[Dovecot] dovecot.index mtime
by Matt 15 Nov '07

15 Nov '07

Is there anyway I can get Dovecot to update mtime on dovecot.index everytime a user successfully checks there email? Or perhaps there is a better way to do what I want here. I am working on a script that I want to check when the last time a user checked there email account. If a user has not checked it in say 6 months I want to automatically suspend the account through the MTA. If they start checking it again I also want to automatically reinstate it. What I thought was a good way was to look at the mtime on dovecot.index but a user can be checking there email daily but if they do not receive a new message in say 6 months the mtime will date back to 6 months still. Ran into this with an email address used by a fax machine. So is there a better way with dovecot to determine this? I am using dovecot-1.0.rc29 right now. Matt

[Dovecot] New full text search indexer
by Timo Sirainen 14 Nov '07

14 Nov '07

As described earlier (http://dovecot.org/list/dovecot/2006-December/018055.html) Dovecot nowadays has full text search indexing support in CVS HEAD. Currently there are two backends: Lucene and Squat. Lucene's problem is that standard IMAP SEARCH command can't be used with it without breaking IMAP RFC. So Lucene can be used only with non-standard X-BODY-FAST and X-TEXT-FAST search commands. Squat's code then is quite complex and it's pretty slow. It works with 4 character blocks, so it can answer: - Search string < 4 characters: Can't answer anything - Search string = 4 characters: Definite yes/no - Search string > 4 characters: Probable yes / definite no Since search strings are usually more than 4 characters, Dovecot uses the index only to filter out messages which definitely won't match and then does regular searching for the non-filtered messages. It works ok, but it could work better. The Squat indexes take maybe 30-50% of the mailbox's size. Most of the space goes to UID lists (list of messages matching each 4 character block). For example one UID list could be "2,4-10,20-30". This is already stored in a compressed format by storing the UID numbers relative to previous UID, which allows storing them usually with a single byte per UID, even if the UIDs are large. So, this morning I had an idea how this could maybe be improved with two changes: 1. Don't use 4 character blocks. Instead allow variable sized paths, and keep track of the UIDs for each node in the path. So for example adding "abc" to UID 1 will place the UID 1 to node "a", "ab" and "abc". 2. Use UIDs relative to parent's UIDs. For example if node "a" has UIDs 1,3,5 and "ab" is added for UID 5, the UID is changed to 2 (3th in 1,3,5 list - 1). This can help the compression a lot. The best case scenario for the above example is if "ab" contains also 1,3,5 UIDs. Then it can be written with a single 0-2 range. With these changes, the indexer can be configured to perform in different ways. Text can be indexed in two ways: full words, and substrings within those words (as required by IMAP). I think a useful combination of these would be to index all 4 character substrings and all full words up to 10 characters or so. This kind of an index can answer: - Search string <= 4 characters: Definite yes/no - For X-BODY-FAST / X-TEXT-FAST: - Search string 5-10 characters: Definite yes/no - Search string 11+ characters: Probable yes / definite no - For standard IMAP SEARCH: - Search string 5-10 characters: Definite yes if message contains the key as non-substring, otherwise same as below. This helps only if user does a search that matches a lot of messages. - Search string 11+ characters: Probable yes / definite no UTF-8 text is indexed as bytes, but the path depth can be counted as characters instead of as bytes. I've a test program finished, and unless there are some bugs left I think it shows that this can work pretty well: Squat-like 4 byte substrings (but can answer 1-3 char queries also): Message count: 7495 Index time: 4.19 CPU seconds (7.39MB/CPUs) Node memory: 3014072 bytes (2943 kB) in 90550 nodes UID memory: 8277212 bytes (8083 kB) in 352778 lists Total: 11291284 / 32474899 bytes = 34.77% Indexing the same mailbox file with squat-test gives: - Index time: 9.55 CPU seconds, 9.63 real seconds (3.24MB/CPUs) - 4145192 bytes in 102208 nodes (12.76%) - 7286058 bytes in 305501 uid_lists (22.44%) - 11431250 bytes total of 32474899 (35.20%) So the new indexer is over twice as fast and uses slightly less space. Indexing 4 char substrings and words up to 10 chars: Index time: 5.13 CPU seconds (6.04MB/CPUs) Node memory: 6002804 bytes (5862 kB) in 615501 nodes UID memory: 9044610 bytes (8832 kB) in 519488 lists Total: 15047414 / 32474899 bytes = 46.34% So it takes somewhat more space, but definitely less than having both Squat + Lucene. No substring indexing, words up to 10 chars (Lucene replacement): Index time: 1.39 CPU seconds (22.28MB/CPUs) Node memory: 3297663 bytes (3220 kB) in 548540 nodes UID memory: 1803735 bytes (1761 kB) in 213554 lists Total: 5101398 / 32474899 bytes = 15.71% Is there a need for Lucene anymore with this kind of a speed and disk space usage? :) The above tests are run with everything being indexed except space and control chars (ie. practically space + tab). If only alphanumeric characters are indexed, the total lines are (in same order as above): Total: 7048664 / 32474899 bytes = 21.70% (-13.07%) Total: 9610543 / 32474899 bytes = 29.59% (-16.75%) Total: 3963335 / 32474899 bytes = 12.20% (-3.51%) There are probably still a few optimizations that can be done to get the disk space usage even lower. I did spent quite a lot of time making it use less CPU though. Even tried a bit different coding style variations in the critical functions to get gcc to create faster code.. One interesting thing I noticed was that binary searching a character from a char array was slower than just sequentially going through the characters. I tried adding checks to do it only if the array was big, but it was always slower. Maybe something to do with CPU cache. If you want to try yourself, the test program is in http://dovecot.org/tmp/new-indexer.c

[Dovecot] Using Dovecot as Asterisk PBX voicemail server
by Kenneth Porter 13 Nov '07

13 Nov '07

I'm reading the Asterisk book, 2nd edition, and it describes how one can set up voicemail to be delivered by IMAP to a voicemail folder. Asterisk can monitor flags on the folder so that the "message available" light on one's phone tracks the state of the "read" flag in the folder. One can either dial in for one's voicemail or listen to it from one's favorite IMAP client. (Dovecot is mentioned in the book.) I'm wondering how one would set up auth for this? Asterisk needs to log in to the account to deliver the voicemail and to check its state, but I wouldn't want to put everyone's mail password in plaintext in Asterisk's voicemail.conf file. Would I set up a separate IMAP account for each user to hold their voicemail, and use simple passwords (such as the PIN they use for phone access to voicemail) in the Asterisk config? Or is there a way to set up Dovecot to allow a second user to login to a specific IMAP folder in all accounts, in the same way the local delivery agent has write access to all users' mailbox? Google's page for the book: <http://books.google.com/books?id=vtQxJ3oSm64C&dq=asterisk+book> Dovecot mentions: <http://books.google.com/books?id=vtQxJ3oSm64C&dq=asterisk+book&q=dovecot#se…>

[Dovecot] namespace public folders
by Nikolay Shopik 13 Nov '07

13 Nov '07

Hi list, Here is thing im trying to accomplish. I would like to setup public folders which resposible for delivering mails for some speical addresses like info(a)example.com. And it will be perfect if "seen" status for this folder will be saved per user. I mean if one user read message and set it as read other user should see it still as unread. As I far i know there some limitation in 1.0 tree but not in lates 1.1. My question is can I do such setup with dovecot+postfix. Im really appreciate for simple examples how can i accomplish this kind setup if it possible :)

[Dovecot] v1.1.beta8 released
by Timo Sirainen 13 Nov '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta8.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta8.tar.gz.sig Changes since beta7: - Added a new "raw" mail storage backend which allows opening files/streams as single mail mailboxes. deliver uses this now instead of opening the incoming mail as a mbox. So deliver should be now faster and it doesn't anymore remove Dovecot's private mbox headers if you're not using mbox. - Cache file tracks message expunges again - All kinds of other fixes - Some optimizations I think we're getting closer to v1.1 RCs.

[Dovecot] Missing deliver
by Sean Smitz 12 Nov '07

12 Nov '07

I've installed Red Hat Enterprise Linux 5 on a new server. I'm configuring sendmail and dovecot; however, /usr/local/libexec/dovecot was not created when I installed the dovecot rpm (rpm -Uvh dovecot-1.0-1.2.rc15.el5.x86_64.rpm). The problem is I can't find the deliver executable which is supposed to be in this directory. Any help would be appreciated.

[Dovecot] login_process_size too small on x86_64 Fedora/RHEL

Hello, as described in [253363], login_process_size of 32M is not enough on 64-bit versions of Fedora and RHEL (and possibly other distributions as well). [253363] https://bugzilla.redhat.com/show_bug.cgi?id=253363 As I understand it, there's an intersegment gap between read-only/executable and writable segments of shared libs. That's probably a security feature or something. I found a similar issue here[1], if anyone wants a comment from someone who understands it. [1] http://gcc.gnu.org/ml/libstdc++/2006-12/msg00033.html Shall we just increase login_process_size or make it arch-dependent or something? Regards, -- Tomas Janousek, SW Engineer, Red Hat, Inc.

[Dovecot] v2.0 / Master/config rewrite
by Timo Sirainen 11 Nov '07

11 Nov '07

If anyone's interested, I updated my master/config rewrite to latest Dovecot v1.1 tree and added it to hg: http://hg.dovecot.org/dovecot-master-rewrite/ It probably doesn't work, but with the exception of plugins it compiles anyway. :) I'm thinking that maybe after v1.1.0 I could continue with the rewrite and create v2.0 after all instead of v1.2. Just look at how much cleaner deliver.c is :) http://hg.dovecot.org/dovecot-master-rewrite/file/59ebbfcf21cb/src/deliver/… vs http://hg.dovecot.org/dovecot/file/eb4f1fbeecda/src/deliver/deliver.c Another thing with v2.0 I was thinking about was to change index file formats to be more efficient.

[Dovecot] some mail accesses in dovecot 1.1 stall for a bit (in progress)
by Adam McDougall 11 Nov '07

11 Nov '07

I noticed this in an earlier beta and took a note, and I still see it sometimes in 1.1b4, but it is only occasional so I have not tracked down yet what dovecot is doing. Just a FYI for the list incase others see it and to say that its an issue I tend to track down that I did not see in 1.0, and its been low on my list until now. Sometimes when I login to dovecot and read a message from an imap maildir folder, the message contents do not load for at least 10 seconds, sometimes closer to a minute, but after that first message loads, the rest seem fine in that mailbox. The time seems to vary some, usually longer rather than shorter.

[Dovecot] Outlook can't see namespace folders
by James 10 Nov '07

10 Nov '07

Hi guys i understand that you can't subscribe to the Prefix names of namespace folders right now with dovecot. But for instance if i user outlook express and it can't see the prefix name then it can't see the subfolders of that "prefix folder" either. So even though it can detect and see the subfolders it won't display them cause it can't see the "parent" Is there any fix for this? it's also kind of annoying in thunderbird but at least you can still see the subfolders. TIA James Here's my config # /etc/dovecot/dovecot.conf protocols = imap imaps pop3 pop3s log_timestamp = "%Y-%m-%d %H:%M:%S " first_valid_uid = 100 login_user=vmail mail_extra_groups = mail mail_debug = yes pop3_uidl_format = %08Xu%08Xv mail_location = maildir:/home/vmail/domains/%n/Maildir #default_mail_env = maildir:/home/vmail/domains/%n/Maildir auth default { mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } } # maildir namespace private { separator = / prefix = location = maildir:/home/vmail/domains/%n/Maildir inbox = yes hidden = no } # mbox namespace private { separator = / prefix = "Mbox/" location = mbox:/home/vmail/domains/%n/Mbox inbox = no hidden = no } #public spam folder namespace public { separator = / prefix = /Spam/ location = maildir:/home/vmail/domains/Spam/Maildir/ hidden = no } ssl_disable = no ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem ssl_verify_client_cert = no ssl_cipher_list = ALL:!LOW:HIGH:MEDIUM:+SSLv2:RSA

[Dovecot] Request for variable unique to each server?
by Adam McDougall 10 Nov '07

10 Nov '07

I've been looking for a variable I can use in my dovecot.conf within the INDEX= setting so I can have one index dir per imap server on NFS. I've been looking at http://wiki.dovecot.org/Variables but no variable seems to contain something like server hostname, and I've been hunting for the variable expansion code in dovecot but haven't been able to find it. %l (local IP) won't help me because when using our load balancer, %l is the same IP on all of my servers. %r is close to useful but having a local webmail server on each server means I'd end up with 127.0.0.1 being shared (also I would end up with one directory per unique user/clientIP combo). Is there a variable that holds the server hostname or something else unique per server, or could one be added, or could someone point me at the code? Thanks.

[Dovecot] UTF-8 in dovecot-sieve ?
by Arthur Pétry 10 Nov '07

10 Nov '07

Hi, Reading http://tools.ietf.org/html/rfc3028#section-2.7.2 I thought that out-of-the-box dovecot can filter messages by matching header in UTF-8. But when I tested it, it failed : (I'm using 1.0.5 with sieve plugin) Here is my .dovecot.sieve file : ---------- require ["fileinto", "imapflags"]; if allof(header :contains "subject" "filtre") { addflag "test_1"; } if allof(header :contains "subject" "là") { addflag "test_2"; } if allof(header :comparator "i;ascii-casemap" :contains "subject" "hé") { addflag "test_3"; } ---------- Only the first of the three rules do work. When I try to match a subject string with accent encoded in ISO-8859 like "hélà" : "=?ISO-8859-1?Q?h=E9l=E0?=" there is no match Am I doing something wrong ?

[Dovecot] 1.0beta7 still has SEARCH TEXT not search the FROM
by Asheesh Laroia 10 Nov '07

10 Nov '07

I just tried out 1.0beta7 and erased all my indexes and with fts and fts_squat enabled, and when I SEARCH TEXT in Dovecot, it does *not* find messages where the thing I SEARCH for appear only in the From: header. Timo, can you confirm or deny that you still see this behavior? I did clear my indexes before doing it. -- Asheesh. -- Man is the measure of all things. -- Protagoras

[Dovecot] Dovecot I/O scheduling (all versions)
by mikkel＠euro123.dk 08 Nov '07

08 Nov '07

I have experienced this on all versions of Dovecot that Ive used (1.0 - 1.1b6) using IMAP (its difficult to test if its also there with POP3). What I see is that if there is a peak in disk usage at the time of a specific request that requests stalls. The saturation of disk I/O is momentary but when its done (maybe after one or two seconds) Dovecot still waits for its I/O operation instead of continuing as soon as resources are available. Now, I would expect Dovecot to only wait until there are resources available and not stall for at long time (sometimes it stalls for like 10 seconds, and sometimes completely). This could be OS specific (Im using ZFS and Solaris 10 on Sparc) but it may also be due to the way dovecot is programmed. Theres always plenty of RAM and CPU available so thats not whats causing troubles. Is anyone else familiar with this issue? Regards, Mikkel
