[Dovecot] Is there a hook for a plugin to do some transient operation on the mail body ...
by Jay 23 Nov '12

23 Nov '12

... when the MUA has issued a FETCH? I am a Dovecot newbie ... so please bear with me if this is obvious. Basically what I am trying to do is process the mail body (in my own specific way) before Dovecot serves it up to the MUA. I want to do it as a transient operation in memory. So think of the scenario as ... - the MUA issues a FETCH - Dovecot intercepts the FETCH - Dovecot internally gets the mail from the storage into a buffer in memory ----> This is where I'd like to apply a function to the mail body and modify the mail body in the buffer (not in the storage) - Dovecot serves up the (modified) mail to the MUA Looking for a hook that allows me to do it using a plugin. Looks like the zlib plugin does something similar ... applies a decompression function ... but I am not 100% sure. Thanks for your help. -- J.

[Dovecot] maildir and end-of-line encoding
by Christoph Anton Mitterer 23 Nov '12

23 Nov '12

Hi. I just wondered, the following: My MDA may get mails that use LF or CR/LF end of line encodings and deliver them into maildirs. I couldn't find any information about, whether one should or must convert all into one format, cause AFAIK at least on the IMAP side, CR/LF is always used? How does this work on the maildir/backend side of dovcot? Can it work with both and simply automatically convert LF into CR/LF? Thanks, Chris.

Thank you. One thing that still doesn't work is subscribing to all mailboxes via "*", I guess because the folder names start with "." but dovecot mailbbox subscribe wants it without a starting "." Any clues how that can be solved? Regards Andre

Hi, Is there any code around that lets Dovecot (2.x) aauthenticate via a XMLRPC server (which connects to a LDAP server) instead of going directly to a LDAP server? It could give much more flexibility. TIA Egbert Jan, NL

[Dovecot] v2.1 memory usage
by Timo Sirainen 21 Nov '12

21 Nov '12

v2.1's imap/pop3 processes are linked with OpenSSL by default, because of imapc/pop3c storages. I wonder if you notice any actual (system-global) memory usage reduction when compiling without those and you have thousands of imap processes? ./configure --with-storages=mdbox sdbox maildir mbox cydir I guess I could try it myself also but maybe someone else wanting to reduce memory usage is quicker? :) Related to that, you can look at where imap processes' memory goes with: http://dovecot.org/tools/linux-maps-parse-imap.pl I don't know how much memory those (writable!) file-backed memory areas actually use per-process. Maybe nothing, maybe something..

[Dovecot] users mail folders have to be subscribed
by Andre Bischof 20 Nov '12

20 Nov '12

Hi, I did a migration from cyrus 2.2 to dovecot (fresh installation, details below) via cyrus2dovecot from FU Berlin. That worked, but I first was missing mails in subfolders ander Inbox. No I detected that they are in the users Maildir in folders in his directory. They are listed when using telnet: * LIST (\HasChildren) "." "INBOX.ebay" * LIST (\HasNoChildren) "." "INBOX.ebay.xj" But they are not shown in thunderbird, I have to subscribe to them one by one. I probably did something wrong and maybe messed up with namespace and seperator settings - it would be great if one could lead me out of that. The wiki was a great help installing and configuring everything, but now I'm stuck. I use dovecot 2.1.7 under Ubuntu 12.10: # dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-18-generic x86_64 Ubuntu 12.10 auth_verbose = yes mail_debug = yes mail_location = maildir:~/Maildir managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation s ubaddress comparator-i;ascii-numeric relational regex imap4flags copy include variab les body enotify environment mailbox date ihave namespace inbox { inbox = yes list = yes location = prefix = separator = . type = private } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster@localhost protocols = imap pop3 sieve service auth { unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { deliver_log_format = msgid=%m: %$ mail_plugins = sieve sieve postmaster_address = postmaster quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r } Any help is greatly appreciated!

[Dovecot] upgrade 1.0.15 -> 2.1.7: MBOX index compatibility and performance
by Benoit Branciard 19 Nov '12

19 Nov '12

Hi, we just upgraded our mailserver from Dovecot 1.0.15 to Dovecot 2.1.7. We use MBOX format (due to legacy compatibility), system users, PAM+GSSAPI auth, filesystem quotas, and indexes located on a separate filesystem: mail_location = mbox:~/mail:INBOX=~/mail/INBOX:INDEX=/var/cache/dovecot/indexes/%16Hu/%u The 2.1.7 configuration files have been rewritten based on default templates instead of converting it from 1.0.15. The server has ~8000 mailboxes and about ~2000 simultaneous IMAP/POP active connexions. The problem is: - indexes seem to be rebuilt: first IMAP/POP connexion for each user thows lots of error messages in the log, and the global index size decreases. Example error log: Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: copy: i_stream_read() failed: Input/output error Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 - load average is extremely high (more than 10x the usual one), resulting from an significant increase of disk I/O, and for now (4h after the "monday rush") this doesn't seem to decrease. Questions: - are 1.05 indexes supposed to be backward compatible with Dovecot 2.1.7 ? - are there some technical reasons which could explain the increase of disk I/O, apart from index rebuild ? -- Benoit BRANCIARD Service InfraStructures (SIS) - Direction du Système d'Information (DSI) Université Paris 1 Panthéon-Sorbonne Centre Pierre Mendès France B 406 - 90, rue de Tolbiac - 75634 Paris cedex 13 - France Tél : +33 1 44 07 89 68 - Fax : +33 1 44 07 89 66 Accueil tél. : +33 1 44 07 89 65 Assistance : assistance-dsi(a)univ-paris1.fr Web : http://dsi.univ-paris1.fr -- Ce message a ete verifie par MailScanner pour des virus ou des polluriels et rien de suspect n'a ete trouve.

[Dovecot] advices for a new installation
by Surviet Amine 18 Nov '12

18 Nov '12

hello everyone, first of all, please forgive my bad english skill, I live in France. On our "old" Dovecot 1.x architecture, we have NFS shares between the front servers (MTA, IMAP...) and mail storage server. I've read some wiki2 pages that present the new director and imap proxy. But I'm still don't see things clearly, so I post here to have your advices to set-up a new mail architecture. The hardware we have : - 24x hard drives in a SAS bay - this bay is directly attached via SAS to a server that I'll call : mail storage server - 2 others servers run ProxMox Virtual Environment The PVE will help us to get many virtual servers : - MX : "mail in" servers - IMAP/POP : our hosted clients services These clients may come from webmail (RoundCube) and others clients (Outlook, Thunderbird, mobile clients...) - RoundCube webmail - MySQL server (hosts in databases accounts and settings for Postfix, Dovecot and RoundCube) - maybe antivirus and antispam servers I've read several threads about NFS and IMAP issues. So I decided to not keeping it. In this scenario, I've tried for the mail receiving part : - front-end (postfix lmtp-client) to mail storage server (lmtp server) that seems to runs fine, now i'll must try to add antispam and antivirus scans Now, for the IMAP part, could you, please tell me, if it is better to : - have several IMAP frontend servers that proxy to the mail storage server or - still keeps NFS between the mail storage server and the frontends Dovecot ? On our Dovecot 1.x webmail use imapproxy. I've read that others proxies exist. We have used for a limited time Perdition. What is the differences between imapproxy, Perdition, nginx imap proxy and Dovecot proxy ? Thanks for sharing your experience of "large mail service" that are solid enought to be scaled.

by Tim Smith 18 Nov '12

18 Nov '12

Just wondered if there was a way of making the PLAIN an authentication method for POP3S transactions only without making this an option for IMAP? I am attempting to connect to a POP3S server through the GMail interface available through "Accounts and Import". The issue is that there does not seem to be an option to specify the type of mechanism within their interface so I think I have to offer PLAIN along with SSL. Has anyone else had any experience of using the GMail import settings? -- Tim Smith Tel: 01423 564 078 Mob: 07984 398 299 Email: info(a)titan21.co.uk Web: www.titan21.co.uk

[Dovecot] couple questions about dovecot
by Raan Young 18 Nov '12

18 Nov '12

I am attempting to migrate an ancient IMAP server to Dovecot 2.0.9 running on CentOS 6.3, while trying to minimize the impact on users. Most are using Outlook. I have everything working, but have run into a couple of problems, neither horrible, but both weird. It started when I noticed Outlook shows the .subscriptions file in the folder listing. I figured out a way to prevent that (see below), but then decided to attempt the same tactic to move the .imap index structure out of the folder tree and ran into an interesting side-effect. The .subscriptions issue would seem to be a bug, since the documentation I found implies Dovecot should be hiding it from list requests - as it does for the .imap index structure. I made a workaround by using the below mail_location setting. This puts the .subscriptions file above the imap folder structure and hence outside the list scope. mail_location = mbox:~/imap:INBOX=~/mbox:CONTROL=~:INDEX=~/.imap You'll note I have also moved the .imap index. This works, but the full path to the index files has extra layers of .imap. For example, if a folder tree of imap/A/B/C/D exists, where D is the actual mbox format message file, then the index files are stored in .imap/A/B/C/.imap/D. Don't know if this is a bug or I'm misunderstanding something. Can you provide any insight or better solutions for either issue? Some clients are also using iPhones and/or roundcubemail for web access. Those do not have the .subscriptions issue. Raan

[Dovecot] multiple users to same e-mail account with ldap authentication
by Marco Gatti 14 Nov '12

14 Nov '12

Hi, I was looking for a particular case of dovecot configuration I cannot find anywhere. Is there a way dovecot can authenticate via ldap different windows 2008 AD users that have access to the same e-mail account (like user authorization in ms exchange)? For example I want to extend AD schema to let users have 10 email accounts (with multiple domain support). If they are private accounts I think there is no problem at all. But if I want two or more users to access the same mail account what happens? Can I do it with dovecot? Or should I create AD groups and add members to that, to let user access the same mail account? Cheers -- Marco

[Dovecot] Dovecot 2.1.10
by Ralf Zimmermann 14 Nov '12

14 Nov '12

Hi all, I've a problem with dovecot-2.1.10. At time we use dovecot-1.2 without zlib. We setup a new server with dovecot 2.1.10. After syncing the emails everything looks fine. But if we use zlib plugin all new emails have no content. There are a lot of "Error: Maildir filename has wrong S value" log entrys. So we have compiled dovecot-2.0.18 and we use exactly the same configuration. Everything works. What can be our problem with version 2.1.10? Greets Ralf

[Dovecot] dovecot lost mail! Cause?
by Lukas Haase 14 Nov '12

14 Nov '12

Hi, After using dovecot for several years now, today happend something which makes me really feel unconfortable: An email received was just not delivered properly, or, is lost! The mail (from an external server) was sent to two local mailboxes, user1 and user2. user1 received the message but for user2, it *magically* disappeared. MTA is exim4 which definitely processed the messages and handed over to dovecot deliver: 2012-11-12 07:28:21 1TXnVG-00053I-GD SA: [...] id=8644593.887351352701 685934.JavaMail 2012-11-12 07:28:21 1TXnVG-00053I-GD => user1 <user1(a)example.com> R=dovecot T=dovecot_pipe 2012-11-12 07:28:21 1TXnVG-00053I-GD => user2 <user2(a)example.com> R=dovecot T=dovecot_pipe 2012-11-12 07:28:21 1TXnVG-00053I-GD Completed Also, the log of dovecot tells that the mail should have been stored: Nov 12 07:28:21 mail dovecot: deliver(user1): sieve: msgid=<8644593.887351352701685934.JavaMail>: stored mail into mailbox 'INBOX' Nov 12 07:28:21 mail dovecot: deliver(user2): sieve: msgid=<8644593.887351352701685934.JavaMail.orbitz>: stored mail into mailbox 'INBOX' user1 received the mail but user2 not. Since user2 is myself, I *know* that I did not accidently delete any mail or something like that. It was just never received! Disk space is 3GB left, so enough. So I grepped the whole Maildir of user2 for the message ID. There is only one match in the dovecot.index.cache and within that, the most important data of the mail (Message ID, Date, Sender, Receiver, Subject) appears. But apart from that, not a single file! Is there hope to ever find out why what was going wrong here? It feels me veeeeeeeeery unconfortable because from now on I can never be sure any more that all my mails are really received :( :( However, as I said, my mail system processed maybe millions of messages the past 8 years. Although, I can not be sure if that was the case ... :( And help greatly appreciated! Luke PS: Dovecot version 1.2.15 (Debian 6.0.6) with Maildir backend on local harddrive. No NFS, nothing which can go wrong ... PPS: Original log files, just named replaced for privacy.

[Dovecot] Dovecot newbie (migrating from qmail)
by Ajai Khattri 13 Nov '12

13 Nov '12

Ive been using qmail+vpopmail+courier-imap for many years but its time to retire that server so I thought this might be an opportunity to see how I could use Postfix and Dovecot to provide the same services. Im running Dovecot 2.1.9 and Postfix 2.9.4. I have spent a few days reading through some of the docs on the wiki (there's doesn't seem to be any large overview of Dovecot concepts or books so bear with me). Im thinking something simple like passwd-file setup would suffice for me. I want to use completely virtual users. Id like to store mail under /home/vmail/$domain/$user. I think Ive figured out how to do that. But how do I create the maildir? I understand the need to have a mail directory but also a directory for things like sieve - how to specify that? Im thinking the structure would be something like: /home/vmail/$domain/$user/mail <-- mail stored here /home/vmail/$domain/$user/ <-- sieve and other sundry store here Or should the sieve stuff also be under its own folder alongside the maildir? Is it possible to have a separate passwd file per domain? It is possible to combine password and userdb files into one per domain? (I prefer to keep all files related to each domain in its own folder). Also would like to configure Postfix to use dovecot-sasl and I want to use dovecot-lmtp for deliveries. Any good docs / example on those? Later on, I think I want to integrate some kind of virus and spam filtering (amavisd and maybe dspam - anybody used those? would I configure Postfix to handle that or dovecot-lmtp?) Im sure Ill have more questions as I get more complicated but baby steps for now. -- Aj.

[Dovecot] Commercial features in Dovecot future: Object storage, archive
by Timo Sirainen 13 Nov '12

13 Nov '12

Hi all, Dovecot Oy’s web pages at www.dovecot.fi have been updated. The products page lists two features that will be available for commercial licensing, extending the functionality of the basic open-source version of Dovecot. * Storing emails to (high-latency) object storage, initially supporting Amazon S3, Caringo CAStor and Scality. * Email archive storage. See http://www.dovecot.fi/products/index.html for details. I’ve been developing Dovecot for over 10 years now. For a long time it was my primary motivation in life to create the best IMAP server available :) I think I've pretty much accomplished that by now. The future is looking very bright for Dovecot: we will continue the open source development stronger than ever, but in addition, for the long term it needs some additional licensed components that bring the money to cover the cost for future Dovecot development and to be able to build up the support in a professional way. These new features will be added as plugins on top of Dovecot to extend the functionality. Note that I’m not just randomly choosing which features will be open and which will be licensed. Only some specific features will be licensed where my company is going to make money with partnerships and in other measurable ways.

[Dovecot] mbox vs. maildir storage block waste
by Christoph Anton Mitterer 13 Nov '12

13 Nov '12

Hi. I recently mentioned in several posts, that I'd tended to use mbox rather than maildir, because you don't loose so much space (due to always allocating full blocks per maildir file and thus per mail). I made some tests of my archive, which consists of some 3,4 million mails at a total of 42GB). Most of these mails are probably normal sized, but there are also some with bigger attachments. For those who are interested here are the results: I used a 53687091200 B image file (via loop device) and tested ext4 only. btrfs is IMHO not yet ready, I have had often issues with XFS (corruptions), reiser4 is more or less dead and reiser3 is said to have issues (see e.g. its wikipedia article, even though it has that mode for small files which would fit nicely). As you see the number of mails increased a bit, cause I tested over several days... but this is only a very small increase so it shouldn't change the numbers a lot. 1) Original mbox archives (right now in Evolution) mbox exact space: 38122676224 (does not include meta-data) mbox guess space: 44625670144 (includes Evolution meta-data which is several GBs) mbox num mails: 3412999 (occurances of From_ lines) In the following: - image file, 1B-blocks, Used_begin, Used_end, Available_begin, Available_end result out of df -B 1 - mdir exact used space is the sum of du -B 1 for each regular file (i.e. each mdir file) - mdir guess used space du -B 1 on the root dir of the filesystem - mdir num mails: find . type -f | wc -l on the root dir of the filesystem 2) EXT4 with 4096 blocks: image file: 53687091200 1B-blocks: 52844687360 Used_begin: 188555264 Used_end: 45198778368 Available_begin: 49971777536 Available_end: 2444972032 mdir exact used space: 44810866688 mdir guess used space: 45010243584 mdir num mails: 3423296 delta: 6.688190464 G delta / mail: 1953 B 3) EXT4 with 2048 blocks: image file: 53687091200 1B-blocks: 50324295680 Used_begin: 82857984 Used_end: 41598846976 Available_begin: 47557083136 Available_end: 6041094144 mdir exact used space: 41323991040 mdir guess used space: 41516007424 mdir num mails: 3425033 delta: 3.201314816 G delta / mail: 934 B 4) EXT4 with 1024 blocks: image file: 53687091200 1B-blocks: 50314834944 Used_begin: 38287360 Used_end: 39909360640 Available_begin: 47592193024 Available_end: 7721119744 mdir exact used space: 39683908608 mdir guess used space: 39871086592 mdir num mails: 3425033 delta: 1.561232384 G delta / mail: 455 B As you can see, the delta per mail is rather close to the statistically expected values of 2048B, 1024B and 512B. In the end I probably changed my opinion. ~7GB of wasted block space for all my mails is actually quite a lot, but in days of cheap disk space it's acceptable. And with mbox one has IMHO the major disadvantage that mailservers (including dovecot) store some meta-data _in_ it (i.e. in the mails themselves) , which I don't like a lot. I still think about reports that mbox is much faster with full text search (which sounds reasonable)... but therefore one needs probably and database backend anyway. HTH, Chris.

[Dovecot] Invalid Managesieve commands are counted twice
by Christoph Bußenius 12 Nov '12

12 Nov '12

Hi, the Managesieve server closes the connection if it receives an unknown command before authentication: "IMPLEMENTATION" "Dovecot Pigeonhole" "SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave" "NOTIFY" "mailto" "SASL" "PLAIN" "STARTTLS" "VERSION" "1.0" OK "Dovecot ready." --> BOGUS NO "Error in MANAGESIEVE command received by server." NO "Error in MANAGESIEVE command received by server." BYE "Too many invalid MANAGESIEVE commands." Connection closed by foreign host. Note that only one bogus command has been sent by the client, however the server sends two identical error messages. This seems to be a bug in Pigeonhole 0.3.3. In version 0.2.6, the connection was kept open after the error message. This is actually important to us because we use the "sieveshell" utility which is shipped with the Python "managesieve" package. The managesieve.py module always sends a BOGUS command after the TLS handshake. According to its comments, this is done to work around problems with other server implementations: # Some servers send capabilities after TLS handshake, some # do not. We send a bogus command, and expect a NO. If you # get something else instead, read the extra NO to clear # the buffer. typ, data = self._command('BOGUS') (The full source is at http://pydoc.net/managesieve/0.4.2/managesieve) As a result, sieveshell cannot be used with TLS and a current Dovecot/Pigeonhole server.

[Dovecot] Solr 4.0 - lucene - FTS
by Charles Marcus 12 Nov '12

12 Nov '12

Hi Timo, As one who is interested in implementing FTS sometime in the future, I'm curious about what is in store as far as improvements go... Specifically, any plans for implementing immediate/automatic index updates at delivery time? The lack of automatically updated indexes is one downside for its implementation... Also, does the release of Solr 4.0 mean anything for the lucene library used by dovecot? http://www.marketwatch.com/story/lucidworks-congratulates-apache-foundation… Thanks, -- Best regards, Charles

[Dovecot] Sieve puts incoming message into inbox on any problem with submission_host
by Christian Rohmann 12 Nov '12

12 Nov '12

Hello dovecot-users, I have a question/suggestion regarding the submission_host feature of the lda (either via dovecot-lda binary or lmtp) in combination with sieve. When trying to deliver message to a mailbox and this message has a sieve redirect action applied to it, dovecot is using the configured smtp server to forward the message just fine. Unfortunately, if the server configured for submission is unavailable, returns an error or cannot be found via DNS, sieve will simply put the message into the inbox and be done with it: --- dovecot.log --- dovecot: lda(user1): Error: lmtp client: DNS lookup of idonotexist.example.com failed: Name or service not known dovecot: lda(user1): Error: sieve: msgid=unspecified: failed to redirect message to <user2> (refer to server log for more information) dovecot: lda(user1): sieve: msgid=unspecified: stored mail into mailbox 'INBOX' dovecot: lda(user1): Error: sieve: execution of script /mailboxes/user1/.dovecot.sieve failed, but implicit keep was successful (user logfile /mailboxes/user1/.dovecot.sieve.log may reveal additional details) --- /dovecot.log --- The same applies to vacation messages being sent out. Especially with an (unconditional) redirect action, users don't expect to find messages in their inbox. Also problems with the submission_host could very much be temporary and a little delay in delivering a message is better then putting it somewhere the user doesn't expect a message to be. Is there any way to change the behavior of dovecot or the sieve plugin to tempfail in case a message cannot be sent out? I know that with multiple sieve actions it gets more complicated as there could be corner cases were the first message can be sent via the submission server and another message produced by the same sieve script cannot. I'd love sieve to behave like this: a) if submission host is unreachable (hostname wrong, timeout, ...) -> tempfail b) if submission host returns 4xx error -> tempfail c) if submission host returns 5xx error -> fail(-save) and just drop the message into inbox or even have an option to reject the message completely in this case. In case of a tempfail response, the mta simply queues the message and tries again later. In case of a permanent fail the mta will create a bounce message to in form the sender. Regards and have a great weekend, Christian

Re: [Dovecot] LDA without lookup as non-root?

Timo, Sorry I didn't see your response until now >> 3) The interesting part -- I am invoking LDA from Maildrop. See: >> http://thread.gmane.org/gmane.mail.imap.dovecot/65473 > So >> when invoked, Maildrop has already dropped to the destination UID/GID >> and the needed paths are available in the environment. However, using >> as many permutations of calling LDA as I can think of (based on >> http://wiki2.dovecot.org/LDA ), I always get this: >> >> (command line usage error. Command output: lda: Fatal: Couldn't lookup >> our username (uid=2500) ) > > Set USER environment. Sorry, would you mind being more specific? If you see my follow-up posts on this thread, I found a source file with this error message in it (link below) and reading that code, there is no way to avoid this error for non-system users (uid's) if you don't use -d.

[Dovecot] quota recalc does not work
by Adrian Stoica 09 Nov '12

Hi I upgraded dovecot from 2.0 to 2.1 , and now i face the quota recalc problem. All settings are keep in mysql Before , after a change in mailbox.quota field, i run doveadm quota recalc and all was ok , but now that command doesn't do anything. After i change a quota for a user , i have to restart dovecot to get the new quota , or do a "doveadm reload" instead of recalc. And the doveadm quota recalc -A" give me back a lot of "doveadm(username): Info: User no longer exists, skipping" Any thoughts ? # 2.1.10: /usr/dovecot21/etc/dovecot/dovecot.conf # OS: Linux 2.6.35.4 i686 auth_cache_negative_ttl = 1 secs auth_cache_size = 2 M auth_failure_delay = 4 secs auth_mechanisms = plain login digest-md5 cram-md5 auth_worker_max_count = 100 base_dir = /var/run/dovecot/ default_client_limit = 4096 default_internal_user = vmail default_login_user = nobody default_process_limit = 256 deliver_log_format = mail delivery from=%f subject=%s msgid=%m: %$ dict { acl = mysql:/usr/dovecot21/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no first_valid_uid = 1 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes listen = * mail_location = maildir:~/Maildir mail_plugins = " quota acl trash notify mail_log" 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 namespace { hidden = no list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes list = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / subscriptions = yes type = private } passdb { args = /usr/dovecot21/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl autocreate = Trash autocreate2 = Drafts autocreate3 = Sent autosubscribe = Trash autosubscribe2 = Drafts autosubscribe3 = INBOX autosubscribe4 = Sent mail_log_events = delete mailbox_delete mailbox_rename mail_log_fields = box subject from msgid size quota = maildir:User quota quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=95%% quota-warning 90 %u quota_warning3 = storage=85%% quota-warning 85 %u sieve = ~/.dovecot.sieve sieve_dir = ~/sieve trash = /usr/dovecot21/etc/dovecot/dovecot-trash.conf.ext } postmaster_address = postmaster(a)dacris.net protocols = imap quota_full_tempfail = yes rejection_subject = Rejected: %s: %r service auth { unix_listener auth-client { mode = 0666 user = vmail } unix_listener auth-userdb { mode = 0666 user = vmail } } service dict { unix_listener dict { user = vmail } } service imap-login { process_min_avail = 4 } service imap-postlogin { executable = script-login /bin/imap.sh unix_listener imap-postlogin { mode = 01232 } } service imap { executable = imap imap-postlogin process_limit = 1024 vsz_limit = 1 G } service quota-warning { executable = script /bin/quota_warning.sh unix_listener quota-warning { user = vmail } user = vmail } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /usr/dovecot21/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = " quota acl trash notify mail_log sieve autocreate" } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 20 mail_plugins = " quota acl trash notify mail_log imap_quota imap_acl" } dovecot-sql.conf.ext: password_query = SELECT password FROM mailbox WHERE \ username = '%Ln' AND domain = '%Ld' AND \ active = '1' user_query = SELECT CONCAT('/srv/vmail/',mailbox.domain,'/%Ln') AS 'home' ,'98' AS 'uid', '98' AS 'gid' , \ CONCAT('*:storage=', mailbox.quota,'M') AS quota_rule ,"Trash:storage=+50M" AS quota_rule2 FROM mailbox WHERE \ mailbox.username = '%Ln' AND mailbox.domain = '%Ld' AND \ mailbox.active = '1' iterate_query = SELECT username AS user , domain FROM mailbox WHERE active = '1'

[Dovecot] Mails don't get deleted after POP3
by cullinan＠rocketmail.com 09 Nov '12

09 Nov '12

Hi, there! Well, I am new to dovecot, so please be patient with me: I have a virtual server and want to setup simple mail delivery. postfix, saslauthd and dovecot basically work fine. The only open issue is, that (I guess) dovecot doesn't remove the mail when it's retrieved via pop3 from the server. It keeps sending me the same emails again and again. (The mail client (Thunderbird) is configured to remove the messages from the server - it was working already.) I guess that dovecot cannot write to some files / has problems with write permissions. But it doesn't tell me anything... Can you tell me, what configuration might be wrong or how can I enable more debugging to see what dovecot is doing after the mails got sent out via pop3? Here is the configuration: # dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.38-8-server x86_64 Ubuntu 11.04 log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 pop3s login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login mail_privileged_group: mail mbox_write_locks: fcntl dotlock mail_executable: /usr/lib/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/modules/pop3 auth default: passdb: driver: pam userdb: driver: passwd -----8<----- # dovecot -a # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.38-8-server x86_64 Ubuntu 11.04 base_dir: /var/run/dovecot log_path: info_log_path: log_timestamp: %Y-%m-%d %H:%M:%S syslog_facility: mail protocols: pop3 pop3s listen: * ssl_listen: ssl: yes ssl_ca_file: ssl_cert_file: /etc/ssl/certs/dovecot.pem ssl_key_file: /etc/ssl/private/dovecot.pem ssl_key_password: ssl_parameters_regenerate: 168 ssl_cipher_list: ssl_cert_username_field: commonName ssl_verify_client_cert: no disable_plaintext_auth: yes verbose_ssl: no shutdown_clients: yes nfs_check: yes version_ignore: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login login_user: dovecot login_greeting: Dovecot ready. login_log_format_elements: user=<%u> method=%m rip=%r lip=%l %c login_log_format: %$: %s login_process_per_connection: yes login_chroot: yes login_trusted_networks: login_process_size: 64 login_processes_count: 3 login_max_processes_count: 128 login_max_connections: 256 valid_chroot_dirs: mail_chroot: max_mail_processes: 512 mail_max_userip_connections: 10 verbose_proctitle: no first_valid_uid: 500 last_valid_uid: 0 first_valid_gid: 1 last_valid_gid: 0 mail_access_groups: mail_privileged_group: mail mail_uid: mail_gid: mail_location: mail_cache_fields: mail_never_cache_fields: imap.envelope mail_cache_min_mail_count: 0 mailbox_idle_check_interval: 30 mail_debug: no mail_full_filesystem_access: no mail_max_keyword_length: 50 mail_save_crlf: no mmap_disable: no dotlock_use_excl: yes fsync_disable: no mail_nfs_storage: no mail_nfs_index: no mailbox_list_index_disable: yes lock_method: fcntl maildir_stat_dirs: no maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: no maildir_very_dirty_syncs: no mbox_read_locks: fcntl mbox_write_locks: fcntl dotlock mbox_lock_timeout: 300 mbox_dotlock_change_timeout: 120 mbox_min_index_size: 0 mbox_dirty_syncs: yes mbox_very_dirty_syncs: no mbox_lazy_writes: yes dbox_rotate_size: 2048 dbox_rotate_min_size: 16 dbox_rotate_days: 1 mail_drop_priv_before_exec: no mail_executable: /usr/lib/dovecot/pop3 mail_process_size: 256 mail_plugins: mail_plugin_dir: /usr/lib/dovecot/modules/pop3 mail_log_prefix: %Us(%u): mail_log_max_lines_per_sec: 10 imap_max_line_length: 65536 imap_capability: imap_client_workarounds: imap_logout_format: bytes=%i/%o imap_id_send: imap_id_log: imap_idle_notify_interval: 120 pop3_no_flag_updates: no pop3_enable_last: no pop3_reuse_xuidl: no pop3_save_uidl: no pop3_lock_session: no pop3_uidl_format: %08Xu%08Xv pop3_client_workarounds: pop3_logout_format: top=%t/%p, retr=%r/%b, del=%d/%m, size=%s dict_db_config: dict_process_count: 1 managesieve_max_line_length: 65536 managesieve_logout_format: bytes=%i/%o managesieve_implementation_string: dovecot auth default: mechanisms: plain realms: default_realm: cache_size: 0 cache_ttl: 3600 cache_negative_ttl: 3600 executable: /usr/lib/dovecot/dovecot-auth user: root chroot: username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ username_translation: username_format: master_user_separator: anonymous_username: anonymous krb5_keytab: gssapi_hostname: winbind_helper_path: /usr/bin/ntlm_auth failure_delay: 2 verbose: no debug: no debug_passwords: no ssl_require_client_cert: no ssl_username_from_cert: no use_winbind: no count: 1 worker_max_count: 30 process_size: 256 passdb: driver: pam args: deny: no pass: no master: no userdb: driver: passwd args: -----8<----- Please let me know if you need more.

[Dovecot] Dovecot ok for port 110, but not for SSL (beginner asking)
by ycc_Swe 09 Nov '12

Hello, I just installed Dovecot. It works for plaintext autorization, port 110. It has connected with Telnet, Thunderbird and an on-line pop3 client. Telnet: +OK Dovecot ready. user nnnnn -ERR Unknown command. user nnnnn +OK pass xxxxxxxxxx +OK Logged in. stat +OK 1 1553 retr 1 +OK 1553 octets Return-path: <sssssss(a)hotmail.com> Envelope-to: nnnnnn(a)mydomain.com Delivery-date: Tue, 06 Nov 2012 12:02:28 +0100 Received: from bay0-xcvxcv-xvxcv.bay333.hotmail.com ([123.123.123.123]) by deb7.pc with esmtp (Exim 4.80) But when I try ssl (port 995) with an on-line pop3 client, it will not work: /var/log/mail.log Nov 7 02:46:55 deb7 dovecot: pop3-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=12.12.12.7, lip=123.123.123.123, TLS: Disconnected, session=<Iza75N3NlABBNykH> Nov 7 02:46:56 deb7 dovecot: pop3-login: Disconnected (no auth attempts in 1 secs): user=<>, rip=12.12.12.7, lip=123.123.123.123, TLS: Disconnected, session=<nWTF5N3NlQBBNykH> root@deb7:~# doveconf -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-3-686-pae i686 disable_plaintext_auth = no mail_gid = mail mail_location = mbox:~/mail:INBOX=/var/mail/%u namespace inbox { inbox = yes location = prefix = } passdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap pop3" ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } I know very little about mail and ssl.

The following two files contain ssl keys: ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem I have tried changing the ssl parameter ("yes", "required") in 10-ssl.conf but with no change except that port 110 login becomes disabled. As you can see I am a beginner with Dovecot, I hope it is still OK to ask on this mailing list.

The current stable release is RHEL 6.3, released in June 2012. What is the valid reason preventing you from upgrading to the 6.x distribution? The packages in general in 6.x are 5 years newer than 5.x. And given the fact that RHEL runs miles behind the bleeding edge, you're way behind the curve even with a recent RHEL distribution. You can probably find a much newer version of Dovecot in an RPM somewhere, and Postfix for that matter. But it would be better for you if you simply upgraded to RHEL 6.3. -- Stan

Is there a way I can have something like the following setup: 192.168.0.2 port 110/143, with no starttls/ssl 192.168.0.3 port 110,995/143,993 with starttls/ssl 192.168.0.4 port 110,995/143,993 with starttls/ssl I am looking to setup dovecot so that some IPs will run without any notion of SSL whereas other IPs will run with with ssl/starttls available, each with its own certs

[Dovecot] pop3 exim4 dovecot
by Patrick Shirkey 08 Nov '12

08 Nov '12

Hi, I have an exim4 and dovecot system. The system has multiple accounts. Exim4 is receiving emails in the /var/mail/user files and dovecot is configured to use /home/user/mail (mbox) folder. I have one account that dovecot is not processing replies/bounces/etc... The data is being written in the /var/mail/user file by exim4 but as far as dovecot is aware there is nothing in the pop3 inbox. Can anyone suggest how I can enable dovecot to know that the data is in the /var/mail/user file and deliver it to the pop3 inbox for this account? -- Patrick Shirkey Boost Hardware Ltd

[Dovecot] v2.2.alpha1 released
by Timo Sirainen 08 Nov '12

08 Nov '12

http://dovecot.org/releases/2.2/alpha/dovecot-2.2.alpha1.tar.gz http://dovecot.org/releases/2.2/alpha/dovecot-2.2.alpha1.tar.gz.sig I wanted to start stabilizing v2.2 release some months ago already, but I somehow got stuck adding more and more features. Now it looks like all of the necessary API changes are done, so everything I'm planning on near future can still be added to v2.2 without major changes. The redesigned dsync hasn't had much testing yet, so avoid running it with important mails. Would be nice if people started testing and reporting any bugs. I was going to create some kind of a test suite for testing all the possible syncing combinations and also doing some random stress testing, but I haven't had time for that yet. The new dsync supports doing very fast syncs by saving the resulting state and giving it as command line parameter to the next sync. So for example doveadm sync -s "" > new-state saves the state and doveadm sync -s `cat new-state` continues from the saved state. The replicator code doesn't yet support this. * When creating home directories, the permissions are copied from the parent directory if it has setgid-bit set. For full details, see http://wiki2.dovecot.org/SharedMailboxes/Permissions * "doveadm auth" command was renamed to "doveadm auth test" * IMAP: ID command now advertises server name as Dovecot by default. It was already trivial to guess this from command replies. + Implemented IMAP MOVE and BINARY extensions + Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions (by Stephan Bosch). + Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes to be enabled. + Redesigned and rewritten dsync. The new design makes the syncing faster, more reliable and more featureful. The new dsync protocol isn't backwards compatible with old dsync versions (but is designed to be forwards compatible with future versions). + All mailbox formats now support per-user message flags for shared mailboxes by using a private index. It can be enabled by adding :INDEXPVT=<path> to mail location. This should be used instead of :INDEX also for Maildir/mbox to improve performance. + Improved mailbox list indexes. They should be usable now, although still disabled by default. + Added LAYOUT=index. The mailbox directories are created using their GUIDs in the filesystem, while the actual GUID <-> name mapping exists only in the index. + LMTP proxy: Implemented XCLIENT extension for passing remote IP address through proxy.

Re: [Dovecot] Android ICS stock client and IMAP Capability issue.
by Massimiliano Cianelli 08 Nov '12

Hi, Yes w/o prefix work as expected, try to add a prefix like courier does (eg. Inbox.) It will not work as expected. Due I'm upgrading an old installed server, I've to keep everything as much transparent I can... it includes IMAP folder and subscription. Looking at that I've encountered that issue, and analyzed for fix it (thank you open source), not everyone will want to use/use k9.. but you can be 100% sure the stock client is there. Due that Google act like BlackBerry, Microsoft,etc.. (hovewer they will not fix it soon, or really respect the rfc), it's much simple add Namespace on prelogin banner then wait or have to tell someone to install another client for that mailbox. I didn't know the history, but looking at change log seems that idle as been put back to prelogin client for some kind of compatibility with their service. Anyway, the most important reason that got me to subscribe the mailing list for write those emails, is share with the community that problem and provide a solution.. for someone in the future that have the same problem and will search on internet for a solution (like I've does.. before analyze it on my own). If the workaround will be added to the wiki or will be put in the source.. the important thing is that there is a solution simple and fast (two.. the source modify, and the configuration file) and someone can find it.. (Sarcastic) And if the mayans were right we can't wait for google to fix it :p Best Regards Sent from Galaxy Nexus Robert Schetterer <rs(a)sys4.de> ha scritto: >Am 07.11.2012 08:13, schrieb Massimiliano Cianelli: >> Hello, >> >> My phone: >> Android ics 4.1.2 on galaxy nexus. >> And yes, stock mean the default client that come with the os in IMAP mode. >> >> I already know about that configuration parameter, but it will display two time namespace in postlogin capabilities, and so I like much more to adjust the source code to fix the issue. >> >> Yes there is k9 but I didn't like it too much, I prefer the stock client and is much important to keep compatibility with stock client then user-installed client. >> >> About the issue on Google code, there is thr issue on google code... but Google is a lot slow in fixing those things. >> http://code.google.com/p/android/issues/detail?id=1811 >> >> In a few hour I'll update the issue noticing where is hidden the problem. >> >> Regards >> Sent from Galaxy Nexus > >Hi , i shortly tested this with android sdk jelly bean 4.1.1 and "my >setup" dovecot 2.1.10 with included orginal android mail app in imap mode, >,leaving IMAP prefix blank, everything works as expected, no double >shown inbox, namespace problems etc >so you might have to fit your namespace setup. >Also you might follow allready given advice from here. > >Anyway , i understand you using "stock client" >but you have to understand that the producers of mail clients >optimize their stuff fitting best in their own server structure >making money with it, therefor their motivation coding better imap code >is not very high, same case is for outlook and microsoft >however, i would say, fixing bugs is on the google site here, looks like >there is patch >at >http://code.google.com/p/android/issues/detail?id=1811 >and the issue seems long known > >i dont see any hard relation to dovecot in this case >meanwhile using k9mail seems the best way to workaround >there are lots of other bugs around android versions >over the years i dont expect google to fix them > > >> >> Robert Schetterer <rs(a)sys4.de> ha scritto: >> >>> Am 06.11.2012 07:08, schrieb Ben Morrow: >>>> At 6AM +0100 on 6/11/12 you (Massimiliano Cianelli) wrote: >>>>> Hi, >>>>> >>>>> My setup: >>>>> Dovecot 2 latest, installed to replace courrier IMAP, and off course >>>>> configured with the dot separator and all folder under INBOX.*. >>>>> >>>>> The problem: >>>>> My phone was driving me mad during the test, due that it will only >>>>> recognize Inbox. >>>>> >>>>> How found the solution: >>>>> I've started sniffing IMAP traffic on my server and ended up with one >>>>> difference: >>>>> On courier it ask for namespace, on dovecot it won't. >>>>> >>>>> I gives a better look, and noticed that courier show namespace >>>>> capability on prelogin banner, adding it too solved the problem. >>>>> >>>>> Reason: >>>>> Android ICS stock client seems do not honor the capability gived after >>>>> the login. >>>> >>>> See http://wiki2.dovecot.org/Upgrading/2.0?highlight=%28capability%29 ; >>>> you need to set imap_capability and/or get your client fixed. >>>> >>>> Ben >>>> >>> >>> Hi, first ,what is the exact meaning of >>> >>> "Android ICS stock client" >>> >>> do you mean default included email client in standard android in imap >>> mode, when yes, which version of Android , i like to test my own >>> however is there changelog/code etc at google for this behave? >>> >>> conf example >>> >>> # Override the IMAP CAPABILITY response.

hello, I'm using dovecot 2.0.16 and i would like to use acl for subfolder. The file dovecot-acl is well written in both folder test and the subfolder test/Test : cat /home/user2/Maildir/.test.Test/dovecot-acl user=user1 ilrws cat /home/user2/Maildir/.test/dovecot-acl user=user1 ilprws When user1 want to list, the folder test is well shown, but not the subfolder test/Test.

[Dovecot] Auth USER lookup failed
by Angel L. Mateo 07 Nov '12

07 Nov '12

Hello, I'm running dovecot 2.1.9 and I'm trying to configure shared folders. So, as described at http://wiki2.dovecot.org/SharedMailboxes/Shared I have configured a namespace like this: namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = yes } In one user (user1) I have configured ACLs so another one (user2) has access to a folder. Now, I want to susbscribe user2 to this folder. The problem I have is that whenever I try to list folders for this user (running thunderbird client) I get a panic and an error in the dovecot server (I have attached the complete log). The error says: Nov 6 11:58:56 myotis30 dovecot: auth: Error: userdb(user1): client doesn't have lookup permissions for this user: userdb uid (113246) doesn't match peer uid (14585) (change userdb socket permissions) Nov 6 11:58:56 myotis30 dovecot: auth: Debug: master out: FAIL#0112 Nov 6 11:58:56 myotis30 dovecot: imap(user2): Error: user user1: Auth USER lookup failed Nov 6 11:58:56 myotis30 dovecot: imap(user2): Debug: auth input: Nov 6 11:58:56 myotis30 dovecot: imap(user2): Error: Couldn't create namespace 'shared/' for user user1: userdb didn't return a home directory, but plugin setting quota used it (%h): dict:User quota::file:%h/Maildir/dovecot.quota It seems that imap process running for user2 is trying to a user lookup that fails. So I have manually tried it root@myotis30:/etc/dovecot/conf.d# sudo -u user2 doveadm user user2 userdb: user2 home : <homeDirectory> uid : 14585 gid : 404 root@myotis30:/etc/dovecot/conf.d# sudo -u user2 doveadm user user1 doveadm(user2): Error: user user1: Auth USER lookup failed doveadm(user2): Error: userdb lookup failed for user1 I have checked the socket permissions, but they are 0666 (if I'm looking the right socket): root@myotis30:/etc/dovecot/conf.d# ls -l /var/run/dovecot/auth-userdb srwxrwxrwx 1 dovecot root 0 nov 6 11:43 /var/run/dovecot/auth-userdb In fact, I have tried to put all sockets with permissions 0666 and 0777, but the error persists.

[Dovecot] LDAP congestion
by Bernhard Schmidt 07 Nov '12

07 Nov '12

Hello, I've been asked to have a look at a misbehaving mail server of some colleagues today where almost all logins where failing or excessively delayed, while the LDAP database itself was pretty fast. They run Dovecot 1.2.11 (yes, I know, stoneage) against an LDAP server run by a 3rd party, auth_bind=yes (required). The problem is that this third party LDAP server delays bindResponse 3 seconds when the password is wrong. A user wanted to login every 2-3 seconds this morning with the wrong password, which effectively killed the system because the LDAP connection was mostly stalled waiting for the auth timeout. >From a previous discussion with Timo I know that bindRequests cannot be parallelized in LDAP, so the problem does not come completely unexpected. Other than removing the failure delay in the LDAP server, is there anything one can do? If there is any change in newer Dovecot versions about that please tell me so I can encourage them to upgrade, but I haven't seen anything in the changelog. Any way to get several LDAP workers/connections for passdb in parallel? Thanks, Bernhard

[Dovecot] "starting" dovecot
by Dave Abrahams 07 Nov '12

07 Nov '12

My system never issues the "dovecot start" command. I do, however, run /usr/local/libexec/dovecot/imap on port 9xxx. I talk to the server through port 9xxx and through the preauth tunnel. Is this arrangement OK? Are there some things that will only work if "dovecot" is invoked?

[Dovecot] Modifying mailbox GUIDs?
by Faheem Patel 07 Nov '12

07 Nov '12

Greetings all, I can view a mailbox's GUID like so: doveadm mailbox status -u guid However, how may I *modify* a mailbox GUID? Can this be done using doveadm or some other tool? If not, how may I go about modifying the dovecot.mailbox.log (where I assume GUID data is stored)? My specific use case has to do with me wanting to modify an existing mailbox's GUID so that its messages are mirrored into a folder of the same name using "dsync mirror". (As we know, dsync utilizes GUIDs to determine mailbox uniqueness) Thanks! -- - Faheem

[Dovecot] Error: Internal quota calculation error
by Micah Anderson 07 Nov '12

07 Nov '12

Hello, I'm using 2.1.7 with seive and mysql quotas. We had an outage the other day where the database server where quotas are stored was not available for a short period of time. In dovecot land, the following types of errors occured in that scenario: Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: Internal quota calculation error Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: sieve: msgid=<20122132765181x.ABCCE457(a)example.com>: failed to store into mailbox 'Trash': Internal error occurred. Refer to server log for more information. [2012-10-26 22:19:01] Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: sieve: script /maildir/e/example/.dovecot.sieve failed with unsuccessful implicit keep (user logfile /maildir/e/example/.dovecot.sieve.log may reveal additional details) I expect that there would be quota calculation errors as dovecot could not reach the database server, but what worried me was the 'failed to store into mailbox' message from sieve. The 'Trash' mailbox in this particular seive script is the correct location for the message to be filed into, but the worrisome message is the 'failed with unsuccessful implicit keep'. I looked through all the message-ids that reported this error and I found that the messages were properly delivered in the end, so this might be some issue interacting between sieve, dovecot and quota and just causing a scary message that can be ignored? thanks for any information you can provide, dovecot is great! micah --

[Dovecot] how to best import Evolution/Thunderbird mail into dovecot?
by Christoph Anton Mitterer 07 Nov '12

07 Nov '12

Hi. I'm migrating all my mail archive (some 60 GB) from Evolution (which is really a broken piece of software) into dovecot. Now I face the problem how to do this best... Evolution (which is still a old 2.32.x version) itself uses mbox files, in a special hierarchical structure to allow subfolders and that like. It also stores it's own status info in X-Evolution and X-Evolution-Source mail headers. Unfortunately,... much of the mail was earlier from a Thunderbird installation, which uses it's own status headers (X-Mozilla*) that were not recognised by Evolution. I have no idea which mbox subformat was always used throughout the different programs and versions... 1) Any way to check for that? To make things worse... Thunder(burden) seems to have used a modified From_ line syntax... "^From -<address> <date>$" Ideally I'd like migrate all mail into dovecot (for storage reasons again, mbox) retaining the different status flags (read, forwarded, etc.) and getting rid of the proprietary headers (of course only when they were. First thing I tried was to simply copy mail within Evolution (i.e. dragging&dropping it from the local folders to the IMAP folders from dovecot). - that preserves the status from Evolution, but doesn't restore that from Thunderbird - it clutters up the information of all From_ lines... "<address> <date>" becomes "<address of my default evolution account> <now>" - neither does it handle the special Thunderbird From_ lines - neither does it remove the Thunderbird or the X-Evolution-Source headers - if Evolution has already had corrupted index files (and this is extremely likely... as it happens even immediately during recreating all of them)... so I may loose mail So my idea was that I need a program that: - can parse all the different mbox formats (those that use the quoted ">From" style and those that use Conent-Length) - can differentiate message headers from body (so that I can drop the proprietary headers and replace them by what dovecot uses as headers) - must of course understand multiline message headers 2) Any idea for a tool like that? The meaning of the X-Evolution and X-Mozilla* headers are easy to find on the web.... so I can convert them. So I basically "just" need a tool that parses all kinds of mbox formats... allow me to drop/add headers... and spits out the rest unmodified. 3) dovecot uses some special headers like X-UID and X-IMAPD... will it create these on it's own, the first time it processes the new mbox file? I mean these headers won't be there after creation. 4) Should I drop out (during) conversion... any other mail headers.. that dovecot uses as it's own? Thanks, Chris.

Hello, My phone: Android ics 4.1.2 on galaxy nexus. And yes, stock mean the default client that come with the os in IMAP mode. I already know about that configuration parameter, but it will display two time namespace in postlogin capabilities, and so I like much more to adjust the source code to fix the issue. Yes there is k9 but I didn't like it too much, I prefer the stock client and is much important to keep compatibility with stock client then user-installed client.

[Dovecot] sieve
by Christian Rößner 06 Nov '12

06 Nov '12

Hi, is there a sieve option that can reject a mail directly without creating a new mail and sending that out? I know about reject "Reject message goes here"; but I am looking for a mechanism that can reject Mail. Postfix can use reject_unverified_recipient to connect to LMTP and ask if a mail would successfully be enqueued and will return the status gotten from the LMTP server if not. Chances are high that the mechanism would work, too, if Dovecot would know about the sieve rule, while getting a connection on LMTP. Does Dovecot know all rules at this point or is sieve handled after the mail has already been accepted?

[Dovecot] Android ICS stock client and IMAP Capability issue.
by Massimiliano Cianelli 06 Nov '12

06 Nov '12

Hi, My setup: Dovecot 2 latest, installed to replace courrier IMAP, and off course configured with the dot separator and all folder under INBOX.*. The problem: My phone was driving me mad during the test, due that it will only recognize Inbox. How found the solution: I've started sniffing IMAP traffic on my server and ended up with one difference: On courier it ask for namespace, on dovecot it won't. I gives a better look, and noticed that courier show namespace capability on prelogin banner, adding it too solved the problem. Reason: Android ICS stock client seems do not honor the capability gived after the login. Request: Maybe is possible to put namespace capability in prelogin banner for the next version? That will solve trouble with a setup like the mine and android stock email client. Thank you, Best regards Sent from Galaxy Nexus

[Dovecot] Quota
by Christian Rößner 05 Nov '12

05 Nov '12

Hi, is it possible to ask Dovecot for a users quota by talking to the Dovecot server over TCP? I know about doveadm quota -u <user>, but I would like to know, if I can query for that over a network connection (on the Postfix ML they suggested writing a policy service that checks quota. Postfix is not always on the same server as Dovecot is). Does the LMTP protocol give that information somehow? I am not so familiar with LMTP. Or some Unix-Socket to query that could also be configured as inet_listener?

Hi. Even new mails delivered by my MDA don't get the ,S= and ,W= fields set... (but when I "upload" a mail via IMAP to dovecot, they are set) Is there some place in dovecot where I need to enable this? Or would it be the MDA that has to calculate and set this already when placing a file in ./new? Thanks, Chris.

I don't know if Dovecot takes advantage of this in any way though. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] dovecot dimensioning

01 Nov '12

Hi All, first post here, nice to meet you :) I've been using dovecot + postfix + clamav + spamassassin for years but always with few users. Now i must build a server for 1500 users, they will use various email software (thunderbird, outlook, ..) the webmail (i'm not sure if squirrelmail or roundcube) and blackberry devices (with the BIS service). There will be around 1000 domains (virtual_domains) and postfix will read its users and domains from mysql. Let's say that they will send and receive around 5000 emails per hour (10K in total per hour). I was thinking to use karspersky server instead of clamav. I already have the hardware, it is a server with 4 physical cpu (Intel Xeon E5504 @ 2.00GHz) and 24 gb of ram, do you think it is enough ? Thanks for supporting, regards and have a nice day, Mike

What should be changed? Ok - I read the patch, and modified the LIBDOVECOT_STORAGE section accordingly.

[Dovecot] Pigeonhole 3.3 broken against Dovecot 2.1.10
by Daniel L. Miller 01 Nov '12

I'm compiling as I normally do. The config line for Dovecot is: configure --with-ldap --with-ssl --with-bzlib --with-zlib --with-stemmer --with-lucene --with-ldap followed by make & make install Then a 'configure' for Pigeonhole, followed by make, yields: libtool: link: gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast

Hello, I have here a problem with managesieve.

[Dovecot] IMAP proxy between Office 365 client/Sun Messaging Server
by John Dalbec 31 Oct '12

31 Oct '12

I would like to be able to migrate messages from existing end-user accounts on Sun Messaging Server to Office 365 using an administrator login and password. Unfortunately the migration tool for Office 365 doesn't support SASL AUTHENTICATE PLAIN login. The online documentation I've found suggests that I should be able to configure dovecot as an IMAP proxy and have it log in to Sun Messaging Server with AUTHENTICATE PLAIN and encode_base64("user\0admin\0adminpw") in response to a login from the Office 365 migration tool. I'd like to configure dovecot to run only the IMAP proxy if possible. I was thinking of setting all accounts to use the same (strong) password in the proxy. Would anyone be willing to share a sample configuration? Thanks, John Dalbec ellucian Luminis system administrator Youngstown State University

[Dovecot] Unable to get Managesieve working
by Cliff Dunn 31 Oct '12

31 Oct '12

I have Roundcube webmail (v. 0.8.2) running with the managesieve plugin (v. 5.1). I am able to create sieve rules without any problems in Roundcube, but incoming mail is not being processed with the rule I specify. I suspect there is something that isn't configured correctly in dovecot, but unfortunately I am unable to find a resolution online and my very limited knowledge of dovecot isn't allowing me to solve this problem on my own. I am including my dovecot config below. Please keep my knowledge level in mind when suggesting options and let me know if there is any other information I can provide to help troubleshoot the problem.

[Dovecot] lmtp out of memory - raw backtrace
by Daniel Parthey 31 Oct '12

31 Oct '12

Hi, Our setup: - 4 hosts with director and mailbox instance - delivery via director lmtp into mailbox lmtp - mailbox format: mdbox - storage on NFS - OS: Linux 2.6.32-44-server x86_64 Ubuntu 10.04.4 LTS - Dovecot 2.1.10 - Pigeonhole 0.3.3 We're getting strange "out of memory" lmtp errors/backtrace with dovecot 2.1.10 accompanied by high load caused caused by a lot of lmtp deliveries to one user. First action would be to increase vsz_limit to a higher value, but I just want to make sure there is no bug - before blindly increasing this limit.

[Dovecot] POP3 Proxy : user format not accepted
by Christian Gregoire 30 Oct '12

30 Oct '12

Hello, I want to use Dovecot as a POP3 proxy (http://wiki.dovecot.org/HowTo/ImapProxy) All is working fine on my sample platform, except that I have plenty (several thousands) of users that login using local_part#domain, instead of local_part@domain, which is an old setting on my POP3 server. And in that case, Dovecot returns 'Authentication failed'. Here is my proxy table : mysql> select * from tbl_proxy; +--------------------+-------------+--------------------+ | user | host | destuser | +--------------------+-------------+--------------------+ | christian(a)mydom.fr | 10.10.100.1 | christian(a)mydom.fr | | christian#mydom.fr | 10.10.100.1 | christian(a)mydom.fr | +--------------------+-------------+--------------------+ If I login on the Dovecot proxy with the '@' version, everything is fine : root : ~> telnet 10.10.100.24 110 Trying 10.10.100.24... Connected to 10.10.100.24 (10.10.100.24). Escape character is '^]'. +OK Dovecot ready. user christian(a)mydom.fr +OK pass azerty42 +OK christian#mydom.fr has 3 messages (3561 octets) And MySQL logs show the query : 121030 12:55:28 3 Query SELECT NULL AS password, host, destuser, 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS proxy, 'Y' AS nopassword FROM tbl_proxy WHERE user = 'christian(a)mydom.fr' If I login on the Dovecot proxy with the '#' version, it fails : root : ~> telnet 10.10.100.24 110 Trying 10.10.100.24... Connected to 10.10.100.24 (10.10.100.24). Escape character is '^]'. +OK Dovecot ready. user christian#mydom.fr +OK pass azerty42 -ERR Authentication failed. And nothing shows up the the MySQL logs. If I login directly on the POP server with the same credentials, no problem : root : ~> telnet 10.10.100.1 110 Trying 10.10.100.1... Connected to 10.10.100.1 (10.10.100.1).

Authenticate yourself. user christian#mydom.fr +OK Password required for christian#mydom.fr pass azerty42 +OK christian#mydom.fr has 3 messages (3561 octets) Any idea ? Is the '#' not internally supported in the user login by Dovecot ? Thanks in advance. Christian

[Dovecot] Dovecot does not update acl_shared_dict file
by Chris Smith 30 Oct '12

30 Oct '12

Hi all, Firstly, thanks for all your effort with this software. Much appreciated. I am having a slight issues trying to enable reading of other users mailboxes. The docs are a little sparse for those that aren't mailadmin heros, I wonder if anyone could please help me see where I am going wrong. I would like to allow some users to list and read the mailboxes of others. E.g: When User1 logs in, they are presented with a list of their own folders, and those of User2, User3, etc to which they have (e.g. read/list) access I followed the instructions on the wiki (for Version 1.X)- there are two concepts here: 1. Grant some [e.g. list/read] access on a mailbox folder to a particular user 2. Enable the acl_shared_dict to allow dovecot to track (and display to IMAP clients) the folders to which they have access. This will take the form of a BDB file: /var/lib/dovecot/shared-mailboxes.db This file can only be updated by using the SETACL command. *This is where I have the problem*. The SETACL command does nothing. No matter how hard I try, I cannot get dovecot to update this file. The only indication I have that the file exists and is readable by dovecot is the disappearance from the logs of the line: No acl_shared_dict setting - shared mailbox listing is disabled So I can see that dovecot knows the file is there because it does not complain any more. The file is there (because I created it myself, although it is empty: size = 0), and in a moment of weakness I made sure it could be updated (this will be changed back!): ls -l /var/lib/dovecot/shared-mailboxes.db -rwxrwxrwx 1 dovecot dovecot 0 2012-10-30 12:27 /var/lib/dovecot/shared-mailboxes.db But if I try to update the ACL, absolutely nothing happens: [ > command ] [ < reply ] > telnet localhost 143 < * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=CRAM-MD5] Email server > a login [User2] [pass] < a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH ACL RIGHTS=texk] Logged in > a SETACL Inbox [User 1] rl < a OK Setacl complete.

[Dovecot] Save/restore IMAP session state
by Timo Sirainen 30 Oct '12

30 Oct '12

Some future Dovecot version will have "imap-idle" processes where IDLEing IMAP connections get moved, so the system wouldn't waste so much memory for all the IDLEing imap processes. A week ago I thought I'd see how easy it would be to implement this. I got a basic proof of concept working as a "X-STATE" command. Save the state: a x-state * STATE AQDLW45QdwAAAAMAAABuAQAAAAAAAFAcffYAPHnpFctbjlDbYQAAcEmzCwAA a OK State exported. Restore the state: b x-state AQDLW45QdwAAAAMAAABuAQAAAAAAAFAcffYAPHnpFctbjlDbYQAAcEmzCwAA b OK State imported. This could also be used to implement quick session state restoring for webmails (as suggested by Michael Slusarz). For getting the imap-idle process there would have to be code that: * triggers the session saving when process is IDLEing * figures out what filesystem paths the imap-idle should be looking at (i.e. paths to selected mailbox's dovecot.index.log file and maybe for e.g. maildir new/) * send the session state string, paths and imap connection fd to imap-idle process via UNIX socket * implement the actual imap-idle process * implement a way for imap-idle process to send back the state and connection fd to restore the imap process The patch is ugly and still missing many things. Anyway I thought I'd include it here just in case someone was really eager to continue implementing it. :) I'm not sure when I'll have time for it. A full patch would probably have to have some session_save()/session_restore() functions in lib-storage API. But a quick and dirty way is possible to implement for v2.1 as well, as long as some IMAP extensions aren't used (most importantly rfc5267).

I did consider it, and you're right, it is tricky to get it absolutely right. If robusteness and security was of utmost importance, I would abandon PHP too.

[Dovecot] does dovecot interpret any mail headers specially with maildir?
by Christoph Anton Mitterer 30 Oct '12

30 Oct '12

Hi. For mbox, http://wiki2.dovecot.org/MailboxFormat/mbox#Dovecot.27s_Metadata lists a numer of mail headers: - X-IMAPbase - X-IMAP - X-UID - Status - X-Status - X-Keywords - Content-Length that are treated specially by dovecot. It also suggests, that these should be stripped by the LDA (I guess in order that someone sending you such mail cannot set the status or keywords, or even "attack you" by setting a bogus Content-Length). I wondered, when using maildir, are there any headers that dovecote would treat specially, too? And which I therefore should strip? Thanks, Chris.

[Dovecot] No failover from director to backend?
by Patrick Westenberg 29 Oct '12

29 Oct '12

Hi everyone, short version: Is there no built in failover mechanism for the director service to handle a backend failure? Long version: I have a frontend server running the director service and two backends. Due to maintenance I had to shut down one of the backends which caused connection errors for the users being directed to this backend. I was very surprised as I expected the director to redirect these users to the remaining backend. Am I wrong or is the director not working as expected?

[Dovecot] INBOX permissios woes
by Josep L. Guallar-Esteve 29 Oct '12

29 Oct '12

Hello, I have a dovecot system that uses winbind authentication against Active Directory. I set it up by following the directions in the wiki. That works great. When a new user receives an email, the inbox is created with permissions 600 (rw- --- --) and ownership user:mail , even though I did chmod 02770 /var/spool/mail. And then, when dovecot tries to access the inbox, it throws the error: Oct 29 13:47:59 imap-login: Info: Login: user=<user1>, method=PLAIN, rip=10.0.0.6, lip=10.0.0.26, mpid=29047, secured Oct 29 13:47:59 imap(user1): Error: stat(/var/mail/user1) failed: Permission denied Oct 29 13:47:59 imap(user1): Error: stat(/var/mail/user1) failed: Permission denied Accessing users' Sent, Trash, creating new folders.... all that works fine. I've been looking at the documentation, reading the wiki, searching on google, asking on IRC. If you have any hint or documentation that I've must have overlooked, please let me know.

[Dovecot] Overlapping userdb/passdbs
by James Devine 29 Oct '12

29 Oct '12

I have an ldap server for which each entry includes the email address and the username portion of the email address for authentication. Authentication works by username if the username is unique among all the entries. I need to now add some users which must authenticate even if the username is not unique. I figured one way to do this would be to add a second user/pass db which puts further restrictions on the ldap query to make it unique for those users. This doesn't seem to work however as if the user is found in the first ldap query but the password does not match it does not try the second. I would use the password as part of the query but this setup requires me to allow the client to hash the password. Is there a way to do this? Or maybe I am approaching the problem wrong.

[Dovecot] Can Dovecot authenticate against an external email server?
by Marc Perkel 29 Oct '12

29 Oct '12

Just wondering if anyone has done this. I have a spam filtering service where I am now storing spam for users I filter for. It's a filter and forward service so I don't control the recipient's email server. What I would like to do somehow is have the user enter their email address and password and then look up their POP/IMAP server from a database and try to authenticate from it. If sucessful then the user will be able to access their stored spam using Dovecot and Squirrelmail. Any suggestions? Thanks in advance

[Dovecot] Auth caching and password changes
by Angel L. Mateo 29 Oct '12

29 Oct '12

Hello, In my system I have configured auth caching. The problem I have is that whenever a user changes his password, he/she can't login to dovecot after a while and the scenarios described at http://wiki2.dovecot.org/Authentication/Caching are not applied. I have tried also with "doveadm auth cache flush <login>", but it didn't work. He also could to login again if he waits for a time or if I run "doveadm auth cache flush" in the server, flushing all auth information from cache. I have attached the log I had when I changed my password (and suffered the problem). I have attached my doveconf -n too. -- Angel L.

[Dovecot] trash plugin not doing it's job
