[Dovecot] Google Summer of Code
by Charles Marcus 13 Feb '09

13 Feb '09

On another list, someone wrote: > Google Summer of Code is on it's Way. Start collecting students to > throw at projects now! This sounds like a great idea for dovecot too... Timo, maybe there are a few dovecot enhancements that would be good candidates for this? Maybe the test suite? Replication? LMTP server? Anyway, its just a thought... -- Best regards, Charles

Re: [Dovecot] Mapping usernames [RESOLVED]

Resolved. For others, this is the simple solution which works for me: /etc/dovecot.conf: auth default { userdb passwd-file { args = /etc/passwd } passdb passwd-file { args = scheme="MD5-CRYPT" /etc/dovecot.passwd } } /etc/dovecot.passwd: bob@vhost.com:$1$yAOjs09l$...::::::userdb_user=vabc_bob (the encrypted password "$1$yAOjs09l$..." comes from /etc/shadow) /etc/passwd: vabc_bob:x:20838:2362:bob:/home/mailusers/vabc_bob:/sbin/nologin "abc" could also be the domain ("vhost"), but this might be too large for really long domain names. So we rather use a short unique prefix for each domain.

[Dovecot] file name missing component in error message
by Mike Abbott 13 Feb '09

13 Feb '09

Hi, we occasionally see this error message from maildir_mail_set_cache_corrupted(): "Maildir filename has wrong W value: %s/%s" but the path it prints is missing a component, specifically, the new/cur/tmp component. For example: /Volumes/Spool/user/maildir/12345.M123P123.example.com.... should be /Volumes/Spool/user/maildir/cur/12345.M123P123.example.com.... This is using dovecot-1.1.10. Now I just have to figure out why the file is corrupted in the first place.

[Dovecot] quota - implement via dovecot or postfix? which is easier ?
by Linux Advocate 13 Feb '09

13 Feb '09

Guys, i m new to dovecot. I m setting up a new mailserver and planning to run dovecot and postfix of a centos 5.2 box. I have been reading of quota management from various sources and understand that mail box quota can be implemented either thru postfix ( with vda patch ) or thru dovecot. i rather not patch postfix and m therefore leaning towards quota via dovecot. But after reading some posts ,etc, it seems that the information on the dovecot wiki is inaccurate. A.Any comments on this? B. Am i right in concluding that its easier and better in the long run to implement and enforce quotas thru dovecot instead of postfix? C. The right instructions for implementing quota thru dovecot? Regards, marco.

[Dovecot] Released Sieve v0.1.3 and ManageSieve v0.11.3 for Dovecot v1.2.beta1
by Stephan Bosch 13 Feb '09

13 Feb '09

Hello Dovecot users, It has been about two months since the last release of the new Sieve implementation and the ManageSieve service for Dovecot v1.2. Therefore, this release contains quite a few changes. It adds new sieve features like the enotify extension and multiscript support. Also, quite a few (user-reported) bugs were fixed since the last release. Changelog Sieve v0.1.3: * Adapted to changes in Dovecot, making this release dependent on Dovecot >= 1.2.beta1 * Made mail address comparison fully case-insensitive. This is particularly noticeable for the :addresses argument of the vacation command. + Finished enotify extension. Currently, only the mailto notification method is implemented. All still needs to be tested thoroughly. + Implemented multiscript support. It is now possible to execute multiple Sieve scripts sequentially. Administrator-controlled scripts can be executed before and after the user's script. Still needs to be tested thoroughly. + Implemented support for configuring the available Sieve extensions. + Made the subaddress extension (partially) configurable using the sieve_subaddress_sep setting, which allows specifying a (multi-charater) separator other than '+'. + Compiler now warns about invalid header field names used for the header and address tests. + Vacation extension now properly generates a References header for the response message. + Added testing of basic result execution to the test suite. Also added support for testing the outgoing messages produced by the Sieve interpreter. + Included execution of the actual result in the sieve-test command line tool. The undocumented sieve-exec tool that existed for this is now removed as planned. + Added support for the now obsolete 'imapflags' extension for backwards compatibility with CMUSieve. This also implements the mark/unmark commands. - Fixed bugs in the regex extension: 1) if an optional match value did not in fact match, subsequent match values would get unexpected indexes. 2) fixed segfault bug occuring when regex is freed. - Fixed bug in the use of the :from agrument for the vacation command. If this address included a phrase part, the response would not be a valid RFC822 message. - Plugged a theoretical security hole occuring when a directory is opened as a Sieve binary. - Cleaned up and fixed various log messages. - Fixed bug in the outgoing address verification. Addresses ending in ',' were erroneously accepted. Changelog ManageSieve v0.11.3: * Changed the SASL service name from "managesieve" into "sieve" as required in the protocol specification. Don't forget to adjust your configuration if your authentication mechanism depends on this service name. * Adapted to changes in Dovecot, making this release dependent on Dovecot >= v1.2.beta1. * Adapted to changes in the new Sieve implementation, making this release dependent on Dovecot Sieve >= v0.1.3 if used. The old cmusieve plugin is still supported. + Implemented making the SIEVE and NOTIFY capability fully dynamic, meaning that the sieve_extensions setting that was introduced for the new Sieve plugin properly affects the ManageSieve daemon as well. + Added support for the CHECKSCRIPT command. In terms of the supported commands, the ManageSieve daemon now complies with protocol VERSION 1.0 as listed in the CAPABILITY response. - Fixed maximum permissions for uploaded scripts; was 0777. This was shielded however by the default umask (not documented to be configurable), so the actual permissions would never have been 0777. - Fixed a segfault bug in the authentication time-out. Bug report and trace provided by Wolfgang Friebel. - Fixed handling of ~/ in use of mail-data for script location. - Fixed small problems in the login proxy support. The following files are released: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.3.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.3.tar.gz.sig ManageSieve package: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.3.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.3.tar.gz.s… ManageSieve patch: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.beta1-managesieve-0.11.3.di… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.beta1-managesieve-0.11.3.di… Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] delivering to folder based on recipient_delimiter?
by dovecot＠corwyn.net 13 Feb '09

13 Feb '09

I'm currently running postfix + dovecot, with virtual users In postfix I have set recipient_delimiter = + so that postfix accepts mail for user(a)example.com, user+foo(a)example.com, and user+spam(a)example.com all deliver to inbox. what I would like is to have email directed to user+foo(a)example.com delivered to the IMAP folder foo (and, in the context of amavisd, have amavis configured for recipient_delimited, and add addr_extension_spam_maps add +spam to each mail identified as spam, and thus the mail would go to the spam folder on delivery. The postfix guys say I should be able to do this. can someone point me to how to implement this with dovecot? (as I don't see how to even start). Thx Rick Rick Steeves http://www.sinister.net "The journey is the destination"

[Dovecot] Can't remove folder (no thunderbird issue)
by Jan Niggemann 12 Feb '09

12 Feb '09

Hi, first of all: yes, I already dug the internet but didn't find a solution - that's why I'm asking you. My provider uses dovecot, although I can't tell you more about the version - sorry. Mail is stored in mbox format. My trouble: I was unable to create subfolders and googled a bit. A proposed solution was to append a slash at the end of the folder name. I used Thunderbird to create a folder and called it "test/" (yes, with a slash). Now, in both, Thunderbird and Mulberry, I'm unable to delete that folder (that contains neither messages nor subfolders). Mulberry doesn't give an error message, and in Thunderbird I can't find an option to remove this folder (no matter if subscribed or not). My provider uses roundcube as a webmail interface. Trying to delete the folder there seems to work OK, but after refreshing the folder-view it re-appears. I have no (ssh|telnet|...) access to the server, so I can't remove the folder using the shell.. Do I have other options than calling support? Thank you already jan

[Dovecot] sendmail smtp auth using client socket
by EQX 12 Feb '09

12 Feb '09

Hi list I searched the net, but could not find something related. Is it possible to export the client socket to sendmail for smtp auth? What would be the sendmail.mc configuration for this? #client { # The client socket is generally safe to export to everyone. Typical use # is to export it to your SMTP server so it can do SMTP AUTH lookups # using it. #path = /var/spool/postfix/private/auth #mode = 0660 #user = postfix #group = postfix #} It can also be the other way round: can Dovecot use Cyrus SASL for user authentication? I need to use sendmail, ip based solutions like pop-before-smtp or poprelay are not an option. Thanks, Mike

[Dovecot] Mapping usernames
by Henry 12 Feb '09

12 Feb '09

Greets, We're using Dovecot 1.0.7 (which comes with CentOS 5.x). I have successfully configured dovecot to change a username from abc(a)123.com to realname1_abc for a machine which only has a single domain (using auth_username_format=realname1_%Ln). However, I'm pulling my hair out trying to get dovecot to handle multiple domains (the machine has existing /etc/passwd /etc/shadow and /etc/mail/virtusertable users). On an older machine, I simply hacked the source code to perform a berkeley DB lookup in /etc/mail/virtusertable.db for the realname[a-z0-9]_xx. This time round, though, I'm trying to do this cleanly. I've been reading the docs/wiki/etc but I now can't see the forest for the trees. This is what I've got so far: In /etc/dovecot.conf: ... auth default { userdb passwd-file { args = /etc/dovecot.passwd } passdb passwd-file { args = /etc/shadow #args = /etc/dovecot.passwd } } /etc/dovecot.passwd contains: realnamea_abc:{PLAIN-MD5}$1$Vjkfhaa....::::::userdb_user=abc@123.com I've been fiddling around blindly with all kinds of settings in userdb {} above, but I always get the error: "passwd-file(abc@123.com,::ffff:127.0.0.1): unknown user", amongst others. In a nutshell, I want to allow a user to login with abc(a)123.com, this name must be mapped to a real system user (eg, using /etc/dovecot.passwd), then authenticated against /etc/shadow or the MD5 password in /etc/dovecot.passwd I would appreciate any kind of pointers or advise here. It would have been nice if vpopmail allowed me to call an external perl script where I could perform the username mapping, but alas, this is not possible.

[Dovecot] (Somewhat urgent) Problem with maildir++ quota
by Santiago Romero 12 Feb '09

12 Feb '09

Hi. I have an strange problem with dovecot's maildir quota and postfix. I've tested quota and it works fine but sometimes there are users that having their Maildir/ empty, they trigger the "quota exceeded" message when someone sends email to them. Some config / version info: ### Versions: ii dovecot-common 1:1.0.10-1ubuntu5.1 ii dovecot-imapd 1:1.0.10-1ubuntu5.1 ii dovecot-pop3d 1:1.0.10-1ubuntu5.1 ### From dovecot.conf: (...) # SQL database <doc/wiki/AuthDatabase.SQL.txt> userdb sql { # Path for SQL configuration file args = /etc/dovecot/dovecot-mysql.conf } (...) dict { #quota = mysql:/etc/dovecot-dict-quota.conf } (...) plugin { quota = maildir:storage=51200 } ### dovecot-mysql.conf (splitted to be readable): user_query = SELECT maildir, 5000 AS uid, 5000 AS gid, concat('maildir:storage=', floor(quota/1024)) AS quota FROM mailbox WHERE username = '%u' AND active = '1' ### Database "mailbox" record example: | prueba(a)domain.com | Password | prueba | domain.com/prueba/ | 51200000 | domain.com | 2009-02-02 10:01:24 | 2009-02-02 10:07:46 | 1 | The symptons: users are working nicely, and quota works (If I create a new user and set it a quota of, say, 1MB, I can send him msgs until Maildir reachs 1MB, after that I get "quota exceeded" messages). But sometimes there are users with the Maildir empty that can't receive messages and trigger the "quota exceeded" warning. Users always download messages by POP. Removing "maildirsize" file in their folder fixes the problem. Also fixes it changing the quota to any value (maildirsize is then removed and recreated after a new message arrives for the user). Sometime that I don't know if it's strange is that I don't see "removing" messages in the maildirsize file after user downloads messages. I mean that I can't see "-1" lines in maildirsizes: # cat prueba/maildirsize 51200000S 0 0 615 1 1540 1 11446 1 46085 1 2623 1 21218 1 2815301 1 15110 1 21289 1 18330 1 (and so). Any idea of what's going on? Shouldn't appear "MSGSIZE -1" lines in maildirsize file to "restore" space in Maildir after POP RETRs? Currently I'm fixing the problem with a regular: # find /home/vmail/vhosts -name "maildirsize" -exec rm {} \; But there must exist a better solution (or maybe my config is wrong). Thanks a lot for any help. -- Santiago Romero

[Dovecot] Panic in dovecot 1.2.beta1
by Mark Sapiro 11 Feb '09

11 Feb '09

I tried Dovecot 1.2.beta1 yesterday. I had been using 1.1.11. I started getting "Panic: POP3(xxx): Trying to allocate 0 bytes" There are two kinds of pop3 users. In the attached log.txt file, user u1 is using a pop3 MUA. For users u2, u3, u4 and u5 fetchmail is coming through an ssh tunnel and retrieving their mail. u1 is able to interact normally with dovecot, but the fetchmail users encountered the panics in the log. dovecot -n is attached as dovecot-n.txt. At first I thought it was a locking issue as .lock files were being left behind, so I changed pop3_lock_session to no, and restarted dovecot, but this didn't help so I reverted to 2.1.11. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

I have: dovecot.conf mail_location: maildir:~/Maildir/ and /etc/dovecot/dovecot-ldap.conf with: user_attrs = sAMAccountName=mail=maildir:/home/vmail/%Ud/%Ln/Maildir/ So all the mail gets stored at /home/vmail/%Ud/%Ln/Maildir/ so if i add a new volume to the VM lets say /dev/disk3 and mount it to /srv/ vmail and then change the user_attrs = sAMAccountName=mail=maildir:/ home/vmail/%Ud/%Ln/Maildir/ to user_attrs = sAMAccountName=mail=maildir:/srv/vmail/%Ud/%Ln/Maildir/ would it work with no problem..? I would also need to move all the mailboxes already in the old location... I just want to make sure before i do anything.. Thanks

[Dovecot] Understanding dovecot ACLs
by Achim Hut 11 Feb '09

11 Feb '09

Hello List I am running a Cyrus IMAP that needs to be replaced. Geting a Dovecot IMAP up and running was surprisingly simple. My configuration is close to Johnny Chaddas Howto at http://johnny.chadda.se/2007/04/15/mail-server-howto-postfix-and-dovecot-wi… Its a Dovecot 1.1.10 on FreeBSD 6.4 Anyway, while basic setup was easy, i stuck in a couple of details like quota, managesieve, etc. Actual major problem and showstoper is understanding the ACLs the confuses me. So i need a hint to be guided in the right direction. What i need is a scenario, where user1 can get (for example) full access to the folders of user2, read-only access to user3 etc. A real world example: Secretary has full access to the mailfolders of her boss, boss has read-only acces to the sales-department folder. My questions: 1) is the possible? 2) can it be done with dovecot-acl files? 3) Namespaces: is it enough to have the private namespace for the job or do i need another namespace? 4) if yes, how should this namespace look like? Thanks for the help Achim

[Dovecot] dovecot logs to audit.log not to maillog
by Ralf Heidenreich 11 Feb '09

11 Feb '09

Hello, I have a curious phenomenon. Dovecot logs normally to /var/log/maillog. If I restart my server, dovecot loggs to /var/log/audit/audit.log. If I restart dovecot, dovecot loggs to /var/log/maillog again. And I think, wenn logrotate is restarting, dovecot logs to audit.log. But I don't know why. Any Ideas? greetings Ralf

[Dovecot] mailing lists and Dovecot deliver (lda)
by Roderick A. Anderson 11 Feb '09

11 Feb '09

I'm trying to figure out a way, or if it is even possible, to use mailing list software (majordomo2) on a Postfix + Dovecot + virtual mailboxes system. And where I should be looking. The examples on the Postfix site don't seem to address a purely virtual mailboxes system and I haven't found anything about doing it with deliver. I think I'm at the wrong tree (Dovecot deliver) and should be pestering the Postfix list. FTR, I host some sites for not-for-profits and they have asked about setting up lists. So far I've dodged the question but would like to attempt it now. Thanks, Rod --

[Dovecot] I've moved to US
by Timo Sirainen 10 Feb '09

10 Feb '09

I thought about saying this in v1.2.beta1 release annoouncement, but looks like it'll take a few more days. So I've moved to Blacksburg, Virginia and I'm now working for Mailtrust the rest of this year. Here's some talk about it: http://mailtrust.com/blog (A bit stupid looking picture, but then again all my pictures seem to be that way so I didn't bother getting a new one taken.) And if it's not clear from that blog: Pretty much everything I do here will be Dovecot improvements that will be released as open source. Mailtrust has actually been paying for Dovecot features for about 3 years now.

[Dovecot] redelivered mail results in mail-forwarding-loop
by Reto Glauser 10 Feb '09

10 Feb '09

I try to redeliver mail for the following reason: Once in a while a user receives a mail which isn't correctly recognised as SPAM/HAM. He'll move the mail into a specific folder (say: retrain-as-spam/retrain-as-ham) and a script will retrain the mail. What I'd like to do is to redeliver the mail in order for correct (re)delivery (e.g. sieve scripts). Using sendmail to redeliver the mail I'm able to re-run the spam tests which will add it's SPAM headers and dovecot/sieve will be able to correctly file the message. I tried to just resend the mail: # /usr/sbin/sendmail -f foo@bar -v -oi foo@bar < mail but this results in a Diagnostic-Code: X-Postfix; delivery via dovecot: mail forwarding loop for foo@bar The problem is that the mail already has a "Delivered-To: foo@bar" line. The above is working when the "Delivered-To" line is being removed, and my question is if this can't be done automatically?

[Dovecot] [Fwd: Re: dovecot logs to audit.log not to maillog]
by Ralf Heidenreich 10 Feb '09

10 Feb '09

Hello, now I have done this: under http://wiki.dovecot.org/Logging?highlight=(logging) Rotating Logs is the following string ----------------------- /bin/kill -USR1 `cat /var/run/dovecot/master.pid 2>/dev/null` 2> /dev/null || true ------------------------ This string I have insert in /etc/logrotate.d/syslog under the lines: postrotate /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true /bin/kill -HUP `cat /var/run/rsyslogd.pid 2> /dev/null` 2> /dev/null || true So Dovecot will be restarted, after the log rotates. I hope, the phenomenon is now solved. greetings ralf -------- Original-Nachricht -------- Betreff: Re: [Dovecot] dovecot logs to audit.log not to maillog Datum: Tue, 10 Feb 2009 09:07:26 +0100 Von: Ralf Heidenreich <ralf(a)lx-work.de> An: Timo Sirainen <tss(a)iki.fi>, dovecot(a)dovecot.org Referenzen: <499035E7.8090506(a)lx-work.de> <1234228183.6132.134.camel@timo-desktop> Hello, here is my dovecot.conf ------snip---------- log_path = /var/log/maillog info_log_path = /var/log/maillog -------snip------------- Is it possible, than logrotate rotates the maillog, and dovecot wants to write to it, if the maillog is not available at the moment, dovecot writes to audit.log?
