[Dovecot] virtual plugin and ACL
by Nikita Koshikov 10 Aug '09

10 Aug '09

Hello list, We are using virtual plugin for to provide users two additional folders: Company/all - it contains all messages in user's mailbox Company/favorites - here is flagged messages. Here is namespace part of config file: namespace private { prefix = Company/ separator = / location = virtual:/var/mail/virtual:INDEX=MEMORY:LAYOUT=maildir++ subscriptions = no } Everything works fine, but problem arises when someone rename or delete virtual mailbox. With above config, 1 user make changes to his mailbox, but changes distribute for entire domain. First, I have tried to add :CONTROL=/data/mail/%d/%n/data/virtual to location part of virtual namespace, but I have no luck with such settings. Directory /data/mail/%d/%n/data/virtual not even been created. Then I tried to setup ACL for virtual mailbox. Adding "acl" to mail_plugins in imap and lda section and acl=vfile to plugins config. Under /var/mail/virtual in each mailbox I create dovecot-acl file contaning: user=koshikov.n lrwstiekxa authenticated lrwstipe But this didn't work. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN AUTH=LOGIN] Server ready. a login test qwe a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH QUOTA] Logged in a list "" * * LIST (\HasNoChildren) "/" "Sent" * LIST (\HasNoChildren) "/" "Drafts" * LIST (\HasNoChildren) "/" "Spam" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\Noselect \HasChildren) "/" "Company" * LIST (\HasNoChildren) "/" "Company/all" * LIST (\HasNoChildren) "/" "Company/favorites" a OK List completed. a select Company/all * FLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk \*)] Flags permitted. * 13 EXISTS * 0 RECENT * OK [UIDVALIDITY 1249459221] UIDs valid * OK [UIDNEXT 14] Predicted next UID * OK [NOMODSEQ] No permanent modsequences a OK [READ-WRITE] Select completed. a getacl a BAD Error in IMAP command GETACL: Unknown command. a rename Company/all Company/test a OK Rename completed. After "rename completed" in /var/mail/virtual new file dovecot-acl-list is appear with content: 1249457074 test How can I get workaround for this situation ? I just need to restrict my users renaming and deleting virtualboxes.

[Dovecot] how secure is Dovecot when exposed to the Internet?
by Florin Andrei 10 Aug '09

10 Aug '09

$ dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-11-server x86_64 Ubuntu 9.04 protocols: imap imaps managesieve I need to make an IMAP (actually imaps) server available over the Internet. Unfortunately, VPN is not available (not all clients support VPN), so I will have to expose the imaps port to the Internet. My question is: how reliable is Dovecot in such a setup? I am not talking about encryption (protecting the traffic between server and client). I am talking about having the daemon exposed to anything coming in from the Internet, buffer overflows and stuff like that. What's the security history of this software in situations like this? -- Florin Andrei http://florin.myip.org/

[Dovecot] Wiki entry for expire plugin, PostgreSQL trigger needs update
by Stefan Förster 09 Aug '09

09 Aug '09

The wiki entry at http://wiki.dovecot.org/Plugins/Expire needs an update for Dovecot 1.2 and PostgreSQL: -- v1.2+: CREATE OR REPLACE FUNCTION merge_expires() RETURNS TRIGGER AS $$ BEGIN IF exists(SELECT 1 FROM expires WHERE username = NEW.username AND mailbox = NEW.mailbox) THEN UPDATE expires SET expire_stamp = NEW.expire_stamp WHERE username = NEW.username AND mailbox = NEW.mailbox; RETURN NULL; ELSE RETURN NEW; END IF; END; $$ LANGUAGE plpgsql; CREATE TRIGGER mergeexpires BEFORE INSERT ON expires FOR EACH ROW EXECUTE PROCEDURE merge_expires(); At least that's what I think after looking at the code: iter = dict_iterate_init(dict, DICT_EXPIRE_PREFIX, DICT_ITERATE_FLAG_RECURSE | DICT_ITERATE_FLAG_SORT_BY_VALUE); /* We'll get the oldest values (timestamps) first */ while (dict_iterate(iter, &key, &value) > 0) { /* key = DICT_EXPIRE_PREFIX<user>/<mailbox> */ userp = key + strlen(DICT_EXPIRE_PREFIX); [...] T_BEGIN { username = t_strdup_until(userp, p); If this code does somehow iterate usernames which are not present in the dict, I apologize.

[Dovecot] User Auth
by Richard Harwood 09 Aug '09

09 Aug '09

Hello all, I am new to the mailing list and I'm in the process of setting up a LAMP + mail server. I have configured my MTA (Postfix) to deliver messages to: /var/spool/mail/vhosts/domain.tld/name I have configured Dovecot as follows: -- # 1.2.2: /usr/local/etc/dovecot.conf protocols: imap imaps pop3 ssl: no disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_privileged_group: mail mail_location: mbox:/var/spool/mail/vhosts/%d:INBOX=/var/spool/mail/vhosts/%d/%n mail_debug: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 lda: postmaster_address: postmaster(a)example.com auth default: debug: yes passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd -- Password excepted, my passwd.dovecot file containing a single virtual user looks like: richard:{plain}password:504:505::/home/vmail The uid/gid is the same as used by Postfix (a dedicated vmail user/group). That user/group owns the mbox I am trying to manipulate in this example. When I attempt to login via telnet on port 110 I get the error: +OK Dovecot ready. user richard(a)richardaharwood.com +OK pass password -ERR Authentication failed. It seems to dislike the fact I specify the domain as part of the login username. If I repeat and login as: user richard - I am authenticated, however I get the error: -ERR [IN-USE] Couldn't open INBOX: Internal error occurred. Refer to server log for more information.

I also notice the effective uid/gid is not that specified in the passwd file? The uid/gid appears to be that of my own ssh account which is not connected to the mail account that I wish to simply access as a virtual user. Would anyone be kind enough to point me in the right direction? In a nutshell, where am I going wrong with my authentication? This is a basic setup for the time being, until I get my head around it, but any pointers would be really appreciated. Have spent quite a few hours but I don't feel much closer to getting to the bottom of it! :) Many thanks, Richard

[Dovecot] multiple auth-client sockets
by LEVAI Daniel 09 Aug '09

09 Aug '09

Hi! I'm gonna need to use dovecot's auth-client socket in an authentication program. Now the auth-client socket is only used by my MTA, which is postfix. Because postfix's smtpd process (which uses the auth-client socket) runs chrooted under postfix's spool directory, I must create the auth-client socket under that spool directory. However, to reach that socket from another chrooted program is impossible. Can I create multiple instances of auth-client sockets? I tried to define another client {} stanza in socket listen {} in dovecot.conf, but only the last client socket got created. I need only a true or false response from dovecot regarding the authentication, and I thought that this is exactly what auth-client socket will do. However, if I can not reach it, is there any alternative to this? What's up with the auth-master or auth-worker sockets? Are they capable of respond to an auth request too? btw, I'm running dovecot-1.2.3 Thanks!

[Dovecot] autocreate plugin fails to subscribe mailbox in public namespace

Hi, I'm one step away from replacing a 7 years old qmail/uw-imapd setup with some state of the art soft- and hardware. We got migration scripts and test almost done - just one thing that keeps failing: The autocreate plugin is supposed to subscribe new users to different mailboxes, one of them being in namespace "Public." - this subscription to "Public.announcements" fails. Below is a dovecot -n - and no, there are no error messages in the logs. # 1.2.2: /etc/dovecot/dovecot.conf # OS: Linux 2.6.30-bpo.1-amd64 x86_64 Debian 5.0.2 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps managesieve listen(default): *:143 listen(imap): *:143 listen(managesieve): * ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(managesieve): ssl_cert_file: /etc/ssl/owncerts/snakeoil.crt ssl_key_file: /etc/ssl/private/snakeoil.key login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login verbose_proctitle: yes mail_privileged_group: vmail mail_location: maildir:~/Maildir mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_process_size: 384 mail_plugins(default): quota imap_quota fts fts_squat acl autocreate expire trash mail_plugins(imap): quota imap_quota fts fts_squat acl autocreate expire trash mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve namespace: type: private separator: . inbox: yes list: yes subscriptions: yes namespace: type: public separator: . prefix: Public. location: maildir:/export/vmailboxes/public:INDEX=~/Maildir/public list: yes lda: postmaster_address: postmaster(a)test.cite.lan hostname: testvm06.test.cite.lan mail_plugins: quota sieve expire trash auth_socket_path: /var/run/dovecot/auth-master auth default: mechanisms: plain login cram-md5 passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: sasl master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: quota: maildir:User quota quota_warning: storage=90%% /usr/local/bin/quota-warning.sh 90 quota_warning2: storage=95%% /usr/local/bin/quota-warning.sh 95 sieve: ~/.dovecot.sieve sieve_storage: ~/sieve sieve_extensions: +imapflags fts: squat fts_squat: partial=4 full=10 acl: vfile autocreate: Trash autocreate2: Drafts autocreate3: Sent autocreate4: learn-spam autosubscribe: Trash autosubscribe2: Drafts autosubscribe3: Sent autosubscribe4: learn-spam autosubscribe5: Public.announcements autosubscribe6: INBOX expire: Trash 60 Trash/* 60 expire_dict: proxy::expire trash: /etc/dovecot/dovecot-trash.conf dict: expire: pgsql:/etc/dovecot/dovecot-dict-expire.conf Any hints are really appreciated.

[Dovecot] Creating a "default" domain
by Charles Sprickman 09 Aug '09

09 Aug '09

Hello, I'm setting up a test server to work through the issues involved in bringing a bunch of vpopmail/qmail/courier users into a postfix/dovecot server. So far I'm seeing lots of info to aid in the transition. One thing I'm lost on is that since Dovecot is providing all the auth mechanisms rather than vpopmail, I'm not sure how to emulate a particular vpopmail behavior we rely on. Vpopmail allows for the concept of a "default" domain for authentication. So if I have a bunch of domains, and one is "example.com", users in that domain can login with only the username part of their id (ie: "john") rather than supplying the domain (ie: "john(a)example.com"). I need to continue to offer this unless I want to walk a few hundred users through reconfiguring their mail clients. :) Any pointers?

[Dovecot] convert config from 1.1.2_1 to 1.1.16

Hi, Im tryin to follow a guide, telling me howto setup freebsd with postfix and dovecot. The text in bold (first section), is what the guide says, and the text that follows is what the /usr/local/etc/dovecot.conf files says. Can you please help me on how to convert from the 1.1.2_1 setup to the correct configuration for the 1.1.16? / Thank you very much. *socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } * socket listen { master { # Master socket provides access to userdb information. It's typically # used to give Dovecot's local delivery agent access to userdb so it # can find mailbox locations. path = /var/spool/postfix/private/auth mode = 0600 # Default user/group is the one who started dovecot-auth (root) #user = #group = } client { # The client socket is generally safe to export to everyone. Typical use # is to export it to your SMTP server so it can do SMTP AUTH lookups # using it. path = /var/run/dovecot/auth-client mode = 0660 }

[Dovecot] All mail in mbox disappears when using Outlook
by Frank Leonhardt 08 Aug '09

08 Aug '09

I thought I was imaging it but... I have a friend (honestly) that likes to clear his inbox every month by copying older into a folder (e.g. June-2009). Every month he complains that all the mail in the new folder has disappeared. This has happened three times now, and he's sort-of-right. I now believe it's a bug rather than him. The setup is Dovecot 1.1.3 on FreeBSD 7.0 and the client is Outlook 2003 SP3 (using IMAP). What you end up with is a folder called June-2009 with no messages visible. Outlook reckons it's completely empty - size 0. I don't know how he gets to this point, but it can't be anything that bizarre - just copying messages. It's happened three months in a row. However, he can't see the contents and I can't see the contents using Outlook. Strangely, Eudora and Squirrel have no problem. Corrupt mbox file? Probably not. If you copy the problem one, the copy works fine. The really weird thing is that if you rename the problem file (using mv) it STILL DOESN'T work. I've considered the possibility that it's got a bad lock on it, but if so, how come Squirrel and Eudora have no problem? I've searched as far as I can for any known problems using Outlook. What next?

[Dovecot] hoping someone has a suggestion
by P.A 07 Aug '09

07 Aug '09

Hi using dovecot 1.0.10 with pop/imap, using maildir, with 2000+ users mostly using pop but many using imap. Once in a great while I have problems with dovecot pop timing out. If I telnet to port 110 it just takes forever to come up or it doesn't at all, the samething happens on the imap port although 110 is always worst. At 1st when troubleshooting I was not sure what was causing the situation and when I ran out of options I stopped postfix. When I did this dovecot immediately started working again, that is port 110/143 came up fast and all the user logins were fast again. When I restarted postfix after a minute or so dovecot became slow again. While observing this situation I notice that postfix had most of the connections about 300+ in established state, while dovecot was using around 150 connections. After adjusting some of the parameters on postfix and shutting it down multiple times, suddenly everything worked but this time postfix was reporting over 3000 connections mostly in TIME_WAIT state which is normal for us. My question is what do you guys think is happening here, what is the relationship between dovecot/postfix that would cause this to happen. I'm just looking for some suggestions in case this happens again. # 1.0.10: /usr/local/etc/dovecot.conf protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: D-V1 NP09 ready. login_process_size: 384 login_processes_count: 55 login_max_processes_count: 450 mail_location: maildir:/home/%1u/%u/Maildir maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: count: 4 passdb: driver: shadow userdb: driver: passwd

[Dovecot] Bug - dovecot-auth hangs in ldap query. 1.1.16 (also in 1.2.2)
by Marek Miska 07 Aug '09

07 Aug '09

dovecot-auth hangs when many (>128) LDAP queries are submited simultaneously. (for example via pop3 benchmarking tool). Bug is in src/auth/db-ldap.c:db_ldap_request_queue_next if (queue_size > DB_LDAP_MAX_PENDING_REQUESTS) { /* wait until server has replied to some requests */ return FALSE; } (queue_size is total queue size, not only queries sent to LDAP server.) I think this condition should be: if (conn->pending_count >= DB_LDAP_MAX_PENDING_REQUESTS) {

[Dovecot] Trying to get dovecot and squirrelmail talking
by Neil Bird 07 Aug '09

07 Aug '09

I have been using dovecot+squirrelmail with no problems on my Fedora box (currently at F10). I've been using a simple mail location string along the lines of 'mbox:~/usr/mail/%u:INBOX=mbox:/var/spool/mail/%u' (sorry, that's off the top of my head, I can't get into my box from here at the moment). Essentially: standard mbox inbox in /var/spool/mail/[user], plus mbox files under ~/usr/mail. These latter are for remote access to archived Thunderbird files, which are [currently] mbox format. This works fine. However, I've had some slight issues elsewhere which I feel would be eased or solved by making my INBOX use maildir format, and keeping mails I want to remote-access more often in the top level maildir there (instead of always having to dip into the TB mboxes). To that end, I tried setting up: # want to be able to add sibling and child folders here namespace private { separator = / prefix = location = /var/spool/mail/%u inbox = yes hidden = no list = yes } # And the legacy mbox files go here under 'local' namespace private { separator = / prefix = local/ location = mbox:~/usr/mail hidden = no list = yes } (with appropriate an procmail change for maildir delivery) Now, this pretty much worked the way I wanted. However, afterwards, trying to connect from squirrelmail I had it say that there were no [IMAP] folders to subscribe to, including the INBOX. I couldn't se any errors, either in /var/log/maillog or http's logs. Have I got something wrong? Am I trying to do something that's doomed to failure? -- [neil@fnx ~]# rm -f .signature [neil@fnx ~]# ls -l .signature ls: .signature: No such file or directory [neil@fnx ~]# exit

[Dovecot] Dovecot deliver uidlist issues
by Mark Zealey 07 Aug '09

07 Aug '09

Hi all, Lets say I have a maildir which doesn't contain any dovecot files but has some emails lying around in it. If I add a message to this mailbox using deliver, dovecot creates the uidlist file with a single entry (the message that was just delivered). When I then log in to the mailbox, all the other messages are added into the uidlist file in the normal order (directory list order I believe). Then, the mailbox is in a situation where anything that was delivered into the mailbox before the user logs in is at the very top of a uidlist. Unfortunately many webmail clients seem to order the mailbox by reverse uidl, so we get the situation where people log into webmail (we use @mail) after their mailboxes have been migrated to dovecot and any messages delivered between the time of migration and the time of login are put to the very end of the list. This could presumably be fixed by ordering the mailbox according to date but certainly @mail doesn't really do this very well. I've only tested this on v1.1 (1.1.17 from atrpms), but I didn't see anything in the changelog to indicate that this deliver behaviour has changed in v1.2. Perhaps there should be a deliver option to recreate the uidlist file by doing a full scan if it doesn't exist (as a login via pop/imap would do), although I'm not sure why this shouldn't be the default? (apart from deliever potentially causing a high amount of io). My current work-around is to use postlogin to remove the uidlist file when someone logs in to the mailbox for the first time which then forces it to be created in the correct order; but this is a very messy solution.

[Dovecot] connect to IMAP
by jolan D 07 Aug '09

07 Aug '09

hi, I am trying to get a webbased IMAP mail module to work. http://nocc.sourceforge.net/ But it seems it doesn't connect to it. When i try to login it says: "login is not allowed for connection" i guess it has to do with the settings of the conf file. I have dovecot installed on Centos and installed it with yum. All (basic)settings are usually set correctly during install. After trying hard still no login. So i am hoping you guys can help me out.

[Dovecot] sieve rules processing
by Nikita Koshikov 06 Aug '09

06 Aug '09

Hello list, My question: is sieve support some kind of "continue" action, to explicit tell server processing rules below current one(if current has triged)? Situation: I have few rules, which fileinto's to different directories. All is working fine, but if I want redirect all my mail for some period of time to another mailbox, I'm adding rule like this, to be processing first. if anyof (true) { redirect "koshikov(a)gmail.com"; keep; } Mail redirecting, but keep state store messages to INBOX. All I want - to process other rules, which will move message to the right imap directory. This situation also happens with vacation sieve-action. In sieve rfc I didn't find any workaround to that actions. Maybe someone know how to make sieve working in described way?

[Dovecot] deliver is curious
by Sven Strickroth 06 Aug '09

06 Aug '09

Hi, Im' using deliver with postfix (mailbox_command = /usr/lib/dovecot/deliver -n -m "$EXTENSION"). In dovecot.conf I've set mail_location to maildir:/var/spool/imap/users/%u/Maildir It works, but not for ONE "special" email. If I send mail to e.g. th(a)trg-oha.de it gets correctly delivered (see noerror.txt), but I have one mail with an attachment (i cannot provide it because of privacy reasons) where i get the attached error. How comes that deliver doesn't use the mail_location but the real home-directory (from ldap, it doesn't exist on the mailserver) of that user in this case? -- Best regards, Sven mailto:sven@clamav.net ClamAV, a GPL anti-virus toolkit http://www.clamav.net Aug 3 00:57:40 mailsrv postfix/qmgr[15624]: 4C8582024C: from=<kt(a)gmx.de>, size=1436493, nrcpt=1 (queue active) Aug 3 00:57:40 mailsrv dovecot: deliver(th): Home dir not found: /home/daten/user/lehrer/th Aug 3 00:57:40 mailsrv dovecot: deliver(th): Namespace: type=private, prefix=, sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes Aug 3 00:57:40 mailsrv dovecot: deliver(th): maildir: data=/var/spool/imap/users/th/Maildir Aug 3 00:57:40 mailsrv dovecot: deliver(th): maildir++: root=/var/spool/imap/users/th/Maildir, index=, control=, inbox=/var/spool/imap/users/th/Maildir Aug 3 00:57:40 mailsrv dovecot: deliver(th): Namespace: type=shared, prefix=users.%n., sep=., inbox=no, hidden=no, list=(null), subscriptions=no Aug 3 00:57:40 mailsrv dovecot: deliver(th): shared: root=, index=, control=, inbox= Aug 3 00:57:40 mailsrv dovecot: deliver(th): Namespace: type=public, prefix=shared., sep=., inbox=no, hidden=no, list=(null), subscriptions=no Aug 3 00:57:40 mailsrv dovecot: deliver(th): maildir: data=/var/spool/imap/shared Aug 3 00:57:40 mailsrv dovecot: deliver(th): maildir++: root=/var/spool/imap/shared, index=, control=, inbox= Aug 3 00:57:40 mailsrv dovecot: deliver(th): Namespace : Using permissions from /var/spool/imap/users/th/Maildir: mode=0700 gid=-1 Aug 3 00:57:40 mailsrv dovecot: deliver(th): mkdir_parents_chown(/home/daten/user/lehrer/th) failed: Permission denied (euid=2684(th) egid=12(mail) missing +w perm: /home) Aug 3 00:57:40 mailsrv dovecot: deliver(th): copy: i_stream_read() failed: Permission denied Aug 3 00:57:40 mailsrv dovecot: deliver(th): msgid=<F915DEB780CD459A93FA6A3E9B4564BA@EeeTh>: save failed to INBOX: Internal error occurred.

[Dovecot] Deliver LDA versus vdelivermail
by Wouter van der Schagt 05 Aug '09

05 Aug '09

Good morning all, I have a question. Due to my interest in the Sieve plug-in. I'm considering to change the LDA on my production servers from 'vdelivermail' from vpopmail to 'deliver' from Dovecot. However I'm not sure how to go about doing this or whether there are any conversion issues that I should be aware of. Currently my /var/qmail/control/defaultdelivery is set to "./Maildir/". I am assuming I have to set that to: "|/var/qmail/bin/preline -f /usr/local/libexec/dovecot/deliver -d $EXT@$USER" Does it also mean I have to recreate all .qmail and .qmail-default files? Am I missing anything else? Does anybody have any experience in changing LDA on production servers? Sincerely, - Wouter van der Schagt

[Dovecot] sieve not working with Postfix and maildir
by Florin Andrei 03 Aug '09

03 Aug '09

I am moving away from Cyrus, I'm trying to migrate to Dovecot. I am trying to get Sieve working with Dovecot and Postfix and it just won't work. Postfix is able to delived new messages to the "new" subfolder of the inbox structure. After I run Thunderbird, the new message gets moved to "cur" and it shows up in my inbox. So far so good. But now I'm trying to add Sieve. I turned on managesieve, installed Avelsieve in Squirrelmail, and did some tests. No matter what, the message stays in the inbox, it does not move to the designated folder: Postfix throws it in "new", it gets moved to "cur" after accessing my email with Thunderbird, and that's it.

03 Aug '09

http://dovecot.org/tmp/dovecot-1.2.3.rc.tar.gz I thought about doing v1.2.3 release immediately, but I think I'll wait about 10-24h first. So until then, testing this RC is appreciated and hopefully we'll have a good release this time. :) + Allow namespace prefix to be opened as mailbox, if a mailbox already exists in the root dir. - Maildir: dovecot-uidlist was being recreated every time a mailbox was accessed, even if nothing changed. - listescape plugin was somewhat broken - Compiling fixes for non-Linux/BSDs

[Dovecot] Performance problem with STATUS after upgrade (1.0.15 -> 1.2.2)
by Stefan Förster 03 Aug '09

03 Aug '09

Hello list, after upgrading dovecot from 1.0.15 to 1.2.2 (and carefully reading through the upgrading notes in the wiki), I got sieve, quota and fts up and running, but I'm now suffering some kind of performance problem with the STATUS command. Symptoms: Reading mail on the IMAP server itself with "mutt", no TLS/SSL, connected through loopback interface. Whenever I idle a bit and then hit any key thereafter, for example to change into another mailbox, mutt will send a number of "STATUS" commands: # T 127.0.0.1:53604 -> 127.0.0.1:143 [AP] DONE..a0070 STATUS "postfix-buch" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0071 STATUS "postfix-users" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0072 STATUS "Trash" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0073 STATUS "Sent" (UIDNEXT UIDVALID ITY UNSEEN RECENT)..a0074 STATUS "mailman-users" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0075 STATUS "mailman-developers" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0076 STATUS "de-postfix-users" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0077 STATUS "amavis-users" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0078 STATUS "spam" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0079 STATUS "localreports" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0080 STATUS "Drafts" (UIDNEXT UIDVALIDITY UNSEEN R ECENT)..a0081 STATUS "exim-users" (UIDNEXT UIDVALIDITY UNSEEN RECENT).. # (The whole conversation is available as: http://www.incertum.net/~cite/dovecot-snoop.log) Those commands take almost one(!) second to complete. I've used strace to capture what happens and made the results available at http://www.incertum.net/~cite/imap.log. With 1.0.15, I never noticed this kind of delay, and reading mail feels really sluggish at the moment. Is there any way to improve performance?

[Dovecot] Best way to get login protocol (pop3/imap) in post-login script

Hi, all. I found doc here: http://wiki.dovecot.org/PostLoginScripting and use ${USER}, ${IP} to track last-login username and remote ip address, but how can i track the mail protocol it used? like pop3, pop3s, imap, imaps? Currently, i wrote shell script as post-login script, and use below command to get protocol: ---- $(basename ${MAIL_PLUGIN_DIR}) ---- But is it the best way to get it? Thanks very much. :) -- Best Regards.

[Dovecot] How to delete retrieved mail
by Don Muller 03 Aug '09

03 Aug '09

Hi All, I use Dovecot and XMail on a QNAP TS-509 NAS. QNAP has combined the two into a package they call XDove. Everything seems to be working great except for one thing. When Dovecot retrieves the mail from XMail it is not removing it from XMail. It is leaving a copy on XMail. Is there an option I can set in Dovecot so it will delete the mail message from XMail when it retrieves it. Thanks Don

Accepting any password is not the right solution. 2nd: If user does not present a client certificate, he have to authenticate by username/password. In both cases user data is read from userdb LDAP, which is already working. I was not able to get both auth schemes working at same time. With Postfix such a config is fully operable. regards Christian

[Dovecot] Public folders, individual SEEN flags
by Keith Edmunds 03 Aug '09

03 Aug '09

Hi list I'm trying to set up shared public folders with individual SEEN flags. I've set up three test users, but as soon as one of them marks a mail in the public folder as seen or unseen, that change is propagated to all three users. If I watch the dovecot.index.log file in each user's directory for the public folder, I see all three change their last access time as soon as one user changes the SEEN status of a mail. Any hints as to what I'm doing wrong gratefully received, thanks. -------------------------------------------------------------------------------- # dovecot --version 1.2.1 -------------------------------------------------------------------------------- # dovecot -n # 1.2.1: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.2 log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: public separator: / prefix: shared/ location: maildir:/home/publicfolders:INDEX=~/Maildir/public list: yes auth default: passdb: driver: pam userdb: driver: passwd -------------------------------------------------------------------------------- # ls -l /home/publicfolders/dovecot-shared -rw-rw-r-- 1 publicfolders publicfolders 0 2009-07-27 15:01 /home/publicfolders/dovecot-shared --------------------------------------------------------------------------------

[Dovecot] expire plugin no delete 1.2.1
by Robert Schetterer 03 Aug '09

03 Aug '09

Hi Timo, all of my tests fail with expire plugin, mail simply not get deleted i cant find any stuff in the logs why it does not or should not work. My guess that there is a problem with virtual plugin and/or shared namespace. It shouldnt be a problem with acl starting the script over cron as root am i right ? do you have any idea why it fails, is there a way to ignore all unneeded shared or virtual namespaces ? should there be a entry in the log when expire time is reached and deletion is unsuccessfull ? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] Shared mailboxes and INBOX
by Keith Edmunds 03 Aug '09

03 Aug '09

I'm trying to implement a shared mailbox: in other words, we have a generic email address ("security@") which we want a number of users to be able to monitor. The problem I have is that users can see folders under that shared mailbox but can't see the INBOX. All the users in question have their own INBOX in their private namespace, so does this raise a conflict with monitoring another mailbox's INBOX? Configuration: -------------------------------------------------------------------------------- # dovecot -n # 1.2.1: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.2 log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: public separator: / prefix: shared/ location: maildir:/home/publicfolders:INDEX=~/Maildir/public list: yes namespace: type: shared separator: / prefix: security/ location: maildir:/home/securitymailbox/Maildir:INDEX=~/Maildir/securitymailbox list: yes auth default: passdb: driver: pam userdb: driver: passwd -------------------------------------------------------------------------------- Thanks, Keith

[Dovecot] sieve filtering setup
by Jonathan Siegle 02 Aug '09

02 Aug '09

I'm looking at implementing sieve in my environment. Software is: dovecot-1.2-sieve revision 1022:3c9a22c28156 dovecot-1.2 revision 9269:a303bb82c1c9 AIX 5.3 with sendmail mta using prescribed deliver lda. I have a few questions. I'll have 110k sieve files(1 for each user). Does sieve read the file each time a new message is accepted by sendmail? Are there any measurements on cpu load for sieve filters? Thanks, Jonathan

[Dovecot] Managesieve configuration problem
by listacc＠gmx.de 02 Aug '09

02 Aug '09

Hello! I'm trying for a lot of time to make managesieve working with dovecot 1.1.17 and virtual users on openSuSE 11.1. I think I'm doing some misconfiguration, but I can't figure it out. Perhaps it's something with the paths to the sieve scripts? In dovecot.conf I find in the comments: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ protocol managesieve { #(...) # Specifies the location of the symlink pointing to the active script in # the sieve storage directory. This must match the SIEVE setting used by # deliver (refer to http://wiki.dovecot.org/LDA/Sieve#location for more # info). Variable substitution with % is recognized. # Take care: if a file in a maildir: begins with a '.', it is recognized # as a folder; so, avoid this. #sieve=~/.dovecot.sieve sieve = /drbd/mail/vmail/%d/%n/dovecot.sieve } ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "This must match the SIEVE setting used by deliver", so I have to take a look to LDA section, no? But there I don't find any hint for sieve settings: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ protocol lda { # Address to use when sending rejection mails. postmaster_address = postmaster(a)mydomain.tld # Hostname to use in various parts of sent mails, eg. in Message-Id. # Default is the system's real hostname. #hostname = # Support for dynamically loadable plugins. mail_plugins is a space separated # list of plugins to load. mail_plugins = cmusieve quota mail_plugin_dir = /usr/lib64/dovecot/modules/lda # If user is over quota, return with temporary failure instead of # bouncing the mail. #quota_full_tempfail = no # Format to use for logging mail deliveries. You can use variables: # %$ - Delivery status message (e.g. "saved to INBOX") # %m - Message-ID # %s - Subject # %f - From address #deliver_log_format = msgid=%m: %$ # Binary to use for sending mails. sendmail_path = /usr/lib/sendmail # Human readable error message for rejection mails. Use can use variables: # %n = CRLF, %r = reason, %s = subject, %t = recipient rejection_reason = Your message to <%t> was automatically rejected:%n%r # UNIX socket path to master authentication server to find users. # auth_socket_path = /drbd/mail/var/run/dovecot/auth-master auth_socket_path = /var/run/dovecot/auth-master } ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I tried to log in to managesieve manually with gnutls-cli, and that was successfull. I was able to authenticate. But when I try to put the example script from dovecot wiki (http://wiki.dovecot.org/ManageSieve/Troubleshooting) ~~~~~~~~~~~~~~~~~~~~~~~~~~~ PUTSCRIPT "hutsefluts" {6+} keep; ~~~~~~~~~~~~~~~~~~~~~~~~~~~ I get no ~~~~~~~~~~~~~~~~~~~~~~~~~ OK "Putscript completed." ~~~~~~~~~~~~~~~~~~~~~~~~~ there happens nothing, managesieve seems to wait for something else. When I look now into the directory where the script should be stored (the folder has been created automatically) I don't find any script file but a folder "tmp" that contains a plaintext file with the script commands inside, eg. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ hutsefluts-12345678.M033562P2271.imap.sieve ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ After disconnecting, this file disappears. In the dovecot.info log it looks like this: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ dovecot: Jul 30 14:51:56 Info: auth(default): master out: USER 16 test(a)mydomain.tld home=/drbd/mail/vmail/mydomain.tld/test mail=maildir:/drbd/mail/vmail/mydomain.tld/test uid=5001 gid=5001 quota_rule=*:storage=512000000B dovecot: Jul 30 14:51:56 Info: managesieve-login: Login: user=<test(a)mydomain.tld>, method=PLAIN, rip=192.168.200.39, lip=192.168.200.40, TLS dovecot: Jul 30 14:51:56 Info: MANAGESIEVE(test(a)mydomain.tld): Effective uid=5001, gid=5001, home=/drbd/mail/vmail/mydomain.tld/test dovecot: Jul 30 14:51:56 Info: MANAGESIEVE(test(a)mydomain.tld): sieve-storage: using active sieve script path: /drbd/mail/vmail/mydomain.tld/test/dovecot.sieve dovecot: Jul 30 14:51:56 Info: MANAGESIEVE(test(a)mydomain.tld): sieve-storage: using active sieve script path: /drbd/mail/vmail/mydomain.tld/test/dovecot.sieve dovecot: Jul 30 14:51:56 Info: MANAGESIEVE(test(a)mydomain.tld): sieve-storage: using sieve script storage directory: /drbd/mail/vmail/mydomain.tld/test/sieve dovecot: Jul 30 14:51:56 Info: MANAGESIEVE(test(a)mydomain.tld): sieve-storage: relative path to sieve storage in active link: sieve/ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ../vmail/mydomain.tld/test/dovecot.sieve is missing completely.

[Dovecot] Best way to get login protocol (pop3/imap) in post-login script
by Zhang Huangbin 02 Aug '09

02 Aug '09

Hi, all. I found doc here: http://wiki.dovecot.org/PostLoginScripting and use ${USER}, ${IP} to track last-login username and remote ip address, but how can i track the mail protocol it used? like pop3, pop3s, imap, imaps? Currently, i wrote shell script as post-login script, and use below command to get protocol: ---- $(basename ${MAIL_PLUGIN_DIR}) ---- But is it the best way to get it? Thanks very much. :) -- Best Regards.
