-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello all, I've been running dovecot authenticating against a local MySQL database, but it has come time to implement it with a remote database. Instead of using stunnel, I'd rather take advantage of MySQL's native SSL support. I didn't know if this was possible with dovecot, and if it was, what config changes I might need to get it going. I found the below page/patch from some time ago and tried to use the ssl_key and ssl_cert directives in /etc/dovecot-sql.conf, but it didn't seem to recognize them (perhaps I need to compile mysql-ssl support into dovecot manually?): http://www.dovecot.org/list/dovecot-cvs/2004-July/003003.html Also, I noticed a need for ssl_ca and ssl_ca_path but am unfamiliar with how to generate what's needed if these options are required. FYI, dovecot 1.0.7 is running on CentOS 4.5, using rpm from ATrpms: http://dl.atrpms.net/el4-i386/atrpms/stable/dovecot-1.0.7-0_63.el4.i386.rpm Thanks for any advice or documentation pointers you can provide.

[Dovecot] deliver to subfolder?
by Ralf Hildebrandt 06 Nov '07

06 Nov '07

Can dovecot's deliver deliver a mail to a certain subfolder within a user's mailbox? I was thinking of something along the lines of: deliver -m subfolder But what is the correct syntax to deliver to "spam", subfolder of INBOX? deliver -m spam < message.txt deliver -m INBOX.spam < message.txt -- Ralf Hildebrandt (Ralf.Hildebrandt(a)charite.de) plonk(a)charite.de Postfix - Einrichtung, Betrieb und Wartung Tel. +49 (0)30-450 570-155 http://www.arschkrebs.de

[Dovecot] truncated messages / attachments
by Markus Stumpf 05 Nov '07

05 Nov '07

I am currently running dovecot-1.1.beta6 (at least beta5 also had the problem) Retrieving some messages via IMAP gets them truncated and it also happens with retrieving attachments (message is HTML part of multipart-alternative, attachments are at least some PDF files). A user reported she is rather sure one of the messages was ok, before moving it to some other folder. In the filesystem the messages are there in full length. It happens with Outlook as well as with Thunderbird. We're using Maildir. After upgrading from beta5 to beta6 I have removed all dovecot.index* files of a folder with a defect message. This didn't make a difference. (Thought it could be related to some indexing problem). Any one else seeing this? \Maex -- Markus Stumpf

[Dovecot] Couldn't init INBOX: Can't sync mailbox: Messages keep getting expunged
by Tom Sommer 05 Nov '07

05 Nov '07

After updating Dovecot, one of my servers keep spamming these errors in the log: dovecot: Nov 03 14:14:18 Error: POP3(foo(a)bar.com): Getting size of message UID=4402 failed dovecot: Nov 03 14:14:18 Error: POP3(foo(a)bar.com): Getting size of message UID=4402 failed dovecot: Nov 03 14:14:18 Error: POP3(foo(a)bar.com): Couldn't init INBOX: Can't sync mailbox: Messages keep getting expunged The funny thing is the mailbox is empty, there are no mails in the folder that should be needed to be parsed It was perfectly fine before I updated, and the permissions on the folder is correct. It only affects some mailboxes as well. Any ideas? // Tom

I guess the reason is that ZFS can now make use if it's caching capabilities. Delivers activity is completely random since it's impossible to load balance a connection based on the e-mail recipient, since only the ip is known at the load balancing point. Therefore I have fsync_disable=no for deliver. It's easy to force the clients using imap/pop3 to the same server since it can be based on the ip only. Therefore I have fsync_disable=yes for imap/pop3. This changed everything. Now there's a real performance gain upgrading from 1.0.x to 1.1.x. About two or three times less disk activity overall (reads were already improved) for both reads and writes. Thats pretty neat!

[Dovecot] Dovecot write activity (mostly 1.1.x)
by mikkel＠euro123.dk 04 Nov '07

04 Nov '07

Im experiencing write activity thats somewhat different from my previous qmail/courier-imap/Maildir setup. This more outspoken in v.1.1.x than v1.0.x (Im using Maildir). Write activity is about half that of read activity when measuring throughput. But when measuring operations its about 5-7 times as high (measured with zpool iostat on ZFS). I think this might be due to the many small updates to index and cache files. Anyway since writing is much more demanding to the disk than reads dovecots ends up being slower (only a little though) than my old qmail/courier-imap/Maildir was. And the old setup didnt even benefit from indexes like Dovecot does. (What I mean saying slower is that it can service fewer users before it hits the wall). Of course theres also lots of benefits using Dovecot. Im just wondering whether this was a thing that should be focused on for later versions (maybe writes could be grouped together or something like that). Dovecot is very cheap on the CPU side so the only real limit in terms of scalability is the storage. Regards, Mikkel

[Dovecot] Sieve error messages (sieve 1.1.2, dovecot 1.1b6)
by mikkel＠euro123.dk 04 Nov '07

04 Nov '07

Sorry for spamming the list today:) Im getting a lot of these errors in the deliver log: deliver([recipient]): [date] Info: sieve runtime error: Fileinto: Generic Error deliver([recipient]): [date]:18 Error: sieve_execute_bytecode([path-to-sieve]) failed deliver([recipient]): [date] Info: msgid=<[msgid] >: save failed to [foldername]: Quota exceeded In this case the account is over the defined Dovecot quota limit. Dovecot knows what to do but sieve seems to throw its standard error message. Is there something wrong with Sieve or is it just that the error is misleading? This has been present in all v1.1.x I think (some changes was made to the error messages in b3 or b4 but believe this didnt change). Regards, Mikkel

[Dovecot] *notify config for 1.0.x doesn't enable inotify

hi, the current code has changed include linux/inotify.h to sys/inotify.h since 2006-01-17, but that won't work with inotify*.h as documented in the wiki. One has to either revert back to linux/inotify.h, or add #include <sys/inotify-syscalls.h> to both configure.in and src/lib/ioloop-notify-inotify.c Or, just symlink sys/inotify.h -> linux/inotify.h.

[Dovecot] IMAP vs system username logging with checkpassword auth
by dale gallagher 03 Nov '07

03 Nov '07

Hi After upgrading to dovecot 1.0.7 I noticed that the actual username is no longer logged, but rather the system user (in my case 'vmail') under which my virtual set-up runs. Now I'm unable to see which virtual users log in. Any pointers on how to configure dovecot to log the actual username given during the IMAP dialogue would be appreciated. My dovecot.conf includes the following: auth default { mechanisms = plain passdb checkpassword { args = /var/qmail/bin/qmail-vauth } userdb prefetch { } user = auth } An example logfile entry: 2007-11-03 15:41:56.027191500 dovecot: Info: imap-login: Login: user=<vmail>, method=PLAIN, rip=192.168.0.141, lip=192.168.0.10, TLS

[Dovecot] MANAGESIEVE patch v8 for dovecot 1.0.7
by Stephan Bosch 03 Nov '07

03 Nov '07

Hello dovecot users, I have updated the MANAGESIEVE patch to the latest stable version of dovecot (1.0.7). This new version also adds extra configuration settings to explicitly specify the location of the sieve storage and the active sieve script. Additionally, the README now more clearly explains the configuration of the daemon. It currently won't compile with 1.1 due to significant changes in the master code. However, because 1.1 now approaches a stable release, the next version is going to be updated to version 1.1. Change Log V8 ------------- + Fixed a few incompatibilities with 1.0.7 version. For instance, the "Logged in" message is now sent by the -login process and not by the managesieve daemon anymore. This caused a segfault every once in a while. + Probably fixed the settings problem reported by Steffen Kaiser regarding login_dir. 'dovecot -n' now reports correct results, but testing will show whether the whole problem is solved. + The managesieve daemon now accepts the sieve_storage and sieve configuration settings, so it is now possible to explicitly configure the location of the sieve storage and the active script respectively. The daemon still falls back to using the mail_location (MAIL) settings if nothing else is specified. + The cyrus timsieved does not use the + character in string literals and many clients have adopted to this behaviour. The latest managesieve (08) advises to accept a missing + from clients. The server should not send any + characters as well. This behavior is now implemented on the server. + Cleaned up sieve-storage.c: split up the sieve_storage_create function in various sub-functions for obtaining the various paths and directories. + Forced manual intervention if rescueing a non-symlink file at the active script path fails somehow. Previously, this presented the admin with a log message that it had just eaten the script, which is not very nice. + Restructured the README.managesieve file and added some more explanation with regard to the configuration of the daemon. This patch still includes (yet another) instance of the CMU Sieve source, as explained in one of my previous e-mails (http://dovecot.org/list/dovecot/2006-July/015016.html) The patch can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.7-MANAGESIEVE-v8.diff.gz The README.managesieve is located in the root of the dovecot source tree after applying the patch. Have fun testing the patch. Don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] Listening only on localhost

Hi! I've got dovecot 1.0.rc15. I want dovecot to listen only on localhost for imap, and on any interfaces for imaps. So I put the following into my config: protocol imap { listen = 127.0.0.1:143 ssl_listen = *:10993 .. } dovecot -n correctly reports: listen: 127.0.0.1:143 ssl_listen: *:10993 But I can still do a 'telnet MY_HOST 143' from the outside, and 'netstat -pltn | grep dovecot' reports: [ip changed ;)] tcp 0 0 77.my.ip.253:10993 0.0.0.0:* LISTEN 4847/dovecot tcp 0 0 77.my.ip.253:143 0.0.0.0:* LISTEN 4847/dovecot Am I doing something wrong?

[Dovecot] Bug within Authentication Caching
by Matthias Waffenschmidt 02 Nov '07

02 Nov '07

Hello, there seems to be a bug in the authentication caching code when using it in combination with username_translation (using the current version 1.0.7 on FreeBSD 6). I've set username_translation to +@:@ to allow usernames of the form test+dom.ain or test:dom.ain (historical reasons force us....). If someone has a successful login using the username test(a)dom.ain, the subsequent authentication information is read from the cache, no matter which of the 3 possible usernames the client uses the next time. But if someone has a successful login using the username test+dom.ain, the following data has or has not been found in the cache: test+dom.ain: miss test(a)dom.ain: miss test:dom.ain: hit If the first username is test:dom.ain the behaviour is the following: test:dom.ain: miss test(a)dom.ain: miss test+dom.ain: hit I've added the information if the username changes for better debugging possibilities. In practice the username is of course always the same. The complete authentication part of the tested config: auth default: cache_size: 10000 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@:+ username_translation: +@:@ verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /var/pop/%d/Accounts.passwd userdb: driver: static args: uid=70 gid=70 home=/var/emtpy It looks as if Dovecot does some wrong username translations before inserting/lookup up the data in the cache. BTW: a SIGUSR2 signal to the dovecot-auth process does not give any information as suggested in http://wiki.dovecot.org/Authentication/Caching. Please do not only answer to the list as I am not subscribed.

[Dovecot] dovecot + LDAP + SASL?
by hadmut＠danisch.de 02 Nov '07

02 Nov '07

Hi, I would like to setup an IMAP server with SASL and LDAP support. As far as I can see dovecot supports SASL and LDAP, but not the way I need it. If I understand dovecot correctly, it has it's own set of SASL mechnisms and uses the LDAP server just to store the plaintext password. In case of authentication dovecot fetches the plaintext password from LDAP and then performs the SASL steps internally. I need to support proprietary SASL mechanisms built into an LDAP server, which are not based on just a single password. So is there a way to configure dovecot to just pass SASL through to LDAP, allowing the IMAP client to talk SASL with the LDAP server through dovecot? regards Hadmut

[Dovecot] Successful experience with auth_winbind module
by Dmitry Butskoy 02 Nov '07

02 Nov '07

Hi, Recently the support of Samba's ntlm_auth helper was added to dovecot-auth (mech-winbind.c etc.). It is alrready in 1.1, the patch for 1.0 is here: http://dovecot.org/patches/1.0/dovecot-1.0.3-winbind.patch . It allows auth against NT or AD domain. I would like to infrom all that we successfully use this new feature during 2 month and ~300 users 24x7 (an energy power company). No any failures at all! This feature allows to specify "SPA" (Secure Password Authentication) option in OE, and to avoid explicit user passwords in mail accounts. Some random notes: - In the mixed environment (both plain and ntlm methods in use), you have to specify: mechanisms = plain ntlm login i.e. "ntlm" before "login". When sending mails, OE just catch first seen and try to use it, even if you specify to use SPA in the mail account preferences. - It seems that MS Outlook requires the specifying of password even when SPA is in effect - When OE has several identities, and one of the identities has SPA for SMTP set (outgoing mail), it wins over all another identities. - "The Bat" mailer supports NTLM for reading, not sending, and requires password too. Regards, Dmitry Bustkoy http://www.fedoraproject.org/wiki/DmitryButskoy P.S. We use NTLM only, GSS-SPNEGO still not tested.

Theirs is a proprietary system which from what I've read, seems to use SMS in combination with IMAP. Wacky. (If you aren't talking about iPhone compatibility, I'm less knowledgeable, but dovecot does support IDLE-style "imap push" style notification.) Alan Ferrency

[Dovecot] mail_location and master_user rel 1.0.x
by Robert Heller 02 Nov '07

02 Nov '07

login me(a)mymail.net*theboss thebossespwd this is a great piece of software, but it has some frustrating issues. i have included my two configurations below, just FYI. the one (older) system is 1.0rc7 on mandriva 2007.0 and postfix 2.3.3 and amavisd and spamassassin and using a maildir configuration the newer system is 1.0.5 (soon to be 7) on mandriva 2008.0 and postfix 2.4.5 amavisd and spamassassin and using a maildir configuration first, i followed the instructions in this document http://wiki.dovecot.org/Authentication/MasterUsers to the letter and it works for neither the old server nor the new. specifically i was using the first example configuration. all i ever got was: Connected to mail.mailserver.com Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS STARTTLS AUTH=LOGIN AUTH=PLAIN AUTH=DIGEST-MD5] Dovecot ready. login him(a)mailserver.com*theboss thebossespwd login BAD Error in IMAP command received by server. and the auth_debug information was completely useless. if someone goes to the trouble of writing great examples they really should test to make sure they actually work. secondly: this configuration on the old server (1.0rc7) works fine: ## Dovecot 1.0 configuration file base_dir = /var/lib/dovecot protocols = imap pop3 imaps log_path = /var/log/dovecot/error.log info_log_path = /var/log/dovecot/info.log first_valid_uid = 60000 last_valid_uid = 60000 first_valid_gid=15 last_valid_gid=15 default_mail_env = maildir:/var/spool/mail/%d/%u mailbox_check_interval = 60 maildir_copy_with_hardlinks = yes mbox_locks = fcntl umask = 0077 auth default { mechanisms = plain digest-md5 user = dovecot passdb pgsql { /etc/dovecot/dovecot-pgsql.conf } userdb pgsql { /etc/dovecot/dovecot-pgsql.conf } socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = postfix group = mail } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = mail } } } but the same configuration on the newer version 1.0.5 does not work, the problem being in mail location (note changed from default_mail_location to mail_location). so i had to make a number of changes... ##

[Dovecot] receive date wrong in outlook
by Farkas Levente 01 Nov '07

01 Nov '07

hi, we migrate from exchange to dovecot. we do it with imapsync. first we try to do it with --syncinternaldates, but this fails on many messages with invalid date, so we drop this option. unfortunately after this those users who use outlook see the received date as the date we do the migration in stead of the real received date. other clients eg webmail, thunderbird etc sees the right date. so my question what can i do? it's a dovecot bug or outlook and if outlook's bug is there any workaround fro this? thanks in advance. -- Levente "Si vis pacem para bellum!"

I wanted to know if it is possible to authenticate user for IMAP and POP3 access seperately using a database? All I have seen in the documentation/wiki is a single query for authentication.

[Dovecot] 1.1Beta5 Issue
by Jeff Grossman 30 Oct '07

30 Oct '07

I installed 1.1Beta 5 this weekend. I had no problems at all yesterday using Thunderbird. I started reading my mail with Squirrelmail this morning and everything was going pretty smooth. I tried to delete a daily e-mail I receive from careerbuilder.com and the IMAP process shot up to 99.9% and I was not able to do anything in Squirrelmail. I killed that process and tried it again just to be sure what it was. And it did it again. I can delete any other message with no problems, just that one causes me issues. I am not sure if Thunderbird is the same, I will have to wait until I get home tonight. If there is any troubleshooting you would like me to do, please let me know. Jeff

Hi all, Sorry if this is trivial. I am just concerned. In Poland we will be putting the clocks one hour behind (back) on Sunday. I once saw dovecot killing itself because I manually adjusted the clock in the past. Will it not happen in this case? Thanks for your ideas. Zbigniew Szalbot

[Dovecot] Static home while using LDAP
by David Bosque 29 Oct '07

29 Oct '07

Hello all, I've been googling for a workaround for this for nearly a week to no avail and I hope someone in the list can shed some light on it. I have downloaded and compiled dovecot 1.0.5 and applied the quota-warning to it. I have configured everything and it's working wonderfully, even the lda with the sieve plugin. This is my current relevant configuration: userdb static{ args = uid=501 gid=12 home=/var/mail/buzones/%d/%n allow_all_users=yes } passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } However, I need to obtain some more data from LDAP, so I need to switch to an ldap userdb, but want to keep the home as it is in the static configuration and not having to store it in LDAP. Is it possible to use a fixed home (as in the static userdb) while using an ldap userdb? I am looking for something similar to user_global_uid and user_global_gid but for the "home". If not, is it possible to fix or append something to the values in the user_attrs (like the following)? user_attrs = [whatever_i_want_to_append]uid=home uidNumber=uid,gidNumber=gid Regards, David Bosque

[Dovecot] v1.0.7 released

http://dovecot.org/releases/1.0/dovecot-1.0.7.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.7.tar.gz.sig Almost missed this one. I had already fixed it in v1.1 tree, but forgot to fix in v1.0 tree. - deliver: v1.0.6's "From " line ignoring could have written to a bad location in stack, possibly causing problems.

[Dovecot] lost emails with version 1.0.6
by Nishant Limbachia 29 Oct '07

29 Oct '07

Hi list members, I am using dovecot on Slackware 12.0 with postfix 2.4.5. I just upgraded to version 1.0.6 from 1.0.5 and now I am not getting emails. I am using dovecot deliver with postfix. deliver log also says email put into appropriate inbox. Starting up dovecot doesn't show any error messages. I've looked at the release notes and couldn't find any changes that should affect the config file. Here's an excerpt from dovecot deliver's log for the last two emails I've lost after upgrade. ### deliver(raghu): Oct 28 19:34:52 Info: msgid=<200710281935.AA6815928(a)stuart.iit.edu>: saved mail to INBOX deliver(raghu): Oct 28 19:40:13 Info: msgid=<200710281940.AA82444392(a)stuart.iit.edu>: saved mail to INBOX ### Any ideas? ---- tuxrules.in(a)gmail.com

[Dovecot] do 1.1b4 assertion failed: (mailbox_list_is_valid_existing_name
by Adam McDougall 28 Oct '07

28 Oct '07

I think this is where I left off last weekend. Instead of this happening at the base of one of my shared mail namespaces, it happens when I try to select a top level folder inside the namespace, or try to directly select an entire path to a folder. This only happens when ACL is enabled. Let me know if I need to provide more. Thanks.

Is it possible somehow to configure a fallback for a failed proxy? I am using sql based proxying through dovecot, but it would be nice if you can fallback to another host if the proxy destination server is down. High availability and all.. Regards, Cor

[Dovecot] More core dump stack traces
by Lloyd Parkes 28 Oct '07

28 Oct '07

Hi all, I found a whole bunch of core files from imap this evening, so here are the stack traces from each. Unlike my last message, I don't have debugging symbols for these, so there isn't any analysis I can easily do. There were several cores with the first stack trace and one with the second trace. The core dump for the second trace is the only one I noticed. I suspect that the first trace happens when the client host goes to sleep. If so, the situation needs to be handled more gracefully. I'm currently building a copy of imap with debugging symbols.

[Dovecot] Possible Caching Bug showing up as a MIME Boundary Issue
by Kevin A. McGrail 27 Oct '07

27 Oct '07

Possible Caching Bug showing up as a MIME Boundary Issue I'm using Dovecot version 1.0.0. I was using Dovecot version 1.0.0 beta3 or alpha4. I upgraded to Dovecot 1.0.0 to make sure that was not the issue. Over the past few weeks on a server running a stable dovecot, I have seem a few emails arriving where the MIME document structure dividers are visible. I've included a screenshot showing this. Using OE6 as client. Have tried adding oe6-fetch-no-newmail per clients wiki but this seems to stop the ability to login at all. I am using two different machines with Outlook Express to access the same email. The same problem will show up on both. Usually, if I delete the .imap cache for the folder, the email comes down correctly. My dovecot -n output is: # /etc/dovecot.conf listen: *:144 ssl_listen: *:994 ssl_cert_file: /usr/local/ssl/certs/stunnel.pem ssl_key_file: /usr/local/ssl/certs/stunnel.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login max_mail_processes: 50 verbose_proctitle: yes default_mail_env: mbox:~/:INBOX=/var/spool/mail/%u mail_location: mbox:~/:INBOX=/var/spool/mail/%u imap_client_workarounds: outlook-idle delay-newmail auth default: passdb: driver: pam userdb: driver: passwd userdb: driver: prefetch The server is on a heavily modified RedHat 7.2 on x86 box with ext3 Thanks in Advance, KAM

[Dovecot] trouble deleting folders that only contain folders
by Ken A 27 Oct '07

27 Oct '07

Hi, I'm using dovecot 1.0.5 with mbox storage. Users can't delete folders that are created to 'only hold other folders'. I can create these folders with no problem. They are directories in the file system. Normal folders (which are mbox files) are deleted with no problem. I've tried with both squirrelmail and Thunderbird, and what happens when a delete is requested, is that all files within the folder's dir tree are deleted and the client is unsubscribed, but the directory tree remains. Any ideas? Thanks, Ken -- Ken Anderson Pacific.Net
