just curious ... I guess it would be nice to have "doveadm" become as central point of administration (yeah, yeah - we would still need a "create user" and "delete user", etc. -- but we would at least be further on our way, wouldn't we? :-) Just 2¢ from Clemens

[Dovecot] SQL insert?
by Oliver Berse 29 Nov '10

29 Nov '10

Hi, I want to log some informations about a mail in a mysql database when the mail is saved to inbox (for a groupware). I use Dovecot 1.2.16 and the log message "msgid=<xxx>: saved mail to inbox" is generated in deliver.c. I find all the needed data in that file. But I'am not sure how to use the functions in sql-api.h or sql-api-private.h to send a simple SQL insert statement to the database. Can anyone give me a hint how to do this? best regards, Oliver

[Dovecot] Dovecot and loading OpenSSL libraries
by Paul Griffith 29 Nov '10

29 Nov '10

Hi, I am running into a interesting issue with Dovecot. I compiled Dovecot 2.0.7 with LD_RUN_PATH set to /xsys/lib and it was able to find and link against the correct OpenSSL libraries (/xsys/lib), the generated Makefile look OK. Here is a snippet of the SSL cflags and libs. SSL_CFLAGS = -I/xsys/include SSL_LIBS = -L/xsys/lib -lssl -lcrypto -ldl After I compil, install and run Dovecot I get the following error. ssl-params: Error: dovecot/ssl-params: error while loading shared libraries: libssl.so.0.9.8: cannot open shared object file: No such file or directory It seems that Dovecot can't find the SSL libraries, even if I set the LD_LIBRARY_PATH environment variable. I always assume that the Dynamic Loaded (dl) library would pickup LD_LIBRARY_PATH. If I add /xsys/lib to /etc/ld.so.conf and regenerate my /etc/ld.so.cache file, Dovecot works without any error messages. Any ideas why SSL_CFLAGS, SSL_LIBS and LD_LIBRARY_PATH aren't been honored ? 78 % /xsys/pkg/dovecot/bin/doveconf -n # 2.0.7: /xconf/dovecot/dovecot.conf # OS: Linux 2.6.9-89.0.29.EL.CSE.smp i686 CentOS release 4.6 (Final) ext3 auth_mechanisms = plain login auth_username_format = %Lu doveadm_socket_path = /var/run/dovecot/doveadm-server imap_client_workarounds = tb-extra-mailbox-sep mail_location = mbox:/local/home/%u:INBOX=/local/home/%u/inbox mail_plugin_dir = /xsys/pkg/dovecot/lib/dovecot passdb { driver = pam } pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xv%08Xu protocols = imap pop3 ssl_cert = </xconf/openssl/certs/imapd.pem ssl_key = </xconf/openssl/certs/imapd.pem userdb { driver = passwd } Thanks Paul

[Dovecot] maildir-dbox hybrid
by Roland Stuehmer 28 Nov '10

28 Nov '10

Hi! How can I convert old mailboxes in "maildir-dbox hybrid" to a current dbox? I have a Dovecot installation that was upgraded from 1.2.x to 2.0.x. Having used the old convert plugin during the 1.2-times I am now stuck with mailboxes which are partially converted (maildir-dbox hybrid state). On <http://wiki2.dovecot.org/Upgrading/2.0> it just says to contact the mailinglist. :) | If you have any Maildir files in your dbox, you need to convert them | somehow (contact Dovecot mailing list) Regards, Roland. P.S.: I am currently using version: 2.0.5 (b8803a1e2dc2)

[Dovecot] dovecot genesis v2.0.X
by Jim Pazarena 28 Nov '10

28 Nov '10

V2 of dovecot has had the following releases (to recap) 2.0.0 2010-08-16 2.0.1 2010-08-24 2.0.2 2010-09-08 2.0.3 2010-09-17 2.0.4 2010-09-26 2.0.5 2010-10-01 I am on FreeBSD, and the port committers want to wait till dovecot V2 "stabilizes" prior to adding it to the FreeBSD ports base. So, my question is, respectfully, is dovecot V2.0.5 stable enough for prime-time on a busy ISP mail server? I'll install it myself independent of the FreeBSD ports tree if so. Thanks,

[Dovecot] Mailbox Delete

Hi Timo.... I Modify the plugin autocreate, that create and subscribe a mailbox to user. My modification consist in do the inverse, if my user don't have permission to create and subscribe a folder, the plugin remove and unsubscribe. My function is called in the same place that create and subscribe is called, just seeing if my flag is "create or delete". My function i copy from doveadm + autocreate create mailbox. The delete is made, and works, but i got some errors before the delete.

My question is this: can I create a user "jsmith" to get all emails with the recipient address: dovecotdemo@domain? Because of using LDAP, I need to do a lookup to know that the user "jsmith" is getting emails for "dovecotdemo@domain", NOT "dovecotdemo" (there will be no such user). In postfix's master.cf, I can use LDA to deliver to DoveCot, which needs to know the user name where the message should be delivered to. But I would not know that at the time because I need to do a lookup in LDAP. Does the DoveCot delivery agent have any way to allow me return a different user name after LDAP lookup? I would not want to modify a couple of files to accomplish that, because I would have to do that for every email address created.

[Dovecot] (summarized) wishlist :-)
by Clemens Schrimpe 26 Nov '10

26 Nov '10

Hello All (and Timo in particular :-) -- While reading through some of the conversations on this list over the past two weeks or so, I always thought "how would <this> particular problem affect you and how would you address it in your environment?". This results in a few suggestions, or "thing to wish for", which I thought others may find useful, hence I'm posting this here. 1) the whole "post login scripting" is a mighty tool, yet it presently lacks a few more words in the documentation, i.e., the syntax of the corresponding config files isn't /entirely/ clear to me. Yes, I can replay the examples given, but I'm not fully sure, what happens when, etc. I'm perfectly willing, though, to contribute to that, by documenting findings in the Wiki2 (I'm just using 2.0.x, sorry). I'd appreciate a few more examples, so if anyone has a funny, working configuration, making good use of "post login scripting", I'd appreciate it, if you'd "show" them! :-) Anyway: A bit more "control" over PLS would be nice. For example, I'd like to have a script invoked every time a new "session" starts (new IMAP/POP3 connection from a unique ID), as many clients open multiple connections at once and usually I wouldn't want to see the second, third, nth connection - just the first. "Nice" would also a "post logout scripting" feature - again: Both for "all" connections, as well as just for the "last" one. Yes, this certainly requires a bit more discussion, I know - but I hope to trigger just that with this message! :-) 2) The "local x.x.x.x {" feature is very nice, yet it could use some "polishing", I guess. Inclusion of ports and wildcards for either addresses or ports, for instance. I'm imagining a syntax like this: local 1.2.3.4 { ... } like now to remain backward compatible local 1.2.3.4:* { ... } same result, just different new syntax -> don't care about port local 1.2.3.4:4711 { ... } add port restriction local *:4711 { ... } don't care for address, but match on port and -of course- (yes, I am really USING IPv6), the use of "[2001:xxxx:yyyy::zzzz]" instead of "1.2.3.4" in the examples show above. If one would like to become really funky, the optional "/xx" addition to specify a prefix-length would leave no more wishes open. (Well ... maybe the use of "names" derived from DNS instead of literal addresses, of course :-) [if this feature becomes clearer to me, I'd -again- be happy to help document it within the Wiki2] 3) The "iterate_query" in the SQL interface (I assume, there is something similar in the LDAP realm?) could be supplied with a few (optional, of course) "%x" variables, i.e., "%s" could deliver the "service" again, like with the other queries. This could tell the database engine, what the "show me all users" query is being used for ("quota", "expunge", ... basically all functions of doveadm, where you can supply a "-A" parameter). A "%{env:HOST}" could be used to tell the DB interface, which node of a multi-node installation is "asking". I.e., if you have your users distributed over multiple nodes, each one might want to perform "cleanups" only for their own users, saving a lot of bandwidth for unnecessary NFS traffic, etc. That's it - for now. Otherwise I'm pretty happy with dovecot, let me make that very clear here! :-) :-) :-) Clemens

[Dovecot] ioloop.c panic
by Brad Davidson 26 Nov '10

26 Nov '10

Timo, Just this morning I upgraded from 2.0.6 to 2.0.7 (hg changeset 66a523135836). A few hours later we had some power problems that caused the networking to drop out at one site. The directors on the surviving site all had a few imap-login processes crash with the following error: Nov 23 09:15:30 cc-director1 dovecot: imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) Nov 23 09:15:31 cc-director1 dovecot: imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) Nov 23 09:55:48 cc-director1 dovecot: imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) Nov 23 09:55:51 cc-director2 dovecot: imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) I don't have core dumps enabled, so I can't provide any more information than that. I could enable cores, but I honestly would be hard-pressed to replicate the network cut-out anyway so I'm not optimistic that any cores for this message would ever be forthcoming.

[Dovecot] ldap passdb + mdbox
by Daniel L. Miller 26 Nov '10

26 Nov '10

I previously had a static userdb and an ldap passdb. Everything's been working fine, both 1.2 and 2.0 - but now I need to support the nightly mdbox purge operation. I added the iterate params to my ldap configuration, but (I'm guessing) that with a defined static userdb it won't work. How should I setup my ldap userdb? Do I use prefetch? Current config: passdb { driver = ldap args = /usr/local/etc/dovecot/dovecot-ldap.conf } userdb { driver = static args = uid=vmail gid=mail home=/var/mail/%d/%n mail=mdbox:/var/mail/%d/%n/mdbox allow_all_users=yes } dovecot-ldap.conf: ## dn credentials shouldn't be needed since using auth-bind - but here anyway dn = xxx,dc=amfeslan,dc=local dnpass = xxx ## auth_bind = yes auth_bind_userdn = uid=%n,ou=users,dc=amfeslan,dc=local ldap_version = 3 base = ou=Users, dc=amfeslan, dc=local user_attrs = dbox:%d/%n/Maildir=mail,%d/%n=home user_filter = (mail=%u) pass_attrs = mail=user,userPassword=password pass_filter = (&(objectClass=inetOrgPerson)(mail=%u)) iterate_attrs = mail=user iterate_filter = (&(objectClass=inetOrgPerson)(mail=*)) -- Daniel

[Dovecot] proxy (director) and destination ports
by Oliver Eales 26 Nov '10

26 Nov '10

Hello, i am delivering Mail from postfix via LMTP to dovecot. I am using the director also for LMTP. As long as i connect to the dovecot LMTP TCP socket from postfix everything is working. postfix main.cf: virtual_transport= lmtp:localhost:30025 But when i try to switch to the local socket postfix main.cf: virtual_transport = lmtp:unix:private/dovecot-lmtp The dovecot proxy tries to connect to the backend server port 0 which is obviously not working. The proxy always seems to connect to the same port on the backend as it was accessed itself. Nov 24 14:55:09 auth: Debug: master out: PASS 1 user=1000000000030 proxy Nov 24 14:55:09 lmtp(7330): Debug: auth input: user=1000000000030 proxy host=10.1.1.151 proxy_refresh=450 Nov 24 14:55:09 lmtp(7330): Error: lmtp client: connect(10.1.1.151, 0) failed: Connection refused Nov 24 14:55:11 director: Error: director(15.189.34.59:13459/out): connect() failed: Connection refused Is it possible to set the destination port (30025) of the backend server to the proxy ?

[Dovecot] Director and deliver
by Thomas Hummel 26 Nov '10

26 Nov '10

Hello Timo, Although I haven't tried neither director nor deliver, I'm planning to try both. I've been catching up with threads on this list talking about director but I'm not sure about how deliver would fit into a setup using director. Since deliver would touch indexes and dovecot-uidlist, wouldn't it need to be proxied as well through director ? Is that the case ? If not, how can we use deliver as LDA in a setup where n directors would proxy to m dovecot backends ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] maildir maintenance?
by Brian Kroth 26 Nov '10

26 Nov '10

Hi, I'm running version 1.2.15 (so no doveadm) with around 6000 maildir users, some of which are very large. For completeness, the details of the setup are as follows: - The maildirs are stored via NFS. - The indexes are on a volume local to the dovecot server. - Only one IMAP server currently. - A separate sendmail/procmail server delivers via NFS. I recently wrote the attached script (could probably be improved) meant in theory to be run as a nightly cron job to do the follow: 1) Remove old messages marked as deleted. (I didn't really like the expunge/trash plugins the last time I looked at them.) 2) Rebuild the indexes to account of those changes. (So that the users aren't delayed by dovecot rebuilding them.) 3) Rebuild FTS indexes. (Again to avoid delay.) 4) Rebuild the maildirsize file. (It seems to become slightly inaccurate over time.) To the devs, I'm wondering if this seems sane? To other users of dovecot, I'm wondering what, if any sort of maintenance operations you tend to do in your setups? Thanks, Brian

[Dovecot] Quota by max file size
by Antonio Perez-Aranda 26 Nov '10

26 Nov '10

Is It possible have a quota for max file size? Per example, If the client try to save a very big mail as draft, p.e. 100M, and the limit of Exim configuration is 20M, the mail is really saved in Maildir at sent or Draft but it can't be sent. I think maybe is easy to create a plugin, get the saved stream size and then if it is over quota max file size, abort save and notice to use about the limit, but at first I want to know that really daesn't similar exists.

[Dovecot] iPhone leaves imap process active
by Jim 26 Nov '10

26 Nov '10

A quick search of the archives didn't reveal a fix, so I thought I'd ask the list. I was running Dovecot 2.0.2, and noticed a lot of CPU being used up. I discovered a number of IMAP processes burning a lot of cycles, when no connections should have been active. I traced this to the iPhone leaving the IMAP connection apparently active. I just upgraded to Dovecot 2.0.7, and I'm still seeing connections left active, but haven't seen the high CPU usage yet, but I've only been running 2.0.7 for about 30 minutes. I tried adding kill_idle to the IMAP config, but that doesn't seem to have helped. Turning off the iPhone does kill the connection, so I know that the iPhone is really keeping the connection alive, but if I can find a way to keep these connections down, I'd really rather have that ability. Here's my config: wrights-Mac-mini:/Users/transmit wright$ doveconf -n # 2.0.7: /usr/local/etc/dovecot/dovecot.conf # OS: Darwin 10.4.0 i386 hfs auth_mechanisms = plain login cram-md5 default_internal_user = _dovecot disable_plaintext_auth = no first_valid_gid = 27 first_valid_uid = 27 last_valid_gid = 27 last_valid_uid = 27 mail_gid = 27 mail_location = maildir:/var/mail/vhosts/%d/%n mail_privileged_group = postfix mail_uid = 27 namespace { inbox = yes location = prefix = type = private } passdb { args = /usr/local/etc/dovecot-mysql.conf driver = sql } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service imap-login { process_limit = 64 } service imap { idle_kill = 150 secs process_limit = 128 } service pop3-login { process_limit = 64 } service pop3 { process_limit = 128 } ssl = no userdb { args = /usr/local/etc/dovecot-mysql.conf driver = sql } protocol lda { postmaster_address = postmaster(a)example.com } wrights-Mac-mini:/Users/transmit wright$

[Dovecot] auth_username_chars - special chars
by Hajo Locke 25 Nov '10

Hello, i use dovecot 1.2.11 with auth by mysql. auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@üÜöÖäÄ for some reasons more special chars in username are needed. in fact the % char is meant. Is this recommend to use with mysql? should i expect some problems when using chars with special function within mysql? Config is now: auth default { mechanisms = plain login passdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb prefetch { } } password_query = SELECT `inbox` as `user`, `password`, `home` as userdb_home, `uid` AS userdb_uid, `gid` AS userdb_gid FROM `mail_users` WHERE `login` = '%u' AND `active`='Y' Thanks for your ideas, Hajo

[Dovecot] dovecot transport with postfix and recipient restrictions.
by Mauro 25 Nov '10

25 Nov '10

I'm using dovecot deliver with my postfix smtp. In postfix configuration I have: smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/maps/recipient_checks and in recipient_checks I have: mail(a)example.com REJECT. It doesn't work. Perhaps the recipient restriction has to be put in dovecot side? How can I do this.

[Dovecot] Automatic expire on post-login

25 Nov '10

I need to clear two folder from Maildir at login. Exatly, delete all mails older than 30 days on Trash and 1 day on spam folder. I'm using dovecot 2.0 and I think about use a post-login script calling doveadm -u $user expunge but post-login scripts in dovecot 2.0 are very complex Is there possible to get the environment vars like on dovecot 1.2 ? I think this action must be done by expire plugin, but it isn't the work method if as I understand after read wiki2.dovecot.org about expire plugin, It run only with a cronjob.

Running "doveadm purge" with both -D and -v parms, and both -A and -u options, I don't see much in the way of output. doveadm -v purge -u username just returns with no output doveadm -v purge -A returns no output for most users - for my own mailbox it yields "20 / 21" -D returns the same, along with messages about skipping plugin modules. Is this normal? I'm thinking not - since after deleting messages in the client, emptying the trash, compacting from the client, and then performing a purge - I see no difference in mailbox files. -- Daniel

[Dovecot] two mailboxes - sieve?
by Egbert Jan van den Bussche 24 Nov '10

24 Nov '10

Hi helpful list! I have this user that has two different accounts om the mail server. One is a system account, the other is a virtual account (for what it is worth...). This user would like to have all his email to the virtual mail box (maildir format) automatically moved (or delivered) to the system mailbox (also maildir fornat). Both are on the same machine and use the same postfix/dovecot installation. Something tells me that I might need the sieve plugin for lda here since dovecot is the local delivery transport. I have no knowledge whatsoever about sieve or its scripting. What do I need to o apart from enabling the sieve plugin in dovecot.conf? Or is there another simple solution for this problem directly in Postfix or with fetchmail? A simple working example would be wonderful! TIA Egbert Jan (NL)
