[Dovecot] Cannot create auth-master file
by Greg Frith 09 Mar '10

09 Mar '10

Hi all, I'm trying to get postfix and dovecot working nicely together to process and store mail for both local (system) on one domain and virtual users and a few different domains. I've got postfix up and running quite nicely, but am having a few problems with Dovecot. Every time postfix tried to delivery a message to a virtual user using dovecot I get an error like the following in /var/log/mail.log: Mar 8 21:53:58 rhy postfix/pipe[6616]: 89C94846E: to=<gregf(a)gregsfamily.com>, orig_to=<greg(a)gregsfamily.com>, relay=dovecot, delay=8795, delays=8794/0.01/0/0.61, dsn=4.3.0, status=deferred (temporary failure) At the same instant, in my dovecot log I'll get this error: deliver(gregf(a)gregsfamily.com): 2010-03-08 21:53:58 Error: Can't connect to auth server at /var/run/dovecot/auth-master: Connection refused So, I'm guessing that this is a permissions issue (somewhere) and that the dovecot process is not able to create the file /var/run/dovecot/auth-master. The permissions on this folder are as follows: gregf@rhy:/etc/dovecot$ ls -al /var/run/dovecot/ total 0 drwxr-xr-x 3 root root 100 2010-03-08 21:44 . drwxr-xr-x 15 root root 660 2010-03-08 22:00 .. srw------- 1 vmail root 0 2010-03-08 21:43 auth-master srwxrwxrwx 1 root root 0 2010-03-08 21:43 dict-server drwxr-x--- 2 root dovecot 60 2010-03-08 21:44 login I've searched around for hours, found several threads describing similar issues, but no solutions that have worked for me. If anyone is able to give me any pointers or suggestions I would be most grateful. My dovecot configuration is: gregf@rhy:/etc/dovecot$ sudo dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-18-generic x86_64 Ubuntu 9.04 ext3 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps pop3s imap pop3 login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/home/vmail/%d/%u mail_debug: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: mechanisms: plain login user: vmail debug: yes debug_passwords: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail :wq G

[Dovecot] Using MySQL For Mailboxes?
by Carlos Mennens 09 Mar '10

09 Mar '10

I have always seen some people indicate they use MySQL for mailboxes in Postfix and I wondered how difficult something like this would be? I have 300 users on my company Postfix server right now. I am just using Postfix, Dovecot (IMAP4 only), & Roundcube (Webmail). I have MySQL loaded on the machine that runs Postfix but only to manage the database for Roundcube. Do you think that 300+ users is recommended for a MySQL database for mailboxes? Secondly, how difficult is it to configure this? Right now everyone user has a home directory and a mailbox in their private home folder. Is it hard to configure Postfix & Dovecot to use MySQL mailboxes? Just looking for some suggestions since I couldn't find a log of info via Google. *PS* I was told that Dovecot doesn't support MySQL mailboxes. I think it does. Am I wrong? http://howtoforge.com/forums/showthread.php?p=221396#post221396

[Dovecot] Pigeonhole Sieve date extension
by Edgar Fuß 09 Mar '10

09 Mar '10

Probably I'm doing something stupidly wrong. I have dovecot 1.2.7 and sieve 0.1.13. I have a sieve script starting with # <some comment> require ["vacation", "date", "relational"]; I get main_script: line 2: error: require command: unknown Sieve capability 'date'. Just to make sure I haven't messed up the dovecot package: $ strings /usr/pkg/lib/dovecot/lda/lib90_sieve_plugin.a | fgrep date_extension date_extension date_extension date_extension date_extension date_extension What's going on? It's probably some totally stupid typo on my side.

[Dovecot] force to recalculate quotadict
by Andre Hübner 08 Mar '10

08 Mar '10

Hello, i use working quotasystem with sql-quotadict. The values stored in db are used to realize also a quotasystem in postfix to reject mails if they are bigger then remaining quota. if dataset in quotadict is missing for some reasons, postfix can't calculate quota and mail gets delivered even if user is already over quota. I am looking for a way to force dovecot/lda to recalculate users bytes/messages with command xy and not to wait for incomming mail. Currently i use: deliver -d $user -n -m folderwithunspeakablenamesonobodyusesthis and send a small message which gets lost but starts the calculation. This works but seems not to be the finest way. Is there a better way or my current procedure acceptable? Thanks, Andre

Hello, > 1. remove the quota in the DB, > 2. make same changes. hmm, i see. but unfortunately this is not a way i can do. it would be acceptable in private scope but not for bussinesscustomers. to make a change i would manipulate customers maildata which is not allowed this way. a simple command to update complete quota for the single user would be the best way. now i tried to connect per telnet and use command Getquotaroot, seems also to work. this should be scriptable... ok thanks, i will try something...

[Dovecot] Saving Sent Messages to Sent Folder
by Charles Marcus 08 Mar '10

08 Mar '10

Hi Timo, There was another thread (it has come up at least a few times in the past few years I've been lurking) on the postfix list about having some kind of automatic 'Save to Sent' option to avoid the users mail client from having to upload messages twice (obviously the only ones of concern are ones with large attachments) - once to send it, and once to save the copy in the sent folder. I know and understand that doing this is not generally the job of the MTA, but hopefully most people can at least admit that there would be a (potentially huge, in the case of any large company that deals with a lot of large attachments in their email) savings in bandwidth (and user frustration) if a way could be found to do this reliably and at little to no 'cost' in terms of CPU/Disk IO, so I have a question about how this might be done... Given: Postfix can be configured to use the Dovecot LDA for delivering mail incoming. My question is simply, why wouldn't it be possible to create a Dovecot LSA ('submission agent'), that could be defined in postfix's master.cf file, which could then be configured to a) pipe the message to postfix, and b) if message is successfully sent, save a copy to the users Sent folder? Obviously, there would be some caveats - ie, postfix and dovecot would both have to be running on the same box (or at a minimum on the same local network)... Anyway, this is just something that really bugs me (and has for many, many years) every time I send a message with a large attachment, and have to watch it slowly process the message sending it, then again to save it to the Sent folder, so Ijust wanted to get your take on if this is even remotely feasible... -- Best regards, Charles

[Dovecot] 2.0 beta 3 w/o libwrap?
by Scott Ellis 07 Mar '10

07 Mar '10

I'm trying to kickstart 2.0b3 on my NetBSD system (where 1.2.x works great!), and keep hitting: Fatal: service(tcpwrap) access(/software/dovecot-2.0beta3/libexec/dovecot/tcpwrap) failed: No such file or directory Indeed, that file doesn't exist...but I don't have nor want libwrap. It appears that doveconf includes tcpwrap... service tcpwrap { chroot = client_limit = 1 drop_priv_before_exec = no executable = tcpwrap extra_groups = group = privileged_group = process_limit = 0 process_min_avail = 0 protocol = service_count = 0 type = user = $default_internal_user vsz_limit = 4294967295 } ...but nothing else seems to. Running configure with --without-libwrap doesn't make any difference (configure doesn't find libwrap anyway). What am I missing here? How can I use dovecot 2.0 w/tcp wrappers? ScottE

Re: [Dovecot] Number of users for one Solr instance
by Lee 05 Mar '10

05 Mar '10

Hi, This is my first mail, fyi. I dont know internals of the plugin but it depends more on Solr than Dovecot. Also the activity level and "real-timeness" of the index is important. Assuming this as the search only machine and relatively moderate usage, a big box with lots of RAM and 4-way server may work in your case. Lee

[Dovecot] Number of users for one Solr instance
by Ernesto Revilla 05 Mar '10

05 Mar '10

Dear all. (I'm new to the list.) Our regional government is considering, due to our proposal, migrate from Courier to Dovecot. 70k mailboxes. One of the most attractive features for them is the usage of indexes, and especially Solr FTS plugin. Their question is: How many users (range of users) could support one Solr instance used as index and search backend? Are there any deployment examples? I think, it would be easy to split users into different Solr instances, but it's not that easy to reorganize them, as we have to reindex if one user is moved from one instance to another. Regards. Erny Yaco Sistemas

[Dovecot] plugin Again
by Alex Baule 04 Mar '10

04 Mar '10

Hello.... Someone know ho work the istream-concat ? I made a copy of istream-concat, and use to manipulate my encrypted body. But i got some questions about the stream->pos, stream->skip and position of the message and pointer to buffer. My messages have the W= with the email size decrypted, and it is a little lass that the email size crypto. For exemple: I have a email with 6000k in crypto and decrypto the size is 5985 k: The buffer from istream-concat is 4096, i read 4096 from get_stream_data, but the result of this read is minor , lets say 4080, but the next read must be from 4096. The "send to client" must be 4080, to send the correctly data decrypted. My Question is, what the variable used in istream-concat, to send the data to client ? I need to update the stream->pos with my data length ?? I dont know if i made understand my question.....

[Dovecot] Dovecot 2.0.beta3: mdbox mailbox crashes upon login

I totally agree with the one of you who mentioned the online documentation and the wiki. I know that it exists and i used it for setting up my mail server, but ... as i said, i am old fashioned and i can better work with books. It's just a personal preferrence. Well, i also know that many developers are still working on dovecot, especially Timo and that always new features, configuration options and so on are added, but ... it's the same with other applications in the community (e.g. postfix, apache, OpenLDAP, samba ....) and for all those applications books are available, and that was the reason, why i asked for a book. And to be honest. When i go thru the documentation part, most of the documents were not changed for at least 6 months. I am sure that between the writing and the publishing of a book new dovecot features will be introduced and not covered in the book. But everyone working with books knows that they can't be up to date, but they are a real good basis for me to start with the fundamentals and then add this information by new data from the web. And guys just to mention one big advantage of a book is, you can read it offline easily!! But there is one thing i want to mention at this point. Even if you agree with me about having a book or not. What i really like is the discussion about and the chance to do so, because dovecot is opensource. And for me this is in the end the result behind the idea of open source. Everyone has the chance to contribute, either by code, by suggestions, by comments ..... And that for me is more important than to have a book or not. Thank you all for your comments.

[Dovecot] Dovecot 2.0b3 IDLE not advertised
by Bernhard Schmidt 02 Mar '10

02 Mar '10

Hi, I'm not sure whether the client or the server is at fault (probably the client), but it's clearly a regression for me. I'm using the LCG Profimail (http://lonelycatgames.com/?app=profimail) application for my Symbian smartphone which has quite decent IMAP capabilities. Amongst others it can do IMAP IDLE (which has to be statically enabled in the server settings, so it's not used based on the server capabilities). After upgrading from 1.2.10 to 2.0b3 it does not connect anymore. It throws the error message "This server doesn't support IMAP IDLE connection" in my face, even before it tries to authenticate Feb 27 00:46:45 mail dovecot: imap-login: Disconnected (no auth attempts): rip=93.104.73.132, lip=83.170.x.xx, TLS: Disconnected The main difference seems to be that 1.2 advertises IDLE in capabilities before authentication, but 2.0 does not: 1.2: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready. o CAPABILITY * CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC * ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH QUOTA STARTTLS AUTH=PLAIN o OK Capability completed. 2.0: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready. o CAPABILITY * CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN AUTH=LOGIN o OK Capability completed. o LOGIN user password * CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 * CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS QUOTA o OK Logged in I know there is the imap_capability setting which might help here, but that looks like a very big hammer.

Hi, 1) Why dovecot -n doesn't display default values? At least it didn't display mail_max_userip_connections(default): 20 mail_max_userip_connections(imap): 20 mail_max_userip_connections(pop3): 10 if I had set ONLY mail_max_userip_connections (to be =10) 2) "Maximum number of connections from user+IP exceeded (mail_max_userip_connections): " Could it be enhanced to actually log what the limit was at that time? -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

[Dovecot] dovecot 1.1.6 and outloook express 6 out of sync
by gyre 02 Mar '10

02 Mar '10

Apologies if this has been discussed before. I have dovecot 1.1.6 installed on my qnap NAS. I connect to the imap server using outlook express 6 on my XP sp3 box. I notice, after a time, that what I see in outlook express isn't what is actually on the imap server. For example, in one of my folders, many messages are missing. On another, headers of messages start getting duplicated and the bodies don't always match the headers. If I tell outlook express to clean up and reset... i.e. remove all the headers and bodies so they get downloaded again, then everything appears again... for a little while. Likewise, if I delete all the index files on the server and restart it, all seems well for a bit. Somehow, OE is getting out of sync with the imap server. This same OE client is also talking to other non-dovecot imap servers and I don't see this out-of-sync-ness or corruption at all. I realise this is a vaguely stated problem, but I'm not a imap person and dont yet know how to narrow it down further, nor can I reliably recreate it. Has anybody seen anything like this before? Thanks. -- gyre --

[Dovecot] What does mailman do with a 'post' command?
by Masaharu Kawada 02 Mar '10

02 Mar '10

Dear list, I am sorry if this question should not be posted here, but I believe that there are many experts of postfix or any other thing such as mailing lists in this list. I am kind of in hurry and need some advices to know about my questions. Could anyone in this list please answer my questions if you know. My questions are about routing work of mailman. As I am not quite fimiliar with the use of mailman, I am sorry if this is a stupid question. One of my customer gets the following log message into /var/log/maillog at around 12:00 every day. ---</var/log/maillog>--- 12:00:04 relay postfix/pickup[6279]: 244811C805C: uid=41 from=<mailman> 12:00:04 relay postfix/cleanup[21529]: 244811C805C: message-id=<20100215030004.244811C805C(a)example.co.jp> 12:00:04 relay postfix/qmgr[20068]: 244811C805C: from=<mailman(a)example.co.jp>, size=1728, nrcpt=1 (queue active) 12:00:04 relay postfix/local[21232]: 244811C805C: to=<mailman(a)example.co.jp>, orig_to=<mailman>, relay=local, delay=0.17, delays=0.05/0/0/0.12, dsn=2.0.0, status=sent (delivered to command: /usr/lib/mailman/mail/mailman post mailman) ---- This message seems that it delivers a command '/usr/lib/mailman/mail/mailman post' to execute against the mailman mailing list, however, the customer never use mailman mailing list on their system. One thing that I doubt is that a cronjob in /etc/cron.d/mailman does something relevant of this because the post time of the messages is always reight after the following work. ---</etc/cron.d/mailman>--- 0 12 * * * mailman /usr/lib/mailman/cron/senddigests or 0,5,10,15,20,25,30,35,40,45,50,55 * * * * mailman /usr/lib/mailman/cron/gate_news --- I'm afraid that I don't have /etc/mailman/aliases file of cutomer's, but by default(in my test env), it should looks like below. </etc/mailman/aliease> # STANZA START: mailman # CREATED: Mon Jan 25 16:48:18 2010 mailman: "|/usr/lib/mailman/mail/mailman post mailman" mailman-admin: "|/usr/lib/mailman/mail/mailman admin mailman" mailman-bounces: "|/usr/lib/mailman/mail/mailman bounces mailman" mailman-confirm: "|/usr/lib/mailman/mail/mailman confirm mailman" mailman-join: "|/usr/lib/mailman/mail/mailman join mailman" mailman-leave: "|/usr/lib/mailman/mail/mailman leave mailman" mailman-owner: "|/usr/lib/mailman/mail/mailman owner mailman" mailman-request: "|/usr/lib/mailman/mail/mailman request mailman" mailman-subscribe: "|/usr/lib/mailman/mail/mailman subscribe mailman" mailman-unsubscribe: "|/usr/lib/mailman/mail/mailman unsubscribe mailman" # STANZA END: mailman My questions are as follows. 1.What exactly is the cause the message in /var/log/maillog? 2.Why does the messages send to mailman(mailman(a)example.co.jp) user even though that mailing list never be used?

[Dovecot] segfault - (imap|pop3)-login during nessus scan
by Todd Rinaldo 01 Mar '10

01 Mar '10

We've been struggling with a problem for the past couple of days which to this point I've only gotten to be able to boil down to this: 1. Install nessus home edition (less pluggins I assume) 2. run all scans (sequentially or in parallel, doesn't seem to matter) 3. about 3 minutes in /var/log/messages will show segfaults on imap and/or pop3 imap-login[22185]: segfault at 000000000000000c rip 0000003c7de610a2 rsp 00007fffa2342068 error 4 or sometimes... pop3-login[24451]: segfault at 000000000000000c rip 0000003c7de610a2 rsp 00007fff07116968 error 4 I'm having a really hard time getting a core dump and I'm having a really hard time narrowing down the list of nessus tests which cause this. So far, I have repeated this failure in 1.1.19 and 1.1.20 Additionally we've seen something similar on 1.2 and reverted back to 1.1 a year ago. At the time we could not re-produce a test case and finally gave up. Has anyone seen something along these lines? Can anyone recommend how I could narrow this down further so we can find the problem? Thanks, Todd

[Dovecot] Read-only imap mailbox and disable pop access to it
by foram goram 01 Mar '10

01 Mar '10

Hi I want to create a mailbox that no one would be able to delete mails from and disable access to it through pop. I have come up with using ACLs to allow read-only access to users. Is that right approach? Could someone tell me how I can achieve the second objective of disabling pop access to this mailbox only.

I just setup squat and after a long first search on that 50MB, 11K+ messages mbox file, every search after the first has taken less than 5 seconds, most only 2 seconds. It's performing exactly as I'd like. It's amazing. I didn't ever setup any fts plugins on 1.0.15. I'm left wondering how body searches were so fast if I didn't have an fts plugin configured.

[Dovecot] any limitations running on a Mac?
by Terry Barnum 28 Feb '10

28 Feb '10

I have postfix/dovecot/mysql installed using MacPorts on a quad-core 2.8GHz MacPro running Snow Leopard (10.6.2). I moved the base mail directory to a pair of 10k RPM Raptors that are mirrored (/Volumes/email/) and everything seems to be working fine on an unused domain with very little traffic. I used imapsync to pull everything from the current mailserver to this test server to play with. Our current mailserver's IMAP performance *really* suffers when an IMAP folder exceeds ~500MB or ~5k messages. I've become very tired of being the mailbox police trying to get my 20 users to delete email or divide into smaller mailboxes. Are there folks on the list running postfix/dovecot on similar Mac hardware that can share their experiences? Specifically, are there any limitations (file descriptors, other?) that can impact performance I should be aware of? How does dovecot on the Mac deal with >500GB maildirs? Is there a recommended tool for loading and testing the server? Postal? I have 20 IMAP users, with a total of ~37GB of mail currently. Thanks for any help and insight. -Terry Terry Barnum digital OutPost San Diego, CA http://www.dop.com 800/464-6434

[Dovecot] client cert handling not working properly on centos 4.8
by zhong ming wu 28 Feb '10

28 Feb '10

Dear List I've successfully installed/configured dovecot 1.2.10 with "require client cert" on centos 5.4 and ubuntu server 9.10 I also need to install on centos 4.8 and after the following the exact same procedure I can only get it working if I commented out ssl_require_client_cert =yes and ssl_username_from_cert = yes from the working config file. This is even after compiling dovecot with openssl 0.9.8l on centos 4.8 If I copy the same "client_ca.crt" from centos 4.8 to centos 5.4 then centos 5.4 does not problem in verifying client cert. That file contain CRL as well as certificate which signs the pkcs12 file installed on the client.

[Dovecot] IMAP Folders Don't Make Sense

I noticed for some reason that I am missing an IMAP folder called 'Symantec' that was under my Inbox. I see all my other folders listed on my mail client except 'Symantec'. I then login to my mail server which runs Postfix / Dovecot & there I can see it: /home/cwilliams/Maildir [root@mail Maildir]# ls -la total 608 drwx------ 33 cwilliams it 4096 Feb 25 13:23 . drwx------ 5 cwilliams it 4096 Feb 23 13:24 .. drwx------ 2 cwilliams it 53248 Feb 25 13:22 cur -rw------- 1 cwilliams it 3048 Feb 25 12:42 dovecot.index -rw------- 1 cwilliams it 178176 Feb 25 13:22 dovecot.index.cache -rw------- 1 cwilliams it 54936 Feb 25 13:23 dovecot.index.log -rw------- 1 cwilliams it 131124 Feb 10 16:18 dovecot.index.log.2 -rw------- 1 cwilliams it 121 Jul 15 2009 dovecot-keywords -rw------- 1 cwilliams it 8190 Feb 25 13:13 dovecot-uidlist drwx------ 5 cwilliams it 4096 Feb 25 12:47 .Drafts drwx------ 2 cwilliams it 4096 Feb 25 13:27 .INBOX drwx------ 5 cwilliams it 4096 Feb 25 08:55 .INBOX.ClamAV drwx------ 5 cwilliams it 4096 Feb 25 08:54 .INBOX.Dell.Quotes drwx------ 5 cwilliams it 4096 Feb 25 08:54 .INBOX.Dell.Warranty drwx------ 5 cwilliams it 4096 Feb 25 08:55 .INBOX.IBM drwx------ 5 cwilliams it 4096 Oct 2 2008 .INBOX.Logs drwx------ 5 cwilliams it 4096 Feb 25 08:55 .INBOX.Red Hat drwx------ 5 cwilliams it 4096 Feb 23 09:26 .INBOX.Symantec drwx------ 2 cwilliams it 32768 Feb 25 13:13 new drwx------ 5 cwilliams it 4096 Feb 25 13:25 .Sent drwx------ 5 cwilliams it 4096 Feb 17 08:37 .Spam -rw------- 1 cwilliams it 393 Feb 23 10:23 subscriptions drwx------ 2 cwilliams it 4096 Feb 25 13:13 tmp drwx------ 5 cwilliams it 4096 Feb 25 13:22 .Trash As you can see above there is a .INBOX.Symantec directory and I can 'cd' into it and see all my messages: /home/cwilliams/Maildir/.INBOX.Symantec [root@mail .INBOX.Symantec]# ls -l total 280 drwx------ 2 cwilliams it 12288 Jan 21 17:39 cur -rw------- 1 cwilliams it 2352 Jan 21 17:39 dovecot.index -rw------- 1 cwilliams it 233472 Feb 22 08:17 dovecot.index.cache -rw------- 1 cwilliams it 8428 Feb 22 08:17 dovecot.index.log -rw------- 1 cwilliams it 41 Oct 12 09:50 dovecot-keywords -rw------- 1 cwilliams it 6665 Jan 21 17:39 dovecot-uidlist drwx------ 2 cwilliams it 4096 Oct 2 2008 new drwx------ 2 cwilliams it 4096 Jan 21 17:39 tmp However when I open Thunderbird & Webmail (both use IMAP), I see my Symantec folder under a 'Drafts' folder.

I am confused. Please help! Thanks!

[Dovecot] Little Help with Plugin
by Alex Baule 26 Feb '10

26 Feb '10

Hi everyone..... I Build a plugin to concat my body and header splited.... Its have 2 "versions". One is with the body without modifications. The second, is with the body with crypto, and this crypto increase a little the size of email. So, without crypto, works fine, but with crypto i got stuck in some modifications. Because the email is splited, to handle it, i made a copy from istream-concat.c, and in i_stream_concat_read i made this changes. Every place that have the i_stream_get_data i get the index from concat (if is the frist or second stream) and if is the second, (my body) the unsigned char *data is the return from my function. if(cstream->cur_idx == 1){ data = decrypt_data(cstream->cur_input, &data_size); }else{ data = i_stream_get_data(cstream->cur_input, &data_size); } In this part, i get the function i_stream_get_data and put in the function too, to get the data in the same way, but i dont return the (_stream->buffer + _stream->skip;), i put this in a unsigned char * too, and work with this variable. The size_r, with the _stream->pos - _stream->skip, i update it, with the new value get from my total length from the decrypted buffer. In resume, every (inside istream_concat_read and istream_concat_read_next ) i_stream_get_data(cstream->cur_input, &data_size); // (in istream_concat_read is "pos" variable) I change to if(cstream->cur_idx == 1){ data = decrypt_data(cstream->cur_input, &data_size); //(in istream_concat_read is "pos" variable) }else{ data = i_stream_get_data(cstream->cur_input, &data_size); //(in istream_concat_read is "pos" variable) } Setting the unsigned char *data, with my decrypted data and the pos or data_size, with the length of buffer data , decrypted. I Think there is Ok with this, and must be work, but i got some errors with this, when the Email is read to get them, the total length read is diferent from the W flag in header name. FETCH [] for mailbox INBOX UID 2 got too little data: 1351 vs 1352 FETCH [] for mailbox INBOX UID 1 got too little data: 1357 vs 1360 FETCH [] for mailbox INBOX UID 3 got too little data: 691 vs 1303 There is some variable or something that i forgot to update with this news values ? I use the Zlib plugin for exemple to do this. Tks Guys !!!

[Dovecot] Regarding: **OFF LIST** subject declaration
by Jerry 25 Feb '10

25 Feb '10

Seriously, I just have to ask this question. Why mark via the subject line a message as "OFF LIST" and then send it via the normal list framework. Doing so only insures that the message is actually "ON LIST" irregardless of what nomenclature is used in the subject line. If a message is truly supposed to be "OFF LIST", then why not send it directly to its intended recipient(s)? If, on the other hand, it is meant for general review by the groups members, then why mark it "OFF LIST" to begin with? I am aware of the prefix "OT" used in several forums; however, that is usually only used to thwart the moderator of the forum from banning the message or chastising the OP. Its use is of dubious success. -- Jerry gesbbb(a)yahoo.com |::::======= |::::======= |=========== |=========== | The course of true anything never does run smooth. Samuel Butler

[Dovecot] FTS cron script to force index updates
by Stan Hoeppner 25 Feb '10

25 Feb '10

From: http://wiki.dovecot.org/Plugins/FTS "You could also build a cronjob to index users' mailboxes once in a while (by selecting each mailbox and issuing a SEARCH TEXT xyzzyx command)." Has anyone written a script to perform the above? If not, how would I do this? Would I write a shell script to telnet to the IMAP port and then issue the commands? Can this be done with a bash script? Or would I need something more serious like a perl script? Thanks. -- Stan

[Dovecot] dovecot2 Beta2: different certs for imaps and pop3s

Hello, is it possible to use differnent ssl certs for pop3 and imap ? I like to have differnet dnsnames for pop3 an imap services configured at customers clients. I tried to configure ssl_key and ssl_cert inside a <protocol>-login {} section but this failed. Of course I know sslcerts containing multiple dnsnames.

You are conflating UI blocking with network blocking (download), probably because that's how TB does it. IMHO, when you open a mailbox, messages should fill in and be accessible immediately, ie as soon as the headers are downloaded. Beyond a screenful, the client should continue to download headers so that when you do scroll down, there is no delay. This is especially useful when you are on a slow link. You spend SO much time doing nothing, ie reading messages, while the client could be doing work for you, and then when you scroll you have to wait again? Also you have to adjust this behavior if server-side sorting is not available and the user wants something other than message order. If you're worried about "wasting" bandwidth, a valid concern, the client need only prefetch another screenful of messages at a time. If your client is configured to sync message bodies, it should go ahead and do that before you start actually reading them, so that you are not waiting on download. Apple Mail, for one, seems to implement things as I've described. Note I am in now way endorsing Apple Mail as a good IMAP client. -frank

[Dovecot] antispam plugin
by Dan Swartzendruber 24 Feb '10

24 Feb '10

First off, I have to say I really like the antispam plugin. I am running a (relatively) new freebsd 8.0 server with postfix/dovecot/dspam/squirrelmail and it works great. Create a SPAM folder and tell the dovecot antispam plugin to use INBOX.SPAM as the spam folder and drag messages from INBOX to the spam folder and they are trained as spam. Here is the problem though: after training dspam for a couple of weeks, I had a couple hundred messages in the SPAM folder, so I selected them and hit the DELETE button and they were gone. Except they weren't. I had forgotten that by default squirrelmail moves deleted messages to a Trash folder under INBOX. So the messages were moved out of the SPAM folder, resulting in them being retrained as ham. Oops :( I then hit the purge link in squirrelmail and the messages were forever gone, so I couldn't rectify my gaffe. I have temporarily reconfigured squirrelmail to delete messages outright rather than save them in the Trash folder, but I don't like that as a long-term solution. What occurred to me is this: the current algorithm is: if message moves from * => SPAM, it is trained as spam, if it moves from SPAM => *, it is trained as ham. It would be nice if you could elaborate on that such that the ham rule was "if message moves from SPAM to X, it is ham" (and in my case, I would defined X as INBOX. Thoughts?

[Dovecot] OT: best linux imap client for dovecot
by Axel Thimm 24 Feb '10

24 Feb '10

Hi, I'm a long term dovecot user, packager and believer, but on the other side of the wire I've been a mutt user for longer than I can think. Which modern email client under Linux is working best with dovecot? I just did a grep on User-Agent:/X-Mailer: on my dovecot archive (which goes back to 2004) and found that the top ten are: 28% Thunderbird 25% Evolution 9% Apple Mail 9% Mutt 5% Mozilla 3% KMail 2% Outlook 2% SquirrelMail 1% Alpine 1% Mulberry ... So it looks like most Linux people here like to use Thunderbird and Evolution. This is not a my-email-client-is-better-than-your-email-client thread, I just want to know which client(s) make proper use of imap features for fast searches/copies/deletions etc. Thanks! -- Axel.Thimm at ATrpms.net

[Dovecot] namespaces/virtual folder & archiving
by fernando＠dfcom.com.br 24 Feb '10

24 Feb '10

Hi, I was following the earlier namespaces discussion and I would like to repost a doubt. I need to have some kind of archiving, it means, store old messages into a cheap storage. But I couldn´t think any other solution than symlinks. Then, I thought about store 'Sent Items' (as having old messages and less acessed). But I also needed to do with nfs and symlinks. So, it comes the namespaces discussion and a little brainstorm: 1) Could I have a namespace only with INBOX and the personal folders (drafts, sent items, etc) in another one - and those would be stored in huge sata disks while inbox in 300g sas disks ? 2) Could I maintain the prior configuration, but let the second namespace hidden and having the inbox subfolders (or any specific as sent items) as virtual folder ? I don´t know if this makes sense... 3) Could I have my normal Inbox and a folder (in another disk - ex. huge sata one) storing files older than 30 days and through virtual folders join these messages in a common virtual INBOX while acessing imap or pop3 ? What do you thing, would you have another better approach ? Best Regards, Fernando

[Dovecot] Installation directories layout question
by Hunny Bunny 24 Feb '10

24 Feb '10

Hello folkz, I'm trying to compile and install Dovecot 1.2.10 from sources. When I execute: ./configure --prefix=/usr/local/dovecot make make install I reasonably expect to find dovecot libraries in /usr/local/dovecot/lib but it puts them into /usr/local/dovecot/lib/dovecot. It add this extra 'dovecot' at the end of almost every installation path. Could somebody please clarify what extra configuration parameters should be set to make to change this strange dovecot installation directories layout. Thank you very much in advance, Alex

[Dovecot] body search very slow since upgrade from 1.0.15 to 1.2.10
by Stan Hoeppner 24 Feb '10

24 Feb '10

Did you mislead me Timo? You said search in 1.1+ is faster than 1.0. I'm seeing approximately 20x *slower* search times in 1.2.10. Via Thunderbird, a full body search of my 11,000+ message IMAP folder hosted by 1.0.15 used to take less than 10 seconds. Since upgrading to 1.2.10 the search is taking over 3 minutes, the imap process servicing the client pegging one CPU at 100% for the duration of the search. Here's the mbox file: -rw------- 1 stan stan 50M Feb 23 07:41 1-Spam-l Doing the same search via grep results in a time of: real 0m0.361s user 0m0.204s sys 0m0.140s grep takes less than half a second, yet dovecot 1.2.10 takes 3 minutes for the same search? Actually grep is searching the entire file including headers, so it's doing more work than the imap process. Something is *SERIOUSLY* wrong here. Did I somehow nerfed something in dovecot.conf that's causing this? I deleted all the index files as per the upgrade instructions. However, checking the directories shows they're apparently rebuilt: [08:09:15][root@greer]/home/stan/mail/.imap/1-Spam-l$ la total 28M drwx------ 2 stan stan 4.0K Feb 23 07:41 . drwx------ 35 stan stan 4.0K Feb 15 11:14 .. -rw------- 1 stan stan 358K Feb 23 07:18 dovecot.index -rw------- 1 stan stan 27M Feb 23 07:41 dovecot.index.cache -rw------- 1 stan stan 616 Feb 23 07:41 dovecot.index.log What do I need to check/change/do to get these search times back down to reasonable/respectable levels, i.e. around 10s? Thanks. -- Stan

[Dovecot] 1.2.10: namespaces and still no luck
by Toni Mueller 23 Feb '10

23 Feb '10

Hi, I'm trying to set Dovecot up in a way that is compatible with console usage of the same mailboxes (ie, w/o IMAP). My mailboxen are almost all maildirs (I can ignore all other formats), and are laid out as follows: INBOX = ~/Maildir All other folders are maildirs in ~/Mail Eg. ~/Mail/archive, ~/Mail/sent, ~/Mail/some-mailing-list I configured this, along the lines of http://wiki.dovecot.org/Namespaces: # I unset 'mail_location' namespace private { separator = '/' prefix = location = maildir:~/Maildir inbox = yes list = yes subscriptions = yes } namespace private { separator = / prefix = archives/ location = maildir:~/Mail hidden = no #subscriptions = yes inbox = no list = yes } which I thought should do it, but it doesn't. In TB (3, if it matters), I see: Inbox Trash archives Trash Inbox (shaded) directory (shaded) And that's about it. I don't see any of the pre-existing maildirs in ~/Mail. I also can't delete the two additional "Inbox" and "Trash" folders, and I can't subscribe to the second "Inbox", nor to "directory". I proceeded to create a new folder under "archives", which mostly ended up to be a new maildir + index files under ~/Mail, but it had a '.' in front of it. Also, the separator was automatically reset to '.' for the second namespace, as I found out when I renamed one of the directories from 'dir.1' to '.dir.1'. Am I still doing something wrong, or is this a bug or limitation in Dovecot, or in this version of it? Kind regards, --Toni++

[Dovecot] Occasional problem with POP3-Download
by Andre Tann 23 Feb '10

23 Feb '10

Hello everyone, I have two mailservers [1] running dovecot. Mail store format is maildir. Every once in a while I have the following problem: When a User downloads his mail via POP3, the client says something like "the server has closed the connection unexpectedly, and gives this reason: [...blahblah...]". One can now cancel the download, and restart it, and the problem shows up again and again. The first few mails get downloaded, and then the process stops. Strange to say the "blahblah"-portion is a piece of text out of the email that doesn't want to get downloaded. Then I remove this single message out of the Maildir/cur-directory, and everything is fine again. It is easy to figure out which mail to delete because it's the first one that is not market as seen [...] filename...:2,S otherfilename...;2, <= this file must be deleted [...] For me it looks as if dovecot had a problem with some byte sequence in this mail, and for some reason it gives an error message to the client which is taken out of the mail. On the SuSE-Machine, before dovecot there was a courier-imapd running, which never showed this kind of problem, so it should not be a client problem. Hopefully my description is clear enough. Does anyone have an idea what's going on here? Thanks. Andre [1] One machine is a openSuSE 11.2 with # rpm -qa | grep dovecot dovecot12-backend-sqlite-1.2.9-0.1.1.i586 dovecot12-backend-mysql-1.2.9-0.1.1.i586 dovecot12-backend-pgsql-1.2.9-0.1.1.i586 dovecot12-1.2.9-0.1.1.i586 The other machine is a Debian Lenny with # dpkg -l | grep dovecot dovecot-common 1:1.0.15-2.3+lenny1 dovecot-imapd 1:1.0.15-2.3+lenny1 dovecot-pop3d 1:1.0.15-2.3+lenny1 -- Andre Tann

[Dovecot] v2.0 IMAP Capabilities announcement
by Thomas Leuxner 23 Feb '10

23 Feb '10

Hi, I have an Android Mail App which worked fine with IDLE pushes before (K-9 Mail) under 1.2.10. With 2.0 beta 3 it seems to be looking for an IDLE prompt from the server, otherwise it will disable connection idling (whether this is valid or not). Setting 'imap_capability = IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID IDLE ENABLE' does the trick, but is it possible to add additional values to the default reply like this? imap_capability = +IDLE ...or whatever syntax/form one would chose to preserve internal defaults. Thanks Thomas

[Dovecot] show only subscribed folders
by Frank Cusack 23 Feb '10

23 Feb '10

is there a plugin or some other method by which i could have a user ONLY have access to subscribed folders? having a separate login or a separate instance of dovecot is ok if necessary. the iPhone always shows ALL folders, not just subscribed ones. i'd like to be able to see only the subscribed folders.

[Dovecot] Dovecot 2.0.beta3 Configuration issue (I think)
by Mark Sapiro 23 Feb '10

23 Feb '10

I have been running dovecot 1.2.10 without problems. I am trying to install 2.0.beta3. I have I think translated all my configuration customizations correctly, but I have problems. I can start dovecot, but I can't login, at least not with SSL. Here's my dovecot -n # 2.0.beta3: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.18-8.1.14.el5 i686 CentOS release 5 (Final) auth_mechanisms = plain apop login auth_worker_max_count = 5 mail_location = mbox:~/Mail:INBOX=/var/spool/mail/%u mail_privileged_group = mail mbox_write_locks = fcntl dotlock passdb { args = /usr/local/etc/dovecot.passwd deny = no driver = passwd-file master = no pass = no } passdb { deny = no driver = pam master = no pass = no } ssl_cert = /etc/postfix/sbh16-cert.pem ssl_key = /etc/postfix/sbh16-key.pem userdb { driver = passwd } Note the files /etc/postfix/sbh16-cert.pem and /etc/postfix/sbh16-key.pem exist and are the same files I use with dovecot 1.2. Dovecot starts OK, but when I try to connect with a pop3 or imap client, the connection is established, but no response is sent to the client.

[Dovecot] v2.0.beta3 released
by Timo Sirainen 22 Feb '10

22 Feb '10

http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta3.tar.gz http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta3.tar.gz.sig I had to break a few APIs in this release to get some other stuff implemented and fixed. And since I had to break some of them, I decided it could be a good time to do some other less necessary API cleanups. This made things again much simpler. I'm hoping to get v2.0.rc1 out in not too distant future. Pretty much the only big missing feature that I wanted to do is being able to add per-protocol auth settings (e.g. protocol smtp { userdb { .. } }), but that doesn't seem to be all that easy to implement. There are of course some bugs still left to be fixed, mainly related to mdbox and dsync. User visible changes: - imap_zlib plugin implements COMPRESS=DEFLATE IMAP extension - zlib plugin: Added support for compressing mails while saving - zlib plugin: fixed reading bzip2 compressed mail files - zlib plugin: Added support for dbox and mdbox formats - mdbox: doveadm purge moves old mails to alt storage (if using alt storage) - added support for tcpwrappers - added support for SHA512 password scheme (by Mark Washenberger) - mailbox deletion is now free of race conditions (e.g. quota calculations). if another session tries to access mailbox before it's fully deleted, it'll get "Mailbox is being deleted" error. - "key = $set" in config file now sets key's value to "set" setting's value. this is probably rather limited outside the only place where I created it for: service { user = $default_internal_user } - default_internal_user and default_login_user settings now specify what users should be used for them. currently the default is still dovecot and dovecot, but I'm hoping to change default_login_user to something else.. - Removed maildir_copy_preserve_filename setting. It's now always tried to be preserved (or rather: message's GUID is preserved) - auth failure penalty tries to avoid increasing penalty for IP if auth is failing always with the same user+password combination. - doveadm penalty command can be used to see the current penalties - login processes: config lookups are now cached, so it no longer asks for configuration from config process every time (except if there are remote {} blocks in config. also the local {} caching could be smarter.) - Tons of mdbox fixes - Tons of dsync fixes, especially with mbox So some of the changes visible to developers are: - dovecot-config file changed. if your external plugin uses this file, you need to change it to use the new format. - added dovecot.m4 file that can be used by external plugins' configure script to get Dovecot settings. This was mainly done by Dennis Schridde. - mailbox_alloc() no longer has stream parameter, instead there's mailbox_open_stream() - mailbox_close() renamed to mailbox_free(). added a different mailbox_close(), which only closes opened mailbox, but doesn't free it. - mailbox_delete(), mailbox_rename() APIs changed - notify plugin's delete/rename API changed as well - mailbox GUID is now looked up using mailbox_get_guid(), not mailbox_status() - dict_iterate*() API changed

[Dovecot] Highly Performance and Availability
by Wayne Thursby 22 Feb '10

22 Feb '10

Hello everyone, I am currently running Dovecot as a high performance solution to a particular kind of problem. My userbase is small, but it murders email servers. The volume is moderate, but message retention requirements are stringent, to put it nicely. Many users receive a high volume of email traffic, but want to keep every message, and *search* them. This produces mail accounts up to 14+GiB. After seeing the failures of my predecessors, I transitioned to Postfix/Dovecot and haven't looked back. Things are running nicely with the below setup. Postfix and Dovecot running on the same virtual machine on a Dell 2950 with 1x Xeon E5440 on ESXi 4. Maildirs served up by 10x146GB 15k RPM SAS drives on RAID-10 via direct attached Dell MD-1000. We are transitioning other services to high availability, and I'm wondering exactly how to provide some kind of near-realtime failover for my Postfix/Dovecot machine. The MD-1000 provides nothing in the way of iSCSI, but it *does* have two SAS connections available, only one of which is in use. I have been looking at the Dell EqualLogic stuff and it seems to provide what we need. I can get most of the information I need from the rep, but I wonder if anyone has any experience with high performance requirements on these kinds of storage. I'd like to continue running my current hardware as the primary mail server, but provide some kind of failover using the SAN. The primary usage of the SAN will be to make our 2TB document store highly available. I'm wondering what kind of options I might have in the way of piggybacking some email failover on this kind of hardware without sacrificing the performance I'm currently enjoying. Is it possible to go with a virtual machine mounted on iSCSI acting as a backup mail server? How would I sync the two, NBD+MD? Any experience doing this with maildirs? I wonder about the performance. Can it be as simple as attaching my MD-1000's second controller to the SAN magic box via SAS and pressing the Easy button? Is it as expensive as running my primary mailserver mounted from the SAN via Fiber Channel? Will that get me under 30ms latency? I welcome any suggestions the group may have. -- Wayne Thursby System Administrator Physicians Group, LLC

[Dovecot] Best inode_ratio for maildir++ on ext4
by Rodolfo Gonzalez 22 Feb '10

22 Feb '10

Hi, This might be a silly question: which would be the best inode ratio for a 5 Tb filesystem dedicated to Maildir++ storage? I use ubuntu server, which has a preconfigured setting for mkfs.ext4 called "news" with inode_ratio = 4096, and after formating the fs with that setting and then with the defautl setting I see this difference of space (wasted space, but more inodes): 4328633696 free 1K-blocks with mkfs's "-T news" switch = 1219493877 free inodes 4557288800 free 1K-blocks with default mkfs settings = 304873461 free inodes I'll be storing e-mail messages for around 20,000 accounts on that partition (average 512 Mb per account). Would you consider worth the waste of about 200 Gb of the filesystem space in exchange of more inodes? Thanks. Rodolfo.

[Dovecot] Dovecot blog
by Timo Sirainen 20 Feb '10

20 Feb '10

http://blog.dovecot.org/ I was thinking that I could blog about: - ideas for new Dovecot feature designs - when I actually manage to implement some new great feature - maybe some stuff about IMAP/email in general - and maybe whenever I happen to be moving to a different country I wasn't really planning on announcing new releases there. Dovecot feature designs are also sent to Dovecot mailing list, as before. But there have been other things I've thought about mentioning somewhere, but Dovecot ML didn't really seem like the right place. I doubt I'll update the blog very often. But that probably makes it even more useful, since casual readers find the useful stuff quickly. :)

[Dovecot] Virtual POP3 Inbox question
by Josephus 20 Feb '10

20 Feb '10

Hi, I'm having trouble implementing the virtual pop3 inbox solution in Dovecot 1.2.x. As the following wiki page describes (http://wiki.dovecot.org/Plugins/Virtual) one should only set the inbox=yes flag for the virtual namespace which then flattens all mailboxes in the realmails/ prefix. In the above example when I set the inbox=yes flag for the virtual namespace, the inbox in the realmails/ prefix gets left out for obvious reasons. How did the original author intend this to work?

[Dovecot] Dovecot design-question
by Werner 20 Feb '10

20 Feb '10

Hi everybody, we're currently in the process of drafting our new mailserver-setup. Instead of a single-server-setup we'd like to have two equal servers behind a loadbalancer like LVS and shared mailhomes on NFS. We'd like to use dovecot for POP/IMAP, dovecot-deliver as LDA. - It's probably the best idea to direct SMTP and POP/IMAP always to the same server behind the loadbalancer (because dovecot-deliver is used which updates indexes?) - If we think of a "active/passive" setup: dovecot index-files locally or on the nfs-share? - Is it possible to activate loadbalancing for SMTP in this environment if dovecot index-files are held locally on each machine (POP/IMAP is directed only to one of the two servers?) Any comments welcome :-) Werner

[Dovecot] exporting client socket to postfix
by zhong ming wu 20 Feb '10

20 Feb '10

Dear List, I have a few questions regarding dovecot sasl authentication that are somewhat related to each other. I have a working dovecot config with ---------- ssl_verify_client_cert = yes .. . ssl_require_client_cert = yes ssl_username_from_cert = yes --------------- (With this set up I need not set a correct user name in my mail client so long as I have it correctly in cert.) It turns out that I cannot export client socket to postfix to do smtp authentication unless I comment out ssl_require_client_cert=yes Does it mean that postfix is not passing to dovecot any information about certificate? Is passing certificate information not part of sasl framework? If so I won't be able to use it with a different sasl implementation. Also if I comment out ssl_require_client_cert=yes, then I can no longer use username from cert to log in to retrieve my pop mail. I prefer to get username this way otherwise my thunderbird mailbox reads user@domain.org@domain.org; I could have more than one domain in my dovecot servers. Thanks mr.wu

[Dovecot] passing parameters to deliver

Is any posibility to pass parameters/environment variables to deliver with sieve plugin?

So far I write it to maildirs, but I wonder to migrate to mdbox, and procmail can't handle it. Any ideas?

[Dovecot] Feature request? Make deliver quota inclusive!
by Joachim Boltz 19 Feb '10

19 Feb '10

hi all, I'd like to make deliver put mail into a nearly full mailbox even when they become overquota as a result. The same problem came up a few weeks ago: http://dovecot.org/list/dovecot/2010-January/045695.html Since no solution was offered may I suggest this topic as an additional feature for future releases? ;-) This is a important for me because sometimes users are lazy. They think "oh, still 10% left, no reason to delete mail" while in the meantime large messages are already bounced, while some small ones arrive in the users inbox. cheers, achim

[Dovecot] Client behaviour with sieve
by Koenraad Lelong 19 Feb '10

19 Feb '10

Hi, I have a working dovecot imap-server, with sieve. I find it odd that my mail-clients (Thunderbird 2 and 3) don't report anything that's new in the folders. What I mean is this : Postfix get's a mail and hands it over to dovecot's LDA and sieve moves it to a folder. When I log in with Thunderbird, I see new messages in my Inbox. But that message that was moved to a folder is "invisible" until I click on the folder. Then Thunderbird sees there are new messages in that folder and reports the number of new messages and makes the foldername bold. Is this the expected behaviour ? Or did I configure something wrong ? Thanks for any clarification. Regards, Koenraad Lelong.

[Dovecot] wish now I'd not upgraded...
by Stan Hoeppner 19 Feb '10

19 Feb '10

Upgraded from Debian Dovecot 1.0.15 to Debian Dovecot 1.2.10-1~bpo50+1. I use Postfix local delivery to and Dovecot mbox. As per upgrade directions, I stopped dovecot processes and deleted all dovecot.index.cache files in /home/%user/mail/.imap. Performed upgrade to 1.2.10-1~bpo50+1. Modified new dovecot.conf for my environment. Started dovecot. Problem: Instantly noticed in TB 3.0.1 Win32 that all emails in all folders were marked as unread. Stopped TB, stopped dovecot, deleted *all* files in /home/%user/mail/imap/ so indexes and caches could be rebuilt from scratch. Started dovecot, started TB. Same problem. Then I got ugly, stopped TB and dovecot, deleted all ~.imap/ files *and* deleted *all* TB cache and index files with a time stamp of today. Restarted dovecot, restarted TB. Same damn problem. I sit hit right clicking folder after folder and selecting "mark as read", only to see all the emails in the folder go "read" and then within seconds go back to marked as unread (bold). Opening messages one at a time and moving to the next doesn't even keep them marked as read. WTF is going on? Why won't they stay marked as read? I've got over 25,000 emails in these folders and I get a few hundred list mails a day. I really need to get this read/unread business straightened out. What the heck am I missing? Is this a bug in the Debian backport? Good thing I have no hair or I'd have pulled half of it out by now... -- Stan

[Dovecot] quota problem
by Andre Hübner 19 Feb '10

19 Feb '10

dovecot 1.0.15 Hello, i try to set quota settings for my users. currentyl i use a mysql table for auth process and now i want to add quotasettings for each individual user. at the moment i have the problem that only global quota is effective and no userquota which is stored in usertable. This is my mysql-usertable: login varchar(255) password varchar(64) home varchar(128) uid int(11) gid int(11) quota_kb varchar(10) active char(1) In my main-dovecot.conf i have quota/imap_quota activated for pop/imap and protocol lda This is the auth-section which contains passdb/userdb auth default { mechanisms = plain login passdb sql { args = /etc/dovecot-sql.conf } userdb sql { args = /etc/dovecot-sql.conf } user = root socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } socket listen { client { path = /var/run/dovecot/auth-master mode = 0755 user = nobody } } } SQL-queries in /etc/dovecot-sql.conf (connection itselfs is ok, auth per mysql is working already) password_query = SELECT login as user, password, home as userdb_home, uid as userdb_uid, gid as userdb_gid FROM mail_users WHERE login = '%u' AND active='Y' user_query = SELECT login as user, home, uid, gid, concat('dirsize:storage=', quota_kb) AS quota FROM mail_users WHERE login = '%u' I think there is something missing in my conf but have no idea what it could be. I need a little hint please. Thanks, Andre

[Dovecot] auth processes
by Stan Hoeppner 19 Feb '10

19 Feb '10

With 1.0.15 my configuration I a single dovecot-auth process, which is what I want now. Since upgrading to 1.2.10 I have two such processes: root 16992 16990 0 Feb15 ? 00:00:00 dovecot-auth root 16997 16990 0 Feb15 ? 00:00:00 dovecot-auth -w I can't seem to tweak dovecot.conf to get this down to one auth process again. I've tried setting each of these below to 0, which resulted in either none, or one auth process. In the case of the one auth process, T-Bird wasn't working correctly, although it presented no pop up or other errors. When I'd click an IMAP folder it would just show whitespace and never pull up the emails. auth_worker_max_count = # Number of authentication processes to create count = This is an extremely low volume host, and I'm an efficiency freak. I don't like having "unnecessary" processes running if it is at all possible to avoid it. Given my IMAP user load, I know for a fact that I should only need one auth process, and for that matter, given my load, running all the dovecot processes from inetd is even a valid option, although I've not yet attempted that. Any ideas? Thanks. -- Stan

[Dovecot] dovecot and firstname.initial.lastname mbox format archive
by Wilko Bulte 19 Feb '10

19 Feb '10

hi Today I have been in a puzzling fight with 2 dovecot versions that I would like to ask some comments on. The situation is this: - I have a considerable mail archive in mbox format (yes, I know, but that is what I have..). - My mail reader is mutt 1.5.20 by the way. - Some of these mbox files have names like firstname.initial.lastname Note the . seperating the parts of the email-ers name. - On my old system I have dovecot v 1.1.7 which has always worked flawless - On my new system I have dovecot v 1.2.8 which refuses to handle these dot-seperated files. I get the somewhat familiar "Mailbox doesn't allow inferior mailboxes". On a not-previously-existing mbox dovecot 1.2.8 produces the directory hierarchy thing: firstname -> initial -> lastname - I am using the same dovecot.conf on v.1.1.7 and v.1.2.8 Can anyone tell me if v1.2.8 no longer is able to do what v1.1.7 did? And what I dearly would like to get working :-( And if it can, what should I put in dovecot.conf to make that happen? thanks, Wilko -- wilko(a)FreeBSD.org

[Dovecot] 2nd REPOST: mbox vs maildir
by Ashley M. Kirchner 18 Feb '10

18 Feb '10

I'm going to assume this is just not possible, or that no one has an answer, which would lead me back to uw-imap since it does work as-is. So I'll post it again, hoping that there is a solution for this setup and that folks have just been too busy to help think about it and/or help come up with a possible solution. ----- Ignoring my previous message just for a second, I realized that my config wasn't correct. First the layout: ~mail/ ~mail/Drafts ~mail/Ashley-Feb09 ~mail/Others-Feb09 ~mail-Archives/ ~mail-Archives/2009/ ~mail-Archives/2009/Ashley/ ~mail-Archives/2009/Ashley/Ashley-Dec09 ~mail-Archives/2009/Ashley/Ashley-Nov09 ~mail-Archives/2009/Ashley/Ashley-Oct09 So I (now) have this for namespaces: namespace private { separator = / prefix = "mail/" location = mbox:~/mail:INBOX=/var/mail/%u inbox = yes hidden = no list = yes # for v1.1+ } namespace private { separator = / prefix = "mail-Archives/" location = maildir:~/mail-Archives:LAYOUT=fs inbox = no hidden = no list = yes subscriptions = yes } But when I'm in Thunderbird and I try to subscribe to anything that falls inside of ~/mail-Archives/ it won't work. I can browser all the way down to the folder, but I can't see anything within that folder. For example, consider the full path to the following 'Ashley-Dec09' mailbox: ~mail-Archives/2009/Ashley/Ashley-Dec09 In Thunderbird, when I hit 'Subscribe' I can browse down to '2009' and I can see 'Ashley', but I can't drill down into it and subscribe to 'Ashley-Jan09'. What am I missing here?

[Dovecot] LDAP as password database - some problems / suggestions
by Stefan Palme 18 Feb '10

18 Feb '10

Hi all, Using dovecot-1.2.6, I use dovecot with an LDAP backend for user authentication. In general this works ok, but I have some issues with this... In LDAP, I have users like this: dn:cn=user1,ou=users,dc=kapott,dc=org dn:cn=user2,ou=users,dc=kapott,dc=org etc. When authenticating users, I explicitely want to use the AUTH_BIND feature (and NOT lookup passwords). My problem: not ALL users from the LDAP system should be allowed to use the IMAP server. Currently, I have defined an auth_bind_userdn of "cn=%u,ou=users,dc=kapott,dc=org" in dovecot-ldap.conf, but with this, user1 AND user2 could login (but I don't want user2 to be able to use dovecot). Because the LDAP system is used in a larger environment, it is NOT possible to re-arrange the users like this: cn=user1,ou=dovecot,ou=users,dc=kapott,dc=org cn=user2,ou=not_dovecot,ou=users,dc=kapott,dc=org So my question: are there any plans to support group-based LDAP authentication? For several other application, I have something like this: dn:cn=dovecot,ou=groups,dc=kapott,dc=org objectclass:groupOfNames member:cn=user1,ou=users,dc=kapott,dc=org So I can define groups of user accounts - one group per application. A nice solution for this in dovecot would be, if I could "mix" password lookup and authentication bind: First, a search query should be used to find a valid DN to bind as. In my case, the search query could look like this: base="ou=groups,dc=kapott.org" filter="(&(cn=dovecot)(member=cn=%u,ou=users,dc=kapott,dc=org))" result_attribute="member" After finding a DN this way (via attribute "member"), I want to use auth_bind to use this DN for password verification... Any hints how to solve this? Any plans to support this in the future? Thanks and regards -stefan-

[Dovecot] Courier->Dovecot Migration Issue
by Tony Rutherford 18 Feb '10

18 Feb '10

For testing purposes, on a small set of users, we've run the courier-dovecot-migrate.pl script. We are converting from Courier 0.43 to Dovecot 1.2.9. For the most part, things seem to be ok. However, an iPhone IMAP client user is reporting a problem where some of her messages don't show up. Even stranger is the fact that these same messages do appear when using Outlook 2k7 for instance. The common denominator for when the messages are missing seems to be whether or not the message appeared in both the Courier IMAP and Courier POP3 uid files. The missing messages appear in the CourierIMAP file, but NOT the Courier POP file. Here is a snippet from the resulting Dovecot-uidlist file: 3 V1141844265 N12392 9338 P00cf2eb6_fadc_4992_ad3a_57cc83a16eab W5146 :00cf2eb6_fadc_4992_ad3a_57cc83a16eab:2,S 9788 P0b18a2d6_97dd_4712_a09c_23c7a3d59467 W4055 :0b18a2d6_97dd_4712_a09c_23c7a3d59467:2,S 9942 P0b3cfd0b_1fc7_47b3_805f_b369a3bb6c65 W4359 :0b3cfd0b_1fc7_47b3_805f_b369a3bb6c65:2,S 10100 Pe178f1ed_d648_47e8_807a_3e2d655d7f84 W12028 :e178f1ed_d648_47e8_807a_3e2d655d7f84:2,S 10101 Pe3f28a53_a4d4_4f3d_babe_5df72bc35b47 W13974 :e3f28a53_a4d4_4f3d_babe_5df72bc35b47:2,S 10102 Pf3c3024b_2850_43ef_a397_d5cae5c8f537 W7177 :f3c3024b_2850_43ef_a397_d5cae5c8f537:2,S 10104 P6e808a68_0a7b_4528_aa67_4cc16361c56b W10817 :6e808a68_0a7b_4528_aa67_4cc16361c56b:2,S 10105 P65c8218d_7b2a_43b7_82a4_2743025bd954 W3579 :65c8218d_7b2a_43b7_82a4_2743025bd954:2,S 10106 P963cc43e_0355_481e_99d5_5468708bc28f W6410 :963cc43e_0355_481e_99d5_5468708bc28f:2,S 10107 P1405aefc_b98b_4a35_a7dd_a69199f724d0 W4703 :1405aefc_b98b_4a35_a7dd_a69199f724d0:2,S 10108 P67908fad_ec0a_4786_b0f1_c7cfaa23d09a W127288 :67908fad_ec0a_4786_b0f1_c7cfaa23d09a:2,S 10109 :9176f3b2_1927_4657_baa8_bfe4c39e89d4:2,S 10110 :79047185_aef7_48ec_aff2_6b71bd566acd:2,S 10111 :efe275a0_a7a8_4f47_b638_45a18bc0b108:2,S The last three entries exist in the Courier IMAP file, but NOT the Courier POP file. The resulting dovecot-uidlist format is different, but to be honest, I haven't been able to find the exact specification for the format of the dovecot-uidlist file (if it exists). What is really strange to me is: If there was a problem with the migration script and resulting dovecot-uidlist file, why would these messages show up fine in some client (ex. Outlook) and not others (ex. iPhone). Regards, Tony

[Dovecot] Virtual mailboxes show up twice
by Matthijs Kooijman 18 Feb '10

18 Feb '10

Hi all, I've been struggling a bit getting Hastymail webmail to work with my virtual mailboxes. After a while, I discovered that my virtual mailboxes are listed twice: Once with \NoSelect and once without. See the following (partial) LIST reponse: * LIST (\Noselect \HasChildren) "/" "virtual" * LIST (\Noselect \HasNoChildren) "/" "virtual/foo" ... * LIST (\HasNoChildren) "/" "virtual/foo" This makes somewhat sense, since my "virtual" namespace is a subdir of my default namespace: mail_location = Maildir:~/Mail:LAYOUT=fs # Default namespace, uses mail_location above namespace private { prefix = separator = / inbox = yes } # Virtual mailboxes namespace private { prefix = virtual/ separator = / # Store virtual mailbox in a "virtual" subdirectory. We use the fs layout, # so nesting of mailboxes is done using normal filesystem nesting. location = virtual:~/Mail/virtual:LAYOUT=fs } Now, should dovecot handle this configuration transparently by hiding the virtual directory from the default namespace, or is this configuration just not supported and should the virtual directory be outside of ~/Mail? The current wiki documentation on the virtual plugin currently does suggest this configuration, its examples point to ~/Maildir/virtual. Gr. Matthijs

[Dovecot] configuring overquota message

[Dovecot] Problem in sharing mailboxes across users
by Rampage 18 Feb '10

18 Feb '10

Hello everyone, I'm trying to configure dovecot to allow users to share their imap folders. I've followed the wiki and i'm near to accomplish my tasks, when i set ACL properly on folders using imap commands the other user can see the folder as shared, but i can't subscribe to it or even access its content using any email client (like thunderbird) couse it looks like the path to the shared folder is not complete. i mean when i go to "manage subscriptions" i can see the shared folder from the other users as "shared/user@domain/sharedfoldername" but since only "sharedfoldername" is present i cant subscribe to it. am i missing somethimg? like do i need to setup a particular directory tree on the filesystem? thnx in advice for your help. Best regards. Francesco.

[Dovecot] Problem with allow_nets passdb parameter and Postfix
by Неворотин Вадим 18 Feb '10

18 Feb '10

I use Dovecot for SASL authentication from Postfix. In Postfix main.cf I have: smtpd_sasl_type = dovecot It works good, but now I need to allow users to connect by IMAP only from given IP adresses. I've added extra field allow_nets to passdb in Dovecot, and IMAP authentication works fine. But now I can't connect to my SMTP server because when smtpd ask dovecot about user authentification, dovecot always denied it. Even if I try to connect to SMTP from correct IP, listed in allow_nets for user. In dovecot log I have messages about incorrect ip like this: dovecot: 2010-02-15 13:28:51 Info: auth(default): passwd-file(malamut): lookup: user=malamut file=/etc/dovecot/temp.users dovecot: 2010-02-15 13:28:51 Info: auth(default): passdb(malamut): allow_nets check failed: Remote IP not known dovecot: 2010-02-15 13:28:53 Info: auth(default): client out: FAIL 7 user=malamut Problem is clear: smtpd don't send client IP to dovecot authentication socket. But I need to limit the ability of connection to users only from specific IP. Both for SMTP and IMAP. How can I do that? I use dovecot 1.0.15 and Postfix 2.5.5 on Debian Lenny.

[Dovecot] quick question
by David Halik 18 Feb '10

18 Feb '10

Timo (and anyone else who feels like chiming in), I was just wondering if you'd be able to tell me if the amount of corruption I see on a daily basis is what you consider "average" for our current setup and traffic. Now that we are no longer experiencing any core dumps with the latest patches since our migration from courier two months ago, I'd like to know what is expected as operational norms. Prior to this we had never used Dovecot, so I have nothing to go on. Our physical setup is 10 Centos 5.4 x86_64 IMAP/POP servers, all with the same NFS backend where the index, control, and Maildir's for the users reside. Accessing this are direct connections from clients, plus multiple squirrelmail webservers, and pine users, all at the same time with layer4 switch connection load balancing. Each server has an average of about 400 connections, for a total of around concurrent 4000 during a normal business day. This is out of a possible user population of about 15,000. All our dovecot servers syslog to one machine, and on average I see about 50-75 instances of file corruption per day. I'm not counting each line, since some instances of corruption generate a log message for each uid that's wrong. This is just me counting "user A was corrupted once at 10:00, user B was corrupted at 10:25" for example. Examples of the corruption are as follows: ########### Corrupted transaction log file ..../dovecot/.INBOX/dovecot.index.log seq 28: Invalid transaction log size (32692 vs 32800): ...../dovecot/.INBOX/dovecot.index.log (sync_offset=32692) Corrupted index cache file ...../dovecot/.Sent Messages/dovecot.index.cache: Corrupted physical size for uid=624: 0 != 53490263 Corrupted transaction log file ..../dovecot/.INBOX/dovecot.index.log seq 66: Unexpected garbage at EOF (sync_offset=21608) Corrupted transaction log file ...../dovecot/.Trash.RFA/dovecot.index.log seq 2: indexid changed 1264098644 -> 1264098664 (sync_offset=0) Corrupted index cache file ...../dovecot/.INBOX/dovecot.index.cache: invalid record size Corrupted index cache file ...../dovecot/.INBOX/dovecot.index.cache: field index too large (33 >= 19) Corrupted transaction log file ..../dovecot/.INBOX/dovecot.index.log seq 40: record size too small (type=0x0, offset=5788, size=0) (sync_offset=5812) ########## These are most of the unique messages I could find, although the majority are the same as the first two I posted. So, my question, is this normal for a setup such as ours? I've been arguing with my boss over this since the switch. My opinion is that with a setup such as ours where a user can be logged in using Thunderbird, Squirrelmail, and their Blackberry all concurrently at the same time, there will always be the occasional index/log corruption. Unfortunately, he is of the opinion that there should rarely be any and there is a design flaw in how Dovecot is designed to work with multiple services with an NFS backend. What has been your experience so far?

[Dovecot] dovecot-sieve vacation vs qmail-ldap
by Lazy 18 Feb '10

18 Feb '10

Helloo, We are using dovectot lda with qmail-ldap, dovecot 1.2.10, sieve 0.1.15 lda is executed as exec /var/qmail/bin/preline -f /usr/local/dovecot/libexec/dovecot/deliver -s preline adds Delivered-To: header, everything works fine except vacation Feb 9 16:07:16 thebe dovecot: deliver(lazy): sieve: msgid=unspecified: discarding vacation response for message implicitly delivered to <lazy(a)thebe.org> Feb 9 16:07:16 thebe dovecot: deliver(lazy): sieve: msgid=unspecified: stored mail into mailbox 'INBOX' thebe.org is the hostname of the machine, oryginal recipient address has other domain .dovecot.sieve file looks like this require ["vacation"]; #autoresponder vacation :days 1 :subject "Auto Reply / Odpowiedz automatyczna" "aaaaaaaaaaaaaaaaaaaaa"; I did experiments with :addresses ["*"] without any luck. deliver only gets user and HOME directory form env variables provided by qmail, so it's unaware of the target email address. How to fix it ? I was thinking about deliver extracting target address from Delivered-To: header added by qmail's preline, or use DTLINE env variable, whitch qmail populates with Delivered-To header.

[Dovecot] using signed certificates for TLS/SSL
by Leonardo Rodrigues 18 Feb '10

18 Feb '10

Hi, I have, in one customer, a web server running on a Verisign-signed certificate SSL certificate. Everything works fine, IE and Firefox connects on https without asking anything, which usually happens on self-signed certificates. I'm trying to use that certificate on dovecot, but clients (Thunderbird basically) keeps saying the certificate is not valid. yes i'm using, when configuring Thunderbird, the same CN that was signed by Verisign for the web usage i've enabled verbose_ssl and got when thunderbird tries to connect: Feb 18 12:32:02 correio dovecot: imap-login: Disconnected (no auth attempts): rip=201.86.xxx.xxx, lip=192.168.1.2, TLS handshaking: SSL_accept() failed: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca unknown CA ??? is that Thunderbird that is not recognizing the Verisign-signed certificate ? Do i need to, somehow, install some Verisign CA certificate in dovecot.conf ? when using a self-signed certificate, i also get an SSL_accept failed, but with different message: Feb 18 12:41:45 correio dovecot: imap-login: Disconnected (no auth attempts): rip=201.86.191.114, lip=192.168.1.2, TLS handshaking: SSL_accept() failed: error:14094412:SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate despite the fact my certificates were generated for use with Apache, i can 'print' them, both of them, with the same commands i use to print dovecot generated certificates, with mkcert.sh. So, it seems they are compatible. if i click OK on Thunderbird, when using my Verisign-signed certificates, everything works and i do got TLS logs: Feb 18 12:23:36 correio dovecot: imap-login: Login: user=<user(a)domain.com.br>, method=PLAIN, rip=201.86.xx.xx, lip=192.168.1.2, TLS, TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits) Feb 18 12:31:43 correio dovecot: imap-login: Login: user=<user(a)domain.com.br>, method=PLAIN, rip=201.86.xx.xx, lip=192.168.1.2, TLS, TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits) what am i doing wrong ?? or using a signed-certificate for WEB usage is not possible on dovecot ? -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

[Dovecot] revision control on maildir possible?
by Markus Beyer 18 Feb '10

18 Feb '10

Hi, I was wondering if it is possible to put a dovecot managed maildir under a vcs like system, for example git or bzr. I'd like to have a seamless history of all mail going in and out of my mailboxes, so a vcs like system seams a good choice for me. I'm not quite sure however if that would cause any problems to dovecot and what the best way of handling commits would be. If anyone on the list got any pointers regarding this, it would be much apprechiated. Best regards, Markus -- Sicherer, schneller und einfacher.

[Dovecot] tls not working on ubuntu
by zhong ming wu 18 Feb '10

18 Feb '10

Hello List, I'm new to dovecot. I have sucessfully configured dovecot with just virtual users on a centos linux box to my satisfaction; I can connect with TLS with disable_plaintext_auth = yes. This dovecot is also version > 1. Can't post exact version right now but it's what comes with Centos 5.4. On a Ubuntu 9.10 box here, I cannot connect with TLS (port 110) but I can connect with plain SSL (port 995). The config files between centos and ubuntu boxes are the same except for minor details. The following is the log entry Feb 17 21:38:18 ubuntu dovecot: pop3-login: Disconnected (no auth attempts): rip=192.168.0.101, lip=192.168.0.108 The output below is from a binary compiled from source. I have also tested with 1.1.11 (that I get from apt-get install) with the same config file. I have tested ubuntu with both Thunderbird 3 and thunderbird 2. I have also searched google as well as dovecot website.

[Dovecot] Special user
by Daniel L. Miller 17 Feb '10

17 Feb '10

Not sure what to call this - I'm actually working out the details as I type this. I want to have a valid username/password for an account for sending purposes - but when receiving this is an alias that broadcasts to several users. Example: accountspayable(a)mydomain.com - is an alias for jane(a)mydomain.com, june(a)mydomain.com, and john(a)mydomain.com. However - any mails sent (from a particular client software) should all only show "accountspayable" as the sender. How would I implement this? I'm asking here because Dovecot serves as the authentication mechanism for my SMTP server (Postfix) via LDAP lookups. -- Daniel

[Dovecot] salted passwords
by Leonardo Rodrigues 17 Feb '10

17 Feb '10

The idea of salted hash algorithms is to generate a different hash even if the same text is entered. That can be easily seen with dovecotpw: using NON-salted SHA256, same hash is generated for a given password [root@correio ~]# dovecotpw -s SHA256 -p 123 {SHA256}pmWkWSBCL51Bfkhn79xPuKBKHz//H6B+mY6G9/eieuM= [root@correio ~]# dovecotpw -s SHA256 -p 123 {SHA256}pmWkWSBCL51Bfkhn79xPuKBKHz//H6B+mY6G9/eieuM= [root@correio ~]# dovecotpw -s SHA256 -p 123 {SHA256}pmWkWSBCL51Bfkhn79xPuKBKHz//H6B+mY6G9/eieuM= [root@correio ~]# using SALTED SHA256, a different hash is generated for the same given password [root@correio ~]# dovecotpw -s SSHA256 -p 123 {SSHA256}FpJZqafpEVKp2heepp9Z7+OeHaX+DBVpLzd6GKg3BW1XqDS0 [root@correio ~]# dovecotpw -s SSHA256 -p 123 {SSHA256}6lWmvtO3SKG5RMET5n89WMIp0xeCg3U14xH1xnAXbvkr8Yjk [root@correio ~]# dovecotpw -s SSHA256 -p 123 {SSHA256}7fXVjC7Iiu0Ko9SgyBpbDvbwMSkoxMILRjDUE0nNpCHBFaIa [root@correio ~]# This ideia is OK to me ... but i'm having a hard time trying to figure out how my dovecot-sql.conf would be in the case i store salted SHA256 passwords on the database. The idea is to use a RANDOM salt, not a fixed one, just like dovecotpw does. would it be as simple as changing the 'password', which today is plaintext, by something like concat('{SHA256}',password) ??? dont i have to give the salt, somehow ?? Or should i store the salt used in the password, for example first or last N characters .... is there anyone using dovecot with MySQL and SSHA256 passwords that can share me the dovecot-sql.conf file ? -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

Your results are even more impressive if that's the case. Sorry if it's less impressive, but I've certainly configured the VM for 4 cores. The cores are shared equally between all VMs, I've done no prioritization because I've not had any performance issues related to resource contention. Having 10x15k RPM spindles to seek across, and 512MB of cache on the controller, means I can give Postfix/Amavis/Dovecot 3GB of RAM to use, and 1GB of it is always used for cache, without ever dipping into swap. I get occasional spikes to 30ms of disk latency, but it stays below 5ms for most of the workday. > Also, are you seeing the classic system clock drift of ESX guests, > and if so, is it causing problems with smtp and imap? Not at all, that's what the VMware tools are for. The ESXi host is configured to use our NTP server inside the VPN, and the VMware tools package synchronizes the guest clock with the host. I ran into this on our webmail client as well, then I discovered how easy it really is to install the VMware tools on Ubuntu, so it's no longer a problem. Don't want to stray off topic, so I'll start a new thread, but I'm now attempting to bring High Availability to the mix, and could use some suggestions. -- Wayne Thursby System Administrator Physicians Group, LLC

[Dovecot] sieve addflag has stopped working
by Andrew Schulman 16 Feb '10

16 Feb '10

Dovecot 1.2.10 in Debian, using Dovecot sieve. I have a sieve script, generated by Ingo, that's supposed to mark spam messages as "Seen" and file them into the Junk folder. In part it reads: require ["regex", "body", "imapflags", "fileinto"]; if exists "X-Spam-Flag" { addflag "\\Seen"; fileinto "Junk"; removeflag "\\Seen"; stop; } This has been working correctly for a long time, but since about 2 weeks ago now, the "Seen" flag isn't being set, although the messages are still being filed into the Junk folder. In two different mail clients, new messages in the Junk folder show up as being unread. Looking at the mail files that hold those messages, the file names don't have an "S" flag appended, while older messages all have the "S" and show up as already seen in the mail clients. I don't believe that I've updated dovecot recently, so I'm not sure why the behavior has changed. Note that I do have plugin { sieve_extensions = +imapflags } in dovecot.conf. I know that imapflags is deprecated, but it is still supposed to be supported. Unfortunately ingo1 doesn't support imap4flags yet (http://bugs.horde.org/ticket/8784) I'm trying to find log information that might indicate an error, but I'm not finding much. /var/log/exim4/mainlog just says: 2010-02-15 14:22:14 1Nh6WK-000200-8z <xxx(a)xxx.xxx>: deliver_pipe transport output: deliver(andrex): Info: sieve: msgid=<ad58db2a42700ec0e5c924c8882d48c2(a)yourmailnews.net>: stored mail into mailbox 'Junk' The wiki says that there should be a log file ~/.dovecot.sieve.log, but there isn't one, which I guess means there are no error messages.

[Dovecot] Dovecot+Postfix+Maildir with ActiveDirectory userbase
by Wayne Thursby 15 Feb '10

15 Feb '10

> Luigi Rosa <lists(a)luigirosa.com> uttered: > Hi, > has anyone implemented a mail server with maildir, Postfix and Dovecot > using > Active Directory ad userbase and password authentication? > > Do I need Samba to authenticate users? > > Can I use credential caching just like mysql? > > > Ciao, > luigi > > -- > / > +--[Luigi Rosa]-- > \ Hi Luigi, I am running a Postfix/Dovecot setup that is authenticating against a Windows 2000 domain. It is possible to authenticate several different ways, including Kerberos/Winbind and NTLM via Samba. I used the following article as a guide. It is for FreeBSD, but the configuration instructions apply equally to any Postfix/Dovecot setup. I am running mine on Ubuntu 8.10. http://blog.al-shami.net/index.php/freebsd-postfix-dovecot-and-active-direc… The above article covers most of the setup, however I have changed a few things for my purposes. In short, I am using LDAP to communicate with the Active Directory server. I am looking up email addresses and aliases from AD in Postfix and using Dovecot as LDA. Postfix uses Dovecot's SASL for authentication, and Dovecot in turn authenticates against AD. My Setup: Postfix and Dovecot running on the same virtual machine on a Dell 2950 with 1x Xeon E5440 on ESXi 4. Maildirs served up by 10x146GB SCSI drives on RAID-10 via direct attached Dell MD-1000. Serving 600+ users, mailbox sizes up to 14GiB with constant heavy searching (no fts yet) and filtering (sieve and IMAP clients). 80,000 messages delivered per week, 95,000 messages rejected, 17,000 spam. 15 minute Load average stays under .50 all day with 4 CPU cores. IMAP clients include Outlook 2007, Thunderbird 2 and 3, in addition to webmail via Group Office (yuck). dovecot-ldap.conf: # Include multiple domain controllers for redundancy, first one is # at the same facility as the Dovecot server. hosts = 10.0.1.12:389 10.0.2.12:389 10.0.3.12:389 # Specify the full DN of a user to authenticate against dn = cn=Internal, ou=People, dc=example, dc=com dnpass = some_secure_password auth_bind = yes ldap_version = 3 base = ou=People, dc=example, dc=com # Specify the base storage for email here user_attrs = sAMAccountName=home=/var/vmail/example.com/%$ # The following user_filter should all be on a single line. # The ugly userAccountControl param means "Exclude disabled users" user_filter = (&(sAMAccountName=%Ln)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) pass_filter = (&(sAMAccountName=%Ln)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) For the Postfix side of things, the article explains how to set Postfix to use Dovecot's SASL for authentication. It also specifies separate confs for Postfix to lookup users and aliases from. For my purposes, I decided not to modify the AD schema, and to instead utilize an unused field to store aliases in. This field had to be able to store multiple values in a way that I could query easily via LDAP. I chose the "IP Phone" field for this purpose. In the AD GUI it is easily accessible, and allows for multiple values to be stored. Note its usage in the queries that follow. /etc/postfix/ldap-users.cf: # Same list of DCs as in dovecot-ldap.conf server_host = ldap://10.0.1.12:389 ldap://10.0.2.12:389 ldap://10.0.3.12:389 search_base = dc=example, dc=com bind = yes bind_dn = EXAMPLE\internal bind_pw = a_secure_password # Use this lookup for email addresses matching the following domains # corresponds with virtal_mailbox_domains in main.cf domain = example.com, examplelegacy.com, exmple.com # The following query has been modified a bit from the above article. # First, the userAccountControl param specifies the exclusion of # disabled users. # The other change is from objectClass to objectCategory. query_filter = (&(&(objectCategory=person)(sAMAccountName=%u))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) result_attribute = sAMAccountName version = 3 # I was having trouble with referrals not resolving properly due to a # misconfigured domain controller. I turned this option off and have # not had a problem since. chase_referrals = no result_format=example.com/%s/ debuglevel = 0 timeout = 30 /etc/postfix/ldap-aliases.cf: # Same list of DCs as in dovecot-ldap.conf server_host = ldap://10.0.1.12:389 ldap://10.0.2.12:389 ldap://10.0.3.12:389 search_base = dc=example, dc=com bind = yes bind_dn = EXAMPLE\internal bind_pw = a_secure_password domain = example.com, examplelegacy.com, exmple.com # This query looks up aliases from the otherIPPhone field. query_filter = (&(&(objectCategory=person)(|(otherIPPhone=%u)(sAMAccountName=%u)))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) result_attribute = sAMAccountName version = 3 chase_referrals = no result_format=%s(a)example.com debuglevel = 0 timeout = 30 The objectCategory replacement for objectClass is a *huge* performance increase. objectClass is not indexed in Active Directory, forcing a lot of CPU cycles to be wasted for every lookup. The way I have implemented things, this means two of these expensive lookups per incoming email (even if it was undeliverable!). At first this was using around 50% CPU on a dual Xeon domain controller. This was acceptable at the time, but after my optimizations we were able to move authentication to a virtual machine with 640MB of RAM and a single CPU core where it now stays below 20% all day. Changing the lookup to an indexed field probably cut the initial load by 90%. Adding auth_cache settings to dovecot.conf then further reduced load by more than 50%. Well, I suppose that screed should suffice for my first post. I've gained much from just lurking in this list, just trying to contribute where I can. -- Wayne Thursby System Administrator Physicians Group, LLC

Well I've looked forward into the wiki and did not found my server have only system users ( no virtual domain ) and the wiki says : System users If you wish you use deliver for all system users on a single domain mail host you can do it by editing mailbox_command parameter in /etc/postfix/main.cf (postconf(5)): That's what I did but then I have this problem with DOTLOCK If I chmod 777 /var/mail directory it works but I do not feel comfortable with that kind of access rights ...

[Dovecot] Capability COMPRESS implemented?
by Ed W 15 Feb '10

15 Feb '10

Hi, I just read that http://tools.ietf.org/html/rfc4978 ..is being implemented in Thunderbird 3. This is great news! It's been a long time since we last discussed this and I don't think it's currently implemented in Dovecot, but since Cyrus just added it, any chance of getting support in Dovecot please? (Fastmail seems to be supporting this effort) On a similar note we had a previous thread about supporting TLS deflate - any chance you could investigate this again and add support on the Dovecot side so at least it would be feasible to submit a bug fix on the Thunderbird side? (It looked like a one liner change back when we last discussed it?) Thanks Ed W (Obviously for those looking for an external high performance compressor you can use our compressing email proxy from http://www.mailasail.com ...)

[Dovecot] So, what about clustering and load balancing?
by Stefan Foerster 15 Feb '10

15 Feb '10

Hello world, so, with beta2 of Dovecot 2.0 being available, what is the preferred way to achieve load balancing and fault tolerance? As far as I can see it, there are basically two options: 1) Use a HA shared storage, export either a cluster filesystem or NFS, and have your dovecot servers mount that file system. Load balance these servers (Cisco ACE, ldirectord, ...) and there you go. Overall performance is limited by the speed of the shared storage and may further decrease due to locking issues, imperformant cluster filesystems and so on. 2) Set up every dovecot server with local storage and trigger a dsync after each change (pyinotfiy, incron, parse LMTP delivery logs, ...). Load balance these servers as before. Depending on the number of syncs that have to be done, mailbox replication may lag behind. The need to constantly spawn dsync processes may further decrease performance if you don't do it right (stickiness of established connections, replicating at most every xyz seconds). What are your opinions on that matter? Stefan P.S: I've set up option two in a test setup, though the incron/inotify part is still giving me a headache.

[Dovecot] POP3 with dovecot LDA and sieve
by Arthur Titeica 14 Feb '10

14 Feb '10

Hello. I'm using Postfix with Dovecot as IMAP, POP3 and LDA. With sieve rules I successfully move mails to specific mailboxes and this is great if accessing the account thru IMAP. However, when accessing thru POP3 I only get mails from Inbox. I wonder if it's possible to get real new mails, regardless of the folder they're in. Thanks for any thoughts. Arthur

[Dovecot] Virtual plugin and user_query
by Arthur Titeica 14 Feb '10

14 Feb '10

Hello, As per a previous reply regarding POP3 I'm now trying to configure the virtual plugin. However I don't really understand how to modify the sql user_query to properly indicate inbox=yes. I created 3 namespaces as per wiki instructions and I've modified the password and user queries as bellow: password_query = \ SELECT email, password, login , concat('*:bytes=', quota) \ AS userdb_quota_rule, \ CASE '%s' WHEN 'pop3' THEN NULL ELSE 'yes' \ END AS namespace_1_inbox, \ CASE '%s' WHEN 'pop3' THEN 'yes' ELSE NULL \ END AS namespace_2_inbox \ FROM users \ WHERE email = '%u' AND login = 'active' user_query = SELECT \ concat('*:bytes=', quota) AS quota_rule, \ CASE '%s' WHEN 'pop3' THEN NULL ELSE 'yes' \ END AS namespace_1_inbox, \ CASE '%s' WHEN 'pop3' THEN 'yes' ELSE NULL \ END AS namespace_2_inbox \ FROM users \ WHERE email = '%u' After that all I get in the logs is: IMAP(arthur(a)psw.ro): Error: namespace configuration error: inbox=yes namespace missing IMAP(arthur(a)psw.ro): Fatal: Namespace initialization failed As I don't really understand those case sql queries is there something I should add in the mysql tables? Any thoughts will be greatly appreciated. Thanks!

[Dovecot] deliver and cloning file permissions
by Alexander 'Leo' Bergolth 14 Feb '10

14 Feb '10

Hi! I'd like to use deliver (dovecot-1.2.10) as LDA to deliver mails to my local users on my postfix-system. However, deliver tries to copy the filesystem permissions of the mail-spool-files to the user's index files, which doesn't work, since the files in /var/mail/ belong to the group 'mail'. Feb 13 00:21:19 leo-x61 dovecot: deliver(leo): fchown(/home/leo/mail/.imap/INBOX/dovecot.index.log.newlock, -1, 12(mail)) failed: Operation not permitted (egid=100(users), group based on /var/mail/leo) I know that dovecot tries to clone the mailbox permissions in order to support shared folders but it would be nice if there was an option to disable this (or to just try it and ignore the fchown error). I could manually change group ownership of all mailboxes from mail to each user's primary group or set the mailbox-modes to 0600 but I'd also have to do that for every new user. (Tools to create users like useradd from shadow-utils use hardcoded file modes and group ownership.) Is there any workaround?

[Dovecot] Plugin question
by Valery Gorbunov 14 Feb '10

14 Feb '10

Hi All I needs to write plugin which converting messages by replacing entier message by one of parts of this message. In another words I need show part of multipart message instead entire message. Stream substitution in *mail->v.get_stream()* function gives incorrect results because mail indexed and cached before. Therefore I should wrap email during indexing too. something like: ----- struct index_transaction_context * it; it->ibox->mail_vfuncs->get_stream = convert_get_stream; ----- Is it enough or idea to replace mail stream by another will don't work anyway? Could you suggest how to show one mail instead another in Dovecot environment? Thank you Valery Gorbunov

[Dovecot] scalability
by Jonathan Tripathy 13 Feb '10

13 Feb '10

Hi Folks, How scalable is dovecot. Do you think a machine with a dual core 2.8Ghz processor and 2GB of RAM would do a business with 600 users? This server will have a 100Mbps link to the net, however it will be access by the business using a couple of ADSL lines (Roughly 7Mbps each). This machine will also be running Postfix Your help is appreciated Cheers Jonny

[Dovecot] REPOST: mbox vs maildir

Ignoring my previous message just for a second, I realized that my config wasn't correct. First the layout: ~mail/ ~mail/Drafts ~mail/Ashley-Feb09 ~mail/Others-Feb09 ~mail-Archives/ ~mail-Archives/2009/ ~mail-Archives/2009/Ashley/ ~mail-Archives/2009/Ashley/Ashley-Dec09 ~mail-Archives/2009/Ashley/Ashley-Nov09 ~mail-Archives/2009/Ashley/Ashley-Oct09 So I (now) have this for namespaces: namespace private { separator = / prefix = "mail/" location = mbox:~/mail:INBOX=/var/mail/%u inbox = yes hidden = no list = yes # for v1.1+ } namespace private { separator = / prefix = "mail-Archives/" location = maildir:~/mail-Archives:LAYOUT=fs inbox = no hidden = no list = yes subscriptions = yes } But when I'm in Thunderbird and I try to subscribe to anything that falls inside of ~/mail-Archives/ it won't work. I can browser all the way down to the folder, but I can't see anything within that folder. For example, consider the full path to the following 'Ashley-Dec09' mailbox: ~mail-Archives/2009/Ashley/Ashley-Dec09 In Thunderbird, when I hit 'Subscribe' I can browse down to '2009' and I can see 'Ashley', but I can't drill down into it and subscribe to 'Ashley-Jan09'. What am I missing here?

I still think that one possibility could be a Sieve script that would discard messages based on a message-ID cache like the procmail recipe does. Does dovecot's deliver have some sort of message-ID cache that could be used to removed the duplicates?

[Dovecot] Dovecot + managesieve + Roundcube

Hello I've installed managesieve on my mailhub FreeBSD from dovecot-managesieve ports to let roundcube users build email filters. The filter are well created in the right directory but the filter seems inefficient ( it does not filter ;-) ) see below the result of the dovecot -n command Thanks for any info > mail# dovecot -n > # 1.2.10: /usr/local/etc/dovecot.conf > # OS: FreeBSD 7.2-RELEASE amd64 > log_path: /var/log/dovecot/dovecot.log > info_log_path: /var/log/dovecot/info.log > protocols: imap imaps pop3 pop3s managesieve > listen(default): * > listen(imap): * > listen(pop3): * > listen(managesieve): localhost:2000 > disable_plaintext_auth: no > login_dir: /var/run/dovecot/login > login_executable(default): /usr/local/libexec/dovecot/imap-login > login_executable(imap): /usr/local/libexec/dovecot/imap-login > login_executable(pop3): /usr/local/libexec/dovecot/pop3-login > login_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login > login_processes_count: 10 > login_max_processes_count: 256 > login_max_connections: 1024 > max_mail_processes: 4096 > verbose_proctitle: yes > mail_privileged_group: mail > mail_location: mbox:%h/:INBOX=/var/mail/%u > mail_executable(default): /usr/local/libexec/dovecot/imap > mail_executable(imap): /usr/local/libexec/dovecot/imap > mail_executable(pop3): /usr/local/libexec/dovecot/pop3 > mail_executable(managesieve): /usr/local/libexec/dovecot/managesieve > mail_plugin_dir(default): /usr/local/lib/dovecot/imap > mail_plugin_dir(imap): /usr/local/lib/dovecot/imap > mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 > mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve > imap_client_workarounds(default): outlook-idle tb-extra-mailbox-sep > imap_client_workarounds(imap): outlook-idle tb-extra-mailbox-sep > imap_client_workarounds(pop3): > imap_client_workarounds(managesieve): > pop3_uidl_format(default): %08Xu%08Xv > pop3_uidl_format(imap): %08Xu%08Xv > pop3_uidl_format(pop3): %08Xv%08Xu > pop3_uidl_format(managesieve): %08Xu%08Xv > managesieve_logout_format(default): bytes=%i/%o > managesieve_logout_format(imap): bytes=%i/%o > managesieve_logout_format(pop3): bytes=%i/%o > managesieve_logout_format(managesieve): bytes ( in=%i : out=%o ) > lda: > postmaster_address: postmaster(a)esiee.fr > auth default: > verbose: yes > worker_max_count: 50 > passdb: > driver: passwd > userdb: > driver: passwd > plugin: > sieve: ~/.dovecot.sieve > sieve_dir: ~/sieve

[Dovecot] apache2 mod_authn_dovecot
by Boris Manojlovic 11 Feb '10

11 Feb '10

Dear All, I have created apache2 module that allows web users to authenticate against dovecot auth daemon. It connect to dovecot authentication client socket. Currently implemented mechanism is plaintext PLAIN. Currently there are no plans to support any other as only thing that i have created in apache module is "Basic" auth. Source code can be downloaded from; http://github.com/bmanojlovic/mod_authn_dovecot or tagged version v0.1 from: http://github.com/bmanojlovic/mod_authn_dovecot/tarball/v0.1 Currently built RPMS can be downloaded from OpenSUSE build service URL: http://download.opensuse.org/repositories/home:/bmanojlovic/<Distribution of choice> Please comment or raise issues if you think it is useful or full of bugs :). Boris Manojlovic P.S. Very basic README - HOW TO is on this URL http://github.com/bmanojlovic/mod_authn_dovecot/blob/master/README

[Dovecot] upgrade 1.0.15-2.3+lenny1 to 1.2.9-1~bpo50+1
by Stan Hoeppner 11 Feb '10

11 Feb '10

System: Debian 5.0.4 Lenny Kernel: custom 2.6.31.1 built from kernel.org source Dovecot: 1.0.15-2.3+lenny1 Available: 1.2.9-1~bpo50+1 Mailbox format: mbox Storage location: /home/$user/mail/ on ext2 fs Delivery: Postfix 2.5.5 local to /var/mail/$user As you can see Debian has a backport package of Dovecot 1.2.9 available to Lenny users, and it appears it is a big jump forward in terms of elapsed time and codebase. Debian ships Dovecot in a collection of 6 packages. I currently only use two, dovecot-common and dovecot-imapd. I'm guessing it would probably be wise to shutdown all my current Dovecot processes before starting the upgrade. Before I do this upgrade I figured I'd ask first to see if there are any gotchas or explosions awaiting me. Any warnings, hints, pointers anyone? Timo? Thanks. -- Stan

[Dovecot] fts squat -> webmail, fastcgi timeout: SOLR the answer?
by mailinglists＠belfin.ch 10 Feb '10

10 Feb '10

Hi I turned on fts squat to speed up full text searches over webmail. This works absolutely fantastic once the mailboxes are indexed. But when they are indexed for the first time I'm getting a fastcgi timeout after 30 seconds resulting into a internal server error on the webserver. In the background the indexing job is getting finished after 80 seconds for a 25k emails, ~300MB mailbox. Does solr allow user-offline indexing (no user interaction needed to kick on indexing) ? And the other question is, is there any mail user agent that would support server-side full text indexing and not create own indexes? Thanks, Philipp

[Dovecot] Purging a large folder... anything I need to be careful of?
by Dave 10 Feb '10

10 Feb '10

I've got a large message folder (about 40G in 'cur') that I need to empty to a more reasonable size. Oddly, my Thunderbird e-mail client only sees about 2.4G of that, and has "looped" a few times. What I mean is, I thought someone was cleaning the folder out, but Thunderbird apparently was actually just looping back to 0 every 4 gigs and starting to count up again Ha. But that's a sidenote. So, since Thunderbird apparently is not seeing all of the messages, what is the safest way to delete the files straight from the 'cur' folder? IS that safe? Will I mess up any of the dovecot indexes in any way?? Dave

[Dovecot] mbox vs maildir
by Ashley M. Kirchner 10 Feb '10

10 Feb '10

Ignoring my previous message just for a second, I realized that my config wasn't correct. So I have this for namespaces: namespace private { separator = / prefix = "mail/" location = mbox:~/mail:INBOX=/var/mail/%u inbox = yes hidden = no list = yes # for v1.1+ } namespace private { separator = / prefix = "mail-Archives/" location = maildir:~/mail-Archives:LAYOUT=fs inbox = no hidden = no list = yes subscriptions = yes } But when I'm in Thunderbird and I try to subscribe to anything that falls inside of ~/mail-Archives/ it won't work. I can browser all the way down to the folder, but I can't see anything within that folder. For example, consider the full path to the following 'Ashley-09' mailbox: ~/mail-Archives/2009/Ashley/Ashley-Jan09 In Thunderbird, when I hit 'Subscribe' I can browse down to '2009' and I can see 'Ashley', but I can't drill down into it and subscribe to 'Ashley-Jan09'. What am I missing here?

[Dovecot] Folders within folders ...
by Ashley M. Kirchner 10 Feb '10

10 Feb '10

Our mail setup is as follows: ~/mail/ - This contains single mailboxes (Drafts, Trash, and others) ~/mail-Archives/ - This contains a hierarchy of folders containing mailboxes For example, a tree of ~/mail/ would look like this: ~/mail/ ~/mail/Trash ~/mail/Drafts ~/mail/sent-mail ~/mail/My Stuff ~/mail/Important ~/mail/test/SomeFolder <-- this would never happen, but I have to account for it during our transition A tree of ~/mail-Archives/ would look like this: ~mail-Archives/2009/MyStuff/MyStuff-Dec09 ~mail-Archives/2009/MyStuff/MyStuff-Nov09 ~mail-Archives/2009/MyStuff/MyStuff-Oct09 ~mail-Archives/2010/MyStuff/MyStuff-Jan10 ~mail-Archives/2010/Important/Important-Jan10 All of that works, I can open up Thunderbird and browser/read/delete messages no problem. However, when I try to move that 'test' folder from ~/mail/ into ~/mail-Archives I get an error message: 'Can't rename mailbox to another storage type.' The same thing happens if I try to move any of the mailboxes in ~/mail/ to ~/mail-Archives/ . Is there a way to fix that? Our namespaces look like this: namespace private { separator = / prefix = "mail/" location = mbox:~/mail:INBOX=/var/mail/%u inbox = yes hidden = no list = yes # for v1.1+ } namespace private { separator = / prefix = "mail-Archives/" location = mbox:~/mail-Archives inbox = no hidden = no list = yes subscriptions = yes }

[Dovecot] Dovecot and duplicates
by Veikko "Wexi" Skurnik 10 Feb '10

10 Feb '10

Hi I'm having a problem setting up duplicate filtering on my mail server. I've set up the mail server with Postfix and Dovecot with virtual LDAP users, ClamAV virus scanning. The problem is that some of the virtual users use multiple e-mail addresses and postfix delivers emails sent to a user as many times as the user has email address entries in LDAP. I was wondering what would be the smartest way to get rid of these duplicates, they have identical message ID:s and a simple procmail recipe does the trick, however as I'm using dovecots deliver, procmail isn't the answer. Is it possible to use Sieve to do this, I've been googling around *a lot* and haven't found anything that would solve the problem... This is the procmail recipe that succesfully eliminates the duplicates: MAILDIR=/var/vmail :0 Wh: msgid.lock | formail -D 8192 .msgid.cache Or could another solution be to configure postfix to first receive the email, then let procmail do the duplicate filtering, then ClamAV does the virus scan and finally dovecots deliver delivers the message to the virtual user's mailbox? Any help will be greatly appreciated =) Wexi -- * Veikko "Wexi" Skurnik: +358(44)5288338 * * wexi(a)wexin.net Wexi@IRCNet * * Näyttämönkatu 4 B 12 33720 Tampere * * "Kosminen balanssi ei saa järkkyä" *

[Dovecot] Converting layouts
by Luciano Mannucci 09 Feb '10

09 Feb '10

Hello, I'm using dovecot 1.2.10 with mbox format (which implies layout=fs) and I would like to switch to maildir++ layout without changing format in order to implement subfolders for IMAP users. I understand that I should move the INDEX location to avoid some namespace conflict (it would be a good idea anyway: I'll move them on another disc :). Now I have mail_location = mbox:/var/spool/mailboxes/%u:INBOX=/var/spool/mail/%u in my /etc/dovecot.conf. I think it should become somethink like mail_location=mbox:/var/spool/mailboxes/%u:LAYOUT=Maildir++:INBOX=/var/spool/mail/%u:INDEX=/var/dovecot_indexes I'll have to rename folders for IMAP users, right? Is there some script that does just that? Some other needed black magic for .subscriptions? Thanks to all in advance, Luciano. -- /"\ /Via A.

[Dovecot] Problem with created ~/mail directory
by Chris Adams 08 Feb '10

08 Feb '10

If a user doesn't have a ~/mail directory and logs in, the directory is created for them. However, it is created with insecure permissions, 0770 (full group access). The problem is this bit in src/lib-storage/index/mbox/mbox-storage.c: #define CREATE_MODE 0770 /* umask() should limit it more */ The code then uses CREATE_MODE as an argument to mkdir_parents(), but mkdir_parents() overrides the umask setting and forces the requested permissions. There's no way to override this except to change the source code. It looks like the same thing is in dbox-storage.c and cydir-storage.c. This is with Dovecot 1.2.10. -- Chris Adams <cmadams(a)hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.

[Dovecot] LMTP in 2.0: concurrency, inet sockets
by Stefan Foerster 07 Feb '10

07 Feb '10

I didn't really have much time to look at the beta versions of dovecot 2.0 (apart from installing it once and migrating most of my current configuration, purely for testing purposes). An exciting new feature is the LMTP support. In the default configuration I have seen, that one only listened on a Unix socket - will it support network (inet) sockets, too? What about concurrent deliviers? As of now, when using the deliver LDA together with Postfix, you have to make sure that only one recipient is passed to deliver at a time, so for multi-recipient mail, the system might spawn a large number of processes (two per recipient, therefore two forks/execve calls). Is that limit still imposed with the new LMTP server? Stefan

Hello, Occasionally (a few times a day) we get batches of Warnings in the log such as: dovecot: Warning: chdir(/maildir/x.co.uk/users/y) blocked for 18 secs This tends to last a minute or so for different users. /maildir is a NFS mount, and I'm suspecting it's the NFS server being busy and dovecot having to wait.

Hello list, I have found imap_allowed option in dovecot which do exactly what I need, for imap. Is there something similar for pop3 protocol?

Re: [Dovecot] mdbox compression
by Damon Atkins 06 Feb '10

06 Feb '10

ZFS has support for compression on the file system ( lzjb | gzip | gzip-N | zle ). gzip eats CPU even at levels as low as 3. From the zfs man page The lzjb compression algorithm is optimized for performance while providing decent data compression. You can specify the gzip level by using the value gzip-N where N is an integer from 1 (fastest) to 9 (best compression ratio). The cost of CPU to support compression (gzip) vs the Cost of Disk if mboxes are not compressed? The other interesting feature ZFS (OpenSolaris) has is de-duplication, it detects if the block which is about to be written, is the same as another block and instead of writing the block it puts a pointer to the already existing block, saving disk space. Only problem with this is you would need to filter out headers which are different even when the to/body is the same. Cheers

by Timo Sirainen 06 Feb '10

06 Feb '10

I was wondering if I should add compression support to mdbox one mail at a time or one file (~2MB) at a time. The tradeoffs are: * one mail at a time allows quickly seeking to wanted mail inside the file, but it can't compress mails as well * one file at a time compresses better, but seeking is slow because it can only be done by uncompressing all the data until the wanted offset is reached I did a quick test for this with 27 MB of my old INBOX mails: (note the -b option, so it doesn't count wasted fs space) mdbox/storage% du -sb . 15120350 . Maildir/cur% du -sb . 16517320 . % echo 1-15120350/16517320|bc -l .08457606924125705623 So, compressed mdboxes take 8.5% less space. This was with regular gzip compression with default level. With bzip2 -9 compression the difference was 10%. Any thoughts on if 8-10% is significant enough improvement to make seeking performance worse? Or perhaps I should just implement both ways.. :)

[Dovecot] Dovecote does'nt start - no log ?
by Jean-Francois 06 Feb '10

Hi All, Actually, I installed Dovecot on an OpenBSD server, however, after properly setting (assumed) the confs, Dovecot does'nt start. I don't know the reason but don't know how to debug. Where is the log about reason for not starting ? Thank you for helping. Regards

[Dovecot] Forcibly emptying a POP3 mailbox
by Răzvan Sandu 05 Feb '10

05 Feb '10

Hello, I've recently saw a discussion on this list, about a standardised way of emptying POP3 mailboxes on the server - but no solution came up. Please provide a suggestion for the following situation: - I am running a stock POP3 dovecot server, on Fedora 12 (dovecot version 1.2.9) - passwd-file authentication via /etc/imap.passwd - users are virtual, sharing the same UID/GID; - storage is in MailDir system; - for remote users, server is POP3-only, since the administrative policy says that every user should download his messages on the local workstation, then delete them from server immediately after succesful download. - IMAP is allowed only locally, in order to be used together via stock squirrelmail Web interface (for emergencies only) However, there are users that check the infamous „Leave a copy on the server” checkbox (or equivalent) in their mail clients, eventually adding „Delete messages after X days”. Since I have no direct administrative control on the clients, I absolutely need a way to forbid the above behaviour at server level, in order to enforce the policy. The server's HDD is meant to store received messages from reception to the first access only. Filesystem quotas are not an option in this scenario, since the UID/GID is the same for all virtual users. What I need is way to make sure that "cur" and "tmp" subdirectories are perfectly empty after the user downloads his mail. (I will also need a way to make sure that users using squirrelmail leave no populated "Sent" and "Trash" folders on server's HDD, but that's offtopic here). Could you please suggest a way to solve this ? Thanks a lot, Răzvan

Hello, Thanks a lot, but the problem here are not the IMAP users accessing the server via squirrelmail. Few people use this. What I mainly want to avoid are *POP3* users checking the „Leave a copy on the server” checkmark. I need a way of automatically performing the DELE command at server level, just after a POP3 user *succesfully* downloaded his messages via POP3... Thanks again, Răzvan

[Dovecot] postfix and dovecot on different systems - sasl request
by thomas polnik 05 Feb '10

05 Feb '10

Hello, until now I have use postfix and dovecot on the same server. Now I want/must split this both systems (server1 - postfix, server2 - dovecot). I used dovecot auth system for postfix ## snip ## smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth ## snap ## but this does not work, if dovecot is not running on the same server. I did not find any information in postfix/dovecot documentation, how I could solve this problem smart. My only idea, but it looks like quick and dirty solution: On the postfix system a small dovecot systems runs only for postfix sasl via /var/spool/postfix/private/auth. (Or I use saslauthd with sql or imap) The postfix system (on server 1) delivers mails via transport map to the dovecot system. On the dovecot system postfix delivers this mails i.e. via ## snip ## dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient} ## snip ## to the mail boxes. Are there other ways, how I could solve this problem? My wish configuration: postfix sends the auth request via tcp/ip to the dovecot auth system and not via a socket. I use postfix 2.6 and dovecot 1.2.6. Best regards, thomas polnik.

[Dovecot] dovecot-auth stops responding

Running dovecot 1.2.4(imap only) on AIX out of inetd. I accept passwords(PAM for auth) and kerberos tickets. Occasionally we see dovecot-auth stop responding.

[Dovecot] Fatal: chdir( ) failed: Permission denied
by Vallo Kallaste 05 Feb '10

05 Feb '10

Hi Dovecot fails to chdir() into users home directory giving the following error: Oct 9 16:43:49 jura dovecot: dovecot: Fatal: chdir(/a/home/mina) failed: Permission denied (euid=1118 0(mina) egid=11332(devel) missing +x perm: /a/home) Oct 9 16:43:49 jura dovecot: dovecot: child 14441 (imap) returned error 89 (Fatal failure) The reason seems to be that user primary group is "devel" and directory /a/home has ACL which gives execute permission only to the users in "domain users" group. Now the catch is that the user _is_ member of "domain users" group and is happily accessing his home directory over CIFS(Samba) for long time. Also, the user has no problem entering his home directory when using shell access. It just seems like the user lost membership of a bunch of supplementary groups. The group membership info is coming from M$ PDC via winbind and NSS. We have few users and can change the users primary group and/or relax the /a/home directory ACL, but overall this is not right. Shall I shut up or can we hope for a fix or at least explanation?

[Dovecot] Question re: storing non mail files via IMAP
by Charles Marcus 04 Feb '10

04 Feb '10

Hey Timo, I have a question regarding how dovecot might behave if a mail client (like, for example, Thunderbird) decided to store some of its config files on the IMAP server itself. Would there be a decent way of doing this with dovecot that wouldn't cause problems for other clients that didn't know about these files? Maybe there's a way to define a special folder that dovecot knows about at the top level of each users mail location that can be used for this kind of thing? All I'm thinking of are certain config related files, so they would be small, and would only be downloaded when they didn't already exist - ie, when someone adds their existing account to a new PC, the first time they logged in, TB could simply download all of the config files, restart itself, and voila, your pre-configured TB is ready to go...

[Dovecot] mailutil question re: translating mbox folders to maildir
by Stewart Dean 04 Feb '10

04 Feb '10

I need mailutil in order to use the mbox to maildir translation routines that are posted in the Dovecot wiki, but there is no mailutil with the AIX image... mailutil is apparently built as part of Pine, and indeed I can see it in the build tree from my V4.6.1 Pine build, which I still have....OTOH, my version of Pine is not patched for maildir. Will the native pine mailutil work with mb2md or does it have be a mailutil built in a patched Pine :) tree?

Only client knows, so only client may act. In that case, the only possibility is to have some automatic script that periodically "cleans" the "cur" subdirectories, as you suggested. However, not being a programmer at all, I'm far from being able to write an industrial-grade solution for this. ;-) Best regards, Răzvan

[Dovecot] Execute mailfilter after message move
by Kārlis Repsons 04 Feb '10

04 Feb '10

Hi, came here to ask, if there are any ideas about a possible Dovecot feature, which would allow execution of a specific mailfilter or other program after new message is *moved* in specified mail location? The practical benefit on my side would be, that there wouldn't be any need to do getmail cronjobs, which unnecessarily fill up logfiles... (primarily for easy spam learning and reporting)

[Dovecot] [dovecot] Problem with namespaces and dovecot -n

03 Feb '10

I'm running dovecot 2.0 revision 10622:de9d6dae7fe5 on AIX. I'm trying to see both namespaces that I have listed in mail.conf. namespace private { separator = / prefix = inbox = no hidden = no location = maildir:%h/Maildir list = yes } namespace private { separator = / prefix = "#mbox/" location = mbox:%h:INBOX=/var/mail/%u inbox = yes hidden = no list = yes # for v1.1+ } Whichever namespace is last, I can see when running dovecot -n. Am I supposed to only see the last one printed? # 2.0.beta2: /usr/local/dovecot2.0beta2/etc/dovecot/dovecot.conf # OS: AIX 3 0001112AD300 auth_debug = yes auth_gssapi_hostname = $ALL auth_krb5_keytab = /etc/krb5/dovecot.keytab auth_mechanisms = plain gssapi disable_plaintext_auth = no listen = * login_greeting = Dovecot version 2 on tr27n12 ready. mail_full_filesystem_access = yes mail_location = mbox:%h:INBOX=/var/spool/mail/%Ju/%u mbox_lazy_writes = no mbox_write_locks = fcntl mmap_disable = yes namespace { hidden = no inbox = yes list = yes location = mbox:%h:INBOX=/var/mail/%u prefix = #mbox/ separator = / name = private } passdb { deny = no driver = pam master = no pass = no } With this config I have no folders.

[Dovecot] [RFE] A way to encode passwords in the /etc/imap.passwd file
by Răzvan Sandu 03 Feb '10

03 Feb '10

Hello, Is this the proper place to suggest an enhancement for the stock dovecot package ? The enhancement would be the following: For the time being, the dovecotpw utility offers a standardised way to interactively encode a user password in a certain scheme, say: dovecotpw -s CRYPT Enter new passord: Re-enter new password: etc. Given a *valid* /etc/imap.passwd file (passwd-file authentication), dovecotpw should be able to process it non-interactively and output another text file with all {PLAIN} passwords converted in the specified <scheme>, i.e.: dovecotpwd -s CRYPT if=/etc/imap.passwd of=/etc/imap.passwd.converted where /etc/imap.passwd.converted have the previously {PLAIN} passwords converted in scheme CRYPT. Passwords that were previously encrypted in other schemes than {PLAIN} shoud remain untouched. That will allow quick securing of old legacy /etc/imap.passwd files. Thanks a lot, Răzvan

[Dovecot] disabling mail delivery for a user
by Frank Cusack 02 Feb '10

02 Feb '10

How can I disable mail delivery for a user yet still allow access to their mailbox from another account which their mail is shared to? If I put them in a userdb which has "deny = yes" that just disables their ability to login, yes? And they would still have mail delivered. I want to disable their ability to login AND bounce all mail delivered to them, preferably solely through dovecot configuration. I am using lda, obviously, for mail delivery. (I could configure the MTA to reject mail for them if there is no other option.)

[Dovecot] v2.0.beta2 released
by Timo Sirainen 02 Feb '10

02 Feb '10

http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta2.tar.gz http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta2.tar.gz.sig I tried to keep the configuration and APIs compatible with v2.0.beta1, but unfortunately there were a few things that really had to be changed: 1. passdbs and userdbs have now a separate "driver" setting inside them. So for example if you had: userdb passwd { } You'll now need to use instead: userdb { driver = passwd } 2. Services now have default inet_listeners. You need to either remove your existing ones, or override the defaults by giving the listeners's name like shown in the new example master.conf. For example if you had: service imap-login { inet_listener { port = 1234 .. change it to: service imap-login { inet_listener imap { port = 1234 If you want to disable a default listener, you can set its port to 0. Some new features: - Added auth_verbose_passwords = no|plain|sha1. If authentication fails, this setting logs the used password. If you don't really need to know what the password itself was, but are more interested in knowing if the user is simply trying to use the wrong password every single time or if it's a brute force attack, you can set this to "sha1" and only the SHA1 of the password is logged. That's enough to know if the password is same or different between login attempts. - lazy-expunge: Support a single-namespace configuration. In this setup if mailbox has some expunged messages and then the whole mailbox gets deleted, they get merged into the same deleted mailbox. - protocol !imap { .. } adds configuration to all protocols except imap. - imap/pop3 proxying supports now async DNS lookups for hosts. There's a separate dns-client service doing the lookups using OS's own blocking resolver. - dovecot-config file changed in a way that it'll be easier to create external software linking against dovecot libraries. This made Pigeonhole's configure script a lot simpler. And of course there have been lots of fixes.

[Dovecot] proxy_maybe regex
by David Halik 02 Feb '10

02 Feb '10

Does anyone know if dovecot support regex lookups for proxy/proxy_maybe, rather than mysql/ldap etc? I've been comparing it with perdition to see which one might be better for us to do layer7 username switching. Perdition supports the ability to not have any auth/db looks, but rather just a regex file that parses the usernames as they come in and forwards to the particular machine on the same port. For example: username:host ^[a-d]: 192.168.xxx.1 ^[e-k]: 192.168.xxx.2 and so on... I didn't think this was supported in dovecot, but I wanted to check first. I think this is going to end up being what we use to avoid NFS problems. It's lightweight, drops into our current setup, and doesn't require a mysql database which adds another point of failure. -- ================================ David Halik System Administrator OIT-CSS Rutgers University dhalik(a)jla.rutgers.edu ================================

[Dovecot] Want to have some users with Maildir, some with mbox

Want to have some users with Maildir, some with mbox, as I migrate from mbox format to maildir over the space of a month. After everyone is converted to maildir, I'll change the mail_location in dovecot.conf. During the interim, can I use the Custom mailbox location script (at the bottom of the Mail Location DC Wiki page)? > if [ -d $HOME/.maildir ]; then > export MAIL=maildir:$HOME/.maildir > else > export MAIL=mbox:$HOME/mail:INBOX=/var/mail/$USER > fi > Questions: 1) What does explicitly specifying MAIL this way override?

So would I change the above to: > if [ -d $HOME/Maildir ]; then > export MAIL=maildir:$HOME/Maildir:INDEX=/var/dcindx/$USER > else > export MAIL=mbox:$HOME/mail:INBOX=/var/spool/mail/$USER: > INDEX=/var/dcindx/$USER > fi Question 3: When converting existing users from mbox to maildir, should I delete the index contents?

[Dovecot] index location
by Dave Brenner 01 Feb '10

01 Feb '10

Greetings. We are testing with 1.2.9 and have found that with mail_full_filesystem_access set to 'yes', we cannot force indexes for folders under ~/mail to be stored in /var/dovecot/indexes/%u. /var/dovecot/indexes/%u/.imap/INBOX/dovecot.index* is created just fine, but everything else ends up in ~mail/.imap. If I change mail_full_filesystem_access to 'no', then all indexes are created in the expected location: $ ls -la /var/dovecot/indexes/blitz/ total 4 drwxr-xr-x 4 blitz popuser 512 Jan 25 11:46 . drwxrwxr-x 5 root popuser 512 Jan 22 16:16 .. drwxr-xr-x 3 blitz popuser 512 Jan 22 16:16 .imap drwxr-xr-x 3 blitz popuser 512 Jan 25 11:46 mail (I probably need to set the sticky bit for this, but for testing this is OK) We are setting the index location from /etc/passwd-dove: blitz:x:14267:500::/usr/users/dialups/blitz::userdb_mail=mbox:~/:INBOX=/var/mail/%u:INDEX=/var/dovecot/indexes/%u Is there a way to get this to function the way we'd like, with all indexes stored in /var/dovecot/indexes/u% ?

by Michael M. Slusarz 01 Feb '10

01 Feb '10

Not technically a bug, but a small waste of bandwidth: it seems (at least as of 1.2.10) that if neither CONDSTORE/QRESYNC are enabled dovecot still sends HIGHESTMODSEQ info: a examine Testing.AAA * FLAGS (\Answered \Flagged \Deleted \Seen \Draft $Forwarded impflag0 impflag1 impflag2) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 309 EXISTS * 0 RECENT * OK [UNSEEN 5] First unseen. * OK [UIDVALIDITY 1225053009] UIDs valid * OK [UIDNEXT 387] Predicted next UID * OK [HIGHESTMODSEQ 136] Highest a OK [READ-ONLY] Select completed. I'm guessing this would only happen if using a client that supports QRESYNC (like IMP) and then switching later to a client that doesn't support.

[Dovecot] Not understanding namespaces
by Stewart Dean 01 Feb '10

01 Feb '10

I have been diligently reading about namespace in the DC doc and what I can find in Google. Like the blind men and the elephant, I see the nature of some individual bits of namespace, some syntax and the overall purpose (overriding defaults and providing extensions), but I don't see the whole thing and how it is used. I am looking to do some maildir testing in what is a mbox default system, so I thought to employ namespace to do so. I see that namespace(s) can be defined in dovecot.conf and I see that it can be defined in TBird (under ServerSettings, Advanced Account Settings), but it isn't clear to me how they are made to work together. Some questions: - Is it that you can define multiple namespaces in dovecot.conf and then specify which of these you use in the TBird server settings? - What is the syntax of the TBird namespace specification? -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] sieve script
by Lampa 01 Feb '10

01 Feb '10

Hello, after qmail migration need convert some .procmailrc scripts. Found converter procmail -> sieve, but i'm not sure of quality of conversion. My script: --------------- if header :contains "from" ["user(a)domain1.tld", "user2(a)domain2.tld", "user3(a)domain3.tld"] { redirect "foo1(a)bar.tld"; redirect "foo2(a)bar.tld"; .... redirect "foo20(a)bar.tld"; } else { keep; } --------------- Converter script: --------------- require ["fileinto","regex","envelope","vacation"]; if envelope :comparator "i;octet" :contains "From.*(user@domain1.tld|user2@domain2.tld|user3@domain3.tld)" "" { redirect "foo1(a)bar.tld foo2(a)bar.tld .... foo20(a)bar.tld"; } if true { fileinto "$DEFAULT"; } --------------- Converter script is cannot be compiled. But it used other style envelope. So what is difference between envelope and header ? And there are some limits for redirect ? Thank you. -- Lampa

01 Feb '10

Hello, i'm trying to do some delivery notification for each incoming address. Problem is that sieve vacation has :days but minimum value is 1 eg period in which addresses are kept and are not responded to - but that is not that i want. Is there other extension (in devel ???) or some other way (lda using procmail or maildrop) how to implement my request ? (Before migration we used qmail + procmail). Thank you for your advices -- Lampa

[Dovecot] sha-512 ... shadow blended with database
by WJCarpenter 31 Jan '10

31 Jan '10

The cryptic subject is the outcome of my looking into how to do a particular thing. I wonder if anyone else has solved this problem in a way that hasn't occurred to me. I'm using dovecot 1.1.11 on Ubuntu Server 9.10. I could consider upgrading to my own install of a newer dovecot if it made a difference to this problem. I have two populations of dovecot users. Some users have Unix accounts (with logins disabled), and so their password hashes are stored in /etc/shadow. These days, the default configuration for that is salted SHA-512. It's easy for me to change that scheme to something else if I want to, but the important fact is that I already have some users with passwords in salted SHA-512. The other population of users is purely virtual, and their password hashes are stored in a MySQL database in SHA-1 format (unsalted, but moving to salted wouldn't be a big deal). The database also has a column identifying the hash scheme, so SHA-1 isn't some assumption. I know that I have have multiple passdb in my dovecot config, but I'm looking to unify my two user populations and put them all in the MySQL database. As far as I can tell from the wiki, there is no SHA-512 in any version of dovecot. MySQL also doesn't have SHA-512. So, I don't see a way of reworking my password checking to accomodate the salted SHA-512 values currently in /etc/shadow. I'd prefer to not ask the SHA-512 users to update their passwords for this administrative reason if I can avoid it (but so far, that looks like the only answer). Any ideas?

[Dovecot] LSUB output format != LIST output format
by Martin 31 Jan '10

31 Jan '10

Hi, I have a problem with my hanging claws-mail. I first subscribed to their bug tracker, described the problem and before I pressed on submit in their bugtracker, I realized it might be a problem with dovecot. I'm using dovecot for internal purposes only (catching all my external boxes and storing locally): # 1.2.8: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.2-RELEASE-p5 i386 listen: *, [::] ssl: required disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 1000 mail_privileged_group: mail mail_location: maildir:~/.mails imap_client_workarounds: delay-newmail netscape-eoh tb-extra-mailbox-sep lda: postmaster_address: postmaster(a)example.com sendmail_path: /usr/sbin/sendmail auth default: mechanisms: plain login username_format: %Lu passdb: driver: pam args: session=yes dovecot userdb: driver: passwd args: blocking=yes socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 384 The mailboxes are on simple UFS2 file system. Here is what I get when listing subscribed folders, like claws-mail does: . LSUB "" "*" * LSUB () "." "Trash" * LSUB () "." "Queue" * LSUB () "." "Sent" * LSUB () "." "Drafts" * LSUB () "."

"INBOX.Gentoo" * LSUB () "." "INBOX.Notifications" . OK Lsub completed. Please notice the "INBOX.FreeBSD." with the dot at the end of the folder name. Here the output of LIST: . LIST "" "*" * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Queue" * LIST (\HasNoChildren) "." "Sent" * LIST (\HasNoChildren) "." "Drafts" * LIST (\HasChildren) "."

"INBOX.Spam.LearnSpam" * LIST (\HasNoChildren) "." "INBOX.Gentoo" * LIST (\HasNoChildren) "." "INBOX.Steno" * LIST (\HasNoChildren) "." "INBOX.Notifications" . OK List completed. The folder name here does not have the dot at the end? Why is this happening? The RFC says the output should not differ, as far as I understood it. I think it might be the dot in LSUB causing claws-mail loop indefinitely when refreshing the folder structure. Annoying!! I hope, you can help me. Thanks in advance. -- Martin Sugioarto

[Dovecot] Recommended method?
by Brandon Lamb 30 Jan '10

30 Jan '10

Hopefully this isnt TOO general of a question. I have a raid server that runs dovecot and exports via nfs the maildir format store. I have 4 mail servers running exim that use dovecot to deliver over nfs I have been examing our entire setup and had the thought, would it be recommended to instead have another exim process running directly on the raid server and have my mail servers deliver mail to that rather than over nfs, if that makes sense? So mail would go from our postini frontend => mail cluster => final delivery via exim on raid server. Seems like this way I could make all the nfs config options go away and such. Thoughts?

[Dovecot] Pigeon hole sieve binaries and dovecot header install
by Mark Washenberger 30 Jan '10

30 Jan '10

Stephan, I've recently been playing around with packaging dovecot 2.0 and dovecot-2.0-pigeonhole, as well as the --enable-header-install configure options of both. This lead me to the following question. Should pigeonhole's sieve binaries rely on static libstorage / other dovecot libraries? It seems like they should instead use shared libraries, but I couldn't find a configure option to make this happen. That way, I could break my packages up like so: dovecot dovecot-devel libdovecot dovecot-pigeonhole dovecot-pigeonhole-devel And while pigeonhole/sieve might require libdovecot to run, it shouldn't require it to compile. Thoughts? I can provide a lot more detail about my compilation errors if you think its necessary.

[Dovecot] Does anyone know a good Dovecot hoster in europe?
by Johannes 30 Jan '10

30 Jan '10

Hi, though I am not sure this is the right place to ask, but I just try. I am looking for a better e-mail hoster providing me with a dovecot server (I don't want to do all the admin stuff and backup myself, if possible). I already googled a bit, searched the archives and had a look at dovecot.org but could not find an answer to this question. Since dovecot seems to get a fair amount of funding from finnish companies I thought there should be a good hoster among them. Any hints? Thanks Johannes

[Dovecot] Authentication failure (password mismatch?)

I setup dovecot on my laptop to practice on. I was following some of the information on this page: https://help.ubuntu.com/community/PostfixVirtualMailBoxClamSmtpHowto#Testing Your Setup I created the in this format: user:{plain}pass:1000:1000::/home/user::userdb_mail=maildir:~/Maildir for userdb passwd-file. I used smart for the user and wade for the password (its just for testing) and then attempted to log into the system.

[Dovecot] Dovecot SSL issues
by Spyros Tsiolis 29 Jan '10

29 Jan '10

Hello all, successfully managed to make dovecot work with horde (http://www.horde.org) and another MTA (SMTP/POP3). I have this nagging issue with dovecot though (I suspect - it's dovecot and not the rest of the packages, please read on): There is this special page one goes, that check if everything is ok with all the relevant software running along Horde. It's a php file called "test.php". Now, this file shows almost everything that happens in the box. Here's a transcript of what shows when it comes to dovecot and SSL : --------------------------- * Trying protocol imap/ssl, Port 993: ERROR - The server returned the following error message: SECURITY PROBLEM: insecure server advertised AUTH=PLAINCertificate failure for localhost: self signed certificate: /C=GR/ST=Kerkyra/L=Kerkyra/O=The Company Name/OU=IMAP server/CN=webmail.thecompanyname.gr/emailAddress=postmaster(a)webmail.thecompanyname.gr --------------------------- From what I understand, it doesn't like the certificate. However, I've followed a howto document step-by-step and did what is documented. Does anyone have any pointers on how to make secure imap for dovecot ? E.G. on ThunderBird, the settings are the following : Tools -> Account Settings -> Server Settings : Server Name : (the server or its ip address) Username : (the username) Port : (I've manually entered "993", because by default goes to "143") Security Settings -> Connection Security : SSL/TLS (again manually entered) CHECK_ON : Use secure authentication Now, if I click on "Get Mail" button on top of the TB window, I get a pop-up window with the following message : ------ Server : Location : <Servers' IP Address>:993 Certificate Status : This site attempts to identify itself with invalid information. Wrong Site : Certificate belongs to a different site, which could indicate an identity theft. Unknown Identity : Certificate is not trusted, because it hasn't been verified by a recognized authority. ------ After that, the users accepts the above by pressing ok twice. However, there's a third pop-up window with a message shown below : ------ You cannot log in to <servers' ip address> because you have enabled secure authentication and this serer does not support it. To log in, turn off secure authentication for this account. ------ Any help would be appreciated.. Thank you all for your patience, S. Tsiolis

[Dovecot] mdbox, dsync
by Timo Sirainen 29 Jan '10

29 Jan '10

I finally migrated my mails from mbox format to mdbox format using dsync: 1. Stop dovecot, wait a few seconds for processes to die 2. dsync convert mdbox:~/mdbox 3. Change mail_location to mdbox:~/mdbox 4. Check that no new mails arrived during conversion (alternatively I could have just run dsync again, but I decided not to test my luck) 5. Start dovecot After fixing a pretty bad bug in dsync and a couple of other unrelated bugs, everything seemed to work correctly and transparently. UIDs and everything was preserved as expected. I think I even feel my mail clients being faster than with mbox :) ~% du --exclude=.imap -bsh mail-old-mbox 707M mail-old-mbox ~% du -bsh mdbox/* 27M mdbox/mailboxes 704M mdbox/storage The reason why I'm giving -b is because without it, mdbox was a lot larger than mbox (734 MB vs. 710 MB). I guess this is because zfs internally decided to waste some space for the files. ~/mdbox/storage% ls -lS -rw------- 1 tss tss 13602413 2010-01-29 18:05 m.68 -rw------- 1 tss tss 10487382 2010-01-29 18:06 m.209 -rw------- 1 tss tss 7749964 2010-01-29 18:06 m.270 -rw------- 1 tss tss 7493010 2010-01-29 18:05 m.69 .. -rw------- 1 tss tss 2097246 2010-01-29 18:06 m.175 -rw------- 1 tss tss 2097213 2010-01-29 18:06 m.151 -rw------- 1 tss tss 2097173 2010-01-29 18:06 m.197 -rw------- 1 tss tss 2097163 2010-01-29 18:05 m.89 -rw------- 1 tss tss 1307164 2010-01-29 18:33 m.296 Total of 296 files. The reason why there are a few large files is because their last mail is huge. I guess in future mdbox should try to avoid doing that if it knows the mail's size beforehand. Actually I thought it already tried to do that.. Anyway, let's hope it doesn't now corrupt all my mails.

[Dovecot] dovecot auth feature request
by Frank Cusack 29 Jan '10

29 Jan '10

when i try to run dovecot for SASL support only, with literally just this configuration: protocols = none ssl = no auth default { mechanisms = plain login passdb passwd-file { args = /etc/dovecot/passwd } socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 } } } I get this: Error: ssl_cert_file: Can't use /etc/ssl/certs/dovecot.pem: No such file or directory Since, in this configuration, SSL doesn't have meaning, dovecot shouldn't be looking for any cert file. Easily fixed with "ssl = no" but that shouldn't be required. -frank
