[Dovecot] Howto disable imap listener in dovecot 2.0
by Erik Logtenberg 11 Mar '10

11 Mar '10

Hi, How do I disable the imap listener in dovecot 2.0-beta-3? I only want to enable the imaps listener. In previous dovecot versions I could specify: prototols = imaps But in dovecot 2.0 this is no longer possible (imap and imaps are now both enabled with "protocols = imap"). I already made ssl a requirement with: ssl = required This is in the global section. I commented out the imap listener in master.conf, but "dovecot -a" still shows the config for the imap listener, so I suppose it's default configuration. Can I explicitly tell dovecot to not open an imap listener, but only an imaps listener? Kind regards, Erik.

[Dovecot] Limit login attempts per connection?
by Tony Nelson 10 Mar '10

10 Mar '10

Dovecot allows a large number of login attempts per connection. I'd like to reduce that number to, say, 1, and let my firewall keep the ducks at bay, but I can't find anything in /etc/dovecot.conf or by googling. How do I do it? Do I need to patch the source? dovecot-1.1.10-1.x86_64 on CentOS 5.4 -- ____________________________________________________________________ TonyN.:' <mailto:tonynelson@georgeanelson.com> ' <http://www.georgeanelson.com/>

[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

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

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.....

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?

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. Thanks Foram Goram __________________________________________________________________ Be smarter than spam. See how smart SpamGuard is at giving junk email the boot with the All-new Yahoo! Mail.

I wish you'd have mentioned the Squat plugin earlier Timo. I feel I've made a fool of myself. 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. Anyway, setting up Squat on 1.2.10 sure solved the long search time problem. :) Thanks for the help Timo! -- Stan

[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. The following log entries do not appear on centos 5.4 ------------------ Feb 27 21:17:33 localhost dovecot: pop3-login: Invalid certificate: unable to get certificate CRL: /C=US/ST=New York/L=Astoria/O=SnakeOil Inc./OU=Email Administration/CN=web(a)example.com Feb 27 21:17:33 localhost dovecot: pop3-login: Valid certificate: /C=US/ST=NY/L=TEST/O=Internet Widgits Pty Ltd ------------------- $ dovecot -n # OS: Linux 2.6.9-89.0.20.EL i686 CentOS release 4.8 (Final) ext3 base_dir: /var/run/dovecot/ protocols: pop3 listen: 192.168.0.110 ssl_ca_file: /etc/pki/certs/dovecot/client_ca.crt ssl_cert_file: /etc/pki/certs/vrane.com/pop.crt ssl_key_file: /etc/pki/private/vrane.com/pop.key ssl_parameters_regenerate: 29 ssl_verify_client_cert: yes verbose_ssl: yes login_dir: /var/run/dovecot//login login_executable: /usr/libexec/dovecot/pop3-login mail_location: maildir:/home/vmail/%d/%n mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/pop3 auth default: user: squab debug: yes ssl_require_client_cert: yes ssl_username_from_cert: yes passdb: driver: passwd-file args: /etc/dovecot/shadow/%d userdb: driver: static args: uid=2000 gid=2000 home=/home/vmail/%d/%n socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix

[Dovecot] IMAP Folders Don't Make Sense
by Carlos Williams 27 Feb '10

27 Feb '10

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. When I try and click on the Symantec folder as a sub folder in 'Drafts', I get an error: "The mail server responded:Mailbox doesn't exist: Drafts.Symantec" So why does it show up there and why can't I see it normally with all my other IMAP folders under my Inbox. 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
by Andreas Schulze 25 Feb '10

25 Feb '10

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.

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

Hello, dovecot-1.2.10 dovecot-sieve-0.1.14 dovecot-managesieve-0.11.11 I believe I patched dovecot successfully and compiled the dovecot and dovecot-sieve source tress. patching file README.managesieve patching file dovecot-example.conf patching file src/master/child-process.c patching file src/master/child-process.h patching file src/master/listener.c patching file src/master/login-process.c patching file src/master/mail-process.c patching file src/master/main.c patching file src/master/master-settings-defs.c patching file src/master/master-settings.c patching file src/master/master-settings.h Then I configure dovecot-managesieve and this completes without error. But when I make dovecot-managesieve I get this error: # Making all in managesieve .... main.c:195: error: variable 'managesieve_sieve_env' has initializer but incomplete type # Where should I be looking for a solution?

[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

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)

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.

[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

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
by kjonca＠wp.pl 20 Feb '10

20 Feb '10

Is any posibility to pass parameters/environment variables to deliver with sieve plugin? I have some procmail rules to decide where mail should go, which can't be migrated to sieve (uses external programs). 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
