[Dovecot] Message flags
by Ralf Hildebrandt 30 Aug '11

30 Aug '11

How do I set message flags in sieve rules in such a way that e.g. Thunderbird is displaying the mail as "important"? Is there a list of hwo flags are interpreted by different IMAP clients? -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] Sub-folder outside of the mail store
by Simon Brereton 30 Aug '11

30 Aug '11

Hi How do I create an IMAP folder that links to a folder outside of the mail store? For example, I have all domains under /var/spool/mail/virtual/domains.net/ and users under /var/spool/mail/virtual/domains.net/user Amavis delivers quarantine mail to /var/spool/mail/quarantine I would like one user (postmaster) to have a folder /var/spool/mail/virtual/domains.net/postmaster/.Quarantine and link it to that folder - is that possible? Is it safe? The client the postmaster uses can then reinject and deliver the mail if need be (i.e. it's safe or the attachment has been stripped). Thanks. Simon

[Dovecot] ldap authentication
by Daminto Lie 30 Aug '11

30 Aug '11

Hi, I have got Postfix, Dovecot IMAP and squirrelmail up and running on my ubuntu server 10.04 for a testing purpose. My question is in order to be able to login, do I need to create user accounts for each users on the server? I have about 20 users at the moment, and it's going to take time. I was thinking of using LDAP and have the dovecot authentication through LDAP. This way, I do not have to create accounts for 20 users on the server. The dovecot can just authenticate users by looking them up against the LDAP. I wonder if anyone would be able to share some guides as to how to set it up to work with Postfix and Dovecot. Thank you

[Dovecot] dovecot w/ libwrap on fbsd

Dovecot with libwrap doesn't work on FreeBSD for some reason or another. I have these lines in my /etc/hosts.allow: ALL: LOCAL 127.0.0.1: allow pop3: ALL: allow ALL: ALL: deny Yet when you try to telnet to localhost, port 110 this is what happens: Aug 29 22:48:38 dodo dovecot: pop3-login: Error: connect(tcpwrap) failed: Permission denied I also tried auth_debug=yes to see what's wrong but it only shows the processes which handled the connection, no extra info with the reason why it failed.

[Dovecot] : error while loading shared libraries: libdovecot.so.0 (arm cross compile)
by Stephen Feyrer 29 Aug '11

29 Aug '11

Hi. I've made a new attempt at build Dovecot. The build and then install processes appeared to work find. Then when I try to run Dovecot it reports the error: /share/MD0_DATA/optware/opt/sbin/dovecot: error while loading shared libraries: libdovecot.so.0: cannot open shared object file: No such file or directory To get a better idea of what's going on, I added --enable-devel-checks at ./configure and then ran gdb: # gdb --args dovecot -F GNU gdb 6.8 [snip] This GDB was configured as "arm-none-linux-gnueabi"... (no debugging symbols found) (gdb) run Starting program: /share/MD0_DATA/optware/opt/sbin/dovecot -F (no debugging symbols found) /share/MD0_DATA/optware/opt/sbin/dovecot: error while loading shared libraries: libdovecot.so.0: cannot open shared object file: No such file or directory Program exited with code 0177. (gdb) bt full No stack. (gdb) quit By the way on a separate but related note, adding --enable-maintiner-mode introduced a new problem also relating to libdovecot.so.0.0.0 I'll refer to that in the post script. # ls -alh

If I manually change the permission (to 0660) then I can see the mail in the MUA. If /var/spool/mail/virtual/domain.net/simon has 0770 permissions, the new mails should be delivered with 0660 permissions. (I don't remember if having g+s makes any difference in the directory like you have in the domain dir.) In any case, it would be better if mails were delivered as mailsystem:mailsystem 0600 since that's what you're reading them as. Unless you have some other good reason for requiring mailsystem group to be able to read them.

Re: [Dovecot] File Permissions and delivery
by Patrick Domack 29 Aug '11

My guess is your delivering email with postfix to the inbox, instead of using dovecot-lda. And something odd is going on with that postfix to get odd permissions like that. You probably needed to edit the postfix virtual deliever transport, or maybe you just forget to active the dovecot-lda (deliever) transport.

[Dovecot] limiting number of incorrect logins per connection
by Alex 29 Aug '11

29 Aug '11

Hi Guys, Running Dovecot 2 on my server. It is regularly getting dictionary auth attacked. What I have noticed is that once connected to a pop3/imap login session, you can send endless incorrect usernames+passwords attempts. This is a problem for me... I use fail2ban to try and stop these script kiddies. The problem is that fail2ban detects the bad auths, firewalls the IP, however, since it's an "established" session, the attacker can keep authing away... It's only on a subsequent (new) connection that the firewalling will take effect. Why is there no configuration option such as "max auth attempts per connection"? This would be useful, so once the limit is reached, the connection is dropped. is there a patch/workaround?

Re: [Dovecot] Catch22: user needs space to fix out of space condition
by Joseph Tam 29 Aug '11

Thanks to all who've made suggestions. It seems removing dotlocks as a locking method is the way to go. There is another dotlock locking variant mentioned in 10-mail.conf that seems to address this situation for those that can't get away from dotlocks: # dotlock_try: Same as dotlock, but if it fails because of permissions or # because there isn't enough disk space, just skip it. mbox_write_locks = dotlock_try fcntl Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] v2.0.14 released
by Timo Sirainen 29 Aug '11

29 Aug '11

http://dovecot.org/releases/2.0/dovecot-2.0.14.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.14.tar.gz.sig It's been a while since the previous release.. I've been a bit busy with my newly created Dovecot support company, but it was also summer and I wasted some time doing nothing useful. :) Most of my recent time has gone to adding new features to v2.1 branch. I'm planning on releasing v2.1.alpha1 somewhat soon and the final v2.1.0 sometimes later this year. This v2.0.14 release also contains one larger new feature: Ability to list and kick imap/pop3 proxy connections. This is done via a new "ipc" process where all proxying login processes connect to, which allows doveadm to communicate with them. If you're not using these features, this change (and its potential bugs) should be pretty much invisible. BTW. I know there are still mails I haven't read & replied to. I'll try to get to them eventually, but you may as well re-send anything you want me to read sooner rather than 6 months from now. Some of the largest changes since v2.0.13: + doveadm: Added support for running mail commands by proxying to another doveadm server. + Added "doveadm proxy list" and "doveadm proxy kick" commands to list/kick proxy connections (via a new "ipc" service). + Added "doveadm director move" to assign user from one server to another, killing any existing connections. + Added "doveadm director ring status" command. + userdb extra fields can now return name+=value to append to an existing name, e.g. "mail_plugins+= quota". - script-login attempted an unnecessary config lookup, which usually failed with "Permission denied". - lmtp: Fixed parsing quoted strings with spaces as local-part for MAIL FROM and RCPT TO. - imap: FETCH BODY[HEADER.FIELDS (..)] may have crashed or not returned all data sometimes. - ldap: Fixed random assert-crashing with with sasl_bind=yes. - Fixes to handling mail chroots - Fixed renaming mailboxes under different parent with FS layout when using separate ALT, INDEX or CONTROL paths. - zlib: Fixed reading concatenated .gz files.

[Dovecot] unlink_directory failed with 'Device or resource busy' on NFS

Hi, I'm getting some errors while I'm trying to move mailboxes from IMAP server to Outlook client. The error message is "IMAP command is failed" and I think it is useless. Here are the error messages written to server's syslog. imap(name(a)domain.com<mailto:name@domain.com>): Error: unlink_directory(/data/domain.com/name/INBOX/direct/.nfs00000000000033fd000… failed: Device or resource busy imap(name(a)domain.com<mailto:name@domain.com>): Error: unlink_directory(/data/domain.com/name/INBOX/IDC/.nfs000000000000709d000000… failed: Device or resource busy imap(name(a)domain.com<mailto:name@domain.com>): Error: unlink_directory(/data/domain.com/name/INBOX/OSSEC/.nfs000000000000709f0000… failed: Device or resource busy How can I solve this problem?

[Dovecot] Pop3 hanging up after login.
by Fabio Catunda 29 Aug '11

29 Aug '11

Hi, I'm trying to implement a second dovecot server on a second machine to try to load balance IMAP/POP3 services. The first machine is already running and is working pretty well with dovecot-pop3d 1:1.0.15-2.3+lenny1. The new machine is running dovecot-pop3d 1:1.2.15-7 and accessing the existing maildirs over a NFS share on /mnt/mail. When I try to telnet localhost 110 on the new machine it just freezes after the "pass MySecret", like this: # telnet localhost 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Bem Vindo. user my.user(a)mydomain.com.br +OK pass MySecret ... (Nothing else happens) If I try to stop Dovecot with /etc/init.d/dovecot stop it stops, but the pop3 process keep running and the only way to stop it is with kill -9. On my log I only can see this: Aug 27 15:03:40 radamante dovecot: auth(default): client in: AUTH#0112#011PLAIN#011service=pop3#011secured#011lip=127.0.0.1#011rip=127.0.0.1#011lport=110#011rport=60421#011resp=<hidden> Aug 27 15:03:40 radamante dovecot: auth-worker(default): pam(my.user(a)mydomain.com.br,127.0.0.1): lookup service=dovecot Aug 27 15:03:40 radamante dovecot: auth-worker(default): pam(my.user(a)mydomain.com.br,127.0.0.1): #1/1 style=1 msg=Password: Aug 27 15:03:42 radamante dovecot: auth-worker(default): pam(my.user(a)mydomain.com.br,127.0.0.1): pam_authenticate() failed: Authentication failure (password mismatch?)

[Dovecot] occasional dovecot crash, core captured but no symbol table info?

Dovecot is crashing occasionally for me.

Thanks for that. I will change it and recompile. Sorry for the grumpyness yesterday in my posts. Was having a bad day. Is there any chance of there being an option on future versions that allow a number of failed auth attempts to be specified before dropping the connection? The other thread you mentioned, I see someone devised a small patch in c to add this functionality. It didnt look like a lot of code to do it.

Re: [Dovecot] On IMAP vhost login, only Username being used

Found it. :) Not a dovecot problem but a field in Icedove (Thunderbird variant) that had been automatically filled in by the software "to serve you better". It's on the Server Settings page as "User Name". "Never mind..." :) --hobie > Recapping: I'm working to set up Dovecot 2.0.13 along with some additional software (qmail, vpopmail, squirrelmail).

[Dovecot] performance with 100k messages per folder
by Florin Andrei 26 Aug '11

26 Aug '11

dovecot-2.0-0.10.beta6.20100630.el6.x86_64 on CentOS 6. Virtual machine with 1 GB of RAM on VMWare. The configuration is more or less stock. Postfix receives then delivers to Dovecot. IMAP with mbox. Only one user account, but shared by several people via webmail (Roundcube webmail in Apache on the same machine). No other MUAs. 100k new messages per month, inbox is rotated monthly into a YYYYMM folder by a cron job. Only one monthly folder so far. Messages are never deleted (but I may start deleting old folders a year or two from now). This is mostly for reading, with occasional messages being forwarded. The email was pretty sluggish when logging in to the webmail interface. I asked the admin to increase the RAM from 0.5 to 1 GB. I changed mbox_very_dirty_syncs to yes. These measures seemed to accelerate it a lot. There's still a 1 sec pause when logging in, during which time the dovecot/imap process is using a lot of CPU. It looks like, as long as I give it enough RAM to keep the folders in memory, the whole thing should be fast enough, which is great. Any other tips-n-tricks to keep the email server speedy and the users happy? Should I worry about mbox_very_dirty_syncs as long as there are no other MUAs? -- Florin Andrei http://florin.myip.org/

[Dovecot] File Permissions and delivery
by Simon Brereton 26 Aug '11

26 Aug '11

Hi I'm very new to Dovecot (been using Courier for 5 years), but I've been persuaded of the merits of Dovecot and since the server needs upgrading that seems like the perfect time/excuse. On a test server, I set up postfix and installed Dovecot (running 32-bit Debian Squeeze, installed from apt-get). I mirrored the mail store (Maildirs, for historical reasons located under /var/spool/mail/virtual/domain.com/user). Then I ran the courier migration perl script and everything was fine and dandy. However, when I can to do the production migration, things weren't as smooth. The new server is 64-bit (not that I think it makes a difference, but if you're going to help me you should have all the information :) Again, I installed Postfix and Dovecot Took down the old server Mirrored the Maildirs Ran the migration script Restarted everything At this point everything looked like it was ok. Mail was being received and delivered to the Maildirs and the IMAP login was fine. However, I noticed errors in the logs when retreiving mail with the MUA along the lines of: Aug 26 16:59:48 mail dovecot: IMAP(simon(a)lydiard.net): open(/var/spool/mail/virtual/domain.net/simon/cur/1314328966.V801I166601bM7… failed: Permission denied (euid=999(mailsystem) egid=115(mailsystem) missing +r perm: /var/spool/mail/virtual/domain.net/simon/cur/1314328966.V801I166601bM756462.mail.net,S=2461:2,) After messing around with the chown and chmod (even though these were exactly the same as the test server) I finally discovered the issue. mail:~# ls /var/spool/mail/virtual/domain.net/simon/new/ -rwxrwx--- 1 postfix mailsystem 2.5K Aug 26 03:33 1314326000.V801I1666018M803015.mail.net,S=2461:2, -rwxrwx--- 1 postfix mailsystem 2.5K Aug 26 03:36 1314326209.V801I1666019M447273.mail.net,S=2460:2, -rw-rw---- 1 postfix mailsystem 2.5K Aug 26 04:00 1314327630.V801I166601aM308173.mail.net,S=2477:2, -rw------- 1 postfix mailsystem 2.5K Aug 26 04:22 1314328966.V801I166601bM756462.mail.net,S=2461:2, -rw------- 1 postfix mailsystem 1.1K Aug 26 16:28 1314372534.V801I166601cM615258.mail.net,S=1097:2, -rw------- 1 postfix mailsystem 1.1K Aug 26 16:31 1314372685.V801I166601dM264242.mail.net,S=1097:2, Mails are being delivered with 0600 permissions and not 0660 (the mails from courier seem to have all been 0770 as you can see). If I manually change the permission (to 0660) then I can see the mail in the MUA. After thinking for a while it occurred to me that this is covered in the LDA section. But making changes to the config file (either permissions or UID/GID) doesn't seem to make a difference. (Yes, I did restart postfix and dovecot after the changes). Anyway, here is my dovecot -n: mail:~# dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.2 ext3 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_ca_file: /etc/ssl/keys/ca.crt ssl_cert_file: /etc/ssl/keys/mail.net.crt ssl_key_file: /etc/ssl/private/mail.net.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mailsystem mail_location: maildir:/var/spool/mail/virtual/%d/%n maildir_very_dirty_syncs: yes mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 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 lda: postmaster_address: postmaster@net mail_plugins: quota log_path: info_log_path: deliver_log_format: msgid=%m: %f: %$ auth default: mechanisms: plain login user: mailsystem verbose: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch userdb: driver: static args: uid=999 gid=115 home=/var/spool/mail/virtual/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: mailsystem master: path: /var/run/dovecot/auth-master mode: 432 user: mailsystem group: mailsystem plugin: quota: maildir As you can see, I tried to go 0660 in both client and master.

I'm pretty sure it's an error on my part. I'm just not clued up enough to know where. My second problem is that I thought I had things back to where they were before I messed with chown and chmod, but now I get this in the logs dovecot: dovecot: Fatal: chdir(/var/spool/mail/virtual/domain.net/simon//) failed: Permission denied (euid=999(mailsystem) egid=115(mailsystem) missing +x perm: /var/spool/mail/virtual) But the ls on that is exactly the same as on the test server: ls /var/spool/mail/virtual/ total 44K drwxrwS--- 11 postfix mailsystem 4.0K Aug 25 23:07 ./ drwxrwsr-x 5 amavis mailsystem 4.0K Oct 19 2009 ../ drwxrws--- 5 mailsystem mailsystem 4.0K Aug 26 02:33 domain.net/ So, now I'm stumped.

Hi, I saw that thread already, however it does not offer any solution that can be applied to dovecot directly. That thread has also been asleep for well over a year. It couldnt be that hard for the author to implement this function.

I saw a few commits for 2.0.13 that added MAIL_FETCH_POP3_ORDER, but I haven't been able to find any information on how to use it. I'm migrating from a Merak mail server into dovecot and all the email can be copied directly into a Maildir/cur directory. The filenames are just the timestamps. When I check with dovecot pop3, they seem to be randomly ordered. I'm hoping this provides a solution where it will look at the file list or stat order. If this isn't possible, can someone tell me how I can change the order in which dovecot lists mails in a UIDL in POP3? Thanks, Nick Celebic

[Dovecot] Catch22: user needs space to fix out of space condition
by Joseph Tam 25 Aug '11

25 Aug '11

A mail user reported that he filled up his INBOX (despite reminders he was approaching his filesystem quota), and furthermore, he could not fix the situation because he couldn't expunge message he marked for deletion. The dovecot logs revealed the cause dovecot: imap(user): Error: open(/var/mail/user.lock) failed: Disc quota exceeded This created an impasse where a user cannot free space because he needs to create a lock file that cannot be created because he needs free space. Is there any way out of this without administrator intervention? Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] dovecot and maillists problem
by Костырев Александр Алексеевич 25 Aug '11

25 Aug '11

Hello there! I have a little trouble with using dovecot as lmtp and maillists. I use dovecot 2.0.13 with exim 4.72 on Debian 6.0. (All stuff at one host). info of maillists is store in mysql table, for example: +---------+-------------------------------------------------------------------------------------------------+ | name | recipients | +---------+-------------------------------------------------------------------------------------------------+ | Hab_Tax | 2504000067-253601001.253809737993@25.example.org,2721097514-272101001.271300057673@.example.org | +---------+-------------------------------------------------------------------------------------------------+ The problem is: When I send a letter to short maillist (as above) it get the same ID and stored only once in the maildir of one user who is the member of that maillist - that's ok, but When I send a letter to maillist with a large number of recipients it occurred that it's saved more than one, because of the headers added by dovecot lmtp (I've changed host name): diff letter_in_one_user/1314238006.M841940P6916.pink\,S\=12778136\,W\=12953189 letler_in_second_user/new/1314237993.M460165P6916.pink\,S\=12778136\,W\=12953189 3,4c3,4 < by pink.atlas-2.ru (Dovecot) with LMTP id 6UiGJBWuVU4EGwAA1nFjLA < ; Thu, 25 Aug 2011 13:06:46 +1100 --- > by pink.atlas-2.ru (Dovecot) with LMTP id VUeGJBWuVU4EGwAA1nFjLA > ; Thu, 25 Aug 2011 13:06:29 +1100 It's the same letter accept the date and id.

[Dovecot] On IMAP vhost login, only Username being used

Attempting IMAP SSL login on new installation, using Icedove (Debain Thunderbird variant), login fails.

[Dovecot] Post-login scripting with virtual users
by Mark Willcox 25 Aug '11

25 Aug '11

I am running Dovecot 2.0.13 on Fedora 15. I have migrated from a bincimap installation using checklocalpwd. All email is in folders owned by a unprivileged user, popuser. The email users are entirely virtual and have no relationship to actual linux users. My userdb calls return the UID and GID of popuser and all goes well retrieving the mail via POP3 and IMAP. I am trying to implement a Post-login script to register the IP address that the authentication came from. Dovecot seems to be trying to execute the script as the email non-user, which does not work. I have specified that the script should be run as popuser, but it still runs as devnull(a)dhzone.com for instance. Everything up top that point seems to be happening happily under popuser. I added a "user = popuser" directive and it had no effect that I could see. I know that dovecot read the directive because I changed it to "user = 555" and dovecot would not run because "555" is not a user. I tried adding a "User = popuser" within the unix_listener but that also had no effect. Any ideas? Thank you! ------------------------------ Here is my dovecot -n: # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.40.3-0.fc15.x86_64 x86_64 Fedora release 15 (Lovelock) auth_debug = yes disable_plaintext_auth = no mail_debug = yes mbox_write_locks = fcntl passdb { args = /etc/dovecot/conf.d/dovecot-sql.conf.ext driver = sql } protocols = imap pop3 service imap-postpop { executable = script-login /usr/local/bin/set_postpop unix_listener imap-postpop { } user = popuser } service imap { executable = imap imap-postpop } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/conf.d/dovecot-sql.conf.ext driver = sql } ----------------------------------------------------- The dovecot-sql.conf.ext looks like this: driver = mysql connect = host=localhost dbname=webmail user=xxxx password=xxxx password_query = SELECT id AS user, IF( clear IS NULL, CONCAT('{CRYPT}',crypto), CONCAT('{PLAIN}',clear)) AS password \ FROM users WHERE id = '%u' user_query = SELECT home, uid, gid \ FROM users WHERE id = '%u' ------------------------------- >From the maillog: Aug 24 13:01:57 callisto dovecot: auth: Debug: client out: OK#0111#011user=devnull(a)dhzone.com Aug 24 13:01:57 callisto dovecot: auth: Debug: master in: REQUEST...

[Dovecot] Dovecot rejecting Vpopmail User 89
by hobie＠rumormillnews.com 24 Aug '11

24 Aug '11

I'm working to get Dovecot 2.0.13 working along with qmail, Vpopmail and Squirrelmail on a Debian 6.0.2 system, Dovecot compiled, not from a package. Vpopmail has a widely known assigned user/group ID of 89 and is the owner of all the mail folders. Regardless of value of first_valid_uid (1, 89, other), Dovecot denies Squirrelmail connection, saying it can't allow access to UID 89. "Couldn't drop privileges", it says. I'd be grateful for fixes, suggestions, or a pointer to an existing answer to this problem. Thanks ahead. :) Presently dovecot -n shows: # 2.0.13: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.2 ext3 auth_debug = yes disable_plaintext_auth = no mail_debug = yes mail_location = maildir:/home/vpopmail/domains/%d/%n/Maildir maildir_very_dirty_syncs = yes passdb { driver = vpopmail } protocols = imap pop3 ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } userdb { args = quota_template=quota_rule=*:backend=%q driver = vpopmail } --hobie

Enable auth_verbose and check the logs. But I'm pretty sure that means Dovecot can't change to the Maildir folder. I assume the user's folder is owned by vpopmail:vchkpw? Is the Maildir NFS mounted or local? Rick Quoting hobie(a)rumormillnews.com: > Thanks, Rick. :) Changed first/last uid/gid so all show 89 and restarted > Dovecot, no change.

[Dovecot] BUG - lmtp multiple recipients fail - setuid issue?
by Boris Lordis 24 Aug '11

24 Aug '11

Hello, I am not having much luck on this particular issue so I wanted to make sure that this is registered as a potential bug. The essence of the problem is that for a given message addressed to multiple users, lmtp writes the message correctly to the first addressed user only, then subsequent user writes fail as the lmtp process doesn't run with the proper permissions and tries to link files from different users as part of its message writing. Below you can see that lmtp (running with steve's id, who was the first listed recipient) is trying to link a file in jerry's inbox meeting with failure: Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): Error: link(/spool/mail/j/jerry/mail/INBOX/u.20423, /spool/mail/s/steve/mail/INBOX/.temp.1311791081.P12412Q2M989550.testmailserver.) failed: Permission denied Jul 27 11:24:42 testmailserver dovecot: lmtp(12412, steve): +1IXBeVXME58MAAARoVNxQ: msgid <201107271824.p6RIOPa5020900 at backup.>: save failed to INBOX: Internal error occurred.

[Dovecot] Attachments not removed from single store
by Karsten Becker 24 Aug '11

24 Aug '11

Hi. Well, I've the next problem. I turned on the new attachment de-duplication stuff in the configuration. If I send an attchment between two accounts on my test system, the attment gets saved ion the configured mail_attachment_dir. But... if I delete it from the senders Send folder and the receivers Inbox (and of course empty Trash afterwards in both cases), the hashes and the attachment are not deleted in mail_attachment_dir (as I would expect). Is this a bug, or have I misunderstood the concept of storing attachments?

[Dovecot] Cannot delete subfolder in public folder
by Karsten Becker 24 Aug '11

24 Aug '11

Hi there, I have the problem that I'm unable to delete a subfolder (again) I created within a public folder. I've already read about configuring Thunderbird to delete immediately - which I did. But it still doesn't work. I delete -> the folder is gone -> I get a TB error message saying "The folder doesn't exist" -> after restarting TB the folders appear again. Maybe someone has a hint. My tip is that I may have a wrong understanding of the ACL mechanism... :-( Regards from Berlin/Germany Karsten ------------------------ Log: > Aug 24 00:01:37 mail01 dovecot: imap(karsten.becker(a)company.eu): Debug: acl vfile: file /etc/dovecot/global-acls//.DEFAULT not found > Aug 24 00:01:37 mail01 dovecot: imap(karsten.becker(a)company.eu): Debug: acl vfile: file /srv/vmail/user-mailboxes/company.eu/karsten.becker/mailboxes/dovecot-acl not found > Aug 24 00:01:37 mail01 dovecot: imap(karsten.becker(a)company.eu): Debug: acl vfile: file /etc/dovecot/global-acls/Folders/test01/aaa not found > Aug 24 00:01:37 mail01 dovecot: imap(karsten.becker(a)company.eu): Debug: acl vfile: reading file /srv/vmail/public_folders/test01/aaa/dovecot-acl Here's the filesystem structure in /srv/vmail: > root@mail01.compdmz.local:/srv/vmail# ls -l public_folders/test01/ > total 20 > drwxr-xr-x 5 vmail vmail 4096 2011-08-23 23:50 aaa > drwxr-xr-x 2 vmail vmail 4096 2011-08-23 21:45 cur > -rw-r--r-- 1 vmail vmail 25 2011-08-23 22:19 dovecot-acl > drwxr-xr-x 2 vmail vmail 4096 2011-08-23 21:45 new > drwxr-xr-x 2 vmail vmail 4096 2011-08-23 21:45 tmp > root@mail01.compdmz.local:/srv/vmail# Here's the content of dovecot-acl (there are another ones in subfolder aaa with the same content, inherited during creation): > authenticated lrwstipekx Here's my configuration of Dovecot: > # 2.0.13: /usr/local/dovecot-2.0.13/etc/dovecot/dovecot.conf > # OS: Linux 2.6.32-33-server x86_64 Ubuntu 10.04.3 LTS ext4 > doveconf: Warning: Dovecot was last started using /etc/dovecot/dovecot.conf, but this config is /usr/local/dovecot-2.0.13/etc/dovecot/dovecot.conf > auth_cache_negative_ttl = 0 > auth_cache_size = 10 M > auth_mechanisms = plain login > base_dir = /usr/local/dovecot/var/run/dovecot > dict { > acl = mysql:/etc/dovecot/dovecot-dict-shared-mailboxes-mysql.conf > expire = mysql:/etc/dovecot/dovecot-dict-expire-mysql.conf > quota = mysql:/etc/dovecot/dovecot-dict-quota-mysql.conf > } > log_timestamp = "%Y-%m-%d %H:%M:%S " > login_greeting = Company Institute > mail_attachment_dir = /srv/vmail/attachments > mail_attachment_hash = %{sha256} > mail_cache_min_mail_count = 2 > mail_debug = yes > mail_location = mdbox:/srv/vmail/user-mailboxes/%d/%n > mail_plugins = acl expire quota > mailbox_idle_check_interval = 1 mins > namespace { > inbox = yes > location = > prefix = > separator = / > subscriptions = yes > type = private > } > namespace { > list = children > location = mdbox:/srv/vmail/user-mailboxes/%%d/%%n > prefix = Users/%%d/%%n/ > separator = / > subscriptions = no > type = shared > } > namespace { > list = children > location = maildir:/srv/vmail/public_folders:INDEX=/srv/vmail/user-mailboxes/%d/%n/public_folders-seen:LAYOUT=fs > prefix = Folders/ > separator = / > subscriptions = no > type = public > } > passdb { > args = /etc/dovecot/dovecot-mysql.conf > driver = sql > } > plugin { > acl = vfile:/etc/dovecot/global-acls:cache_secs=300 > acl_shared_dict = proxy::acl > expire = Trash > expire2 = Trash/* > expire3 = Junk > expire4 = Junk/* > expire_dict = proxy::expire > quota = dict:User quota::proxy::quota > quota_rule = *:storage=10485760 > quota_rule2 = Trash:storage=+1048576 > quota_warning = storage=95%% quota-warning 95 %u > quota_warning2 = storage=80%% quota-warning 80 %u > } > postmaster_address = postmaster(a)company.eu > protocols = imap pop3 > service auth { > unix_listener /var/spool/postfix/private/auth_dovecot { > group = postfix > mode = 0660 > user = postfix > } > unix_listener auth-master { > mode = 0600 > user = vmail > } > user = root > } > service dict { > unix_listener dict { > mode = 0600 > user = vmail > } > } > service imap-login { > inet_listener imaps { > port = 993 > ssl = yes > } > process_min_avail = 2 > } > service imap { > vsz_limit = 512 M > } > service pop3-login { > inet_listener pop3s { > port = 995 > ssl = yes > } > } > service quota-warning { > executable = script /usr/local/bin/quota-warning.sh > user = vmail > } > ssl = required > ssl_cert = </etc/postfix/ssl/mail01.compdmz.local.crt > ssl_key = </etc/postfix/ssl/mail01.compdmz.local.key > userdb { > args = /etc/dovecot/dovecot-mysql.conf > driver = sql > } > verbose_proctitle = yes > protocol lda { > auth_socket_path = auth-master > postmaster_address = postmaster(a)company.eu > } > protocol imap { > imap_client_workarounds = delay-newmail > imap_max_line_length = 128 k > mail_plugins = acl expire quota imap_acl imap_quota > } > protocol pop3 { > pop3_client_workarounds = outlook-no-nuls oe-ns-eoh > }

[Dovecot] acl with hierarchy separators mismatched config
by YAEGASHI Takeshi 24 Aug '11

24 Aug '11

Hi there, I'm testing dovecot 2.0.13 on Debian squeeze (deb from http://xi.rename-it.nl/debian) with the following doveconf -n. -------- # 2.0.13 (1449a2e2c1f5): /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-openvz-amd64 i686 Debian 6.0.2 first_valid_uid = 8 mail_debug = yes mail_location = maildir:~/Maildir mail_plugins = listescape mail_log notify acl namespace { inbox = yes location = prefix = separator = / type = private } namespace { list = children location = maildir:/var/mail/public:INDEX=~/Maildir/public prefix = Public/ separator = / subscriptions = no type = public } passdb { driver = pam } plugin { acl = vfile } protocols = " imap" ssl = no userdb { args = uid=mail gid=mail home=/var/mail/private/%u driver = static } protocol imap { mail_plugins = listescape mail_log notify acl imap_acl } -------- My primary interest is acl and listescape enabled folders in the public namespace. I've chosen "/" as the hierarchy separator to support folder names with dots ("."). /var/mail/public is a maildir with the maildir++ layout where the separator is a dot ("."). So I set up intial acls and folders as follows: -------- # mkdir /var/mail/public # echo 'anyone lra' >/var/mail/public/dovecot-acl # maildirmake.dovecot /var/mail/public/.aaa # echo 'anyone lrwstipekxa' >/var/mail/public/.aaa/dovecot-acl # chown -R mail.mail /var/mail/public -------- But my attempt to create a mailbox under Public/aaa fails with "Permission denied". -------- # imtest -a yaegashi localhost S: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready.

[Dovecot] LDA and auth-userdb socket permissions
by a.smith＠ukgrid.net 24 Aug '11

24 Aug '11

Hi, just wanted to check this as the wiki seems to have contradictory information. With respect to running the LDA as multiple UIDs the wiki says: [QUOTE]If you're using more than one UID for users, you're going to have problems running dovecot-lda, as most MTAs won't let you run dovecot-lda as root[/QUOTE] But in the example for the config file the text reads: [QUOTE] service auth { unix_listener auth-userdb { mode = 0600 user = vmail # User running dovecot-lda #group = vmail # Or alternatively mode 0660 + dovecot-lda user in this group } } [/QUOTE] So it says you can stick the LDA user just in the (vmail or whatever) group and that is enough. So you aren't restricted to a single UID for access anymore... I tested this and the later did not work, that is if I put my LDA user in the group for the auth-userdb socket with permissions 0660 I got an error back from dovecot saying that the owner was incorrect. So, as it stands I guess the bit about setting group should be removed from the wiki? Secondly, why doesn't this currently work? Why is the owner all important? thanks Andy.

[Dovecot] dovecot and tcpwrappers
by Kees Lemmens 23 Aug '11

23 Aug '11

Hi, I used dovecot 1.x for quite a while and it worked fine. However, I used it through inetd and used hosts.allow/deny to restrict access to only certain groups of systems. Since yesterday I have dovecot 2.0.13. But in version 2.0.13 it seems that starting using inetd doesn't work anymore : I only get a strange error message if I try to connect using telnet : telnet localhost imap doveconf: Fatal: execvp(imap-login) failed: No such file or directory I tried a lot of things but couldn't get it going over inetd so I decided to start it directly using an init script, also because you say in the wiki this is (now) the preferred method. That indeed works fine, but I realised today that dovecot is now completely ignoring all my hosts.allow/deny settings and so is worldwide accessible ! Is dovecot indeed ignoring hosts.allow/deny ? And if so, how can I have the same amount of protection as I previously had with dovecot 1.x over inetd ? BTW: I tried to post on the mailinglist but it seems I can't access them it the moment, altough I did subscribe and login. Is there anything wrong ? Thanks for your reply ! -- With best regards, Kees Lemmens. ----------------------------------------------------------------------- Delft Institute of Applied Mathematics (DIAM), Faculty Electrical Engineering, Mathematics and Computer Science, Delft University of Technology, Delft, The Netherlands,

[Dovecot] zlib plugin doesn't read concatenated .gz mailbox
by Dmitry Nezhevenko 23 Aug '11

23 Aug '11

Hi, I've observed that dovecot doesn't displays all mails from compressed via gzip mailbox (mbox). At the same time "mutt -f mailbox.gz" displays it correctly with all messages. I'm using archivemail to archive old mails. Internally it creates new "gzip" archive with "expired" messages and then concatenates it with archive. The easiest way to reproduce it without archivemail is to create two mailboxes, gzip them independently and then concatenate to one gzip archive. mutt, gunzip and other tools understands such archives. Also I've shared such mbox: http://dion.org.ua/uploads/2011/07/dovecot_test_gzip.gz It should contains ~20 messages. dovecot will "see" only two first. PS. % sudo dovecot --version 2.0.13 -- WBR, Dmitry

[Dovecot] dovecot's documentation dearth
by Postmaster 23 Aug '11

23 Aug '11

Hello. The first thing for me to say is thanks! I've been using dovecot since test 61 and it has basically performed flawlessly for me from day number 1. Dovecot makes me look like a genius sysadmin, especially compared to my colleagues struggling with exchange. So thanks, gracias, obrigado!! I'm working on a configuration for 2.0 and I'm finding the documentation somewhat difficult. I think it would be very helpful to me to have encountered a single page that detailed all available configuration sections. I don't know how to find out what the sections are, when to use them or what specifically they control. So far I've encountered... passdb plugin service protocol userdb local_name (and I think there is another one of these for ips) The service section itself would benefit from a single page detailing all of the possible types of service sections available. The next problem I've had is discovering that several parts of dovecot have no documentation at all even though they are standalone executables run by root. config, log, and ssl_params all run as root but there is also anvil and they look to me like they could support listening on a port if inet_interfaces is defined. You can say, "Relax fella, trust me. These programs are all part of dovecot and are run only if they're needed." Then I'll say, "Yes but I'm the administrator. I need to know how the parts fit together to know if the system's broken." Then you say, "Well that makes sense, but the things you're talking about aren't really configured. They are mostly internal to dovecot, they just happen to be broken out into external programs. You may as well be asking for documentation on a specific function in a library. If that's what you want, you can read through the source code." Well I guess that would be one solution. The bottom line is that it gives me an uncomfortableness to not be able to control or explain the operation of the software I'm supposedly administering. Take the program named log (which should be named dovecot-log or something less generic), it is launched even though I've specified syslog in the configuration. Logging is not interrupted when the process is killed. So, why is it running? What is it doing? Why does it need root? How do I control it? I think these are all good questions for an administrator to ask. That's my feedback for what it's worth, but mostly, thanks again for dovecot!

[Dovecot] Default and per-User sieve script
by Patrick Westenberg 23 Aug '11

Hi guys, is there any way to configure Dovecot to process the default sieve script and, after that, a user specific script? I have a default script to sort spam into a spam folder but if a user specific script is present, the default script is ignored. sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_global_path = /usr/local/etc/dovecot/sieve/default.sieve Regards Patrick

[Dovecot] dovecot deadlock with procmail
by kunal verma 23 Aug '11

23 Aug '11

I m using dovecot 1.0.7. I m having problems in mail delivery to my mail server locally. When a user sends a mail few mails are in mail Q for longer period of time. The local delivery agent(*procmail*) is trying to deliver the mail at regular interval but it is unable to deliver. But as soon as I *restart* *dovecot* the mails in the Q are delivered immediately. I suspect it is because of locking of *mbox* file of users by dovecot. How to overcome this problem as mails are some mails are taking hours to be delivered?? please let me know the solution.

[Dovecot] Large Mailbox Slow
by Matt 23 Aug '11

23 Aug '11

Doubt if there is any answer to this but will ask anyway. Have a few pop3 accounts with thousands of messages. Its slow when checking email naturally. Are there any tweaks to speed it up? I imagine there is an exchange of the message and header list which is the slow down. Too bad the list could not be compressed with gzip or something first. I think http has an option similar to that. Just asking.

[Dovecot] Dovecot Postfix and ssl_require_client_cert
by mezzo 23 Aug '11

23 Aug '11

Hi, I have a working mail system with postfix 2.7 and dovecot 1.2.15. I use secure connections for imap and smtp. When I try to use client certificate authorisation I have some problems. As soon as I enable the dovecot feature ssl_require_client_cert I have to present a valid certificate to receive or send email. Receiving emails works fine, but I can not send emails any more. The only way I could get this to work was to disable smtpd_sasl_auth_enable so postfix did not tries to get authorisation from dovecot. This way I can not have sasl authorisation for localnet and client certificate authorisation from extern. The reson seams to be that postfix does not sent the valid-client-cert along with the other parameter that are needed to satisfy the auth-process of dovecot. I found a few threads from 2008 where this problem is discussed but without a final solution. Is there a way to enable ssl_require_client_cert in dovecot and have smtpd_sasl_auth_enable=yes in postfix? Better would be a way to tell dovecot only to use ssl_require_client_cert during the imap autorisation. I did not get it to work. I miss something?

[Dovecot] Update indexes with dovecot 1.1
by Angel L. Mateo 23 Aug '11

23 Aug '11

Hello, I have a farm of dovecot 1.1 servers (debian lenny). Mailboxes are in Maildir format. Is there any way to manually update indexes? Does it worth? I mean... Our problem is that mail is delivered via dovecot lda, but, because we have a farm of servers, we don't guarantee that mail is delivered through the same server that the user is using for his imap connection, so the imap server could have this index unupdated. So I want to force an update (or at least nearly updated) in order to have the index updated in all servers at the time the user get to work. -- Angel L.

[Dovecot] Disconnected: Too many invalid IMAP commands
by Steve Fatula 23 Aug '11

23 Aug '11

Using current Apple mail 4.5 as client to Dovecot 2.0.13 I see lots of these messages in the log file for one machine and account. Near as I can tell, the client still works (it's mine), but, the messages concern me. Is there some known issue with Apple mail, or, if not, how to capture the information needed to debug? Sample log entires for my user matching on the message: Aug 20 16:28:36 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=3242/14672 Aug 20 16:28:43 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=14219/231327 Aug 20 16:29:50 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=640/1968 Aug 20 16:29:57 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=3521/2024 Aug 20 16:30:04 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=6690/3415 Aug 20 16:30:05 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=5098/15294 Aug 20 16:30:06 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=706/15684 Steve

[Dovecot] Duplicate Email with Dovecot Sieve
by Holden Hao 22 Aug '11

22 Aug '11

I am trying to use Dovecot Sieve after upgrading Dovecot from 1.0.15 to 1.2.17. I used the same config file from the old version but I added some entries to make sieve work. In my initial tests, sieve works and is able to do the actions that I set it to do. However, I get 2 copies of incoming emails. The inbox would always preserve a copy even if the sieve filter is set to transfer emails to another folder or redirect it to another address. The logs do not seem to report any issues. I don't know what causes the problem and I would appreciate some pointers.

[Dovecot] Help With 'No SASL Authentication Mechanisms' Error

Hi, I'm trying to configure a new server with dovecot 2.0 and postfix 2.6.6. My previous servers have all been dovecot 1.x. Trying to port over my previous configurations has been a real headache.

[Dovecot] Dovecot 1.2.16 and Thunderbird 5 - pop3 mails not getting deleted
by Ian Evans 22 Aug '11

22 Aug '11

I run a Dovecot 1.2.16 pop3 server and have just started using the Thunderbird 5 email client. Thunderbird is set to leave the messages on the server unless they are over 91 days old. However, I'm not seeing it delete any of the older messages. I'll run a debug run of Thunderbird when I get back home, but I'm just wondering if there's any gotcha's I should be aware of with Thunderbird and Dovecot in a pop3 environment. The Thunderbird folks are wondering if it's the server not the client. Thanks.
