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.
by Eddy Ilg|univation 04 Sep '12

04 Sep '12

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

[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

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] deliver doesn't update cache index with mbox

Hello Timo, I'm having a problem with mbox that opening folder is slow when new mails are delivered to a folder. I'm delivering through the deliver program. Deliver updates index files but IHMO not completely correct. Therefore I compared index files before and after: 1.) Just delivered 2.) After accessing through imap via Thunderbird diff looks like (stripped down to the relevant things): INDEX: -first recent uid ......... = 25847 +first recent uid ......... = 25848 -log file tail offset ..... = 16468 -log file head offset ..... = 16468 +log file tail offset ..... = 16828 +log file head offset ..... = 16828 - - sync_mtime . = 2012-08-30 19:38:05 + - sync_mtime . = 2012-08-30 20:09:23 - - dirty_flag . = 1 + - dirty_flag . = 0 - - highest_modseq = 11162 + - highest_modseq = 11163 - - log_offset ... = 16468 + - log_offset ... = 16828 CACHE: -used_file_size ....... = 6385696 +used_file_size ....... = 6392132 RECORD: seq=25663, uid=25835, flags=0x00 - - ext 0 keywords : (0000) - - ext 1 modseq : 11156 (942b000000000000) + - ext 0 keywords : (0100) + - ext 1 modseq : 11163 (9b2b000000000000) - ext 2 mbox : 42923286 (16f58e0200000000) - - ext 3 cache : 0 (00000000) + - ext 3 cache : 6385696 (20706100) - ext 4 header-md5: (00000000000000000000000000000000) + - cache offset=6385696 size=488, prev_offset = 0 + - hdr.BCC: + - hdr.CC: + - hdr.CONTENT-TYPE: 18: Content-Type: text/plain; charset=us-ascii + - hdr.DATE: 13: Date: Thu, 30 Aug 2012 19:37:24 +0200 <some other hdr.xxxxx lines removed> + - size.virtual: 1081 (3904000000000000) Same patterns from record: 25664-25675 What does dirty_flag=1 mean?

[Dovecot] FS Quotas, what am I doing wrong?

I'm not able to get the FS quota module to behave as I expect. Depsite having function fs quotas and dovecot apparently configured to use then, the quotas appear to be empty and/or not configured.

[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

[Dovecot] Dovecot Director Output buffer full
by Dominic Malolepszy 29 Aug '12

29 Aug '12

Hi, I have been seeing the following messages in logs on all my Dovecot servers each running both a dovecot-director instance and a dovecot pop3/imap backend. These logs appear to relate to problems with the director. Aug 28 16:09:52 dovecot01 dovecot: director: Error: director(10.0.0.2:9090/right): Output buffer full, disconnecting Aug 28 16:10:01 dovecot01 dovecot: director: Error: Ring SYNC appears to have got lost, resending Aug 28 16:10:02 dovecot01 dovecot: director: Error: Director 10.0.0.2:9090/right disconnected Aug 28 16:09:51 dovecot02 dovecot: director: Error: director(10.0.0.3:9090/right): Output buffer full, disconnecting Aug 28 16:09:57 dovecot02 dovecot: director: Error: Ring SYNC appears to have got lost, resending Aug 28 16:10:01 dovecot02 dovecot: director: Error: Director 10.0.0.3:9090/right disconnected Aug 28 16:10:02 dovecot02 dovecot: director: Error: director(10.0.0.1:9090/left): Ping timed out, disconnecting Aug 28 16:13:15 dovecot02 dovecot: director: Warning: Delaying new user requests until ring is synced Note dovecot01 has IP 10.0.0.1 and dovecot02 has IP 10.0.0.2 and so on. 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. Is there some sort of limit in the Dovecot Director that is being exceeded that should be tweaked? # 2.1.5: /etc/dovecot-director/dovecot.conf # OS: Linux 2.6.32-279.el6.mccqfix.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.3 (Santiago) auth_cache_size = 100 M auth_default_realm = example.com auth_failure_delay = 5 secs auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = sha1 auth_worker_max_count = 600 base_dir = /var/run/dovecot-director/ director_mail_servers = 10.0.0.1 10.0.0.2 10.0.0.3 10.0.0.4 10.0.0.5 director_servers = 10.0.0.1 10.0.0.2 10.0.0.3 10.0.0.4 10.0.0.5 disable_plaintext_auth = no instance_name = dovecot-dir passdb { args = /etc/dovecot-director/dovecot-sql.conf driver = sql } service director { fifo_listener login/proxy-notify { mode = 0666 } inet_listener { address = 10.0.0.1 port = 9090 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service imap-login { executable = imap-login director inet_listener imap { address = 10.0.0.1 port = 143 } inet_listener imaps { address = 10.0.0.1 port = 993 ssl = yes } process_min_avail = 100 } service pop3-login { executable = pop3-login director inet_listener pop3 { address = 10.0.0.1 port = 110 } inet_listener pop3s { address = 10.0.0.1 port = 995 ssl = yes } process_min_avail = 100 } verbose_proctitle = yes

[Dovecot] Size of Mailbox affecting the sending of mail?
by Tim Smith 29 Aug '12

29 Aug '12

Hi, I didn't know where to post this one so I'll start off with you guys and then try Postfix if I'm barking up the wrong tree! 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

[Dovecot] dsync replication available for testing
by Timo Sirainen 25 Aug '12

25 Aug '12

In dovecot-2.1 hg you can now test dsync-based replication. Everything isn't finished yet, but it appears to work and I've enabled it for my @dovecot.fi mails. Some issues: - public namespace isn't replicated at all - shared namespace is replicated, but not private mail flags - I've only tested SSH replication setup now, not director replication setup (and director setup is still missing many things) - SSH replication setup uses aggregator process, which isn't really necessary and can probably be avoided in future Below is a configuration for virtual user setup. System user configuration works pretty much the same, except doveadm/ssh is run as root. Try first that dsync works successfully with ssh in host1: doveadm sync -u user@domain remote:vmail@host2.example.com and also in host2: doveadm sync -u user@domain remote:vmail@host1.example.com ------ mail_plugins = $mail_plugins notify replication service aggregator { # give enough permissions for mail processes fifo_listener replication-notify-fifo { user = vmail mode = 0600 } unix_listener replication-notify { user = vmail mode = 0600 } } service replicator { # start replication at startup process_min_avail = 1 } plugin { # host1 replicates to host2 mail_replica = remote:vmail@host2.example.com # host2 replicates to host1 #mail_replica = remote:vmail@host1.example.com } #dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} service doveadm { # if you're using a single virtual user, set this to # start ssh as vmail (not root) user = vmail }

by Wagner Michel Martins de Azevedo 24 Aug '12

24 Aug '12

Hi Timo, I'm trying to share two folders. The first one it's public and the other is per user based, using acl's to control access etc . Dovecot create the folders, but when I'll subscribe using ThunderBird client both of them seens like watermarked and has a "mailboxes" folder inside. I can set up the acl's rules using Thunderbird. Log files like mail.log don't show nothing in special and mail.err has nothing. Here is the config. # 2.1.8 (b4cd382b6606): /etc/dovecot/dovecot.conf# OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.5 /etc/dovecot/conf.d/10.mail.conf namespace { type = public separator = . prefix = public. location = mdbox:/var/mail_shares/public:INDEX=/var/mail_shares/public subscriptions = no}namespace { type = shared separator = . prefix = %h/shared location = mdbox:%h/shared:INDEX=%h/shared subscriptions = no list = children} Thanks, Wagner Azevedo

[Dovecot] enabling per user quota plugin and problems with pop3
by Angel L. Mateo 24 Aug '12

24 Aug '12

Hello, I am configuring quota plugin per user, not for the whole system. As documentation says (http://wiki2.dovecot.org/Quota) I have to add "quota" to the global mail_plugins and "imap_quota" to mail_plugins for protocol imap, but I don't know how to configure this in a userdb. I'm using a passwd-file in the way: <user>:{plain}password:<uid>:<gid>::<home>::userdb_mail_plugins=quota,imap_quota but this activate both plugins in the global mail_plugins option. The problem with this is that if the user tries to connect via pop3 instead of imap (a thing that I permit, although the user shouldn't do it) I have the error: Aug 20 10:04:18 myotis30 dovecot: pop3: Error: dlopen(/usr/lib/dovecot/modules/lib11_imap_quota_plugin.so) failed: /usr/lib/dovecot/modules/lib11_imap_quota_plugin.so: undefined symbol: client_send_tagline is there any way to solve this problem? -- Angel L.

Re: [Dovecot] problem with virtual plugin/index files?

Hello, Timo: on Oct 29th I wrote ---- with latest 2.0.6 (601065674f74), the following virtual mailbox is not behaving correctly. I'm quite sure that the problem has not existed in some earlier 2.0.x (maybe only INBOX as mailbox then though): ~user/Maildir/virtual/.week/dovecot-virtual contains INBOX INBOX.* -INBOX.Trash inthread refs younger 604800 This works as expected for the first time. But later on, also older messages/ threads are included until I delete the virtual/.week/dovecot.index*. ---- Just want to state that this problem still persists with latest version. Any idea?
