[Dovecot] Multiple LDAP Userdb lookups
by David 29 Oct '09

29 Oct '09

Hello one & all, I understand it is possible to do multiple lookups for userdb info of different types, for instance a local "real" account & virtual MySql lookups. Is it possible to do two separate ldap lookups to differnt parts of the same AD domain? I have a config file to do my authentication lookup against the domain. Then I have a 2nd config file for the userdb lookups which uses ldap to query our AD for their userdb info. I need to query a 2nd part of the AD for another group of users & unfortunately putting all users into one container isn't possible. So, if I add another ldap stanza to dovecot.conf will I break anything? Cheers, David. This email is confidential and is intended solely for the use of the parties to whom it is addressed.

[Dovecot] Thunderbird and Trash folder
by Stefan Onken 29 Oct '09

29 Oct '09

Hello, I have my problems with the Trash folder in thunderbird. Most of the times (it did work, but only for a short period) Thunderbird is not considering the "Trash" folder (or in my case the "Papierkorb") as the trash folder. The symbol disappears and I am not able to delete folders. Deleted emails are disappearing at all. The usual Google solutions like maildir vs. mbox doesn't help a lot, I am using maildir and the directory structure looks fine. I noticed that I have two trash folders, one with "INBOX.", one without. That may be a problem with Squirrelmail, because I am using both Thunderbird and Squirrelmail. Any idea to solve this issue with Thunderbird ? Thank you, Stonki Dovecot -a: http://www.pastebin.org/49066 Directory structure: http://www.pastebin.org/49067

[Dovecot] Multiple SSL certs question
by Jean-Baptiste Vignaud 29 Oct '09

29 Oct '09

Hello; I was reading the message "how to config dovecot for multiple domains, multiple SSL certs, and conditional IP access -- with passwd-file passdb?", and i was wondering if Dovecot could support the SNI extention of TLS ? SNI is Server Name Indication where during the TLS negotiation, the client set the name of the server it tries to reach I dont know if any imap/pop client support this yet, but this would be a great feature for one IP/multiple virtual domains. Each SNI client would have the correct certificate and not the "main/generic' one. It seems that mutt has a patch for that http://www.mail-archive.com/mutt-dev@mutt.org/msg05251.html

[Dovecot] Hundreds of auth-worker sockets in /etc/dovecot
by Eggert Ehmke 28 Oct '09

28 Oct '09

I run dovecot 1.2.6, before last update I had 1.2.2. on Debian Lenny. I noticed that my config directory /etc/dovecot is filled up with hundreds of old auth-worker.12345 sockets. I guess they should have been cleaned up, is there a misconfiguration? When I remember right, this did not happen with dovecot 1.1.

[Dovecot] listing available subscriptions - shared mailboxes
by Hendrik Pahl 28 Oct '09

28 Oct '09

hi everybody, got a strange issue with 1.2.4 on SLES11. When listing the user's available subscriptions with any client, every shared mailbox that can be subscribed is listed twice, once with it's correct name, 'folder' for example. the second appereance is without the last letter of the name, 'folde' for example. strange behaviour, since this happens with any client. i hope somebody know what is wrong here. thanks in advance, hendrik -- LWsystems GmbH & Co.

Hello all, I use dovecot11-1.1.7-1.4.1 with OpenSuse 11.1. Everything works fine, except the vacation with managesieve.

[Dovecot] Sieve vacation with russian subject
by Nikita Koshikov 28 Oct '09

28 Oct '09

Hello list, I have noticed that sieve vacation action breaks some non-english letters in the subject. I tested with russian language, if subject contains letters from specific diapason russian alphabet, the message received with unreadable subject, but text in the body with the same letters looks ok. Here is example of full subject header, it contains russian alphabet: Subject: абвгде�?жзийклмноп�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�? Maybe this headers will be usefull: MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit .dovecot.sieve file looks correct, here is it: require ["vacation"]; # rule:[test] if anyof (true) { vacation :days 1 :addresses ["user(a)domain.com"] :subject "абвгдеёжзийклмнопрстуфхцчшщъыьэюя" text: Тестовое русское сообщение(Test russian message). ; } I'm running dovecot-1.1.16 with dovecot-sieve-1.1.6 and managesieve-0.10.6. Please tell, is it possible to fix this ?

[Dovecot] antispam-plugin 1.2 and trailing carriage-returns
by Karsten Bräckelmann 28 Oct '09

28 Oct '09

Guys, Dovecot 1.0.15 [1], just built the latest antispam-plugin 1.2 (tarball) for testing, mailtrain backend for SA integration. Both built from custom spec files. The mail that is being trained is different than its respective source in the mbox file. The trained one shows added, trailing carriage-return chars for all headers, which are not in the headers in the mbox file. This breaks sa-learn -- both these variations are different, and SA would learn *both* when run against each one separately. How comes? Any insight? How could I fix this, other than wrapping the sa-learn inside another shell script and have sed strip off the noise? This becomes more of an issue, once I switch from sa-learn to the lightning-fast spamc training variant. TIA guenther [1] Yes, I know, sorry. Don't want to change everything at the same time, and the target system I'm experimenting for runs that version, too. -- char *t="\10pse\0r\0dtu\0.@ghno\x4e\xc8\x79\xf4\xab\x51\x8a\x10\xf4\xf4\xc4"; main(){ char h,m=h=*t++,*x=t+2*h,c,i,l=*x,s=0; for (i=0;i<l;i++){ i%8? c<<=1: (c=*++x); c&128 && (s+=h); if (!(h>>=1)||!t[s+h]){ putchar(t[s]);h=m;s=0; }}}

[Dovecot] Dovecot, Shared Mailboxes (via symlink), and ACLs
by Dave 28 Oct '09

28 Oct '09

Hello! I just joined the list and will be happy to help where I can in my limited experience, but also come to the table with a question. I think there's something I'm missing regarding shared mailboxes and ACLs, so I will describe my situation and see if I am understanding correctly (running Dovecot 1.1.10). I have read over the Dovecot Wiki many times and have scoured many forums but still can't seem to find a solution. I have an IMAP mailbox that is working fine (user imapuser), so the maildir and related structure is in: /home/imapuser/Maildir I have another IMAP mailbox for another imap user, newuser1, also working fine, with maildir and related structure in: /home/newuser1/Maildir I have created a symlink under newuser1's Maildir to imapuser's Maildir so as to give newuser1 access to the things in imapusers's inbox. I have also symlinked inside the newuser1 Maildir to a folder under imapusers's inbox, let's call it "MailingList", basically settiing up something like: /home/newuser1/Maildir: cur/ .imapuserinbox -> /home/imapuser/Maildir .imapusermailinglist -> /home/imapuser/Maildir/MailingList new/ tmp/ (... and various other Dovecot-related files, nothing ACL related.) Now, I have gotten the shared boxes to work IF I changed the permissions to be rwx for user and group on /home/imapuser/Maildir/*, but this makes procmail (and .procmailrc) unhappy and it starts sending things to mbox files (old system) instead of sending them on to the Maildir. So that doesn't seem to work. Which led me to ACLs. Now, I've tried (after enabling the two appropriate lines in dovecot.conf and restarting dovecot, etc) both per-directory ACL files and global ACLs, and while I can get some things to *change* as viewed by my mail client, I can't seem to create consistent behavior. I know that's fairly vague, but it's like I'll change something in the global ACL and folders are affected that I wouldn't anticipate, based on what I'm understanding of ACLs. So, in the example above, if I enable global ACLs, what names do I use to refer to those shared boxes I'm trying to access? Do I use the link name I made, .imapuserinbox or .imapusermailinglist (without leading periods), like /etc/dovecot/acls/imapuserinbox, or is it based off of the original dir name? Like do I need something like /etc/dovecot/acls/MailingList ? What about the "inbox" I'm sharing in /home/imapuser/Maildir, how do I reference that? Is there a way to do it without affecting or changing permissions of other IMAP users and inboxes on the same system? One thing I am receiving consistently in the error logs is: mail dovecot: IMAP(newuser1): stat(/home/newuser1/Maildir/.imapuserinbox/tmp) failed: Permission denied (euid=152(newuser1) egid=100(usergroup) UNIX perms seem ok, ACL problem?) So it seems if I get the ACL stuff right, I will be in business. Any ideas?? Thanks for any help anyone can give!! Dave

[Dovecot] 1.1 Quota Question
by Marty Anstey 28 Oct '09

28 Oct '09

Hi, I'm not sure if this question has been asked before but some googling hasn't turned up anything really relevant. We are currently running Dovecot 1.1.16 & Postfix; maildir++. When a message arrives for a mailbox which is over quota, it is bounced. Obviously, this isn't very desirable; the primary downside to this is that when junk mail hits a full mailbox it's bounced to that recipient of the message. On a busy mail system, that could potentially get us blacklisted pretty quickly. Ideally we would like to reject the messages inline. Is there an easy way to set this up? Thanks, Marty

[Dovecot] Error: userdb lookup
by kfx 28 Oct '09

28 Oct '09

Hi list, I am trying to get rid of the "Error: file_dotlock_create(~/.dovecot.lda-dupes) failed: No such file or directory" by adding home directories to my virtual users (ldap). I want this home dir' to be specified like this: /var/vmail/$USER/home/ and the sieve scripts to go to: /var/vmail/$USER/home/sieve/ So as suggested before in this list, I have replaced: user_attrs = mailMessageStore=mail,mailQuotaSize=quota_rule=*:bytes=%$ by user_attrs = mailMessageStore=mail,mailQuotaSize=quota_rule=*:bytes=%$, =home=/var/vmail/%u/home But then the userdb lookup fail and it tells me this in the log: deliver(user@mydomain): Error: userdb lookup: connect(/usr/local/var/run/dovecot/auth-master) failed: No such file or directory This is strange because: a. the socket is at /var/run/dovecot/auth-master b. it is working flawlessly with the original user_attrs value So I am thinking that this setting is totally ignored by dovecot at some point.

[Dovecot] dovecot.log file permissions and ownership
by Jerry 27 Oct '09

27 Oct '09

Using FreeBSD-7.2 and Dovecot v1.2.4 what user does dovecot use to write to its log file? I have the logfile located in the /var/log directory. I have Postfix configured to use 'virtual' users and use dovecot for delivery. While dove can write to the file when accessed for POP services, when accessed via Postfix, I get this error message: Oct 25 07:02:15 scorpio postfix/pipe[56956]: B01BD2287E: to=<user(a)domain.com>, relay=dovecot, delay=220, delays=220/0.01/0/0.04, dsn=4.3.0, status=deferred (temporary failure. Command output: Can't open log file /var/log/dovecot.log: Permission denied ) I have used the following ownership types for the file: 1) root:wheel 2) dovecot:dovecot 3) root:dovecot 4) dovecot:wheel The only thing that works all the time is to give the file full r/w (0666) permission. That seems extreme. -- Jerry gesbbb(a)yahoo.com |::::======= |::::======= |=========== |=========== | A nuclear war can ruin your whole day.

[Dovecot] SetUID check problem
by Thomas Berezansky 27 Oct '09

27 Oct '09

Running dovecot 1.2.4 on FreeBSD using Postfix. Everything works fine normally, but deliver is executable by world. This is not normally a problem, as I don't run deliver SetUID root. But for whatever reason, when deliver is called by something that IS SetUID root I get the following error: /usr/local/libexec/dovecot/deliver must not be both world-executable and setuid-root. This allows root exploits. See http://wiki.dovecot.org/LDA#multipleuids Deliver's permissions look like this: -r-xr-xr-x While the program calling deliver has permissions like this: -r-s--x--- If it isn't possible for deliver to differentiate between being called by setuid root programs and being setuid root itself I don't think it should be doing that particular security check. Alternatively, there should be an option to turn that particular check off, but what little I saw of the source code and found searching the documentation told me that there doesn't seem to be such an option already. I also couldn't find any mention that this is fixed by 1.2.5 or 1.2.6. Thomas Berezansky Merrimack Valley Library Consortium

[Dovecot] Test environment question
by Stewart Dean 27 Oct '09

27 Oct '09

I want to test out my first V1.2 Dovecot (upgraded from V1.1) instance. What I have in mind to do is to run it on another machine that has the Inbox dir and homedirs NFS import mounted from the production mailserver. I then have 5 people test it in this test environment.... A) Then I can deal with the index filesystem in one of two ways: 1) Make it local OR 2) NFS import it from the production DC server Comments as to which is best? I have used #1 before...which caused some temporary unhappiness with the switchover and switchback....during which time the index is badly wrong and DC auto-rebuilds it... B) Is there anything else I should do/not do? C) Any ugliness that will surface in this testing lashup but isn't important? -- ==== 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

Hi, I recently moved from courier-imap to dovecot, to be able to work with managesieve. I use version 1.2.5, on suse 10.3. I used the script to migrate the courier maildir to dovecot format. It seems to work fine except for one problem : I use a number of aliasses and with Thunderbird I can select which alias (e-mail-address) to use as my identity when sending a mail. I sniffed with wireshark, and with my standard identity, I see the message appended to "Sent", like I expect. If I use an alias, I see a folder being created : "INBOX.Sent", and then the message is appended there. Why the difference ? I'm trying to debug this but dovecot does not help much. I tried rawlog but there is no output (that I see) from it, no log-files in my maildir. Any hints how to proceed ? Output op dovecot -n : # 1.2.5: /etc/dovecot/dovecot.conf # OS: Linux 2.6.22.19-0.4-default x86_64 openSUSE 10.3 (X86-64) base_dir: /var/run/dovecot/ log_path: /var/log/dovecot log_timestamp: %Y-%m-%d %H:%M:%S listen: *:143 ssl_listen: *:993 ssl_ca_file: /etc/postfix/certificate/cacert.org.pem ssl_cert_file: /etc/postfix/certificate/mailbox.pem ssl_key_file: /etc/postfix/certificate/mailboxkey.pem disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot//login login_executable: /usr/lib/dovecot/imap-login first_valid_uid: 499 last_valid_uid: 499 mail_location: maildir:/var/vmail/%d/%u mail_debug: yes mail_executable: /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap lda: postmaster_address: postmaster(a)mydomain.com sendmail_path: /usr/lib/sendmail auth_socket_path: /var/run/dovecot/auth-master mail_plugins: cmusieve auth default: mechanisms: plain login user: nobody verbose: yes debug: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.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: 432 user: vmail group: vmail Kind regards, Koenraad Lelong.

[Dovecot] Multiple postfix + single dovecot - optimal configuration
by Tomek 26 Oct '09

26 Oct '09

Hello, I want to setup dovecot with two postfix servers on three machines: - dovecot - with huge amount of disk space - where all user emails will be kept, - postfix1 - with greylisting, amavisd-new (spamassassin, clamav, etc), with mysql backend, - postfix2 - same as postfix1. MX priority will be set to the same value for both postfix machines. For now I don't know how to "glue" these severs: - if I should install dovecot on both postfix and use third servers as a NFS share? - or maybe it is possible to communicate with dovecot on third server via LMTP? - or should I run third postfix daemon (without antyspam etc - simple configuration) on the same machine as dovecot only for delivering local mails? I will be grateful for any advice, howto or good practices example. -- Regards, Thomas.

[Dovecot] protocol configure confusion
by Stewart Dean 26 Oct '09

26 Oct '09

The docs say: > > *protocol*s = imap *imaps* > *Protocol*s we want to be serving: imap *imaps* pop3 pop3s If you > only want to use dovecot-auth, you can set this to "none". > and..... > > If you want to specify ports for each service, you will need to > configure these settings inside the *protocol* imap/pop3 { ... } > section, so you can specify different ports for IMAP/POP3. For example: > > # *protocol* imap { > # listen = *:10143 > # ssl_listen = *:10943 > # .. > # } > So if I want to run both imap and imaps AND configure the port, do I do: # *protocol* imap { # listen = *:143 # ssl_listen = *:10943 # } OR # *protocol* imap { # listen = *:143 # } # *protocol* imaps { # listen = *:993 # }

[Dovecot] Rotating the dovecot log file
by Jerry 24 Oct '09

24 Oct '09

Using FreeBSD-7.2, I am attempting to configure the system newsyslog utility to rotate the dovecot.log file. I would prefer to use the system utility rather than the one described on the dovecot wiki for rotating the file. Unfortunately, it is not working. This is the error message that is spawned: newsyslog: illegal signal number in config file: /var/log/dovecot.log root:wheel 0666 1 * $M1D0 CJ /var/run/dovecot/master.pid USR1 Does anyone have an idea how to get this to work?

[Dovecot] v2.0.alpha2 released
by Timo Sirainen 23 Oct '09

23 Oct '09

http://dovecot.org/releases/2.0/alpha/dovecot-2.0.alpha2.tar.gz http://dovecot.org/releases/2.0/alpha/dovecot-2.0.alpha2.tar.gz.sig Changes since alpha1: - All debug messages are now logged to debug log (debug_log_path setting, defaults to info_log_path). Patch by Pascal Volk. - Added support for SORT=DISPLAY IMAP extension. - Added doveadm who command for listing currently logged in users. - ssl_ciphers_list: Disable anonymous and export ciphers by default. - mail_chroot can now contain %variables (e.g. /home/%u) - fixed a bad maildir crashing bug - ssl-params is now run with +15 priority when generating the ssl parameters - Redesigned how login processes log in and create imap/pop3 processes. This fixes several settings and some other problems, plus it's now also possible for a single imap/pop3 process to handle multiple connections. If you want to try this, modify master.conf: service imap { # comment out: #service_count = 1 # This should be at least the number of CPUs, maybe more (2-3x?) process_min_avail = 4 # Limit the number of clients a single process can handle. # Disk IO is blocking, so some commands can take a while. client_limit = 5 } It currently doesn't even try to group same user's connections to same process, they'll just go randomly to whichever process manages to accept it first. Some day perhaps there should be a new service in the middle that keeps track of existing connections and forwards new ones to right mail processes. v2.0.beta1 TODO list: - master.conf has to be somehow put into defaults, so doveconf -n doesn't show its contents. an example master.conf would be minimal and show only those settings that admin might want to change (and those would show up in doveconf -n) - verbose_proctitle=yes is now quite useless because of the imap/pop3 process creation change. Probably enable linux-proctitle-hack and start changing the proctitle much more often. For example it could contain the command that's currently being run by user. And login processes could contain how many client connections they currently have. And other processes too something similar.. - change plugin hook design to allow multiple users in same process to run different plugins See alpha1 release announcement for more about these TODO: - v1.x config backwards compatibility - dsync is buggy - config process is slow - tcp-wrappers support

[Dovecot] Capability info in hello message not complete?

Hi, one Fedora user complains about not some troubles after update to dovecot 1.2. He suspects wrong capability information given by dovecot 1.2 In dovecot.conf he uses imap_capability= option. While response to 'A CAPABILITY' respects imap_capability value, the capability info in hello message does not. for imap_capability=IMAP4 IMAP4rev1 ACL NAMESPACE CHILDREN SORT QUOTA THREAD=ORDEREDSUBJECT UNSELECT IDLE STARTTLS AUTH=PLAIN A CAPABILITY response is: * CAPABILITY IMAP4 IMAP4rev1 ACL NAMESPACE CHILDREN SORT QUOTA THREAD=ORDEREDSUBJECT UNSELECT IDLE STARTTLS AUTH=PLAIN but hello message is: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready.

[Dovecot] HA Dovecot Config?
by dovecot＠corwyn.net 23 Oct '09

23 Oct '09

Hi! I'm currently running Dovecot 1.1.8 on a HP server using CentOS 5.2 as my IMAP server, receiving mail from postfix, and also using squirrelmail as the frontend. As I look at upgrading the mail server, I'd like to change to a higher availability configuration (where the server can fail and I don't have to reconfig my imap users). For the SMTP that's easy, because I can use multiple MX records, and I can redirect a port forward from one server to another. But IMAP doesn't have the same functionality, because it's the storage that matters. What's the "best" way to do that? Clustered servers using a SAN? NAS? some sort of appliance in front? Suggestions? Thanks! Rick Rick Steeves http://www.sinister.net In reality nothing is more damaging to the adventurous spirit within a man than a secure future - Alexander Supertramp

[Dovecot] Need a little shadow to MySQL conversion help
by Marc Perkel 22 Oct '09

22 Oct '09

Excuse me for being stupid and confused. I'm trying to convert my dovecot install from passwd-file to mysql. I have a single table called "users" that has 3 fields, user_name, domain_name and password. The data came from passwd/shadow files so it uses the same password encryption as the shadow files do. The directory where the email is stored is calculated elsewhere and not stored in the database. The UID and GID are both mail for all virtual users. The user logs in passing the full email address and the password. So - what would be the config for using MySQL? Do I even need a userdb? If so - what would it be? Thanks in advance.

[Dovecot] VZW Blackberry BIS problems?
by B. Cook 22 Oct '09

22 Oct '09

Ever since Columbus day things have been strange with my two dovecot servers, according to my Blackberry users. We do not have a BES just the standard BIS that comes with a personal account. Several people have told me that since that Monday that they get occasional duplicate copies of messages which only appear singularly in their Maildir inboxes. I myself even called VZW and got transferred to RIM themselves where they 'reset' my account; (same as me going into the BIS server and deleting and adding again) only to have the same thing happen; again occasionally.. Below is relevant dovecot info.. -r-xr-xr-x 1 root wheel 164064 Oct 1 17:16 /usr/local/sbin/dovecot (date it was built; prior to any problems.. *whew*) ;) 1 # 1.2.4: /usr/local/etc/dovecot.conf 2 # OS: FreeBSD 7.2-RELEASE-p3 i386 3 ssl_cert_file: /usr/local/etc/lighttpd/ssl/mail.poughkeepsieschools.org.pem 4 ssl_key_file: /usr/local/etc/lighttpd/ssl/mail.poughkeepsieschools.org.pem 5 disable_plaintext_auth: no 6 verbose_ssl: yes 7 login_dir: /var/run/dovecot/login 8 login_executable: /usr/local/libexec/dovecot/imap-login 9 login_greeting: mail.poughkeepsieschools.org OK 10 first_valid_uid: 89 11 last_valid_uid: 89 12 first_valid_gid: 89 13 last_valid_gid: 89 14 maildir_copy_preserve_filename: yes 15 mail_plugins: quota imap_quota 16 imap_client_workarounds: delay-newmail outlook-idle tb-extra-mailbox-sep 17 auth default: 18 mechanisms: plain login 19 user: vpopmail 20 passdb: 21 driver: vpopmail 22 userdb: 23 driver: vpopmail 24 socket: 25 type: listen 26 client: 27 path: /var/run/dovecot/auth-client 28 mode: 438 29 plugin: 30 quota: maildir:User quota 31 expire: Trash 7 Spam 30 Now what does not show here is something that I put in that it looked like it was supposed to help but didn't.. mailbox_idle_check_interval = 30 after looking around at other people complaining about BIS and possible dovecot issues it seemed that that entry was the 'magic' the BIS was missing; except I never had it and never had troubles. I'm assuming this is a BIS issue of some sort, but I can't tell. After looking on the wiki I didn't see anything that says "BIS users look here for tips.. " So I'm assuming there aren't any; I think it should just work with the IMAP server.. Any help would be appreciated as everyone thinks this is 'our problem' and "if we had an exchange server we wouldn't be having these problems.." Thanks in advance..

I rebuilt the binaries on our hosts with optimization disabled, and I'm still waiting for it to reoccur so I can gather file descriptor information and a core. I don't have the leak-detect patch applied. Let's see what Timo has to say about that log file bit.

[Dovecot] NFS random redirects
by Thomas Hummel 22 Oct '09

22 Oct '09

Hello, Dovecot documentation states that the "random redirects to multiple servers" NFS solution is to be avoided and I'm investigation the actual risks of it and a way to put it to test. I'm running dovecot-1.2.6 with Maildir (indexes, mailboxes and control files are all on NFS) and I'm using procmail instead of deliver as the LDA. 1. Documentation says : "Dovecot locks the maildir while doing modifications to it or while looking for new messages in it" and then mention the "dovecot-uidlist.lock" dotlock file. a) if that file fcntl'ed in addition (i.e. dotlocked + fcntled or just dotlocked) ? b) is that file THE way to lock the Maildir mentionned above or is it just something else used only for updating that particular file (i.e. is Maildir locked in some way + dovecot-uidlist.lock created or just dovecot-uidlist.lock created) ? 2. Documentation says : "NFS caching is a big problem when multiple computers are accessing the same mailbox simultaneously" I guess it's because of the dotlocks files and not fcntl locking ? Is there anything else than dovecot-uidlist which is dotlocked ? If yes, is it dotlocked only or dotlocked and fcntled ? 3. Documentation says : "Dovecot v1.1 flushes NFS caches when needed if you set mail_nfs_storage=yes" How can a program flush the NFS caches ? By which (system) call ? 4. Documentation says : "Besides the NFS cache problems described above, mailbox contents can't be cached as well in the memory either." Is it about in-memory indexes or part of indexes loaded into memory ? 5. How can I torture-test concurrent access to the same mailbox through 2 dovecot servers ? I don't see imaptest.c anymore on http://dovecot.org/tools but I see 2 nfs_test ? Is there some command line options I should use ? 6. when and why can a random redirect to multiple server can cause mailbox corruption ? On flags only or on content as well ?

[Dovecot] deliver+sieve: Destination address (-a) parsing changes
by Frank Behrens 21 Oct '09

21 Oct '09

When I upgraded my old, long running dovecot 1.1 to newer dovecot-1.2.4 + doevecot-sieve- 0.1.12 I observed a change in destination address (-a) parsing. Old behaviour: When Timo introduced this feature (http://www.dovecot.org/list/dovecot/2007-September/025813.html) it was possible to hand over only the detail part. In my sendmail configuration I used "-a +$h", where $h contains the detail part and may be empty. By default sendmail can call the delivery agent with the following information: $u: The recipient user (always set) $h: Detail part, may be empty $g: The sender address (relative to the recipient). New behaviour: The current sieve version needs a complete address with local- and domain-part. Otherwise we get a warning like deliver(user): sieve: envelope recipient address 'user' is unparseable. The problem is, that the domain part is not always available, e.g. for local delivered emails. This is the main problem, although the setup could be simplified if deliver would accept the old syntax. I'm going to make modifications to sendmail to be able to have all address information available, but this will not solve the problem with missing domain. Now comes my question: Is it better to enhance the address parsing in sieve plugin or should I use a wrapper around deliver? The latter is not very difficult, but introduces an additional process (that may fail). Regards, Frank -- Frank Behrens, Osterwieck, Germany PGP-key 0x5B7C47ED on public servers available.

[Dovecot] Question about IMAP IDLE (and Palm Pre)

Hello, i try to understand, how it works (IDLE). Try to get it successfully work with my new Palm Pre ;-) which looks like to have a lot issues wir imap... so i'll blame not dovecot for the issues. Sent a mail, from googlemail. processed by dovecot ad 12:11. what me now confusing, is, that there in the out-log is nothing visible, I expected, to see there was sent an notification, there was a new mail. Do i miss something? After arounde 15 minutes the Palm sent a "DONE" and reconnect. then the messages was received.

[Dovecot] Unknown setting: driver
by Rodolfo González González 20 Oct '09

20 Oct '09

Hi, the conversion from courier was done without problems, but now I have a problem with my auth config. I followed the sql example included in the latest dovecot source, and put driver=mysql in dovecot.conf (outside any section), and now I get: --- Error: Error in configuration file /usr/local/etc/dovecot.conf line 50: Unknown setting: driver Fatal: Invalid configuration in /usr/local/etc/dovecot.conf Starting DovecotError: Error in configuration file /usr/local/etc/dovecot.conf line 50: Unknown setting: driver Fatal: Invalid configuration in /usr/local/etc/dovecot.conf --- So I'm lost... what's wrong? if I followed the example :o Then, another question: I had to go back to courier so my users still can work, but I already created the files using the migration script: do I need to rerun the migration script? or what do I need to do when I manage to fix the error above and run dovecot? Thanks.

[Dovecot] clarify 'type', 'executable' & 'path' in 2.0 master.conf?
by PGNet Dev 19 Oct '09

19 Oct '09

@2.0's master.conf, there's, e.g., service config { type= config executable =config unix_listener { path = config mode = 0666 } } can someone please explain function/usage for the 'type', 'executable' & 'path' fields? and, for any file paths, are the presumed to be _relative_ to the dovecot executable? in $PATH? can they accept full/absolute paths? thanks.

[Dovecot] Dovecot deliver with AD LDAP userdb
by Mark Schaub 19 Oct '09

19 Oct '09

Good Afternoon, I have my virtual users stored in an Active Directory database. As far as mail info goes the 2 important fields are: mail (their primary email address) and otherMailbox (a multivalue attribute containing their mail aliases). Right now all email addresses belong in the same domain and there are no immediate plans to change this. If I use Postfix to do the lookups and delivery only using Dovecot for passdb Pam driver and a static userdb then everything delivers fine to mail and otherMailbox addresses. I have been working on switching over to Dovecot's deliver process in order to integrate sieve capability. I have configured userdb ldap and passdb ldap in Dovecot and have set up master and client sockets. Before I describe my problem let me show you my configuration (as I think the dovecot-ldap.conf in particular needs to be explained). Here are the important parts of dovecot.conf: auth default { socket listen { master { path = /usr/var/run/dovecot/auth-master mode = 0666 user = vmail group = vmail } client { path = /var/spool/postfix/private/auth mode = 0666 user = postfix group = postfix } } passdb ldap { args = /etc/dovecot-ldap.conf } userdb ldap { # Path for LDAP configuration file, see doc/dovecot-ldap-example.conf args = /etc/dovecot-ldap.conf } and my dovecot -n: lda: postmaster_address: postmaster(a)sau24.org mail_plugins: sieve auth default: mechanisms: plain login debug: yes passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 438 user: postfix group: postfix master: path: /usr/var/run/dovecot/auth-master mode: 438 user: vmail group: vmail plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/sieve sieve_storage: ~/sieve Further, here is my dovecot-ldap.conf: hosts = delldb.sau24.org:3268 base = dc=sau24, dc=org ldap_version = 3 dn = cn=Mail User,cn=Users,dc=sau24,dc=org dnpass = secret auth_bind = yes scope = subtree user_attrs = sAMAccountName=home=/home/vmail/%$,=uid=501,=gid=501 pass_attrs = sAMAccountName=user user_filter = (&(objectclass=person)(|(sAMAccountName=%n)(mail=%n@sau24.org)(otherMailbox=%n@sau24.org))) pass_filter = (&(objectclass=person)(|(sAMAccountName=%n)(mail=%n@sau24.org)(othermailbox=%n@sau24.org))) Now, you'll notice that the user_filter and pass_filter have the domain statically placed after the mail and othermailbox attributes. This reason for this is that this ldap configuration is used for both authentication purposes and local delivery, so its not always being passed the domain info (for authentication it gets the users IP address). Since all my users are on the same domain I can statically set this here. This setup authenticates users to imap and pop (users use their sAMAccountName as their username when they log in), and pulls their correct home directory. Checking mail is not a problem at all. Further, this setup will deliver mail correctly to mail addressed to the value in the "mail" attribute. The problem seems to be in the otherMailbox attribute, it cannot lookup the users sAMAccountName based off of the otherMailbox field. Here is what it looks like in the logs for mail sent to my "mail" attribute (mark.schaub(a)sau24.org) Oct 14 12:36:19 auth(default): Info: master in: USER 1 mark.schaub(a)sau24.org service=deliver Oct 14 12:36:19 auth(default): Info: ldap(mark.schaub(a)sau24.org): user search: base=dc=sau24, dc=org scope=subtree filter=(&(objectclass=user)(|(sAMAccountName=mark.schaub)(mail=mark.schaub@sau24.org)(otherMailbox=mark.schaub@sau24.org))) fields=sAMAccountName Oct 14 12:36:19 auth(default): Info: ldap(mark.schaub(a)sau24.org): result: sAMAccountName(home=/home/vmail/%$)=/home/vmail/mschaub Oct 14 12:36:19 auth(default): Info: master out: USER 1 mark.schaub(a)sau24.org home=/home/vmail/mschaub uid=501 gid=501 Oct 14 12:36:19 deliver(mark.schaub(a)sau24.org): Info: sieve: msgid=<6b71e3a70910140936v4e8cd6fdwd847a1721a9d9786(a)mail.gmail.com>: stored mail into mailbox 'INBOX' But this is what I get when I try to send to an address listed in my otherMailbox field (tech(a)sau24.org) Oct 14 12:30:58 auth(default): Info: master in: USER 1 tech(a)sau24.org service=deliver Oct 14 12:30:58 auth(default): Info: ldap(tech(a)sau24.org): user search: base=dc=sau24, dc=org scope=subtree filter=(&(objectclass=user)(|(sAMAccountName=tech)(mail=tech@sau24.org)(otherMailbox=tech@sau24.org))) fields=sAMAccountName Oct 14 12:30:58 auth(default): Info: ldap(tech(a)sau24.org): Unknown user Oct 14 12:30:58 auth(default): Info: master out: NOTFOUND 1 As a test I tried modifying my dovecot-ldap.conf to use different fields instead of otherMailbox. Sending to some of those attributes worked, others didnt. I could use the "sn" and "givenName" attributes, but "postalCode" and "title" would give the same error as otherMailbox. My question is this: is there something wrong with my configuration or can Dovecot only query certain fields in the user_attr string? Thanks, ~ Mark

[Dovecot] Released Sieve v0.1.13 for Dovecot v1.2.6
by Stephan Bosch 19 Oct '09

19 Oct '09

Hello Dovecot users, After about a month of silence, I finally release a new version of Pigeonhole Sieve. This release fixes problems in the multiscript support and improves the body extension further towards RFC compliance. The body extension still needs work, however, since some content types still give erroneous results. Changelog Sieve v0.1.13: + Body extension: implemented proper handling of the :raw transform and added various new tests to the test suite. However, :content "multipart" and :content "message/rfc822" are still not working. + Fixed race condition occuring when multiple instances are saving the same binary (patch by Timo Sirainen). + Test suite: added support for testing multiscript execution. - Made compiler more lenient towars missing CRLF at the end of the script in a hash comment. - Body extension: don't give SKIP_BODY_BLOCK flag to message parser, we want the body! (patch by Timo Sirainen). - Fixed handling of implicit side effects for multiscript execution. - Fixed bugs in multiscript support; subsequent keep actions were not always merged correctly and implicit side effects were not always handled correctly. - Fixed a segfault bug in the sieve-test tool occuring when compile fails. - Fixed segfault bug in action procesing. It was triggered while merging side effects in duplicate actions. - Fixed bug in the Sieve plugin that caused it to try to stat() a NULL path, yielding a 'Bad address' error. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.13.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.13.tar.gz.sig Refer to http://pigeonhole.dovecot.org for more information. Have fun testing the new release and don't hesitate to notify me when there are problems. Releases for Dovecot v2.0 are still under development... Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] migrate courier to dovecot script - questions about directory structure
by Ross 17 Oct '09

17 Oct '09

Hi all, Im in the process of moving about 7000 users across from courier to dovecot. Both Maildir setups. The migration script works a treat, but I need a slight change to it. Couriers directory structure looks ike this: /home/vmail/<domain.com.au>/<username>/cur/ /home/vmail/<domain.com.au>/<username>/new/ /home/vmail/<domain.com.au>/<username>/tmp/ /home/vmail/<domain.com.au>/<username>/maildirsize /home/vmail/<domain.com.au>/<username>/courier* etc.. Dovecot looks like this: /home/vmail/<domain.com.au>/<username>/Maildir/cur/ /home/vmail/<domain.com.au>/<username>/Maildir/new/ /home/vmail/<domain.com.au>/<username>/Maildir/tmp/ So the issue is, there is an additional Maildir directory in the structure. Now the migration script works fine, however when the migration is completed, I have to manually add the Maildir directory into the structure, which is going to take a little too long :) Is there something in the script that can add this ? Is there a way to perhaps use the script to add the Maildir part ? My initial plan was to copy the entire /home/vmail/<domain.com.au>/* across to the dovecot server and run the migration script. However, without the Maildir directory in the structure it won't work. Has anyone run into this issue ? How did you solve it ? -- Regards Ross fatboy:/tmp# dovecot --version 1.0.15 fatboy:/tmp# dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s 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: mail mail_location: maildir:/var/vmail/%Ld/%Ln/Maildir 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 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv namespace: type: private separator: . prefix: INBOX. inbox: yes auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: static args: uid=5000 gid=5000 home=/var/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir:storage=51200

Re: [Dovecot] Dovecot deliver with AD LDAP userdb [SOLVED]
by Mark Schaub 16 Oct '09

16 Oct '09

> Then there's something different what Dovecot and ldapsearch does. They > have the same dn, dnpass, neither uses tls, same base, deref, scope? > I figured it out, there certainly is something different! The AuthDatabase/LDAP documentation on the Dovecot Wiki says "When connecting to AD, use port 3268". Port 3268 is used for Global Catalog searching. By default the Active Directory Global Catalog wouldn't include attributes like otherMailbox, but would include mail and sn. The solution here would be to either use port 389 and search the domain like ldapsearch or to add the otherMailbox attribute (or any others I want to search on) to the global catalog. It might be worth updating the wiki to mention the reasoning behind using port 3268 and the implications it can cause. Thanks for the help!

[Dovecot] Sendmail and Dovecot Delivery to Virtual Users
by Philipp Hunold 16 Oct '09

16 Oct '09

I'm new to dovecot and sendmail and my server doesn't forward mails to 'dovecot deliver' at all. I was reading http://wiki.dovecot.org/LDA/Sendmail and this http://www.dovecot.org/list/dovecot/2009-June/040353.html from the mailling list but I could figure it out myself. I someone could point me into the right direction. I'm confused with the config for LDA. Basically what I want is every message coming in go to 'deliver' except if there's no dovecot user of course. I'm using 'local_procmail' feature right now, but I tried to comile the dovecot Mailer also. Anyway the dovecot 'deliver' itself works fine. But I cannot receiving emails or messages don't go anywhere. All the debugging I do with telnet right now. first I got 'User Unknown' errors in the maillog so I thought I just missing an alias/virtuser entry. So I create one and forward those to procmail. But now the messages don't go anywhere and the status is sent and I don't seem them in the /var/log/dovecot-deliver.log either, so they are stuck in the middle somewhere. Oct 16 14:26:26 sendmail[29939]: n9GIQQAh029939: to=|/usr/bin/procmail, ctladdr=<mail.address> (8/0), delay=00:00:00, xdelay=00:00:00, mailer=prog, pri=31420, dsn=2.0.0, stat=Sent I don't seem to understand how the message get to dovecot's 'deliver' from sendmail. Some questions I have which may help to solve the problem myself: - how can I tell the LDA to lookup dovecot users too? to it would accept it? - do I need aliases therefore for each dovecot users? - What would the alias look like or is this the wrong way to do it? "test.user: |/usr/bin/procmail" ? - what's the procmail recipe which would work for maildir:/home/vmail/%u mail_location?

[Dovecot] Sieve question
by CJ Keist 16 Oct '09

16 Oct '09

If there is a separate sieve mailing list let me know. But have question if someone else has done this or not. Right now I have web form people use to setup their vacation replies using Sieve (1.1.6). The form alows them to set what they want their reply address to be, whether to send the reply once, weekly or bi-weekly. I would like to setup another option to let them set the date in which to de-active the vacation replies automatically. Right now they have to remember to log back into the form to turn off the vacation reply. Has anyone set something like this up? -- C. J.

If the mailbox is large, it may take time to re-generate index and put lock on inbox file until it's done. However, it should not for smaller mailbox file. Deleting index files did not help. The workaround is rename the mailbox file and copy it to ~/mail folder and let MTA re-create the mailbox. Then let mail client subscribes to the new temp mailbox.

[Dovecot] Dovecot can't find users' sieve files
by Bartosz Fenski aka fEnIo 16 Oct '09

16 Oct '09

Hello. I asked for help on #dovecot but one suggestion I got was setting sieve variable explicitly but unfortunatelly that didn't help. I'm trying to set up sieve to be able to use vacation module. So in the lda section I put: mail_plugins = sieve And in plugins section: sieve = ~/.dovecot.sieve Then I put .dovecot.sieve file in the user's directory. This is what I get in Dovecot's log when trying to deliver to that mailbox: 2009-10-16 18:37:52 deliver(test(a)domain.pl): Error: sieve: stat((null)) failed: Bad address (using global script path in stead) 2009-10-16 18:37:52 deliver(test(a)domain.pl): Info: msgid=<20091016163757.GK19565(a)asdy.pl>: saved mail to INBOX Some infos about system: Dovecot 1.2.5 Debian squeeze/testing x86_64 ext3 (root)~#dovecot -n # 1.2.5: /etc/dovecot/dovecot.conf # OS: Linux 2.6.30-1-amd64 x86_64 Debian squeeze/sid ext3 log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/home/vmail/%u 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_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 lda: postmaster_address: postmaster(a)domain.pl mail_plugins: sieve log_path: /var/log/dovecot-deliver.log auth_socket_path: /var/run/dovecot/auth-master auth default: passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.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: vmail group: vmail plugin: sieve: ~/.dovecot.sieve (root)~# And dovecot-sql.conf: driver = pgsql connect = host=localhost dbname=postfix user=postfix password = xxxxxxxx password_query = \ SELECT local_part, password \ FROM mailbox WHERE local_part = '%n' AND active = 't' user_query = \ SELECT maildir, 5000 AS uid, 5000 gid \ FROM mailbox WHERE local_part = '%n' AND active = 't' Delivering works perfectly but I can't figure out why it's not able to find that .dovecot.sieve file: (root@germany)~#ls -al /home/vmail/test(a)domain.pl/.dovecot.sieve -rw-r--r-- 1 vmail vmail 314 2009-10-16 13:09 /home/vmail/test(a)domain.pl/.dovecot.sieve (root@germany)~# Any help would be very appreciated. regards fEnIo -- ,''`.

[Dovecot] Better APPEND performance
by Mike Abbott 16 Oct '09

16 Oct '09

Moving a large number of messages into an IMAP folder on a dovecot server takes quite a long time. This is a popular operation for users migrating their stored messages from their old mail servers through a mail user agent, and it causes a poor first impression of dovecot. I'd like your help to speed this up. I have studied this problem in recent versions, including 1.1.[17-19] and 1.2.[4-6] but I'll focus on 1.2.6, using Maildir++. It seems to be caused by O(n^2) behavior in maintaining the UID list, where n is the number of messages. The client selects a folder then sends thousands of individual APPEND commands (no use of multiappend unfortunately). These cause dovecot to behave as follows: 1. For every other APPENDed message, dovecot appends the new UID to the list quickly. No problem here, this is fast. 2. For every other other APPENDed message, dovecot scans the entire UID list. This is an O(n) algorithm. Since it happens every n/2 times it causes O(n^2) behavior across n consecutive APPENDs. More specifically, 1. APPEND a message to a folder that already contains 30,000 messages. maildir_uidlist_refresh_fast_init() takes the fast path. 2. APPEND a second message to the same folder. maildir_uidlist_refresh_fast_init() takes the slow path: it populates the uidlist->files hash table with all the UIDs, checking for duplicates. At the end of the command maildir_uidlist_deinit() destroys the hash table. Note how this APPEND takes much longer than #1. 3. APPEND a third message to the same folder. Just like #1. 4. APPEND a fourth message to the same folder. Just like #2, and since #2 destroyed the hash, it has to do all that work over again. 5. And so on. What can be done to make maildir_uidlist_refresh_fast_init() choose the fast path more often?

[Dovecot] v2.0.alpha1 released
by Timo Sirainen 16 Oct '09

16 Oct '09

http://dovecot.org/releases/2.0/alpha/dovecot-2.0.alpha1.tar.gz http://dovecot.org/releases/2.0/alpha/dovecot-2.0.alpha1.tar.gz.sig So here's the first alpha version of Dovecot v2.0. There are still a couple of things left to do, but in general it should work for most people. I started using it for my own mails a few days ago and it seems to work without errors. Largest changes since v1.2: * Global ACLs are now looked up using namespace prefixes. For example if you previously had INBOX. namespace prefix and a global ACL for "INBOX.Sent", it's now looked up from "INBOX.Sent" file instead of "Sent" as before. + Redesigned master process. It's now more modular and there is less code running as root. + Configuration supports now per-local/remote ip/network settings. + dsync utility does a two-way mailbox synchronization. + LMTP server and proxying. + Added mdbox (multi-dbox) mail storage backend. + doveadm utility can be used to do all kinds of administration functions. Old dovecotpw and *view utilities now exist in its subcommands. Some things left to do: - Do something about backwards compatibility with v1.x. Either make it read v1.x config files or provide some config conversion utility. - dsync still has some bugs - config process is a bit too slow. config handling in general could use some caching all around. no need to ask configuration for each login unless there are per-remote-ip settings. - some kind of an optional connection policy server could be useful. mainly to finally implement tcp-wrappers support. - mail_uid, mail_gid, mail_chroot settings don't really work now. I think this actually needs a bit larger change, which is probably a good idea in any case: After successfully authenticating, login process needs to get imap/pop3 process executed. Currently this is done by transferring the connection fd to master process, doing userdb lookup and then forking and execing the imap/pop3 process. The new behavior I'm thinking is that after auth, login process would connect to imap/pop3 unix socket in the login/ directory. That would cause master process to fork a new imap/pop3 process (running as root). Login process would send the necessary auth information via the unix socket, possibly transfer also the fd, and imap/pop3 would do the userdb lookup and then drop privileges. This change has some pros: - Master process will no longer temporarily hold some extra fds and use extra memory during auth lookups. If auth process is hanging these could cause problems. - Master process will no longer have any special auth handling code and I can remove type=auth-source and type=auth services. - Of course fixes the mail_* setting issue, because all of this is now done by imap/pop3 process, which knows about these settings. - Creating support for "multiple imap/pop3 post-login connections in a single process" should be pretty easy to implement with this. The imap/pop3 unix socket just needs to be listened by a new process in the middle that keeps track of what imap/pop3 processes exist and can redirect the new connections to those. But also some cons: - drop_priv_before_exec=yes no longer works, unless the uid/gid is hardcoded to the service {} block. - Each imap/pop3 process needs to do a connect() to auth server at startup, adding a bit to the latency.

[Dovecot] "From" address in vacation response on hosted domains with dovecot/postfix/sieve
by Peter Borg 16 Oct '09

16 Oct '09

Hi, I have a working dovecot/postfix/sieve configuration: Ubuntu 8.04 LTS Dovecot 1.2.6 Sieve 0.1.12 Postfix 2.5.1 The server is configured to host multiple domains. All mail delivery, logins and aliases work absolutely perfectly. There's only one weirdness: the 'From' address in vacation responses. If a message is sent to user(a)hosteddomain.com the response comes from user-hosteddomain.com(a)hostingservername.com Obviously it's doing what one would expect in that it's taking the username (user-hosteddomain.com) and appending the local host name (hostingservername.com) This isn't great from the perspective of the hosted user, however, who'd much rather their vacation message was sent from their actual email address. Clearly I can modify this by using a ':from' statement in each relevant sieve file, but I can't rely on users' mail clients to set this (as not all do) and the webmail client in use on the server doesn't set this. I can almost certainly implement some kind of hack using this, but I'd rather not. So how does sieve determine the from address to use if it's not explicitly set in the sieve script for the user, and how can I direct sieve to determine the address differently, preferably with a central configuration option that will apply to all users regardless of domain.....? Regards, Peter.

[Dovecot] Internal server
by Guy 16 Oct '09

16 Oct '09

Hi, I'm looking at doing some testing for a little internal IMAP server. Basically use fetchmail (or some such thing to bring in mail) so users have a local IMAP server to connect to. I'm interested in trying out mdbox, but since I'd have to use dovecot 2.0 with it I thought I'd just check what peoples' experience with 2.0 is like so far? Is it reasonably stable already? Is there also a page showing the differences in config for dbox over maildir? Or is it simply just the change in mail_location and nothing else? Thanks Guy -- Don't just do something...sit there!

[Dovecot] Expire plugin: wrong mailbox separators in database?
by Andreas Ntaflos 16 Oct '09

16 Oct '09

Hi all, I'm experimenting with the expire plugin and seem have run into a small problem. I am using Dovecot 1.2.4 on a test server. The config is taken mostly verbatim from the expire plugin wiki page [1], using MySQL as a database. See below for detailed output. Namespace "private" has "/" configured as mailbox separator: namespace private { separator = / prefix = inbox = yes } The "expire =" section from dovecot.conf thus looks like this: plugin { expire = Trash 7 INBOX/Spam 8 INBOX/Spam/To-Discard 3 ... } Three mailboxes/folders are kept track of: Trash, INBOX/Spam and INBOX/Spam/Spam-To-Discard (this one holds messages that scored high enough to very unlikely be legitimate and should be deleted soon). But when a message is put into one of these folders the mailbox attribute of the expires table uses "." as mailbox separator: mysql> select * from expires; +-----------------+----------------------------+--------------+ | username | mailbox | expire_stamp | +-----------------+----------------------------+--------------+ | foo(a)example.org | INBOX.Spam.Spam-To-Discard | 1253114526 | | foo(a)example.org | INBOX.Spam | 1253114528 | +-----------------+----------------------------+--------------+ Consequently, expire-tool --test seems to choke on this: # dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Info: foo(a)example.org/INBOX.Spam.Spam-To-Discard: \ mailbox 'INBOX.Spam.Spam-To-Discard' removed from config Info: foo(a)example.org/INBOX.Spam: mailbox 'INBOX.Spam' \ removed from config When I manually update the mailbox attribute to use "/" as separator expire-tool seems to work correctly: # dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Info: foo(a)example.org/INBOX/Spam/Spam-To-Discard: stop, expire \ time in future: Wed Sep 16 17:22:06 2009 Using "." as separator in the "expire =" line doesn't work either: the expires table isn't written to at all when a message is put in one of the specified folders. Presumably because INBOX/Spam is the real mailbox but INBOX.Spam is monitored by the expire plugin and there is no INBOX.Spam to put in messages. So I believe this is not the expected behaviour? Or am I doing anything wrong? I'd rather not change the separator from "/" to "." in all the namespaces if that can be avoided.

[Dovecot] Error (IMHO) with --with-doc option
by Jacek Osiecki 16 Oct '09

16 Oct '09

Hi, I was trying to create complete rpm package for my system, containing dovecot 1.2.5 intregrated with dovecot-sieve and dovecot-managesieve. Finally I succeeded and it works great, but I found something that might be treated as wrong behaviour... When you run ./configure --with-docs=no, Makefile does not build docs anymore, but... installs them anyway :) It caused some troubles because rpmbuild complained about documents moved to <buildroot>/usr/share/doc/dovecot I have created a small patch that fixes this - hope it doesn't introduce any mess: diff -Nur 2/Makefile.in 1/Makefile.in --- 2/Makefile.in 2009-09-29 00:17:22.000000000 +0200 +++ 1/Makefile.in 2009-09-29 00:17:38.000000000 +0200 @@ -75,7 +75,7 @@ distclean-recursive maintainer-clean-recursive ETAGS = etags CTAGS = ctags -DIST_SUBDIRS = src doc +DIST_SUBDIRS = $(SUBDIRS) DISTFILES = $(DIST_COMMON) $(DIST_SOURCES) $(TEXINFOS) $(EXTRA_DIST) distdir = $(PACKAGE)-$(VERSION) top_distdir = $(distdir) Best regards, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944 I don't want something I need.

[Dovecot] Questions regarding dbox migration
by Mikkel 16 Oct '09

16 Oct '09

It has been my wish to move to dbox for a long time hoping to reduce the number of writes which is really killing us. Now I wonder what may be the best way of doing so. I'm considering some sort of intermediate migration where the existing Maildir users are changed to single-dbox and then later upgraded to 2.0 and changed to multi-dbox when it becomes stable. But is this a reasonable task to perform on a production system or at all? The alternative is to wait for 2.0 to become completely stable and then go all the way at once. I would however much prefer to take it one step at a time and I think it would be safer to start out with single-dbox as it appears less complex. Now the big question is whether multi-dbox and single-dbox are compatible formats. If a Maildir->dbox migration is made on a system running dovecot v. 1.1, would it then be trivial later changing to multi-dbox after upgrading to 2.0 or is a completely new migration then needed? Would this scenario be much different if the system is upgraded to version 1.2 before the change to single-dbox? Kind regards, Mikkel

[Dovecot] dovecot 1.2.6 fails to build with openssl < 0.9.8
by Paul Howarth 16 Oct '09

16 Oct '09

The update of ssl_proxy_get_security_string() in dovecot 1.2.6 has broken compatibility with openssl < 0.9.8 (e.g. on RHEL4) because the functions SSL_COMP_get_name and SSL_get_current_compression don't exist until openssl 0.9.8 (build fails at link time due to these symbols being unresolved). I've worked around this by reverting the function to the 1.2.5 version for now but I think a better solution would be to have a configure test for these functions and only include the SSL compression details when they're available. Cheers, Paul.

[Dovecot] is it possible to fetch messages for multiple users using a single account?
by Tony Smith 16 Oct '09

16 Oct '09

Dear list, I am running dovecot with LDAP. Each account has email in form abc(a)example.com, and messages are stored at /var/vmail/abc/Maildir. This is an external mail server, and I would like to use a cron job to fetch all messages to an internal server which has slow internet connection. It seems getmail supports multidrop retriever which might fit the bill. However I could not figure out how to set up an account that can be used to fetch all messages for all virtual accounts. Is it possible at all? thanks, Tony PS: here is my config: # dovecot -n # 1.1.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-openvz-amd64 i686 Debian 5.0.3 log_path: /var/log/dovecot.log protocols: pop3 pop3s imap imaps managesieve listen(default): * listen(imap): * listen(pop3): * listen(managesieve): 127.0.0.1:2000 ssl_cert_file: /etc/ssl/certs/cert.pem ssl_key_file: /etc/ssl/private/key.pem 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 login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_uid: 1000 mail_gid: 1000 mail_location: maildir:/%Lh/Maildir/:INDEX=/%Lh/Maildir/ mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota zlib mail_plugins(imap): quota imap_quota zlib mail_plugins(pop3): quota zlib mail_plugins(managesieve): 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 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): sieve_storage(default): sieve_storage(imap): sieve_storage(pop3): sieve_storage(managesieve): /var/vmail/sieve/%Ld/%Ln/ sieve(default): sieve(imap): sieve(pop3): sieve(managesieve): dovecot.sieve auth default: mechanisms: plain login default_realm: river-valley.com user: vmail passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/dovecot-auth mode: 438 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 438 user: vmail group: vmail plugin: quota_warning: storage=85%% /usr/bin/dovecot-quota-warning.sh 85 quota_warning2: storage=90%% /usr/bin/dovecot-quota-warning.sh 90 quota_warning3: storage=95%% /usr/bin/dovecot-quota-warning.sh 95 quota: maildir quota_rule: *:storage=100M expire: Trash 7 Trash/* 7 Junk 30 expire_dict: proxy::expire auth_socket_path: /var/run/dovecot/auth-master dict: expire: db:/var/lib/dovecot/expire/expire.db

[Dovecot] virtual Folder Plugin with "." Separator: [NONEXISTENT] Mailbox doesn't exist
by Elmar Weber 16 Oct '09

16 Oct '09

Hello, I've switched from courier-imap to dovecot to benefit from the virtual folder feature. I'm using dovecot 1.2.6 on Gentoo Linux. However, I', getting the message "[NONEXISTENT] Mailbox doesn't exist: <name>" from Thunderbird when I try to access any virtual folder. The relevant setup: mail_location = maildir:~/.maildir namespace private { separator = . inbox = yes hidden = yes list = yes } namespace private { prefix = virtual. separator = . location = virtual:~/.maildir/.virtual } I then created the folders ~user/.maildir/.virtual and ~user/.maildir/.virtual.test and placed a file in .virtual.test with the contents ====== * all ====== After a dovecot restart I'm getting the error message: "[NONEXISTENT] Mailbox doesn't exist: test" Where did I make the mistake in the configuration? Is the "." path separator a problem case? ciao, Elmar

[Dovecot] Missing folders
by John Moorhouse 16 Oct '09

16 Oct '09

I've recently had a oops with the system I was running dovecot on so have had to move it to a new machine, I've been able to retrieve the mbox files from the old machine, built the new machine and over wrote the new mbox files with the old one in maildir, connecting to the server via imap woeks but I can only see the mail in the inbox from the old mbox files, emails in sub directories (the sub directories arn't there), is there some command I need to run to get it to pass the mbox file to find the folders or it there another file I need to transfer form the old machine. (I'm assuming that all the emails for a user, including those in subfolders are within the single mbox file, particularly as I'm is very large) Thanks John

[Dovecot] Dovecot lock problem
by Simon Gao 16 Oct '09

16 Oct '09

Hi, We have a few users experiencing locking problem. When starting Thunderbird, there is no new emails in Inbox. Dovecot createa a lock file /var/spool/mail/<user>.lock. It never completes openning Inbox. If closing the mail client, the open imap session does not get closed, nor the lock file get deleted. Here are the errors in log: dovecot: Oct 13 11:18:35 Warning: IMAP(user1): Our dotlock file /var/mail/user1.lock was deleted (kept it 88 secs) dovecot: Oct 13 11:18:35 Error: IMAP(user1): file_dotlock_delete() failed with mbox file /var/mail/user1: No such file or directory We are running Dovecot 1.1.2. Any pointer to resolve this problem is appreciated. Simon

[Dovecot] MailDIR and expire plugin
by Jerry 16 Oct '09

16 Oct '09

All of the mailboxes on this system are in MailDIR format. None of the users delete mail off of the server after POPing their accounts. This is the present setting: expire = Trash 7 Spam 30 expire_dict = proxy::expire Is that correct for MailDIR style mailboxes? It doesn't appear correct; however, I have not been able to find any specific documentation on expire with MailDIR style mailboxes. I am assuming that the expire plugin will work since IMAP has not been implemented on this server. -- Jerry |::::======= gesbbb(a)yahoo.com |::::======= |=========== |=========== | QOTD: "Wouldn't it be wonderful if real life supported control-Z?"

[Dovecot] Dovecot 1.2.6 segfault in imap_fetch_begin
by Brandon Davidson 16 Oct '09

16 Oct '09

We recently upgraded from Dovecot 1.2.4 to 1.2.6 (with the sieve patches of course). Everything has been running quite well since the upgrade. The occasional issue with assert-crashing when expunging has gone away. However, one of our users seems to have triggered a new issue. She's been the only one to see it, but whenever she logs in, her imap process segfaults immediately. It appears that the crash is a null pointer deref in the array library, but I'm not sure what code is at fault for calling in without checking array validity... or even if I'm on the right track. Backtraces and some further information are available here. Cores available on request. http://uoregon.edu/~brandond/dovecot-1.2.6/bt.txt Thanks, -Brad

[Dovecot] Deliver - can't connect to .../auth-master
by iain＠brightbooks.co.uk 15 Oct '09

15 Oct '09

Dovecot version 1.1.11 Hi all, I'm having real trouble getting Getmail, which is configured to pick up mail from my ISPs mailhost, to put the mail in our local Maildirs, through Deliver. We're using virtual users so, if I am understanding correctly, Deliver needs to fetch this information from /var/run/dovecot/auth-master. The trouble is that Deliver doesn't seem to have the correct privileges to do so. Whenever Getmail tries to pass the mail to Deliver, the line: Oct 15 15:21:04 Domain deliver(user(a)domain.com): Can't connect to auth server at /var/run/dovecot/auth-master: No such file or directory appears in the Mail.err log. So far I've tried: # - Changing the privileges of the whole /var/run/dovecot/ folder, and its sub folders. I understand that this is only a workaround, as Dovecot changes the privileges back on restart, however it doesn't seem to work anyway. It changes the log result from 'No such file or directory' to 'Permission denied' (and sometimes 'Connection refused'). # - I tried setting the location of auth-master to /home/manager/dovecot in the dovecot-postfix.conf config files (and the dovecot.conf config, just in case), so I could control access to it, and its permissions, more closely. Again, no luck. The log file still shows that it is trying to access it through /var/run/dovecot ~ not sure why (I even went to the lengths of doing a search for /var/run/dovecot in the config files, to make sure I hadn't missed a rogue mention; nothing). Interestingly the file auth-master is created in the correct folder I've configured, but the log results still stay the same. Thanks in advance for any help getting this up and running.

[Dovecot] Two passwords: One for Dovecot IMAP and One for Dovecot SASL? Is it possible?
by Art Gray - Razorpoint 15 Oct '09

15 Oct '09

Greetings, Can Dovecot can handle separate authentication for receiving mail (IMAPS) and sending mail (SMTPS)? In the past, we used Dovecot IMAP for the receiving part and Cyrus SASL for the sending part. This allowed us to use two passwords with mail. Cyrus has grown too old and isn't useful anymore. Can Dovecot give us this functionality: two passwords, one for IMAP authentication and one for SASL authentication? If so, could you point me in the right direction to get this working? Thanks in advance, A

My configuration: # 1.2.4: /etc/dovecot.conf # OS: Linux 2.6.18-128.7.1.el5xen x86_64 CentOS release 5.3 (Final) ext3 protocols: imap imaps pop3 pop3s managesieve listen(default): *, [::] listen(imap): *, [::] listen(pop3): *, [::] listen(managesieve): *:20000 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 login_executable(managesieve): /usr/libexec/dovecot/managesieve-login login_greeting: Server ready. login_process_per_connection: no verbose_proctitle: yes first_valid_uid: 1 first_valid_gid: 90 last_valid_gid: 400 mail_privileged_group: mail mail_location: maildir:/home/%u/Maildir:INDEX=MEMORY:CONTROL=/conf/no-quotas/control/%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_executable(managesieve): /usr/libexec/dovecot/managesieve mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 mail_plugin_dir(managesieve): /usr/lib64/dovecot/managesieve 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): imap_client_workarounds(managesieve): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): lda: postmaster_address: postmaster(a)example.com mail_plugins: quota sieve auth_socket_path: /var/run/dovecot/auth-master auth default: debug: yes passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 511 plugin: quota: maildir trash: /etc/dovecot-trash.conf sieve: ~/.dovecot.sieve sieve_dir: ~/sieve sieve_extensions: +imapflags +notify dovecot-ldap.conf: hosts = ldap.example.com auth_bind = yes base = ou=people, dc=example, dc=com scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,telephoneNumber=quota_rule=*:storage=%$M user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=posixAccount)(uid=%u)(!(shadowExpire=*))) default_pass_scheme = CRYPT Imap shows correct quota, but dovecot lda doesn't reject mail and it gets overquota, maildirsize: 15728640S 28033743 4 If I add for example quota_rule = *:storage=20M to dovecot.conf it works, but I need per-user ldap quotas. It seems dovecot deliver ignores maildirsize.

[Dovecot] Investigating suspected cache corruption
by David Warden 14 Oct '09

14 Oct '09

Hi All, I'm running Dovecot 1.1.11 for a site of about 7000 active users with a Squirrelmail frontend. We migrated from Courier (big shout to everyone who worked on the wonderful part of the Dovecot wiki that deals with Courier migration) and I have been extremely happy with the performance gains Dovecot has given us. Not only is the IMAP part of Squirrelmail faster, but our same hardware is under far less stress than it was before the migration. To date, the only problem we have experienced is a seemingly random but significant slowdown in Squirrelmail's loading of the messages in a user's Inbox. Each time, I have been able to fix the problem by deleting the user's dovecot.index, dovecot.index.cache and dovecot.index.log files in the user's INDEX directory for their dovecot Inbox. I tried having users experiencing this problem log in to a test Squirrelmail box with mail_debug on, but I didn't see anything out of the ordinary and they report the same slowness on the test server. I don't see anything but normal login/logout IMAP lines in the production dovecot logs. I have hesitated a bit in posting to the list since this seems to be happening to a small percentage of users and it technically may be a problem with Squirrelmail, but the fact that I'm able to fix the problem by nuking Dovecot's index files has me concerned - does anyone have any suggestions for troubleshooting? My first idea when I get another one of these is to do a telnet IMAP session to Dovecot on one of the Squirrelmail boxes and see if I can get it to slow down when retrieving messages from the Inbox. We are using Maildir over NFS with the control/index files stored on NFS as well. We're doing FS quota over NFS using rquotad to query the NFS server for each user's quota. Here's the output of dovecot -n: # 1.1.11: /etc/dovecot.conf Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 1536).

[Dovecot] quota error dovecot 1.1.13
by Brightblade 14 Oct '09

14 Oct '09

Hi all, I've troubles with dovecot and quota. Sometimes mails to users are bounced because quota is full. I'm reading quota_rules from LDAP. One "du -h ." from maildir show user is under quota ( at 70 % more or less), less than 99%, i delete maildirsize and dovecot recreate it with ldap-quota value at first line and second line is current-quota mails. Current-quota is near quota max value so dovecot execute quota_warning (99%). Why is dovecot thinking quota is at 99% when du -h show me its value is near 70% ? any guess?

[Dovecot] backup using rsync
by Scott Murman 14 Oct '09

14 Oct '09

i'm trying to backup the dovecot Maildir files over a cifs share. source is a debian build, share is a readynas. i've been getting rsync: mkstemp 'filename goes here' failed: Not a directory (20) errors. rsync is v3.0. i believe this is related to the dovecot file naming convention that includes characters such as ':' in the filename. anyone else seeing similar behavior? a workaround? i can go to different backup strategies, but rsync is cheap and effective for my needs. thanks, -SM-

[Dovecot] Homedir for sieve/LDAP
by Edgar Fuß 13 Oct '09

13 Oct '09

I'm somewhat confused regarding Home Directories needed by sieve and setting them for an LDAP userdb. We have system users, passdb ldap, userdb ldap, but home directories are not mounted on the mail server. Now apparently, sieve needs the home directory for .dovecot.lda-dupes. Is there an easier way to give lda/sieve a home directory than setting something along the lines of user_attrs = ...,uid=home=/import/mail/%$/home in dovecot-ldap.conf?

[Dovecot] failing to deliver to one of multiple destinations
by Edgar Fuß 13 Oct '09

13 Oct '09

Is it defined whether, in case a message should be delivered to multiple destinations via a sieve script, and one of those destinations fail, then the whole delivery is to be considered as successful or not? My case: A sieve script forwarding to and external destinations plus local keep. The keep fails (configuration error, wrong homedir, .dovecot.lda- dupes not writable). According to postfix logs, dovecot deliver returned success. The mail was NOT delivered to the local destination and NOT bounced. Is this expected behaviour?
