[Dovecot] dovecotadm error

07 Sep '12

When I use the following command: doveadm expunge -A mailbox Junk savedbefore 28d I get: doveadm(root): Error: User listing returned failure In the mail log file it says: dovecot: auth-worker(18549): Error: sql: Iterate query failed: Table 'system.users' doesn't exist (using built-in default iterate_query: SELECT username, domain FROM users) However this is setup: dovecot-sql.conf: iterate_query = SELECT username AS user FROM accounts though I have had to comment the following from dovecot.conf: #iteratedb { # args = /usr/local/etc/dovecot/dovecot-sql.conf # driver = sql #} because it errors on dovecot start up. I have already spent a bit of time on the Dovecot website and Google trying to find an answer. I want to get the expires plugin working.

[Dovecot] different userdb and/or passdb for lmtp and pop3/imap?
by Gábor Lénárt 06 Sep '12

06 Sep '12

Dear All, I have a bit complex question about ldap based user/passdb with some twists caused by the LDAP schema I have to use. It's complex for me at least, since it's my first time to try to setup any dovecot install which is more than a "trivial" thing eg for some unix system users. What I'd like to do: Users are stored in LDAP with the following schema: storageMailUid: contains user's uid in x@z format, and it CAN be different than mail address. This value is used to login (pop3/imap) and to get the maildir path (well, home) in the form of /mailstorage/z/x/ regardless of the value of the "mail" attribute. If @z part is missing (I mean the user supplied login, not the LDAP!), some default value (example.com) should be treated (I guess that's easy: auth_default_realm may be enough, isn't it). It is NOT possible to login via pop3/imap with mail, only with storageMailUid! This storageMailUid can specify a string which is not even an existing mail address, of course. mail: contains user's mail address, or even mail addresses (there can be more mail addresses - more mail ldap attributes - for a single ldap entry). This attribute cannot be used for pop3/imap login, neither it counts to resolve the maildir path, it only counts when a mail is received: the location of the user's maildir must be got from storageMailUid. storageMailQuota: it contains the quota value (in bytes) for the given user, which should be enforced on receiving mail, or by using IMAP (not counting the Trash folder which is a fixed size for all users and it must be handled outside of this). All user maildirs have the same fixed unix UID/GID, which is not stored in LDAP, but must be configured statically. "Home directory" of the user is also not stored in LDAP, it must be got from storageMailUid LDAP parameter. Mails are received via LMTP only. I'd like to use prefetchdb to minimalize the amount of LDAP lookups (however I can live without that). I am unsure if auth_bind is OK, or it should not be used, currently I'd like to play with auth_bind, since it worked before on other servers well. I'm totally lost with the user_attrs/pass_attrs to create this kind of configuration. In case of static userdb, it was easy to set up: passdb { args = /etc/dovecot/dovecot-ldap-passdb.conf driver = ldap } userdb { args = uid=vmail gid=vmail home=/mailstorage/%Ld/%Ln driver = static } With this, pop3/imap worked (quota was not of the scope yet, though), however lmtp is not ("passdb doesn't support lookups, can't verify user's existence" which is odd for me, as userdb does not support it in my opinion). Please, give some suggestion how to set up userdb and passdb to support this configuration which works with the described scenario. I should also set iterate_filter and iterate_attrs I guess, so some doveadm commands can work then (-A stuffs, I guess). I am also not sure if auth service should be used or not (I mean extra configuration related): since I want LMTP not LDA, I guessed I don't need it, but I am not sure. I am also confused, because on receiving a mail (via LMTP) different kind of LDAP lookup is needed: then mail must be searched, but it's storageMailUid based lookup in case of pop3 or imap login ... Is it possible to give different userdb/passdb for lmtp and pop3/imap? In theory it's even possible to have x(a)example.com as mail and y(a)example.com as storageMailUid for one user, and the opposite for the another, so lookups cannot be done together for mail and storageMailUid. The LDAP schema/rest of the system works this way, not an option to change. Any help is greatly welcomed. Thanks a lot in advance, Gábor

[Dovecot] managesieve problem
by Léon Keijser 06 Sep '12

06 Sep '12

Hi, I'm using roundcube in combination with postfix (2.6.6), dovecot (2.0.9) and pigeonhole (2.0.9). All works well except sieve. I've already posted on the roundcube forum (http://www.roundcubeforum.net/index.php/topic,9690.0.html ) but was told I should ask here since it's more likely a dovecot issue rather than roundcube. The problem is that if I want to manage sieve filters from roundcube, I get this error in maillog: Sep 5 12:55:39 emperor dovecot: managesieve-login: Login: user=<leon(a)EXAMPLE.COM>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=1575, secured Sep 5 12:55:39 emperor dovecot: managesieve(leon(a)EXAMPLE.COM): Error: sieve-storage: stat((null)) failed: Bad address Sep 5 12:55:39 emperor dovecot: managesieve(leon(a)EXAMPLE.COM): Error: sieve-storage: stat((null)) failed: Bad address Sep 5 12:55:39 emperor dovecot: managesieve(leon(a)EXAMPLE.COM): Fatal: Failed to open Sieve storage The managesieve daemon is listening though: emperor ~ # netstat -tlpne | grep dovecot tcp 0 0 0.0.0.0:143 0.0.0.0:* LISTEN 0 1275042 362/dovecot tcp 0 0 0.0.0.0:2000 0.0.0.0:* LISTEN 0 1275037 362/dovecot tcp 0 0 0.0.0.0:4190 0.0.0.0:* LISTEN 0 1275035 362/dovecot tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN 0 1275044 362/dovecot tcp 0 0 :::143 :::* LISTEN 0 1275043 362/dovecot tcp 0 0 :::2000 :::* LISTEN 0 1275038 362/dovecot tcp 0 0 :::4190 :::* LISTEN 0 1275036 362/dovecot tcp 0 0 :::993 :::* LISTEN 0 1275045 362/dovecot emperor ~ # telnet localhost 4190 Trying 127.0.0.1...

[Dovecot] dovecot stats: useful data to gather
by Patrick Ben Koetter 06 Sep '12

06 Sep '12

Timo, following our discussion on dovecot stats at the LinuxTag 2012 my team and I sat down and put together a list of stat items we think to be useful in daily dovecot usage. Besides pulling together all the data we also think it would be useful to have an SNMP interface to access the stats. Our offer to create and contribute a standalone web interface for dovecot stats stands. Here are the stats we believe to be useful: Login/Logout - total number login success/time - total number login failure/time - total number per authentication mechanism - total number plain sessions - total number STARTTLS sessions - total number of currently connected users (pop3/pop3s/imap/imaps/managesieve) - login names of connected users (not really stats, but great for actions regarding those uses e.g. force logout) - total number logout commands/time - total number BYE responses (autologout) Mailbox state - Inflow rate (number incoming messages/time) - Deleted rate (number \Deleted flagged messages/time) - Expunge rate (number Expunge operations/time) - total number current messages mailboxes normal storage - total number current messages mailboxes alt storage - total number read messages mailboxes normal storage - total number read messages mailboxes alt storage - per user number current messages mailboxes normal storage - per user number current messages mailboxes alt storage - per user number read messages mailboxes normal storage - per user number read messages mailboxes alt storage Mailbox Quota - total number persons under soft-quota per quota - total number persons above or equal soft-quota per quota - total number persons above or equal hard-quota per quota Performance - minimum time to write a message - maximum time to write a message - average time to write a message - minimum time to modify a message - maximum time to modify a message - average time to modify a message - minimum time to delete a message - maximum time to delete a message - average time to delete a message - minimum time search operations - maximum time search operations - average time search operations Regards, p@rick -- state of mind () 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

I frequently see the above log messages when the client and the server get their security protocol (SSL/TLS) and ports crossed up (i.e. trying IMAP/SSL on port 143 or trying IMAP/TLS on port 993). Try fiddling with TB's setting here and see if anything shakes loose. You can also use openssl and simulate the server end and maybe that will shed light on the situation: (You'll have to read the man page yourself to find all the options) openssl s_server -accept 993 ...

You could work out a cron job that does a "doveadm search ...", then diff it with one generated 24 hours ago, extract the common GID/UUIDs, then do a second pass to delete them. Not elegant, but it would probably work. (I just read the man page, and there doesn't seem to be an option to pipe the search like "doveadm search ... | doveadm expunge ...". You'll have to expunge one message at a time. Ugh.) Or maybe the advice "don't worry, be happy" applies here. I find that too many "mistake mitigation" features is counterproductive as users habitually relying on them, rather than being careful. Extending your grace period to a week will lessen the probability of this race condition. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Custom auth process in dovecot 2
by Richard Platel 04 Sep '12

04 Sep '12

Hi, I'm trying to upgrade from dovecot-1.1.x to 2.1.7. We have our own custom auth server process (because we want to do our own password validation and for other reasons) that listens on a UNIX domain socket and speaks the dovecot auth protocol. In dovecot 1.1 we could configure this with auth external { socket connect { master { path = /var/run/dovecot/auth.sock } } } as per http://wiki.dovecot.org/MainConfig I haven't been able to figure out how to do this in 2.1.7, is it possible?

[Dovecot] finding messages deleted before timespec
by Sven Hartge 04 Sep '12

04 Sep '12

Hi! I've been pondering about doveadm-search-query(7) and trying to formulate a search query for some time now and it seems there is no way to search for messages, which have been marked DELETED before a certain time. I want to use this to expunge all DELETED messages which have been in that state for 24h or longer. For example a cronjob runs at midnight to expunge those messages but a user deletes one just 10 minutes before that, this message should not be deleted until the day after. This is my first time diving deeper into IMAP search queries so I have the nagging feeling I am missing something important here. Grüße, Sven. -- Sigmentation fault. Core dumped.

This is the first part for Mozilla Thunderbird setup. I've seen this work both on Win32 systems and linux systems (mainly Linux Mint). There's a part on pop3/smtp. I am sure you can skip that and do your own magic for those two protocols : Pre-Installation, Wizard Configuration -------------------------------------- During initial Thunderbird startup, the admin is greeted by a welcome window named “Mail Account Setup” Click on Cancel Installation ------------ Click on “Edit” -> “Account Settings” New window pops up Click on “Add” New window pops up Fill in “Description” (e.g. “Name Surname mailbox”) On “Server Name” enter the IP address (e.g. 192.168.3.5) On “Port” enter the SMTP port (e.g. 25) On “Security and Authentication” → “Connection Security” enter none On “Authentication Method” choose Password transmitted insecurely On “Username” enter the users' username including the FQDN (e.g. name(a)domain.gr) Click on OK From “Edit”, click on “Account Settings” From “Account Actions” click on “Add Mail Account” New windows pops up Enter in the same name for “Your name” Enter in the same e-mail address for “Email address” On “Password” enter in users' password Click on “Continue” then without waiting click on “Manual Config” Once “Manual Config” is clicked, thunderbird will allow the admin to perform additional configuration tasks For “Incoming” the admin will choose “IMAP”, Server Hostname will be set to the servers' IP address (again, 192.168.3.5) From “Port” choose “993” From “SSL” choose “SSL/TLS” From “Authentication” choose “Autodetect” For “Outgoing” the admin will let the “SMTP” option For “Server Hostname”, choose the same IP address (e.g. 192.168.3.5) For “Port” choose “25” For “SSL” choose “None” For “Authentication” choose “Normal Password” On the Username field, enter the full user name, e.g. “user(a)domain.xn--gr-02t Click on “Re-test” Click on “Create Account” Check on the “I understand the Risks” checkbox Click on “Create Account” Click on “Confirm Security Exception” Click on “OK” Hope this helps and best regards, Spyros ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

[Dovecot] dovecot-antispam and Thunderbird, Outlook, etc.

Hi, In the documentation of dovecot-antispam it is mentioned that moving mails out of the spam folders trains them as non-spam. I.e. thunderbird automatically deletes old spam messages (after a time limit, i.e. 14 days). Will this also train the old spam messages as non-spam? Cheers, Eddy

I want to offer 'plain' unsecure pop/imap access, just for temp. testing purpose, do I simply comment out ssl = required ? Voytek -- Swyped on Motrix with K-9 Mail. Please excuse my brevity.

[Dovecot] Imap Ghost folder
by Sascha Zucca 03 Sep '12

03 Sep '12

Hi list, i have a strange "ghost" folder in my subscription list and just can't find out how to get rid of it. It seems to be someones Inbox, but it doesn't tell me whose. Here's a screenshot of Open-Xchanges Web-GUI: /http://s9.postimage.org/6aohh97ov/iehadjhb.jpg / As you can see there is an unamed folder just under Freigaben (Shares). In Thunderbird: /http://s12.postimage.org/z0n82k2u5/bjddgefg.jpg/ Now the Folder is "INBOX"...But it is noones Inbox, as the corresponding user (amazon e.g.) should be a prefix-folder right before the share. some output over Telnet: 1 lsub "" "*" * LSUB () "/" "INBOX" * LSUB () "/" "INBOX/Amazon" * LSUB () "/" "INBOX/Bestellung" * LSUB () "/" "Drafts" * LSUB () "/" "Sent Items" * LSUB () "/" "Spam" * LSUB () "/" "Trash" * LSUB () "/" "Freigaben/amazon/INBOX" 1 OK Lsub completed. 1 list "" "*" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "Sent Items" * LIST (\HasChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "INBOX/Amazon" * LIST (\HasNoChildren) "/" "INBOX/Bestellung" * LIST (\HasNoChildren) "/" "Spam" * LIST (\HasNoChildren) "/" "Drafts" * LIST (\Noselect \HasChildren) "/" "Freigaben/amazon" * LIST (\Noselect \HasNoChildren) "/" "Freigaben/" * LIST (\HasNoChildren) "/" "Freigaben/amazon/INBOX" 1 OK List completed. This looks a bit strange to me: * LIST (\Noselect \HasNoChildren) "/" "Freigaben/" But i don't know really if that is the ghostfolder. finally here's the interesting part in my dovecot.conf: / namespace private { separator = / prefix = #location defaults to mail_location. inbox = yes } namespace shared { separator = / prefix = Freigaben/%%n/ location = maildir:/var/mail/vhosts/%%d/%%n/:INDEX=/var/mail/vhosts/%%d/%%n/ subscriptions = no list = children inbox = no } / Any idea how to banish the ghost in the machine?

[Dovecot] exclude a folder for lazy expunge (move to trash)
by Angel L. Mateo 03 Sep '12

03 Sep '12

Hello, I'm configuring lazy expunge plugin to act as a kind of backup of my user's emails. I'm getting a little problem because a lot of my users use "move to trash" behaviour in their email client (most of them are using thunderbird which has no option to hide deleted messages and is a hassle working with mark as deleted with it). The problem combining move to trash with lazy expunge is that messages are stored in the expunge namespace twice, first when it was deleted from the original folder and the second when is deleted from the trash. So... is there any way to exclude trash folder from lazy expunge plugin, so mails are stored in the expunge namespace only when they are deleted from their original folder and not from the trash? Another idea... We are purging trash folders with a cron running "doveadm purge" commands. Is there any way to run this command disabling lazy expunge plugin? Any other idea not to duplicate these emails? -- Angel L.

[Dovecot] [Postfix] SASL Auth. using Dovecot with password forwarding proxy configuration
by Adi Pircalabu 03 Sep '12

03 Sep '12

Hi, I'm relatively new to Dovecot and I did a bit of search but couldn't find a possible solution for the particular setup I'm working on. Basically I have an SMTP/POP/IMAP proxy setup running Postfix & Dovecot. IMAP/POP authentication is done using the password proxy feature, where the login credentials are passed to the backend server after a db lookup, which does the actual authentication. The POP/IMAP part is working fine. What I'm trying to do is to use Dovecot SASL implementation in Postfix to do SMTP authentication in a similar manner. The problem I have with my current configuration is that SMTP authentication succeeds if only the username matches, because password forwarding works if the authentication succeeds with any given password, as documented at http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy My question is, given the above: is there a way to get SMTP authentication properly in this scenario? The way I see it now, Dovecot SASL accepting the login if only the user matches isn't quite "complete", the auth process should go further and authenticate against the backend server, same as for POP/IMAP connections. Does this requirement make any sense? Maybe I'm missing something in Dovecot configuration to get the SMTP authentication work in password forwarding mode, few pointers will be highly appreciated. PopBSMTP is not an sensible alternative in my case. Here's my configuration, plus some dovecot auth_debug log entries. As you can see, SMTP authentication succeeds with any given password. ---Dovecot--- dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.2.1.el6.centos.plus.x86_64 x86_64 CentOS

[Dovecot] Special Folder Mocking
by Eddy Ilg|univation 02 Sep '12

02 Sep '12

Dear Dovecot List, probably everyone knows the problem that different clients use different names for "Sent", "Trash" and so on. A simple question: Isn't it possible to advertise one imap folder with different names, depending on the client? E.g. if the client is Outlook, show the "Sent" folder as "Sent Elements" (translated from german) and if the client is Thunderbird, show the "Sent" folder as "Sent"? Best regards, Eddy Ilg

[Dovecot] New log entries with 2.0.19?
by Knute Johnson 02 Sep '12

02 Sep '12

I just upgraded my Ubuntu server from 11.10 to 12.04.1 and that upgraded Dovecot to 2.0.19. For some reason I'm getting a lot more (5 times) disconnect in IDLE and inactivity time outs. I'm using only IMAP with two users. Both users access the server from multiple devices, phone, tablet and desktop computer. I had previously set the max_userip_connections to 20 and rarely got the following limits exceeded message. That's probably being triggered when we are both home and using all of our devices on the same network. I've now changed it to 40 and we'll see how that does. The other is the IDLE and inactivity timeouts. I don't really understand how IDLE works and I couldn't find an inactivity timeout setting to play with. There are at this second 32 imap or imap-login processes running with only two phones and one desktop running. That's a few more than before the upgrade but not a lot. --------------------- Dovecot Begin ------------------------ Dovecot limits exceeded: max_userip_connections: penny from 216.240.58.138 to 216.240.58.140: 56 Time(s) Dovecot disconnects: Disconnected in IDLE: 485 Time(s) Inactivity: 343 Time(s) no auth attempts: 14 Time(s) no reason: 21 Time(s) Everything seems to be working OK so maybe I should just not worry about it?

Re: [Dovecot] Alerts when process limits are met
by David Anderson 01 Sep '12

Hi, Thanks. I used monit, and will code something up of that kind - but I was curious as to whether dovecot had something built in; external monitoring is a somewhat blunter tool, as you don't get to know exactly why there was a problem unless you also parse the logs. Tricky to investigate this kind of issue - it has only happened once, and I had a few hundred people trying to log in, so no time to start debugging! But if it recurs I'll be back to ask for guidance...

Morning all! Total newbie question. I'm learning Dovecot and will be plugging in a few things and testing it end to end. What test structures or tools are available for making sure the install is correct and the parameters are taken? Thanks! Leam -- Mind on a Mission <http://leamhall.blogspot.com/>

[Dovecot] Dovecot generate file when over quota detected
by Dominic Malolepszy 31 Aug '12

31 Aug '12

Hi, I am curious if Dovecot can add an empty file into a Maildir folder as soon as a mailbox has exceeded 100% capacity, and later when it detects the quota has fallen below 100% unlink the file. The idea is the Dovecot LDA would deliver the message and if this caused the mailbox to reach 100%+, add a file into the maibox say "username/Maildir/overquota". Interactions via Dovecot IMAP/POP3 that lower the mailbox usage, for example the user popping, or deleting mail from the mailbox would trigger Dovecot to unlink the file. This means that an MTA can efficiently check for the existence of this 'overquota' file and return a "user(a)domain.com Mailbox full" TEMPFAIL error early during the SMTP transaction prior to accepting any data.

[Dovecot] LDAP auth and multiple attributes to construct the mail path
by Anatoly Ivanov 31 Aug '12

31 Aug '12

Hello, So I am trying to construct mail path for my LDAP user lookups, and i need to use two attributes instead of one. For examle, my LDAP directory has two attributes: departmentAttr and userIDAttr, and I want the maildir to reside in /home/${departmentAttr}/${userIDAttr} Unfortunately, I cannot seem to find a way to configure dovecot this way. Right now, I have something like user_attrs = departmentAttr=mail=maildir:/home/%$/%u But %u is the username (which in my environment can easily change, so I cannot use this for maildir location). Any ideas on how to achieve that? So far I have just one brute-force solution - to create an attribute MailDirAttr, and populate it with concatenation of departmentAttr+'/'+userIDAttr by means of a scheduled task. This sounds like unnecessary information duplication, which is usually a very bad practice. So, again - any ideas? Thank you, Anatoly.

[Dovecot] Variables in LDAP userdb
by Alex Crow 31 Aug '12

31 Aug '12

Hi Timo, Is it OK to have dovecot variables in entries in an LDAP userdb? Say I wanted to set the mail userdb parameter to override mail_location, would it work by having an entry in LDAP (eg for mailMessageStore attrib) like: mdbox:/home/email/%d/%n:INDEX=/home/indexes/%d/%1n/%n:ALT=/home/email_archive/%d/%1n/%n and those % variables will still be expanded by dovecot? Or would I be required to replace them in the LDAP directory with their actual values? Cheers Alex -- This message is intended only for the addressee and may contain confidential information.

[Dovecot] doveadm commands returning 139 at director servers
by Angel L. Mateo 31 Aug '12

31 Aug '12

Hello, I have configured director in front of dovecot imap/pop/lmtp servers. When I need to manipulate a user mailbox, I use doveadm commands at director server's, with -S option. But some commands return exit code 139 when command returns more than 40 entries (I think). For example, the command: sudo doveadm fetch -u amateo hdr mailbox Trash HEADER Subject "nyctalus11/" executed at the backend server returns 952 mails, but executed at director server with -S option, returns only 40 mails and exit code 139. I'm using dovecot 2.1.5 and I attached doveconf -n at director and backend servers. -- Angel L.

[Dovecot] IMAP IDLE - iPhone?
by dovecot＠noboost.org 29 Aug '12

29 Aug '12

Hi All, Probably a very common question now days. I'd like to configure our iPhones at work to go directly to my dovecot server (currently dovecot-2.0.9-2.el6_1.1.x86_64). Using the IMAP IDLE (push email) protocol. Has anyone successfully deployed this? If yes, did you have to use an app from the Apple store? For me the IMAP process works, however it's clearly not notifying the client when new email is detected on the server. cya Craig

This seems to show up when I enable the poolmon script (https://github.com/brandond/poolmon) on all the servers, and all servers start simultaneous logins to each others Dovecot backends. I did notice that the poolmon script has been flapping vhost weights a lot (I am looking at making the script handle transient errors better), which means that it is connecting to the dovecot-director socket every few minutes and changing vhost weights from 100 to 0 and vice-versa.

Having set up my mail server (Dovecot/Postfix), users are experiencing long delays (a couple of minutes) when sending mail from mail client such as Thunderbird - this increases with attachments. Having had a brief discussion with someone, they mentioned that the reason that this may be to do with the size of the mailbox. I couldn't see the rationale behind this unless Dovecot is syncing the mailbox after every sent mail (due to possibly saving the sent item?) The mail is being delivered successfully but the amount of time it is taking to complete the action is far too long! Sorry this is a bit vague but any advice on trying to diagnose the problem would be appreciated. Thanks in advance! Tim

[Dovecot] quota: ignore deleted messages (?)
by Sven Hartge 28 Aug '12

28 Aug '12

Hi! I am currently in the process of preparing a migration of our old Courier-based IMAP/POP server setup to a Dovecot-based one. During this process I came across the following problem with the difference Courier and Dovecot handle deleted messages and mail quota. Quote from http://www.courier-mta.org/imap/README.maildirquota.html: ,---- | The default application configuration that uses this maildirquota | library does not count deleted messages, and any contents of the Trash | folder, against the quota. Messages that are marked as deleted (but not | yet actually removed), or messages that are moved to the Trash folder | (which is subject to automatic purging) do not count towards the set | quota. `---- Ignoring the content (or increasing the quota) of the Trash folder is easy and no problem, but ignoring deleted messages seems impossible without changes to the code. While deleted messages are still stored on the server and still take up space until they are expunged, counting them against the quota is somewhat counter-intuitive because most clients don't show those mails and the normal user is unaware the mails he deleted are still there and take up space. Worse yet, if the client uses move-to-Trash, a user deleting mails will double the used space (until Expunge is used) and this may push him over his quota and thus cause any new mail delivery to fail. Unfortunately as our users are used to the courier way of handling the quota this will cause trouble after the migration. And this setup is run at a University, so I don't have any control over the clients a user uses and the behavior of said clients so I am not able to disable the move-to-Trash feature or force an immediate Expunge after a delete. So I propose an additional flag for the quota_rule config option to be able to enable a more lax interpretation of the quota enforcement: quota_rule = *:storage=1G:ignoredeleted quota_rule2 = Trash:storage=+100M Of course I would then have a nightly cronjob which force-expunges all deleted messages so that users can't store mails infinitely in their mailboxes. Thanks for your time and Grüße, Sven. -- Sigmentation fault. Core dumped.

[Dovecot] Deleting metadata smashes file dovecot.dict
by Andre Gröbe 28 Aug '12

28 Aug '12

Hi, I am using dovecot (see dovecot -n output below) with metadata plugin in my own plugin. I want to insert and delete some large metadata (>4KiB). It seems, that the delete in a second call of my plugin smashes the file dovecot.dict in users dir: 1st call: *dovecot.dict is empty -delete metadata 1 -delete metadata 2 -insert metadata 1 ~8KiB -insert metadata 2 <1KiB *dovecot.dict contains two entries 2nd call: -delete metadata 1 -delete metadata 2 -insert metadata 1 ~8KiB -insert metadata 2 <1KiB *dovecot.dict contains the two entries + some waste If all eight steps are called together (in the same plugin context) the file dovecot.dict seems to be ok. I have created a test plugin to reproduce this behaviour: <http://temp-share.com/show/dPf3myu5W>. It needs the notify and (patched) metadata plugin to run. To get it work i copy an email from one IMAP folder to another (to trigger the copy notifier). It seems, that there is an issue on writing metadata/dict, can anybody reproduce it or knows what is wrong? TIA -- Andre

[Dovecot] Sieve/pigeonhole rejects email addresses for valid UNIX users
by David Anderson 28 Aug '12

28 Aug '12

Self-explanatory, I hope (note the period on the end of the username); sieve/pigeonhole does not allow you to have senders which end with a period, which means that any UNIX users with such usernames who send mail have it rejected by sieve: # useradd testuser. # su - testuser. $ mail david(a)example.com -s 'testing' 123 . [testuser.@levi ~]$ logout # less /var/log/maillog Aug 22 07:50:56 levi dovecot: lda(david(a)example.com): Error: sieve: envelope sender address 'testuser.(a)myhost.example.com' is unparsable Versions: dovecot-pigeonhole-0.2.6-21.el5 dovecot-managesieve-0.2.6-21.el5 dovecot-2.0.18-1_134.el5 Why would anyone have a UNIX username ending in a period? For one, web hosting companies may use your domain name as your username - but be subject to a 32-character limit, so your domain name gets truncated.

[Dovecot] use sieve plugin with variable and folders
by Alano Conraz 28 Aug '12

28 Aug '12

Hello , I'm trying to use the pigeonhole plugin but I'm experiencing configuration problem... Hope you could help me! Firstly : my sieve filter test is the next one : /////////////////// require ["fileinto" , "variables" , "mailbox"]; if address :matches "Delivered-To" "*(a)*.*" { fileinto :create ".INBOX.iop" ; stop ; } //////////////////// I get in the log the following : "error: msgid=<****>: failed to store into mailbox '.INBOX.iop': Invalid mailbox name" And the email is stored in the INBOX (implicit keep was successful) I checked that "lda_mailbox_autocreate" and "lda_mailbox_autosubscribre" are set to "yes". Then , when this problem be solved, I would like to know if it is possible with the sieve plugin to implement the following algorithm : - extract the address from the header field "Delivered-To" and set the variable $delivto to this previous value. - extract the address from the header field "To" and set the variable $to to this previous value. - compare $delivto and $to : if they are diffrent, then redirect the email in the subfolder .INBOX.iop. Thank you for any help!

[Dovecot] plugin development: retrieve username -d -f inside plugins
by Alano Conraz 27 Aug '12

27 Aug '12

Hello, i don't know if it a the right place to ask my question related to the development of dovecot plugins, please correct me if it is not. I'm trying some dovecot plugin development. I did a little plugin that suit my needs but i'd like to go further now... I would like to know if there is a kind of "getenv" function that I could call to retrieve in my plugin the username of the mailbox being delivered by dovecot-lda or served by imap server. For example, when I use the deliver with "cat file.txt | deliver -d " user(a)domain.net" -f "me(a)domain.net" I would like to call a function that could return for me the argument of "-d" or "-f". i'm working with dovecot 2.0.17 by now. Thank you
