[Dovecot] How many concurrent IMAP sessions?
by Patrick Ben Koetter 01 Oct '09

01 Oct '09

Has anybody ever bothered to measure how many concurrent IMAP sessions dovecot can handle? I know it depends on hardware, filesystem, mailbox type etc., but what exactly controls the number and what have people on the list measured? p@rick -- state of mind Digitale Kommunikation http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht München Partnerschaftsregister PR 563

[Dovecot] deliver doesn't support !include directive, mail is bounced
by Christoph Berkemeier 30 Sep '09

30 Sep '09

Hello, dovecot deliver is used here as a LDA. When I add !include /usr/local/etc/$INCLUDE.FILE to my dovecot.conf I get this error in the maillog: relay=local, delay=0.04, delays=0.02/0/0/0.02, dsn=5.3.5, status=bounced (local configuration error. Command output: Fatal: Error in config file /usr/local/etc/dovecot.conf: deliver doesn't support !include directive /usr/local/etc/$INCLUDE.FILE contains: listen: $HOSTNAME ssl_cert_file: /etc/$FILE ssl_key_file: /etc/$FILE auth_krb5_keytab = /etc/$FILE It would be nice if this bug gets fixed or a comment add, that you can not use include, when you use deliver as your LDA.

[Dovecot] deliver: Fatal: setgid(114) failed with euid=8, gid=8, egid=8: Operation not permitted
by Fredriksson Turbo 30 Sep '09

30 Sep '09

I'm calling 'deliver' from Postfix and in some cases from Procmail. I set this system up more than six months ago and it's been working flawlessly until yesterday (16:52:19 local time) when it, without any apparent reason, just stopped delivering mails! Lots of checking and googling (I've forgot how exacly I setup the system :), I made 'deliver' SUID and it worked again... But it seems that all mails that was received between 16:52:19 and 11:07:52 (which was the last mail that couldn't be delivered) is lost! Is there any way to avoid mails being lost for reasons such as this? Is this a Postfix, Procmail or Dovecot thing? This system runs on a Ubuntu Intrepid: Postfix v2.5.5-1 Procmail v3.22-16ubuntu3 Dovecot v1:1.1.4-0ubuntu1.3 Thinking it over again (when double checking this mail), it might have been a automatic "de-SUID thingie or other" in Ubuntu. If memory serves me right, there used to be something like that in Debian long ago... But for whatever reason it DID happen, I'd appreciate an idea on how to avoid loosing mails if something happens to the delivery process...

[Dovecot] sieve & vacation - ignores "days" parameter
by Jacek Osiecki 30 Sep '09

30 Sep '09

Hi, I am going further with dovecot configuration. Finally managed to configure roundcube 0.3 with managesieve plugin. And it works, although... not perfectly :( For some issues probably roundcube-managesieve is guilty, but simply the sieve plugins seems to work wrong. Here is my sieve file: require ["vacation","fileinto"]; # rule:[wakacje] if anyof (true) { vacation :days 7 text: I am on vacation . ; } # rule:[silver-save] elsif allof (header :is "From" "joshua(a)hybrid.pl") { fileinto "myown"; stop; } And it seems, that sieve ignores ":days 7" parameter. Every time I send the email to this account, I receive the automatic answer. Maybe I misconfigured something? Where does vacation plugin store the information on emails that have already received the automatic answer? Best regards, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944 I don't want something I need.

[Dovecot] dbox: maildir migration
by Timo Sirainen 30 Sep '09

30 Sep '09

I'm trying to clean up the code for Dovecot v2.0 and I just keep coming back to the same thought: Is having the super-fast maildir -> single-dbox migration really actually a good idea? Some problems with it: 1. Makes the code more complex.. And I've already fixed many bugs related to that, maybe not all. 2. Having some mails in maildir format and others in dbox format isn't really good in long term. The super-fast migration was mainly meant to be used as a quick and easy way to start using dbox and then slowly convert maildir files to dbox files. 3. There's currently no way to actually convert the migrated maildir files to dbox format. And I'm not really sure how such a tool would even be used. "doveadm -u <username> dbox convert-old-maildir-files" run one user at a time?.. Maybe a better alternative would be to simply do a proper full migration to dbox format, a few users at a time so disk I/O wouldn't explode? dsync especially could be helpful here. convert plugin could be replaced with a dsync plugin and then a migration could be done with: 1. Run a "pre-migration" dsync for n users (not absolutely required, but a good idea to avoid login delays). 2. Enable dsync plugin for the users (or this could be enabled always). 3. Switch users to dbox format. 4. Run a "post-migration" dsync for the users. If any user logged in before the post-migration was finished, the dsync plugin would finish the migration for that user. 5. Goto 1 with another set of users, repeat until finished with all users.

[Dovecot] getmail and Dovecot LDA deliver
by spacejam 29 Sep '09

29 Sep '09

Hello, my first post in this list. Hope it's the right place.:-) I'm having a problem running getmail together with Dovecot LDA for virtual users. To achive this I let getmail run under the user that owns the virtual email accounts-root. The problem is that getmail is running under the user vmail and therefore the emails received will be put into vmail's mailbox. But the emails getmail collected are actually for a virtual Dovecot user which has its maildir in a subdirectory of vmails home. The settings for the virtual users seem to be okay: I can login on Dovecot with virtual user account and I can send emails to Postfix for the virtual user. Postfix correctly uses devlier with the name of the virtual user and so the emails are going to the correct directory. For me it seems that getmail always uses the username under which getmail is currently running. As this must be a local user, getmails always announces this local user to deliver and deliver therefore puts the emails into the wrong account. My question is: How do I let deliver know that it should use a virtual user? I tried with the -d agrument in my getmail rc File, but deliver never accepts the parameter -d (always says unknown parameter -d). I tried as well to let getmail or deliver to be run as root, but then the emails will be delivered to roots home, which is not the goal too... Does anyone know a way how I can set getmail to handle emails for a virtual account properly? Any hint is appreciated as it already costed me hours of try-and-error Regards tobi -- View this message in context: http://www.nabble.com/getmail-and-Dovecot-LDA-deliver-tp24896318p24896318.h… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Enabling security on POP3 and IMAP
by Richard Hobbs 29 Sep '09

29 Sep '09

Hello, Currently, on our new test server, I am offering IMAP on 143 and POP3 on 110. We would like to enable security on both of these protocols to attempt to eliminate the risk from an internal password-grabbing/content-grabbing attack. I presume this would mean enabling SSL, and a more securure authentication, right? Or are plain text passwords just sent over the SSL, and therefore perfectly secure? Also, what are the steps to enable security for these protocols on an already-configured server? Is it possible to offer encrypted and non-encrypted services simultaneously, so people have a choice of whether they want security or not? I know that's a bit weird, but for testing it would be useful. Finally, is there a way to monitor which users are connecting over the secure ports and which users are connecting over the non-secure ports? Thanks in advance!

[Dovecot] compressed IMAP traffic
by Leonardo Rodrigues 29 Sep '09

29 Sep '09

Simply (and maybe stupid) question ...... is there anything that can be easily used to automatically compress IMAP traffic between client and server ? I was thinking if the SSL/TLS code enables some kind of compression as well. the idea is to reduce IMAP traffic between server and clients and not using VPN-like solutions, the idea is just some IMAP4 standard client (compatible with SSL/TLS if that's the case) and nothing else. can something like that be done ? -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

[Dovecot] sieve vacation error
by Andre Rodier 28 Sep '09

28 Sep '09

Hello everybody, First, I want to thank the development team for the quality and the stability of dovecot. It's now running without problem since two years on my debian box. Next, I'd like you help me to solve the problem I have with vacation/sieve script. My configuration is debian lenny, with standard dovecot packages (1.0). I have setup the sieve plugin, using roundcube on another machine, and filter is working fine. fileinto is working, as well as forward and discard. However, vacation is not working at all, and I have no error message. The mails sent to the account marked as vacation are received, but the auto answer process is not working. Here the successful logs from the vacation reject script, that I temporary use: Sep 23 17:32:41 mail deliver(some.user): Loading modules from directory: /usr/lib/dovecot/modules/lda Sep 23 17:32:41 mail deliver(some.user): Module loaded: /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so Sep 23 17:32:41 mail deliver(some.user): maildir: data=/home//some.user/Maildir Sep 23 17:32:41 mail deliver(some.user): maildir: root=/home//some.user/Maildir, index=/home//some.user/Maildir, control=, inbox= Sep 23 17:32:41 mail deliver(some.user): cmusieve: Using sieve path: /home//some.user/sieve/dovecot.sieve Sep 23 17:32:41 mail deliver(some.user): cmusieve: Executing script /home//some.user/sieve/dovecot.sievec Sep 23 17:32:41 mail deliver(some.user): msgid=<72817c95458dbded987b82ec644f7dce(a)red2.co.uk>: rejectedReturn-Path: <andre.rodier(a)red2.co.uk> Here the headers of an email received, and supposed to be auto answered.

I cant see any dovecot file. I have temporary try to use 0777 for home/sieve/maildir folders, but no file is created at all. * Is it the same process used to forward, discard and finally vacation ? * I use virtual file for users on postfix, and I also have a LDAP server for authentication. Do I have something to configure on dovecot to be sure that vacation is working with this configuration ? * As you may have noticed above, mails are redirected to localhost users. ( c.f X-Original-To: some.user(a)red2.co.uk and Delivered-To: some.user@localhost ) Is this can affect the process ? ( Remember that forward and reject is working ). * Is there a way to debug the vacation process ? Thanks for your help. André Rodier.

[Dovecot] Proxying Performance vs imapproxy
by Dan Poltawski 28 Sep '09

28 Sep '09

Hi, I'm planning on a new mail infrastructure which constists of multiple 'frontends' running webmail & public access pop/imap, which would communicate over imap/pop to 'backend mail stores'. My original idea was to run dovecot on the backends, use a predition on the frontends to proxy imap/pop and also run imapproxy in front of webmail [squirrelmail]. I've since read about the dovecot proxying features and it seems to make sense to replace predition in that above scenario. I'm unclear about the benefits of the auth_cache and how it compares to the using imapproxy in front of webmail client? Does it make sense to have authcaching switched on in the proxy and not on the backend server? (Doesn't the authentication just have to happen on the backend server?) Are there any performance benefits to using a proxying server, or is it just for splitting mailstores? thanks for your work, Dan Poltawski

[Dovecot] Upgrading Dovecot on CentOS 4 from 0.99 to 1.x
by Josep L. Guallar-Esteve 28 Sep '09

28 Sep '09

(sorry for my previous message, I sent it by mistake before finishing it) Hello, We have a production mail server running dovecot 0.99 (dovecot-0.99.14-1.rf). We are getting several errors corrected in dovecot 1.x versions: * corrupted inboxes (garbage at beggining of mbox files), * corrupted index files (Error: Corrupted file index /home/jsmith/.imap/Drafts/.imap.index: Sequence 6 not found from binary tree (6 msgs says header)), * others (Error: fcntl() failed with mbox file /var/mail/jsmith: Resource deadlock avoided), etc. I'm planning to upgrade using the instructions found at dovecot's wiki. On http://atrpms.net/dist/el4/ it is offered in 3 different versions: * dovecot 1..0.15-1_73.el4 * dovecot 1.1.19-1_96.el4 * dovecot 1.2.5-0_100.el4 I have a separated test system, where I'll test upgrading from 0.99 to final selected version, to discover any possible gotchas found while upgrading. Two questions: 1. Which version is the recommended to upgrade? I'd like stability and as little problems as possible over anything else, as we have a simple set up. 2. What is the preferred upgrade method? straight upgrade? (099 -> rpm -Fvh dovecot-1.2 ? Or upgrading one release at a time? (0.99 > 1.0 > 1.1 ...) Thank you in advance for any recommendation.

[Dovecot] require SSL certs only for encrypted connections?
by Florin Andrei 28 Sep '09

28 Sep '09

# 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-14-server x86_64 Ubuntu 9.04 Here's the situation: I have several local clients (Thunderbird) which do not use TLS at all. It's plaintext completely, on port 143, because the connection is local and there are no unauthorized users on this network (it's a home network). I want to keep it that way to keep things simple. Tools / Account Settings / Server Settings: Use Secure Connection: Never Use Secure Authentication: unchecked Until now, this has worked very well. No problems so far. But now I am also setting up IMAPS for remote iPhone clients, with client/server certificates. This is how I generated the certs: http://impetus.us/~rjmooney/projects/misc/clientcertauth.html On the iPhone I uploaded the client.crt file (couldn't import client.p12 for some reason). For Dovecot I am using ca.crt, server.crt and server.key. ssl_listen: *:993 ssl_disable: no ssl_ca_file: /blah/ca.crt ssl_cert_file: /blah/server.crt ssl_key_file: /blah/server.key ssl_key_password: ssl_parameters_regenerate: 168 ssl_cipher_list: ALL:!LOW:!SSLv2 ssl_cert_username_field: commonName ssl_verify_client_cert: yes disable_plaintext_auth: no auth default: mechanisms: plain login ssl_require_client_cert: no ssl_username_from_cert: no I analyzed the connection on 993 with Wireshark and apparently all is good: it's encrypted, I see the certificate exchanges taking place. But I am worried about authenticating the connections from the iPhone and I would like to configure "ssl_require_client_cert: yes" so that a valid certificate is always required. But if I do that then Thunderbird fails to login because it's required a certificate. This is puzzling. I thought that setting would only influence SSL connections. But apparently it also affects plaintext logins from Thunderbird. Is there a way to require a cert from the iPhone TLS connections on port 993, but do not require it from clients connecting to port 143? -- Florin Andrei http://florin.myip.org/

[Dovecot] Segfault in quota-fs plugin
by Brandon Davidson 28 Sep '09

28 Sep '09

Hi all, We recently attempted to update our Dovecot installation to version 1.2.5. After doing so, we noticed a constant stream of crash messages in our log file: Sep 22 15:58:41 hostname dovecot: imap-login: Login: user=<USERNAME>, method=PLAIN, rip=X.X.X.X, lip=X.X.X.X, TLS Sep 22 15:58:41 hostname dovecot: dovecot: child 6339 (imap) killed with signal 11 (core dumps disabled) We rolled back to version 1.2.4, and installed 1.2.5 on a test system - something we'll have to make sure to do *before* rolling new versions into production. Anyway, after examining a few core files from the test system, it looks like the recent changes to the quota plugin (specifically the maildir backend's late initialization fix) have broken the other backends. Stack trace and further debugging are available here: http://uoregon.edu/~brandond/dovecot-1.2.5/bt.txt The relevant code seems to have been added in changeset 9380: http://hg.dovecot.org/dovecot-1.2/rev/fe063e0d7109 Specifically, quota.c line 447 does not check to see if the backend implements init_limits before calling it, resulting in a null function call for all backends that do not do so. Since this crash would appear to affect all quota backends other than maildir, it should be a pretty easy to reproduce. I've attached a patch which seems to fix the obvious code issue. I can't guarantee it's the correct fix since this is my first poke at the Dovecot source, but it seems to have stopped the crashing on our test host. Regards, -Brandon

[Dovecot] Running dovecot master processes across multiple IPs
by Steven F Siirila 28 Sep '09

28 Sep '09

We are running dovecot 1.1.8 and are currently running it with 4 master processes (one for each of the protocols: imap, imaps, pop3, pop3s). The idea was to spread out the load so as to not overwhelm any one master. This has worked well. To take it further, we're contemplating running masters across multiple IP addresses, where the host/service name DNS records would be something like this: imap-server.domain A 10.1.1.1 A 10.1.1.2 A 10.1.1.3 A 10.1.1.4 The default route would either be through the first address (10.1.1.1 in this example) or potentially across all of them in presumably a round-robin fashion. Do you see any problems with this? Has anyone done this? -- Steven F.

[Dovecot] Ubuntu 9.x segmentation fault with vpopmail auth
by Timothy Timmons 28 Sep '09

28 Sep '09

I've been trying for 24 hours now, to get an IMAP server which will autenticate off of vpopmail cdb database and the auth module always segfaults on login. I'm using vpopmail 5.5.0 only because it is the only version which seems to create a dynamically linked version of the library. I tried latest releases dovecot 1.0, 1.1, and 1.2. Also latest mercurial pulls of 1.1 and 1.2. Even old versions of courier-imap and courier-authlib do it, but with these I can try older versions of vpopmail cause they don't require the dynamically linked version of libvpopmail. So I'm thinking it is something with Ubuntu 9.04 and pretty much all third party vpopmail authentication code. Strangely qmail-pop3d works fine with vchkpwd, just I cannot find any IMAP server that will work no matter what combination of vpopmail and version of the IMAP server. If anyone can figure this out I'd greatly appreciate it.

[Dovecot] Sieve: problems installing in different prefix
by Andreas Ntaflos 28 Sep '09

28 Sep '09

Hi list, but mainly Stephan :) when building and subsequently installing the new Sieve plugin I am coming across a small difficulty when it comes to "make install". The libraries lib90_sieve_plugin.* always get installed in the directory /usr/local/lib/dovecot/lda, no matter what "prefix" argument is supplied to "make install". Only the libraries seem affected, not the rest of the Sieve plugin distribution (i.e. sieve, sievec, sieve-test, ...). Background: I like using XStow [1] to manage packages built from source. With XStow one can configure and build software like Dovecot and Sieve as usual (./configure && make) but then install it under a custom directory/prefix, like /usr/local/stow/dovecot-1.2.5. The "prefix" argument for "make install" is used for this, i.e.: make install prefix=/usr/local/stow/dovecot-1.2.5 XStow is then used to create symlinks to the correct places in the file system. For example the Dovecot binary gets installed in /usr/local/stow/dovecot-1.2.5/sbin/dovecot and a symbolic link is created by XStow: /usr/local/sbin/dovecot -> ../stow/dovecot-1.2.5/sbin/dovecot The advantages are clear: installing a software package is a matter of configuring, building and then installing under a custom directory, and letting XStow create symlinks. Updating is as easy as installing the new version in a parallel custom directory and letting XStow update the symlinks. Removing a software package just involves letting XStow remove the symlinks and doing an rm -rf on the custom directory. No more accidentally orphaned files or the need to keep the compiled source distribution around to be able to issue a "make uninstall". Back to the problem: The Sieve source distribution seems to have some hard-coded setting to always install the libraries under /usr/local/lib/dovecot/lda and not honouring the "prefix" argument for "make install". This is probably a libtool issue, but I am not sure. I know my way around the Autotools but here I am a bit lost. Looking at the generated Makefile in dovecot-1.2-sieve-0.1.12/src I can see the following: moduledir = /usr/local/lib/dovecot/ It *should* look like this: exec_prefix = ${prefix} ... moduledir = ${exec_prefix}/lib/dovecot/ This explains why the install prefix is not honoured here. The "moduledir" has already been hardcoded, instead of prefixed. For comparison look at the Dovecot source distribution. Here all libraries are installed correctly under the specified prefix. An example is src/lib-sql. The generated Makefile includes these lines, which are correctly honouring the prefix: exec_prefix = ${prefix} ... moduledir = ${exec_prefix}/lib/dovecot ... #sql_moduledir = $(moduledir)/sql AM_CPPFLAGS = \ -I$(top_srcdir)/src/lib \ -DMODULEDIR=\""$(moduledir)"\" \ $(SQL_CFLAGS) The last few lines seems to make sure that gcc uses the defined moduledir, but as usual generated code is not immediately comprehensible for the casual viewer :) The top-level generated Makefile also contains a correctly defined moduledir: moduledir = ${exec_prefix}/lib/dovecot So, which knobs have to be turned to have the Sieve source distribution use a correct "moduledir" and not a hardcoded path? I hope I could explain the problem correctly and haven't drawn any wrong conclusions here. I will continue to investigate this and maybe even provide a patch if I find a solution but it is probably easier for the maintainer and author of the build system to look at this and determine what to do. Anyway, apologies for this lengthy post. I hope it wasn't too long to read.

[Dovecot] Sieve: redirect and keep action, possible bug
by Andreas Ntaflos 27 Sep '09

27 Sep '09

Hi, Using Dovecot 1.2.4 and the new Sieve implementation in version 0.1.12, I ran into a problem that could indicate a bug in Sieve. The following is a simple script (as generated by Horde's Ingo application) to redirect incoming mail and also keep a copy of the message in the local inbox: if true { redirect "foo(a)example.org"; } if true { keep; stop; } Problem is, it doesn't work as expected: no copy of the message is kept in the local inbox. However, if I explicitly tell Sieve to "fileinto" it works fine: require ["fileinto"]; if true { redirect "foo(a)example.org"; } if true { fileinto "INBOX"; stop; } Is this a bug in Sieve or am I wrong about how "keep" works? Thanks in advance! Andreas -- Andreas Ntaflos Vienna, Austria GPG Fingerprint: 6234 2E8E 5C81 C6CB E5EC 7E65 397C E2A8 090C A9B4

[Dovecot] Dovecot + DRBD/GFS mailstore
by Guy 26 Sep '09

26 Sep '09

Hi guys, I'm looking at the possibility of running a pair of servers with Dovecot LDA/imap/pop3 using internal drives with DRBD and GFS (or other clustered FS) for the mail storage and ext3 for the root drive. I'm currently using maildrop for delivery and Dovecot imap/pop3 with the stores over NFS. I'm looking for better performance but still keeping the HA element I have now with shared storage over NFS. Has anyone had experience with a setup like the one I'm suggesting? What was performance like with Dovecot using GFS? Thanks Guy -- Don't just do something...sit there!

by AnneWilson 25 Sep '09

25 Sep '09

I have been using Dovecot for about three years, and am currently using version 1.0.7 under CentOS. One of my users can no longer access his Inbox, although he can read mail in other folders. After a fair bit of log-viewing and looking for clues it suddenly began to make a sort of sense. The error message in the logs is Error: IMAP(david): unlink(/home/david/Maildir/cur/cur:2,ST) failed: Is a directory Eventually I came to /home/david/Maildir/dovecot-uidlist and compared it with my own. The second line in the problem account file is 'cur:2,ST. I backed up the file, then deleted that line. Sure enough, I could then open the messages. Unfortunately, when I close KMail I saw the line 'cur:2,ST' added to the end of dovecot-uidlist, and of course I'm back with the error. Can someone please explain to me what is causing this, and how I can correct it? Thanks Anne

[Dovecot] Feature request: 'dovecot-shared' files to be configurable
by Hendrik Pahl 24 Sep '09

24 Sep '09

Hi list, using dovecot in a more complex environment nearly always requires use of ACLs and shared mailboxes/folders. Now, to make life more easy for the users, we can use 'dovecot-shared' files to eable per-user \seen-flagging. Is it possible to make this issue configurable in the dovecot config, something like "always keep a 'dovecot-shared' file in users maildir, even if that mailbox is not shared"? That would be nice, since creating that files by hand is really time-consuming. Or are there any relations which avoid making this issue configurable?

[Dovecot] Upgrading Dovecot on CentOS 4, from 0.99 to 1.x
by Josep L. Guallar-Esteve 24 Sep '09

24 Sep '09

Hello, We have a production mail server running dovecot 0.99 (dovecot-0.99.14-1.rf). We are getting several errors corrected in dovecot 1.x versions: * corrupted inboxes (garbage at beggining of mbox files), * corrupted index files (Error: Corrupted file index /home/jsmith/.imap/Drafts/.imap.index: Sequence 6 not found from binary tree (6 msgs says header)), * others (Error: fcntl() failed with mbox file /var/mail/jsmith: Resource deadlock avoided), etc. I'm planning to upgrade using the instructions found at dovecot's wiki. -- Josep L.

[Dovecot] Dovecot LDA, quota, sieve
by Jacek Osiecki 24 Sep '09

24 Sep '09

Hi, While moving services to a new server, I finally decided to switch from exim + procmail delivery to exim + dovecot-LDA (dovecot 1.2.5). All accounts are virtual - their settings are stored in mysql. This also includes configuring Quota and Sieve. So... there come some doubts: 1. Using "deliver" As I see, deliver uses auth-master socket to retrieve the mailbox settings (especially mailbox location). So, enabling dovecot-auth socket is everything I need to enable dovecot-LDA (apart from the exim configuration, which is explained quite clearly in wiki)? 2. Autocreation of mail folders Is it possible somehow to automatically create folders (like Trash, Sent-mail etc.)? 3. quota and its dict file. map { pattern = priv/quota/storage table = popbox username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } First - what is the "username_field" here? I'm running multiple domains, so will it be just username@domain? And - if so - is it possible to use the existing tables? I mean, that in my configuration I have a table named "popbox" with fields "local_part", "domain_name" and "quota". It would be perfect to make use of it, but either I could not find the solution or it simply requires an extra table... Hope someone will be able to help :) Best regards, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944 I don't want something I need. I want something I want.

[Dovecot] windows imap clients
by Charles Sprickman 24 Sep '09

24 Sep '09

All, This is slightly OT, but I figure a bunch of folks running IMAP servers should have some strong opinions on the topic. While working on a migration to Dovecot, I had the opportunity to move one account to a server running same. This is an in-house billing department box that 3-4 people share. In theory, this should work well - all the billing folks see the same email, save sent mail to the same place, have the same set of folders available, and concurrent access is no problem. In practice, I'm finding most clients kind of suck. They started with Outlook, and that did not work well. The list of problems is long. They've been using Thunderbird for some time and I'm finding the following issues there: -searches across 2GB+ of mail are painfully slow, since it's all server-side -while the inbox is checked regularly and automatically, other folders are not unless the user manually checks them. getting tbird to do this involves a fairly non-intuitive process, and there's also the issue of making sure everyone actually adds the folders they need to watch -the client does not deal well with large amounts of mail in general - some operations give no feedback, like expanding large sub-folders or doing large copy/move operations. this leads to the user quitting the app and starting the whole process again. dovecot deals with this more gracefully than the old server (Courier), but it's still an issue -offline operation would be handy sometimes, but tbird has no "hybrid" mode, and again, one must select every folder for offline access As much as people like to bash it, OS-X mail.app is basically what I'm looking for. It addresses all the shortcomings in Tbird. If I tell it to make messages available offline, it does that for all boxes. It always checks all my boxes, and when a search is performed it searches on the local copy rather than the server (which is quite polite, IMHO). It works quite well with no internet connection as well. I have about 50,000 messages in it now across 5 accounts and it only rarely gets laggy on me. I want this client on Windows, basically. :) I'm installing Mulberry now, but the manual seems to indicate it also will rely on the server-side search unless it's in offline mode (which has to be toggled - not a good solution). I must say, Dovecot has impressed the hell out of me. I had a chance to deal with the same mailbox in courier and dovecot, and everything is much faster, especially in mail.app and roundcube. Insanely fast... What else is out there for windows clients? Thanks, Charles ___ Charles Sprickman NetEng/SysAdmin Bway.net - New York's Best Internet - www.bway.net spork(a)bway.net - 212.655.9344

[Dovecot] Solr Plugin make only INBOX able to search
by rui.carneiro＠portugalmail.net 23 Sep '09

23 Sep '09

Hi all, I have downloaded and installed dovecot 1.2.4 with Solr plugin. After that, when I try to do some searches the results are weird. All messages that aren't on INBOX folder are ignored. For example, if I have a folder named "Test Folder", when I try to do ". search text <string>" the result is always empty. I tried TEXT, SUBJECT and BODY arguments and none of them returned any email. Any idea of the problem's source? Regards, Rui Carneiro

[Dovecot] SharedMailboxes in a distributed environment
by Christian Rohmann 23 Sep '09

23 Sep '09

Hello folks, I'd like your thoughts on the following problem: If one is using v1.2+ IMAP ACLs to allow users to share their mailbox and uses SQL as dictionary backend, every dovecot server would know which ACLs to enforce. But as the wiki states here "http://wiki.dovecot.org/SharedMailboxes/Shared" dovecot needs access to the other mailbox. Does that automatically mean that one dovecot machine needs to have filesystem access to the all mailboxes that are to be shared? Is there no way to share mailboxes (folders) between different servers? (apart from using NFS i.e.) -- Christian Rohmann Content Delivery Server u.

[Dovecot] shared/public mailbox doesn't exist
by Eric Shubert 22 Sep '09

22 Sep '09

I have 3 servers running dovecot 1.0.10. 2 of them are configured with a shared/public namespace, but I'm having trouble getting it to work on the third, even with 2 working examples to go by. There's something I'm missing, and I'm hoping that someone here can see/tell what it is. I've created the maildir for sharing: # cd /home/vpopmail/domains/mydomain.com # maildirmake shared # chown -R vpopmail:vchkpw shared Then added the configuration to dovecot.conf: # shared namespace namespace shared { separator = . prefix = shared. location = maildir:/home/vpopmail/domains/mydomain.com/shared } Restarted dovecot: # service dovecot restart When I try to subscribe to the shared namespace though with Outlook, I get: "Failed to subscribe the folder. Server responded: 'Mailbox doesn't exist: shared'." When I try to subscribe with Squirrelmail I get: "ERROR: Could not complete request. Query: SUBSCRIBE "shared" Reason Given: [TRYCREATE] Mailbox doesn't exist: shared" I've tried various combinations of permissions to no avail. Suggestions welcome. I'm at my wits end. -- -Eric 'shubes'

[Dovecot] Dovecot versions and index compatibility
by Steven F Siirila 22 Sep '09

22 Sep '09

I realize these are older versions, but I'd like to know specifically whether dovecot 1.1.6 and dovecot 1.1.8 are compatible index-wise. In particular, if we downgraded from 1.1.8 to 1.1.6 would there be any issues with doing so? I realize there are later versions, but we've tested both of the above extensively, but recently loaded up a server with 1.1.8 and found that the 'imap' process core dumps frequently, so before we pursue later versions we thought it would be best to downgrade to 1.1.6. -- Steven F.

[Dovecot] Managesieve displays folder name (dovecot/sieve)
by Seba 21 Sep '09

21 Sep '09

Hi, I'm using Dovecot 1.2.4 with ManageSieve 0.11.9 and Sieve. All works fine but users can subscribe to the folder "dovecot/sieve" which is also displayed in the folders list. protocols = imap managesieve protocol managesieve { listen = ip_address:2000 managesieve_logout_format = bytes ( in=%i : out=%o ) } plugin { sieve=~/Maildir/.dovecot.sieve sieve_dir=/home/vmail/%d/%n/Maildir } In the maildir of the user I see this folders and files: .Drafts/ .Sent cur/ new/ temp/ sieve/ @.dovecot.sieve ingo.sieve The file "ingo.sieve" comes from Horde Ingo because users manage their scripts with ingo.The symlink "dovecot.sieve" is correct and point to ingo.sieve. When users browse their available IMAP folders they'll see a folder "dovecot/sieve". Can this be turned off or restricted with acl's? Without an symlink all folders are displayed normally without the "dovecot sieve" folder. Thanks.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm little confused with the way dovecot (1.2.4) is reporting quota. with this config protocols: imaps ssl: required ssl_ca_file: /root/cert/CA_Bundle_Trans.crt ssl_cert_file: /root/cert/mails.crt ssl_key_file: /root/cert/mails-key.pem.rsa disable_plaintext_auth: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: maildir:%h/Maildir mail_debug: yes mail_plugins: quota imap_quota lda: postmaster_address: postmaster(a)example.com mail_plugins: quota cmusieve mail_plugin_dir: /usr/lib/dovecot/lda auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd plugin: quota: maildir:User quota quota_rule: ?:storage=20G sieve: ~/.dovecot.sieve everything works fine. TB says, there 20G quota. Command echo "1 GETQUOTAROOT INBOX" | USER=foo dovecot --exec-mail imap reports * QUOTAROOT "INBOX" "User quota" * QUOTA "User quota" (STORAGE 0 20971520) 1 OK Getquotaroot completed. Now I change the first line in foo's maildirsize file to "0S" to allow unlimited quota. Then I boost it's size to force recalculation (just to be sure) dd if=/dev/zero bs=1k count=6 >> ~foo/Maildir/maildirsize - From now, TB still reports 20GB quota for user foo, the above "echo" command still reports 20971520, but(!), quota is actually unlimited for user foo. OK, now I stop dovecot, delete maildirsize, change line in dovecot.conf quota_rule = ?:storage=0 and start dovecot again. The same result - TB still reports 20GB quota for user foo, the above "echo" command still reports 20971520, but(!), quota is actually unlimited for anyone. When I set some limit in ~foo/Maildir/maildirsize now, same values 20971520) are reported, although the limit works! Looks like LDA (deliver) works fine, but imap_quota plugin is doing something weird. Finally, the question ;-) Where does that value (20971520) come from? Is it a feature or a bug? - -- David Kmoch -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkqfhQoACgkQsUUM+N2AWobj7ACgh3yCU9LVfe1Pp2lO0nBG9iKf zbgAn15UvkVM0AeCxaUlDeYgFu++8TOn =CAoG -----END PGP SIGNATURE-----

[Dovecot] plugin development guide for non-FS backing store
by Chang Song 21 Sep '09

21 Sep '09

Hi, folks. I was wondering if anyone has some sort of guide or reference on plugin development. We are trying to develop a non-filesystem backing store. So basically we do not store mailboxes for users in local filesystem. We do RPC call to fetch from fileservers. Thank you in advance. Chang

[Dovecot] Override quota rules based on mail's content
by Andreas Calvo Gómez 21 Sep '09

21 Sep '09

Hi, I've a mail server with Postfix and Dovecot, using a LDAP backend to get the users. I've also configure quota rules, and I'm able to get the quota from LDAP. But I need the mails that come from the local domain to bypass the quota rule and be delivered to the users' inbox. Is there any way to do that? Information required by Dovecot's mailing list rules: +++ dovecot.conf +++ # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-15-server x86_64 Ubuntu 9.04 ext4 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_user: postfix valid_chroot_dirs: /var/spool/dovecot first_valid_uid: 1000 first_valid_gid: 512 mail_privileged_group: mail mail_location: maildir:/var/spool/dovecot/%n/ mail_plugins: quota imap_quota imap_client_workarounds: delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep auth default: mechanisms: plain login default_realm: esci.es username_format: %Lu passdb: driver: pam passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: prefetch userdb: driver: passwd userdb: driver: ldap args: /etc/dovecot/dovecot-ldap-userdb.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: mail group: mail plugin: quota: maildir:User quota quota_rule: *:storage=50M quota_rule2: Trash:ignore +++ dovecot-ldap.conf +++ hosts = ldap.esci.es auth_bind = yes ldap_version = 3 base = ou=Users, dc=esci, dc=es scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mailQuota=quota_rule=*:storage=%$M user_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%u)(uid=%n))) pass_attrs = uid=user,userPassword=password,\ homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid,mailQuota=userdb_quota_rule=*:storage=%$M pass_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%u))) default_pass_scheme = SSHA Thanks. --------------------- Andreas Calvo Gómez <andreas.calvo(a)admi.esci.es> Dept.

[Dovecot] Automatic fd limit changing
by Timo Sirainen 21 Sep '09

21 Sep '09

I just realized that Dovecot should probably be doing something different with how it handles fd limits. The way it currently works is: 1. It checks some settings and warns at startup if fd limit is lower than what master process might need. 2. For login processes it calculates how many fds are needed and then either increases or decreases it. So it's automatically and silently increasing fd limit for some processes, but not for others. Should it just automatically increase the limits to all processes when necessary, or never increase and just warn that the limit is too low?

[Dovecot] Sieve not fast enough after upgrade?
by Nikolay Shopik 21 Sep '09

21 Sep '09

I've upgraded mine Dovecot 1.0.15 to 1.2.4 also moved to new Sieve. I have simple sieve rule: if header :contains "Delivered-To" ["bcc(a)bcc.inblock.ru"] { setflag "\\Seen"; } It basically mark my own messages which are saved to Sent folder. When I was on 1.0.15 I never seen unread count in Thunderbird, but suddenly after upgrade I seen unread message in Sent folder just after I've sent message. If I open Sent folder it already marked as read. Me wonder if this is actually Dovecot much faster delivers and reports to MUA there is new unread message or Sieve not perform fast enough?

[Dovecot] Dovecot Sieve Vacation Messages
by Steven Murphy 20 Sep '09

20 Sep '09

I'm using a Postfix, Dovecot, MySQL setup with virtual domains. I have mail being delivered through Dovecot LDA working 100%. I'm trying to use sieve to handle vacation messages but dovecot is not reading the .dovecot.sieve file in the users maildir. I have a hunch it has to do with my dovecot-sql query but have had no success with what I found in the forums from Googling. Any help would be greatly appreciated.

[Dovecot] simple feature request: IMAP logged out message
by Leonardo Rodrigues 18 Sep '09

18 Sep '09

i'd like to make a simple feature request on dovecot .... i'm using v1.2.4 (latest one) and IMAP logout message, by default is: Sep 18 14:26:27 correio dovecot: IMAP(user(a)domain.com): Disconnected: Logged out bytes=384/932222 the message can be a little customized with: # IMAP logout format string: # %i - total number of bytes read from client # %o - total number of bytes sent to client imap_logout_format = bytes=%i/%o The remote IP address, the IP which the user is coming from, can only be seen on the login message: Sep 14 09:09:12 correio dovecot: imap-login: Login: user=<user(a)domain.com>, method=PLAIN, rip=187.6.xx.xx, lip=200.140.yy.yy the feature request is that the remote IP address could be added on the Logout message too, that would make much easier to watch connections from some specific user and from some specific ip address, regarding traffic of the connection. For example, something like: Sep 18 14:26:27 correio dovecot: IMAP(user(a)domain.com): Disconnected: Logged out bytes=384/932222, rip=187.6.xx.xx, lip=200.140.yy.yy -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it
