[Dovecot] Count breaks socket
by Marc Perkel 26 Jan '08

26 Jan '08

If I use the socket option I can't use the count option to create more authentication processes. I get this error. Thanks in advance. dovecot: Jan 25 06:57:04 Error: auth(default): Socket already exists: /var/run/dovecot/auth-client auth default { mechanisms = plain passdb passwd-file { # Master users that can log in as anyone args = /etc/dovecot.masterusers master = yes pass =yes } # Linuxconf passwd-like file with specified location passdb passwd-file { args = /etc/exim/control/vmail/shadow.%d } # Linuxconf passwd-like file with specified location userdb passwd-file { args = /etc/exim/control/vmail/passwd.%d } socket listen { master { path = /var/run/dovecot/auth-master mode = 0666 } client { path = /var/run/dovecot/auth-client mode = 0666 } } # Number of authentication processes to create # count = 10 }

Hi! Using HEAD, and after the 7193:e5af14239137 changeset (Store physical message sizes also to dovecot-uidlist if needed.)

[Dovecot] Capturing credentials for imap sync
by Master Abi 26 Jan '08

26 Jan '08

Hi List All the imap sync apps I could find requires the username /password credentails to be known before a sync occurs. I have Dovecot using ldap acting as a nearline backup mail server to MS Exchange. Every hour imapsync syncs mail between Exchange and Dovecot. This all works fine becuase the users credentials are known, but when new users are added I would like the process to work seemless like this: The user is added to the Active Directory. The mail client is configured with 2 accounts with identical credentials, one of which is connected to Dovecot. When the new client connects to dovecot, the credentials are captured and stored so that imapsync can use it. This If there is another way this can be done with dovecot, could I please be enlighten. I have read the doco on migration but I am not quite migrating but more replicating. Thank you

[Dovecot] symbolic links to root node
by Martin Preen 25 Jan '08

25 Jan '08

Hello, I have a question about the way Dovecot limits file system access. Currently we're using Dovecot 1.0.5 (Solaris 10). In some cases users have a symbolic link like "z: -> /" in their mail directory. As a result there are log entries like Jan 25 13:30:31 imap1 dovecot: [ID 107833 mail.error] IMAP(xyz): stat(/home/xyz/.wine/dosdevices/c:/windows/profiles/xyz/.../z:/proc/28381/root/proc/28381/.../root/proc/28381/Player/#SharedObje Jan 25 13:30:31 imap1 dovecot: [ID 107833 mail.error] IMAP(xyz): x) failed: File name too long We know the reason (the links are create by Wine) but unfortunately we cannot get rid of them. Is there something I can do (these links should be ignored) ? Or is it a bug ? Greetings.

[Dovecot] New server error
by Anne Wilson 25 Jan '08

25 Jan '08

I'm setting up a replacement mail server on a CentOS 5.1 box. The dovecot version is 1.0.rc15. 'dovecot -n' returns # /etc/dovecot.conf login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd I can telnet localhost 143 and log in. I have given kmail the address of the server and an Inbox has been created, but no option to create sub-folders. If I attempt to send a message kmail freezes. Clearly something's wrong. I am using configuration files from the old server, modified only to the new server details. I have alias and transport hashes. What else should I be looking at? Thanks Anne

[Dovecot] dovecot + antispam + sendmail
by Anil 25 Jan '08

25 Jan '08

Whats a good antispam solution? I am using sendmail and dovecot 1.1. I came across dovecot's antispam plugin, but it seems it does not support 1.1 yet. I am also looking for something non-perl based. I am already doing some greylisting with sendmail milter. Any other good suggestions? If not, I guess I might have to downgrade back to 1.0 dovecot. Thanks

[Dovecot] Is there a way to limit multiple POP3 connections?
by patrickm 25 Jan '08

25 Jan '08

Hi all, Please correct me if I'm going about this the wrong way. We currently have a 3 system Mail server set up - two machines are the load balanced frontends running Dovecot and Postfix, and the third machine is our NFS. Over the past 4 months or so, I've tweaked and optimized our mail servers, and we receive roughly 3 million emails a day combined through this setup. Sometimes, the IO Wait is horrible on the load balanced servers - it can get up into the 80-90% range sometimes - it's usually when a lot of email is being passed, or there are a lot of POP3 and IMAP connections. One item which I believe to be hurting I/O performance is the fact I used a RAID 10 setup using SATA II drives on an LSI Logic SATA I controller, in 32 bit mode. Until we rebuild our mail setup (which may be another year down the road), I want to make sure these servers are optimized to the fullest just in case we get heavy I/O usage, it doesn't slow down if at all possible. One thing I noticed is that when issuing a 'ps aux | grep -i pop' or 'ps aux | grep -i imap' I see the same username 2,3,4,5 times, sometimes more. When issuing a 'tail -f /var/log/dovecot.log' I notice that some users log into POP3 every 3 seconds, sometimes sooner. Without upsetting the customer, is there anything I can do on my end to disallow people logging into POP3 multiple times at once? Any tips on this is very much appreciated. Thanks in advance. Patrick

[Dovecot] sieve vacation
by Asbjørn Sannes 25 Jan '08

25 Jan '08

I think sieve vacation is cutting off the last line of the vacation message, is this a known problem? vacation addresses: "john(a)example.com" "not here now" Would return an empty message, changing it to: vacation addresses: "john(a)example.com" "not here now have a nice day" And it would send a message with only "not here now" in it, but not "have a nice day". For the record using: http://dovecot.org/releases/sieve/dovecot-sieve-1.0.2.tar.gz Mvh, Asbjørn Sannes

[Dovecot] Dovecot + MySQL problem
by Timo Neuvonen 25 Jan '08

25 Jan '08

I recently upgraded my Fedora Core 6 (mail)server to Fedora 8. Unfortunately I don't any more have absolutely reliable information available on the Dovecot version that was the last one I had on FC6, but I guess it has been 1.0.3 (I found it from a FC6 repo right now). Currently, Fedora 8 has version 1.0.7 that comes as binary rpm from Fedora repos. So, the problem: I had set up an authentication system using mysql database. It worked fine as long as I were using FC6, but after upgrade Dovecot dies immediatedly after the system startup, writing this to log: Jan 24 16:14:46 test dovecot: Dovecot v1.0.7 starting up Jan 24 16:14:46 test dovecot: auth(default): Unknown database driver 'mysql' Jan 24 16:14:46 test dovecot: Auth process died too early - shutting down My first idea was that Dovecot is compiled without sql support. However: [root@test etc]# dovecot --build-options Build options: ioloop=poll notify=inotify ipv6 openssl SQL drivers: mysql postgresql sqlite Passdb: checkpassword ldap pam passwd passwd-file shadow sql Userdb: checkpassword ldap passwd prefetch passwd-file sql static If I change "mysql" to "pgsql" in the following in the conf file, the error message will change accordingly: # Database driver: mysql, pgsql, sqlite #driver = driver = mysql I also have CentOS 5.1 system with Dovecot 1.0.rc15. I tried the database authentication with similar conf there, it did work. So, is there an essential (intentional) change in sql configuration between 1.0.rc15 (and obviously 1.0.3) to 1.0.7, or should I start finding the problem from incorrectly built binary of 1.0.7? Regards, Timo

[Dovecot] dotlock errors without using dotlock

[Dovecot] Maildir format, "From " in the first line
by Sébastien Munch 24 Jan '08

24 Jan '08

Hello, Using Dovecot's deliver MDA, all mails are stored with the line "From <sender> <date>" appended. When forwarding these mails as attachements, the recipients get the source code. When Postfix delivers emails directly in the Maildirs, this first line is not appended, and there is no problem when forwarding the mails. Why is this line appended by deliver ? Is there a way to remove it ? Or is there something else I can do to avoid this forwarding problem. I'm using Dovecot 1.0.rc15 from Debian Etch.

You could verify that this happens. So I can't really say anything else than that the problem is somewhere outside Dovecot..

[Dovecot] plus-address delivery
by Jon Fullmer 24 Jan '08

24 Jan '08

Forgive me, if this has been previously discussed. I researched as best I could. I couldn't find anyone mentioning it. Please treat me as a newbie. I've recently set up postfix, amavisd-new/SpamAssassin, and dovecot. All three utilize a user database in a MySQL db (on the same host). So far, so good. The problem: I wanted amavisd-new to deliver an e-mail above the "$sa_tag2_level_deflt" to the spam mailbox inside each user account. To accomplish this, I've instituted (best as I can tell) "plus addressing." The idea, if I have this correct, is that if a spam message is being sent to "<user>@<domain>.<tld>", amavisd-new will change the receiving address to "<user>+spam@<domain>.<tld>". The "+spam" will translate to the mailbox named "spam" within the structure of "<user>"'s mailbox. I think the important lines from the amavisd-new config are: @addr_extension_spam_maps = ('spam'); $recipient_delimiter = '+'; Long story short, (too late) the e-mails are being delivered, but to a completely new mailbox called "<user>+spam". For example, when I list the directory "<domain>.<tld>", I now see two mailboxes (as opposed to one): "<user>" and "<user>+spam". Is there something I need to configure within dovecot to have it recognize "plus addressing", or should it do so by default? I'm certain I've just missed something really simple. Any thoughts would be appreciated. Thanks! - Jon

I am having a recurring problem with Dovecot 1.0.8 failing to MIME-decode certain messages. The client is Mulberry 4.0.8. The messages causing the problem seem to be MIME messages with "no parts". I.e. the message has some MIME encoding, but is just included as the message body. The kind of effect I will see is a proliferation of untranslated =xx codes, or in some cases an untranslated base64 block. I.e. I see the raw text from the message body with no MIME decoding at all. When this problem happens, if I close the folder, ditch the .imap directory on the server for this folder, and reopen the folder, the problem has gone away, I can view the message just fine. So, I don't believe it's a client problem. (And Mulberry is probably the most IMAP-knowledgeable client out there ...) Below is my dovecot -n listing. -Thanks, Jim ------------------ # 1.0.8: /usr/local/etc/dovecot.conf base_dir: /var/dovecot/ ssl_disable: yes ssl_cert_file: /etc/ssl/dovecotcert.pem disable_plaintext_auth: no login_dir: /var/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_user: _dovecot mail_location: mbox:~/mail:INBOX=/var/mail/%u mail_full_filesystem_access: yes mbox_write_locks: fcntl imap_client_workarounds: delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep namespace: type: private separator: / inbox: yes namespace: type: private separator: / prefix: mail/ hidden: yes namespace: type: private separator: / prefix: ~/mail/ hidden: yes auth default: passdb: driver: passwd userdb: driver: passwd

[Dovecot] Slow header fetching rate over nfs mailspool.
by Dino Ming 23 Jan '08

23 Jan '08

We are setting up a Dovecot over a pair of NFS which mirrored with DRBD +Heartbeat, under Debian Etch AMD64 with Kernel 2.6.22-5. The problem was slow header downloading rate. We had tried to use postal to inject 500 emails which are under 5KB each, but when ever we start up Mail.app, Thunderbird or even OE6, the header download rate is terrible slow. Its look like a few sec for just 1 header download from the strace of the dovecot process, sometime, it maybe longer and this leading to the MUA hang. We had tried dove 1.0.rc15-2etch3, 1.1beta13... and the following configuration is for 1.1beta13.

[Dovecot] Create IMAP folders on first login?
by Andreas Ntaflos 23 Jan '08

23 Jan '08

Hello list, I am currently playing around with a virtual domain/virtual user setup and thanks to the documentation on both the Dovecot and the Postfix websites things are going swimmingly (apart from an oddity I will post separately about). On trying things out with different newly created virtual users I wondered if it was possible for Dovecot to create certain IMAP folders on the first login of the user? So that folders such "Drafts", "Sent" and "Trash" are created automatically for each new user (upon login). Or is this a job for the mail client, or for the admin who creates the new users? TIA!

[Dovecot] Problem with quota support on debian etch
by Sascha Bendix 22 Jan '08

22 Jan '08

Hi, sorry but I'm new to dovecot and this list and don't know how to proceed with my dovecot installation. I was trying to set up an Mailserver with Postfix, Dovecot and PostgreSQL. Everything was working fine till I wanted to integrate quota support. When I activate it by adding quota to the the imap plugin section (like described in the wiki) I get the following error every time I try to login: Jan 20 19:32:07 kauket dovecot: IMAP(user(a)dmain.de): Unknown quota backend: quota=maildir Jan 20 19:32:07 kauket dovecot: child 11288 (imap) returned error 89 Jan 20 19:32:07 kauket dovecot: imap-login: Login:user=<user(a)domain.de>, method=plain, rip=::ffff:1.2.3.4, lip=::ffff:1.2.3.5, TLS I tried to set quota = maildir:storage=10240 in the plugin section, too and got the same error. I already talked to some dovecot users bot nobody could help me and I hope you can give me an advice what could be the mistake. Here is my Config: # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps listen: [::] ssl_cert_file: /etc/ssl/certs/kauket.maedness.de.crt ssl_key_file: /etc/ssl/certs/kauket.maedness.de.key login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_user: dovecot-auth mail_extra_groups: mail mail_location: maildir:/var/mail/%h mail_plugins: quota imap_quota auth default: user: dovecot passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf # grep -ve '^[ ]*#' -e '^$' dovecot-sql.conf driver = pgsql connect = host=localhost dbname=postfix user=postfix password=password default_pass_scheme = MD5 password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT maildir, 10000 AS uid, 8 AS gid, quota=maildir:storage=' || quota AS quota, maildir AS home FROM mailbox WHERE username = '%u' The system is a debian stable (etch) with package version 1.0.rc15-2etch1 and dovecot --version tells 1.0.rc15. I know the this version of dovecot is a little bit ancient but I hope you can still help me. I even don't know if it's only a bug in the package or if it's a bug in dovecot itself. I thank you for all clues and advices. Sincerly yours, Sascha

[Dovecot] Virtual Users and permission denied on POP3 Authentication - cur directory
by John Dubchak 22 Jan '08

22 Jan '08

Hi, I've been working on configuring a new Postfix+Dovecot+Cyrus-SASL +Postgres server to perform multi-domain virtual hosting with non-unix accounts. I believe I have everything working correctly and have tested both the SASL portion and POP authentication through telnet and all works as expected, with one exception. When I authenticate using POP3: # telnet mail.host 110 Trying 192.168.XXX.XXX... Connected to mail.host. Escape character is '^]'. +OK Dovecot ready. user user1(a)domain1.com +OK pass secret +OK Logged in. -ERR No INBOX for user. And the maillog reports the following: Jan 21 13:42:32 mail.host dovecot: pop3-login: Login: user=<user1>, method=PLAIN, rip=192.168.XXX.XXX, lip=192.168.XXX.XXX Jan 21 13:42:32 mail.host dovecot: POP3(user1): mkdir(/var/spool/ virtual_mailbox/domain1.com/user1/cur) failed: Permission denied Jan 21 13:42:32 mail.host dovecot: POP3(user1): mkdir(/var/spool/ virtual_mailbox/domain1.com/user1/cur) failed: Permission denied Jan 21 13:42:32 mail.host dovecot: POP3(user1): Couldn't open INBOX: Internal error occurred.

The directories have permissions 700. What I believe is happening is that Dovecot is trying to use the uid and gid of user1, who doesn't have a system account, rather than vuser's when writing to the virtual_mailbox folders. I'm not sure how I can configure Dovecot to use the vuser information. Here is my dovecot.conf: ------------------------------------------------------------------------- protocols = imap pop3 listen = [*] disable_plaintext_auth = no syslog_facility = mail mail_location = maildir:/var/spool/virtual_mailbox/%h # Default umask to use for mail files and directories. #umask = 0077 protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster(a)example.com } auth_debug_passwords = yes auth_debug = yes auth_verbose = yes auth default { # SQL database passdb sql { args = /etc/dovecot-sql.conf } userdb sql { args = /etc/dovecot-sql.conf } user = root } ------------------------------------------------------------------------- Any insight will be appreciated, I've been working on this non-stop for several days now and can't seem to figure it out. Thanks, John

[Dovecot] Problem downloading mail with "large" attachment using Thunderbird....
by Bjørn T Johansen 22 Jan '08

22 Jan '08

We have a user that is using Thunderbird on Windows to read mail over IMAP and it works ok, except for downloading mail with "large" attachment.. When opening a mail with a attachment with a size of 14-15MB, TB downloads the attachment seemingly ok, but TB stops when reaching 99%. After TB has stopped, if the user tries to select another mail, TB just hangs and it has to be closed and started again to work again... I have checked the dovecot log, but I can't find anything there... We have also tried to create a log in TB but everything looks ok there also... Is there a known problem with TB and "large" attachment or does anyone know how to fix this, if possible?

[Dovecot] Maildrop script to sieve
by Raphael Bittencourt S. Costa 21 Jan '08

21 Jan '08

Hi, I'm working on a system that have about 350K e-mail users and 100k users that uses maildrop scripts to make filters on their delivery. So, changing scripts by hand can't be a choice. I "googled" so much and I wasn't able to find any script that converts maildrop scripts to sieve. Does anyone knows where can I find it? By the way, does anyone uses dovecot-1.1-beta on a production system with sieve+maildir+lda? Thanks, Raphael Costa

[Dovecot] Exim Dovecot Authentication Problem

Having a hard time figuring out something that is supposed to be easy. Tryiong to configure Dovecot so that it provides authentication to Exim for outgoing smtp. Tried different things and getting authentication socket protocol error dovecot_plain: driver = dovecot public_name = PLAIN server_socket = /var/run/dovecot/auth-client server_set_id = $auth1 auth default { # Space separated list of wanted authentication mechanisms: # plain digest-md5 cram-md5 apop anonymous mechanisms = plain # # Password database is used to verify user's password (and nothing more). # You can have multiple passdbs and userdbs. This is useful if you want to # allow both system users (/etc/passwd) and virtual users to login without # duplicating the system users into virtual database. # # http://wiki.dovecot.org/Authentication # # PAM authentication. Preferred nowadays by most systems. # Note that PAM can only be used to verify if user's password is correct, # so it can't be used as userdb.

[Dovecot] Squirrel Mail (unknown date) in subject and zero size of messages shown
by Niki Spassov 21 Jan '08

21 Jan '08

Hello, I'm having the following problems with a Squirrelmail and Dovecot. with option SERVER SIDE SORTING in Squirrel, only the first page with e-mails is shown in user's inbox, the mails in all the next pages are listed with subject: "(unknown date)" and size 0. The other similar problem, independent from that option (SERVER SIDE SORTING) is: when THREAD VIEW is chosen, we have the same behavior, normal first page and damaged all the others. with option SERVER SIDE SORTING = FASE, and UNTHREADED, everything is OK Has anyone seen this behavior, any help will be greatly appreciated. Thank you in advance :) P.S. Squirrel's version is 1.4.7 and Dovecot is 1.0-stable

Re: [Dovecot] Time just moved backwards error even with ntpd
by Alexander Moisseev 21 Jan '08

21 Jan '08

On some FreeBSD 6.2 systems I was solved this problem just by adding to crontab: @hourly /sbin/sysctl `/sbin/sysctl -e machdep.adjkerntz` >/dev/null 2>&1 For some explanation, see: http://lists.freebsd.org/pipermail/freebsd-hackers/2005-August/013383.html Quote follows: ... It seems that CMOS clock is updated using resettodr(9) function. There seem to be only a few occasions when this function is called: 1. clock_settime(ClOCK_REALTIME) // through kern_time.c:settime() 2. settimeofday() // through kern_time.c:settime() 3. machdep.adjkerntz sysctl is set I believe that ntpd calls *settime-family* functions *only* if time offset is *larger* than *128ms* (or maybe I am thinking about ntpdate), but normally it uses ntp_adjtime() to adjust time keeping. Obviosuly, a system running ntpd with good enough hardware clock and good enough connection to good enough ntp server(s) would use the latter method all of the time after some initial stabilization period. But it seems that time changes are *never propagated to CMOS* in this case, ... Alexander

[Dovecot] Using deliver from Getmail?
by Andreas Ntaflos 21 Jan '08

21 Jan '08

Hello list, a quick question: can I use Dovecot's LDA "deliver" as a destination in Getmail? I.e.: [destination] type = MDA_external path = /usr/local/libexec/dovecot/deliver arguments = ("-d", "username",) Or is deliver not supposed to be called this way? What I'd like to do is use deliver in the same way I would have used procmail ages ago. Getmail retrieves the mail messages, filters them according to the filter sections set up and then puts them in the final destination as noted above. Of course I would like to have deliver honour my .dovecot.sieve sieve script. My first tries have not been very successful, all messages retrieved in this way are put in the top level INBOX, not being sieved. I also got this error message, but I am not sure how it is related: Jan 14 16:08:04 localhost deliver(username): net_connect(/usr/local/var/run/dovecot/auth-master) failed: Permission denied Does my user need any special permissions to use the LDA? TIA! Andreas P.S.: Using Dovecot 1.0.5 with the Sieve plugin. I can post the output of dovecot -n but I don't think it's necessary? -- Andreas "daff" Ntaflos Vienna, Austria GPG Fingerprint: 6234 2E8E 5C81 C6CB E5EC 7E65 397C E2A8 090C A9B4

[Dovecot] v1.1.beta14 released
by Timo Sirainen 20 Jan '08

20 Jan '08

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta14.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta14.tar.gz.sig School has started since beta13 release and I've been a bit busy with it and trying to get my sleeping times fixed (0-2h sleep doesn't seem to be enough). My interest in algorithms has also grown a bit recently. I'm thinking about majoring in CS / algorithmics (as well as biochemistry / possibly bioinformatics). This should only be good for Dovecot's performance in future. :) Pretty much the same things are in TODO for v1.1.rc1 as there were in beta13. But there are quite a lot of other changes: - Added proxy_maybe setting. If the returned IP/port/user points to ourself, log in normally. Otherwise proxy to the IP. - Added quota_exceeded_message setting for quota plugin. Add it to plugin {} for global, or protocol lda {} for deliver-only. - mysql: default_file and default_group settings (by Luca Longinotti) - Timeout handling rewritten using a priority queue (heap). Dovecot should now be able to handle lots of timeouts quite fast. - Using the new timeout changes several places in code have been changed from iterate-through-objects-in-one-timeout to timeout-per-object. This means that there are no longer timeouts triggering every couple of seconds for no reason. dovecot master and dovecot-auth processes haven't been changed yet. - deliver without -d parameter: if $USER and $HOME exists, don't do getpwuid() lookup. - Maildir locking fix - Index file performance fixes - Don't allow RENAME box box/child. It breaks some clients (which do it themselves..) and there's really no reason to allow it. - Quota warnings were broken - Maildir quota didn't use limits from maildirsize if no quota rules were specified I'm also thinking about getting rid of the "time moved backwards" error and change it to a warning. First I'd just need to fix the timeout handling code to handle time jumps and then verify that all timestamp comparisons can handle it correctly. Also besides warning about "time moved backwards" it should warn about "time moved forwards a lot" where "lot" is probably something like a minute. That could cause problems with dotlocks just the same as time moving backwards.

[Dovecot] [Sieve] Sendmail problem
by Roger 20 Jan '08

20 Jan '08

Hi All, it's my first post in this list. I'm running dovecot 1.0.rc15 on my Debian Etch box. It's working very well but I faced a problem with Vacation using Sieve. :-( In fact, after well configuring the system I dont't receive the vacation message, and in the log I found: deliver(my(a)address.test): "2008-01-19 12:05:32 "Info: cmusieve: Using sieve path: /home/path/to/my/homedir/.dovecot.sieve deliver(my(a)address.test): "2008-01-19 12:05:32 "Error: Sendmail process terminated abnormally, exit status 75 deliver(my(a)address.test): "2008-01-19 12:05:32 "Info: sieve runtim error: Vacation: Error sending mail. Any idea about the reason this happen and how to solve? Thank a lot for your help Roger

[Dovecot] Error with 1.1 Beta
by Jeff Grossman 20 Jan '08

20 Jan '08

I am running the latest version of the 1.1 beta and just got the following error: Jan 17 06:20:13 apple dovecot: IMAP(jeff): rename(/home/jeff/Maildir/.Sent Items/dovecot.index.cache.lock, /home/jeff/Maildir/.Sent Items/dovecot.index.cache) failed: No such file or directory Jan 17 06:20:13 apple dovecot: IMAP(jeff): file_dotlock_replace() failed with index cache file /home/jeff/Maildir/.Sent Items/dovecot.index.cache: No such file or directory Is it something I should be concerned about? I had just sent an e-mail about 30 seconds before that one which did not give the error. I will see if I get the error again when I send this one. Jeff

[Dovecot] Master vs Client socket?
by Marc Perkel 20 Jan '08

20 Jan '08

I'm somewhat confused. I need to use a master socket for the dovecot lda but I also need to have a client socket for authenticating through Exim for outgoing smtp. The auth section doesn't allow for two sockets. How do I do this? Thanks in advance.

[Dovecot] Deliver core dump in b13 (hg 20080102)
by mikkel＠euro123.dk 20 Jan '08

20 Jan '08

Hi there I'm redirecting e-mails from mikkel(a)euro123.dk to another account (mikkel2(a)euro123.dk) using sieves "redirect" with sieve 1.1.3. The e-mail is redirected just fine. But deliver still creates a core dump and returns an "e-mail undeliverable" to the sending account (even though delivery is successful). My .dovecot.sieve contains just this: redirect "mikkel2(a)euro123.dk"; keep; As stated before the e-mail is both forwarded and delivered locally just fine. But the sending account receives this error: "<mikkel(a)euro123.dk>: Command died with signal 6: "/opt/freeware/dovecot-20080102/libexec/dovecot/deliver"" Also deliver.log shows some errors (shown below). The nfs_flush_file_handle_cache_dir error makes me wonder - seems like it tries to delete the homedir of the accounts maildir storage. Also it seems to me like a minor error since the delivery functions as it should, apart from the delivery error it returns and the core dump.

[Dovecot] Plans for 1.1beta14 release?
by Adam McDougall 20 Jan '08

20 Jan '08

I've been glancing at the hg changelogs, watching a number of basic fixes going in, including squat and uidlist fixes. Are there any plans for a beta14 release soon to increase exposure to these fixes, or is it in flux too much? My time lately to spend on dovecot has been sparse but I can definitely afford the time right now to roll betas into service because it is convenient. I have some tiny issues to track down that I noticed in the logs but if a new snapshot fixes them already, it saves both of us time.

Does Dovecot support something similar to Exim's ${readsocket} allowing me to custom tailor a query to a unix socket for any type of data? Or does it support authenticating to saslauthd?

[Dovecot] Problem with Quotas
by Ranjith Kumar 20 Jan '08

20 Jan '08

Hi, I am using dovecot 1.0.10 and using passwd-file as userdb. I have enabled quota plugin in /etc/dovecot.conf. Extra fields are added into userdb. user1:X:500:500:User1:/home/user1:/bin/bash:userdb_quota=maildir:storage=1024 Location of the inbox is /var/spool/mail/user1 I dont think this is working. The user already have 5MB in INBOX and if I send a new mail, it is being delivered. Do I need to change any settings? Thanks, Ranjith

20 Jan '08

I wanted to know if more than one INBOX - entry is possible. My situation: Three users with user@domain One Mail-Adress office@domain, where all three users can get the mails. But i dont want to copy the mails from office to the user (like mailinglist), because if one reads a new mail it should be marked as read at all users. Same with answered and deleted. Thanks in advance, Christian

Hi People I have a two question I use dovecot 1.0.10 I have quota maildir 1- I want to use the last version of quota 1.1 in my dovecot , i have to patch then, so which file i have to apply ? http://dovecot.org/patches/1.0/ this one quota-rewrite-1.0.9.diff ??? When i using the original version with out quota new 1.1 , in my mailbox is created a file called maildirsize with the quota , but when a apply the patch the quota this stop work for me. 2- if is posible define a quota per domain? %n(a)domain1.com = 100M %n(a)domain2.com = 0 --- no limit quota or @domain1.com = 100M @domain2.com = 0 --- no limit quota Once again , sorry for my english Thanks

[Dovecot] deliver can't connect to auth server at */usr/local*/var/run/dovecot/auth-master
by Andreas Ntaflos 20 Jan '08

20 Jan '08

Hello list, while fiddling around with the configuration so Dovecot's LDA "deliver" can be used by multiple users by means of Getmail (you can read about that in [1]) I always end up running into the error message posted in the subject line: Jan 15 00:00:02 HOSTNAME deliver(USERID): Can't connect to auth server at /usr/local/var/run/dovecot/auth-master: Permission denied Notice how it says "/usr/local/var/run/dovecot"! How and why does dovecot ^^^^^^^^^^ think that anything of any importance can be found under /usr/local/var/... ? Please see dovecot -n at the end of this message, but as far as I can tell I never ever specified that the /var directory (configure --localstatedir) should end up under the prefix /usr/local. Now I am quite sure that my configuration for auth-master is not yet quite correct but I can't go any further without asking what this error message could mean and how to resolve the problem. Anybody have any ideas? I am currently running 1.0.10 (previously, until this afternoon 1.0.5, same problem) with the latest MANAGESIEVE patch (v9) applied and the dovecot-sieve plugin. TIA for any hints! I am at a loss here.

[Dovecot] Imap - Loging
by Andre Hübner 20 Jan '08

20 Jan '08

Hello List, i'm looking for a way to increase log-level for imap-processes. Pop3 Server writes all necessary infos about mails-transfered/deleted etc. Imap-Log writes just times and ip's of Userlogins. Is there a way to increase the imap-output? The Conf-Parameters i found did not really fit my requirements. Best result would be a collected log of transfering/deleting mails for one imap-session. Ist there a way to achieve this? Thank you Andre

[Dovecot] quota_wrning not working for me (quota_rewrite patch for dovecot 1.0.8)
by Juan C. Blanco 20 Jan '08

20 Jan '08

Hello, We are using dovecot 1.0.8 with LDAP authentication and extra variebles (like quota limit) storage. Since some of our users are asking for warning of quota use I have been playing around with the quota rewrite patch for dovecot 1.0.8 and found that it does not work for us as it is now. I've applied the patch recompiled dovecot reconfigured using the new "quota_warning" options for a test user with a 10MB quota and warning limits in the 45 and 50 percent. The script for the warnings was never executed and then I've done some debugging with the code and found two different problems (well, at least I think that there are two problems but I may be wrong) The first problem is with the parsing of percentage limits in the quota_warning options. The function "quota_rule_parse_percentage" was using the same value for the variables "percentage" and "*limit" and then the calculated value is not a percentage of the default quota rule limit but of the percentage itself (i.e. using a 80% limit returns a value of 64 for the internal saved limit, instead of 80% of the default rule value). In my sample a 50% limit returned a value of 25 bytes for the limit instead of 5,120. The other problem is when checking the limits to execute the scripts, the "quota_warnings_execute" function is checking if the warning limit is reached with this comparison: if ((bytes_current < warnings[i].bytes_limit && bytes_current + ctx->bytes_used >= warnings[i].bytes_limit) || ... My debug have reported that at the point of the execution of this function the "bytes_current" variable already includes the size of the current transaction (at least it was in all my tests) and then the first part of the comparison (that we are under the limit prior to this transaction)is false. I've changed this to: if ((bytes_current - ctx->bytes_used < warnings[i].bytes_limit && bytes_current >= warnings[i].bytes_limit) || ... I've included the modified patch in this messag but since this is my first contact with dovecot code I'm not sure enough if the problems was with the code or if it was my fault. There is someone using the quota-rewrite patch and can confirm if it was working fine?. Can the author of the original patch take a look at it and confirm if I'm wrong or my changes are valid I don't have a Dovecot 1.1 working here and can not verify if the problems occurs also with this vesion, however the code seems the same after a quick look at it and I think that may be usefull to recheck the code prior to the RC stage.

[Dovecot] file system permissions
by Anil 20 Jan '08

20 Jan '08

I am using Maildir and virtual domains. I have the following definitions in the dovecot.conf: mail_uid = 10000 mail_gid = 10000 mail_location = maildir:/var/mail/apps/%d/%n/Maildir ... Userdb database is LDAP based. Some users in LDAP might have a uid/gid defined. If thats the case, I want dovecot to use those uid/gid. If the user in LDAP does not have a uid/gid attribute, it'll fall back to using mail_uid/mail_gid as defined above. (atleast thats what I am hoping to do...) I set the permissions of /var/mail/apps, /var/mail/apps/%d directories 1777. I also see the following error message when a message is received to one of the users: Jan 13 18:33:33 vds5 deliver(admin(a)domain.com): [ID 702911 mail.error] stat(/var/mail/apps/domain.com/admin/Maildir/tmp) failed: Permission denied The permissions of this tmp directory are: drwx------ 2 vmail vmail 2 Jan 13 18:31 tmp Why is deliver having problems writing to that? At this point, what uid is deliver running as? Thanks!

[Dovecot] maildirsize quota does not referred after migration from courier
by Tim Chen 20 Jan '08

20 Jan '08

Dear All, We would like to migrate our existing courier to dovecot. After reading document on website and doing some tests, here are some issues we met. 1. According the the wiki, it seems to imply that once migrating from courier to dovecot, pop3 users may "lost/forget" their download "index/ history" which cause them to download again old mails that are kept on server side. If this is true, it would seriously annoy our users since they always keep old mails on server so that they can access them through webmail interface. Is there anyway to avoid this kind of situation? 2. Currently, we use only /etc/passwd to store our user information. Postfix is our MTA and maildrop is MDA. Quota settings were wriiten in the maildirsize file reside under Maildir directory at everyone's home. The command we use to set user quota: /usr/local/bin/maildirmake -q 315000000S Maildir After installing a test environment using dovecot v1.1.beta13, we found that it does not read the quota settings from the maildirsize file, instead, it only rely on the system wide settings. This could be a problem since we have different quota settings for different groups of users. Is this a bug of v1.1? Or should I use v1.0 instead? Will v1.1 fix this bug in the future? Best regards, Tim Chen

That's why I suggested to use ntpdate to force the correct time to be set before ntpd even starts and the ntp init script returns. Admittedly, this won't work if you have no network connectivity during boot up, but if you have, this paticular problem is most likely solved. ntpdate optionally can be given a timeout value and indicates success or failure via its return code so that a calling script might initiate appropriate measures.

[Dovecot] Time just moved backwards error even with ntpd

Scenario: server PC abruptly switched off due to power cable problems (an UPS cannot solve this issue), so during shutdown Linux was not able to resinchronize the system clock. After a few hours the server come back on, Linux booted and the services (ntpd, dovecot and many others) started But the system clock was 45 minutes ahead, so: Jan 19 11:13:39 gw ntpd[2112]: synchronized to LOCAL(0), stratum 10 Jan 19 11:13:39 gw ntpd[2112]: kernel time sync disabled 0041 Jan 19 11:14:43 gw ntpd[2112]: synchronized to 62.48.35.100, stratum 2 Jan 19 10:31:55 gw ntpd[2112]: time reset -3600.221385 s Jan 19 10:31:55 gw ntpd[2112]: kernel time sync enabled 0001 Jan 19 10:31:55 gw dovecot: Time just moved backwards by 3600 seconds.

[Dovecot] Public mailboxes
by libero1 19 Jan '08

19 Jan '08

Ciao everbody, I have a simple question for who has a few experience with dovecot. I want to share a mailbox with some users, I configure dovecot and now in my thinderbird I can see the public namespace. The problem is that I cann't see the "inbox" of the mailbox, in other words when a mail arrive in this mailbox I can not see it, but only what is in other folders. Why? Is it normal? What can I do to let my users to see new messages? Thanks for you help. Bye

Hi FETCHing a largish (~30K) zlib compressed maildir message causes an assertion failure on an attempt to grow the stream buffer to smaller than its current size. I believe the attached patch fixes this.

[Dovecot] Out of the box: Thank you!
by Patrick Ben Koetter 17 Jan '08

17 Jan '08

I've just enabled IMAP quota support on a LDAP userbase in about an hour. In this hour I read the Dovecot documentation on quota support, extended the customers LDAP schema, added a "mailQuota"-attribute and a value to all users, enabled the plugin in dovecot.conf, added the attribute query in dovecot-ldap.conf, reloaded the system and tested the functionality and ... everything worked out of the box. Thank you Timo! p@rick -- state of mind Agentur für Kommunikation, Design und Softwareentwicklung Patrick Koetter Tel: 089 45227227 Echinger Strasse 3 Fax: 089 45227226 85386 Eching Web: http://www.state-of-mind.de Amtsgericht München Partnerschaftsregister PR 563

[Dovecot] Need help to install dovecot on solaris 10 with openldap libs
by Dovecot Jami 17 Jan '08

17 Jan '08

Hi, I install dovecot with ldap support at Solaris 10 (x86). I know that solaris LDAP is broken and so I install openldap. OpenLDAP shared libraries are at /usr/local/lib and /usr/local/include. While installing dovecot, I did the followings: I execute this before run "./configure --with-ldap" LDFLAGS="-L/usr/local/BerkeleyDB.4.2/lib -R/usr/local/BerkeleyDB.4.2/lib -L/usr/local/lib -R/usr/local/lib" but dovecot is using the Solaris default LDAP lib files. I also run LDFLAGS="-R/usr/local/lib" and LDFLAGS="-L/usr/local/BerkeleyDB.4.2/lib -L/usr/local/lib /usr/local/lib/libldap-2.3.so.0 " But dovecot is still using solaris ldap libs. ldd /usr/local/libexec/dovecot/dovecot-auth libcrypt_i.so.1 => /usr/lib/libcrypt_i.so.1 libpam.so.1 => /lib/libpam.so.1 libldap.so.5 => /usr/lib/libldap.so.5 libsocket.so.1 => /lib/libsocket.so.1 libnsl.so.1 => /lib/libnsl.so.1 librt.so.1 => /lib/librt.so.1 libsendfile.so.1 => /lib/libsendfile.so.1 libc.so.1 => /lib/libc.so.1 libgen.so.1 => /lib/libgen.so.1 libcmd.so.1 => /lib/libcmd.so.1 libsasl.so.1 => /usr/lib/libsasl.so.1 libmd5.so.1 => /lib/libmd5.so.1 libnspr4.so => /usr/lib/mps/libnspr4.so libplc4.so => /usr/lib/mps/libplc4.so libnss3.so => /usr/lib/mps/libnss3.so libssl3.so => /usr/lib/mps/libssl3.so libmp.so.2 => /lib/libmp.so.2 libscf.so.1 => /lib/libscf.so.1 libaio.so.1 => /lib/libaio.so.1 libpthread.so.1 => /lib/libpthread.so.1 libthread.so.1 => /lib/libthread.so.1 libdl.so.1 => /lib/libdl.so.1 libsoftokn3.so => /usr/lib/mps/libsoftokn3.so libplds4.so => /usr/lib/mps/libplds4.so libdoor.so.1 => /lib/libdoor.so.1 libuutil.so.1 => /lib/libuutil.so.1 libbsm.so.1 => /lib/libbsm.so.1 libsecdb.so.1 => /lib/libsecdb.so.1 libtsol.so.2 => /lib/libtsol.so.2 libm.so.2 => /lib/libm.so.2 Please help me to solve this problem.

[Dovecot] convert plugin fails - drops root privileges then tries to create file in /
by Mikel Ward 17 Jan '08

17 Jan '08

Hi I just tried to run the convert plugin as described at http://wiki.dovecot.org/Plugins/Convert (except with mail_location = maildir:~/Mail) It fails with an error message: Eopen(/.temp.falcon.endbracket.net.18618.8d5e0a038da6cf06) failed: Permission denied Error: imap dump-capability process returned 89 It looks like Dovecot execs /usr/libexec/dovecot/imap, which drops root privileges (probably via get_imap_capability), then loads /usr/lib/dovecot/imap/lib01_convert_plugin.so, which tries to create a file in the root directory, which it obviously won't have write privileges on. I'm running dovecot-1.0-1.2.rc15.el5 on CentOS 5. If I change the paths from ~ to /home/%u, I get this error message: Emkdir_parents(/home/dump-capability/mail) failed: Permission denied

[Dovecot] Postfix & Dovecot LDA
by tomzu＠buu.lv 17 Jan '08

17 Jan '08

Hi, I was using Dovecot (POP3,IMAP+quotas) with postfix quota "addon". But the postfix's quotas were reported differently and the quota file gets messed up all the time. So now I have also Dovecot's LDA, and everything works like charm... but... Now postfix can pass only one mail at a time to LDA. And that slows down delivery. Postfix master file: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} Is there a way to pass more than one mail at a time?

[Dovecot] Deliver, sendmail, virtual users, and catch-all addresses
by Eric Loyd 17 Jan '08

17 Jan '08

I have spent a long time looking into this and can't find the answer I'm looking for, so I'm asking here. I'm cutting the example down to just the bare minimums. This is NOT my actual configuration, but is sufficient for asking this question: How can I use dovecot's deliver LDA to deliver to virtual users, but then have unknown virtual users fall back to catch-all addresses defined by sendmail? Background: * sendmail is the MTA. I do not wish to change this. * procmail is the default MDA. * deliver is set up per the dovecot documentation as another MDA. * mailertable is configured to send mydomain.com to dovecot:dovecot * SQL backend for user/passwords I have it working the way I want with the exception of catch-alls. I thought that it might work by adding @mydomain.com to virtusertable, but sendmail sees the "user not found" return from deliver as the MDA and bounces the mail to postmaster. So what I'm trying to accomplish is this: Mail from user(a)external.com to me(a)mydomain.com Deliver to me Mail from user(a)external.com to sales(a)mydomain.com (virtual) Deliver via deliver to sales(a)mydomain.com Mail from user(a)external.com to foobar(a)mydomain.com (invalid) Deliver to catchall - spam(a)otherdomain.com Can someone point me in the right direction. RTFM is fine if you'll tell me what FM to R, because I've run out of ideas... Thanks! -- Eric Loyd

[Dovecot] Regarding the UIDLIST
by Kjartan Andreassen 17 Jan '08

17 Jan '08

Hi, I wonder if the UID's in the UIDLIST will ever change for a given email? Eg with courier it is recreated sometimes, but can i 100% rely on that the UIDs will never change? Or is there anything else i can rely on that will never change? The reason I'm asking is that i want to link certain tasks etc etc to an email, and the only way to get a unique link is that if the uidlist or something else unique never changes. Thank you. -- Kjartan

[Dovecot] old master.pid prevents dovecot startup
by Michael 16 Jan '08

16 Jan '08

Summary ======= After an unclean shutdown the file /var/run/dovecot/master.pid remained behind. This prevented dovecot from starting, and gave a misleading error message. To be more resilient and fault-tolerant, I recommend that dovecot also check the validity of the PID in /var/run/dovecot/master.pid in order to determine whether or not another dovecot process is running. Detail ====== In testing out my automatic UPS shutdown I inadvertently shut down my system uncleanly ... oops! As the system rebooted, I saw that dovecot did not start properly, with an error message: Fatal: Invalid configuration in /etc/dovecot.conf After the system came up, I tried to start dovecot manually. Turns out that there was an invalid PID in /var/run/dovecot/master.pid ----- [root@mykiss5 mth]# service dovecot start Starting Dovecot Imap: Error: Dovecot is already running with PID 1965 (read from /var/run/dovecot/master.pid) Fatal: Invalid configuration in /etc/dovecot.conf [FAILED] [root@mykiss5 mth]# ps 1965 PID TTY STAT TIME COMMAND [root@mykiss5 mth]# rm /var/run/dovecot/master.pid rm: remove regular file `/var/run/dovecot/master.pid'? y [root@mykiss5 mth]# service dovecot start Starting Dovecot Imap: [ OK ] [root@mykiss5 mth]# service dovecot stop Stopping Dovecot Imap: [ OK ] [root@mykiss5 mth]# service dovecot start Starting Dovecot Imap: [ OK ] [root@mykiss5 mth]# dovecot --version 1.0.7 [root@mykiss5 mth]# ----- This leads me to believe that dovecot is only checking for the existance of /var/run/dovecot/master.pid. It seems to me that it would be more fault-tolerant if it also checked the validity of the PID that is in /var/run/dovecot/master.pid. Michael

[Dovecot] Maildir handling
by Sascha Holzleiter 14 Jan '08

14 Jan '08

Hi, we just setup a new mailserver for our company with some sieve filtering in place. Everything works as expected but there is one flaw. We setup the per user sieve filters in files within the users mailbox maildir as follows: lrwxrwxrwx 1 mail mail 21 Jan 13 17:20 .dovecot.sieve -> sieve/phpscript.sieve This link is actually picked up by dovecot and being announced as an IMAP folder which gives an error in certain MUAs as they try to access it. Is there a way to let dovecot check if the link is really a maildir, so lets say a directory with a maildirfolder file within it? Or just to hide this link from dovecot so its not advertised as an IMAP folder? Greetings, Sascha

[Dovecot] Unexplained MDA bounce backs

I have recently noticed that some of our internal mailer scripts are causing Dovecot-LDA to generate Mailer Delivery Subsystem messages. The following Dovecot-LDA message is generated: ---- Message body ---- Your message was automatically rejected by Dovecot Mail Delivery Agent. The following reason was given: Unknown error ---- Message body ---- ---- Message header ---- Return-Path: <MAILER-DAEMON> Delivered-To: bounces@xxxxx Received: by mymachine.xxxxx (Postfix, from userid 5000) id 5772568300; Mon, 14 Jan 2008 18:00:56 +1100 (EST) Message-ID: <dovecot-1200294055-774265-0@mymachine> Date: Mon, 14 Jan 2008 18:00:55 +1100 From: Mail Delivery Subsystem <noreply@xxxxx> To: <bounces@xxxxx> MIME-Version: 1.0 Content-Type: multipart/report; report-type=disposition-notification; boundary="21506/mailfilter02" Subject: Automatically rejected mail Auto-Submitted: auto-replied (rejected) Precedence: bulk ---- Message header ---- Initially I thought these were being caused by Delivery-Receipt requests, however have since tested this and is not the case. I have tried to snoop through the logs (unfortunately on a very busy mail hub) using the Message-ID, however this doesn't seem to lead me back to the original message - only the MDA notification. I can only ascertain that its isolated to our scripts, as the bounces@ address is specifically used by them. Any ideas what would cause/trigger the "Unknown error" automatic rejects ? System config is -Postfix 2.3.4 with MySQL backend -Dovecot 1.0.rc26 with MySQL backend, using only deliver. All mail deliveries are otherwise fine.

[Dovecot] Imap proxy with tls?
by Someone Something 14 Jan '08

14 Jan '08

Hello all, I have a server with dovecot installed with imap and tls working (call that the remote server). Now I want to have a few computers at the same place to access the same account on the remote server. I have another server (call this the local server) at the local site to do this with but am not sure how to do it. The proxy setup http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy looks about right but that does not seem to support tls? I need tls going from the local server to the remote server. I want all emails on the remote server to be the same as on the local server. This way all clients at the local site have very fast access to email and can still get to the email when not at the local site. Any suggestions? Thanks

[Dovecot] Custom 'quota exceeded' message + Sieve script from database
by Przemyslaw Wegrzyn 13 Jan '08

13 Jan '08

Hi! I'm quite new to Dovecot. helping my friend to migrate from Courier-IMAP to something more efficient, we are evaluating Dovecot at the moment. I had to prepare 2 small patches for Dovecot to suit our needs, and I've decided to post it here. I'm not fully familiar with Dovecot architecture yet, I'd appreciate if someone could look if these changes make sense (i.e. doesn't break anything). And of course, maybe someone is interested as well. 1. Customized "quota exceeded" message. http://czajnick.sitenet.pl/dovecot/dovecot_1.0.9_quota_exceeded_message.diff - quick hack to let me define custom message instead of typical "Quota exceeded", simply by using plugins { quota_exceeded_message = ... }. Browsing this mailing list I've seen some posts about such feature being implemented in Dovecot. Is it done in a similar way? Which stable version is the first to include this functionality? 2. Sieve filter modification http://czajnick.sitenet.pl/dovecot/dovecot_sieve_1.0.2_envscript_patch.diff In our systems we currently use a modified maildrop MDA that picks the filter script from the database instead of the file. This has proven useful - end-user's administration panel doesn't need any special permissions (or networking capabilities), as it doesn't need to access the filesystem - it is reduced to a plain database web-app. The patch above makes the delivery agent check for the sieve script present in SIEVE_SCRIPT environment variable. If this is the case, env var content is used instead of the script stored in a usual file pointed to by SIEVE variable. This makes it trivial to pass the script from the database using base dovecot functionality. A minor drawback of such solution is that the script is re-compiled on each delivery, but I don't think it takes much time to compile a few lines of a script using (f)lex/bison-or-yacc parser. Yes, I've noticed the sieve-manage patch, but I don't want the complexity of managing sieve script over the socket connection (if my understanding of the script is wrong, please correct me). BR, Przemyslaw

[Dovecot] do not lose mail when dovecot is dead
by Daniel 13 Jan '08

13 Jan '08

Hi! Recently I've experienced problems with dovecot. Dovecot died silently, what means is that there are no core files, nor any indication in the log files, just the "kevent(): Invalid argument" messages. Dovecot just died, so deliver could not connect to the auth-master socket, which means that messages couldn't been delivered. The problem is that postfix thought that the delivery was successful, and didn't place the message to delay, but deliver(LDA) couldn't deliver the message, so it got lost. An example: postfix/pickup[29619]: 8A1C6F261: uid=1001 from=<id> postfix/cleanup[19148]: 8A1C6F261: message-id=<20080107192402.8A1C6F261(a)domain.hu> postfix/qmgr[29441]: 8A1C6F261: from=<id(a)domain.hu>, size=585, nrcpt=1 (queue active) deliver(leva): Loading modules from directory: /usr/local/lib/dovecot/lda deliver(leva): Module loaded: /usr/local/lib/dovecot/lda/lib10_quota_plugin.so deliver(leva): Module loaded: /usr/local/lib/dovecot/lda/lib90_cmusieve_plugin.so deliver(leva): Can't connect to auth server at /var/run/dovecot/auth-master: Connection refused postfix/pipe[8582]: 8A1C6F261: to=<leva(a)domain.hu>, orig_to=<id>, relay=dovecot-lda, delay=1.7, delays=1.1/0/0/0 .68, dsn=2.0.0, status=sent (delivered via dovecot-lda service) postfix/qmgr[29441]: 8A1C6F261: removed See? Postfix removed it from the queue, so basically all bets are off, and everything depends on deliver, but it just dropped the message. Is there anything that can be done regarding this issue? Thanks!

[Dovecot] randomly disconnected with imap, and latest hg
by Daniel 12 Jan '08

12 Jan '08

Hi! I'm using latest hg from the 1.1 branch, and noticed that since yesterday's updates, dovecot randomly disconnects clients when using imap, with these message in the log: "Disconnected for inactivity in reading our output bytes=153/41319" This happens randomly. Eg. I'm fetching messages, and suddenly, dovecot disconnects. Or my MUA just sits there, and then again, dovecot disconnects me with this message. I didn't even do anything with the client, so I can't think of anything which could've been read. What could be the problem? Daniel

[Dovecot] Please help me resolve why mail isn't being delivered to virtual users
by Andrew Falanga 12 Jan '08

12 Jan '08

Hi, I have to admit that I'm not quite sure why no one has responded to me about this one. If I'm not providing enough information or incorrect information please tell me. It's quite important that this e-mail system be working. I do not quite understand what it is that I'm missing now. I have the need to setup and configure various users as virtual users. To this end, I've configured them so that their home directories are "/virtusers/<userid>" and their INBOXes are "/var/mail/<userid>." I have created a system user ID called "vmail" which is referenced in my PostgreSQL database for UID/GID stuff. All virtual user home directories and INBOXes are made owner "vmail" and group is "users." Originally, I had my sendmail "/etc/mail/aliases" file setup to "map" all mail sent to these virtual users to the system user "vmail." However, none of the virtual users were getting any mail and vmail was just getting swamped. After doing more digging, I found that I just didn't understand the home directories and INBOX, mbox and such. That's what drove me to configuring what's in there now. Now, following directions on this WIKI page: http://wiki.dovecot.org/LDA/Sendmail?highlight=%28deliver%29 I'm still unable to get the e-mail working for them. Continually, sendmail bails with errors saying it, "Can't create output." Because I am using *.mc files, I made a new *.m4 file as directed in /usr/share/sendmail/cf/mailer. Dovecot does allow the virtual users to login. In fact, when I did, the first time, there appears a "mail" directory in their home directories after login. This would indicate to me that the login was successful. Further, I cut/pasted a message sent to one of the virtual users from the vmail INBOX (/var/mail/vmail) into the virtual user's INBOX (/var/mail/jdunkin). Then, logged in as this virtual user and ACTUALLY got the mail. I know this stuff works. What must be done to make sendmail do its thing for deliver? What is necessary to fix this situation? Andy

[Dovecot] Dovecot-imap, tls, gnus
by Richard G Riley 11 Jan '08

11 Jan '08

I have a connection to my dovecot server from gnus: ,---- | (add-to-list 'gnus-secondary-select-methods | '(nnimap "hermes" | (nnimap-stream starttls) | (nnimap-address "hermes") | (nnimap-authinfo-file "~/.authinfo"))) `---- If I enter a group and read my mail then wander off and come back after a few minutes I can not navigate out of the group because my nnimap session has ended. What config parameter do I need to change in Dovecot to keep it open for the life of the client? (I am assuming its a dovecot issue here since it didn't happen with courier-imap).

[Dovecot] Automatically subscribe to folder?
by Christian Flothmann 11 Jan '08

11 Jan '08

Hello everybody, i am filtering e-mails using the cmusieve-plugin. A global script filters all mails tagged by SpamAssasin and moves them into the folder Spam: if header :is "X-Spam-Flag" "YES" { fileinto "Spam"; } My problem is that users who did not had a folder Spam until the first time of filtering a spam mail are not automatically subscribed to this new created folder. They have to do this step manually in their mail client. Is it possible to automate this script and subscribe the account to this folder when it is created by the sieve script? Regards, Christian

[Dovecot] Test Environment Question
by Stewart Dean 11 Jan '08

11 Jan '08

I have my master IMAP server running DC V1.0.10. The homedir and INBOXdir are physically resident there and NFS exported (no caching) to 3 other machines. I have installed V1.1beta13 on one of them (which thus accesses the homedir/INBOXdir remotely) and plan to have a limited community test-drive it there. Are there any hazards or drawbacks in doing this? While the homedirs and INBOXdirs are thus shared, I have it so that each machine has its own local index directory and /var/run dir. Comments or dire warnings?

[Dovecot] virtual domains/users and LDAP
by Anil 11 Jan '08

11 Jan '08

I have two suffixes in LDAP with users, e.g. ou=People, o=example.com ou=People, o=somethingelse.com I have the following two users: dn: uid=test1, ou=People, o=example.com uid: test1 mail: test(a)gmail.com dn: uid=test2, ou=People, o=somethingelse.com mail: test(a)yahoo.com uid: test2 The users login to IMAP as: test1(a)examle.com and test2(a)somethingelse.com. Here's an (excerpt) of the dovecot.conf file I am using: auth_bind = yes base = ou=People,o=%d scope = onelevel pass_attrs = mail=user pass_filter = (uid=%n) userdb static { args = uid=vmail gid=vmail home=/var/mail/apps/%d/%n } The problem I am seeing when the user logs in, the home dir is getting created incorrectly: Jan 3 14:08:12 vds5 dovecot: [ID 107833 mail.info] imap-login: Login: user=<test(a)gmail.com>, method=PLAIN, rip=, lip= Jan 3 14:08:12 vds5 dovecot: [ID 107833 mail.info] IMAP(test(a)gmail.com): Effective uid=500, gid=500, home=/var/mail/apps/gmail.com/test Jan 3 14:08:12 vds5 dovecot: [ID 107833 mail.info] IMAP(test(a)gmail.com): maildir: data=/var/mail/apps/gmail.com/test/Maildir ... I was expecting it to create the home dir under: /var/mail/apps/example.com/test1, since that is what they are logging in with. Any ideas? I am actually surprised that it even let me login with this configuration, something looks odd in this setup. :) Thanks, Anil

[Dovecot] Problems with AUTH=PLAIN in pop3
by Maykel Moya 11 Jan '08

I'm using Dovecot (1.0.10) locally to test SugarCRM. When I tried to set up a mail account in Sugar, it complains with -- SECURITY PROBLEM: insecure server advertised AUTH=PLAIN Please check your settings and try again. -- don't know if that behaviour is a bug or a feature of php-imap. The case is that I'm unable to set up the mail account in Sugar. Timo answered to me on IRC about Dovecot assuming that a connection from the same ip is considered secured. I'd rebuild Dovecot with the following patch: --- dovecot-1.0.10/src/pop3-login/client.c.orig 2008-01-05 00:44:14.000000000 -0500 +++ dovecot-1.0.10/src/pop3-login/client.c 2008-01-05 00:44:30.000000000 -0500 @@ -331,7 +331,7 @@ client->created = ioloop_time; client->refcount = 1; client->common.tls = ssl; - client->common.secured = ssl || net_ip_compare(ip, local_ip); + client->common.secured = ssl; client->common.local_ip = *local_ip; client->common.ip = *ip; --- but still not able to make it not accept AUTH PLAIN authentication from the same ip. I'm missing something? On the other hand, if I set disable_plaintext_auth to yes I cannot use the classic USER/PASS pop3 verbs. I'm not sure what the POP3 related RFCs mandates with respect to this.

[Dovecot] Switch from courier to dovecot
by Richard G Riley 10 Jan '08

10 Jan '08

I have an courier IMAP server running. To get sib dirs working I had to rename them all to begin with a period ".". e.g Maildir Maildir/{cur,new,tmp} Maildir/.account1/{cur,new,tmp} Maildir/.account2/{cur,new,tmp} Maildir/.account3/{cur,new,tmp} etc If I uninstall Courier and install dovecot, will these "period" dirs be seen by default? I am fairly new to this and sometimes it seems that Maildir format requirements vary a lot depending on client or server. Thank you for your help.

[Dovecot] Dovecot indexing questions
by Asheesh Laroia 10 Jan '08

10 Jan '08

I was playing with Dovecot 1.1 full text indexing through Squat in late October, which was working pretty well. I wanted to ask about this behavior I had: When an email arrives in INBOX using procmail (which delivers to my Maildirs), and I see it in Dovecot, when I next do a search (IMAP SEARCH TEXT) of that folder, the search takes a long time. Successive searches are lickety-split. My question is: Can there be an option to "index greedily"? As soon as Dovecot sees the message, I'd like it to update the Squat index. That way, searches are always fast. I guess this implies a small performance hit - namely, that my IMAP server spends CPU and disk time indexing every message at the first time it is seen rather than being able to do batch indexing each time SEARCH TEXT is issued. But when I think about that, that sounds like the server can waste its time so I don't waste mine - which is exactly why I like these computing machines! (That, and because I can waste my time programming them.) -- Asheesh. -- Use extra care when cleaning on stairs.

[Dovecot] Logging to stderr
by Abhijit Hoskeri 10 Jan '08

10 Jan '08

Hi, I am having a bit of a problem with logging to stderr. I am trying to run dovecot as sort of "inetd" install using daemontools. I have daemontools 'services' named dovecot-pop3, dovecot-imap, etc. The service command line looks like tcpsvd -c20 -v -l 0 0 110 /usr/lib/dovecot/pop3-login [--ssl] In dovecot/dovecot.conf, the log_path is set to /dev/stderr. What seems to be happening is that all the log lines (regardless of service) go to the log file of which ever service was first used. Exactly how are these logs written? Is it possible to (easily) make the login process write to its own stderr? Thanks, -Abhijit

[Dovecot] Sendmail, procmail, dovecot and quota
by papi mac 10 Jan '08

10 Jan '08

I have Fedora 7 from a standard installation running sendmail, procmail and dovecot 1.0 installed on a single partition. I now need to set up mail quotas for most of the users but not all. Just protecting /var/spool/mail/$LOGNAME is probably good enough for me. Since I just want mail quotas and the installation is on just 1 partition I don't have an easy way to use file system quotas. By reading through the dovecot documentation and list archives I have the feeling that this is possible with the versions and setup I have. I would probably need a main line like this (apart from other lines) per user mailbox that needs to be managed: dirsize:/var/spool/mail/joe-user:storage 10240 to give joe-user a 10 mb limit. Since this server is in production I don't have the luxury of experimenting (extensively) on it. I have a question though that I have not been able to answer yet. If the flow of mail goes from sendmail to procmail to the mailbox, how is it possible for dovecot to implement quotas on the inbox? Or would dovecot write something there that procmail has to honor? Is dovecot the way to do this? Am I misunderstanding what "quotas" mean in dovecot? Thanks for any clues. --------------------------------- Looking for last minute shopping deals?

[Dovecot] Dovecot auth GSSAPI

Hi, I have Heimdal Kerberos with authentication in my Samba PDC, Postfix and OpenLDAP, it is perfect. But, I have problem with authentication GSSAPI of Dovecot.

Hi, I'm currently using Dovecot version 1.0 and I want to update it to the latest version. I know from version .99 to version 1.0 I had to change a few things on the dovecot config. When compiling the latest stable version should I just be able to use the same config I'm using for version 1.0 without making any changes ? Thank you Paul

[Dovecot] Dovecot too many open files???
by Tim Tyler 08 Jan '08

Dovecot experts, We just recently deployed Dovecot 1.0.rc15 on a Redhat 5 system. I have over 1400 users. At first it appeared to work fine. But soon, we had complaints of students that couldn't retrieve their email. I looked in the logs and found this error.

[Dovecot] (somewhat ot?) purging old maildir messages
by Matt LaPlante 08 Jan '08

08 Jan '08

I'm using Dovecot (+postfix) to host some personal imap accounts on a private server (Maildir format). I've got one account that receives mostly automated mails, and I want to be able to purge messages beyond a given date (say 30 days). I know that since maildir uses flat files, I can literally just delete messages doing something similar to the following with bash: for i in $(find /var/spool/vmail/host1/user/cur/ -mtime +30); do rm $i done I dislike this approach for a few reasons. First, and most plainly, it seems crude. When running complex server software, its rarely a good idea in the field of systems administration to be bluntly deleting files out from under the running applications. It feels wrong. How does this affect dovecot's monitoring of the files and indexing? What if the files happen to be open in an email client? Etc. Emotions aside, I also very much dislike running an automated 'rm' that has the power to wipe out a lot of my email if something goes pearshaped with the script. I can think of several possible solutions that don't require subversive operations on the maildirs, but I've never used them and therefore don't know if they're actually feasible: - Use a tool designed to manipulate maildirs. Something akin to postfix's postqueue and postsuper tools come to mind, but I don't know if such an app exists. - Use a setting within dovecot that expires old maildir data. As I understand it this will be available in 1.1 (yay!); unfortunately that's not an option for me until 1.1 is available as stable in my server os. - Use a scriptable mua that has the capability to check mail under said account and automatically delete based on age. I know very little of tools in this area, so again I don't know if such an application exists. Any pointers you might have would be much appreciated. Thanks, Matt

[Dovecot] Problem with passwords surrounded by curly braces
by Frank Kintrup 08 Jan '08

08 Jan '08

Hello, one of my users set his password to something surrounded by curly braces, and promptly all access to his mailbox was refused. After looking through the logs I found an entry "Unknown password scheme xxxx", where "xxxx" is the user's password, but without the curly braces. I then browsed through the documentation and there was explained that it is possible to prefix the password with the password scheme in curly braces, like "{PLAIN}xxxx" where xxxx is the password itself. Manually altering the users password in the database to "{PLAIN}xxxx" (where "xxxx" is the user's password WITH curly braces) fixed this problem for me at this time, but the time a user chooses such a strange password I would have to edit the table again. So in my opinion the {SCHEME}-prefix is not a useful thing. Why would anyone need it, anyway? Shouldn't all passwords have the same scheme which is set in the dovecot.conf file once? If the feature is indeed used: with a database lookup it should be replaced by an optional database field or, if that's not possible, it should be possible to disable this feature from the config file.

[Dovecot] What would you tell the CIO in an "ABCs of Email" overview?
by Esther Schindler 07 Jan '08

07 Jan '08

One of the key points that came up when I researched and wrote the "Five Things CIOs Should Know about Fighting Spam" article (http:// www.cio.com/article/28830) was that they should know the basics of how email works. Otherwise, said plenty of techies, the CIO won't have the first idea of what the email admin is complaining about. So I'm going to do my part. I'm going to write an "ABCs of Email" article (to accompany the many other ABCs articles we have on CIO.com, at http://www.cio.com/article/40242 ). I'd like your input on the topics that should be included, keeping in mind the fact that the target reader is a CIO, IT manager, or someone who wants to understand the basics, *not* actively get involved in email management. You don't need to write an essay for me or inundate me with links (though hey, if you want to make my life easier I shall not complain). What I'm looking for, primarily, are the categories of information that I should cover. In other words, if your CIO had an email ephiphany and asked you to give a half-hour presentation, what would you include? This won't be an "Expert says..." article nor will it be "Geek on the street says...." I intend to compile and research the "least you need to know" for the not-necessarily-techie bosses out there. And hopefully the end result will be that you have one less dumb question to deal with in your life. So: any suggestions? (You can reply privately if you prefer.)

[Dovecot] v1.1.beta13 released

06 Jan '08

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta13.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta13.tar.gz.sig Changes since beta12: - Half of LDAP code was rewritten to fix reconnect/queuing problems. I did test that the new code works with and without auth binds, but be careful. - \Recent flags should finally work correctly with maildir. - last_used field wasn't updated for cache fields that were permanently cached. This caused them to be dropped after a month. TODO for RC1: - When pipelining commands, do only one sync after all of them. Besides improving performance, this fixes some rare problems when multiple commands are running simultaneously. - SEARCH/SORT: Replace invalid input with unicode "replacement character" instead of just skipping it. - Squat: Handle expunges. NFS support. - Fix Lucene support.

[Dovecot] Upgrading a live running dovecot - how?
by Daniel Watts 06 Jan '08

06 Jan '08

Hi Guys, This has bitten us twice now. We're running Gentoo and emerge (ie compile) a new version of Dovecot thinking we can finish that then restart Dovecot in our own time. It seems that Dovecot immediately starts to use the newly compiled Dovecot binary and we get version mismatch errors preventing access. Would be good if Dovecot behaved in such a way that it kept on using the old version (held in memory) until it was restarted where it then loaded the new version. Dan

I am not sure I have my sendmail.mc configured right, can someone confirm or give me some sample config files that make use of Dovecot+LDAP and sendmail LDA? Dovecot is running as root. I am a little confused, so the auth-master is not even needed? (the whole socket listen {}, since I am using static userdb and the user information was already found at authentication/login) Thank You! # 20080102: /usr/local/dovecot/etc/dovecot.conf listen: *:143 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/dovecot/var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/imap-login login_log_format_elements: user=<%n@%d> method=%m rip=%r lip=%l %c login_max_connections: 64 max_mail_processes: 128 mail_location: maildir:~/Maildir mail_debug: yes auth default: verbose: yes debug: yes passdb: driver: ldap args: /usr/local/dovecot/etc/dovecot-ldap.conf userdb: driver: static args: uid=vmail gid=vmail home=/var/mail/apps/%d/%n socket: type: listen master: path: /var/run/dovecot-auth-master mode: 384 user: vmail group: vmail My sendmail.mc file: define(`confFALLBACK_SMARTHOST', `mailhost$?m.$m$.')dnl define(`LOCAL_MAILER_PATH',`/usr/local/dovecot/libexec/dovecot/deliver') define(`LOCAL_MAILER_FLAGS',`DFMPhfnu9') define(`LOCAL_MAILER_ARGS',`deliver -d $u') MAILER(`local')dnl MAILER(`smtp')dnl LOCAL_NET_CONFIG R$* < @ $* .$m. > $* $#esmtp $@ $2.$m $: $1 < @ $2.$m. > $3

[Dovecot] FETCH for mailbox INBOX UID 39641 got too little data: 4823 vs 4825
by Mikhail Teterin 04 Jan '08

04 Jan '08

Whenever I try to access an e-mail in the middle (rather than at the end) of the mailbox, my mail-client (KMail) gets an error a message like this is logged in the maillog: IMAP(mi): FETCH for mailbox INBOX UID 39641 got too little data: 4823 vs 4825 IMAP(mi): Disconnected: Disconnected The actual numbers vary, but it is always X vs X+2 The problem started when I upgraded to 1.0.8. Unfortunately, it is still here with 1.0.9. The mailbox in question is the standard Unix mbox (/var/mail/mi in my case). The server runs FreeBSD/amd64. Please, advise. Thanks! -mi

[Dovecot] backup dovecot
by Nikolay Shopik 04 Jan '08

04 Jan '08

What is correct way to backup dovecot store? Is am I right what is just enough to copy all maildir and my configuration. So in case failure I can just prepare new machine copy config, maildirs and I'm good to go with this.

[Dovecot] Optimizing POP3 performance?
by Sebastian Färber 04 Jan '08

04 Jan '08

Hello, I recently migrated to Dovecot from Courier-IMAP and i'm very happy with the IMAP Performance and Dovecot in general. The server is running qmail-ldap and i'm still using the qmail pop3 daemon for the POP3 users. Because i want to get rid of qmail completely (switching to exim) i just tried to replace the qmail pop3 daemon with dovecot too. Immediately after the migration the server became basically unusable because of the high I/O Load caused by the dovecot pop3 daemon. I did some debugging and it looks like dovecot opens every old mail in a users maildir and wants to create it's index files etc. I tried running dovecot pop3 with and without "in memory" indexes but this didn't change anything. Is it possible to disable the indexing of the old e-mails completly for pop3? I understand that dovecot is primarily an IMAP Server but i didn't expect the POP3 Performance to be that bad compared to the qmail pop3 daemon (which is very very basic i have to admit). Is there anything i may have overlooked which helps with the POP3 Performance, any patches that disable the unnecessary indexing etc.? If not, what do you guys recommend and use as a pop3 daemon that is fast and stable? I'm using dovecot 1.0.2 (i checked the ChangeLog, doesn't look like upgrading would give better pop3 performance?) and the relevant pop3-config is: mail_location: maildir:~/Maildir:INDEX=MEMORY mail_debug: yes dotlock_use_excl: yes maildir_copy_with_hardlinks: yes mail_executable: /usr/local/dovecot/libexec/dovecot/pop3 mail_plugin_dir: /usr/local/dovecot/lib/dovecot/pop3 pop3_enable_last: yes pop3_uidl_format: %f pop3_client_workarounds: outlook-no-nuls oe-ns-eoh Any hint in the right direction is greatly appreciated Regards, Sebastian Faerber

[Dovecot] Homedir permissions problems with LDAP
by "Fábio M. Catunda" 04 Jan '08

04 Jan '08

Sorry, my previous message entered like a reply, so I'm sending again to keep the list in order. Hi, I'm using dovecot 1.0.5-1 (debian stable) and I'm trying to build a virtual host machine with ldap. In my dovecot-ldap.conf thats what I have: uris = ldap://<ldapserver>/ dn = cn=Manager, dc=domain, dc=com, dc=br dnpass = <ultra secret passwd> sasl_bind = no tls = no ldap_version = 3 base = ou=Users, dc=domain, dc=com, dc=br deref = never scope = subtree user_attrs = homeDirectory=homeDirectory user_filter = (&(mail=%u)) pass_attrs = mail=user,userPassword=password pass_filter = (&(mail=%u)) default_pass_scheme = CRYPT user_global_uid = 107 user_global_gid = 109 But I don't want to read homeDirectory from LDAP, so I have the following in dovecot.conf mail_location = maildir:/var/virtual/%d/%n/ The question is when I try to log into imap I receive the following error: dovecot: 2008-01-03 10:03:55 Error: IMAP(magalhaes(a)fmcs.com.br): mkdir(/HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB/expunged/cur) failed: Permission denied dovecot: 2008-01-03 10:03:55 Error: IMAP(magalhaes(a)fmcs.com.br): mkdir(/HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB/deleted/cur) failed: Permission denied dovecot: 2008-01-03 10:03:55 Error: IMAP(magalhaes(a)fmcs.com.br): mkdir(/HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB/deleted/expunged/cur) failed: Permission denied (I'm using lazy_expunge too) I can log in and etc, but this is strange for me, why do I receive this Permission denied message? The directory /var/virtual/<domain>/<user>/ is owned by uid 107 and gid 109, so, i believe thats ok. My homedir in ldap is /home/samba/<user> , so I changed tried to chown 107:109 too but I still get this error. Is there a way for me to know what is the full path that dovecot is trying to use? HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB is no helping me too much! Oh, I imagine that my lazy_expunge conf may be helpfull: namespace private { prefix = .EXPUNGED/ separator = / location = maildir:~/expunged hidden = yes } namespace private { prefix = .DELETED/ separator = / location = maildir:~/deleted hidden = yes } namespace private { prefix = .DELETED/.EXPUNGED/ separator = / location = maildir:~/deleted/expunged hidden = yes } Thanks for all!

[Dovecot] Compile error introduced in b13 (Solaris 10)
by mikkel＠euro123.dk 04 Jan '08

04 Jan '08

Any news on the b13 compile issue on Solaris 10 (both Sparc and X86)? Would be nice to know whether it's our own headache or something thats not supposed to be and thus expected to be fixed in the next release. Just to be clear this didn't occur in any other release (I've compiled all previous v1.1 betas on the same setup including b12).

[Dovecot] latest 1.1 betas and quota warning
by arvids 03 Jan '08

03 Jan '08

Hello, I noticed that quota warning is not executed with latest 1.1 betas and I looked at the code that implements quota warning. Here it is (line 657 in quota.c): if ((bytes_current < warnings[i].bytes_limit && bytes_current >= warnings[i].bytes_limit) || (count_current < warnings[i].count_limit && count_current >= warnings[i].count_limit)) { quota_warning_execute(warnings[i].command); break; } It seems to me that quota_warning_execute function will never be executed. Timo, can you look at this code? Regards, Arvids

[Dovecot] Building path to maildir
by Michel Bulgado 03 Jan '08

03 Jan '08

I have the following situation and I need help from all you people I have dovecot 0.99.11 and i want to migrate to a superior version like dovecot 1.0 looking forward to implement quotas in my system , and use the function deliver with postfix. My Scenario is as follow Dovecot + LDAP (ADS) + postfix My actual version is : 0.99.11 This is my actual configuration: Protocols = imap pop3 imap_listen = * pop3_listen = * login_dir = /var/run/dovecot-login login = imap login = pop3 default_mail_env = maildir:/var/spool/virtualmail/%d/%n mbox_locks = fcntl auth = dovecot-auth auth_mechanisms = plain auth_default_realm = CASA.CULT.CU auth_userdb = ldap /etc/dovecot-ldap.conf auth_passdb = pam dovecot auth_user = root auth_verbose = yes auth_debug = yes dovecot-ldap.conf hosts = ldap.casa.cult.cu base = ou=CASA,dc=casa,dc=cult,dc=cu dn = cn=unix-conector,cn=Users,dc=casa,dc=cult,dc=cu dnpass = ***** ldap_version = 3 deref = never scope = subtree user_global_uid = 500 user_global_gid = 500 user_attrs = mail,/var/spool/virtualmail/%d/%n,,,, user_filter = (&(objectClass=user)(!(objectClass=computer))(sAMAccountName=%n)) I see many changes in this new version. One of them is : -Renamed default_mail_env to mail_location - many changes in ldap queries With the new version my problem is when to dovecot tries to detect or builds the way where it´s stored the mailbox of my users. In /var/spool/virtualmail/%d/%u , it does not detect the domain when asking to my active directory (w2k) and consequently takes a value of my default realm = casa.cult.cu in this case the default domain where authenticate my users. My configuration in the new version of dovecot: protocols = imap pop3 protocol imap { listen = * } protocol pop3 { listen = * } login_dir = /var/run/dovecot/login login_chroot = yes login_greeting = Dovecot ready. mail_location = maildir:/var/spool/virtualmail/%d/%u mail_debug = yes mbox_read_locks = fcntl mbox_write_locks = fcntl protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } protocol lda { postmaster_address = postmaster(a)example.com mail_plugins = quota auth_socket_path = /var/run/dovecot/auth-master } auth_executable = /usr/libexec/dovecot/dovecot-auth auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb pam { args = dovecot } userdb ldap { args = /etc/dovecot-ldap.conf } userdb prefetch { } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = virtualmail group = virtualmail } } } dict { } plugin { quota = maildir:storage=10240 } user_attrs = mail,/var/spool/virtualmail/%d/%n,,,, The attribute mail in the old version returns to me user(a)casa.com or user(a)casa.cult.cu this way dovecot can build the way with no problems at all. But in this late version something is happening, it only takes the value %n= user , but not %d = domain . It´s not working. do you have any idea how I can solve this I beg your pardon for my poor English. ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

[Dovecot] dovecot-auth consumes 100% CPU time on Solaris 10
by KOT MATPOCKuH 02 Jan '08

02 Jan '08

Is problem with CPU load solved? I have same problem - dovecot-auth eats one of my cores. I'm using dovecot 1.0.7 on Solaris 10 Sparc. I tried to use auth-bind and standard scheme with separate user for bind and have same result. Problem occupts only with LDAP authentication, on some other systems I use PostgreQSL and MySQL authentication and doesn't have this problem. Using PAM authentication is not possible, because dovecot run in chroot'ed environment and I planing to move it to separate system or zone without ldap client. -- MATPOCKuH

[Dovecot] Delay on failed pw attempts
by Dean Brooks 02 Jan '08

02 Jan '08

Hi, Is there a way, or can a way be added, to add an "auth_failed_delay=10s" style option that would put in an artificial delay after a failed password attempt? As it stands now, Dovecot seems highly vulnerable to widescale brute-force password dictionary scans. Even if it's not configurable, can a delay be hardcoded to something like, say, 10 or 15 seconds? -- Dean Brooks dean(a)iglou.com

[Dovecot] deliver triggering SELinux AVC denials
by Gerry Reno 02 Jan '08

02 Jan '08

I setup postfix/dovecot on a new machine and now all works well with the small exception of dovecot triggering selinux avc denials on some temp... files here is a sample alert: Summary SELinux is preventing /usr/libexec/dovecot/deliver (dovecot_deliver_t) "link" to temp.localhost.678.40caaf5592891c46 (user_home_dir_t). Detailed Description SELinux denied access requested by /usr/libexec/dovecot/deliver. It is not expected that this access is required by /usr/libexec/dovecot/deliver and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for temp.localhost.678.40caaf5592891c46, restorecon -v temp.localhost.678.40caaf5592891c46 If this does not work, there is currently no automatic way to allow this access. Instead, you can generate a local policy module to allow this access - see http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.

[Dovecot] my.cnf reading support in MySQL backend
by Luca Longinotti 01 Jan '08

01 Jan '08

I hope this ml is the right place to send this... Anyway, I'd very much like for the MySQL backend to call mysql_options, so that it'll read the settings defined in MySQL's my.cnf under the [client] section. This allows to set a whole slew of MySQL specific settings for the MySQL connection, for example to enable the compressed protocol, set charsets, enable SSL client verification, and much more. A patch is attached that implements this. See http://dev.mysql.com/doc/refman/5.0/en/mysql-options.html for more info. -- Best regards, Luca Longinotti aka CHTEKK LongiTEKK Networks Admin: chtekk(a)longitekk.com Gentoo Dev: chtekk(a)gentoo.org SysCP Dev: chtekk(a)syscp.org TILUG Supporter: chtekk(a)tilug.ch

[Dovecot] deliver: keep existing From_ line
by Alexander 'Leo' Bergolth 01 Jan '08

01 Jan '08

Hi! I'm using procmail to filter my email. (I have to use it because of various features that are not supported by sieve.) However, I'd like to deliver mail to my mboxes using dovecots deliver program in order to update index files and speed up mbox access. Using "| $DELIVER -m <mboxname>" in my procmail receipes, everything works fine, except that the envelope sender address is mangled. deliver sets it to MAILER-DAEMON, even though it is already provided in the first line of the mail. I cannot use the "-f <address>" options of deliver, since procmail doesn't provide the envelope-sender address in a variable. (I'd have to extract it from the first line of the mail using a separate receipe, which isn't very efficient.) Is there a way to keep the already existing "From " line?

[Dovecot] Building path to maildir
by Michel Bulgado 01 Jan '08

01 Jan '08

Hello everyone Happy new year . This is the first time I address to the list I have the following situation and I need help from all you people I have dovecot 0.9-11 and i want to migrate to a superior version like dovecot 1.0 looking forward to implement quotas in my system , and use the function deliver with postfix. My Scenario is as follow Dovecot + LDAP (ADS) + postfix My actual version is : 0.99.11 This is my actual configuration: Protocols = imap pop3 imap_listen = * pop3_listen = * login_dir = /var/run/dovecot-login login = imap login = pop3 default_mail_env = maildir:/var/spool/virtualmail/%d/%n mbox_locks = fcntl auth = dovecot-auth auth_mechanisms = plain auth_default_realm = CASA.CULT.CU auth_userdb = ldap /etc/dovecot-ldap.conf auth_passdb = pam dovecot auth_user = root auth_verbose = yes auth_debug = yes dovecot-ldap.conf hosts = ldap.casa.cult.cu base = ou=CASA,dc=casa,dc=cult,dc=cu dn = cn=unix-conector,cn=Users,dc=casa,dc=cult,dc=cu dnpass = ***** ldap_version = 3 deref = never scope = subtree user_global_uid = 500 user_global_gid = 500 user_attrs = mail,/var/spool/virtualmail/%d/%n,,,, user_filter = (&(objectClass=user)(!(objectClass=computer))(sAMAccountName=%n)) I see many changes in this new version. One of them is : -Renamed default_mail_env to mail_location - many changes in ldap queries With the new version my problem is when to dovecot tries to detect or builds the way where it´s stored the mailbox of my users. In /var/spool/virtualmail/%d/%u , it does not detect the domain when asking to my active directory (w2k) and consequently takes a value of my default realm = casa.cult.cu in this case the default domain where authenticate my users. My configuration in the new version of dovecot: protocols = imap pop3 protocol imap { listen = * } protocol pop3 { listen = * } login_dir = /var/run/dovecot/login login_chroot = yes login_greeting = Dovecot ready. mail_location = maildir:/var/spool/virtualmail/%d/%u mail_debug = yes mbox_read_locks = fcntl mbox_write_locks = fcntl protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } protocol lda { postmaster_address = postmaster(a)example.com mail_plugins = quota auth_socket_path = /var/run/dovecot/auth-master } auth_executable = /usr/libexec/dovecot/dovecot-auth auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb pam { args = dovecot } userdb ldap { args = /etc/dovecot-ldap.conf } userdb prefetch { } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = virtualmail group = virtualmail } } } dict { } plugin { quota = maildir:storage=10240 } user_attrs = mail,/var/spool/virtualmail/%d/%n,,,, The attribute mail in the old version returns to me user(a)casa.com or user(a)casa.cult.cu this way dovecot can build the way with no problems at all. But in this late version something is happening, it only takes the value %n= user , but not %d = domain . It´s not working. do you have any idea how I can solve this I beg your pardon for my poor English. ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

[Dovecot] Maildir
by Peter Fraser 01 Jan '08

01 Jan '08

I have been trying to set up dovecot with postfix to use at work. I'm trying to configure dovecot to authenticate against active directory and postfix the same. I installed dovecot 1.0.10 on FreeBSD 7.0 beta 2 When I telnet in the get authentication ok but an error suggesting that there is no Mailbox belonging to that user. I am using Maildirs. How can I now create a Maildir with the proper permissions for that virtual user? Thanks for any assistance.

[Dovecot] Enhanced Kerberos support
by Richard A Nelson 31 Dec '07

31 Dec '07

The recent addition of auth_gssapi_hostname is a welcome addition, but a little more is needed for multi-homed (or multi-domained) sites. SSH recently added this enhancement to address this common need: GSSAPIStrictAcceptorCheck Determines whether to be strict about the identity of the GSSAPI acceptor a client authenticates against. If “yes” then the client must authenticate against the host service on the current hostname. If “no” then the client may authenticate against any service key stored in the machine’s default store. This facility is provided to assist with operation on multi homed machines. The default is “yes”. Note that this option applies only to protocol version 2 GSSAPI connections, and setting it to “no” may only work with recent Kerberos GSSAPI libraries. I've heard that other daemons support multi-names by instead of using gethostname(), obtain the hostname of the interface that the request came in on. Can either approach be looked at for dovecot ?

[Dovecot] Help with logging in and getting mail
by Andrew Falanga 31 Dec '07

31 Dec '07

Hi, Very new to dovecot and to using POP3/IMAP (from this perspective anyway). First things first, per the instructions from the web site: dovecot version: 1.0.5 dovecot config: # 1.0.5: /usr/local/etc/dovecot.conf protocols: imap pop3 ssl_disable: yes 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 verbose_proctitle: yes first_valid_gid: 0 mail_extra_groups: mail mail_location: mbox:~/mail/: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_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 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain digest-md5 user: vmail passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf Please help me diagnose what is causing the following problem. Essentially, this user is a virtual user. I have it so that the system user, vmail, is the basket into which all virtual users e-mail goes. If my understanding is correct (and please enlighten me if it's not), mail aliases are setup to "map" aliased names into a real account. From there, dovecot will return e-mail to the virtual user based upon the "To" field of the e-mail, correct? I have some aliases in my sendmail config that do just this. From the error below, it would seem that dovecot is actually authenticating the virutual user "jdunkin" in this case, but can't get some directories made. I've seen on my FreeBSD system that each system user has a "mail" file in the directory, /var/mail/<userid>. What needs to be done further? Also, how do I ensure that virtual users are able to get their mail as well as system users?

After reading of the problems encountered on other systems, the 1.1 beta 13 version (main part as well as Deliver) seems to inexplicably be running just fine under OS X 10.5.1 for some reason. :^) Jerry

[Dovecot] Time just moved backwards
by Neal Becker 31 Dec '07

31 Dec '07

This wins the 2007 award for strangest (or most amusing) log message: dovecot: Time just moved backwards by 13 seconds. This might cause a lot of problems, so I'll just kill myself now. It does, unfortunately, leave dovecot dead, which was pretty mysterious to me. Maybe it could re-exec instead?

[Dovecot] donations / wishlist
by Timo Sirainen 31 Dec '07

31 Dec '07

Since some people don't like Paypal and other people have been telling me for years to create Amazon wishlist, I figured I'd finally do it. http://dovecot.org/donate.html now contains URL to the wishlist. Currently it mostly contains all kinds of TV series DVDs (feel free to laugh at what I watch :), but I also managed to remember a couple of books I wanted.

[Dovecot] auth-master permission error

On F7, I get to where I have Postfix and Dovecot installed and configured, postfix check runs fine, but when I try to start Dovecot I'm getting a permission error. Here is the log entry: Dec 29 21:54:06 grp-01-50-90 dovecot: Dovecot v1.0.7 starting up Dec 29 21:54:06 grp-01-50-90 dovecot: Generating Diffie-Hellman parameters for the first time.

[Dovecot] building dovecot-sieve against installed dovecot
by Geert Hendrickx 30 Dec '07

30 Dec '07

Hi Timo, may I request once more to consider the attached patch for dovecot 1.1, it enables the sieve plugin (incl. sievec and sieved, needed for pysieved) to be built against an installed dovecot package, if --enable-header-install additionally installs the liblib.a library in the same directory as dovecot-config. I have included this patch in the pkgsrc dovecot 1.1 package a while ago. Geert

[Dovecot] global and per-users sieve filters

29 Dec '07

Hi Timo, I'm curious about such thing, currently if user have their own filter global filter no more take a place. Is this behavior changed in 1.1 or maybe in future? I'm unsure if this is 100 sieve related or more like Dovecot handling so fixing can be easily can done.

[Dovecot] v1.0.10 released
by Timo Sirainen 29 Dec '07

29 Dec '07

http://dovecot.org/releases/1.0/dovecot-1.0.10.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.10.tar.gz.sig v1.0.8 and v1.0.9 were a bit bad releases. Hopefully one day I've managed to have written a proper test suite which can be run before doing any releases.. * Security hole with LDAP+auth cache: If base setting contained %variables they weren't included in auth cache key, which broke caching. This could have caused different users with same passwords to log in as each other. - LDAP: Fixed potential infinite looping when connection to LDAP server was lost and there were queued requests. - mbox: More changes to fix problems caused by v1.0.8 and v1.0.9. - Maildir: Fixed a UIDLIST_IS_LOCKED() assert-crash in some conditions (caused by changes in v1.0.9) - If protocols=none, don't require imap executables to exist

[Dovecot] How to logoff a session with dovecot?
by Robin Atwood 29 Dec '07

29 Dec '07

I use dovecot to push email to my SE P1i and it works very well. :) However, I have two email accounts set up on the phone, one using my domain for GPRS and public WiFi and one using my WLAN address for use at home, the idea being I don't want to pay for GPRS data at home. The trouble is the GPRS account remains logged on and I get the mail in both inboxes. There is no option in the email client on the phone to disconnect, so is there any trick to forcing a disconnect from the mail server?

[Dovecot] Fishing attempt locking up dovecot
by Patrick Milvich 29 Dec '07

29 Dec '07

I've mentioned this before but only heard from one other person who has experienced this, but it's becoming a pretty serious issue. The situation: A spammer sets a bot on a fishing attempt to gain email addresses, causing numerous login processes to spawn and suck up all available resources. The problem: Obviously this can act like a dos attack, but the real issue is after the spammer stops (by virtue of being added to our firewall blacklist, being caught and shut down by their isp, or otherwise), dovecot doesn't seem to relinquish the resources, causing "too many files open" errors for normal usage. The master process usually hangs around 40-50 files open at any given time, with about 10,000 logins a day (I use: lsof -p `cat /var/run/ dovecot/master.pid ` | wc -l), after the attempt is over I always see the files open shoot up to near 3,000 without it able to go down until a dovecot restart. This usually happens about once a month, though we can get unlucky and have it happen a few days apart. I have some log excerpts below. Wondering if this is happening through my own fault or at least within my ability to alleviate the issue. Is there a way to limit the number of connections from an ip address? Has anyone used login_executable to first hit their own solution to keep track of, and implement connection restrictions similar to what I'm aiming for?

[Dovecot] v1.1.beta11 released

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta11.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta11.tar.gz.sig This one should be the last beta release before the first v1.1 release candidate. I'll try to stay away from this list and Dovecot in general for the next 1,5 weeks. I've several exams coming up and I should have started studying for them days ago already.. :) The main things left in my TODO are: - Squat indexes should handle expunges - Lucene indexes are broken - See if \recent flag handling could be fixed for maildir/mbox (it works for dbox though) - Some other minor things which I'll do if I have time, but won't block v1.1.0 release. Changes since beta10: - One major performance issue found and fixed. This was the main reason why we weren't yet in release candidate stage. - configure --with-package now gives an error if it can't find the necessary libs/headers for the package. Use --with-package=auto for the old behavior. - Memory leak fixes - Convert plugin fixes. Conversion is now done to namespace with INBOX. - Changes to handling group adding/removing to processes. Hopefully didn't break anything. - Message flag/keyword searches are now faster - Fixes/optimizations to handling SORT. After building initial indexes, my 260k mail mailbox sorts in about 0.01 seconds. :) - Fixes to searching mails with unknown charsets/invalid data - deliver_log_format setting

timo, i think i found a small problem with the ldap implementation: when using auth_bind (this might be in all conditions, not just that one - i haven't tested further), if the server lost connection to the ldap server (ie, the ldap server died) dovecot-auth would never reconnect to the ldap server and all subsequent auth attempts would fail. after a little more digging, i discovered that if the ldap server went down and came back up before the next dovecot request then everything would be fine. however, if a request came in while the ldap server was down then dovecot-auth would "cache" that the server was unavailable and never recheck it. i believe i tracked it down to a couple lines in db_ldap_bind and fixed it - dovecot-auth is reconnecting to ldap in the condition where it was not previously: --- dovecot-1.0.3/src/auth/db-ldap.c 2007-10-15 18:26:55.983349000 +0000 +++ dovecot-1.0.3/src/auth/db-ldap.c.new 2007-10-15 18:28:03.124136000 +0000 @@ -446,7 +446,10 @@ msgid = ldap_bind(conn->ld, conn->set.dn, conn->set.dnpass, LDAP_AUTH_SIMPLE); if (msgid == -1) { - db_ldap_connect_finish(conn, ldap_get_errno(conn)); + if (db_ldap_connect_finish(conn, ldap_get_errno(conn)) < 0) { + /* lost connection, close it */ + ldap_conn_close(conn, TRUE); + } i_free(ldap_request); return -1; }

[Dovecot] dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server
by Rolf E. Sonneveld 28 Dec '07

28 Dec '07

Hi, I'm new to the list; excuse me if this has been asked recently/before. running: # dovecot --version 1.0.8 Output of dovecot -n: base_dir: /var/run/dovecot protocols: none ssl_disable: yes login_dir: /var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/imap-login auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: ldap args: /usr/local/dovecot/etc/dovecot-ldap.conf userdb: driver: ldap args: /usr/local/dovecot/etc/dovecot-ldap.conf socket: type: listen client: path: /usr/local/postfix/spool/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot-auth-master mode: 438 Using dovecot only for the purpose of providing SMTP AUTH service for Postfix, using Active Directory (AD) as authentication source. As you can see from the config, connectivity between Dovecot and AD is implemented using LDAP. Contents of /usr/local/dovecot/etc/dovecot-ldap.conf (some site-specific info masqueraded): auth_bind = yes pass_filter = (sAMAccountName=%u) hosts = AD1.domain.com:3268 AD2.domain.com:3268 dn = CN=Service Account Postfix,OU=Services,DC=domain,DC=com dnpass = secret ldap_version = 3 base = DC=domain,DC=com scope = subtree Now, this works fine and authentication via SMTP AUTH + Dovecot works perfect. Yet, every 15 minutes I get the following warning in the syslog logfile: Dec 24 07:20:00 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server Dec 24 07:35:01 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server Dec 24 07:50:01 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server Dec 24 08:05:02 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server Dec 24 08:20:02 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server Dec 24 08:35:03 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server I've looked through the archives and it seems that this problem is caused by the fact that Dovecot (using the OpenLDAP client libraries?) keeps the LDAP connection open; after (in our case) 15 minutes Active Directory closes the connection and Dovecot signals this in the syslog (and presumably automatically will create a new connection to AD). I'm pretty sure that the OpenLDAP client libraries provide options to use a client-side timeout for LDAP connections. My questions are: * is there a reason that Dovecot wants to keep the LDAP connection open? * Will the new V1.1 version have a config parameter to set the LDAP client timeout or a default timeout value to close the connection? * If there's no 'fix' foreseen for V1.1, I'd like to file a request to add such a parameter. How can I file such a request? The warning is annoying; the sysadmin will create a filter, to filter the warning out from the syslog, but I'm afraid that if there's a real problem with authentication, that will be filtered too and the real problem is not noticed, before users start to complain. /rolf

Re: [Dovecot] namespace problem / 1.1beta11
by ja nein 28 Dec '07

28 Dec '07

Hi Timo, I think I've hit a separator bug: This is namespace query of dovecot and source server: ---snip--- * OK Dovecot ready. 1 login ... 1 OK Logged in. 2 NAMESPACE * NAMESPACE (("INBOX/" ".")) NIL NIL 2 OK Namespace completed. 3 logout * BYE Logging out 3 OK Logout completed. Connection closed by foreign host. Escape character is '^]'. * OK [CAPABILITY IMAP4 IMAP4rev1 LITERAL+ ID STARTTLS AUTH=CRAM-MD5 AUTH=DIGEST-MD5 AUTH=NTLM AUTH=SRP AUTH=OTP AUTH=PASSDSS-3DES-1 SASL-IR] Cyrus IMAP4 v2.3.8 server ready 1 login ... 1 OK [CAPABILITY IMAP4 IMAP4rev1 LITERAL+ ID LOGINDISABLED ACL RIGHTS=kxte QUOTA MAILBOX-REFERRALS NAMESPACE UIDPLUS NO_ATOMIC_RENAME UNSELECT CHILDREN MULTIAPPEND BINARY SORT SORT=MODSEQ THREAD=ORDEREDSUBJECT THREAD=REFERENCES ANNOTATEMORE CATENATE CONDSTORE IDLE LISTEXT LIST-SUBSCRIBED X-NETSCAPE URLAUTH] User logged in 2 NAMESPACE * NAMESPACE (("INBOX/" "/")) (("user/" "/")) (("" "/")) 2 OK Completed 3 logout * BYE LOGOUT received ---snip--- So Dovecot is stating Namespace separator is ".". But my dovecot -n namespace section shows: namespace: type: private separator: / prefix: INBOX/ inbox: yes list: yes subscriptions: yes According to this I've set separator to "/". And this is the problem. I think problem arised somewhere between beta9 and beta11, as it worked before... The separator in imapsync was for both "/" (--sep1 /, --sep2 /), I just played with all possibilities... Well, never mind if v1.2 or v2.0, as long as LMTP makes it in ;) Anyway, we can provide some good stress testing in such an environment... Regards and for all Merry Christmas and a happy new year!

Forwarding all mail to a SMTP server on the machine running dovecot and doing delivery there isn't the favoured option (at least for us). Yes, LMTP would be nice, but it pretty much requires v2.0 framework. I'm still not sure if the next version will be v1.2 or v2.0.. Jetzt Mails schnell in einem Vorschaufenster überfliegen.

If you need I can try and reproduce this in a more controled environment to pinpoint the problem. Thanks, -- Nuno Lopes

[Dovecot] Dovecot + Cygwin the 2nd
by Ronny 28 Dec '07

28 Dec '07

Hi, i still try to get dovecot to run under cygwin. After a post on the cygwin list i am able tu run dovecot. Under Cygwin you have to run dovecot by inetd. Starting the binary "dovecot.exe" does not work. Well the server is running but answers with a fatal error. Account: 'localhost', Server: 'localhost', Protokoll: POP3, Serveranswer: 'Fatal: EOF while reading environment from master', Port: 110, Secure (SSL): No, error on server: 0x800CCC90, Fehlernummer: 0x800CCC90 This error is from Outlook, Thunderbird just says there is an error without any error message. So maybe you can help me to bring my story to a hapy end ;-) Cheers Ronny

My problem is the per user quota, if i want give some user, more or minus space, i'm not able to do this. I've added a quota field to the mysql that read dovecot, but i don't know ho to read this in dovecot-mysql.conf. Someone can help me? Thanks

[Dovecot] v1.1.beta12 released
by Timo Sirainen 25 Dec '07

25 Dec '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta12.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta12.tar.gz.sig Still not a release candidate, maybe the next one.. This release fixes a lot of bugs and adds some new sanity checks. Fixes quite a lot of mbox problems. v1.1.beta11 (no other versions) had a potential security hole where memory was free()d multiple times. \Recent flags should work perfectly now with mbox. Still somewhat broken with maildir.

[Dovecot] Brute Force Blocking?
by Ben Cadieux 24 Dec '07

24 Dec '07

Hi Everyone, Before I begin, I'd just like to mention: I love dovecot. Thank you :) Anyway, today I had 8000 login attempts to my dovecot server in an hour before blocking the IP with my firewall. After googling, I didn't see very much discussion on the topic. There was some mention of blocksshd which was supposed to support dovecot in the next release (but doesn't appear to) and also fail2ban. While a script that parses logfiles will work, I'm not sure that this is the best way to go about handling repeated authentication failure. Would it not be best built into dovecot? Are there any plans for this? Best Regards, Ben Cadieux

[Dovecot] Compact all maildirs with dovecot-1.0.9?
by Jeff Kowalczyk 23 Dec '07

23 Dec '07

I'm running dovecot-1.0.9 on Gentoo Linux. I recently observed a large increase in disk usage on this dedicated mailserver. I attribute it to high spam traffic and/or large attachments for legit email retained on the server. How can I run a command equivalent to an IMAP client's 'Compact Folder' on the entire tree of maildirs under each /home/(user)? Thanks.

[Dovecot] Squirrelmail + Dovecot + Maildir
by Vicki Stanfield 21 Dec '07

21 Dec '07

I have been struggling with getting my Fedora 7 box set up to use dovecot with Squirrelmail and Maildir. It works correctly with the exception of writing outgoing mail to the right folder (.Sent) or drafts (.Drafts). If I send a mail with Mutt, it writes the mail to the right place, so it has to be squirrelmail config or dovecot config. I want to use .Sent for sent-mail (~user/Maildir/.Sent) and .Drafts for drafts (~user/Maildir/.Drafts). Here is what I see in /etc/squirrelmail/config.php $optional_delimiter = '.'; [snip] $default_folder_prefix = ''; $trash_folder = 'Trash'; $sent_folder = 'Sent'; $draft_folder = 'Drafts'; $default_move_to_trash = true; $default_move_to_sent = true; $default_save_as_draft = true; The error in the browser is: * ERROR : Bad or malformed request.* Server responded: {830} BAD Error in IMAP command : Unknown command. and in the logs I see this: Dec 18 09:41:56 opus postfix/smtpd[12747]: connect from localhost[127.0.0.1] Dec 18 09:41:56 opus postfix/smtpd[12747]: 4CB7329B00B2: client=localhost[127.0.0.1] Dec 18 09:41:56 opus postfix/cleanup[12750]: 4CB7329B00B2: message-id=<51150.127.0.1.1.1197988916.squirrel(a)127.0.1.1> Dec 18 09:41:56 opus postfix/qmgr[2650]: 4CB7329B00B2: from=<vic(a)thepenguin.net>, size=1015, nrcpt=1 (queue active) Dec 18 09:41:56 opus postfix/smtpd[12747]: disconnect from localhost[127.0.0.1] Dec 18 09:41:56 opus dovecot: imap-login: Login: user=<vic>, method=PLAIN, rip=::ffff:127.0.1.1, lip=::ffff:127.0.1.1, secured Dec 18 09:41:56 opus dovecot: IMAP(vic): Disconnected: Too many invalid IMAP commands.

[Dovecot] namespace problem / 1.1beta11
by ja nein 21 Dec '07

21 Dec '07

Hi all, actually I got a problem with the namespaces in dovecot 1.1 beta11. It occured after purging index files and resynch via imapsync. Dovecot complains about "Unknown namespace", though it worked with versions before. I cannot comfirm for 1.1beta10, but I surely know 1.1beta9 worked with these settings. Example: From Folder [INBOX/Trash] To Folder [___________] To Folder ___________ does not exist Creating folder [___________] Couldn't create [___________]266 NO Unknown namespace. Used imapsync command: /home/imapsync/imapsync --host1 ip.of.host.1 --user1 user1 --password1 password --host2 127.0.0.1 --user2 user2 --password2 password --authmech2 LOGIN --regextrans2 s/\./_/g --delete2 --sep1 . --sep2 . --justfolders Another run with different namespace settings shows up the folders in Thunderbird as INBOX^2002, INBOX^Trash ans so on... My goal is to keep all client settings when migrating a bigger installation of cyrus to dovecot. For know all folders in Cyrus appear as subfolders of INBOX, which I had achieved with dovecot < 1.1beta11. Any ideas? Btw., as we work in a load balanced environment, LMTP delivery would be a great feature for upcoming releases, as it would enable people to use multiple frontends of SMTP servers without the need of connecting them to a somewhat shared file system. Forwarding all mail to a SMTP server on the machine running dovecot and doing delivery there isn't the favoured option (at least for us). And a huge thx to Timo on working that hard on such a great working product!

[Dovecot] Dovecot truncating messages and/or attachments
by fp＠kraptastic.com 21 Dec '07

Hello, I am having problems with Dovecot not sending clients emails bigger then 8-12k (it varies) or attachments bigger then 8-12k. I am also getting 'Corrupted transaction log file' errors ' unexpected end of file while reading header' I have deleted the dovecot.index.log, dovecot.index.cache, and dovecot.index several dozen times.

So it does not appear to be a permission problem, it is reading and writing to the directory properly. The system is x86_64 centos 5, not using the standard dovecot nor postfix rpms that come with the distro. postfix from what I can tell, is working fine, but dovecot isn't. I'm going to try installing cyrus to make sure it's not postfix, but I'd really like to avoid cyrus if possible. Thanks in advance for any help.

[Dovecot] about quota_warning behavior
by naoki 21 Dec '07

21 Dec '07

Hi, We've been using v1.0.5 +quota_warning patch, however quota_warning does't seem to be working properly. For example, in order to enable 80% over for quota warning, and we configured like following: ----------------------------------------------------------------------- plugin { quota_warning = storage=80%% /usr/local/path/to/plugin } ----------------------------------------------------------------------- But it does not work. However we set quota_warning value to 20%, it seems to be working. ----------------------------------------------------------------------- plugin { quota_warning =storage=20%% /usr/local/path/to/plugin } ----------------------------------------------------------------------- If this is the case, do we always have to set quota value to what we have after subtracting the required quota warning value from 100. for example, if we want quota warning value to be 70%, we actually have to write 30% in configuration?? Will there be another patch to fix this? Thanks -- Naoki Takazawa Marino Ltd., Yokohama, JAPAN

Re: [Dovecot] 1.1.Beta9 deliver problem: Unknown mail storage driver raw
by ja nein 21 Dec '07

Hi Velko, I recently hit the same problem. You have to add raw storage driver to your compile options, meaning "--with-storages=maildir,mbox,dbox,raw,cydir", that will do the trick. Maybe it would be good to update the description of available storage drivers in configure script.

[Dovecot] 1.1 beta 11 - no quota warnings
by adam_jh＠hotmail.com 21 Dec '07

21 Dec '07

Having tried and failed to get 1.0.8 with quota-rewrite to send warnings, I removed the 1.0.8 and installed the latest 1.1 - however I still can't get the warnings! Can someone advise what might be wrong - it must be my configuration?? To compile 1.1 I used ./configure --with-deliver --with-mysql. I've chopped and changed my conf till I'm blue in the face. My dovecot-mysql.conf file does not override the quota, I've enabled the debug and verbose = yes - but they don't mention any quota warnings, just normal delivered logs. What else can I do? The process I use is to add up the maildirsize totals, set a storage figure in the conf which makes the maildirsize just less than 95%, then restart dovecot, send an email - and nothing - no warning is triggered! Any help appreciated - I've spent so long on this now. adam # 1.1.beta11: /usr/local/etc/dovecot.conf protocols: imap imaps pop3 pop3s ssl_disable: yes 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 mail_extra_groups: mail mail_location: maildir:/var/vmail/%d/%n 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_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota 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 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: user: nobody verbose: yes debug: yes passdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf userdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth user: postfix group: mail master: path: /var/run/dovecot/auth-master user: vmail group: mail plugin: quota: maildir quota_rule: *:storage=220000b quota_warning: storage=95%% /usr/local/bin/quota-warning 90

[Dovecot] imap+unix users and pop3+virtual users
by Wendell Turner 21 Dec '07

21 Dec '07

This should be simple, but I'm missing something. My virtual users cannot access their mail. I would like Unix users to get their mail via imap which is deposited in /var/spool/mail/username. (This works.) I would like virtual users to get their mail via pop3 which is deposited in /var/spool/mail/vhosts/example.com/auser/mail/inbox (postfix does in fact put the mail there). Those users can get authenticated via file /var/dovecot/passwd, but cannot retrieve their mail. The log message is shown below. The file/directory is there, but doesn't dovecot see it? Thanks, Wendell -------------------- Info: POP3(auser(a)example.com): mbox: data=/var/spool/mail/vhosts/example.com/auser/mail/:INBOX=/var/mail/auser@e… Info: POP3(auser(a)example.com): mbox: root=/var/spool/mail/vhosts/example.com/auser/mail, index=/var/spool/mail/vhosts/example.com/auser/mail, inbox=/var/mail/auser(a)example.com Info: POP3(auser(a)example.com): Mailbox init failed top=0/0, retr=0/0, del=0/0, size=0 -------------------- /usr/sbin/dovecot -n # 1.0.7: /etc/dovecot.conf log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log protocols: pop3 imap imaps pop3s ssl_cert_file: /etc/CA/cert.pem ssl_key_file: /etc/CA/key.pem login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_location: mbox:~/mail/:INBOX=/var/mail/%u mail_debug: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: pam passdb: driver: passwd-file args: /etc/dovecot/passwd userdb: driver: passwd userdb: driver: static args: uid=vmail gid=vmail home=/var/spool/mail/vhosts/%d/%n

[Dovecot] upgrade to 1.1 and mail location
by lenny＠edpausa.com 21 Dec '07

21 Dec '07

I recently upgraded from 1.0.8 to 1.1-11 the only thing that was changed in the config file was the new syntax for mail location. default_mail_env = mbox:~/:INBOX=~/mbox to mail_location = mbox:~/:INBOX=~/mbox now some imap clients, like squirrellmail and pine have difficulties writting to Sent, Draft and sent-mail folders. In all cases the folders are visible and are present in .subsriptions file( although not seen as subscribed in squirrelmail), but the clients complain that folders already exist when trying to write to them after sending. has anyone run into this ? any suggestions ? thanks a lot.

Hello, when dovecot is started, it prints the following error to the console: ILoading modules from directory: /usr/local/dovecot/lib/dovecot/imap IModule loaded: /usr/local/dovecot/lib/dovecot/imap/lib10_quota_plugin.so IEffective uid=65534, gid=65534, home= Idict quota: user = dump-capability, uri = proxy:/var/run/dovecot/dict-server:quotadict Enet_connect_unix(/var/run/dovecot/dict-server) failed: Connection refused It seems that problem is that dict server is not started yet. Later everything seems to be OK, so it is more cosmetic issue.

[Dovecot] minor issue - dovecot -n output with 1.1.beta11
by arvids 21 Dec '07

21 Dec '07

Hello, when running diff for 'dovecot -n' outputs from beta10 and beta11(for the same config file), I noticed that 'dovecot -n' beta11 output does not show anymore the following parameters, which are set to non-default values(and which 'dovecot -a' shows): login_processes_count login_max_processes_count first_valid_uid first_valid_gid cache_size cache_ttl cache_negative_ttl mode(from auth default section) And by the way, parameters from lda section are not showed both with -a and -n. But it is so already for a long time, so I assume that it is OK :) Regards, Arvids

I have just installed my mail server on a Ubuntu Linux V.7.10 box with sendmail and dovecot imap from the Ubuntu packages. Each time the machines boots, I get the following messages: Starting mail server: dovecotWarning: Fixing permissions of /var/run/dovecot to be world readable Warning: Corrected permissions for login directory /var/run/dovecot/login After the boot the permissions visible are: drwxr-xr-x root root /var/run/dovecot drwxr-x--- root dovecot /var/run/dovecot/login What permissions do I need to set so that the warnings do not appear?

[Dovecot] Dirsize quotas with 1.1beta9
by Dean Brooks 21 Dec '07

21 Dec '07

Hi, Anyone able to get 'dirsize' quotas to work properly under 1.1beta9? I can get them to reflect the size of the INBOX properly, but it never seems to be adding up the size of the files in the folder directory itself. I'll keep hammering away at it if others are able to use dirsize with no problems, but wanted to check first. -- Dean Brooks dean(a)iglou.com

[Dovecot] Security hole #4: Specific LDAP + auth cache configuration may mix up user logins
by Timo Sirainen 21 Dec '07

21 Dec '07

Somehow I doubt there are any Dovecot setups left that unknowingly have this problem, but it still counts as a security hole. The possibility to cause this problem exists in Dovecot v1.0.rc11 and later. If you use: 1. passdb ldap with settings: - auth_bind = yes - auth_bind_userdn = no - base containing %variables required for unique user identification, e.g. base = dc=%d,dc=org - pass_filter not containing all %variables required for unique user identification - pass_attrs returning user-specific settings, such as user's home directory 2. userdb prefetch 3. auth_cache_size non-zero (0 is default) If two users with the same password and same pass_filter variables log in within auth_cache_ttl seconds (1h by default), the second user may get logged in with the first user's cached pass_attrs. For example if pass_attrs contained the user's home/mail directory, this would mean that the second user will be accessing the first user's mails. You most likely would have noticed this already by wondering why logins keep failing, unless pass_filter used also some %variables that most of the time uniquely identifies the user. For example %r (remote IP address) or %n (username without domain). You can fix this by upgrading to v1.0.10 (to be released soon), or using this patch: http://hg.dovecot.org/dovecot-1.0/raw-rev/2cedab21cd6d

[Dovecot] dovecot-auth: returning incorrect maildir for user (user seeing another user's mail)
by Brendan 20 Dec '07

20 Dec '07

timo, here is an bizarre bug for you: i had (foolishly, it turns out) configured dovecot-auth to do ldap authentication binding with a prefect userdb (configs at end of message). everything worked fine, although with huge numbers of pop logins per second we started to see some pileup in the pop3-login processes as they were all waiting for ldap responses on the single ldap connection. the auth caching was never getting hit (some interaction with the prefetch, i assume), but everything worked fine. or so i thought. we had complaints from a user saying they would occasionally pop another user's mail. after much digging, it turned out that if two or more users: - were logged/logging in at the same time - had the same password - got "lucky" then one of the users would occasionally end up with the other users' homedir/maildir. it didn't happen often (maybe once every 500-1000 login attempts), but it did happen. (i ended up writing a script that would pound the pop3 server with logins and look for the wrong number of messages in the inbox. it was not easy to trigger). i'd already realized that having the auth bind do a search and return that to prefetch was a bad idea (since it used a single ldap connection) and had already built a new config that used auth binding and userdb ldap - when we switched over to that config we were unable to replicate the problem again. so, it's not an issue for us right now. i've confirmed that the ldap server never returns the wrong homedir, so it must have been getting mixed up somehow in dovecot-auth. but it did seem like something you might want to dig into a bit, as it might indicate that something could be amiss somewhere in the auth code. that the problem only occured when the users had the same password seemed truly bizarre.. sorry i can't provide more details, it was very difficult to reproduce (and i was reproducing in a production environment and couldn't turn debug up). the auth section from the poorly behaving dovecot.conf: auth default { mechanisms = plain login passdb ldap { args = /opt/dovecot-1.0.3/etc/dovecot-ldap.conf } userdb prefetch { } user = mail } the poorly behaving dovecot-ldap.conf: hosts = ldap ldap_version = 3 auth_bind = yes base = uid=%u,o=imap user_global_uid = 8 user_global_gid = 8 dn = uid=imap@dovecot,o=imap dnpass = ****** pass_filter = (&(proto=%s)(remoteip=%r)(localip=%l)(mech=%m)(pid=%p)) pass_attrs = home=userdb_home,quota=userdb_quota,nologin=nologin,reason=reason,user=user note: the ldap server does some custom processing based on the filter - the filter was the easiest way to get them passed to it. (in case that looks a little wierd :)

Any suggestions as to what license to use for wiki.dovecot.org? I should have specified this a long time ago, but luckily(?) most of the content is written by me, so I don't think there are going to be problems. The main choices are: a) GNU Free Documentation License b) Creative Commons (Attribution-Share Alike?) It could also be dual-licensed to both to maximize the distribution possibilities.
