[Dovecot] precise reading of plugin deleted to trash
by ml 10 Sep '12

10 Sep '12

hello timo and other dev after a precise reading of plugin deleted to trash it appears to me like things more varariables are declared NULL in the code. it appears to me as being possible to achieve actions even if messages with the same id appears several times in different INBOX when it is the exact order of things -- http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xC2626742 gpg --keyserver pgp.mit.edu --recv-key C2626742 http://about.me/fakessh http://urlshort.eu fakessh @ http://gplus.to/sshfake http://gplus.to/sshswilting http://gplus.to/john.swilting https://lists.fakessh.eu/mailman/ This list is moderated by me, but all applications will be accepted provided they receive a note of presentation

[Dovecot] ChgrpNoPerm issue
by Robert JR 09 Sep '12

09 Sep '12

I have dovecot version 2.0.9 I am confused about this article http://wiki2.dovecot.org/Errors/ChgrpNoPerm my mail_location = mbox:~/mymail:INBOX=/var/mail/%u So my inbox is at var/mail/ and my imap folder is /home/user/mymail The problem is /var/mail (Owner is useraccount and the group us mail) , and here comes the problem Dovecot keeps trying to chown the imap folder inside the homedirectory with user:mail account and since And this is the reason of error that appears in my log file. The option mail_access_groups=mail solve the problem.. but I read it is not secure.. With my current configutation, users login with imap to read mail , can they use any the mail_access_groups=mail and read other poeple mail ? does my configutation is a shard mailbox and could be unsecure.. my main quesion , for my current configuration , can i use mail_access_groups=mail safely or can some user use this to read other people mail ? attached my configuration. why didnot have this issue with uw-imapd? and why dovecot try to chown the .imap folder with the mail group ? dovecot -n output is # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.2.1.el6.x86_64 x86_64 CentOS release 6.3 (Final) disable_plaintext_auth = no mail_debug = yes mail_location = mbox:~/mymail:INBOX=/var/mail/%u mbox_write_locks = fcntl passdb { driver = pam } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } [ Robert

[Dovecot] Auth worker max line size
by Emmanuel Dreyfus 09 Sep '12

09 Sep '12

Hello I have been playing with some exotic authentication scheme with Dovecot and PAM. That involves sending really large base64 encoded data as the IMAP password, and I have hit a line limit in Dovecot, with AUTH_WORKER_MAX_LINE_LENGTH set to 1024. This limit is especially frustrating since other parts of the software use much larger limits: MAX_INBUF_SIZE 4096 MAX_IMAP_LINE 8192 AUTH_CLIENT_MAX_LINE_LENGTH 8192 I had to make the patch attached below to get my authentication working. I can live with this local patch, but given the much more liberal limits of MAX_INBUF_SIZE at 4096 makes we wonder if this 1024 limit on AUTH_WORKER_MAX_LINE_LENGTH could not be a bug. Or is there a security concern at using more than 1kB? Opinions?

[Dovecot] Vpopmail Dynamic Authentication Module
by Eric Sisolak 08 Sep '12

08 Sep '12

Hello, We currently use qmail with vpopmail for e-mail and are looking to switch from courier-imap to dovecot for IMAP on our RedHat EL 5 systems. Our goal is to use the dovecot RPM supplied by RH (v1.0.7) if at all possible. We can do this if we are able to dynamically load the vpopmail auth module. The wiki (http://wiki.dovecot.org/CompilingSource) notes that this should be possible: Dovecot can also dynamically load authentication modules from the $prefix/lib/dovecot/auth/ directory. Binary packages builders should use them for authentication modules which require external libraries (e. g. LDAP and vpopmail). There is no standard way to build them as modules currently, but something like this should work: gcc -shared -fPIC -DHAVE_CONFIG_H -DUSERDB_VPOPMAIL -DPASSDB_VPOPMAIL \-I../.. -I../lib userdb-vpopmail.c passdb-vpopmail.c -o vpopmail.so \-lvpopmail I had to modify the command to build the module, but was able to successfully build it: gcc -shared -fPIC -DHAVE_CONFIG_H -DUSERDB_VPOPMAIL -DPASSDB_VPOPMAIL -I../.. -I../lib -I/home/vpopmail/include -I/home/vpopmail/lib userdb-vpopmail.c passdb-vpopmail.c -o vpopmail.so -L/home/vpopmail/lib/libvpopmail.a I am unable to get the module to load properly. Dovecot built with --with-vpopmail works perfectly. When I start dovecot and it tries to load the module it reports: Aug 23 16:48:18 ctd-nix1 dovecot: Dovecot v1.0.7 starting up Aug 23 16:48:18 ctd-nix1 dovecot: auth(default): dlopen(/usr/lib64/dovecot/auth/vpopmail.so) failed: /usr/lib64/dovecot/auth/vpopmail.so: undefined symbol: vclose Aug 23 16:48:18 ctd-nix1 dovecot: auth(default): dlsym(passdb_vpopmail) failed: dovecot-auth: undefined symbol: passdb_vpopmail Aug 23 16:48:18 ctd-nix1 dovecot: auth(default): Unknown passdb driver 'vpopmail' (typo, or Dovecot was built without support for it?

I upgraded dovecot from 1.1 to 2.1.8 pop3/imap works but i have a problem. i use pop3 protocol on outlook 2010 for my account. and i set keep my mails on the server for 5 days or until i delete them. These settings were working old dovecot1.1. But when i upgraded it to 2.1.8. if i even delete a mail from outlook the server doesn't delete or old mails are not deleted. what can be the problem ? thanks -- View this message in context: http://dovecot.2317879.n4.nabble.com/problem-about-pop3-using-dovecot-tp373… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Disconnect users for a distinct period of time?
by Michael Grimm 07 Sep '12

07 Sep '12

Hi -- Today, I've learned who to disable incoming mail delivery to dovecot (accepted by postfix), temporarily. Now, I would like to know if there is a way to make a "doveadm kick -A" a permanent disconnect until one would allow reconnects, again? This should be done *without* shutting down dovecot or *extensive* re-configuration. A "doveadm block -u <joe> -m 'sorry: running maintenance, please, come back later'" alike tool/funtionality would be ideal. Background: I would like to avoid any modification of my user's maildirs by a running dovecot server while modifying maildir formats, mdbox_rotate_size setting, and alike, where I would need doveadm/dsnyc access to userdb. (I know there a ways to achieve this without downtimes, and I have already done so.) I just want to be sure that I haven't overseen such a tool/functionality in the documentation. Did I or didn't I? Thanks and regards, Michael

I'm not sure that the auth cache holds that information, but I think you can at least invalidate a particular auth cache entry by 1) Changing the user password (and save the previous hash) 2) Authenticate using the new credentials (and invalidate the auth cache entry). For example, you can just do a manual connection on your dovecot server x login someuser newpassword This will replace the cache entry with a new one. 3) When you are ready to put the account back online, change the password back to the original. A password mismatch forces a resync to your authentication system which will restore the auth cache. Joseph Tam <jtam.home(a)gmail.com>

[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] Length of attachment filenames

[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

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.

[Dovecot] Testing process?
by leam hall 01 Sep '12

01 Sep '12

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

[Dovecot] Dovecot Director Output buffer full

These logs appear to relate to problems with the director.

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.

[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!

I've looked at http://wiki2.dovecot.org/Tools/Doveadm/Mailbox and there a few features I like which javax.mail just doesn't have. Is there maybe a Java driver for doveadm? thanks, Thufir

[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

Hi, is it possible to configure dovecot so that it only serves mailboxes of specified users? All other users should be completely ignored so that no indexing of messages or other resource consuming actions take place. Thanks in advance, Alex

[Dovecot] UIDPLUS for Maildir?
by Martin Rabl 25 Aug '12

25 Aug '12

Hi, I found the following comment in the documentation (http://wiki.dovecot.org/FeatUIDPLUS) last edited on 2009-03-15 > Dovecot already supported UIDPLUS at one point for mbox, but implementing it > for Maildir has to be done differently (UIDs are allocated later with Maildir). > So currently the UIDPLUS code is removed until it can be made to > work with Maildir. My question: does this extension now run with maildir? Thank you, Martin

[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 }

[Dovecot] Shared mdboxes
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.

[Dovecot] userdb multiple databases
by Angel L. Mateo 23 Aug '12

23 Aug '12

Hello, I'm trying to configure per user plugins. My original passdb and userdb is in a ldap directory (using userdb with prefetch). To configure per user plugins (in fact, I want to enable quota plugin for some users) I need to configure mail_plugins attribute in the userdb. The problem is that I don't know any ldap attribute to store this information (is there any schema with includes an attribute for this). So I want to configure it in a passwd-file file. My problem is that I don't know if I can chain userdb databases. I know I can configure multiple databases, but as far as I know, they are looked in order, so if the user is found in the first one, then is no look for the user in the second one, so I have to configure all user's attributes in the passwd-file database. Is there any way to chain these lookups? -- Angel L.

[Dovecot] No status for INBOX/* in mbox NS (2.1.6)
by Jost Krieger 23 Aug '12

23 Aug '12

Maybe it's fixed, but the last "interesting" text in the Changelog was before 2.1.6. Most of our users still have mboxes in the classical layout, so you can't have subfolders and messages in the same folder, *except for the INBOX*, as it is physically separate. Someone complained that he saw subfolders in roundcube he couldn't delete, because they didn't show up in the subscription view. Before hitting on roundcube, I mperformed a few checks and got the following: root@cx-y-z qmail # doveadm mailbox status -u usera messages 'INBOX/*' root@cx-y-z qmail # doveadm mailbox status -u usera messages 'INBOX/test1' INBOX/test1 messages=0 This is mysterious. It doesn't happen with my account, that is in a mdbox: root@cx-y-z qmail # doveadm mailbox status -u kriegjcb messages 'INBOX/*' INBOX/test1 messages=1 Our setup is a bit complicated, but most of it shouldn't be relevant to the problem. # 2.1.6: /usr/local/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.9-103.ELsmp i686 Red Hat Enterprise Linux AS release 4 (Nahant Update 9) auth_first_valid_uid = 100 auth_master_user_separator = * dict { quota = mysql:/usr/local/dovecot/etc/dovecot-dict-mysql.conf } disable_plaintext_auth = no first_valid_uid = 100 lda_mailbox_autocreate = yes log_path = /dev/stderr log_timestamp = mail_access_groups = nofiles mail_location = mbox:~/Mail:INBOX=~/Mailbox:INDEX=~/Index mail_plugins = " quota zlib mail_log notify virtual stats" mdbox_rotate_size = 5 M namespace { hidden = no inbox = yes location = prefix = separator = / type = private } namespace { hidden = yes inbox = no list = children location = maildir:~/Maildir prefix = "#MD/" separator = / type = private } namespace { hidden = yes list = no location = virtual:~/Maildir/Virtual prefix = Virtual/ separator = / type = private } namespace { hidden = yes list = no location = virtual:/usr/local/dovecot/etc/virtuell:INDEX=~/Virtuell prefix = Virtuell/ separator = / subscriptions = no type = private } passdb { driver = pam } passdb { args = /usr/local/dovecot/etc/passwd.dovcot.master driver = passwd-file master = yes } plugin { acl = vfile mail_log_events = undelete mailbox_delete mailbox_rename mailbox_create mail_log_fields = uid box msgid size quota = dict:User quota::proxy::quota quota2 = fs:Disk quota stats_refresh = 30 secs stats_track_cmds = yes } protocols = pop3 imap service auth { client_limit = 4300 user = root } service dict { unix_listener dict { group = nofiles mode = 0666 } } service doveadm { inet_listener { port = 542 } } service imap-login { inet_listener imap { address = 134.147.64.38 port = 143 } service_count = 0 } service imap { drop_priv_before_exec = yes process_limit = 2048 vsz_limit = 1 G } service pop3-login { inet_listener pop3 { address = 134.147.64.38 port = 110 } service_count = 0 } service pop3 { drop_priv_before_exec = yes process_limit = 2048 vsz_limit = 512 M } service stats { fifo_listener stats-mail { mode = 0666 user = dovenull } } ssl = no stats_command_min_time = 5 mins stats_domain_min_time = 1 hours stats_ip_min_time = 1 hours stats_memory_limit = 64 M userdb { args = /usr/local/dovecot/etc/dovecot-mysql.conf driver = sql } userdb { driver = passwd } protocol imap { mail_max_userip_connections = 50 mail_plugins = " quota zlib mail_log notify virtual stats imap_quota imap_zlib imap_stats" } Thanks Jost Krieger -- | Helft Spam ausrotten!

[Dovecot] For the wishlist
by Jost Krieger 23 Aug '12

23 Aug '12

I would like very much to have a "doveadm copy", which probably could be made out of "doveadm move" by removing ca. 2 lines (and changing a few strings from "move" to "copy"). This would make it a lot easier to script quite a few things without using a real imap client. I can run around this by doing an import followed by a move but this will duplicate the mails (even when using mdbox). Mit freundlichen Grüßen Jost Krieger -- | Helft Spam ausrotten!

[Dovecot] Dovecot / Win8 Mail App Folder Subscription Issue
by Adam Rosi-Kessel 23 Aug '12

23 Aug '12

Win8 RTM Mail App now supports IMAP. I am running Dovecot 1.2.15 on a Debian Stable server. The App works fine except the list of folders displayed seems to be a random subset of all my folders. I can't figure out how it's picking which folders to show, or how to change what's subscribed. Editing the "subscriptions" folder in ~/Maildir/ doesn't seem to have any impact. Any suggestions on how to troubleshoot or narrow done this issue? I posted to a Microsoft forum but was told the Mail App will only support official email providers.

[Dovecot] doveadm director move behaviour
by Angel L. Mateo 23 Aug '12

23 Aug '12

Hi, I have a director farm running in front of dovecot pop/imap servers. For a reason, one of my backend servers have been down, so poolmon disables it in director servers and users corresponding to it has been sent to other servers. Until this, no problem. Now my failed backend server is up again, and I want to redirect all of its users to it, without waiting for it director sessions to end. So I have used doveadm director move <user> <backend ip> to move them to its "hashed" server. Although a doveadm director status <user> now shows me that this user is directed to the new server, doveadm who in the temporal server shows me that the user is actually connected to it, although messages are delivered to it through is correct server. So I have had to manually kick that users in the temporal servers. Is this the expected behaviour of the move command for director? Is there any way to also force the kick of the imap/pop user's connection in the temporal server? -- Angel L.

[Dovecot] more dsync issues
by Jeff Gustafson 23 Aug '12

23 Aug '12

It hit another dsync snag. We have a script that executes a dsync backup command to a remote host. No write should be happening on the remote host (the backup host). The error is: dsync-local(anonymous(a)domain.com): Error: remote: dsync-remote(anonymous(a)domain.com): Error: Can't delete mailbox INBOX: INBOX can't be deleted. dsync-remote(anonymous(a)domain.com): Error: command MSG-SAVE failed dsync-local(anonymous(a)domain.com): Error: read() from worker server failed: EOF dsync-local(anonymous(a)domain.com): Error: Unexpected reply from server: dsync-local(anonymous(a)domain.com): Warning: Mailbox changes caused a desync. You may want to run dsync again. We're currently running 2.1.7 since > 2.1.8 causes a problem with our webmail software. ...Jeff

[Dovecot] blf-crypt
by Sven Schwyn 23 Aug '12

23 Aug '12

Hi The blf-crypt password schema mentioned in the docs could be a solution to my auth problem. However, the docs state that actual support depends on the glibc. Mine apparently doesn't. Does support depend on the glibc's version (mine is 2.15-r2)? Maybe someone with access to a box with a good enough glibc could do the following and post the hash for the plain password "test"? doveadm pw -s BLF-CRYPT Enter new password: test With this I could verify whether the BLF-CRYPT scheme would solve my problem in the first place without going through the hassle of upping the glibc. Thanks a bunch!

[Dovecot] difference between namespace auto=subscribe and autocreate plugin
by Igor Zinovik 22 Aug '12

22 Aug '12

Hello. I read docs, but still do not understand difference between following configuration options: namespace inbox { # Create and subscribe to folder mailbox Drafts { auto=subscribe } and `autocreate' plugin plugin { autocreate = inbox.Drafts autosubscribe = inbox.Drafts On wiki page that describes `autocreate' plugin i read: ... mailboxes that must always exist for all users. So even if user delete Drafts IMAP folder on next connection server will create it. Is `mailbox' undocumented feature? I see it only in configuration file, but wiki does not mention it.

[Dovecot] How dovecot treats UTF8 mailbox names in sieve scripts and `namespace' section
by Igor Zinovik 22 Aug '12

22 Aug '12

Hello. I read on upgrading page that one can use UTF8 mailbox names for plugins. As i understand i do not need to convert UTF8 names to mUTF-7 and can use raw UTF8 in plugins section, e.g.: /etc/dovecot/dovecot.conf ... plugin { ... # Autocreate \Spam folder autocreate = Спам autosubscribe = Спам ... But what about sieve scripts and other configuration sections: 1. Do i need to convert UTF8 mailbox names in `namespace' section? namespace inbox { ... mailbox &BCEEPwQwBDw- { special_use = \Junk } 2. Do i need to convert UTF8 mailbox names in sieve scripts? /etc/dovecot/dovecot_before.sieve ... require ["reject","fileinto"]; # Put all spam into separete IMAP folder if header :contains "X-Spam-Flag" "YES" { fileinto "&BCEEPwQwBDw-"; }

[Dovecot] [PATCH] Replace hard-coded PKG_STATEDIR with state_dir setting
by Chris Webb 22 Aug '12

22 Aug '12

Sharing an installed copy of dovecot between several users each running a daemon within their own account (or using the same binaries for a system daemon and a user daemon) is difficult because the compile-time directory PKG_STATEDIR (typically /var/lib/dovecot) is hard-coded as the location of things like the ssl-parameters.dat file and the replicator database. Replace all these uses of PKG_STATEDIR with a state_dir setting which defaults to PKG_STATEDIR but can be overridden in dovecot.conf, in the same way base_dir can be used to override PKG_RUNDIR.

[Dovecot] Search extensions
by Timo Sirainen 21 Aug '12

21 Aug '12

I'm thinking about adding at least one new SEARCH command extension to Dovecot: ability to search from any headers in the mail, including MIME headers in the body. So the idea is that you could somewhat quickly ask e.g. "show me all mails with pdf attachments": a search or x-anyheader application/pdf x-anyheader .pdf b fetch $ bodystructure The client can verify the results with the fetch. The "x-anyheader" can already be implemented without changes to full text search plugin, because all backends store message/MIME headers and body text separately. So, questions for the list, especially client developers: 1) What's a better name for x-anyheader? :) 2) Any other ideas about search extensions you'd want to see? Maybe I could get this standardized at some point. I think one other thing missing has been "show me messages that have attachments". I've thought about maybe creating a $hasattachments keyword for that, which the server could automatically set for new mails that it thinks has attachments (and clients can set/unset the keyword if wanted).

[Dovecot] Spaces in DN with AD auth
by Chris Visser 21 Aug '12

21 Aug '12

Hi guys, I'm back to fiddling with my Dovecot and AD intergation and I've noticed that if a DN contains spaces, dovecot doesn't bind to the AD server. I'm running: dovecot-2.1.1 exim-4.72 on CentOS 6.3 Exim binds fine with the DNs containing spaces, it's just dovecot that exhibits the symptoms.

[Dovecot] namespace from snapshots
by Karl Oulmi 21 Aug '12

21 Aug '12

hi all, I'm trying to give access to snapshots taken from by dell iscsi MD3200i to my maildirs users. snapshot are mounted in read only mode from my FreeBSD box. In my /usr/local/etc/dovecot/conf.d/10-mail.conf, I have : namespace inbox { inbox = yes } namespace da1 { prefix = INBOX.backup.da1. hidden = no list = yes inbox = no location = maildir:/da1/%u/Maildir type = private } I have two problems : - In my log, dovecot complain about the fact that my snapshot filsystem is read only Error: open(/da1/test2(a)toto.com/Maildir/.Trash/dovecot-uidlist) failed: Read-only file system The second problem is that through my thunderbird I can't see the Inbox saved in the snapshot (whereas I see Sent and Trash folders) If anyone could help me, It would be nice. Regard, Karl.

(Like Apache VirtualHosts) I doubt it; the virtual name is not part of the IMAP protocol as it is in HTTP. The IMAP server is not told which hostname was mapped to its IP. You'll either have to add the @domain, or perhaps multi-home your host, remap one of your domains to the new IP, and add another running instance of dovecot to listen on that interface.

[Dovecot] Full text search in attachments

Hello, is it possible to use the Solr full text search plugin for indexing mail attachments? I found a very old patch and some hints regarding a fts_decoder script that I don't understand. Making Solr indexing PDF or Office files shouldn't be that difficult, but how can I enable the plugin to transfer the attachments to Solr? Best regards, Sebastian

[Dovecot] case insensitive acl
by Andre Rodier 19 Aug '12

19 Aug '12

Hello, I have notice that when I use ACL, the name of the user in the dovec-acl-list file is case sensitive. Because I use LDAP, the name of the users is case insensitive. Would it be possible to have an option in Dovecot, to ignore the case of the ACL ? This would be useful with some ACL managers, like roundcube ACL plugin, that uses an LDAP query to autocomplete the user name for the ACL. Kind regards, André

[Dovecot] dsync \noselect on INBOX.INBOX skips sync of INBOX
by Nikolai Schupbach 19 Aug '12

19 Aug '12

Hi Timo, We have encountered an issue today with a number of migrations. Some customers have mailboxes on the source IMAP server that look like this: 3 LIST "" * * LIST () "." "INBOX" * LIST () "." "INBOX.Statements" * LIST () "." "INBOX.Draft" * LIST () "." "INBOX.Drafts" * LIST () "." "INBOX.Invoices" * LIST (\Noselect) "." "INBOX.INBOX" * LIST () "." "INBOX.Jokes" * LIST () "." "INBOX.Payslips" * LIST () "." "INBOX.Personal" When we run dsync it skips the INBOX presumably because of the Noselect on INBOX.INBOX. and the "imapc_list_prefix = INBOX" setting. Regards, Nikolai.

[Dovecot] maildir to sdbox offline conversion
by _ET_ 19 Aug '12

19 Aug '12

Hi all. I've just installed dovecot v2.1 in a multihomed, multiinstance setup, It took me two days to convert the old v1.1 configs, now everything works like charm! But. :) I have several maildir mailboxes, I decided to use the sdbox storage type instead. I ran into difficoulties using the dsync util. My virtual users are in an OpenLDAP DB on a differnet machine, and I do not have access to the database (I can authenticate the users from ldap, but cannot change or see anything) So it's not easy to do an "online" conversion and follow the instructions at dsync's wiki. Do you know a way how to simply tell dsync or a similar util the following dsync convert maildir:/data/vmail/domain/user sdbox:/newdata/vmail/domain/user without touching the ldap database, only the files on the disk. I can run this command as root on this mail server, if it is needed, I can run the command for each and every maildir. That's not a problem. any ideas, how this wouléd be the simpliest? -- View this message in context: http://old.nabble.com/maildir-to-sdbox-offline-conversion-tp34274589p342745… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Dsync and SIS
by Alex Crow 19 Aug '12

19 Aug '12

Hi all, Just to clarify, if we back up a dovecot 2 server with SIS for attachments and ALT storage by rsyncing it (including the SIS and ALT storage) to a remote server when it's idle (or at least almost entirely so), and run dovecot on that machine, would it seem feasible to restore backups from that server by using dysnc - specifically for the scenario where someone accidentally deletes emails/folders etc.? I've seen queries about SIS before but nothing specifically about this scenario. Cheers Alex -- This message is intended only for the addressee and may contain confidential information.

[Dovecot] Listen on multiple ports possible using same protocol?
by Michael Durket 18 Aug '12

18 Aug '12

Is it possible to have multiple Listen directives in a dovecot configuration file for the same protocol? I am running dovecot-1.2.11 and I want to be able to use the "standard port" as well as a test port: protocol imap { listen = *:143 listen = *:10143 ssl_listen = *:993 ssl_listen = *:10993 for example. Or is this more preferably done by pointing dovecot at different configuration files?

[Dovecot] Expire-tool does not delete duplicate messages (dovecot-1.2.17)
by Oleksii Krykun 17 Aug '12

17 Aug '12

Trying to implement expire plugin. expire-tool works fine. This delete expunged messages but not all of them. I have duplicate messages in appropriate folder. These messages are from expanding postfix aliases (e.g. postmaster@, hostmaster@, abuse@ etc. points to same mailbox and spam often sent to all of them. If duplicate message is received only one entry in dovecot-uidlist is created and only first of duplicates is deleted with expire-tool. Rest of duolicates are not deleted. Any suggestions.

[Dovecot] dsync backup gets stuck... fails
by Jeff Gustafson 17 Aug '12

17 Aug '12

More dsync issues. We were running 2.1.7 and we updated to 2.1.9. Same problem with both versions. I'm getting an error 75 on about 40 boxes out of 1800. It is the same list of boxes every time we use 'dsync backup' to backup the server. dsync seems to stop communicating to the backup box (over ssh). strace just shows it sitting at a epoll_wait. Once the program quits (times out?), a 'du' shows the destination is smaller (200kbyte in one case). Has anyone else seen an exit code of 75? Nothing in the documentation mentions what exit code 75 could mean. What can I do to help the developers locate the bug? ...Jeff

[Dovecot] some mdbox mails get lost each day
by Christian Rößner 16 Aug '12

16 Aug '12

Hi, I have a strange problem here. I had installed Dovecot-2.1.6 on a customers setup. They have 102 mail accounts on the server. The started using this dovecot version on the 20th June. One mailbox suddenly started expunging mails. Not from the current day, but one week back in the past. First I thought about an Outlook issue. Some filter or archieving thing, but we did a test and on one day, the curstomer did not start Outlook first; instead he checked his mails with the SOGo-webinterface. We saw that mails got deleted again. I checked for sieve filters. None. I upgraded dovecot to 2.1.7, as I have not done any newer packages yet for Ubuntu (using my own PPA). Same problem one day later. I tested with telnet locally. Same result as in the client. I also did doveadm dump -t log and index and saw that there had been expunged mails. Yesterday I asked the customer to backup all his mails in Outlook. After that I renamed the whole mdbox folder of this account on the server and sent one test mail to recreate the mailbox. After that her restored his mail in Outlook. This morning her contacted me and said that all mails are ok right now and no mails have been erased anymore. Coud this been a corrupted index? I also chekced the storage/-folder and see that all mails are still on disk. Now he asked me if there is any way to get all the lost messaged back? It would be okay for him, if all mails since June are sent again, as he can clean his mailbox afterwards. So does somebody have an idea on how to solve this? Maybe scripting something in python and using local sendmail command? Or is there some doveadm voodoo to repair the index or unexpunge all mails?

[Dovecot] Hostname Based forwarding
by Merrickville 16 Aug '12

16 Aug '12

Trying to figure out hostname based IMAP proxy forwarding. I have two mail servers: mail.example.com mail.fakedomain.ca proxy server running dovecat/IMAPS, facing the Internet. *Both* names are DNS resolve(able), but.., both are the *same IP address.* For example: Joe configures his email client username: joe(a)example.com IMAP Addr: mail.example.com For example: Jane configures her email client username: jane(a)fakedomain.ca IMAP Addr: mail.fakedomain.ca So, now all clients must change their user-name in their email client to their full email address, because there is a Jane & Joe on "both" servers and..., dovecot proxies based on 'user name' Is there a way to proxy based on the host name the client has configured in his/her email client? (Like Apache VirtualHosts) This would be ideal, as the clients can then go back to using just their name as the username.

[Dovecot] v2.2 status update: IMAP NOTIFY extension and more
by Timo Sirainen 16 Aug '12

16 Aug '12

v2.2 hg now has support for NOTIFY extension. The only thing missing is support for SubscriptionChange events. Now would be a good time for IMAP clients to start implementing and testing it. :) I remember K9 developers at least said they were just waiting for Dovecot to support it first. v2.2 implements some other extensions also: BINARY, CATENATE and MOVE. Stephan has also implemented URLAUTH pretty far. Hopefully it gets finished in time for v2.2.0. I'll also try to implement the rest of the LEMONADE extensions: CONVERT, CONTEXT=SORT and URLAUTH=BINARY. I'm also considering implementing an SMTP submission server, which works only as a proxy to the real SMTP server. The benefits of it would mainly be: * It could support BURL command and other extensions required by LEMONADE. The real SMTP server would see only regular DATA commands. * Would make SMTP AUTH easy to implement regardless of what the real SMTP server is.

[Dovecot] Postfix & Dovecot: Client certificate authentication

Here are the postfix logs: Aug 16 09:51:48 myserver dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Aug 16 09:51:48 myserver dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Aug 16 09:51:48 myserver dovecot: auth: Debug: auth client connected (pid=6922) Aug 16 09:51:51 myserver dovecot: auth: Debug: client in: AUTH 1 PLAIN service=smtp nologin lip=127.0.0.1 rip=127.0.0.1 secured resp=xxx Aug 16 09:51:51 myserver postfix/smtpd[6922]: warning: localhost.localdomain[127.0.0.1]: SASL PLAIN authentication failed: Client didn't present valid SSL certificate Aug 16 09:51:51 myserver dovecot: auth: PLAIN(?,127.0.0.1): Client didn't present valid SSL certificate Aug 16 09:51:51 myserver dovecot: auth: Debug: client out: FAIL 1 reason=Client didn't present valid SSL certificate Aug 16 09:51:51 myserver dovecot: auth: Debug: client in: AUTH 2 LOGIN service=smtp nologin lip=127.0.0.1 rip=127.0.0.1 secured Aug 16 09:51:51 myserver dovecot: auth: LOGIN(?,127.0.0.1): Client didn't present valid SSL certificate Aug 16 09:51:51 myserver dovecot: auth: Debug: client out: FAIL 2 reason=Client didn't present valid SSL certificate Aug 16 09:51:51 myserver postfix/smtpd[6922]: warning: localhost.localdomain[127.0.0.1]: SASL LOGIN authentication failed: Client didn't present valid SSL certificate It seems Postfix doesn't send the client certificat to Dovecot.

[Dovecot] bcrypt again
by Sven Schwyn 15 Aug '12

15 Aug '12

Hi I'd like Dovecot to consume a list of users exported from an external application which stores bcrypted passwords. This has been asked in the past, however, I'm not sure how to read the following reply: > If you are using Dovecot< 2.0 you can also use any of the algorithms > supported by your system's libc. But then you have to prefix the hashes > with {CRYPT} - not {{BLF,SHA256,SHA512}-CRYPT}. I'm on Dovecot 2.0.19. Does this mean that only the hashes listed with "doveadm pw -l" are supported and even if glibc can do bcrypt, the CRYPT scheme won't do the trick anymore? Thanks for your help!

Hi to all Here is the following scheme: Dovecot in a link with AD. For LDA and IMAP different views are used in a base.

Incoming male folds up in /var/mail/domain/auth_1.name When vacation is on, the letters from 1.name(a)domain.ltd are sent in a following way auth_1.name(a)domain.ltd I guess the problem is in two different data-base queries.

[Dovecot] Libdovecot-sieve segfaults

Hello Stephan, Preface - one of my users went to vacation and changed his sieve script to run autoreply vacation message, after that - I have noticed some annoying errors in system log, like: dovecot-lda[2400]: segfault at 3eb3333f ip b7446c7a sp bfaab050 error 4 in libdovecot-sieve.so.0.0.0[b7429000+5b000] Dovecot-error log is empty, but in exim log(exim runs dovecot-lda) I got: 2012-08-13 09:35:27 1T0oFK-0000aW-6j ** sr(a)domain.com (sr(a)domain.com, root(a)domain.com) <postmaster(a)domain.com > F=<59942270813(a)mymail.in.ua> R=ldap_accept T=local_delivery: Child process of local_delivery transport (running command "/usr/libexec/dovecot/dovecot-lda -e -d $local_part@$domain") was terminated by signal 11 (Segmentation fault) sr(a)domain.com - is the user, who created such sieve-script, which cause segfaults. I have tried run the same message over this script from sieve-test utility - but result is success. Can you please, take a look to this sieve script and check is it ok, I'll send it to you privately since it contains user's data. Also I'll attach message.eml which triggers segfault. Dovecot version - 2.0.21, Sieve version - 0.2.6.

[Dovecot] HA Mailbox Design
by Nikolaos Milas 13 Aug '12

13 Aug '12

Hi, We would like to implement a Highly Available Mail Server and would like to ask advice on how to architect this. Some details on our setup: Currently we have only one internal mail server (Postfix/Dovecot 2.0 - planning to move to 2.1), receiving mail from a gateway server (filtering spam/viruses) - a Cisco Ironport - which we are considering to replace with one (or a set of) cloud-based Postfix/Amavis-new/SpamAssassin/ClamAV VMs (currently in testing mode). Delivery uses Dovecot LDA. User accounts are LDAP-based. We use Maildir and the load is low (aside spam). Only about 250 users/mailboxes (4G each). All servers are CentOS 5.8 (planning move to 6.3) KVM VMs (on a cloud where we don't have control on the host, but on highly reliable hardware/networks). We can have VMs on two different clouds and we also have at least two different connections (routes) to the cloud(s) (to support HA). Any directions will be appreciated. Hoping to design an HA architecture but aiming to keep it simple and (as much as possible) easily maintainable one. Thanks for your response and help, Nick

[Dovecot] Running spamc during LMTP delivery
by martin f krafft 12 Aug '12

12 Aug '12

Hello list, we are using dovecot-lmtp for delivery to virtual users, and vmm[1] to manage them. 1. http://vmm.localdomain.org/ One nice feature of vmm is that every virtual user has their own UID/GID on the UNIX filesystem. There is no passwd entry, so no shell login, but each user effectively has a home directory and can run commands in isolation and with lowered privileges. This requires dovecot-lmtp because only the LMTP LDA runs with root rights and can drop privileges to become the specific user for which it is delivering mail. We would now like to run SpamAssassin with the possibility of using the antispam plugin to enable virtual users to train their databases. Do you have an idea how I could let dovecot-lmtp invoke spamc? Or an external command as a filter, to be run by the final user? Thanks, -- martin | http://madduck.net/ | http://two.sentenc.es/ "truth is stranger than fiction, but it is because fiction is obliged to stick to possibilities; truth isnt." -- mark twain spamtraps: madduck.bogus(a)madduck.net

This is the hard part. Depending on your preferred distro here are two nice webpages for this: http://wiki.mediatemple.net/w/(ve):Install_Postfix_with_Dovecot_on_CentOS http://workaround.org/ispmail Second step is to enable sieve, for witch you only need to uncomment the specific lines from dovecot.conf. For dovecot 1.2, you will have something like: protocols = pop3 pop3s imap imaps managesieve protocol lda { ... mail_plugins: quota sieve } protocol managesieve { } plugin { ... sieve=~/.dovecot.sieve sieve_dir=~/sieve } -- Best regards, Adrian Minta

[Dovecot] Dovecot LMTP - Delivered-To header weirdness
by Daniel Piddock 09 Aug '12

09 Aug '12

Hi, I'm not sure if this is a deliberate design decision or a technical limitation that I've missed. Please briefly explain if so :). Or a bug or feature request? When LMTP receives a mail with a single recipient it adds a Delivered-To header. However if the message is delivered in a batch that header isn't added. At first I thought maybe the LMTP was doing something with hardlinks but that doesn't appear to be the case (for rather obvious reasons.)

[Dovecot] dovecot+LDAP/AD encoding issue
by Wiethoff, Helge 09 Aug '12

09 Aug '12

Hello everybody, i have a problem with dovecot+Active Directory as Authentication-Service. I am not able to use special characters (äöüß (german umlaut)) within a password. Normally I would suggest that the ldap-query is done in UTF-8 but as I debugged the auth-process, I have seen that the password is ISO-8859-1 encoded. The "original" query (from roundcube for example) is UTF-8 encoded (I dumped the POST-Query). So far I wasn't able to find my error by myself or by searching the web. Maybe someone of you can give me a hint :-) Thanks and greetings from Germany, Helge ---- dovecot --version 2.0.16 ---- D-AS01:/etc/dovecot # grep -v '^ *$#.*$\?$' dovecot-ldap.conf.ext uris = ldap://10.37.5.90 dn = CN=ldap-d-as01,CN=Users,DC=tfh-bochum,DC=de dnpass = xxxx auth_bind = yes ldap_version = 3 base = ou=Benutzer, ou=Lehre, dc=tfh-bochum, dc=de user_attrs = =uid=10000,=gid=10000,=home=/srv/mail/%Ld/%Ln user_filter = mail=%u pass_attrs = =uid=10000,=gid=10000,=home=/srv/mail/%Ld/%Ln pass_filter = (&(mail=%u)(!(extensionAttribute3=*))) ---- dovecot -n # 2.0.16: /etc/dovecot/dovecot.conf # OS: Linux 2.6.37.6-0.11-default x86_64 openSUSE 11.4 (x86_64) auth_debug = yes auth_mechanisms = plain login auth_username_translation = %Lu auth_verbose = yes mail_location = maildir:~/Maildir mail_max_userip_connections = 1000 mail_plugins = quota managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace { inbox = yes list = yes location = prefix = INBOX/ separator = / subscriptions = yes type = private } namespace { list = yes location = maildir:%%h/Maildir:INDEX=%h/Maildir/shared/%%u:CONTROL=%h/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = yes type = shared } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/srv/mail/shared-mailboxes quota = maildir:Quota quota_rule = *:storage=1G sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_max_redirects = 10 } protocols = imap pop3 sieve lmtp service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0770 user = root } } service imap-login { process_min_avail = 4 service_count = 0 } service managesieve-login { inet_listener sieve { address = * port = 4190 } inet_listener sieve_deprecated { address = * port = 2000 } process_min_avail = 2 service_count = 0 } ssl_ca = </etc/ssl/certs/tfh_dfn_dtag_cacert.pem ssl_cert = </etc/ssl/certs/imap.stud.tfh-bochum.de-20110530-cert-302177588.pem ssl_key = </etc/ssl/private/imap.stud.tfh-bochum.de-20110530.key userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = quota } protocol imap { mail_plugins = quota acl imap_acl imap_quota } protocol pop3 { mail_plugins = quota } ________________________________ Helge Wiethoff Medienzentrum Telefon: +49 (234) 968 8717 Fax: +49 (234) 968 3453 E-Mail: Wiethoff(a)tfh-bochum.de Technische Fachhochschule Georg Agricola für Rohstoff, Energie und Umwelt zu Bochum Staatlich anerkannte Fachhochschule der DMT-Gesellschaft für Lehre und Bildung mbH Herner Straße 45 44787 Bochum http://www.tfh-bochum.de ________________________________ Träger: DMT-Gesellschaft für Lehre und Bildung mbH Sitz der Gesellschaft: Bochum Registergericht: Amtsgericht Bochum Handelsregister: B 4052 Geschäftsführung: Prof. Dr. Jürgen Kretschmann (Vorsitzender) Manfred Freitag

[Dovecot] Quota dict configuration
by Uros 08 Aug '12

08 Aug '12

Hi, I have enabled quota dict with mysql following wiki http://wiki2.dovecot.org/Quota/Dict Everything work as expected. I just have a question about query used for updating quota usage. I already check the source file dict-sql.c but i still can't figure it out. I store user info in a mysql table where only left (user) part of an email address is stored with foreign id for domain conected to domain table. The problem is administration because quota table have primary key whole email. Is there even possible to configure quota dict settings to use separate variables %n and %d like in user and password query? -- lp Uroš

[Dovecot] dsync and pop3 migration plugin fails for large inbox due to idle timeout
by Nikolai Schupbach 08 Aug '12

08 Aug '12

Timo, There is a problem with the dsync POP3 migration plugin when syncing a large INBOX. What happens is dsync establishes a connection to the POP3 server at the beginning of the sync, but then it sits there idle until it's used to sync the UIDLs. On a very large inbox with many thousands of messages it will be idle for longer than a POP3 server's idle timeout setting. When the UIDL sync occurs dsync produces the following errors (because the connection has been lost due to the POP3 server's inactivity timeout): dsync(first.last(a)test.co.nz): Error: pop3c(pop3.test.com): Server disconnected unexpectedly dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 13: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 15: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 16: Disconnected ... dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14492: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14493: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14494: Disconnected Also at the end of the dsync it actually has an exit status of 0, but it shouldn't because the POP3 sync failed, and none of the UIDLs are retained. Dsync should try to keep the POP3 connection alive, by sending a regular 'NOOP' command to the POP3 server, or it should simply reconnect if sees the connection is lost. At the moment the only work around is to increase the POP3 server's idle timeout to a multi hour value, which isn't a good work around as it causes a lot of inactive POP sessions to bank up. Regards, Nikolai.

[Dovecot] doveadm import is always verbose

Hello, with dovecot versions up to 2.1.9, when I use: doveadm import -u guser mbox:/tmp/mbox/guser/restore_2012-05-08 restore_2012-05-08 all it always sends out info messages for every mail copied like that: doveadm(guser): Info: copy from mymail: box=restore_2012-05-08/mymail, uid=5, msgid=<######>, size=6999462 I had expected to see these info messages only if I add the verbose option to doveadm. And using the option -v with: doveadm -v import -u guser mbox:/tmp/mbox/guser/restore_2012-05-08 restore_2012-05-08 all makes no difference at all, the same messages appear. The verbose option seems to be always on. Is this a bug or intended behaviour?

[Dovecot] Dovecot with Company - level Quota
by Kavish Karkera 08 Aug '12

08 Aug '12

Hi Timo, We are using maildir as quota-backend , and performing user level quota, which is working fine. (using dovecot 2.x ). Now the requirement is to , restrict the quota to client / company level along with user level quota. For. eg. We have a mailbox path like /mail/mailstore/10001/kavish.karkera(a)linoquery.com/Maildir/ where 10001 is Client code (unique number given to very client) instead of domain name. So there would be two quota's one at company level and other user level. Such as 10001(linoquery.com) = 5GB ---> Company Quota kavish.karkera(a)linoquery.com = 0 ? ---> User Quota If the sum of the user quota under 10001/* exceeds the 5GB limit then the mails for that particular domain should get bounced. Please Help , if this is possible. Regards, Kavish Karkera

[Dovecot] replication chain

good day! I wonder if it is possible to make a chain of replication in dovecot 2.1.9. Now I'm using two way replication(I use proxy to redirect users) and it's working just fine but is it possible to setup replication like this: serverA ---> serverB --> server C <--- I've added additional mail_replica2 on serverB and after restart dovecot didn't complain about errors, with doveconf -n I am able to see two replica's settings but user's mails aren't replicating to server C. no errors in logs. I want to use server C as backup server with lvm snapshots.

Do the same user(s) have this problem and/or do each user have their own mail configuration for their mail readers? If yes, I would also check that the port and security protocol matches (i.e. clear/TLS/SSL on ports 110/110/995 respectively). Mismatched configurations could cause what you describe.

Re: [Dovecot] redirect actions exceeds policy limit

Thank you David, I saw that in the share/docs but we didn't have the /conf.d/ folder or any of the extra conf files in place. I created that directory, copied the file over, made my changes and all is well again. Not sure why things were setup the way they were, after looking at the other files in conf.d it would appear the previous sysadmin had merged a lot of those bits and pieces into the main dovecot.conf file.

[Dovecot] Pigeonhole sieve include namespace regression

07 Aug '12

Hi, We've recently upgraded from Dovecot 1.2.15 with Sieve 0.1.18 (Debian Squeeze) to Dovecot 2.1.8 and Pigeonhole 0.3.1. We provide a selection of global sieve scripts to make users' lives easier and one noticed that some of these have stopped working. I tracked it down to them having personal scripts with the same name. Using a really simple sieve script: require "include"; include :personal "svn"; include :global "svn"; sievec debug output for sieve 0.1.18 (trimmed a bit): * Required extensions: 0: include (16) 1: fileinto (5) * Included personal script 'svn' (block: 3): [script code here] * Included global script 'svn' (block: 4): [script code here] * Main program (block: 1): 00000000: EXTENSIONS [1]: 00000001: include 00000002: INCLUDE: 00000004: script: svn.sieve [ID: 1, BLOCK: 3] 00000006: INCLUDE: 00000008: script: svn.sieve [ID: 2, BLOCK: 4] 0000000a: [End of code] sievec debug output for Pigeonhole 0.3.1: * Required extensions (block: 1): 0: include (id: 16; block: 4) 1: fileinto (id: 5) * Included personal script 'svn' (block: 5): [script code here] * Main program (block: 2): Address Line Code 00000000: DEBUG BLOCK: 3 00000001: EXTENSIONS [1]: 00000002: include 00000003: 2: INCLUDE: 00000005: script: `svn' from /home/notroot/sieve/svn.sieve [ID: 1, BLOCK: 5] 00000007: 3: INCLUDE: 00000009: script: `svn' from /home/notroot/sieve/svn.sieve [ID: 1, BLOCK: 5] 0000000b: 3: [End of code] As can be seen the personal script is included twice.

[Dovecot] connectionlimit for pop3s?
by Hajo Locke 07 Aug '12

07 Aug '12

Hello, i have a user who is able to do pop3 on port 110 without problems and without limits. There are ~10 real users using same public IP. When switching to port 995 to use pop3s he is limited at connection count. Some people can reach pop3s-server successful, some getting a timeout. I cant find any errors or limits within my config or in my log, there are no differences between using plain text and using tls. Are there some special loglines to grep for at this situation? Maybe i missed some lines... At the moment i dont see server-side problems. Somebody knows some typical clientside problems when this problem occurs? dovecot version is 1.2.11 Thanks, Hajo

[Dovecot] redirect actions exceeds policy limit
by Mike Greene 06 Aug '12

06 Aug '12

Hello, We have a vacation/mail forwarder plugin in squirrel mail that allows customers to forward email. It has come to my attention that there is a limit (appears to be 5) on the number of addresses that can be specified. I'm now trying to track down where this policy limit is set. This is the error we see in the customers .dovecot.sieve.log file: main_script: line 26: error: number of redirect actions exceeds policy limit. sieve: info: started log at Jul 25 07:02:54. I checked the following for possible settings: /usr/local/etc/dovecot/dovecot.conf /usr/local/etc/sieve/dovecot.sieve /usr/local/etc/sieve/global.sieve I didn't see anything specific to limiting the number of redirects. I'm wondering where else I can look to find where this limit is coming from and adjust it upwards. We are using the following dovecot / pigeonhole versions. dovecot-2.0.7 dovecot-pigeonhole-0.2.1 athena# dovecot -n # 2.0.7: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.1-RELEASE amd64 auth_default_realm = rockisland.com auth_mechanisms = plain login cram-md5 auth_username_format = %Lu disable_plaintext_auth = no dotlock_use_excl = yes first_valid_gid = 1000 first_valid_uid = 1000 listen = * mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_privileged_group = mail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf driver = ldap } plugin { quota = maildir quota_rule = *:storage=2G quota_warning = storage=90%% /usr/local/sbin/quota-warning.sh 90 quota_warning2 = storage=80%% /usr/local/sbin/quota-warning.sh 80 sieve = ~/.dovecot.sieve sieve_dir = ~/ sieve_global_dir = /usr/local/etc/sieve/ } protocols = imap pop3 service auth { unix_listener auth-client { mode = 0660 } unix_listener auth-master { group = vmail mode = 0600 user = vmail } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } user = root } service imap-login { service_count = 0 } service pop3-login { service_count = 0 } ssl_cert = </usr/local/etc/ssl/star.rockisland.com.crt.pem ssl_key = </usr/local/etc/ssl/star.rockisland.com.key.pem userdb { driver = prefetch } userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf driver = ldap } verbose_proctitle = yes protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol lda { auth_socket_path = /var/run/dovecot/auth-master info_log_path = lda_mailbox_autocreate = no lda_mailbox_autosubscribe = yes log_path = mail_plugins = quota sieve postmaster_address = postmaster(a)rockisland.com sendmail_path = /usr/sbin/sendmail } Mike Greene Rock Island Technology Solutions, Inc.

I'm trying to setup per user '+spam' delivery from amavis tags, so that each user gets any mails tagged as spam to 'spam' Maildir via +spam Dovecot lmtp delivery. after say 7 days I want to delete all spams older than 7 days, if I simply delete mail files from the file system, is that a 'bad thing' ? what is a proper way to do that, and scripts ? for removing/archiving old uncollected emails in main INBOX I use archivemail from sf, but, don't think I can do subfoldrs with archivemail any pointers (and scripts) welcomed, thanks -- Voytek

[Dovecot] authenticate plain and utf-8 with special chars
by Matthias Lay 04 Aug '12

04 Aug '12

Hi, I experienced some problems with authenticate. seems like the mail clients like thunderbird send their base64 string in ISO- encoding, which doesnt work on my dovecot setup if there are some Umlauts I am not able to login as "ömer" for example If I authenticate from telnet with an base64 encoded utf-8 string like 'echo -en "\0ömer\0Start12" |base64' everything works fine -dovecot 2.1.7 -userdb is an openldap which queries an windows AD so results are in utf8, I think. any clues at which point to fix this are welcome ;)

[Dovecot] Overriding inbox= in userdb extra fields
by Bret Martin 03 Aug '12

03 Aug '12

Hello, I'm trying to set up an alternate user with a different inbox using passwd-file and userdb extra fields and the extra field settings don't seem to be taking effect. I've used auth_debug and mail_debug and I'm unclear how I can further troubleshoot this. Is it possible to have inbox=yes in one namespace globally and then override this for one user by setting inbox=no for that namespace and then inbox=yes for another? My doveconf -n is below. I would like to have inbox=yes for the inbox namespace, inbox=no for the virtual namespace, and then be able to invert these for selected users using userdb extra fields. My attempt at doing this so far looks like bam-ios:[REDACTED]:500:500::/home/bam::user=bam namespace/inbox/inbox=no namespace/virtual/inbox=yes Changing the user with user= seems to work fine, but the inbox= changes don't.

[Dovecot] v2.1.9 released
by Timo Sirainen 03 Aug '12

03 Aug '12

http://dovecot.org/releases/2.1/dovecot-2.1.9.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.9.tar.gz.sig I've again mostly finished reading and answering most of the mails in Dovecot mailing list. There are a couple annoyingly difficult / time consuming bugreport mails that I haven't replied to yet, but if anyone thinks I should have replied to something already feel free to resend the mail. For the new Redis/memcached dict stuff see http://master.wiki2.dovecot.org/AuthDatabase/Dict and http://master.wiki2.dovecot.org/Quota/Dict I'm thinking about removing the new quota_ignore_save_errors=yes setting in v2.2 and just forcing it enabled always. Thoughts? (I didn't want to change v2.1 behavior by doing this.) The most important changes since v2.1.8: * mail-log plugin: Log mailbox names with UTF-8 everywhere (instead of mUTF-7 in some places and UTF-8 in other places) * director: Changed director_username_hash setting's default from %u to %Lu (= lowercase usernames). This doesn't break any existing installations, but might fix some of them. + doveadm: Added "auth cache flush [<username>]" command. + Implemented dict passdb/userdb + Implemented Redis and memcached dict backends, which can be used as auth backends. Redis can also be used as dict-quota backend. + Added plugin { quota_ignore_save_errors=yes } setting to allow saving a mail when quota lookup fails with temporary failure. - Full text search indexing might have failed for some messages, always causing indexer-worker process to run out of memory. - fts-lucene: Fixed handling SEARCH HEADER FROM/TO/SUBJECT/CC/BCC when the header wasn't lowercased. - fts-squat: Fixed crash when searching a virtual mailbox. - pop3: Fixed assert crash when doing UIDL on empty mailbox on some setups. - auth: GSSAPI RFC compliancy and error handling fixes. - Various fixes related to handling shared namespaces

[Dovecot] Antispam only when LMTP delivers some specific messages
by Sandro Tosi 03 Aug '12

03 Aug '12

Hello, we're setting up a weird platform where every incoming email is passed from the MTA directly to a tool that then uses dovecot LMTP to deliver the message into the user mailbox. We are legally *not* allowed to run antispam on all the incoming messages, but only on some of them, as they are recognized by the aforementioned tool; but given that tool directly uses LMTP to delivers the mail we need to find a way to parse the messages passing thru LMTP and run spamassassin only on those matching some regex on subject and mail body. Is is possible to do that with some dovecot LMTP feature? i've read a lot of documentation about how to possibly implement it and it *seems* there would be a way using pigeonhole sieve and extprograms - what do you think? The idea I have in mind is something like: 1. identify the mails we want to scan with spamassassin (using regex or whatever else to precisely pin-point them) 2. run SA on those 3. in case it's spam, rewrite the subject (or similar) Do you think it's something doable with dovecot? Thanks in advance, -- Sandro Tosi Product Engineer Shared Hosting Products R&D | Dada.pro eml sandro.tosi(a)register.it

The problem is that it dosn't update the quota rules in Maildir when quota is changed in userdb. I have the rules avaiable in qmail-lda's environment, but I need an idea on how to feed the quota rule string to quota plugin without doing userdb lookup. What whould be the best way to do this, maybe in plugins/quota/quota.c:quota_root_add_rules() ? Regards, Michal Grzedzicki

hello I see this message in the dovecot error log every time a user connect to IMAP service. imap(xxxxxxxx): Error: opendir(/user/xxxxxxxx/.imap) failed: No such file or directory In the server's config I've this mail_location = mbox:%h/:INBOX=/var/mail/%u:INDEX=/var/spool/dovecot/index/%u As we can see INDEX files are not living in user's home directories but in /var/spool/dovecot/index/%u so why this error message ?

[Dovecot] Problem with preserving MIME format with Dovecot IMAP and MS Outlook client
by Peter Grimmond 01 Aug '12

01 Aug '12

Hello all, Apologies for the repost, but I am really struggling to solve this problem... I have installed Dovecot 2.0.19 on Ubuntu 12.04 LTS. I have set up a very basic IMAP configuration. I have two different laptops running MS Outlook (one MacOS, one Windows 7) and I have configured both to connect to the Dovecot service. My problem is, emails in MIME format that I synchronise from one MS Outlook client are not being correctly decoded as MIME messages on the other client. Instead, the message is rendered in plaintext, starting with the lines: This message is in MIME format. Since your mail reader does not understand this format, some or all of this message may not be legible. --B_3426360453_22814Content-type: multipart/alternative; boundary="B_3426360453_4099" --B_3426360453_4099Content-type: text/plain; charset="ISO-8859-1"Content-transfer-encoding: quoted-printable Can anyone help me understand why this might be happening? The output from dovecot -n is: # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-26-generic-pae i686 Ubuntu 12.04 LTS auth_debug = yes auth_verbose = yes disable_plaintext_auth = no mail_location = maildir:~/Maildir passdb { driver = pam } protocols = " imap" ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } Thanks!

[Dovecot] Erroneous operation not permitted when deleting mailbox with mdbox
by Nikolai Schupbach 01 Aug '12

01 Aug '12

I'm seeing the following error in our logs when removing mailboxes (we are using mdbox and dovecot 2.1.8): Aug 1 20:03:36 msgsrv dovecot: imap(test(a)test.com): Error: stat(/mailstore/domains/test.com/test/mdbox/mailboxes/Spam) failed: Operation not permitted Aug 1 20:03:36 msgsrv dovecot: imap(test(a)test.com): Mailbox deleted: Spam When I run truss against the process it appears the error relates to attempted unlink of a directory, not a stat of it, as reported by the log. However the mailbox does appear to be deleted fine, so it appears to be an erroneous error.

[Dovecot] BUG: LDAP extension failed to authenticate if 'base' DN configuration is empty ''
by Hendy Irawan 01 Aug '12

01 Aug '12

Dear Dovecot developers, We have several context entries and want to authenticate a user against the whole LDAP server. However when setting "base = " Dovecot LDAP fails with following message: Jul 29 10:50:59 nitik1 dovecot: auth: Error: ldap(hendy(a)staging.member.berbatik.com,127.0.0.1): ldap_search((virtualMail=hendy(a)staging.member.berbatik.com)) failed: Other (e.g., implementation specific) error This limits the search to only one base DN, e.g. base = dc=staging,dc=berbatik,dc=com The ldap client library is able to search entries using an empty base DN, so it should be possible for Dovecot LDAP to do the same. An even more elegant solution will be the ability to specify multiple base DNs, but if Dovecot can search the "root DN" (empty string) it would be great. Thank you.

[Dovecot] mdbox with separate index location results in many emptydirectories
by Jürgen Obermann 31 Jul '12

31 Jul '12

Hallo, I use dovecot 2.1.7 with mdbox format and I specified a separate location for mailbox index files with mail_location = mdbox:/dovecot/storage%h:INDEX=/dovecot/index%h With this setting I get for every mailbox a directory under both filesystems /dovecot/index and /dovecot/storage, e.g. for the inbox it looks like that: # ls -lR /dovecot/index/home/hrz/myuser/mailboxes/INBOX /dovecot/storage/home/hrz/myuser/mailboxes/INBOX /dovecot/index/home/hrz/myuser/mailboxes/INBOX: total 49 -rw------- 1 myuser hrz 20480 Jul 20 11:12 dovecot.index.cache -rw------- 1 myuser hrz 1280 Jul 20 08:00 dovecot.index.log -rw------- 1 myuser hrz 301 Jul 19 16:45 dovecot.index.search -rw------- 1 myuser hrz 20 Jul 19 16:45 dovecot.index.search.uids /dovecot/storage/home/hrz/myuser/mailboxes/INBOX: total 3 drwx------ 2 myuser hrz 2 Jul 19 15:20 dbox-Mails /dovecot/storage/home/hrz/myuser/mailboxes/INBOX/dbox-Mails: total 0 As expected the index files now reside under /dovecot/index%h/mailboxes/, but the path /dovecot/storage%h/mailboxes/ also contains for every user and every mailbox name a directory which in turn contains only an empty subdirectory 'dbox-Mails'. These directories seem to me to sum up to a lot of unneded infrstructure objects. I tried to delete these empty directories, but dovecot did not like that and stopped to work. So somehow they are necessary, in spite of setting a separate index file location. So my question is, could these empty directories be avoided, perhaps in a future version?

[Dovecot] Empty argument in "executable = script ..." service
by Florian Wagner 31 Jul '12

31 Jul '12

Hi, what is the point of adding an empty argument to the command called by the "executable = script ..." setting in a service? I guess that would be the call to array_append_space at line 57 in util/script.c. Background is that I'm trying to run bogofilter through the extprograms Pigeonhole plugin. So I've defined a service entry with a unix_listener and wondered why my test shell script works but bogofilter exits with a cryptic error. Turns out that this empty argument at the end trips up the bogofilter argument parsing code. If I manually call bogofilter with execv and add that empty argument I get the same cryptic error. Regards Florian

[Dovecot] Dovecot Director behaviour when two or more fail
by Dominic Malolepszy 31 Jul '12

31 Jul '12

Hi, On the Dovecot wiki here http://wiki2.dovecot.org/Director it says the following: "The directors are going to connect to each others in a ring. For example if you have servers called A, B and C, director will create connections A->B, B->C and C->A" I am curious what happens in a scenario when two or more directors fail and potentially break a ring in half, do the active directors detect this and reform a new ring?

[Dovecot] Help needed with configuration giving dict error No such file

Each time a mail message is delivered to a mailbox records like the following appear in /var/log/dovecot.warn: Jul 29 10:02:05 iris dovecot: lmtp(29320, jax(a)XXX.com) Error: file dict commit: file_dotlock_open(/var/vmail/XXX.com/jax/home/maildir/dovecot-quota) failed: No such file or directory Jul 29 10:02:05 iris dovecot: lmtp(29320, jax(a)XXX.com) Error: file dict commit: file_dotlock_open(/var/vmail/XXX.com/jax/home/maildir/dovecot-quota) failed: No such file or directory Jul 29 10:02:05 iris dovecot: lmtp(29320, jax(a)XXX.com) Error: dict quota: Quota update failed, it's now desynced This is with Dovecot 2.1.7 installed by Debian Squeeze binary packages, dovecot-core v 1:2.1.7-2~bpo60+1, and friends. The host is running GNU/Linux 3.2.0-0.bpo.2-amd64 and on a xfs filesystem. Entries in /etc/dovecot/users look like this: jax@XXX.com:{plain}password The output from 'doveconf -n' is in the attachment to this mail message. I'm a beginner without experience with either IMAP servers or clients. Can you give me pointers to see what I'm missing that causes the errors logged as above? The user data base looks like this: userdb { args = uid=5000 gid=5000 home=/var/vmail/%d/%n/home mail=maildir:/var/vmail/%d/%n driver = static } Being a beginner, I wonder if is necessary to manually make home directories for each '/var/vmail/%d/%n/home'? I've tried test accounts with and without empty "home" directories at the indicated locations without seeing any difference in the error indications. Is it necessary to manually populate the "home" directories? Besides having no clue about the errors logged, I don't understand what it takes to make quotas work nor do I understand what options are available or advisable. The distribution wiki/QuotaMaildir.txt seems clear that the Maildif+++ backend is indicated but beyond that I remain in the dark. FWIW, I've yet to try a real IMAP client. Thank you for any pointers you can give me.

[Dovecot] Problem with running two dovecot instances on the same server
by Alexandr Sabitov 31 Jul '12

31 Jul '12

Hello All, Have anyone met the problem I am struggling with at the moment ? The problem is when I run two instances of dovecot 2.1.8 which are one for proxy-director and another one is a regular one on the same server then I have big amount of strange entries in the /var/log/mail.err: Jul 26 11:51:20 dovecot-test-1 dovecot: director: Error: Empty server list Jul 26 11:51:20 dovecot-test-1 dovecot: director: Fatal: Invalid value for director_mail_servers setting Jul 26 11:51:20 dovecot-test-1 dovecot: master: Error: service(director): command startup failed, throttling for 60 secs Jul 26 11:52:20 dovecot-test-1 dovecot: director: Error: Empty server list Jul 26 11:52:20 dovecot-test-1 dovecot: director: Fatal: Invalid value for director_mail_servers setting Jul 26 11:52:20 dovecot-test-1 dovecot: master: Error: service(director): command startup failed, throttling for 60 secs That's for sure set->director_mail_servers variable in main_preinit of ./src/director/main.c But after dumping it it turns out that ppid of the process which failed to use main_preinit function is a "regular" dovecot not the proxy one. When main_preinit is used by dovecot-proxy then set->director_mail_servers = ip address of a mail server and it is all good but if main_preinit is used by dovecot then set->director_mail_servers = empty and I get fatal errors in logs. So here is a question: How come that "non-proxy" dovecot requests director_mail_servers variable and writes fatal error in the logs if it doesn't find it ? Thank you very much for any assistance!

[Dovecot] maildir_copy_with_hardlinks on v.2.0.19
by mailing list subscriber 31 Jul '12

31 Jul '12

Hi, I'm trying to get the so-called "single instance store" (I think cyrus has got the name for the first time) with dovecot --version = 2.0.19 binary package installed from ubuntu 12.04 lts official repo. I have checked that "maildir_copy_with_hardlinks" is enabled ("dovecot -a|grep hard" shows "yes") then I have installed and enabled the lmtp component of dovecot. The configuration "dovecot -n" is pasted here: http://paste.lug.ro/131180 Also in the same paste is a strace against dovecot and childrent showing evidence of the MTA delivering a single copy of the message via LMTP with multiple RCPT TO: headers. However when looking in the Maildir, I see the mail break down into three separate files instead of expected hardlinked files ("stat" and "ls" shows one single link count, inodes are different) Given the above data, what (am I | dovecot is) doing wrong? Please cc me if you need additional input when replying as I'm not subscribed to the list (I'll watch the thread online only) Many thanks in advance.

Evolution seems to be in pretty widespread > use. Wondering what others like and use heavily. Hi Chris, I tried Evolution once about 10 years ago, and it was too complex and comprehensive for me to understand. The centerpiece of my emailing activity is a Dovecot IMAP server on my daily driver desktop computer. The way it works is that fetchmail grabs all my email from my various POP accounts, pushes them through procmail, whose filters distribute the emails into the proper Dovecot IMAP directories (and also /dev/null stuff from PITA people). As far as I know, my Dovecot has never malfunctioned. Currently, I access my local IMAP with Claws-Mail. Claws is capable, robust, and does what I need without being an ecological disaster like Kmail or intermittently pig slow like Thunderbird. Claws' configuration is difficult to wrap your head around, and very much in need of better documentation, but so far, thanks to a knowledgeable and helpful user community on the mailing list, I've been able to make almost every config change to speed my interaction with Claws. My one complaint about Claws that can't be cured by documentation is its propensity to do everything with one process and one thread, so while you're sending an email or scanning your IMAP, you cannot look at other emails. I also wanted their powerful search to be able to recurse folders, and when nobody volunteered to do it, I tried to do it myself. Making something recursive sounds like simply a matter of writing a simple loop around the existing functionality, but what I found out is, at least this part of Claws was written in a manner resembling MVC, with process and UI completely commingled. For that reason I was unable to make it recursive. I have Claws on my daily driver and all my laptops. Thanks to Kevin Korb's instructions, on the laptops I was able to tell Claws its IMAP server was at 127.0.0.1. I pinholed my OpenBSD/pf firewall appliance to port forward incoming ssh to my daily driver. Then, on my laptop, if I'm at home and on the LAN, I run the following inhouse.sh sudo ssh -NTL 993:127.0.0.1:993 slitt(a)192.168.1.88 While on the road I run this travelling.sh: sudo ssh -NTL 993:127.0.0.1:993 slitt(a)99.99.99.99 In the preceding, 99.99.99.99 is the IP address my ISP gave me, while 192.168.1.88 is the LAN IP address of my daily driver. This makes 127.0.0.1:993 get pushed through ssh to the ISP supplied internet address or the LAN address. So I can use Claws to interact with my daily driver desktop anywhere I go. I'm extremely pleased with this setup. My IMAP tree is trivial to back up, and gives me the assurance that if Claws-Mail ever commits suicide the way Kmail did when they went to Kmail2, I can simply plug in a different IMAP enabled email client. Meanwhile, Claws gives me an extremely productive and easy to use user interface. With my client/server setup, I no longer need to copy all my email too and from the laptop when travelling. I'm going to present on my remote use of my daily driver desktop Dovecot, using Claws and ssh, at tomorrow night's GoLUG meeting.

[Dovecot] Address extensions

Hi guys, I'm trying to set up in-mailbox routing for messages using the + delimiter. The server runs postfix and dovecot 1.2.15. I have re-defined the delivery service in master.cf as "-f ${sender} -d ${user}@${nexthop} -n -m INBOX.${extension}" (server was formerly courier) but the routing only works when the destination folder has no uppercase characters. "Folder1" doesn't deliver correctly while "folder2" does. What am I doing wrong? Kurt

[Dovecot] SSL Warnings in Debug Logs

Greetings, In doing some debugging of authentication issues, I'm wondering if these SSL warnings are anything to be investigating?

[Dovecot] mysql auth failover failing
by Paul B. Henson 29 Jul '12

29 Jul '12

We are running dovecot to provide authentication for postfix, using two mysql servers in a multi-master replication set as the password source: ---------------------------------------- # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.37-gentoo-r4 x86_64 Gentoo Base System release 2.0.2 auth_mechanisms = plain login digest-md5 cram-md5 auth_verbose = yes passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocols = none service auth-worker { unix_listener auth-worker { user = postfix } user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = postfix } ssl = no userdb { driver = passwd } --------------------------------------- With an sql config of: ------------------------- driver = mysql connect = host=mysql-1.unx.csupomona.edu host=mysql-2.unx.csupomona.edu dbname=idmgmt user=postfix password=XXXXXXX default_pass_scheme = PLAIN password_query = XXXXXXXXX ------------------------- According to the sample SQL configuration file "HA / round-robin load-balancing is supported by giving multiple host settings, like: host=sql1.host.org host=sql2.host.org". However, as far as I can tell dovecot only connects to the first listed host, and processes all queries through it, there does not appear to be any load-balancing going on. That's not necessarily a dealbreaker; however, high-availability does not appear to be working either. If I shutdown the first mysql server, dovecot starts to log connection failures: Sep 9 15:47:34 tweak dovecot: auth: Error: mysql(mysql-1.unx.csupomona.edu): Connect failed to database (idmgmt): Can't connect to MySQL server on 'mysql-1.unx.csupomona.edu' (111) - waiting for 1 seconds before retry Sep 9 15:47:39 tweak dovecot: auth: Error: mysql(mysql-1.unx.csupomona.edu): Connect failed to database (idmgmt): Can't connect to MySQL server on 'mysql-1.unx.csupomona.edu' (111) - waiting for 25 seconds before retry And postfix starts to fail authentications: Sep 9 15:47:35 tweak postfix/smtpd[5119]: warning: bender.iitsys.csupomona.edu[134.71.250.134]: SASL DIGEST-MD5 authentication failed: Connection lost to authentication server Now and again the authentication process dies: Sep 9 15:47:39 tweak dovecot: auth: Panic: file auth-request-handler.c: line 697 (auth_request_handler_flush_failures): assertion failed: (auth_request->state == AUTH_REQUEST_STATE_FINISHED) Sep 9 15:47:39 tweak dovecot: auth: Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x3f71a) [0x7f25822ca71a] -> /usr/lib64/dovecot/libdovecot.so.0(+0x3f766) [0x7f25822ca766] -> /usr/lib64/dovecot/libdovecot.so.0(+0x198ca) [0x7f25822a48ca] -> dovecot/auth() [0x4137f4] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handle_timeouts+0xd4) [0x7f25822d5fe4] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x5b) [0x7f25822d6bcb] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7f25822d5c48] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f25822c3de3] -> dovecot/auth(main+0x2be) [0x4179de] -> /lib64/libc.so.6(__libc_start_main+0xfd) [0x7f2581898bbd] -> dovecot/auth() [0x40bdc9] Sep 9 15:47:39 tweak dovecot: master: Error: service(auth): child 4154 killed with signal 6 (core dumps disabled) Requests start to pile up: Sep 9 15:51:46 tweak dovecot: auth: Warning: auth workers: Auth request was queued for 25 seconds, 45 left in queue Lookups time out: Sep 9 15:57:22 tweak dovecot: auth: Error: auth worker: Aborted request: Lookup timed out This occasionally pops up: Sep 9 15:58:38 tweak dovecot: auth: Fatal: net_connect_unix(auth-worker) failed: Resource temporarily unavailable And sometimes the auth process gets temporarily disabled: Sep 9 15:58:57 tweak dovecot: master: Error: service(auth): command startup failed, throttling Resulting in more postfix authentication failures: Sep 9 15:58:57 tweak postfix/smtpd[6531]: warning: bender.iitsys.csupomona.edu[134.71.250.134]: SASL DIGEST-MD5 authentication failed: Sep 9 15:59:08 tweak postfix/smtpd[6551]: fatal: no SASL authentication mechanisms To the point where postfix also temporarily throttles smtpd: Sep 9 15:59:21 tweak postfix/master[6526]: warning: /usr/lib64/postfix/smtpd: bad command startup -- throttling Resulting in a complete unavailability of smtp service, not just unavailability of authenticated services. I don't think all authentications fail during the scenario, but I think the majority do. Based on the network traffic, dovecot is almost continuously trying to connect to the first listed server. It sometimes connects to the second listed server, but when it does, the connection does not persist, it goes away almost immediately. Ideally, I would like no authentications to fail if one of the MySQL servers is unavailable. If a few fail just when the server dies, that would be undesirable but acceptable as long as they do not continuously fail while the server is down. Am I doing something wrong? Does the example sql config have incorrect information? We were previously running dovecot 1.2.11, we just recently upgraded to 2. In the previous version, we actually had two different passdb's configured, each one listing only one of the mysql servers. I seem to recall that was the recommendation at the time for high-availability. When that configuration did not seem to work under version 2, I found an updated recommendation to list both servers in the same passdb, which also does not appear to work correctly. I actually went back and tested the older version, and determined it seemed to work okay in the case where the server was up but the service was down, and connections were refused, but also failed a large number of authentication attempts when the server was completely down and connections were timing out.

[Dovecot] Enable ACL for master user
by punit_j 29 Jul '12

Hi Team, I have dovecot setup and I have enabled master User login in dovecot.conf file as below :- auth_master_user_separator = * passdb { driver = passwd-file args = /etc/dovecot/passwd.masterusers master = yes pass = yes } passdb { driver = shadow } userdb { driver = passwd } and craeted file. I can login to the user but what I see after login is : - Trying 0.0.0.0... Connected to 0. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 STARTTLS AUTH=PLAIN] Dovecot ready. a login user*masteruser password a OK Logged in. a list "" * * LIST (\HasNoChildren) "." "Trash" * LIST (\Unmarked) "." "INBOX" a OK List completed. However when I login as a normal user I see this : - Connected to 0. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 STARTTLS AUTH=PLAIN] Dovecot ready. a login user userpassword a OK Logged in. a list "" * * LIST (\HasNoChildren) "." "Drafts" * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Sent items" * LIST (\HasNoChildren) "." "INBOX" a OK List completed. I think its because of ACL for user and it is using masterusers ACL. I looked at http://wiki2.dovecot.org/PostLoginScripting, however do we have sample login script so that I can use that script with modifications. Sorry I am new to dovecot. Thanks and Regards.

[Dovecot] lmtp log message

I just tried switching to lmtp from lda. Messages are being delivered, but I now see messages similar to: Jul 26 22:59:21 bubba dovecot: lmtp(20508): Disconnect from local: Client quit (in reset) in my log for every message. Is this a normal sign-off - or does this indicate a misconfiguration? -- Daniel

[Dovecot] Problem with preserving MIME format with Dovecot IMAP and Outlook
by Peter Grimmond 29 Jul '12

29 Jul '12

Hello, I have installed Dovecot 2.0.19 on Ubuntu 12.04 LTS. I have set up a very basic IMAP configuration. I have two different laptops running Outlook (one MacOS, one Windows 7) and I have configured both to connect to the Dovecot service. My problem is, emails in MIME format that I synchronise from one Outlook client are not being correctly decoded as MIME messages on the other client. Instead, the message is rendered in plaintext, starting with the lines: This message is in MIME format. Since your mail reader does not understandthis format, some or all of this message may not be legible. --B_3426360453_22814Content-type: multipart/alternative; boundary="B_3426360453_4099" --B_3426360453_4099Content-type: text/plain; charset="ISO-8859-1"Content-transfer-encoding: quoted-printable Can anyone help me understand why this might be happening? The output from dovecot -n is: # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-26-generic-pae i686 Ubuntu 12.04 LTS auth_debug = yes auth_verbose = yes disable_plaintext_auth = no mail_location = maildir:~/Maildir passdb { driver = pam } protocols = " imap" ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } Thanks!

Re: [Dovecot] expire-tool stops on first box with nothing to expire in it

Michael Wessel writes: > When I run for example: > > doveadm -D search -A mailbox Trash savedbefore 60d > /tmp/discard I previously observed that the "date.saved" field (tested by savedbefore) seems to be clustered around particular timestamps. Dumping out this field using doveadm -ftab fetch -A \ "mailbox date.saved" \ $ mailbox Trash OR mailbox Junk OR mailbox "Deleted Items" $ it seems the timestamps do not actually correspond to when the client moves messages to their trash folder, but rather, to the time I query for it i.e. a query instantiates this value. This timestamp is then retained. In practice, if this query is done on a periodic interval (e.g. daily), the date.saved will be roughly correct, and is usable as an age test for expungement. Is there a way to force this value to be cached when the client actually saves or moves a message? Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] [PATCH] Pop3/imap ordering in courier-dovecot-migrate.pl
by Pavel Stano 28 Jul '12

28 Jul '12

Hi, current version of courier migration script courier-dovecot-migrate.pl preserve order of POP3 UIDLs, but it keep IMAP UIDs not in order which cause problems with clients using IMAP along with POP3 in some cases. Attached patch use MAIL_FETCH_POP3_ORDER feature added in version 2.0.13 to keep POP3 and IMAP UID[L]s in order. -- [ Ohodnotte kvalitu mailu: http://nicereply.com/websupport/4afafd34/ ] Pavel Stano | admin team http://WebSupport.sk *** TAKE AND ENJOY ***

[Dovecot] Dsync replication
by list＠airstreamcomm.net 28 Jul '12

28 Jul '12

I have been loosely following discussions dsync replication, but I am wondering if this tool still in a testing phase or has it been committed as a production part of Dovecot? I would like to do some testing with the protocol to see if it's capable of handling the change rate our mail service generates, which has about 23,000 active users. We are trying to find solutions for a two site setup where mail processing is either being done at the primary data center A and fails over to a hot standby cluster at the secondary data center B, or where both data centers are doing active processing. I have been unable to find documentation on dsync replication on the wiki, so if there is any documentation available on how to setup dsync replication I would appreciate a nudge in the right direction.

Hello. This is in Dovecot 2.1.7 on Linux x86, but it looks as though 2.1.8 has the same issue. I'm using fts-lucene. SEARCH HEADER TO returns no results, but SEARCH TO works: B SEARCH TO TEST * SEARCH 1 2 3 4 5 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 24 26 27 28 29 31 B OK Search completed (0.000 secs). C SEARCH HEADER TO TEST * SEARCH C OK Search completed (0.000 secs). Without FTS enabled, both forms of the query work. It looks as though the header names are indexed in lower case. But Dovecot is passing the header name to the backend in upper case when SEARCH HEADER is used. I'm not sure whether this is the *right* fix, but lower-casing the header name in lucene-wrapper.cc seems to fix the problem: --- dovecot-2.1.7-clean/src/plugins/fts-lucene/lucene-wrapper.cc 2011-12-13 06:35:29.000000000 -0500 +++ dovecot-2.1.7/src/plugins/fts-lucene/lucene-wrapper.cc 2012-07-24 14:03:14.000000000 -0400 @@ -1094,7 +1094,7 @@ return false; q = lucene_get_query(index, - t_lucene_utf8_to_tchar(index, arg->hdr_field_name, FALSE), + t_lucene_utf8_to_tchar(index, t_str_lcase(arg->hdr_field_name), FALSE), arg); break; default: Now: B SEARCH TO TEST * SEARCH 1 2 3 4 5 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 24 26 27 28 29 31 B OK Search completed (0.000 secs).

[Dovecot] Auto logging-out client
by Nicolás 28 Jul '12

28 Jul '12

Hi list! I'm writing because of an issue I'm having with my Postfix-Dovecot installation. Everything's working fine but when an IMAP client is idle for some time, Dovecot automatically logs it out. Jul 26 14:01:16 mail dovecot: imap(nicolas(a)devels.es): Disconnected: Logged out bytes=1271/7439 This entails errors when trying to send e-mails after this auto logout, such as: host devels.es[91.215.158.237] said: 550-Please turn on SMTP Authentication in your mail client, or login to the 550-IMAP/POP3 server before sending your message. Which result in a very annoying and continuous proccess of restarting my mail client. Is there a way to avoid this auto-logout, or at least configure the time after I want idle clients to auto-logout? Thank you very much! Nicolás

[Dovecot] Slightly OT - Winbind and remote authentication.
by Simon Brereton 28 Jul '12

28 Jul '12

Hi I was doing some research on setting up a samba server for my internal network (as an alternative to NAS). The setup looks easy enough, but then I got to thinking - I already have an internet host with an mysql DB that has usernames and passwords and it would be simpler all round to reuse that as the authentication server. That server is also running Dovecot, so I thought it might be simpler still to set up samba to authenticate using IMAP (the mysql server is not accessible on port 3306 anyway). A quick google resulted in a suggestion from Robert (who by now must be on every single list I'm on or rather vice-versa) about using winbind. I went off to the link he posted - http://wiki.dovecot.org/Authentication/Mechanisms/Winbind?highlight=%28winb… and the problem is that seems to indicate bind and dovecot are on the same server. So, this not being the samba list notwithstanding, is it possible to use a remote dovecot host as an authentication back-end on a local samba installation? Cheers Simon

[Dovecot] Problem overriding default quota limit
by RAUL JAREÑO MORAGO 28 Jul '12

28 Jul '12

Hi, We get user's quota limit from LDAP. It works fine when user has quota attribute in LDAP (this is when it's different from default quota). But when user doesn't have quota limit attribute Dovecot doesn't take default value defined in quota plugin and assign unlimit quota to user. Our configuration is similar to the example from wiki ( http://wiki2.dovecot.org/Quota/Configuration ). This is the plugin configuration _plugin {_ _ quota = maildir:User quota_ _ quota_rule = *:storage=1G_ _ .........._ _}_ And this is the recovered fields in LDAP search: _user_attrs = mailMessageStore=home,mailquotasize=quota_rule=*:bytes=%$_ It works if user has mailquotasize in its LDAP entry. But if it hasn't it Dovecot assign 0 instead of *:STORAGE=1G This is the log when LTMP deliver a mail to a user without mailquotasize attribute: _auth: Debug: master in: USER#0111#011eepp68#011service=lmtp#011lip=172.31.100.120#011lport=24#011rip=172.31.100.119#011rport=41452_ _auth: Debug: userdb-cache(eepp68,172.31.100.119): miss_ _auth: Debug: ldap(eepp68,172.31.100.119): user search: base=o=Junta de Castilla-La Mancha,c=ES scope=subtree filter=(uid=eepp68) fields=mailMessageStore,MAILQUOTASIZE_ _auth: Debug: ldap(eepp68,172.31.100.119): result: mailMessageStore=/buzones1/e/eepp68; MAILQUOTASIZE MISSING_ _auth: Debug: master out: USER#0111#011eepp68#011home=/buzones1/e/eepp68#011QUOTA_RULE=*:BYTES=_ _lmtp(8235): Debug: auth input: eepp68 home=/buzones1/e/eepp68 quota_rule=*:bytes=_ _lmtp(8235): Debug: Added userdb setting: plugin/quota_rule=*:bytes=_ _lmtp(8235, eepp68): Debug: Effective uid=11184, gid=2110, home=/buzones1/e/eepp68_ _lmtp(8235, eepp68): Debug: Quota root: name=User quota backend=maildir args=_ _lmtp(8235, eepp68): Debug: Quota rule: root=User quota mailbox=* bytes=0 messages=0_ I tried it with defining default_fields in userdb but I get the same result: _userdb {_ driver = ldap args = /etc/dovecot/dovecot-ldap-lmtp.conf.ext default_fields = quota_rule=*:bytes=1073741824 } If I don't recover mailquotasize (user_attrs = mailMessageStore=home) Dovecot assign default quota limit, so it works in this case: auth: Debug: master in: USER#0111#011eepp68#011service=lmtp#011lip=172.31.100.120#011lport=24#011rip=172.31.100.119#011rport=41427 auth: Debug: userdb-cache(eepp68,172.31.100.119): miss auth: Debug: ldap(eepp68,172.31.100.119): user search: base=o=Junta de Castilla-La Mancha,c=ES scope=subtree filter=(uid=eepp68) fields=mailMessageStore auth: Debug: ldap(eepp68,172.31.100.119): result: mailMessageStore=/buzones1/e/eepp68 auth: Debug: master out: USER#0111#011eepp68#011home=/buzones1/e/eepp68 lmtp(8198): Debug: auth input: eepp68 home=/buzones1/e/eepp68 lmtp(8198, eepp68): Debug: Effective uid=11184, gid=2110, home=/buzones1/e/eepp68 lmtp(8198, eepp68): Debug: Quota root: name=User quota backend=maildir args= lmtp(8198, eepp68): Debug: Quota rule: root=User quota mailbox=* bytes=1073741824 messages=0 Any idea about where is the problem?

The default is not taken since your LDAP query returns a quota_rule with an empty bytes= value when the mailquotasize entry is missing.

[Dovecot] emails are being marked as read auto-magically
by Joe Beaubien 28 Jul '12

28 Jul '12

Hi, I'm having a weird issue with dovecot 2.1.7 (using the latest thunderbird client). Something, I have emails that mark themselves as read on their own. No one touches them, and they get marked as read. I try to re-mark them as unread, but a few seconds later, they get marked as read again. The same problem happens in reverse (emails marks as unread become read). Has anyone ever experienced anything similar? I cannot see any warnings or errors in the dovecot logs, so I'm not sure if the problem is with thunderbird or with dovecot. However, I have never had this issue before switching from dovecot 1.0.X to dovecot 2.1.X. Unfortunately, we updated the thunderbird versions around the same time, so I feel like a dog chasing my tail on this issue. Any help would be appreciated. Regards, -Joe
