[Dovecot] deliver looking into root directory for sieve configuration ?
by Guillaume Hilt 03 Jan '09

03 Jan '09

Hi, I'm using dovecot (+sieve), dspam, clamav and postfix with wirtual users and domains. When the server receive an email, I get this error : Jan 2 14:48:52 mail postfix/qmgr[13573]: 89DE1276C42B: from=<postmaster(a)shadowprojects.org>, size=926, nrcpt=1 (queue active) Jan 2 14:48:52 mail deliver(postmaster(a)adomain.fr): chdir(/root) failed: Permission denied Jan 2 14:48:52 mail deliver(postmaster(a)adomain.fr): stat(/root/.dovecot.sieve) failed: Permission denied Jan 2 14:48:52 mail deliver(postmaster(a)adomain.fr): msgid=<495E1B33.5020009(a)shadowprojects.org>: saved mail to INBOX Jan 2 14:48:52 mail postfix/lmtp[13584]: 89DE1276C42B: to=<postmaster(a)adomain.fr>, relay=mail.mydomain.com[/var/run/dspam/dspam.sock], delay=0.07, delays=0.05/0/0/0.01, dsn=2.6.0, status=sent (250 2.6.0 <postmaster@adomain> Message accepted for delivery) Why does it look inside the /root folder for sieve configuration ? All virtual mailboxes are in /home/vmail/DOMAIN/USER/.maildir (owned by postfix:postfix; dspam has been put in the postfix group) I uploaded the following config files in http://hiltg.pastebin.com/ : - main.cf - master.cf - dovecot.conf - dspam.conf (mails are supposed to be delivered to the mailbox by dovecot, which is called by dspam) Any idea please ? Thanks and happy new year to you all, -- Guillaume Hilt

[Dovecot] Per-namespace proxying?

Hello, Searching in the archives, I saw the following posting from Timo Sirainen: [Dovecot] Roadmap to future (06 Dec 2007): [...] > Proxying > -------- > > - These could be implemented to v1.2. - Log in normally (no proxying) > if destination IP is the server itself. > > - Support for per-namespace proxying: > > namespace public { > prefix = Public/ > location = proxy:public.example.org > } > > There are two choices for this: Dummy IMAP proxying or handling it with > a mail storage backend. Dummy IMAP proxying would just let the remote server > whose mailbox is currently selected handle most of the commands and their > replies. I'm just afraid that this will become problematic in future. > ... (continues) Was this feature ever implemented? Is it in the 1.2 alphas? On a related note, were virtual mailboxes implemented? Thanks, Van

[Dovecot] Unkillable imap process?
by Johan Persson 03 Jan '09

03 Jan '09

Hi, Not sure if this is relevant but having been running dovecot 1.1.4 for a long time (without any problem) I recently upgraded to 1.1.7 when I switched to SuSE 11.1 This is just running on my home server and it's a fairly standard fetchmail-procmail-dovecot setup. However I recently had an incident which I cannot quite explain. I suspect it could be a possible disk problem but I did run a SMART check and the disks and HW seems ok. The mail store is mounted on a separate partition using ext3 fs What happened was that I noticed that the load on my server went through the roof and that the imap process was hogging 100% of the CPU and it had been running so for over an hour. Before this happened I had just setup a new laptop with Thunderbird as the mail client and had just done a off-line sync of my whole mail store (~1.5GB). So for a short time the dovecot server would have been under maximum load. I tried to recover by gracefully shutting down dovecot and when that didn't stop the imap process I first tried to be nice by sending it the TERM signal and when that didn't do it, the KILL signal. However, I was not able to stop the imap process. I then decided to recycle the server and initiated a shutdown. However, not even that was able to complete (since the shutdown process seemed to be hanging on not being able to stop the imap process). In the end I was (for the first time in over 6 years) forced to use the hard reset button on the server. I do realize that this is almost impossible to diagnose, but does anyone now in general what could possible cause the imap process to so completely be locked up that it is impossible to even shut it down? The dovecot -n output is 1.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27.7-9-pae i686 openSUSE 11.1 (i586) ext3 log_path: /var/log/dovecot.err info_log_path: /var/log/dovecot.info login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 2 login_max_processes_count: 2 login_max_connections: 5 max_mail_processes: 32 mail_max_userip_connections: 8 mail_location: maildir:/srv/mail/%u mailbox_idle_check_interval: 15 fsync_disable: yes auth default: passdb: driver: pam userdb: driver: passwd Cheers Johan

[Dovecot] NFS, IDLE, and index locking
by Jack Stewart 31 Dec '08

31 Dec '08

Hi, I'll try to keep short. My primary question is what, in people's experience, are the best configuration settings for to avoid potential NFS cache locking issues in an interesting heterogeneous environment? We appear to have a workaround for some locking issues we have seen, which is turning off IDLE. Upgrading our version of dovecot from 1.1.4 is likely to address some core issues, but I want to get the system setup in tune first. There are some things in our setup that seem dumb, and I would like to make sure they are dumb. As far as our environment goes, it isn't unusual for our users to connect with multiple different clients from multiple locations. Some of these clients behave well, and some not so well. In addition we have multiple distributed servers with multiple instances. Generally the connection from one of their clients/desktops goes to the same server but their different desktops may connect to different servers. If anyone has a similar enough environment, do you find it better to have the hard link setting off or is it better for you to turn it on? The attribute cache is the default (60 seconds) which works well enough in a polling setting but may be a problem with IDLE (30 second check). Do you find it better to bump up the IDLE check interval or drop the attribute cache? Our cache and maildir are on separate NFS volumes so we can change one without changing the other. Our tcp timeout setting is too long (it is the default). Do you find 180-300 seconds more reasonable? ---Jack To give some context, we have a handful of users with intermittent caching locking where the dovecot.index.cache file would simply not update. One of our internal people managed to get this problem when he was using pine (non-IDLE) with gnubiff (IDLE) from the same desktop. We haven't had any alarms since taking the brute force approach of turning off IDLE. Unfortunately other projects are inhibiting my capacity for additional debugging at this time. Also, it isn't clear to me that we will learn anything useful since the servers do not appear to be tuned and they are only running dovecot 1.1.4. Just for reference, below is our dovecot configutation. disable_plaintext_auth = yes base_dir = /var/run/dovecot/imap-server-its/ protocols = imap imaps syslog_facility = local4 shutdown_clients = yes ssl_cert_file = xxx.pem ssl_key_file = yyy.key ssl_ca_file = zzz.pem mail_location = maildir:/var/spool/maildir/%1Ln/%Ln:INDEX=/var/spool/dovecot/indexes/%1Ln/%Ln login_greeting_capability = no verbose_proctitle = yes mail_debug = yes imap_capability = "IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1" # MAILDIR Performance settings maildir_copy_with_hardlinks = yes maildir_copy_preserve_filename = no # Handling web logins & imap traffic login_processes_count = 16 login_max_processes_count = 2048 max_mail_processes = 4096 mail_max_userip_connections = 2000 # NFS settings mmap_disable = yes fsync_disable = no mail_nfs_index = yes mail_nfs_storage = yes dotlock_use_excl = yes lock_method =fcntl protocol imap { listen = *:10143 ssl_listen = *:10993 imap_client_workarounds = delay-newmail outlook-idle netscape-eoh } ## Authentication processes namespace private { separator = . prefix = Mail. inbox = yes } auth_verbose = yes auth default { mechanisms = plain login passdb ldap { args = /etc/dovecot.conf-ldap } userdb static { args = uid=vmail gid=mail home=/var/spool/maildir/%1Ln/%Ln } socket listen { master { path = /var/run/dovecot/imap-server-its/auth-master user = vmail group = mail } user = root }

[Dovecot] Bug in Dovecot 1.0.5 - CRYPT-MD5 not working
by Jim Salter 31 Dec '08

31 Dec '08

Problem: Using MySQL storage for the user and password db with MD5-CRYPT hashes, Dovecot fails to successfully authenticate when the MD5-CRYPT or MD5 settings are specified as default_pass_scheme in dovecot-mysql.conf. Dovecot /does/ successfully authenticate against MD5-CRYPT hashes when default_pass_scheme is set to CRYPT, which according to the docs should be DES encryption. (I do not know whether or not CRYPT actually works with DES hashes.) I am positive that I am using MD5-CRYPT hashes, as I have dropped in hashes from a Qmail/Vpopmail vpasswd file and they work with the CRYPT setting in Dovecot, as do hashes generated using htpasswd -nmb. Test system: Ubuntu Server 7.10, amd64 Dovecot 1.0.5 (from Ubuntu repositories) Postfix 2.4.5 (from Ubuntu repositories) Demonstration: # cat /etc/dovecot/dovecot-mysql.conf driver = mysql connect = dbname=redacted user=redacted host=127.0.0.1 password=redacted default_pass_scheme = MD5-CRYPT password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT maildir, 105 AS uid, 114 AS gid FROM mailbox WHERE username = '%u' # htpasswd -nmb user password user:$apr1$bZQl//..$2IPoOibTBaqpG7pPFigOy/ # mysql -u postfix -p mysql> use redacted; Database changed mysql> update userdb set password='$apr1$bZQl//..$2IPoOibTBaqpG7pPFigOy/' where username='user'; Query OK, 1 rows affected (0.00 sec) mysql>quit Bye # telnet localhost 143 Trying 127.0.0.1...

[Dovecot] SSL cert problems.

I'm really racking my brain trying to figure this one out here. I am running a pop3 server for remote offices on CentOS 5.2.

[Dovecot] Password field limitations

Hi, I've searched the WIKI for this information but seem unable to find anything about it. What limitations are imposed on the password for IMAP/POP3 users?

I use PLAIN authentication, passwords are stored in a MySQL database. Thanks a lot -- Tom Sommer

[Dovecot] automounting home dirs
by Roger Hale 29 Dec '08

29 Dec '08

Hi, I'm running dovecot-1.0.10 on a Solaris 10 server with home dirs automounted over NFS. I have set the mail_location configuration option so that nothing should be written to a user's home dir over NFS but, as far as I can tell, dovecot still by default tries to chdir to a user's home dir when reading mail, although this is not required. This creates additional unnecessary load on a heavily-loaded fileserver and generally slows everything down and creates an unnecessary dependency. Is there a way to prevent dovecot from causing the home dirs to be mounted? I found this thread: http://markmail.org/message/umywuppl3vvzfe4p#query:dovecot%20mount%20home%2… which discusses the same problem, but it's quite old and there doesn't seem to be a definitive answer other than hacking the passwd file or the code. Is there a more elegant solution? TIA. _________________________________________________________________ Get a bird’s eye view of the world with Multimap http://clk.atdmt.com/GBL/go/115454059/direct/01/

[Dovecot] Logging logs moved/deleted

Hi dovecot list, I'm looking for a possibility to log a moved (or a deleted mail). For example, I have a mailbox, and I read it in IMAP. I have a mail in INBOX. I want to move it to Folder. I want to have this action logged in my dovecot log file (or an other file). Is it possible? I read this: http://wiki.dovecot.org/Logging and I don't find any informations about it. I try to set "mail_debug=yes", but it does not log what I want. Thanks. Best regards (and happy Xmas). -- -Nicolas.

Meaning that no user information, other than the obvious email address associated with an specific email so that each email can be showed to the right user, will be stored in a MySQL database instead of /home/vmail/DOMAIN/<user> Would I get any advantages.? Would it be better, faster? Thanks

[Dovecot] Is there a straight forward way to associate login with imap process

23 Dec '08

Hi, Is there a way to associate a user's the login (imap-login) process with the user's 'imap [' process? We are trying to lock down an issue to make sure we full understand it. /proc and shared memory tools weren't particular useful. Just for context, we are having an intermittent locking index cache locking issue that appears to impact only a subset of our users. The index files are on NFS. It may be fixed by a dovecot patch (we are at 1.1.3), adjusting our tcp_timeout on the servers, upgrading out circa 2000 load balancer, the type and configuration of the multiple simultaneous persistent clients that user is using, etc. lslk, alert logs, strace, testing the most recent 1.1.X version, and file mtime is giving us some information but we want to make everything is covered. Many thanks in advance. ---Jack -- Jack Stewart California Institute of Technology jstewart(a)caltech.edu / www.imss.caltech.edu

[Dovecot] POP3 Immediate Connection Termination
by Kat Wisnosky 23 Dec '08

23 Dec '08

Hey everyone... Thanks in advance for any help. I seem to have the opposite problem that a lot of people have - I've been running Dovecot v. 1.0.10 quite successfully for IMAP for several months.

[Dovecot] Move mail in Maildir without IMAP
by RW 21 Dec '08

21 Dec '08

I set-up some spam/ham learning folders where a crontab entry learns the mail and them moves it do a different Maildir folder. Unfortunately, since it has a different dovecot-keywords file, any imap flags get changed to unknown-0, unknown-1 etc. I tried the following, but it didn't work mv "${src_ham}"/cur/* "$dest_ham"/new/ cp "${src_ham}"/dovecot-keywords "${dest_ham}" Is there a simple way to do this correctly without going through IMAP? And are there any more serious consequences of moving mail like this, with dovecot imap running on top.

20 Dec '08

Hello, I intend to set up a mail server for a few domains with Dovecot/Postfix/MySQL/DSPAM and antispam plugin. The better solution to manage users would be to set up a ldap server. So, do anyone have ever set up this kind of server with dovecot ? Any advice that would help me ? Thanks, -- Guillaume Hilt

[Dovecot] More info from mail_log plugin
by Bardur Haskor 19 Dec '08

19 Dec '08

HiWe need to track exactly when our users read messages. Unfortunately, I haven't been able to figure out how we can achieve this with Dovecot. Then I saw the mail_log plugin.Is it possible to extend the plugin to also log system flag changes? This would be great, because then we could see in the log files when the Seen flag has been set. Changes in user defined flags would also be interesting to track.I know this would create a lot of log entries, but for us this wouldn't be a problem. Maybe the plugin would default to not tracking flag changes, but could be configured to do so.RegardsBardur Ha Skor _________________________________________________________________ Connect to the next generation of MSN Messenger http://imagine-msn.com/messenger/launch80/default.aspx?locale=en-us&source=…

[Dovecot] "nopassword" extra field useless with LDAP passdb
by Zohan 19 Dec '08

19 Dec '08

Hi, We are trying to implement a highly secure mail server with user authentication restricted to SSL certificates only (not using passwords at all). Still, user information is stored in a LDAP directory. In this configuration LDAP is used to check whether the user is registered (and probably supply quota and other info), and actual authentication is done by SSL layer. According to wiki, a "nopassword" extra field should be supplied, together with empty password. But there is no way to return an empty password from LDAP, as LDAP simply does not allow "empty attributes"; if an attribute is present, it is not empty. Supplying empty password as a static field (like this: pass_attrs = uid=user,=password=,nopassword) works an odd way, allowing empty password only, not "any password", and most MUAs (including our target Thunderbird) do not allow empty passwords. Log excerpt follows ("1" was entered as a password during POP3 session; static empty password was configured as above): ==================== Dec 9 02:11:15 localhost dovecot: auth(default): ldap(user1,127.0.0.1): pass search: base=ou=People,dc=example,dc=com scope=subtree filter=(&(objectClass=inetOrgPerson)(uid=user1)) fields=uid,nopassword Dec 9 02:11:15 localhost dovecot: auth(default): ldap(user1,127.0.0.1): result: uid(user)=user1 Dec 9 02:11:15 localhost dovecot: auth(default): ldap(user1,127.0.0.1): Password mismatch Dec 9 02:11:15 localhost dovecot: auth(default): ldap(user1,127.0.0.1): PLAIN(1) != '' Dec 9 02:11:17 localhost dovecot: auth(default): client out: FAIL 1 user=user1 Dec 9 02:11:19 localhost dovecot: pop3-login: Aborted login (auth failed, 1 attempts): user=<user1>, method=PLAIN, rip=127 .0.0.1, lip=127.0.0.1, secured ==================== That's why we now have to maintain a separate passwd-like file with the following contents: user1:::::::nopassword user2:::::::nopassword ... and so on (updating it each time manually as users are added/removed), and use it as passdb. Only this allows true "any password" policy. In fact, the problem seems to be a little bit deeper. In our setup user/password challenge is not needed at all. This is exactly what RFC 4959, "IMAP Extension for Simple Authentication and Security Layer (SASL) Initial Client Response", is about (http://tools.ietf.org/html/rfc4959 , see SASL EXTERNAL example). Are there any plans to implement SASL EXTERNAL mechanism in Dovecot? Thank you! Zohan

[Dovecot] OT: Looking for a robust IMAP client
by Stewart Dean 19 Dec '08

19 Dec '08

This weekend we had a runaway email endless loop. When it was killed after 18 hours, my inbox had 135,000 messages in it...there were two messages that were being endlessly sent and bounced and I'm on the postmaster alias. Thunderbird was able to do a mass select of one of the two messages, and deleted 65,000, but after that it locked up. I ended up firing up Pine to do the final 65,000...whereas TBird had had mulitple imap sessions (and failed), Pine only had one and did the job. And even after I had done the mass delete of the other 65,000 and the inbox was down to 2000 messages, TBird was still hiding under the covers and telling me there were still 135,000 messages. In the end, I had to kill the TBird profile for that account and recreate it. Is there a simple robust IMAP client to replace Pine (which I *think* is no longer supported)? GUI or TTY session? I'm wondering if there is something we can tell users to use when Things Are Dire. GUI would be better since it removes one of the few remaining reasons for a logon server -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] [PATCH] drop root privileges on solaris, request for testing
by Andrey Panin 18 Dec '08

18 Dec '08

Hello all, this patch allows master process to drop more root priveleges under Solaris. My limited testing shows that code works, but I'm not sure that defined privilege set is permissive enough for dovecot. Unfortunately I have no root access to our Solaris servers to really test it. So if someone is ready to test this patch please do it :) Best regards.

[Dovecot] Dovecot imap processes pinning CPU
by David Rosenstrauch 18 Dec '08

18 Dec '08

In recent days, dovecot's "imap" processes keep getting stuck. Each time I check my server (running dovecot 1.1.7) there's a bunch of "imap" processes (sometimes 2 of them, sometimes 4, sometimes 6) that are using all of the box's CPU. And worse, there's no way to kill the processes either (neither kill -15 or kill -9 works), which means that I wind up having to reboot the box every time this happens. REALLY irritating. I don't normally even *see* the imap processes in htop, as I think they're pretty short lived. And I'm not sure what they're looping trying to do. My debugging skills on Linux are a bit weak, and so I don't know how to look at the process and see what it's doing. Also, not sure what's changed on my system to cause this, as this is definitely a recent problem. Maybe the upgrade to Thunderbird 2.0.0.18 (since I usually use T'Bird to access my email). I don't seem to run into this problem when I use Squirrelmail. Anyone have any idea what the problem might be? Or, if not, then suggestions on how I might be able to debug the situation myself? TIA, DR

[Dovecot] SSL Certificate Authentication
by Anthony Davies 18 Dec '08

18 Dec '08

Hi Guys, I am using the SSL Client Certificate authentication method for my Dovecot instance, however rather then just requiring the client certificate it also prompts me for my user password. My certificate was securely generated on a smart card and is passphrase protected so I would like to stop having to enter my certificate passphrase and my user password to collect my mail. Where abouts in the config file can I resolve this issue? Cheers, Tony Davies

[Dovecot] v1.1.6 released

17 Dec '08

http://dovecot.org/releases/1.1/dovecot-1.1.6.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.6.tar.gz.sig The invalid message address parsing bug is pretty important since it allows a remote user to send broken mail headers and prevent the recipient from accessing the mailbox afterwards, because the process will always just crash trying to parse the header. This is assuming that the IMAP client uses FETCH ENVELOPE command, not all do. Note that it doesn't affect versions older than v1.1.4. + dovecot -n and -a now prints some system information at the top. + More error/debug message logging improvements. - pop3-login: Fixed assert-crash if a client sent USER+PASS+USER+PASS commands in the same IP packet. - Parsing an invalid message address like "From: (" caused an assert-crash in v1.1.4 and v1.1.5. - Folding whitespace wasn't handled correctly inside quoted-strings, causing some messages to be parsed incorrectly. - mbox: Fixed saving messages that begin with a valid From_-line.

I was planning on using these to redesign LDAP configuration (e.g. home=/var/mail/%{ldap:homeDirectory}) - imap/pop3 proxy: Support master user logins. - Improved some error messages

[Dovecot] Syncing several emails accounts with offlineimap and dovecot
by Joe Bloggs 17 Dec '08

17 Dec '08

Hi, I have just installed dovecot and offlineimap on my laptop for syncing with my gmail, and reading in gnus, as outlined in this article: http://sachachua.com/wp/2008/05/08/geek-how-to-use-offlineimap-and-the-dove… I am using Debian Etch, and I am the only user. The only change I made to the default dovecot.conf file was to set: mail_location = maildir:~/MailDir I read that gnus doesn't handle Maildir very well, so I need to connect directly to dovecot, and this is what I have specified in my offlinemap conf file: [Repository Local] type = IMAP remotehost = localhost port = 143 remoteuser = me remotepass = secret I want to sync my other online email accounts aswell. Can anyone tell me how to do this? Thanks.

Hello, i have following problems using dovecot-antispam plugin (Dovecot >1.1.3, FreeBSD 8.0-Current, dovecot-antispam 1.0/1.1) dovecot-antispam compiled using dspam-exec/mailtrain, with/wo debugging (i've tried all possibilities) When i try to move message to SPAM folder (using dspam-exec backend) i'm getting IMAP error: antispam signature not found and in dovecot logs: Nov 23 23:44:24 freebsd dovecot: IMAP(mr): Next message unexpectedly lost from 2708619 Using mail backend gives this error too(only IMAP error changes: failed to read mail beggining). Commenting out following code in mbox_read_from_line function (in src/lib-storage/index/mbox/istream-raw-mbox.c) helped and plugin was working correctly, but only with Dovecot <=1.1.3. if (stream->istream.v_offset - rstream->hdr_offset + new_pos > rstream->mail_size) { /* istream_raw_mbox_set_next_offset() used invalid cached next_offset? */ i_error("Next message unexpectedly lost from %"PRIuUOFF_T, rstream->hdr_offset + rstream->mail_size); rstream->eof = TRUE; rstream->corrupted = TRUE; rstream->istream.istream.stream_errno = EINVAL; stream->pos = 0; return -1; } Now, with versions >1.1.3 this won't helps and plugin fails. Anyone knows how to get it working? I would like to upgrade to newest dovecot release Best regards, mr

Hello, I use the debian packages from http://xi.rename-it.nl/debian/ version 1.1.7-0~auto+17 If I put a sieve script into /home/vmail/sieve-scripts/test.de/test.sieve it is used, so cmusieve works.

[Dovecot] Replace Domainname in Mail Location
by Manuel Schmidt 15 Dec '08

15 Dec '08

Hello, I dont fully understand how the domain name replacement in mail_location takes place. If I connect to the server using my username as in the text file i can not access my Maildirs as %d gets not replaced. If i user username(a)domain.com the %d is correctly replaced. But, how would i configure my mail_location, to take the domain part from the server name i connect to? So i could set up my client to connect to mydomain.com and have just my username set as login? I did not find a variable that seems to be more correct than %d. So i guess i have to configure that elsewehre? In userdb?

[Dovecot] Horde IMP w/ dovecot folder list
by LÉVAI Dániel 15 Dec '08

15 Dec '08

Hi! I'm using dovecot-1.1.7, Horde-3.3.2 and IMP-4.3.2. The left-side folder list has some folders, whos names contains localized (non-ascii) characters. This is displayed correctly when I select the "English (American)" language entry on the login page from the dropdown menu. But when I choose my locale, which is "Magyar" (Hungarian), the folders won't display the correct characters. It's like this: With "English (American)" locale: Ügyfél With "Magyar" locale: &ANw-gyf&AOk-l The latter is the same displaying as with the folder's name on the filesystem: # ls -1 user/Maildir/ [...] .&ANw-gyf&AOk-l/ [...] I've sent this message to imp@ but, they say it is a problem with my mailserver, which I suspected, because the wrong folder names are exactly the same as the folder names on the filesystem. Is there any way to solve this? Thanks in advance, Daniel -- LEVAI Daniel PGP key ID = 0x4AC0A4B1 Key fingerprint = D037 03B9 C12D D338 4412 2D83 1373 917A 4AC0 A4B1

[Dovecot] 1.1.7: quota problem, unable to delete mails when quota exceeded
by Arkadiusz Miskiewicz 15 Dec '08

15 Dec '08

Hi, When user exceeds it's quota then dovecot can't create it's files and it's showing zero mails :( This also means that user is unable to delete it's own mails. Sounds like kind-of bug, right? Dec 15 08:28:37 mbox1 dovecot: IMAP(xxx): open(/var/mail/xxx/dovecot-uidlist.lock) failed: Disk quota exceeded Dec 15 08:28:37 mbox1 dovecot: IMAP(kdudus): file_dotlock_create(/var/mail/xxx/dovecot-uidlist) failed: Disk quota exceeded This sometimes ends with: Dec 15 08:36:43 mbox1 dovecot: IMAP(xxx): Disconnected: Internal error occurred.

[Dovecot] Performance issue about maildir path.
by Zhang Huangbin 15 Dec '08

15 Dec '08

Hi, all. Normally, i use 'domain.ltd/username/Maildir' as users' maildir path, if i change them to hash style, e.g. 'A0/B0/domain.ltd/C0/D0/username/Maildir', will it speed up the index operation for MDA? If we have 10000 users, which maildir path style will improve performance? Thanks very much. :) -- Best regards.

Has anyone used Toltec to connect Outlook to Dovecot hosted message stores? Primary advantage over Bynari is price - $14 per client. I have used it with Kolab and been very happy.

[Dovecot] confused about deliver
by Neal Becker 14 Dec '08

14 Dec '08

I have dovecot serving a maildir in ~/Mail.imap. In Mail.imap I have cur/ new/ tmp/ .maillist1/ .maillist1/cur .maillist1/new .maillist1/tmp ... I made a sieve script, which looks like: require "fileinto"; if header :is "Subject" "test" { fileinto "test"; } ... with no final else clase. When mail is delivered to a maillist, caught by my sieve script, it goes into the correct subdir of maildir. But, when not caught by the script, I get: Dec 14 11:53:27 localhost deliver(nbecker): msgid=<d9f848520812140850q190f104fva5f586e43fa03994(a)mail.gmail.com>: saved mail to INBOX I can't find this mail saved to INBOX. There are no modified directories under maildir that I can find. Where did this mail go? I wanted it to go into the toplevel cur/, which is where my client finds them.

[Dovecot] SIEVE resources ?
by Xavier Maillard 14 Dec '08

14 Dec '08

Hi, Do you any good SIEVE resources for a poor beginnner ? I'd to translate some of my current procmail rules into SIEVE. I have, for example, a "generic" rule that is able to sort almost any message from/to a mailing-list into a dedicated folder -i.e one rule for almost all my lists. Any recomendation ? Thank you

[Dovecot] Mailbox name
by Xavier Maillard 14 Dec '08

14 Dec '08

Hi, I am using SIEVE to filter/sort my incoming mails. I am subscribed to tens of mailing lists and I would like to file messages into folder of this pattern: INBOX/list/<tld>/<domain name>/<list name> So for example help-gnu-emacs(a)gnu.org would be filed under: INBOX/list/org/gnu/help-gnu-emacs The problem is Dovecot is telling me that this mailbox name is invalid. What can I do ? Cheers

[Dovecot] Imap logging and inetd
by Jonathan Siegle 14 Dec '08

14 Dec '08

When I ran /usr/local/sbin/dovecot, the variable login_log_format_elements from dovecot.conf was honored. Now when I run /usr/local/libexec/dovecot/imap-login from /etc/inetd.conf, it isn't. How do I get imap-login to write log lines that use login_log_format_elements for the format? This is dovecot-1.2.alpha3 soon to be alpha4. Thanks, Jonathan

[Dovecot] Panic in 1.1.6 file ioloop.c: line 206
by Laurent Blume 14 Dec '08

14 Dec '08

Hi all, I just had a panic with dovecot 1.1.6, two days after replacing 1.0.15 with it in production. Here are the logs immediately preceding the panic, I think they're related. It seems the user connected simultaneously from two different clients, from his own computer and a webmail running on the server, then manipulated mail folders on one side, and logged out. The panic occurred 3 seconds after the logout. Is there a setting I might have missed that could avoid that?

[Dovecot] proxy and master user
by Matthieu Herrb 14 Dec '08

14 Dec '08

Hi For some application we need a master user on our IMAP servers. We use dovecot 1.1.7 in proxy mode, with proxy_maybe (some mailboxes are on the proxy itself, others are on remote servers, also running dovecot). But the proxy removes the '*master' suffix from the username when using the master user to log in on the proxy. So the base name of the user with the master password are submitted to the real server, which of course fails. Is there a way to tell the proxy to forward the master user to the real server, without forcing it in destuser, since we also need to have regular (non master) logins? Thanks in advance. -- Matthieu Herrb

[Dovecot] Broken sorting(?)
by Michael M. Slusarz 14 Dec '08

14 Dec '08

Somewhere between revision f5554ae61732 (12 days ago) and the release of 1.2a4 (f53952ac4285; 9 days ago) sorting appears to have broken. With the older revision, I see the following (using Maildir): a sort (ARRIVAL) US-ASCII ALL * SORT 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 2 1 With the newest code, I see this: a sort (ARRIVAL) US-ASCII ALL * SORT 124 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 2 1 Obviously, that duplicate sequence number (124) is not a good thing (shouldn't the sequence numbers be in order for an arrival search anyway?). Deleting any message in the mailbox always makes the last sequence number appear at the beginning. I can verify that another IMAP server on the same machine views the mailbox just fine: a sort (arrival) US-ASCII ALL * SORT 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 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 michael

[Dovecot] Possible bug in Maildir++ quota?
by Ulrich Zehl 13 Dec '08

13 Dec '08

While researching a possible bug in our custom-made Maildir++ expiration script, I found the following in src/plugins/quota/quota-maildir.c. | static const char * | maildir_list_next(struct maildir_list_context *ctx, time_t *mtime_r) | { | [...] | *mtime_r = st.st_size; | return str_c(ctx->path); | } As far as I unterstand, this seems incorrect, because the value in mtime_r is used, for example, in maildirs_check_have_changed to check whether any maildirs or folders have changed. If this isn't a bug, please satisfy my own curiosity and tell me what I'm missing. Ulrich

[Dovecot] imap quota makes the Alarm clock expire
by Magnus Appelquist 12 Dec '08

12 Dec '08

Hello list, I have a strange problem with dovecot and quota. The error message is not obvious... After a couple of seconds when I try to start dovceot, I get this: root@taleira:~# /etc/init.d/dovecot start Alarm clock If I uncomment the "imap_quota and quota" in dovecot.conf everything seem to work fine: protocol imap { listen = *:143 ssl_listen = *:993 # problem pa taleira01: konstigt... #mail_plugins = quota imap_quota mail_plugins = } I can't really figure out what's wrong. There's nothing in the log and dovecots error message is not so talkative. It took a while to figure out that it was the quota that caused the problem.

[Dovecot] freebsd 7, panics - kqueue?
by mike-maillist＠nux.co.uk 12 Dec '08

12 Dec '08

Hi, We have a issue with a server pretty much just running dovecot, there's about 250gb of maildirs which has about 200 simultaneous connections to it running on freebsd 7. The machine has stayed up for about 8 days before it panics but sometimes panics after about 24 hours. We are running a PAE kernel (with ULE scheduler) as the machine has 2 (4 core processors) and 8gb of ram, dovecot is compiled with kqueue support which i suspect is causing the panics. We are currently trying with a GENERIC kernel to see if this addresses the issue but looking back through the dovecot lists there seems to be some issue with kqueue, freebsd and dovecot, i am tempted to simply disable kqueue in dovecot but am not sure on the performance penalties. Please see the freebsd pr for the kgdb dumps - for both dumps the current process was imap, and the second one seemed to hint towards a problem with kqueue but im not a c or kernel hacker: http://www.freebsd.org/cgi/query-pr.cgi?pr=129550 --- snip of what i think is relevent from the dump --- (kgdb) list *0xc04c4c4d 0xc04c4c4d is in knlist_remove_kq (/usr/src/sys/kern/kern_event.c:1615). 1610 if (!kqislocked) 1611 KASSERT((kn->kn_status & (KN_INFLUX|KN_DETACHED)) == KN_INFLUX, 1612 ("knlist_remove called w/o knote being KN_INFLUX or already removed")); 1613 if (!knlislocked) 1614 knl->kl_lock(knl->kl_lockarg); 1615 SLIST_REMOVE(&knl->kl_list, kn, knote, kn_selnext); 1616 kn->kn_knlist = NULL; 1617 if (!knlislocked) 1618 knl->kl_unlock(knl->kl_lockarg); 1619 if (!kqislocked) (kgdb) mail# dovecot -n # 1.1.7: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.0-RELEASE-p6 i386 ssl_cert_file: /etc/ssl/dovecot.pem ssl_key_file: /etc/ssl/dovecot.pem login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_process_per_connection: no login_processes_count: 20 login_max_processes_count: 256 login_max_connections: 512 max_mail_processes: 1024 verbose_proctitle: yes first_valid_uid: 89 last_valid_uid: 89 first_valid_gid: 89 last_valid_gid: 89 mail_privileged_group: mail imap_client_workarounds: delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep auth default: passdb: driver: vpopmail userdb: driver: vpopmail

[Dovecot] Dovecot authentication not supported in Entourage
by jan gestre 12 Dec '08

12 Dec '08

Hi Guys, I recently configured an mail server running postfix + dovecot + mysql + postfixadmin, everything is running ok except for Mac Entourage clients which is a PITA IMO, I always get a authentication not supported error while thunderbird and outlook on windows don't. Any ideas or workaround? my dovecot version is dovecot-1.0.7-2.el5. here's the output of dovecot.conf and dovecot-sql.conf respectively: # dovecot -n # 1.0.7: /etc/dovecot.conf base_dir: /var/run/dovecot/ log_timestamp: %Y-%m-%d %H:%M:%S ssl_cert_file: /etc/postfix/ssl/mail-cert.pem ssl_key_file: /etc/postfix/ssl/mail-key.pem login_dir: /var/run/dovecot//login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login first_valid_uid: 150 last_valid_uid: 150 mail_access_groups: mail mail_location: maildir:/home/virtualmail/%d/%u mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 user: nobody passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot-sql.conf socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 user: postfix group: mail master: path: /var/run/dovecot/auth-master mode: 432 user: virtualmail group: mail # cat /etc/dovecot-sql.conf [root@mail ~]# cat /etc/dovecot-sql.conf driver = mysql connect = host=localhost dbname=postfix user=dovecot password=dovecot69 default_pass_scheme = MD5 user_query = SELECT '/home/virtualmail/%d/%n' as home, 'maildir:/home/virtualmail/%d/%n' as mail, 150 AS uid, 12 AS gid, concat('dirsize:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1' # Get the password password_query = SELECT username as user, password, '/home/virtualmail/%d/%n' as userdb_home, 'maildir:/home/virtualmail/%d/%n' as userdb_mail, 150 as userdb_uid, 12 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' TIA.

[Dovecot] Duplicate suppression from remote lists?
by Adam Seering 12 Dec '08

12 Dec '08

Hi, I have a setup where users on my server who are subscribed to several lists on a (remote) weirdly-configured listserver are getting many duplicate e-mails. I know why this is happening; but I don't have control over that listserver so I can't fix it. Is there a way for me to suppress duplicates from within Dovecot? The duplicates do all have the same (otherwise-unique) message ID. "dovecot --version" gives 1.0.rc15. I'm using exim for SMTP. I'm also using dovecot-lda, with the Sieve plugin. There's a rather old thread on this list that mentions that dovecot-lda+Sieve should be able to suppress duplicates; it's not doing so automagically, though... Thanks, Adam

[Dovecot] W= fixup feature
by Arkadiusz Miskiewicz 12 Dec '08

12 Dec '08

Hi, When there are maildir mail files without W= tag in name then dovecot opens them, read data inside to calculate W= size, cache that information etc. Would be it sensible to have option where dovecot would fix names of such files? Like if no W= then after calculating size rename file to actually contain W= ? -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

Does an option like "pop3_no_flag_updates = yes" also exist for imap? Is it maybe planned? Or should I just provide a patch? Adrian

Hi, is there a *simple* HOWTO that explains a simple postfix+dovecot setup? Up to now, I used postfix+cyrus, worked fine. But I do not get postfix+dovecot to work.

[Dovecot] removal of all keyword.
by Matthias Rieber 11 Dec '08

11 Dec '08

Hi, how can I remove all keywords from an existing Maildir/? After reading the docs I assume this might work: 1. Stopping dovecot 2. Removing all lowercase [a-z] from the filename flags 3. Removing the dovecot-keywords file 4. Removing the dovecot.index / dovecot.index.* files Is that correct? matthias

[Dovecot] Mixing MBOX and MAILDIR
by Romer Ventura 09 Dec '08

09 Dec '08

Hello, I have about 100 mboxes, a few with a lot of mails and others with a few mails. I have configured dovecot to use maildir as mail format, but I would like to give users the ability to access their old email located in their old mbox. So all the new mail would be in the ~/Maildir/ and their old or archived email in /home/vmail/mboxmail/%Ln How can I add a namespace to achieve my goal...? namespace private { separator = / hidden = yes prefix = "#mbox/" location = mbox:/home/vmail/mboxmail/%Ln/ } Like that...? Thanks for any inputs...

[Dovecot] LDA questions
by Romer Ventura 08 Dec '08

08 Dec '08

Hello, I am looking at the docs and I see this: Problems with deliver Namespaces are supported with v1.1 and later. With v1.0 and older versions mails can be delivered only to mailboxes specified by the mail_location setting. But in the dovecot.conf I see: # NOTE: Namespaces currently work ONLY with IMAP! POP3 and LDA currently ignore # namespaces completely, they use only the mail_location setting. I am running 1.1.7 so is that a typo in the dovecot.conf or the wiki page..? Also, I got postfix+dovecot configure to authenticate to Active Directory using pam_krb5 and I am able to login and send emails with pop3 or imap, but unable to receive emails since postfix complaints about the user not being found in the local recipient table. Now I have made a few changes, but I cant get to see deliver complaint, all I see is: postfix/smtpd[19924]: NOQUEUE: reject: RCPT from ............: 550 5.1.1 <test1(a)domain.com>: Recipient address rejected: User unknown in local recipient table; So I think that it is not being passed to deliver... Master.cf has: dovecot unix - n n - - pipe flags=DR user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} Main.cf has: virtual_mailbox_domains = your.domain.here virtual_transport = dovecot Any ideas..?

[Dovecot] Just some user input
by Brandon Lamb 08 Dec '08

08 Dec '08

Hi Timo, You may remember some of my mails, I was having unusual high load issues using pop3 with dovecot over nfs, and unusual being the load on anywhere from 1 to 4 servers would run at 2 to 4 for a week then all of a sudden would spike to 60 and higher (saw 150 once). I have been banging my head on the wall for the last 1.5 to 2 months since switching from courier to dovecot, the imap has worked great but the pop3 was a problem out the door. Anyway, I finally tried loading dovecot directly on our raid, all loads across the board dropped to the floor. The single P4 3ghz purrs along at an easy 0.30 load where the 1 to 4 quad core boxes with brand new hardware were loading up to 60 when using nfs. So, my experience has been that maildir, nfs and dovecot as the pop3 server was unusable. I wasnt really sure this whole time, it seemed odd that a single P4 box using nfs and courier pop3 could handle the entire system load but dovecot with the same and more quad cores fell over was weird. Anyway, this is totally not meant as a bashing or anything, just information. Im not a C programmer so I really cant offer anything but my input/observations. Maybe the pop3 part of dovecot isnt really given much love or people are mostly just interested in the imap server? Or maybe most people dont use nfs? Totally just assumptions here. A definite positive here though, after moving dovecot directly to the raid server, wow, our mail TOTALLY hauls ass now. Two of our managers both noticed the huge speed increase. One of them uses pop3 and leave messages on server and has almost 4,000 messages in the inbox on the server, his webmail now loads literally instantly, i click login and count 1 second. That is amazingly fast. I dont have any hard numbers, but before our upgrades his "feeling" was that he seems to remember it taking up to 30 seconds for webmail to load his mailbox. that is an incredible difference. Our webmail uses imap by the way, so this is probably a combination of moving from nfs and switching from courier to dovecot. Ok thanks for your great hard work and sorry for the novel size post.

[Dovecot] catching authentication failures with LDAP backend
by Udo Rader 06 Dec '08

06 Dec '08

Hi, we have recently been hit by a couple of brute force password attacks against dovecot. So what I want to do now is to add dovecot to fail2ban in order to block further attacks. However, I don't seem to be able to find out password verifification failures for our LDAP based user data. The only thing I see are loads of lines like these in the logfiles: -------CUT------- dovecot: Nov 30 09:09:51 Info: pop3-login: Disconnected: user=<ludovic>, method=PLAIN, rip=217.147.235.52, lip=81.16.98.99 dovecot: Nov 30 09:09:51 Info: pop3-login: Disconnected: user=<luna>, method=PLAIN, rip=217.147.235.52, lip=81.16.98.99 dovecot: Nov 30 09:09:51 Info: pop3-login: Disconnected: user=<luke>, method=PLAIN, rip=217.147.235.52, lip=81.16.98.99 -------CUT------- Googling the web I found that PAM based authentication obviously gives a matchable error message, but for some reasons the ldap backend does not - or does it? Any pointers highly appreciated :-) dovecot -n says this: -------CUT------- # 1.0.15: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log protocols: imaps imap pop3 listen: 81.16.98.99 ssl_listen(default): 81.16.98.99 ssl_listen(imap): 81.16.98.99 ssl_listen(pop3): ssl_cert_file: /etc/bestsolution/ssl/mail.bestsolution.at-cert.pem ssl_key_file: /etc/bestsolution/ssl/mail.bestsolution.at-key.pem ssl_parameters_regenerate: 24 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: 9 mail_access_groups: mail mail_privileged_group: mail default_mail_env: mbox:~/mail/:INBOX=/var/mail/%u mail_location: mbox:~/mail/:INBOX=/var/mail/%u mmap_disable: yes lock_method: dotlock maildir_copy_with_hardlinks: 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): %v.%u auth default: mechanisms: plain digest-md5 cram-md5 login passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix -------CUT------- -- Udo Rader, CTO http://www.bestsolution.at

I have an unsigned SSL certificate with Dovecot and connect fine using OSX.5's Mail.app. What do you mean, "unable to connect"? Do you really mean "unable to connect", or do you mean, "an error message comes up every time they try to connect"? If its the latter complaint, please see this document: http://support.apple.com/kb/TA22383 I know it says 10.3 Mail, but the steps to follow are essentially unchanged between 10.3 and 10.5.

Hi, People using the new OS X mail client are unable to connect to the unsigned dovecot-mkcert.sh certificate on my Dovecot installations. Turning off SSL fixes the problem. Is there any way to make it work automatically, or do I just have to get the certificates signed? Has anyone figured this one out before? Thanks, Chris

[Dovecot] quota warning for fs quota
by Florian Effenberger 05 Dec '08

05 Dec '08

Hello, I configured my Dovecot to use filesystem (fs) quota. It works fine, the correct free/used space and percentage is being shown to the client. However, the warning feature doesn't seem to work, no mail is being sent, although executing the script standalone works fine. Is quota warning for fs quota supported? I use Dovecot 1.0.10 (Ubuntu package). Thanks, Florian

Hello, I have postfix+dovecot authenticating via LDAP to Active directory and everything is working fine except that some user names get changed by dovecot. # cat dovecot/dovecot-ldap.conf hosts = 192.168.50.30 192.168.50.31 base = ou=HST-Users,dc=h-st,dc=com ldap_version = 3 auth_bind = yes dn = cn=<account>,cn=Users,dc=h-st,dc=com dnpass = <password> user_attrs = sAMAccountName=mail=maildir:/home/vmail/%Ud/%Ln,=gid=1000,=uid=1001 user_filter = (&(objectClass=person)(mail=%u)) pass_filter = (&(objectClass=person)(mail=%u)) I am using the value of ³mail² field from active directory as user name.

[Dovecot] Auth_username_format question
by Romer Ventura 05 Dec '08

05 Dec '08

Hello again, I have change authentication to LDAP from Kerberos due to recent changes to my plans and I am having a little problem getting the malbox created in desired path. At the moment the home folders are being created in: /home/vmail/DOMAIN.COM/%Ln and it worked great with kerberos, but with LDAP the domain part is missing so I did the following: Auth_username_format = %Ln Then I did: # telnet localhost pop3 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user test4(a)domain.com +OK pass password +OK Logged in. But I saw in the logs the following: dovecot: auth(default): master out: USER 1 test4 uid=1001 gid=1000 home=/home/vmail//test4 The domain was missing.. So does it mean that auth_username_format dictates what dovecot will use, not only for the authentication part, but for everything else as well..? To me it seems that once the username has been formatted it forgets everything that doesn¹t constitute part of the specified format. Or am I misunderstanding the entire concept..? How cant I preserve the domain part so that the homes can be placed in the desired location: /home/vmail/%d/%u...? Thanks

[Dovecot] Dovecot Proxy with MySQL auth
by Justin Krejci 05 Dec '08

05 Dec '08

We are looking at deploying several pop/imap servers to house the mail for 15,000 or more mailbox accounts. We are contemplating on the design and are looking at using MySQL auth (we already have a MySQL environment in place for our user auth to live) and proxy_maybe so each server can proxy for all the others and we just have a network load balancer distribute the incoming connections to all of the Dovecot servers. Each server would have its own local maildir storage for the users local to that server and all of the authentication and target backend pop/imap server data would be stored in the same MySQL database. The problem we are running into is the documentation is not very clear on this type of scenario. http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy At the bottom of this page it gives a query example of "SELECT NULL AS password, ." but that does not seem to allow for us to use the proxy_maybe if the destination server is localhost (and therefore do not proxy) it does not seem that the above query will actually send the real password for authentication. Is this a misunderstanding on our part or is the use of mysql auth + proxy_maybe not feasible? Assuming the latter we surmised using a separate instance of Dovecot on each machine to act solely as a proxy front end (use proxy instead of proxy_maybe) then on the second instance there is no proxy config and it listens on a separate TCP port like 80143 or whatever. Any input or suggestions would be appreciated. Justin Krejci

I've been running 1.2alpha3 for weeks now without issue. However, some people in my testing department object to even testing "alpha" code. Are there specific features/bugs that need resolved before alpha reaches beta? Thanks, Jonathan

[Dovecot] Dovecot authenticating to multiple kerberos realms
by Romer Ventura 04 Dec '08

04 Dec '08

Hello, I got Postfix, Dovecot 1.1.7 configure to use pam and the pam.d/dovecot file is configure to use pam_krb5 module. Everything is working with no problems, but I am finding that the user must type the domain part in uppercase in order to successfully authenticate. So I am wondering if there is any way for the user to login as user1(a)domain.com instead of user1@DOMAIN.COM...? Any ideas..? Thanks

[Dovecot] Antispam plugin + scriptsieve
by Allan Cassaro 03 Dec '08

03 Dec '08

Hi, I wrote a little python program that works with antispam plugin, to create or remove sieve rules based on "From:" of any e-mail that is moved to some folder configured in dovecot.conf. He works fine with "Felamimail" the email program of "eGroupware". After setup, is very simple: If an user move a message to "blocked" folder, is appended a rule in the script sieve of this user. If the message is deleted or moved out that folder, the rule is removed too. The setup is very simple: (after setup antispam plugin) Change this in dovecot.conf: protocol imap { mail_plugins = antispam } plugin { antispam_spam = Blocked antispam_mail_sendmail = /usr/libexec/dovecot/blockthis.py antispam_mail_sendmail_args = -u;%u antispam_mail_spam = -a antispam_mail_notspam = -d } Hooo... this script create a "include global script" statament in script sieve... If you don't want this feature, just comment this 2 lines: sievelist.append('require ["fileinto", "include"];\n') sievelist.append('include :global "global.sieve";\n') Here this is very useful! :D This script was created to suit my needs, so, have some paths in the code... It's not very "user friendly" yet... but if have intereting I will implement others features (like a config file). Download here: http://allan.cassaro.googlepages.com/blockthis.py Regards.

[Dovecot] my_vsnprintf crash on HP-UX
by Marc Beyer 03 Dec '08

03 Dec '08

Hi, sorry for the double post, I stupidly composed this as a reply to an earlier mail, which causes it to appear in an older thread. Posting again so it doesn't get lost in the archives: dovecot 1.1.7 reliably crashes every time I try to open a mailbox using IMAP. Error in the logs: dovecot: Dec 02 23:14:15 Error: setmntent(/etc/mtab) failed: No such file or directory dovecot: Dec 02 23:14:16 Panic: IMAP(arandomuser(a)example.com): my_vsnprintf(): Output string too big dovecot: Dec 02 23:14:16 Error: child 4815 (imap) killed with signal 6 dovecot: Dec 02 23:14:19 Panic: IMAP(arandomuser(a)example.com): my_vsnprintf(): Output string too big dovecot: Dec 02 23:14:19 Error: child 4816 (imap) killed with signal 6 ...
