[Dovecot] Moving mail between folders
by Ilo Lorusso 13 Nov '08

13 Nov '08

Hi, Ive just installed Dovecot and postfix and Ive created a whole bunch of folders and started moving my mail around. Ive noticed that it copies the mail to the folder I wish to move the mail to and leave the original message waiting to be purged in the original folder Is there a way to have dovecot delete it straight after it has been moved? as I don't think users are going to take well to this change? any help would be appreciated Thanks, Ilo.

[Dovecot] dovecot pop3 performance, what size installation
by Brandon Lamb 13 Nov '08

13 Nov '08

Hello, I was wondering if anyone could tell me their results and maybe help me get an idea how big our mail system installation and usage is. For dovecot pop3 and nfs backend, I am curious how many machines I should expect to need. Here are my stats for what I can tell. 5-7 connections per second average, 8-12 connections per second peak. 30-50 constant connections between 3 servers (8-20+) on each server. We are servicing about 14,000+ email accounts. These are just the pop3 login stats, a lot of users use both or imap through our webmail. My question I guess is whether this is on the small side, medium or larger side mail setup, and should I be thinking that only 1 or 2 servers should be able to handle the load. Right now I am splitting it between 3. Should a single quad core box be able to handle this? Not sure if this is a simple question or not. Im not including my dovecot -n just because this is more of a generic question.

[Dovecot] removing uid, index and cache files
by Lars Uhlmann 13 Nov '08

13 Nov '08

Since a couple of days we're facing a problem with dovecot/MUA and multiple appeareances of single mails. The mail is physical existant only once but outlook shows it twice or more times. Then after some minutes these multiple "virtual" mails just disappear. Because this happens with different MUAs (Outlook and Thunderbid) I assume dovecot causes the problem. All mail are received by »getmail« from outside via POP3 and delivered to the users local Maildir. This was working without problems for over a year now. Is it save to remove to following files (will dovecot rebuild them) from every users Maildir? dovecot.index dovecot.index.cache dovecot.index.log dovecot.index.log.2 dovecot-uidlist Thahks in advance, Lars

[Dovecot] Sieve authentication / directory issue after upgrade to 1.0.13.
by Drew Calcott 12 Nov '08

12 Nov '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, I have come across a problem after upgrading from 1.0.rc17 to 1.0.13 (debian builds 1.0.13 is from etch-backports). I initially upgraded as 1.0.rc17 isn't compiled with regex support, so vacation messages that were uploaded via horde were being rejected. (Everything else was working fine, just messages that required regex functions were failing). Horde is uploading the filters via pysieved, which is then in turn placing them in the directory of: - --------- /shared/spool/active/%d/%0.1u/%1.1u/%n/sieve/ingo - --------- At least, it was previously. Since upgrading, dovecot has changed the way it passes authentication details to pysieved and the domain is no longer included in the username, so the domain cannot be parsed and pysieved fails as it is unable to strip a value for %d. (as a quick aside, this isn't an issue with single domain servers as there is a "defaultdomain" option that will force the value for %d, however, since we have 9 domains to deal with, this isn't going to cut it). Prior to upgrade, authentication was passed as thus (= are a new line in case the formatting dies) - -------- ======= > 'AUTH\t1\tPLAIN\tservice=pysieved\tresp=YWNhbD* restofstring * ====== < OK\t1\tuser=acal030(a)sit.auckland.ac.nz\tuser=acal030\t\n' ===== Finished SASL authentication : {'username':'acal030(a)sit.auckland.ac.nz', 'result': 'OK'} ===== Plugin returned home :'/shared/spool/active/sit.auckland.ac.nz/a/c/acal030/' = Authenticated user acal030(a)sit.auckland.ac.nz - -------- Both user and user@domain were being passed and it was a matter of simple nagging of the pysieved guys to update their code to strip the required information. However, the new version is passing auth like this: - -------- ======= > 'AUTH\t1\tPLAIN\tservice=pysieved\tresp=YWNhbD* restofstring * ======= < 'OK\t1\tuser=acal030\n' ===== Finished SASL authentication : {'username': 'acal030', 'result': 'OK'} ===== Plugin returned home : '/shared/spool/active//a/c/acal030/' - ------- The only change to the dovecot config I have made is to add "allow_all_users=yes" to userdb static as the new version was a lot stricter about the passdb pam lookup not containing the user data (and failing completely as a result). In the dovecot logs themselves, the following lines were from the earlier build: - ------ Info: auth(default): client out: OK 1 user=acal030(a)sit.auckland.ac.nz user=acal030 Info: auth(default): master in: REQUEST 243 23994 1 Info: auth(default): master out: USER 243 acal030(a)sit.auckland.ac.nz home=/blah, mail=/blah etc. - ------ Compared to this from the new one: - ------ Info: auth(default): auth(acal030(a)sit.auckland.ac.nz,130.216.39.182): username changed acal030(a)sit.auckland.ac.nz -> acal030 Info: auth(default): client out: OK 1 user=acal030 Info: auth(default): prefetch(acal030,130.216.39.182): success Info: auth(default): master out: USER 2 acal030 home=/blah, mail=/blah etc. - ------ I am rather at the end of my tether with this, unfortunately. :( I have browsed through many wiki pages looking for a possible solution or config variable I may have missed, but I really am coming up dry. Cleaned up dovecot.conf is at: http://pastebin.com/m7f4303af Should anyone want strace logs or whatever, I'm more than happy to make with them. Thanks in advance for any assistance.

[Dovecot] Dovecot master process
by Steven F Siirila 12 Nov '08

12 Nov '08

We are running into a situation where Dovecot master is simply trying to do too much. It some situations, we are finding that there are times in which it cannot service requests. Restarting Dovecot seems to help in these situations, possibly due to the fact that it no longer has to manage its THOUSANDS of file descriptors for pipes to the many imap/proxy processes that it uses for logging. Is there a way to turn off logging through the master process (in exchange for lesser security)? If not, would it be easy to have the master process do its logging using separate threads (which would help on some modern hardware)? Finally, would it be easy to delegate the task of logging to a dedicated process? We are still running Dovecot 1.0.0 at this time, on Solaris 10 servers. -- Steven F.

I have mailreaver running perfectly otherwise, but it doesn't seem to be called correctly from dovecot-antispam - the css files show no change. Piping a message to the command... `/usr/share/crm114/mailreaver.crm --good -u /shared/domains/domain.tld/users/pfern/.crm/` works as expected, and the logs don't indicate anything useful that I can see as to why it isn't working from dovecot.

[Dovecot] How to specify /var/spool/mail/m/i/mike
by Network Operations 11 Nov '08

I was wondering if somebody could tell me how I can tell dovecot (IMAP) to read users' mail boxes at /var/spool/mail/{1st char}/{2nd char}/username . For example: Mailbox for user 'mike' would be located at /var/spool/mail/m/i/mike 'karen' would be at /var/spool/mail/k/a/karen etc... Is this possible is version 1.1.6? Please advise. Thanks JB

Thanks for > testing! It solves the problem here as well =) Thanks for the update. Do you plan to implement 'out of band' dspam calling? BTW maybe there is no need for a separate 'queue' folder especially as we only need a message signature. I think it can be stored in some buffer array so as the dspam calls are made i.e. during idle time (or during final cleanup at the latest). Also I am attaching a couple of patches that might be useful. dspam-exec.c.patch adds debug-dumping of the dspam reply (it turned out quite useful not only for the stack corruption problem). Makefile.patch fixes the syntax to compile with gmake under FreeBSD 6.1 and also adjusts the installed plugin permissions. Best wishes Eugene

[Dovecot] NFS Unbreakable lock issues
by Rod Treweek 11 Nov '08

11 Nov '08

Hello All, We are struggling to find a solution to a problem we are encountering with a load-balanced email setup. Currently, we have a Coyote loadbalancer, and 3 Postfix/Dovecot nodes that then get their information from a mysql database. The problem is that after a couple weeks, we start seeing NFS locking issues occur, which then takes email completely down, requiring a site visit to basically do an interactive mode reboot to shut off NFS so that we can remount the filesystem again. We have our mailstore on an Aberdeen NAS which is accessed over NFS v. 4. Dovecot version 1.1.2 Here's the relevant mysql string: grep -v '^ *$#.*$\?$' dovecot-mysql.conf driver = mysql connect = host=X.X.X.X dbname=Something user=Something password=Something password_query = SELECT username as user, password, concat('/NFS1MAILDIR/mailSysV2/', maildir) as userdb_home, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as userdb_mail, 143 as userdb_uid, 143 as userdb_gid, concat('*:bytes=', floor(quota*1024)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' user_query = SELECT concat('/NFS1MAILDIR/mailSysV2/', maildir) as home, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as mail, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as maildir, 143 AS uid, 143 AS gid, concat('*:bytes=', floor(quota*1024)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' And here's what our configuration is on each of the nodes: dovecot -n # 1.1.2: /usr/local/etc/dovecot.conf protocols: imap pop3 ssl_ca_file: /usr/local/etc/dovecot/certs/tdpserver.crt ssl_cert_file: /usr/local/etc/dovecot/certs/tdpserver.crt ssl_key_file: /usr/local/etc/dovecot/certs/tdpserver.key ssl_parameters_regenerate: 0 ssl_cipher_list: ALL:!LOW:!SSLv2 disable_plaintext_auth: no login_dir: /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_user: postfix login_greeting: Something witty here.. login_process_per_connection: no login_max_connections: 512 max_mail_processes: 2048 mail_max_userip_connections: 50 verbose_proctitle: yes first_valid_uid: 69 last_valid_uid: 500 first_valid_gid: 69 last_valid_gid: 500 mail_access_groups: postfix mail_privileged_group: postfix mail_location: mbox:/NFS1MAILDIR/mailSysV2/%d/%u:INDEX=/usr/local/mail/indexes/%d/%1n/%n mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: 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_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota 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 imap_client_workarounds(default): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: login plain user: dovecot passdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf userdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: dovecot group: dovecot plugin: quota: dict:user::proxy::quota imap_quota: dict:user::proxy::quota quota_rule: *:storage=528576 dict: quota: mysql:/usr/local/etc/dovecot/dovecot-dict-quota.conf Any help you can offer is greatly appreciated, as well as opinions on any other 'validated' postfix/dovecot email enterprise design solutions.

[Dovecot] First release (v0.1.0) of the new Sieve implementation for Dovecot v1.2
by Stephan Bosch 11 Nov '08

11 Nov '08

Hello Dovecot users, Finally, after little more than a year, I finished the first release of the new Sieve implementation for Dovecot. The main reason for rewriting the Sieve engine is to provide more reliable script execution and to provide better error messages to users and system administrators. Also, since the Sieve language evolves quickly, with new language extensions published every year, the aim is to provide support for quickly extending the engine with new features. This implementation aims to comply to RFC8225 and it provides support for the following Sieve language extensions: * fileinto * reject * envelope * encoded-character * vacation * subaddress * relational * regex * imap4flags * copy * include * body * variables In comparison to the old CMU Sieve plugin, I added support for the very useful variables extension. However, the notify extension is notably missing. This will be implemented for next major release (0.2.x). Refer to the README file for a full list of its features: http://hg.rename-it.nl/dovecot-libsieve/raw-file/0.1.0/README Installation ------------ The source package is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.0.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.0.tar.gz.sig Alternatively, it can be cloned from the mercurial repository: hg clone http://hg.rename-it.nl/dovecot-libsieve The compilation procedure is identical to the cmusieve plugin (http://wiki.dovecot.org/LDA/Sieve) Don't forget to execute ./autogen.sh first if you obtained the sources through mercurial. This release will not compile against Dovecot versions older than v1.2.alpha3. The configuration is very similar to the original plugin as well. The most notable difference is the name of the plugin, which is simply 'sieve' in stead of 'cmusieve'. After compilation, the Sieve engine can be verified before deployment using the included test suite. This is done by executing `make test` in the top of the source tree. The test suite is known to finish flawlessly on the i386 and amd64 platforms. The test suite is not very comprehensive yet, as it only tests the evaluation of scripts and omits testing the actual execution of actions. As this release contains about 30k effective lines of fresh code, bugs will eventually surface. Make sure that you provide enough information to reproduce the problem if you report bugs, i.e. the script and the mail message that caused the problem and/or relevant log entries. Have fun testing the new Sieve plugin. Don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

Hi Timo, in the wiki there is only talked about gfs filesystem are there any known breaking problems using ocfs2 with dovecot ? in my vmware setup ocfs2 seems to be more debian/ubuntu config friendly like gfs dont got gfs to run, perhaps this might be better on suse/centos/redhat but i simply want to use ubuntu hardy server version -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] antispam plugin claims "antispam signature not found"
by Jakob Curdes 09 Nov '08

09 Nov '08

Hi, I am trying to setup the antispam plugin using the direct dspam backend. I have set antispam_signature = X-DSPAM-Signature in dovecot.conf and in all mails I have signature lines like X-DSPAM-Signature: 1,49084a24139132188715614 but still, if I try to move a mail into the spam folder, i get the IMAP error message "antispam signature not found". I thought it might have to do with permissions and made sure that the user running dovecot is able to execute the dspam binary. I also tried to enable debug logging to syslog (via the .config file in the make process) but I do not see any debug messages showing up; where should these go? to the mail facility? Perhaps somebody who has a working setup can shed some light on this? Yours, JC

[Dovecot] Renames across namespaces
by Ben Winslow 08 Nov '08

08 Nov '08

Will Dovecot ever support renames across namespaces? I'm attempting to support mailboxes under "INBOX" for compatibility with Courier, which I'm trying to replace, while also supporting mailboxes with no prefix. I don't want to confuse new users (who aren't already subscribed to their mailboxes with the INBOX prefix) by listing the entire tree twice (parented at the root and at INBOX.) This configuration seems to provide what I want: mail_location: maildir:~/mail namespace: type: private separator: . prefix: INBOX. inbox: yes hidden: yes namespace: type: private separator: . list: yes subscriptions: yes ...except that, when a legacy user tries to delete a mailbox under INBOX, Thunderbird (at least) renames the mailbox to make it a child of Trash at the root, e.g.: tag123 RENAME "INBOX.test" "Trash.test" tag123 NO Can't rename mailbox to another storage type. I was a little surprised that it didn't work at first, since they're both using the same (default) mail_location, but I see why it doesn't work after looking at the code. Is there any chance cross-namespace (and even cross-storage _type_) wouldn't eventually be supported? (I guess that the big problem is making cross-type renames appear atomic to clients.) Is there a better way to do what I'm trying to do? -- Ben Winslow <rain(a)bluecherry.net>

[Dovecot] Fetch order

Hi all, Is there a function to modify the fetch order of messages? We have just migrated from Courier to Dovecot and I notice that there is a slight difference in the way messages are fetched in Dovecot compared to Courier. Both Courier and Dovecot sort the mailbox correctly (UID SORT (REVERSE ARRIVAL) UTF-8 ALL), for example: [ 13:22:02.790 ]50800314 UID SORT (REVERSE ARRIVAL) UTF-8 ALL * SORT 195 194 193 192 191 190 189 188 187 186 185 184 183 182 181 180 179 178 177 176 175 174 173 172 171 170 169 168 167 166 165 164 163 162 161 160 159 158 157 156 155 154 153 152 151 150 149 148 147 146 145 144 143 142 141 140 139 138 137 136 135 134 133 132 131 130 129 128 127 126 125 124 123 122 121 120 119 118 117 116 115 114 113 112 111 110 109 108 107 106 105 104 103 102 101 100 99 98 97 96 95 94 93 92 91 90 89 88 87 86 85 84 83 82 81 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 43 44 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 1 4 8 10 15 18 20 25 14 19 2 3 5 9 13 17 21 22 7 11 16 6 12 23 24 50800314 OK Sort completed. But if we fetch the latest 25 messages, Dovecot will fetch the lowest UID in the list first, so from the example above it would fetch UID 171,172,173 and so on. Courier on the other hand would start the fetch on UID 195,194,193 and so on. We have an internal developed webmail application that has been affected by this change, so I am just wondering whether there is a interim fix while we fix our webmail application to cater for this. Thanks, Warren

[Dovecot] index storage usage
by Giorgenes Gelatti 07 Nov '08

07 Nov '08

Hello there, I failed in finding the answer in the wiki so i'm asking it here. In average, how much the dovecot's indexes increase the usage of storage, compared to a standard maildir mailbox? I believe it would be a function of the number of messages instead of the message's size. Is there a known aproximated function for that? Thank you. gpg

[Dovecot] (1.0.13) fsync failed: Disk quota exceeded for some accounts
by Eric Marin 07 Nov '08

07 Nov '08

Hello all, We've recently migrated the mail server used by our 5000 students, from Tru64/UW-IMAP/Procmail/Postfix/mbox to Debian Etch/Dovecot/Deliver/Postfix/Maildir E-mails are not stored directly on the server (except for index and control files), but on an NAS that exports the students' homedirs on NFS. Each student has a 100MB quota on the NAS. Here is the configuration : vega:~# dovecot -n # 1.0.13: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 listen: [::] ssl_disable: yes disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no login_process_size: 32 login_max_processes_count: 1024 mail_privileged_group: mail mail_location: maildir:~/Maildir:INDEX=/var/mail/index/%u:CONTROL=/var/mail/control/%u maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv namespace: type: private separator: / inbox: yes namespace: type: private separator: / prefix: mail/ hidden: yes auth default: cache_size: 1024 passdb: driver: pam args: blocking=yes cache_key=%u dovecot userdb: driver: passwd args: blocking=yes When one mails a student that has filled his quota, one immediately receives this message : "Your message to <studentx> was automatically rejected: Not enough disk space Reporting-UA: vega; Dovecot Mail Delivery Agent Final-Recipient: rfc822; studentx Original-Message-ID: <490F0A9A.8030109(a)utc.fr> Disposition: automatic-action/MDN-sent-automatically; deleted" And in /var/log/mail.log : (...) save failed to INBOX: Not enough disk space (...)

After about a week : vega:~# qshape deferred T 5 10 20 40 80 160 320 640 1280 1280+ TOTAL 500 1 4 3 9 12 6 8 17 140 300 etu.utc.fr 499 1 4 3 9 12 6 8 17 139 300 vega.utc.fr 1 0 0 0 0 0 0 0 0 1 0 For the students that have this problem (about 30 for now), this happens *even* if I delete ~studentx/Maildir, /var/mail/index/studentx and /var/mail/control/studentx, let Deliver recreate the necessary files (by sending the user a mail) so that everything is clean, artificially fill the quota with a big file in the homedir, then send a mail again. It gets deferred... I have looked at the changelog for Dovecot, but have not found a clear clue that is a bug (if it is !) that has already been corrected in a more recent version... Though if possible, I'd like to keep the Debian package (from etch-backports) instead of compiling it from source. Also, while I've found Dovecot's wiki to be surprisingly informative, there are still a few points that did not seem very clear : - should I use the quota:fs plugin in this case (it seems to work out well without it for most users) ? - would it work in v1.0.13 on NFS ? - if it worked, and I enabled it, what would change for me ? - what is *supposed* to happen without the quota plugin when a user has filled his quota : mail is rejected, or mail is deferred ? - and what about imap_quota ? Best regards, Eric

[Dovecot] Compiling dovecot 1.1.6 with ICC
by Steve 06 Nov '08

06 Nov '08

Hello list I have compiled PostgreSQL with ICC (Intel C/C++ compiler) and this forces me to compile dovecot 1.1.6 as well with ICC. Trying to compile it with GCC fails, telling me it can not build with PostgreSQL support since it can not find libpq (but libpq is there!). The funny part is that I can compile dovecot 1.1.6 with GCC 4.3.2 against MySQL which is build with ICC. But I can not build against PostgreSQL build with ICC. Why is that? Does any one know the reason why PostgreSQL is treated differently then MySQL in dovecot? Well... so no way to get around to build dovecote with ICC. I can build dovecot with ICC but as soon as I start it, I get a crash. Loading the core dump into GDB does not give me much info. Probably because I have not compiled dovecot with debug symbols. Currently I am doing that. Hopefully this will produce better core dumps. I will post more info as soon as I get them. But in the mean time maybe some one has a hint for me how to get dovecot 1.1.6 to build properly with ICC? // Steve -- GMX Download-Spiele: Preizsturz!

[Dovecot] Strange and sudden deletion of mails messages
by נור דאוד 06 Nov '08

06 Nov '08

Hello everyone, I'm having a bizarre problem (bug?) concerning deletion of messages from one of the mailboxes. The platform is set up as follows: FreeBSD 7-STABLE Postfix 2.6-20080411 Dovecot 1.0.13 Webmail using RoundCube 0.1-STABLE The trace (in Postfox logs) revealed that the message has been actually received, and saved to maildir, and then viewed once in Webmail. Hitting Reply in Webmail produced an error, and the letter (somehow) was nowhere to be found on the server! I have no clue what's the cause of this. Is there a way in Dovecot to catch all commands sent to the server, thus revealing who in effect deleted the message? Thanks in advance. Noor

[Dovecot] feature request for dovecot 1.2 Master users/passwords for virtual domain admins
by Robert Schetterer 06 Nov '08

06 Nov '08

Hi Timo, currently superadmins can be configured in dovecot i.e in mysql as "superadmins" this means the can log in in any mailbox on the server this is a very nice feature in real world scenarios specially for support people in postfixadmin i.e there are also defined domainadmins ( this is for delegate usermail creation/delete etc in the postfixadmingui ) in mysql it would be nice to have or simply use postfixadmins mysql domainadmins in mysql table entries to login for domainadmins only login to mailboxes of their related maildomain this would be also massiv helpfull for postmasters/support people in a full virtual setup perhaps you might get this in dovecot 1.2 before closing at beta stage -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] How do I use plus-addressing in Dovecot 1.1.x?
by Jon Fullmer 06 Nov '08

06 Nov '08

I'm using Postfix, Amavisd-new/SpamAssassin, and Dovecot. They all run on the same server (running Linux). The mailboxes are stored on the same server in maildir format. The logical path for incoming messages (as I understand it) is: 1) received by Postfix; handed off to Amavisd-new 2) Amavisd-new checks to see whether or not it's spam/undesirable; hands off to Dovecot deliver 3) Dovecot deliver delivers the message to the local mailbox Under each of my user's mailbox is a submailbox called "spam". Just so I don't confuse terminologies (I'm no IMAP/maildir expert), for example, we have someone(a)domain.com. My configured mail_location is "maildir:/srv/mail/%d/%n", so this person's mailbox is located here: / srv/mail/domain.com/someone/ Within this directory is another mailbox: /srv/mail/domain.com/someone/.spam/ The plan is to have Dovecot deliver send a message (which has been labeled by Amavisd-new as spam) directly to the ".spam" submailbox, instead of the INBOX (/srv/mail/domain.com/someone/). With Dovecot 1.0.x, I used "plus addressing". Amavisd-new was configured so that, if a message was found to be spam, it delivered the message to Dovecot deliver, but changed the delivery address. Now, instead of "someone(a)domain.com ", it was "someone+spam(a)domain.com". Dovecot deliver took this message and delivered it correctly to the ".spam" submailbox (/srv/mail/ domain.com/someone/.spam/) Just to emphasize, this process does work (using Dovecot 1.0.x). With Dovecot 1.1.0, this process is broken. Now, spam messages are delivered to the INBOX instead, and, when checking the dovecot- deliver.log, I'm seeing "save failed to spam: Unknown namespace". As best as I can tell, the answer seems to lie in "namespaces" as a feature added in Dovecot 1.1.0. The problem is that I don't understand how I could use them to resolve this situation. I've read the documentation. I've looked at as many example configurations as I could find. Please help. I want to get this working again. I'm sure it's something very straight-forward, but I don't understand. How must I change my Dovecot 1.1.x configuration so that my "plus addressing" set up (detailed above) will work again? Or is there a better way? Thanks so much for your help, and thanks for a great product! - Jon

[Dovecot] mUTF-7 vs UTF-8 in mailbox names
by Timo Sirainen 05 Nov '08

(This is about v1.2 only, v1.1 will stay as it is.) Until today Dovecot didn't care about mailbox names. IMAP RFC requires them to be modified-UTF-7, but Dovecot didn't try to enforce it in any way. Mailbox names in Sieve scripts should be UTF-8, but currently Dovecot doesn't translate them to mUTF-7 as it should. Cyrus also did this until the latest release (v2.3.13). Now that I finally today wrote code to do mUTF-7 <-> UTF-8 conversion, Dovecot can finally do the right thing. But should there be an option to keep things backwards compatible? - IMAP: CREATE command requiring the mailbox name to be valid mUTF-7 is probably ok. Several other servers already verify that mailbox names are valid, so I doubt there are clients left anymore that don't send mUTF-7 names. - deliver -m assumes now that the mailbox name is UTF-8 and converts it to UTF-7. Should there be a -7 parameter that changes this behavior back? - Stephan's Dovecot Sieve also needs to be changed so that the mailbox name in fileinto commands can be UTF-8. If -7 parameter is added, it could control this behavior too. Also I'm wondering if in the future the mailbox names in filesystem should be converted to UTF-8. Probably not anytime soon though.. I also added imap_utf7 binary for doing mUTF-7 <-> UTF-8 conversion.

[Dovecot] Another dovecot-antispam plugin can't call dspam
by Rob Klingsten 05 Nov '08

05 Nov '08

Hi folks - I am configuring a new system and the antispam plugin is the last piece I need, everything else is working. Thanks to Johannes for this plugin, it's exactly what I want and an elegant solution for filter training. But I've been trying everything I can think of for the last 3 days to get this to work, no success. I've got: Postfix 2.5.3, dspam 3.8.0, Dovecot 1.1.6, Maildrop 2.0.4 and dovecot-antispam 1.0 tarball. I've built dspam from source with --disable-trusted-user-security to try and isolate the source of the plugin problem, which is the message at the IMAP client "Failed to call dspam." Here's what I've got configured for the plugin: antispam_signature = X-DSPAM-Signature antispam_trash = trash;Trash;Deleted Items;Deleted Messages antispam_spam = SPAM;Spam antispam_dspam_binary = /usr/local/bin/dspam antispam_dspam_args = --user %u And here's what happens: Nov 5 09:31:29 venus imap: antispam: plugin initialising (1.0-notgit) Nov 5 09:31:29 venus imap: antispam: "trash" is trash folder Nov 5 09:31:29 venus imap: antispam: "Trash" is trash folder Nov 5 09:31:29 venus imap: antispam: "Deleted Items" is trash folder Nov 5 09:31:29 venus imap: antispam: "Deleted Messages" is trash folder Nov 5 09:31:29 venus imap: antispam: "SPAM" is spam folder Nov 5 09:31:29 venus imap: antispam: "Spam" is spam folder Nov 5 09:31:29 venus imap: antispam: no unsure folders Nov 5 09:31:29 venus imap: antispam: dspam binary set to /usr/local/bin/dspam Nov 5 09:31:29 venus imap: antispam: dspam extra arg --user dump-capability Nov 5 09:31:29 venus imap: antispam: signature header line is "X-DSPAM-Signature" Nov 5 09:31:29 venus dovecot: Dovecot v1.1.6 starting up Nov 5 09:31:29 venus dovecot: auth-worker(default): mysql: Connected to 127.0.0.1 (postfix) Nov 5 09:31:30 venus dovecot: auth(default): new auth connection: pid=686 Nov 5 09:31:30 venus dovecot: auth(default): new auth connection: pid=687 Nov 5 09:31:30 venus dovecot: auth(default): new auth connection: pid=688 Nov 5 09:32:45 venus dovecot: auth(default): client in: AUTH 1 PLAIN service=imap lip=xxxx rip=xxxx lport=143 rport=55904 Nov 5 09:32:45 venus dovecot: auth(default): client out: CONT 1 Nov 5 09:32:45 venus dovecot: auth(default): client in: CONT<hidden> Nov 5 09:32:45 venus dovecot: auth-worker(default): sql(rob(a)xxxx.org,xxxx): query: SELECT password, email AS user FROM users WHERE email = 'rob(a)xxxx.org'; Nov 5 09:32:45 venus dovecot: auth(default): client out: OK 1 user=rob(a)xxxx.org Nov 5 09:32:45 venus dovecot: auth(default): master in: REQUEST 1 688 1 Nov 5 09:32:45 venus dovecot: auth(default): master out: USER 1 rob(a)xxxx.org uid=5000 gid=5000 home=/var/mail/xxxx.org/rob Nov 5 09:32:45 venus dovecot: imap-login: Login: user=<rob(a)xxxx.org>, method=PLAIN, rip=xxxx, lip=xxxx Nov 5 09:32:45 venus dovecot: auth(default): new auth connection: pid=688 Nov 5 09:32:45 venus dovecot: IMAP(rob(a)xxxx.org): Loading modules from directory: /usr/lib/dovecot/imap Nov 5 09:32:45 venus dovecot: IMAP(rob(a)xxxx.org): Module loaded: /usr/lib/dovecot/imap/lib90_antispam_plugin.so Nov 5 09:32:45 venus dovecot: IMAP(rob(a)xxxx.org): Effective uid=5000, gid=5000, home=/var/mail/xxxx.org/rob Nov 5 09:32:45 venus imap: antispam: plugin initialising (1.0-notgit) Nov 5 09:32:45 venus imap: antispam: "trash" is trash folder Nov 5 09:32:45 venus imap: antispam: "Trash" is trash folder Nov 5 09:32:45 venus imap: antispam: "Deleted Items" is trash folder Nov 5 09:32:45 venus imap: antispam: "Deleted Messages" is trash folder Nov 5 09:32:45 venus imap: antispam: "SPAM" is spam folder Nov 5 09:32:45 venus imap: antispam: "Spam" is spam folder Nov 5 09:32:45 venus imap: antispam: no unsure folders Nov 5 09:32:45 venus imap: antispam: dspam binary set to /usr/local/bin/dspam Nov 5 09:32:45 venus imap: antispam: dspam extra arg --user rob(a)xxxx.org Nov 5 09:32:45 venus dovecot: IMAP(rob(a)xxxx.org): maildir: data=/var/mail/xxxx.org/rob Nov 5 09:32:45 venus dovecot: IMAP(rob(a)xxxx.org): maildir++: root=/var/mail/xxxx.org/rob, index=, control=, inbox=/var/mail/xxxx.org/rob Nov 5 09:32:45 venus imap: antispam: signature header line is "X-DSPAM-Signature" Nov 5 09:32:45 venus imap: antispam: mailbox_is_unsure(Spam): 0 Nov 5 09:32:45 venus imap: antispam: mailbox_is_trash(INBOX): 0 Nov 5 09:32:45 venus imap: antispam: mailbox_is_trash(Spam): 0 Nov 5 09:32:45 venus imap: antispam: mail copy: from trash: 0, to trash: 0 Nov 5 09:32:45 venus imap: antispam: mailbox_is_spam(INBOX): 0 Nov 5 09:32:45 venus imap: antispam: mailbox_is_spam(Spam): 1 Nov 5 09:32:45 venus imap: antispam: mailbox_is_unsure(INBOX): 0 Nov 5 09:32:45 venus imap: antispam: mail copy: src spam: 0, dst spam: 1, src unsure: 0 Can anyone give me some more suggestions? thanks!

Hello there, I have a "subscriptions" file that is *not* ended with a line break (created by another system). When I do a "lsub "" "*"" the last mailbox name is not listed. Debugging a little showed that it looks like i_stream_next_line() is not returning the last line if it doesn't end with a line break. Is this a bug? btw, i'm using version 1.1.6. []'s

[Dovecot] MasterUser and old rev of Dovecot (0.99.14)
by Christopher Alexander 04 Nov '08

04 Nov '08

I need to migrate an old mail server running Dovecot (0.99.14) to a new server running Dovecot (1.0.7; as shipped with CentOS 5.2). My plan was to use the imapsync utility as this will "seamlessly" do the conversion from mbox to maildir between the boxes as well. I've got the MasterUser authentication working fine on the new host and was just about to start getting MasterUsers working on the old host. I noticed that the old .99 version dovecot.conf seems to have a mildly different syntax from 1.0 dovecot.conf. In particular a lot of the directives do not use braces and such. Is the .99 dovecot.conf file essentially able to deal with the same sort of syntax as outlined in the MasterUsers wiki page? [ http://wiki.dovecot.org/Authentication/MasterUsers ] I just wanted to bounce this off you guys before I started messing with a live system. ;) Thanks in advance. -- Christopher Alexander UNIX Network Administrator Broadband Network Technologies Branch (VPNT), Research Network Systems (MRNS) Communications Research Centre [ http://www.crc.ca ] Government of Canada [ http://www.gc.ca ]

It's not clear from your response that you understand why it's failing. It would seem clear that postfix doesn't see this as a local domain. Instead, it thinks you're trying to relay to somewhere else. Check your virtual_mailbox_domains file (or database) and make sure it has an entry for the new domain.

[Dovecot] v1.2.alpha1 released
by Timo Sirainen 02 Nov '08

02 Nov '08

http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha1.tar.gz http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha1.tar.gz.sig This is the only v1.2.alpha announcement I'm going to send to dovecot-news list. Next announcement will be for either v1.2.beta1 or v1.2.rc1. I'm hoping that v1.2 stabilizes pretty soon. There are no huge changes like there were in 0.99->1.0 or 1.0->1.1, so most of the bugs are probably related to new features. I'm already running v1.2 myself and it's gone through heavy stress testing with my imaptest tool, so I'm expecting it to be stable enough for real world testing with not-all-that-important servers. It's safe to jump between v1.1 and v1.2 at any time or even have them concurrently accessing the same mailboxes. Dovecot v1.2 has a lot of new IMAP extensions implemented. The biggest change comes from CONDSTORE extension which adds a new concept of "modification sequences" (modseq for short). Each message has a modseq that increases whenever a flag is changed or when the message is expunged. The client can keep track of the highest seen modseq and request only changes done since the modseq. See QRESYNC (RFC 5162) for more information. Dovecot starts keeping track of the modseqs only when the first "CONDSTORE/QRESYNC enabling command" is executed. Before that no disk space is used for modseqs. When modseqs are enabled dovecot.index file uses 8 bytes per message more space. Other implemented IMAP extensions are: ESEARCH, SEARCHRES, WITHIN, ID and CONTEXT=SEARCH. Added thread indexes to optimize IMAP THREAD command. Only the first half of threading is currently optimized, the rest will hopefully follow later. Added a non-standard X-REFERENCES2 threading algorithm where threads are sorted by their latest message instead of the thread root message. There is also no base subject merging. This may be renamed and become part of SEARCH=INTHREAD extension some day. SEARCH=INTHREAD is still a draft, but the INTHREAD search key is already implemented by Dovecot v1.2. This is mostly useful with virtual mailboxes. Virtual mailboxes: http://wiki.dovecot.org/Plugins/Virtual Then there are also some internal API changes which will make some things easier. For example lib-storage now allows handling multiple different users at the same time.

[Dovecot] pam_dovecotpw anybody?
by Steinar Bang 02 Nov '08

02 Nov '08

Samba has pam_smbpass which is a PAM module that hooks into password changing, and changes the users' samba password (presumably used for NTLM auth?), when the users change their ordinary unix/linux password. http://gitweb.samba.org/?p=samba.git;a=tree;f=source3/pam_smbpass;h=c230a1b… It shouldn't bee too hard to take the code from here, combine it with dovecotpw and create a PAM module that changes the dovecot password in a way that can be used for cram-md5. Ideally it should read the /etc/dovecot/dovecot.conf (whereever it is), and find the path of the passwd-file and use that. Has anyone else looked into doing something like this?

[Dovecot] feature request for managesieve build from packager
by seriv＠parkheights.dyndns.org 02 Nov '08

02 Nov '08

Hi everybody, dovecot-1.2 alpha3 with cmusieve, libsieve and managesieve are available as rpm packages for Sisyphus repository (http://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus, and specs/patches are available at http://git.altlinux.org/people/seriv/packages/?p=dovecot.git and http://git.altlinux.org/people/seriv/packages/?p=dovecot-sieve.git) Thank you very much Timo and Stephan! I have a feature-request for managesieve configure and Makefiles: they depend on dovecot sources as they are used for build process. I think it would be very nice to have not just --with-dovecot parameter in configure parameters, but also --with-dovecot-includes and --with-dovecot-libs. The same about cmusieve plugin: dovecot has --enable-header-install parameter, but installed headers are not sufficient for building cmusieve, I need install libraries and then modify cmusieve's Makefiles by running something like: --- for f in `find . -name Makefile` do mv -f $f $f.orig sed -e's/\$(dovecotdir)\/src$\/lib\/.*\.a$/\$(libdir)\/dovecot\/modules\1/g' \ < $f.orig > $f done --- before make in %build section. -- With best regards, Sergey Ivanov.

[Dovecot] imap processes eating IO
by Ryan Rawdon 02 Nov '08

02 Nov '08

[Ignore the previous e-mail, I somehow sent it when I was trying to paste from clipboard] I recently migrated my dovecot/postfix setup to a new machine. After doing so, I have encountered a problem where imap processes get stuck in a loop eating loads of IO on the machine. Looking at the trace (snippet below), it looks like they are sitting and reading the inbox and other folders of certain users repeatedly. This seems to be triggered by the delivery of a new e-mail to the user's mailbox while they have an IMAP client connected, though I cannot say for sure. This had never happened before on the old machine. I'm certain more information would be useful, please let me know what I can provide to help!

[Dovecot] antispam plugin problem
by Eugene 01 Nov '08

01 Nov '08

Hi people! (Especially Johannes, probably =) I recently switched to DSPAM + antispam plugin combination. Mostly I am happy but there is a problem with calling dspam-exec in order to relearn the messages. Moving messages to spam folder does not work, giving the error message 'Failed to call dspam' to client. I tried to add some debug output and here are the results: This is the output of debug("calling dspam: %s %s %s %s %s %s %s", argv[0], argv[1], argv[2], argv[3], argv[4], argv[5], argv[6]); (debugv(argv) does not produce any output for some reason) Oct 26 02:37:12 qqqqq imap: antispam: calling dspam: /usr/contrib/bin/dspam --source=error --class=spam --signature=490387db858421194018847 --user genie (null) This is the captured output of forked process Oct 26 02:37:12 qsar imap: antispam: dspam returned: ^APdata stack: Out of memory when allocating 1073741840 bytes If I understand correctly, this message is produced by dovecot before it should have launched dspam executable. I don't know why it needs 1GB of stack space for that. Changing dspam to dspamc does not help. Interestingly enough, launching 'sendmail' in mailtrain mode works ok. Do you have any ideas about what is wrong? Best wishes Eugene

[Dovecot] dovecot expire doesn't work (?)
by LÉVAI Dániel 31 Oct '08

31 Oct '08

Hi! I'm using dovecot-1.1.5 and trying to make the expire plugin work. What I've configured in dovecot.conf is the following: protocol imap,pop3,lda { mail_plugins = [...] expire } dict { expire = db:/var/dovecot/expire/expire.db } plugin { expire = spamassassin/SPAM 2 spamassassin/HAM 2 expire_dict = proxy::expire } I have a sieve rule, to copy certain messages to my "spamassassin/SPAM" folder. Then I want to expire those messages after 2 days (I think I've configured that under the plugin{} section in dovecot.conf). So the actual message saving is done by the dovecot's deliver, but I have the plugin loaded under the "protocol lda {}" section too. So I thought now I just have to wait 2 days, and run the expire-tool, and then it will expire the messages. Now I have three messages dated back to 10.25, but running the expire-tool outputs nothing. # dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Nothing in the logfiles, and nothing on the console. I have the /var/dovecot/expire directory: # ls -la /var/dovecot/expire/ total 1640 drwx------ 2 root wheel 512 Oct 26 19:47:53 2008 ./ drwxr-x--- 3 root wheel 512 Oct 27 07:57:42 2008 ../ -rw------- 1 root wheel 24576 Oct 27 13:00:01 2008 __db.001 -rw------- 1 root wheel 57344 Oct 27 13:00:01 2008 __db.002 -rw------- 1 root wheel 270336 Oct 27 13:00:01 2008 __db.003 -rw------- 1 root wheel 98304 Oct 27 13:00:01 2008 __db.004 -rw------- 1 root wheel 49152 Oct 27 13:00:01 2008 __db.005 -rw------- 1 root wheel 32768 Oct 26 19:47:37 2008 expire.db -rw------- 1 root wheel 10485760 Oct 27 14:22:08 2008 log.0000000001 It contains the familiar BDB files, so I think it works, although the expire.db's modify time is yesterday, but deliver saved some messages also today to the spamassassin/SPAM folder. What could be the problem? Am I missing something? Thanks! Daniel -- LEVAI Daniel PGP key ID = 0x4AC0A4B1 Key fingerprint = D037 03B9 C12D D338 4412 2D83 1373 917A 4AC0 A4B1

[Dovecot] Problem with Dovecot 1.1.4 and dovecot-antispam 20080829

Hi there, I'm running a server under Gentoo 64 with postfix 2.5.5, Dovecot 1.1.4-r1 and Dovecot-antispam 20080829 (all are the lastest versions availables under Portage). I ran into a problem when I log in to my mailbox : Oct 30 10:39:23 ks29138 dovecot: IMAP(hiltg): Loading modules from directory: /usr/lib64/dovecot/imap Oct 30 10:39:23 ks29138 dovecot: IMAP(hiltg): Module is for different version 1.1.1: /usr/lib64/dovecot/imap/lib90_antispam_plugin.so Oct 30 10:39:23 ks29138 dovecot: Fatal: IMAP(hiltg): Couldn't load required plugins Is there another version for Dovecot 1.1.4 out there or must I go back to 1.1.1 ? Thanks, Guillaume

[Dovecot] Dovecot read only for users
by JC 31 Oct '08

31 Oct '08

All, I have hopefully a base question. How do you give users only read access to their inbox and folders? If I use chmod 600 they have full access. If I do a 400 they have read access but cannot access their inbox. The config file is the out of the box config other than advertising IMAP and IMAPS. Any help will be appreciated. Thanks.

Hi folks, I'm using the latest Dovecot 1.16 with Postfix for my FreeBSD box. Since v1.1.4 (if i remember correctly), the following message is displayed whenever starting Dovecot. "Info: If you have trouble with authentication failures, enable auth_debug setting. See http://wiki.dovecot.org/WhyDoesItNotWork" Besides that, Dovecot works great but I wonder what this message is all about. I've searched wiki and mailing list but didn't find anything related. PS: I removed Dovecot removing all stalled files and directories and reinstalled it from scratch. Still the message is displayed whenever it starts. Any idea? Athan

[Dovecot] SIGBART/SIGSEGV while SELECTing virtual folder
by Lars Noschinski 30 Oct '08

30 Oct '08

Hello! I just installed Dovecot's latest nightly build (20081020) and tried the virtual folder features. I started with a really simple "all" folder: | # virtual/all | * | all But selecting this folder causes dovecot to panic (in most cases). While trying to debug this, I got slightly different results and I am not really sure yet if this is just non-deterministic, depends on some cached dovecot data or if there is some difference between the debug build or my rudimentary, unpatched debian package (which lacks the debug symbols). The results below are from a build with --prefix set to a clean, temporary directory. Similar problems occured also with the alpha2 release, which caused me to try the latest nightly build. --------------------------------------------------------------------- % ./sbin/dovecot --exec-mail ext /usr/bin/gdb ./libexec/dovecot/imap GNU gdb 6.8-debian Copyright (C) 2008 Free Software Foundation, Inc.

[Dovecot] dovecot 1.1.5 mbox bug (From_-line separator related)

If I send mail with content like this: From <test.dovecot(a)m.box> Wed Jan 09 01:33:55 2008 From <test.dovecot(a)m.box> Wed Jan 09 01:33:55 2008 From <test.dovecot(a)m.box> Wed Jan 09 01:33:55 2008 From <test.dovecot(a)m.box> Wed Jan 09 01:33:55 2008 and instead single messages created many messages. Inside mbox file it looks like real_message_headers Status: O X-Keywords: Content-Length: 2859 X-UID: 1471 From <test.dovecot(a)m.box> Wed Jan 09 01:33:55 2008 X-UID: 1472 Status: O From <test.dovecot(a)m.box> Wed Jan 09 01:33:55 2008 X-UID: 1473 Status: O From <test.dovecot(a)m.box> Wed Jan 09 01:33:55 2008 X-UID: 1474 Status: O Yes, Content-Length headers present, but: 1. Why X-UID: and Status: headers inserted into message body? 2. Why IMAP client (thunderbird) show many empty messages instead single message? Mbox related settings from dovecot -n is only: mmap_disable: yes mbox_write_locks: fcntl mbox_min_index_size: 1024 To store messages used dovecot deliver. -- WBR, Anton Yuzhaninov

[Dovecot] mail_executable's process environment
by Mike Malsman 30 Oct '08

30 Oct '08

Hello, I recently had to get Dovecot 1.1.4 to write to a "pop3/imap-before- smtp" db such that my MTA could permit relay after a successful authentication with Dovecot. The 'pop3' and 'imap' processes are executed only after a successful auth, so replacing them with wrappers which write to the db seemed the natural choice. Lo and behold, someone thought of something like this, as the 'mail_executable' directive exists - neat. Upon inspection of the processes' environment I'm pleased to see that there's a load of useful information in there. However, one essential component in my case is the destination network address, which is missing. I added it with the attached patch, exposed as 'LOCAL_IP'. Works for me. Is this something that would be useful to anyone else? -Mike

[Dovecot] [dovecot] Enable logging of all client commands in dovecot-1.2.alpha3
by Jonathan Siegle 30 Oct '08

30 Oct '08

Hello, I would like to log all IMAP client commands sent to dovecot. The format would be time pid command arguments. I reviewed http://wiki.dovecot.org/Logging and started digging through dovecot-1.2.alpha3/src/master . I don't need this turned on all the time, just enough to see how clients do things and I don't need to see passwords. Any tips would be appreciated. -Jonathan

[Dovecot] benchmark dovecot
by Mathieu Kretchner 30 Oct '08

30 Oct '08

Hello, We would like to do a feed back to this active mailing list. We are working on a migration project from cyrus to dovecot. And we have just completed the benchmark sequence. As I say, this benchmark is here only to show that our old imap server is out to date. I would not be the source of controversy at all, so I try to explain my approach. Because the only thing I found was this old oriented benchmark : http://www.isode.com/whitepapers/mbox-benchmark.html We've tried to do our tests, here you could find our results : http://www-sop.inria.fr/members/Mathieu.Kretchner/dotclear/index.php/2008/1…

[Dovecot] Enh-Req: Mark As Read When Delivered
by Neil 30 Oct '08

30 Oct '08

I'm under the impression bug-reports are supposed to go to the list, so hopefully it's okay if I put in a feature request here too (assuming it's not already implemented; but it doesn't look like it). Basically, all I would like to do is be able to sometimes deliver mail as already mail into mail boxes. Is there some way to do this? If not, could a flag perhaps be added to deliver to do it? (And Sieve; but for now I think procmail still has much higher adoption, and thus having it in deliver would be rather key...) Thanks, -Neil.

[Dovecot] INBOX stored in AFS
by Hans-Werner Paulsen 30 Oct '08

30 Oct '08

Hello, currently we are storing the incoming mail in the user's home directory, which is within a distributed filesystem called AFS (OpenAFS). Accessing the "mbox" file directly (using the distributed filesystem) works fine with mutt, thunderbird, ... To access the INBOX from a machine, which does not have access to this distributed filesystem, we are using IMAP (UW-imap). Now I wanted to check if dovecot can do the job (maybe faster than UW), and I had the following problem: This is my configuration: ------------------------------------------------------------------------------- # 1.1.4: /opt/dovecot-1.1.4/etc/dovecot.conf log_path: /var/log/dovecot ssl_cert_file: /etc/ssl/certs/imapd.pem ssl_key_file: /etc/ssl/keys/imapd.pem login_dir: /var/run/dovecot/login login_executable: /opt/dovecot-1.1.4/libexec/dovecot/imap-login first_valid_uid: 100 mail_location: mbox:~/Mail:INBOX=~/.maildir/incoming mail_debug: yes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mbox_write_locks: fcntl mbox_dirty_syncs: no mbox_lazy_writes: no mail_executable: /opt/dovecot-1.1.4/libexec/dovecot/afs-token /opt/dovecot-1.1.4/libexec/dovecot/imap auth default: verbose: yes debug: yes passdb: driver: pam args: setcred=yes session=yes dovecot userdb: driver: passwd ------------------------------------------------------------------------------- When I start my imap-client, I see the content of the INBOX, and I can read, delete, ... the different entries. But when new mail arrives dovecot (and my imap-client) will never notice this. And when I quit my imap-client the dovecot imap server will write back its view of the INBOX, and delete this new mail. This seems to be a problem related to AFS. I poked in the dovecot code and have the following theory: dovecot opens the INBOX R/W, dovecot calls "stat" on the INBOX file periodically to look for modifications. But this does not work, because this machine will stat the local copy (AFS cache) of the INBOX as long as this file is still open R/W. My questions: Is it possible to have a configuration, that the INBOX file is not left open when stat-ing this file? Or is it possible to open the INBOX file R/W only when it us locked? Or is it necessary to modify the code?

[Dovecot] read only FS access
by Mathieu Kretchner 30 Oct '08

30 Oct '08

Hello, I would like to know if it's possible to subscribe to a folder that is on a read only File System ? We have a snapshot mechanism that create a .snapshot directly in the user folder. This is done by our NAS and we would like to give an access to this backup to our users. Thanks.

Re: [Dovecot] First release (v0.1.0) of the new Sieve implementation for Dovecot v1.2
by seriv＠parkheights.dyndns.org 30 Oct '08

30 Oct '08

Thank you Timo, it was my mistake. In 'plugin {}' section line 'sieve = /var/sievescripts/%n/sieve' worked for both cmusieve and sieve plugins. Command 'fileinto "INBOX/foo/bar"' with private namespace configuration you proposed - also worked in both plugins. I suspected that they have different behavior: cmusieve saved message into INBOX/foo/bar, while sieve - into foo/bar as in the deliver log I'm pasting here. But both messages were filed into the same mail folder. Difference in the logging, I think, is not a big problem. --- ls -l Maildir/.foo.bar/new total 8 -rw------- 1 seriv seriv 513 Oct 30 01:57 1225331850.M790093P1351.sisyphus.office.omniti.com,W=526 -rw------- 1 seriv seriv 518 Oct 30 01:59 1225331966.M468658P1400.sisyphus.office.omniti.com,W=531 tail -n 18 /var/log/deliver/dovecot-deliver.log --- deliver(seriv): Oct 30 01:57:30 Info: Loading modules from directory: /usr/lib64/dovecot/modules/lda/ deliver(seriv): Oct 30 01:57:30 Info: Module loaded: /usr/lib64/dovecot/modules/lda//lib90_cmusieve_plugin.so deliver(seriv): Oct 30 01:57:30 Info: Namespace: type=private, prefix=INBOX/, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes deliver(seriv): Oct 30 01:57:30 Info: maildir: root exists (/home/seriv/Maildir) deliver(seriv): Oct 30 01:57:30 Info: maildir++: root=/home/seriv/Maildir, index=, control=, inbox=/home/seriv/Maildir deliver(seriv): Oct 30 01:57:30 Info: cmusieve: Using sieve path: /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:57:30 Info: cmusieve: Executing script /var/sieve-scripts/seriv.sievec deliver(seriv): Oct 30 01:57:30 Info: Namespace INBOX/: Using permissions from /home/seriv/Maildir: mode=0644 gid=-1 deliver(seriv): Oct 30 01:57:30 Info: msgid=<20081030015649.B7936140A88(a)sisyphus.office.omniti.com>: saved mail to INBOX/foo/bar deliver(seriv): Oct 30 01:59:26 Info: Loading modules from directory: /usr/lib64/dovecot/modules/lda/ deliver(seriv): Oct 30 01:59:26 Info: Module loaded: /usr/lib64/dovecot/modules/lda//lib90_sieve_plugin.so deliver(seriv): Oct 30 01:59:26 Info: Namespace: type=private, prefix=INBOX/, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes deliver(seriv): Oct 30 01:59:26 Info: maildir: root exists (/home/seriv/Maildir) deliver(seriv): Oct 30 01:59:26 Info: maildir++: root=/home/seriv/Maildir, index=, control=, inbox=/home/seriv/Maildir deliver(seriv): Oct 30 01:59:26 Info: sieve: using sieve path: /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:59:26 Info: sieve: opening script /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:59:26 Info: sieve: executing compiled script /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:59:26 Info: sieve: msgid=<20081030015911.576FC140A88(a)sisyphus.office.omniti.com>: stored mail into mailbox 'foo/bar' -- WBR, Sergey Ivanov. ----- "Timo Sirainen" <tss(a)iki.fi> wrote: > On Wed, 2008-10-29 at 20:31 +0100, Stephan Bosch wrote: > > sergey ivanov schreef: > > > Hi Stephan, > > > Thank you for quick fix.

Did you try dovecot-sieve-1.1 with dovecot 1.2 to verify? I'll ask Timo about this. What is the configuration of your mail store.

[Dovecot] FTS index generation
by Dave McGuire 30 Oct '08

30 Oct '08

Hi folks. I'm experimenting with the Squat plugin. I can execute search commands via direct interaction with IMAP, but I never see the expected dovecot.index.search index file appear in the spool. I'm concerned that I've misconfigured something that is preventing the creation of those indices. Is there a facility to have the squat plugin generate debugging messages so I can see what it's doing? Thanks, -Dave -- Dave McGuire Ahh, you voted for Bush? Port Charlotte, FL Happy now?

[Dovecot] Embedded "From<space>" Lines
by Lennart Lövstrand 29 Oct '08

29 Oct '08

Hi. As some of you may remember, I reported a problem a while back where dovecot 1.1.beta14 (as well as dovecot 1.0) would corrupt mbox-style mailboxes by ignoring the Content-Length header and breaking up messages with embededed "From<space>" lines. I recently downloaded Dovecot 1.1.5 and noted to my pleasure that this bug now has been fixed. That's great! This fix envolves checking to see if the expected_body_size (from the Content-Length header) is larger than the body_size produced by the "From<space>" scanner, and if so, if there is a valid "From<space>" line at the "expected" end of the message. However, I also noted that there's a case which the fix doesn't cover, and that's where the "From<space>" line appears as the first line of the body of the message. When this happens, the body_offset will point to the blank line between the headers and the body and not the actual first line of the body. This will cause the stream to be mispositioned at the time of the "From<space>" verification check in istream_raw_mbox_get_body_size and the (actually correct) expected_body_size will be rejected. I have enclosed a simple diff that will work around this by adjusting the body_offset to point to the next line at the time of call to istream_raw_mbox_is_valid_from in istream_raw_mbox_get_body_size. This appears to handle the problem correctly in all the test cases I have. To anyone else who has run into this problem and gotten corrupted mailboxes as a result, I can also offer an mbox checker that will attempt to detect and repair this problem in existing mailboxes as well as inspect them for other problems. I'm not ready to send it out for a full release yet, but interested beta testers are invited to contact me directly. Cheers, --Lennart

[Dovecot] quota warning not working

Hi all, I have finally get working the quota with dovecot. Now i am setting up the quota warning, with this in dovecot.conf: quota_warning = storage=70%% /usr/bin/quota_warning.sh 70 In the plugin section naturally. All seems to work fine, the quota is calculated right, but seems the script is not executed... In dovecot logs i have this: deliver(test(a)test.com): Oct 27 15:14:53 Info: Quota warning: bytes=10752000 (70%) messages=0 (0%) command=/usr/bin/quota_warning.sh 70 But...nothing happens. My quota_warning.sh is this: #!/bin/bash PERCENT=$1 echo "/usr/lib/dovecot/deliver -d "$USER" -c /usr/local/etc/dovecot-nowarning.conf" > /var/log/quotanotify cat << EOF | /usr/lib/dovecot/deliver -d "$USER" -c /usr/local/etc/dovecot-nowarning.conf From: postmaster(a)mediaservice.net Subject: quota warning Your mailbox is now $PERCENT% full. EOF I have added the echo for debug pourpose, but no file was created, so the script is not executed. I thinked is a permission problem, but seems not.

[Dovecot] Dovecot pop3 and SonicWall?
by Brandon Lamb 29 Oct '08

29 Oct '08

Hello Has anyone else run into a problem with dovecot pop3 and sonicwall? A week after switching to dovecot we had two local customers call and report they could no longer download emails with attachments. It turned out to be the email macro filter on the router. After the first report I thought maybe the customer had just changed something or it was a fluke, but then a day later we had the second call with the same issue. For some reason, after us switching the sonicwall's email macro filter was catching any attachments as a threat. I couldnt see how changing pop3 servers could affect that, but I guess anything is possible. I just emailed sonicwall and am waiting for a response from them now as well. Hopefully maybe someone has heard of this before. Unfortunately, I dont know if this was pure coincidence, or if both customers happened to have updated their sonicwall software, or maybe it autoupdates, I have no information on it.Of course to them it looks like we broke it. We just had them both turn this rule off for now.

[Dovecot] Dovecot and quota enforcement - only reporting?
by dovecot＠corwyn.net 29 Oct '08

29 Oct '08

I'm currently setting up postfix and dovecot with virtual users (mysql), imap, and quotas. I'm setting the quotas using mysql. I have quotas working correctly, and I can telnet into the imap server, and submit . getquotaroot inbox and get back valid quota information. I get a maildirsize file in the Maildir directory. Very cool. When I delete mail and expunge it, the quota updates. However, inbound email doesn't appear to update the quota. Two questions, probably related: What causes the quota (which I presume is the maildirsize file) to update? Is there any actual quota enforcement, or just reporting? Because if I send mail to an account, even if it currently reporting (via maildirsize or . getquotaroot) that the user is over quota, they still can send and receive email. Thanks!

[Dovecot] Authentication Error Message formats
by Albert E. Whale 29 Oct '08

29 Oct '08

I have been using UW's IMAP server and I am converting to Dovecot for Maildir support. When a user fails authentication, or a user does not exist, it appears that the same message is used for these events. Is there a way to indicate that the user does not exist (Invalid user), and authentication Failure (Failed Password)? Clearly these two failures indicate a different error in the system. One that some forgot their password, the other indicates a dictionary attack. -- Albert E.

[Dovecot] Empty/corrupt mail leads to duplicate delivery
by Marc Herbrechter 29 Oct '08

29 Oct '08

Hi, when the attached mail was stored in a maildir, fetching mail via POP3 lead to multiple delivery of mails in that maildir to the client (Outlook). I replaced the domain with dots. This is the dovecot configuration: --snip-- protocols = imap imaps pop3 pop3s listen = * disable_plaintext_auth = no ssl_cert_file = /etc/ssl/dovecot/server.pem ssl_key_file = /etc/ssl/dovecot/server.key mail_location = maildir:~/.maildir protocol pop3 { pop3_uidl_format = %08Xu%08Xv } auth default { mechanisms = plain passdb pam { args = "*" } userdb passwd { } user = root socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } --snip-- Version: dovecot-1.1.4-r1 (Gentoo) Gentoo applies the attached "expire" patch. I tried to reproduce the behavior, but when I send an empty mail via telnet, nothing happens. The box is running Amavis, don't know if that helps. -- Mit freundlichen Grüßen, with kind regards, Marc Herbrechter <mh(a)zebroc.de>

[Dovecot] Keep the email on the server
by Rubens A. Mascari 29 Oct '08

29 Oct '08

Hello, I migrate my server POP3/IMAP recently the Courier-IMAP for Dovecot and am having problems when the user configures your e-mail client to leave a copy of mail on the server. All mail in the inbox, are brought all the time that you check your mailbox input via POP3, causing a large traffic of unnecessary data every time. In my opinion you should bring only the new mail, unread. Can you tell me if this is a configuration issue on Dovecot? Thank you all -- Att.

[Dovecot] cannot use password-file for userdb
by Albert E. Whale 29 Oct '08

OK, I am attempting to use the userdb connection to facilitate per user migration to Maildir format from mbox. Here's the first user: more /home/dovecot.passwd health:$1$MCtvt/Tz$FmKqU/cbWlBhKnhc5W.Ko.:1152:1152:/home/health:userdb_mail=maildir:~/Maildir The configuration was set up as: userdb passwd { } I changed this to: userdb passwd-file { args = /home/dovecot.conf } And unfortunately the dovecot daemon dies after successfully launching.

Hello, just a quick question: if I want to use the autocreate plugin with 1.1.5, I have to compile it "by hand", right? How do I do that? Can I adapt a Makefile from another plugin? JC

[Dovecot] mbox to Maildir conversion
by Albert E. Whale 28 Oct '08

28 Oct '08

I've been running a mbox solution using UW's IMAP server. I've run it for years. Now do to heavy message volumes, I've decided to to take the plunge to convert to the Maildir format. I am currently testing a single user, and have successfully converted the mail messages from mbox to Maildir format, and now I am setting up the procmail tool to place the messages into the correct folder. I have been following the http://wiki.dovecot.org/Migration/MailFormat formula, but now have a question. New Messages are now being placed into the ~user/Maildir/new folder. However, when I attempt to retrieve those messages, Dovecot does not find them. Why not? -- Albert E.

[Dovecot] Possible header parsing problem
by Eric Stadtherr 28 Oct '08

28 Oct '08

Hi, I ran into a problem wherein my mail client (RoundCube) would not display a message from a Dovecot IMAP server (claiming that the message had no content). The raw source of the message looked fine, but the body structure returned by Dovecot only had the first text/plain part and not the alternative text/html part. The message looks like: ... headers removed ... X-Mailer: Lotus Notes Release 6.5.1 January 21, 2004 Message-ID: <...> From: user(a)host.domain Date: Mon, 20 Oct 2008 14:15:55 -0600 Content-Type: multipart/alternative; boundary="=_alternative 006F3A73872574E8_=" This is a multipart message in MIME format. --=_alternative 006F3A73872574E8_= Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=us-ascii blah blah blah --=_alternative 006F3A73872574E8_= Content-Transfer-Encoding: 7bit Content-Type: text/html; charset=us-ascii <br><font size=2 face="sans-serif">blah blah blah in HTML</font> --=_alternative 006F3A73872574E8_=-- I did a little bit of tracing through the parsing code (message-header-parser.c:message_parse_header_next()) and it appeared that the boundary in the Content-Type header was not parsed correctly, evidently because the header line was folded in the middle of the boundary string. RFC 822 appears to allow folding in a quoted string like this (§3.3 "quoted-string"), so I'm curious whether the parsing is working correctly. Thanks for your help! Here is my Dovecot information: version: 1.1.4 "dovecot -n" output: # 1.1.4: /usr/local/etc/dovecot.conf Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 384).

[Dovecot] Gah, pop3 falling over

27 Oct '08

Why would I be seeing a million of these? dovecot: 2008-10-27 09:12:33 Warning: chdir(/mail/mail/domain/u/username/) blocked for 18 secs Two servers were working fine and then all of a sudden this morning bam 500 load and theres a million dovecots and tons of these lines in the logs. It is like everyone gets up at exactly 8:30 and hits the pop3 server at once. Anyway, dovecot 1.1.5, nfs mount, debian lenny/sid amd64, 2.6.26-1-amd64 i had the performance mode options for login configured, i just set back to the single process per login though, I think that hasnt fallen over that way but I really dont remember anymore.

http://dovecot.org/releases/1.1/dovecot-1.1.5.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.5.tar.gz.sig http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha3.tar.gz http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha3.tar.gz.sig A combined release announcement for a change. :) Largest changes since v1.1.4: * Dovecot prints an informational message about authentication problems at startup. The message goes away after the first successful authentication. This hopefully reduces the number of "Why doesn't my authentication work?" questions. + Maildir/dbox: Try harder to assign unique UIDVALIDITY values to mailboxes to avoid potential problems when recreating or renaming mailboxes. The UIDVALIDITY is tracked using dovecot-uidvalidity* files in the mail root directory. + Many logging improvements - In some conditions Dovecot could have stopped using existing cache file and never used it again until it was deleted. - pop3 + Maildir: Make sure virtual sizes are always written to dovecot-uidlist. This way if the indexes are lost Dovecot will never do a huge amount of work to recalculate them. - mbox: Fixed listing mailboxes in namespaces with prefix beginning with '~' or '/' (i.e. UW-IMAP compatibility namespaces didn't work). - dict quota: Don't crash when recalculating quota (when quota warnings enabled). - Fixes to handling "out of disk space/quota" failures. - Blocking passdbs/userdbs (e.g. PAM, MySQL) could have failed lookups sometimes when auth_worker_max_request_count was non-zero. - Fixed compiling with OpenBSD Largest changes since v1.2.alpha2: + Added userdb checkpassword (by Sascha Wilde) + Autocreate plugin: http://wiki.dovecot.org/Plugins/Autocreate + Listescape plugin: http://wiki.dovecot.org/Plugins/Listescape - All the same fixes as for v1.1.5 I was thinking about waiting for Kolab people's work for shared mailbox support to get done, get that code to v1.2 tree and then release v1.2.beta1 with feature freeze.

[Dovecot] Problems with the pop3 part of dovecot
by Brandon Lamb 27 Oct '08

27 Oct '08

Hello, I originally just typed up a 5 paragraph essay on my problems but just deleted it all. basically I need to find out where to start looking to find out what is the problem with my dovecot pop3 setup. I switched from courier imap/pop3 to dovecot imap/pop3. I have had super high loads (40+ and overnight one server went to 511) and its been a nightmare fighting with this new setup for the last two weeks. I did manage to narrow the problem down to it being with the pop3 part of dovecot. I am not sure why the load keeps going so high. The first week I attributed it to users having to redownload mail and reindex (we were aware of the UIDL problem), but two weeks later one of my machines overnight went to 511. I have changed so many config options to try to make it work that I have become overwhelmed and feel like I have tried everything to get the right settings. I am running four 64bit machines with amd 9850 cpus, 4 gigs ram, the mailstore is nfs mounted, the nfs server is using xfs. Debian lenny/sid. I dont know what to do, I am almost debating going back to courier pop3 and going through the week of support calls of customers downloading mail again but that is a last ditch effort. I can understand if i just need to wait it out while things are indexed for dovecot and stuff, but machines falling over and loads of 40 to 500 just for dovecot seems not right. so, where do I start?

[Dovecot] Problem with quota dovecot as lda and mysql
by Claudio Prono 27 Oct '08

27 Oct '08

Hello to all, That is my situation: I am trying to use dovecot as LDA with postfix, mysql e postfixadmin. So, all the users are stored in mysql, with quota password and all other things. All works properly, except for quota. I am trying to do some tests, but is not clear to me how to debug that problem. Scenario: user with 15 Mb of quota. That is my dovecot.conf (dovecot version 1.1.3 on OpenSuSE 11.0): dovecot -n # 1.1.3: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot-err.log info_log_path: /var/log/dovecot-inf.log protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login first_valid_uid: 51 last_valid_uid: 51 first_valid_gid: 51 last_valid_gid: 51 mail_location: maildir:/var/mail/virtual/%d/%u mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): outlook-idle imap_client_workarounds(imap): outlook-idle imap_client_workarounds(pop3): pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %Mf auth default: passdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 plugin: quota: maildir quota: maildir:user quota And this is my dovecot-mysql.conf: driver = mysql connect = host=127.0.0.1 port=3306 user=postfix password=XXXXXXXXXXX dbname=postfix default_pass_scheme = MD5-CRYPT password_query = SELECT username as user, password, '/var/mail/virtual/%d/%u' as userdb_home,'maildir:/var/mail/virtual/%d/%u' , 51 as userdb_uid, 51 as userdb_gid FROM mailbox WHERE username = '%n@%d' AND active = '1' user_query = SELECT maildir, 51 AS uid, 51 AS gid, concat('dirsize:storage=', ROUND( mailbox.quota / 1024 ) ) AS quota FROM mailbox WHERE username = '%u' AND active = '1' But.. when i send a mail that "overquota" the mailbox, nothing happens, the mail is normally delivered to maildir and the quota is not considered.

[Dovecot] Bug? auth(default) Authentication client gave a PID of existing connection
by Brandon Lamb 26 Oct '08

26 Oct '08

Hello, My first time on this list, just switched from courier imap/pop3 system to dovecot. Imap part is great, pop3 seems to suffer, been fighting it for a week. Anyway, the reason for this post is that I have seen these pop up in my logs, and on one of my mailheads there were some 50 lines of this dovecot: 2008-10-26 09:33:54 Error: auth(default): BUG: Authentication client gave a PID 15661 of existing connection Is this really a bug or anything to be concerned with? I just installed 1.1.5. I am using Debian lenny/sid on amd64, phenom 9850 4g ram, nfs mounted maildir format xfs storage.

[Dovecot] Dovecot dies with PAM error?
by Jason Walton 26 Oct '08

Just setup a new server on the weekend with Ubuntu 8.10 beta, and Dovecot 1.1.4. Every now and then, the IMAP server dies, and won't let users authenticate. It happens about once or twice a day. In /var/log/mail.log, you can see dovecot complaining about critial errors: Oct 21 14:46:16 tachikoma dovecot: imap-login: Login: user=<jason>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS Oct 21 14:46:16 tachikoma dovecot: IMAP(jason): Disconnected: Logged out bytes=769/9124 Oct 21 14:47:15 tachikoma dovecot: auth-worker(default): pam(jason,127.0.0.1): pam_start() failed: Critical error - immediate abort Oct 21 14:47:17 tachikoma dovecot: imap-login: Disconnected (auth failed, 1 attempts): user=<jason>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS If I have a look at /var/log/auth.log, I see: Oct 21 14:47:15 tachikoma dovecot-auth: PAM _pam_init_handlers: error reading /etc/pam.d/dovecot Oct 21 14:47:15 tachikoma dovecot-auth: PAM _pam_init_handlers: [Critical error - immediate abort] Oct 21 14:47:15 tachikoma dovecot-auth: PAM error reading PAM configuration file Oct 21 14:47:15 tachikoma dovecot-auth: PAM pam_start: failed to initialize handlers This sounds ominous. If I try to cat /etc/pam.d/dovecot, though, the file is obviously there: jason@tachikoma:/var/log$ cat /etc/pam.d/dovecot #%PAM-1.0 @include common-auth @include common-account @include common-session And restarting dovecot seems to fix the problem. Dovecot WAS running just fine, servicing mail all day long, and then suddenly it won't read the PAM config file, and then it won't let anyone log in until I log in and kill it. Any ideas? My IMAP client is either Thunderbird or Roundcube, if that's relevant.

[Dovecot] Bug in QRESYNC SELECT/EXAMINE behavior
by Michael M. Slusarz 24 Oct '08

24 Oct '08

RFC 5162 [3.1] states that a QRESYNC should return all changes in a SELECT/EXAMINE since the given modseq. In the following case, it looks like there is an off-by-1 error somewhere: C: A64 SELECT "TestMailboxTest" (QRESYNC (1224531494 6 1,3:5)) [MMS: MODSEQ given is 6] S: * OK [CLOSED] S: * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) S: * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. S: * 4 EXISTS S: * 0 RECENT S: * OK [UNSEEN 1] First unseen. S: * OK [UIDVALIDITY 1224531494] UIDs valid S: * OK [UIDNEXT 6] Predicted next UID S: * OK [HIGHESTMODSEQ 6] [MMS: HIGHESTMODSEQ is 6 - the same as our cache, so there should be no need for an update] S: * 2 FETCH (MODSEQ (6) UID 3 FLAGS (\Deleted)) [MMS: ...but we get this FETCH that contains the MODSEQ ID of 6, which we have already told the server we are aware of] S: A64 OK [READ-WRITE] Select completed. In other words, I don't think that "2 FETCH ..." should be in the server response - it is duplicative information as to what is already cached on the client. michael

[Dovecot] service imaps.
by Mauro Sanna 24 Oct '08

24 Oct '08

In dovecot.conf protocol imaps is set to port 10943. ssl_listen = *:10943 The standard port for imaps is 993. So why it is set to 10943?

[Dovecot] dovecot 1.2: SEGV in acl plugin when selecting a shared mailbox
by Sascha Wilde 24 Oct '08

24 Oct '08

Hi Timo, there is a bug in the acl plugin (in head, _without_ our acl changes), which causes an segfault on selecting a shared folder. * OK [CAPABILITY ...] Dovecot ready. x login 1(a)example.com secret x OK [CAPABILITY ...] Logged in y select "users/2(a)example.com/INBOX/bla" - Peer has closed the GNUTLS connection The dovecot.log shows a segfault: [...] child 4507 (imap) killed with signal 11 This _only_ happens when the shared mailbox wasn't accessed in the same session by any other means like MYRIGHTS or LSUB (when subscribed). After doing one of those selecting works too... If it helps I can generate a gdb backtrace. cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

No, the protocol (IMAP/POP3) is irrelevant. The important part to note (and where I suspect your problem is) is that the folder, as far as your client (Thunderbird) is concerned, is "Maildir/", the "Maildir/ new/" directory is part of Maildir's internal format. That is to say, you should never be putting "Maildir/(new|cur|tmp)" as a mailbox name into a client, just "Maildir/". -N.

[Dovecot] ManageSieve v0.11.0 released for Dovecot 1.2.alpha3
by Stephan Bosch 24 Oct '08

24 Oct '08

Hello Dovecot users, I have composed a release of the ManageSieve service for Dovecot v1.2. I also added two new capabilities that were added to the ManageSieve specification. Just like the last few releases, this new release supports the new Sieve plugin already. Change Log v0.11.0 ------------------- * Upgraded to Dovecot v1.2 * Added support for new ManageSieve capabilities RENAME and NOOP * Moved sieve settings to plugin {} section of config file. Now the settings `sieve` and `sieve_dir` in the plugin section are used for both the Sieve plugin and the ManageSieve service, avoiding the posibility of accidental differences in configuration. Installation ------------ The full installation procedure and other relevant information regarding ManageSieve is supposed to be available on the Dovecot wiki: http://wiki.dovecot.org/ManageSieve However, the changes regarding the config file are not properly described there yet. Refer to the package's README file in stead. New release: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.0.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.0.tar.gz.s… I have released a new patch for Dovecot v1.2 as well: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.alpha3-managesieve-0.11.0.d… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.alpha3-managesieve-0.11.0.d… My public key (id: 3DFBB4F4) can be found at wwwkeys.pgp.net.

[Dovecot] logging IMAP username rather than UNIX username
by Dale Gallagher 23 Oct '08

23 Oct '08

Hi there I'd like to change my setup to log the _actual_ IMAP user's login, rather than the UNIX username. My system uses a virtual uid setup with qmail, where the mailboxes are owned by the 'vmail' user and authentication is via checkpassword using user%domain (ie email, just with % instead of @). So dovecot is recording _all_ logins as: imap-login: Login: user=<vmail>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured I have the following log format specified: login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c I have also tried: login_log_format_elements = user=<%n@%d> method=%m rip=%r lip=%l %c However, this results in a log file entry of: imap-login: Login: user=<vmail@>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured How do I configure dovecot to log the _actual_ username which the client supplies during authentication? Thanks Dale

[Dovecot] Dovecot returns the same UIDL for another message
by Alexander Shikoff 23 Oct '08

23 Oct '08

Hello, I have a serious problem with dovecot and mbox format. dovecot returns the same UIDL for new messages and as result some MUAs don't retrieve new mail. UIDs returned by UIDL command look like 000000*1c*49006cec And there is a moment when dovecot stops incrementing marked digits. In other words when new message arrive to mbox, UIDL command returns used UID. I'll show with example: 1. Send some message and try to retrieve UIDL via telnet: # echo test-mailbox-1 | mail -s Test-1 mbox(a)cu.kiev.ua # telnet pop3.cu.kiev.ua 10110 Trying 193.108.130.4... Connected to emx.itcons.net.ua.

[Dovecot] ManageSieve textual fronend wanted
by Edgar Fuß 23 Oct '08

23 Oct '08

Is there some simple textual frontend to the ManageSieve protocol somewhat easier to use than gnutls-cli? I.e. something to use like managesieve -u ef putscript myscript < /tmp/myscript Password: managesieve -u ef setactive myscript Password: simply doing the TLS authentication and length computation for me.

[Dovecot] dovecot 1.0 to 1.1 upgrade and filesystem separators
by Ian Thurlbeck 23 Oct '08

23 Oct '08

Dear All I have a test system where I am trying out 1.1.4 On the old 1.0rc6 (!) system I had edited: src/lib-storage/index/maildir/mail-storage.h to change: #define MAILDIR_FS_SEP ';' #define MAILDIR_FS_SEP_S ";" so I can get some mail folder hierarchy and '.'s in folder names - this all worked perfectly. Under 1.1.4 the MAILDIR_FS_SEP lines are no longer present. What is the current practice for doing what I was doing before ? Many thanks!

Can you reproduce it? I can't really see how it's crashing. Could you apply the attached patch, and also compile the lib/*.c and lib-mail/istream-header-filter.c without -O2 so the backtrace will be more usable? (I usually do it by removing -O2 from the subdirs' Makefile and then make clean + make in those subdirs.)

Thanks Jose, Yes in the advanced options on email clients there is always a place to put the root folder path or (some similar name) and on the old server I used ~/mail/ in all of the email clients (thunderbird, outlook, seamonkey etc) and that worked fine. Doing that on the new dovecot based server produces the effect I've described - a folder called mail visible at the same level as inbox and the other IMAP folders inside that. On the older imapd based server doing the same thing produced a view of inbox with no mail folder ... just the IMAP folders in it displayed at the same level as inbox.

[Dovecot] mail_location & NFS mounted home dirs
by Roger Hale 23 Oct '08

23 Oct '08

Hi, I'm fairly new to Dovecot, migrating from a POP-only system with /var/mail only mailboxes. I'm currently on version 1.0.10 on Solaris 10, but I don't think that's relevant to the question. I'm a little overwhelmed by the number of configuration options at the moment. I took the "standard" mail_location = mbox:~/mail:INBOX=/var/mail/%u setting in dovecot.conf. This mostly works fine, but home dirs are NFS mounted and in the event that an NFS server is down users cannot read their mail. This is the case even for users who only use POP. So, my question is, do folks on this list have good suggestions for optimum ways to deal with this so that users (perhaps only POP users) can read their mail independent of home directories being available? I think I can make something up, but I'd rather take a standard approach if there is one. If this has already been discussed I apologise - just point me to it as I didn't find it. Thx, Roger _________________________________________________________________ X Factor: latest video, features and more. Click here! http://clk.atdmt.com/GBL/go/115454063/direct/01/

[Dovecot] dovecot-deliver occasionally fails to deliver, leaving no clues
by Lucas Madar 22 Oct '08

22 Oct '08

Hello, I have a FreeBSD 7.1 x86 system using dovecot with postfix and a mysql user database. Everything works completely fine, except that on occasion dovecot-deliver fails. When postfix tries to redeliver the message in about 15 minutes, it succeeds. So this isn't a very big problem, just an annoying puzzle. Here's the postfix log. At first, I thought it could be a postfix delivery problem. Oct 17 00:36:22 xxxxxxx postfix/pipe[16017]: 41E581CC5B: to=<xxxx(a)xxxxx.xxx >, relay=dovecot, delay=0.04, delays=0. 01/0/0/0.03, dsn=4.3.0, status=deferred (temporary failure) I turned on delivery logging to see what I'd get, and I simply get this: deliver(xxxxxx(a)xxxxx.xxx): Oct 17 00:36:22 Info: Loading modules from directory: /usr/local/lib/dovecot/lda deliver(xxxxxx(a)xxxxx.xxx): Oct 17 00:36:22 Info: Module loaded: /usr/ local/lib/dovecot/lda/lib90_cmusieve_plugin.so (normally, here it would print out more info about the user, as "auth input" lines, but it doesn't when it fails in this way) Dovecot is not dumping core, or even printing out any error message that I can see. I have all logging turned on (except for passwords), and I still seem to get nothing. I've attached my dovecot -n output, which doesn't seem to contain the logging I have set up for deliver: log_path = /var/log/delivery.log info_log_path = /var/log/delivery.log mail_debug = yes auth_debug = yes auth_verbose = yes Any clue as to what could be going on here? Thanks, Lucas

[Dovecot] dovecot and postfix with tls and dovecot sasl issues for smtp clients
by Harondel J. Sibble 22 Oct '08

22 Oct '08

This issue is peripherally related to the following thread Re: [Dovecot] client certs with godaddy ssl cert This is running on CentOS 5.2 with latest Atrpms for Dovecot as of this weekend. # rpm -qa | grep dovecot dovecot-sieve-1.1.5-8.el5 dovecot-1.1.4-0_81.el5 With assistance from Rainer Frey (Inxmail GmbH), I am able to successfully use client ssl certs for imap access on both my Nokia e61i and Thunderbird 2.0.0.17, problem now is dovecot sasl and postfix smtp authentication. Using the same self created CA that generates and certifies the ssl client certs in Postfix and using Dovecot SASL, I always get client didn't send proper ssl cert when trying to do a tls based smtp connection from either the e61i or tbird.

[Dovecot] dovecot delivery log
by jalal 22 Oct '08

22 Oct '08

Trying to debug a delivery problem recently (with Postfix) and I realized that Dovecot wasn't logging any of the delivery information. I'm using Postfix to recieve mail, which is passing it on to Dovecot's deliver to actually deliver the emails into the mail boxes. In dovecot.conf, I have: protocol lda { log_path = /var/tmp/dovecot-deliver.log } [root]# dir /var/tmp/ total 2 drwxrwxrwt 2 root root 1024 Oct 22 12:30 . drwxr-xr-x 24 root root 1024 Aug 5 08:03 .. -rw------- 1 vmail vmail 0 Oct 22 12:11 dovecot-deliver.log The log file gets created OK, but then stays at zero size. Using: Postfix 2.3.3 Dovecot 1.1.4 (and previously 1.0.9) Any clues as to how I can have a delivery log?

[Dovecot] displaying IMAP folders that are in ~/mail/ at same level as inbox
by David London 22 Oct '08

22 Oct '08

Hi, We are moving our current IMAP based system to a new one with dovecot All I can get about the current IMAP (imapd) system is: IMAP4rev1 v12.264 dovecot version is: 1.0.rc15 In the existing system I can see IMAP folders that are in ~/mail/ with many mail clients (e.g. Thunderbird, Outlook, Seamonkey and horde). These folders are presented in the client software as being at the same level as the inbox - i.e. not inside the folder "mail" On the new system, horde webmail shows the other folders in ~/mail/ as being at the same level as the inbox. But ... all the other mail clients above now show a folder (directory) called mail with the imap folders inside. Is there some way to set this up so these other mail clients see the imap folders in ~/mail/ as being at the same level as the inbox as we have on the old server? Thanks, David _________________________________________________________________

[Dovecot] Permission issues with subscriptions
by Eric A. Bonney 22 Oct '08

22 Oct '08

I am having some permission issues with my setup and I can't see where to make the change in the configuration files. My users can not create folders at all from their email clients nor from the web interface. I have noticed that each time I try to create a folder the subscriptions files permissions are set to 000. If I go back and reset the permissions to rw-r--r-- then everything is fine until I try to add another folder. running dovecot -n produces the following: # 1.0.10: /etc/dovecot/dovecot.conf listen: [::] login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 1000 default_mail_env: maildir:/mnt/hd4/MailBoxes/%d/%n mail_location: maildir:/mnt/hd4/MailBoxes/%d/%n umask: 511 auth default: user: nobody passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch I am guessing that Dovecot is the actual process that is creating the folders on the IMAP server, so where inside the configuration file do I set the permissions for the new folders along with the user and groups? Thanks, -Eric

[Dovecot] Proxying pop3 sessions into an imap one.
by Diego Liziero 22 Oct '08

22 Oct '08

I know it seems at least unusual. But I would like to know if someone knows a software that can proxy multiple pop3 and imap connections to the same account and use only imap connections to the real server. I need it because I've to deal with two pieces of software that are out of my control: - 1 - A certified mail provider that states something that I would like to know if it's really true, or if it's worth keeping like a funny signature: "multiple imap sessions are possible. When an imap session is active, no pop3 connections are possible on the same account; when no imap connection is active, only one pop3 connection at a time is possible on the same account. This is a limitation of the pop3 protocol." - 2 - A software written to deal with certified mails that supports only pop3 used by many people on the same account, (and the same account is used also by multiple imap mail readers). Regards, Diego.

In dovecot 1.2 I can create a shared name space like this: namespace shared { separator = / prefix = users/%%u/ location = Maildir:/PATH/TO/spool/%%u/maildir:INDEX=/PATH/TO/spool/%u/maildir/shared_idx subscriptions = no } now, when I subscribe to a shared mailbox of another user with an dot in the users id, like: users/2(a)example.com/INBOX/foo and I list my subscribed mailboxes I get: l001 lsub "" "*" * LSUB () "/" "users/2@example/com/INBOX/foo" as you can see the dot in the user-id got normalized to the hierarchy seperator `/' -- which of cause is wrong. ;-) cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Reporting NFS quotas via IMAP
by Edgar Fuß 21 Oct '08

21 Oct '08

I'm confident that the question has been asked before, but I can't remember the answer. I have -- dovecot 1.1.2 -- Mail storage (maildir format) on NFS -- Quotas on that file system -- A working rquotad -- mail_plugins = quota imap_quota in the protocol imap section -- quota=fs in the plugin section I get (using Apple Mail as a client) -- Notification that the account supports quotas -- No information about the size of the quota nor the usage I probably do something stupidly wrong. The WIKI tells me that fs quota support RPC (i.e., rquotad), so I'd expect my client to report the quota to me. Using quota(1) on the mail server works as expected.

[Dovecot] Per user mail quota via LDAP
by Proskurin Kirill 21 Oct '08

21 Oct '08

Hello all. Ok im now trying to make per user quota via LDAP. In LDAP im have attr: mailQuotaSize=210 Default dovecot quota=201M I edit my static db to this(from wiki): userdb static { args = uid=1002 gid=1002 home=/var/spool/dovecot/domains/%d/%n mailQuotaSize=quota_rule=*:storage=%$M } But in logs I see this: Info: auth(default): master out: USER 5 sysadmin(a)domain.off uid=1002 gid=1002 home=/var/spool/dovecot/domains/domain.off/sysadmin mailQuotaSize=quota_rule=*:storage=M And personal quota not work. What I do wrong? -- Best regards, Proskurin Kirill

[Dovecot] Using allow_nets
by Guy 20 Oct '08

20 Oct '08

Hi, I'm wanting to implement allow_nets so that some users can be limited to only use webmail while others can use client or webmail access. Adding the sql to pull a list of IPs/ranges for webmail only users was easy enough. For the users that are allowed to access from anywhere, do I need to specify 0.0.0.0/0 or something or can I just let the sql query return a blank field? Thanks Guy -- Don't just do something...sit there!

[Dovecot] v1.1.5 release candidate
by Timo Sirainen 20 Oct '08

20 Oct '08

http://dovecot.org/tmp/dovecot-1.1.5-rc.tar.gz I thought about making v1.1.5 release today, but then thought maybe I'll make an RC instead since I did quite a lot of changes this weekend. So please try and see if there are any bugs left. I'll make the final release in a couple of days. The largest changes since v1.1.4: + Maildir/dbox: Try harder to assign unique UIDVALIDITY values to mailboxes to avoid potential problems when recreating or renaming mailboxes. The UIDVALIDITY is tracked using dovecot-uidvalidity* files in the mail root directory. + Many logging improvements - In some conditions Dovecot could have stopped using existing cache file and never used it again until it was deleted. - pop3 + Maildir: Make sure virtual sizes are always written to dovecot-uidlist. This way if the indexes are lost Dovecot will never do a huge amount of work to recalculate them. - mbox: Fixed listing mailboxes in namespaces with prefix beginning with '~' or '/' (i.e. UW-IMAP compatibility namespaces didn't work). - dict quota: Don't crash when recalculating quota (when quota warnings enabled). - Fixes to handling "out of disk space/quota" failures. - Fixed compiling with OpenBSD

[Dovecot] NFS quota: hard or soft
by Edgar Fuß 20 Oct '08

20 Oct '08

Yes. I could spend more time testing this myself or examining the code. It looks to me that, with fs quota, dovecot refuses to store a mail (e.g. when the client moves a mail from one IMAP folder to another) if the user is beyond his soft limit. Is this correct/intended? Knowing nothing about the IMAP Quota extension, I would have expected that being in grace was OK. At least, this is what would happen if dovecot wasn't quota aware and the file system would enforce the limits.

[Dovecot] Sendmail and deliver LDA exits with EX_TEMPFAIL on overquota
by Sotiris Tsimbonis 20 Oct '08

20 Oct '08

Hi all, I have setup dovecot 1.1.4 and sendmail 8.14.3 with dovecot LDA on linux (RHEL5 on x86_64). I have deliberately set a very low quota (4MB) on a test account, while the actual disk usage is 5MB at the moment, in order to test overquota behaviour.. When I send an email to this account, sendmail accepts the email and tries to deliver it. Deliver fails to save in INBOX and returns an error, but the email stays in sendmail's queue.. Any suggestions on how to avoid this and produce a 5xx error for overquota users before accepting the email would be greatly appreciated..

[Dovecot] workaround for shared maildirs
by Giuliano Gavazzi 19 Oct '08

19 Oct '08

Hello, this is my first post to the list. I have several mailservers running courier-imap, but am planning to convert one (and maybe more) to dovecot 1.1.4. In the process I am also looking to finally implement shared maildirs. As it is well known some clients (notable Apple's Mail) have problems in showing shared folders if the correct private namespace (INBOX) is set in the client, as only folders beneath the INBOX root are displayed. I have seen some solutions proposed, but none satisfactory. As the problem stems in the invisibility of secondary namespaces from Mail.app, I though that tricking the namespace prefix to push the shared mailboxes inside the private INBOX namespace could be a solution and tried the following: namespace public { separator = . prefix = INBOX.Public. inbox = no location = maildir:/SharedMaildirs/Public:CONTROL=~/Maildir/ control/Public:INDEX=~/Maildir/index/Public hidden = yes list = yes subscriptions = yes } note the bogus INBOX.Public prefix. Note also that CONTROL might be better not set as this is a Maildir (see Keyword sharing in http://wiki.dovecot.org/SharedMailboxes) Initially I had defined an additional public namespace with the same maildir and a normal prefix, but this seems not necessary. Well, after some tests from Thunderbird, Mail and cone (yes, the courier UA) I can say it works . Still have to check Outlook and Opera, but this is encouraging. As the public namespace Public is actually contained inside the private (INBOX), as if it was a private mailbox (with no messages) called Public, it is actually possible to create such a mailbox inside INBOX and end up with a private mailbox called Public containing private messages AND public mailboxes... Any mailbox that a user creats inside Public instead, will end up being a public mailbox as expected. Thanks or any comments. Giuliano

[Dovecot] regarding dovecot.index.cache
by Dhaval Thakar 19 Oct '08

19 Oct '08

Hi, This is regarding updating dovecot.index.cache. I have few backup ids configured. these are used only when old mail needs to be retrieved. usually these mailboxes contains more then 9,000 mails. while login to webmail, imap consumption is high, which creates performance related issues for regular mailboxes. to resolve this i have to move heavy mailbox to dedicated server. before doing that, I wanted to confirm if there any way to update dovecot.index.cache even if user is not checking his / her mails. kindly confirm, & provide direction to implement same. Following is the mailserver related details Qmail with Vpopmail 5.4.24 Dovecot-1.1.4 dovecot -n # 1.1.4: /etc/dovecot/dovecot.conf protocols: imap ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_plugins: quota imap_quota trash imap_client_workarounds: delay-newmail outlook-idle namespace: type: private prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: mechanisms: plain login verbose: yes debug: yes debug_passwords: yes passdb: driver: checkpassword args: /home/vpopmail/bin/vchkpw userdb: driver: vpopmail userdb: driver: prefetch plugin: quota: maildir quota_rule: Trash:ignore thanks & regards dhaval

[Dovecot] Dovecot 1.1.4 / Maildir++ quota and move to trash
by Xavier Beaudouin 18 Oct '08

18 Oct '08

Hello, Seems there is some nasty problems with Dovecot 1.1.4... We use Maildir++ quota, and when moving mail to Trash, Dovecot just drop the connection... when the maildir is overquota. Is there any way to avoid that and just move the mail to the trash allowing user to expunge their mail easily without calling support to do rm -rf Maildir/cur ? Thanks, /Xavier

The most recent spate that we saw were as follows (in context, in case any of the other log messages may be relevant): Oct 10 04:48:45 alcor dovecot: pop3-login: Disconnected (no auth attempts): [9703], NNN.NNN.NNN.NNN Oct 10 04:48:45 alcor dovecot: pop3-login: Disconnected (no auth attempts): [9705], NNN.NNN.NNN.NNN Oct 10 04:48:45 alcor dovecot: pop3-login: Disconnected (no auth attempts): [9702], NNN.NNN.NNN.NNN Oct 10 04:48:46 alcor dovecot: pop3-login: Disconnected (no auth attempts): [9704], NNN.NNN.NNN.NNN Oct 10 04:48:46 alcor dovecot: pop3-login: Disconnected: Inactivity (auth failed, 1 attempts): [9500], USER10, NNN.NNN.NNN.NNN Oct 10 04:48:46 alcor dovecot: Panic: pop3-login: file client-authenticate.c: line 163 (sasl_callback): assertion failed: (!client->destroyed || reply == SASL_SERVER_REPLY_CLIENT_ERROR || reply == SASL_SERVER_REPLY_MASTER_FAILED) Oct 10 04:48:46 alcor dovecot: imap-login: Disconnected: Inactivity (auth failed, 1 attempts): [9502], USER11, NNN.NNN.NNN.NNN, TLS Oct 10 04:48:46 alcor dovecot: Panic: imap-login: file client-authenticate.c: line 200 (sasl_callback): assertion failed: (!client->destroyed || reply == SASL_SERVER_REPLY_CLIENT_ERROR || reply == SASL_SERVER_REPLY_MASTER_FAILED) Oct 10 04:48:46 alcor dovecot: imap-login: Disconnected: Inactivity (auth failed, 1 attempts): [9503], USER12, NNN.NNN.NNN.NNN, TLS Oct 10 04:48:46 alcor dovecot: Panic: imap-login: file client-authenticate.c: line 200 (sasl_callback): assertion failed: (!client->destroyed || reply == SASL_SERVER_REPLY_CLIENT_ERROR || reply == SASL_SERVER_REPLY_MASTER_FAILED) Oct 10 04:48:46 alcor dovecot: imap-login: Disconnected: Inactivity (auth failed, 1 attempts): [8777], USER9, NNN.NNN.NNN.NNN Oct 10 04:48:46 alcor dovecot: Panic: imap-login: file client-authenticate.c: line 200 (sasl_callback): assertion failed: (!client->destroyed || reply == SASL_SERVER_REPLY_CLIENT_ERROR || reply == SASL_SERVER_REPLY_MASTER_FAILED) Oct 10 04:48:47 alcor dovecot: imap[4258] USER8, 67.223.74.40: Disconnected: Logged out bytes=7407/20930 Oct 10 04:48:47 alcor dovecot: pop3-login: Disconnected: Inactivity (auth failed, 1 attempts): [9575], USER13, NNN.NNN.NNN.NNN Oct 10 04:48:47 alcor dovecot: Panic: pop3-login: file client-authenticate.c: line 163 (sasl_callback): assertion failed: (!client->destroyed || reply == SASL_SERVER_REPLY_CLIENT_ERROR || reply == SASL_SERVER_REPLY_MASTER_FAILED) Oct 10 04:48:47 alcor dovecot: pop3-login: Disconnected: Inactivity (auth failed, 1 attempts): [9576], USER14, NNN.NNN.NNN.NNN Oct 10 04:48:47 alcor dovecot: Panic: pop3-login: file client-authenticate.c: line 163 (sasl_callback): assertion failed: (!client->destroyed || reply == SASL_SERVER_REPLY_CLIENT_ERROR || reply == SASL_SERVER_REPLY_MASTER_FAILED) Oct 10 04:48:47 alcor dovecot: auth(default): Master requested auth for nonexisting client 9498 Oct 10 04:48:47 alcor dovecot: auth(default): Master requested auth for nonexisting client 9500 Oct 10 04:48:47 alcor dovecot: auth(default): Master requested auth for nonexisting client 9499 Oct 10 04:48:47 alcor dovecot: auth(default): Master requested auth for nonexisting client 9502 Oct 10 04:48:47 alcor dovecot: auth(default): Master requested auth for nonexisting client 9503 Oct 10 04:48:47 alcor dovecot: auth(default): Master requested auth for nonexisting client 9575 Oct 10 04:48:47 alcor dovecot: auth(default): Master requested auth for nonexisting client 9576 Oct 10 04:48:47 alcor dovecot: auth(default): Master requested auth for nonexisting client 9174 Oct 10 04:48:47 alcor dovecot: imap[9809] USER9, 132.205.7.20: Connection closed bytes=0/0 Oct 10 04:48:47 alcor dovecot: imap-login: Disconnected: Inactivity (auth failed, 1 attempts): [9174], USER8, NNN.NNN.NNN.NNN, TLS Oct 10 04:48:47 alcor dovecot: Panic: imap-login: file client-authenticate.c: line 200 (sasl_callback): assertion failed: (!client->destroyed || reply == SASL_SERVER_REPLY_CLIENT_ERROR || reply == SASL_SERVER_REPLY_MASTER_FAILED) Oct 10 04:48:48 alcor dovecot: imap-login: Disconnected (no auth attempts): [9896], NNN.NNN.NNN.NNN Oct 10 04:48:48 alcor dovecot: imap-login: Disconnected (no auth attempts): [9895], NNN.NNN.NNN.NNN Oct 10 04:48:48 alcor dovecot: pop3-login: Disconnected (no auth attempts): [9893], NNN.NNN.NNN.NNN >> I missed this originally, but on reflection I notice in the logs that >> every time the "record size too small" error appears, inevitably the >> user involved is over disk quota and out of grace period.

Re: [Dovecot] Corrupted transaction log file / record size too small
by Steven Winikoff 18 Oct '08

18 Oct '08

>> I've been working around the problem by deleting the contents of >> ~user/.imap for affected users, but I'd really prefer to fix it >> properly. :-) Any suggestions would be gratefully received. > >I think this should get fixed by itself? Although the first login fails, >the next one should succeed. Yes, that's right. I didn't realize it at first, because we were also seeing other problems (eg assertion failure at line 39 of index-sync.c) which did require the index to be deleted. I've since made the following changes: 1) commented out the assertion at line 39 of index-sync.c (as per http://www.nabble.com/dovecot-panic-after-upgrade-1.0.15-to-1.1.2-td1909850…) 2) recompiled dovecot without optimization (ie, gcc -O0 instead of -O2) (as per http://www.mail-archive.com/dovecot@dovecot.org/msg12936.html) 3) reverted to using flock for file locking instead of fcntl (we'd been using flock with dovecot 1.0.10; 1.1.3 used fcntl by default in a couple of places, so I changed it back to see what would happen) After this, we've seen fewer problems, but there are still the occasional ones: - the original corrupted transaction log error which prompted this thread - we still see the occasional assertion failure at line 1091 of index-mail.c; this is the one that I'd hoped to solve by recompiling without optimization, but at least it seems to be happening less frequently than before - this doesn't happen often, but once in a while we see assertion failures at line 163 of src/pop3-login/client-authenticate.c or line 200 of src/imap-login/client-authenticate.c >Can you reproduce this by running imaptest (on a test account)? >http://imapwiki.org/ImapTest Actually this and your other suggestions may not be necessary; I think I just realized what's been going on. I missed this originally, but on reflection I notice in the logs that every time the "record size too small" error appears, inevitably the user involved is over disk quota and out of grace period. For example, Oct 3 17:52:21 alcor dovecot: imap[14973] XXXX, NNN.NNN.NN.NNN: Corrupted transaction log file /home/XXXX/mail/.imap/sent-mail/dovecot.index.log: record size too small (type=0xcd91, offset=8180, size=0) Oct 3 17:52:21 alcor dovecot: imap[14973] XXXX, NNN.NNN.NN.NNN: fscking index file (in-memory index) Oct 3 17:52:21 alcor dovecot: imap[14973] XXXX, NNN.NNN.NN.NNN: Transaction log got desynced for index (in-memory index) Oct 3 17:52:21 alcor dovecot: imap[14973] XXXX, NNN.NNN.NN.NNN: Disconnected: IMAP session state is inconsistent, please relogin. bytes=169/1848 Oct 3 17:52:22 alcor dovecot: imap-login: Login: [14998], XXXX, NNN.NNN.NN.NNN Oct 3 17:52:22 alcor dovecot: wrapper[15023]: imap, XXXX, NNN.NNN.NN.NNN Oct 3 17:52:22 alcor dovecot: imap[15023] XXXX, NNN.NNN.NN.NNN: open(/home/XXXX/mail/.imap/CFI-Howe/.temp.alcor.15023.e786c194b1dcc08c) failed: Disk quota exceeded Having seen this, I went back to the saved log for September 30th (the one containing the excerpt I pasted into my original message in this thread) -- and interestingly, I found that the quota failure wasn't recorded there. I don't know what was different about that occurrence, but everything I've seen recently suggests that "record size too small" is due to interaction with the quota system. ...so this is where I admit that I have indeed read http://wiki.dovecot.org/Quota/FS; unfortunately, the only user-writable file system on this machine that doesn't have (or need to have!) disk quotas enabled is /var/tmp, which doesn't seem to be a suitable place for dovecot indexes. Under the circumstances, are you still interested in seeing ImapTest results and a backtrace? If so, should I do that before or after upgrading to 1.1.4?

[Dovecot] Request for help with new plugin
by John Lightsey 18 Oct '08

18 Oct '08

Hi there, I was having lots of trouble with the normal expire plugin so I decided to try and come up with a plugin that handles the trash directory in the same way as Courier (when the user logs out it should clean messages from the trash that have been there for more than X days.) I used the expire and trash plugins as a guide but there are probably a number of things done wrong here and I have plenty of questions. To use this you'd need to run autoreconf for the autotools scripts, compile, make, make install, then add "autoexpire" to the imap/pop3 mail_plugins lists and "autoexpire = Trash 7" to the plugin section. 1. Is there any documentation of how the hook system and virtual mailboxes work outside of the source code? 2. I'd like the Trash cleanup to occur at logout, but the closest I could find was mailbox close. This makes the behavior a little quirky. It seems like Dovecot closes the mailbox each time it performs an operation on it, so when the client gets a list of mail in the box it does a close and the oldest items in the returned list will actually be expunged. 3. Is SAVE_DATE the correct field to be looking for here? I want the expiration to be based on the amount of time the letter has spent in the trash folder. 4. For searching through the Trash folder, SEARCH_BEFORE doesn't seem to match up with SAVE_DATE. Is there some other way to limit the search results to the dates that will fall before a certain SAVE_DATE value? J.D.

[Dovecot] deliver not picking up INDEX setting?
by Tim Bishop 18 Oct '08

18 Oct '08

I'm using the post-login script approach to give more customisation to where our users can store their mail. It detects the location and type of the mailbox at runtime and passes it through using the environment to imapd. This works great. However, I can't seem to make deliver do the same. I pass it the same MAIL and NAMESPACE settings in the environment: MAIL=maildir:/home/cur/tdb/Maildir:INDEX=/var/state/dovecot-indexes/tdb NAMESPACE_1=maildir:/home/cur/tdb/Maildir:INDEX=/var/state/dovecot-indexes/tdb NAMESPACE_1_INBOX=1 NAMESPACE_1_LIST=1 NAMESPACE_1_PREFIX=INBOX. NAMESPACE_1_SEP=. NAMESPACE_1_SUBSCRIPTIONS=1 NAMESPACE_1_TYPE=private (plus some others set by my MTA) So INDEX appears to be set correctly. deliver does correctly pick up the mailbox location and has no trouble delivering mail, but the indexes are put in the Maildir directory and not under the indexes directory. Is it possible to make deliver respect the INDEX setting? Thanks, Tim. -- Tim Bishop http://www.bishnet.net/tim/ PGP Key: 0x5AE7D984

[Dovecot] Multiple maildirs
by Vassilis Vatikiotis 17 Oct '08

17 Oct '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Is is possible to specify multiple maildir location in mail_location? (default_mail_env in my case since I'm using version 1.0.rc15/debian etch). What I want to achieve is receive mail in /var/spool/mail, which is going to contain 1 Maildir per user, and have /home/%u/Maildir/ to store (move) messages from spool location. Postfix is taking care of the 1st (delivery in maildir format in spool location), and dovecot should (I want to) be able to read messages from both locations. Ideally, is something like: default_mail_env = maildir:/var/spool/mail:/home/%u/Maildir possible? thx -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFI9MEcgUWLzP4xLCERAoLKAJ4ySsAfIKDqIenmww1sTApcjikM3wCeIBA1 vO0glRfNXUtajKMaPYHM8L4= =eL+3 -----END PGP SIGNATURE-----

[Dovecot] Problem with namespaces
by Tim Bishop 16 Oct '08

16 Oct '08

[1.1.4 with http://hg.dovecot.org/dovecot-1.1/rev/b61424a50786 applied] I'm trying to use namespaces as described here for UW-IMAP compatibility: http://wiki.dovecot.org/Namespaces But I'm getting a problem with the hidden namespaces showing up in the LIST output. Here is a simplified transcript. The ~/Mail folder contains just two folders. The config given to imapd is as follows: MAIL=mbox:/home/cut/jru2/Mail:INBOX=/home/cut/jru2/.mail:INDEX=/var/state/dovecot-indexes/jru2 NAMESPACE_1=mbox:/home/cut/jru2/Mail:INBOX=/home/cut/jru2/.mail:INDEX=/var/state/dovecot-indexes/jru2 NAMESPACE_1_INBOX=1 NAMESPACE_1_LIST=1 NAMESPACE_1_PREFIX= NAMESPACE_1_SEP=/ NAMESPACE_1_SUBSCRIPTIONS=1 NAMESPACE_1_TYPE=private NAMESPACE_2=mbox:/home/cut/jru2/Mail:INBOX=/home/cut/jru2/.mail:INDEX=/var/state/dovecot-indexes/jru2 NAMESPACE_2_HIDDEN=1 NAMESPACE_2_LIST=0 NAMESPACE_2_PREFIX=mail/ NAMESPACE_2_SEP=/ NAMESPACE_2_SUBSCRIPTIONS=0 NAMESPACE_2_TYPE=private I would expect the second namespace not to be listed. But it is: in: 2 LIST "" "*" 3 LOGOUT out: * OK [RAWLOG TIMESTAMP] 2008-10-16 15:41:40 * LIST (\NoInferiors \UnMarked) "/" "folder" * LIST (\NoInferiors \UnMarked) "/" "test" * LIST (\NoInferiors \Marked) "/" "INBOX" * LIST (\Noselect \HasChildren) "/" "mail" * LIST (\NoInferiors \UnMarked) "/" "mail/folder" * LIST (\NoInferiors \UnMarked) "/" "mail/test" 2 OK List completed. * BYE Logging out 3 OK Logout completed. That's with hidden turned on, and the list option turned off. Am I missing something with my config? Tim. -- Tim Bishop http://www.bishnet.net/tim/ PGP Key: 0x5AE7D984

Can I have a master users list for each virtual domain?

[Dovecot] dovecot 1.2: dict no longer really support DICT_ITERATE_FLAG_RECURSE
by Bernhard Herzog 16 Oct '08

16 Oct '08

Hi, In dovecot 1.1, I could use DICT_ITERATE_FLAG_RECURSE when iterating over a dict to retrieve all entries that start with a given prefix. This doesn't seem to work anymore in the new dict implementation in dovecot 1.2. Looking at the SQL queries actually generated, it seems as if dovecot 1.1 used to generate queries that use pattern matching (key LIKE "my/prefix/%") whereas dovecot 1.2 does not, so it's no wonder that it doesn't work in 1.2. This probably has to do with the pattern matching for dict keys in the config file. It would be enough for my purposes at the moment -- i.e. getting the metadata plugin to work with dovecot 1.2 -- if recursion were only possible for the last of fields in the pattern.

[Dovecot] dovecot 1.1.4 maildir imap segfault in message_parse_header_next
by Diego Liziero 16 Oct '08

16 Oct '08

I've tried to stress test dovecot 1.1.4 with imaptest for days without any assertion failure or crash. Just some "got too little data" messages. So far it's the most stable 1.1.x version.

[Dovecot] deliver does not work with new shared namespaces in dovecot 1.2

Hi Timo, checking my new userdb-checkpassword back end is stumbled across the fact, that the new shared namespace definitions possible in dovecot stop deliver from working. The log says: Oct 15 14:37:43 burlywood3 <info> deliver(2(a)burlywood3.rgb)[24502]: Namespace: type=shared, prefix=users/%%u/, sep=/, inbox=no, hidden=no, list=no, subscriptions=no Oct 15 14:37:43 burlywood3 <error> deliver(2(a)burlywood3.rgb)[24502]: Namespace 'users/': shared: Shared namespace prefix contains unknown variables Oct 15 14:37:43 burlywood3 <critical> deliver(2(a)burlywood3.rgb)[24502]: Fatal: Namespace initialization failed I guess the primary (only?) case where these shared namespaces are needed for delivery is the use of sieve. cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Ignore prefix given by client?
by Tim Bishop 15 Oct '08

15 Oct '08

Hi all, I'm new to Dovecot, but so far I've been really impressed with what I've seen. I hope someone can help with the following question. We're migrating from a setup where some of our users use mbox with UW imap. The problem is we've never enforced a folder prefix, so some have their folders in ~/, others in ~/mail and others in ~/Mail. We've also got some users using maildir with Courier imap. I decided the easiest way to get this working transparently for the users was to use the post-login scripting approach. My script manages to locate the user's mail and sets MAIL accordingly. This all works a treat. The problem is when a user specifies their own prefix in their mail client (if it's blank there are no problems). If they have ~/Mail none of the folders show up. I've had a play with namespaces in an attempt to fix that, but it doesn't seem to be doing what I want. So my question is: is it possible for Dovecot to simply ignore the folder prefix given by the client? Thanks, Tim. -- Tim Bishop http://www.bishnet.net/tim/ PGP Key: 0x5AE7D984

[Dovecot] Multiple IMAP connections.
by Roderick A. Anderson 15 Oct '08

15 Oct '08

There is a project (catmail) to build a webmail front end using the Catalyst Framework and the question came up about multiple connections per user. Specifically the question was: "The IMAP server can support multiple connections, but do you think the backend should support multiple connections for separate folders or one IMAP connection for one session?" Since my servers are too low volume to have hit any kind of resource limits, and I believe Thunderbird mostly does the "Right Thing", I'm asking how you, that have higher volume systems, would prefer connections handled. Also I believe there was a thread, or two :-), on the way some of the other webmail programs handle connections. Not good? Thanks for all insights and suggestions. Rod --

[Dovecot] Bug: MODSEQ FETCH return (?)
by Michael M. Slusarz 15 Oct '08

15 Oct '08

Hi Timo - hope things are well :) Playing around with the CONDSTORE (RFC 4551) stuff while testing the IMAP lib I am writing and I think I have found a bug in Dovecot 1.2. RFC 4551 [4] identifies the FETCH response to a MODSEQ request as follows: fetch-mod-resp = "MODSEQ" SP "(" permsg-modsequence ")" with 'permsg-modsequence' defined as: permsg-modsequence = mod-sequence-value ;; per message mod-sequence Unfortunately, Dovecot 1.2 is returning as follows: S: * 1 FETCH (UID 1 MODSEQ 3 FLAGS (\Flagged \Deleted \Recent)) Where, under the RFC, I believe it should be: S: * 1 FETCH (UID 1 MODSEQ (3) FLAGS (\Flagged \Deleted \Recent)) Here is a proposed patch (WARNING: my C skills = zero): # HG changeset patch # User root(a)bigworm.curecanti.org # Date 1224040830 21600 # Branch HEAD # Node ID 0c0615bc6bf74ccf109049e251a30b8ab5f8ea67 # Parent 40df4d4cced09fa72d37581d0c526416d2c6e3de per RFC 4551, MODSEQ FETCH responses need to be wrapped in (). diff -r 40df4d4cced0 -r 0c0615bc6bf7 src/imap/imap-fetch.c --- a/src/imap/imap-fetch.c Tue Oct 14 14:52:44 2008 +0300 +++ b/src/imap/imap-fetch.c Tue Oct 14 21:20:30 2008 -0600 @@ -749,7 +749,7 @@ modseq = mail_get_modseq(mail); if (ctx->client->highest_fetch_modseq < modseq) ctx->client->highest_fetch_modseq = modseq; - str_printfa(ctx->cur_str, "MODSEQ %llu ", + str_printfa(ctx->cur_str, "MODSEQ (%llu) ", (unsigned long long)modseq); return 1; } Hope this helps/is correct. michael

[Dovecot] Search results as virtual folders
by Daniel L. Miller 15 Oct '08

15 Oct '08

This may have been asked before - if so I apologize. Some mail clients - like Thunderbird - can provide a virtual folder or "saved search" to provide a list of mails that match certain criteria. Obviously, unless special client-side caching is implemented - which Thunderbird (my own client of choice) - does not, generation of these folders take time. Does Dovecot have any provision for generating such virtual folders? Possibly as the result of a sieve script? -- Daniel

14 Oct '08

Greetings, I'm building a new 1.1.x-series Dovecot installation, and I have a problem setting up compatibility namespaces intended to handle old client-side settings. (See also: http://wiki.dovecot.org/Namespaces#head-0f3ab5ecab632eb517866c3508021e0605d…) I have produced a slightly cut-down example configuration which demonstrates the problem: # dovecot -n # 1.1.3: /etc/dovecot/dovecot.conf protocols: imap imaps pop3 pop3s ssl_cert_file(default): /etc/ssl/certs/imap.pem ssl_cert_file(imap): /etc/ssl/certs/imap.pem ssl_cert_file(pop3): /etc/ssl/certs/pop.pem ssl_key_file(default): /etc/ssl/private/imap.key ssl_key_file(imap): /etc/ssl/private/imap.key ssl_key_file(pop3): /etc/ssl/private/pop.key disable_plaintext_auth(default): yes disable_plaintext_auth(imap): yes disable_plaintext_auth(pop3): no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_max_processes_count: 1024 max_mail_processes: 32768 verbose_proctitle: yes first_valid_uid: 100 mail_privileged_group: mail mail_location: mbox:~/IMAP:INBOX=~/.email:INDEX=/data/dovecot-indexes/%1u/%u mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): zlib quota imap_quota mail_plugins(imap): zlib quota imap_quota mail_plugins(pop3): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): delay-newmail outlook-idle tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %08Xv%08Xu namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: private separator: / prefix: Mail/ location: mbox:~/Mail:INDEX=/data/dovecot-indexes/%1u/%u hidden: yes subscriptions: yes namespace: type: private separator: / prefix: ~/Mail/ location: mbox:~/Mail:INDEX=/data/dovecot-indexes/%1u/%u hidden: yes subscriptions: yes auth default: mechanisms: gssapi gss-spnego plain passdb: driver: pam userdb: driver: passwd plugin: quota: fs:Disk Quota Given this configuration, a Thunderbird client using a folder prefix of Mail/ is successfully able to enumerate (and access) non-INBOX folders: 5 list "" "Mail/%" * LIST (\Noselect \HasChildren) "/" "Mail/archive"^M * LIST (\NoInferiors \UnMarked) "/" "Mail/Trash"^M 5 OK List completed.^M 6 list "" "Mail/%/%" * LIST (\Noselect \HasChildren) "/" "Mail/archive/"^M * LIST (\NoInferiors \UnMarked) "/" "Mail/archive/INBOX-2008-10"^M * LIST (\NoInferiors \UnMarked) "/" "Mail/archive/INBOX-2008-09"^M [...] 6 OK List completed.^M 7 list "" "INBOX" * LIST (\NoInferiors \UnMarked) "/" "INBOX"^M 7 OK List completed.^M 8 list "" "Mail/archive" * LIST (\Noselect \HasChildren) "/" "Mail/archive"^M 8 OK List completed.^M ...

Through experimentation, it appears that Dovecot 1.1.x doesn't correctly handle namespaces that *begin* with the character '~'; using ~ in the middle of a prefix, e.g. "flibble~/Mail", worked as documented, leading me to suspect a bug in the ~-expansion handling of Dovecot. (Dovecot 1.0.x worked as expected in this configuration.) Unfortunately, an hg bisect run on recent Dovecot-1.1 versions didn't expose the offending commit that introduced this problem, so this bug (assuming it is a bug) was probably inadvertently introduced during the 1.1-development series. Can anyone suggest where in the source tree I should start looking to correct this behaviour? Cheers, David -- David McBride <dwm(a)tastycake.net>

[Dovecot] Get an extra_field in login process
by Alexandre Estanislau 14 Oct '08

14 Oct '08

Hi. I have an auth plugin where an extra_field is filled. Somewhere, in login process I need to log the authentication command and the extra_field, I was trying to do it in login-common/client-common.c, adding a new variable to login_log_format_elements and trying to get the fileld from environment, but, I could not find any way to do it, the getenv returns null everytime. Anyone can suggest something to do it ? Is there a way that I get the extra_fields from request in login process ?

[Dovecot] Multiple mailboxes per user
by spam＠wilysloth.com 13 Oct '08

13 Oct '08

My users currently have mail delivered to mulitple MailDir locations via procmail. ~/mail/inbox/ ~/mail/graph/ ~/mail/spam/ I would like all these mailboxes to be exported via dovecot IMAP and appear as folders. However, I can't anything beyond the INBOX working. My approach is via 'namespaces'.

However, selecting 'graph' I see: y:Exit c:Chdir m:Mask ?:Help 1 IMAP ../ ...I would have expected it to open the 'graph' MailDir mailbox and display the mail.

[Dovecot] client certs with godaddy ssl cert
by Harondel J. Sibble 13 Oct '08

13 Oct '08

I've read the client ssl cert section in the wiki and it talks about using a self signed cert, if I am using a commercial cert, in this case godaddy, how do I implement a self signed cert for the client side and have dovecot make use of this? I know the mechanics of setting up the self signed ca, the question is more what configuration changes do I need to make in dovecot to handle both godaddy and the self signed ca functionality?

[Dovecot] Can I translate the userid to match the UW-POP3 server?
by Albert E. Whale 12 Oct '08

12 Oct '08

OK, I have been running the UW-POP3 server which currently translates all login ids as lowercase (i.e. Anthony becomes anthony). Now the Dovecot server is very flexible and currently I have not found how to translate the upper case characters to lowercase. What configuration setting will translate the userids to lowercase? -- Albert E.

[Dovecot] Different authentication for pop3 and imap
by sh1ny 12 Oct '08

12 Oct '08

Is it possible to run different authentications for pop3 and imap ? What i need is to give access to some clients to pop3 only and to other to imap only. I'm using postgres as a backend. What i actually need is 2 separate queries for userdb, one to select with "WHERE imap_access = 1" and the other one with "WHERE pop3_access = 1" ( that's just an example ). I'm using 1.1.2 but i plan on upgrading to either 1.1.4 or 1.2.

[Dovecot] Password scheme module thoughts?
by Ian R. Justman 11 Oct '08

11 Oct '08

Hi, all. I have successfully deployed the code I wrote to handle Post.Office password hashes. However, I had to implement it as a hack to password-scheme.c. I'd like to implement it as a module so I don't have to hack Dovecot whenever a new release comes out. However, I had a few thoughts: 1. I used Dovecot's own MD5 routines in my implementation because I know how they behave. However, would it make sense to distribute the C sources for the MD5 routines, or would it make far more sense to have a Dovecot build tree already (so I can use Dovecot's function library)? 2. Is there good documentation for Dovecot's plugin API? I need it so I can figure out how to write the parts which the main program call so then the code can be used as a plugin. Thanks! --Ian. -- Ian R. Justman UNIX hacker. Anime fan. Any questions? ianj (at) ian-justman.com

Dear sirs Thank you and congratulations for creating Dovecot. When a message header is split along several lines, it seems only the first one is parsed by sieve. The following header: From: "=?iso-8859-1?Q?Cotiatododia=20-=20O=20Jornal=20de=20Not=EDcias=20a=20Se?= =?iso-8859-1?Q?rvi=E7o=20de=20Cotia=20e=20Regi=E3o=2E?=" <newsletter(a)cotiatododia.com.br> was not discarded by the following rule (when it should have been due to "cotiatododia"): if anyof (header :contains ["From", "Reply-To", "To", "Cc"] ["cotiatododia", "ganhedinheiro.com", "1000deaths.com", "ione.correia", "nsbezerra", "estudenoexterior.com", "pestana(a)mauriciopestana.com.br", "institutojairmoura2(a)gmail.com", "webmaster(a)ie.org.br", "jahgor(a)jahgor.com.br", "marketing(a)mirostur.com.br"], header :contains "Subject" "E ai!, Essa voce Tem que Ver!") { discard; } Thank you, Dennis

[Dovecot] Switching Servers now can't retrieve mail

10 Oct '08

I have just switched my mail server. I have copied (I think) the config files from the old to new. Exim is work fine on the new machine as I can see email file showing up in /var/mail/lists/new . However, dovecot reports nothing when I check mail . I am have turn on logging on both machines and I do not see anything that looks like an error. I have also looked to see if the dovecot.conf file is compatible between 1.0.14 and 1.1.2 and have found little. I am guessing this is a simple problem, can someone tell me what I have done wrong here. I have provided Working dovecot -n from both machines and the log output from a mail fetch.

Hello I have a user that experience troubles with it's pop3 client (eudora) at random time/hour the dovecot server refuse the connection to his machine during several minutes then it restart normally to download its emails ... the message is like the following : dovecot: Oct 09 15:36:35 Info: pop3-login: Internal login failure (auth failed, 1 attempts): user=<xxxxxxx>, method=PLAIN, rip=147.215.50.48, lip=147.215.1.3, TLS dovecot: Oct 09 15:41:35 Info: pop3-login: Internal login failure (auth failed, 1 attempts): user=<xxxxxxx>, method=PLAIN, rip=147.215.50.48, lip=147.215.1.3, TLS dovecot: Oct 09 15:46:35 Info: pop3-login: Internal login failure (auth failed, 1 attempts): user=<xxxxxxx>, method=PLAIN, rip=147.215.50.48, lip=147.215.1.3, TLS dovecot: Oct 09 15:51:35 Info: pop3-login: Internal login failure (auth failed, 1 attempts): user=<xxxxxxx>, method=PLAIN, rip=147.215.50.48, lip=147.215.1.3, TLS dovecot: Oct 09 15:56:35 Info: pop3-login: Internal login failure (auth failed, 1 attempts): user=<xxxxxxx>, method=PLAIN, rip=147.215.50.48, lip=147.215.1.3, TLS I run dovecot 1.1.4 (compiled on the machine) onto a debian etch 64 bits machine (IBM X3650) The passwd is memorized by the client so it is not a typo error of my (experienced) user who is a Computer science professor.

[Dovecot] maildri++ quota
by Ralf Hildebrandt 10 Oct '08

When is the maildir quota usages recalculated and written to the second line of the "maildirsize" file? I'm using 1.1.4, and I reset the quotas for my users by just taking the first line of their maildirsize file and deleting the rest. -- Ralf Hildebrandt (Ralf.Hildebrandt(a)charite.de) snickebo(a)charite.de Postfix - Einrichtung, Betrieb und Wartung Tel. +49 (0)30-450 570-155 http://www.arschkrebs.de I'm looking for a job "A man who won't die for something is not fit to live." -Martin Luther King, Jr.

[Dovecot] Test environment question
by Stewart Dean 09 Oct '08

09 Oct '08

My production DC machine owns the mail filesystems and is running DC V1.0.15 and mbox folder format. I am looking to test V1.1.3 on another machine, which NFS mounts the mail filesystems, but has its own local index FS. I have made this test environment my default connection in TBird, and it seems to work just fine. Also, I have made sure that my TBird client isn't connecting to the production server (it has multiple accounts but I have turned off the cehck for mail when starting and check for new mail every N minutes functions, and then check the ps table to make sure there are no imap connections) However, I'm seeing two errmsgs in the maillog on the test machine: > Sep 22 11:54:13 egg mail:err|error dovecot: IMAP(sdean): posix_fallocate() faile > d: Protocol not available > Sep 22 11:54:13 egg mail:err|error dovecot: IMAP(sdean): file_set_size() failed > with mbox file /var/spool/mail/sdean: Protocol not available which appear to happen AFTER mail arrives at the production server....it seems to happen on my test server the next time my client goes to access mail AFTER mail has arrived at the production server. Subsequent client requests of the test server execute without error until AFTER the next time mail arrives at and my inbox is updated with it. Again, if I hadn't looked at the logs, I wouldn't know there was a problem...I can see my new mail just fine from the test server. The questions: Is this anything I should be concerned about? Is this a bug or a legit problem coming from my improper use of two servers against the same data. FWIW, I am using fcntl for both mbox read and write locks. procmail in the MDA on the production server, and its locking hierarchy <dotlock,fcntl>, which Timo previously approved. Thanks!

[Dovecot] shared mailboxes in 1.2 question
by Robert Schetterer 09 Oct '08

09 Oct '08

Hi Timo, i tried a littel bit playing with shared mailboxes namespace shared { separator = / # %%u gets expanded to the remote user. Instead of %%u you can # also use %%n and %%d. prefix = "shared/" location = maildir:/usr/local/virtual/%d:CONTROL=/usr/local/virtual/%d:INDEX=/usr/local/virtual/%d inbox = no list = yes subscriptions = yes hidden = no } should at last show all other users mailboxes when .DEFAULT acl is authenticated lr and dovecot-acl in /usr/local/virtual/%d is authenticated lr too but instead only shared is shown in thunderbird playing with %%u etc in combinations does not lead to working results too (sometimes shared^^ was shown, might be user(a)domain.de isnt working for shared maildirs, @ could be a problem to maildir....?) your example was namespace shared { separator = / # %%u gets expanded to the remote user. Instead of %%u you can # also use %%n and %%d. prefix = shared/%%u/ location = Maildir:/home/%%u/Maildir:INDEX=~/Maildir/shared/%%u } so something with acl might not working in 1.2 and i think i need more explanation ( examples ...) in using %%u %%d ... to test shared mailboxes there were no usefull log entries which would give some more advice during testing...so it might be my fault and it only config stuff i didnt understand -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] Maildir size report for imap?
by Mark Zealey 09 Oct '08

09 Oct '08

Hi guys, It would be really nice if there were an easy way to see how much space an individual imap account used when a user logged out; something like pop3_logout_format = size=%s. I appreciate that this isn't so easy in imap though - I was thinking of using the quota plugin with no limit or something like that.

[Dovecot] 1.1.4 and trouble over NFS
by Igor Colombi 09 Oct '08

09 Oct '08

Hello, I have some trouble with the current setup (it's a testing environment): 2 server with Dovecot 1.1.4 from source (OS Debian testing 2.6.26) (name: "exim" and "exim2") 1 NFS server (OS Debian testing 2.6.26) I use NFS v.4, indexes shared over NFS. The relavant part of Dovecot configuration: dotlock_use_excl = yes mail_nfs_storage = yes mail_nfs_index = yes mmap_disable = yes lock_method = dotlock Maildir format. /etc/exports on NFS server: /mnt 192.168.0.0/24(rw,sync,no_root_squash,no_subtree_check,fsid=0) /mnt/vexim 192.168.0.0/24(rw,sync,no_root_squash,no_subtree_check) /etc/fstab on the clients: 192.168.0.71:/vexim /mnt/nfs1 nfs4 rw 0 0 When I access a mailbox with 2 different clients (for example Outlook Express that uses "exim" and Thunderbird that uses "exim2") and in the same time some message is delivered to the mailbox (the smtp is served by Exim 4.69) Dovecot has some trouble as you can see: *** Log from machine "exim" Oct 7 20:00:20 exim dovecot: IMAP(postmaster(a)minnie.tld):

safe. I can try to move indexes on the local disk, the trouble with dovecot.index disappear but I have again problem with dovecot-uidlist. I can reproduce this kind of problem easly: 2 clients on the same mailbox connected to two different imap server and a simple bash script that send 2 email every 1 second to the mailbox. There is some option/configuration that I can try to change?

[Dovecot] zlib plugin
by Luuk 09 Oct '08

09 Oct '08

hi, Could anyone give some info on this plugin? When i read the wiki (http://wiki.dovecot.org/Plugins/Zlib) i'm still left with some questions... I use Maildir to store my mails, if i enable this zlib-plugin, should i 'manually' compress all messages? or wil the uncompressed messages still be accessible by dovecot? wil new messages be compressed automagically? how should the compressed messages be named? a message now has the name '1223224520.2783_1.opensuse:2,S' how would a compressed message be named? ['1223224520.2783_1.opensuse:2,SZ' or '1223224520.2783_1.opensuse:2,S,Z' or ???] Last but not least, what gain will i have by using this plugin in combination with Maildir, or will it have more impact when mails are stored in mbox. -- Luuk $ dovecot --version dovecot version 1.1.1 $ uname -srpmio Linux 2.6.18.8-0.10-default x86_64 x86_64 x86_64 GNU/Linux

So now "Disable non webmail IMAP access" in vpopmail works fine!

[Dovecot] Folders within folders?
by ed beers 09 Oct '08

09 Oct '08

I'm trying to migrate my emails from an existing server (University of Washington IMAP toolkit) to dovecot. My clients are all using Thunderbird. I'm moving to a new Ubuntu based server (old one was Centos4) and selected dovecot solely because it was the default option. I'm not committed to it if it isn't the right tool for my application. My existing server allows hierarchical folders and these are used to organize 20 years worth of carefully sorted emails. I can create a new folders on the dovecot server but Thunderbird doesn't allow me to create new sub-folders within them. I think T-bird is configured OK since this works on the old server. Is this a dovecot limitation or have I configured it incorrectly?

[Dovecot] postfix/dovecot/mysql quotas not working, default dovecot.conf does.
by dovecot＠corwyn.net 08 Oct '08

08 Oct '08

I'm having problems getting dovecot to set imap quotas that are defined as individual quotas for virtual users using mysql. I'm using postfix/dovecot 1.1.3, just built from source about a week ago. I've been testing using telnet and getquotaroot. when I define the quota in dovecot.conf quota = dirsize quota_rule = *:storage=102400 I get the following response from Dovecot: # telnet 127.0.0.1 143 Connected to 127.0.0.1. * OK Dovecot ready. . login test222(a)example.com password . OK Logged in. . getquotaroot inbox * QUOTAROOT "inbox" "" * QUOTA "" (STORAGE 276273 102400) All is good (the mailbox IS currently very full as part of my testing). However, when I define that data in the dovecot-sql.conf file, it doesn't appear to pick the data up, either as an override, or, if I delete quota_rule = *:storage=102400 from dovecot.conf, I get no quota at all . getquotaroot inbox . OK No quota. # grep -v '^ *$#.*$\?$' dovecot-sql.conf driver = mysql connect = host=localhost dbname=postfix user=postfix password=password default_pass_scheme = MD5-CRYPT password_query = \ SELECT username, domain, password \ FROM mailbox WHERE username = '%u' AND domain = '%d' AND active = '1' user_query = \ SELECT 1015 as uid, 105 as gid, '/var/spool/mail/%d/%n' as home, \ 'maildir:/var/spool/mail/%d/%n/Maildir' as mail, \ 'dirsize' as quota, \ concat('*:storage=', quota, 'B') as quota_rule, \ FROM mailbox WHERE username = '%u' AND domain = '%d' and active = '1' the results remain the same in telnet. Any assistance would be appreciated. I've done a fair amount of digging, and have no idea why it's not working. ASsociated other configuration below. Thanks!

[Dovecot] Dovecot-sieve processing optimizations
by Roderick A. Anderson 08 Oct '08

08 Oct '08

I'm working at the next part of the virtual domains mail server. I'm moving this account (raanders(a)acm.org is a forwarder) which has a bunch of procmail rules to file into folders. My question is if it is more efficient is use? if { ... } elsif { ... } elsif { ... } else This seems to be the way many of the example scripts do it but I found at least one that used if { ... } if { ... } Which is more procmail like and for me reads easier. If not here where should I ask? Thanks, Rod --

So it's a bit less readable, I've to remember to disable sender restrictions in the content filter return transport to avoid filter loops, there will be one more line for each mail in the log stating that the filter is triggered, but apart from that it should work as I need. Thank you to everyone that helped me, tomorrow I'm going to test both methods. Regards, Diego.
