[Dovecot] Killing Dovect, an unpleasant surprise
by Stewart Dean 30 Jan '09

30 Jan '09

When it came time to upgrade DC or replace the certificate, I would find the root instance of dovecot and do a kill -7 of it. Within 20-30 seconds, all the hundreds of DC related processes would go away, I would swap the executable or certificate/key and restart DC. Very clean and quick. Surprise. After switching from 1.0.15 to 1.1.8 and doing the kill, I found that all the imap-login instances had been inherited by the root (1) process and did not go away. Yikes! An Unpleasant Surprise. So instead of being down for a minute, I was out for a much more noticeable 5-7 minutes, while I QUICK did an awk of the ps list to give me the pids and then xarg killed them. My boss asked me if this was a pink slip notice. :( Is this The Way Things Will Be? Is there a new way to kill everything DC related quickly and cleanly? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035 "Resolve then, that on this very ground, with small flags waving and tinny blasts on tiny trumpets, we shall meet the enemy, and not only may he be ours, he may be us." === From the introduction to the original Pogo Papers

[Dovecot] Trash for lda
by Alaa Ibrahim 30 Jan '09

Hi, I was wondering if there is a solution to the case when the user can't recieve emails because of being over quota, something like http://wiki.dovecot.org/Plugins/Trash, but for the lda, not the imap?

Hi Guys, I am just about to get my hands on a new blackberry mobile phone and I have done quite a bit of reading about different bits about getting the blackberry to work with Dovecot.

[Dovecot] deliver and qmail
by Tim Traver 29 Jan '09

29 Jan '09

Hi all, ok, after looking at all of the posts that I've found, and trying numerous settings, I am a little stumped as to how to set up the deliver program with qmail to get everything correct. Ultimately, I really don't want to do a lookup of the home dir if I don't have to. I'd rather specify the stuff in the .qmail-user file for that particular user to avoid the extra step. In looking in the wiki, it says for users without a lookup to use HOME=/path/to/user/homedir deliver -f $FROM_ENVELOPE but I can't do that in the .qmail file, which would normally look something like this : |/var/qmail/bin/preline -f /usr/local/libexec/dovecot/deliver -f ${SENDER:-<>} I would rather not do the master authentication socket as described for obvious reasons. is there a format in the .qmail file that I can use with deliver to achieve what I want??? Thanks, Tim.

[Dovecot] Confused about permissions needed for shared mailbox
by Thomas Hummel 28 Jan '09

28 Jan '09

Hello, let me re-state, hopefully in clearer terms, what I tried to described in a previous thread : With dovecot-1.1.8/Maildir/LDAP pass/userdb (prefetch), I'm trying to set up a Maildir ".box" shared in rw between 2 users in a "Public" namespace. I can't get it to work unless I chmod 777 everything, which obiously is not what I want. 1) am I correct thinking that the system_user userdb extra_field and unix permissions should be enough to achieve that and that ACLs is only if I want to fine tunes mailbox permissions ? 2) let's say that my public namespace prefix is Public/, that the .box/ maildir is in /path/to/public/.box and my 2 users belong to the doveshared unix group. I thought it would be enough to have drwxrws--- 3 root doveshared 4096 Jan 28 14:55 public drwxrws--- 3 root doveshared 4096 Jan 28 14:55 public/.box -rwxrws--- 1 root doveshared 0 Jan 26 18:25 public/.box/dovecot-shared provided that my prefetch userdb returns system_user, as I think the following says in dovecot-ldap.conf : pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,,,uidNumber=userdb_uid,gidNumber=userdb_gid,shadowMax=userdb_system_user and providedt that in LDAP shadowMax: 80 (whatever value). But this doesn't seem to work. By the way : Am I supposed to have a dovecot-shared file in public as well (that is not only in public/.box) ? 3) let's say I try ACLs with the same setup (anyone <all permissions> for starters) would pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,,,uidNumber=userdb_uid,gidNumber=userdb_gid,shadowMax=userdb_system_user.title=userdb_acl_groups and title: group1,doveshared be a correct setup ? Do I need an dovecot-acl file only in .box or in public too ? My understanding is that my setup doesn't work because for some reason, dovecot doesn't see my users secondary groups or doesnt take them into account... Any thoughts which might help ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Symlink shared mailboxes and system_user extra field
by Thomas Hummel 28 Jan '09

28 Jan '09

Hello, I'm trying to set up, as explained in the wiki, shared mailboxes with symlink. I'm running dovecot-1.1.8 with LDAP pass/userdb. The Maildir layout goes like this : /courriel/boites/foobar : Maildir of user foobar (nfs) /courriel/meta/foobar : control files of user foobar (nfs) /var/dovecot/indexes : indexes (locally stored) I created : /courriel/boites/doveshared/.box/ : the Maildir I want to share /courriel/boites/foobar/.box -> /courriel/boites/doveshared/.box (symlink) /courriel/boites/foobaz/.box -> /courriel/boites/doveshared/.box (symlink) the unix and LDAP group doveshared, so /etc/group holds : doveshared:*:<gid>:foobar,foobaz the permissions on the real Maildir are ok for that group : drwxrwx--- 3 root doveshared 4096 Jan 26 18:58 /courriel/boites/doveshared drwxrwx--- 5 root doveshared 4096 Jan 26 18:58 .box (in /courriel/boites) I made the userdb (prefetch) return the system_user extra_field (for now, I'm using an used LDAP attribute - I will create a new attribute in my schema later) : pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,,,uidNumber=userdb_uid,gidNumber=userdb_gid,shadowMax=userdb_system_user and it seems to be actually returned : Jan 27 09:34:10 munster3 dovecot: auth(default): ldap(foobar,157.99.64.42): result: uid(user)=foobar uidNumber(userdb_uid)=xxx gidNumber(userdb_gid)=xxx homeDirectory(userdb_home)=/home1/xxx/foobar userPassword(password)=<hidden> shadowMax(userdb_system_user)=380 But I can't subscribe to the mailbox : stat(/courriel/boites/doveshared/.box/tmp) failed: Permission denied (euid=xxx egid=<primary gid>) as a matter of fact, the egid seems to be the primary gid. What am I missing ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] (imap) killed with signal 9 on Linux/OpenVZ VPS
by Adam Flott 28 Jan '09

28 Jan '09

I'm trying to get dovecot running on my VPS and the main imap process is receiving a SIGKILL from what I presume to be the Linux Kernel and/or OpenVZ. This happens after I login and my client(s) just sit their idling. The mailbox is empty. I'm not running out of memory. stracing the process doesn't show anything interesting... ... gettimeofday({1233024777, 844804}, {420, 0}) = 0 gettimeofday({1233024777, 844912}, NULL) = 0 poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=2, events=POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 3, 10000) = -1 EINTR (Interrupted system call) +++ killed by SIGKILL +++ This is on a CentOS 5.2 VPS. I haven't changed much other than installing a few packages. I've also had this exact same problem on Debian 4.0 VPS (OpenVZ) under the same machine. Turning off SSL and logging in plain old IMAP didn't change anything. Under the Debian installation I tried the latest version of dovecot (1.1.8 or so), different I/O loop methods, turning them off, on, etc. The only other reference via Google I can find to this sort of problem is: http://www.dovecot.org/list/dovecot/2007-December/027440.html But that was with the login process, whereas mine is with the imap daemon.

[Dovecot] Old Thunderbird problem - need a fix
by Marc Perkel 28 Jan '09

28 Jan '09

I've been having a Dovecot/Thunderbird problem for about a year now and I need a fix. When I restart dovecot everything is fine but as the day progresses thing start deteriorating. When I empty my trash folder it doesn't empty. I get an indication that email has arrived in my inbox by the unread message count but can't access it. Messages arrive by appear to be empty. Folders that should be empty still have message counts showing. With all of the above problems - restarting dovecot make them all go away. I am doing something unusual in that I use Exim to directly deliver (maildir) to the inbox and other folders. And I have processes that take email out of certain folders (spam learning). Whatever the problem is I think that when I restart Dovecot I'm forcing Thunderbird to reconnect. Perhaps the solution is to somehow force Thunderbird to have to reconnect every time rather than have a persistent connection? Looking for suggestions. Thanks in advance.

[Dovecot] Store sent email
by pierre.casenove＠almerys.com 28 Jan '09

28 Jan '09

Hello all, I've set up a webmail solution based on RedHat EL 5, sendmail, spamassassin, clamAV and dovecot by following this tutorial: http://www.redhat.com/magazine/025nov06/features/email/index.html I have configured everything without any problem, I can send and receive emails, using Maildir store format. Now, what I don't know how to set up: I would like to store the emails sent by the users in a dedicated store (Like Sent Emails in many webmails).... and I've got no idea on how to do this! By googling a little, I found this thread ( http://www.dovecot.org/list/dovecot/2007-April/021447.html) where a plugin is mentionned. Has it been developped or is there another solution? I'm using dovecot 1.0.7, shipped with RHEL 5 distribution. I am really discovering all the products around the email so I'm a bit confused. Thanks a lot for your answer, Pierre

I'm using dovecot 1.1.6 over NFS. Any thoughts? Thanks in advance, gpg

[Dovecot] No Spaces in Directory names
by Matt Rude 27 Jan '09

27 Jan '09

How can I make it so my users can not create folders with spaces in them? Or allow them to create such folders but rewrite them on the hardrive with a "_" or some other symbol. I have looked threw the wiki but couldn't find anything about folder name restrictions or folder name rewriting (rewrite the space to a "_"). Im having problems with some of the expire and compress scripts when it hits these types of folders. Is dovecot able to restrict or rewrite the names of imap folders? dovecot -n # 1.1.9: /usr/local/etc/dovecot.conf # OS: Linux 2.6.27.9-159.fc10.i686 i686 Fedora release 10 (Cambridge) ext3 listen: *:143 ssl_listen: *:993 ssl_cert_file: /etc/postfix/SSL/mail.mattrude.com.cert ssl_key_file: /etc/postfix/SSL/mail.mattrude.com.key login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_user: postfix mail_location: maildir:/var/spool/virtualmailboxes/%d/%u/imap/:INBOX=/var/spool/virtualmailboxes/%d/%u/ mail_plugins: quota imap_quota zlib auth default: mechanisms: plain login cram-md5 cache_size: 128 cache_ttl: 600 master_user_separator: * passdb: driver: sql args: /etc/dovecot-mysql.conf passdb: driver: sql args: /etc/dovecot-sql-master.conf pass: yes master: yes userdb: driver: sql args: /etc/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: virtualmail group: virtualmail plugin: sieve: /var/spool/virtualmailboxes/%d/%u/dovecot.sieve sieve_storage: = /var/spool/virtualmailboxes/%d/%u/ quota: maildir quota_rule: *:storage=10M quota_rule2: Trash:storage=20% Thanks -Matt

[Dovecot] Dovecot discards mail over quota
by Gary V 27 Jan '09

27 Jan '09

I'm new to Dovecot, using 1.1.8 and I just wanted to verify that what I am observing is the intended behavior. I'm using Maildir++ quota. When a message is delivered to a mailbox that cannot accept the message because it would place them over the quota limit, deliver states to the MTA that the messsage was delivered successfully (example using postfix): Jan 17 12:05:31 msa postfix/pipe[13983]: 088C5B9D47: to=<test(a)example.com>, relay=dovecot, delay=0.72, delays=0.34/0.02/0/0.36, dsn=2.0.0, status=sent (delivered via dovecot service) But in actuality the mail is discarded (dropped). Then a bounce is created stating the mail was rejected: Your message to <test(a)example.com> was automatically rejected: Quota exceeded (mailbox for user is full). Question: is it possible (without changing code) to alter this to where deliver would instead tempfail or something. Somehow it seems wrong to me to tell the MTA that everything is good, and then silently discard messages - regardless of the fact dovecot creates a bounce. This is not necessarily ideal either, but I _am_ wondering if this is configurable or not. deliver(test(a)example.com): 2009-01-17 12:05:31 Info: msgid=<1293474859.20090117120812(a)example.com>: save failed to INBOX: Quota exceeded (mailbox for user is full) deliver(test(a)example.com): 2009-01-17 12:05:31 Info: sieve runtime error: Keep: Generic Error deliver(test(a)example.com): 2009-01-17 12:05:31 Error: sieve_execute_bytecode(/var/sieve/global.sievec) failed deliver(test(a)example.com): 2009-01-17 12:05:31 Info: msgid=<1293474859.20090117120812(a)example.com>: rejected: Quota exceeded (mailbox for user is full) deliver(garyv(a)example.com): 2009-01-17 12:05:31 Info: msgid=<dovecot-1232219131-401523-0@msa>: saved mail to INBOX -- Gary V

[Dovecot] behavior of dovecot with Openldap
by Masaharu Kawada 27 Jan '09

27 Jan '09

Dear team, I'm sorry if this is a stupid question, but I'd like to know the behavior of dovecot in a particular stuation. My questions are as follows. In /etc/dovecot-ldap.conf, 'hosts=' field is the one which can be used to specify availabled ldap server to access from the clients to authorize. And also sevral ldap servers can be specified in 'hosts =' field as shown like below. hosts = ldap-server1.example.com ldap-server2.example.com ※both server have the same configuration and available to replication ldap-server1(master) to ldap-server2(slave). If this is right, how does dovecot know which ldap server is currently used? and if the master dies, how does dovecot know and switch to slave one? In addition, which one is the exact behavior of dovecot in case master server dies? 1. only swithcing to the slave server 2. switching to the slave server, and once the master server is reactive then switch back to the master server automatically OS：RHEL4 U3 kernel 2.6.9-34.ELsmp openldap-2.2.13-12.el4 Thanks in advance, Masaharu Kawada ------------------- Masaharu Kawada Associate Global Support Engineer Red Hat K K Ebisu Neonato 8F 1-18 Ebisu 4-chome, Shibuya-ku Tokyo 150-0013, Japan Direct: +81-3-5798-8482

[Dovecot] FOLDER INTERNAL DATA (uw pine header)
by Charles Gregory 26 Jan '09

26 Jan '09

Hello! I run Dovecot on CentOS 4 (dovecot-1.1.4-0_81.el4), and I *also* run the "Alpine" mail system that comes with that OS. Alpine still writes out the 'FOLDER INTERNAL DATA' pseudo-message at the beginning of each user's mbox, but dovecot does not. I make use of that record as a simle/quick way to verify when a user actually last read their e-mail (for administrative purposes, identifying stale/unused accounts), so is there any way to configure/command dovecot to write (or update) these hidden messages? (Note: I tried looking in the archives, but most references seemed to be about this message being a 'side effect' of transferring *from* UW IMAP, and how to get 'rid' of it. Not what I need. :) Apologies if this was covered before in a different thread.) - Charles

[Dovecot] uint_cmp bug
by Mike Abbott 26 Jan '09

26 Jan '09

In reviewing the differences between 1.1.8 and 1.1.9 I saw a probable bug in the new function uint_cmp() in src/lib-storage/index/maildir/ maildir-sync-index.c: if (*i1 < *i2) return -1; else if (*i1 > *i2) return -1; else return 0; The second case should return 1 not -1.

[Dovecot] Released ManageSieve v0.10.5 for Dovecot v1.1.9
by Stephan Bosch 26 Jan '09

26 Jan '09

Hello Dovecot users, Because there was a crash bug in the ManageSieve v0.10.4 login daemon, I made a new release of the ManageSieve service for Dovecot v1.1. This release includes two other small fixes as well. Changelog v0.10.5: - Fixed a segfault bug in the authentication time-out. Bug report and trace provided by Wolfgang Friebel. - Fixed maximum permissions for uploaded scripts; was 0777. This was shielded however by the default umask (not documented to be configurable), so the actual permissions would never have been 0777. - Fixed handling of ~/ in use of mail-data for script location The following files are released: ManageSieve package: http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.5.tar.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.5.tar.gz.s… ManageSieve patch: http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.9-managesieve-0.10.5.diff.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.9-managesieve-0.10.5.diff.g… Have fun testing the new releases and don't hesitate to notify me when there are problems.
