[Dovecot] MySQL auth issues?
by Matthias Saou 03 Apr '06

03 Apr '06

Hi, Since my last email about RHEL4 problems on x86_64, I've kept trying to figure out what the problem might be, and just ran into a reply to an old email I sent to the list, which I had missed. It suggests that the issue might be in the MySQL authentication that I'm using. Here is a more detailed log entry, with auto debugging on : Apr 3 13:13:02 s1 dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=::ffff:195.x.x.x rip=::ffff:195.x.x.x resp=AHBhcnRuZXJzQdNvbW1lcm3lZ2F0ZS5jb20Aa2F2YWthdmE= Apr 3 13:13:02 s1 dovecot: auth(default): client out: OK 1 user=x(a)domain.com Apr 3 13:13:02 s1 dovecot: auth(default): master in: REQUEST 70 22190 1 Apr 3 13:13:02 s1 dovecot: auth-worker(default): sql(x@domain.com,::ffff:195.x.x.x): SELECT maildir, 101 AS uid, 103 AS gid FROM mailbox WHERE username = 'x(a)domain.com' Apr 3 13:13:02 s1 dovecot: auth(default): master out: USER 70 x(a)domain.com maildir=domain.com/x/ uid=101 gid=103 Apr 3 13:13:02 s1 dovecot: pop3-login: Login: user=<x(a)domain.com>, method=PLAIN, rip=::ffff:195.x.x.x, lip=::ffff:195.x.x.x Apr 3 13:13:02 s1 dovecot: pop3(x(a)domain.com): ^GUnexpected eof found when reading file 'UNOPENED' (Errcode: 0) Apr 3 13:13:02 s1 last message repeated 2 times Apr 3 13:13:02 s1 dovecot: pop3(x(a)domain.com): Disconnected: Logged out top=0/0, retr=0/0, del=0/2, size=17174 Those "Unexpected eof found when reading file 'fileName'" messages are apparently from MySQL, as one can see here for instance : http://www.mysqlfreaks.com/errors/49.php Here is my relevant configuration (all the rest is the default) : login_greeting = Ready. verbose_proctitle = yes first_valid_uid = 101 default_mail_env = maildir:/home/vmail/%d/%n:INDEX=MEMORY auth_cache_size = 512 auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain passdb sql { args = /etc/dovecot-mysql.conf } userdb sql { args = /etc/dovecot-mysql.conf } } The INDEX=MEMORY was added because of similar errors with the indexes : Apr 3 12:56:44 s1 dovecot: pop3-login: Login: user=<x(a)domain.com>, method=PLAIN, rip=::ffff:195.x.x.x, lip=::ffff:195.x.x.x, TLS Apr 3 12:56:44 s1 dovecot: pop3(x(a)domaine.com): Corrupted transaction log file /home/vmail/domain.com/x/dovecot.index.log: unexpected end of file while reading header Apr 3 12:56:44 s1 dovecot: pop3(x(a)domain.com): Corrupted transaction log file /home/vmail/domain.com/x/dovecot.index.log: unexpected end of file while reading header Apr 3 12:56:44 s1 dovecot: pop3(x(a)domain.com): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 (this was when the auth_debug wasn't enabled) Here is my /etc/dovecot-mysql.conf file : driver = mysql connect = host=/var/lib/mysql/mysql.sock dbname=postfix user=postfix password=xxx default_pass_scheme = PLAIN password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT maildir, 101 AS uid, 103 AS gid FROM mailbox WHERE username = '%u' I'm using MySQL 4.1.12-3.RHEL4.1 (the original RHEL4 packages), with the server on the same machine (hence the socket access). I was seeing this also with 0.9, not just 1.0 betas. With x86_64 packages, any slight change to the main dovecot.conf file can prevent dovecot from starting (segfault with "Unexpected eof found when reading file 'UNOPENED' (Errcode: 0)" message), whereas i386 packages work somewhat better. This is on the same machine with an i386 compatibility layer. Is anyone using MySQL auth successfully? Any help or pointers would be more than welcome.

[Dovecot] mbox-sync-update.c error
by Carlos Vicente 03 Apr '06

03 Apr '06

Hi, I think the problem is in Dovecot. I'm using both Evolution and Thunderbird on a Gentoo box. One of my folders keeps locking up and the clients can't retrieve the messages. The situation appears to be triggered by trying to move a message into that folder. Deleting the index files (under /var/log/dovecot/xxx/) solves the problem (temporarily). I get these error messages in the logs: Mar 31 15:10:34 dovecot: imap(cvicente): mbox sync: UID inserted in the middle of mailbox /home/xxx/Mail/xxx (93 > 3, seq=93, idx_msgs=3455) Mar 31 15:10:34 dovecot: imap(cvicente): file mbox-sync-update.c: line 55 (mbox_sync_move_buffer): assertion failed: (ctx->mail.offset + ctx->mail.space <= ctx->hdr_offset + pos || ctx->mail.offset > ctx->hdr_offset + pos + have) Mar 31 15:10:35 dovecot: child 32373 (imap) killed with signal 6 M I'm running dovecot-1.0_beta3 Hope this gets some attention from the developers. cv >In the maillog I get > > Mar 29 09:17:25 bree dovecot: imap-login: Login: user=<hartr>, > method=plain, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured > Mar 29 09:17:25 bree dovecot: imap(hartr): mbox sync: UID inserted > in the middle of mailbox /var/mail/hartr (8 > 1, seq=2, idx_msgs=4) > Mar 29 09:17:25 bree dovecot: imap(hartr): file mbox-sync-update.c: > line 55 (mbox_sync_move_buffer): assertion failed: (ctx->mail.offset > + ctx->mail.space <= ctx->hdr_offset + pos || ctx->mail.offset > > ctx->hdr_offset + pos + have) > Mar 29 09:17:26 bree dove

[Dovecot] imap processes remaing after dovecot shutdown
by Marten Lehmann 02 Apr '06

02 Apr '06

Hello, I'm using dovecot-1.0.beta3. When I shutdown dovecot (kill -term on the master-pid) the main process disappears, but all the child processes still remain. Why doesn't dovecot kill them as I shutdown the master-process? When I shutdown mysql, all child processes will be shutdown, too. When I shutdown apache, all child processes willbe shutdown, too. Thats what I expect on every application. Usually there is no need to shutdown dovecot. But for some reasons, from time to time 50 and more processes of one user are running and I don't know how else to get rid of them. I don't like to kill the child processes always manually. Regards Marten

Re: [Dovecot] Quick question. Thunderbird/Outlook = no love.
by Charlie Davis 02 Apr '06

02 Apr '06

Ok, it worked once, then stopped working. To get away from maybe it being a thunderbird setup issue, I made a little php script. And now I have an error that didn't show up in the dovecot log even though I have auth_debug and auth_verbose set to yes. Here's what the imap socket returned to the php script: Array ( [0] => Certificate failure for 10.0.0.208: self signed certificate: /OU=IMAP server/CN=imap.example.com/emailAddress=postmaster@example.com ) So, I gotta setup my certificate stuff which I can do, But couldn't this have shown up in the dovecot log somehow? -Charlie ----- On Saturday, April 1, 2006 fishgills(a)fishgills.net wrote: > Turns out some Anti-Virus email scanners don't support TLS. > > Sorry again!

[Dovecot] postfix 2.3 SMTP AUTH and Outlook
by Antonin Karasek 01 Apr '06

01 Apr '06

Hi all, I just maked $SUBJECT to run. The main problem was, that in Dovecot are by default enabled only plain digest-md5 and cram-md5 authentication mechanisms. While MS Outlook knows only "LOGIN" mechanism. So, Outlook users wasn't able to use SMTP AUTH. The solution is to change a line in dovecot.conf: mechanisms = plain digest-md5 cram-md5 to: mechanisms = plain digest-md5 cram-md5 login I suggest Timo to change the default configuration, and the page http://wiki.dovecot.org/Authentication -- more precisely the line "LOGIN: Similiar to PLAIN, not very useful. [in 1.0-tests only]" -- I think, that this line is a little confusing. Becouse since one can use Dovecot for SASL authentication, "LOGIN" is starting to be useful (because of the M*S* bullshit). Regards Tony

[Dovecot] Fedora 4: x86_64 different build options than i386?
by fishgills＠fishgills.net 01 Apr '06

After successful testing on our 32-bit machine using the rpm, I'm installing dovecot on our Fedora 64-bit machine using that rpm. In the log file I get: dovecot: Mar 31 15:34:16 Error: auth(default): Unknown database driver 'mysql' I see this: # dovecot --build-options Build options: ioloop=poll dnotify ipv6 openssl Passdb: checkpassword pam passwd passwd-file shadow Userdb: checkpassword passwd passwd-file static and dovecot is in: /usr/local/sbin/dovecot But on my 32-bit Fedora machine, also installed from the rpm, I get this: # dovecot --build-options Build options: ioloop=poll dnotify ipv6 openssl mysql postgresql sqlite Passdb: checkpassword ldap pam passwd passwd-file shadow sql Userdb: checkpassword ldap passwd passwd-file sql static and dovecot is in: /usr/sbin Shouldn't the 64-bit machine have the same build-options? What can I do to make it right? Do I *have* to build it from a tarball? Charlie Davis

[Dovecot] Quick question. Thunderbird/Outlook = no love.
by Charlie Davis 01 Apr '06

01 Apr '06

Are there any how-tos or documentation on getting dovecot to be thunderbird/outlook friendly? Thunderbird can connect about 20% of the time, the other 80% of the time, I Get the error: "You may need to connect via SSL or TLS. Please check the account settings for your mail server." I have my thunderbird setup to do TLS. I've put it on the TLS if available as well, still no love. Dovecot logfile contains: dovecot: Mar 31 17:25:19 Info: imap-login: Aborted login: rip=10.0.0.4, lip=10.0.0.208, TLS dovecot: Mar 31 17:25:24 Info: imap-login: Aborted login: rip=10.0.0.4, lip=10.0.0.208, TLS Nothing else.

[Dovecot] Repot: Problems with Fedora core 5, Dovecot and Thunderbird - is this a Dovecot bete3 bug?
by Robert Hart 31 Mar '06

31 Mar '06

Hi One Wed I posted the following message and have had no replies. I am reposting as I think this is a Dovecot bug but I am not sure. If anyone can assist on this I'd be most grateful. Tks ----------------------------------------------------- Hi I am testing FC5 before upgrading my main server and I am getting errors with dovecot 1.0 beta3 - both the distributed RPM and also the one at ATrpms and thunderbird (the distributed version which is thunderbird-1.5-6) I am running both dovecot and thunderbird on the same machine, pointing thunderbird at 127.0.0.1 for its imap server. The symptoms are an inability to access mail - thunderbird just keeps on trying and getting nowhere and even if I shut down thunderbird on the client, it still leaves processes running that have to be killed by hand. In the maillog I get Mar 29 09:17:25 bree dovecot: imap-login: Login: user=<hartr>, method=plain, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured Mar 29 09:17:25 bree dovecot: imap(hartr): mbox sync: UID inserted in the middle of mailbox /var/mail/hartr (8 > 1, seq=2, idx_msgs=4) Mar 29 09:17:25 bree dovecot: imap(hartr): file mbox-sync-update.c: line 55 (mbox_sync_move_buffer): assertion failed: (ctx->mail.offset + ctx->mail.space <= ctx->hdr_offset + pos || ctx->mail.offset > ctx->hdr_offset + pos + have) Mar 29 09:17:26 bree dovecot: child 14242 (imap) killed with signal 6 When I point this thunderbird at my main (dovecot 0.99) server everything is fine, which seems to suggest that this is a dovecot problem and not a thunderbird one. Can anyone give me any pointers on this please as it's a show stopper for upgrading my main server. Tks -- Robert Hart hartr(a)interweft.com.au +61 (0)438 385 533 http://www.hart.wattle.id.au

[Dovecot] Courier to Dovecot Maildir converstion
by Jeff S. 31 Mar '06

31 Mar '06

Hello, I am running Dovecot 0.99 on OpenSuse 10.0. Previously, I was running courier IMAP with vpopmail on Suse 9.3. In the process of the change, I decided to sing MySQL to authenticate the users, provide home dir, uid and gid. I tar'ed up the old mail directories, moved them to the new server, added a new user and group to own the files, set the files uid/gid to match the values in the db. Next, I followed the Migration directions on http://wiki.dovecot.org/Migration. I can successfully authenticate the new users, have no errors in the log file but when I am logged in I only see the Inbox. There should be other folders as well as mail in the inbox. No errors in the log files. Any ideas?

[Dovecot] Authentication Problem MD5 hashs
by Fabrizio Steiner 31 Mar '06

31 Mar '06

Hello I've migrated to dovecot-1.0beta3 and I have taken over the password files from an older system. For some reason the md5 hashs have "[" chars in the salt. For example like this $1$[xxxXX[E$bg/d4JdSSf2kTL8sXXxXXX Now the problem is that in the file src/auth/db-passwd-file.c on line 43 for libpam-pwdfile compatibility it will be searched for "[" to find the type of the password hash. Then only the hash up to this point will be used in future for comparing the passwords. The problem line. p = pass == NULL ? NULL : strchr(pass, '['); I changed the behavior to always use the complete hash out of the file because I don't use pam. Does anyone know if [ chars are allowed in md5 hashs? Kind Regards Fabrizio Steiner

[Dovecot] Custom Quotas
by Andrew Barrow 31 Mar '06

31 Mar '06

Greetings I'm currently working on a design, to integrate an IMAP server into our existing mail architecture. It's proving to be a difficult exercise, mainly because of how we structure our quotas. In our system, the quota covers more than just email. We have a single quota that covers email, ftp directory, and personal homepage. The quota is stored in a mysql database, in a werid table structure. The quota allocation is stored against the user, while the quota usage is stored in 3 rows per user, in a seperate table; One row each for www, email, and ftp per user. I'm currently trying to figure out how we could integrate this quota into Dovecot. I'm quite happy to write plugin to handle updating the quota in our system, but I have no idea where to start. Any information you could provide on updating a quota in a third party system would be much appreciated. Thanks for you help.

[Dovecot] Dovecot abort while selecting INBOX
by Joshua Wise 31 Mar '06

31 Mar '06

Hello all, Recently, I was setting up SpamAssassin and procmail on my system (used to run Courier, and was converted using Courier convert scripts). I was setting up a rule in PINE to filter all previously marked SPAM messages into a folder, when I suddenly got disconnected from the IMAP server. I attempted to reconnect, but any attempts to access my INBOX would disconnect me. I looked in /var/log/mail.log on my server, and found this: Mar 26 12:42:17 dashnine dovecot: imap-login: Login: user=<joshua>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Mar 26 12:42:17 dashnine dovecot: imap(joshua): Trying to allocate 0 bytes Mar 26 12:42:17 dashnine dovecot: child 31035 (imap) killed with signal 6 Looks like Dovecot aborted. I grabbed a tcpdump of the event after turning off SSL, which is available at http://joshuawise.com/pine.imap.tcpdump . My system is, summarized: * A Linux x86 machine: Linux dashnine 2.6.12.3 #2 Sun Aug 7 18:56:14 EDT 2005 i686 GNU/Linux * A Debian machine: testing/unstable * Running Dovecot from Debian: 1.0.beta3 * Converted from Courier using convert scripts * Using Postfix and Procmail * Using Maildirs in home directories (although in this case, lrwxrwxrwx 1 joshua joshua 23 Mar 11 22:08 Maildir -> /media/Maildirs/joshua/) * Using PINE connecting to Dovecot on localhost to access email Let me know if you want more information, or if you want me to try anything in particular. Thanks, joshua

[Dovecot] Confused about what MTA, MDA, IMAP/POP server to use
by Netlink Tech 31 Mar '06

31 Mar '06

Hello...I'll TRY make this short. This post is not specific to Dovecot...but many subscribers to this list have probably been down this road. (private replies welcome if you want it to go off list) I currently use Sendmail with MailScanner, SpamAssassin, ClamAV, Procmail, and qpopper for POP3 (hash mail dirs for mbox files)on RedHat 9 server. Roaming users currently only have the option of UebiMiau webmail interface to POP3 (doesn't work well) I will be moving to a server with Fedora Core 5.(x86_64) Things I would like to accomplish: 1) Move to maildir mailbox format (currently large mbox files cause I/O flushing errors and problems for users retrieving). 2) Use squirrelmail for webmail (IMAP) (local or roaming users) 3) Enable local users (ones with current accounts on the server) to continue to use their current client setup. 4) Enable any user to use the webmail interface to retrieve/send email. 5) Enable roaming users (ones connected from any location) to use Outlook Express or similar with SMTP_Auth and port 587 for message submission and POP3/IMAP. 6) Enable mail quota. I want the current users to use their current settings (unless they roam...then require that they use webmail or SMTP_Auth and port 587), but moving forward with new users, I have no reason to give them shell access/system accounts....so I was thinking virtual users using user@domain and storing their auth information in mysql db. (mysql will be used for radius...so it is already running on the server). Because I am trying to figure out how to keep the existing users system accounts and move forward with new users only having virtual accounts (just mail access with no login), I don't think I can use file system quotas. I have used Sendmail for 10 years, so I am familiar with it and it has been very stable for me. (so I prefer to stick with it if I can) I rely heavily on MailScanner to scan/mark/clean virus and Procmail to filter marked spam. Qpopper is on the way out...A couple of weeks messing with the test server and I already love Dovecot. Questions: 1) Recommendations please: How to accomplish with what configuration. 2) Quotas? 3) SMTP_Auth using Mysql for virtual users? (works fine with PAM/system passwords) Sorry for not being Dovecot specific on the list. Curt

Re: [Dovecot] Support for Kmail maildir format

Don't add it in the TODO - you've already done it (basically). I'd cobbled together a real kludge to use the dovecot-shared permissions on the subscriptions file (kinda - only the group permissions, not the user) and was about to post it to the list when I came across the way you'd already handled it. The subscriptions file is stored in the folder pointed to with the "CONTROL" directive - I just put this to a separate place for every user and it works fine. The only thing that's left is getting this added to the Wiki - I don't think anyone's done that yet.

[Dovecot] Realm Stripping
by Michael Baird 30 Mar '06

30 Mar '06

I saw some discussion on this from the middle of last year. Looking through the archives, there didn't seem to be a full solution using a standard dovecot configuration. Did this issue get resolved within dovecot? Will it strip domains from the login presented by the customer. I currently am using dovecot for imap with a webmail system (I strip the domain there before it hits dovecot), but I'd like to replace qpopper with dovecot's pop3, just need to work out the domain stripping bit.

[Dovecot] Solution to Dovecot-lda configure problem on RHEL4/FC4

Hello, After a long break from Dovecot I finally managed to compile Dovecot-lda on RHEL 4 x86_64 platfrom. For some reason $LIBICONV translates to a @LIBICONV@ on config.status which generates loop for sed. Solution is to manually edit "configure" after autogen.sh. In configure change line s,@LIBICONV@,$LIBICONV,;t t to s,@LIBICONV@,,;t t After this configure finishes succesfully. Tomi

[Dovecot] [PATCH] integrate dovecot LDA into dovecot
by Timo Sirainen 29 Mar '06

29 Mar '06

(ops, messed up the first send, again) > what do you think about replacing the deliver source in dovecot with > deliver from dovecot LDA? It would make it much easier to compile and > deploy dovecot LDA. It would, but I don't want that, at least not currently. My plan is to merge them in some way at some point, but the Sieve code will always be kept out of the main Dovecot tarball as some kind of plugin. The Sieve code is something I don't really want to touch myself, and I don't want it to be included in Dovecot's "1000 EUR for security hole" competition (or whatever it should be called). Since the patch was a bit too large, I didn't accept your original mail to the list.

[Dovecot] new mails don't always show
by Bjoern Rost 29 Mar '06

29 Mar '06

Hi, I am having some trouble with dovecot (0.99.14) and maildir. Some users are reporting that sometimes, they don't get (pop3, various clients) new mails for a while even though they should. I checked and confirmed this: mails were delivered by MTA (sendmail, procmail). But when the problem existed, the new mails were in cur/, not new/ and dovecot would not report any new messaged to the client. A 'solution' was to send another mail to the same account, and ususally this would end up in new/ On the next fetch, this new message and the new ones from cur/ are downloaded. I also had the same problem with imap and evolution today. My inbox showed as empty but there were many messages in cur/ I could access all other folders without a problem during this period. Again, a simple mail to myself 'solved' this. This behaviour does not happen all the time and I don't know how to trigger/reproduce it. Just the relevant (imho) parts of dovecot.conf: login_process_size = 256 login_processes_count = 64 login_max_logging_users = 1024 default_mail_env = maildir:%h/Maildir client_workarounds = outlook-idle oe6-fetch-no-newmail outlook-pop3-no-nuls everything else is set to default values Any ideas/help?

[Dovecot] Too many links

Hi all, I've a problem during a big migration to dovecot. I'm not sure that is a really a dovecot bug ... but maybe somebody here know one solution ... I have more than 150000 imap account to migrate from an obscure mail system based on a database to an imap/dovecot system. During the migration (simple but very long process) I get a "Too many links" error from dovecot. This error is not obscure but I'm unable to find a solution with this error on google. I kown the /proc/sys/fs/file-max for increase the number of open file, but it's not the problem here. This probleme occure with more than 130000 directory and more than 350000 file. Have you an idea ? Thank, Cyril Feraudet

[Dovecot] Problems with Fedora core 5, Dovecot and Thunderbird

29 Mar '06

Hi I am testing FC5 before upgrading my main server and I am getting errors with dovecot 1.0 beta3 - both the distributed RPM and also the one at ATrpms thunderbird (the distributed version which is thunderbird-1.5-6) I am running both dovecot and thunderbird on the same machine, pointing thunderbird at 127.0.0.1 for its imap server. The symptoms are an inability to access mail - thunderbird just keeps on trying and getting nowhere and even if I shut down thunderbird on the client, it still leaves processes running that have to be killed by hand. In the maillog I get Mar 29 09:17:25 bree dovecot: imap-login: Login: user=<hartr>, method=plain, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured Mar 29 09:17:25 bree dovecot: imap(hartr): mbox sync: UID inserted in the middle of mailbox /var/mail/hartr (8 > 1, seq=2, idx_msgs=4) Mar 29 09:17:25 bree dovecot: imap(hartr): file mbox-sync-update.c: line 55 (mbox_sync_move_buffer): assertion failed: (ctx->mail.offset + ctx->mail.space <= ctx->hdr_offset + pos || ctx->mail.offset > ctx->hdr_offset + pos + have) Mar 29 09:17:26 bree dovecot: child 14242 (imap) killed with signal 6 When I point this thunderbird at my main (dovecot 0.99) server everything is fine, we seems to suggest that this is a dovecot problem and not a thunderbird one.

[Dovecot] Timeout when receiving messages with attachment
by spart cus 28 Mar '06

28 Mar '06

Hi guys, just recently got a problem with my mail server. My clients are comlaining that whel receiving theyre emails after 7 mails received suddenly the connection has timeout. Another scenario is with attachments. Sending 1MB of attachment is not a problem, but receiving this attachement is. Suddenly it timeout for some while. Anyone has a solution for these ? tnx --------------------------------- Yahoo! Messenger with Voice. PC-to-Phone calls for ridiculously low rates.

Hello, today our dovecot imap server died. The following message appeared in the logfile: dovecot: Mar 23 07:00:58 Error: pipe() failed: Too many open files We have one dovecot instance for pop3 and one for imap, so while the pop3-service was still available, the imap-service was not running any more. I've seen a lots of users keeping there imap-connections idle for hours, often more than one per mailbox. How can I limit this? Can I limit the maximum time a connection can be open? Regards Marten

[Dovecot] Re: OS X-centricities? Too many files, temp, indexes, etc...
by Roger Weeks 27 Mar '06

27 Mar '06

We're an ISP with approximately 9000 email customers. Up until early in January our primary mail servers ran on OS X, with exim as the MTA and courier-imap as the pop/imap server. We had continual problems with courier on OS X. The load it generates on the machine is horrible. You'll get absolutely no help from the courier mailing list or developers with OS X issues. When we started evaluating Dovecot, we first attempted it on OS X, however we were unable to get it running in an NFS environement on OS X in any sort of stable manner. I can't recommend highly enough getting off of OS X if you can for mail services. We went to Red Hat machines, and they have been amazingly stable and reliable. I love OS X, and use it for other things, but it makes a bad mail server at least for the volume of mail we process. -- Roger J.

[Dovecot] LDA sieve library
by Luca Corti 27 Mar '06

27 Mar '06

Hello, is the LDA linked against the Cyrus SIEVE library or against the fork at libsieve.sourceforge.net ? It seems Cyrus SIEVE from src/libsieve/README in the lda sources. libsieve seems to be better suited for inclusion in non-cyrus software and should be completely independent from libcyrus. The README for cyrus version of libsieve also states that: "It should compile without libcyrus, but then it does not implement the "address" test." thanks -- Luca Corti PGP Key ID 1F38C091 BOFH excuse of the moment: Interference from the Van Allen Belt.

Hi! I installed Dovecot from the FreeBSD port. I have about 20 users on this machine and used popper before switching. I get a lot of error messages like: dovecot: Mar 21 10:03:41 Error: pop3(xxx): mbox sync: UID inserted in the middle of mailbox /var/mail/xxx (37326 > 35874, seq=1, idx_msgs=26) dovecot: Mar 21 10:06:17 Error: imap(yyy): mbox sync: UID inserted in the middle of mailbox /var/mail/yyy (37352 > 36945, seq=1, idx_msgs=2) dovecot: Mar 21 10:06:18 Error: imap(yyy): kevent(1) in io_loop_handle_add() failed: Bad file descriptor dovecot: Mar 21 10:06:18 Error: imap(yyy): kevent(1) in io_loop_handle_remove failed: Bad file descriptor dovecot: Mar 21 10:06:22 Error: imap(yyy): mbox sync: UID inserted in the middle of mailbox /var/mail/yyy (37354 > 36945, seq=1, idx_msgs=205) Most of the errors are the mbox sync messages.

[Dovecot] %d empty even though username has @domain
by William Ross 27 Mar '06

27 Mar '06

hello, Sorry to jump straight in with a question, but I've searched the archive[0] and I'm pretty sure the answer's not there. I'm using dovecot to replace courier imap, so authentication is by vpopmail and the Maildirs are stored in the usual domains/domain/user/ Maildir. Everything seems to work very well, and setting it up has been easy, so thank you very much for that. I have only one problem left: %d is empty when interpolated into default_mail_env. I expect there's something obvious I'm doing wrong, but it's hard to tell because the wiki isn't always up to date (i'd be happy to update the vpopmail sections once this is working): Config has this [1]: default_mail_env = maildir:/home/vpopmail/domains/%d/%n/Maildir and i log in over imaps with the account i'm using for testing: username: sysadmin(a)spanner.org password: ... Authentication seems to work perfectly, but then the logs show: dovecot: Dec 05 12:24:59 Info: imap(sysadmin): maildir: root=/home/ vpopmail/domains//sysadmin/Maildir, index=/home/vpopmail/domains// sysadmin/Maildir, control=, inbox= any suggestions, please? thank you, will [0] This has come up before: http://dovecot.org/list/dovecot/2005- June/007530.html [1] the rest of dovecot.conf, less comments: base_dir = /var/run/dovecot protocols = imaps log_path = /var/log/dovecot mail_debug = yes protocol imap { } protocol pop3 { } auth_verbose = yes auth default { mechanisms = plain passdb vpopmail { args = } userdb vpopmail { } userdb prefetch { } user = root } namespace private { separator = . prefix = INBOX. inbox = yes } default_mail_env = maildir:/home/vpopmail/domains/%d/%n/Maildir pop3_uidl_format = %v-%u ssl_cert_file = /usr/local/ssl/certs/dovecot.pem ssl_key_file = /usr/local/ssl/private/dovecot.pem

Re: [Dovecot] Dovecot 1.0 beta3 and SUBSCRIBE

Thanks but for mbox it is ".subscriptions", "subscriptions" is for maildir, but I found the BUG !!! ~/mail/.subscriptions is on an NFS mounted filesystem, it keeps on getting deleted... does not like NFS (the files are renamed .nfsXXXXX when deleted) if I patch the code to get it on a local filesystem, like my indexes (in storage->index_dir instead of storage->dir): /var/indexes/%u/.subscriptions then it stays alive and work.

[Dovecot] Clash between multiple authentication databases (security problem?)
by dovecot-ri 27 Mar '06

27 Mar '06

Hi all, I just installed dovecot-1.0_beta2 and love it! However, I've run into issues using multiple authentication databases. I use both pam (for users on my system) and sql (for virtual users). I've noticed that if I have system user "userabc" and virtual user "userabc(a)otherdomain.com" (two distinct users) and my "auth default" section contains these passdb/userdb entries in this order (the order in the example config): passdb pam passdb sql userdb pam userdb sql then when userabc(a)otherdomain.com logs in, he'll get the system user userabc's mail instead of his own. It appears that the sql password check succeeds, then Dovecot grabs the home directory from pam, NOT sql. I can work around this by setting up "userdb prefetch" and adding that section *before* "userdb pam". If I put "userdb prefetch" after "userdb pam" or after "userdb sql", then Dovecot doesn't actually do the prefetch (which causes an error since Dovecot issues the default SQL query for "user_query", which my MySQL database doesn't like). Is there a safer way to do this? If not, should there be? Thanks! Richard ====================================================== complete working dovecot.conf: ====================================================== first_valid_uid = 900 mail_debug = yes default_mail_env = maildir:%h/.maildir maildir_copy_with_hardlinks = yes protocol imap { login_greeting_capability = yes } protocol pop3 { } auth_debug = yes auth default { mechanisms = plain passdb pam { args = "*" } passdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb prefetch { } userdb passwd { } userdb sql { args = /etc/dovecot/dovecot-sql.conf } user = root } ====================================================== dovecot-sql.conf: ====================================================== driver = mysql connect = host=/var/run/mysqld/mysqld.sock user=mail password=** dbname=mail default_pass_scheme = SSHA password_query = <query that returns user, password, userdb_home, userdb_uid, userdb_gid>

[Dovecot] Some moved or copied messages get stuck in tmp
by Luis Meléndez 26 Mar '06

26 Mar '06

Hello. I have seen in recent posts that there are other people with this problem, and it is very important for me, as it is the only cause for not putting Dovecot in production in all mail servers in my University. When moving/copying messages, some of them get stuck in the tmp directory of the destination folder, effectively lost for the user. I have been tracing the problem, and it looks that it happens with messages that have flags. The others don't have problems. But if I copy/move several flagged messages, one of them is copied, and the others are kept in tmp. In maildir-save.c there is the following comment: /* if we have flags, we'll move it to cur/ directly, because files in new/ directory can't have flags. alternative would be to write it in new/ and set the flags dirty in index file, but in that case external MUAs would see wrong flags. */ that looks like a clue. It happens with CVS versions 20060320 and 20060325 I hace done almost all tests with Thunderbird.

[Dovecot] OS X-centricities? Too many files, temp, indexes, etc...
by Dean Blackburn 25 Mar '06

25 Mar '06

I'm just writing to see if anyone else is seeing the following issues, and particularly if they are running OS X (especially 10.4), and/or have compatible solutions (I've been reading the mailing list quite a bit, and every now and then, I find a solution that just "doesn't work" because of the differences in OS: 1) Too many files open - no plimit command on OS X, so I can't figure out how to increase the max number of open files... Also, are there any alternative means of CLOSING the files? stopping/restarting dovecot didn't seem to help; 2) I was running 1.0beta1 last week, and am now on 1.0beta3, but I'm still not seeing corrupt indexes/other dovecot files rebuilding themselves. I really can't stick with this solution if I'll always have to worry about manually fixing broken caches/indexes. 3) Any advice on fcntl/flock on OS X, particularly? They both appear to work, but I'd prefer to use the fastest/least resource intensive options for everything if possible. Thanks! -deano

Hi, I'm using dovecot 1.0.0beta3 on a RHEL4 x86_64 server. I'm seeing this error each and every time a user checks his emails : Mar 15 18:19:34 s1 dovecot: pop3-login: Login: user=<user@domain>, method=PLAIN, rip=::ffff:195.x.x.x, lip=::ffff:195.x.x.x Mar 15 18:19:34s1 dovecot: pop3(user@domain): Corrupted transaction log file /home/vmail/domain/user/dovecot.index.log: unexpected end of file while reading header Mar 15 18:19:34 s1 dovecot: pop3(user@domain): Logout. top=0/0, retr=0/ del=0/2, size=1213 From my basic testing, this seemed harmless. But after putting this in production, it appears that when emails are retrieved, long ones always get truncated after a few kB, changing attachments into garbage :-( Has anyone seen this problem before?

[Dovecot] Segfault when parsing configuration on x86_64

Hi, Using the exact same build of 1.0.beta3, one i386 and the other x86_64, I get segfaults upon startup with the x86_64 version when using the exact same dovecot.conf file. Here is the error : # dovecot -F Unexpected eof found when reading file 'UNOPENED' (Errcode: 0) Segmentation fault (core dumped) And the backtrace (I don't have symbols for all libs, sorry) : (gdb) bt #0 i_stream_next_line (stream=0x52c3a8) at istream.c:182 #1 0x000000000040e345 in i_stream_read_next_line (stream=0x52c3a8) at istream.c:201 #2 0x000000000040aaa9 in settings_read (path=0x41798e "/etc/dovecot.conf", section=0x0, callback=0x409580 <parse_setting>, sect_callback=0x409a50 <parse_section>, context=0x7fbffff880) at settings.c:222 #3 0x000000000040a0e1 in master_settings_read ( path=0x41798e "/etc/dovecot.conf", nochecks=false) at master-settings.c:1159 #4 0x000000000040875a in main (argc=2, argv=0x7fbffffa18) at main.c:762 #5 0x0000003d4341c4bb in __libc_start_main () from /lib64/tls/libc.so.6 #6 0x000000000040357a in _start () #7 0x0000007fbffffa08 in ??

() The really weird part is that I've managed to get my dovecot.conf in a state where the problem no longer happens, but simply adding a line with '#', or removing trailing spaces (normally harmless) on some config lines makes the error re-appear. My quick guess would be that something is wrong with the config file parser on 64bit archs... Actually, I've just made some more tests, and it is "partially" reproducible on i386. In this part of my configuration : auth default { mechanisms = plain passdb sql { args = /etc/dovecot-mysql.conf } userdb sql { args = /etc/dovecot-mysql.conf } } There is a trailing space on both "args = ..." lines. Well, if I remove them, I get this message with the i386 build. When I put them back, all is fine again.

[Dovecot] Per-user "Seen" flags with shared namespace stored as maildir?
by Mark Lidstone 25 Mar '06

25 Mar '06

Hi all, I was wondering if the above was possible. I know that the "seen" flag is stored in the filename, but was wondering if anyone knew of a way to separate it out? I know this would strictly-speaking break maildir compatibility, but it would be extremely useful for shared folders. I've been given the task of replacing the (extremely heavily used) shared folders functionality of our Exchange server and have almost everything working. I have authentication working against AD, shared folders, per-user subscriptions, "mail enabled folder" functionality and seem to have sorted all the other permissions issues I've been having. Apart from a nice easy-to-use front end for changing folder permissions this is the last thing I can think of that I need to look into before I can show this to my boss.

[Dovecot] Authentication without password
by Feraudet Cyril 25 Mar '06

25 Mar '06

Hi all, for one of my developpements, I need to be able to connect an IMAP server with a login but without password. (I use dovecot 1.0.beta3) For the userdb, I use "userdb static" : userdb static { args = uid=114 gid=114 home=/mydev/mail/%u } But I don't know how to allow IMAP connection by my application without password. I won't connect to a database, having a user/password file or something like this ... I think to use "passdb checkpassword" to call a fake authentication script .... Anyone have a better idea ? Thanks, Cyril Feraudet

[Dovecot] How Can I Add New Flags
by Sezai KARATOZ 25 Mar '06

25 Mar '06

Hi all, I am new in Dovecot. I wanna use Dovecot in the big mail system about 4 million active or passive users. We use recently Courier Imap, but search mails process is so slowly. I tried Dovecot that it is better then Courier so much. But I have a problem with integration Dovecot to my system. I am using some extra flags in mails to mark them from others. For example I use a private flag "M" to understand it that this mail come from us as newsletter. I make some changes in code, but unfortunately I could'nt add this flag to Dovecot correctly. Please help me it that how can add this flag. I use maildir type Thanks, Sezai

[Dovecot] Shared namespaces
by Mark Lidstone 25 Mar '06

25 Mar '06

Hi all, I'm trying to replace the "Public Folders" functionality in Exchange server. At first I thought it'd be something easily do-able with an IMAP server so I immediately thought of Dovecot. I setup what I though would work and things started to go a little screwy with subscription settings and the like. I started off by making a public maildir folder (in /home/public/Maildir) and setting the namespaces up in /usr/local/etc/dovecot.conf like this: namespace private { separator = / prefix = INBOX/ location = maildir:%h/Maildir inbox = yes } namespace public { separator = / prefix = Public/ location = maildir:/home/public/Maildir inbox = no hidden = no } The folder /home/public/Maildir has owner root:users and mode 770, and the file dovecot-shared in there has the same owner and mode 660. I logged with Thunderbird as user 1 and everything seems to work fine. However, when I logged in as user 2 I was getting all kinds of errors. On checking the permissions of /home/public/Maildir/subscriptions it was user1:user1 with mode 600. So then I thought "well, I'll change it to user1:users 660 and then everyone should be able to change it". I was very wrong. Whenever someone changed it, the ownership changed to userx:userx 600. Even when I tried setting the ownership to root:users and mode to 640, anyone could change it and set it to their own name (thus preventing anyone else from using it). To be perfectly honest, I'd ideally like to give people separate subscription settings anyway. I thought about symlinking the folders in, but that makes it a manual process to add new folders to everyone's maildirs. Can anyone please give me any pointers?

[Dovecot] [PATCH] OpenSSL RNG initialization
by Vilmos Nebehaj 25 Mar '06

25 Mar '06

Hi, dovecot tries to use OpenSSL's PRNG to generate random numbers if there is no /dev/urandom found. Unfortunately, it is flawed in its present form, since the PRNG is not seeded before RAND_bytes() is called in src/lib/randgen.c (on systems which have /dev/urandom, OpenSSL automatically seeds its PRNG from the urandom device). Here's a patch to address this issue: it tries to seed the PRNG if there is no /dev/urandom present (which is likely the case if dovecot uses OpenSSL's RAND API). It can also be fetched from http://innoidea.com/~vili/dovecot_rng_init.diff -Vilmos Nebehaj Index: configure.in =================================================================== RCS file: /home/cvs/dovecot/configure.in,v retrieving revision 1.266 diff -u -r1.266 configure.in --- configure.in 28 Feb 2006 08:36:41 -0000 1.266 +++ configure.in 10 Mar 2006 17:15:01 -0000 @@ -358,7 +358,8 @@ AC_CHECK_FUNCS(fcntl flock lockf inet_aton sigaction getpagesize madvise \ strcasecmp stricmp vsnprintf vsyslog writev pread \ setrlimit setproctitle seteuid setreuid setegid setresgid \ - strtoull strtouq setpriority quotactl getmntent kqueue kevent) + strtoull strtouq setpriority quotactl getmntent kqueue kevent \ + getrusage) dnl * I/O loop function have_ioloop=no Index: src/lib/lib.h =================================================================== RCS file: /home/cvs/dovecot/src/lib/lib.h,v retrieving revision 1.20 diff -u -r1.20 lib.h --- src/lib/lib.h 25 Sep 2005 10:44:04 -0000 1.20 +++ src/lib/lib.h 10 Mar 2006 17:15:02 -0000 @@ -20,6 +20,13 @@ # include <stdint.h> /* C99 int types, we mostly need uintmax_t */ #endif +#ifdef HAVE_SYS_TIME_H +# include <sys/time.h> +#endif +#ifdef HAVE_SYS_TIME_H +# include <sys/resource.h> +#endif + #include "compat.h" #include "macros.h" #include "failures.h" Index: src/lib/randgen.c =================================================================== RCS file: /home/cvs/dovecot/src/lib/randgen.c,v retrieving revision 1.13 diff -u -r1.13 randgen.c --- src/lib/randgen.c 6 Jan 2005 19:08:19 -0000 1.13 +++ src/lib/randgen.c 10 Mar 2006 17:15:03 -0000 @@ -81,6 +81,42 @@ return buf; } +static void random_init_rng(void) +{ + int counter = 0; + struct timeval tv; +#ifdef HAVE_GETRUSAGE + struct rusage ru; +#endif + + /* + * If the RNG is already seeded, we can return + * immediately. + */ + if (RAND_status() == 1) + return; + + /* + * Else, try to seed it.

[Dovecot] first crack at auto-trash plugin
by David Powers 25 Mar '06

25 Mar '06

I have written an alpha version of an auto trash plugin for dovecot. When compiled in any mail expunged from a non-Trash folder is moved to a folder named Trash. As of yet the folder is not created if it doesn't exist (the process fails before expunge). I would appreciate feedback of any sort. In addition, I am currently getting an error I haven't been able to puzzle out in the logs when it runs: Mar 21 15:22:01 david dovecot: imap(david(a)grayskies.net): Timeout leak: 0x807fad0 I see that it seems to relate to transactions somehow, but my few hours of playing with dovecot haven't given me the answer - so ideas/patches to the code would also be nice. You can grab it here: http://wrath.grayskies.net/tarballs/auto-trash.tar.gz -David

[Dovecot] Method of archiving mail?
by Stephen Allen 24 Mar '06

24 Mar '06

Hello I have a situation in which a number of users have 10,000+ messages in the maildir, going back a few years. I'm not a fan of this many files lying around so I'd like to set up some kind of archiving, but one that will allow user's access to the old mails should they wish to see them. I thought of a cron job trying to sift through messages pulling those what were older than x days, then writing some script to process a request from a user (date/time/from/to/subject/body text) and copy matching messages to a "query" folder in the maildir. However, a) I'm not good at this kind of thing, and b) I have a feeling it's already been done before. Can anyone point me in the right direction please... is their software around to do this already? Many thanks, Steve :)

[Dovecot] Imap Timeouts
by Neil Wilson 24 Mar '06

24 Mar '06

Hi guys, I've got a client running 1.0.beta3 on SuSe 9.3 Everything has been running perfectly since it was installed about 6 months ago, but lately they've had issues with email clients not being able to connect to the IMAP server, until they close their clients(Thunderbird & Outlook) and then re-open them. They have roughly 70 users on their network, so it sounds like it could be too many active sessions at once, but I've tried changing a few things in the config, and so far nothing has resolved this. Any help would be appreciated. Regards.

[Dovecot] Can Dovecot 'slurp' into the INBOX from a mail spool file?
by Daniel Watts 23 Mar '06

23 Mar '06

Hi guys, I have a system whereby I am forced to deal with mbox files of /var/spool/mail/user1 (mbox text file) /var/spool/mail/user2 (mbox text file) etc Their mail homes are maildir format in: /home/user1/Maildir/{cur,new,tmp} /home/user2/Maildir/{cur,new,tmp} etc I can set things up so that the mbox inbox is shown using namespaces: namespace private { separator = / prefix = location = maildir:/home/virtual/%d/home/%n/Maildir/ } namespace private { separator = / prefix = mail/ inbox = yes hidden = no location = mbox:/home/virtual/%d/home/%n/mail/:INBOX=/home/virtual/%d/var/spool/mail/%n } This gives a rather odd folder structure as follows: INBOX Sent Drafts Trash mail/ --- INBOX myfolder1 myfolder2 Both of those INBOXes are actually the same folder. I'd ideally like to hide the mbox namespace entirely so that the user does not see any mbox folders. UW IMAP, with it's mbx format, allows you to just drop in a file called INBOX in mbx format and it will 'slurp' the /var/spool/mail/usersmbox file into the mbx INBOX. Has/could Dovecot have a similar feature whereby you specify a spool folder which is then 'slurped' into the local maildir INBOX? Not sure if I'm being clear enough here - do let me know if not! Much thanks, Daniel

[Dovecot] Losing messages
by Stian Jordet 23 Mar '06

23 Mar '06

Hi, I have been running dovecot cvs happily for.. well.. very, very long now. Don't remember when I switched from 0.99, but it was back in the test-days, long before the alpha's. Anyway, it seems to have been working very well all the time. But recently three of my clients have claimed to have lost mail when moving from Thunderbird. I even experienced it myself once. I'm using Evolution 99% of the time, and have never seen any problems with that - but that doesn't mean the problem only occurs with Thunderbird. When moving mail from one folder to another, everything seems fine, except that the mail isn't in any folder anymore. It _seems_ related to this: Mar 14 14:46:53 buick dovecot: imap(larsmj): Fixed index file /home/larsmj/Maildir/.Junk/dovecot.index: first_recent_uid_lowwater 40 -> 36 Mar 14 14:46:53 buick dovecot: imap(larsmj): Corrupted index file /home/larsmj/Maildir/.Junk/dovecot.index: Duplicate header extension keywords But I'm not sure. Either way I get these lines rather often for some users. What does it mean? Anyone seen anything like it? I really don't like the idea of losing clients mail... I hope someone can shed some light on this. Best regards, Stian

RE: [Dovecot] Shared namespaces - solved
by Mark Lidstone 23 Mar '06

Hi Steffen, I'm using procmail as my LDA and postfix as my MTA. Also, in my case I need all email to any email address at my domain starting with "pr" then some numbers to go into these folders. The reason for this is I'm trying to setup an open-source replacement for our mail-enabled Exchange Public Folders at the moment (can you believe you can't search sub-folders in Exchange Public Folders?!). First I created a fake user with it's own group: adduser public_folders Next, I added all the relevant users to that group: usermod -G public_folders john_smith usermod -G public_folders jon_doe Next, in /home/public_user/.procmailrc I put the following: MAILDIR=/home/public_folders/Maildir # If any mail gets through to this account without having a project number address, # put it in an "Unfiled" folder. DEFAULT=$MAILDIR/.Unfiled/new * # This line just gets me the project number (also makes sure the preceding letters * # are uppercase - otherwise we could end up with separate folders for pr123, Pr123, * # pR123 and PR123. * PROJECT_NUM=`formail -xTo: | egrep -o [pP][rR][0-9]+ | tr '[a-z]' '[A-Z]'` # This is not absolutely necessary, but I prefer to keep logs so I can see where # emails have been stored if anything goes missing. LOGFILE=$MAILDIR/procmail.log # This UMASK setting is basically what you're looking for, Steffen. The mail files # on the disk are stored with mode 660. UMASK=007 # Because these are public folders receiving a lot of mail, I've put in a big message # ID cache. :0 Wh: msgid.log |formail -D 2097152 $MAILDIR/msgid.cache * # Notice that regexps in .procmailrc are case insensitive unless you specify otherwise * :0 H * * ^To: .*PR[0-9]+(a)mydomain\.tld * { * PROJECT_FOLDER=$MAILDIR/.Projects.${PROJECT_NUM} * * # Here I basically check if the folder exists. If not it's created with mode * # 770 - this is also important. * :0 Wic: * * ? test ! -d ${PROJECT_FOLDER} * # Make all the subfolders, or they will be made by dovecot when the first user * # tries to look in there messing up the permissions on that folder. * |mkdir -m 770 -p ${PROJECT_FOLDER}/new;\ * mkdir -m 770 ${PROJECT_FOLDER}/cur;\ * mkdir -m 770 ${PROJECT_FOLDER}/tmp * * # And here I finally store the email * :0: * ${PROJECT_FOLDER} * } Make sure the file has mode 0600 public_folders:public_folders or procmail will ignore it. Next, I had to set the following permission on the public_folders home folder: chmod 770 /home/public_folders Next, I put the following namespace into /usr/local/etc/dovecot.conf: namespace public { separator = / prefix = Public/ location = maildir:/home/public_folders/Maildir:INDEX=%h/Maildir/public_folders/indexes:CONTROL=%h/Maildir/public_folders/control inbox = no hidden = no } Next, I made sure the relevant folder structure existed with the right permissions (I cheated and did this as root): cd /home/public_folders mkdir -p Maildir/new cd Maildir mkdir cur mkdir tmp mkdir -p .Unfiled/new mkdir .Unfiled/cur mkdir .Unfiled/tmp for file in `find`; do chown public_folders:public_folders $file if [ -d $file ]; then chmod 770 $file else chmod 660 $file fi done *Next, I made a file called /etc/postfix/virtual.pcre with the following content: * * /^[pP][rR][0-9]+(a)mydomain\.tld/ public_folders@localhost * *And finally I put the following into /etc/postfix/main.cf: * * virtual_alias_maps = pcre:/etc/postfix/virtual.pcre, hash:/etc/postfix/virtual Then I restarted postfix and away I went. Now when someone sends an email to "pr123(a)mydomain.tld" it gets put into the relevant project folder under the "public _folders" maildir. If you don't need the automated project filing, ignore the lines with a * at the start. I hope someone finds this helpful.

RE: [Dovecot] Shared namespaces - solved

Heh heh heh. Whoops. I've spent a few hours digging around in the source and nearly posted a kludge of a patch I'd written to give a kind of half-baked attempt at getting group-usable subscriptions files. Then I came across something in the source........ In the config file, do something like the following: namespace public { separator = / prefix = Public/ location = maildir:/home/public/Maildir:CONTROL=%h/Maildir/Public inbox = no hidden = no } Notice the "CONTROL=" part of the location line. This tells dovecot where to store "control" files (of which the "subscriptions" file is one). As you can see I have told it to put the control files in each user's home space. This means not only are there going to be no permission problems, but each user can have separate subscriptions (because everyone is using their own "subscriptions" file). Of course I could also have set the CONTROL dir to be something like "/home/public/Maildir/control/%u" so they would all be stored in one place, but I prefer the idea of having it in the user's home folder. After searching the wiki I don't see the CONTROL option explained anywhere. Is there any chance someone could add that in somehow (a link from the SharedFolders page would be extremely useful also).

[Dovecot] Save sent mail on server
by Benjamin 23 Mar '06

23 Mar '06

Hi dovecot list users, currently we have some email accounts which get maintained by different people. If any of this users sends a mail, it is only saved on his local machine, but not on the imap server. But i'll need them to get saved on the mail server for backup purposes and that every user can see which mails have been sent through this account. Is this possible? Thanks in advance Regards Benjamin

[Dovecot] mail shown throught outlook, shows todays date
by bclark 23 Mar '06

23 Mar '06

Hi all I seem to be sitting with an interesting situation where by I need to copy mail from Exchange to dovecot (Maildir) I used a mixture of solution (Moz Thunderbird, fetchmail and outlook) to copy and test the mail. The interesting thing is, once I have some mail on the dovecot, the date displayed on Mozilla is correct, but the mail shown throught outlook, shows todays date (thats for all mail). I logged in squirrel mail, that too correctly displays the date. Almost seems as Outlook (office 2000) looks at the date / time stamp of the file it self as opposed to opening and reading the mail and reading the necassry tags. If anyone could help me understand this (is this a dovecot issue), I would really appreciate it. Kind Regards Brent Clark

[Dovecot] Tiny kqueue specific patch
by Václav Haisman 22 Mar '06

22 Mar '06

Hi, I have noticed from logs that (only handful of occurrences during whole week) sometimes there is some kind of unrecognized event on handle and the branch with i_panic() in ioloop-kqueue.c:io_loop_handler_run() catches it. This patch allows the i_panic() to print some more info about the nature of the unrecognized event so that I can find out what it is about. Since it is really rare event I ask anybody who sees Dovecot dying with "Unrecognized event" in logs to try this patch and report back with the output if it triggers again. The patch is against version 1.beta3.

[Dovecot] One dovecot, multiple domains
by Ben 22 Mar '06

22 Mar '06

Hey guys, I've got dovecot configured to work perfectly for virtual users across different domains. It's great. My problem is that, as far as I can tell, dovecot makes me use one SSL certificate across all my domains. That's not what I want. Is there a way I can get dovecot to use the cert for mail.foo.com when somebody is logging into a foo.com account, and the cert for mail.bar.com when somebody is logging into a bar.com account? Am I missing something obvious, or asking the impoosible?

[Dovecot] Using mbox INBOX with Maildirs?
by Mark Winslow 22 Mar '06

22 Mar '06

Thanks for everybody's tips on the mbox to maildirs converter. I was unaware that Maildirs was a common format not specific to dovecot, so I was searching using a dovecot keyword. I'm having this problem now with inboxes. I want to use maildirs, but my mail is delivered to an mbox. I can't seem to get dovecot to recognize the inbox location. Is something like: maildir:%h/Maildir:INBOX=/var/mail/%u impossible to use? What I'm trying to do is slowly merge people from mboxes to maildirs, so I have to use the passwd file per user maildirs settings with some sort of recognizeable inbox. I'm using sendmail as my mail server. Do I have to tell that to put the mail in the right inbox format? Thanks. __________________________________ Discover Yahoo!

[Dovecot] compilation and installation of dspam-plugin
by Stefan Schmidt 21 Mar '06

21 Mar '06

hello johannes, i just discovered your wonderful plugin for dovecot. it was pretty much exactly what i was looking for, only that i didn't know that yet :) "Instead of moving mail into special folders, the user has two actions available: moving it out of the SPAM folder and moving it into the SPAM folder. The dovecot plugin watches these actions [...] and tells dspam that it made an error and needs to re-classify the message, depending on the action the user took. The user can now move the message directly into whatever folder she choses, and it all works. [...]" i think this is the most usable and intuitive approach to dspam-training i have seen so far and would love to integrate dspam with this plugin into my current setup (postfix + maildrop + dovecot). i have installed dovecot via package from the debian stable section [1] therefore i am currently using version 0.99.14 in my setup. despite this difference in version i gave your betacode [2] a try together with the source of the corresponding dovecot-version [3], hoping it wouldn't crash and burn when used with my earlier version of dovecot. but i didn't get to the point where i could actually testdrive it. i tried compiling the plugin with the instructions contained in the file, but the compilation didn't suceed. ---------------------------------------------------------------------- stefan@myserver:~/sources/dovecot-dspam-plugin/dovecot-1.0.beta3/plugin$ gcc -fPIC -shared -Wall -I../src/ -I../src/lib -I.. -I../src/lib-storage -I../src/lib-mail -I../src/lib-imap -I../src/imap/ -DHAVE_CONFIG_H spam_plugin.c -o spam_plugin.so In file included from ../src/imap/common.h:4, from spam_plugin.c:32: ../src/lib/lib.h:6:22: config.h: No such file or directory In file included from ../src/lib/lib.h:23, from ../src/imap/common.h:4, from spam_plugin.c:32: ../src/lib/compat.h:31:4: #error uoff_t size not set In file included from /usr/include/sys/socket.h:35, from ../src/lib/compat.h:80, from ../src/lib/lib.h:23, from ../src/imap/common.h:4, from spam_plugin.c:32: /usr/include/bits/socket.h:36: error: conflicting types for `socklen_t' ../src/lib/compat.h:51: error: previous declaration of `socklen_t' In file included from /usr/include/netinet/in.h:23, from ../src/lib/compat.h:81, from ../src/lib/lib.h:23, from ../src/imap/common.h:4, from spam_plugin.c:32: /usr/include/stdint.h:111: error: conflicting types for `uint_fast32_t' ../src/lib/compat.h:46: error: previous declaration of `uint_fast32_t' /usr/include/stdint.h:141: error: conflicting types for `uintmax_t' ../src/lib/compat.h:38: error: previous declaration of `uintmax_t' In file included from ../src/lib/lib.h:23, from ../src/imap/common.h:4, from spam_plugin.c:32: ../src/lib/compat.h:107: error: redefinition of `struct iovec' In file included from ../src/imap/commands.h:6, from ../src/imap/client.h:4, from ../src/imap/common.h:5, from spam_plugin.c:32: ../src/lib-storage/mail-storage.h:435: error: syntax error before "mail_get_virtual_size" ../src/lib-storage/mail-storage.h:435: warning: type defaults to `int' in declaration of `mail_get_virtual_size' ../src/lib-storage/mail-storage.h:435: warning: data definition has no type or storage class ../src/lib-storage/mail-storage.h:438: error: syntax error before "mail_get_physical_size" ../src/lib-storage/mail-storage.h:438: warning: type defaults to `int' in declaration of `mail_get_physical_size' ../src/lib-storage/mail-storage.h:438: warning: data definition has no type or storage class In file included from ../src/imap/commands.h:7, from ../src/imap/client.h:4, from ../src/imap/common.h:5, from spam_plugin.c:32: ../src/lib-imap/imap-parser.h:45: error: syntax error before "uoff_t" ../src/lib-imap/imap-parser.h:45: warning: no semicolon at end of struct or union ../src/lib-imap/imap-parser.h:45: warning: no semicolon at end of struct or union ../src/lib-imap/imap-parser.h:47: error: syntax error before '}' token ../src/lib-imap/imap-parser.h:47: warning: type defaults to `int' in declaration of `_data' ../src/lib-imap/imap-parser.h:47: warning: data definition has no type or storage class ../src/lib-imap/imap-parser.h:48: error: syntax error before '}' token ../src/lib-imap/imap-parser.h:72: error: field `args' has incomplete type ../src/lib-imap/imap-parser.h:125: error: syntax error before "_imap_arg_literal_size_error" ../src/lib-imap/imap-parser.h:125: warning: type defaults to `int' in declaration of `_imap_arg_literal_size_error' ../src/lib-imap/imap-parser.h:125: warning: data definition has no type or storage class ---------------------------------------------------------------------- just in case it matters: i currently have gcc 3.3.5 installed. greetings, stefan [1] http://packages.debian.org/stable/mail/dovecot-common [2] http://snipurl.com/nvol [3] http://www.dovecot.org/releases/dovecot-1.0.beta3.tar.gz

I'm not sure what you're after but say you want to be able to define folder actions in a config file. Let me draw up a hypothetical config file example with the logic of the dspam plugin. The syntax is sort of borrowed from Exim :) ----begin folder action config---- copy into "SPAM" fail condition !${defined:header:X-DSpam-Signature} fail message "Message doesn't have dspam signature!" run "dspam --signature ${header:X-DSpam-Signature} --is-spam" copy outof "SPAM" ignore to "Trash" fail condition !${defined:header:X-DSpam-Signature} fail message "Message doesn't have dspam signature!" run "dspam --signature ${header:X-DSpam-Signature} --not-spam" ----end folder action config---- I'm sure others can come up with examples where the config file has to be even more elaborate... I can imagine having a 'pipe' action instead of 'run' that would give the command the message on stdin for example. johannes

[Dovecot] VERY cool add-on request.
by Adam M. Dunn 20 Mar '06

20 Mar '06

I would like to have the ability to execute a command on a folder based on a user doing something like copying a message to that folder. This could be accomplished with a config file directive. For example, this would be EXTREMEMLY useful as a spam learning hook. Take a scenario where each user has their own spamassassin bayes database, and you want to give the users the ability to train their own database based on what they think is SPAM. It would be nice to give all the users a folder called Spam, and tell them to just copy/move mail into that folder, and spamassassin will automatically learn about it. If we had a configuration hook where you could execute on a copy/move, then I could tell Dovecot whenever a user puts a message into the Spam folder, execute 'sa-learn --spam --file %s' on that message. Sure we could just do an external script in a cron job to do it every hour or something, which I'll probably do in the mean time, but often users will just delete messsages after they copy into it. Doing it through IMAP means spamassassin will learn about it immediately. How cool would that be? It seems like an easy hook to implement. I would like to patch it myself for my own use, but I'm not very proficient in C. I saw someone on the net patched Courier to do the same thing so I know I'm not alone in wanting this. Anyone know how I could patch it? Can we add that to the feature request list? ~Adam

Give me more hints and I will add a new wiki page. The feedback the command gives is $ ./convert-tool Fatal: Usage: <username> <home dir> <source mail env> <dest mail env> Why does the tool want a home directory? What does it look for there? I know you say the syntax is the same for other tools but I don't know it for them yet either. :-) Guessing at the syntax for the source, it looks like the first thing is the format of the source (mbox:) followed by a directory containing mbox format files. The INBOX portion specifies the location of the mbox that the MDA puts incoming messages into. I can see the variables defined in doc/variables.txt, got that already. Is it intended to run both directions? That is, if I swap the last two args is will it convert maildirs into mboxes? This comment from Stian seemed pertinent as well. > But there is at least one "bug" with this; you should convert .'s in > mbox names to underscore or something, else it looks weird. Other than > that, it seems to work fine :) ..but I am unsure what 'looks weird' means. Can you give an example? Why is this tool under 'plugins' when it appears to be a separate utility?

So, line "shadow ... invalid password field" is OK (when I made a local password in shadow the login was success) My dovecot.conf looks like: sl_disable = yes protocol imap { listen = *:12143 } auth_default_realm = FZU.CZ auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } original /etc/pam.d/dovecot I introdused by lines auth sufficient pam_krb5.so auth required pam_unix2.so use_first_pass nullok or tryed to substitute whole file pam.d/dovecot by actualy working one of imap: #%PAM-1.0 auth sufficient pam_krb5.so auth required pam_unix2.so use_first_pass nullok auth required pam_unix2.so account required pam_unix2.so but similary fruitless. Which direction I have to dig? P.S. Dovecot was built from dovecot-1.0.beta3-6.src.rpm on SuSE 9.0 with the same result like from dovecot-1.0.beta3.tar.bz2 :(

by Netlink Tech 17 Mar '06

17 Mar '06

Hello, I have a FC4 x64 server that I am configuring/testing. It had dovecot 0.99 loaded after I did a yum update. That worked great with mbox, the passwd file, and test users in /home/users/username. I would like to be able to authenticate virtual users by 'username(a)domain.com' and have them be able to use squirrelmail or Outlook/Outlook Express to access their email. Users have no reason to have a login (shell) account on this machine. I also would like to use the maildir format for performance. I also have hundreds of users currently on a RH9 mail server using qpopper in mbox format, hashed mail spool. Questions: 1)Is a mysql database the best way to support "user(a)domain.com" email users? (they don't have any reason for a shell account on this machine) 2)What version of dovecot should I be using? I prefer RPMs and at http://www.dovecot.org/list/dovecot/2006-February/011467.html I found http://fedora.ivazquez.net/yum/4/x86_64/RPMS.alternatives/dovecot-1.0-0.iva… I installed this and then configured procmail for maildir delivery. I configured dovecot-sql.conf for mysql driver...but the mysql driver does not appear to be compiled in this rpm. 3)Anyone have any general tips on how to configure such a beast? Thanks, Curt

Thanks, Dovecot seems to create a lot because of the indexes, but they dissapear with the cron. -Bert >From: Jeff Ballard <ballard(a)engr.wisc.edu> > > >There should be a cron job on the server that deletes those > >>From /var/spool/cron/crontabs/root: > >15 3 * * 0 /usr/lib/fs/nfs/nfsfind > >Looking at /usr/lib/fs/nfs/nfsfind: ># less /usr/lib/fs/nfs/nfsfind >#!/bin/sh ># Copyright (c) 1993 by Sun Microsystems, Inc. > >#ident "@(#)nfsfind.sh 1.7 00/07/17 SMI" ># ># Check shared NFS filesystems for .nfs* files that ># are more than a week old. ># ># These files are created by NFS clients when an open file ># is removed.

[Dovecot] virtual users
by tblader 16 Mar '06

16 Mar '06

Hello All. I've been reading the virtual user howto but cant get the login working. dovecot.conf is below [0] if anyone can offer some pointers. I'm confused about the format of /etc/imap.passwd [1] also. Does the "pass" word in the example need to be plaintext, or the MD5 string from do. Also, what is the significance of "{plain}"? If there are docs I've missed, please RTFM with a link. Thanks [0] - dovecot.conf ----------------------------------- protocols = imap imaps mail_debug = no protocol imap { } protocol pop3 { } auth_verbose = no auth_debug = no auth_debug_passwords = no auth default { mechanisms = plain passdb passwd-file { args = /etc/imap.passwd } userdb passwd { } userdb passwd-file { args = /etc/imap.passwd } user = root } plugin { } [1] ------------------------ testuser:{plain}pass:65500:65500::/var/spool/mail/testuser

It's my server and it's still running and working properly. Dovecot version is (as on the newer server) beta3, but the first Dovecot running was beta2 I think. Imap works properly on that server. Anyway Dovecot shouldn't crash ever if the index files are broken!

[Dovecot] Shared Folders Problem. Bug?
by Adam M. Dunn 16 Mar '06

16 Mar '06

I'm trying to get shared folders to work, and I've noticed a few issues. I created a private and public namespace, the private one with autodetection for Maildir or Mbox, and the public one for a public folder. Something like this: namespace private { separator = / inbox = yes prefix = location = } namespace public { separator = / prefix = Public/ location = maildir:/var/mail/public } My plan is to eventually setup a public area for users to drop Spam and Ham into for my spam bayesan filter. The problem is the Wiki says if you drop a file in the public area called 'dovecot-shared' with the same permissions and ownership, that any new files dovecot creates there will use those same attributes. This does not seem to be the case. I created a Maildir folder identical to the one on the Wiki, named everything 'dovecot:dovecot' since my dovecot server will be running as that user, as well as the 'dovecot-shared' file. I get permission denied errors in syslog when I try to access it via an IMAP client. The only way I can make it work is ignore the dovecot-share file and put all users in a common unix group and make the Public folder group 'rwx'. Also, I would like to be able to make the Public folder writable, but not readable. It seems if I take the read bit away, my IMAP clients complain. Does anyone know how to make that work? One thing about the namespaces while I'm at it. I had to put my private namespace first followed by the public one. If I reversed them, all the subfolders except the inbox in my mail directories disappear from the client. Is that a bug too? Thanks, Adam

[Dovecot] Problems with Oulook Clients
by Patrick Carney 16 Mar '06

16 Mar '06

Hello all. I have problems with clients running Outlook 2003 that keep getting IMAP server timeout errors, "mailbox in an inconsistant state" Are there any mods to be made to the config file that could eliminate this? It happens about ever 10minutes. Here is what our previous Sys Admin sent me on our setup. dovecot is the IMAP server that allows clients to connect and get to their mailboxes. Postfix is that part of the mail system that moves messages around, from one server to another and puts them in the appropriate mailboxes. Thanks Patrick

[Dovecot] migrating POP3 from UW IMAP: X-UIDL and X-UID
by Bertrand Leboeuf 15 Mar '06

15 Mar '06

With a INBOX mbox created by UW IMAP the messages in INBOX mbox contains the X-UIDL field When I use Dovecot POP3 with pop3_uidl_format = %08Xv%08Xu on the first run, X-UID is inserted, but all messages are downloaded again. What am I missing, I don't want the clients to download the read messages again. Thanks Bertrand Leboeuf leboeuf(a)emt.inrs.ca

[Dovecot] Imap crashes when trying to move messages

15 Mar '06

The imap process crashes when SquirrelMail wants to move a message to another folder. I have run imap in gdb and talked to it the same way SquirrelMail does and got a backtrace. I am using Dovecot beta3. I am using it in combination with XMail, which has maildir databases. My system is Gentoo Linux on x86. The same version of Dovecot works great for me on amd64 with exactly the same config.

[Dovecot] Strange dovecot-uidlist behavior on maildir conversion
by allen petersen 15 Mar '06

15 Mar '06

Hi. So I just moved my email over from mbox to maildir. For the most part the conversion went fine, but I had a bit of an odd thing happen when I accessed my mail through dovecot. It seems that when I ran mb2md to convert my mailboxes from mbox to maildir, I got a lot of messages created that look like 1142356176.000000.mbox:2,RS 1142356176.000421.mbox:2,S 1142356176.000001.mbox:2,S 1142356176.000422.mbox:2,RS 1142356176.000002.mbox:2,RS 1142356176.000423.mbox:2,S 1142356176.000003.mbox:2,RS 1142356176.000424.mbox:2,S and so forth. Now, that really should be fine, that I can tell; each message has the same timestamp and a different, sequential delivery identifier. However, for some reason when dovecot accessed this directory, it created UIDs for these messages like so: (from dovecot-uidlist) 1 1142362834 915 1 1142356176.000488.mbox 2 1142356176.000207.mbox 3 1142356176.000425.mbox 4 1142356176.000117.mbox 5 1142356176.000398.mbox 6 1142356176.000335.mbox I have no idea where this order came from, but it's clearly not the order that I would have expected. I would expect that dovecot would sort these messages by timestamp, followed by delivery identifier. Instead, it put them in a seemingly random order. And, of course, my email client by default shows messages in the order that it gets them from the server, so now when I look at my email all of my old messages are shuffled until I do an explicit sort by date. Any idea why this is happening? Is there some reasoning behind this, or is it just a bug? I looked through the archives a bit, but didn't find a mention of anyone else with this particular problem. I suppose I could just create the initial uid lists by hand and put them in the correct order, but that really doesn't seem like the correct solution. Or I could actually dig through the source and find out exactly what it's doing, but, well, I figure that asking the list first is easier. For reference, I'm running dovecot 0.99.14-1 on debian sarge. I though that I was doing a good job by reproducing this on the newer version my ubuntu desktop, but it turns out that it's running the same version. :) -allen

[Dovecot] Rootless configuration
by James Davis 14 Mar '06

14 Mar '06

I'm trying to setup a rootless configuration so I can better manage the e-mail that comes to the mailbox of a unix account I have. I've successfully compiled Dovecot and followed the instructions for a rootless configuration, tweaking my config until Dovecot returns no errors. However I've got to a stage where upon running ~/..../sbin/dovecot it just quits with no server running and no errors. Any ideas? My rather small and basic configuration file is as follows... # Base directory where to store runtime data. base_dir = /home/jamesd/imap/dovecot/run/ # Protocols we want to be serving: protocols = imap listen = * ssl_disable = yes log_path = /home/jamesd/imap/dovecot/logs/ info_log_path = /home/jamesd/imap/dovecot/logs/ ## Login processes login_dir = /home/jamesd/imap/dovecot/run/login login_chroot = no login_user = jamesd ## IMAP specific settings protocol imap { listen = *:10143 } ## Authentication processes auth default { mechanisms = plain passdb passwd-file { args = /home/jamesd/imap/dovecot/etc/passwd } user = jamesd } Many thanks, James -- http://www.freecharity.org.uk/ - Free hosting for charities http://jamesd.ukgeeks.co.uk/

[Dovecot] Shared maildir through namespace help...
by Brice Figureau 14 Mar '06

14 Mar '06

Hi, I'm a happy user of dovecot since the 0.99.x days, and recently switched my user base to 1.0b2. Now, to the point, I got a request (from marketing) to share a lot of maildirs between two (and possibly more) accounts. Those two accounts have differents uid/gid. The maildirs are actually in one of the account. I thought I could possibly craft a public namespace for those maildirs as explained in the wiki, but alas, it doesn't quite work as I expected: excerpt of dovecot.conf: namespace public { separator = / prefix = marketing/ location = maildir:/home/marketing/Maildir:INDEX=%h/ } users belong to the marketing group. $ find /home/marketing/Maildir -ls 4767751 4 drwxrwxr-x 3 marketing marketing 4096 Mar 14 11:57 . 4767752 4 drwxrwsr-x 6 marketing marketing 4096 Mar 14 11:59 ./Maildir 4767753 4 drwxrwsr-x 2 marketing marketing 4096 Mar 14 11:57 ./Maildir/cur 4767754 4 drwxrwsr-x 2 marketing marketing 4096 Mar 14 11:57 ./Maildir/tmp 4767755 4 drwxrwsr-x 2 marketing marketing 4096 Mar 14 11:57 ./Maildir/new 4767756 0 -rw-r--r-- 1 marketing marketing 0 Mar 14 11:57 ./Maildir/dovecot-shared >From there, the namespace is visible from all the IMAP accounts.

The result is that any other user don't have access to this directory even if it is in a public namespace. Now, the question, is: is that setup could work only with virtual users setup with a static uid/gid ? Is there a mean to implement what I want ? Does using symlinks instead of the namespace could work ? Regards, -- Brice Figureau <brice+dovecot(a)daysofwonder.com>

[Dovecot] mbox to maildir conversion - good idea regarding Outlook?
by Gerhard Hofmann 14 Mar '06

14 Mar '06

Hi list, first of all, many thanks to the Dovecot authors for supplying an IMAP server that works well with M$-Outlook! I have used UW-imapd for quite a while and was annoyed by frequent "imap...timeout..." error messages. Now I'd like to give maildir format a try because I want to use email sub-folders. What are other Outlook users' experiences with maildir? Is it as stable as mbox? Regards Gerhard

[Dovecot] tls
by lenny＠edpausa.com 13 Mar '06

13 Mar '06

is it possible to turn off TLS and only SSL ? The reason are many reasons for this, one major being the fact that TLS is automatically discovered by many clients on the standard ports, thus requiring a valid cert for production use, while SSL could be set up on some unknown to anybody port with self signed cert for testing, etc... thank you

Hello, we have problems to access our users mailboxes with SquirrelMail. The log file /var/log/mail.log says permission denied, only one user is allowed to read his mail with SquirrelMail. We are running Debian Sarge, Mailserver is Postfix, imap server is dovecot. Our Mailboxes are stored in the mbox format. Folder of the mbox files is /var/mail/ the users are unix system accounts. Normally we read are mail with the POP-Client Outlook, this works well. But we also want to be able to read our mail (each user his own mails) via SquirrelMail /var/log/mail.log says: Mar 13 10:54:40 webserver dovecot: imap(unix-system-account): mkdir_parents(/var/mail/.imap/INBOX) failed: Permission denied In the folder where the mbox files are stored exists 3 folders called INBOX.drafts INBOX.sent INBOX.trash These folders are owned by the user who is able to read his mail via SquirrelMail and owned by the group mail. Only the user has read and write permissions. Does each user need to have his own INBOX Files? Could you please help me Kind regards, Roland

[Dovecot] Limiting Dovecot access by user-spesific ip addresses?
by Timo Neuvonen 13 Mar '06

13 Mar '06

Hi, Is there any possibility to limit access to mailboxes by user-spesific ip addresses? So, I'd like to have a configuration which by default restricts reading emails to company's own ip-address range. So far, this could be achieved by a basic firewall rule, but not any more the following: However, there is need for a few users to access their emails from world-wide internet, so there should be a possibility to define for certain users an option to skip the allowed address range check.

[Dovecot] Suggested patch: retain user's group privileges after logging into IMAP
by Lior Okman 11 Mar '06

11 Mar '06

Hi, I'm attaching a suggested patch that lets an authenticated user access shared IMAP folders even if the user doesn't directly own the storage, but is a part of a group that has permissions on the storage. This allows for the administrator to setup a shared mailbox with permissions given to a group instead of a user, and allow all of the users that belong to the group to access the mail according to the file-system permissions. What do you think? Is this the right way to do this, or am I missing something security-wise? I'm also attaching a bug fix for the LDAP passdb, where if the password scheme wasn't PLAIN, the password would be cleared from memory before being used to authenticate the user, and the authentication would fail. Regards, Lior

[Dovecot] Segfault problem when using TWO dovecot servers!
by Adam M. Dunn 10 Mar '06

10 Mar '06

Forgive me if this gets submitted twice. I had issues signing up for the listserv but I think I'm strait now. Hi all, I just started working with Dovecot and I'd like to use it for my organization, but I've run into a little problem. So far I love it and it does what I need. One thing we need is to be able to write to multiple mailbox formats on a per user basis (mbox or Maildir), and it does just that. I want users to be able to choose their format, and I can let it autodetect for me. The way I do that is I have Maildrop filters check for the presence of a ~Maildir, and if it finds that it writes to it, otherwise it writes to ~mbox. Dovecot is the only IMAP server I've found to read either or without hard coding one or the other in the config file. The problem: We also want failover. Mail/home directories are NFS mounted. I was planning to setup two dovecot servers, and noticed that whenever one server writes its temp files to the mail directory, if another server tries to read it you get a segfault and the child process fails and dies. So it basically looks like only one server can own the files, and it won't share. I considered trying to set the INDEX option on the mail boxes to write local indexes, but if I try to specify something like: default_mail_env = INDEX=/var/indexes/%d/%n, it doesn't work. Sure I can make it work by putting in a mailbox format before the INDEX, but then I can't use the autodetect which I need. Here's the syslog error: kernel: imap[13689]: segfault at 00007fffffe38000 rip 00002aaaaad3823f rsp 00007fffffe351f0 error 4 Any solutions? I really need this to work badly, or we may have to rethink our entire mail strategy. I'm also using the latest version 1.0beta3. I considered namespaces, but correct me if I'm wrong, you can't setup two namespaces and have it pick the first mailbox format available like the autodetect feature does. I tried seting up namespaces for both mbox and Maildir, but it just creates both. Please help someone. I need a solution to present to my boss, even if that means we have to run one server until the bug is fixed in the next version. Thanks, Adam

[Dovecot] POP3 extension to accept UIDL ranges?
by Matthias Andree 10 Mar '06

10 Mar '06

Greetings, is anybody aware of an extension to POP3 that supports UIDL ranges? It would be very useful for keep-messages-on-server setups (yes, I know, IMAP4 domain) to be able to do UIDL 21-42 to obtain just these 22 UIDs (this would always have to be a multi-line reply, just like UIDL without argument). If such a thing does not exist yet, perhaps a keyword such as "[X]UIDLRANGES" in the CAPA response might advertise this feature to clients. Regards, -- Matthias Andree

[Dovecot] Two namespaces with same prefix.
by Václav Haisman 09 Mar '06

09 Mar '06

Hi, I have yet another problem. First let me explain my setup. I used to use pine a lot so there are mbox mailboxes in ~/mail. Recently I added a Maildir too and moved most of the mbox mailboxes into Maildir format. Now I thoght it would be nice to have them all "in line" in Thunderbird so I tried this configuration: namespace private { separator = / prefix = location = %h/mbox inbox = yes } namespace private { separator = / prefix = location = maildir:%h/Maildir } The problem is that with this configuration I cannot access the ~/mail/box mailboxes. Thunderbird responds with "Mailbox doesn't exist: box" Is such kind of configuration with two namespaces having same prefix unsupported? Vaclav Haisman

[Dovecot] Default SELinux policy on Fedora FC4 prevents dovecot service from starting
by slohcine＠verizon.net 09 Mar '06

09 Mar '06

Hello, I recently setup a Fedora FC4 server to host e-mail and webapps. During the install, I turned on SELinux in active mode. All apps seems to work OK but Dovecot daemon won't start. In the audit log, I see this entry when I try to start the dovecot daemon. type=AVC msg=audit(1141464818.541:40305): avc: denied { read } for pid=1989 comm="dovecot" name=dovecot.pem dev=md2 ino=3646976 scontext=system_u:system_r:dovecot_t tcontext=system_u:object_r:cert_t tclass=file type=PATH msg=audit(1141499436.214:3266533): item=0 name="/etc/pki/dovecot/dovecot.pem" inode=3646976 dev=09:02 mode=0100600 ouid=0 ogid=0 rdev=00:00 I put SELinux into permissive mode and Dovecot works OK. Looks like dovecot does not assume the correct security context when it initializes and reads the cert file. My question for the list is what changes should I make to the SELinux policy to safely permit dovecot to read the file? I'm no expert at SELinux but hoping for some direction, or another way to solve this problem. Ideally, I'd like to keep SELinux in enforcing mode. Many thanks, Eric

[Dovecot] MySQL problem when using Dovecot as proxy
by Christian Jensen 09 Mar '06

09 Mar '06

Hi, I have just installed Dovecot as a POP3 proxy with great success. Its works flawlessly when i keep to the standard but since I am proxying a Microsoft Exchange 2003 (because the build-in POP3 in MS sux bigtime) I would very much like to use account names like: DOMAIN\username and this doesn't work when I include that in the MySQL table. In the logfile it clearly writes DOMAIN\username so its some kind of translation between dovecot and MYSQL. Any suggestions. I another solution would be to allow all users instead of having to create them in the MySQL table. Is this possible ? /Christian P.S Before Dovecot some Outlook users could only download max. 250kB through POP3 - now with Dovecot there is NO LIMIT! :)

[Dovecot] Can I install in the following fashion?
by Stewart Dean 08 Mar '06

08 Mar '06

<permit me my perhaps foolish preference...an explanation> I run mail service for a small college. I've long joked that if someone stole the mail server, the phone would ring before the alarm (which has a 1 minute delay) did, that the user base expected 25x8x367 coverage. Making updates/upgrades to the mail server feels like a tightrope walk with no net. I always appreciated UofWIMAP because there is one binary. Doing and upgrade or backing it out is simplicity itself. I could compile the single binary on my compile machine, test the same binary on my testbed, and then drop it in my production machine and it would work with a minimum of surprises. So portable, so predictable, no security risk of a compiler on a production machine. Of course, /most/ of open source software has all these bits and pieces scattered everywhere. Oh, it may install initially just dandy, but come the day when It's Time For The Upgrade.... 1) can I do it quick and clean and 2) can I recover to what I had before quickly and correctly if the upgrade flops?????? Alas, Dovecot is sprinkled in many, many pieces...but at least, I think (right?) that they are all in the prefix-dir. Gulp. So. I am hoping I can do this: Build/Test Install 1) build/install in /usr/local/dovecot_bld/ Build### in the expectation that everything will be stuck down there. I don't want to put it into /usr/local/ because it will be in there with everything else....no way to get just the dovecot stuff.. 2) tar up the contents of my prefix directory and extract it over on my testbed under /usr/local/dovecot. Notice that the path to dovecot's "stuff" has changed from /usr/local/dovecot_bld/ Build### to /usr/local/dovecot I'm hoping that this won't be a problem. I will point the line in inetd at it and Everything Will Work. 3) Assuming I don't change anything and everything tests out (flawlessly!), I............. Introduction to Production (assuming that all the mailboxes, homedirs and the like have been sorted out) 1) make a tarball of the current working dovecot executables dir (/usr/local/dovecot) 2) extract the tarball there as before on the testbed machine and everything is fine. 2) if the update flops, I can bring back the tarball of the previous Dovecot incarnation My Questions: A) Will this work or are there dependencies I'm not aware of? B) Is there Some Better Way or..... I have this ongoing <ahem> discussion with the Open Source wonks that delight in many, many modules, libraries, etc. I /know/ the reasons a developer would want to do things that way, but, for those of use fielding the application, it's /so/ much easier and success/failure recovery is /so/ much more likely if....there are only one or two or three chunks that we can drop in or quickly back out. I realize that the developer is coding in large part for the utter joy of creating a wondrous, living, breathing edifice of code, that works, that works cleanly, that works as none has before. Yes. But I would think (IMHO) that the developer would receive a greater portion of the ego rush (also a big part of the developer stimulus) of overwhelming application acceptance (and thunderous applause), if he or she made it easy to support and upgrade! You see a sysadmin is so often an utter coward (I confess), who doesn't like unpleasant surprises, whose managment Really Doesn't Like Unpleasant Surprises. When I do my job really well, nobody knows I've done anything. OK...let me have it. -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Busy studying
by Timo Sirainen 08 Mar '06

08 Mar '06

In case you're wondering why I haven't answered your mail. I try to do as much reading to exams as possible, and as little as possible anything else.. They're over in 2,5 weeks, so I'll start reading the old emails again then. :) BTW. If someone wants to help a bit, outlook-idle workaround seems to be broken. The timeout function never gets called in cmd-idle.c. I'm guessing it broke after I added the other timeout function for printing "OK Still here" message every 2 minutes, so the bug is probably in timeout handling in ioloop.c.

[Dovecot] Simple Question

Brand spanking new to Dovecot. Trying to move over to it, got a few simple questions. 1) Is there any documentation on the .customflags file? Not sure what this is for... 2) I'd like to make a directory for every user NOT be writable. Meaning the email server (Exim) can put the mail down in the directory but a user can no move an email into it through Imap. I couldn't find a search for the mailing list either, so sorry if this has been asked 92380498 times. -Charlie

Hi, would it be possible not to treat ~/mail specially and not to add mailboxes in the directory automatically? It would make migrating from IMAP-UW easier. Vaclav Haisman

[Dovecot] Undeleteable folders
by Casey Allen Shobe 08 Mar '06

08 Mar '06

We have 3 folders in every user's account which need to be there. Sometimes the users are stupid and delete or rename them. Is there any way to make them unmodifiable, but still allow them to see them, and move mail into/out of them?

[Dovecot] Dovecot with mbox and maildir
by Dario Ale 08 Mar '06

08 Mar '06

Hello, I have a question, i need migrate from old mail server to new mail server, the mailboxes format in the new mail server is maildir, in the old is mbox, the problem is that only the INBOXs are approximately 64Gb (are 7000 users), in the new I installed Dovecot, in the old is UW-Imap. The question is, Is there any form for have mbox and maildir simultaneously with Dovecot? I am using Postfix, my MDA is procmail, this write mailbox in the correct format, then i can copy all INBOXs and HOMEs to the new mail server, and change the mailbox format "slowly", supposedly procmail detecting the mailbox format and Dovecot could detect too. Thanks, very much. pd: sorry, my english not is good. -- Dario Ale (dario.a en telpin.com.ar) Area Internet Telpin - Jason 1026 - Pinamar (7167) www.telpin.com.ar

[Dovecot] self-signed certificates
by Benjamin 08 Mar '06

08 Mar '06

Hallo, i'm having troubles installing self-signed certificates for dovecot. After installing, dovecot generates a key and cert. But he is using the wrong common name (where does dovecot get this name from?). I tried deleting them and installing a handcrafted cert with this: openssl genrsa -out mail.key 2048 openssl req -new -key mail.key -out mail.csr openssl x509 -req -days 4312 -in mail.csr -out mail.cert -signkey mail.key after that i tried to update the dovecont.conf to point to the new files. But dovecot refuses to read them, i allways get an error, that dovecot can't read the certificate file. With dpkg-reconfigure dovecot-common, dovecot generates new ones, and they are working fine, but have the wrong common name. Thanks in advance Regards Benjamin

Will that be a problem? I'm not sure, but I think this setting is used for compile time - it's where dovecot expects to find include files, it doesn't mean that anything will be installed there. If you're really concerned, then use "make -n install", and go over the commands that make would have run, you will be able to see exactly where everything goes. Or you could run "make install" inside a chroot jail. I also seem to recall that I saw a script somewhere that could trace the "make install" procedure and print exactly where it puts everything. It was being used for converting .tar.gz "make-based-installations" to rpms. > Q2: Will dovecot not be able to find system resources it needs? Dovecot should be able to find everything it needs, assuming the configuration files are ok. > Tar'ing up a directory is doable. RPM'ing hundreds of files scattered > here and there, perhaps referenced by others, perhaps with new > additions/deletions you don't know about sounds like an heroic task. Tar`ing a directory is doable, but doesn't lend itself well to reusing components and sane system management. When you use RPM/DPKG for manging your configuration, each package you install is responsible for its own files and nothing more. The packaging system makes sure that nothing conflicts or overwrites existing files. If you accidently untar a file with bad configuration files in it, they will probably overwrite your existing configuration. RPM/DPKG will save your old configuration files. Tar can't help you verify that what you installed is what is actually running. RPM -verify can make sure that no trojan has been installed instead of a file provided in an RPM file. And the list goes on and on. > Does anybody see how simple it is to upgrade UWImap with its one binary? Just as long as there is only one binary. AFAIK, UWImap doesn't support configuration files, on the assumption that the sysadmin probably doesn't know enough to create a valid configuration. The downshot of that is that there is a limit to what you can do with UWImap's one binary :-) Lior > > Lior Okman wrote: > > Looking at the debianized version, the bulk of the files are placed in > > € > > or under /usr/lib/dovecot, with all of the configuration files in > > € > > /etc/dovecot, and relevant binaries under /usr/bin and /usr/sbin. > > € > > > > € > > However, reading from the comment in the begining of the default > > € > > dovecot.conf file, you can probably compile your own version of > > € > > dovecot where you specify the following parameters to configure: > > € > > "--prefix=/usr --sysconfdir=/etc --localstatedir=/var > > € > > --with-ssldir=/etc/ssl". > > € > > Just make sure to replace all the paths with where you want to install > > € > > this version of dovecot. > > € > > > > € > > Lior > > € > > > > € > > On 3/7/06, Stewart Dean <sdean(a)bard.edu> wrote: > > € > > > >> Hmmm, hadn't thought of RPM.

[Dovecot] dspam plugin mailing list?
by Johannes Berg 07 Mar '06

07 Mar '06

Hi, Every once a while I get mail about my dspam plugin. While that's great (tells me people are using it or at least like the idea), sometimes I think the discussions then should be accessible to others. I'm thinking of setting up a new mailing list for it so answers get archived, are searchable, and I don't necessarily have to reply to everything. I'm not sure if that's feasible though, there probably aren't *that* many users, and sometimes the questions are more dovecot questions. Would anyone on this list (esp. Timo of course) mind if I were to note on the plugin page that discussion and questions should be sent to this (the dovecot) mailing list? I'll still be reading here and answering questions, of course, but then if something crops up that's more dovecot than plugin related it's at the right place already, or if I'm off for a few days and someone else knows the answer... If there are any objections I'll just set up a private mailing list instead and ask anyone interested to join (it'd be very low volume I guess) :) johannes

[Dovecot] mbox sync: UID inserted in the middle of mailbox...
by Simon Bowden 07 Mar '06

07 Mar '06

Hi, We're getting a lot of errors like this: Mar 7 10:02:35 imapserver dovecot: imap(user1): mbox sync: UID inserted in the middle of mailbox /home/user1/mail/mail/INBOX.Trash (8 > 2, seq=2,idx_msgs=6) We have several hundred people using the server, and at least 22 have had this error in the past 24 hours. The numbers at the end change between each user, which I guess you'd expect. I was able to make the errors go away for one user by removing the index files (rm -rf ~/mail/.imap/INBOX), so I'm guessing they were corrupt. However, the problem with this is that: 1) It requires user intervention 2) The symptom is that they aren't seeing any new mail in the affected mailbox. I had thought that the indexing stuff would not *give up*, but would reindex a directory if there was a problem. Anyone able to help? Some info on our setup: /home/user is nfs-mounted. We allow them to configure their mbox/maildir type and location, but obviously this is only relating to mbox ones. Here's the config file, stripped of comments and blank lines: ==================== protocols = imap imaps ssl_cert_file = /etc/ssl/certs/imapd.cert ssl_key_file = /etc/ssl/private/imapd.pem ssl_ca_file = /etc/ssl/certs/cacert.pem log_timestamp = "%Y-%m-%d %H:%M:%S " login_processes_count = 6 first_valid_uid = 40 mail_extra_groups = default_mail_env = mbox:~/mail/:INBOX=~/.incoming-mail mmap_disable = yes mail_drop_priv_before_exec = yes protocol imap { mail_executable = /usr/local/mail/imap-wrapper imap_client_workarounds = outlook-idle delay-newmail tb-extra-mailbox-sep } protocol pop3 { } auth default { mechanisms = plain gssapi passdb pam { args = session=yes * } userdb passwd { } user = root } plugin { } ==================== /usr/local/mail/imap-wrapper is just a script that lets them configure the setup a bit (effectively change value of MAIL, and some namespace stuff), ultimately running /usr/lib/dovecot/imap. The nfs mount options on the home directory mount are: rw,hard,intr,rsize=8192,wsize=8192,nosuid,nodev,vers=3,proto=udp Thanks! Cheers, - Simon

[Dovecot] Dovecot as a smart IMAP proxy
by Timo Sirainen 07 Mar '06

07 Mar '06

Do you see a use for an IMAP proxy where the proxy would be able to execute hooks which modify mail contents, such as transparent encrypting/decrypting mails, or maybe some virus-filtering? It would need at least some kind of IMAP command/reply parsing capabilities, so it might be able to do all kinds of other things. Maybe one potential use case would be Cyrus Murder-like proxying to multiple IMAP servers to distribute the mailboxes. But that might be done better as an imap process plugin, or maybe as IMAP mail storage backend. Anyway, the reason I'm asking this is because I was asked to add mail encryption/decryption capabilities to Dovecot's IMAP proxy, but I'm not sure what would be the best way to handle this. In any case it would be a plugin or a new binary which is executed instead of imap binary, but can I do it in a way that would actually be useful for Dovecot project in general?

[Dovecot] [IMAP] Strange! No problem when I import mails from local to server.
by Xueron Nee 07 Mar '06

Hi, All: I hava just post a question that says when I move mail from one folder to another, mails were holded in the tmp directory of the target folder. I try to move mails from server to local and then, move them from the local folder to the server side folder, it works fine :) I refresh the tmp directory and could see tmp files created-unlinked, and all mail imported to the target folder currectly. What's the problem when I move mails between server-side folders? -- Xueron Nee <xueron(a)gmail.com>

[Dovecot] [IMAP] mails holded in tmp directory
by Xueron Nee 07 Mar '06

Version: 1.0.beta3 OS: Redhat AS 4 I use the cvs version of Dovecot to run my IMAP server. When I move some mails from one folder to another, only 1 or 2 mails are moved, while others were holded in the tmp directory of the target folder. So, what's the matter? I use becky and Outlook as client, and both of the two have the same problem. Thanks :) -- Xueron Nee <xueron(a)gmail.com>

[Dovecot] Shared Folders (1.0beta3)
by Timothy White 07 Mar '06

07 Mar '06

A few quick questions, as documentation seems to be sparse. * Is there a way to force a shared folder to be subscribed to? If I am using SquirrelMail I have a plugin to do that, but not if they are using another IMAP client. * Are there some sort of ACL's on shared folders, so that I can (hopefully with a sql backend), allow different users different permissions on the folder? * Is it a bug that we can't subscribe to the shared folder, only to it's sub folders? (and is there a way to work around this, i.e. if the shared folder isn't really a Maildir, but it's sub folders are? Other than that, so far, my glimpse at 1.0beta3 is looking very good, and came at the right time, as I was thinking I might need to use Cyrus for the project I'm working on atm... Thanks Tim -- Linux Counter user #273956

I'm trying to set up a PHP application Ingo (part of Horde suite) to create the file <home>/.dovecot.sieve for the "advanced" LDA to do mail sorting. Because PHP is running under a Web server user, Ingo can't really write this file directly. My question is, is there any way for Ingo (or any other tool, for that matter) to create that file via IMAP protocol interaction? Horde authenticates users and "knows" login/password combination (that's how it accesses mail folders). Thank you! Sergey.

[Dovecot] Really dumb question
by Al Blake 05 Mar '06

05 Mar '06

Just got dovecot running inside MEPIS 3.3.2 SOHO (debian). I am impressed. It works really well and I am planning to move my mail away from my Win server and access the mail from dovecot using imap. I have copied some folders from my existing Outlook mail system into the imap mail server without any problems....so here is the dumb question: where are the mail files/folders stored on the MEPIS server? I have been all over the file system and cant find any files that look right. The dovecot doco talks about mail location for the index files - but I have looked in all of those and cant find anything. The MEPIS system has a Maildir for the user......but that looks just as it did at install: contains three folders, cur, new and tmp all of which are empty :( Please dont flame - I have looked and I did try to find the answer but I although I can see the folders and messages through the imap client I cant actually find anything on the server.......and I would like to see something before I turn my Win mail server off.

[Dovecot] Apple Mail cannot connect (1.0 beta3)
by Gregory K. Ruiz-Ade 03 Mar '06

03 Mar '06

I'm testing 1.0 beta3 on our mail server, and finding that Apple Mail seems unable to connect to it. I'm running the 1.0b3 on port 997 so we can test it in parallel to 0.91 to compare performance (so far, it's hella faster). I've ensured that the users testing are _not_ connecting in any way to the 0.91 version running on port 993. From the OS X client side (10.4.5 + latest patches), Apple Mail simply sits there and spins, and eventually times out. The error it gives is: ----- Alert There may be a problem with the mail server or network. Check the settings for account "UCSD" or try again. The server error encountered was: The connection to the server "csefast.ucsd.edu" on port 0 timed out. ----- I'm thinking, "port 0, WTF?" ... On the server, I get this out of the logs: ----- Mar 2 11:54:48 csefast dovecot: imap-login: Disconnected: Inactivity: rip=<client_ip_address>, lip=<server_ip_address>, TLS Mar 2 11:54:48 csefast dovecot: imap-login: SSL_accept() syscall failed: EOF [<client_ip_address>] ----- Apple Mail is configured to connect to port 997 and has "Use SSL" checked. I'm not getting anything else useful out of the Mac in terms of debugging info. Thunderbird seems to be working fine (all platforms).

[Dovecot] Thunderbird 1.5 and dovecot 1.0 beta 3 problem
by Peterg 03 Mar '06

03 Mar '06

My mailhosting provider has been testing dovecot 1.0 beta 3 as a proxy server and they asked the customers if they would like to test it out and report any issues. I am using Thunderbird 1.5 (IMAP) and have been with this mailhosting company for two months and have no issues at all with their current setup which uses Perdition as their proxy servers. The problem(s) I am encountered have been reported here a few times previously over the last couple of years but in searching I have not found any concrete solutions. When I first tested it out there was a continuous problem of a failure in saving a copy of an email to the sent folder although the message was sent. One of the staff of the mailhosting company noted this exact problem as well and believed the issue was Dovecot announcing different IMAP capabilities than the real backend IMAP servers (via the CAPABILITY command). This was supposedly fixed and initially there were no issues with the first set of test emails. However, in short order, this problem re-emerged and there would be sporadic failures to copy a message to the sent folder. Another issue would be that every now and then, when clicking on a folder in the left-hand pane (and no other activity going on with Thunderbird like downloading a new mail) Thunderbird would hourglass for 10-15 seconds as if it were trying to open a connection and was having difficulty. The maximum number of connections setup in Thunderbird is the default 5 and I am advised that this is the correct setting with their servers. Reducing the maximum number of connections does not appear to change matters in terms of avoiding these problems. Changing back to the current system (ie not using the test proxy server) both these issues disappeared. I have been in communication with the mailhosting provider as to my findings but it would be most appreciated if others here would perhaps have some insight into this matter. Peter

[Dovecot] maildir locking and 'racing'
by William Ross 02 Mar '06

02 Mar '06

hello Timo, list, quick error-message question. A few of the accounts on my main mailserver are failing to log in with errors like this: dovecot: Mar 02 19:33:35 Error: imap(user(a)example.com): maildir_file_do(/var/lib/vpopmail/domains/example.com/user/Maildir) racing if I log in by telnet everything is fine, and from the source it looks like the error happens when dovecot fails to get a lock on some important file or other. Could it be to do with concurrent connections? No idea. Has anyone seen this, and can you suggest a quick fix? I can't see any obvious difference between the accounts that work and those that don't :( nb. this is with vpopmail, and the Maildirs have just been moved over from another server that was also running the same version of dovecot. Some of the accounts do work. Perhaps it's just an obscure file permissions problem, or something? I'd be very glad of any suggestions. thank you, will

[Dovecot] Maildir Quotas

Hey guys, Does anyone have any ideas as to when this may be implemented? I'd love to be able to use dovecot, but without quota support, it just won't fit the bill. Is there any developer documentation as to what would be required to fully support maildir quotas as I'd be willing to help implement it assuming it's not going to take me weeks to become familiar enough with the codebase.

[Dovecot] using dovecot for postfix sasl

I have followed the Dovecot/Postfix/SASL howto, and modified the main.cf and dovecot.conf files, yet when trying to authenticate during a postfix SMTP session the log reports: "postfix/smtpd....warning: SASL authentication failure: Could not open db" Dovecot itself is authenticating IMAP logins correctly, and it is creating the auth file in the location specified under /var/spool/postfix/private. Why is postfix not able to get to the Dovecot auth mechanism? Thanks. Hugh

[Dovecot] Sorting order after mail move
by Václav Haisman 28 Feb '06

28 Feb '06

Hi, when I move some recent mail from some mbox folder into Maildir folder the moved email sorts as the first (on top) in the folder while it should be on the bottom with the rest of the recent emails in the folder. This happens only when moving from mbox folder to Maildir folder. I am not sure if it is really Dovecot bug or not but I suspect it could be so because it only happens in this one specific scenario.

28 Feb '06

We're currently in the process of organising a migration from mbox to maildir mail storage on our server, and are hoping to phase this in gradually using dovecot's capabilities. Procmail has already been configured to deliver mail to either the existing mbox or to a new maildir for the user based on the (non)existence of a .converted file in their home directory. Where we are having problems is the pop3 retrieval side of things. Basically, we're chasing a setup where dovecot will first check to see if /mail/<first letter of username>/username exists (indicating that the account has had the .converted file created and new mail has since been delivered to that user in the new maildir format). If this directory does not exist, it should fallback to retrieving mail from the as-yet unconverted mbox, /var/mail/username. We've tried different combinations of namespaces and default_mail_env values to achieve this without success. One attempt which has come particularly close was: 1. Leaving /etc/dovecot.conf almost entirely default. The auto-detection ability of dovecot performs the following (output to /var/log/maillog): Feb 28 14:57:45 mouse dovecot: pop3(joe): maildir: access(/home/joe/Maildir, rwx): failed: No such file or directory Feb 28 14:57:45 mouse dovecot: pop3(joe): maildir: couldn't find root dir Feb 28 14:57:45 mouse dovecot: pop3(joe): mbox: root exists (/home/joe/mail) Feb 28 14:57:45 mouse dovecot: pop3(joe): mbox: INBOX exists (/var/mail/joe) Feb 28 14:57:45 mouse dovecot: pop3(joe): mbox: root=/home/joe/mail, index=/home/joe/mail, inbox=/var/mail/joe Feb 28 14:57:45 mouse dovecot: pop3-login: Login: user=<joe>, method=PLAIN, rip=192.168.6.20, lip=192.168.6.2 Feb 28 14:57:45 mouse dovecot: pop3(joe): Logout. top=0/0, retr=0/ del=0/0, size=0 This is almost exactly what we're chasing, except the new Maildir is not going to be created in the user's home dir, it will be in /mail/<first letter of username>/username. All attempts to make this last adjustment have ultimately modified the behaviour of dovecot so that it only checks the one source explicity given, and then simply fails if it does not exist, unlike the unconfigured behaviour illustrated above where it is able to fallback to a secondary source. A '2nd_default_mail_env' is the type of variable I'm looking to define, if that makes it any clearer. Any advice much appreciated, I've already searched most of the archives for this list without finding anything similar.

[Dovecot] Impact of log files on performance
by vmstech 27 Feb '06

27 Feb '06

Hi - im trawling through my config trying to reduce chances of timeouts etc - I use postgres for all the dovecot and exim4 authentication and location of mail directories etc - and found that by eliminating logging (or reducing to almost none) the queries invovled have gone from >500ms to <3ms - Just wondering if I'll get similar performance gains with dovecot (which is set to be verbose as I could) - esp during connection thx Glenn

Error the server is unavailable. Receiveing Reported error (0x800CC0F):'The connection to the server was interrupted' While these are from outlook - I often get one simiar to the first one in my evolution clients. Are these things that can be best managed with some sort of configuration change? What might be other possible causes of these (apart from a power cut to the server? thx Glenn

[Dovecot] RHEL4 configuration
by f00bar 26 Feb '06

26 Feb '06

I just installed a new email server using RHEL4. I only want pop3d services, no imap is desired so I modified the dovecot.conf file by changing to "protocols = pop3". All is working fine. However, dovecot requires access to /home/user/mail or the Thunderbird client hangs when attempting to download email. We have a single /home that is mounted by all servers for all users. We do not want the mail server to mount this /home. So I created directories with the usernames in the mail server's /home. This is not desired from a system management perspective. The files dovecot creates in the /home/user/mail directory appear to be for the use of IMAP which we do not use. How do I configure dovecot to not access /home and to not create any IMAP files? Thank you

Thanks I succeed with disable_plaintext_auth = no I think that it's not good for security. I'm looking for security with pop3s. I made a certificate with cacert.org
